Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering, and in particular to a water conservancy pipeline connection device for water conservancy projects. Background Technology

[0002] Water conservancy pipelines are typically large in diameter and buried in underground pits. Pipeline connections are usually either threaded or flanged. Threaded connections result in a smoother surface with fewer protrusions, but when the diameter exceeds 1 meter, rotation is difficult, making installation time-consuming and labor-intensive. Flange connections eliminate the need for rotation during installation; simply aligning the pipe simplifies the process considerably. However, the flange creates protrusions on the pipe surface and increases the overall cost.

[0003] The prior art (CN222732284U) discloses a water conservancy pipeline connection device, which uses two clamping clamps to fix the pipeline to facilitate the connection between pipelines. However, this structure is not suitable for pipelines with a diameter of more than 1 meter, and the connected pipeline is at a high height above the ground. After the connection device is removed, the drop of the pipeline to the ground is large, which can easily cause the pipeline joint to break. Utility Model Content

[0004] The purpose of this application is to provide a water conservancy pipeline connection device for water conservancy projects, which aims to solve the problems existing in the prior art.

[0005] This application provides a water conservancy engineering water pipeline connection device, including a vehicle platform. The bottom of the vehicle platform is equipped with wheels that roll in the front-to-back direction. Vehicle walls are fixed on both the left and right sides of the vehicle platform, and handrails are fixed on the vehicle walls. Two guide rollers are rotatably connected to the vehicle platform. The two guide rollers are distributed left and right and are parallel to each other. The guide rollers extend in the front-to-back direction and are spaced apart. The pipe to be connected is placed on both guide rollers. The roller shafts of the two guide rollers are synchronously connected and connected to a drive device that drives the guide rollers to rotate.

[0006] Two guide rollers are fixed to the car plate by a base plate, and an arc-shaped groove is opened on the base plate corresponding to each guide roller.

[0007] The driving device is a geared motor or a crank.

[0008] The handrails are fixedly connected to the top of the vehicle wall. The two handrails are curved outwards from the vertical line, and the ends of the handrails are rod-shaped.

[0009] The wheels include shallow wheels located on the left and right sides of the vehicle body and deep wheels near the center line of the vehicle body, with the bottom of the deep wheels being lower than the bottom of the shallow wheels.

[0010] The diameter of the guide roller is smaller than the diameter of the pipe to be connected.

[0011] The beneficial effects of this utility model are: it is applicable to the connection of large-diameter water conservancy pipelines and is suitable for threaded connection structures, making the connection process simple and easy. Compared with the prior art, the height of the platform and guide rollers are close to the ground, so that the pipeline is connected close to the ground, reducing the height difference between the pipeline to be connected and the already connected pipeline, thereby reducing the possibility of breakage at the pipeline joint.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1 The diagram illustrates a water conservancy pipeline connection device for a water conservancy project. It includes a platform 1 with wheels mounted on its bottom for forward and backward movement. Walls 2 are fixed to both sides of the platform 1, and handles 3 are fixed to the walls 2 for manually pulling the platform 1. A base plate 4 is fixedly connected to the platform 1, and mounting seats 5 are fixed to both the front and rear ends of the base plate 4. Guide rollers 6 are rotatably connected to the mounting seats 5. There are two guide rollers 6, arranged horizontally and parallel to each other, extending in the forward and backward direction with a gap between them. A pipe 7 to be connected is placed on both guide rollers 6. The diameter of the guide rollers 6 is smaller than the diameter of the pipe 7 to be connected. The pipe 7 and the two guide rollers 6 are arranged in a triangular shape. Figure 2 As shown, when the two guide rollers 6 rotate, they can drive the pipe 7 to be connected to rotate through friction.

[0019] The rollers of the two guide rollers 6 are synchronously connected via a transmission belt or chain, and are connected to a drive device that drives the guide rollers 6 to rotate. The drive device is a geared motor or a crank 8. In this embodiment, the crank 8 is used as an example. The crank 8 is connected to one guide roller 6. Rotating the crank 8 can drive the guide roller 6 to rotate. Since the two guide rollers 6 are synchronously connected, the transmission belt or chain can make one guide roller 6 rotate, thereby driving the other guide roller 6 to rotate synchronously in the same direction, thus driving the pipe 7 to be connected to rotate in one direction.

[0020] An arc-shaped groove 9 is provided on the base plate 4 for each guide roller 6. The arc-shaped groove 9 can appropriately reduce the height of the guide roller 6, so that the height of the pipe to be connected 7 is close to the height of the already connected pipe when connecting.

[0021] In this embodiment, the handrail 3 is fixedly connected to the top of the vehicle wall 2. The two handrails 3 are in the shape of an arc that curves outward from the vertical line. The ends of the handrails 3 are rod-shaped so as to facilitate manual gripping.

[0022] In this embodiment, the wheels include shallow wheels 10 located on the left and right sides of the vehicle platform 1 and deep wheels 11 near the center line of the vehicle platform 1. The number of deep wheels 11 and shallow wheels 10 is not limited. To maintain the stability of the vehicle platform 1, shallow wheels 10 are installed at the front, middle, and rear of the vehicle platform 1, while deep wheels 11 are installed at the front and rear of the vehicle platform 1. The bottom of the deep wheels 11 is lower than the bottom of the shallow wheels 10 to match the shape of the circular pit bottom, which is deep at the center and shallow on the sides. When the bottom of the pit for burying the water pipeline is flat, only one type of wheel can be used.

[0023] Usage instructions are as follows: Figure 3 As shown, place the cart 1 in the pit along its length, with the end with the crank 8 as the front end, facing forward of the pit and the rear end facing backward and towards the already connected pipe. Position the threaded section of the pipe 7 to be connected towards the rear end of the cart, extending it beyond the cart 1. Workers push the cart 1 backward from both sides, bringing the pipe 7 closer to and inserting it into the already connected pipe. Then, rotate the crank 8, causing the guide roller 6 to rotate the pipe 7, connecting it to the already connected pipe via threaded engagement. Workers can continue to push the pipe 7 backward during this process, thus completing the connection of one section of pipe 7. Afterward, slightly lift the pipe to separate it from the guide roller 6, allowing the worker to push the cart 1 out from under the pipe.

[0024] The above embodiments are not intended to limit the present invention. Unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or a connection within two components.
