[0002] A tower crane is a rotating crane with a jib installed on the upper part of the tower body. The characteristics of the tower crane determine that in addition to bearing the vertical force from the upper part, its lower structure also has to bear the overturning moment from the upper part. The underframes of most tower cranes work with a fixed connection to the ground, and the underframes of some tower cranes are equipped with a walking mechanism and set as a walking underframe.

[0003] According to a patent document with the publication number CN217578115U, which discloses a walking underframe and a tower crane, it includes a walking mechanism connected to the underframe main body. The underframe main body includes two parallel crossbeams and two parallel longitudinal beams, the longitudinal beams are perpendicular to and connected to the crossbeams, the walking mechanism is set with the walking direction consistent with the extension direction of the longitudinal beam or the crossbeam, the underframe main body also includes four auxiliary beams, the ends of the crossbeams extend out of the longitudinal beams, and one end of the auxiliary beam is connected to the crossbeam. When this technical solution is used, by setting parallel longitudinal beams and parallel crossbeams, and the longitudinal beams are perpendicularly connected to the crossbeams, and moreover, the extension direction of the longitudinal beam or the crossbeam is consistent with the walking direction of the walking underframe, the offloading during operation is avoided. For the above technical solution, although the consistency of the walking direction is achieved, it cannot provide sufficient support force for the tower crane when not moving, which is inconvenient during use. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a tower crane walking mobile control device to solve the problems raised in the above background technique. The structure of the utility model is novel. When in use, the movable seat moves inside the slotted opening to expose the position of the movable column, and the lifting mechanism contacts the base through the movable column. By moving the movable seat, the overall supporting area of the fixed frame is increased, and the re - movement of the movable seat is avoided through the movable column during use.

[0005] To achieve the above purpose, the utility model is realized through the following technical solutions: a tower crane walking mobile control device, including a base, a fixed seat is movably installed on the base, a fixed groove is opened at the bottom of the fixed seat, a guide rail is movably installed inside the fixed groove, the guide rail is welded on the base, a slotted opening is opened on the fixed seat, a movable seat is movably installed inside the slotted opening, a positioning column is welded on the side of the movable seat, and an opening is opened on the fixed seat, and the positioning column is movably installed inside the opening.

[0006] Furthermore, a fixed frame is fixedly installed on the movable seat, and a limiting block and a reinforcing rib are respectively fixedly installed on the side of the fixed frame.

[0007] Further, a fixing hole is formed in the limiting block, and a fixing bolt is rotatably installed inside the fixing hole, and one end of the fixing bolt is fixedly installed on the movable seat.

[0008] Further, a lifting mechanism is fixedly installed on the movable seat, a movable column is installed on the lifting mechanism, a limiting hole is formed in the inner wall of the slot, and one end of the movable column is movably installed inside the limiting hole.

[0010] Further, a power mechanism is fixedly installed on the side of the fixed seat, an output shaft is installed on the power mechanism, a roller is fixed at one end of the output shaft, and the roller is movably installed on the guide rail.

[0011] Advantages of the present utility model:

[0012] 1. For this tower crane walking and moving control device, when in use, the position of the movable column is exposed as the movable seat moves inside the slot. The lifting mechanism contacts the base through the movable column. By moving the movable seat, the overall supporting area of the fixing frame is increased, and the movement of the movable seat is avoided during use through the movable column.

[0013] 2. For this tower crane walking and moving control device, when the movable seat moves along with the fixed seat, one end of the movable column enters into the limiting hole to limit and fix the movable seat. The movable seat provides double support and positioning through the sliding block and the positioning column, avoiding damage caused by the inclination of the movable seat on the fixed seat.
