Abstract

This invention discloses a method for replacing wire ropes in lifting equipment. Before replacing the worn-out wire rope, the hoisting mechanism drum is rotated and lowered to its lowest position. The old wire rope on the drum is lowered to its lowest position. The pressure plate at point A1 on one side of the wire rope on the hoisting mechanism drum is loosened, and the old wire rope at point A1 is lowered and connected to the new wire rope at point A to be replaced. After the connection is secure, the hoisting mechanism is started, and the new wire rope is threaded through the ground pulley and the top pulley step by step using the hoisting mechanism. When end A is raised to the position of the lifting mechanism drum, disconnect the connection between the old and new wire ropes A1 and end A, and temporarily fix end A of the new wire rope; lower one end A1 of the old wire rope, connect end A1 of the old wire rope to end B of the new wire rope, raise end B of the new wire rope to the drum height, disconnect the connection between end A1 and end B, temporarily fix end B, loosen the old wire rope completely, and adjust the position of the drum wire rope pressure plate; install ends A and B of the new wire rope respectively, and the new wire rope can be put into use.

Description

An operation method for replacing steel wire ropes of hoisting equipment

technical field

The invention relates to an operation method for replacing steel wire ropes of lifting equipment.

Background technique

Domestic hoisting equipment (door crane/travel) lifting mechanism steel wire rope replacement is one of the daily tasks of equipment maintenance units. Due to the high utilization rate of equipment, the wire rope of the lifting mechanism is worn and other reasons lead to the replacement operation. The traditional replacement method is manual dismantling in the whole process. Picking and installation, in order to disassemble and install the steel wire rope between the ground wheel set and the sky pulley, 4 workers are required to manually pass through the pulleys of each level one by one, and use the hemp rope to lift up and down in place. The labor efficiency is low and the time is long. .

Contents of the invention

The object of the present invention is to provide an operation method for replacing the steel wire rope of the lifting equipment. The original equipment hoisting mechanism is used to rotate, the old steel wire rope is connected to the new steel wire rope, and the new steel wire rope is pulled and worn between the pulley blocks by the equipment hoisting mechanism. Realize semi-automatic installation of wire rope.

The purpose of the present invention is achieved in this way, an operation method for replacing the steel wire rope of the lifting equipment, before replacing the scrapped steel wire rope, the lifting mechanism reel is rotated and lowered, the old steel wire rope on the reel is put down to the lowest position, and the lifting mechanism reel Loosen the pressure plate at one end A1 of the steel wire rope on one side, put down the A1 end of the old steel wire rope and connect the A1 end of the new steel wire rope that needs to be replaced; start the lifting mechanism after the connection is firm, and use the lifting mechanism to lift the new steel wire rope step by step from the ground pulley and sky pulley Putting on, when the end A of the new steel wire rope reaches the position of the lifting mechanism drum, remove the connecting piece between the old and new steel wire rope A1 and the A end, and temporarily fix the A end of the new steel wire rope; put down the A1 point of the old steel wire rope, and connect the A1 end of the old steel wire rope with the new steel wire rope End B, after the connection is firm, use the lifting mechanism to lift the B end of the new steel wire rope to the height of the drum, release the connecting piece between the A1 end and the B end, temporarily fix the B end, use the lifting mechanism drum to loosen all the old wire ropes, and adjust the drum wire rope Position of the pressure plate: Install the A and B ends of the new steel wire ropes respectively, and the new steel wire ropes are installed and put into use for trial run.

After the actual operation of on-site replacement of the lifting wire rope of the lifting equipment, it only takes 40 minutes to replace the wire rope of a 35-ton lifting equipment. Intensity is reduced and employee reviews are good. The working method for semi-automatically replacing the steel wire rope of the hoisting equipment is suitable for the replacement work of the lifting wire rope of the hoisting equipment, and has wide application prospects.

Description of drawings

The present invention will be described in further detail below in conjunction with the accompanying drawings.

Fig. 1 is the working state figure that the method of the present invention replaces steel wire rope.

Detailed ways

An operation method for replacing steel wire ropes of lifting equipment, as shown in Figure 1, before replacing scrapped steel wire ropes, the lifting mechanism drum 1 is rotated and lowered, the old steel wire rope on the drum 1 is lowered to the lowest position, and the lifting mechanism drum 1 Loosen the pressure plate at one end A1 of the wire rope on one side, put down the A1 end of the old wire rope and connect the A end of the new wire rope 5 that needs to be replaced; start the lifting mechanism after the connection is firm, and use the lifting mechanism to pull the new wire rope from the ground pulley 3 and sky pulley 2. Dress up step by step. When the end A of the new steel wire rope reaches the position of the drum 1 of the lifting mechanism, remove the connecting piece 4 between the old and new steel wire rope A1 and the A end, and temporarily fix the end point A of the new steel wire rope; put down the A1 point of the old steel wire rope, and connect the old one. Wire rope A1 end and new wire rope B end, after the connection is firm, use the lifting mechanism to raise the new wire rope B end to the height of drum 1, remove the connecting piece 4 between A1 end and B end, temporarily fix B end, and use the lifting mechanism drum 1 to lift All the old steel wire ropes are loosened, adjust the position of the drum steel wire rope pressure plate; install the new steel wire ropes A and B ends respectively, and the new steel rope 5 is installed and put into use for trial run.

Claims (1)
