Description

  The present invention relates to a drilling device.

  Conventionally, for the safety of the slope, the surface of the slope is covered with a net, and a 3 to 5 meter long reinforcing rod is placed around the net to cover the face of the slope. The wire rope is covered on the slope by hanging the wire rope around the rod-shaped reinforcing material placed on the slope.

  That is, by covering the slope surface with a net or wire rope, local displacement of the slope is dispersed to prevent sediment discharge.

  Further, by placing a rod-shaped reinforcing material in the ground of the slope, the slope is reinforced to prevent the slope from collapsing.

  Here, in placing this rod-shaped reinforcing material on the slope, a long hole was excavated using an excavator, and the rod-shaped reinforcing material was inserted into the long hole.

  Such a drilling device that excavates long holes uses a drilling device that is as small and light as possible from among ordinary drilling devices so that it can be used even on a site where the work of slope is difficult. It was.

  As an example of such an excavator, there has been a configuration shown below, for example.

  That is, the excavator has a structure in which a suspension type leader operated by a winch is installed on a skid base that is a base, and an auger and a down-the-hole hammer are sequentially attached to the suspension type leader.

  Here, the leg portion of the suspended leader has a pin support structure, and the skid base and the leader intermediate portion are connected by a piston rod of a hydraulic cylinder.

  When excavating using this excavator, first, the piston rod is expanded and contracted to adjust the front / rear inclination of the suspended leader, and the down-the-hole hammer is moved to the excavation position.

Then, the down-the-hole hammer is rotated by the auger and the excavation ground is excavated by the weight of the down-the-hole hammer while the auger is lowered by the winch (see, for example, Patent Document 1).

  However, although the conventional drilling rig was selected and used as small and light as possible from ordinary drilling rigs, it was not dedicated to the slope with a poor footing. As expected, there was a problem that the small turn was not effective and the weight of the excavator made the work difficult.

  In particular, when excavation work is performed on natural slopes in cliffs and forests, the work of transporting the drilling equipment to the excavation site has to be carried out by a person, which requires a lot of time and labor. . In addition, when excavating near-vertical excavation ground such as steep slopes and cliffs, it is necessary to install an assembly scaffold to secure a scaffold for work, and assemble the excavator. It was extremely difficult to transport to the point where the excavation work was performed on the scaffold.

  Furthermore, the excavation work on the assembly scaffold is particularly unstable, so excavation work that supports the drilling device while maintaining the balance of one's body is extremely difficult and dangerous for the operator. The size and weight of the drilling rig was a heavy load.

  Therefore, in the present invention according to claim 1, the excavator includes a left and right cylinder, an operating rod provided in parallel with the cylinder, a connecting portion for connecting a piston rod from the left and right cylinders to the operating rod, An excavator mount that is fixed to the rod and is slid on the peripheral sides of the left and right cylinders, and an excavator mounted on the mount.

  In the present invention according to claim 2, at least the left and right cylinders, the operating rod, the excavator mount, and the excavator are configured to be separately assembled.

  In the present invention according to claim 3, the excavator is mounted on the assembly scaffold standing on the sloped slope so as to be displaceable via the clamp mechanism.

  The present invention is implemented in the form described above, and has the following effects.

  (1) That is, according to this invention which concerns on Claim 1, excavation equipment is for connecting the left and right cylinders, the operating rods arranged in parallel to the cylinders, and the piston rods from the left and right cylinders to the operating rods. The excavator mount that is fixed to the connecting part and the operating rod integrally and slides on the peripheral side of the left and right cylinders, and the excavator mounted on the mount, can be easily mounted on the excavator mount. The mounted excavator can be moved forward and backward by a cylinder that is a telescopic mechanism. In particular, the excavator mount can be stably moved while sliding on the peripheral side surfaces of the left and right cylinders. As a result, the cylinder can be used both as an expansion / contraction mechanism and a guide, and it is not necessary to provide a new guide, so that the construction of the excavator can be further simplified and the excavator can be reduced in size and weight. Therefore, excavation work can be facilitated and performed safely and efficiently. Moreover, the excavator can be supplied at a low cost.

  (2) According to the second aspect of the present invention, since at least the left and right cylinders, the operating rod, the excavator mount, and the excavator are configured to be separately assembled, the excavator is disassembled and disassembled. Assembling is possible, and when excavating equipment is transported to work sites such as slope slopes and cliffs, the excavating equipment can be disassembled and transported in parts, and can also be transported by humans As a result, transportation work can be facilitated.

  (3) According to the third aspect of the present invention, the excavator is mounted on the assembly scaffold standing on the slope slope so as to be displaceable via the clamp mechanism, so that the operator supports the excavator during work. There is no need, and the work can be facilitated and performed safely. Further, since the assembly scaffold can be a part of the excavator, the excavator can be reduced in size, weight, and cost.

  The excavator according to the present invention is integrated with the left and right cylinders, which are telescopic mechanisms, an operating rod provided in parallel with the cylinders, a connecting portion for connecting piston rods from the left and right cylinders to the operating rod, and the operating rod. And an excavator mount that slides on the peripheral side surfaces of the left and right cylinders, and an excavator mounted on the mount.

  The left and right cylinders operate the same at the same timing, and the piston rods that are the operating parts of the left and right cylinders perform the same expansion and contraction motion at the same timing.

  These piston rods are connected and fixed to each other by connecting portions.

  In addition, the connecting portion has an operating rod connected and fixed above the left and right cylinders so as to be juxtaposed with these cylinders, and the operating rod is operated in conjunction with the expansion and contraction of the left and right piston rods. To be able to.

  And the excavator mount which mounts an excavator is fixed to the front-end | tip part of this operating rod.

  Here, on the left and right sides of the lower part of the excavator mount, semicircular arc-shaped grooves configured to slide on the peripheral side surface of the cylinder are provided.

  As a result, the excavator mount can be stably moved while being guided by the left and right cylinders when the excavator mount is advanced and retracted by the expansion and contraction mechanism of the cylinder.

  In this way, the left and right cylinders serve both as an expansion / contraction mechanism and an excavator mount guide, so that the excavator can be reduced in size, weight, and cost.

  An excavator for excavating the excavation ground is mounted on the excavator mount, and the excavator can be moved forward and backward by contracting / extending operation of the left and right cylinders, which are telescopic mechanisms.

  When excavating the excavation ground using the excavator configured as described above, the excavation hole is excavated while the tip of the excavator is brought into contact with the excavation ground and the excavator is driven to excavate the excavation ground. Along with the progress, the excavator is advanced to the excavation ground by the contraction operation of the cylinder, which is an expansion / contraction mechanism, and further excavation is performed to excavate the excavation ground to a predetermined depth.

  When excavation is completed, the excavator is retracted by the extension operation of the cylinder, which is an expansion / contraction mechanism, and the tip of the excavator is extracted from the excavation hole.

  In particular, since the excavator according to the present invention is configured so that at least the left and right cylinders, the operating rod having the excavator mount, and the excavator can be assembled separately, they can be disassembled and assembled. .

  Therefore, when excavating excavation ground such as cliffs and slope slopes in forests, the excavator is further reduced in size and weight by disassembling and dispersing each part. The device can be transported manually to a poorly grounded excavation ground.

  Furthermore, the excavation apparatus according to the present invention can be mounted on an assembly scaffold that is erected to secure a scaffold for work via a clamp mechanism.

  Therefore, it is not necessary for the operator to support the excavator when performing the excavation work, and the excavation work on the assembly scaffold with an unstable scaffold can be facilitated and the excavation work can be performed safely.

  And since an assembly scaffold can be utilized as a part of excavation apparatus in this way, the structure for supporting an excavation apparatus can be abbreviate | omitted. In addition to this, as described above, it is not necessary to newly provide a guide by using the cylinder, which is an expansion / contraction mechanism, as a guide, so that the excavator can be greatly reduced in size and weight.

  As a result, it is possible to provide a drilling device suitable for difficult excavation work on a slope with a poor scaffolding or a vertical slope that requires an assembly scaffolding, thereby facilitating and making the excavation work easy and safe. . Moreover, the excavator can be supplied at low cost.

  In driving these left and right cylinders 1, 1, an air compressor (not shown) that is configured separately from the excavator A and is installed near the lower end of the excavation ground is used. 1 and 1 are connected to each other by a connecting pipe (not shown), and compressed air is supplied from the air compressor to the left and right cylinders 1 and 1 respectively.

  As shown in FIG. 2, the cylinder 1 includes a cylinder body 12 and a piston rod 13 that is an operating portion, and the piston rod 13 performs expansion and contraction movements by entering and exiting compressed air supplied by an air compressor.

  At this time, since the compressed air enters and exits at the same timing in the left and right cylinders 1, 1, the left and right piston rods 13 perform the same expansion and contraction at the same timing.

  As shown in FIG. 5, the left and right piston rods 13 are connected to each other by a connecting portion 3 that connects the respective end portions.

  As shown in FIG. 6, the connecting portion 3 is a substantially base type having a protruding portion on the upper side, and a piston rod cutout portion 14 is provided by cutting out the center portions of the left and right ends, respectively. The distal ends of the left and right piston rods 13 are inserted and fixed to 14, respectively.

It is fixed to the connecting part 3.

  Therefore, when removing the piston rod 13 from the connecting portion 3, it can be easily disassembled by removing the connecting portion fixing nut 15.

  In this way, the piston rod 13 and the connecting portion 3 can be easily disassembled and assembled.

  Further, the connecting portion 3 is provided with a through hole 17 for penetrating the operating rod 2 in the center of the projecting portion of the base mold, and the operating rod 2 is inserted into the through hole 17 from the cylinder body side. Thus, the front end portion is penetrated and fixed, and the left and right cylinders 1 and 1 are arranged side by side.

  That is, an operating rod fixing long hole 18 which is a long hole penetrating in the vertical direction is formed at the tip of the operating rod 2 penetrating the connecting portion 3, and is fixed to the operating rod fixing long hole 18. The operating rod 2 is fixed to the connecting portion 3 by inserting the operating rod fixing rod 19 for use from above.

  As described above, when the operating rod 2 is fixed to the connecting portion 3, the operating rod fixing rod 19 is simply inserted into the operating rod fixing long hole 18. Assembly can be done easily.

  Further, as shown in FIGS. 5 and 7, an excavator mount 4 for mounting the excavator 5 is passed through and fixed to the other tip of the operating rod 2.

  Thus, since the excavator mount 4 integrally fixed with the excavator mount 4 is fixedly connected to the connecting portion 3 connected to the piston rod 13, the excavator mount 4 is advanced and retracted by the expansion / contraction mechanism of the cylinder. can do.

  As shown in FIG. 8, the excavator mount 4 has a semi-cylindrical guide groove 21 that slides on the peripheral side surfaces of the left and right cylinders 1 and 1 on the lower left and right sides of the frame 20 on which the excavator 5 is mounted. Are connected to each other.

  As a result, the excavator mount 4 can move stably with the cylinder 1 as a guide when the excavator mount 4 is advanced and retracted by the cylinder 1 which is a telescopic mechanism. Moreover, a resin interference plate 22 is affixed to the lower surface of the guide groove 21 in contact with the peripheral side surface of the cylinder 1 to reduce the coefficient of friction between the peripheral side surface of the cylinder 1 and the lower surface of the guide groove 21. Sliding between the cylinder 1 and the guide groove 21 is made smooth.

  Thus, since the excavator A can also use the cylinder 1 as a guide, it is not necessary to newly provide a guide, and the excavator A can be reduced in size, weight, and cost.

  Further, the guide groove 21 is configured such that the contact surface with the cylinder 1 is equal to or less than a half of the peripheral side surface of the cylinder 1. As a result, when the connecting portion 3 having the excavator mount 4 and the cylinders 1 and 1 are assembled, the excavator mount 4 can be assembled so as to be covered from above the left and right cylinders 1 and 1. On the other hand, when removing the excavator mount 4 from the state in which the excavator mount 4 is assembled to the cylinder 1, the excavator mount 4 can be easily removed by moving the excavator mount 4 vertically upward. In this way, the excavator mount 4 and the cylinder 1 can be easily disassembled and assembled.

  Further, the excavator mount 4 is provided with an excavator fixing plate 23 for fixing the excavator 5 on the front side surface in the moving direction. The excavator fixing plate 23 is provided with excavator connecting holes (not shown) for connecting the excavator 5 on the left and right sides.

  As shown in FIG. 1, the excavator 5 mounted on the excavator mount 4 has a rod-shaped excavation rod 25 facing the excavation ground mounted on an excavator main body 24 having a drive mechanism. A bit 26 made of a hard material is attached to the tip, and the excavator body 24 drives the bit 26 via the excavation rod 25 to hit the excavation ground for excavation.

  On the left and right sides of the front surface of the excavator main body 24, front connection recesses (not shown) each provided with a screw thread on the side surface of the recess penetrating in a columnar shape are provided.

  Further, a rear connection recess (not shown) is provided in the center of the rear surface of the excavator main body 24 in which a screw thread is provided on the side surface of the recess penetrating in a cylindrical shape.

  When the excavator 5 is mounted on the excavator mount 4, as shown in FIG. 9, the front connecting recess of the excavator main body 24 and the excavator connecting hole of the excavator fixing plate 23 are communicated with each other, and the washer 27 Then, the excavator connecting screw 28 is screwed and fixed to the front connecting concave portion, and the excavator 5 is connected and fixed to the excavator mount 4.

  Further, the rear connection screw hole of the excavator main body 24 and the excavator connection hole (not shown) for connecting to the excavator 5 drilled in the rear surface of the frame 20 of the excavator mount 4 are communicated. Then, the excavator connecting screw 28 ′ is screwed and fixed to the rear surface connecting recess through the washer 27 ′, and the excavator 5 is connected and fixed to the excavator mount 4.

  Therefore, since the excavator 5 is connected and fixed to the excavator mount 4 at two locations on the front surface and one location on the rear surface, a total of three locations, the excavator 5 can be stably and firmly fixed on the excavator mount 4.

  As described above, when the excavator 5 is mounted on the excavator mount 4, the excavator connection screws 28 and 28 ′ are used to fix the excavator 5, so that the excavator 5 and the excavator mount 4 are disassembled and assembled. Can be done easily.

  As described above, since the working rod 2 fixed integrally with the excavator mount 4 is connected to the piston rod 13, the excavator 5 mounted on the excavator mount 4 includes left and right cylinders that are expansion and contraction mechanisms. It can be moved forward and backward by 1, 1 telescopic operation.

  Therefore, the excavator A advances the excavator 5 to the excavation ground by the contraction operation of the left and right cylinders 1 and 1 as the expansion and contraction mechanism as the excavation hole 5 proceeds while excavating the excavation ground. The excavation ground is excavated to a predetermined depth by further excavation.

  When the excavation is completed, the excavator 5 is retracted by the extension operation of the left and right cylinders 1 and 1 which are expansion and contraction mechanisms, and the excavation rod 25 and the bit 26 are extracted from the excavation hole.

  Furthermore, the excavator A of the present invention has a clamp mechanism for mounting on the assembly scaffold, and can be mounted on the assembly scaffold so as to be displaceable.

  That is, when the excavation ground is in a state of being nearly vertical, such as an inclined slope or a cliff, an assembly scaffold is installed so that the excavation ground can be operated. Since the excavation work with such an assembly scaffold is extremely unstable and unstable, the excavation work performed while supporting the body while supporting the excavator A is a dangerous work with difficulty. Therefore, mounting the excavator A on the assembly scaffold eliminates the need for the operator to support the excavator A and facilitates the work.

  Actually, when the excavator A is attached to the assembly scaffold, the excavator A is attached to the assembly scaffold so as to be displaceable via the universal clamp 29 between the excavator A and the assembly scaffold.

  As shown in FIG. 10, the universal clamp 29 has two connecting bars 32 each having a cylinder support 30 that supports the cylinder 1 and an assembly scaffold support 31 that supports the assembly scaffold, which are rotatably connected. It is configured to be connected while maintaining an interval.

  The cylinder support 30 and the assembly scaffold support 31 have the same configuration, a substantially semicircular fixed bending portion 33, and a substantially semicircular movable bending portion pivotally attached to the end of the fixed bending portion 33. 34 and an end fixing portion 35 that can fix the open end of the fixed bending portion 33 and the open end of the movable bending portion 34.

  A notch 36 is provided at the tip of the other end of the movable bending portion 34.

  The end fixing portion 35 includes a fixing screw 37 pivotally attached to the other end of the fixed bending portion 33, a washer 38, and a nut 39.

  When the universal clamp 29 is attached to the cylinder 1, the movable bending portion 34 is opened with the end fixing portion 35 of the cylinder support portion 30 opened, and the cylinder 1 is inserted into the movable bending portion 34 and the fixed bending portion 33. The distal end portion of the fixing screw 37 of the end fixing portion 35 is inserted into the notch portion 36 of the movable bending portion 34, and the washer 38 is inserted from the distal end portion of the fixing screw 37, and then the nut 39 is attached to the fixing screw 37. Screw in and fix.

  As with the cylinder support portion 30, the assembly scaffold support portion 31 opens the movable bending portion 34, accommodates the pipes constituting the assembly scaffold in the movable bending portion 34 and the fixed bending portion 33, and moves the movable bending portion at the end fixing portion 35. By fixing the portion 34 and the fixed bending portion 33, the assembly scaffolding support portion 31 is attached.

  In this way, the universal clamp 29 is attached to the cylinder 1 and the pipe of the assembly scaffold in front and rear of each of the left and right cylinders 1 and 1, so that the excavator A is connected to the assembly scaffold at four locations and is stable. And fixed.

  At this time, by attaching the assembly scaffolding support portion 30 to a pipe suitable for the assembly scaffolding in accordance with the position of the excavation hole, the operator does not need to support the excavation apparatus A when performing the excavation work. it can.

  Therefore, the operator is freed from the weight of the excavator A, can work on the unstable assembly scaffold, and can work safely.

  Thus, since the assembly scaffold can be used as a part of the excavator A, the configuration of the excavator A can be simplified, the excavator A can be reduced in size and weight, and the slope with a poor scaffold can be obtained. The excavation work at can be facilitated. Further, the cost of the excavator A can be reduced.

  The excavator A according to the present embodiment has the above-described configuration, and particularly includes the right cylinder 1, the left cylinder 1, the cylinder fixture 6, the connecting portion 3, and the excavator mount 4. The operating rod 2 and the excavator 5 are configured to be assembled separately.

  Therefore, the excavator A can be disassembled and assembled. Moreover, as described above, each component can be easily disassembled and assembled. As a result, when the work site is inclined slope, cliff, etc., the excavator A can be further reduced in size and weight by disassembling the excavator A, and a person can carry the disassembled parts. As a result, the transportation work of the excavator A to a work site with a poor scaffold can be facilitated.

  A method for securing the slope using such an excavator A will be described in the case of laying a wire rope on the slope.

  First, a plurality of imaginary lines having predetermined intervals in the horizontal direction are provided on the slope, and a plurality of excavation holes are excavated using the excavation apparatus A of the present embodiment while maintaining the predetermined intervals on the imaginary lines. At this time, excavation is performed so that the positions of the excavation holes drilled on the virtual line are alternated in the virtual line moving up and down.

  Next, mortar which is a filler is poured into the excavated excavation hole, and further, a rod-shaped bar-shaped reinforcing material having a length of 3 to 5 m is placed.

  Next, when the wire rope is passed over these rod-shaped reinforcing members, from one rod-shaped reinforcing member to the rod-shaped reinforcing member placed in the shape of a hexagonal apex around the rod-shaped reinforcing member, each linearly Hang the wire rope.

  In this way, by reinforcing the slope by placing a rod-shaped reinforcing material on the slope, by laying a wire rope around these rod-shaped reinforcements and covering the wire rope all over the slope, The slope can be kept safe by preventing the collapse of the slope and the outflow of sediment.

  As described above, the method of drilling a drill hole on a slope with a drilling device and placing a rod-shaped reinforcement on the drilled drill hole has been described. In addition to the method of placing a rod-shaped reinforcing material in the excavated drilling hole, the excavator body is equipped with a disposable excavating rod and bit and the drilling hole is excavated on the slope, and after the excavation is completed There is also a method in which the base end portion of the excavating rod is detached from the excavator body and the excavating rod and the bit are buried in the ground as a rod-shaped reinforcing material.

  In this way, the excavator that allows the excavator body and the excavation rod to be detachable is provided with a concave portion for attaching an excavation rod penetrating in a cylindrical shape at the tip of the excavator main body, and on the side surface of the concave portion for mounting the excavation rod. The screw thread is cut into a screw receiving portion, and the base end portion of the excavation rod is processed into a screw shape to form a screw portion. The screw portion of the excavation rod is screwed into the excavator mounting recess of the excavator body. By combining them, the excavation rod is attached to the excavator body.

  Therefore, it is easy to attach and detach the excavating rod to the excavator body, and repeat the installation of the excavating rod to the excavator body, excavation of the excavation hole, and the detachment of the excavating rod from the excavator body, and the rod surface on the slope A drilling rod and a bit as a reinforcing material can be placed.

  In addition, a bit having an inner diameter larger than the inner diameter of the excavation rod is attached to the tip of the excavation rod, and when excavating the excavation hole, a gap is formed between the excavation rod and the excavation hole. The

  Therefore, when the excavation is completed, the excavation rod can be detached from the excavator body, and the mortar can be poured into the gap to firmly fix the excavation rod and the bit to the excavation hole.

  It can be used for excavating sloped slopes with poor scaffolding, especially vertical slopes that require assembly scaffolding.
