Abstract
Description
Technical Field
[0001] This utility model relates to the field of building material lifting technology, specifically a steel pipe fixing device for lifting building materials. Background Technology
[0002] When decorating the interior of a building, scaffolding of varying heights is required depending on the wall's height. The scaffolding is constructed of steel pipes, which need to be transported upwards during erection. Currently, there are no specialized clamps for securing the steel pipes, so ropes are typically used for hoisting. The common method involves connecting the steel pipes to the ropes by wrapping and knotting them together, then using the ropes to lift the pipes upwards. However, this method of securing the steel pipes by wrapping and knotting is ineffective, leading to slippage during lifting, increasing the risk of accidents. Furthermore, the complex steps involved in this method affect the efficiency of hoisting and transporting. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a steel pipe fixing device for lifting construction materials. It solves the problems of poor fixing effect of steel pipes by rope wrapping and knotting, which leads to slippage of steel pipes during lifting. The rope wrapping and knotting fixing method is also complicated in connection steps, affecting the lifting and conveying efficiency.
[0005] (II) Technical Solution
[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel pipe fixing device for lifting building materials, including a horizontal frame, a vertical connecting rod installed at the right end of the horizontal frame, a top tie rod installed on the left side wall of the vertical connecting rod near the top, a connecting ring installed on the outer wall of the top tie rod near the middle, and a fixing device installed on the outer wall of the horizontal frame near the left side.
[0007] The fixing device includes a positioning plate, a right-turning ring, a rear connecting rod, a rear support rod, a left-turning ring, a front connecting rod, a front support rod, a fastening rope, a rear electromagnet, and a front electromagnet. The positioning plate is installed on the outer wall of the crossbeam and located at the left end. The right-turning ring is rotatably installed on the outer wall of the positioning plate via a bearing and located slightly to the right of the center. The rear connecting rod is installed on the outer wall of the right-turning ring. The rear support rod is installed on the front side wall of the rear connecting rod and located at the bottom end. The left-turning ring is rotatably installed on the outer wall of the positioning plate via a bearing and located slightly to the left of the center. The front connecting rod is installed on the outer wall of the left-turning ring. The front support rod is installed on the rear side wall of the front connecting rod and located at the bottom end. The fastening rope is installed on the end of the front support rod away from the front connecting rod. The end of the fastening rope away from the front support rod is installed on the end of the rear support rod away from the rear connecting rod. The rear electromagnet is installed inside the rear connecting rod, and the front electromagnet is installed inside the front connecting rod.
[0008] Preferably, the fastening rope is made of steel wire.
[0009] Preferably, the fastening rope is covered with a rubber sleeve, and the surface of the rubber sleeve is polished to a frosted finish.
[0010] Preferably, the rear electromagnet has the same front pole as the front electromagnet.
[0011] Preferably, a connecting groove is formed on the outer surface of the connecting ring at the middle position.
[0012] Preferably, the angle between the rear support rod and the rear connecting rod is 45°, and the angle between the front connecting rod and the front support rod is 45°.
[0013] Compared with the prior art, this utility model provides a steel pipe fixing device for lifting materials in construction engineering, which has the following beneficial effects:
[0014] 1. This steel pipe fixing device for material lifting in construction engineering involves manually pushing the steel pipe upwards from below the rear and front support rods. The steel pipe pushes the front and rear support rods to open to the left and right, stretching the fastening rope into an "n" shape. The steel pipe moves from between the rear and front support rods to above them, moving to the inside of the fastening rope. Then, the rear and front support rods move towards the center, placing them below the steel pipe, allowing the end of the fastening rope to pass under the bottom of the pipe. The hand support is then released, causing the steel pipe to press downwards against the rear and front support rods. Under pressure, the rear support rod moves forward, and the front support rod moves backward. Simultaneously, the forward pull of the rear support rod and the backward pull of the front support rod wrap the fastening rope around the outside of the steel pipe, locking it in place and preventing slippage. This improves the stability of the connection.
[0015] 2. When the steel pipe fixing device for lifting materials in this construction project is released after being hoisted to a designated height, the rear electromagnet and the front electromagnet are energized. The repulsive force between the rear electromagnet and the front electromagnet pushes the rear connecting rod and the front connecting rod away from each other. The rear connecting rod drives the rear support rod to move backward, and the front connecting rod drives the front support rod to move forward. This causes the rear support rod and the front support rod to move and open to the front and rear sides, allowing the steel pipe to fall downward between the rear support rod and the front support rod. The unloading operation is convenient and improves the efficiency of hoisting work. In addition, the device is small in size, widely applicable, and convenient for manual hoisting work using ropes in small spaces. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-4 This utility model provides a steel pipe fixing device for lifting building materials, including a horizontal frame 1, a vertical connecting rod 2 installed at the right end of the horizontal frame 1, a top tie rod 3 installed on the left side wall of the vertical connecting rod 2 near the top, a connecting ring 4 installed on the outer wall of the top tie rod 3 near the middle, and a fixing device installed on the outer wall of the horizontal frame 1 near the left side.
[0023] The fixing device includes a positioning plate 5, a right-turning ring 6, a rear connecting rod 7, a rear support rod 8, a left-turning ring 9, a front connecting rod 10, a front support rod 11, a fastening rope 12, a rear electromagnet 13, and a front electromagnet 14. The positioning plate 5 is installed on the outer wall of the crossbeam 1 at the left end. The right-turning ring 6 is rotatably installed on the outer wall of the positioning plate 5 via a bearing at a position slightly to the right of the center. The rear connecting rod 7 is installed on the outer wall of the right-turning ring 6. The rear support rod 8 is installed on the front side wall of the rear connecting rod 7 at the bottom end. The left-turning ring 9 is rotatably mounted on the outer wall of the positioning plate 5 via a bearing and located slightly to the left of the center. The front connecting rod 10 is mounted on the outer wall of the left-turning ring 9. The front support rod 11 is mounted on the rear side wall of the front connecting rod 10 and located near the bottom. The fastening rope 12 is mounted on the end of the front support rod 11 away from the front connecting rod 10. The end of the fastening rope 12 away from the front support rod 11 is mounted on the end of the rear support rod 8 away from the rear connecting rod 7. The rear electromagnet 13 is installed inside the rear connecting rod 7. The front electromagnet 14 is installed inside the rear connecting rod 7. Inside the front connecting rod 10, the steel pipe is pushed upwards from below the rear support rod 8 and the front support rod 11 by hand. This pushes the front support rod 11 and the rear support rod 8 to open to the front and rear sides, stretching the fastening rope 12 into an n-shape. The steel pipe moves from between the rear support rod 8 and the front support rod 11 to above them, moving to the inside of the fastening rope 12. Then, the rear support rod 8 and the front support rod 11 move towards the center, bringing them below the steel pipe and tightening the rope. The end of the securing rope 12 moves past the bottom of the steel pipe, and then the hand support on the steel pipe is released, causing the steel pipe to press down on the rear support rod 8 and the front support rod 11. Under the pressure, the rear support rod 8 moves forward, and the front support rod 11 moves backward. At the same time, the forward pulling force of the rear support rod 8 and the backward pulling force of the front support rod 11 wrap the securing rope 12 around the outside of the steel pipe to lock the steel pipe, thereby preventing the steel pipe from sliding in the left and right directions and slipping off, thus improving the stability of the connection.
[0024] Furthermore, the fastening rope 12 is made of steel wire, which allows the fastening rope 12 to be bent, and the steel pipe is fixed by wrapping the fastening rope 12 around the outside of the steel pipe.
[0025] Furthermore, the outer layer of the fastening rope 12 is covered with a rubber sleeve, the surface of which is polished to a frosted finish to increase the friction between the steel pipe and the fastening rope 12, thereby preventing the steel pipe from sliding left and right.
[0026] Furthermore, the rear electromagnet 13 has the same front pole as the front electromagnet 14. When the device is released after being hoisted to a designated height, the rear electromagnet 13 and the front electromagnet 14 are energized. The repulsive force between the rear electromagnet 13 and the front electromagnet 14 pushes the rear connecting rod 7 and the front connecting rod 10 away from each other. The rear connecting rod 7 drives the rear support rod 8 to move backward, and the front connecting rod 10 drives the front support rod 11 to move forward. This causes the rear support rod 8 and the front support rod 11 to move and open to the front and rear sides, allowing the steel pipe to fall downward between the rear support rod 8 and the front support rod 11. This makes the unloading operation convenient and improves the efficiency of hoisting work. In addition, the device is small in size and widely applicable, making it convenient for manual hoisting work using ropes in small spaces.
[0027] Furthermore, a connecting groove is provided on the outer surface of the connecting ring 4 at the middle position to facilitate the connection and installation of the hoisting telescopic mechanism with the connecting ring 4.
[0028] Furthermore, the angle between the rear support rod 8 and the rear connecting rod 7 is 45°, and the angle between the front connecting rod 10 and the front support rod 11 is 45°, so that when the steel pipe is pressed on top of the rear support rod 8 and the front support rod 11, the rear support rod 8 and the front support rod 11 move closer to the middle under the action of the weight of the steel pipe.
[0029] In use, the rope is fitted and fixed to the groove on the surface of the connecting ring 4. When fixing the steel pipe, the steel pipe is pushed upward from below the rear support rod 8 and the front support rod 11 by hand. The steel pipe pushes the front support rod 11 and the rear support rod 8 to open to the front and rear sides, stretching the fastening rope 12 into an n-shape. The steel pipe moves from between the rear support rod 8 and the front support rod 11 to above the rear support rod 8 and the front support rod 11, and moves to the inside of the fastening rope 12. Then, the rear support rod 8 and the front support rod 11 move towards the middle, so that the rear support rod 8 and the front support rod 11 move to the bottom of the steel pipe, so that the end of the fastening rope 12 moves past the bottom of the steel pipe. Then, the hand support on the steel pipe is released, so that the steel pipe presses down on the rear support rod 8 and the front support rod 11. The rear support rod 8 moves forward under the pressure, and the front support rod 11 moves backward under the pressure. At the same time, the rear support rod 8 pulls forward. The force and the backward pulling force of the front support rod 11 will wrap the fastening rope 12 around the outside of the steel pipe to lock the steel pipe. With the cooperation of the two fixing devices on the left and right, the steel pipe is fixed. Then, the device is moved by the rope hoisting. When the device is released after being hoisted to the designated height, the rear electromagnet 13 and the front electromagnet 14 are energized. The repulsive force between the rear electromagnet 13 and the front electromagnet 14 pushes the rear connecting rod 7 and the front connecting rod 10 away. The rear connecting rod 7 drives the rear support rod 8 to move backward, and the front connecting rod 10 drives the front support rod 11 to move forward. This causes the rear support rod 8 and the front support rod 11 to move and open to the front and rear sides, so that the steel pipe falls down between the rear support rod 8 and the front support rod 11. The unloading operation is convenient and can improve the efficiency of hoisting work. In addition, the device is small in size and has wide applicability, which is convenient for manual hoisting work using ropes in small spaces.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
