Description

TECHNICAL FIELD

[0001] The utility model relates to building equipment technical field, concretely relates to a height adjustable combined roof hanging cross beam. BACKGROUND

[0002] With the rapid development of modernization, more and more buildings are built, and more and more mechanical structures are applied in the buildings. The most widely used in the buildings is tower crane, which is also called tower crane. It is mainly used in housing construction and is suitable for horizontal and vertical conveying of materials in building construction. It can also be used for the installation of building components. It is a common transportation equipment in building construction. The general height of tower crane is dozens of meters to hundreds of meters. Therefore, the demand for roof hanging, an important tool for tower crane installation, is increasing. The cross beam at the lower part of the roof hanging needs to be installed on the top surface of the building. The top surface of the building has many devices, and the structure design is complex and variable. The installation position is sometimes uneven, which brings a lot of inconvenience to installation.

[0003] Now the height of the roof hanging support is fixed, which requires high flatness of the installation foundation. In most cases, the foundation surface needs to be treated, increasing the workload of on-site installation.

[0004] For the roof with an inclination angle, the building needs to be designed to change, and a special foundation needs to be made. After the roof hanging work is completed, the foundation concrete may need to be removed, increasing the workload of building construction. CONTENT OF THE UTILITY MODEL

[0005] In view of the deficiencies of the prior art, the utility model provides a height adjustable combined roof hanging cross beam, which comprises a center beam, an intermediate beam, a lengthening beam and a threaded sleeve end beam piece connected in sequence. The intermediate beam is connected with a foot seat through a bolt group. One side of the threaded sleeve end beam piece is provided with a height adjusting mechanism. The lower end of the height adjusting mechanism is provided with a base.

[0006] As a further improvement of the utility model, the height adjusting mechanism comprises a height adjusting screw rod. A stop nut is installed on the height adjusting screw rod. An adjusting hand wheel is installed on the upper end of the height adjusting screw rod. The lower end of the height adjusting screw rod is connected with the base.

[0007] As a further improvement of the utility model, a support pressing block is installed between the height adjusting screw rod and the base.

[0008] As a further improvement of the utility model, the support pressing block and the base are fixed together through bolts and are clamped on the spherical body at the lower part of the height adjusting screw rod.

[0009] As a further improvement of the utility model, the center beam, the intermediate beam, the lengthening beam and the threaded sleeve end beam piece are connected through a bolt group.

[0010] The utility model discloses beneficial effect:

[0011] Cross beam height can be adjusted, and the cross beam height is adjusted through heightening screw rod, meets the use of standing and hoisting environment of uneven ground or obvious height difference. Save design change, reduce basic construction work;

[0012] Utilize combination formula structure, satisfy the use of small space to reduce single piece weight, be convenient for transportation and hoist, reduce use cost, improve work efficiency. BRIEF DESCRIPTION OF DRAWINGS

[0016] In order to facilitate understanding of the present application, the present application will be described more comprehensively below with reference to the relevant drawings. The embodiments described are shown in the drawings. Conversely, the purpose of providing these embodiments is to make the disclosure of the present application more comprehensive and comprehensive.

[0017] As Figure 1 Shown, a height -adjustable combined roof hoist cross beam, including sequentially connected center beam 1, intermediate beam 3, lengthening beam 4, threaded sleeve end beam piece 5, the intermediate beam 3 is connected with foot base 2 through bolt group 11, one side of threaded sleeve end beam piece 5 is equipped with height -adjusting mechanism, the lower end of height -adjusting mechanism is equipped with base 10. The height -adjusting mechanism includes heightening screw rod 7, the heightening screw rod 7 is installed with stop nut 8, the upper end of heightening screw rod 7 is installed with adjusting hand wheel 6, the lower end of heightening screw rod 7 is connected with base 10. Between the heightening screw rod 7 and base 10, install support pressing block 9. The support pressing block 9 and base 10 are fixed together through bolt group 11, and are embraced on the ball body under the heightening screw rod 7. The center beam 1, intermediate beam 3, lengthening beam 4, threaded sleeve end beam piece 5 are connected through bolt group 11.

[0018] The length of the device can be adjusted, and the height of the support can be adjusted. When used in a narrow space, the lengthening beam can be removed, and a small size cross beam can be used. For uneven foundation, the heightening screw rod 7 is adjusted to ensure the horizontal work of the roof hoist. Reduce the workload and improve the work efficiency.

[0019] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several modifications and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
