Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing, specifically to a lifting roller hoisting and fixing mechanism. Background Technology

[0002] In the field of lifting and hoisting equipment in mechanical manufacturing, the hoisting of rollers in three-dimensional lifting platforms is a crucial operation. Currently, the common practice in this field is to manually hoist rollers using slings and chain hoists. This traditional method lacks specialized hoisting tools, leading to numerous problems in actual operation, such as the aforementioned uneven force distribution, swaying, and safety hazards, seriously affecting production safety and efficiency. Existing similar technical solutions mainly utilize a simple combination of slings and chain hoists for roller hoisting. Its structure primarily consists of slings and chain hoists; the slings are manually wrapped around the roller, and then the chain hoist is used for the hoisting operation. This solution has a simple structure, with components mainly connected by manual binding, lacking specialized fixing and positioning structures, making it difficult to guarantee the stability of the roller during hoisting. There are also difficulties in secondary handling after hoisting, posing significant safety hazards and easily causing injury to operators; the operating space is limited, and the rollers often interfere with the guardrails when hoisting, resulting in secondary damage to the rollers. Damaged rollers and drive belts wear out faster, posing a risk of belt breakage, which not only affects production output but also threatens the lives of on-site operators. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a lifting and fixing mechanism for rollers that is widely applicable, simple in structure, low in manufacturing cost, easy to use, prevents roller swaying, facilitates hoisting, and is safe and reliable. This solves the problems of uneven force distribution and lateral swaying during roller hoisting in existing technologies, thereby improving the safety and efficiency of hoisting. The specific technical solution is as follows: A lifting roller hoisting and fixing mechanism includes a locking block, fixing bolt holes, reinforcing ribs, a semi-circular clamping plate, a side positioning clamping pin, and a lifting hole. The locking blocks are provided in two pairs and are symmetrically positioned vertically, one pair of upper locking blocks and one pair of lower locking blocks, with a pair of fixing bolt holes corresponding to each locking block; the curved surface of the semi-circular clamping plate is consistent with that of the roller, and a pair of semi-circular clamping plates are symmetrically arranged; a reinforcing rib is provided at the contact position between the locking block and the semi-circular clamping plate; a side positioning locking pin is provided at the center position of the outer side of the semi-circular clamping plate 4; and a lifting hole is provided at the upper part of the pair of upper locking blocks.

[0004] Furthermore, four pairs of reinforcing ribs are provided, which are welded to the locking block and the semi-circular retaining plate respectively.

[0005] Furthermore, mounting bolts are provided to match the fixing bolt holes, thereby fixing the locking block to other components and ensuring the stability of the overall structure.

[0006] Furthermore, the semi-circular card plate 4 is made of thick metal with a thickness of 5-10mm.

[0007] When using the hoisting tool, lock the roller to the side of the semi-circular clamping plate, then tighten the locking block, fix it with bolts through the fixing bolt holes, and then fix the center position of the side with the side positioning clamping pin. After the two bolts of the fixing clamping plate are locked and fixed, use the safety bolt at the lifting hole position to lift it. This will ensure the reliability and stability of the roller during the lifting process.

[0008] This utility model has the following advantages: Wide applicability: The structural design of this device can adapt to different specifications of three-dimensional lifting rollers, meeting various hoisting needs. Simple structure: The overall structure is clearly defined, and the functions of each component are clearly defined, facilitating manufacturing and maintenance. Low manufacturing cost: The materials and components used are relatively common, and the processing technology is relatively simple, reducing manufacturing costs. Easy to use: The operation process is clear; the roller hoisting can be completed through simple locking and fixing operations, reducing the labor intensity of operators. Safe and reliable: Through the cooperation of components such as the semi-circular clamping plate, locking block, and positioning locking pin, the roller can be stably fixed, effectively preventing uneven force distribution and swaying during hoisting, eliminating safety hazards such as falling, and avoiding damage caused by interference between the roller and the guardrail, thus improving production safety and reliability.
