Description
Technical Field
[0001] The utility model relates to the field of bending devices, in particular to a bending device which is easy to fix for buried pipes. Background Art
[0002] A pipeline is a device connected by pipes, pipe connectors and valves for transporting gas, liquid or fluid with solid particles. Pipes are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, water conservancy projects and various industrial installations. In various complex piping systems, in order to adapt to complex usage occasions, it is necessary to use pipe bending equipment to bend the pipe.
[0003] Most pipe bending devices are composed of parts such as a machine body, a fixing device and a bending equipment. After the worker places the pipe to be bent on the end face of the machine body, the pipe is fixed and restricted by the fixing device. The worker turns the handle of the bending equipment to bend the pipe to a specific angle according to specific requirements. Once the bending is completed, the restriction can be removed and the pipe can be taken out.
[0004] However, when bending pipes, most existing bending equipment often requires workers to manually activate air pressure or hydraulic limit devices to fix and limit the pipes to ensure that the position of the pipes will not shift when subjected to force. This fixing method requires workers to repeatedly fix and remove each pipe when bending it, which affects the bending efficiency of the pipes. At the same time, repeated disassembly of the pipes can easily lead to high work intensity for the workers. Utility Model Content
[0005] Based on this, the purpose of the utility model is to provide a bending device for an buried pipe that is easy to fix, so as to solve the technical problems mentioned in the above background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bending device for an buried pipe that is easy to fix, comprising a body and a bending device, a protrusion is movably installed inside the body, and a first rack is fixedly installed on one end of the protrusion, a second gear is movably installed inside the body, and a first gear meshing with the first rack is fixedly installed on one end of the second gear, a second rack meshing with the second gear is movably installed inside the body, and a first connecting plate is fixedly installed on one end of the second rack, a movable clamp is fixedly installed on one end of the first connecting plate, and a movable groove for limiting the first connecting plate is opened inside the body, a fixing clamp is fixedly installed on one end of the body, and a limiting component for limiting the first rack is fixedly installed inside the body.
[0007] By adopting the above technical scheme, by providing components such as a protrusion, a first rack, a second gear, a first gear and a second rack, when using the equipment, a worker only needs to place the pipe to be bent inside the placement groove and then push the pipe. Through the transmission of the second gear and the first gear, the movable clamp on one side can be driven to move, so as to fix and limit the pipe to be bent, and effectively ensure that the position of the pipe will not be offset during the bending process. Compared with the traditional manual fixing through a hydraulic fixing device, the equipment is more convenient and quick. By placing the pipe for bending, the pipe can be automatically limited, thereby improving its overall bending efficiency and effectively reducing the work intensity of the workers.

[0009] By adopting the above technical solution, the limiting rod cooperates with the limiting groove to ensure that the moving direction of the protrusion inside the body will not be offset, ensuring that it can normally drive the first rack to move. The cross-section of the limiting groove is set to be oblique so that the height of the protrusion will gradually decrease during movement, preventing the protrusion from affecting the movement of the pipe inside the placement groove.
[0010] The utility model is further configured such that a limiting hole is provided inside the first rack, and a limiting block matching the limiting hole is movably installed inside the body, and one side end face of the limiting block is arranged in an arc shape.
[0011] By adopting the above technical solution, the limit block cooperates with the limit hole to fix and limit the first rack, ensuring that the position of the movable clamp will not move during the bending process of the pipe, thereby ensuring the bending effect. One side end face of the limit block is set in an arc shape, so that the first rack will be squeezed when it contacts the limit block, causing the movably installed limit block to move backward to ensure that it will not block the movement of the first rack.
[0012] The utility model is further configured that a fixing rod is fixedly installed at one end of the body, and a movable plate is movably installed at one side of the fixing rod, and the limit block is connected to the fixing rod through the movable plate.
[0013] By adopting the above technical solution, the machine body provides support for the fixed rod, and the movably installed movable plate enables it to move under the restriction of the fixed rod. The fixed rod and the limit block are connected by the movable plate, so that the movable plate will drive the limit block to move when it moves, making it convenient for workers to release the limit of the limit block on the first rack.
[0014] The utility model is further configured that the exterior of the fixed rod is sleeved with a second spring connected to the machine body and the movable plate, and a limit plate for limiting the movable plate is fixedly installed at one end of the fixed rod, and a placement groove is opened inside the machine body.
[0015] By adopting the above technical solution, the second spring is set to continuously apply elastic force to the movable plate to ensure that the limit block is reset when it moves, thereby achieving fixation and limiting. The placement groove can facilitate workers to better locate and place the pipes to be bent, thereby improving bending efficiency.
[0016] The utility model is further configured such that a connecting rod is fixedly installed inside the body, and a connecting block is movably installed at one end of the connecting rod, the first rack is connected to the connecting rod through the connecting block, and the outside of the connecting rod is sleeved with a first spring connected to the body and the connecting block.
[0017] By adopting the above technical solution, the machine body provides support for the connecting rod, and the movably installed connecting block allows it to move within the limit of the connecting rod. The first rack is fixedly connected to the connecting block, so that when the first rack moves, it will drive the connecting block to move together. The setting of the first spring allows the worker to apply elastic force to the connecting block after releasing the limit of the limit block on the first rack, so as to help it drive the first rack to reset, and drive the movable clamp to release the limit and fixation of the bent pipe, making it convenient for workers to pick it up and improving its overall bending efficiency.
[0018] In summary, the utility model mainly has the following beneficial effects:
[0019] 1. The utility model is provided with components such as a convex block, a first rack, a second gear, a first gear and a second rack, so that when using the equipment, the worker only needs to place the pipe to be bent in the placement groove and then push the pipe. Through the transmission of the second gear and the first gear, the movable clamp on one side can be driven to move, so as to fix and limit the pipe to be bent, and effectively ensure that the position of the pipe will not be offset during the bending process. Compared with the traditional manual fixing through a hydraulic fixing device, the equipment is more convenient and quick. By placing the pipe for bending, the pipe can be automatically limited, thereby improving its overall bending efficiency and effectively reducing the work intensity of the workers.
[0020] 2. The utility model provides components such as a limit rod, a limit groove, a limit block, a first spring, a connecting block and a movable plate, so that after the worker pushes the pipe to move a certain distance inside the placement groove, the protrusion is restricted by the limit groove and automatically moves down to prevent it from affecting the movement of the pipe inside the placement groove. At the same time, the limit block can fix and limit the first rack to ensure that the position of the movable clamp will not change or displace during the bending process. At the same time, the first spring can ensure that after the worker releases the limit, the protrusion automatically resets, thereby improving the overall bending efficiency.

When using the equipment, the worker places the pipe to be bent inside the placement groove 23 opened on the end face of the body 1, pushes the pipe to displace it, and drives the first gear 5 to rotate through the first rack 3. When the first gear 5 rotates, it can drive the second rack 6 to displace, and drive the movable clamp 7 to fix and limit the pipe placed inside the placement groove 23 to ensure that the position of the pipe will not shift during the bending process.
[0030] See also Figure 2 - Figure 5 The limiting assembly includes a limiting rod 14, a limiting groove 15, a limiting block 16, a limiting hole 17, a fixed rod 18, a movable plate 19, a second spring 20 and a limiting plate 21. The limiting rod 14 is fixedly installed inside the protrusion 2, and the limiting groove 15 for limiting the limiting rod 14 is opened inside the body 1. The cross-section of the limiting groove 15 is obliquely set. The limiting rod 14 cooperates with the limiting groove 15 to ensure that the moving direction of the protrusion 2 inside the body 1 will not be offset, and it can be ensured that it can normally drive the first rack 3 to move. The cross-section of the limiting groove 15 is obliquely set so that the height of the protrusion 2 will gradually decrease when moving, preventing the protrusion 2 from affecting the movement of the pipe inside the placement groove 23.
[0031] See also Figure 2 - Figure 4 A limiting hole 17 is provided inside the first rack 3, and a limiting block 16 matching the limiting hole 17 is movably installed inside the body 1. One side end face of the limiting block 16 is arranged in an arc shape. The limiting block 16 cooperates with the limiting hole 17 to fix and limit the first rack 3, ensuring that the position of the movable clamp 7 of the pipeline will not move during the bending process, thereby ensuring the bending effect. One side end face of the limiting block 16 is arranged in an arc shape, so that the first rack 3 will be squeezed when it contacts the limiting block 16, so that the movably installed limiting block 16 is displaced backward to ensure that it will not block the movement of the first rack 3.
[0032] See also Figure 2 - Figure 4A fixed rod 18 is fixedly installed at one end of the body 1, and a movable plate 19 is movably installed on one side of the fixed rod 18. The limit block 16 is connected to the fixed rod 18 through the movable plate 19. The body 1 provides support for the fixed rod 18. The movably installed movable plate 19 allows it to move under the restriction of the fixed rod 18. The fixed rod 18 is connected to the limit block 16 through the movable plate 19, so that the movable plate 19 will drive the limit block 16 to move when it moves, which is convenient for workers to release the limit of the limit block 16 on the first rack 3.
[0033] See also Figure 2 - Figure 4 The outer sleeve of the fixed rod 18 is provided with a second spring 20 connected to the body 1 and the movable plate 19, and one end of the fixed rod 18 is fixedly installed with a limit plate 21 for limiting the movable plate 19.

The placement groove 23 can facilitate workers to better locate and place the pipes to be bent, thereby improving the bending efficiency.
[0034] See also Figure 1 - Figure 3 A connecting rod 10 is fixedly installed inside the body 1, and a connecting block 9 is movably installed at one end of the connecting rod 10. The first rack 3 is connected to the connecting rod 10 through the connecting block 9, and the outer sleeve of the connecting rod 10 is provided with a first spring 11 connected to the body 1 and the connecting block 9. The body 1 provides support for the connecting rod 10, and the movably installed connecting block 9 allows it to move within the limit of the connecting rod 10. The first rack 3 is fixedly connected to the connecting block 9, so that when the first rack 3 moves, it will drive the connecting block 9 to move together. The setting of the first spring 11 allows the worker to apply elastic force to the connecting block 9 after releasing the limit block 16 on the first rack 3, helping it to drive the first rack 3 to reset, and drive the movable clamp 7 to release the limit and fixation of the bent pipe, making it convenient for workers to pick it up and improve its overall bending efficiency.
[0035] The working principle of the utility model is as follows: when using the device, a worker places the pipe to be bent inside the placement groove 23 opened on the end face of the machine body 1, pushes the pipe to displace it, and drives the position of the protrusion 2 to displace during its movement, drives the first gear 5 to rotate through the first rack 3, and when the first gear 5 rotates, it can drive the second rack 6 to displace, and drives the movable clamp 7 to fix and limit the pipe placed inside the placement groove 23. During the movement, the protrusion 2 is limited by the limiting rod 14 and the limiting groove 15, and its position drops to ensure that it does not affect the movement of the pipe. When the first rack 3 moves a certain distance After the pipe is separated, the limit block 16 is squeezed, and when it moves to the limit hole 17, the second spring 20 applies a pulling force to it, so that the limit block 16 enters the inside of the limit hole 17, thereby fixing and restricting the first rack 3, ensuring that the position of the pipe will not shift during the bending process. When the bending is completed and the pipe needs to be taken out, the worker pulls the movable plate 19 to make the limit block 16 disengage from the inside of the limit hole 17, and releases the restriction and fixation of the first rack 3. The first spring 11 applies an elastic force to the connecting block 9 to help the protrusion 2 and the first rack 3 to reset, so that the movable clamp 7 releases the restriction on the pipe and it can be taken out to complete the bending.
