Description
Technical field
The utility model relates to the technical field of Mobile hoisting crane, particularly a kind of counter weight device of mobile lifting crane.
Background technology
Lifting crane is when reaching maximum lifting weight, and lifting scope is less, or when lifting scope reaches maximum, lifting weight is less, causes lifting work limited.As some super-large components lift time, common lifting crane often cannot complete, and not in tower crane boundary of works area, and often need from ultra-large type weight-lifting equipment finishing equipment liftings such as coastal cities allotment gauntrys crane, economy is poor.
Utility model content
In order to solve the deficiency of above-mentioned prior art, the purpose of this utility model is: provide a kind of and provide the moment contrary with hoisting moment by hydraulic stem and counterweight, reaches the counter weight device that the object increasing lifting scope and lifting weight moves lifting crane.
Invention thought of the present utility model is: by increasing hydraulic actuating cylinder and counterweight basket on rear side of wheel crane, when applying counterweight, do not destroying under pivoting support and resistance to overturning prerequisite, the moment that one contrary with during hoisting operation is provided, increase hoisting moment, thus increase maximum lifting weight and the lifting scope of lifting crane.
A counter weight device for mobile lifting crane, comprise car body, be arranged on pivoting support on car body and the weight-lifting equipment hinged with pivoting support, described weight-lifting equipment rear portion is provided with hydraulic actuating cylinder, described hydraulic actuating cylinder is provided with counterweight basket.
The plunger end of described hydraulic actuating cylinder is fixedly connected with counterweight basket, is provided with strut bar bottom described counterweight basket.
Described strut bar and described counterweight basket hinged.
The utility model adds two cover Weighting systems in vehicle-mounted weight-lifting equipment bottom symmetry, often overlaps and is made up of the piston rod of high rigidity hydraulic actuating cylinder and counterweight basket, and each counterweight in the key Fang Yousi props up hydraulic supporting strut.When carrying out hoisting operation, the piston rod of hydraulic actuating cylinder stretches out backward, and is opened by the hydraulic supporting strut that counterweight is square in the key, support, in alleviation interpolation counterweight process, impact kinetic energy is to the damage of piston rod, then according to lifting weight, calculate required counterweight, and counterweight is put into counterweight basket.When interpolation counterweight is complete, when need carry out hoisting operation, the hydraulic supporting strut bottom counterweight basket is packed up.
Described car body rear end sweep upper surface is provided with guide rail, and the direction of described guide rail is parallel with described car body longeron.
The piston rod of described hydraulic actuating cylinder is connected with counterweight basket, bottom described counterweight basket, is provided with pulley.
Described pulley is arranged in described guide rail.
The plunger end of described hydraulic actuating cylinder is fixedly connected with headstock.
Hauling rope is provided with between described counterweight basket and described headstock.
Fixed weight basket is changed into the increase effect that portable counterweight also can realize lifting crane hoisting moment.Headstock is increased, for providing power for portable counterweight basket at piston-rod end.When piston rod stretches out backward, headstock is in relaxed state, and now portable counterweight basket is not subjected to displacement, and when piston rod is to Len req, starts headstock, portable clump weight is moved to hydraulic actuating cylinder rear end under the traction of steel strand rope.Be friction of rolling in portable counterweight basket moving process and between car body and piston rod, car body arrange guide rail, to reduce friction force.
By test, the beneficial effects of the utility model are: provide the moment contrary with hoisting moment by hydraulic actuating cylinder and counterweight, reach the object increasing lifting scope and lifting weight.Four hydraulic supporting struts bottom each counterweight basket, to prevent in interpolation counterweight process impact kinetic energy to the damage of hydraulic cylinder piston rod.

Detailed description of the invention
In order to the technical characterstic of this programme can be clearly demonstrated, below by detailed description of the invention, this programme is set forth.
Embodiment 1
See Fig. 1, Fig. 2, the utility model is a kind of counter weight device of mobile lifting crane, comprises car body 1, is arranged on pivoting support 2 on car body 1 and the weight-lifting equipment 3 hinged with pivoting support 2, weight-lifting equipment 3 rear portion is provided with hydraulic actuating cylinder 4, hydraulic actuating cylinder 4 is provided with counterweight basket 5.The plunger end of hydraulic actuating cylinder 4 is fixedly connected with counterweight basket 5, is provided with strut bar 6 bottom counterweight basket 5.Strut bar 6 is hinged with counterweight basket 5.
In vehicle-mounted weight-lifting equipment 3 bottom, symmetry adds two cover Weighting systems, often overlaps and is made up of high rigidity hydraulic actuating cylinder 4 and counterweight basket 5, has four hydraulic supporting struts 6 below each counterweight basket 5.When carrying out hoisting operation, the piston rod of hydraulic actuating cylinder 4 stretches out backward, and is opened by the hydraulic supporting strut 6 below counterweight basket 5, support, in alleviation interpolation counterweight process, impact kinetic energy is to the damage of piston rod, then according to lifting weight, calculate required counterweight, and counterweight is put into counterweight basket 5.When interpolation counterweight is complete, when need carry out hoisting operation, the hydraulic supporting strut 6 bottom counterweight basket 5 is packed up.
Embodiment 2
See Fig. 4, Fig. 5, the utility model is a kind of counter weight device of mobile lifting crane, comprises car body 1, is arranged on pivoting support 2 on car body 1 and the weight-lifting equipment 3 hinged with pivoting support 2, weight-lifting equipment 3 rear portion is provided with hydraulic actuating cylinder 4, hydraulic actuating cylinder 4 is provided with counterweight basket 5.Car body 1 rear end sweep upper surface is provided with guide rail 7, and the direction of guide rail 7 is parallel with car body 1 longeron.The piston rod of hydraulic actuating cylinder 4 is connected with counterweight basket 5, bottom counterweight basket 5, is provided with pulley.Pulley is arranged in guide rail 7.The plunger end of hydraulic actuating cylinder 4 is fixedly connected with headstock 8.Hauling rope 9 is provided with between counterweight basket 5 and headstock 8.
