Description

Technical Field

[0001] This utility model relates to the field of tower climbing technology, and in particular to a box-type guide rail for a hydraulic climbing device for tower construction machines. Background Technology

[0002] The tower crane's working platform moves up and down along guide rails during lifting. Traditional I-beam guide rails cannot meet the strength requirements of the tower crane's working platform, so box-type rails are often used in this field, such as the climbing rail described in the patent with authorization announcement number CN212249119U. However, box-type rails cannot be formed in one piece; they need to be welded together from four steel plates. It is difficult for workers to ensure the consistency of the welding of each box-type rail during the welding process. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a box-type guide rail for the hydraulic climbing device of a tower building machine, which reduces the welding difficulty and ensures that the finished products of each box-type rail are consistent.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a box-type guide rail for a hydraulic climbing device of a tower building machine, including two side plates, with an intermediate plate between the two side plates. The intermediate plate is inserted into the side plates and then fixed by welding to form a box-type guide rail.

[0005] Preferably, the middle plate has plugs on both sides and sockets on the side plate that mate with the plugs.

[0006] Preferably, the middle plate is perpendicular to the side plate.

[0007] Preferably, the thickness of the plug is the same as the width of the socket.

[0008] Preferably, both the plug and the socket are rectangular.

[0009] Preferably, the outer end of the plug is chamfered.

[0010] Preferably, the middle plate and side plates are both made by laser cutting.

[0011] This utility model provides a box-type guide rail for a hydraulic climbing device of a tower construction machine, which has the following beneficial effects:

[0012] 1. Reduced Welding Difficulty: By using an interlocking and welding method between the middle plate and the side plates, the complex process of directly welding four steel plates is eliminated. Traditional methods for welding box-type tracks are difficult to control precisely in terms of the splicing angle and position of the four steel plates, requiring extremely high welding skills from workers. This patented interlocking structure pre-fixes the relative positions of each component during assembly, making the welding process simpler and more convenient, effectively reducing welding difficulty and minimizing product defects caused by improper welding operations.

[0013] 2. Ensuring Product Consistency: In the mass production of box-type guide rails, traditional welding methods, due to variations in manual operation, make it difficult to ensure that the size, shape, and structure of each box-type guide rail are completely consistent. This patented design utilizes precise laser cutting technology to fabricate the middle and side plates, and employs a standardized interlocking structure to ensure that each box-type guide rail has identical initial conditions during assembly, thereby significantly improving product consistency. This not only enhances the overall performance and stability of the tower crane but also facilitates subsequent installation, maintenance, and replacement work, reducing production and time costs.

[0014] 3. Improved Production Efficiency: By reducing welding difficulty and improving product consistency, the production process reduces rework and adjustment time due to welding errors, resulting in a smoother and more efficient overall production flow. The application of laser cutting technology also accelerates the manufacturing speed of parts, further improving production efficiency and helping companies gain a competitive edge in the market.

[0015] 4. Easy to install: The chamfer on the outer end of the plug on the middle plate makes it easier to insert the plug into the hole on the side plate during installation, reducing friction and jamming during installation, improving the convenience and speed of installation. Even non-professional technicians can easily complete the installation, reducing labor and training costs. Attached Figure Description

[0020] like Figure 1-3 As shown, a box-type guide rail for a hydraulic climbing device of a tower building machine includes two side plates 1 and an intermediate plate 2 between the two side plates 1. The intermediate plate 2 is inserted into the side plates 1 and then fixed by welding to form a box-type guide rail.

[0021] Preferably, the middle plate 2 is provided with plugs 3 on both sides, and the side plate 1 is provided with sockets 4 that cooperate with the plugs 3.

[0022] Preferably, the intermediate plate 2 is perpendicular to the side plate 1.

[0023] Preferably, the thickness of the plug 3 is the same as the width of the socket 4.

[0024] Preferably, both the plug 3 and the socket 4 are rectangular.

[0025] Preferably, the outer end of the plug 3 is chamfered. The chamfer facilitates the insertion of the plug into the socket.

[0026] Preferably, both the middle plate 2 and the side plate 1 are laser-cut. Compared to traditional punching and cutting, laser cutting is more precise and convenient.

[0027] In use, align the plug 3 of the middle plate 2 with the socket 4 of the side plate 1 for installation. After installation, use conventional welding techniques to weld the side plate 1 and the middle plate 2 together to form a box-type guide rail.

[0028] This patent aims to solve the technical challenges of box-type guide rails in the hydraulic climbing device of tower cranes. Traditional box-type rails are difficult to weld and have poor consistency. This patent adopts an innovative structure that uses a middle plate and side plate to be inserted and then welded. It utilizes laser cutting of the middle plate and side plate and designs matching plugs and sockets. The outer end of the plug is chamfered, which successfully reduces the welding difficulty, ensures the consistency of each box-type rail product, effectively improves the production quality and efficiency of box-type guide rails, and provides a reliable guarantee for the stable operation of tower cranes.
