Abstract
The utility model provides a portable engineering crane which is composed of a motor vehicle chassis, a steel cable stretching type lifting arm, a lifting winding engine, a lifting arm stretching winding engine, a rotary disc bracket of the lifting arm and a power drive device, wherein, the lifting winding engine and the lifting arm stretching winding engine are arranged on the right end of the steel cable stretching type lifting arm, which is simultaneously connected with the upper part of the rotary disc bracket of the lifting arm; the lower part of the rotary disc bracket of the lifting arm is connected with the motor vehicle chassis; the power drive device is arranged on the bottom of the motor vehicle chassis. The portable engineering crane has the advantages of reasonable design, simple structure, easy manufacturing, easy operation and use, strong maneuverability, broad application, etc.
Description
The utility model relates to a kind of engineering hanging device, specifically a kind of light engineering crane.
The various engineerings of prior art are complex structure, cost height, inefficiency etc. with the in use existing deficiency of the especially middle-size and small-size crane of lifting crane, the for example folding and unfolding of hoisting wirerope, the speed of the crane winch folding and unfolding steel rope of prior art is identical, the fast receipts with putting soon all will be finished by the rotating speed that improves driving engine, thereby make work efficiency reduce, increase the consumption of being clear oil or electric energy
The purpose of this utility model provides a kind of simple to operate, light engineering crane of increasing work efficiency, saving the energy.
The purpose of this utility model realizes in the following manner, the flywheel of the band ratchet of similar bicycle is set on the brake wheel of lifting winch and the flexible winch of lifting arm, the winch roller rotates with motor when hoisting heavy, when playing the weight whereabouts, can control the speed of the whereabouts of winch roller control weight by drg, on Power train, set up an electrical motor, the oil pump that is converted to by belt and belt pulley provides second kind of power except driving engine, it is adapted to is having electric field to close lifting construction down, and the driving engine for vehicle provides starting power when it is cold in the winter time.
Accompanying drawing 1 is the integral structure scheme drawing of light engineering crane;
Accompanying drawing 2 is the structural representation of light engineering crane lifting winch and the flexible winch of lifting arm;
Accompanying drawing 3 is a kind of structural representation of light engineering crane power drive;
Accompanying drawing 4 is looked closely structural representation for the big gear wheel of the flexible winch of light engineering crane lifting arm;
Accompanying drawing 5 is the structural representation of light engineering crane power drive.
Explain below with reference to Figure of description a kind of light engineering crane of the present utility model being done.
A kind of light engineering crane of the present utility model, its structure are to be stretched by motor-vehicle chassis 1, steel wire rope Formula lifting arm 2, lifting hoist engine 3, lifting arm flexible hoist engine 4, lifting arm support for rotary disc 5 and power Transmission device consists of, and lifting hoist engine 3, the flexible hoist engine 4 of lifting arm are arranged on the drawing lifting of steel wire rope The right-hand member of arm 2, the right-hand member while of the drawing lifting arm 2 of steel wire rope and the top phase of lifting arm support for rotary disc 5 Connect, the bottom of lifting arm support for rotary disc 5 and motor-vehicle chassis 1 join, and actuating unit is arranged on motor-driven The bottom of chassis 1.
