Embodiment 1

[0110] In order to form an assembly with the steel wire rope assembly seat 6, it not only ensures the structural stability after assembly, but also ensures the formation of a rotational connection with the steel wire rope assembly seat 6 after installation, which is convenient for the adjustment of the corresponding steel wire rope. There are certain structural requirements, as described below;

[0111] The upper steel wire rope assembly 2 includes four upper steel wire ropes 201, the upper ends of the upper steel wire ropes 201 are bound and fixed with a first ring sleeve 202 through an aluminum alloy pressure sleeve 7, and the lower ends of the upper steel wire ropes 201 are bound with a second ring sleeve 203 through an aluminum alloy pressure sleeve 7;

[0112] The upper wire rope 201 is connected to the hook of the lifting device through the first ring sleeve 202;

[0113] The second ring sleeve 203 of the upper wire rope 201 is sheathed in the U-shaped groove 10 of the f...

Embodiment 2

[0118] In order to form a connection with the extension arm assembly 4 added in this embodiment, the lower wire rope 301 and the extension arm assembly 4 have certain structural requirements, specifically as follows:

[0119] The lower steel wire rope assembly 3 includes four lower steel wire ropes 301, and the lower end of the lower steel wire ropes 301 is bound and fixed with a fourth ring sleeve 303 through the aluminum alloy compression sleeve 7;

[0120] The fourth ring sleeve 303 of the lower wire rope 301 is sheathed in the U-shaped groove 10 of the third sleeve 406 and forms a rotational connection with the third sleeve 406 .

[0121] Similar to the structural principle in Embodiment 1, a third shaft 405 and a third bushing 406 are installed on the upper part of the extension arm assembly 4, wherein the middle part of the third bushing 406 is formed with U-shaped grooves 10 distributed along its radial direction. The third shaft sleeve 406 cooperates, and the lower end...

Abstract

The invention discloses an improved frame-type lifting device, which comprises a frame assembly and a wire rope mechanism, the wire rope mechanism includes an upper wire rope assembly and a lower wire rope assembly; wire rope assembly seats distributed along the circumference of the frame assembly; assembled on The extension arm assembly at the end of the lower wire rope assembly away from the support frame assembly; the extension arm assembly is equipped with an extension seat assembly at the end of the extension arm assembly away from the lower wire rope assembly, and the extension seat assembly is fixedly connected with the suspended equipment so as to be suspended The equipment is fixed in the lifting space; the upper end of the extension arm assembly is higher than the centroid height of the equipment being hoisted. The hoisting device of the present invention is designed with a steel wire rope assembly seat as a force-bearing structure, and the steel wire rope is divided into eight groups of upper and lower groups and connected to the corresponding bushings respectively, avoiding the cumbersome and complicated adjustment process of repeating multiple times, and the pressure plate in the prior art For the problem that it is difficult to control the pressing force of the steel wire rope and damage the steel wire rope.

Description

technical field [0001] The invention relates to the technical field of optomechanical-electrical integration equipment carrying, in particular to an improved frame-type lifting device suitable for carrying medium and large equipment with irregular shapes. Background technique [0002] Due to the special structure, large volume and irregular shape of medium and large optical telescopes, radio telescopes, machine tool turntables and other opto-mechanical integration equipment, the usual lifting frame structure often cannot meet the requirements. A frame-type lifting device that can meet lifting and carrying requirements. [0003] Frame-type hoisting device in the prior art, participate in Figure 1 to Figure 5 As shown, among them, figure 1 It shows a schematic diagram of the working state of a frame-type lifting device in the prior art; the frame-type lifting device mainly includes a frame assembly 1, a steel wire rope 2, a suspended equipment 3, an extension seat assembly ...
