Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dam surface maintenance construction, in particular to a crane system used for dam surface maintenance. Background Art
[0002] At present, when carrying out maintenance construction on the dam surface, it is necessary to use a manned basket to lower the basket along the dam surface on the dam top to carry out operations. Conventional baskets are generally towed by winches. The problem with this method is that the horizontal span of the maintenance position is large, and the winch needs to be moved along the retaining wall on the dam top through mobile equipment to drive the basket to move along the dam surface for maintenance. During the process, the winch is subjected to a large pulling force from the basket, causing the basket to sway greatly, posing a safety hazard.
[0003] The prior art also uses a method of combining a truck crane with a hanging basket. However, since a conventional truck crane needs to repeatedly operate the hydraulic support mechanism at the bottom of the vehicle during the movement of the vehicle, the process of adjusting the position of the hanging basket is time-consuming during the maintenance of a wide range of dam surfaces. Summary of the invention
[0004] The technical problem to be solved by the utility model is to provide a crane system for dam surface maintenance, which can effectively solve the cumbersome problem of adjusting the position of the hanging basket during maintenance operations over a wide range of the dam surface, and perform transverse adjustment of the position of the hanging basket without moving the crane.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a crane system for dam surface maintenance, including a crane body, a base is provided on the crane body, a control room is provided on the base, a main boom is provided on the control room, one end of the main boom is hinged to the control room, and a telescopic arm is provided on the other end, the telescopic arm is arranged in a cavity at one end of the main boom, a suspension seat rotating seat is provided on the other end of the telescopic arm, and a hanging basket is provided on the suspension seat rotating seat.
[0006] In a preferred solution, the base is provided with a control chamber rotating seat capable of axial rotation, and the control chamber is fixedly arranged on the control chamber rotating seat.
[0007] In a preferred solution, a first adjusting hydraulic cylinder body is provided on the control room, the first adjusting hydraulic cylinder body is hinged to the control room, and the push rod end of the first adjusting hydraulic cylinder body is hinged to the middle position of the main boom.
[0008] In a preferred solution, a second adjusting hydraulic cylinder is fixed on the main boom, and a push rod end of the second adjusting hydraulic cylinder extends toward the telescopic arm and is fixedly connected to the telescopic arm.
[0009] In a preferred solution, the suspension seat rotating seat is hinged to the end of the telescopic arm, and a third adjusting hydraulic cylinder is provided on the telescopic arm. The push rod end of the third adjusting hydraulic cylinder is fixedly connected to the suspension seat rotating seat.
[0010] In a preferred solution, the hanging seat rotating seat can drive the hanging basket hanging seat and the hanging basket to rotate axially around the hanging seat rotating seat itself.
[0011] The crane system for dam surface maintenance provided by the utility model has the following beneficial effects by adopting the above-mentioned structure: the free rotation of the boom after the crane is fixed is realized by the control room rotating seat, and the reverse synchronous rotation of the hanging seat rotating seat during the rotation process can ensure the lateral movement of the hanging basket along the dam surface direction, and can ensure that the hanging basket is always parallel to the dam surface during the entire movement process, so as to facilitate the normal progress of the dam surface maintenance work.
