Technical Field

[0001] The utility model relates to the technical field of traction machines, in particular to a multi-track plastic pipe traction machine. Background Art

[0002] The multi-track plastic pipe tractor is a mechanical device specially used for traction of plastic pipes. With the continuous development of modern engineering construction, plastic pipes are widely used in various fields, such as water supply and drainage pipelines, gas pipelines, power communication pipelines, etc. In the production process of plastic pipes, in order to improve production efficiency and quality, a tractor is needed to help pull the plastic pipes out of the extruder.

[0003] At present, there are some shortcomings in the multi-track plastic pipe traction machines on the market: when adjusting the size of the traction pipe, the general multi-track plastic pipe traction machine uses multiple separate hydraulic cylinders to push the traction mechanism to achieve the function of adjusting the size of the traction pipe. However, when adjusting the size of the traction pipe, the multiple separate hydraulic cylinders make it difficult for the traction mechanism to be in the corresponding position, which can easily cause the traction force to decrease when the pipe is towed, and the multiple hydraulic cylinders increase the production cost of the multi-track plastic pipe traction machine; for this reason, we have designed a multi-track plastic pipe traction machine. Utility Model Content

[0004] The technical problem solved by the utility model is to provide a multi-track plastic pipe traction machine which is highly practical, can be simply operated and has a relatively simple structure. It solves the problem proposed in the above background technology that when adjusting the size of the traction pipe, multiple separate hydraulic cylinders are difficult to make the traction mechanism be in the corresponding position, which easily causes the traction force to decrease when the pipe is towed.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a multi-track plastic pipe traction machine, including a fixed cylinder and four adjustment mechanisms mounted on the surface of the fixed cylinder;

[0006] The fixed cylinder comprises a cylinder and a threaded groove on the surface of the cylinder, and a movable ring threadedly connected to the surface of the cylinder. The surface and inner wall of the cylinder are both provided with a plurality of symmetrical rectangular grooves.

[0007] The adjustment mechanism includes four fixed blocks fixedly connected to the inner wall of the cylinder, a plurality of guide rods rotatably connected on both sides of the four fixed blocks, and four H-plates parallelly mounted inside the four fixed blocks, both ends of the plurality of guide rods are arranged in a semicircular shape and teeth are arranged on the surface of one of the ends, the other ends of the plurality of guide rods are rotatably connected to both sides of the H-plate, the teeth are meshed with a tooth plate, the top of the tooth plate passes through a rectangular groove and is fixedly connected to a connecting block, the surface of the connecting block is fixedly connected to a slider, and one end of the slider is slidably connected to one end of a movable ring.

[0008] Optionally, two guide wheels are rotatably connected to the empty grooves on both sides of the four H-plates, and tracks are sleeved on the surfaces of the guide wheels.

[0009] Optionally, both ends of the guide wheel pass through the H-plate, four servo motors are fixedly mounted on the surfaces of the four H-plates, and the output ends of the servo motors are fixedly connected to the guide wheel.

[0010] Optionally, both ends of the cylinder are fixedly connected with fixing rings, and the surface of the fixing ring is fixedly connected with a bracket.

[0011] Optionally, a rubber ring is fixedly connected to the surface of the movable ring, and the surface of the rubber ring is provided with concave-convex patterns.

[0012] The utility model provides a multi-track plastic pipe traction machine, which has the following beneficial effects:

[0013] The multi-track plastic pipe traction machine uses an adjustment mechanism. When it is necessary to adjust the device to traction pipes of different sizes, the movable ring is rotated to rotate on the surface of the cylinder, and then the slider slides on one end, and at the same time drives the slider to move horizontally, so that the tooth plate drives the teeth to move, so that one end of the guide rod rotates on both sides of the fixed block, and the other end drives the H plate to move. The rotation can be stopped when it is adjusted to a suitable position, which can control multiple H plates to be in corresponding positions, reduce the situation where multiple H plates are not in corresponding positions during adjustment, improve the traction force of the device on the pipe after adjustment, and can complete the adjustment of the size of the traction pipe of the device without a hydraulic cylinder, thereby reducing the production cost of the device.
