Description

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 a device that automatically polishes the welded parts of steel plates used in steel structures to uniformly remove primers adhering to the steel plates and to ensure good welding.

Conventionally, polishing of the welded parts of the steel plate was carried out manually using a polishing roller, but this not only made the work inefficient, but also made it difficult for the worker to perform the polishing. There was a problem in efficiently and uniformly removing primers and other stains that adhered to the steel plate after uneven paper cutting.The present invention solves the above problem by removing the primers and other stains that adhere to the steel plate at a constant speed. A polishing section with an abrasive belt driven by a motor is attached to the running part that runs slowly on the road, and the top surface of the steel plate is automatically polished uniformly, and the primer dust that has been peeled off and removed by the abrasive belt is also removed. The dust is collected by a dust removal device installed on the side body.

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.・
The traveling side body part ■ is arranged so that it runs straight and slightly diagonally over the steel plate ■ at a constant speed by a traveling motor; A polishing section ■ which polishes the upper surface of the steel plate ■ with a polishing belt ■ attached to two polishing rows ■■; It consists of a dust removal device O that collects dust.

That is, the traveling body part (■) has the four wheels (■) described above at its lower part, is driven by an internally built-in motor (not shown), and is placed on the steel plate (■) to be polished. The vehicle travels straight or slightly diagonally on a steel plate, and the motor for travel is equipped with a clutch, and the clutch is turned on and off by a clutch per [phase] installed on the side along the traveling side body @. That's what I do.

Further, on one or both sides of the running side body part (2), a guide means (2) is provided with a guide column (e) having a guide roller (6i1) at its lower end that rotates horizontally in contact with the side end surface of the steel plate (2). If necessary, the guide columns 206 are slidably extended and contracted in the direction of lateral force so that the distance between the guide rows 206 can be adjusted according to the width of the steel plate.

Furthermore, #i is provided at the lower center of the front and rear sides of the traveling side body section (■), respectively. The rotating wheel ■ installed perpendicular to the lower part of the box and the wheel ■ is designed to move up and down. That is, the fixing box (■) is fixed to the travel control unit [Co., Ltd.], and the L-shaped operating lever (0) is inserted laterally, and a cam (not shown) is inserted into the box (■) and the lever (■) is inserted outwardly. A structure in which a plate (not shown) that rotates about one point and returns to rotation by the force of a spring is provided in the box (2), and a rotating ring [phase] is attached to the bottom surface of the plate. By doing so, when the operating lever (■) is rotated, the cam rotates together with the lever (■) and presses the plate downward, and the plate, which holds the rotating wheel (■), is rotated by a certain angle against the force of the spring button. Then, the rotary wheel [F] is firmly landed on the copper plate (2), so that the front or rear wheel (2) floats up. Note that this is the operation panel installed at the rear of the traveling side body.

On the other hand, one side or both sides of the polishing part @ traveling side body ■ KIIk
Therefore, in the example shown in the figure, the polishing section [F] is arranged on both sides of the traveling drive section. This is what I did. In other words, # part is polished on the front part of the O side of the traveling body part ■!
A rear polishing row 2■ was provided at the rear of the side surface, and an intermediate roller ■ was placed on both polishing rollers. It is a #s polished low-grade steel plate ■ placed at a certain distance above the top surface so that it does not come in contact with the top surface, and a 1M
The rear polishing roller ■ is directly connected to the polishing motor @ which is mounted on the running side body ■. ]
The polishing roller is attached to the rear part of the steel plate (1) via a bearing part, and the upper surface of the steel plate (1) is polished at the rear polishing roller part. In addition, the motor [phase] is directly connected to the front polishing roller.
'i In the embodiment, it is provided separately from the swinging rod [phase], but it can also be provided integrally.

Attachment of the swinging rod [phase] to the traveling side body ^ The swinging rod 0 is attached to the traveling driving/disengaging part through the swinging attachment part @ provided near the upper part of the front part of the swinging rod 0, and thereby the swinging Motion rod [Co., Ltd.] Keg attachment part 0
The swinging rod [
It is possible to adjust the position II of the rear polishing roller [phase] attached to the steel plate [phase] with respect to the upper surface of the steel plate.

In other words, the swinging mounting part is made up of two overturned plates and one upper plate, and the pedestal is shaped like a mouth, and a pin inserted through the lower part of the side plate is used to attach the swinging rod. [Phase] Upper surface K liJ vI
The upper plate of the pedestal [phase] has two oblong holes O in the front and back, and two standing plates are installed at the front edge of the upper surface of the pedestal [phase]. is erected, and a mass production [stock] which is roughly shaped like a side plate @ life and an upper plate [stock] is placed on the standing board @@ in the same way as the pedestal [phase], and the side plate of the mass production [stock] is placed. @
and the above-mentioned standing plate [phase] are connected with a pin [phase] so as to be able to swing from side to side, and the mass production [stock] is mounted by bolting, welding, etc. It shall be fixed and installed by appropriate means, and the front and rear bolts [phase] [phase] and the left and right bolts 0 [yes] are screwed into the 94 screw holes formed on the front, rear, left and right sides of the upper plate [stock], and Push the front and rear bolts Φσψ through the nine-pronged horizontally elongated holes e in the pedestal @, and attach the swinging rod [phase]
The left and right bolts [with] are placed in contact with the top surface of the pedestal [
It is placed in contact with the top surface of the phase.

Therefore, the frame [phase] of the traveling body part ■ is connected to the swinging mounting part [phase] consisting of the swinging rod pedestal [phase] and the mass production [phase].
The rear polishing roller [Co., Ltd.] is installed diagonally suspended on the
The shape is such that it lands on the top surface of the steel plate ■. Therefore, when adjusting the front and rear bolts @ [phase] of the swing mounting part @ by screwing them into the screw holes of the mass production [stock], it will swing back and forth around the bottle @, and the left and right bolts @ [phase] will be adjusted. When adjusted by screwing in, the swinging rod [
The polishing roller [phase] attached to the rear of the copper plate [phase] is made to land on the upper surface of the copper plate ■.

In addition, an intermediate roller [Co., Ltd.] is installed approximately at the upper center of the swinging rod, and this is moved up and down by a belt adjustment means [Phase] to apply a constant tension to the abrasive belt ■ that has been subjected to K*R. I try to put it on. In other words, the intermediate roller @ is attached via an arm to a mounting plate @ erected on the upper surface of the swinging rod, and - in the unlikely event that a post [stock] is attached to a screw shaft [stock] provided with a handle. Stand it upright and attach the screw shaft [stock] to the arm@
The arm [phase] is screwed into and associated with the roller so as to swing up and down to adjust the position of the intermediate roller attached to the arm.

At the rear of the oscillating rod [phase], an auxiliary wheel [phase] that can move up and down from the handle OK is installed near the shaft 9@, and when polishing the rear upper surface of the oscillating rod [phase], the 1m17 rod [phase]
A holding means is provided to hold the rear part.

The holding means shown in one embodiment is such that a regulating rod with a hook formed at its tip is rotatably attached to a fixed rod extending from the traveling body part [Co., Ltd.] with pin 0. It is designed so that @ engages with the rear end of the swinging rod [phase]. This is the belt cover for the @ke abrasive belt■.

Dust removal device This is a device that effectively collects primer dust generated by polishing the steel plate ■.A hood ψ with an opening is placed close to the front of the front polishing roller ■, and a traveling roller is installed. It is a good idea to place the dust collection box O on top of the part (2) and place the fan on top of it.

High-temperature dust generated by polishing the dust collection box 011*
Any type of material that can be used to collect materials may be used, and various types of internal structures can be used. Therefore, the Monoke dust collector pocket shown as an example was divided into two sections, a front chamber and a rear chamber, and a plurality of puffful plates were alternately arranged in the front chamber. It is assumed that the rear chamber ΦKFi is relatively relatively small, starting with a filter in which metal chips such as stainless steel or metal coil pieces are filled in a wire mesh of a certain shape, and a wire coil as thin as a stainless steel scrubbing brush. 9. A relatively fine-mesh filter, such as by laying metal wire shaped like a metal wire flat in a wire mesh. 5! - As a finer filter, there is a fireproof filter like a glass cooler between the nylon nets.
Filters filled with a heat-resistant material in the form of a flat plate are sequentially arranged in multiple stages.・This is a duct that connects the hood and the front chamber of the dust collection box O, and ・ is an arm that stands on the traveling body part (■) and has a fan attached to it.

The structure of the present invention is as described above, and when polishing the upper surface of a steel plate (■), the sliding member part is placed on the steel plate (2), and the polishing roller [phase] of the polishing part (2) and the polishing belt (3) are placed on the steel plate (2). Adjust the position so that it accurately contacts the surface to be polished. That is, first, in order to bring the guide roller (■■) in the guide means (@) on the − side of the traveling body part [Co., Ltd.] into contact with the vertical end surface of the steel plate (■),
Alternately rotate the levers ■ of the body lifting device ■ to make the rotating shaft [phase] land on the steel plate ■■1 and move the front or rear wheels■■
, and the operator alternately presses the front side and rear side (!-) of the traveling body part @0 so that the guide roller ■ comes into contact with the vertical end surface eK of the steel plate. In addition, if the guide means ■01 are provided on both sides of the traveling support section [Co., Ltd.], it is not necessary that the guide rollers ■■01 on the opposite side come into contact with the vertical end face of the steel plate ■■, but at a certain distance. It is only necessary to position it on the side of the vertical end surface O.

After completing the positioning of the traveling drive and cutting part as described above, the next step is to position the polishing roller of the K1FF polishing part.
Screw in and swing the swinging rod back and forth and left and right to ensure that the abrasive belt ■ is accurately positioned on the upper surface of the steel plate ■ with appropriate contact pressure. In other words, screw the front and rear bolt 0 [phase] in the swing mounting part 0 into the screw hole of the mass production [phase], bring the bolt tip into contact with the top surface of the swing rod, and adjust the swing back and forth around the pin. Screw in the bolt o [phase] and bring its tip into contact with the top surface of the pedestal [phase], adjust the left and right swinging around the bottle @, and attach the polishing belt to the polishing roller at the rear of the swinging rod [phase]■ accurately contact the front of the steel plate ■.

-! At the rear of the nine swinging rods, turn the handle fully to press the auxiliary wheels onto the upper surface of the steel plate. At the same time, place the tip hook O of the regulating rod O in the holding means @ button on the rear end of the swinging rod. This is to prevent the swinging rod [phase] from shifting or rattling during polishing.

Once the position adjustment and fixing of the swinging rod is completed as described above, the polishing belts ■■ in the polishing parts ■■ on both sides of the traveling body part will be accurately applied to the upper surface of the steel plate ■ with appropriate pressure. If the polishing motor 0 [phase] is rotated at this point, the polishing belt ■■ will move between the polishing roller ■ [phase] and the intermediate roller [phase] as shown by the arrow in Figure 2.5. rotates endlessly,
Polishing is carried out at the contact point between the polishing belt ■ and the upper surface of the steel plate in the rear polishing row 20 section, and at the same time the traveling body part [Co., Ltd.] is run at a constant and gentle speed as shown by the arrows in Figures 1 and 2. As a result, the polishing is performed linearly and uniformly along 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 severe vibration due to the rotation of the roller, and the frictional force of the polishing belt 9 on the rollers causes the swinging rod to move backward. However, since the far end position is regulated by the regulating rod @ of the holding means @, the accurate position M
Furthermore, since there is an auxiliary wheel (phase) at the rear of the swinging rod (phase), it is positionally stable and polishing can be performed smoothly.

In addition, the traveling body part [Co., Ltd.] runs in a direction slightly diagonal to the longitudinal direction of the steel plate ■, but one of the guide rollers ■e provided at the front and back of both sides of the traveling body part ■
(2) comes into contact with the end face of the steel plate and restricts the running drive part (2) to travel at a predetermined position on the steel plate (2). The guide roller on the Marano side is located close to the end face of the steel plate and does not come into direct contact with the end face. The QG comes into contact with the end face, thereby restricting the traveling body part to travel at a fixed position even during pack traveling. Therefore, if necessary, operate the polishing part ■■ even when driving backwards,
You can also do repeated polishing.

On the other hand, in the dust remover O, the fan operates, and the primer dust peeled off from the steel plate (■) by the polishing is sucked through the opening of the hood @, passes through the duct e, and enters the dust collection box @9. In the front chamber of the dust collection box O, dust that is relatively larger than the puff full plate O...k is removed, and other dust is sequentially made finer and passes through a multi-stage filter. It will be supplemented.

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. The position of the swinging rod [phase] in the polishing section ■ is adjusted by swinging 1IJI! By using the lX attachment part @ and the holding means O, the polishing belt (2) can accurately contact the upper surface of the steel plate to be polished with an appropriate pressure, and uniform and good polishing can be performed. In addition, as shown in the example, if the polishing section (2) is arranged on both sides of the traveling body part, two surfaces of the steel plate can be simultaneously polished by simply running one traveling body part. It is possible and extremely efficient. In the summer, a dust removal device O is installed in the traveling body ■, so the dust generated during polishing is effectively collected using a multi-stage filter without being scattered elsewhere, and the surrounding air environment is maintained in a good condition. be able to.
