Description

Technical Field

[0001] This utility model relates to the field of power steel pipe tower technology, specifically a reversible safety maintenance platform for power steel pipe towers. Background Technology

[0002] A power transmission steel pipe tower is a lattice-type tower, with its main components made of steel pipes and other components made of steel pipes or structural steel. It serves as a support structure for overhead transmission lines to support conductors and lightning protection wires, ensuring that the conductors meet the distance requirements to the ground and ground objects, and can withstand the loads of the conductors, lightning protection wires, and the tower itself, as well as external loads.

[0003] The existing patent (publication number: CN221761292U) discloses a reversible safety maintenance platform for power steel pipe towers. By stably installing the device on the steel pipe tower, the combined action of sliding wheels and rotating rods provides support when the horizontal plate moves, preventing swaying when workers move the platform. By incorporating a reversing motor, the horizontal plate can be moved to a different position, eliminating the need to rearrange the maintenance device and thus achieving time and labor savings.

[0004] However, the above technical solution still has certain drawbacks. The device is fixed on the steel pipe tower and can only be used for maintenance of a single steel pipe tower. If the device is installed on multiple steel pipe towers, it will cost a lot. At the same time, the space for maintenance on the platform is relatively limited, which will increase the difficulty of maintenance and reduce work efficiency. Therefore, a rotating safety maintenance platform for power steel pipe towers is proposed. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a reversible safety maintenance platform for power steel pipe towers to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a reversible safety maintenance platform for power steel pipe towers, comprising a first semicircular seat, a second semicircular seat abutting against one side of the first semicircular seat, a semicircular block fixed to the top of both the first and second semicircular seats, and a support rod fixed to the side of the top of both the first and second semicircular seats near the semicircular block, with two sets of fixed seats at the top of the support rod, and an annular block rotatably connected to the inner wall of both sets of fixed seats, and an adjustment component at the top of one set of annular blocks;

[0007] The adjustment assembly includes a support plate fixed to one side of a set of annular blocks. A maintenance platform is slidably connected to the top of the support plate. A groove is provided inside the maintenance platform. A movable frame is slidably connected inside the groove. Square slots for the movable frame to move horizontally are provided inside both sets of fixed seats.

[0008] As a preferred technical solution, a plurality of insert blocks are fixed on one side of the first semicircular seat, and a slot for matching insert blocks is provided on one side of the second semicircular seat.

[0009] As a preferred technical solution, the first semicircular seat, the second semicircular seat, the two sets of fixed seats, and the two sets of annular blocks are all provided with bolt fixing plates on the side near the end face.

[0010] As a preferred technical solution, an annular column is fixed to the top of both sets of fixing seats.

[0011] As a preferred technical solution, the bottom ends of the two sets of annular blocks are fixed with annular strips, and the fixed base has an annular groove inside for the annular strips to slide.

[0012] As a preferred technical solution, sliders are fixed on both sides of the bottom of the mobile frame, and a sliding groove is provided on the support plate for the sliders to move, the sliding groove extending to the bottom of the inner wall of the square groove.

[0013] As a preferred technical solution, the side of the square groove away from the movable frame is provided with a baffle connected to the fixed base.

[0014] In summary, the present invention has the following main advantages:

[0015] This invention enables the maintenance platform to rotate via the inner walls of two sets of fixed seats by pulling the annular column, allowing for comprehensive maintenance of the steel pipe tower and improving maintenance efficiency. When it is necessary to repair or replace the crossarms on the steel pipe tower, the internal space of the maintenance platform is increased by pushing the movable frame, effectively reducing the probability of contact between maintenance personnel and equipment / tools, lowering the risk of collisions or mechanical damage due to operational errors, and improving safety. After maintenance is completed, the first and second semicircular seats can be removed, facilitating subsequent maintenance of the steel pipe tower by the staff. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] The embodiments of this utility model will be described below based on its overall structure.

[0024] A type of reversible safety maintenance platform for power steel pipe towers, such as Figure 1-4 As shown, it includes a first semicircular seat 100, a second semicircular seat 110 abutting against one side of the first semicircular seat 100, a semicircular block 120 fixed at the top of both the first semicircular seat 100 and the second semicircular seat 110, and a support rod 130 fixed at the top of both the first semicircular seat 100 and the side of the second semicircular seat 110 near the semicircular block 120. The top of the support rod 130 is provided with two sets of fixing seats 140, and an annular block 150 is rotatably connected to the inner wall of both sets of fixing seats 140. An adjustment component 200 is provided at the top of one set of annular blocks 150.

[0025] The adjustment assembly 200 includes a support plate 210 fixed to one side of a set of annular blocks 150. A maintenance platform 220 is slidably connected to the top of the support plate 210. A groove 221 is provided inside the maintenance platform 220. A movable frame 230 is slidably connected inside the groove 221. Square grooves 251 for the movable frame 230 to move horizontally are provided inside both sets of fixed seats 140.

[0026] By fitting the first semicircular seat 100 and the second semicircular seat 110 together around the steel pipe tower, and then fixing the bolt fixing plates 170 on both sides with bolts, the fixing of the first semicircular seat 100 and the second semicircular seat 110 is completed. Then, the bolt fixing plates 170 on the two sets of fixing seats 140 and the two sets of annular blocks 150 are bolted in sequence. Workers enter the maintenance platform 220, and using lifting equipment, the first semicircular seat 100 and the second semicircular seat 110 are raised along the steel pipe tower. By pulling the annular column 160, the workers can rotate the maintenance platform 220 via the annular blocks 150 on the inner walls of the two sets of fixing seats 140, thereby enabling... Comprehensive overhaul of the steel pipe tower improves maintenance efficiency. When it is necessary to repair or replace the crossarms on the steel pipe tower during maintenance, the movable frame 230 is pushed and slid out of the maintenance platform 220 until it moves into the square groove 251 and fits against the baffle 250. This increases the space inside the maintenance platform 220, effectively reducing the probability of contact between maintenance personnel and equipment / tools, lowering the risk of collisions or mechanical damage caused by operational errors, and improving safety. After maintenance is completed, the first semicircular seat 100 and the second semicircular seat 110 can be removed, facilitating subsequent maintenance of the steel pipe tower.

[0027] Please refer to this carefully. Figure 1 and Figure 2 The first semicircular seat 100 has multiple sets of insert blocks 111 fixed on one side, and the second semicircular seat 110 has a slot 112 for matching the insert blocks 111 on one side.

[0028] The cooperation between the insert block 111 and the slot 112 makes the first semicircular seat 100 and the second semicircular seat 110 fit together more stably.

[0029] Please refer to this carefully. Figure 3 The first semicircular seat 100, the second semicircular seat 110, the two sets of fixed seats 140 and the two sets of annular blocks 150 are all provided with bolt fixing plates 170 on the side near the end face. The top of the two sets of fixed seats 140 is fixed with annular columns 160, and the bottom of the two sets of annular blocks 150 is fixed with annular strips 151. The fixed seat 140 has an annular groove 152 for the annular strips 151 to slide inside.

[0030] By setting up the annular column 160, it is easy for staff to reach out and make the maintenance platform 220 rotate around the steel pipe tower.

[0031] Please refer to this carefully. Figure 3 and Figure 4 The movable frame 230 has sliders 240 fixed on both sides of its bottom end. The support plate 210 has a groove 241 for the sliders 240 to move. The groove 241 extends to the bottom of the inner wall of the square groove 251. The side of the square groove 251 away from the movable frame 230 has a baffle 250 connected to the fixed seat 140.

[0032] Through the cooperation of slider 240 and slide groove 241, the movable frame 230 can move more stably to one side of square groove 251.

[0033] In use, the first semicircular seat 100 and the second semicircular seat 110 are fixed with bolts, allowing the first and second semicircular seats 100 and 110 to rise along the steel pipe tower. Workers can pull the annular column 160 to rotate the maintenance platform 220 via the annular block 150 on the inner wall of the two sets of fixed seats 140, thus enabling all-around maintenance of the steel pipe tower and improving maintenance efficiency. When it is necessary to repair or replace the crossarms on the steel pipe tower, the movable frame 230 is pushed to slide from inside the maintenance platform 220. The mobile frame 230 is moved out until it enters the square groove 251 and fits against the baffle 250, which increases the space inside the maintenance platform 220. This effectively reduces the probability of contact between maintenance personnel and equipment / tools, lowers the risk of collisions or mechanical damage caused by operational errors, and improves safety. After maintenance is completed, the first semicircular seat 100 and the second semicircular seat 110 can be removed, making it convenient for staff to carry out subsequent maintenance on the steel pipe tower. The parts not involved in this device are the same as or can be implemented using existing technologies.
