Description

Technical Field

[0001] This utility model relates to the field of steel structure processing technology, specifically a clamp for processing power transmission towers. Background Technology

[0002] A power transmission tower is a supporting frame structure that elevates power lines, cables, or signal transmitting / receiving devices. It is commonly made of steel. The steel frame is mainly assembled by welding and bolting angle steel. Therefore, it is necessary to pre-drill holes in the angle steel.

[0003] A search of the China Patent Network reveals a clamp for processing power transmission towers, disclosed in patent announcement (CN222094754U). This clamp can automatically hold and fix angle steel with an electric push rod, eliminating the need for manual operation. At the same time, the drive wheel can easily move the angle steel to switch the drilling position, making the drilling operation flexible and efficient.

[0004] However, the above technical solution has certain drawbacks. Since the angle steel itself has a certain length, when it is necessary to change the position of the angle steel at the drilling location, its electric push rod no longer serves to clamp the angle steel. The angle steel will tilt upwards due to its own weight. At this time, it is necessary to manually apply downward pressure to the angle steel to drive it into the clamping gap, which indirectly reduces the drilling efficiency of the angle steel. At the same time, the metal chips produced by drilling will also enter the clamping gap from the processing groove due to the movement of the angle steel, which will hinder the movement of the angle steel and even make it impossible to place the angle steel horizontally in the clamping gap. Therefore, a clamp for processing power transmission towers is proposed. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a clamp for processing power transmission towers, so as to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a clamp for processing power transmission towers, comprising a clamp base, a slot horizontally formed on the upper surface of the clamp base at a central position, a drilling groove communicating with the slot on the front surface of the clamp base, a storage groove horizontally formed on the bottom of the clamp base, two sets of extension plates slidably disposed in the storage groove, a support strip fixed at the edge of the top of the extension plates near the end face, a receiving groove extending into the clamp base formed on the lower inner wall of the drilling groove, a movable plate for sealing the drilling groove slidably disposed in the receiving groove, the movable plate being centrally convex, and two sets of telescopic rods fixed to the lower inner wall of the receiving groove provided at the bottom of the movable plate.

[0007] As a preferred technical solution, the receiving groove extends to the front surface of the clamp seat, and the front surface of the clamp seat is located within the receiving groove and has a seal adsorbed thereon.

[0008] As a preferred technical solution, the upper and lower surfaces of the seal are magnetically attached and fixed in the receiving groove.

[0009] As a preferred technical solution, the front and rear surfaces of the extension plate are slidably connected to the storage groove using dovetail blocks. The inner wall of the storage groove is provided with dovetail grooves at positions corresponding to the dovetail blocks. The upper inner wall of the storage groove is provided with matching strip grooves at positions corresponding to the support strips. The upper inner wall of the strip grooves and the lower inner wall of the card slots are on the same horizontal plane.

[0010] As a preferred technical solution, the rear surface of the fixture seat is provided with a relief groove that communicates with the slot, and a roller is rotatably mounted inside the relief groove, the curved outer wall of the roller being tangent to the slot.

[0011] As a preferred technical solution, a pad is fixed on the lower surface of the clamp seat, and two sets of anti-slip textures are symmetrically arranged on the lower surface of the pad.

[0012] As a preferred technical solution, the front surface of the fixture seat is provided with positioning holes that communicate with the slot on both sides of the drilling groove. Each set of positioning holes is equipped with an electric push rod, and the telescopic end of the electric push rod is fixedly contacting the positioning plate of the angle steel in the slot.

[0013] As a preferred technical solution, the upper surface of the fixture base is engraved with scale lines on both sides of the drill groove.

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

[0015] This utility model uses an extension plate and a support strip to support both ends of the angle steel, preventing the angle steel from tilting up during drilling. At the same time, it refers to the scale lines to determine the distance the angle steel moves, ensuring the accuracy of the drilling position. It also collects and stores the debris generated during drilling, preventing it from entering the slot as the angle steel moves, thus preventing the angle steel from being obstructed and affecting the drilling process.

[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 clamp for processing power transmission towers, such as Figures 1 to 4 As shown, the fixture includes a fixture base 100. A slot 150 is horizontally formed on the upper surface of the fixture base 100 at the center position. A drilling slot 140 is formed on the front surface of the fixture base 100, which communicates with the slot 150. A storage slot 160 is horizontally formed on the bottom of the fixture base 100. Two sets of extension plates 170 are slidably arranged in the storage slot 160. A support strip 171 is fixed at the top edge of the extension plate 170 near the end face. A receiving slot 103 extending into the fixture base 100 is formed on the lower inner wall of the drilling slot 140. A movable plate 111 that blocks the drilling slot 140 is slidably arranged in the receiving slot 103. The movable plate 111 is convex in the middle. Two sets of telescopic rods 112 fixed to the lower inner wall of the receiving slot 103 are provided at the bottom of the movable plate 111.

[0025] The front surface of the clamp base 100 is provided with positioning holes 102 on both sides of the drilling groove 140, which are connected to the slot 150. Each set of positioning holes 102 is equipped with an electric push rod 120, and the telescopic end of the electric push rod 120 is fixedly abutting against the positioning plate 121 of the angle steel in the slot 150.

[0026] The rear surface of the fixture base 100 is provided with a relief groove 101 that communicates with the slot 150. A roller 180 is rotatably mounted inside the relief groove 101, and the curved outer wall of the roller 180 is tangent to the slot 150.

[0027] Place the angle steel in the slot 150 and extend the telescopic end of the electric push rod 120 to drive the positioning plate 121 into the slot 150 to contact the angle steel. This will fix the angle steel in the slot 150, allowing drilling to be performed on the upper surface of the angle steel at the position of the drilling slot 140. After the drilling is completed, control the electric push rod 120 to reset, so that the positioning plate 121 no longer clamps the angle steel. This allows the angle steel to be moved within the slot 150, thereby changing the drilling position.

[0028] When drilling angle steel, two sets of extension plates 170 can be manually pulled out from the storage slot 160, so that the support strip 171 can support the end of the angle steel, which can prevent the angle steel from tilting. When the angle steel moves, the extension plates 170 can be pushed to move together, which can support the end of the angle steel at all times. The roller 180 can assist the movement of the angle steel, making the drilling of angle steel more flexible.

[0029] The debris generated during drilling falls to the top of the movable plate 111 and slides along the inclined surface of the top of the movable plate 111 to both sides, where it is temporarily stored on the top of the movable plate 111. This prevents the angle steel from moving and entering the slot 150. When a certain amount of debris accumulates on the top of the movable plate 111, a vertical downward force can be applied to the movable plate 111 to lower the movable plate 111 and compress the telescopic rod 112, causing a gap to be created between the top of the movable plate 111 and the drilling slot 140. This allows the debris to slide into the receiving slot 103 from the gap. Subsequently, the metal debris inside the receiving slot 103 can be cleaned by manually removing the seal 110.

[0030] Please refer to this carefully. Figure 1 and Figure 4 The receiving groove 103 extends to the front surface of the clamp seat 100, and the front surface of the clamp seat 100 is located in the receiving groove 103 where the seal 110 is adsorbed.

[0031] The upper and lower surfaces of the seal 110 are magnetically attached and fixed in the receiving groove 103.

[0032] The seal 110 can be manually removed from the receiving groove 103, exposing the receiving groove 103 to the outside. The clamp seat 100 can be tilted forward to allow the metal debris inside the receiving groove 103 to be discharged to the outside.

[0033] Please refer to this carefully. Figure 1 and Figure 2 The front and rear surfaces of the extension plate 170 are slidably connected to the storage groove 160 by dovetail blocks. The inner wall of the storage groove 160 is provided with dovetail grooves at the corresponding positions of the dovetail blocks. The upper inner wall of the storage groove 160 is provided with matching strip grooves 161 at the corresponding positions of the support strip 171. The upper inner wall of the strip groove 161 and the lower inner wall of the card slot 150 are on the same horizontal plane.

[0034] The dovetail groove and dovetail block increase the friction between the extension plate 170 and the storage groove 160, ensuring the stability of the extension plate 170 extending to the specified size. At the same time, the top of the support strip 171 can ensure that the angle steel and the slot 150 are kept horizontal, which can better facilitate the drilling of the angle steel.

[0035] Please refer to this carefully. Figure 1 and Figure 2A pad 190 is fixed on the lower surface of the clamp seat 100, and two sets of anti-slip textures 191 are symmetrically arranged on the lower surface of the pad 190.

[0036] The anti-slip texture increases the coefficient of friction at the bottom of the pad 190, making the fixture seat 100 more stable when placed.

[0037] Please refer to this carefully. Figure 1 and Figure 2 The upper surface of the fixture base 100 is engraved with scale lines 130 on both sides of the drilled groove 140.

[0038] The size of the angle steel movement can be determined by referring to the scale line 130, which makes the data for drilling the angle steel seat more accurate.

[0039] In use, place the angle steel in the slot 150 and extend the telescopic end of the electric push rod 120 to drive the positioning plate 121 into the slot 150 to contact the angle steel. This fixes the angle steel in the slot 150, allowing drilling to be performed on the upper surface of the angle steel at the position of the drilling slot 140. After drilling is completed, control the electric push rod 120 to reset, causing the positioning plate 121 to stop clamping the angle steel. This allows the angle steel to be moved within the slot 150, thereby changing the drilling position.

[0040] When drilling angle steel, two sets of extension plates 170 can be manually pulled out from the storage slot 160, so that the support strip 171 can support the end of the angle steel, which can prevent the angle steel from tilting. When the angle steel moves, the extension plates 170 can be pushed to move together, which can support the end of the angle steel at all times. The roller 180 can assist the movement of the angle steel, making the drilling of angle steel more flexible.

[0041] The debris generated during drilling falls to the top of the movable plate 111 and slides along the inclined surface of the top of the movable plate 111 to both sides, where it is temporarily stored on the top of the movable plate 111. This prevents the angle steel from moving and entering the slot 150. When a certain amount of debris accumulates on the top of the movable plate 111, a vertical downward force can be applied to the movable plate 111 to lower the movable plate 111 and compress the telescopic rod 112, causing a gap to be created between the top of the movable plate 111 and the drilling slot 140. This allows the debris to slide into the receiving slot 103 from the gap. Subsequently, the metal debris inside the receiving slot 103 can be cleaned by manually removing the seal 110.
