Abstract
The utility model discloses a detachable inner package type supporting leg for hoisting machinery. The detachable inner package type supporting leg comprises an outer supporting leg and an inner package supporting leg, and is characterized in that the outer supporting leg is fixed on a horizontal telescopic supporting leg through a bolt; the inner package supporting leg consists of a supporting leg cylinder and an inner supporting leg frame; the head of a piston rod of the supporting leg cylinder is hinged to the inner package supporting leg; the other end of the supporting leg cylinder is hinged to the horizontal telescopic supporting leg; and the inner supporting leg frame is always coated on the supporting leg cylinder and can stretch and retract in the outer supporting leg. Because the defects that the supporting leg frames at two sides of a common H-shaped supporting leg of the conventional lorry-mounted crane cannot be detached, the occupied space is large, inconvenience is brought to package transport and maintenance of the crane supporting leg and the like are overcome, so that the supporting leg cylinder of the lorry-mounted crane is always hidden in the inner supporting leg frame, and the inner supporting leg frame can stretch and retract in the outer supporting leg frame, so that the supporting leg cylinder of the lorry-mounted crane has high adaptability, the influence of the external environment can be reduced, the stability of the supporting leg cylinder is improved, and the service life is prolonged.
Description
Technical field
The utility model is a kind of detachable enwraped type supporting leg of elevator machinery, belongs to the technical field of elevator machinery.
Background technology
The weight-lifting equipment such as lorry-mounted crane, car hosit all is equipped with supporting leg.Its Main Function is by increasing the support interval of hoisting crane support. improve stability and the hoisting capacity of hoisting crane.At present, on elevator machinery there be common supporting leg pattern: moth formula, H type, x type, radiant type, dumpling connect several supporting legs of formula.Lorry-mounted crane generally adopts H type supporting leg form, but this kind supporting leg is not fine for the car load comformability, and some support oil cylinders are directly outside exposed, affect stability and service life, if the vertical leg part is non-dismountable, delivery transportation and maintenance are all extremely inconvenient.
Summary of the invention
For overcoming the defects of the existing supporting leg of elevator machinery, the purpose of this utility model is that a kind of detachable enwraped type supporting leg for elevator machinery will be provided.
For solving its technical matters, the technical scheme that the utility model adopts is: the detachable enwraped type supporting leg of the elevator machinery of designing includes: outer supporting leg and Nei Bao supporting leg, its feature is: outer supporting leg is bolted on the horizontal extension supporting leg, interior bag supporting leg is comprised of support oil cylinder and interior supporting leg frame, the piston rod head end of support oil cylinder is hinged on interior bag supporting leg, the other end of support oil cylinder is hinged on the horizontal extension supporting leg, interior supporting leg frame is coated on support oil cylinder all the time, and flexible withdrawal the in supporting leg outside.
The beneficial effects of the utility model are: because the utility model has adopted such scheme, the lorry-mounted crane support oil cylinder is hidden in interior supporting leg frame all the time, and stretch out retraction in the supporting leg frame outside, has good comformability with this this lorry-mounted crane support oil cylinder, can reduce the impact that is subject to external environment condition, increase the stability of support oil cylinder, extend its service life; Overcome the H type supporting leg that lorry-mounted crane in the past generally adopts, two side leg frames of existence are non-dismountable, take up room large, give the defectives such as crane support packing and transporting and maintenance bring inconvenience, and have reached the purpose of this utility model.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated;
Fig. 1 is structural representation of the present utility model.
