The utility model aims at providing a tower crane dolly traction wheel protection device can improve the stability that wire rope and traction wheel are connected, reduces the probability that the incident takes place.
Description
Technical Field
The utility model relates to a tower crane field specifically is a tower crane dolly traction wheel protection device.
Background
The tower crane is a common device in building construction, a variable amplitude trolley (trolley for short) is arranged on one side of a tower crane boom, a plurality of travelling wheels are mounted on the trolley and move under the driving of a traction mechanism, the traction mechanism comprises a motor, a winding drum, a steel wire rope, a traction wheel and the like, the steel wire rope winds the winding drum and the traction wheel, the motor is used for driving a planetary reducer to drive the winding drum at the rear end of the boom to rotate in the specific traction process, the steel wire rope does retraction and release movement along with the rotation of the winding drum so as to pull the trolley to travel along a lower chord of the boom, and the steel wire rope can slide on the traction wheel at the. The steel wire rope may slip out of the traction wheel due to collision, looseness and the like, so that a serious safety accident is caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at above problem, provide a tower crane dolly traction wheel protection device, can improve the stability that wire rope and traction wheel are connected, reduce the probability that the incident takes place.
In order to realize the above purpose, the utility model adopts the technical scheme that: the steel wire rope is limited between the wire pressing roller and the traction wheel, in order to achieve the effect, two axial sides of the traction wheel are movably arranged on a vertical plate, and the vertical plate is arranged at the front end of a tower crane boom in a welding mode and the like; the protection board is arranged between the vertical boards on the two sides and outside the traction wheel, the protection board is provided with stand columns on one side of the traction wheel at intervals, and the stand columns on the two sides are connected with the wire pressing roller through rotating shafts.
Further, for the convenience passes wire rope from between traction wheel and the line ball roller during tower crane installation, for the convenience maintains the line ball roller simultaneously, the protection shield passes through bolt detachable and sets up on the riser.
Furthermore, the protection shield passes through the spring and is connected with the baffle in traction wheel back of the body one side mutually, and the elasticity through the spring is to the impact force of traction wheel when slowing down the object and striking the protection shield, improves crashworthiness.
Furthermore, the outer diameters of the left end and the right end of the wire pressing roller are larger than the outer diameter of the middle of the wire pressing roller, so that the left-right movement distance of the wire pressing roller is limited in the movement process of the wire rope, and the wire rope is prevented from being separated from the traction wheel as far as possible.
The utility model has the advantages that: the steel wire rope passes through the space between the wire pressing roller and the traction wheel so as to avoid the separation of the steel wire rope from the traction wheel under the action of external force or other factors, thereby improving the connection stability of the steel wire rope and the traction wheel; meanwhile, the protective plate is arranged on the outer side of the traction wheel, so that an object can be prevented from directly impacting the traction wheel, and safety accidents caused by damage of the traction wheel or separation of the traction wheel and a steel wire rope are reduced.
1. The outer diameters of the two ends of the wire pressing roller are larger than that of the middle part of the wire pressing roller, so that the wire rope is prevented from moving out of the space between the wire pressing roller and the traction wheel in the movement process.
2. The protection shield passes through the spring and is connected with the baffle in traction wheel back of the body one side mutually, can improve traction wheel's crashworthiness.
