Problems solved by technology
The wire rope guide of this structure is prone to serious wear and tear due to the heavy load generated by the wire rope hoisting heavy objects, especially when the side force of the wire rope is constantly changing at different positions on the reel, it will repeatedly act on the wire rope guide. , which greatly reduces the service life of the wire rope guide device, thereby increasing the maintenance workload of the device

Embodiment
[0021] Such as figure 1 As shown in , the wire rope 2' of the telescopic boom crane of this embodiment is not provided and is directly connected to the arm pulley at the other end of the telescopic boom 1 from the winch 4, and is wound and connected to the hook through the boom pulley, so that the telescopic crane When the arm reaches a longer length, the wire rope between the arm head pulley and the hoist is almost straightened and is perpendicular to the drum. At this time, the wire rope lacks lateral force during the winding and arranging process, which may easily lead to hoisting. When retrieving the wire rope, rope climbing will occur at the edge of the rope.
[0022] See you again figure 1 , the present embodiment installs the pressure rope guide wheel mechanism 3 on the telescopic boom 1 between the hoist 4 and the arm head pulley of the telescopic boom crane, and the steel wire rope 2 on the hoist 4 passes through the rope pressure guide wheel mechanism 3 and then con...

The invention discloses a telescopic arm crane winch anti-climbing device. The device comprises a rope pressing guide wheel mechanism, wherein the rope pressing guide wheel mechanism is arranged on atelescopic suspension arm between a winch and an arm head pulley of the telescopic arm crane, and a steel wire rope on the winch penetrates through the rope pressing guide wheel mechanism and is connected to the arm head pulley in a winding mode; the rope pressing guide wheel mechanism comprises a support, a rope guide pulley and a rope supporting roller wheel, wherein the rope guide pulley and the rope supporting roller wheel are arranged on the support; the rope guide pulley is installed on the support through a sliding wheel shaft in a rotating mode, and the rope guide pulley is further arranged on the sliding wheel shaft in a sliding mode and is provided with an axial sliding space; and the rope supporting roller wheel is parallel to the sliding wheel shaft, and the steel wire rope penetrates through the gap between the surface of the rope supporting roller wheel and a wheel groove of the rope guide pulley. According to the device, the rope climbing phenomenon caused by winding ofthe steel wire ropes on the winch can be effectively avoided; and redundant lateral force generated by the steel wire rope can be eliminated by adopting a sliding mounting structure, the abrasion of the device is reduced, the service life is greatly prolonged, the working efficiency of the telescopic arm crane is improved, and the maintenance workload is reduced.
Description
technical field [0001] The invention belongs to the technology of crane equipment, and in particular relates to a hoisting anti-climbing rope device for a telescopic arm crane. Background technique [0002] The telescopic boom crawler crane has the characteristics of both a truck crane and a crawler crane. It has the advantages of small working space, convenience and quickness, no disassembly and assembly, all-weather road operation, and the ability to drive with a load. During the operation, the length of the boom can be adjusted according to the actual situation. However, when the boom reaches a longer length, the wire rope between the pulley at the boom head and the winch is almost in a straight line perpendicular to the drum. Due to the lack of lateral It is easy to cause rope climbing on the edge of the rope when the winch recovers the wire rope, which seriously affects the use efficiency of the winch and the lifting safety. [0003] The Chinese patent document with th...
