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 the features of the present invention and the features in the present invention can be combined with each other in the case of an unable conflict.

[0034] In the present invention, it is to be understood that the orientation or positional relationship indicated by "deviation", "head", "height", "parallel", etc. is based on the orientation or positional relationship shown in the drawings, as well as actual use. The orientation or positional relationship is corresponding; the orientation of the orientation is usually referred to as the above-mentioned part of each component, as "internal, external" means the contour of each component itself. Not to indicate that the device or element referred to must have a specific orientation, constructed and operated in a specific orientation, and thus is not to be construed as limiting the invention.

[0035] The present invention will be described in detail below with reference to the drawings.

Abstract

The invention relates to the field of tower cranes, and discloses a tower crane and its climbing frame. One side of the climbing frame along the circumferential direction is an introduction surface. Installed to the introduction door at the opening, the introduction door includes a left door and a right door along the transverse direction of the introduction surface, and the sides of the left door and the right door are respectively facing away from each other. Pivotably connected to the climbing frame stringer on the corresponding side, so that the left door and the right door respectively have an open state rotated by at least 90° toward the outside of the lead-in face and an open position parallel to the lead-in face In the closed state, the introduction door further includes a connection mechanism for detachably connecting the left door and the right door in the closed state; the tower crane includes the climbing frame. The climbing frame can be easily disassembled at high altitude.

Description

Technical field [0001] The present invention relates to the field of tower cranes, and more particularly to a tower crane and a crawling rack. Background technique [0002] The installation and disassembly of the tower crane crawling rack is extremely common in the construction field. The installation and disassembly of traditional crawling frames is in place in the tower crane tower or the falling class, using a car crane to install the crawler in place or removed to the ground. If the tower crane is installed or removed when the crane is installed or removed, it will be very cumbersome. At this time, it can only be placed on the ground to climb the rack, and then the climbing racks will rise step by step until connected to the upper part, the whole process Firm. The structure of the existing climbing frame is mostly in the introduction of the mask with detachable front frame. When installing the climb, the front frame needs to be removed first, and then the climbing frame body ...
