Description

Technical Field

[0001] The invention relates to the technical field of electric power engineering, in particular to a repair tower for a power transmission line. Background Art

[0002] The emergency repair tower is a tower structure used to support high-altitude power transmission lines. Its main purpose is to temporarily support the repair of power transmission towers, so that the power transmission lines can be supported when the power transmission towers are damaged or collapsed, and to prevent the power transmission lines from sagging and contacting the ground.

[0003] Existing emergency repair towers are mainly divided into two types, namely, integrated type and spliced ​​type. The integrated type is usually small and medium-sized for easy transportation, and the spliced ​​type has large, medium and small sizes. After being transported to the site in parts, they are spliced ​​and assembled into emergency repair towers, which is convenient for transportation of large and small emergency repair towers.

[0004] Regardless of the type of emergency repair tower, a foundation must be set up during construction. If a foundation is not set up, it is easy to cause the emergency repair tower to collapse. However, the construction of the foundation is mainly pouring concrete, which makes the construction of the emergency repair tower very time-consuming and labor-intensive. It is necessary to carry out operations such as digging pits, supporting molds, tying reinforcement, pouring, vibrating, curing, and removing molds in sequence, which prolongs the time for emergency repairs and makes it difficult to quickly build the foundation. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a repair tower for a power transmission line to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a repair tower for a power transmission line, comprising an embedded box, a support frame fixed inside the embedded box, ground anchors passing through both sides of the bottom of the embedded box, and a cover plate connected to the top of the embedded box; a first hydraulic cylinder and a guide rail are respectively arranged on one side of the top of the cover plate, and the output end of the first hydraulic cylinder is connected to a slide, a second hydraulic cylinder is installed on the top of the slide, and the output end of the second hydraulic cylinder is connected to a clamping plate.

[0007] By adopting the above technical scheme, a pit is dug in the ground in advance and a ground anchor is driven into the pit, and then the embedded box is placed in the pit and the ground anchor is passed through the embedded box. The wavy lines on the surface of the embedded box are used to thicken and reinforce the area passing through the ground anchor, and secondly, to increase the contact area between the embedded box and the surrounding ground to avoid lateral displacement of the embedded box. Then, the heavy objects such as gravel, soil or construction waste just dug out can be poured into the embedded box to achieve a counterweight effect. The ground anchor plus the embedded box counterweight can effectively avoid the subsequent collapse of the emergency tower. Then, the cover plate is placed on the top of the embedded box and the nut is tightened on the ground anchor to limit the embedded box and the cover plate. If the environment of the emergency tower construction area is relatively harsh and the lifting equipment is difficult to enter or cannot enter, a tower bracket can be placed on the top of the cover plate first. At this time, the slide, the second hydraulic cylinder and the clamp are driven to move horizontally by the first hydraulic cylinder. After the clamp is moved horizontally, the tower bracket is clamped and limited, and then the tower top frame is placed on the top of the tower bracket and fastened by the first bolt and nut. At this time, the inclined cable, insulator and other structures can be installed on the tower top frame. The second hydraulic cylinder is then used to drive the clamping plate to move up, so that the tower support and the tower top frame are moved up. At this time, other tower top frames can continue to be placed on the top of the cover plate, and multiple tower top frames can be fastened together by the first bolts and nuts. At the same time, the lowest tower support and the cover plate are fastened by the second bolts. After that, the first hydraulic cylinder and the second hydraulic cylinder are closed to make the slide and the clamping plate move away from the tower support, and then the first hydraulic cylinder is opened to make the slide, the second hydraulic cylinder and the clamping plate move laterally so that the clamping plate clamps the lowest tower support. At this time, the second bolt is removed to end the limit between the tower support and the cover plate. After that, the second hydraulic cylinder can be jacked up, the tower support is placed, the first bolt and the second bolt are installed, the first hydraulic cylinder and the second hydraulic cylinder are closed to reset, the first hydraulic cylinder is opened to clamp the tower support, the second bolt is removed, and the second hydraulic cylinder is lifted up, so as to build the repair tower. Finally, the lowest tower support and the cover plate are fastened together by the second bolt, and the lowest tower support is clamped and limited by the clamping plate, so as to complete the construction work.

[0008] Furthermore, the cover plate is detachably connected to the embedded box via a ground anchor, and the cover plate is connected to the top of the support frame.

[0009] By adopting the above technical solution, the construction workers dig a hole in the ground in advance and drive in a ground anchor. Then, the construction workers put the embedded box into the hole and pass the ground anchor through the embedded box. Then, the construction workers put the cover plate on the top of the embedded box and tighten the nut on the ground anchor to limit the embedded box and the cover plate.

[0010] Furthermore, the embedded box is wavy all around.

[0011] By adopting the above technical solution, the wavy texture on the surface of the embedded box can not only thicken and reinforce the area passing through the anchor, but also increase the contact area between the embedded box and the surrounding ground to avoid lateral displacement of the embedded box.

[0012] Furthermore, a plurality of ground anchors are provided, and the plurality of ground anchors are distributed in a "mouth" shape.

[0013] By adopting the above technical solution and increasing the number of ground anchors, the contact area between the embedded box and the ground and between the cover plate and the embedded box is increased, thereby improving the structural stability and avoiding the subsequent collapse of the emergency repair tower.

[0014] Furthermore, a tower bracket is connected to the middle of the top of the embedded box via a second bolt, and a tower top frame is connected to the top of the tower bracket via a first bolt.

[0015] By adopting the above technical solution, the construction workers then place the tower top frame on the top of the tower support and fasten it with the first bolts and nuts. At this time, structures such as inclined cables and insulators can be installed on the tower top frame, and the lowest tower support and the cover plate can be fastened with the second bolt.

[0016] Furthermore, the tower bracket and the first bolts are both provided in multiple groups, and the multiple groups of tower brackets and the first bolts are distributed at equal distances.

[0017] By adopting the above technical solution, a plurality of tower supports are overlapped to facilitate the construction of a high-height repair tower, thereby preventing the transmission line from contacting the ground.

[0018] Furthermore, the slide is slidably connected to the guide rail.

[0019] By adopting the above technical solution, the first hydraulic cylinder drives the slide, the second hydraulic cylinder and the clamping plate to move laterally, and the clamping plate clamps the tower support to a limited position after the laterally displacement.

[0020] Furthermore, the clamping plate is in contact with the tower support, and the cross section of the clamping plate is in a "C" shape.

[0021] By adopting the above technical solution, since the cross section of the clamping plate is C-shaped, the contact area between the clamping plate and the tower support is increased, and the front, rear and side positions can be limited, thereby improving the clamping stability.

[0022] Furthermore, there are two clamping plates and two sliding tables, and the two clamping plates and two sliding tables are arranged in a mirror image.

[0023] By adopting the above technical solution, the tower support is clamped and limited by two clamping plates, thereby preventing the tower support from being displaced forward, backward, left, right, or collapsing.

[0024] Furthermore, the first hydraulic cylinder and the second hydraulic cylinder are provided in plurality and divided into two groups, and the two groups of the first hydraulic cylinder and the second hydraulic cylinder are both arranged in a mirror image.

[0025] By adopting the above technical solution, the number of the first hydraulic cylinder and the second hydraulic cylinder is increased, thereby increasing the pressure that the first hydraulic cylinder and the second hydraulic cylinder can withstand, thereby avoiding the phenomenon that the structure is too heavy to be lifted.

[0026] In summary, the present invention mainly has the following beneficial effects:

[0027] 1. The present invention, through the arrangement of the embedded box, cover plate, ground anchor and support frame, digs a pit in the ground in advance and drives the ground anchor, then puts the embedded box into the pit and makes the ground anchor pass through the embedded box, and the wavy lines on the surface of the embedded box are used to thicken and reinforce the area through the ground anchor, and to increase the contact area between the embedded box and the surrounding ground to avoid lateral displacement of the embedded box, and then the freshly dug gravel soil or heavy objects such as construction waste can be poured into the embedded box to achieve the counterweight effect, and the ground anchor plus the embedded box counterweight can effectively avoid the subsequent collapse of the emergency repair tower, and then the cover plate is placed on the top of the embedded box and the nut is tightened on the ground anchor to limit the embedded box and the cover plate; no operations such as supporting formwork, tying reinforcement, pouring and vibrating, curing, and demolding are required; the time-consuming construction of the foundation is effectively reduced, thereby speeding up the construction of the emergency repair tower, and the support is stable to avoid the collapse of the emergency repair tower;

[0028] 2. The present invention provides a first hydraulic cylinder, a slide, a guide rail, a second hydraulic cylinder and a clamping plate. If the environment of the repair tower construction area is relatively harsh and it is difficult or impossible for lifting equipment to enter, a tower support can be placed on the top of the cover plate first. At this time, the slide, the second hydraulic cylinder and the clamping plate are driven to move laterally by the first hydraulic cylinder. After the clamping plate is laterally moved, the tower support is clamped and limited. Then, the tower top frame is placed on the top of the tower support and fastened by the first bolts and nuts. At this time, structures such as inclined cables and insulators can be installed on the tower top frame. Then, the clamping plate is driven to move up by the second hydraulic cylinder, so that the tower support and the tower top frame are moved up. At this time, other tower top frames can continue to be placed on the top of the cover plate, and multiple tower top frames are fastened together by the first bolts and nuts. At the same time, the lowest tower support and the cover are fastened by the second bolts. The plate is tightened, and then the first hydraulic cylinder and the second hydraulic cylinder are closed to make the slide and the clamping plate move away from the tower support, and then the first hydraulic cylinder is opened to make the slide, the second hydraulic cylinder and the clamping plate move laterally, so that the clamping plate clamps the lowest tower support. At this time, the second bolt is removed to end the limit between the tower support and the cover plate. After that, the second hydraulic cylinder can be used for lifting, placing the tower support, installing the first bolt and the second bolt, closing the first hydraulic cylinder and resetting the tower support, opening the first hydraulic cylinder to clamp the tower support, removing the second bolt, and lifting the second hydraulic cylinder to build the emergency tower. Finally, the lowest tower support and the cover plate are fastened together by the second bolt, and the lowest tower support is clamped and limited by the clamping plate to complete the construction work; the emergency tower can also be built without lifting equipment.

[0040] Embodiment 2:

[0041] On the basis of the above-mentioned embodiment 1, in order to avoid the phenomenon that the emergency repair tower is difficult to build due to the harsh environment in the construction area of ​​the emergency repair tower, the following settings are now adopted.

[0043] The implementation principle of the present invention is as follows: first, the construction workers dig a pit on the ground in advance and drive in the ground anchor 3, then the construction workers put the embedded box 1 into the pit and make the ground anchor 3 pass through the embedded box 1, the wavy lines on the surface of the embedded box 1 are used to thicken and reinforce the area that passes through the ground anchor 3, and secondly, to increase the contact area between the embedded box 1 and the surrounding ground to avoid lateral displacement of the embedded box 1, then the construction workers can pour the freshly dug gravel and soil or the transported construction waste and other heavy objects into the embedded box 1 to achieve the counterweight effect, and the ground anchor 3 plus the embedded box 1 counterweight can effectively avoid the collapse of the subsequent emergency repair tower, then the construction workers put the cover plate 2 on the top of the embedded box 1 and tighten the nut on the ground anchor 3 to limit the embedded box 1 and the cover plate 2;

[0044] After the construction of the base consisting of the embedded seat, the cover plate 2, the anchor 3 and the support frame 4 is completed, the construction personnel can start the construction of the emergency tower. If the environment of the emergency tower construction area is relatively harsh and the lifting equipment is difficult to enter or cannot enter, the construction personnel can first place a tower support 5 on the top of the cover plate 2. At this time, the construction personnel start the first hydraulic cylinder 7, and drive the slide 8, the second hydraulic cylinder 10 and the clamping plate 11 to move horizontally through the first hydraulic cylinder 7. After the clamping plate 11 moves horizontally, the tower support 5 is clamped and limited.

At this time, the construction workers can continue to place other tower top frames 6 on the top of the cover plate 2, and fasten multiple tower top frames 6 together through the first bolts 12 and nuts. At the same time, the construction workers fasten the lowest tower support 5 to the cover plate 2 through the second bolts 13 to prevent the tower support 5 from collapsing due to loss of limit when the clamping plate 11 is away from the tower support 5. Afterwards, the construction workers close the first hydraulic cylinder 7 and the second hydraulic cylinder 10 to move the slide 8 and the clamping plate 11 away from the tower support 5. The construction workers start the first hydraulic cylinder 7 again to move the slide 8, the second hydraulic cylinder 10 and the clamping plate 11 laterally, so that the clamping plate 11 clamps the lowest tower support 5. At this time, the construction workers remove the second bolts 13 to end the limit between the lowest tower support 5 and the cover plate 2.
