Description

Technical Field

[0001] The utility model relates to the technical field of transfer devices, in particular to a transfer device for PVC pipes. Background Technique

[0002] The transfer device for PVC pipes is a device used for handling and transporting PVC pipes. It usually consists of a frame and one or more rollers. The PVC pipes can be placed on the frame and then moved to the required position through the rollers. There are various types of transfer devices for PVC pipes, including manual and electric ones. Manual transfer devices are usually relatively simple and inexpensive, suitable for small-scale handling and transportation. Electric transfer devices are more automated and efficient, suitable for large-scale handling and transportation.

[0003] According to a disclosed transfer device for PVC pipes (publication number: CN212952699U), the side clamping plates in the above application do not have a limiting function, and the upper arc plate and the lower arc plate fix the PVC pipes through a starting motor. However, the motor rotates at a high speed, and the PVC pipes themselves have a certain toughness. If the motor is not stopped in time, it is very easy to cause the PVC pipes to be clamped and deformed, resulting in damage to the PVC pipe body. Content of the Utility Model

[0004] The purpose of the utility model is to provide a transfer device for PVC pipes to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A transfer device for PVC pipes, including a transfer frame and a transfer sleeve. A connecting block is fixedly connected to the bottom of the transfer sleeve. A rocker is penetrated and rotatably connected to the inner side of the connecting block. A positioning part for preventing the deformation of the pipe material is arranged inside the transfer sleeve. The positioning part includes:

[0006] A gear disk, which is located inside the transfer sleeve and rotatably connected to the transfer sleeve. An arc-shaped groove is formed on the surface of the gear disk. The rocker is penetrated and fixedly connected with a small gear. The small gear meshes with the gear disk. A fixed disk is fixedly connected to the inner wall of the transfer sleeve. A snap ring is fixedly connected to the inner side of the fixed disk. A linkage column is penetrated and slidably connected to the inner side of the snap ring. A sliding rod is fixedly connected to the surface of the linkage column. The sliding rod penetrates through the arc-shaped groove formed on the surface of the gear disk. When the rocker is rotated, the rocker will drive the gear disk to rotate through the small gear.

[0007] Preferably, the bottom of the linkage column is penetrated and slidably connected with a U-shaped frame. A contact wheel is arranged inside the U-shaped frame. The sliding rod slides in the arc-shaped groove. One end of the sliding rod is fixedly connected with the linkage column. At the same time, the linkage column is limited by the snap ring, so that the linkage column is driven by the sliding rod to move towards the axis of the transfer sleeve.

[0008] Preferably, an anti - detachment plate is fixedly connected to the bottom surface of the linkage column, and the anti - detachment plate is located inside the U - shaped frame.

[0009] Preferably, a push rod penetrates through and is slidably connected to the inside of the linkage column. The bottom end of the push rod is fixedly connected to a cross - plate, and a rubber contact block is fixedly connected to the bottom surface of the cross - plate. When the rocker is further rotated to make the linkage column continue to move, the distance between the anti - detachment plate at the bottom of the linkage column and the cross - plate will gradually shorten. A first spring is fixedly connected between the cross - plate and the anti - detachment plate.

[0010] Preferably, a hinge rod penetrates through the surface of the push rod at the end far from the cross - plate, and the hinge rod is hinged to the push rod.

[0011] Preferably, the end of the hinge rod far from the push rod penetrates through and is hinged to a T - shaped clamping block, and the T - shaped clamping block penetrates through the linkage column and is slidably connected.

[0012] Preferably, a pull rod penetrates through and is slidably connected to the surface of the transfer sleeve. A limiting rack is fixedly connected to one end surface of the pull rod. When the distance between the cross - plate and the anti - detachment plate shortens, the cross - plate relatively pushes the push rod to move. The push rod will relatively push the hinge rod at the top of the push rod to rotate. A pull ring is fixedly connected to the other end of the pull rod, and a second spring is fixedly connected between the pull ring and the transfer sleeve.

[0013] Compared with the prior art, the present utility model provides a transfer device for PVC pipes, which has the following beneficial effects:

[0014] 1. For the transfer device for PVC pipes, when the rocker is rotated to make the linkage column continue to move, the distance between the anti - detachment plate at the bottom of the linkage column and the cross - plate will gradually shorten. The rubber contact block on the bottom surface of the cross - plate will tightly clamp the rotating shaft of the contact wheel, making the contact wheel temporarily unable to rotate, ensuring that the contact wheel can tightly clamp the PVC. At the same time, when the distance between the cross - plate and the anti - detachment plate shortens, the cross - plate relatively pushes the push rod to move. The push rod will relatively push the hinge rod at the top of the push rod to rotate. Subsequently, the rotating hinge rod will gradually push the T - shaped clamping block into the tooth of the limiting rack, thereby making the linkage column unable to continue to move, avoiding the PVC pipe being clamped too tightly by the contact wheel and causing the PVC pipe to be concave - deformed.

[0015] 2. For the transfer device for PVC pipes, through the contact wheels arranged in a circumferential array at both ends of the transfer sleeve, not only can PVC pipes of different sizes be transferred, but also both ends of the PVC pipes can be lifted, avoiding the PVC pipes being distorted due to their own toughness and sagging for too long.

Specific embodiments

[0023] As Figures 1 - 6 shown, the present utility model provides a technical solution: a transfer device for PVC pipes, including a transfer rack 1 and a transfer sleeve 3. A connecting block 4 is fixedly connected to the bottom of the transfer sleeve 3. The inside of the connecting block 4 penetrates and is rotatably connected to a rocker 5. A positioning part 2 for preventing the deformation of the pipe is arranged inside the transfer sleeve 3. The positioning part 2 includes: a gear disk 21, an arc groove 22, a pinion 23, a fixed disk 24, a snap ring 25, a linkage column 26, a slide bar 27, a U-shaped frame 28, an anti-disengagement plate 29, an abutting wheel 210, a push rod 211, a cross plate 212, a rubber abutting block 213, a hinge rod 214, a T-shaped clamping block 215, a first spring 216, a pull rod 217, a limit rack 218, a pull ring 219, and a second spring 220.

[0024] The gear disk 21 is located inside the transfer sleeve 3 and is rotatably connected to the transfer sleeve 3. An arc-shaped groove 22 is formed on the surface of the gear disk 21. The rocker 5 penetrates and is fixedly connected with a pinion 23, and the pinion 23 meshes with the gear disk 21. A fixed disk 24 is fixedly connected to the inner wall of the transfer sleeve 3, and a snap ring 25 is fixedly connected to the inner side of the fixed disk 24. A linkage column 26 penetrates and is slidably connected to the inner side of the snap ring 25. A slide bar 27 is fixedly connected to the surface of the linkage column 26, and the slide bar 27 penetrates the arc-shaped groove 22 formed on the surface of the gear disk 21. When transporting the PVC pipe, the PVC is inserted through the transfer sleeve 3, and then the rocker 5 is rotated. When the rocker 5 rotates, it will drive the gear disk 21 to rotate through the pinion 23. When the gear disk 21 rotates, it will contact the slide bar 27 inside the arc-shaped groove 22 through the arc-shaped groove 22, thereby forcing the slide bar 27 to slide inside the arc-shaped groove 22. The bottom of the linkage column 26 penetrates and is slidably connected to a U-shaped frame 28, and a contact wheel 210 is arranged inside the U-shaped frame 28. The slide bar 27 slides inside the arc-shaped groove 22, and one end of the slide bar 27 is fixedly connected to the linkage column 26. At the same time, the linkage column 26 is limited by the snap ring 25, so that the linkage column 26 is driven by the slide bar 27 to move towards the axis of the transfer sleeve 3, and the linkage column 26 will gradually drive the U-shaped frame 28 at the bottom and the contact wheel 210 inside the U-shaped frame 28 to fit the surface of the PVC pipe.

[0025] A anti-disengagement plate 29 is fixedly connected to the bottom surface of the linkage column 26, and the anti-disengagement plate 29 is located inside the U-shaped frame 28. A push rod 211 penetrates and is slidably connected to the inside of the linkage column 26. The bottom end of the push rod 211 is fixedly connected to a cross plate 212, and a rubber contact block 213 is fixedly connected to the bottom surface of the cross plate 212. When the rocker 5 is continuously rotated to make the linkage column 26 continue to move, the distance between the anti-disengagement plate 29 at the bottom of the linkage column 26 and the cross plate 212 will gradually shorten, and the rubber contact block 213 on the bottom surface of the cross plate 212 will clamp the rotating shaft of the contact wheel 210, so that the contact wheel 210 cannot rotate temporarily. A first spring 216 is fixedly connected between the cross plate 212 and the anti-disengagement plate 29.

[0026] One end surface of the push rod 211 away from the cross plate 212 is penetrated by a hinge rod 214, and the hinge rod 214 is hinged to the push rod 211. One end of the hinge rod 214 away from the push rod 211 penetrates and is hinged with a T-shaped block 215, and the T-shaped block 215 penetrates through the linkage column 26 and is slidably connected. The surface of the transfer sleeve 3 is penetrated and slidably connected with a pull rod 217. One end surface of the pull rod 217 is fixedly connected with a limit rack 218. When the distance between the cross plate 212 and the anti-disengagement plate 29 is shortened, the cross plate 212 relatively pushes the push rod 211 to move. The push rod 211 will relatively push the hinge rod 214 at the top of the push rod 211 to rotate. Subsequently, the rotating hinge rod 214 will gradually push the T-shaped block 215 into the teeth of the limit rack 218, so that the linkage column 26 cannot continue to move. The other end of the pull rod 217 is fixedly connected with a pull ring 219, and a second spring 220 is fixedly connected between the pull ring 219 and the transfer sleeve 3.

[0027] Based on the above embodiment, when transporting the PVC pipe, insert the PVC through and into the transfer sleeve 3, and then rotate the rocker 5. When the rocker 5 rotates, it will drive the gear disc 21 to rotate through the pinion 23. When the gear disc 21 rotates, it will abut against the slide bar 27 inside the arc groove 22 through the arc groove 22, thereby forcing the slide bar 27 to slide within the arc groove 22. One end of the slide bar 27 is fixedly connected with the linkage column 26. At the same time, the linkage column 26 is limited by the snap ring 25, so that the linkage column 26 is driven by the slide bar 27 to move towards the axis of the transfer sleeve 3. The linkage column 26 will gradually drive the U-shaped bracket 28 at the bottom and the abutting wheel 210 inside the U-shaped bracket 28 to fit the surface of the PVC pipe. When continuing to rotate the rocker 5 to make the linkage column 26 continue to move, the distance between the anti-disengagement plate 29 at the bottom of the linkage column 26 and the cross plate 212 will gradually shorten. The rubber abutting block 213 on the bottom surface of the cross plate 212 will clamp the rotating shaft of the abutting wheel 210, so that the abutting wheel 210 cannot rotate temporarily, ensuring that the abutting wheel 210 can clamp the PVC tightly. At the same time, when the distance between the cross plate 212 and the anti-disengagement plate 29 is shortened, the cross plate 212 relatively pushes the push rod 211 to move. The push rod 211 will relatively push the hinge rod 214 at the top of the push rod 211 to rotate. Subsequently, the rotating hinge rod 214 will gradually push the T-shaped block 215 into the teeth of the limit rack 218, so that the linkage column 26 cannot continue to move, preventing the abutting wheel 210 from clamping the PVC pipe too tightly and causing the PVC pipe to be concave and deformed.

[0028] Through the abutting wheels 210 arranged in a circumferential array at both ends of the transfer sleeve 3, not only can PVC pipes of different sizes be transported, but also both ends of the PVC pipes can be lifted, preventing the PVC pipes from sagging for too long due to their own toughness and causing the pipes to be distorted and deformed.

[0029] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit of the present utility model are within the protection scope of the present utility model.
