Abstract
The invention discloses a method for replacing a hoisting rope of an excavator and relates to a hoisting mechanism of the excavator. The method comprises the following steps: (1) putting down a traction steel wire rope from a crane boom along a flywheel on two sides of a hoisting drum, wherein, one end of the traction steel wire rope is connected with the hoisting rope, and the other end thereof is fixed on the hoisting drum; (2) starting a hoisting motor, winding the traction steel wire rope on the hoisting drum, and braking the hoisting drum; (3) connecting one end of a short fixed steel wire rope and one end of a long fixed steel wire rope with a base, and fixedly combining the other end of the short fixed steel wire rope and the other end of the long fixed steel wire rope with a front fixed connecting plate and a back fixed connecting plate; (4) reversely rotating the hoisting drum, loosening the traction steel wire rope with the hoisting rope, and removing the traction steel wire rope; (5) starting the hoisting motor, rotating the hoisting drum to the fixed position of the hoisting rope and fixing the hoisting rope; (6) micro-rotating the hoisting drum, winding the hoisting rope, loosening the short fixed steel wire rope and the long fixed steel wire rope, braking the hoisting motor, and removing the front fixed connecting plate and the back fixed connecting plate; and (7) winding the hoisting rope and completing the replacement operation. The method not only has simple and convenient replacement operation, time-saving and effort-saving properties and high efficiency, but also ensures the safety during the replacement.
Description
Technical field
The present invention relates to the hoisting mechanism of mechanical type excavator, particularly a kind of method of changing the excavator boom hoist cable.
Background technology
The excavator boom hoist cable is a consumable accessory, needs often to change.The method of changing hoisting rope of excavator at present is to use traditional mechanism, with the pulley bracket on the wire rope process A shape frame of auxiliary volume poplar, pass canopy again to the preceding truckle of hoisting mechanism, direction along hoisting rope extends to top pulleys, fix hoisting rope down to ground, start auxiliary elevator then hoisting rope is pulled to hoisting drum.The method is time and effort consuming relatively, and it is loaded down with trivial details to work.Also there is the user that the big rope mouth that hoisting rope is pulled on the canopy is fixed earlier, bit by bit drops on again in the canopy, after two ropes are fixed, promote the driven by motor reel and begin to roll up big rope.This method also compares time and effort consuming, and efficient is on the low side.In addition, auxiliary elevator exposes work at the canopy top, has increased maintenance cost.
Summary of the invention
Purpose of the present invention is intended to overcome the shortcoming of prior art, and a kind of method of changing hoisting rope of excavator is provided, and this method is convenient field replacement operation not only, saves time, laborsaving efficient height, and the safety can guarantee to change the time.
The present invention is achieved through the following technical solutions:
A kind of method of changing hoisting rope of excavator is characterized in that: the step of changing hoisting rope is as follows:
1, in the both sides of hoisting drum, haulage cable is put down from boom upper edge head sheave, an end links to each other with hoisting rope, and an end is fixed on the hoisting drum;
2, slowly start the lifting motor, haulage cable is wrapped on the hoisting drum, when hoisting rope is wound into hoisting drum 0.5 to 1 circle, hoisting drum is braked;
3, will lack fixedly wire rope, a long fixedly end of wire rope is connected with firm banking, an other end is pressed 0.5 meter to 0.7 meter position, interval, front and back and preceding fixed connecting plate, afterwards fixed connecting plate is fixed;
4, the counter-rotating hoisting drum must not unclamp haulage cable and hoisting rope greater than 0.3 circle, and the hoisting drum that then slowly reverses unloads haulage cable;
5, start the lifting motor, hoisting drum is turned to the hoisting rope permanent position, hoisting rope is fixed;
6, the little commentaries on classics hoisting drum of beginning twines hoisting rope, makes short fixedly wire rope, long after fixedly wire rope no longer is in tensioned state, and braking promotes motor, at this moment with preceding fixed connecting plate, after fixed connecting plate unload;
7, begin to twine hoisting rope, finish and change operation.
The present invention has the following advantages compared with the prior art:
Make simply, reduced cost of production;
Utilize hoisting drum to substitute the winding action of former auxiliary elevator, save cost;
On-the-spot to change operation not only simple and convenient, saves time, laborsaving efficient height, and the safety can guarantee to change the time.
On-the-spot replacing operation does not need extra professional tool, saving fund.
Description of drawings
Fig. 1 is a kind of device schematic diagram of changing the method for hoisting rope of excavator.
The present invention is further illustrated by preferred embodiment below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 1, a kind of method of changing hoisting rope of excavator, its step of changing hoisting rope is as follows:
1, in the both sides of hoisting drum 1, haulage cable 3 is put down from boom 9 upper edge head sheaves 10, an end links to each other with hoisting rope 2, and an end is fixed on the hoisting drum 1;
2, slowly start lifting motor 8, haulage cable 3 is wrapped on the hoisting drum 1, when hoisting rope 2 is wound into hoisting drum 0.5 to 1 circle, hoisting drum 1 braking;
3, will lack fixedly wire rope 5, a long fixedly end of wire rope 6 is connected with firm banking 7, an other end is pressed 0.5 meter to 0.7 meter position, interval, front and back and preceding fixed connecting plate 4-1, afterwards fixed connecting plate 4-2 is fixed;
4, counter-rotating hoisting drum 1 must not unclamp haulage cable 3 and hoisting rope 2 greater than 0.3 circle, and the hoisting drum 1 that then slowly reverses unloads haulage cable 3;
5, start lifting motor 8, hoisting drum 1 is turned to hoisting rope 2 permanent positions, hoisting rope 2 is fixing;
6, the little commentaries on classics hoisting drum 1 of beginning twines hoisting rope 2, makes short fixedly wire rope 5, long after fixedly wire rope 6 no longer is in tensioned state, and braking promotes motor 8, at this moment with preceding fixed connecting plate 4-1, after fixed connecting plate 4-2 unload;
7, begin to twine hoisting rope 2, finish and change operation.
