Abstract
Description
Technical Field
[0001] This invention relates to the field of lifting fixture technology, and specifically to a side-door type drone lifting fixture. Background Technology
[0002] A surge arrester (line surge arrester) is a protective device installed on a transmission tower to protect against lightning or switching overvoltages. Generally, one end of the surge arrester needs to be installed on the metal angle steel of the tower, and the other end needs to be installed on the conductor to achieve the function of lightning protection.
[0003] Many companies now use drones to drive clamps to secure angle steel on power towers, thereby fixing surge arresters. However, the common clamping method involves the upper and lower clamps clamping the angle steel horizontally from both sides. But if the upper and lower clamps are subjected to a horizontal force, and if the force is too large, exceeding the friction between the clamps and the horizontal surface of the angle steel, the clamps will shift. Over time, the angle steel may come off the clamps or the clamps may loosen, affecting the clamping effect.
[0004] Therefore, we need a lifting clamp to solve the above technical problems. Summary of the Invention
[0005] The purpose of this invention is to provide a side-mounted door-type drone hoisting fixture, which solves the technical problem in the prior art where the fixture is easily deflected when subjected to horizontal reverse displacement by using angle steel for progressive fixation in the upper and lower directions.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following solution: A side-mounted door-type drone hoisting fixture includes a mounting frame and an upper clamp or a lower clamp slidably mounted on the mounting frame. The upper clamp or the lower clamp slides closer to or further away from each other. The upper clamp or the lower clamp slides closer to each other to clamp an angle steel. The side of the upper clamp and the lower clamp that enters the angle steel respectively has a plug-in groove and a plug-in part for mutual connection. The upper clamp or the lower clamp slides to drive the plug-in part to extend into the plug-in groove.
[0007] As a further technical solution, the insertion slot is located on the upper clamp, the insertion part is located on the lower clamp, and the side wall of the insertion slot also has an arc-shaped opening. The arc-shaped opening gradually increases in length from the inside to the outside of the insertion slot, and the outer wall of the insertion part has an arc-shaped part corresponding to the arc-shaped opening.
[0008] As a further technical solution, the upper clamp and the lower clamp both have clamping surfaces on their adjacent surfaces. The clamping surfaces are used to clamp the horizontal surface of the angle steel. The upper clamp and the lower clamp also have mounting grooves. The mounting grooves are located on the upper clamp or the lower clamp and are perpendicular to the clamping surfaces.
[0009] As a further technical solution, there are at least four mounting slots, which are evenly distributed on the upper clamp and the lower clamp. The mounting slots are symmetrically located on both sides of the clamping surface, and the mounting slots are used to store the vertical surface of the angle steel.
[0010] As a further technical solution, the connection between the mounting groove and the clamping surface has a correction groove, and the cross-sectional width of the correction groove gradually increases in the direction away from the mounting groove.
[0011] As a further technical solution, the inner wall of the correction groove is arc-shaped.
[0012] As a further technical solution, the upper clamp has a guide portion arranged vertically; it also includes guide plates, there are two guide plates, the two guide plates are respectively arranged on both sides of the lower clamp, the two guide plates form a guide groove, the guide portion passes through the guide groove, the lower clamp is slidably arranged on the guide portion through the guide groove, and the lower clamp slides closer to or further away from the upper clamp.
[0013] As a further technical solution, a lifting ring is also included, which is disposed on the mounting frame, and the drone lifts the mounting frame through the lifting ring.
[0014] As a further technical solution, an elastic pad is also included, which is disposed on the clamping surface of the upper clamp or the lower clamp.
[0015] As a further technical solution, it also includes a drive screw, a screw sleeve, and a drive motor. The drive screw is disposed on the lower clamp, the drive motor is disposed on the guide portion of the upper clamp, the screw sleeve is disposed on the upper clamp, the drive screw passes through the screw sleeve, the screw sleeve is threadedly engaged with the drive screw, the output end of the drive motor is connected to the screw sleeve, and the rotation of the screw sleeve is used to drive the lower clamp to move along the guide portion.
[0016] The beneficial effects of this invention are as follows: In this invention, the upper or lower clamp slides closer to each other on the linear guide rail of the mounting frame. The insertion part of the lower clamp aligns with and extends into the insertion slot of the upper clamp. The cooperation between the insertion part and the insertion slot allows one side of the upper and lower clamps to be connected. When subjected to a horizontal force, the insertion part and the insertion slot will interact with each other, preventing the upper and lower clamps from becoming misaligned in the horizontal direction, thus affecting the clamping effect. Without the cooperation between the insertion part and the insertion slot, when the upper and lower clamps are subjected to a horizontal force, they may become misaligned in the horizontal direction, thus affecting the clamping effect on the angle steel.
[0017] The design of the slot and the connector allows the clamp to not only rely on the clamping force in the vertical direction when clamping the angle steel, but also enhance the ability to resist the horizontal force through the side connector, effectively preventing the angle steel from shifting within the clamp and improving the clamping effect.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0023] like Figures 1-3 As shown, a side-mounted door-type UAV hoisting fixture includes a mounting frame 1 and an upper clamp 2 and a lower clamp 3 slidably mounted on the mounting frame 1. The upper clamp 2 and the lower clamp 3 slide closer to each other or further apart. The upper clamp 2 and the lower clamp 3 slide closer to each other to clamp an angle steel. The side of the upper clamp 2 and the lower clamp 3 that is used to enter the angle steel respectively has a plug groove 201 and a plug part 301 for mutual connection. The upper clamp 2 or the lower clamp 3 slides to drive the plug part 301 to extend into the plug groove 201.
[0024] In this embodiment, the upper clamp 2 and the lower clamp 3 slide close together on the linear guide rail of the mounting frame 1. The insertion part 301 of the lower clamp 3 is aligned and extends into the insertion groove 201 of the upper clamp 2. The cooperation of the insertion part 301 and the insertion groove 201 allows one side of the upper clamp 2 and the lower clamp 3 to be connected. When subjected to a horizontal force, the insertion part 301 and the insertion groove 201 will interact with each other, preventing the upper clamp 2 and the lower clamp 3 from being misaligned in the horizontal direction, thus affecting the clamping effect. Without the cooperation of the insertion part 301 and the insertion groove 201, when the upper clamp 2 and the lower clamp 3 are subjected to a horizontal force, the upper clamp 2 and the lower clamp 3 may be misaligned in the horizontal direction, thus affecting the clamping effect on the angle steel.
[0025] The design of the insertion slot 201 and the insertion part 301 enables the clamp to not only rely on the clamping force in the vertical direction when clamping the angle steel, but also enhance the ability to resist the horizontal force through the side insertion connection, effectively preventing the angle steel from shifting in the clamp and improving the clamping effect.
[0026] Furthermore, the insertion groove 201 is located on the upper clamp 2, the insertion part 301 is located on the lower clamp 3, and the side wall of the insertion groove 201 also has an arc-shaped opening 211. The arc-shaped opening 211 gradually increases in length from the inside to the outside of the insertion groove 201, and the outer wall of the insertion part 301 has an arc-shaped part corresponding to the arc-shaped opening 211.
[0027] In this embodiment, when the plug part 301 is inserted into the plug slot 201, the arc-shaped part is inserted along the guide of the arc-shaped opening 211. The design of the arc-shaped opening 211 and the arc-shaped part significantly improves the fault tolerance of the plug and reduces the difficulty of docking the slot.
[0028] Furthermore, the upper clamp 2 and the lower clamp 3 each have a clamping surface 4 on their adjacent surfaces. The clamping surface 4 is used to clamp the horizontal surface of the angle steel. The upper clamp 2 and the lower clamp 3 also have a mounting groove 302. The mounting groove 302 is located on the upper clamp 2 or the lower clamp 3 and is perpendicular to the clamping surface 4.
[0029] In this embodiment, the clamping surface 4 clamps the horizontal surface of the angle steel under the force of the lower clamp. The friction of the clamping surface 4 and the force of the mounting groove 302 limit the horizontal displacement of the angle steel. The mounting groove 302 accommodates the vertical surface of the angle steel. The design of the clamping surface 4 and the mounting groove 302 fixes the angle steel from multiple dimensions, enhancing the clamping effect of the clamps. The two clamping surfaces 4 of the upper clamp 2 and the lower clamp 3 clamp the horizontal surface of the angle steel from the upper and lower sides, while the vertical surface of the angle steel is inserted into the mounting groove 302. Regardless of whether the angle steel is subjected to horizontal or vertical forces, the clamping surface 4 and the mounting groove 302 can fix the angle steel.
[0030] Furthermore, there are at least four mounting slots 302, which are evenly distributed on the upper clamp 2 and the lower clamp 3. The mounting slots 302 are symmetrically located on both sides of the clamping surface 4, and the mounting slots 302 are used to store the vertical surface of the angle steel.
[0031] In this embodiment, the mounting slots 302 are symmetrically distributed on both sides of the clamping surface 4 to accommodate the vertical surface of the angle steel. The uniform and symmetrical distribution of the four mounting slots 302 improves the adaptability of the clamp to angle steel with different placement methods. Regardless of which side the vertical surface and horizontal surface of the angle steel are on, as long as the vertical surface of the angle steel is inserted into one of the mounting slots 302, the clamping surface 4 will still clamp the horizontal surface of the angle steel from the top and bottom sides, and complete clamping can be performed. If multiple mounting slots 302 are provided, it can adapt to the clamping of angle steel of different lengths.
[0032] Furthermore, the connection between the mounting groove 302 and the clamping surface 4 has a correction groove 401, and the cross-sectional width of the correction groove 401 gradually increases in the direction away from the mounting groove 302.
[0033] In this embodiment, as Figures 4-7 As shown, before the angle steel enters the mounting groove 302, if the angle steel is tilted to a certain extent, the vertical surface of the angle steel will contact the correction groove 401. When the lower clamp 3 or the upper clamp 2 moves vertically, the angle steel acts on the correction groove 401 and the mounting groove 302, causing the upper clamp 2 and the lower clamp 3 to drive the mounting frame 1 to deflect to a certain extent, so that the vertical surface of the angle steel can enter the mounting groove 302. Finally, the upper clamp 2 and the lower clamp 3 can be adaptively deflected according to the deflection angle of the angle steel, so that the clamping surfaces 4 of the upper clamp 2 and the lower clamp 3 can clamp the angle steel directly against the horizontal surface.
[0034] Furthermore, the inner wall of the correction groove 401 is arc-shaped.
[0035] In this embodiment, the arc-shaped inner wall makes the interaction between the angle steel and the straightening groove 401 smoother. The upper clamp 2 and the lower clamp 3 adapt to the deflection of the angle steel more smoothly. The upper clamp 2 and the lower clamp 3 will deflect slowly, so that the vertical surface of the angle steel enters the mounting groove 302, and the clamping surface 4 can clamp the horizontal surface of the angle steel more closely.
[0036] Furthermore, the upper clamp 2 has a guide portion 202 arranged vertically; it also includes guide pieces 5, of which there are two, and the two guide pieces 5 are respectively arranged on both sides of the lower clamp 3. The two guide pieces 5 form a guide groove 501, through which the guide portion 202 passes. The lower clamp 3 is slidably disposed on the guide portion 202 through the guide groove 501, and the lower clamp 3 slides closer to or further away from the upper clamp 2.
[0037] In this embodiment, the lower clamp 3 slides on the guide portion 202 via the guide groove 501 formed by the guide plates 5, moving closer to or further away from the upper clamp 2. The guide portion 202 and the guide plates 5 provide stable guidance for the lower clamp 3, ensuring the accuracy of clamping.
[0038] Furthermore, it also includes a lifting ring 6, which is disposed on the mounting frame 1, and the drone lifts the mounting frame 1 through the lifting ring 6.
[0039] In this embodiment, the drone is connected to the mounting frame 1 via a hook and a lifting ring 6. The lifting ring 6 facilitates the connection and separation of the drone from the clamp, thus improving work efficiency.
[0040] Furthermore, it also includes an elastic pad 7, which is disposed on the clamping surface 4 of the upper clamp 2 or the lower clamp 3.
[0041] In this embodiment, the elastic pad 7 adheres to the surface of the angle steel, increasing friction, preventing scratches on the angle steel, and also releasing elasticity to eliminate gaps in the mechanical parts. The elastic pad 7 improves the friction between the clamp and the angle steel, protects the surface of the angle steel, and enhances the stability of the clamping.
[0042] Furthermore, it also includes a drive screw 8, a screw sleeve 9, and a drive motor 10. The drive screw 8 is disposed on the lower clamp 3, the drive motor 10 is disposed on the guide portion 202 of the upper clamp 2, the screw sleeve 9 is disposed on the upper clamp 2, the drive screw 8 passes through the screw sleeve 9, the screw sleeve 9 is threadedly engaged with the drive screw 8, the output end of the drive motor 10 is connected to the screw sleeve 9, and the rotation of the screw sleeve 9 is used to drive the lower clamp 3 to move along the guide portion 202.
[0043] In this embodiment, after the drive motor 10 is powered on, its output shaft drives the screw sleeve 9 to rotate. Under the action of the thread of the screw sleeve 9, the drive screw 8 moves linearly along the guide portion 202, thereby causing the lower clamp 3 and the upper clamp 2 to move closer or further apart. The drive mechanism composed of the drive screw 8, the screw sleeve 9, and the drive motor 10 realizes the automation and precise control of the clamping action.
[0044] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Based on the technical essence of the present invention, any simple modifications, equivalent substitutions, and improvements made to the above embodiments within the spirit and principles of the present invention shall still fall within the protection scope of the present invention.
