Description

Technical Field

[0001] This utility model relates to the field of chain link technology, and in particular to a tool for assisting in the disassembly of chain links. Background Technology

[0002] As a key component connecting and driving the conveying parts of the dry slag machine, the chain relies on connecting links for connection between its various chains. During long-term continuous operation, the chains and transmission components of the dry slag machine will inevitably wear down, requiring replacement. After long-term operation, the connecting links used for chain connection affected by wear or corrosion are extremely difficult to disassemble. This is because the connecting link consists of three parts: two half-rings and a locking pin. Installing a new connecting link is relatively simple; just splice the two half-rings into place and press the locking pin to the middle position to complete the installation. However, when disassembling the connecting link, external tools must be used to knock out the locking pin.

[0003] Under current technological conditions, the tools required to disassemble the chain links include a hammer, a shovel, and a box for collecting locking pins. However, in actual work scenarios, the dispersed nature of these tools can easily cause many problems. For example, in complex construction site environments with limited space and frequent personnel movement, small tools such as hammers and shovels are easily lost in the chaotic environment. When workers need to disassemble the chain links urgently, they find that the tools are missing and have to search for or repurchase them temporarily. This not only greatly delays the work progress but also increases additional costs. Utility Model Content

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0031] Reference Figures 1-6 A tool for disassembling a connecting link is provided. The tool includes a main structure 100 and a disassembly and assembly component 200. The main structure 100 integrates the gun 105 and the collection box 104 into one unit, improving the integration of the tool. The disassembly and assembly component 200 makes it easy to disassemble and replace the collection box 104 for maintenance.

[0032] The main structure 100 includes a first clamping arm 101, a second clamping arm 102 hinged to one side of the first clamping arm 101 via a pin, and clamping handles 103 fixedly connected to one side of both the first and second clamping arms 101 and 102. A collection box 104 is provided on the other side of the first clamping arm 101, and a punch 105 is fixedly connected to the bottom of the other side of the second clamping arm 102. In the main structure 100, the first clamping arm 101 and the second clamping arm 102 are hinged via a pin, and the clamping handles 103 facilitate the operator's application of force. The collection box 104 is used to collect the disassembled locking pins, and the punch 105 is used to knock out the locking pins.

[0033] The disassembly and assembly component 200 is disposed on one side of the collection box 104. It includes a wedge 201 fixedly connected to one side of the collection box 104. The other side of the first clamp arm 101 is open. One side of the wedge 201 passes through the open and extends into the inner cavity of the first clamp arm 101. A docking part 202 is provided on one side of the top of the wedge 201. A slot 203 is opened on the other side of the top of the wedge 201. A snap-fit ​​part 204 is provided in the inner cavity of the slot 203. The main function of the disassembly and assembly component 200 is to facilitate the disassembly, assembly and replacement of the collection box 104, so as to meet the need for flexible use of the collection box 104 in different working scenarios.

[0034] Specifically, the docking component 202 includes a docking block 202a fixedly connected to the top of the inner cavity of the first clamping arm 101, and a docking groove 202b is provided on the other side of the top of the wedge block 201. The docking block 202a and the docking groove 202b cooperate to accurately guide the wedge block 201 to accurately dock with the first clamping arm 101 when the disassembly and assembly component 200 performs the installation operation on the collection box 104, ensuring the accuracy of the installation position of the collection box 104, thereby ensuring the structural stability of the entire tool during operation and providing a reliable foundation for the subsequent disassembly of the collection box 104.

[0035] Specifically, the locking component 204 includes a swing block 204a disposed in the inner cavity of the first clamp arm 101. A locking block 204b is fixedly connected to one side of the swing block 204a. The locking block 204b cooperates with the locking groove 203. The locking block 204b of the locking component 204 cooperates with the locking groove 203. After the collection box 104 is installed, the wedge block 201 is firmly fixed in the first clamp arm 101 to prevent the collection box 104 from shifting due to shaking, collision or other factors during tool use, which would affect the disassembly of the docking chain link and the collection effect of the locking pin.

[0036] Specifically, a rivet 204c is fixedly connected to the surface of the swing block 204a. One side of the rivet 204c is rotatably connected to the inner cavity of the first clamp arm 101. The swing block 204a is rotatably connected to the inner cavity of the first clamp arm 101 through the rivet 204c. When it is necessary to disassemble or replace the collection box 104, the operator can operate the swing block 204a to make it swing the locking block 204b, thereby separating it from the locking slot 203 and making it easier to remove the collection box 104 from the first clamp arm 101, thus improving the convenience of disassembling and assembling the collection box 104.

[0037] Specifically, the snap-fit ​​component 204 also includes a linkage block 204d fixedly connected to the other side of the swing block 204a. One side of the linkage block 204d is provided with an elastic part 204e. During normal operation, the elastic part 204e applies force to keep the snap-fit ​​block 204b and the slot 203 tightly engaged, ensuring the stability of the collection box 104 during installation.

[0038] Specifically, the elastic part 204e includes a spring 204e-1 fixedly connected to one side of the inner cavity of the first clamp arm 101. A slide cylinder 204e-2 is fixedly connected to one side of the spring 204e-1. One side of the slide cylinder 204e-2 is in contact with the linkage block 204d. When the tool is working normally, the elastic force of the spring 204e-1 is transmitted to the linkage block 204d through the slide cylinder 204e-2, causing the locking block 204b to be tightly locked into the slot 203, maintaining the fixed state of the collection box 104. When it is necessary to disassemble the collection box 104, the external force applied by the operator overcomes the elastic force of the spring 204e-1, causing the slide cylinder 204e-2 to move away from the linkage block 204d, thereby unlocking the locking member 204 and creating conditions for disassembling the collection box 104.

[0039] Specifically, the elastic part 204e also includes a slide rod 204e-3 slidably connected to the other side of the slide cylinder 204e-2. One side of the slide rod 204e-3 is fixedly connected to the inner cavity of the first clamp arm 101. The slide rod 204e-3 is slidably connected to the slide cylinder 204e-2. During the operation of the elastic part 204e, the slide rod 204e-3 plays a guiding role. It ensures that the slide cylinder 204e-2 can move stably along the slide rod 204e-3 during the extension and retraction of the spring 204e-1, avoiding the slide cylinder 204e-2 from deflection or shaking. This ensures that the elastic part 204e can play a stable and reliable role, and improves the stability and reliability of the disassembly and assembly operation of the collection box 104.

[0040] Specifically, the snap-fit ​​component 204 also includes an unlocking part 204f disposed on the other side of the linkage block 204d. A through groove 204g is provided on the top of the first clamp arm 101. The through groove 204g cooperates with the unlocking part 204f. The unlocking part 204f is disposed on the other side of the linkage block 204d. Through the through groove 204g on the top of the first clamp arm 101, the operator can easily unlock the snap-fit ​​component 204 from the outside. When it is necessary to replace the collection box 104, there is no need to disassemble other parts in a complicated way. The collection box 104 can be quickly unlocked directly through the unlocking part 204f, which greatly improves the convenience of replacing the collection box 104.

[0041] Specifically, the unlocking part 204f includes a bent plate 204f-1 that contacts the other side of the linkage block 204d. The top of the bent plate 204f-1 passes through the through groove 204g and is slidably connected to the through groove 204g. As the main component of the unlocking part 204f, the bent plate 204f-1 passes through the through groove 204g and is slidably connected to the through groove 204g. By pressing the bent plate 204f-1, the operator causes the linkage block 204d to drive the swing block 204a to swing, thereby moving the locking block 204b away from the locking groove 203, thus easily unlocking the wedge block 201. The operation is simple and direct, reducing the technical threshold for replacing the collection box 104 and improving the ease of use of the tool.

[0042] Specifically, limit blocks 204f-2 are fixedly connected to both sides of the bending plate 204f-1, and limit grooves 204f-3 are opened on both sides of the inner cavity of the through groove 204g. The limit grooves 204f-3 cooperate with the limit blocks 204f-2. The limit blocks 204f-2 on both sides of the bending plate 204f-1 cooperate with the limit grooves 204f-3 on both sides of the inner cavity of the through groove 204g to prevent the bending plate 204f-1 from shifting or falling out of the through groove 204g during the sliding process. This ensures the stability and reliability of the unlocking part 204f and ensures that the unlocking operation can be carried out continuously and stably during the replacement of the collection box 104, thereby improving the overall performance of the tool.

[0043] When in use, the operator holds the pliers handle 103 and uses the lever structure formed by the hinge of the first pliers arm 101 and the second pliers arm 102 through the pin to move the tool to the connecting link, so that the gun 105 is precisely aligned with the locking pin of the connecting link. At this time, the entire tool is in a ready-to-operate state, ready for subsequent disassembly work.

[0044] The operator uses a hammer to strike the second clamp arm 102. Since the first clamp arm 101 and the second clamp arm 102 are hinged by a pin, the impact force generated by the strike will cause the second clamp arm 102 to rotate around the pin, thereby driving the gun 105 to apply an impact force to the locking pin. Under the action of the impact force, the locking pin is knocked out and disengaged from the connecting link. The knocked-out locking pin will fall directly into the collection box 104, realizing the disassembly and collection of the locking pin and avoiding the loss of the locking pin in the complex construction site.

[0045] When installing the collection box 104, one side of the wedge 201 is inserted into the opening of the first clamp arm 101. At this time, the docking block 202a and the docking groove 202b in the docking member 202 cooperate with each other to guide the wedge 201 to be accurately inserted, achieving the initial positioning of the wedge 201. As the wedge 201 is further inserted and squeezes the locking block 204b, the locking block 204b in the locking member 204, driven by the swing block 204a, overcomes the elastic part 204e (the elastic force of the spring 204e-1) and swings outward. When the groove 203 moves to the position corresponding to the locking block 204b, the locking block 204b quickly engages with the groove 203 under the elastic force of the elastic part 204e, thereby firmly fixing the wedge block 201 inside the first clamp arm 101. During this process, the slide rod 204e-3 provides guidance for the slide cylinder 204e-2, ensuring that the slide cylinder 204e-2 can move stably along the slide rod 204e-3 during the extension and retraction of the spring 204e-1, ensuring the stable operation of the elastic part 204e, and thus ensuring the stability of the wedge block 201 installation.

[0046] When the collection box 104 needs to be disassembled, the operator presses the bending plate 204f-1 in the unlocking part 204f. The bending plate 204f-1 drives the linkage block 204d, which in turn drives the swing block 204a to rotate around the rivet 204c, causing the locking block 204b to disengage from the locking groove 203. During this process, the limiting blocks 204f-2 on both sides of the bending plate 204f-1 cooperate with the limiting grooves 204f-3 on both sides of the inner cavity of the through groove 204g to prevent the bending plate 204f-1 from shifting or falling out of the through groove 204g during the sliding process, thus ensuring the stability and reliability of the unlocking operation. Subsequently, the wedge block 201 can be removed from the first clamp arm 101 to complete the disassembly operation of the collection box 104.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
