Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a transportable lane separation device and a method for transporting said separation device. Devices of this type are necessary for the movement of lane separation devices on bridges or main roads during rushes.

[Prior art and problems to be solved]

One method of moving existing lane markers consists of manually lifting the originally installed marker and manually placing the marker in the new position. This specialized task involves some risk to the operator who manually moves the lanes, and also requires a large number of personnel to successfully complete the task. Various forms of obstacle devices have been proposed to overcome this problem.

U.S. Patent by Eschen
No. 4004857 discloses that a groove is formed in the road at right angles to the flow of traffic, and a hydraulically driven trolley is installed in said groove for movement along this groove. An elongated obstruction is coupled to a post connected to the carriage such that movement of the carriage within the groove moves the obstruction to its new position.

This equipment requires excavation of the road for the installation of trenches and the necessary hydraulic equipment, the nature of obstacles that do not have adequate protection against impact from vehicles striking them, and It suffers from some drawbacks, such as a susceptibility to debris clogging of the gutter which can impede effective transport of the equipment.

A device that does not require digging up the road surface is disclosed in Ferrari U.S. Pat. A connected trolley hoist is running. The trolley hoist cooperates with another trolley hoist to lift the obstacle and move it to a desired position.

Although this device does not require any digging into the road surface, it has drawbacks such as the cost of installing the gantry and hoist, the maintenance of the device, and the need to take measures against the climatic conditions of the hoist.

Another solution is proposed in U.S. Pat. No. 4,017,200 by Woods, in which a vehicle with an S-shaped transfer device moves the obstacle to a new location onto the transfer device. Used to move by sliding. However, this device uses obstacles in the form of elongated channels, the members of which are interconnected and vertically slidably connected;
They are installed in the grooves that form the boundaries between lanes on the road surface. To move this type of obstacle, the sloped member of the transfer device slides along the groove to lift the obstruction member from its base, and as the sloped member moves along the groove, the obstruction member is tilted. It slides up onto the object, passes through the bridge member, and places it into position in another groove on the road surface with another inclined member. When this transfer occurs, a small block member is transferred by a similar ramp/bridge device to fill the groove in which the obstruction member exited to the level of the road surface.

This device still suffers from the problem of digging into the road surface, and due to the nature of the obstacles in each road groove and the two inclined members of the block member transfer device, it is difficult to pull the transfer device along the road. There will be considerable problems. Furthermore, there is a possibility of deforming the obstacle member,
The impact of vehicle collisions is significant, which can have a significant impact on movement along the tilt/bridge device.

U.S. Patent No. for Wiswell
Another device has been proposed as described in US Pat. No. 2,931,279. This device uses an S-shaped transfer device that transfers relatively flat metal separator modules that are mounted on a road surface hinged to each other. These modules are lifted at their base and slid onto rollers to be transported along the conveyor channel to their new position.

Although this device is an improvement over the previously described devices, it does not provide a completely effective device.

The present invention comprises separating device modules in which adjacent modules are mutually pivotally movable and are coupled together to form an elongated separating device for lane separation; A movable lane separation device, each having a bottom surface adapted to rest directly on the road surface, wherein a transport means is provided above the bottom surface of the module, thereby transporting said module into a generally S-shaped elongated transport device. the separating device is moved from a first on-road position to a second on-road position by being pulled up by a module and slid along the transfer device as the transfer device moves on the road; An improved method comprising two grooves located on either side of the module adjacent to the top and extending substantially horizontally with each module, into which grooves the corresponding sliding means of the transfer device fit. To provide a lane separation device that can effectively separate lanes.

In another form, the present invention provides a movable lane separation obstacle system having a plurality of lane separation obstacle modules hinged to each other, each module having a plurality of lane separation obstacle modules adjacent to the top of the module. It has a T-shaped protrusion formed by two elongated grooves extending longitudinally along both sides, whereby the module can be transported into said elongated grooves by means of a roller, and further includes an adjacent elongated groove. It includes a plurality of locking members hingedly connected to each other, each locking member being in the form of an inverted channel closely fitting over a T-shaped projection, each locking member having at least two downwardly extending elongated projections. the protrusion is slidably disposed within corresponding holes in at least two adjacent modules, and the locking member straddles the at least two modules to substantially secure the modules to each other. A located and movable lane separation obstacle system is provided.

〔Example〕

The invention will now be described by way of example with reference to the accompanying drawings, in which: FIG.

Each lane separation device is made up of individual modules 1 which are hinged together by a pair of links 2. The required number of modules 1 are connected to form a separation device of appropriate length.

A modular embodiment of the separation device can be constructed as shown in FIG. In this figure, each module has two ramps 3 to ensure a smooth ride in case a car tire accidentally runs over the separating device.
has.

The central portion 4 extends upwardly from the side portions 3 creating an easily recognizable obstruction. Preferably the separator module has a height of 800 mm, a width of 600 mm and a length of approximately 1
It is m.

However, any suitable dimensions may be used as long as adequate stability of the separation device is achieved.

The lane separator module can be made of any suitable material such as concrete, plastic or sheet metal.

Preferably, the module is constructed of reinforced concrete, with hinges 2 formed on a single metal rod at each end of the module, and reinforcing rods provided to provide adequate strength.

To facilitate movement of the lane separator, each module has two grooves 16 formed on either side of the central portion 4 to provide a T-shaped projection extending from the central portion 4 and along the length of the separator. It forms part 5.

A transport mechanism such as that shown in FIG. 4 may be used to transport the lane separation device. The transfer mechanism consists of a roller conveyor 6 having a series of rollers 15 mounted at an angle to the channel 7 as shown in FIGS. Each roller is positioned to engage the circular portion 8 at the neck of the T-shaped portion, as shown in FIG.

Basically, the transfer mechanism is S as shown schematically in Figure 2.
It is letter-shaped, and its total width 9 corresponds to the distance between the lanes. This is preferably mounted under the trailer as schematically shown in FIG. Preferably, the front section 10 and the rear section 11 are kept within an acceptable width for bending them into the body of the trailer and moving on the road.

To move the lane separator from one side of the lane to the other, drive a vehicle with a transfer mechanism mounted under the trailer or indexed to the rear of the trailer and move the leading roller 15 onto the T-shaped protrusion. 5 is simply engaged. As the transport mechanism is moved along the lane, the lane separator passes through the roller conveyor 6 and is lowered onto the opposite side of the lane at the rear section 11.

Preferably, the vehicle or trailer supports channels under the wheels, with an inlet extending to one side of the vehicle and an outlet extending to the opposite side of the vehicle to allow the vehicle to drive in the center of the lane and reinstall the lane separation device. be able to. However, in some cases it may be necessary to position the channel in a different relationship to the vehicle.

FIG. 3 illustrates an alignment mechanism that can be used to align the lane separation device when the lane separation device is kicked out of position by the vehicle or other environment due to an accident.

The means for removably securing the preferably transportable lane obstruction module is required to provide stability against lateral movement due to vehicle impacts.

Thus, in one embodiment of the invention employing a lane separation device module having a protrusion extending along the top, an inverted channel is fitted over said protrusion. Use an elongated rod member. The elongated locking member is hinged to two adjacent locking members, and the staggered locking members secure the lane separation device modules together.

Instead of a locking member connected to the top of the module, the locking member may engage a recess in the bottom of the module.

As shown in FIG. 6, the obstacle module 1 of the movable lane separation device has a shape similar to that described with reference to FIGS. 1 and 5. However, these modules have a top 25 made of heavy steel plate rather than concrete. The top 25 has a protrusion 19 extending along its length and embedded and consolidated in the concrete 18 of the module;
The top part 25 and the module 1 are reliably joined. The top 25 of the module 1 and the neck 17 form a transfer groove 16, in which FIGS.
Transfer rollers or other suitable transfer devices may be engaged in a manner similar to that described in connection with FIGS. 4 and 5.

Elongated locking members 23 in the form of inverted channels 24 are used to secure adjacent modules together. These are pivotally connected to each other by elongate members 42 which are pivotally connected to bolts 21 on adjacent locking members 24 by means of nuts, as shown, for example, in FIG. The locking member 24 has almost the same length as the module 1, and the top 25 is the same as the slotted member 24.
When recessed and positioned so that the locking member 23 bridges adjacent modules 1, the modules are secured against each other so that they cannot pivot laterally.

Preferably, the locking member 23 is slidably mounted vertically to an adjacent module by a rod 22 slidably retained in a hole 28 in the module as shown in dotted lines in FIGS. 7 and 9. It will be done.
In the illustrated embodiment, each locking member 23 includes a locking member 23 that fits into a respective hole in an adjacent module.
It has a protruding rod for books.

The side members 20 of the channel 24 extend downwardly to engage the transfer groove 16 when the locking member is in its locked position.
is covered.

Another embodiment of the lane separation obstacle system is shown in FIG. This is similar to that shown in FIG. 6, except that the module top 26 and the transfer groove 16 are both made of metal plate 27.

The leading locking member 30 is shown in FIG. This member 30 has a tapered leading edge 31 which engages a roller or other device which may be mounted on a transfer device similar to that described above when attempting to move a movable obstacle. Thus, as the transfer device moves along the module, a ramp (not shown) engages under the leading edge 31 of the locking member 30 and lifts the locking member above the top 34 of the module, allowing the locking member to move on either side of the channel. 20 underlines 33 are placed on a plurality of rollers 32.

The module's transfer groove 16 then engages a transfer device (not shown) and the module and locking member are transferred in the same manner as described above. When the module is lowered into its new position, the locking member is lowered into locking engagement with the top of the module;
A positioning roller is used to positively position the channel into locking engagement. To facilitate positioning of the locking member, the channel
It may have tapered or flared sides as shown.

As shown in FIG. 8, the sides 20 of the channel extend downwardly beyond the transfer groove 16 and abut on the shoulder 35. The module 1 has a concrete surface covered with a steel plate above the shoulder 35 to protect the top and the transfer channel.

To facilitate movement of the rod 22 through the bore 28, a polyurethane bush 29 is attached to the bore 28.

The module may be of the form shown in FIG. 10, in which the locking member 23 is located in a longitudinal groove 37 located at the bottom of the module.

As shown in FIG.
The channel member 36 has a shape corresponding to the outer shape of the channel member 36 .
As in the previous embodiment, the locking member includes a protruding rod 39 slidably located within a hole 38 in the module.
, which are located bridging the two modules. The rod 39 terminates in a recess 40 located in the upper surface of the module and has retention means such as a disc 41 located at or near the free end of the rod to prevent rod 39 from slipping out of hole 38 when the module is lifted. It seems like there is no such thing. Preferably, the recess 40 is capped to prevent objects from entering therein.

Modifications of the embodiment shown in FIG. 10 are shown in FIGS. 11 and 12.
As shown in the figure, the length of the locking member 23 is in this case slightly less than twice the length of the module 1. Therefore, it is only necessary to secure the module to the locking member at every other obstacle. This embodiment is therefore less expensive to manufacture than the embodiment shown in FIG. 10, in which every module must have a locking member attached to it.

The module 1 holding the locking member 23 is in the groove 3
7 has a generally rectangular recess 42 molded into the base thereof. A hole 43 passes through the wall of the module to form a recess 4.
2, a grid 44 of reinforcing bars is used as shown in FIG. 12 to give the module appropriate strength. Hinge 45 and 46 are the first
As shown in Figure 2, it is formed as a single piece made of steel that passes through the module.

The locking members 23 are in the form of inverted channels 36 and each have two grooved projections 47 which fit into recesses 42 and have rods 48 passing through said holes 43 and said grooves 49. The lock member 3
6 is held in module 1. Thus, when the module is lifted, the locking member 23 is disengaged from the groove 37 and the protrusion 47 slides over the rod 48 which abuts the end of the groove 49. Polyurethane plugs 50 may be used to plug both ends of rod 48.

Therefore, in this type of movable lane obstruction system, the transfer device as described above will move across the lane as long as the locking member 23 is raised to a sufficient height to hang out of the groove 37. It can be used for. Once the modules have been fed along the transfer device to a new position, they simply slide down to the ground where the locking members are automatically engaged within the recesses.

Without departing from the scope and spirit of the invention, the modules and locking members may be modified to
Obviously, modifications can be made by changing the mounting method or the materials of construction.
