Abstract

The utility model relates to a balance device for preventing a bracket of a grab bucket roller with a single beam from being slanted. The balance device comprises five parts, namely, a rolling wheel track (2), a rolling wheel (3), a pin (4), gaskets (5) and a steel channel (6). The balance device is characterized in that the rolling wheel track (2) is welded on the sloping edge at the side of a single beam track (1); the pin (4) is inserted into the rolling wheel (3) and is welded with one end of the steel channel (6); the two gaskets (5) are respectively positioned at two sides of the pin (4); the other end of the steel channel (6) is welded on the bracket of the grab bucket roller (8). When the balance device works, the only requirement is to periodically check whether the rolling wheel is abraded; if the rolling wheel is abraded, the rolling wheel is replaced by taking out the pin, so that the rolling wheel in later use is convenient to replace. Thus, the normal operation of a travelling crane is ensured and the maintenance time is saved.

Description

A kind of balancing device that prevents that single-beam grab bucket rolling stand from tilting

Technical field

The utility model is a kind of balancing device that prevents that single-beam grab bucket rolling stand from tilting.

Background technology

Electric single-beam grab crane will be transported to assigned address after material grasping, in operational process, wheeling mechanism drive rolling stand be expert on car owner's beam before and after walking, because main rope roll barrel and secondary steel rope roll barrel are arranged on rolling stand, grab bucket is to drive operation with main rope and secondary steel rope, driving girder is when left and right and front and back walking, grab bucket can produce and swing, rolling stand meeting wigwag motion, when grab bucket amplitude of fluctuation is large, the original balancing device of rolling stand lost efficacy, and rolling stand is tilted, thereby make major-minor steel rope in cylinder one side kink, grab bucket cannot rise out and open and close.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming that above-mentioned prior art exists, and proposes a kind of balancing device that prevents that single-beam grab bucket rolling stand from tilting.

A kind of balancing device that prevents that single-beam grab bucket rolling stand from tilting, comprise: roller track, roller, pin, pad, five parts of channel-section steel, it is characterized in that: roller track is welded in single-beam rail side hypotenuse position, pin inserts in roller and one end of pin and channel-section steel is welded, a pad is respectively placed on pin both sides, and the channel-section steel other end is welded on grab bucket rolling stand.

Three cover balancing devices are respectively installed in car owner's beam both sides of being expert at, in the middle of rolling stand and both sides respectively install a set of.

Install six cover balancing devices, grab bucket is when driving operation, when the swing producing causes rolling stand to rock, balancing device is just played a supporting role, roller on balancing device all can be walked on roller track, to guarantee that wheeling mechanism drives rolling stand, major-minor steel rope roll barrel to be in operation and can not produce to lopsidedness by wigwag motion, cause major-minor groove skipping of steel rope while also just can not clench.

The utility model has the advantage of: only need regularly go to check whether roller weares and teares, if any wearing and tearing, take out pin and change roller, replacing so is later also very convenient, thereby guarantees the normal operation of driving and save maintenance time.

The specific embodiment

Install after balancing device, grab bucket is when driving operation, when the swing producing causes rolling stand to rock, balancing device is just played a supporting role, roller on balancing device all can be walked on roller track, to guarantee that wheeling mechanism drives rolling stand, major-minor steel rope roll barrel to be in operation and can not produce to lopsidedness by wigwag motion, cause major-minor groove skipping of steel rope while also just can not clench.

Claims

1. a balancing device that prevents that single-beam grab bucket rolling stand from tilting, comprise: roller track (2), roller (3), pin (4), pad (5), (6) five parts of channel-section steel, it is characterized in that: roller track (2) is welded in position, single-beam track (1) skew back limit, pin (4) inserts in roller (3) and by pin (4) and one end of channel-section steel (6) and welds, a pad (5) is respectively placed on pin (4) both sides, and channel-section steel (6) other end is welded on grab bucket cylinder (8) support.
