Description

Technical Field

[0001] The utility model relates to the technical field of electric iron towers, in particular to a processing and positioning device for a steel pipe of an electric iron tower. Background Art

[0002] The power tower is a facility used to support overhead lines when transmitting electricity through high-voltage overhead lines. It is an important component of the power system and is used to support and fix power lines to ensure the stable operation of the power system. It can withstand the weight and tension of the transmission lines and distribute them to the foundation and the ground to ensure the safe and stable operation of the transmission lines. The power tower steel pipe is one of the main components of the power tower and is used to form the main structure of the tower. In the production process of the power tower steel pipe, a power tower steel pipe processing and positioning device is required to position and process it. Among them, the "seamless steel pipe processing and positioning device" disclosed in the application number "CN220218132U" The problem that the seamless steel pipe cannot rotate when being compressed has been solved, so that when the back of the seamless steel pipe needs to be processed, the steel pipe needs to be turned over and compressed again, which affects the processing efficiency. However, in actual use, there are still many defects in the processing and positioning device of the power tower steel pipe with similar structure, such as: it is impossible to automatically clamp and position the pipeline by its own weight, and the staff needs to manually operate the clamping mechanism to clamp and position the pipeline or the electrical equipment drive device needs to clamp and position it. The manual clamping and positioning efficiency is low, and the electrical equipment drive increases the steel pipe processing cost. At the same time, an unlocking operation is required, which reduces the steel pipe processing efficiency. Therefore, it is necessary to design a processing and positioning device for the power tower steel pipe. Utility Model Content

The downward conical telescopic rod squeezes the guide wheel at the bottom of the clamping rod through the inclined surfaces on both sides, so that the clamping rod flips to clamp and position both sides of the pipe to prevent movement or shaking during processing, and realizes the function of automatic clamping and positioning using the dead weight of the pipe, which improves the efficiency of pipe clamping and positioning. At the same time, the clamping rod adopts a flippable design to adapt to steel pipes of different diameters; when removing the steel pipe, the pressure on the conical telescopic rod that lifts the steel pipe disappears, and the guide wheel at the bottom of the clamping rod is not locked by the inclined surfaces on both sides of the conical telescopic rod, so that the clamping rod expands outward under the action of lifting the steel pipe, realizing quick unlocking of the clamping of the steel pipe, facilitating quick removal of the steel pipe for processing, and improving the efficiency of steel pipe processing.

[0012] 2. The shaft is driven to rotate by rotating the turntable, and the rotating shaft drives the turbine to rotate. The rotating turbine drives the first lifting mechanism to rotate through the connecting plate.

DETAILED DESCRIPTION

[0019] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] Embodiment 1

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the utility model proposes a power tower steel pipe processing and positioning device, including an operating table 1, a first lifting mechanism 3, a clamping and positioning mechanism 4 and a second lifting mechanism 5, one side of the first lifting mechanism 3 and the second lifting mechanism 5 are both installed with a clamping and positioning mechanism 4 through a slide groove, and the clamping and positioning mechanism 4 includes a mounting seat 401, a conical telescopic rod 402, a motor 403, a driving wheel 404, a clamping rod 405, and a guide wheel 406, the interior of the mounting seat 401 is installed with a conical telescopic rod 402 through a slide rail, a motor 403 is fixedly installed on one side of the top of the conical telescopic rod 402, and a driving wheel 404 is fixedly installed on the output end of the motor 403, two sets of opposite clamping rods 405 are installed inside the mounting seat 401 through a rotating shaft, and guide wheels 406 are installed at both ends of the clamping rod 405 through shaft bolts;

[0022] An angle adjustment mechanism 2 is rotatably installed inside the operating table 1, and the angle adjustment mechanism 2 includes a shaft 201, a worm 202, a turbine 203, and a connecting plate 204. The worm 202 is fixedly installed on one end of the shaft 201, the turbine 203 is embedded on one side of the worm 202, and the connecting plate 204 is fixedly installed on one side of the turbine 203.

[0023] It should be noted that: the inclined surfaces on both sides of the conical telescopic rod 402 are respectively connected with the guide wheels 406 at the bottom of the clamping rod 405. When the conical telescopic rod 402 is subjected to pressure, it automatically moves downward. The downwardly moved conical telescopic rod 402 squeezes the guide wheels 406 at the bottom of the clamping rod 405 through the inclined surfaces on both sides, so that the clamping rod 405 is turned over to clamp and position the two sides of the pipe. The guide wheels 406 are made of rubber material to ensure that the steel pipe will not slip during the processing. The motor 403 is powered on to drive the driving wheel 404 to rotate. The rotating driving wheel 404 can drive the steel pipe to rotate and automatically adjust the processing surface of the steel pipe.

[0024] The turbine 203 is installed inside the operating table 1 through a rotating shaft. The turbine 203 adopts a semi-tooth structure to limit the rotation angle of the turbine 203, thereby limiting the rotation adjustment angle of the first lifting mechanism 3. A pointer is fixedly installed on one side of the first lifting mechanism 3 to facilitate the staff to observe the precise position of the angle adjustment of the first lifting mechanism 3.

[0025] Furthermore, a top plate 101 is installed on the top of the operating table 1, a measuring ruler 102 is pasted on the top of the top plate 101, a linear slide groove 103 is opened inside the top plate 101, and a first lifting mechanism 3 is installed on the top of the top plate 101 through an arc-shaped slide groove.

[0026] It should be noted that an arc-shaped slide groove is provided on one side of the top of the top plate 101, and the arc-shaped slide groove facilitates the first lifting mechanism 3 to rotate and adjust the clamping angle of the steel pipe. The measuring ruler 102 consists of an arc-shaped ruler and a straight ruler. The arc-shaped ruler is convenient for measuring the adjustment angle of the first lifting mechanism 3, and the straight ruler is convenient for measuring the horizontal movement distance of the second lifting mechanism 5, so as to accurately control the processing length of the steel pipe. The straight slide groove 103 can limit the moving direction of the second lifting mechanism 5, thereby ensuring the stability of the movement of the second lifting mechanism 5.

[0027] Furthermore, a turntable is fixedly mounted on one end of the shaft rod 201 , and one side of the top of the connecting plate 204 is fixedly connected to the bottom of the first lifting mechanism 3 via a connecting column.

[0028] It should be noted that the rotating turntable drives the shaft 201 to rotate through the shaft 201, the rotating shaft 201 drives the turbine 203 to rotate, and the rotating turbine 203 drives the first lifting mechanism 3 to move along the arc-shaped slide groove through the connecting plate 204 to achieve angle adjustment of the first lifting mechanism 3.

[0029] Furthermore, the first lifting mechanism 3 includes an installation box 301, a threaded rod 302, a linkage pulley group 303, a threaded sleeve 304, and a transmission bevel gear 305, and two groups of threaded rods 302 are rotatably installed on the top inside the installation box 301, the outer sides of the two groups of threaded rods 302 are connected with threaded sleeves 304 through threaded sleeves, the bottom ends of the two groups of threaded rods 302 are fixedly installed with a linkage pulley group 303, one side of the bottom of the linkage pulley group 303 is fixedly installed with a transmission bevel gear 305, and one side of the transmission bevel gear 305 is meshed with an adjustment bevel gear.

[0030] It should be noted that: a mounting box 301 extends from one side of the threaded sleeve 304 and is fixedly connected to the clamping and positioning mechanism 4. A turning handle is installed on the front of the adjusting bevel gear through a connecting rod. The turning handle drives the adjusting bevel gear to rotate through the connecting rod. The rotating adjusting bevel gear drives the meshing transmission bevel gear 305 to rotate. The rotating transmission bevel gear 305 drives the two groups of threaded rods 302 to rotate synchronously through the interlocking pulley group 303. The synchronously rotating threaded rods 302 drive the threaded sleeve 304 to move vertically through the threads. The vertically moving threaded sleeve 304 drives the fixedly connected clamping and positioning mechanism 4 to be raised and lowered to meet the height processing requirements of different steel pipes.

[0031] Furthermore, a second lifting mechanism 5 is installed on the top of the top plate 101 through a linear slide groove 103, and an adjusting screw rod 501 is rotatably installed inside the operating table 1. An adjusting thread sleeve 502 is threadedly sleeved on the outer side of the adjusting screw rod 501, and the top of the adjusting thread sleeve 502 passes through the linear slide groove 103 and is fixedly connected to the bottom of the second lifting mechanism 5.

[0032] It should be noted that one end of the adjusting screw rod 501 extends to the outside of the operating table 1 and is fixedly installed with a crank. Turning the crank drives the adjusting screw rod 501 to rotate. The rotating adjusting screw rod 501 drives the second lifting mechanism 5 to move through the adjusting thread sleeve 502, thereby adjusting the horizontal position of the second lifting mechanism 5, which is convenient for adjustment according to the processing needs of the steel pipe length.

[0033] Working principle: The horizontal position of the second lifting mechanism 5 is adjusted according to the processing requirements of the steel pipe length, and the crank is turned to drive the adjusting screw rod 501 to rotate. The rotating adjusting screw rod 501 drives the second lifting mechanism 5 to move through the adjusting screw sleeve 502. The moving second lifting mechanism 5 drives the clamping and positioning mechanism 4 at the top to adjust the distance of the clamped steel pipe.

[0034] Then, the angle of the first lifting mechanism 3 is adjusted according to the processing angle of the steel pipe. The rotating turntable drives the shaft 201 to rotate through the shaft 201. The rotating shaft 201 drives the turbine 203 to rotate. The rotating turbine 203 drives the first lifting mechanism 3 to rotate through the connecting plate 204. The rotating first lifting mechanism 3 cooperates with the measuring ruler 102 to accurately adjust the angle of the first lifting mechanism 3. By adjusting the angle of the first lifting mechanism 3, the angle of the steel pipe clamped by the clamping and positioning mechanism 4 can be adjusted.

[0035] The height of the steel pipe is adjusted by the first lifting mechanism 3. The adjusting bevel gear is driven to rotate through the connecting rod by turning the turning handle. The rotating adjusting bevel gear drives the meshing transmission bevel gear 305 to rotate. The rotating transmission bevel gear 305 drives the two sets of threaded rods 302 to rotate synchronously through the linkage pulley group 303. The synchronously rotating threaded rods 302 drive the threaded sleeve 304 to move vertically through the threads. The vertically moving threaded sleeve 304 drives the fixedly connected clamping and positioning mechanism 4 to perform lifting and lowering adjustment to meet the height processing requirements of different steel pipes.

[0036] The steel pipe to be processed is placed on the top of the clamping and positioning mechanism 4. First, the steel pipe squeezes the top guide wheel 406 of the clamping rod 405, so that the clamping rod 405 expands outward. After the steel pipe enters between the two groups of clamping rods 405, the steel pipe's own weight is used to press the driving wheel 404 to drive the conical telescopic rod 402 to automatically move downward. The downward-moving conical telescopic rod 402 squeezes the bottom guide wheel 406 of the clamping rod 405 through the inclined surfaces on both sides, so that the clamping rod 405 is turned inward to clamp and position both sides of the pipeline. The motor 403 is powered on to drive the driving wheel 404 to rotate. The rotating driving wheel 404 can drive the steel pipe to rotate and automatically adjust the processing surface of the steel pipe.

[0037] When removing the steel pipe, the pressure on the tapered telescopic rod 402 that lifts the steel pipe disappears, and the guide wheel 406 at the bottom of the clamping rod 405 is not locked by the inclined surfaces on both sides of the tapered telescopic rod 402, so that the clamping rod 405 expands outward under the action of lifting the steel pipe, thereby quickly unlocking the clamping of the steel pipe and facilitating and quickly taking out the steel pipe.

Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
