Description

Technical Field

[0001] This utility model relates to the field of steel pipe straightening technology, specifically to a loading mechanism for a steel pipe straightening machine. Background Technology

[0002] A steel pipe straightening machine, also known as a steel pipe adjusting machine, is a maintenance machine specifically used to straighten and repair scaffolding steel pipes and other pipes that have been bent and deformed during construction. Its main functions include straightening, rust removal, and painting. It can solve problems such as bending, rusting, and corrosion of steel pipes caused by long-term use, ensuring the safety and durability of steel pipes during use.

[0003] A loading mechanism for a steel pipe straightening machine, disclosed in CN219881061U, features a liftable crossbeam at the frame. A clamping head is located on the crossbeam, and two clamping components are positioned opposite each other at the support legs. Each clamping component has a clamping end that can move horizontally to change the distance between adjacent clamping components. In this configuration, with the steel pipe horizontally supported, the loading mechanism can load the pipe from its top and side walls, achieving straightening through the compression of the clamping head and clamping components. However, this design uses a circular clamping head and clamping end. The applicability of a circular clamping head may be limited because the cross-sectional shape of non-circular steel pipes does not match the circular clamping head, potentially leading to uneven clamping and affecting the straightening effect.

[0004] To address this, a loading mechanism for a steel pipe straightening machine is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that circular clamping heads are not suitable for steel pipes of different shapes. This utility model provides a loading mechanism for a steel pipe straightening machine.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A loading mechanism for a steel pipe straightening machine includes a base, a slide table on the top of the base, fixed seats arranged at equal intervals inside the slide table, a placement plate fixedly connected to the top of each fixed seat, slide grooves on the left and right sides of the base, frames movably connected inside the slide grooves, a moving mechanism inside the slide grooves, a top plate fixedly connected between the frames, rectangular holes on the walls of the frames, screw drive mechanisms inside the rectangular holes, a movable block movably connected to the output end of the screw drive mechanism, the movable block extending towards a longitudinal circular tube, through holes on the upper and lower sides of both ends of the circular tube, a fixed plate at the bottom of the hydraulic rod, an arc-shaped clamping head or a square clamping head fixedly connected to the top of the fixed plate, a fixed component on the top of the base, and a moving component on the top of the base.

[0008] Furthermore, the fixing component includes a rectangular block at one end of the circular tube that is far apart from each other, a placement groove on the side of the rectangular block near the circular tube, three equidistant limiting holes inside the rectangular block, movable rods movably connected inside each of the far apart limiting holes, horizontal plates fixedly connected at the upper and lower ends of the movable rods, an insert rod fixedly connected to the top of the lower horizontal plate, and compression springs provided on the upper end of the outer wall surface of each movable rod.

[0009] Furthermore, the shape and volume of the insertion rod are adapted to the interior of the through hole.

[0010] Furthermore, the moving component includes support legs fixedly connected to the left and right sides of the rectangular block, a rectangular groove is provided on the top of the fixed plate, a stepper motor is fixedly connected to the front side of the fixed plate, a rotating shaft is fixedly connected to the output end of the stepper motor, and threaded grooves with opposite directions are provided at the front and rear ends of the outer wall of the rotating shaft, and a sliding rod is fixedly connected inside the fixed plate.

[0011] Furthermore, the support legs are threaded into threaded grooves with opposite directions of rotation, and the right support legs are movably connected to the wall of the slide rod.

[0012] Furthermore, the top of the placement plate is provided with equidistantly arranged limiting grooves, and two baffles are provided on the top of the placement plate. The bottom of the baffles is fixedly connected to a limiting rod, and the top of each baffle is fixedly connected to a handle.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model places the pipe on top of the placement plate, and the moving mechanism drives the frame to move back and forth above the pipe. After reaching the straightening position, the hydraulic rod is activated, and the hydraulic rod drives the arc-shaped clamping head or square clamping head to move towards the pipe. The arc-shaped clamping head or square clamping head is driven by the fixed component and the moving component for easy installation and disassembly. When encountering a round steel pipe, the arc-shaped clamping head is used for straightening. The shape of the arc-shaped clamping head matches the outer wall of the round pipe, which can ensure a tight fit between the arc-shaped clamping head and the outer wall of the pipe, maximizing the straightening force. When encountering a square steel pipe, the square clamping head is used for straightening. The shape of the square clamping head matches the outer wall of the square pipe, which not only ensures a tight fit between the square clamping head and the outer wall of the pipe, but also ensures that the force is evenly distributed during the clamping process, greatly improving the straightening force brought by using the arc-shaped clamping head.

[0015] 2. This utility model, through the setting of the fixing component, firstly, the worker presses the horizontal plate downwards, the compression spring is squeezed and deforms and contracts, the horizontal plate drives the lower horizontal plate downwards through the movable rod, the lower horizontal plate drives the insertion rod to disengage from the inside of the limiting hole during the downward movement, then the round tube is placed inside the placement groove, the pressing of the horizontal plate is released, the compression spring loses pressure and restores tension, driving the horizontal plate upwards, then the horizontal plate drives the insertion rod to insert into the inside of the limiting hole and the through hole through the movable rod, realizing the convenient installation and disassembly of the arc-shaped clamping head or the square clamping head. When encountering pipes of different shapes, the arc-shaped clamping head and the square clamping head can be easily replaced to be suitable for pipes of different shapes.

[0025] like Figures 1 to 4 As shown, a loading mechanism for a steel pipe straightening machine includes a base 1. A slide 2 is provided on the top of the base 1. Equally spaced fixed seats 3 are fixedly connected inside the slide 2. A placement plate 301 is fixedly connected to the top of each fixed seat 3. Slide grooves 4 are provided on the left and right sides of the base 1. A frame 401 is movably connected inside each slide groove 4. A moving mechanism 402 is installed inside each slide groove 4. A top plate 412 is fixedly connected between the frames 401. Rectangular holes 408 are provided on the sides of the frames 401 that are close to each other. A screw drive mechanism 409 is installed inside each rectangular hole 408. A movable block 41 is movably connected to the output end of the screw drive mechanism 409. Hydraulic rods 403 are fixedly connected to the side of the movable block 410 that is far apart from each other and to the top of the top plate 412. A longitudinal circular tube 404 is fixedly connected inside the output end of the hydraulic rod 403. Through holes 405 are opened on the upper and lower sides of both ends of the circular tube 404. A fixing plate 406 is provided at the bottom of the hydraulic rod 403. An arc-shaped clamping head 407 or a square clamping head 411 is fixedly connected to the top of the fixing plate 406. A fixing component 5 is provided on the top of the base 1 for easy disassembly of the arc-shaped clamping head 407 or the square clamping head 411. A moving component 6 is provided on the top of the base 1 for assisting in the disassembly of the arc-shaped clamping head 407 or the square clamping head 411.

[0026] It should be noted that when the pipe is placed on top of the placement plate 301, the moving mechanism 402 drives the frame 401 to move back and forth above the pipe. After reaching the straightening position, the hydraulic rod 403 is activated, which drives the arc-shaped clamping head 407 or the square clamping head 411 to move towards the pipe. The arc-shaped clamping head 407 or the square clamping head 411 is driven by the fixing component 5 and the moving component 6 for easy installation and disassembly. This allows for straightening using the arc-shaped clamping head 407 when encountering round steel pipes. The shape of 7 matches the outer wall of the circular pipe, ensuring a tight fit between the arc-shaped clamping head 407 and the outer wall of the pipe, maximizing the straightening force. When encountering a square steel pipe, the square clamping head 411 is used for straightening. The shape of the square clamping head 411 matches the outer wall of the square pipe, ensuring not only a tight fit between the square clamping head 411 and the outer wall of the pipe, but also ensuring uniform force distribution during the clamping process, greatly improving the straightening force brought by using the arc-shaped clamping head 407.

[0027] The fixing component 5 includes a rectangular block 501 at one end of a circular tube 404 that is far apart from each other. A placement groove 502 is provided on the side of the rectangular block 501 near the circular tube 404. The circular tube 404 is located inside the placement groove 502. Three equidistant limiting holes 503 are provided inside the rectangular block 501. Movable rods 504 are movably connected inside each of the far apart limiting holes 503. Horizontal plates 505 are fixedly connected to the upper and lower ends of the movable rods 504. An insertion rod 506 is fixedly connected to the top of the lower horizontal plate 505. The insertion rod 506 is located inside the through hole 405. Compression springs 507 are provided on the upper end of the outer wall surface of the movable rods 504. The output end of the compression spring 507 is in contact with the top of the rectangular block 501.

[0028] It should be noted that, firstly, the operator presses the horizontal plate 505 downwards, causing the compression spring 507 to be squeezed and deformed. The horizontal plate 505 moves downwards via the movable rod 504, causing the lower horizontal plate 505 to move downwards. During the downward movement, the lower horizontal plate 505 causes the insertion rod 506 to disengage from the interior of the limiting hole 503. Then, the round tube 404 is placed inside the placement slot 502. The pressure on the horizontal plate 505 is released, and the compression spring 507 loses pressure and restores tension, causing the horizontal plate 505 to move upwards. Subsequently, the horizontal plate 505, via the movable rod 504, causes the insertion rod 506 to be inserted into the interior of the limiting hole 503 and the through hole 405, thus facilitating the installation and removal of the arc-shaped clamping head 407 or the square clamping head 411. When encountering pipes of different shapes, the arc-shaped clamping head 407 and the square clamping head 411 can be easily replaced to suit different pipe shapes.

[0029] The movable component 6 includes support legs 601 fixedly connected to the left and right sides of the rectangular block 501. A rectangular groove 602 is provided on the top of the fixed plate 406. A stepper motor 603 is fixedly connected to the front side of the fixed plate 406. A rotating shaft 604 is fixedly connected to the output end of the stepper motor 603. The front and rear ends of the outer wall of the rotating shaft 604 are provided with threaded grooves 605 with opposite directions of rotation. A slide rod 606 is fixedly connected inside the fixed plate 406. The left support legs 601 are threadedly connected to the threaded grooves 605 with opposite directions of rotation, and the right support legs 601 are movably connected to the wall of the slide rod 606.

[0030] It should be noted that when the external controller is started, the stepper motor 603 starts and drives the rotating shaft 604 to rotate in the opposite direction through the output end. During the rotation, the rotating shaft 604 drives the support leg 601 to move through the threaded groove 605. The movement trajectory of the support leg 601 on the other side is limited by the slide rod 606, so that the support leg 601 drives the rectangular block 501 to move in opposite directions until the round tube 404 is disengaged from the interior of the placement groove 502. The stepper motor 603 stops starting, and the fixed relationship between the arc-shaped clamping head 407 or the square clamping head 411 and the hydraulic rod 403 is released.

[0031] The top of the placement plate 301 is provided with equidistantly arranged limiting grooves 302. The top of the placement plate 301 is provided with two baffles 303. The bottom of the baffles 303 is fixedly connected to a limiting rod 304. The limiting rod 304 is located inside any limiting groove 302. The top of each baffle 303 is fixedly connected to a handle 305.

[0032] It should be noted that the baffle 303 can be removed from the inside of the limiting groove 302 by using the handle 305, and the distance between the baffles 303 can be adjusted arbitrarily by using multiple limiting grooves 302. The distance between the baffles 303 can be adjusted to accommodate steel pipes of different shapes and specifications.

[0033] In summary: The pipe is placed on top of the placement plate 301. The moving mechanism 402 drives the frame 401 to move back and forth above the pipe. After reaching the straightening position, the hydraulic rod 403 is activated, driving the arc-shaped clamping head 407 or the square clamping head 411 towards the pipe. The arc-shaped clamping head 407 or the square clamping head 411 is easily installed and removed via the fixed component 5 and the moving component 6. This allows for straightening of round steel pipes using the arc-shaped clamping head 407. The shape matches the outer wall of the circular pipe, ensuring a tight fit between the arc-shaped clamping head 407 and the outer wall of the pipe, maximizing the straightening force. When encountering a square steel pipe, the square clamping head 411 is used for straightening. The shape of the square clamping head 411 matches the outer wall of the square pipe, ensuring not only a tight fit between the square clamping head 411 and the outer wall of the pipe, but also ensuring uniform force distribution during the clamping process, greatly improving the straightening force brought by using the arc-shaped clamping head 407.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
