Description

Technical Field

[0001] The utility model belongs to the technical field of strengthening power transmission iron tower components, in particular to an emergency device for instability of power transmission iron tower components. Background Art

[0002] At present, in the construction and use of transmission towers, some of the components of the transmission tower are pressure-bearing parts, which bear stress along the length direction or axis direction, so that the entire transmission tower is in a stable state. When the stress in the length direction or axis direction borne by the pressure-bearing parts exceeds the threshold, the pressure-bearing parts will suddenly bend and break, resulting in instability. In general, the length of the pressure-bearing parts is relatively long, so that the pressure-bearing parts inevitably have some local micro-bends. When the pressure-bearing parts are subjected to external forces, they will also cause larger bends and bend damage at the micro-bends, thereby causing the collapse of the transmission tower. Therefore, there is an urgent need for an emergency device for instability of transmission tower components, which is used to strengthen the transmission tower components, improve their ability to withstand stress along the length direction or axis direction, avoid bending due to excessive force, and improve the strength of the transmission tower.

It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0029] The utility model discloses an emergency device for instability of a transmission tower component, such as Figure 1-9As shown, it includes an angle-adjustable clamping assembly 100, which includes two clamping members, which are relatively arranged on both sides of the transmission tower component, and the two clamping members are connected and fastened by multiple connecting bolts 200, and the two clamping members clamp the corresponding parts of the transmission tower component. The specific structure of the clamping member of the utility model is that the clamping member includes two clamping arms 101, and the ends of the two clamping arms 101 close to each other are hinged together, and at least two strip holes 107 are spaced apart along the width direction of each clamping arm 101, and each strip hole 107 extends along the length direction of the clamping arm 101, and one end of each connecting bolt 200 passes through the corresponding strip holes 107 on the two clamping members in turn, and a locking nut 300 is threadedly connected to the connecting bolt 200, and the angle-adjustable clamping assembly 100 is clamped on the transmission tower component by tightening the locking nut 300. The working principle and advantages of the utility model are as follows: the utility model uses an angle-adjustable clamping assembly 100 to strengthen the transmission tower component. Specifically, since the shape of the transmission tower component is various, the utility model adjusts the angles of the two clamping members in the angle-adjustable clamping assembly 100 so that the angle-adjustable clamping assembly 100 can adapt to the transmission tower component of this shape, that is, adjusts the angles of the two clamping arms 101 on each clamping member so that the two clamping arms 101 are adapted to the corresponding surface of the transmission tower component, and then A plurality of connecting bolts 200 are used to connect and tighten the clamping arms 101 corresponding to the two clamping members, so that the clamping arms 101 of the angle-adjustable clamping assembly 100 are tightly clamped on the corresponding surface of the transmission tower component, thereby enhancing the compression and bending resistance of the transmission tower component at this position; in summary, it can be seen that the utility model can effectively strengthen the transmission tower component, improve its ability to withstand stress along its length direction or axial direction, avoid bending due to excessive force, and improve the strength of the transmission tower.

[0030] As a preferred embodiment of the present invention, the two clamping arms 101 on the clamping member are hinged in two ways. The first way is as follows: Figure 2 , 3 As shown, at the ends of the two clamping arms 101 close to each other, hinge ears 103 are respectively constructed, and the two hinge ears 103 are hinged together through a hinge shaft 108; in this way, the angles of the two clamping arms 101 are passively adjusted, that is, the two clamping arms 101 are attached to the surface of the transmission tower component, and then connected and fastened by connecting bolts 200 and locking nuts 300, so that the angles of the two clamping arms 101 are locked, and the angles will not change due to the action of external forces. The second way is, Figure 1As shown, hinge ears 103 are respectively constructed at the ends of the two clamping arms 101 that are close to each other. The two hinge ears 103 are hinged together by adjusting screws 104, and a fastening nut 105 is threadedly connected to the adjusting screws 104; in this way, the angles of the two connecting arms are actively adjusted, that is, the angles of the two connecting arms are first adjusted so that the two connecting arms fit on the corresponding surfaces of the transmission tower component, and then the fastening nuts 105 are tightened to lock the angles of the two connecting arms, and then the two clamps are connected and fastened to the transmission tower component by connecting bolts 200 and locking nuts 300.

[0031] As a preferred embodiment of the present invention, there are two ways to open the strip-shaped hole 107. The first way is as follows: Figure 3 As shown, the strip hole 107 is provided on the clamping arm 101 and extends from the hinged end of the clamping arm 101 to the other end. In this way, the connection bolt 200 can be adjusted to extend into different positions of the strip hole 107 to clamp transmission tower components of different models, sizes and shapes. The second method is as follows: Figure 1 , 2 As shown, connecting ears 106 are respectively constructed at the ends of the two clamping arms 101 that are away from each other, and strip holes 107 are opened on the connecting ears 106; thus, this method can only perform clamping operations on transmission tower components with parameters such as size and model that are not much different.

[0032] As a preferred embodiment of the present invention, Figure 7 , 8 As shown, the transmission tower component is an angle steel 700, and the two clamping members are adjusted to a right angle shape respectively, and a right angle clamping opening 500 is formed between the two right angle clamping members, and the corresponding part of the angle steel 700 is located in the right angle clamping opening 500. One end of each connecting bolt 200 in this embodiment obliquely passes through the corresponding two strip-shaped holes 107. In order to enable the inclined connecting bolt 200 to effectively and firmly connect and fasten the two clamping members to the angle steel 700, the measures taken in this embodiment are as follows: two inclined pads 600 are mounted on the connecting bolt 200, and the two inclined pads 600 are respectively abutted on the end faces of the two parallel clamping arms 101 that are away from each other, and the locking nut 300 is locked on the end face of the corresponding inclined pad 600.

[0033] As a preferred embodiment of the present invention, Figure 4 , 5 As shown, the transmission tower component is a plate-like structure 900 , and the two clamping members are adjusted to straight shapes respectively, forming a strip-like clamping opening 400 between the two straight clamping members, and the corresponding part of the plate-like structure 900 is located in the strip-like clamping opening 400 .

[0035] As a preferred embodiment of the utility model, there are multiple angle-adjustable clamping assemblies 100, which are arranged at intervals along the length direction of the transmission tower component. In order to further improve the performance of the transmission tower component, Figure 5 , 6 As shown in FIG. 9 , a reinforcement member 1000 is provided on at least one side of the transmission tower component, and the reinforcement member 1000 extends along the length direction of the transmission tower component. Each angle-adjustable clamping assembly 100 clamps the corresponding part of the reinforcement member 1000 on the transmission tower component. Generally, the reinforcement member 1000 is a plate-shaped structure 900 or a rod-shaped structure. When the transmission tower component is a square rod-shaped structure 800, the present embodiment can reinforce two adjacent sides of the transmission tower component, and then the horizontal angle of the adjacent angle-adjustable clamping assemblies 100 is 90°, that is, one of the angle-adjustable clamping assemblies 100 clamps a reinforcement member 1000 on one side of the transmission tower component, and the other transmission tower component clamps another reinforcement member 1000 on another adjacent side of the transmission tower component, thereby preventing the transmission tower component from bending in other directions.

[0036] As a preferred embodiment of the present invention, Figure 1 , 2 As shown, in order to avoid relative movement between the clamping arm 101 and the transmission tower component or reinforcement 1000 in the clamped state, measures are taken to construct bite lines 102 on the two end faces of the clamping arm 101 close to and away from the transmission tower component.
