Description
Technical field
The utility model relates to a kind of elevator machinery, especially a kind of crane-car.
Background technology
Crane-car in the market mainly contains the 10 multiclass products from the different tonnage of 8t mono-160t.Along with improving constantly of technical merit, product tonnage is also towards more large-tonnage future development.Crane-car can be widely used in hoisting operation under the operating modes such as industrial and mining enterprises, building ground, port and pier, oil field, railway, warehouse and goods yard and lifting work.
Existing crane-car is made up of chassis and hoisting operation part two large divisions, and chassis has wheel, and corner, chassis place is to having supporting leg, and front portion, chassis is provided with the headstock for drawing chassis; Chassis is provided with hoisting operation part, hoisting operation part comprise winch, telescoping boom, for top lifting and the oil cylinder of support telescopic arm and telescopic plunger thereof, fixed pulley assembly, movable pulley component and the suspension hook that is arranged on movable pulley component.
Existing crane-car is through being usually used in salvaging weight under water.Because weight often has uncertain weight under water, and load can increase (losing the buoyancy of water to it during weight water outlet) when weight water outlet, therefore higher to the requirement of strength of crane-car telescoping boom.
For the restriction of interior space, and obtain the consideration of larger arm angle of elevation, the oil cylinder of existing crane-car and telescopic plunger thereof are generally all located at front portion, chassis, and the front portion of telescopic plunger and telescoping boom is hinged.Such setting, extend the arm of force (fixed pulley assembly is to telescopic plunger and the anterior hinge-point distance of telescoping boom) during hoisting heavy, making arm bear larger moment when lifting by crane the object of unit weight, the requirement of strength of arm being improved greatly, also shortens the service life of arm.
In addition, lift by crane under water weight time need the metal binding wire rope of hook colligation weight.During operation at night, on-the-spot lighting fixture throws light in space on a large scale to scene.Because weight position is lower, this place's light other place more on-the-spot is comparatively dim, and staff not easily promptly makes hook metal binding wire rope.Using search lamp according to the steel rope place of colligation weight, be not easily aim on the one hand, extend the operating time, is that searchlighting light is easily blocked by field operation personnel, equipment etc. on the other hand, needs to carry out complicated cooperating.
Utility model content
The purpose of this utility model is to solve deficiency of the prior art, provides a kind of crane-car lower to the requirement of strength of arm.
For achieving the above object, high strength crane-car of the present utility model, comprise chassis and be located at the hoisting operation part on chassis, chassis has wheel, and corner, chassis place is to having telescopic outrigger, and front, chassis is provided with the headstock for drawing chassis;
Chassis is provided with hoisting operation part, hoisting operation part comprise be located at winch on chassis and brace table, front end be hinged on telescoping boom on brace table, for top lifting and the oil cylinder of support telescopic arm and telescopic plunger thereof, the fixed pulley assembly being installed on telescoping boom rear end, the suspension hook that is suspended to the movable pulley component below fixed pulley assembly by hoist rope and is arranged on movable pulley component;
Winch be positioned at telescoping boom front and lower than the hinge-point of telescoping boom and brace table; The front top of telescoping boom is provided with deflection sheave; Winch traction described hoist rope walk around deflection sheave after along telescoping boom extend to fixed pulley assembly and walk around fixed pulley assembly backward under walk around described movable pulley component;
The top of described telescopic plunger and the front portion of described telescoping boom are hinged; Described chassis is provided with hydraulic prop, the postmedian of telescoping boom described in the apical support of hydraulic prop.
