Description

Technical Field

[0001] The utility model relates to the technical field of battery production equipment maintenance, in particular to a maintenance tool for a drive chain of a plate chain production line. Background Art

[0002] During lead-acid battery production, plate chains are a crucial conveyor. Large-scale and long production lines often pose significant challenges for repair and maintenance, particularly the drive chain. The drive chain is the primary driving link that transfers power from the drive motor to the floor chain. It is an endless chain installed beneath the floor chain. Circular toothed wheels are located at each end of the endless chain. One end is connected to the drive motor, while the other end is connected to the chain tensioner. To ensure smooth operation of the floor chain, the tensioner applies tension to the entire chain, keeping it taut.

[0003] Currently, every time a plate chain production line's drive chain is repaired, the tensioner must be loosened before any repair or maintenance can be performed. Due to the drive chain's large size and length, even with the tensioner loosened, it's difficult to maintain a relaxed chain. Connecting the last two links is particularly challenging when replacing chain links. Manual hoists or other tools are required to retract the disconnected section of the chain until it can be reconnected. This is not only cumbersome and labor-intensive, but also time-consuming, hindering rapid repairs and impacting the efficiency of lead-acid battery production.

[0004] Patent document CN202241149U discloses a plate chain production line drive chain maintenance tool. When the drive chain of the plate chain production line needs to be connected, the utility model is first placed between the upper chain and the lower chain of the drive chain. Then, the hooks at the bottom of the first and second positioning seats are inserted into the two ends of the chain disconnection, leaving the connection position of the chain. Then, the tensioning screw and the supporting screw are rotated simultaneously by hand or with a pneumatic wrench. As the tensioning screw rotates in place relative to the first bracket, the supporting screw rotates in place relative to the second bracket, and the first nut sleeve moves axially on the tensioning screw, and the second nut sleeve moves axially on the supporting screw, thus shrinking the distance between the two hooks. The hook tightens the chain, shrinking the chain disconnection to a connectable state. At this time, components such as pins, washers and retaining springs are installed to connect the two ends of the chain disconnection. After the connection is completed, the tensioning screw and the supporting screw are rotated in the opposite direction to open the two hooks, and the utility model can be removed from the chain. However, the chain portion on the upper side of some plate chains is located above the frame. After the connecting ends of the chains are pulled closer using the maintenance tool, during the process of connecting the chains, the lower end of the chain is blocked by the frame, and the upper end of the chain is close to the maintenance tool. The operable space between the maintenance tool and the upper end of the chain is small, making it inconvenient to install the chain rollers into the chain.

[0005] Patent document CN202192599U discloses a hook-type chain repairer. When the drive chain of a plate chain production line needs to be connected, the utility model is first placed between the upper and lower chains of the drive chain. Then, the hook heads at the bottom of the first and second hooks are inserted into the two ends of the chain break, leaving a connection position for the chain. The tensioning screw is then rotated by hand or with a pneumatic wrench. The tensioning screw rotates in place relative to the bracket. The two balance arms serve as support, and the nut is sleeved on the tensioning screw for axial movement. This shrinks the distance between the hook heads at the bottom of the two hooks. The hooks tighten the chain, causing the chain break to shrink to a connectable state. At this time, pins, washers, and retaining springs are installed to connect the two ends of the chain break. After the connection is completed, the tensioning screw is rotated in the opposite direction to open the hook heads at the bottom of the two hooks, and the utility model can be removed from the chain. During the chain connection process, the lower end of the chain is blocked by the frame, while the upper end of the chain is close to the maintenance tool. The available space between the maintenance tool and the upper end of the chain is small, making it difficult to install the chain rollers into the chain. When the maintenance tool is pulled closer to the chain, sufficient space is required above the chain for the first and second grab hooks to move, making it unsuitable for connecting chains in a small space. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a tool for driving a chain maintenance device for a plate chain production line which is convenient for pulling the two connecting ends of the chain closer together, staggering the space above the chain, and facilitating connection of the two connecting ends of the chain.

[0007] In order to achieve the above purpose, the technical solution provided by the utility model is:

[0008] The plate chain production line drive chain maintenance tooling includes two clamping parts, which are slidably connected to the sliding rod, and the two clamping parts are respectively threadedly connected to the threaded sections on both sides of the bidirectional screw. The clamping part includes a hook plate, and the hook plate includes a vertical part on the lower side and a straight part on the upper side. A clamping groove is provided at the lower end of the vertical part of the hook plate, and a connecting block is fixed at one end of the straight part of the hook plate away from the vertical part of the hook plate. The sliding rod passes through the connecting block, and the bidirectional screw is threadedly connected to the connecting block.

[0009] Specifically, a fixing block is concentrically fixed in the middle of the bidirectional screw.

[0010] Specifically, the vertical portion on the lower side and the flat portion on the upper side of the hook plate are integrally formed.

[0011] Specifically, the sliding rod is parallel to the bidirectional screw.

[0012] Specifically, the sliding rod is a square rod.

[0013] Specifically, the connection blocks are all threadedly connected with adjusting bolts, and the adjusting bolts are vertically arranged.

[0014] Specifically, a universal ball is installed at the lower end of the adjusting bolt.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. Since the hook plate includes a vertical portion on the lower side and a straight portion on the upper side, the bidirectional screw and the slide rod are both connected to the connecting block fixed on the straight portion of the hook plate. Therefore, when the two connecting ends of the chain are pulled closer by using the two clamping pieces, the operating space above the two connecting ends of the chain can be cleared. When the two connecting ends of the chain are connected, it is convenient to install the rollers of the chain and to thicken the two ends of the pin shaft of the chain.

[0017] 2. By setting the adjusting bolts, after the roller of the chain is stuck in the slot, the two adjusting bolts are rotated so that the universal ball at the lower end of the adjusting bolt contacts the plate chain or the frame, thereby preventing the maintenance tool from tilting and preventing the roller of the chain from falling out of the slot, providing a fulcrum for the maintenance tool and improving the stability of the maintenance tool.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Example 1: Reference Figure 1-Figure 3 As shown, the plate chain production line drive chain maintenance tool includes two clamping parts, and the two clamping parts are slidably connected to the slide bar 6.

[0024] The two clamping pieces are respectively threadedly connected to the thread segments on both sides of the bidirectional screw 7, and a fixing block 8 is concentrically fixed to the middle of the bidirectional screw 7. The sliding rod 6 is parallel to the bidirectional screw 7.

[0025] The clamping member includes a hook plate 1, which comprises a vertical portion at the bottom and a flat portion at the top. These portions are integrally formed. A slot 2 is defined at the bottom end of the vertical portion of the hook plate 1. A connecting block 3 is secured to the end of the flat portion of the hook plate 1, distal from the vertical portion. A sliding rod 6 extends through the connecting block 3, and a bidirectional screw 7 is threadedly connected to the connecting block 3.

[0026] When the two connecting ends of the chain need to be connected, the roller of the chain is clamped in the clamping groove 2 of the hook plate 1, and the broken end of the chain is located between the two hook plates 1. Then, the two-way screw rod 7 is rotated by cooperating with the wrench and the fixing block 8, so that the two clamping parts are close to each other. When the two clamping parts are close to each other, the two connecting ends of the chain are close to each other. When the two connecting ends of the chain reach the connection position, the two connecting ends of the chain are connected. During the connection process of the two connecting ends of the chain, since the two-way screw rod 7 and the sliding rod 6 are both connected to the connecting block 3 fixed on the straight part of the hook plate 1, when the two clamping parts pull the two connecting ends of the chain together, the operating space above the two connecting ends of the chain can be cleared, making it convenient to install the roller of the chain and to perform roughening on the two ends of the pin shaft of the chain.

[0027] The connecting blocks 3 are all threadedly connected with adjusting bolts 4, which are vertically arranged. A universal ball 5 is installed at the lower end of the adjusting bolts 4.

[0028] By setting the adjusting bolt 4, after the roller of the chain is stuck in the slot 2, the two adjusting bolts 4 are rotated so that the universal ball 5 at the lower end of the adjusting bolt 4 contacts the plate chain or the frame 9, thereby preventing the maintenance tool from tilting, preventing the roller of the chain from falling out of the slot 2, providing a fulcrum for the maintenance tool, and improving the stability of the maintenance tool.

[0029] Example 2: Based on Example 1, the slide bar 6 is a square bar. When the slide bar 6 is a square bar, the two clamping members cannot rotate about the axis of the slide bar 6. Therefore, the vertical portions of the hook plates 1 of the two clamping members are always located on the same side. When installing this repair tool, the rollers on both sides of the chain break are conveniently clamped in the clamping grooves 2 of the hook plates 1 of the two clamping members.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
