The first gear 13 is driven to rotate by the stepping motor 12, and then the first gear 13 is meshed with the second gear 14. The second gear 14 will drive the rotating cylinder 9 to rotate. While the rotating cylinder 9 rotates, the connecting column 10 will drive the turntable 16 to rotate, and the swing arm 15 will also rotate synchronously. When the welding arm welds the cross bar between the two bridge frame side plates 4, the swing arm 15 can push the cross bar forward to realize the stepping movement operation of the bridge frame side plates 4, and the rotation of the turntable 16 can drive the connecting rod mechanism 6 to operate.

[0019] The connecting rod mechanism 6 includes a turntable 16, which is fixedly mounted on the end of the connecting column 10. A protruding column 17 is installed on the end surface of the turntable 16. A bracket 20 is fixedly mounted on the outer side of the bottom bin. A sleeve 21 is installed on the end of the bracket 20 close to the turntable 16. A light rod 19 is slidably mounted inside the sleeve 21. A connecting ring 18 is sleeved on the outer side of the protruding column 17. The end of the light rod 19 is fixedly connected to the connecting ring 18. The turntable 16 rotates to drive the protruding column 17 to rotate. Under the action of the connecting ring 18, the rotational motion of the turntable 16 is converted into a linear motion of the light rod 19. The other end of the light rod 19 is provided with a connecting frame 22, the inner wall of the equipment bin is penetrated with a path groove 24, a movable block 26 is movably provided inside the equipment bin, a guide rod 25 is penetrated in the middle of the movable block 26, and the end of the guide rod 25 movably penetrates the path groove 24, a connecting rod 23 is connected between one end of the guide rod 25 protruding from the operating frame 2 and the connecting frame 22 through a rotating shaft, and when the light rod 19 reciprocates in a straight line, the connecting rod 23 will drive the guide rod 25 to move up and down along the path groove 24, and the movable block 26 will move synchronously with the guide rod 25.

[0020] The swing mechanism 7 includes a sleeve 29, which is rotatably mounted inside the equipment bin. A first swing plate 30 and a second swing plate 32 are fixedly mounted on the surface of the sleeve 29. When the end of the first swing plate 30 moves upward, the end of the second swing plate 32 moves downward. When the end of the first swing plate 30 moves downward, the end of the second swing plate 32 moves upward. The first swing plate 30 is arranged inside the equipment bin, and the second swing plate 32 is arranged outside the operation frame 2. A movable column 31 is arranged at the end of the first swing plate 30. Two side plates 27 are symmetrically mounted on the surface of the movable block 26 close to the first swing plate 30. The two side plates 27 are respectively arranged on both sides of the first swing plate 30. A sliding groove 28 is opened on the surface of the side plate 27. The surface of the movable column 31 is slidably mounted in the sliding groove 28. The movable column 31 is movably inserted into the interior of the sliding groove 28. When the movable block 26 moves up and down inside the equipment bin, the end of the first swing plate 30 will move synchronously with the movement of the movable block 26.

[0021] A card slot is provided at the end of the second swing plate 32, a baffle plate 33 is fixedly installed on the top of the card slot, an extrusion plate 34 is installed on the bottom of the card slot through a torsion spring, an arc groove 35 is provided on the surface of the extrusion plate 34, a limit frame 36 is installed on the top of the outlet of the lower bin 8, a protruding plate is provided on the surface of the limit frame 36, a through groove 38 is provided on the surface of the protruding plate, a Z-shaped plate 39 is slidably installed inside the through groove 38, two plug-in columns 37 are symmetrically provided on the top of the limit frame 36, the surface of the plug-in column 37 movably passes through the top of the Z-shaped plate 39, and a tension spring is connected between the top of the Z-shaped plate 39 and the plug-in column 37. When the end of the plate 32 moves upward, the baffle 33 can first push the Z-shaped plate 39 upward, so that the outlet of the lower material bin 8 is in an open state, and then the extrusion plate 34 will be squeezed by the bottom end of the lower material bin 8, so that the extrusion plate 34 is in an open state. At this time, the cross bar inside the lower material bin 8 will roll into the slot, and when the end of the second swing plate 32 moves downward, the elastic force of the torsion spring will displace the end of the extrusion plate 34 in the direction of the baffle 33, and the extrusion plate 34 has a squeezing and fixing effect on the cross bar inside the slot. At this moment, the elastic force of the tension spring can reset the Z-shaped plate 39, so that under normal conditions, the outlet of the lower material bin 8 is in a closed state.

[0022] The protruding column 17 and the swing arm 15 are in the same straight line. After the cross bar is welded, the swing arm 15 can push the welded cross bar during the rotation process, thereby realizing the step-by-step movement of the cable tray.

[0023] A plurality of positioning arc grooves are evenly provided on the surface of the bridge side plates 4, and the positioning arc grooves cooperate with the cross bar. When the two ends of the cross bar are respectively engaged in the positioning arc grooves on the surfaces of the two bridge side plates 4, the welding arm on the side of the leg 1 can weld and fix it to complete the welding of the cable bridge.

[0024] Working principle: First, the staff slides the two bridge side plates 4 through the bottom bin and sets them on the surfaces of the two main frames 3, and then drives the first gear 13 to rotate through the stepping motor 12, and the first gear 13 drives the second gear 14 to rotate. At this time, the rotating cylinder 9 will rotate counterclockwise. When the rotating cylinder 9 rotates, the protruding column 17 will also rotate. Under the action of the connecting ring 18, the rotational motion of the turntable 16 is converted into a linear reciprocating motion of the light rod 19. When the protruding column 17 rotates to the front of the turntable 16, the light rod 19 moves forward as a whole, and under the action of the connecting rod 23 , the movable block 26 will move to the bottom of the equipment bin, and the end of the first swing plate 30 will also drop to the lowest position, while the end of the second swing plate 32 will move upward, and the baffle 33 can push the Z-shaped plate 39 upward, so that the outlet of the lower bin 8 is in an open state, and the next step is that the extrusion plate 34 will be squeezed by the bottom end of the lower bin 8, so that the extrusion plate 34 is in an open state, and the cross bar inside the lower bin 8 will roll into the card slot, and when the protruding column 17 rotates to the rear of the turntable 16, the light rod 19 moves backward as a whole, and under the action of the connecting rod 23, the movable block 26 will move to the equipment bin. The top of the storage bin is at the top, and at the same time, the end of the first swing plate 30 will also be lifted, and the end of the second swing plate 32 will move downward, and the elastic force of the torsion spring will displace the end of the extrusion plate 34 in the direction of the baffle plate 33, and the extrusion plate 34 has an extrusion and fixing effect on the cross bar inside the slot, and at this moment the elastic force of the tension spring can reset the Z-shaped plate 39, so that the outlet of the lower bin 8 is in a closed state under normal conditions, and at this moment the end of the second swing plate 32 will be parallel to the two bridge side plates 4, and the two ends of the cross bar inside the slot will be respectively clamped in the positioning arc grooves on the surfaces of the two bridge side plates 4, and the second The downward pressure at the end of the swing plate 32 can position the cross bar to ensure that the cross bar will not shake during the welding process, thereby improving the welding quality. Subsequently, the welding arm on the side of the leg 1 can weld and fix it to complete the welding of the cable tray. Finally, the turntable 16 continues to rotate, and after the cross bar is fixedly welded between the two bridge side plates 4, the end of the second swing rod 32 moves upward. At this time, the cross bar directly above the rotating cylinder 9 is fixedly welded to the bridge side plate 4, so that during the rotation of the swing arm 15, the newly welded cross bar will be pushed forward to achieve step-by-step movement of the cable tray.
