Description

Technical Field

[0001] This utility model relates to the field of tower structure components, specifically an anti-corrosion tower structure component. Background Technology

[0002] Tower cranes, also known as tower hoists, originated in Western Europe. They are rotating cranes with a jib mounted on the upper part of a tall tower. Generally, tower crane components can be divided into the following parts according to their functions: foundation, tower body, jacking, slewing, hoisting, counterweight jib, lifting jib, trolley, tower top, operator's cab, and luffing mechanism. The counterweight is a key component ensuring the stability of the tower crane, preventing tipping through balancing torque. Its design and configuration must adhere to the lever principle and mechanical balance requirements. The weight, position, and fixing method of the counterweight directly affect the safe operation of the tower crane and require precise calculations considering factors such as the lifting load and structural parameters.

[0003] A tower crane counterweight balance block with application number 201922273475.9 in the prior art includes an upper plate, a lower plate, a side plate, and a baffle. By setting the side plate and baffle, the height of the side plate and baffle can be changed according to actual needs. The internal concrete block is poured on site after the side plate and baffle are adjusted. The weight and size of the concrete block can be controlled to meet the needs of tower cranes of different models or with different counterweights. At the same time, the side plate is detachable. However, the connection and fixing stability of the tower crane counterweight components is poor, and it is inconvenient to disassemble and use, making it difficult to replace severely damaged parts. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a corrosion-resistant tower crane component, including a tower crane counterweight, wherein the tower crane counterweight includes a first end plate and a second end plate, a side end plate is inserted into the insertion holes inside the first end plate and the second end plate, a hook is provided on one side of the side end plate, a screw is rotatably provided in a first sliding groove on one side of the first end plate and the second end plate, and a locking plate is threaded on both ends of the screw, the side end plate is provided with locking holes that cooperate with the locking plates, an anti-corrosion cover plate is snapped onto the outside of the first sliding groove, and a pry opening is provided at one end of the anti-corrosion cover plate.

[0006] Furthermore, one end of the first end plate and the second end plate is provided with a snap-fit ​​seat, and one side of the anti-corrosion cover is provided with a snap-fit ​​groove that engages with the snap-fit ​​seat.

[0007] Furthermore, the outer side of the snap-fit ​​seat is provided with a limiting rib, and the inner wall of the snap-fit ​​groove is provided with a limiting snap groove that engages with the limiting rib. One end of the limiting rib is provided with a sealing gasket.

[0008] Furthermore, the first end plate, the second end plate, the side end plate, and the anti-corrosion cover plate are all made of stainless steel, and the stainless steel plates are coated with an epoxy anti-rust paint layer.

[0009] Furthermore, multiple inner core columns are welded to one side of the first end plate, and concrete counterweights are fitted on the outer sides of the multiple inner core columns.

[0010] Furthermore, the screw has an adjustment knob in the middle, and two opposite external threads and a limiting end plate on the outer sides of both ends of the screw.

[0011] Furthermore, the inner wall of the first groove is provided with guide ribs, and the locking plate is provided with second grooves on both sides that are slidably arranged with the guide ribs.

[0012] Compared with the prior art, the beneficial effects of this utility model are:
