AI Technical Summary

Technical Problem

The existing clamping device is fixed in place, making it difficult to press down on the designated area. The pressure plate is prone to forming a large angle with the equipment being lifted, making it difficult to fit tightly.

Method used

The design includes a mounting base, a linkage mechanism, a transfer mechanism, and a pressure block mechanism that are hinged in sequence. The linkage mechanism is driven to swing through the telescopic mechanism, which in turn drives the pressure block mechanism to move and lift. Combined with the slot mechanism, the relative position of the clamping device and the hoisted equipment is adjusted to ensure that the pressure block mechanism is in close contact with the equipment.

Benefits of technology

The pressing mechanism remains horizontal during movement and lifting, allowing it to better fit the suspended equipment. The mounting base moves and adjusts its position through the slot mechanism, adapting the pressing device to the shape and structure of the equipment, thus improving the pressing effect and efficiency.

Abstract

This invention relates to the field of equipment hoisting and relocation construction technology, and particularly to a clamping device and a lifting tool. The clamping device includes a mounting base, a linkage mechanism, a transition mechanism, and a pressure block mechanism that are hinged sequentially. The linkage mechanism is hinged to a telescopic mechanism. The mounting base can be adapted to connect to a slot mechanism, which includes a slot for holding the mounting base, and the mounting base can slide along the slot. During the movement and lifting process, the pressure block mechanism can maintain its structural stability through gravity, keeping its bottom plane relatively horizontal and avoiding a large angle between it and the hoisted equipment. This allows for better contact with the hoisted equipment. Simultaneously, the mounting base can move through the slot mechanism, changing the relative position of the clamping device and the hoisted equipment, enabling the pressure block mechanism to press onto a designated area. This adapts the clamping device to the shape and structure of the hoisted equipment, and the position adjustment is convenient, improving the clamping effect and efficiency.
