Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power transmission towers, and particularly relates to a power transmission tower reinforcing structure. BACKGROUND

[0002] A power transmission tower is an important device in a power transmission project. In order to ensure normal operation of power transmission, the power transmission tower should be stably fixed on the ground. However, a power transmission line built in a region rich in wind resources is threatened by typhoons all the year round, and the typhoons often cause the power transmission tower to collapse and the structure to be damaged. For a newly built tower, the design standard can be improved to improve the wind resistance, but for an old power transmission tower in operation, the wind resistance can only be improved by reinforcement and reconstruction.

[0003] At present, there are two reinforcing methods: the first method is to punch holes in the main material of the tower, reinforce the inner side and the outer side of the angle steel with steel plates, and connect the two by bolts. This method has a large construction difficulty, and because the main material is punched, the performance of the angle steel is changed, and the original stress structure of the power transmission tower is damaged. The second method is to weld a secondary main material on the main material of the tower. This method is more difficult to operate than the first method, and if the welding quality is not well controlled during the welding process, the strength of the main material will be directly reduced, and the effect will be doubled.

[0004] Therefore, it is a technical problem to be solved by those skilled in the art to design a new reinforcing scheme to improve the wind resistance of the power transmission tower structure. SUMMARY

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0028] like Figures 1 to 4 As shown, a preferred embodiment of the present invention provides a transmission tower reinforcement structure, which includes a tower body with four side walls. The four side walls are opposite to each other in pairs, and each side wall is connected to its opposite side wall by a traction device; that is, the present application has four traction devices.

[0029] The traction device includes a first traction rope and a second traction rope 15. The two ends of the first traction rope are respectively connected to two opposite side walls of the tower body. The first end 8 of the first traction rope is connected to the upper part of one side wall of the tower body, and the second end 5 successively passes around the first guide wheel 2 and the grooved wheel 16 fixed to the ground, and is connected to the middle of the other side wall of the tower body. The part where the first end 8 connects to the tower body is the first connecting section 3, which gradually moves away from the tower body from top to bottom. The part where the second end 5 connects to the tower body is the second connecting section 3. Section 19, the second connecting section 19 gradually deviates inward from top to bottom into the tower; and the groove wheel 16 is located in the middle of the lower end of the tower body. The groove wheel 16 is coaxially connected to a vertically arranged screw 17. The lower end of the screw 17 is threadedly connected to a threaded sleeve 18 fixed to the ground, and the upper end is connected to the top of the tower body through a second traction rope 15 located inside the tower body; wherein, both the first traction rope and the second traction rope 15 are in a taut state, and the first end is used to drive the screw to screw into the threaded sleeve, and the second end is used to drive the screw to screw out of the threaded sleeve.

[0030] The first guide wheel 2 can be away from the corresponding side wall, so that the lower end of the first end 8 gradually moves away from the tower body, and the lower end of the second end 5 gradually deviates to the inner side of the tower body, so that when the side wall connected by the first end 8 is the windward side, and the side wall connected by the second end 5 is the leeward side, the upper end of the tower body deforms and swings to pull the first traction rope, thereby pulling the leeward side of the tower body, to provide lateral support, and the support force can be automatically adjusted according to the wind force, and at the same time, the leeward side also acts on the first end 8 to generate a reverse pulling force to pull the upper end of the tower body to deviate to the windward side to resist the deflection of the upper end of the tower body.

[0031] In addition, the middle part of the first traction rope is wound around the wire groove wheel 16, so that when the side wall connected by the first end 8 is the windward side (i.e., the first end is under stress), the tower body deviates to the leeward side to pull the first traction rope, thereby driving the wire groove wheel 16 to rotate, driving the screw rod 17 to rotate to screw into the threaded sleeve 18, thereby pulling down the second traction rope 15 and pressing down the top of the tower body.

[0032] When the power transmission tower reinforcing structure provided by the application is applied, traction devices can be installed on the four side walls of the tower body to pull the side walls connected by the two ends of the first traction rope to resist the swing and deformation of the tower body, and the first traction rope can drive the wire groove wheel 16 to rotate, thereby pulling down the top of the tower body through the second traction rope 15 to form a pressing-down force, improving the connection strength of the tower body and the foundation 1 and further improving the anti-toppling and deformation capacity; in addition, the device does not need to change the original structure of the original tower body and is installed by an external method, which can avoid damaging the structure of the tower body and realize non-destructive installation.

[0033] Therefore, the installation of the traction device on the four side walls of the tower body can resist wind forces in all directions, effectively improve the anti-toppling capacity of the tower body, and has low implementation difficulty, is easy to implement non-destructive reconstruction of old towers, and has low overall reconstruction cost.

[0034] It should be noted that when the external wind force disappears, the wire groove wheel returns to the original position under the action of the deformation recovery of the first traction rope.

[0035] As shown in Figure 5 On the basis of the above embodiment, the ground is provided with a foundation 1, the guide wheel and the threaded sleeve 18 are fixed to the foundation 1, and the threaded sleeve 18 and the guide wheel are connected with the steel reinforcement frame in the foundation 1.

[0036] The foundation 1 can be poured with concrete, and the foundation 1 is provided with a steel reinforcement frame to effectively improve the structural strength, and the base of the guide wheel and the threaded sleeve 18 are welded and fixed to the steel reinforcement frame to realize force conduction to the foundation 1; it should be noted that the lower end of the threaded sleeve 18 is closed and embedded in the foundation 1, so that the screw rod 17 can be screwed in or out.

[0037] On the basis of the above-mentioned embodiments, the screw rod 17 is coaxially connected with the piston 20, the threaded sleeve 18 is coaxially connected with the cylinder sleeve 23, the lower end of the cylinder sleeve 23 is sealingly arranged, and the piston 20 is slidingly inserted into the cylinder sleeve 23; wherein the outer side of the piston 20 is provided with a coaxial annular groove, and an elastic sealing ring is assembled in the annular groove, the outer side of the elastic sealing ring is in contact with the inner wall of the cylinder sleeve 23, thereby forming a dynamic sealing cavity 22 in the cylinder sleeve 23, and the sealing cavity 22 is filled with lubricating grease.

[0038] The piston 20 and the cylinder sleeve 23 are slidingly fitted to ensure that the piston 20 can move along the axial direction of the cylinder sleeve 23. It should be noted that within the movement range of the piston 20, the piston 20 is always located in the cylinder sleeve 23, and the sealing cavity 22 formed between the cylinder sleeve 23 and the piston 20 is kept sealed through the cooperation of the elastic sealing ring, so as to avoid the leakage of lubricating grease; thereby preventing the rust or jam between the screw rod 17 and the threaded sleeve 18, so that the screw rod 17 can rotate flexibly, and the causes of rust or jam are, for example, long-term rain corrosion or foreign matter from the outside.

[0039] More specifically, the lower end side wall of the cylinder sleeve 23 is provided with a filling hole 21, so as to facilitate the filling of lubricating grease into the sealing cavity 22, and the filling hole 21 is threadedly connected with a screw plug, which can be sealed during non-filling period.

[0040] On the basis of the above-mentioned embodiments, the support column 10 located in the tower body is further included, the support column 10 is vertically arranged, the upper end of the support column 10 is connected with the top of the tower body through the high-strength spring 11, and the lower end is connected with the support 13 fixed to the ground.

[0042] The support 13 comprises a support table and a supporting leg arranged at the lower end of the support table, and the lower end of the supporting column 10 is fixed to the support table, so that the wire groove wheel 16 and the screw rod 17 are both located below the support table, avoiding the interference between the supporting column 10 and the wire groove wheel 16 and the screw rod 17, and the supporting column 10 and the second traction rope 15 can be arranged in a staggered manner; the upper end of the supporting column 10 is in contact with the top of the tower body through a strong spring to achieve support; when the wind blows, the first traction rope drives the wire groove wheel 16 to rotate, so that the screw rod 17 is screwed into the threaded sleeve 18, thereby realizing the downward pulling of the top of the tower body to increase the stability thereof; the tower body can have a slight deformation through the compression of the strong spring, and the frame of the tower body is conical, so that the frame of the tower body can be slightly deformed and bent outward to increase the downward pressure of the tower body, and the tower body is more stable; meanwhile, the supporting column 10 can cooperate with the strong spring to control the deformation range of the tower body, avoiding that the deformation is too large to cause the tower body to be damaged by pressure.

[0043] It should be noted that the support table is provided with a wire hole for the third traction rope 12 to pass through.

[0047] On the basis of the above embodiment, the groove bottom of the wire groove wheel 16 is provided with an anti-skid structure; the anti-skid structure can be anti-skid lines or can increase the roughness of the surface thereof; here, no specific limitation is made, as long as the function of increasing the friction between the first traction ropes wound on the wire groove wheel 16 can be achieved, and all are within the protection scope of the present application.

[0048] On the basis of the above embodiment, the second traction rope 15 of each traction device is connected to the adapter plate 14, and the adapter plate 14 is connected to the top of the tower body through the third traction rope 12.

[0049] The additional adapter plate 14 and the third traction rope 12 can be connected to the top of the tower body through the third traction rope 12, the length of the second traction rope 15 is reduced, the cost is saved, and the second traction rope 15 is prevented from being intertwined.

[0053] Specifically, the second guide wheel 4 is arranged on the inner side of the bottom of the tower body, and the base of the second guide wheel 4 is connected with the steel framework of the foundation 1.

[0054] It should be noted that the force is borne by the second guide wheel 4, so that the screw rod 17 is prevented from being damaged and failed due to bearing long-term load caused by the first traction extension and retraction wire slot wheel 16.
