Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, in particular to a welding equipment for a garbage truck loader. Background Art

[0002] In recent years, with the development of waste disposal technology, garbage trucks have emerged. These highly mechanized trucks can promptly collect and clear the massive amounts of garbage generated daily in modern cities, alleviating the urban waste problem and therefore playing a vital role in modern waste management. A garbage truck is a highly coordinated vehicle with a structure, hydraulics, and electrical controls. It is primarily used to collect and transport various types of garbage. It compresses and crushes the loaded garbage, increasing its density and reducing its volume, greatly improving the efficiency of garbage collection and transportation. As a key component of garbage loading operations, the loader transfers the garbage into the truck's compartment.

[0003] When transferring garbage into the garbage truck body, the filler rotates to contact the ground, and the garbage to be collected is filled into the filler. Then the filler resets and transfers the garbage into the garbage truck body. The filler frequently collides with the ground during long-term use and transfers heavy garbage, which can easily cause its structure to deform and cause damage. Therefore, in order to strengthen the structural strength of the filler and extend its service life, reinforcement ribs are usually welded on the bottom of the filler. The welding operation of the filler reinforcement ribs usually needs to be performed on professional welding equipment.

[0004] The existing welding equipment for garbage truck loaders has gradually exposed its shortcomings during use, mainly in the following aspects:

[0005] First, there is the problem of inconvenience in clamping and positioning the filler and the reinforcement. Specifically, the structure of the filler is relatively unique, and a single clamping method cannot effectively clamp the filler. Therefore, the filler is prone to displacement during welding, affecting the welding of the reinforcement. Secondly, the reinforcement needs to be welded to the filler, so the structure of the reinforcement is also relatively unique. During welding, the welder needs to accurately measure the welding position and mark it, and then hold the corresponding reinforcement and fit it to the marked position of the filler for welding. Therefore, the clamping and positioning process of the reinforcement are inconvenient to operate.

[0006] Second, there is the problem of poor continuous processability. Specifically, the reinforcing ribs are divided into horizontal ribs and vertical ribs. When welding several horizontal ribs and vertical ribs, it is necessary to repeat the welding operations mentioned in the first problem point. The reciprocating measurement and marking operations and positioning and fitting operations will lead to the interruption of the welding process, which in turn leads to poor continuous processability.

[0007] Third, there is the problem of low degree of welding automation. Specifically, due to the influence of the filler and the structure of the reinforcement itself, the welding trajectory of the welding gun when welding the reinforcement is also relatively specific. Therefore, the existing welding equipment cannot automatically weld the reinforcement and can only be welded by manual welding. As a result, the degree of welding automation is low. The manual welding method also has the problems of low welding efficiency and low welding accuracy.

[0008] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Summary of the Invention

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. When clamping and positioning the filler, use the lifting device to lift the filler onto the roller. The telescopic end of the hydraulic telescopic cylinder contracts, thereby driving the positioning shaft and the upper positioning plate to move closer to the filler until the two positioning shafts are respectively inserted into the two hinge holes on the filler. The telescopic end of the lifting telescopic cylinder contracts, and the lifting L-shaped plate, side baffles and positioning shafts move downward. With the cooperation of the roller, the filler rotates until the top of the filler contacts the upper positioning plate. The telescopic end of the translation telescopic cylinder extends, thereby driving the side baffles to move closer to the filler until the two positioning shafts are respectively inserted into the two hinge holes on the filler. The side baffles contact the two ends of the loader accordingly, the telescopic end of the electric telescopic cylinder extends, and the lower positioning plate moves toward the loader until it contacts the inclined surface at the bottom of the loader, thus completing the clamping and positioning of the loader. When clamping the horizontal ribs, place the horizontal ribs on the horizontal rib support bottom plate, and the two telescopic ends of the first two-way telescopic cylinder contract until the two horizontal rib clamping plates clamp the horizontal ribs. Similarly, when clamping the vertical ribs, place the vertical ribs on the vertical rib support bottom plate, and the two telescopic ends of the second two-way telescopic cylinder contract until the two vertical rib clamping plates clamp the vertical ribs. When the transverse reinforcement to be welded is positioned with the filler, the telescopic end of the lifting and telescopic cylinder is extended, thereby driving the filler to rise, and the servo motor drives the lower single-tooth screw to rotate, thereby driving the movable plate to slide horizontally until the movable plate slides to the first preset position. At this time, the filler is located above the clamped transverse reinforcement, and the telescopic end of the lifting and telescopic cylinder is retracted, and the filler is lowered until the bottom of the filler is in contact with the top of the transverse reinforcement. At this point, the positioning of the transverse reinforcement and the filler is completed. After the transverse reinforcement and the filler are welded, the telescopic end of the lifting and telescopic cylinder is extended again to drive the filler to rise, and the servo motor drives the filler again. The movable plate slides horizontally until it slides to the second preset position. At this time, the filler is located above the clamped vertical rib, and the telescopic end of the lifting and telescopic cylinder contracts, and the filler descends until the bottom of the filler is in contact with the top of the vertical rib. At this point, the positioning of the vertical rib and the filler is completed. The device can quickly clamp the filler and the required transverse and vertical ribs, and has high clamping stability. When welding the transverse or vertical ribs, the transverse or vertical ribs can be quickly positioned and fitted with the corresponding welding position of the bottom of the filler, thereby improving the convenience of the clamping and positioning operation of the filler, transverse and vertical ribs.

[0031] 2. When welding the transverse reinforcement, the driving motor drives the first single-thread screw to rotate, and then drives the sliding plate to slide horizontally. With the cooperation of the lifting plate and the guide column, the driven plate starts to move. The motion trajectory of the driven plate is the same as the shape of the guide groove. Driven by the driven plate, the T-shaped seat and the automatic welding gun for the transverse reinforcement move. During the movement, the nozzle of the automatic welding gun for the transverse reinforcement automatically welds the position where the transverse reinforcement and the filler fit together. Similarly, when welding the vertical reinforcement, the control motor drives the second single-thread screw to rotate, and then drives the sliding block, the lifting seat and the automatic welding gun for the vertical reinforcement to move. The vertical reinforcement automatically The welding gun welds one of the vertical bars during its movement. After the welding of the vertical bar is completed, the telescopic end of the telescopic cylinder is controlled to retract, thereby driving the vertical bar automatic welding gun to descend and avoid the horizontal bar that has been welded. The sliding block slides horizontally until the vertical bar automatic welding gun moves to the area where the next vertical bar is located. The telescopic end of the telescopic cylinder is controlled to reset, and the sliding block drives the vertical bar automatic welding gun to move, and then weld the next vertical bar. The above welding process is repeated until all the vertical bars are welded. The equipment can weld the horizontal and vertical bars to the filler at one time, so it has good continuous processability.

[0032] 3. The equipment has a high degree of automation. During use, it can not only automatically clamp and position the filler, horizontal reinforcement and vertical reinforcement, but also automatically weld the horizontal reinforcement and vertical reinforcement with fast welding speed and high welding accuracy.

[0063] The working principle of this device is:

[0064] When clamping and positioning the filler 3, use a lifting device to lift the filler 3 onto the roller 23 (such as Figure 1As shown in FIG5 ), the telescopic end of the hydraulic telescopic cylinder 20 contracts, thereby driving the positioning shaft 21 and the upper positioning plate 8 to move toward the filler 3, until the two positioning shafts 21 are respectively inserted into the two hinge holes on the filler 3, the telescopic end of the lifting and telescopic cylinder 16 contracts, the lifting L-shaped plate 15, the side baffle 13 and the positioning shaft 21 move downward, and with the cooperation of the roller 23, the filler 3 rotates until the top of the filler 3 abuts against the upper positioning plate 8 (as shown in FIG5 ). Figure 2 As shown in the figure, the telescopic end of the translation telescopic cylinder 14 is extended, thereby driving the side baffles 13 to move in the direction close to the filler 3, until the two side baffles 13 contact the two ends of the filler 3, the telescopic end of the electric telescopic cylinder 10 is extended, and the lower positioning plate 11 moves in the direction close to the filler 3, until it abuts against the inclined surface at the bottom of the filler 3, thus completing the clamping and positioning of the filler 3. When clamping the transverse rib 38, the transverse rib 38 is placed on the transverse rib support bottom plate 39, and the two telescopic ends of the first bidirectional telescopic cylinder 41 are retracted until The two horizontal rib clamping plates 40 clamp the horizontal rib 38. Similarly, when clamping the vertical rib 46, the vertical rib 46 is placed on the vertical rib support base plate 48. The two telescopic ends of the second two-way telescopic cylinder 55 are retracted until the two vertical rib clamping plates 47 clamp the vertical rib 46. When the horizontal rib 38 to be welded is positioned with the filler 3, the telescopic end of the lifting telescopic cylinder 16 is extended, thereby driving the filler 3 to rise. The servo motor 19 drives the lower single-tooth screw 6 to rotate, thereby driving the movable plate 17 to slide horizontally until the movable plate 17 slides to the first preset position. The loader 3 is positioned above the clamped transverse rib 38. The telescopic end of the lifting and telescopic cylinder 16 contracts, and the loader 3 descends until the bottom of the loader 3 is in contact with the top of the transverse rib 38. The positioning of the transverse rib 38 and the loader 3 is completed. After the transverse rib 38 and the loader 3 are welded, the telescopic end of the lifting and telescopic cylinder 16 is extended again and drives the loader 3 to rise. The servo motor 19 drives the movable plate 17 to slide horizontally again until the movable plate 17 slides to the second preset position. At this time, the loader 3 is located on the clamped vertical rib 46. On the other hand, the telescopic end of the lifting and telescopic cylinder 16 is retracted, and the filler 3 is lowered until the bottom of the filler 3 is in contact with the top of the vertical rib 46, thereby completing the positioning of the vertical rib 46 and the filler 3. The device can quickly clamp the filler 3 and the required transverse ribs 38 and vertical ribs 46, and has high clamping stability. When welding the transverse ribs 38 or vertical ribs 46, the transverse ribs 38 or vertical ribs 46 can be quickly positioned and fitted with the corresponding welding positions on the bottom of the filler 3, thereby improving the convenience of the clamping and positioning operation of the filler 3, the transverse ribs 38 and the vertical ribs 46.

[0065] When welding the transverse rib 38, the driving motor 27 drives the first single-thread screw 25 to rotate, thereby driving the sliding plate 28 to slide horizontally. With the cooperation of the lifting plate 24 and the guide column 36, the driven plate 29 starts to move. The motion trajectory of the driven plate 29 is the same as the shape of the guide groove 35. Driven by the driven plate 29, the T-shaped seat 31 and the transverse rib automatic welding gun 32 move. During the movement, the nozzle of the transverse rib automatic welding gun 32 automatically welds the position where the transverse rib 38 and the filler 3 are fitted. Similarly, when welding the vertical rib 46, the control motor 50 drives the second single-thread screw 43 to rotate, thereby driving the sliding block 53, the lifting seat 52 and the vertical rib automatic welding gun 44 to move. The rib automatic welding gun 44 welds one of the vertical ribs 46 during the movement. After the welding of the vertical rib 46 is completed, the telescopic end of the telescopic cylinder 54 is controlled to retract, thereby driving the vertical rib automatic welding gun 44 to descend and avoid the welded transverse rib 38. The sliding block 53 slides horizontally until the vertical rib automatic welding gun 44 moves to the area where the next vertical rib 46 is located. The telescopic end of the telescopic cylinder 54 is controlled to reset, and the sliding block 53 drives the vertical rib automatic welding gun 44 to move, thereby welding the next vertical rib 46. The above welding process is repeated until all the vertical ribs 46 are welded. The equipment can weld the transverse rib 38 and the vertical rib 46 to the filler 3 at one time, so the continuous processability is good.

[0066] The equipment has a high degree of automation. During use, it can not only automatically clamp and position the filler 3, the transverse ribs 38 and the vertical ribs 46, but also automatically weld the transverse ribs 38 and the vertical ribs 46 with high welding speed and precision.
