Abstract
The invention discloses a counter weight type hoisting limiting device of a crane. The counter weight type hoisting limiting device of the crane comprises a frame of the crane and a driving trolley slidably arranged on the frame, wherein a hoisting hook is arranged below the driving trolley; a limiting block is arranged at the upper end of the hoisting hook; a limiting controller is mounted on the frame; the lower end of the limiting controller is connected with a counter weight; the counter weight type hoisting limiting device of the crane is further provided with a limiting plate; one end of the limiting plate is connected with the counter weight while the other end of the limiting plate is hinged to a support frame; and the support frame is fixed on the lower part of the frame. According to the counter weight type hoisting limiting device of the crane, the limiting plate moves to a position above the hoisting hook through swinging of the counter weight, so that the limiting block is propped against the limiting plate when the hoisting hook ascends by a certain distance, the hoisting hook is prevented from being hoisted excessively, instability of the crane is reduced, and the service life of the crane is prolonged. The counter weight type hoisting limiting device of the crane is simple in structure, reasonable in design and convenient to use.
Description
Technical field
The present invention relates to crane technical field, particularly to a kind of crane heavy hammer type lifting stopping means.
Background technology
Crane refers to many actions hoisting machinery of vertical-lift within the specific limits and horizontal carrying heavy goods.Crane is as large-scale crane gear, and the cost buying crane neither a little number.In order to extend the life-span of lifting; make it more sturdy and durable; we be necessary for understand crane body in use it is possible that common situation; improper use in use would generally occur due to crane; cause crane sling too high after with vehicle frame collide; cause vehicle frame to damage, security incident can occur time serious.
Summary of the invention
In order to overcome drawbacks described above, the invention provides and a kind of be prevented from the crane heavy hammer type lifting stopping means that crane is sling too high.
The present invention is to solve that its technical problem be the technical scheme is that a kind of crane heavy hammer type lifting stopping means, including the vehicle frame of crane and be slidably arranged in the driving dolly on vehicle frame, what drive dolly is connected with crampon, the upper end of described crampon is provided with limited block, described vehicle frame is provided with a limit controller, the lower end of described limit controller connects a weight, it is additionally provided with a limiting plate, one end of described limiting plate connects weight, the other end is hinged on bracing frame, below the fixing vehicle frame of support frame as described above.
As a further improvement on the present invention, the lower section of described limiting plate is additionally provided with a buffer stopper, and the employing of described buffer stopper has elastic material and makes.
As a further improvement on the present invention, removably connect between described limiting plate and weight.
The invention has the beneficial effects as follows: the crane heavy hammer type lifting stopping means of the present invention utilizes the swing of weight that limiting plate moves the top to crampon, limited block is pushed against with limiting plate when crampon rising certain altitude, thus preventing crampon from excessively high being sling, reduce the unstability of crane, improve the service life of crane, present configuration is simple, reasonable in design, easy to use.
