Abstract
The utility model discloses a balance trolley for a crane, which comprises a trolley, wherein a plurality of grooves are formed in the left side and the right side of the trolley, a cylinder mounting seat is arranged in each groove, a cylinder is mounted on each cylinder mounting seat, a screw sleeve is arranged at the working end of the cylinder, and a movable support rod is sleeved in each screw sleeve; the lower end of the movable supporting rod is provided with a ground foot, and the upper end of the movable supporting rod is provided with a rotating device. The utility model discloses a simple structure can guarantee the equilibrium of dolly according to different working conditions, potential safety hazard when reducing the hoist and using.
Description
Technical Field
The utility model relates to a hoist field especially relates to a balance car for hoist.
Background
The hoist is as one of the important equipment of transport goods, and at the in-process of in-service use, some service environment probably have the uneven condition in ground, in order to improve the result of use, reduce the potential safety hazard problem that the hoist is uneven and bring, need increase a balance car to the hoist.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a balance car for hoist solves the unbalanced problem that brings among the hoist service environment.
In order to solve the technical problem, the utility model adopts the following technical scheme:
the utility model relates to a balance trolley for crane, including the dolly, a plurality of recess has all been seted up to the dolly left and right sides, be provided with the cylinder mount pad in the recess, the cylinder mount pad is installed the cylinder, the working end of cylinder is provided with the swivel nut, the swivel nut endotheca is equipped with the removal branch; the lower end of the movable supporting rod is provided with a ground foot, and the upper end of the movable supporting rod is provided with a rotating device.
Furthermore, a plurality of wheels are symmetrically arranged at the bottom of the trolley.
Furthermore, the upper end of the trolley is provided with a mounting seat.
Furthermore, the movable support rod is provided with an external thread in threaded connection with the threaded sleeve.
Furthermore, the specific number of the grooves is four, and the grooves are symmetrically arranged on the side wall of the trolley.
Compared with the prior art, the utility model discloses a beneficial technological effect:
the utility model discloses a balance car for hoist is through starting the cylinder, with the swivel nut push away from the dolly lateral wall on, later rotatory rotary device makes removal branch downstream, falls subaerially until the lower margin, play the effect of supporting the dolly can, in addition, different according to actual operational environment, the ground height difference promptly, four removal branches can select different rotation height according to actual conditions. When the crane does not need to work, the rotating device is rotated reversely to enable the movable support rod to move upwards, and the ground feet are retracted; then, the cylinder is started, so that the threaded sleeve is close to the trolley, and the trolley is convenient to move. In a word, this utility model structure is simple, can guarantee the equilibrium of dolly according to different behavior, potential safety hazard when reducing the hoist and using.

Detailed Description
As shown in fig. 1-3, a balance trolley for a crane comprises a trolley 1, wherein a plurality of wheels 2 are symmetrically installed at the bottom of the trolley 1, and in this embodiment, the number of the wheels 2 is four. And the upper end of the trolley 1 is provided with a mounting seat 3 for mounting a crane.
The trolley is characterized in that a plurality of grooves 10 are formed in the left side and the right side of the trolley 1, the number of the grooves 10 is four, and the grooves are symmetrically formed in the side wall of the trolley 1. Install cylinder mount pad 9 in the recess 10, cylinder 8 is installed to cylinder mount pad 9, the work end of cylinder 8 is provided with swivel nut 5, has seted up the internal thread in the swivel nut 5. The movable support rod 6 is sleeved in the threaded sleeve 5, an external thread connected with the threaded sleeve 5 is arranged on the movable support rod 6, and the movable support rod 6 rotates in the threaded sleeve 5 to move up and down. The lower end of the movable support rod 6 is provided with a foot margin 4 for supporting the trolley structure; the upper end is provided with a rotating device 7 for rotating the rotating device 7.
The action process of the utility model is as follows:
firstly, starting the air cylinder 8, and keeping the screw sleeve 5 away from the trolley 1; then, the rotating device 7 is rotated, so that the ground feet 4 reach the ground, the function of supporting the trolley 1 is achieved, and the balance type of the crane trolley is guaranteed; finally, when the crane is not needed, the rotating device 7 is rotated again, so that the anchor 4 is retracted, the air cylinder 8 is started, and the screw sleeve 5 is retracted.
The above-mentioned embodiments are only intended to describe the preferred embodiments of the present invention, but not to limit the scope of the present invention, and those skilled in the art should also be able to make various modifications and improvements to the technical solution of the present invention without departing from the spirit of the present invention, and all such modifications and improvements are intended to fall within the scope of the present invention as defined in the appended claims.
