Abstract
The utility model provides an automobile crane turnover jack. The utility model has the structure characteristics that a hinge shaft is welded at the end part of a horizontal jack of a crane so that a vertical jack carries out the hinge shaft connection with the horizontal jack; an oil cylinder is arranged on the vertical jack; the piston rod of the oil cylinder is connected with the horizontal jack through wire ropes and is controlled to move by hydraulic pressure, and thus the vertical jack can automatically turn over upwards (or downwards); the maximum angle of turning over upwards can reach 180 DEG. Thereby, the distance between the vertical jack and the ground can be extended to the maximum, and the comfortableness of operating the crane and the road traffic capacity can be improved to a certain degree.
Description
Affiliated technical field
The utility model relates to a kind of car hosit supporting leg.
Background technology
The hoisting crane vertical leg overwhelming majority adopts fixing telescopic and a spot of swing formula at present.Fixedly telescopic leg does not possess the upset ability, and the ground Clearance is little, influences the crossing ability of hoisting crane to road; Swing formula supporting leg is finished by manpower, and labour intensity is big, influences the traveling comfort of crane operation.
The utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of car hosit supporting leg that possesses turn over function.
The technical scheme in the invention for solving the technical problem is: the axle that is fixedly hinged in the horizontal support legs end is hinged with vertical leg, fix an oil cylinder in the vertical leg outside, the oil cylinder piston bar is walked around roller by steel rope and is connected with horizontal support legs, roller shaft is fixed on the vertical leg, and the motion of piston rod is controlled by maneuvering valve.
Steel rope and oil cylinder piston bar are for being threaded, and the other end of steel rope is carved with horizontal support legs with rope by solid wire clips and is connected, and fixes with the steel rope adapter plate.
Be respectively arranged with baffle plate and postive stop baffle on vertical leg top and the horizontal support legs end face; During the hoisting crane hoisting operation, plug latch, and stretch out vertical leg, with leveling and supporting hoisting crane; When hoisting crane travels, handle vertical leg and upwards overturn 180 ° and by the postive stop baffle on the horizontal support legs with the baffle plate on the vertical leg is spacing fixes with latch.
The end face of jointed shaft is provided with the dead axle plate, in order to the axle that is fixedly hinged.
The retaining rope rod of joining weldering on the roller shaft can prevent coming off of steel rope.
The beneficial effects of the utility model are: 1, vertical leg can realize upset automatically by hydraulic actuated, and flip angle can reach 180 °, can strengthen vertical leg and ground-surface gap to greatest extent, and very big degree has improved the hoisting crane capacity of road.2, alleviate labour intensity, improved the traveling comfort of crane operation.
