Description
Technical Field
[0001] This utility model belongs to the field of fiberglass pipe transportation technology, specifically relating to a handling device for fiberglass pipes. Background Technology
[0002] In the production, manufacturing, warehousing and engineering installation of FRP pipes, the handling of pipes is always a key link affecting construction efficiency and safety. As a composite material product, FRP pipes have the characteristics of being lightweight, corrosion resistant and high-strength.
[0003] For example, CN 109095065B discloses a handling device for water conservancy pipelines. Although the handling device for water conservancy pipelines provided by this invention is flexible in structure, easy to move, has low labor intensity, saves time and effort, and has high handling efficiency, the stability of the pipeline is low because it is only clamped and fixed by clamps, and it is not suitable for pipelines of different diameters, which has certain limitations. Therefore, this utility model provides a handling device for fiberglass pipelines. Utility Model Content
[0004] The purpose of this invention is to provide a handling device for fiberglass pipes to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a handling device for fiberglass pipes, comprising two side frames, the tops of the two side frames being fixedly connected by two fixed frames, a connecting frame being provided between the two fixed frames on opposite sides of the two side frames, two symmetrically arranged fixing members being provided at the bottom of each of the two fixed frames, and a support plate being provided at the bottom of the connecting frame.
[0006] In a preferred embodiment, a motor is fixedly connected to one end of each of the fixing frames, and a double-threaded screw is fixedly connected to the output shaft of the motor. The two fixing components are symmetrically threaded to the outside of the double-threaded screw.
[0007] In a preferred embodiment, the top of the inner cavity of the fixing frame is provided with a first guide rail, and the fixing member includes a threaded block that is slidably connected to the outside of the first guide rail, and the threaded block is threadedly connected to the outside of the double-threaded screw.
[0008] In a preferred embodiment, each of the threaded blocks is provided with an arc-shaped clamping plate at its bottom, and an elastic arc-shaped plate is provided on the inner wall of the curved part of the clamping plate.
[0009] In a preferred embodiment, a second guide rail is fixedly connected to the top of the inner cavity of the connecting frame, and two sliding blocks are symmetrically slidably connected to the outside of the second guide rail. A connecting plate is rotatably connected to the bottom of each of the two sliding blocks, and the other end of each of the two connecting plates is fixedly connected to the top of the support plate.
[0010] In a preferred embodiment, both of the fixing brackets have through grooves on the side facing the connecting bracket, and each of the sliding blocks has a fixing plate fixedly connected to both sides. The other end of each of the two fixing plates is fixedly connected to one side of the threaded block in the corresponding direction. The bottom of the support plate is arc-shaped, and a deformation cavity is formed inside the support plate.
[0011] In a preferred embodiment, each of the two side frames is fixedly connected to an electric telescopic rod on its outer surface, and each electric telescopic rod is provided with a caster wheel at its bottom end.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This handling device for fiberglass pipes forms a flexible clamping interface by setting two sets of relatively moving fixing parts and an elastic arc plate embedded in the arc-shaped clamping plate. It adapts to the slight deformation of the outer wall of the pipe and increases the contact area through elastic deformation during the clamping process. It optimizes the "line contact" of traditional rigid clamping into "surface contact", significantly improving friction and anti-slip performance, and thus can be adapted to pipes with different diameters.
[0014] This handling device for fiberglass pipes, by setting up a support plate, can move the support plate downwards during the clamping process by moving the fixing parts. This allows the support plate to contact the top of the pipe, further limiting the pipe and preventing friction between the pipe and the device during movement. Attached Figure Description

Detailed Implementation
[0019] The present invention will be further described below with reference to the embodiments.
[0020] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.
[0021] Please see Figure 1-3 This utility model provides a handling device for fiberglass pipes, including two side frames 1. The tops of the two side frames 1 are fixedly connected by two fixed frames 3. A connecting frame 4 is provided between the two fixed frames 3 on the opposite side of the two side frames 1. Two symmetrically arranged fixing parts 5 are provided at the bottom of each of the two fixed frames 3. A motor 6 is fixedly connected to one end of each fixed frame 3. A double-threaded screw 302 is fixedly connected to the output shaft of the motor 6. The two fixing parts 5 are symmetrically threaded to the outside of the double-threaded screw 302. A first guide rail 301 is provided at the top of the inner cavity of the fixed frame 3. The fixing part 5 includes a threaded block 501 that is slidably connected to the outside of the first guide rail 301. The threaded block 501 is threaded to the outside of the double-threaded screw 302. An arc-shaped clamping plate 502 is provided at the bottom of each threaded block 501. An elastic arc-shaped plate 503 is provided on the inner wall of the bend of the clamping plate 502. An electric telescopic rod 2 is fixedly connected to the outer side of each of the two side frames 1. A universal wheel 201 is provided at the bottom of each electric telescopic rod 2.
[0022] The transport device is initially in the extended state, with two sets of fixing parts 5 located at the outer ends of the double-threaded screw 302, the support plate 7 in a high position, the electric telescopic rod 2 in the retracted state, and the casters 201 suspended in the air. The entire device is in contact with the ground through the bottom of the side frame 1. The fiberglass pipe is hoisted to the support area of the transport device. The electric telescopic rod 2 is activated, extending it until the casters 201 contact the ground, and the side frame 1 is slightly raised so that the entire device is supported by the casters 201, facilitating subsequent movement. The motors 6 on the two fixing frames 3 are activated, synchronously driving the double-threaded screw 302 to rotate. Since the threads on both sides of the double-threaded screw 302 are in opposite directions, the two fixing parts 5 (through...) The threaded block 501 moves synchronously towards the center along the first guide rail 301. The clamping plate 502 gradually approaches the pipe. After the clamping plate 502 contacts the pipe, the elastic arc plate 503 is compressed and undergoes elastic deformation, forming a flexible fit with the outer wall of the pipe. The contact surface changes from "line contact" to "surface contact". When the clamping force reaches the preset value or the motor 6 reaches the preset torque, the motor 6 stops running, and the pipe is stably clamped. The universal wheel 201 pushes the transport device to the target position. The clamping plate 502 works together to prevent the pipe from shaking or rubbing. After reaching the destination, the motor 6 reverses, the fixing part 5 moves outward to release the pipe, and at the same time the electric telescopic rod 2 retracts, and the device returns to the initial state.
[0023] The elastic arc plate 503 uses composite elastic material, which absorbs the small deformation of the outer wall of the pipe through elastic deformation to achieve "surface contact" clamping. The friction is increased and the anti-slip performance is significantly enhanced, ensuring that the two sets of fixing parts 5 move synchronously and avoiding pipe displacement or damage caused by uneven clamping force. Through the thread pitch design of the double threaded screw 302, it can be adapted to most fiberglass pipes.
[0024] In this embodiment, the bottom of the connecting frame 4 is provided with a support plate 7, the top of the inner cavity of the connecting frame 4 is fixedly connected with a second guide rail 401, two sliding blocks 402 are symmetrically slidably connected to the outside of the second guide rail 401, the bottom of each of the two sliding blocks 402 is rotatably connected with a connecting plate 404, the other end of each of the two connecting plates 404 is fixedly connected to the top of the support plate 7, each of the two fixed frames 3 has a through groove on the side facing the connecting frame 4, each of the two sides of each sliding block 402 is fixedly connected with a fixed plate 403, the other end of each of the two fixed plates 403 is fixedly connected to one side of the threaded block 501 in the corresponding direction, the bottom of the support plate 7 is arc-shaped, and a deformation cavity is opened inside the support plate 7;
[0025] The conveying device is in an unclamped state, the support plate 7 is in a high position (away from the pipe), the sliding block 402 is located at both ends of the second guide rail 401, the connecting plate 404 is in an inclined unfolded state, the fixed plate 403 and the threaded block 501 are not subjected to clamping forces, the motor 6 is started, the double-threaded screw 302 begins to rotate, the threaded block 501 moves synchronously towards the middle along the double-threaded screw 302 under the action of the thread of the double-threaded screw 302 and the guidance of the first guide rail 301. During the movement of the threaded block 501, the fixed plate 403 pulls the sliding block 402 to slide on the second guide rail 401. The fixed plate 403 moves synchronously with the sliding block 402 in the through groove to ensure the stability of power transmission. The sliding of the sliding block 402 causes the bottom end of the connecting plate 404 (the end connected to the support plate 7) to move downward. The connecting plate 404 gradually changes from an inclined state to an approximately vertical state, pushing the support plate 7 down. The arc surface at the bottom of the support plate 7 gradually approaches the top of the pipe.
[0026] During the approach process, the arc-shaped surface design facilitates initial centering and positioning, avoiding a hard collision with the top of the pipe. As the support plate 7 continues to press down, its internal deformation cavity undergoes elastic deformation under the pressure from the top of the pipe. The deformation cavity adaptively adjusts according to the irregular shape of the top of the pipe, ensuring that the support plate 7 fully fits against the top of the pipe. When the clamping plate 502 clamps the pipe under the action of the threaded block 501, the support plate 7 has completely contacted the top of the pipe and provided support force. At this point, the pipe forms a double-limiting structure in the handling device, and the clamping of the clamping plate 502... The combined force of the support plate 7 and the support force of the support plate 7 ensure that there is no longitudinal displacement or lateral swaying of the pipeline during the transportation process. The deformation cavity of the support plate 7 continuously buffers the vibration and impact during the transportation process. After being transported to the target position, the motor 6 reverses, and the double-threaded screw 302 drives the threaded block 501 to move in the opposite direction. The threaded block 501 pushes the sliding block 402 to slide outward through the fixed plate 403. The sliding block 402 drives the connecting plate 404 to move upward, so that the support plate 7 is removed from the top of the pipeline and reset to the high position. At the same time, the clamping plate 502 releases the pipeline, completing one transportation operation.
[0027] The working principle and usage process of this utility model are as follows: First, the transport device is initially in the extended state. The two sets of fixing parts 5 are located at the outer ends of the double-threaded screw 302, the support plate 7 is in a high position, the electric telescopic rod 2 is in the retracted state, and the casters 201 are suspended in the air. The entire device contacts the ground through the bottom of the side frame 1. The fiberglass pipe is hoisted to the support area of the transport device. The electric telescopic rod 2 is activated, extending it until the casters 201 contact the ground, and the side frame 1 is slightly raised so that the entire device is supported by the casters 201, facilitating subsequent movement. The motors 6 on the two fixing frames 3 are activated, synchronously driving the double-threaded screw 302 to rotate. Because the threads on both sides of the double-threaded screw 302 are in opposite directions, the two… The fixing component 5 (via the threaded block 501) moves synchronously towards the center along the first guide rail 301. The clamping plate 502 gradually approaches the pipe. After the clamping plate 502 contacts the pipe, the elastic arc plate 503 is compressed and undergoes elastic deformation, forming a flexible fit with the outer wall of the pipe. The contact surface changes from "line contact" to "surface contact". When the clamping force reaches the preset value or the motor 6 reaches the preset torque, the motor 6 stops running, and the pipe is stably clamped. During the movement of the threaded block 501, the fixing plate 403 pulls the sliding block 402 to slide on the second guide rail 401. The fixing plate 403 moves synchronously with the sliding block 402 in the through groove to ensure the stability of power transmission. The sliding of the sliding block 402 drives the connecting plate. The bottom end of 404 (the end connected to the support plate 7) moves downward, and the connecting plate 404 gradually changes from an inclined state to an approximately vertical state, pushing the support plate 7 down. The arc surface at the bottom of the support plate 7 gradually approaches the top of the pipe. During the approach process, the arc surface design facilitates initial centering and positioning, avoiding a hard collision with the top of the pipe. As the support plate 7 continues to press down, its internal deformation cavity undergoes elastic deformation under the pressure of the top of the pipe. The deformation cavity adaptively adjusts according to the irregular shape of the top of the pipe, so that the support plate 7 fully fits the top of the pipe. When the clamping plate 502 clamps the pipe under the action of the threaded block 501, the support plate 7 has completely contacted the top of the pipe and provided support force. At this time, the pipe... The pipeline forms a double-limiting structure in the transport device. The clamping force of the clamping plate 502 and the supporting force of the support plate 7 work together to ensure that there is no longitudinal displacement or lateral swaying of the pipeline during transport. The deformation cavity of the support plate 7 continuously buffers the vibration and impact during transport. After being transported to the target position, the motor 6 reverses, and the double-threaded screw 302 drives the threaded block 501 to move in the opposite direction. The threaded block 501 pushes the sliding block 402 outward through the fixed plate 403. The sliding block 402 drives the connecting plate 404 to move upward, so that the support plate 7 is separated from the top of the pipeline and reset to the high position. At the same time, the clamping plate 502 releases the pipeline, completing one transport operation. The transport device is then pushed to the target position by the caster wheel 201.
