Problems solved by technology

[0003] The existing standard joints have the following disadvantages when splicing: 1. Traditionally, angle steel is used for simple mechanical hinges, and bolts are used for locking and fixing. The splicing method is relatively simple. It is particularly easy to loosen during the process, causing potential safety hazards; 2. As the tower crane becomes taller, the standard section has higher requirements for its stability. The existing standard section cannot meet the use of high strength and high stability, and it is easy to cause standard section splicing The break at the place, causing unpredictable loss

Embodiment 1

[0029] Embodiment 1: The problems of inconvenient splicing of standard sections and poor stability are solved. This embodiment provides a fixed structure for standard sections of tower cranes. See Figure 1-7 Specifically, it includes a connecting pipe 12, an engaging mechanism, and a limit mechanism, the four connecting pipes 12 are vertically placed in parallel, and a cross bar 19 is provided between the ends of two adjacent connecting pipes 12, Both ends of each cross bar 19 are affixed to the ends of the corresponding connecting pipes 12, and two adjacent connecting pipes 12 are engaged and connected, and both ends of each connecting pipe 12 are provided with a limit mechanism; Between the two connecting pipes 12 there are several pairs of cross-placed reinforcing sloping plates 13, and the two ends of each reinforcing sloping plate 13 are welded and fixed to the side of the corresponding connecting pipe 12 respectively; The ends are respectively welded and fixed to the si...

Embodiment 2

[0031] Embodiment 2: One end of each connecting pipe 12 is recessed with a snap-in groove, and the other end protrudes outward with a snap-in block, and two adjacent connecting pipes 12 are correspondingly snapped into the snap-in groove through the snap-in block Cooperate connection to realize the snap connection of two adjacent connecting pipes; the rest of the structure is the same as that of Embodiment 1.

Embodiment 3

[0032] Embodiment 3: In Embodiment 1, there is also the problem that the internal splicing and engagement of the connecting pipe and the connecting pipe on another set of standard joints is not firm. Therefore, on the basis of Embodiment 1, this embodiment also includes:

[0033] In the present invention, the limit mechanism includes a limit rod 25 and a limit plate 210. A limit ring 24 is provided at the top end of the connecting pipe 12, and a limit rod 25 sliding through the limit ring 24 is inserted in the limit ring. 24 below is provided with limit stopper 26 at the bottom of limit bar 25, and connecting pipe 12 inner bottom end is provided with limit plate 210, is positioned at limit plate 210 below and is provided with a pair of inclined block 211 at connecting tube 12 inner bottom port, limit The top of the position rod 25 is inserted into the inner bottom of the corresponding connecting pipe 12 on another set of standard joints; between the inclined block 211 and the l...

Abstract

The invention discloses a fixing structure of tower crane standard sections. The fixing structure comprises connecting pipes, clamping mechanisms and limiting mechanisms, the four connecting pipes are vertically arranged in parallel, a transverse rod is arranged between the ends of every two adjacent connecting pipes, the two ends of each transverse rod are fixedly connected with the ends of the corresponding connecting pipes, every two adjacent connecting pipes are connected in a clamped mode, and the limiting mechanisms are arranged at the two ends in each connecting pipe. Through cooperative use of all the mechanisms, the problems that standard sections are inconvenient to splice and poor in stability are solved, and the overall structural design is compact; and through a multi-splicing fixing mode, the convenience of standard section splicing is improved, and the stability of the spliced standard sections is further improved.

Description

technical field [0001] The invention relates to the technical field of tower crane standard sections, in particular to a fixing structure for tower crane standard sections. Background technique [0002] A tower crane is a kind of lifting equipment used in building construction. Many people do not understand the rise of the tower crane itself. In fact, it is very simple. The tower crane has a jacking frame. When jacking up, the frame first rises upwards. There will be a space. At this time, the standard section of the tower body is installed in this space, and the frame is raised again, and the standard section is installed inside the vacated frame again. As it becomes higher, the standard section of tower cranes plays an important role in mechanical equipment such as tower cranes. [0003] The existing standard joints have the following disadvantages when splicing: 1. Traditionally, angle steel is used for simple mechanical hinges, and bolts are used for locking and fixing...
