DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic steel plate polishing device, and more particularly, to a steel plate automatic polishing device.
The present invention also relates to automatic polishing of welded parts of steel plates used in other steel structures to uniformly remove primers adhering to the steel plates to ensure good welding.

Conventionally, the welded parts of the steel plate were polished manually by a worker holding a polishing roller, but this was not only inefficient, but also caused variations in polishing depending on the worker. There was a problem in efficiently and uniformly removing primers and other stains that sometimes adhere to steel plates.

In order to solve the above-mentioned problems, the present invention attaches a polishing section with a polishing belt driven by a motor attached to a traveling frame that runs gently over a steel plate at a constant speed, and automatically polishes the top surface of the steel plate uniformly. At the same time, the dust of the primers peeled off and removed by the abrasive belt is collected by a dust removal device also provided on the traveling frame.

The details of the present invention will be explained below based on the embodiments shown in the drawings. Figures 1 to 4 show an automatic steel plate polishing device according to the present invention, and the device has a total of four wheels on the lower front, front, left, and right.・

Further, on one side or both sides of the traveling body part (■), a guide means @ is provided with a guide column (O) having a guide roller (■) at its lower end that rotates horizontally in contact with the side end surface of the steel plate (■). If necessary, the column 0 is of a sliding type and expands and contracts in the lateral direction so that the distance between the guide rollers 2 can be adjusted according to the width of the steel plate.

In addition, a body lifting device (■) is provided at the lower center of the front and rear sides of the traveling body (1), respectively, and by rotating the lever (■) provided on the fixed box (■), the lower part of the box (■) can be lifted up. In this case, a rotating wheel [phase] provided perpendicularly to the wheel ■... is arranged to move up and down.

That is, the fixed box (■) is fixed to the traveling side body part (■), and the abbreviated operating lever (■) is inserted laterally, and the box (■)
Inside the box, a cam (not shown) is installed externally on the lever ■, and on the other hand, a plate (not shown) that rotates around one point and returns to rotation due to the force of a spring is attached to the box ■.
By installing a rotary ring [phase] on the lower surface of the plate, when the operating lever (■) is rotated, the cam rotates together with the lever (■) to press the plate downward, and the force of the spring is applied. A plate provided with a rotating wheel [phase] is rotated by a certain angle against the resistance, and the rotating wheel [phase] is made to land firmly on the steel plate, so that the front or rear wheels float. There is.

Note that @ is the operation panel provided at the rear of the traveling side body part ■.

On the other hand, the polishing section (■) is provided on one or both sides of the traveling side body (■), and is configured to continuously polish the upper surface of the steel plate (■) with an endless rotating polishing belt. , the polishing parts (2) are arranged on both sides of the traveling side body part (2).

In other words, a front polishing roller (■) is placed on the front side of the traveling body (1).
A rear polishing roller ■ is provided at the rear of the side surface, an intermediate roller [phase] is arranged between both polishing rollers ■■, and a polishing belt is stretched around each roller ■■ [phase] in a substantially triangular shape. The front polishing roller ■ is placed a certain distance above the top surface of the steel plate ■, and is directly connected to the polishing motor 0 fixedly installed inside the traveling side body ■, while the rear polishing roller ■ is attached via a bearing part [phase] to the rear part of a swinging rod [phase] having a box-like, channel-like, etc. shape that is placed on the side of the traveling side body part ■, and the rear polishing roller 0
The upper surface of the steel plate is polished in this area.

Although the front polishing roller (2) directly connected to the motor [phase] is provided separately from the swinging rod [phase] in the embodiment, it can also be provided integrally.

The swinging rod [phase] is attached to the running side body part ■ via the swinging mounting part O provided at the upper part of the front part of the swinging rod [phase]. The swinging rod [phase] swings at a constant angle back and forth and left and right around the mounting part ◎, and as a result, the position of the rear polishing roller ■ attached to the swinging rod [phase] relative to the top surface of the steel plate ■ can be adjusted. It is possible.

In other words, the swing mounting part O has two side plates OO and one upper plate [phase].
Therefore, a roughly eye-shaped pedestal O is attached to the top surface of the swinging rod [phase] with a pin [phase] inserted through the lower part of the side plate O so as to be able to swing back and forth, and the pedestal O is attached to the upper plate [phase] of the pedestal [stock]. In addition to drilling two oblong holes O in the front and rear, two standing plates [phase] [phase] are erected at the front and rear ends of the upper surface of the pedestal [phase], and for the vertical plate 0 [phase]. Similar to the above-mentioned pedestal, a mass production [phase] is arranged with a side plate OO and an upper plate [phase], which are approximately mouth-shaped.
and the above-mentioned vertical plate [phase] are connected with a pin [phase] so as to be able to swing from side to side, and the mass-produced [phase] can be attached by bolts to the frame ■ which is a part of the traveling side body ■, using a solution-based method, etc. The front and rear bolts [phase] ■ and the left and right bolts [phase] ■ should be screwed into the four screw holes formed on the front, left, and right sides of the top plate [phase]. [Phase] ○ is inserted through the horizontally long through hole O drilled in the pedestal O and brought into contact with the top surface of the swinging rod [Phase], and the left and right bolts [Phase] @ are the pedestal [Co., Ltd.]
It is placed in contact with the top surface of the

Therefore, the swinging rod [phase] is attached in a diagonally suspended state to the frame ■ of the traveling side body ■ via the swing mounting part O consisting of the pedestal [stock] and the mass production [phase], and the rear polishing roller ■ ■It is designed to land on the top surface of the steel plate.

By screwing and adjusting the front and rear bolts O @ of the swing mounting part O into the screw holes of the mass production [phase], the pin [phase]
By swinging back and forth around the pin and adjusting the left and right bolts [phase] ○ by screwing in, the polishing roller attached to the rear of the swinging rod [phase] swings left and right around the pin [phase]. It is made to land accurately on the top surface of the steel plate■.

In addition, an intermediate roller [phase] is provided at approximately the upper center of the swinging rod [phase], and this is moved up and down by a belt adjustment means [phase], so that a certain level of polishing belt ■ is applied to the intermediate roller [phase]. I'm trying to put some tension on it.

In other words, the intermediate roller [phase] is attached via the arm [phase] to the mounting plate ■ installed upright on the top surface of the swinging rod [phase], while the handle 0
A column [phase] equipped with a screw shaft [phase] is erected,
The screw shaft [phase] is screwed into the arm [phase] so that the arm [phase] is swung up and down, and the position of the intermediate roller [phase] attached to the arm [phase] is adjusted. There is.

Furthermore, at the rear of the swinging rod [phase], an auxiliary wheel [phase] that can be moved up and down by the bundle ■ is provided near the bearing [phase], and on the upper surface of the rear part of the swinging rod [phase], there is a auxiliary wheel [phase] that can be moved up and down during polishing.
[phase] A holding means [phase] for holding the rear part is provided.

The holding means @ shown as an example is such that a regulating rod @ with a hook @ formed at its tip is rotatably attached to a fixed rod @ extending from the traveling side body part ■ with a pin @.
is engaged with the rear end of the swinging rod [phase].

[Phase] is the belt cover for the abrasive belt ■.

The dust removal device O effectively collects primer dust generated by polishing the steel plate ■, and has a hood with an opening near the front of the front polishing roller ■. A dust collection box @ is placed on the body part (■), and a fan @ is placed above it.

The dust collection box @ may be of any type as long as it can reliably collect high-temperature dust generated by polishing, and may have various internal structures.

Therefore, in the example shown, the dust collection box @ is divided into two sections, the front chamber @ and the rear chamber [phase], and a plurality of baffle plates t-9... are arranged alternately in the front chamber @. In addition, in the rear chamber [phase] there is a filter in which relatively coarse metal chips such as stainless steel and metal coil pieces are filled in a wire mesh of a certain shape. Relatively fine-mesh filters, such as thin coiled metal wires like scrubbing brushes, laid flat in a wire mesh.
Furthermore, as finer filters, filters in which a fire-resistant and heat-resistant material such as glass wool is filled in a flat plate between nylon nets are sequentially arranged in a plurality of stages.

(2) is a duct that connects the hood [with] and the front chamber of the dust collection box (2), and (2) is an arm that stands on the traveling side body (2) and is attached to the fan (2).

The configuration of the present invention is as described above. When polishing the top surface of a steel plate ■, the running side body part ■ is placed on the steel plate ■, and the polishing roller ■ and the polishing belt ■ of the polishing section [F] are Adjust the position so that it contacts the surface accurately.

That is, first, in order to bring the guide roller ■■ in the guide means @ on one side of the traveling body part ■ into contact with the vertical end surface ■ of the steel plate C,
Alternately rotate the levers ■ of the body lifting device ■ to make the rotating wheels [phase] land on the steel plate and move the front or rear wheels ■■
The guide roller (2) is brought into contact with the vertical end surface (2) of the steel plate by the operator alternately pushing the front side and the rear side of the traveling side body (2).

In addition, when the guide means 00 is provided on both sides of the running side body part ■, the guide rollers on the opposite side ■■ are the vertical end faces of the steel plate ■■
It is not necessarily necessary to make it contact with the vertical end surface (2), but it is sufficient to place it at a certain distance to the side of the vertical end surface (2).

Once the positioning of the traveling side body part (■) is completed as described above, the next step is to screw the four bolts [phase] O [phase] O of the swing mounting part O in order to position the polishing roller ■ of the polishing part ■. Turn on and swing the swinging rod back and forth and left and right so that the abrasive belt ■ is accurately positioned on the top surface of the steel plate with appropriate contact pressure.

In other words, mass production of the front and rear bolts [phase] ■ in the swing mounting part O [
Screw it into the threaded hole of the left and right bolts [phase] and place the bolt tip in contact with the top surface of the swinging rod [phase] to adjust the back and forth swing around the pin [phase]. [Co., Ltd.] The polishing belt ■ stretched over the polishing roller ■ at the rear of the swinging rod [phase] is accurately placed in front of the steel plate ■ by touching it upward and adjusting the left and right swinging around the pin [phase]. Bring it into contact.

Also, turn the bundle @ at the rear of the swinging rod [phase] to make the auxiliary wheel [phase] land on the upper surface of the steel plate ■, and at the same time, attach the end hook @ of the regulating rod @ in the holding means @ to the swinging rod [phase]
It is engaged with the rear end to prevent the swinging rod [phase] from shifting or rattling during polishing.

Once the position adjustment and fixation of the swinging rod [phase] is completed as described above, the polishing belt ■■ in the polishing parts ■■ on both sides of the traveling side body ■■ will be accurately applied to the upper surface of the steel plate ■ with appropriate pressure. At this point, if the polishing morph 0 [phase] is rotated, the polishing belt ■■ becomes endless between the polishing roller ■■ and the intermediate roller [phase] as shown by the arrow [phase] in Fig. 2.5. rotate to
Polishing is performed at the contact point between the polishing belt ■ and the upper surface of the steel plate in the rear polishing row 90 portion, and at the same time, the traveling side body portion ■ is run at a constant and gentle speed as shown by the arrow [phase] in Figures 1 and 2. As a result, the polishing is performed linearly and uniformly over the upper surface of the steel plate.

At this time, the rear part of the swinging rod to which the polishing roller ■ is attached is subjected to the most intense vibration due to the rotation of the roller ■.
The swinging rod [phase] is pushed backward by the frictional force of the abrasive belt ■ part of the roller ■, but it maintains an accurate position because the rear end position is regulated by the regulating rod @ of the holding means @. Furthermore, since there is an auxiliary wheel (phase) at the rear of the swinging rod (phase), the position is stable and polishing can be performed smoothly.

In addition, the traveling body part (■) runs in a direction slightly diagonal to the longitudinal direction of the steel plate (■), but one of the guide rollers (■■) provided at the front and back of both sides of the traveling body part (■) runs against the end surface of the steel plate. The traveling frame part (2) is restricted to travel at a fixed position on the steel plate (2) by coming into contact with the steel plate (2).

In addition, the guide roller ■■ on the other side is located near the end face of the steel plate and does not come into direct contact with the end face, but when the traveling frame part ■ runs backwards after traveling a certain distance, the guide roller ■■ comes into contact with the end face. As a result, the traveling frame part (2) is regulated so that it travels in a fixed position even when traveling in reverse.

Therefore, if necessary, the polishing part can also be used when driving backwards.
It is also possible to operate the machine for repeated polishing.

On the other hand, in the dust removal device O, the fan @ also operates, and the primer dust peeled off from the steel plate (■) by the polishing is sucked through the opening @ of the hood [phase], passes through the duct @, and enters the dust collection box @. In the front chamber of the dust collection box, relatively large dust particles are removed by the baffle plate ◎..., and other dust particles are collected as they pass through multiple stages of filters with finely milled mills. It is.

As described above, the steel plate automatic polishing device of the present invention automatically and continuously polishes the welded portion of the steel plate using an abrasive belt, uniformly removing primers adhering to the steel plate, and ensuring good welding. By adjusting the position of the swinging rod [phase] in the polishing section ■ using the swing attachment section 01 holding means@, the polishing belt ■ can be accurately applied to the upper surface of the steel plate to be polished with appropriate pressure. This makes it possible to perform uniform and good polishing.

In addition, as shown in the example, if the polishing section (2) is arranged on both sides of the traveling body part (2), two surfaces of the steel plate can be simultaneously polished by running one traveling body part (2), which is extremely efficient. Good.

Furthermore, since a dust removal device O is installed in the traveling body part ■, the dust generated during polishing is effectively collected using a multi-stage filter without being scattered elsewhere, and the surrounding air environment can be maintained in a good condition. can.
