Description

Technical Field

[0001] The utility model belongs to the technical field of tower cranes, in particular to an assembled flat-top tower crane. Background Art

[0002] Tower crane, also known as tower crane, originated in Western Europe. It is a rotating crane with a boom mounted on the top of a tall tower. It has a large working space and is mainly used for vertical and horizontal transportation of materials and installation of building components in house construction. It consists of three parts: metal structure, working mechanism and electrical system. The metal structure includes the tower body, boom and base. The working mechanism has four parts: lifting, luffing, rotation and walking. The electrical system includes motors, controllers, distribution cabinets, connecting lines, signals and lighting devices, etc. Flat-top tower crane is a heavy lifting equipment widely used in the fields of construction and engineering. Its notable feature is that there is no traditional tower head structure or tie rod on the top of the tower. This design makes the overall outline of the tower crane simpler, and it is more convenient to install and disassemble. It also improves the safety and efficiency of multi-tower cross operations.

[0003] For example, a tower crane foundation with publication number CN214940351 U includes bored piles, reinforced concrete cushion layers arranged at the top of the bored piles, lattice columns connected to the bored piles, concrete caps arranged at the top of the lattice columns, and a cross beam foundation arranged on the surface of the concrete cap. This application has the advantage of being able to withstand a larger load;

[0004] When installing this tower crane, it is necessary to cast the foundation at the installation site. The installation efficiency of this tower crane structure is low. In order to solve the above problem, an assembled flat-top tower crane is proposed. Utility Model Content

[0007] The tower crane standard section is fixedly installed on the top of the connecting base. The four corners of the bottom of the tower crane standard section are provided with plug rods, and the four corners of the top of the tower crane standard section are provided with slots.

[0008] Through the above technical solution, when the tower crane needs to be assembled, first move the mobile foundation to the position where the tower crane needs to be installed, then fix and install the connecting base on the corresponding position of the upper surface of the steel frame according to the size of the tower crane, and then insert the insertion rod at the bottom of the tower crane standard section into the inside of the connecting base and fix it with bolts. When stacking the tower crane standard sections, rapid assembly can be achieved by inserting the insertion rod of the upper standard section into the slot of the lower standard section. At the same time, with the structure of the mobile foundation, it is not necessary to pour before installing the tower crane, which greatly improves the installation efficiency of the tower crane.

[0009] In a preferred embodiment, pressing blocks are arranged on the four sides of the upper surface of the mobile foundation.

[0010] Through the above technical solution, the mobile foundation is pressed and fixed by placing a plurality of pressing blocks on the upper surface of the mobile foundation, improving the stability of the mobile foundation.

[0011] In a preferred embodiment, grooves adapted to the pressing blocks are formed on the upper surface of the mobile foundation.

[0012] Through the above technical solution, the pressing blocks can be quickly placed on the upper surface of the mobile foundation through the grooves.

[0013] In a preferred embodiment, reinforcing bars are fixedly installed on the inner walls of the four sides of the tower crane standard section.

[0014] Through the above technical solution, the strength of the tower crane standard section is improved by fixedly installing reinforcing bars on the inner wall of the tower crane standard section.

[0015] In a preferred embodiment, a plurality of locking convex blocks are fixedly installed on the outer walls of the front and rear sides of the tower crane standard section by bolts.

[0016] Through the above technical solution, the climbing mechanism of the tower crane performs a locking operation through the locking convex platform.

[0017] In a preferred embodiment, a plurality of through holes are formed on the outer walls of the insertion rod and the slot.

[0018] Through the above technical solution, after the insertion rod is inserted into the inside of the slot, bolts can be fixed in the through holes to achieve fixation.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effect of the present utility model is: The present utility model provides an assembled flat-top tower crane.

[0020] When the tower crane needs to be assembled, first move the mobile foundation to the position where the tower crane needs to be installed, then fix and install the connecting base on the corresponding position of the upper surface of the steel frame according to the size of the tower crane, and then insert the insertion rod at the bottom of the tower crane standard section into the inside of the connecting base and fix it with bolts. When stacking the tower crane standard sections, quick assembly can be achieved by inserting the insertion rod of the upper standard section into the slot of the lower standard section.
