Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe tower connection structure, and in particular to a connection structure for a high-strength power steel pipe tower. Background Technology

[0002] Steel pipe towers have low wind pressure resistance, high cross-sectional bending stiffness, simple structure, and clear force transmission, which can fully utilize the material's load-bearing capacity. On the one hand, this can reduce the weight of the tower and decrease the foundation force; on the other hand, it can enhance the ability to resist natural disasters under extreme conditions. When strength and stability calculation requirements are met, using steel pipe towers with a relatively small wind pressure shape coefficient can significantly reduce the wind load on the tower body.

[0003] The prior art patent CN217400506U discloses a connection structure for steel pipe towers, including an installation pipe. Both inner walls of the installation pipe are fitted with fixing boxes. Each fixing box contains a limiting component that penetrates and extends beyond the fixing box. Symmetrically distributed first limiting holes are formed on both sides of one end of the installation pipe. A connecting component is also fitted around the outer ring of the end of the installation pipe with the first limiting holes. This utility model proposes a connection structure for steel pipe towers that enables rapid connection and installation, greatly improving worker efficiency, reducing labor intensity, facilitating disassembly, and providing convenient use with strong practicality.

[0004] However, the existing connection methods for steel pipe towers generally use a large number of bolts and nuts for connection and fixation. The number of bolts and nuts ranges from a dozen to more than thirty sets. It requires employees to use tools to fix them, which is time-consuming and labor-intensive. Moreover, due to long-term use, the bolt fixing points may loosen and fall off, affecting the safety and making the fixation of the steel pipe towers not stable enough. Utility Model Content

[0024] Each of the twelve reinforcing plates 4 has a threaded groove inside. The reinforcing plates 4 are tightly attached to the steel pipe rod 1. Fastening bolts 7 are installed between the reinforcing plates 4 and the steel pipe rod 1. The fastening bolts 7 and the reinforcing plates 4 are engaged through the threaded grooves for fixing the reinforcing plates 4 and the steel pipe rod 1. The upper fixing structure 2 and the lower fixing structure 3 are sleeved on the outside of the steel pipe rod 1. Multiple reinforcing plates 4 at one end of the upper fixing structure 2 and the lower fixing structure 3 are tightly attached to the outside of the steel pipe rod 1. The fastening bolts 7 are used to engage and fix the reinforcing plates 4 and the steel pipe rod 1 for fixing.

[0025] The positioning component includes a positioning rod 11, with elastic protrusions 12 fixedly connected to the outside of the positioning rod 11. Multiple elastic protrusions 12 are arranged in a ring array. The positioning rod 11 is inserted into the positioning groove 18, and at the same time as insertion, it squeezes the elastic protrusions 12 and inserts them into the limiting groove 19 for fixing between the upper fixing structure 2 and the lower fixing structure 3. The positioning rod 11 on the lower end face of the upper fixing structure 2 is inserted into the positioning groove 18 inside the lower fixing structure 3 for fixing. At the same time as insertion, it squeezes the multiple elastic protrusions 12 on the outer wall, so that the elastic protrusions 12 are locked into the limiting groove 19 for fixing.

[0026] The fixing component includes a fixing block 14, with movable slots 15 on both the left and right sides inside the fixing block 14. Insert rods 17 are installed inside each of the two movable slots 15, and springs 16 are sleeved on the outside of each of the two insert rods 17.

As the U-shaped insert 8 is inserted into the slot 13, the insert rods 17 and springs 16... Contact with the U-shaped insert 8 is used for the synchronous compression of the insert rod 17 and the spring 16, and the insert rod 17 is inserted into the socket 10 for the reinforcement installation between the upper fixing structure 2 and the lower fixing structure 3. The U-shaped insert 8 on the lower end face of the second extension block 6 on the left and right sides of the upper fixing structure 2 is inserted into the slot 13 inside the two first extension blocks 5 for fixation. At the same time, both insert rods 17 contact the U-shaped insert 8 to compress the insert rod 17 and the spring 16 synchronously, and finally the insert rod 17 is inserted into the socket 10 for fixation. At the same time, the fixing block 14 is also snapped into the limiting slot 9 for fixation.

[0027] During operation, the upper fixing structure 2 and the lower fixing structure 3 are sleeved on the outside of the steel pipe rod 1, and multiple reinforcing plates 4 at one end of the upper fixing structure 2 and the lower fixing structure 3 are tightly attached to the outside of the steel pipe rod 1. The reinforcing plates 4 and the steel pipe rod 1 are fixed by interlocking and passing through the fastening bolts 7. The positioning rod 11 and multiple elastic protrusions 12 on the lower end face of the upper fixing structure 2 are inserted into the positioning groove 18 inside the lower fixing structure 3 for fixation, and the elastic protrusions 12 are all inserted into the limiting groove 9. The U-shaped inserts 8 on the lower end face of the second extension blocks 6 on the left and right sides of the upper fixing structure 2 are inserted into the slots 13 inside the two first extension blocks 5 for fixation. At the same time, the two insert rods 17 contact the U-shaped inserts 8, compressing the insert rods 17 and the spring 16 synchronously, and finally inserting the insert rods 17 into the insertion holes 10 for fixation. At the same time, the fixing block 14 is also inserted into the limiting groove 9 for fixation.

[0028] Through the above steps, by fitting both the upper fixing structure 2 and the lower fixing structure 3 onto the outside of the steel pipe pole 1, and by tightly attaching the reinforcing plate 4 to the steel pipe pole 1, and by reinforcing it with fastening bolts 7, its stability is improved. This solves the problem that the existing connection method of the steel pipe pole 1 is fixed by a large number of bolts, which can easily loosen over time, resulting in an unstable fixation of the steel pipe pole 1 and certain safety hazards.
