Existing step chains mostly include the chain itself and a connecting rod. The connecting rod is used to connect the steps and is connected between the two step chains.

[0003] In the existing technology, the connection method between the chain and the connecting rod in the heavy escalator chain is mostly that a connecting sleeve is rotatably provided on the side wall of the chain, and the two ends of the connecting rod are respectively inserted into the connecting sleeves of the two step chains, and the connecting rod and the connecting sleeve are fixed by fixing parts. The common fixing part is a connecting rod, and the connecting sleeve can be provided with a rod slot. The connecting rod is slidably set in the rod slot.

[0032] The following is combined with Figure 1-3 This application is described in further detail.

[0033] The embodiment of the present application discloses a heavy-duty escalator chain disassembly and assembly device. Figures 1 to 3It includes a base 1 and two groups of chain seats 2. The base 1 is provided with two first movable grooves 11 along the length direction. The chain seats 2 are adapted to slide in the first movable grooves 11 along the width direction of the first movable grooves 11. The top wall of the chain seat 2 is provided with a chain groove 21 along the length direction. The side walls on the opposite sides of the two chain seats 2 are provided with a plurality of connecting grooves 22 that communicate with the chain grooves 21. The connecting grooves 22 pass through the top wall of the chain seat 2. A second movable groove 23 is provided inside the chain seat 2 along the length direction. A plurality of movable blocks 231 are adapted to slide in the second movable groove 23. The side walls of the chain seat 2 are mostly provided with connecting grooves 24 that communicate with the second movable groove 23. An L-shaped movable plate 241 connected to the movable block 231 is adapted to slide in the connecting groove 24. An abutment rod 242 is fixedly provided at one end of the movable plate 241 located outside the connecting groove 24. The base 1 is fixed with several positioning blocks 3 between the two sets of chain seats 2. These blocks are positioned between the two connecting slots 22. Positioning slots 31 are provided through the sidewalls of the positioning blocks 3 and connect to the top wall. The number of positioning blocks 3, connecting slots 22, moving blocks 231, moving plates 241, and abutment rods 242 is equal. The base 1 is equipped with a first moving assembly 4 for driving the two sets of chain seats 2 in opposite directions, and the chain seats 2 are equipped with a second moving assembly 5 for driving the moving blocks 231. Place the step chain that needs to be disassembled on the base 1, so that the chain is inserted into the chain groove 21, the connecting sleeve is inserted into the connecting groove 22, and the connecting rod is inserted into the positioning groove 31. Then, the second moving component 5 drives the moving block 231 and the abutment rod 242 to move, thereby fixing or releasing the step chain connecting rod structure. The first moving component 4 drives the chain seat 2 to move, thereby driving the chain to move and realize the disassembly of the connecting rod. By synchronously operating the fixing or releasing of multiple connecting rods and synchronously operating the disassembly of multiple connecting rods, the convenience of disassembling the step chain is improved.

[0034] In order to improve the convenience of moving the moving block 231, refer to Figure 1 and Figure 2 The second moving assembly 5 includes a second moving motor 51 and a third moving screw 52. The second moving motor 51 is fixed to the side wall of one end of the chain base 2. The third moving screw 52 is rotatably disposed in the second moving groove 23 and is coaxially fixedly connected to the rotating shaft of the second moving motor 51. The third moving screw 52 passes through the moving block 231 and is threadedly connected to the moving block 231. When it is necessary to move the moving block 231 to drive the abutment rod 242 to move, the second moving motor 51 is started to drive the third moving screw 52 to rotate, thereby driving the moving block 231 to rotate in the second moving groove 23, and then move in the connecting groove 24 through the mounting plate, thereby driving the abutment rod 242 to move. The operation is simple and convenient.

[0035] To improve the convenience of use, refer to Figure 1 and Figure 3The first moving assembly 4 includes a first moving motor 41, a plurality of first moving screw rods 42, a plurality of second moving screw rods 43 and a plurality of moving gears 44. A mounting block 121 is provided on the side wall of the base 1, and the first moving motor 41 is fixedly mounted on the side wall of the mounting block 121. A gear groove 12 is provided along the length direction of the base 1, and the gear groove 12 extends into the mounting block 121. The gear groove 12 is set between the two first moving grooves 11. The moving gears 44 are meshed with each other and are all rotatably set in the gear groove 12, wherein the moving gear 44 located in the mounting block 121 is coaxially fixedly connected to the rotating shaft of the first moving motor 41. The base 1 is provided with a plurality of rotating grooves 13 connected to the gear grooves 12, and the two ends of the rotating groove 13 are connected to the two first moving grooves 11. The first moving screw rod 42 and the second moving screw rod 43 have opposite threads and are both rotatably set in the rotating groove 13. The first moving screw rod 42 and the second moving screw rod 43 are respectively fixed coaxially on the side walls on both sides of a moving gear 44. There is an odd number of moving gears 44 between two adjacent first moving screws 42. When the chain base 2 needs to be moved, the first moving motor 41 is activated to rotate the moving gears 44, which in turn rotates the first and second moving screws 42, 43 within the rotation slot 13, thereby moving the chain base 2 in opposite directions within the first moving slot 11. This is simple and convenient to use.

[0036] The implementation principle of a heavy-duty escalator chain disassembly and assembly device according to an embodiment of the present application is as follows: when disassembling the step chain, place the step chain to be disassembled on the base 1, so that the chain is inserted into the chain groove 21, the connecting sleeve is inserted into the connecting groove 22, and the connecting rod is inserted into the positioning groove 31, and the connecting sleeve is rotated so that the abutment rod 242 is located between the sleeve connecting rod and the connecting rod. At this time, the second moving motor 51 is started to drive the third moving screw 52 to rotate, thereby driving the moving block 231 to move, and driving the abutment rod 242 to move through the moving plate 241, and the abutment rod 242 pushes the connecting rod to move and exit the connecting socket on the connecting rod, thereby releasing the connecting pipe between the connecting rod and the connecting sleeve. At this time, the first moving motor 41 is started to drive the moving gear 44 to rotate, and the two groups of chain seats 2 are driven to move back to each other through the first moving screw 42 and the second moving screw 43, thereby driving the chain away from the connecting rod, so that the connecting rod is separated from the connecting sleeve to complete the disassembly. During subsequent assembly, the chain is inserted into the chain slot 21 so that the connecting sleeve passes through the connecting slot 22, and the connecting rod is inserted into the positioning slot 31. At this time, the second moving motor 51 is started to drive the abutment rod 242 to move, pushing the connecting rod to compress the connecting spring. The first moving motor 41 is then started to drive the two sets of chain seats 2 to move relative to each other, so that the connecting rod is inserted into the connecting sleeve. At this time, the second moving motor 51 is started to drive the abutment rod 242 back to its initial position. Under the action of the connecting spring, the connecting rod is inserted into the connecting socket of the connecting rod, completing the connection and fixing, and completing the assembly. Compared with manual disassembly and assembly of the ladder chain, this device automatically completes the disassembly and assembly steps, and simultaneously operates the disassembly and assembly of multiple sets of connecting rods, improving the convenience of disassembly and assembly.
