[0001] This utility model relates to the field of hydropower installation technology, specifically to a bending auxiliary device for pipe installation. Background Technology

[0002] Pipe bending auxiliary equipment for plumbing and electrical installations is designed to help installers bend PVC, PPR, and other plastic pipes more effortlessly, accurately, and aesthetically. Primarily using externally shaped manual pipe benders, it can bend pipes at specific angles while ensuring roundness. These tools effectively improve installation efficiency, guarantee bending quality, and avoid material waste, making them essential auxiliary tools in modern professional plumbing and electrical construction.

[0003] A bending auxiliary device for hydropower installation disclosed in Chinese Patent Publication No. CN217021409U pushes the hydropower installation pipe into contact with the first rolling mechanism. Under the action of the motor, the threaded shaft can be driven to rotate. Under the threaded connection, the second support plate can be pushed to slide inward, thereby pushing the second rolling mechanism into contact with the pipe. Under the action of force, the pipe can be bent.

[0004] However, bending auxiliary equipment has limited functionality. After bending the pipe, it is necessary to manually push the pipe to move it in order to facilitate subsequent bending work. This operation is time-consuming and labor-intensive, affecting the overall working efficiency and effectiveness of the bending auxiliary equipment. Utility Model Content

[0005] The purpose of this invention is to provide a bending auxiliary device for pipe installation, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bending auxiliary device for pipe installation, comprising a workbench, a controller fixedly connected to the front end of the left side of the upper surface of the workbench, a first clamping mechanism provided at the rear end of the left side of the upper surface of the workbench, a rotating mechanism provided at the center of the right side inside the workbench, a turntable provided at the top of the rotating mechanism, a second clamping mechanism provided at the top of the turntable, and a pushing mechanism for feeding the pipe after bending.

[0007] Preferably, the first clamping mechanism includes a first auxiliary roller that is equidistantly and uniformly rotatably connected to the left side of the upper surface of the worktable. A fixed plate is fixedly connected to the rear end of the left side of the upper surface of the worktable. Electric push rods are fixedly connected to the left and right sides of the front end of the fixed plate. Connecting seats are fixedly connected to the front ends of the two electric push rods. A second auxiliary roller is equidistantly and uniformly rotatably connected to the interior of the front end of the connecting seat.

[0008] Preferably, the rotating mechanism includes a first servo motor fixedly connected to the center position of the right side inside the worktable, and a ratchet is installed at the output shaft end of the first servo motor, with the top end of the ratchet being concentrically fixed to the turntable.

[0009] Preferably, the second clamping mechanism includes a positioning seat fixed at the center of the top of the turntable, a second servo motor fixed at the center of the rear end inside the turntable, a threaded rod installed on the output shaft end of the second servo motor, a threaded block connected to the external thread of the threaded rod, and a clamping block fixed at the top of the threaded block.

[0010] Preferably, the contact surfaces of the positioning seat and the clamping block are provided with interlocking grooves.

[0011] Preferably, the pushing mechanism includes a first sprocket disposed outside the ratchet, a pawl assembly disposed at the rear end inside the first sprocket, a chain engaged with the outside of the first sprocket, a second sprocket engaged with the inside of the left side of the chain, a first gear concentrically fixed to the top of the second sprocket, a second gear engaged with the right side of the first gear, and the top of the second gear concentrically fixed to the second first auxiliary roller from left to right at the top of the worktable.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This type of bending auxiliary equipment for pipe installation features a clamping block at the top of a turntable. A second servo motor inside the turntable drives a threaded rod to rotate. The threaded block on the threaded rod moves the clamping block, which, in conjunction with a positioning seat, clamps the pipe at the bending point. Simultaneously, a first clamping mechanism at the top of the worktable clamps the pipe's tail end. The first servo motor then drives a ratchet to rotate clockwise around the turntable, allowing for rapid pipe bending. After bending, the clamping block releases the limit on the pipe's bending point, and the second servo motor... A servo motor drives a ratchet and a turntable to rotate counterclockwise, enabling the turntable to quickly reset. Simultaneously, the counterclockwise rotation of the ratchet moves the pawl assembly inside the first sprocket, causing the first sprocket to rotate. At this time, the first sprocket drives the second sprocket to rotate via a chain. The second sprocket then drives the first gear at the top to rotate counterclockwise, and the first gear, through the second gear, drives the first auxiliary roller at the top to rotate clockwise. This pushes the pipe clamped in the first clamping mechanism to be quickly fed, facilitating subsequent rapid bending operations and effectively improving the overall functionality and flexibility of the bending auxiliary equipment.

[0021] like Figure 1-4 As shown, this utility model has the following two specific embodiments.

[0022] Example 1

[0023] A bending auxiliary device for pipe installation includes a workbench 1. A controller 101 is fixedly connected to the front end of the left side of the upper surface of the workbench 1. A first clamping mechanism is provided at the rear end of the left side of the upper surface of the workbench 1. A rotating mechanism is provided at the center of the right side inside the workbench 1. A turntable 4 is provided at the top of the rotating mechanism. A second clamping mechanism is provided at the top of the turntable 4. The device also includes a pushing mechanism for feeding pipes after bending. The controller 101 can control and start the internal electrical equipment of the bending auxiliary device.

[0024] The first clamping mechanism includes a first auxiliary roller 102 that is equidistantly and uniformly rotatably connected to the left side of the upper surface of the worktable 1. A fixed plate 2 is fixedly connected to the rear end of the left side of the upper surface of the worktable 1. Electric push rods 201 are fixedly connected to the left and right sides of the front end of the fixed plate 2. A connecting seat 202 is fixedly connected to the front end of the two electric push rods 201. A second auxiliary roller 203 is equidistantly and uniformly rotatably connected to the interior of the front end of the connecting seat 202. When the electric push rods 201 are activated, they can push the connecting seat 202 to move. At this time, the second auxiliary roller 203 inside the connecting seat 202 can cooperate with the first auxiliary roller 102 to stably clamp and limit the tail end of the pipe that needs to be bent.

[0025] The rotating mechanism includes a first servo motor 3 fixedly connected to the center position on the right side inside the worktable 1. A ratchet 301 is installed on the output shaft end of the first servo motor 3. The top end of the ratchet 301 is concentrically fixed to the turntable 4. When the first servo motor 3 is started, it can drive the turntable 4 to rotate through the ratchet 301.

[0026] The second clamping mechanism includes a positioning seat 401 fixed at the center of the top of the turntable 4, a second servo motor 5 fixed at the center of the rear end inside the turntable 4, a threaded rod 501 installed on the output shaft end of the second servo motor 5, a threaded block 502 connected to the external thread of the threaded rod 501, and a clamping block 6 fixed at the top of the threaded block 502. When the second servo motor 5 is started, it can drive the threaded rod 501 to rotate. At this time, the threaded block 502 on the threaded rod 501 can drive the clamping block 6 at the top to move, and make the clamping block 6 cooperate with the positioning seat 401 to perform stable clamping work at the bending point of the pipe.

[0027] The contact surfaces of the positioning seat 401 and the clamping block 6 are provided with interlocking grooves, which facilitates efficient clamping and limiting of the pipe.

[0028] Example 2

[0029] The difference from Embodiment 1 is that this embodiment discloses a feeding mechanism for feeding pipes after bending:

[0030] The feeding mechanism includes a first sprocket 7 externally mounted on a ratchet 301, a pawl assembly 701 internally mounted at the rear end of the first sprocket 7, a chain 702 externally meshed with the first sprocket 7, a second sprocket 703 internally meshed with the left side of the chain 702, a first gear 704 concentrically fixed to the top of the second sprocket 703, a second gear 705 meshing with the right side of the first gear 704, and the top of the second gear 705 concentrically fixed to the second first auxiliary roller 102 from left to right on the top of the worktable 1. A first servo motor 3 drives the ratchet 3. When 01 rotates counterclockwise, the ratchet 301 can push the pawl assembly 701 inside the first sprocket 7, and drive the first sprocket 7 to rotate synchronously. At this time, the first sprocket 7 can drive the second sprocket 703 to rotate counterclockwise through the chain 702. At the same time, the first gear 704 at the top of the second sprocket 703 can drive the second gear 705 to rotate clockwise, and drive the first auxiliary roller 102 to rotate clockwise, thereby pushing the clamped tube to perform the feeding operation. Meanwhile, the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0031] In this embodiment, the pipe to be bent is placed on the top of the workbench 1 and positioned between the first auxiliary roller 102, the second auxiliary roller 203, the positioning seat 401, and the clamping block 6. At this time, the electric push rod 201 is activated, which pushes the second auxiliary roller 203 through the connecting seat 202, causing the second auxiliary roller 203 to cooperate with the first auxiliary roller 102 to clamp the tail end of the pipe. Simultaneously, the second servo motor 5 inside the turntable 4 is activated, driving the threaded rod 501 to rotate. The threaded block 502 on the threaded rod 501 then moves the clamping block 6, causing the clamping block 6 to cooperate with the positioning seat 401 to clamp the pipe at the bending point. Meanwhile, the first servo motor 3 drives the ratchet 301 to rotate, causing the ratchet 301 to drive the turntable 4 clockwise. The needle rotation allows for rapid bending of the pipe. After bending, the clamping block 6 removes the limit on the bent part of the pipe, and the first servo motor 3 drives the ratchet 301 to rotate counterclockwise. At this time, the ratchet 301 can drive the turntable 4 to quickly reset. Simultaneously, the first servo motor 3 drives the ratchet 301 to rotate counterclockwise, which in turn pushes the pawl assembly 701 inside the first sprocket 7 and drives the first sprocket 7 to rotate synchronously. At this time, the first sprocket 7 can drive the second sprocket 703 to rotate counterclockwise through the chain 702. At the same time, the first gear 704 at the top of the second sprocket 703 can drive the second gear 705 to rotate clockwise, and drive the first auxiliary roller 102 to rotate clockwise, thereby pushing the clamped pipe to perform the feeding operation.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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 preferred examples and are not intended to limit the utility model.
