The entire wall-attached strut is in the shape of a cross, and the cross-shaped wall-attached strut is composed of two cross-shaped half-beam components , the two half-beam parts are fixedly connected by pin shafts, one end of the half-beam part is provided with a threaded sleeve, and an adjusting bolt is provided between the threaded sleeve and the half-beam part, and the other end of the threaded sleeve forms a right-angled top tight end, and the other end of the half-beam component also forms a right-angled top tight end. It adopts a split assembly structure, using two single half-beam parts to assemble a cross-shaped wall-attached inner strut, and uses a threaded casing mechanism to realize the connection with the main branch of the tower crane standard section. The structural design of the whole set of inner struts is reasonable, with good practicability, strong versatility, low daily use and maintenance costs, stable fastening effect of parts, high safety factor of construction, reasonable assembly structure design of products, and relatively easy disassembly and assembly. Simple and easy to promote and apply.

Description

A New Type of Tower Crane Attached to Wall Inner Struts

technical field

The utility model relates to the technical field of tower crane accessories, in particular to a novel tower crane attached to a wall inner strut, in particular to the mechanical connection structure of the inner strut.

Background technique

When installing the wall attached to the tower crane, in order to ensure the stability of the local stress on the standard section of the tower crane, it is necessary to install the inner struts of the attached wall frame. The existing inner struts are standard custom-made sizes, and the flexibility of use is poor. Both are very inconvenient.

Utility model content

The purpose of this utility model is to provide a new type of tower crane attached to the wall inner strut, which adopts the assembly structure of a single half-beam part, cooperates with an adjustable length threaded sleeve, and finally realizes that the inner strut and the tower crane standard section are mainly connected. connection of branches.

In order to achieve the above object, the technical solution of the utility model is: a new type of wall-attached inner brace for a tower crane, which is characterized in that: the overall attached wall inner brace is in the shape of a cross, and the cross-shaped wall-attached inner brace The rod is composed of two half-beam parts distributed in a cross shape, and the two half-beam parts are fixedly connected by pin shafts. One end of the half-beam part is provided with a threaded sleeve, and there is a threaded sleeve between the half-beam parts. Adjusting the bolt, the other end of the threaded casing forms a right-angled tight end, and the other end of the half-beam component also forms a right-angled tight end.

This case discloses a new type of wall-attached strut for a tower crane, which adopts a split assembly structure, uses two single half-beam components to assemble a cross-shaped wall-attached strut, and utilizes a threaded sleeve mechanism to realize the connection with the wall. The connection of the main branch of the tower crane standard section. The structural design of the whole set of inner struts is reasonable, with good practicability, strong versatility, low daily use and maintenance costs, stable fastening effect of parts, high safety factor of construction, reasonable assembly structure design of products, and relatively easy disassembly and assembly. Simple and easy to promote and apply.

Detailed ways

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

The utility model discloses a novel wall-attached strut for a tower crane, which includes a wall-attached strut 1 as a whole in the shape of a cross, and the cross-shaped wall-attached strut consists of two cross-shaped half The beam part 2 is composed of two half-beam parts 2 fixedly connected by a pin shaft 3, one end of the half-beam part 2 is provided with a threaded sleeve 4, and an adjusting bolt 9 is provided between the threaded sleeve 4 and the half-beam part 2, The other end of the threaded sleeve 4 forms a right-angled tightening end 5 , and the other end of the half-beam component 2 also forms a right-angled tightening end 5 .

In specific implementation, the half-beam part 2 is composed of a left half-beam 6 , a pin-fixed rib 7 , and a right half-beam 8 , which are sequentially fixedly connected, and the pin-fixed rib 7 is provided with a pin hole.

In the specific implementation, the two half-beam parts 2 distributed in a cross form a fixed point at the fixed rib plate 7 where the two pin shafts overlap through the pin shaft part, and then the tightness adjustment of the top tight end is realized by adjusting the bolt, and the threaded sleeve 4 Push out to the outside, and finally realize the connection with the main branch of the standard section of the tower crane.

The above content is a further detailed description of the utility model in combination with specific preferred embodiments, and it cannot be assumed that the specific implementation of the utility model is limited to the above descriptions. For a person of ordinary skill in the technical field to which the utility model belongs, without departing from the concept of the utility model, some simple deduction or substitutions can also be made, which should be regarded as belonging to the protection scope of the utility model.
