Problems solved by technology

It will be very cumbersome to install or remove the climbing frame when the tower crane is used to a certain height. At this time, the climbing frame can only be assembled on the ground, and then the climbing frame is lifted step by step until it is connected with the upper part. The whole process is time-consuming strenuous
The structure of the existing climbing frame mostly has a detachable front frame on the introduction surface. When installing the climbing frame, the front frame needs to be removed on the ground first, and then the main part of the climbing frame is set at a certain height of the tower body before the front frame is installed. Lifting to this height and installing back to the main body of the climbing frame, the operation is cumbersome and the aerial work is difficult and dangerous

Embodiment Construction

[0033] It should be noted that, in the case of no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0034] In the present invention, it should be understood that the orientations or positional relationships indicated by the terms "deviating from", "facing", "height", and "parallel" are based on the orientations or positional relationships shown in the drawings, and are also different from those actually used. Corresponding orientation or positional relationship; the orientation words used such as "upper and lower" usually refer to the upper and lower as shown in the drawings; "inner and outer" refer to the inner and outer relative to the outline of each part itself; and No indication is made that a referenced device or element must have a particular orientation, be constructed, and operate in a particular orientation and thus should not be construed as limiting the invention.

Abstract

The invention relates to the field of tower cranes, and discloses a tower crane and a climbing frame thereof. An introduction face is arranged on the side, in the circumferential direction, of the climbing frame, and is provided with an opening which is through up and down, the climbing frame is provided with an introduction face door which is detachably mounted on the opening, the introduction face door comprises a left door and a right door in the transverse direction of the introduction face, the sides, away from each other, of the left door and the right door are connected to climbing frame longitudinal beams on the corresponding sides in a pivot manner, the left door and the right door each have an opening state capable of rotating by at least 90 degrees facing the outer side of the introduction face and a closing state parallel to the introduction face, the introduction face door further comprises a connecting mechanism which is used for detachable connection of the left door andthe right door which are in the closed state, the tower crane comprises the climbing frame, and the climbing frame can be conveniently dismounted and mounted in the high air.

Description

technical field [0001] The invention relates to the field of tower cranes, in particular to a tower crane and a climbing frame thereof. Background technique [0002] The installation and disassembly of the tower crane climbing frame is extremely common in the construction field. The installation and disassembly of the traditional climbing frame is to use the truck crane to install the climbing frame in place or remove it to the ground for disintegration during the erection or lowering process of the tower crane. It will be very cumbersome to install or remove the climbing frame when the tower crane is used to a certain height. At this time, the climbing frame can only be assembled on the ground, and then the climbing frame is lifted step by step until it is connected with the upper part. The whole process is time-consuming strenuous. The structure of the existing climbing frame mostly has a detachable front frame on the introduction surface. When installing the climbing fr...
