Description
Technical field
The utility model belongs to lifting technique field, particularly relates to the portable counter weight device of a kind of car hosit.
Background technology
Counterweight is the vitals of crane, and the design of counterweight directly has influence on the lifting performance of crane.The mounting means difference of counterweight directly has influence on lifting performance and the work efficiency of car load.At present, the counterweight of crane has two kinds of mounting meanss, and a kind of is the rear portion adopting fastener to be directly fixed on the turntable of crane, and another kind is the mounting means adopting hydraulic oil cylinder driving counterweight to rotate.
The feature of fixed weight is: adopt bolt or other fasteners counterweight to be installed on the rear portion of truck crane turntable.According to the size adjustment of hoisting capacity and the distance of turntable center, cannot cannot rotate along with turntable in the place of narrow space in addition, and then the operating range of hoisting crane can be affected.Although technical risk is little, cost is lower to adopt the hoisting crane of hydraulic oil cylinder driving counterweight to exist, there is many defects such as cannot adjusting counterweight according to hoisting capacity, vehicle cannot work at small space, hoisting crane adjustment counterweight efficiency is low.
Utility model content
The utility model, in order to solve weak point of the prior art, provides that a kind of compact conformation, counterweight change speed are fast, the portable counter weight device of car hosit of good stability.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: the portable counter weight device of car hosit, comprise the horizontal telescoping oil cylinder being located at turntable rear end and the horizontal slide be located on the downside of turntable rear portion, clump weight is slidably connected in horizontal slide, turntable is provided with Connection Block, the cylinder body of horizontal telescoping oil cylinder is hinged on Connection Block, and clump weight is provided with bearing, and the piston rod of horizontal telescoping oil cylinder is hinged on bearing;
Described horizontal slide is respectively equipped with one with right side on the left of turntable, row's nylon back-up block is provided with all along its length in each horizontal slide, a bearing is respectively equipped with between adjacent two nylon back-up blocks, the central axis of bearing is arranged, the height of bearing is lower than the height of nylon back-up block, on the left of clump weight and right side be respectively equipped with one piece extend into left side be horizontal slide and right side horizontal slide in guide plate, guide plate lower surface contacts with nylon back-up block upper surface, bearing touch is arranged in one of clump weight left-hand face and left side, bearing touch is arranged on one of clump weight right lateral surface and right side.
The brace panel being inverted L shape by cross-sectional plane between described guide plate upper surface and clump weight lateral surface connects.
Adopt technique scheme, alternately nylon back-up block and bearing is arranged in the mutual road of level that turntable both sides are arranged, during self-balanced upper rotary, the gravity of clump weight is supported by nylon back-up block, nylon back-up block friction drag is little, and two row's bearings are mainly used in preventing self-balanced upper rotary telescopic process from shake and crooked phenomenon occurring.Horizontal telescoping oil cylinder according to the position of the flexible adjustment clump weight of piston rod, to adapt to the goods lifting Different Weight size.
In sum, the utility model has following beneficial effect:
1, counterweight change speed is fast: compared with adopting the hoisting crane of fixing clump weight, and owing to adopting horizontal telescoping oil cylinder to promote clump weight, compared with the mode of manual working, clump weight change speed is fast;
2, good stability: clump weight of the present utility model adopts the mounting means of nylon back-up block sliding support and the spacing guiding of bearing, and the crane stability comparing fixed weight increases to some extent;
3, practicality is good: because the utility model adopts single hydraulic oil cylinder driving, and compared with adopting the hoisting crane of fixed weight, although cost of product is high, structure is simple, economical and practical;
4, good looking appearance: the horizontal telescoping oil cylinder, bearing pin etc. of self-balanced upper rotary are all arranged at box house, and all cannot see under work, motoring condition, outward appearance is very attractive in appearance.
