Description

Technical Field

[0001] This utility model relates to the technical field of positioning and locking devices, specifically to a positioning lock device. Background Technology

[0002] When lifting workpieces, the two ends of the part to be lifted are usually pre-fixed to the crane to ensure that the part is lifted more stably during the subsequent lifting process.

[0003] The common locking method is to use pre-drilled holes and bolts for locking and fixing. Therefore, workers need to rely on tools such as wrenches for assistance. Although this can improve the stability of the workpiece, it is time-consuming, laborious and inconvenient to operate during subsequent disassembly. Utility Model Content

[0004] Based on the above description, this utility model provides a positioning lock device to solve the problem that existing cranes often use bolt structures for auxiliary fixing when fixing the hoisted parts, which leads to very cumbersome subsequent disassembly.

[0005] This utility model is achieved through the following technical solution:

[0006] A positioning lock device includes a lock body with a flange on its outer side wall. Multiple through holes are formed on the surface of the flange, and the flange is bolted to an external device. An installation groove is provided inside the lock body, into which a lock cylinder is slidably inserted. Both ends of the lock cylinder extend outwards and are close to the end faces of both ends of the lock body. An adjustment assembly is also provided on the lock body, fixedly connected to one end of the lock cylinder. An elastic telescopic member is provided at the other end of the lock cylinder, located inside the lock body and fixedly connected to the lock cylinder. A lubrication assembly is also provided inside the lock cylinder and arranged near the handle.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the lock cylinder includes a fixed end and an adjusting end, wherein the diameter of the fixed end is larger than the diameter of the adjusting end, and the fixed end is slidably assembled onto the adjusting end via a threaded structure.

[0009] Furthermore, the adjustment component includes an adjustment groove disposed on the surface of the lock body. The adjustment groove extends inward and communicates with the mounting groove. A handle is disposed in the adjustment groove. The bottom end of the handle extends downward through the adjustment groove into the mounting groove and is fixedly connected to the side wall of the adjustment end. Protrusions are also provided on both sides of the handle. A sliding groove is provided on the side wall of the adjustment groove and is slidably assembled with the protrusions.

[0010] Furthermore, a limiting groove is provided on the inner wall of the mounting groove. The limiting groove is located at the connection between the fixed end and the adjusting end. An elastic telescopic member is provided in the limiting groove. One end of the elastic telescopic member is fixedly connected to the end face of the fixed end, and the other end of the elastic telescopic member is fixedly connected to the inner wall of the limiting groove.

[0011] Furthermore, the lubrication assembly includes an oil supply hole disposed inside the adjusting end and a positioning groove disposed on the side wall of the adjusting end, wherein one end of the oil supply hole extends outward to the end face of the adjusting end and forms an interface, and the other end of the oil supply hole extends inward and communicates with the positioning groove; multiple positioning grooves are provided and arranged in a circumferential array, and the multiple positioning grooves are interconnected and filled with an oil reservoir inside.

[0012] Furthermore, the oil storage component is a sponge pad, and the outward-facing side of the oil storage component is arc-shaped and flush with the surface of the lock cylinder.

[0013] Furthermore, the lock cylinder and lock body are provided with pin holes of the same size and arranged in alignment, and the pin holes on the lock cylinder are provided with threads and are locked by inserting an external screw.

[0014] Furthermore, the adjusting end extends to the outside of the lock body on the side away from the fixed end and has an annular groove on the side wall surface, and a retaining spring is provided inside the annular groove.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0016] This application improves upon the existing crane's fixing structure by replacing the traditional bolt fixing structure with a flexible telescopic positioning lock. This not only allows for locking and fixing to the pre-drilled holes through a plug-in method, but also makes telescopic adjustment more convenient. Especially when disassembling the hoisted components, no auxiliary tools are needed; the entire process can be completed by hand, greatly reducing the workload of the workers and saving time and effort.

[0023] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0025] Combination Figure 1-5 As shown, a positioning lock device includes:

[0026] Lock body 1 is the basic component of the entire positioning lock, and is fixedly connected to the crane through the flanges on both sides of lock body 1, in order to cooperate with the through holes reserved by the crane to assist in fixing the lifting equipment;

[0027] Lock cylinder 2 is located inside lock body 1 and can extend and retract inside lock body 1, thereby quickly fixing the hoisted equipment by means of plugging in, or quickly retracting it so that workers can disassemble it.

[0028] Adjustment component 3 is located at one end of lock body 1 and is used to control the extension and retraction adjustment of lock cylinder 2;

[0029] Lubrication component 4 is used to lubricate and adjust the connection between lock cylinder 2 and lock body 1.

[0030] Specifically, in this embodiment, the lock body 1 has a cylindrical structure with a cylindrical mounting groove 11 pre-reserved on its end face. This mounting groove 11 passes through the entire lock body 1. The lock body 1 is vertically positioned with a flange at its bottom, flush with the bottom surface of the flange. A through hole is pre-reserved on the flange to allow bolts to be used to fix the entire lock body 1 to the crane, facilitating the insertion and fixing of lifting components. Figure 2 As shown.

[0031] The lock cylinder 2 is divided into a fixed end 21 and an adjusting end 22. The fixed end 21 is the lower half and the adjusting end 22 is the upper half. The fixed end 21 and the adjusting end 22 can be slidably adjusted and limited by a spline structure. The entire lock cylinder 2 is vertically inserted into the lock body 1, so that both ends can extend to the outside of the lock body 1.

[0032] To prevent the lock cylinder 2 from slipping out of the lock body 1, an annular groove should be provided on the side wall of the adjusting end 22, and a retaining spring 6 should be provided inside. Therefore, when the retaining spring 6 is engaged inside the annular groove, the diameter of that part can be increased, thus using the retaining spring 6 to block the entire lock cylinder 2 and prevent it from continuing to slide downwards and disengaging from the lock body 1. In this structure, other structures, such as metal rings, can also be used instead of the retaining spring 6 for limiting the movement. The purpose of this structure is to facilitate easier disassembly and reassembly of the lock cylinder 2 and the lock body 1.

[0033] The adjustment assembly 3 includes an adjustment groove 31, a handle 32, and an elastic telescopic member 33. The adjustment groove 31 is provided on the surface of the lock body 1 and is arranged in a rectangular opening. Its length is half of the circumference of the surface of the lock body 1, so that the adjustment groove 31 is connected to the mounting groove 11 inside the lock body 1. The adjustment groove 31 is also provided with a handle 32. One end of the handle 32 passes through the adjustment groove 31 and extends into the mounting groove 11, so that it is fixedly connected to the side wall of the adjustment end 22. The other end of the handle 32 extends directly to the outside of the lock body 1 for the operator to hold. The side wall of the handle 32 should also be covered with a rubber pad to improve the comfort of holding.

[0034] The elastic telescopic member 33 is configured as a spring and is arranged at the connection between the adjusting end 22 and the fixed end 21. Here, the interior of the lock body 1, i.e., the side wall of the mounting groove 11, extends outward to form a limiting groove 12. The elastic telescopic member 33 is fitted around the adjusting end 22, with one end fixedly connected to the end face of the fixed end 21 and the other end fixedly connected to the inner side wall of the limiting groove 12.

[0035] Based on the above structure, in order to further improve the convenience of the entire positioning lock assembly structure, spring discs or other circular auxiliary connecting parts should be set at both ends of the elastic telescopic part 33. One of them should be attached to the end face of the fixed end 21, and the other end should be fixed by opening through holes in the side wall of the lock body 1 and the end face of the other spring disc, thereby using external bolts to lock it.

[0036] Therefore, in the above structure, when the operator twists the handle 32, the lock cylinder 2 will retract. That is, the fixed end 21 and the adjusting end 22 are limited by the threaded limit structure, so that the fixed end compresses the spring inward. When the spring is subjected to this, the pitch will decrease, so that the entire spring retracts inward until the fixed end is retracted into the lock body 1. At this time, the plug-in fixing structure between the fixed end and the lifted part can be disconnected.

[0037] In the above structure, the handle 32 can also be directly mounted on the end face of the adjustment end 22 located outside the lock body 1, so as to facilitate continuous rotation of the handle.

[0038] During the dismantling process, the spring is needed to maintain the above state so that the staff can remove multiple positioning locks. Therefore, a matching pin hole 5 should be provided on the top of the lock body 1 and the adjusting end 22. The positioning pin can be set inside the adjusting end 22, that is, by using the combination of the return spring and the positioning pin, it can be pre-installed inside the adjusting end 22. When the adjusting end 22 is rotated so that the two pin holes 5 are aligned, the locking is completed. Alternatively, it can be locked by external plugging.

[0039] Since the adjustment end 22 will be in direct contact with the inner wall of the mounting groove 11 of the lock body 1, in order to avoid the resistance between the two affecting the normal adjustment and use of the handle 32, it should also be lubricated with lubricating oil.

[0040] The lubrication assembly 4 includes an oil inlet 41 disposed inside the adjusting end 22. The oil inlet 41 extends outward to the end face of the adjusting end 22, forming an interface. A rubber plug or other sealing component is provided on the interface. A rectangular positioning groove 42 is formed on the side wall of the adjusting end 22. Multiple positioning grooves 42 are provided and interconnected, forming an annular structure. The other end of the oil inlet 41 communicates with this annular structure. For example… Figure 4 As shown, an oil reservoir 43 is filled inside it. The oil reservoir 43 is made of a wear-resistant sponge such as polyester sponge or melamine foam, so that the side wall of the sponge is flush with the surface of the adjustment end 22.

[0041] Therefore, when the handle 32 is rotated, the sponge that has absorbed the lubricant can take turns contacting the inner wall of the mounting groove 11 and apply oil to the side wall, reducing the friction between the adjusting end 22 and the inner wall of the mounting groove 11, making its extension and retraction adjustment smoother.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the technical solutions of the embodiments of this utility model.
