Description
Technical Field
[0001] This utility model relates to the technical field of construction equipment for water supply and drainage engineering, and in particular to a reinforcement device for the inner lining of water supply pipelines for trenchless construction. Background Technology
[0002] Municipal drainage pipe lining repair and reinforcement is a trenchless pipeline repair technology. Its core is to form a new "lining pipe" inside the existing damaged municipal drainage pipe through a specific process to repair various defects in the pipe (such as cracks, corrosion, leakage, deformation, etc.) and improve the structural strength, avoiding the damage to the road surface, traffic and surrounding environment caused by traditional excavation repair.
[0003] In urban water supply pipeline maintenance, trenchless construction technology has gradually become the mainstream method for pipeline repair due to its advantages such as not requiring large-scale road excavation and having minimal impact on traffic and the environment. However, current mainstream trenchless lining reinforcement technologies still have significant limitations: existing devices mostly rely on a single airbag for pressurization, which can easily lead to gap differences between the lining pipe and the original pipeline due to uneven pressure distribution. This not only affects the pipeline's cross-sectional area and water supply flow but also reduces the overall reinforcement stability. At the same time, most devices are only suitable for single-diameter pipelines. In actual projects, when encountering water supply pipelines of different diameters, frequent equipment replacement is required, resulting in high construction costs, limited adaptability, and low efficiency.
[0004] Therefore, it is necessary to design a trenchless water supply pipeline lining reinforcement device. Utility Model Content
[0005] In order to overcome the shortcomings of existing devices, such as uneven pressurization leading to excessive lining gaps, affecting flow and stability, poor pipe diameter adaptability, frequent replacement, high cost and low efficiency, this utility model provides a water supply pipeline lining reinforcement device for trenchless construction.
[0006] The technical solution of this utility model is as follows: a water supply pipeline lining reinforcement device for trenchless construction, comprising a mounting cover, a second motor, a lead screw, a slider, a connecting rod, a hinge block, a connecting plate, guide rods, and a mounting plate. The second motor is mounted on the rear side of the mounting cover. The output shaft of the second motor passes through the mounting cover and is rotatably connected to it. A lead screw is connected to the output shaft of the second motor. A slider is threaded onto the lead screw. Multiple connecting rods distributed axially are rotatably connected to the slider. A hinge block is rotatably connected to the front side of each connecting rod. A connecting plate is fixedly connected to each hinge block. The connecting plates are slidably connected to the mounting cover. Multiple guide rods are fixedly connected to the outer side of each connecting plate. The guide rods are slidably connected to the mounting cover. A mounting plate is fixedly connected between the outer sides of the multiple guide rods on the same mounting cover.
[0007] Furthermore, it also includes a movable frame, a connecting frame, and pulleys. The connecting frame is fixedly connected to both the front and rear sides of the mounting cover. The movable frame is rotatably connected to the outside of the connecting frame. Multiple pulleys are rotatably connected inside the connecting frame, and the wheel surfaces of the pulleys are in contact with the inner wall of the movable frame.
[0008] Furthermore, it also includes a mounting bracket and a motor. The mounting bracket is fixedly connected inside the movable frame. The motor is installed at the rear of the front mounting bracket, and the output shaft of the motor is connected to the front connecting bracket.
[0009] Furthermore, it also includes rollers, with multiple rollers rotatably connected to the mounting plate.
[0010] Furthermore, it also includes ultraviolet lamps, with multiple ultraviolet lamps installed at the rear of the rear mounting bracket.
[0011] Furthermore, it also includes traction rings, with traction rings fixedly connected to the opposite sides of the two mounting brackets.
[0012] Beneficial effects: 1. By adjusting the sliding distance of the slider through the motor, the connecting plate expands outward synchronously through the connecting rod. The guide rod and the mounting plate maintain radial synchronous movement, ensuring that the inner lining hose is subjected to uniform force throughout the circumference. It is suitable for water supply pipes of different diameters and solves the problems of uneven pressurization in existing devices, which easily leads to excessive gaps in the inner lining, affecting flow and stability, as well as poor pipe diameter adaptability, frequent replacement, high cost and low efficiency.
[0013] 2. By setting up an ultraviolet lamp, the device does not need to be kept stationary during the curing stage. With the assistance of external traction, the ultraviolet lamp moves synchronously with the device and continuously irradiates the inner lining hose, achieving curing while moving. This ensures uniform curing quality, avoids overexposure or incomplete curing, and greatly improves the efficiency of continuous construction. Attached Figure Description

Detailed Implementation
[0019] Example: A trenchless construction method for reinforcing the lining of water supply pipelines, such as... Figure 1 , Figure 2 and Figure 3 As shown, the system includes a mounting cover 4, a second motor 5, a lead screw 6, a slider 7, a connecting rod 8, a hinge block 9, a connecting plate 10, a guide rod 11, a mounting plate 12, and a roller 13. The second motor 5 is mounted on the rear side of the mounting cover 4. The output shaft of the second motor 5 passes through the mounting cover 4 and is rotatably connected to it. The lead screw 6 is connected to the output shaft of the second motor 5. The slider 7 is threaded onto the lead screw 6. Four connecting rods 8 distributed axially are rotatably connected to the slider 7. The front side of each connecting rod 8 is rotatably connected to a hinge block 9. A connecting plate 10 is welded to each hinge block 9. The connecting plate 10 is slidably connected to the mounting cover 4 through a sliding groove. Two guide rods 11 are welded to the outer side of each connecting plate 10. The guide rods 11 are slidably connected to the mounting cover 4 through a sliding groove. A mounting plate 12 is welded between the outer sides of multiple guide rods 11 on the same mounting cover 4. Two rollers 13 are rotatably connected to each mounting plate 12.
[0020] like Figure 1 , Figure 2 and Figure 4 As shown, it also includes a movable frame 1, a motor 2, a connecting frame 3, pulleys 301, and a mounting frame 14. The mounting cover 4 has connecting frames 3 welded to both the front and rear sides. The movable frame 1 is rotatably connected to the outside of the connecting frame 3. Four pulleys 301 distributed along the axial direction are rotatably connected inside the connecting frame 3. The wheel surfaces of the pulleys 301 are in contact with the inner wall of the movable frame 1 to form rolling support. The mounting frame 14 is welded inside the movable frame 1. The motor 2 is installed at the rear of the front mounting frame 14. The output shaft of the motor 2 is connected to the front connecting frame 3.
[0021] like Figure 1 and Figure 4 As shown, it also includes ultraviolet lamps 15 and traction rings 16. Four ultraviolet lamps 15 are installed on the rear of the rear mounting bracket 14, which are distributed along the axis. Traction rings 16 are welded to the sides of the two mounting brackets 14 that are far apart from each other.
[0022] This device is equipped with a remote control, which is used to control motor 2, motor 5 and ultraviolet lamp 15. When this device is needed for the reinforcement of the lining of water supply pipes, the operator first puts the flexible lining hose, which has been pre-coated with slurry (such as cement-based slurry, epoxy resin, etc.), around the mounting plate 12 and roller 13. Then, the external winch traction rope is connected to the traction ring 16, and the winch can be started. The device is pulled along the pipeline axis by the traction rope, and the entire device, together with the lining hose, is sent from the pipeline inlet into the water supply pipe to be repaired.
[0023] Once the device is pulled to the designated position of the pipe section to be repaired, it is no longer pulled. Then, motors 2 and 5 are started. The output shaft of motor 2 rotates, driving the connecting frame 3 to rotate, which in turn drives the mounting cover 4 to rotate. At this time, pulleys 301 rotate within the connecting frame 3, and rolling friction replaces sliding friction. The auxiliary device overcomes the resistance of the inner wall of the pipe. The output shaft of motor 5 rotates, driving the lead screw 6 to rotate, which in turn drives the slider 7 to move forward along the lead screw 6. At this time, connecting rods 8 rotate on the corresponding sliders 7. By pushing the hinge block 9, multiple connecting plates 10 move outward synchronously and unfold. At this time, guide rods 11 slide on the mounting cover 4, and the mounting plate 12 opens outward, gradually lifting the flexible inner lining hose wrapped around it, bringing it closer to the original inner wall of the pipe, until the inner lining hose is fully opened and tightly attached to the original inner wall of the pipe. Then, motors 2 and 5 are turned off, and the device is pulled again to start the ultraviolet lamp 15. The light source of the ultraviolet lamp 15 radiates outward onto the inner lining material, and the resin undergoes a photopolymerization reaction.
[0024] After the liquid gradually solidifies into a hard solid structure, turn off the ultraviolet lamp 15 and pull the device out in the opposite direction using the rear traction ring 16. Check whether the solidified inner lining layer inside the original pipeline is flat and without cracks, thus completing the use process of this device.
