Description

Technical Field

[0001] This utility model belongs to the technical field of lifting equipment and relates to a rope-blocking device for a pulley block of a lifting equipment. Background Technology

[0002] In existing industrial smelting production processes, cranes and other lifting equipment are usually required to lift and transport goods. However, due to problems such as large swing amplitude of the hook, unreasonable lifting angle, or excessive descent of the hook, the wire rope is prone to being unloaded, and the wire rope of the hook pulley block may derail. If the wire rope of the lifting equipment is damaged, it will not only cause the lifting operation to be interrupted or fail, but also affect the continuity of production operations and increase the cost of equipment maintenance. Utility Model Content

[0003] The purpose of this utility model is to address the problems existing in the prior art by providing a rope-blocking device for a lifting equipment pulley block. This device solves the problem that the wire rope in the lifting equipment hook pulley block is prone to derailment due to excessive swing amplitude of the hook, unreasonable lifting angle, or excessive descent amplitude of the hook.

[0004] Therefore, the present invention adopts the following technical solution:

[0005] A rope-blocking device for a lifting equipment pulley block includes two rope-blocking rollers arranged symmetrically, two fixed connecting rods between adjacent rope-blocking rollers, and adjacent fixed connecting rods connected by a fixed shaft. The fixed shaft and the rope-blocking rollers are connected by a rope-blocking spring, and a fixing nut is provided at both ends of the rope-blocking rollers.

[0006] Furthermore, the fixed connecting rod is provided with limiting grooves near both ends for passing through the fixed shaft and the rope-blocking roller.

[0007] Furthermore, the rope-blocking roller is arranged parallel to the fixed shaft and perpendicular to the fixed connecting rod.

[0008] The beneficial effects of this utility model are as follows:

[0009] During use, the rope-blocking roller can rotate after contacting the wire rope, preventing wear on the wire rope. The length can be adjusted according to the diameter of the hook pulley block, and the blocking distance can be adjusted according to different diameter wire ropes. The component size can be adjusted according to different models of lifting equipment pulley blocks, effectively reducing the failure rate of lifting equipment and thus improving the working efficiency of lifting equipment. Attached Figure Description

[0010] Figure 1 This is a top view of the structure of this utility model;

[0011] Figure 2 This is a schematic diagram showing the connection relationship between the fixed shaft and the rope-blocking roller in this utility model.

[0012] In the diagram, 1-rope-blocking spring, 2-fixed shaft, 3-rope-blocking roller, 4-fixed nut, 5-fixed connecting rod. Detailed Implementation

[0013] The technical solution of this utility model will be described below with reference to the accompanying drawings and implementation methods.

[0014] like Figure 1 and 2 As shown, a rope-blocking device for a lifting equipment pulley block includes two rope-blocking rollers 3 arranged symmetrically, two fixed connecting rods 5 between adjacent rope-blocking rollers 3, and adjacent fixed connecting rods 5 connected by a fixed shaft 2. The rope-blocking rollers 3 are arranged parallel to the fixed shaft 2 and perpendicular to the fixed connecting rods 5.

[0015] The fixed shaft 2 and the rope-blocking roller 3 are connected by the rope-blocking spring 1, and the rope-blocking roller 3 is provided with a fixing nut 4 at both ends.

[0016] The fixed connecting rod 5 is provided with limiting grooves near both ends, which are used to pass through the fixed shaft 2 and the rope-blocking roller 3.

[0017] This utility model can adjust the length according to the diameter of the hook pulley block, and can adjust the distance between the two rope-blocking rollers 3 according to the wire rope of different diameters. It can adjust the component size according to the different models of lifting equipment pulley blocks, and is highly practical.
