Description

Tower crane auxiliary trolley

Technical Field

The utility model relates to the field of constructional engineering, in particular to an auxiliary trolley for a tower crane.

Background

The tower crane is the most common hoisting equipment in construction sites, also known as tower crane, and is used for hoisting construction raw materials such as reinforcing steel bars, wood ridges, concrete, steel pipes and the like for construction. A hoisting steel wire rope of the tower crane is used for lifting load, the hoisting steel wire rope is only supported by two ends and three positions of the amplitude-variable trolley at the front arm part, when the amplitude-variable trolley moves to the farthest end, the effective supporting part of the hoisting steel wire rope only has the nearest end structure and the amplitude-variable trolley, and the middle section of the hoisting steel wire rope can seriously droop due to gravity. At this moment, if promote lighter heavy burden to the top, when the tower crane stopped, play to rise wire rope and receive the influence of inertia and self weight can seriously hang down, and then drive the heavy burden and continue the motion, will lead to the heavy burden to jolt, can lead to the lifting hook to strike the dolly that becomes width of cloth even. Has great potential safety hazard.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide an auxiliary trolley for a tower crane, which can support a lifting steel wire rope when the lifting steel wire rope excessively sags. When the lifting machine stops, the lifting steel wire rope is prevented from driving the load to continue moving, and the lifting hook is prevented from impacting the amplitude-variable trolley.

In order to achieve the purpose, the utility model is realized by the following technical scheme:

a tower crane auxiliary trolley comprises a trolley body; the crane comprises a crane body and is characterized in that sliding idler wheels are arranged on two sides of the crane body and can slide on a sliding rail together with an amplitude-variable trolley, a supporting pulley fixed through a supporting frame is arranged on the crane body, a traction mechanism is arranged on the crane body and is connected with the crane body and the amplitude-variable trolley, a limiting plate is arranged on the crane body, and a limiting support matched with the limiting plate is arranged in the middle of a forearm of a tower crane.

And the support frame is provided with an anti-jumping rope bolt which is matched with the support pulley.

The traction mechanism is an automatic wire-rewinding device which connects the auxiliary trolley with the amplitude-variable trolley through a traction rope.

The hauling cable is a thin steel wire rope.

And buffer rubber pads are arranged at the two ends of the vehicle body.

Compared with the prior art, the utility model has the beneficial effects that:

this auxiliary trolley can prevent to rise wire rope and excessively droop to rise wire rope support, makes the tower crane more accurate to the control of lifting hook. The lifting hook can be prevented from driving load to continue moving when the lifting machine stops, the lifting hook can be stopped effectively, the lifting hook is prevented from continuing moving and impacting the amplitude-variable trolley, the amplitude-variable trolley can be protected, and potential safety hazards can be reduced.

Detailed Description

The utility model will be further illustrated with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and these equivalents also fall within the scope of the present application.

The utility model relates to a tower crane auxiliary trolley, the main structure of which comprises a trolley body 1; the two sides of the trolley body 1 are both provided with sliding idler wheels 2, the sliding idler wheels 2 can slide on the sliding rails together with the amplitude-variable trolley, and the sliding idler wheels 2 are arranged at the two ends of the trolley body 1 and slide on the sliding rails and can support the trolley body 1 to move along the sliding rails. Be equipped with on automobile body 1 through the fixed supporting pulley 4 of support frame 3, supporting pulley 4 passes through support frame 3 and establishes on automobile body 1, can support the wire rope that rises, prevents to rise that wire rope excessively droops. The crane comprises a crane body 1 and is characterized in that a traction mechanism is arranged on the crane body 1, the traction mechanism is connected with the crane body 1 and an amplitude-variable trolley, a limiting plate 5 is arranged on the crane body 1, a limiting support 6 matched with the limiting plate 5 is arranged in the middle of a front arm of a tower crane, the crane body 1 can be driven by the amplitude-variable trolley through the traction mechanism, the limiting support 6 stops moving at a specified position under the action of the limiting plate 5 and the limiting support 6, the limiting support 6 is arranged in the middle of the front arm of the tower crane, the auxiliary trolley can slide in a limiting manner in the front half section of the front arm of the tower crane, and the auxiliary trolley can support a lifting steel wire rope at the best position.
