Abstract
The utility model relates to a counter balance part of the construction crane, and the aim is to provide an improved counter balance structure. The utility model uses the lever principle as the theoretical basis and is formed by the combination of the prior art. According to the present situation of the crane counter balance, the stationary type counter balance alters to the telescopic counter balance, which improves the structural property of the hydraulic cranes, and which has a positive effect on the lifting ability and the work efficiency.
Description
The utility model relates to the counter weight construction of the counterweight part of crane, particularly hydraulic truck crane.
The counterweight part of hydraulic truck crane is the fixed type counterweight.The rear portion of it and crane arm support joins, and becomes vertical counterweight with crane arm.But utilize the lever principle analysis just as can be seen, the distance of its balance weight body and centre of gration, promptly the distance of force and fulcrum is too short, and the distance between fulcrum and the pendulum point is long, so, be difficult to keep balance.Therefore when lifting, particularly under big swinging radius during lifting, its counterweight effect is far from suitable.
The purpose of this utility model is that a kind of improved counter weight construction will be provided.It not only can play the general counterweight effect of existing type fixed type counterweight, but also can give corresponding counterweight according to the force-bearing situation of crane arm.
The implementation method of the telescopic counterweight that the utility model proposes is such: in the both sides of crane arm support, install two telescopic weight arms, two arm axle lines are parallel to each other to a plane, and the minor details tail end of balance weight body and weight arm joins, by hydraulic efficiency gear transmission, retractable.
The job procedure of telescopic counter weight construction is by the automatic-balancing system automatic guidance.It can be according to relevant datas such as the hoisting capacity of crane arm part and swinging radiuss, makes two telescopic weight arms as promoting counterweight, balance weight body backward level push away and stretch, until reaching corresponding counterweight effect, work finishes it is regained original position.
The counterweight form of telescopic counter weight construction is four necessary conditions according to lever balance, proposes at the counterweight present situation of hoisting crane.Wherein providing of telescopic weight arm used this method of prolongation lever moving arm and realized.Its advantage is to have utilized the telescopicing performance of prior art, particularly weight arm again, and actv. has overcome the non-equilibrium state between lifting and the counterweight.For realizing the remote counterweight of balance weight body, played certain positive role.
The utility model is to be theoretical basis with the lever principle, and the design plan that forms in conjunction with the characteristics of prior art.When it has possessed capable of expansion and contraction, Nover practical, possessed also that realize may by the balanced system automatically controlled.Because telescopic counter weight construction is a kind of new counterweight form, directly applies to existing type hydraulic truck crane and is far from suitable.So the point of view of the present utility model not only is to obtain corresponding balance, but other structure cooperatively interact and coadapted prerequisite under, by its equilibrium activity, impel the aspect such as structural behaviour, load-carrying ability, work efficiency of hydraulic lift to be further improved.
Concrete structure of the present utility model and mode of operation are provided by the following drawings:
Fig. 1 is the birds-eye view that provides according to the telescopic counter weight construction that the utility model proposes.
Describe in detail according to concrete structure and the part details that the utility model proposes below in conjunction with Fig. 1.
This structure comprises a balance weight body (1), two telescopic weight arms (2), (3), and main portions such as two groups of hydraulic rams (7), (8) are formed.Telescopic weight arm (2), (3) become half telescopic location among the figure.
Two telescopic weight arms (2), (3) are made by high strength steel, are made up of more piece, and its cross section becomes the rectangular box cross section.Wherein fundamental segment (first segment) is a fixed knot, and they are separately fixed at two side plates (5), (6) both sides of crane arm support.Balance weight body (1) is the cast iron solid, is fixed on the minor details tail end of slip joint.Hydraulic ram (7), (8) are two groups, are installed in respectively in the empty stomach of two telescopic weight arms (2), (3).Along direction shown in the arrow (9), stretch out under the effect of hydraulic ram (7), (8) backward synchronously two telescopic weight arms (2), (3).Two weight arms (2), (3) become cantilever position at this moment.According to different situations and field of application, can make telescopic weight arm (2), (3) horizontal stretching backward, but also luffing oblique upper stretching, extension backward.Two kinds of methods all can obtain corresponding counterweight effect.
Claims (3)
1, the counterweight part of hydraulic truck crane is the fixed type counterweight.The utility model is characterized in that being respectively equipped with telescopic weight arm (2), (3) in the both sides of crane arm support (5), (6).
2, counterweight part according to claim 1 is characterized in that the minor details tail end of telescopic weight arm (2), (3) and balance weight body (1) join.
3, counterweight part according to claim 1 is characterized in that telescopic weight arm (2), (3) and balance weight body (1) form telescopic counter weight construction.
