Embodiment 1

[0035] see Figure 1 to Figure 4 As shown, the lifting counterweight provided by the present application is used for a crane, and the lifting counterweight includes a connecting rope 101, a movable counterweight 102 and a fixed counterweight 111; one end of the connecting rope 101 is connected with the reel 103 of the crane, and the connecting rope 101 The other end is connected with the movable counterweight 102 , and the reel 103 rotates to drive the connecting rope 101 to lift, so that the connecting rope 101 pulls the movable counterweight 102 close to or away from the fixed counterweight 111 .

[0036] The counterweight of the crane mainly plays a role in maintaining the balance of the car body. For some large-tonnage cranes, in addition to being equipped with fixed counterweights 111, movable counterweights 102 also need to be added. The liftable counterweight provided by the present application promotes the movable counterweight 102 by setting the connecting rope 101, ...

Embodiment 2

[0046] The liftable counterweight in the second embodiment is an improvement on the basis of the above embodiment. The technical content disclosed in the above embodiment will not be described repeatedly, and the content disclosed in the above embodiment also belongs to the content disclosed in the second embodiment.

[0047] see Figure 1 to Figure 4 As shown, in the optional solution of this embodiment, when the volume of the fixed counterweight 111 is too large, the connecting rope 101 connected with the reel 103 and the movable counterweight 102 needs to pass through the fixed counterweight 111. A through hole 112 is opened on the counterweight 111 , so that the connecting rope 101 can pass through the through hole 112 to be connected with the movable counterweight 102 .

[0048] It should be noted that the number and positions of the through holes 112 and the number and positions of the connecting ropes 101 need to be opened correspondingly.

[0049] In the optional solu...

Embodiment 3

[0052] Embodiment 3 of the present application provides a crane, which includes the liftable counterweight of any one of the above embodiments, and thus has all the beneficial technical effects of the liftable counterweight of any one of the above embodiments, which will not be repeated here.

Abstract

The invention relates to the technical field of mechanical equipment, in particular to a lifting counterweight and a crane. The lifting counterweight is used in the crane. The lifting counterweight comprises a connecting rope and a movable counterweight; one end of the connecting rope is connected with a drum of the crane, the other end of the connecting rope is connected with the movable counterweight, and the drum is rotated to drive the connecting rope to move, so that the connecting rope pulls the movable counterweight to be raised or lowered. The lifting counterweight drives the movable counterweight to be raised by the connecting rope. The device has a simple structure and low cost, and solves the problem of non-synchronization in a way of using an oil cylinder to drive the movable counterweight.

Description

technical field [0001] The present application relates to the technical field of mechanical equipment, in particular to a lifting counterweight and a crane. Background technique [0002] In the prior art, the truck crane lifts the movable counterweight by jacking or hoisting with multiple oil cylinders, the production cost is high, and there is a problem of asynchronous operation of the multiple oil cylinders during the lifting process. Contents of the invention [0003] The purpose of this application is to provide a lifting counterweight and a crane for lifting movable counterweights. [0004] The application provides a liftable counterweight for a crane, the liftable counterweight includes a connecting rope and a movable counterweight; [0005] One end of the connecting rope is connected to the reel of the crane, the other end of the connecting rope is connected to the movable counterweight, and the reel rotates to drive the moving of the connecting rope so that the co...
