Fixing and adjusting mechanism for sliding blocks of telescopic booms

Abstract

The invention discloses a fixing and adjusting mechanism for sliding blocks of telescopic booms, and belongs to the technical field of telescopic booms of engineering machines. The fixing and adjusting mechanism for the sliding blocks of the telescopic booms comprises the hollow outer boom and the inner boom, wherein a groove is formed in the upper end of the inner boom, a through hole is formed in the lower end of the outer boom, and the sliding blocks are mounted in the groove and the through hole correspondingly; the guiding surface of the sliding block on the inner boom is inlaid in the groove of the inner boom, the guiding surface of the sliding block on the outer boom is inlaid in the through hole of the outer boom, and the supporting surfaces of the sliding blocks are located between the inner wall of the outer boom and the outer wall of the inner boom; and at least two sealing plates are fixed outside the through hole of the outer boom in a sealing mode, and fastening devices are mounted in the sealing plates. According to the fixing and adjusting mechanism for the sliding blocks of the telescopic booms, a mounting and gap adjustment structure for the sliding blocks is improved, the maintenance efficiency of a gap of a supporting frame by a user is greatly improved, the labor intensity is relieved, and the cost is reduced; overall operation is easy, safe, reliable and easy to realize; and the fixing and adjusting mechanism is suitable for most engineering machines provided with telescopic boom structures or product equipment of other types and wide in application range.

Description

technical field [0001] The invention relates to the technical field of construction machinery telescopic arms, in particular to a mechanism for fixing and adjusting sliders of a telescopic arm frame. Background technique [0002] At present, a variety of construction machinery and equipment with similar telescopic boom structures are used in all walks of life. Nylon sliders are an indispensable part of these telescopic boom structures, which play a role in supporting and improving sliding efficiency. With the increase in the frequency of use of the telescopic boom structure of the equipment, the wear of the nylon slider is intensified, and the gap between the relative moving parts of the telescopic boom structure will increase, and the increase in the gap will cause certain harm to the normal use of the equipment. [0003] Adjusting the gap or replacing a new slider is an essential work in the maintenance process of the telescopic boom structure. For example, the sliders on...

Problems solved by technology

For example, the sliders on the support frame of the backhoe loader (similar in structure to the telescopic boom) are fixed by bolts. One slider uses two bolts, and there are 32 bolts in the 16 sliders of the whole vehicle. It is very troublesome to install and disassemble.

In addition, a number of adjusting shims with different thicknesses are installed between the slider and the support frame to adjust the gap between the inner and outer support frames due to the wear of the slider. The installation and removal of the adjustment shims is also quite cumbersome. There are also varying degrees of complaints from workers in the factory, which greatly reduces the efficiency of product maintenance
