Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe processing and conveying technology, and in particular to a pipe conveying device for corrugated pipe processing. Background Technology

[0002] After the corrugated pipe is formed, it already has the appearance of a finished product. In order to facilitate subsequent processing, a conveying device is used to transfer the corrugated pipe between different work stations. Most existing conveying devices consist of a supporting frame and a rotating wheel on the top of the frame. The rotating wheel lifts and assists the corrugated pipe in moving.

[0003] The corrugated pipe has an uneven, relatively regular surface. When it moves across the surface of the rotating wheel, these uneven areas cause the corrugated pipe to vibrate. This vibration acts on the entire corrugated pipe, and since the rest of the pipe is also in contact with the rotating wheel, this vibration directly affects the stability of the corrugated pipe during transport and may even cause it to deviate from its path, posing a certain safety hazard. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a pipe conveying device for corrugated pipe processing, which solves the problem that the corrugated pipe is unstable during movement due to vibration, and may even deviate from its path.

[0005] The technical solution of this utility model is as follows: a pipe conveying device for corrugated pipe processing, including a lifting frame, guide wheels are spaced apart on the top of the lifting frame, a gantry frame is provided on the top of the lifting frame, a number of swing arms are hinged to the top of the gantry frame, rubber wheels are hinged to the ends of the swing arms, and a torsion assembly is provided on the top of the gantry frame. When the swing arms swing up, the torsion assembly applies downward pressure to the swing arms to push the swing arms.

[0006] Furthermore, the torsion assembly includes an arc-shaped groove formed on the top of the gantry support. The arc-shaped groove is concentrically arranged with the rotation path of the swing arm. A spring is installed inside the arc-shaped groove, and the end of the spring abuts against a push rod. The push rod spans the gantry and is parallel to the top of the gantry. The movement path of the push rod can be restricted by the arc-shaped groove. At the same time, the spring applies a thrust to keep the push rod always located at one end of the arc-shaped groove, so that the swing arm can contact the push rod and receive a thrust when it is raised.

[0007] Furthermore, the push rod of the torsion assembly contacts the swing arm when the swing arm is raised to 70° and applies downward pressure to the swing arm. The swing arm hangs down naturally when it is not raised. When the swing arm contacts the moving pipe, it can be pushed up by the pipe. After being raised, it is restricted by the push rod to generate downward pressure, so as to prevent the push rod from blocking the normal movement of the pipe.

[0008] Furthermore, a limiting rod for the through spring and push rod is provided inside the arc-shaped groove. The limiting rod is a curved rod adapted to the curvature of the arc-shaped groove. The limiting rod restricts the position of the spring and the movement of the push rod.

[0009] Furthermore, the swing arm consists of a sheet-like vertical plate and an arc-shaped curved rod connected to a rubber wheel at the end of the vertical plate. The vertical plates of several swing arms are torsionalally adapted to the pipe, so that the rubber wheel at the end of the swing arm fits against the outer wall of the pipe, ensuring that the rubber wheel can effectively contact the pipe.

[0010] Furthermore, the rubber wheel is a hollow inflatable wheel, and the rubber wheel is not fully inflated. When the rubber wheel is subjected to pressure, it can deform and make better contact with the pipe.

[0011] Furthermore, the torsion assembly is a torsion shaft connecting the swing arm and the gantry. The torsion shaft can always drive the swing arm to rotate towards the lifting frame, so that the swing arm can generate sufficient downward pressure on the pipeline without being fully lifted.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model restricts the movement path of the pipeline by setting a gantry frame at the top of the support frame, and sets a swing arm at the top of the gantry frame. When the pipeline passes by, the swing arm is pushed until the swing arm is at the top of the pipeline. At this time, the top side of the pipeline is guided by the rubber wheel at the end of the swing arm, and the bottom contacts the guide wheel, making the movement of the pipeline more stable and less likely to fall outward.

[0014] 2. This utility model provides a torsion assembly at the top of the gantry frame. The torsion assembly generates downward pressure on the swing arm. When the swing arm is at the top of the pipe, it presses down on the pipe, and the pipe reduces vibration under the action of the downward pressure. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, such as Figure 1-4 As shown, a pipe conveying device for corrugated pipe processing includes a lifting frame 1, with guide wheels 2 spaced apart on the top of the lifting frame 1, a gantry frame 3 on the top of the lifting frame 1, and several swing arms 4 hinged to the top of the gantry frame 3. Rubber wheels 5 are hinged to the ends of the swing arms 4. Each swing arm 4 consists of a sheet-like vertical plate and an arc-shaped curved rod connected to the end of the vertical plate. The vertical plates of the several swing arms 4 are torsionalally adapted to the pipe, so that the rubber wheels 5 at the ends of the swing arms 4 fit against the outer wall of the pipe, ensuring that the rubber wheels 5 can effectively contact the pipe. The rubber wheels 5 are hollow inflatable rotating wheels. The rubber wheels 5 are in a partially inflated state. When the rubber wheels 5 are subjected to pressure, they can deform to better contact the pipe.

[0023] A torsion assembly 6 is provided on the top of the gantry frame 3. When the swing arm 4 is swung up, the torsion assembly 6 applies downward pressure to push the swing arm 4. The torsion assembly 6 includes an arc-shaped groove 61 opened on the top of the gantry frame 3 support. The arc-shaped groove 61 is concentric with the rotation path of the swing arm 4. A spring 62 is provided inside the arc-shaped groove 61. The end of the spring 62 abuts against the push rod 63. The push rod 63 spans the gantry frame 3 and is parallel to the top of the gantry frame 3. The movement path of the push rod 63 can be restricted by the arc-shaped groove 61. At the same time, the spring 62 applies a thrust to keep the push rod 63 always located at one end of the arc-shaped groove 61 so that the swing arm 4 can contact the push rod 63 and receive the thrust when it is lifted.

[0024] The arc-shaped groove 61 is equipped with a limiting rod 64 that passes through the spring 62 and push rod 63. The limiting rod 64 is a curved rod that is adapted to the curvature of the arc-shaped groove 61. The limiting rod 64 restricts the position of the spring 62 and the movement of the push rod 63. When the push rod 63 of the torsion assembly 6 is raised to 70°, it contacts the swing arm 4 and applies downward pressure to the swing arm 4. The swing arm 4 hangs down naturally when it is not raised. When the swing arm 4 comes into contact with the moving pipe, it can be pushed up by the pipe. After being raised, it is restricted by the push rod 63 to generate downward pressure, so as to prevent the push rod 63 from blocking the normal movement of the pipe.

[0025] The working principle of this utility model is as follows: First, the pipeline moves towards the gantry 3 under the action of the guide wheel 2 at the top of the lifting frame 1. During the movement, the end of the pipeline passes through the gantry 3, pushing the swing arm 4 to lift. When the swing arm 4 is lifted to 70°, it contacts the push rod 63 and pushes the push rod 63. The push rod 63 moves along the limiting rod 64 and compresses the spring 62. The spring 62 is compressed and pushes the push rod 63 in the opposite direction, causing the push rod 63 to press the swing arm 4. During this process, the swing arm 4 is completely located at the top of the pipeline, with only the rubber wheel 5 at the end in contact with the pipeline. The rubber wheel 5 presses down on the pipeline under the push of the swing arm 4, making the pipeline move stably. When the pipeline vibrates, the rubber wheel 5 presses down on the pipeline to reduce the vibration.

[0026] Example 2, as Figure 5 As shown, the difference from Embodiment 1 is that the torsion component 6 is a torsion shaft connecting the swing arm 4 and the gantry 3. The torsion shaft can always drive the swing arm 4 to rotate towards the lifting frame 1, so that the swing arm 4 does not need to be fully lifted to generate sufficient downward pressure on the pipe. Even if the pipe diameter is reduced to the point that it is not enough to lift the swing arm 4, the swing arm 4 can still generate sufficient downward pressure to press the pipe down, so that the pipe moves forward stably during the movement.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
