Description

Technical Field

[0001] The utility model relates to the technical field of disassembly tools, and more specifically, to a conveyor chain disassembly tool. Background Art

[0002] The rain room is used for rain testing of vehicles before they leave the factory. The vehicle stops at the rain conveyor chain and passes through the rain room for rain testing. The conveyor chain runs in the harsh environment of rain for a long time, which leads to frequent maintenance and inspection of the conveyor chain. Among them, the maintenance and inspection of the conveyor chain gears are the most frequent. There is one conveyor chain gear at each end of the vehicle. When checking the gear at the vehicle end, it is necessary to turn over the conveyor chain on the gear, which requires two people to operate, which is extremely time-consuming and causes waste of manpower and time.

[0003] When checking the gears at the inlet end of the rain conveyor chain, the entire conveyor chain needs to be turned over to see the gears. The conveyor chain is about 100 meters long and the entire chain is in a taut state. The inlet end cannot be disassembled directly. Traditional disassembly requires reversing the conveyor chain from the outlet end of the conveyor chain so that the chain plate at one end of the conveyor chain is squeezed and bulges. The bulge reaches a certain height before the connecting shaft of the conveyor chain can be disassembled. However, since the conveyor chain drive motor is at the outlet end, the bulge of the conveyor chain generated by the reversal is at the outlet end. However, when the conveyor chain at the inlet end needs to be disassembled, it needs to be disassembled to the inlet end in more than a dozen groups, and two people are required to cooperate in the disassembly, resulting in waste of personnel and time. If a certain section in the middle of the conveyor chain needs to be disassembled, it is also necessary to start disassembly from the outlet end when necessary. After disassembling one group, the next group of conveyor chains can be disassembled, resulting in low work efficiency and waste of personnel.

[0004] Prior art CN213616469U discloses a conveyor chain lateral chain plate disassembly device, including a support main board, a lower pull claw is provided at the lower end of the support main board, a handle is fixed on the lower end face of the lower pull claw, a support screw is welded on the upper end of the support main board and an upper pull claw is sleeved on the support screw, a reinforcement plate is welded on the middle part of the side of the support main board, a threaded push rod is traversed in the middle of the support main board and the reinforcement plate, a flange turntable is fixed at the rear end of the threaded push rod, and a limit plate and a center push block are provided at the front end of the threaded push rod. The utility model discloses a conveyor chain lateral chain plate disassembly device, holding the handle to buckle the hook teeth of the lower pull claw on the lower end of the chain plate, then adjusting the fixing nut to lower the upper pull claw and buckle it on the upper end of the chain plate to achieve clamping, then rotating the threaded push rod through the flange turntable to hold the pin shaft, and continuing to rotate the threaded push rod to push out the pin shaft to achieve the disassembly of the conveyor chain. When the protruding position does not correspond to the position of the conveyor chain to be disassembled, the device also needs to disassemble the conveyor chain in groups, which is time-consuming and laborious. Utility Model Content

[0005] In order to solve the above problems, the utility model proposes a conveyor chain disassembly tool, which passes through the raised part of the conveyor chain through a roller, and then connects the traction component to the two ends of the raised part. The staff drags the traction component, and under the drive of the traction component, the roller moves the raised position of the conveyor chain to the position where the conveyor chain needs to be disassembled, and then the ejector pin assembly is used to eject the connecting shaft of the conveyor chain, thereby completing the disassembly of any position of the conveyor chain, and the operation is simple and convenient.

[0006] To achieve the above-mentioned purpose, the present scheme provides a conveyor chain disassembly tool, including a traction assembly, a roller and a pin assembly, wherein the roller is detachably mounted at both ends of the bottom of the traction assembly, the length of the roller is adapted to the width of the conveyor chain, and a gap is formed between the traction assembly and the roller for the conveyor chain to pass through, and the pin assembly is arranged on one side of the traction assembly and corresponds to the position of the connecting shaft of the conveyor chain, and is used to eject the connecting shaft of the conveyor chain.

[0007] In this technical solution, the staff first reverses the driving motor so that the outgoing end of the upper conveyor chain protrudes to a certain height, extends the roller under the protruding conveyor chain, and the two ends of the roller protrude a small section of the conveyor chain. The two ends of the roller are then installed at the bottom of the traction assembly, and the traction assembly is dragged to the position of the conveyor chain to be disassembled. Due to the gap formed between the traction assembly and the roller, the roller slides at the bottom of the upper conveyor chain and moves the protrusion to a specific position. During this process, the conveyor chain slides relative to the gap. During the movement, the position of the ejector assembly always corresponds to the connecting shaft of the conveyor chain. Finally, the connecting shaft is ejected by the ejector assembly to complete the disassembly of the conveyor chain at the specific position.

[0008] As a preferred solution, in order to prevent the traction assembly and the roller from interfering with the conveyor chain during movement, the traction assembly includes a connecting rod and two protruding structures. The bottom width of the connecting rod is adapted to the length of the roller. The two protruding structures are respectively arranged at the two ends of the bottom of the connecting rod. The height of the protruding structure is greater than the height of the conveyor chain. The two ends of the roller are respectively installed on the two protruding structures. A quadrilateral gap is formed between the roller and the protruding structure for the conveyor chain to pass through. The staff can drive the roller to move under the upper conveyor chain by dragging the top of the connecting rod.

[0009] As a preferred solution, in order to limit the roller, the roller includes a first shaft segment and two second shaft segments arranged at both ends of the first shaft segment, the diameter of the first shaft segment is larger than the diameter of the second shaft segment so that a step is formed at the connection between the first shaft segment and the second shaft segment, and each second shaft segment is respectively installed on each of the protruding structures. In the process of the traction assembly driving the roller to move, the protruding mechanism abuts against the step to clamp the first shaft segment between the two protruding structures to prevent the roller from detaching from the traction assembly.

[0010] As a preferred solution, in order to prevent the ejector assembly from interfering with the conveyor chain, one end of the ejector assembly is connected to one end of the connecting rod, and the other end of the ejector assembly is suspended outside the connecting rod and corresponds to the connecting shaft position of the conveyor chain.

[0011] As a preferred solution, the ejector assembly includes a mounting seat and an ejector, the mounting seat is an L-shaped structure, one end of the mounting seat is connected to one end of the connecting rod, the other end of the mounting seat is provided with a threaded hole, the ejector is parallel to the roller and is screwed on the threaded hole, one end of the ejector is provided with a screwing structure for rotation, one end of the ejector is screwed into the threaded hole, the ejector can be screwed forward by hand or with a screwdriver so that one end of the ejector contacts the connecting shaft of the conveyor chain and ejects it, and the cooperation between the threaded hole and the ejector of the ejector assembly can achieve a labor-saving effect.

[0012] As a preferred solution, hooks are respectively provided at both ends of the bottom of the connecting rod in the vertical direction, and the hooks form the protruding structure. The second shaft segments are respectively clamped on the hooks, and can be conveniently connected to the roller through the hooks. The hooks can play a one-way anti-detachment effect during the dragging process. The hook has a notch. After disassembly, the second shaft segments at both ends of the roller are removed from the openings of the hooks, so the traction assembly and the roller can be easily separated.

[0013] As a preferred solution, in order to ensure smooth movement of the roller, one end of each second shaft segment away from the first shaft segment is rotatably connected to a guide wheel, and the guide wheel can roll along the base of the conveyor chain, thereby reducing the friction between the roller and the base.

[0014] As a preferred solution, since the position between the protrusion structure and the connecting rod is subjected to greater force, in order to prevent the protrusion structure and the connecting rod from breaking due to fatigue, a reinforcing rib is provided between the connecting rod and the protrusion structure.

[0015] As a preferred solution, in order to facilitate the staff to drag with one hand, a T-shaped handle is provided on the top of the connecting rod.

[0016] As a preferred solution, in order to reduce the wear between the first shaft segment and the upper conveying chain and the base, the first shaft segment is made of metal with a smooth surface.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. The hand-pull traction assembly of the utility model drives the roller to slide at the bottom of the upper conveyor chain, so that the raised part of the conveyor chain can be moved to a specific position, and then the conveyor chain at the specific position can be disassembled through the ejector assembly, which can save the workload of disassembling the entire conveyor chain, saving time and effort.

[0019] 2. The connecting shaft of the conveyor chain can be ejected by the ejector assembly arranged on one side of the traction assembly, which can avoid the staff from using other tools for dismantling and improve the convenience of disassembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Embodiment 1:

[0029] like Figures 1 to 4The present embodiment provides a conveyor chain disassembly tool, including a traction component 1, a roller 2 and a pin assembly 3. The roller 2 is detachably mounted at both ends of the bottom of the traction component 1. The length of the roller 2 is adapted to the width of the conveyor chain 6. A gap is formed between the traction component 1 and the roller 2 for the conveyor chain 6 to pass through. The pin assembly 3 is arranged on one side of the traction component 1 and corresponds to the position of the connecting shaft 601 of the conveyor chain 6, and is used to eject the connecting shaft 601 of the conveyor chain 6.

[0030] In this embodiment, the conveyor chain 6 is composed of main components such as chain plates and a connecting shaft 601 , and the chain plates are connected by the connecting shaft 601 .

[0031] In the present embodiment, the traction assembly 1, the roller 2 and the ejector assembly 3 are all made of stainless steel. Before disassembly, the staff first reverses the drive motor. Since the drive motor is close to the outgoing end of the conveyor chain 6, the chain plate of the conveyor chain 6 close to the outgoing end is squeezed and a bulge is generated. Since the conveyor chain 6 is too heavy, the conveyor chain 6 cannot be lifted by hand to move the raised position. If it is necessary to disassemble the conveyor chain 6 close to the incoming end, it is necessary to first extend the bottom of the raised part of the roller 2, and then connect its two ends to the bottom of the traction assembly 1. The staff can drive the roller 2 to slide at the bottom of the upper conveyor chain 6 by pulling the top of the traction assembly 1 toward the incoming end, thereby moving the raised position to the incoming end. Finally, the staff can disassemble the conveyor chain 6 at the incoming end by ejecting the connecting shaft 601 between the chain plates through the ejector assembly 3.

[0032] Specifically, the traction assembly 1 includes a connecting rod 101 and two protruding structures 102. The bottom width of the connecting rod 101 is adapted to the length of the roller 2.

The height of the protruding structure 102 is greater than the height of the conveying chain 6. The two ends of the roller 2 are respectively installed on the two protruding structures 102, and the gap is formed between the roller 2 and the protruding structure 102.

[0033] In this embodiment, the connecting rod 101 is an inverted T-shaped mechanism, which consists of a horizontal rod and a vertical rod.

The diameter of the first shaft segment 201 is greater than the diameter of the second shaft segment 202 so that a step is formed at the connection between the first shaft segment 201 and the second shaft segment 202. Each second shaft segment 202 is respectively installed on each of the protruding structures 102. The first shaft segment 201 is made of metal with a smooth surface.

[0035] In this embodiment, the first shaft segment 201 and the second shaft segment 202 are formed by turning and then polished.

[0036] Specifically, two ends of the bottom of the connecting rod 101 are respectively provided with hooks along the vertical direction, the hooks form the protruding structure 102, and each of the second shaft segments 202 is respectively clamped on each of the hooks.

[0037] In this embodiment, an opening is formed at one end of the hook, and the second shaft segment 202 is engaged with the hook through the opening. The hook design can facilitate the installation and removal of the roller 2.

[0038] Specifically, one end of the ejector assembly 3 is connected to one end of the connecting rod 101, and the other end of the ejector assembly 3 is suspended on the outside of the connecting rod 101 and corresponds to the position of the connecting shaft 601 of the conveying chain 6. The ejector assembly 3 includes a mounting seat 301 and an ejector 302. The mounting seat 301 is an L-shaped structure. One end of the mounting seat 301 is connected to one end of the connecting rod 101, and the other end of the mounting seat 301 is provided with a threaded hole. The ejector 302 is parallel to the roller 2 and is screwed on the threaded hole. One end of the ejector 302 is provided with a screwing structure for rotation.

[0039] In this embodiment, one end of the mounting seat 301 is welded to one end of the cross bar, and the ejector pin 302 may be a threaded pin, the diameter of which is less than or equal to the diameter of the connecting shaft 601 .

[0042] In this embodiment, the guide wheel 4 is made of nylon material, and the guide wheel 4 rolls on the base of the conveyor chain 6 to further lift the conveyor chain 6, thereby reducing the friction between the roller 2 and the base of the conveyor chain 6, so that the roller 2 moves more smoothly.
