Description

Anti-deformation inner tower body of tower crane

technical field

The utility model relates to an anti-deformation inner tower body of a tower crane, which is especially suitable for an inner jacking tower crane.

Background technique

For internal jacking tower cranes, a taller tower structure is usually required to meet the jacking stroke. The main body of the inner tower body is mainly composed of the main chord and the web, which are welded into a truss structure, which plays a role in supporting the upper half of the tower crane during work.

Generally, during the transportation and hoisting process of the taller tower structure, there are no good protective measures for the longer quadrilateral truss structure, and the diagonal deformation is prone to occur during the hoisting and transportation process, resulting in difficulties in docking installation during the installation process. .

At present, the method of remedying this deformation in the industry is generally as follows: most of them use auxiliary tools such as chain hoists to forcibly correct the deformation after on-site installation, and then install it. However, using auxiliary tools to forcibly correct the deformation after the deformation of the structural parts has certain safety hazards, and it also consumes a lot of manpower and time.

Contents of the invention

In order to solve the above problems, the utility model provides an anti-deformation inner tower body of a tower crane, so as to reduce the deformation problem during installation of the tower crane with this structure and improve the convenience of installation.

In order to achieve the above purpose, the utility model provides an anti-deformation inner tower body of a tower crane. Rods; the two ends of the diagonal braces are detachably connected to the main chord; in the hoisting and transportation state of the inner tower body, the diagonal braces are evenly distributed along the length direction of the main body of the tower body, and are installed on opposite sides of the rectangular cross-section. Corner line; after the installation of the inner tower body is completed and the tower crane is in use, the diagonal braces are suspended on the main chord.

Further, the two adjacent diagonal braces are arranged crosswise.

Further, both ends of the diagonal brace are detachably connected to the main chord through pins or bolts.

In view of the structural characteristics of the tower crane, the utility model adds six detachable diagonal struts at appropriate positions on the inner tower body. Through the installation of the diagonal struts, the easily deformed quadrilateral structure can be effectively transformed into two relatively stable ones. The triangular structure can reduce the deformation of the inner tower body during transportation and hoisting. Secondly, after the production of the inner tower body structure is completed, the diagonal braces are installed on the inner tower body through pins or bolts before hoisting and transportation, which is convenient and quick, and can well avoid the deformation of the inner tower body during hoisting and transportation. Ensure the key dimensions of the inner tower body and improve the installation efficiency of the tower crane; after the installation is completed, the diagonal braces can be removed and hung on the main chords on both sides of the inner tower body, which is convenient to prevent loss and does not affect the normal use of the tower crane.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, the utility model includes a tower main body 2, which is mainly composed of a main chord 21 and a web 22, and also includes six diagonal braces 1 designed in the entire length direction of the inner tower. Both ends of the diagonal brace 1 are detachably connected to the main chord 21, which is convenient for quick installation and disassembly.

As shown in Fig. 1, Fig. 2 and Fig. 3, when the inner tower body is hoisted and transported, the six diagonal braces 1 are evenly distributed along the length direction of the main body 2 of the tower body, and are installed on the diagonal of its rectangular cross section. , the original unstable quadrilateral structure is divided into two relatively stable triangular structures through the connection method of the diagonal struts 1, and the directions of the adjacent two diagonal struts 1 of the six diagonal struts 1 are arranged crosswise to prevent hoisting more effectively and deformation during transportation.

As shown in the dotted line in Figure 1, after the installation of the inner tower body is completed and the tower crane is in use, the diagonal brace 1 is suspended on the main chord 21 in the main body 2 of the tower body, which is convenient and quick. The problem of storing the strut 1 when it is not in use also avoids the problem that it is easy to lose when it is stored separately.

The implementation is that after the production of the main body 2 of the inner tower body is completed, the diagonal brace 1 is installed on the main body 2 of the inner tower body through pins or bolts before hoisting and transportation. Diagonal struts 1 need to be installed crosswise. After the installation of the tower crane is completed, the diagonal braces 1 can be removed and hung on the main chords on both sides of the inner tower body, which is the position shown by the dotted line in Figure 1, without affecting the normal use of the tower crane. Through the application of this technology, the safety and convenience in the installation process can be better improved, and the success rate of the installation is greatly improved.
