Description

Technical Field

[0001] This utility model belongs to the field of ductile iron pipe connection technology, specifically relating to a wheel-sliding push mechanism for sliding connection of ductile iron pipes. Background Technology

[0002] Ductile iron pipes are a commonly used piping material, widely applied in water supply, drainage, and gas supply. During the installation of ductile iron pipe connections, the common connection methods include welding and flange connections. Regardless of the method, sliding-in connection rollers are required for pipe joining. Slide-in connection rollers are widely used due to their ease of installation and robust connection.

[0003] However, during the installation of ductile iron pipes, the movement and adjustment of the pipes often require significant manpower and resources, which is time-consuming, labor-intensive, and prone to damaging the pipes. Currently, the slide-in connection of ductile iron pipes typically relies on manual handling and adjustment, using simple sliding or rolling devices to assist in the movement of the pipes. These devices include simple rollers, sliding plates, etc., which reduce the friction during pipe movement to some extent. However, the rolling or sliding devices in existing technologies often have poor stability, easily causing the pipes to tilt or overturn during movement, affecting the installation quality. High friction results in a large amount of manpower required to move the pipes, leading to low work efficiency. It is difficult to accurately adjust the conveying direction and height of the pipes using existing technologies, affecting the connection quality. Safety accidents such as falls and collisions are prone to occur during manual handling and adjustment.

[0004] In view of this, we propose a sliding drive mechanism for ductile iron pipe sliding connection to solve the above problems. Utility Model Content

[0005] The present invention aims to solve the technical problem that in the prior art, the sliding-in connection of the pulley is difficult to achieve precise horizontal and vertical adjustment, and the only auxiliary pushing is by the roller, which results in large friction and high energy consumption when moving the iron pipe.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A sliding drive mechanism for ductile iron pipe sliding connection includes universal balls and threaded rods for sliding and translating or rolling with the iron pipe. The universal balls are provided in a plurality of evenly distributed installations on the top arc plate of the arc-shaped mounting box. The two arc-shaped cover plates at the bottom of the arc-shaped mounting box are connected by a latch.

[0008] The bottom end of the threaded rod is threaded into a support with an internal thread groove, and the top end is inserted into the sleeve at the bottom of the rotating seat. The arc-shaped mounting box is supported by the rotating seat.

[0009] The rotation of the sleeve relative to the threaded rod drives the rotating seat and the arc-shaped mounting box to adjust the horizontal direction, thereby adjusting the conveying direction of the iron pipe;

[0010] The threaded rod is adjusted by rotating it relative to the support, thereby adjusting the height of the rotating seat and the arc-shaped mounting box, and adjusting the conveying height of the iron pipe.

[0011] Preferably, one end of each of the two arc-shaped cover plates is rotatably connected to the arc-shaped mounting box via a pivot. By opening the latch, the two arc-shaped cover plates are opened, thereby exposing the internal cavity of the arc-shaped mounting box for maintenance or replacement of the universal ball joint.

[0012] When the ball joint needs repair or replacement, simply unlock the latches to easily open the two curved covers, revealing the internal chamber of the curved mounting box. This greatly simplifies the maintenance process and reduces its difficulty.

[0013] Preferably, the rotating base includes two vertical support plates connected to the left and right ends of the arc-shaped mounting box, a rectangular frame plate fixed to the bottom of the two vertical support plates, a central partition plate fixed at the center of the rectangular frame plate, and two reinforcing panels fixed to both sides of the rectangular frame plate. A sleeve is fixed at the center of the bottom of the central partition plate. The combined structure of the two vertical support plates, the rectangular frame plate, the central partition plate, and the reinforcing panels provides a robust and stable support for the rotating base, ensuring the stability of the mechanism during operation.

[0014] Preferably, the sleeve is connected to the middle partition and the reinforcing panel by several reinforcing ribs A.

[0015] The addition of reinforcing rib A improves the connection strength between the sleeve and the middle partition and the reinforcing panel, making the overall structure more robust and able to withstand greater workloads.

[0016] Preferably, the sleeve is threadedly connected to a locking knob A that locks the threaded rod inside the sleeve. The threaded connection of the locking knob A ensures that the rotating seat is fixed in position after horizontal adjustment.

[0017] Preferably, the support is fixed at the center of the top of the square plate, and a square frame plate is provided around the perimeter of the square plate. The support is connected to the square plate and the square frame plate by several reinforcing ribs B. The reinforcing ribs B connect the support, the square plate, and the square frame plate, forming a more stable overall structure.

[0018] Preferably, the support is threadedly connected to a locking knob B that secures the threaded rod within the support. The threaded connection of the locking knob B provides a robust locking mechanism that ensures the threaded rod will not loosen within the support.

[0019] Compared with the prior art, the technical effects and advantages of this utility model are:

[0020] This ductile iron pipe sliding connection wheel-driven mechanism achieves precise adjustment and movement of the iron pipe through a precisely designed mechanical structure. The universal balls within the mechanism are evenly distributed on the arc-shaped plate at the top of the arc-shaped mounting box, providing stable support and rolling during pipe movement, reducing frictional damage. The threaded connection between the threaded rod and the support, along with the rotating mechanism of the sleeve, allows for fine-tuning in both horizontal and vertical directions, thus enabling precise control over the direction and height of the iron pipe transport.

[0021] The design of this sliding-in connection mechanism for ductile iron pipes significantly reduces labor intensity and improves work efficiency during pipe installation. Because the rolling friction of the universal ball joint is less than the sliding friction, the mechanism significantly reduces energy consumption when moving the pipe, while also preventing damage caused by improper movement. Furthermore, the precise adjustment function ensures high accuracy during pipe connection, thereby improving the connection quality.

[0022] The design of the ductile iron pipe sliding connection wheel drive mechanism also considers ease of maintenance. Two arched covers at the bottom of the arc-shaped mounting box are connected by a locking mechanism, making the maintenance or replacement of the swivel ball extremely simple. Simply open the locking mechanism to easily open the arched covers, exposing the internal chamber for convenient maintenance of the swivel ball. This design not only reduces maintenance difficulty but also shortens the time required for maintenance, further improving overall work efficiency and user experience. Attached Figure Description

[0029] 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.

[0030] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0031] This application discloses a sliding drive mechanism for a ductile iron pipe sliding connection, including a universal ball 1 and a threaded rod 5 for sliding or rolling with the iron pipe. Several universal balls 1 are evenly distributed and installed on the top arc-shaped plate 3 of an arc-shaped mounting box 2. Two arc-shaped cover plates 4 at the bottom of the arc-shaped mounting box 2 are connected by a latch 16. One end of each arc-shaped cover plate 4 is rotatably connected to the arc-shaped mounting box 2 via a pivot. By opening the latch 16, the two arc-shaped cover plates 4 are opened, exposing the internal cavity 9 of the arc-shaped mounting box 2 for maintenance or replacement of the universal balls 1. When maintenance or replacement of the universal balls 1 is required, simply opening the latch 16 easily opens the two arc-shaped cover plates 4, exposing the internal cavity 9 of the arc-shaped mounting box 2. This greatly simplifies the maintenance process and reduces maintenance difficulty. The quick opening and closing of the arc-shaped cover plates 4 reduces maintenance time and improves work efficiency. When in use, the internal chamber 9 can be completely sealed to prevent personnel from accidentally coming into contact with the internal parts during operation, thus improving safety.

[0032] The bottom end of the threaded rod 5 is threadedly connected to the support 15 with an internal thread groove 6, and the top end is inserted into the sleeve 8 at the bottom of the rotating seat 7. The arc-shaped mounting box 2 is supported by the rotating seat 7. The rotation of the sleeve 8 relative to the threaded rod 5 drives the rotating seat 7 and the arc-shaped mounting box 2 to adjust the horizontal direction, thereby adjusting the conveying direction of the iron pipe.

[0033] The rotating base 7 includes two vertical support plates 71 connected to the left and right ends of the arc-shaped mounting box 2, a rectangular frame plate 72 fixed to the bottom of the two vertical support plates 71, a central partition plate 73 fixed at the center of the rectangular frame plate 72, and two reinforcing panels 75 fixed to both sides of the rectangular frame plate 72. A sleeve 8 is fixed at the center of the bottom of the central partition plate 73. The combined structure of the two vertical support plates 71, the rectangular frame plate 72, the central partition plate 73, and the reinforcing panels 75 provides a robust and stable support for the rotating base 7, ensuring the stability of the mechanism during operation. The design of the rectangular frame plate 72 and the reinforcing panels 75 helps to distribute the load applied to the rotating base 7, extending the service life of the mechanism. The central position of the central partition plate 73 provides sufficient operating space between the sleeve 8 and the rectangular frame plate 72 for the maintenance and replacement of the universal ball joint 1, improving the convenience of assembly and maintenance.

[0034] The sleeve 8 is connected to the middle partition 73 and the reinforcing panel 75 by several reinforcing ribs A74. The addition of reinforcing ribs A74 improves the connection strength between the sleeve 8 and the middle partition 73 and the reinforcing panel 75, making the overall structure more robust and able to withstand greater working loads. When subjected to external forces, the reinforcing ribs A74 help prevent deformation of the sleeve 8 and adjacent components, ensuring the accuracy and stability of the mechanism during operation.

[0035] A locking knob A10 is threadedly connected to the sleeve 8 to lock the threaded rod 5 securely within the sleeve 8. The threaded connection of the locking knob A10 ensures that the rotating seat 7 is properly positioned after horizontal adjustment, and that the threaded rod 5 is firmly fixed within the sleeve 8, preventing the rotating seat 7 from loosening during use. The design of the locking knob A10 allows for more precise locking and adjustment of the threaded rod 5, facilitating accurate control of the positions of the rotating seat 7 and the arc-shaped mounting box 2, thereby improving the overall performance of the mechanism.

[0036] The threaded rod 5 is adjusted by rotating it relative to the support 15, thereby adjusting the height of the rotating seat 7 and the arc-shaped mounting box 2, and adjusting the conveying height of the iron pipe.

[0037] The support 15 is fixed at the top center of the square plate 11. The square plate 11 is surrounded by a square frame plate 12. The support 15 is connected to the square plate 11 and the square frame plate 12 by a number of reinforcing ribs B13.

[0038] Reinforcing rib B13 connects the support 15, square plate 11, and square frame plate 12, forming a more stable overall structure. This effectively distributes and bears the force generated by the rotation of the threaded rod 5, increasing the torsional and compressive resistance of the entire mechanism. The presence of reinforcing rib B13 helps reduce structural deformation caused by vibration during operation, ensuring the accuracy and reliability of the mechanism. By increasing the stability of the connection, fatigue damage caused by prolonged use or repetitive operation is reduced, extending the service life of the entire mechanism.

[0039] A locking knob B14 is threadedly connected to the support 15 to secure the threaded rod 5 within the support 15. The threaded connection of the locking knob B14 provides a robust locking mechanism, ensuring that the threaded rod 5 will not loosen within the support 15, thus guaranteeing the stability and safety of the mechanism. The design of the locking knob B14 allows the operator to easily adjust the position of the threaded rod 5 and quickly secure it once the desired position is reached, improving work efficiency. The addition of the locking knob B14 prevents the threaded rod 5 from loosening due to misoperation or external vibration, ensuring that the normal operation of the mechanism is not disturbed. When maintenance or replacement of the threaded rod 5 is required, the quick-unlocking function of the locking knob B14 simplifies the operation, making maintenance work more convenient.

[0040] In use, the ductile iron pipe is placed on the arc-shaped mounting box 2, and the universal balls 1 are evenly distributed on the arc plate at the top of the arc-shaped mounting box 2. They can rotate freely, so that the iron pipe can maintain balance when sliding or rolling, reducing friction and damage caused by the movement of the iron pipe.

[0041] The evenly distributed omnidirectional balls 1 provide stable support for the iron pipe, preventing it from tilting or tipping over during movement. The rolling friction of the omnidirectional balls 1 is less than the sliding friction, thus reducing the frictional force during pipe movement and lowering energy consumption. The omnidirectional balls 1 can adapt to the shape of the curved mounting box 2, making the iron pipe move more smoothly along the curved path.

[0042] The bottom end of the threaded rod 5 mates with the internal threaded groove 6 of the support 15. By rotating the threaded rod 5, its lifting and lowering motion can be achieved, thereby adjusting the height of the rotating seat 7 and the arc-shaped mounting box 2, and thus adjusting the conveying height of the iron pipe. The rotation of the sleeve 8 relative to the threaded rod 5 drives the rotating seat 7 and the arc-shaped mounting box 2 to adjust the overall horizontal direction, thereby adjusting the conveying direction of the iron pipe.

[0043] By precisely adjusting the height and orientation of the rotating seat 7 and the arc-shaped mounting box 2, the accuracy of the two iron pipes during connection can be ensured, improving the connection quality. Mechanical adjustment of the iron pipe position reduces the labor intensity of manual handling and adjustment, improving work efficiency. It also avoids potential safety accidents during manual operation, such as falls and collisions. This roller-sliding propulsion mechanism can adapt to ductile iron pipes of different specifications and lengths, exhibiting strong versatility and flexibility.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
