Description

Technical Field

[0001] The present invention belongs to the technical field of transmission tower maintenance and safety, and particularly relates to a free-position and angle connecting piece for the lateral support of a transmission tower. Background Art

[0002] At present, a large number of active transmission towers in China are still built according to the old regulations. In the face of natural disasters such as wind disasters and ice disasters, they are prone to block shear failure or overall collapse failure and cannot meet the requirements of safe use. According to the characteristics of the structural failure mechanism, seeking an effective reinforcement method for the currently under-capacity transmission towers for the weak members has become the most economical and efficient choice. At present, in the reinforcement methods of transmission towers, the commonly used welding or bolt connection will seriously weaken the compressive bearing capacity of the original members. At the same time, according to the requirements of the members to be reinforced, there is a problem that the connection angle of the members is an arbitrary angle.

[0003] Therefore, there is an urgent need for a reinforcement method that does not damage the raw materials, can clamp at any angle, and is convenient for construction to solve the existing technical problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a free-position and angle connecting piece for the lateral support of a transmission tower, which is used to solve the problem that the structural strength of the original tower is damaged by drilling when installing the lateral support angle steel in the maintenance of the transmission tower in the prior art.

[0005] The technical solution adopted by the present invention is to provide a free-position and angle connecting piece for the lateral support of a transmission tower, including a tower angle steel. A first right-angle clamp is arranged on the inner side of the tower angle steel, and a second right-angle clamp symmetrical to the first right-angle clamp is arranged on the outer side of the tower angle steel. The second right-angle clamp and the first right-angle clamp jointly clamp the tower angle steel. A round hole is provided on one side of the first right-angle clamp and the second right-angle clamp for clamping the tower angle steel, and the round hole is locked by connecting bolts. Arc-shaped holes are respectively provided on the other sides of the first right-angle clamp and the second right-angle clamp, and the arc-shaped holes on the two right-angle clamps are centrosymmetric;

[0006] The first right-angle clamp and the second right-angle clamp with the same structure as that on the tower angle steel are arranged on the angle steel to be connected;

[0007] The arc-shaped holes on the tower angle steel and the angle steel to be connected are connected and locked by arc-shaped hole connecting bolts, and the angle steel to be connected can rotate relative to the tower angle steel along the arc-shaped holes.

[0008] Gaskets are respectively arranged below the sides of the first right-angle clamp and the second right-angle clamp where the arc-shaped holes are provided. The hardness of the gaskets is lower than that of the angle steel, and the thickness of the gaskets is equal to the thickness of the angle steel.

[0009] An elastic gasket is provided between the sides of the first right-angle splint and the second right-angle splint with round holes and the iron tower angle steel.

[0010] The arc-shaped holes are multi-layer arc-shaped holes.

[0011] Through the above design, the present invention can bring the following beneficial effects:

[0012] 1. By providing right-angle splints and bolt holes on the right-angle splints, directly drilling holes on the iron tower angle steel is avoided, the original structure of the transmission tower is not damaged, and the structure of the transmission tower is ensured to be stable and safe;

[0013] 2. By providing arc-shaped holes on the right-angle splints, horizontal support at any angle and position can be realized as needed;

[0014] 3. The connection method of bolts ensures quick and stable installation and rapid operation;

[0015] 4. All components are easy to manufacture, with low cost, and are convenient for manufacturing and popularization;

[0016] 5. Similar components can be interchanged, reducing reserves and carrying, and can also be used for connecting and installing other similar special-shaped parts. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

[0021] The present invention will be further described below in conjunction with the drawings and specific embodiments:

[0022] As Figures 1-3As shown in the figure, a first right-angle splint 1 is provided on the inner side of the tower angle steel 2, and a second right-angle splint 4 symmetrical to the first right-angle splint 1 is provided on the outer side. An elastic gasket 8 is located between the two right-angle splints and the tower angle steel 2 to achieve support for clamping the tower angle steel 2. The first right-angle splint 1 and the second right-angle splint 4 jointly clamp the tower angle steel 2.

[0023] Round holes 9 are provided on one side of the first right-angle splint 1 and the second right-angle splint 4, and arc-shaped holes 10 are provided on the other side. The arc-shaped holes 10 can be multi-layered. Among them, the round holes 9 on the first right-angle splint 1 and the second right-angle splint 4 are connected by round-hole connection bolts 6 for clamping the angle steel. The arc-shaped holes 10 are connected to the corresponding arc-shaped holes 10 of another clamped angle steel through arc-shaped hole connection bolts 3.

[0024] For the arc-shaped holes 10 of the two right-angle splints, according to the thickness of the clamped angle steel, the respective arc-shaped holes 10 of the first right-angle splint 1 and the second right-angle splint 4 are designed to be concentric.

[0025] Gaskets 7 are provided below the arc-shaped holes 10 of the two right-angle splints. They cooperate with the right-angle splints, have a hardness lower than that of the angle steel, a thickness equal to the thickness of the angle steel, and are in direct contact with the gaskets 7 of the right-angle splints of another angle steel.

[0026] The tower angle steel 2 and the angle steel to be connected 5 are respectively clamped and fixed by two right-angle splints, an elastic gasket 8, and round-hole connection bolts 6. Gaskets 7 are respectively installed below the arc-shaped holes 10 of the right-angle splints of the two angle steels, and fixed clamping is achieved through arc-shaped hole connection bolts 3. The arc-shaped holes 10 of the corresponding right-angle splints can be concentrically installed to achieve concentric free-angle rotation of the two angle steels, and stable installation of multiple bolts in multiple layers is achieved through the multi-layer arc-shaped hole design.

[0027] The present invention can adapt to the free-angle installation of special-shaped cross-section metal components such as angle steels under various conditions. Through clamping with splints and elastic gaskets corresponding to the cross-section, the design and assembly of concentric circular arc holes are carried out, and free-angle installation can be quickly carried out, having the advantages of strong standardization, low cost, good interchangeability, easy portability, and easy promotion.

[0028] The implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and are all included in the protection scope of the present invention.
