Embodiment Construction

[0014] Such as figure 1 As shown, a fixing device for replacing the hoisting rope of an excavator includes: a hoisting drum 1 , a hoisting rope 2 , and a traction wire rope 3 connected to the hoisting drum 1 and the hoisting rope 2 . Two fixed connecting plates are installed at intervals front and rear on the lifting rope 2, the front fixed connecting plate 4-1 is connected with one end of the short fixed steel wire rope 5, the rear fixed connecting plate 4-2 is connected with one end of the long fixed steel wire rope 6, and the short fixed The other end of steel wire rope 5, long fixed wire rope 6 is fixedly connected with fixed base 7. Connect the long and short wire ropes at one end, and after tensioning, it can better ensure the locking of the hoisting rope, and the fixing is convenient and simple.

[0015] Such as image 3 , 4 As shown, the front fixed connecting plate 4-1 and the rear fixed connecting plate 4-2 have the same structure, and are connected at one end by ...

Abstract

The invention discloses a fixing device for replacing a hoisting rope of an excavator, which relates to a lifting mechanism of a mechanical excavator. The fixing device is characterized in that the hoisting rope is provided with two fixed connecting plates at intervals on the front part and the rear part, the front fixed connecting plate is connected with one end of a short fixing steel wire rope, the rear fixed connecting plate is connected with one end of a long fixing steel wire rope, and the other ends of the short fixing steel wire rope and the long fixing steel wire rope are fixedly connected with a fixed base. By adopting the fixing device, not only the field replacement is convenient to operate, is time-saving and labor-saving, and has high efficiency, but also the security can beensured during replacement. Simultaneously, the fixing device has the advantage of simple manufacture.

Description

technical field [0001] The invention relates to a lifting mechanism of a mechanical excavator, in particular to a fixing device for replacing the hoisting wire rope of the excavator. Background technique [0002] The hoisting wire rope of the excavator is a vulnerable part and needs to be replaced frequently. The current method of replacing the lifting rope of the excavator is to use the traditional mechanism to pass the steel wire rope of the auxiliary winding through the pulley bracket on the A-frame, and then pass through the machine shed to the small pulley in front of the lifting mechanism, and extend to the top pulley along the direction of the lifting rope , go down to the ground and tie the hoisting rope, then start the auxiliary winch to pull the hoisting rope to the hoisting drum. This method is more time-consuming and laborious, and the work is loaded down with trivial details. There are also users who pull the lifting rope to the big rope opening on the hangar ...
