Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction equipment technology, and in particular to a tower crane attachment lug suitable for the construction of small cross-section steel columns. Background Technology
[0002] Tower cranes are large-scale mechanical equipment widely used in construction. The attached lugs of the tower crane are an important component of the tower crane, and their existence is closely related to the working principle and safety requirements of the tower crane.
[0003] A search revealed Chinese patent CN214243538U, which discloses a detachable tower crane attachment connecting lug, relating to the tower crane field. This detachable tower crane attachment connecting lug includes a connecting lug body and a tower crane fixing frame. A positioning and fixing block is installed at the lower end of the connecting lug body. A disassembly and adjustment frame is installed at the left end of the tower crane fixing frame. A positioning and fixing groove is formed at the upper end of the tower crane fixing frame. A first limiting slide groove is formed at the right end of the positioning and fixing groove. A limiting pin is installed inside the first limiting slide groove. A first manual pull block is installed at the right end of the limiting pin. A limiting groove is formed at the lower end of the limiting pin. A second limiting slide groove is formed inside the disassembly and adjustment frame. The detachable lug solves the problem of reusing the attachment lug of the tower crane, greatly reducing costs and processing time.
[0004] Based on the above search results combined with existing technologies;
[0005] Although the aforementioned patents involve detachable lugs, during construction, it is often encountered that the steel column cross-section is small, and the size of the attached connecting lug is larger than the side length of the steel structure cross-section, resulting in the lug being unable to connect to the steel column. This makes it impossible to guarantee the stability and safety of the tower crane during operation, thus presenting certain limitations. Utility Model Content
[0006] To address the aforementioned technical problems, this utility model proposes a tower crane attachment lug suitable for the construction of small-section steel columns, which adapts to the construction needs of small-section steel columns and improves construction speed and efficiency.
[0007] The technical solution to achieve the purpose of this utility model is: a tower crane attachment lug plate suitable for the construction of small cross-section steel columns, including a steel column, a lug plate is fixedly installed on one side of the steel column, and a pair of through holes are opened on one side of the lug plate, and a pin is inserted into the interior of each through hole.
[0008] Preferably, the ear plate is fixedly mounted with a connecting steel plate by a pin, and the connecting steel plate has a through hole that matches the pin.
[0009] Preferably, the top of the connecting steel plate is fixedly provided with a fixed plate, and the fixed plate is fixedly connected with a connecting support through a threaded rod.
[0010] Compared with the prior art, the utility model has the following remarkable advantages:
[0011] Firstly, the ear plate is directly welded with the small-section steel column, so that the labor intensity of workers is reduced, and the practicability and flexibility of the structure are enhanced.
[0012] Secondly, the tower crane attachment ear plate improves the stability of the tower crane, enhances the bearing capacity, helps the tower crane to adapt to different construction environments, is convenient to install and disassemble, can be repeatedly used, saves materials, reduces construction cost, and has higher economic benefits.
[0013] The problem that the ear plate cannot be connected with the steel column, so that the stability and safety of the tower crane during operation cannot be ensured is solved. BRIEF DESCRIPTION OF DRAWINGS
