Description

Technical Field

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

[0002] In water conservancy project construction, pipeline laying and connection are crucial links. With the continuous expansion of the scale of water conservancy projects and the increasing requirements for construction quality, efficient and precise pipeline connection has become the key to ensuring the stable operation of the water conservancy system. Pipeline roller frames, as commonly used equipment to assist in pipeline laying and connection, play an important role.

[0003] Currently, common pipe roller frames on the market mainly consist of a support frame and rollers mounted on the support frame. During actual water conservancy construction, factors such as uneven ground, uneven traction speed, and strong winds can cause lateral displacement of the pipe on the rollers. Even slight lateral displacement can lead to misalignment at pipe joints, affecting welding or connection quality and ultimately reducing the overall sealing of the water conservancy pipeline system. Therefore, we propose a pipe jointing auxiliary device for water conservancy construction to address these problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a pipeline docking auxiliary device for water conservancy construction.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pipe docking auxiliary device for water conservancy construction includes a support frame, pipe supports symmetrically distributed on the inner side of the support frame, two sets of U-shaped blocks fitted at the bottom end of the support frame, and a limiting plate distributed on the top of the U-shaped blocks. A vertical rod is inserted at the center of the U-shaped blocks, and a connecting plate is fixedly connected to the top of the vertical rod. The support frame has equidistant limiting grooves that match the vertical rods at transverse intervals inside. A slider is fixedly connected to the inner side of the U-shaped blocks, and a sliding groove that matches the slider is opened on the outer wall of the support frame.

[0007] Preferably, the bottom end of the limiting plate is symmetrically connected with a mating plate, and the side of the mating plate that is close to each other abuts against the outer surface of the U-shaped block. Threaded rods are inserted into the interior of the mating plates, and rotating blocks are fixedly connected to the ends of the threaded rods. The interior of the U-shaped block has a slot that matches the threaded rod.

[0008] Preferably, the top of the U-shaped block has a groove, and the inner wall of the groove is vertically connected to a spring, the other end of the spring being fixedly connected to the connecting plate.

[0009] Preferably, the outer surface of the threaded rod is provided with external threads, and the inner wall of the slot is provided with internal threads.

[0010] Preferably, the inner wall of the limiting plate is fixedly connected to a support plate, and rollers are equidistantly connected to the sides of the support plates that are close to each other.

[0011] Preferably, there are two sets of sliders and grooves, and the two sets of sliders and grooves are symmetrically distributed about the central axis of the U-shaped block.

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

[0013] 1. This device, equipped with a U-shaped block and a limiting plate, can laterally limit the pipe placed above the pipe support during use by working together with the U-shaped block and the limiting plate. This effectively prevents the pipe from easily shifting, thus ensuring accurate pipe connection and guaranteeing the precision of pipe connection.

[0014] 2. The device is equipped with a support plate and rollers. During use, the cooperation between the support plate and rollers can prevent the inner wall of the limiting plate from directly contacting the pipe, and convert sliding friction into rolling friction, thereby reducing the resistance during pipe traction and preventing wear on the outer wall of the pipe.

[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] Reference Figure 1-5 A pipe-connection auxiliary device for water conservancy construction includes a support frame 1, pipe supports 2 symmetrically distributed on the inner side of the support frame 1, two sets of U-shaped blocks 3 fitted at the bottom end of the support frame 1, and a limiting plate 4 distributed on the top of the U-shaped blocks 3. A vertical rod 6 is inserted at the center of the U-shaped blocks 3, and a connecting plate 5 is fixedly connected to the top of the vertical rod 6. Limiting grooves adapted to the vertical rod 6 are equidistantly opened laterally inside the support frame 1. A slider 11 is fixedly connected to the inner side of the U-shaped blocks 3. A sliding groove 12 adapted to the slider 11 is opened on the outer wall of the support frame 1. A rectangular groove is opened at the bottom end of the limiting plate 4 to allow the limiting plate 4 to move normally left and right. The movable support frame 1 consists of a set of crossbars, two sets of symmetrically distributed support frames, and a set of trapezoidal blocks in the middle. The trapezoidal blocks and crossbars are fixedly connected together, and the bottom ends of the two sets of support frames are also fixedly connected to the ends of the crossbars. The crossbars are equipped with scale marks, which are not shown in the figure. The scale marks facilitate the precise lateral movement of the limiting plate 4 by the operator. The U-shaped block 3 is limited by the cooperation of the slider 11 and the slide groove 12, which effectively prevents the U-shaped block 3 from moving up and down, thereby further ensuring the stable movement of the U-shaped block 3 and the limiting plate 4.

[0023] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the bottom end of the limiting plate 4 is symmetrically connected with the mating plate 8, and the side of the mating plate 8 that is close to each other abuts against the outer surface of the U-shaped block 3. The mating plate 8 is respectively inserted with threaded rods 9, and the end of the threaded rod 9 is fixedly connected with a rotating block 10. The U-shaped block 3 has a slot that matches the threaded rod 9. During use, the installation and removal of the limiting plate 4 and the U-shaped block 3 can be realized through the cooperation of the threaded rod 9, the rotating block 10 and the slot, so that the staff can quickly replace the damaged limiting plate 4.

[0024] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the top of the U-shaped block 3 has a groove, and the inner wall of the groove is vertically connected to a spring 7. The other end of the spring 7 is fixedly connected to the connecting plate 5. During use, the cooperation between the groove and the spring 7 can effectively ensure the tightness of the vertical rod 6 when it is inserted into the internal limiting groove of the support frame 1.

[0025] Furthermore, refer to Figure 3 and Figure 4It can be seen that the outer surface of the threaded rod 9 is provided with external threads, and the inner wall of the slot is provided with internal threads. The internal and external threads are not shown in the figure. Through the threaded engagement of the threaded rod 9 and the U-shaped block 3, the tightness of the connection between the U-shaped block 3 and the mating plate 8 can be ensured.

[0026] Furthermore, refer to Figure 1 and Figure 2 It can be seen that the inner wall of the limiting plate 4 is fixedly connected to the support plate 13, and the support plates 13 are equidistantly connected to the side of each other. By setting multiple sets of rollers 14, the pipe can be guided and limited to reduce the resistance when the pipe moves.

[0027] Furthermore, refer to Figure 2 It can be seen that there are two sets of sliders 11 and slide grooves 12, and the two sets of sliders 11 and slide grooves 12 are symmetrically distributed about the central axis of the U-shaped block 3. During use, the reliability of the U-shaped block 3 and the limiting plate 4 when moving laterally can be effectively guaranteed by the cooperation of sliders 11 and slide grooves 12.

[0028] Working Principle: When using this utility model, the operator can first place the device in a suitable position, and then, according to the outer diameter of the pipe, lift the connecting plate 5 to simultaneously force the vertical rod 6 connected to its bottom end, thereby pulling the vertical rod 6 out of the limiting groove opened inside the support frame 1. Then, the operator can push the U-shaped block 3 laterally to adjust the lateral position of the U-shaped block 3. After the adjustment is completed, the operator can stop pulling the connecting plate 5, so that the vertical rod 6 is forcefully embedded into the corresponding limiting groove at the bottom end of the support frame 1, thereby limiting the limiting plate 4. After the distance between the two sets of limiting plates 4 is adjusted, the operator can place the pipe to be connected on the two sets of pipe supports 2 to support the pipe, thereby meeting the subsequent normal connection between the pipes. During the entire connection process, the limitation of the two sets of limiting plates 4 can prevent the pipe from moving laterally, thus ensuring the stable connection of the pipe. The above is the complete working principle of this utility model.
