Abstract

The invention discloses a wheel structure of horizontal jack, which belongs to the technical field of hoisting facility. The horizontal jack includes a jack body; the wheel structure includes a pair of back wheels, and a pair of front wheels; the wheel structure of horizontal jack is characterized in that the pair of front wheels includes a first trolley shelf, and a second trolley shelf, a first trolley and a second trolley as well as a shaft sleeve; the first trolley shelf and the second trolley shelf are mutually parallel; the fist trolley is arranged at one ends of the first trolley shelf, and the second trolley shelf in a rotating way, and is arranged between the first trolley shelf, and the second trolley shelf; the second trolley is arranged at the other ends of the first trolley shelf, and the second trolley shelf, and is arranged between the first trolley shelf, and the second trolley shelf; one end of the shaft sleeve is fixed with the middle part of the first trolley shelf, and the other end of the shaft sleeve is fixed with the middle part of the second trolley shelf; moreover, the shaft sleeve is sleeved at the shaft end of a trolley shaft, and is limited on the trolley shaft by a shaft nut. The technical scheme can pass through barriers during traveling, guarantee the jack to move stably, and prolong the service life of the jack.

Description

technical field [0001] The invention belongs to the technical field of lifting facilities, and in particular relates to a wheel structure of a horizontal jack. Background technique [0002] Chinese invention patent application publication number CN101028914A has introduced a kind of jack wheel with shock-absorbing device, respectively disposes the shock-absorbing device that is made of straight shaft, compression spring and axle sleeve on the rear wheel support of a pair of rear wheels, this patent application scheme Compared with the prior art, it can objectively reflect the technical effects mentioned in lines 8-15 on page 2 of the description. But although the jack wheel of this structure can improve the landing effect of the wheel, that is to say, the four wheels of the jack body are kept in good contact with the ground, but it cannot achieve the effect of stably surmounting obstacles. As known to those skilled in the art, in a vehicle repair place, in order to prevent ...
