Description

Technical Field

[0001] This utility model relates to the field of municipal engineering equipment technology, and in particular to an adjustable municipal water supply pipeline connection device. Background Technology

[0002] Municipal engineering refers to the construction and maintenance of basic public infrastructure necessary for the survival and development of a city. It mainly serves the normal operation of the city and the living needs of residents, and is an important support for urban development. Municipal engineering has the characteristics of public welfare, basic nature and system. It is usually planned, invested and constructed by the government, and is directly related to the improvement of urban functions and the quality of life of residents.

[0003] In the construction of municipal water supply projects, the quality of the pipeline connection process directly determines the sealing and durability of the pipeline system. In current engineering practice, traditional pipeline connection devices have certain technical bottlenecks, such as limited mechanical adjustment range, which makes it difficult to adapt to the construction needs of different pipe diameters. This results in the need to equip the site with multiple sets of special equipment. At the same time, there is a lack of effective pipeline positioning auxiliary functions. During construction, it is still necessary to rely on hoisting equipment and manual adjustment, which greatly increases the labor intensity and seriously restricts the construction efficiency and quality control level of municipal water supply projects.

[0004] Therefore, it is necessary to design an adjustable municipal water supply pipeline connection device. Utility Model Content

[0005] To overcome the shortcomings of traditional pipe connection devices, such as difficulty in flexibly adapting to pipes of different diameters, the need for a large amount of manpower during construction, and reduced construction efficiency, this utility model provides an adjustable municipal water supply pipe connection device.

[0006] The technical solution is: an adjustable municipal water supply pipeline connection device, comprising a base plate, movable wheels, fixed seats, lower clamping blocks, guide rods, handwheels, a movable frame, upper clamping blocks, a first screw, a limit rod, a second screw, a motor, a pinion, a rotating drum, and a large gear. Multiple movable wheels are rotatably connected to the bottom of the base plate. A fixed seat is fixedly connected to the top right end of the base plate, and a fixed seat is also slidably connected to the top left end of the base plate. Lower clamping blocks are fixedly connected to the top of each fixed seat. Two guide rods are fixedly connected to the rear side of the top of each fixed seat. A movable frame is slidably connected between the two guide rods. Upper clamping blocks are fixedly connected to the front side of each movable frame. Each base is rotatably connected to a first screw, and each movable frame is threadedly connected to the corresponding first screw. Each first screw is fixedly connected to a handwheel. A rotating drum is rotatably connected inside the right-end fixed base, and a large gear is fixedly connected to the outside of the rotating drum. A motor is installed on the front side of the right-end fixed base, and a small gear is connected to the output shaft of the motor. The small gear and the large gear mesh with each other. A second screw is threadedly connected inside the rotating drum. The second screw passes through the right-end fixed base and is slidably connected to it. The left side of the second screw is fixedly connected to the right side of the left-end fixed base. A limit rod is slidably connected inside the right-end fixed base, and the left side of the limit rod is fixedly connected to the right side of the left-end fixed base.

[0007] To further explain, it also includes a protective shell, which is fixedly connected to the front side of the right end mounting base and is fitted over the small gear.

[0008] To further explain, it also includes a rotating plate, which is rotatably connected to the left side of the base plate.

[0009] To further explain, it also includes retaining rings, with retaining rings rotatably connected to both the front and rear sides of the rotating plate, and the retaining rings snap into the base plate.

[0010] To further explain, it also includes ground spikes; multiple ground spikes are fixedly connected to the bottom left side of the rotating plate.

[0011] To further explain, it also includes fixed frames, rollers and conveyor belts. Multiple fixed frames are fixedly connected inside the rotating plate. Rollers are rotatably connected to both the left and right sides inside the fixed frames, and conveyor belts are connected between the rollers on both sides.

[0012] Beneficial effects: 1. The first screw is driven to rotate by the rotation of the handwheel, which drives the upper clamping block to rise and fall on the guide rod. The clamping force of the upper and lower clamping blocks can be precisely adjusted, which can not only ensure that the pipe is firmly fixed, but also avoid excessive compression that could damage the outer wall of the pipe. This solves the problem that traditional pipe docking devices are difficult to adapt to pipes of different diameters, and require a lot of manpower during construction, thus reducing construction efficiency.

[0013] 2. This utility model incorporates a motor, a small gear, a rotating drum, and a large gear. The rotation of the motor drives the rotation of the large gear via the small gear, enabling the left end fixed seat to move smoothly and at a constant speed. This prevents the pipe from shifting during transport, ensuring precise alignment of the two pipe ends and reducing errors associated with traditional manual prying and adjustment, thus improving the quality of the connection.

[0014] 3. By setting up rollers and conveyor belts, the sliding friction between the pipe and the device can be converted into rolling friction through the cooperation of the conveyor belt and rollers. This greatly reduces the resistance when pushing the pipe, and the pipe can be easily transported to the designated position without the operator expending a lot of physical strength. This greatly reduces labor intensity and improves work efficiency. Attached Figure Description

Detailed Implementation

[0022] Example: An adjustable municipal water supply pipeline connection device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the system includes a base plate 1, movable wheels 2, fixed seats 3, lower clamping blocks 4, guide rods 5, handwheels 6, movable frames 7, upper clamping blocks 8, first screws 9, limit rods 10, second screws 11, protective shells 13, motors 14, pinions 15, rotating drums 16, and large gears 17. Two movable wheels 2, symmetrically distributed, are rotatably connected to the front and rear sides of the bottom of the base plate 1. A fixed seat 3 is welded to the top right end of the base plate 1, and a fixed seat 3 is also slidably connected to the top left end of the base plate 1. Lower clamping blocks 4 are welded to the top of each fixed seat 3. Two guide rods 5 are welded to the rear side of the top of each fixed seat 3, and movable frames 7 are slidably connected between the two guide rods 5. Upper clamping blocks 8 are welded to the front side of each movable frame 7. First screws 9 are rotatably connected to the top of each fixed seat 3, and each movable frame 7 is threadedly connected to the corresponding first screw 9. Handwheels 6 are welded to the top of each first screw 9. The inside of the right-end fixed seat 3... A rotating drum 16 is rotatably connected, and a large gear 17 is welded to the outside of the rotating drum 16. A motor 14 is installed on the front side of the right end fixed seat 3, and a small gear 15 is connected to the output shaft of the motor 14. The small gear 15 meshes with the large gear 17. A protective shell 13 is welded to the front side of the right end fixed seat 3. The protective shell 13 covers the small gear 15 and protects it from external debris, preventing it from interfering with its normal operation and also preventing operators from accidentally contacting the rotating small gear 15 and getting injured. A second screw 11 is threaded inside the rotating drum 16. The second screw 11 passes through the right end fixed seat 3 and is slidably connected to it. The left side of the second screw 11 is welded to the right side of the left end fixed seat 3. A limit rod 10 is slidably connected inside the right end fixed seat 3. The left side of the limit rod 10 is welded to the right side of the left end fixed seat 3, which serves as a guide and limiter, ensuring that the left end fixed seat 3 moves smoothly and preventing deviation.

[0023] like Figure 1 , Figure 5 and Figure 6 As shown, it also includes a rotating plate 18, ground nails 19, and retaining rings 23. The rotating plate 18 is rotatably connected to the left side of the base plate 1. Two ground nails 19 are welded to the bottom left side of the rotating plate 18 and are symmetrically distributed front and back. Retaining rings 23 are rotatably connected to both the front and back sides of the rotating plate 18. The retaining rings 23 are inserted into the base plate 1, which can effectively resist the impact of external forces generated during the pipe connection process, avoid the overall shaking of the device, and improve the sealing and reliability of the pipe connection.

[0024] like Figure 1 , Figure 5 and Figure 6 As shown, it also includes a fixed frame 20, a roller 21 and a conveyor belt 22. Three fixed frames 20 are welded inside the rotating plate 18. Rollers 21 are rotatably connected to the left and right sides of the fixed frame 20. The conveyor belt 22 is connected between the rollers 21 on both sides.

[0025] In its initial state, the left-end fixed seat 3 is located on the far left of the base plate 1. When it is necessary to connect the municipal water supply pipeline, the operator first pushes the device to a suitable level ground using the movable wheel 2, and then rotates the two retaining rings 23 in sequence to disengage them from the base plate 1. At the same time, the rotating plate 18 rotates counterclockwise until the ground nail 19 is inserted into the ground, enhancing the stability of the entire device. The operator can then lift the left end of the first section of the pipeline to be connected and place it in a suitable position on the lower clamping block 4 on the right end. Next, the operator rotates the right-end handwheel 6, which drives the first screw 9 on it to rotate, causing the movable frame 7 to move downward along the corresponding guide rod 5. The upper clamping block 8 moves downwards until it is tightly pressed against the lower clamping block 4 of the first pipe and then stops rotating. Then, the right end of the second pipe section to be connected is lifted upwards, placed on the rotating plate 18, and pushed to the right. At the same time, the roller 21 rotates with the pipe, thereby driving the conveyor belt 22 to move to the right synchronously. The rolling friction of the conveyor belt 22 reduces the pushing resistance and helps to easily transport the right end of the second pipe section to be connected to a suitable position above the lower clamping block 4 on the left. Then, the left handwheel 6 is turned, and the upper clamping block 8 on the moving frame 7 moves downwards until the second pipe section is clamped and then stops rotating.

[0026] Next, start motor 14. The output shaft of motor 14 drives the small gear 15 to rotate. Since the small gear 15 and the large gear 17 mesh with each other, the large gear 17 is driven to rotate, causing the rotating drum 16 to rotate accordingly. Since the inside of the rotating drum 16 is threadedly connected to the second screw 11, the second screw 11 drives the left end fixed seat 3 to slide along the base plate 1, causing the second section of pipe to move to the right, thereby adjusting the distance between the first section of pipe and the second section of pipe, so that they gradually get closer. When the docking ends of the two pipes are aligned and reach the appropriate docking position, turn off motor 14, and the docking process can be performed.

[0027] After the connection is completed, rotate the two handwheels 6 in reverse order to loosen the clamping blocks 8 and 4, allowing the connected pipe to be pulled to the right and removed. If a third pipe section needs to be connected, pull the first two connected pipe sections to the right to move the left end of the second pipe section to a suitable position on the right lower clamping block 4. Repeat the clamping operation on the right pipe section. Then, start the motor 14 and rotate the output shaft in reverse to drive the left fixed seat 3 to slide and reset along the base plate 1 to the left. This allows the right end of the third pipe section to be lifted up and placed on the rotating plate 18 and pushed to the right. Repeat the above pipe clamping, moving, and connection operations to complete the continuous connection of multiple pipe sections. After all pipes are connected, rotate the rotating plate 18 in reverse to a horizontal position. Finally, snap the retaining ring 23 back into the base plate 1 to complete the use of this device.
