Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, specifically to a steel pipe tower support fixing device. Background Technology

[0002] Steel pipe towers are commonly used in my country's power transmission system. They are constructed by connecting multiple sections of steel pipes with flanges. The pipe sections are connected using multiple sets of bolts to secure the flanges at both ends. The power lines are not directly connected to the surface of the tower but are supported by a support structure. The power lines are then placed on the side support structure connected to the support structure. However, existing support structures typically use two semi-circular structures connected by bolts and fixed to the tower. When the bolts loosen, the support structure is prone to slippage.

[0003] A search of the China Patent Network reveals a plug-in type steel pipe tower support fixing device disclosed in Patent Announcement No. CN205875871U. This device includes a first semi-circular clamp, a second semi-circular clamp, a front locking nut, a rear locking nut, a screw, an adapter plate, an outer limiting block, a slider, a guide rail plate, and an elastic limiting mechanism. Both ends of the first semi-circular clamp have first extensions, and both ends of the second semi-circular clamp have second extensions. The first and second extensions are locked and clamped onto the screw by the front and rear locking nuts. The outer limiting block consists of an outer baffle and an outer connecting plate, which are integrally formed. The outer connecting plate is fixedly connected to the adapter plate. A positioning block is provided at the end of the screw, and a lower protrusion is provided at the end of the positioning block. The adapter plate has a fixing hole matching the lower protrusion, and the lower protrusion passes through the fixing hole and presses against the inner wall of the outer baffle. The above structure uses only bolts for fixing, which can easily lead to the pole slipping off when the bolts become loose. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a steel pipe tower scaffold fixing device to solve the technical problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel pipe tower support fixing device, comprising a clamp body, wherein the clamp body forms an annular clamp by connecting a first semi-arc sleeve and a second semi-arc sleeve, wherein an arc cavity is formed within the first and second semi-arc sleeves, and an inner arc plate is slidably provided within the arc cavity, wherein a notch is formed at the upper and lower ends of the inner arc plate near the end, wherein a gradually rising arc strip is fixed within the notch, wherein a driven step block is slidably provided on the inclined upper surface of the gradually rising arc strip, wherein a roller sliding within the notch is fixed at the bottom of the driven step block, and wherein multiple sets of irregular grooves are formed on the curved inner wall of the inner arc plate, wherein a ball head rod extending to the outside of the first semi-arc sleeve is fitted within each set of irregular grooves, and an arc-shaped abutment plate abutting against the support rod is fixed at the end face of the ball head rod located outside the first semi-arc sleeve.

[0006] As a preferred technical solution, the end faces of the first and second semi-circular sleeves are provided with relief grooves, the other ends of the first and second semi-circular sleeves are protrusions, and the upper and lower ends of the clamp body and the second semi-circular sleeves are provided with bolts that penetrate into the protrusions.

[0007] As a preferred technical solution, a storage groove is provided at the position where the inner curved wall of the first semi-arc sleeve contacts the arc-shaped abutment, and a circular channel is provided in the storage groove that communicates with the arc cavity and allows the ball head rod to slide.

[0008] As a preferred technical solution, two sets of ball-head constraint rods are fixed on the curved outer wall of the ball-head rod, and shallow grooves for constraining the irregular groove are opened on the upper and lower inner walls of the irregular groove.

[0009] As a preferred technical solution, the inclined surface of the gradually rising arc strip is provided with a channel for the roller to slide, and the inner wall of the channel is provided with a guide groove for the roller to roll at an angle.

[0010] As a preferred technical solution, the top of the driven step block is provided with a threaded hole that matches the bolt.

[0011] As a preferred technical solution, both the curved outer walls of the first and second semi-circular sleeves are fixed with horizontal arms, and the top of the horizontal arms is fixed with a bracket for mounting wires.

[0012] In summary, the present invention has the following main advantages:

[0013] This utility model uses two sets of staggered semi-circular sleeves to easily fit onto the outer wall of the pole. At the same time, the bolts that lock the two sets of semi-circular sleeves allow the inner arc plate to extend into the opposite semi-circular sleeve, making it easy to lock the two sets of semi-circular sleeves. This also drives the arc-shaped abutment plate on the inner wall to move radially closer to the clamp, thereby increasing the gripping force between the clamp and the pole, making the device firmly connected to the outside of the pole.

Detailed Implementation

[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 steel pipe tower support fixing device, such as Figures 1 to 7As shown, the device includes a clamp body 100, and a ring-shaped clamp formed by connecting a first semi-arc sleeve 110 and a second semi-arc sleeve 120 to the clamp body 100. A cross arm 130 is fixed to the curved outer wall of both the first semi-arc sleeve 110 and the second semi-arc sleeve 120. A bracket 131 for mounting electrical wires is fixed to the top of the cross arm 130. An arc cavity 190 is formed inside the first semi-arc sleeve 110 and the second semi-arc sleeve 120. An inner arc plate 180 is slidably disposed inside the arc cavity 190. Notches are formed at the upper and lower ends of the inner arc plate 180, near the end positions. 181, a gradually rising arc strip 183 is fixed inside the notch 181, a driven step block 182 is slidably provided on the inclined upper surface of the gradually rising arc strip 183, a roller 187 that slides in the notch 181 is fixed at the bottom of the driven step block 182, and a set of irregular grooves 184 are opened on the curved inner wall of the inner arc plate 180. Each set of irregular grooves 184 is equipped with a ball head rod 151 that extends to the outside of the first semi-arc sleeve 110. The end face of the ball head rod 151 is located outside the first semi-arc sleeve 110 and an arc-shaped abutment piece 150 that abuts against the rod is fixed.

[0025] The inclined surface of the gradually rising arc 183 is provided with a channel 185 for the roller 187 to slide, and the inner wall of the channel 185 is provided with a guide groove 186 for the roller 187 to roll at an incline. The top of the driven step block 182 is provided with a threaded hole 188 that matches the bolt 111.

[0026] The end faces of the first semi-circular sleeve 110 and the second semi-circular sleeve 120 are provided with relief grooves 160. The other end of the first semi-circular sleeve 110 and the second semi-circular sleeve 120 is a protrusion 170. The upper and lower ends of the clamp body 100 and the second semi-circular sleeve 120 are provided with bolts 111 that penetrate into the protrusion 170.

[0027] During installation, the first semi-circular sleeve 110 and the second semi-circular sleeve 120 are fitted onto the outer wall of the pole from two directions. At this time, the protrusion 170 will enter into the relief groove 160. The rotatable bolt 111 will then extend into the first semi-circular sleeve 110 and the second semi-circular sleeve 120. The bolt 111 will enter the protrusion 170 and mate with the threaded hole 188 at the top of the driven step block 182. This allows the first semi-circular sleeve 110 and the second semi-circular sleeve 120 to be initially fixed on the outer wall of the pole.

[0028] At this point, the external force of rotation is continued to be applied to the bolt 111. The driven step block 182 will rise along the outer wall of the bolt 111 until the bottom of the bolt 111 abuts against the bottom of the threaded hole 188. Its roller 187 will roll in the guide groove 186, generating a lateral force on the gradually rising arc strip 183 (causing the gradually rising arc strip 183 and the inner arc plate 180 to rotate in the arc cavity 190), causing one end of the inner arc plate 180 to extend into the arc cavity 190 opened in the second half arc sleeve 120 (while the inner arc plate 180 inside the second half arc sleeve 120 extends into the arc cavity 190 opened in the first half arc sleeve 110). The irregular groove 184 opened on the inner wall of the inner arc plate 180 generates a radially concentric force on the ball head rod 151, which will push the arc-shaped abutment 150 closer to the rod until it abuts, so that the first half arc sleeve 110 and the second half arc sleeve 120 are firmly fitted onto the outer wall of the rod.

[0029] Please refer to this carefully. Figure 2 and Figure 5 A storage groove 140 is provided at the position where the inner curved wall of the first semi-arc sleeve 110 contacts the arc-shaped abutment 150. A circular channel is provided in the storage groove 140 that is connected to the arc cavity 190 and allows the ball head rod 151 to slide.

[0030] The storage slot 140 allows the arc-shaped abutment 150 to be hidden within the curved inner wall of the first semi-arc sleeve 110 and the second semi-arc sleeve 120. When the first semi-arc sleeve 110 and the second semi-arc sleeve 120 are docked and fixed, the arc-shaped abutment 150 extends out of the outer wall of the rod to abut against it. The opening of the circular channel ensures that the ball head rod 151 pushes the arc-shaped abutment 150 in and out of the storage slot 140.

[0031] Please refer to this carefully. Figure 5 and Figure 6 Two sets of ball-head constraint rods are fixed to the curved outer wall of the ball-head rod 151, and shallow grooves constraining the irregular groove 184 are opened on the upper and lower inner walls of the irregular groove 184.

[0032] The groove and the ball head constraint rod have a mutual balancing effect, limiting the length that the ball head rod 151 can extend, thus preventing the storage groove 140 from being lost due to full extension.

[0033] In use, the first semi-circular sleeve 110 and the second semi-circular sleeve 120 are fitted onto the outer wall of the pole from two directions. At this time, the protrusion 170 will enter into the relief groove 160. The rotatable bolt 111 will then extend into the first semi-circular sleeve 110 and the second semi-circular sleeve 120. The bolt 111 will enter the protrusion 170 and mate with the threaded hole 188 at the top of the driven step block 182. This allows the first semi-circular sleeve 110 and the second semi-circular sleeve 120 to be initially fixed on the outer wall of the pole.

[0034] At this point, the external force of rotation is continued to be applied to the bolt 111. The driven step block 182 will rise along the outer wall of the bolt 111 until the bottom of the bolt 111 abuts against the bottom of the threaded hole 188. Its roller 187 will roll in the guide groove 186, generating a lateral force on the gradually rising arc strip 183 (causing the gradually rising arc strip 183 and the inner arc plate 180 to rotate in the arc cavity 190), causing one end of the inner arc plate 180 to extend into the arc cavity 190 opened in the second half arc sleeve 120 (while the inner arc plate 180 inside the second half arc sleeve 120 extends into the arc cavity 190 opened in the first half arc sleeve 110). The irregular groove 184 opened on the inner wall of the inner arc plate 180 generates a radially concentric force on the ball head rod 151, which will push the arc-shaped abutment 150 closer to the rod until it abuts, so that the first half arc sleeve 110 and the second half arc sleeve 120 are firmly fitted onto the outer wall of the rod.
