Abstract
A side clearance adjuster of an elevator boom consists of a holding bolt, a screw thread seat, a sliding block, a bolt and a cut. The sliding block is fixed at one end of the screw thread seat by the bolt. The screw thread seat is provided with the cut and the other end of the screw thread seat is provided with the holding bolt. As adopting the structure, the utility model has the advantages of simple structure and convenient adjusting and assembly. The utility model not only adjusts the clearance, but also is beneficial to reducing the friction during the stretching of the elevator boom. The adjuster adjusts the clearance through screw thread and can realize stepless adjustment.
Description
Technical field
The utility model relates to a kind of backlash setting device that is used for the crane telescopic boom.
Background technology
Crane arm is owing to be the heavy in section plate and shell structure, it all can produce manufacturing errors in bending and forming and welding process, the cylindrical shell accuracy of manufacture far can not guarantee the job requirement of telescopic boom, when crane arm when stretching the state loaded work piece entirely, although the afterbody side of every joint crane arm is provided with big slide block, but sometimes because the bad lateral adjustment slide block that is provided with of head of reasons in structure arm, only depend on arm head portion top shoe to carry out lateral adjustment, sometimes be difficult to adjust to the right place, if sideshake is too big between the at this moment interior acromere arm, certainly lead to the side sway phenomenon.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, easy to adjust, crane arm backlash setting device that can carry out stepless adjustment.
The purpose of this utility model is achieved in that by tight fixed bolt, threaded block, slide block, screw, otch to be formed, and screw is fixed on threaded block one end with slide block, has otch on the threaded block, and the other end of threaded block is equipped with tight fixed bolt.
Because the utility model adopts said structure, and is simple in structure, adjust, easy to assembly, not only to adjust the gap but also helped reducing the friction force of crane arm when flexible, electrodeless adjusting can be realized by threaded adjusting in this device adjusting play.
Description of drawings
Fig. 1 is a constructional drawing of the present utility model.
Fig. 2 is the left view of Fig. 1.
1 tight fixed bolt, 2 threaded blocks, 3 slide blocks, 4 screws, 5 otch among the figure.
The specific embodiment
Embodiment: form by tight fixed bolt 1, threaded block 2, slide block 3, screw 4, otch 5, screw 4 is fixed on threaded block 2 one ends with slide block 3, have otch 5 on the threaded block 2, the other end of threaded block 2 is equipped with tight fixed bolt 1, along with tightening of tight fixed bolt 1, otch 5 opening degrees on the threaded block 2 can change.When the backlash of acromere arm and internal segment arm excessive, when causing the crane arm side sway, can tighten setting device, make the gap of slide block 3 and internal segment arm in the threaded block 2 reach designing requirement, tighten the tight fixed bolt 1 on the setting device then, along with tightening of tight fixed bolt 1, otch 5 opening degrees on the threaded block 2 can diminish, outside thread on the threaded block 2 just and the negative thread interlock on the acromere arm bearing like this, thereby whole setting device is fixed, the slide block 3 of plastics is set, has not only adjusted the gap but also helped reducing the friction force of crane arm when flexible, this apparatus structure is simple, adjust, easy to assembly, electrodeless adjusting can be realized by threaded adjusting in the adjusting play, regulates more superior than shimming.
