DETAILED DESCRIPTION

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] As shown in Figure 1 , Figure 2 , a welding method for a skirt plate of an escalator uses a welding system for producing a skirt plate of an escalator, which includes a workbench 1, a feeding box 2, a transmission frame 3, a transmission plate 4, a welding manipulator 5, and a discharging groove 6.

[0030] As shown in Figure 1 , Figure 2 , Figure 3 , the workbench 1 is horizontally arranged on the ground, and the feeding box 2 is arranged in multiple numbers, which are arranged side by side below the starting end position of the workbench 1, and the feeding port 11 is arranged through the workbench 1 to communicate with the upper end of the feeding box 2.

[0031] As shown in Figure 2 , Figure 3 , Figure 4 , the transmission frame 3 is arranged across the workbench 1 and is slidingly connected to the two sides of the workbench 1. The transmission plate 4 is horizontally arranged on the transmission frame 3 and is attached to the workbench 1. The transmission groove 41 for embedding the steel plate is arranged through the lower end surface of the transmission plate 4 in a transverse direction, and the pneumatic suction cup 42 for adsorbing the steel plate is embedded in the top wall of the transmission groove 41.

[0032] As shown in Figure 2 , Figure 3 , the welding manipulator 5 is arranged at the tail end position of the workbench 1 and is used for welding operation between adjacent steel plates. The discharging groove 6 is arranged obliquely below the workbench 1 and is located in front of the welding manipulator 5.

[0033] As Figure 2 , Figure 3 shown, a pair of welding interfaces 12 are provided on the workbench 1, and the connection positions of adjacent steel plates are located above the welding interfaces 12. The lower end surface of the workbench 1 is provided with a collection box 13 located below the welding interfaces 12.

[0034] As Figure 2 , Figure 3 shown, the workbench 1 is provided with clamping blocks 7 on both sides, which are located in front of the discharge chute 6 and are used to clamp the most two end steel plates. The workbench 1 is provided with a double-headed cylinder 71 for controlling the two clamping blocks 7 to move closer or farther away from each other.

[0035] When welding work needs to be performed on the escalator skirt plate, the transmission frame 3 is controlled to drive the transmission plate 4 to slide to the starting end position of the workbench 1, so that the transmission plate 4 is located directly above the feeding port 11 on the workbench 1. Then each feeding box 2 pushes the stacked steel plates inside upward, so that the uppermost steel plate passes through the feeding port 11 on the workbench 1 and is embedded in the transmission groove 41 on the transmission plate 4, and the lower end surface of the steel plate is flush with the upper end surface of the workbench 1.

[0036] Then the pneumatic suction cup 42 on the top wall of the transmission groove 41 is controlled to move downward to adsorb the steel plate in the transmission groove 41, and then the pneumatic suction cup 42 is used to control the steel plate to move upward, so that the lower end surface of the steel plate is higher than the surface of the workbench 1. Then the transmission frame 3 is used to continue to drive the transmission plate 4 to slide backward, and the transmission plate 4 drives multiple steel plates to slide backward synchronously.

[0037] Until the adjacent steel plates move to the welding interface 12 position on the workbench 1, the pneumatic suction cup 42 is used to control the steel plate to move downward and place the steel plate on the workbench 1, and the pneumatic suction cup 42 is separated from the steel plate. Then the double-headed cylinder 71 is used to drive a pair of clamping blocks 7 to move closer to each other, so that the clamping blocks 7 push the two end steel plates to move closer to the middle, so that the end positions of multiple steel plates contact each other.

[0038] Then the pneumatic suction cup 42 is controlled to move downward again, so that the pneumatic suction cup 42 presses the steel plate, and the clamping blocks 7 release the steel plate. Then the welding manipulator 5 is used to weld and fix the connection position of the steel plate, and the welding slag can fall into the collection box 13 for automatic collection.

[0039] When the steel plate is welded, the pneumatic suction cup 42 is used to control the steel plate to move upward, and then the transmission frame 3 is used to continue to drive the transmission plate 4 to slide backward, and the transmission plate 4 drives multiple steel plates to slide backward synchronously. Until the steel plate slides to the discharge chute 6 position, the pneumatic suction cup 42 is separated from the steel plate, and the steel plate automatically slides into the discharge chute 6 to complete the automatic discharge of the welded skirt plate.

[0040] Therefore, by setting a high-automation welding system, automatic feeding, transmission, welding and unloading of the steel plate are realized, automatic welding of the escalator skirt plate is completed, and welding efficiency is improved.

[0041] As shown in Figure 2 , Figure 5 , the feeding box 2 comprises a box body 21, a supporting plate 22, a hydraulic jack 23 and a driving mechanism 8. The box body 21 is provided with an open upper end, and is provided with universal wheels 24 at the lower end. The supporting plate 22 is horizontally arranged in the box body 21 and is vertically slidably connected to the box body 21.

[0042] As shown in Figure 2 , Figure 5 , the hydraulic jack 23 is arranged at the bottom wall of the box body 21 and below the supporting plate 22, and is used for controlling the vertical sliding of the supporting plate 22. The handle 25 of the hydraulic jack 23 penetrates the box body 21, and the driving mechanism 8 is used for controlling the turning of the handle 25.

[0043] As shown in Figure 2 , Figure 5 , the driving mechanism 8 comprises a driving cylinder 81, a clamp 82 and a locking pin 83. The lower end of the driving cylinder 81 is rotatably connected to the workbench 1, the clamp 82 is arranged on the piston rod of the driving cylinder 81 and is used for clamping the handle 25. The locking pin 83 penetrates the handle 25, and the handle 25 is rotatably connected to the locking pin 83.

[0044] As shown in Figure 2 , Figure 5 , a circle of sliding plates 26 is arranged on the outer wall of the upper end of the box body 21, the workbench 1 is provided with guide rails 14 on both sides of the feeding opening 11 at the lower end face, and the end position of the sliding plate 26 is provided with a plug rod 27 inserted into the lower end face of the workbench 1.

[0045] When the steel plate needs to be fed, the steel plate is placed in the box body 21 and is supported by the supporting plate 22. Then the box body 21 is controlled to move below the workbench 1, and the box body 21 is pushed to move horizontally, so that the sliding plate 26 on the box body 21 slides into the guide rail 14 at the lower end face of the workbench 1. Then the plug rod 27 is inserted into the workbench 1, so that each box body 21 is installed and fixed.

[0046] Then the driving cylinder 81 is controlled to turn over, so that the clamp 82 at the front end of the driving cylinder 81 clamps the handle 25 of the jack, and then the locking pin 83 penetrates the clamp 82 and the handle 25, so that the connection and fixation between the driving cylinder 81 and the handle 25 are realized. Then the driving cylinder 81 is controlled to stretch and retract, and under the action of the two end rotating connections, the handle 25 is controlled to swing back and forth, so that the hydraulic jack 23 is pressurized downward, and the supporting plate 22 is controlled to rise intermittently, so that the automatic feeding and continuous and stable feeding of the steel plate are realized, and the efficient welding of the escalator skirt plate is ensured.

[0047] The specific embodiments are only an explanation of the present application, and are not a limitation of the present application, and the person skilled in the art can make modifications to the embodiments without creative contribution according to the needs after reading the specification, but as long as the modifications are within the scope of the claims of the present application, they are protected by the patent law.
