Description

Technical Field

[0001] This application relates to the technical field of transmission towers, and specifically to a transmission tower deviation correction device. Background Art

[0002] As an important facility for power transmission, the stability of a transmission tower is directly related to the reliability and safety of power supply. Due to factors such as geological conditions, soil changes, and groundwater levels, uneven settlement may occur in the tower foundation, resulting in tower inclination. Tower inclination may cause the transmission line to break, leading to power outages and even safety accidents.

[0003] Patent No. CN 218374084 U discloses a transmission tower deviation correction device, including a hydraulic cylinder, a limiting rod, a contact plate, a support plate, etc. By pulling two support plates, the insertion posts can be pulled out of the slots. The support plates can increase the contact area with the ground, making the support plates more stable when placed on the ground. Rotating the rotating block allows the threaded column to be inserted into the soil to position the cross plate and the support plates. Starting the hydraulic cylinder can jack up the top plate for deviation correction. The contact plate can be installed by inserting the screw into the horizontal pipe and the top plate. By contacting through the contact plate, it can prevent damage to the surface of the top plate and is not easy to replace.

[0004] However, in use, it has the following defects:

[0005] Although the hydraulic cylinder is used to jack up for deviation correction, there may be no suitable support points at the support seat of the transmission tower for support, and it is impossible to determine how much height should be lifted upward to reach the horizontal when jacking up, and additional measuring instruments are required to assist in construction, thus affecting the efficiency of deviation correction. Summary of the Utility Model

[0006] The purpose of this application is to provide a transmission tower deviation correction device, which solves the problem that although the hydraulic cylinder is used to jack up for deviation correction in the background art, there may be no suitable support points at the support seat of the transmission tower for support, and it is impossible to determine how much height should be lifted upward to reach the horizontal when jacking up, and additional measuring instruments are required to assist in construction, thus affecting the efficiency of deviation correction.

[0007] To achieve the above object, the present application provides the following technical solution: A transmission tower rectification device, comprising a base, a top plate, clamping blocks, force-applying rods and a rectangular ring. Two hydraulic cylinders are fixedly connected to the top end of the base. The top end of the hydraulic cylinder is fixedly connected to the top plate, and a cushion plate is movably clamped to the top end of the top plate. The top end of the cushion plate is fixedly connected to the clamping blocks. Three parallel through grooves are formed through the side wall of the clamping blocks, and the force-applying rods are movably inserted into the inner sides of the through grooves. A fixing block is connected to the center of the outer side wall of the base. The top end of the fixing block is fixedly connected to a socket rod. The top end of the socket rod is movably sleeved with a measuring rod, and scale lines are formed on the outer side wall of the measuring rod. The top end of the measuring rod is fixedly connected to the rectangular ring.

[0008] In this technical solution, the distance between the two bases is adjusted according to the telescopic rod, so that the clamping blocks contact both sides of the tower bracket. Then, the force-applying rods are inserted into the corresponding through grooves on the surfaces of the clamping blocks on both sides. At this time, the force-applying rods are located between the gaps of the supporting feet, and the steel of the supporting feet is all around them, which can be used as the best support points. The hydraulic cylinders are started to drive the top plate, the clamping blocks and the force-applying rods to rise, and the clamping blocks and the force-applying rods will lift and rectify the supporting feet, solving the problem that the lifting cannot be carried out due to the lack of support points. At the same time, through the socket rod, the measuring rod, the scale lines and the rectangular ring, when measuring, the measuring rod is pulled out from the socket rod, so that the rectangular ring is aligned with the through groove. When the force-applying rod is inserted into the through groove, it is also inserted into the rectangular ring at the same time, so that the measuring rod can rise and fall together. In this way, the lifting height can be recorded according to the scale lines during the lifting process of the hydraulic cylinder, and the degree of rectification can be known in time, without the need to use other equipment for separate measurement, improving the convenience and practicality of the device.

[0009] As an optional solution of the technical solution of the present application, the force-applying rod is parallel to the surface of the base, and the cross-section of the force-applying rod is consistent with the inner size of the rectangular ring.

[0010] As an optional solution of the technical solution of the present application, a plurality of threaded holes are horizontally and uniformly formed on the side wall of the top plate. A limiting bolt is threadedly connected to the outer side wall of the cushion plate. The limiting bolt penetrates through the surface of the cushion plate and is threadedly connected to the top plate through the threaded hole.

[0011] As an optional solution of the technical solution of the present application, rivets are detachably connected to both sides of the top end of the base.

[0012] As an optional solution of the technical solution of the present application, the socket rod is perpendicular to the surface of the base, and the measuring rod fits with the inside of the socket rod, so that it can remain vertical during the lifting process.

[0013] As an optional solution of the technical solution of the present application, a telescopic rod is fixedly connected to the side wall of the base on one side of the rivet, and the other end of the telescopic rod is fixedly connected to the side wall of another base with the same size specification.

[0014] Compared with the prior art, the beneficial effects of the present application are as follows:

[0015] 1. According to the telescopic rod of the present application, the distance between the bases on both sides is adjusted, so that the clamping blocks contact both sides of the iron tower support, and then the force-applying rod is inserted into the corresponding through grooves on the surfaces of the clamping blocks on both sides. At this time, the force-applying rod is located between the gaps of the supporting feet, and the surrounding of it is the steel of the supporting feet, which can be used as the best support points. The hydraulic cylinder is started to drive the top plate, the clamping blocks and the force-applying rod to rise, and the clamping blocks and the force-applying rod will lift and correct the deviation of the supporting feet, solving the problem that the lifting cannot be carried out due to the lack of support points.

[0016] 2. Through the socket rod, the measuring rod, the scale line and the rectangular ring of the present application, when measuring, the measuring rod is pulled out from the socket rod, so that the rectangular ring is aligned with the through groove. When the force-applying rod is inserted into the through groove, it is simultaneously inserted into the rectangular ring, so that the measuring rod can rise and fall together. In this way, the height of the lift can be read according to the scale line during the lifting process of the hydraulic cylinder, and the degree of deviation correction can be known in time, without the need to use other equipment for separate measurement, improving the convenience and practicability of the device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the following will be further elaborated in conjunction with specific embodiments.

[0023] Such as Figure 1As shown in the figure, a deviation rectification device for a transmission tower includes a base 1, a top plate 5, clamping blocks 9, a force application rod 11, and a rectangular ring 16. Two hydraulic cylinders 4 are fixedly connected to the top end of the base 1, and the top end of the hydraulic cylinder 4 is fixedly connected to the top plate 5. Rivets 2 are detachably connected to both sides of the top end of the base 1. A telescopic rod 3 is fixedly connected to the side wall of the base 1 on one side of the rivet 2, and the other end of the telescopic rod 3 is fixedly connected to the side wall of another base 1 with the same size specification. The telescopic rod 3 is not only used to adjust the distance between the bases 1, but also can keep the two side bases 1 parallel.

[0024] As Figure 1 and Figure 2 shown in the figure, a cushion plate 7 is movably clamped to the top end of the top plate 5, and a clamping block 9 is fixedly connected to the top end of the cushion plate 7. Three parallel through slots 10 are formed through the side wall of the clamping block 9, and a force application rod 11 is movably inserted into the inner side of the through slot 10. The force application rod 11 can be inserted into the gap of the support leg, so as to set a support point for lifting. The surface of the clamping block 9 is set as a downward inclined plane, which can not only increase the support for the force application rod 11, but also the lower part of the support leg of the tower is narrower, so it can fit the support leg better.

[0025] As Figure 1 and Figure 2 shown in the figure, a number of threaded holes 6 are horizontally and evenly formed in the side wall of the top plate 5. A limit bolt 8 is threadedly connected to the outer side wall of the cushion plate 7. The limit bolt 8 penetrates the surface of the cushion plate 7 and is threadedly connected to the top plate 5 through the threaded hole 6. The cushion plate 7 can be horizontally adjusted in position on the surface of the top plate 5, so as to facilitate the insertion of the force application rod 11.

[0026] As Figure 3 shown in the figure, a fixing block 12 is connected to the center of the outer side wall of the base 1. A socket rod 13 is fixedly connected to the top end of the fixing block 12. A measuring rod 14 is movably sleeved on the top end of the socket rod 13. A scale line 15 is formed on the outer side wall of the measuring rod 14. A rectangular ring 16 is fixedly connected to the top end of the measuring rod 14. The force application rod 11 is parallel to the surface of the base 1, and the cross section of the force application rod 11 is consistent with the inner size of the rectangular ring 16. The socket rod 13 is perpendicular to the surface of the base 1, and the measuring rod 14 fits inside the socket rod 13. The scale line 15 on the surface of the measuring rod 14 can quickly know the rising height.

[0027] During actual use, the distance between the two bases 1 is adjusted according to the telescopic rod 3 so that the clamping blocks 9 come into contact with both sides of the tower bracket. Then, the rivets 2 are installed to fix the base 1. Next, the force application rod 11 is inserted into the corresponding through grooves 10 on the surfaces of the two clamping blocks 9. At this time, the force application rod 11 is located between the voids of the support feet, and the steel of the support feet surrounds it, which can serve as the best support points. The hydraulic cylinder 4 is activated to drive the top plate 5, the clamping blocks 9, and the force application rod 11 to rise. The clamping blocks 9 and the force application rod 11 will then lift and correct the deviation of the support feet, solving the problem that the lack of support points makes it impossible to lift. At the same time, through the socket rod 13, the measuring rod 14, the scale line 15, and the rectangular ring 16, when measuring, the measuring rod 14 is pulled out from the socket rod 13 so that the rectangular ring 16 is aligned with the through groove 10. When the force application rod 11 is inserted into the through groove 10, it is simultaneously inserted into the rectangular ring 16. In this way, the measuring rod 14 can rise and fall together, and the height of the lift read according to the scale line 15 can be recorded during the lift of the hydraulic cylinder 4, and the degree of deviation correction can be known in a timely manner without the need to use other equipment for separate measurement, improving the convenience and practicality of the device.
