Description

Technical Field

[0001] The invention relates to the field of pipeline repair equipment, and in particular to a pipeline lining turnover repair machine and a use method thereof. Background Art

[0002] After long-term use, the anti-corrosion layer of underground pipelines gradually fails, and the inner wall of the pipeline corrodes, which brings many hidden dangers. Pipeline repair is one of the problems that must be solved in the process of urban construction. The flip lining method is a trenchless pipeline repair technology. It uses a fiber-reinforced hose or a braided hose impregnated with resin glue as the pipeline lining material. The lining is sent into the pipeline to be repaired by flipping it. The lining pipe is bonded to the inner wall of the pipeline to be repaired with glue to form a repair layer for the old pipeline. Compared with traditional excavation repair, trenchless repair has lower costs, which saves costs for urban municipal maintenance work.

[0003] Since the surface of the hose needs to be coated with glue after being flipped, the flip lining repair machine currently used needs to immerse the lining hose in an adhesive curing agent serving as glue before use. Specifically, the hose is filled with adhesive, and then the hose is rolled with a dipping machine to promote uniform distribution of the glue. The hose impregnated with glue is then continuously sent into the pipeline to be repaired through a flipper. However, since the length of a single section of a pipeline to be repaired in a city is usually more than 100 meters, it takes a long time to inject glue into the lining hose as a whole and then press it evenly before flipping the hose into the pipeline to be repaired, and the required operating space is large, resulting in high practical operation limitations. In addition, the glue is easily cured before the rear half of the hose is sent into the pipeline to be repaired, affecting the bonding effect and the ring stiffness of the pipeline in subsequent use after the repair. Summary of the invention

[0014] The method for using the pipeline lining flipping and repairing machine comprises the following steps: a. Extend one end of the injection tube out of the outer tube and insert it into the flat belt tube used as the repair material. At this time, the injection tube and the flat belt tube form a double-layer tube. The double-layer tube is wound around the outer circumference of the outer tube, and the outer free end of the flat belt tube is extended into the tube delivery box, and passes through the gap between the upper and lower rollers and along the outer tapered opening of the guide tube. The flat belt tube part passing through the guide tube port is turned outward, and the turned part of the flat belt tube is tightened to the outer circumference of the guide tube through a pipe clamp, completing the turning preparation process of the flat belt tube; b. Connect the one-way pipe joint at one end of the piston cylinder close to the liquid supply pipe to the external epoxy glue storage container, then turn on the drive motor to drive the lower pressure roller to rotate, and use the synchronous gear to keep the upper pressure roller rotating synchronously, so that the upper and lower pressure rollers cooperate to support the flat belt tube to be continuously transported into the tube delivery box. At the same time, the transmission shaft transmits the rotational power of the upper pressure roller to the outer cylinder to drive the outer cylinder to rotate synchronously to unfold the flat belt tube; c. During the rotation of the outer cylinder, the planetary gear on the rotating frame is used to transmit the rotational power of the outer cylinder to the inner cylinder, and the inner cylinder produces a rotational movement opposite to that of the outer cylinder. The large pulley at the rear end of the inner cylinder cooperates with the transmission belt to drive the eccentric wheel to rotate, and the eccentric wheel pulls the rotating push rod to drive the piston push rod to swing back and forth laterally. During the sliding movement of the piston push rod left and right in the piston cylinder, when the volume of the air cavity expands, air is pumped into the air cavity through the one-way pipe joint, and the volume of the air cavity is reduced. The air in the air cavity is introduced into the pipe delivery box along the air supply pipe, so as to use the air pressure in the pipe delivery box to push the flat belt tube to continuously turn outward and extend into the pipeline to be repaired. Similarly, when the volume of the liquid cavity expands, the glue in the external epoxy glue storage container is pumped into the liquid cavity through the one-way pipe joint. When the volume of the liquid cavity is reduced, the glue in the liquid cavity is introduced into the inner cylinder along the liquid supply pipe and the rotating disk, and is output from the inside of the flat belt tube along the glue injection pipe, so that the pressurized gas and the adhesive are synchronously pumped in the process of the air pressure cooperating with the two sets of pressure rollers to push the flat belt tube to turn outward and extend into the pipeline to be repaired. d. While the driving motor is used as the power source of the tube delivery box to push the flat belt tube, the transmission shaft is used to synchronously drive the outer cylinder to realize the unfolding of the flat belt tube, and the planetary gear is used to reversely rotate the inner cylinder during the rotation of the outer cylinder, so that the glue injection tube inserted inside the flat belt tube is rolled up and stored to the outer circumference of the inner cylinder during the unfolding of the flat belt tube, so as to ensure that the glue outlet port of the glue injection tube is always kept inside the flat belt tube, and the glue injection tube is prevented from extending out of the flat belt tube due to the eversion action of the flat belt tube, and the rotational tube pushing action of the tube delivery box to maintain the position is synchronously adjusted with the rotational unfolding action of the outer cylinder, the rotational storage action of the glue injection tube, the injection speed of the adhesive and the air supply and pressurization speed of the air supply pipe.

[0015] The beneficial effects are as follows: 1. The present invention provides a glue injection tube inside the flat belt tube as a repair hose, and extends the outer port of the glue injection tube to the position of the tube delivery box, and uses the glue injection tube to inject glue into the inside of the flat belt tube flip position, so as to change the traditional pre-impregnation construction method, and has lower requirements on the construction area, and can solve the problem that the flat belt tube is easily solidified in the second half before reaching the bonding position due to the overall glue impregnation in the early stage, thereby ensuring the repair effect; 2. A transmission shaft is set to drive and connect the two sets of rollers for squeezing and pushing the flat belt tube with the outer cylinder for rotating and unfolding the flat belt tube, and the outer cylinder and the inner cylinder are kept rotating in opposite directions through the planetary gear, so that while the outer cylinder unfolds the flat belt tube and the glue injection tube inside it, the glue injection tube is continuously withdrawn by the inner cylinder to ensure that the outer port of the glue injection tube is always located at the position of the tube delivery box, so as to ensure the continuous glue injection action of the glue injection tube to the flipping position of the flat belt tube; 3. An eccentric wheel connected with a transmission belt is arranged on the outer end surface of the inner tube, and the eccentric wheel is used to drive the piston push rod to cooperate with the piston tube to form an air pressure pumping mechanism and a glue pumping mechanism, so as to realize the glue injection action synchronously during the turning process of the flat belt tube, and pump air and increase pressure into the pipe delivery box through the air supply pipe, and assist the pressure roller to push the flat belt tube, so as to improve the smoothness of the flat belt tube as a lining hose to be turned and delivered into the pipeline to be repaired; 4. A set of driving motors is used as the power source for the rotation and pushing action of the pressure roller, and as the power source for the rotation and expansion of the flat belt tube by the outer cylinder, the rotation and storage of the injection tube by the inner cylinder, the injection of adhesive and the gas pressurization power source in the tube delivery box. The multi-station repair mechanism is integrated and the speed is adjusted synchronously to ensure the repair efficiency and the compactness of the equipment structure.

The opening width of the through groove 505 is larger than the outer diameter of the injection tube 9 and smaller than the thickness of the flat belt tube 2, so as to prevent the injection tube 9 from pulling the flat belt tube 2 into the through groove 505; A restraining ring 701 is fixed on the outer end surface of the rotating frame 7, which extends into the inner part of the outer cylinder 5 and rotates to cooperate with the restraining groove 504, thereby improving the stability of the rotating frame 7 supporting the outer cylinder 5 to rotate.

In addition, an eccentric wheel 11c is fixed to the rear end of the side shaft 11a. The piston cylinder 17 is a hollow structure. A piston push rod 17a is slidably arranged inside the piston cylinder 17. The piston push rod 17a is T-shaped, and one end of the piston push rod 17a close to the eccentric wheel 11c passes out of the piston cylinder 17. The piston push rod 17a is slidably sealed with the piston cylinder 17. The piston push rod 17a includes a piston block and a push rod section. The piston cylinder 17 is divided into a gas chamber and a liquid chamber with variable volumes by the piston block. Specifically, the liquid chamber is close to the eccentric wheel 11c, and the outer end of the piston push rod 17a is hinged with a rotating push rod 17b. The outer end of the rotating push rod 17b is hinged with the eccentric end face of the eccentric wheel 11c. When the inner cylinder 6 drives the eccentric wheel 11c to rotate by using the transmission belt 11d, the piston push rod 17a can be pulled by the rotating push rod 17b to slide back and forth along the piston cylinder 17. The top side of the piston cylinder 17 is provided with an air supply pipe 17c and a liquid supply pipe 17d that are connected to the air chamber and the liquid chamber respectively.

[0022] The method of using the pipe lining flip repair machine includes the following steps: a. Extend one end of the injection tube 9 out of the outer cylinder 5 and insert it into the flat belt tube 2 as the repair material. At this time, the injection tube 9 and the flat belt tube 2 form a double-layer tube, which is wound around the outer circumference of the outer cylinder 5, and the outer free end of the flat belt tube 2 is extended into the tube delivery box 1, and passes through the gap between the upper pressure roller 103 and the lower pressure roller 104 and passes along the outer tapered opening of the guide cylinder 101, and the part of the flat belt tube 2 that passes through the port of the guide cylinder 101 is turned outward, and the turned part of the flat belt tube 2 is tightened to the outer circumference of the guide cylinder 101 through the pipe clamp 16, completing the turning preparation process of the flat belt tube 2; b. Connect the one-way pipe joint 17e at one end of the piston cylinder 17 close to the liquid supply pipe 17d to the external epoxy glue storage container, and then turn on the driving motor 3 to drive the lower pressure roller 104 to rotate, and use the synchronous gear 105 to keep the upper pressure roller 103 rotating synchronously, so that the upper pressure roller 103 and the lower pressure roller 104 cooperate to support the flat belt tube 2 to be continuously transported into the tube delivery box 1. At the same time, the transmission shaft 4 transmits the rotational power of the upper pressure roller 103 to the outer cylinder 5 to drive the outer cylinder 5 to rotate synchronously to unfold the flat belt tube 2; c. During the rotation of the outer cylinder 5, the planetary gear 703 on the rotating frame 7 is used to transmit the rotational power of the outer cylinder 5 to the inner cylinder 6. The inner cylinder 6 produces a rotational movement opposite to that of the outer cylinder 5. The large pulley 603 at the rear end of the inner cylinder 6 cooperates with the transmission belt 11d to drive the eccentric wheel 11c to rotate. The eccentric wheel 11c pulls the rotating push rod 17b to drive the piston push rod 17a to swing back and forth laterally. When the piston push rod 17a slides left and right in the piston cylinder 17, when the air cavity volume expands, air is pumped into the air cavity through the one-way pipe joint 17e, and the air cavity volume shrinks. The air in the air cavity moves along the supply The air pipe 17c is introduced into the pipe delivery box 1, so as to utilize the air pressure in the pipe delivery box 1 to push the flat belt tube 2 to continuously evert and extend into the pipe to be repaired. Similarly, when the volume of the liquid cavity is expanded, the glue in the external epoxy glue storage container is pumped into the liquid cavity through the one-way pipe joint 17e. When the volume of the liquid cavity is reduced, the glue in the liquid cavity is introduced into the inner cylinder 6 along the liquid supply pipe 17d and the rotating disk 12, and is output from the inside of the flat belt tube 2 along the glue injection pipe 9. In this way, in the process of the air pressure cooperating with the two sets of pressure rollers to push the flat belt tube 2 evert and extend into the pipe to be repaired, the pressurized gas and the adhesive are pumped synchronously; d.

10. The method for using the pipeline lining flipping and repairing machine according to claim 9 is characterized in that: The following steps are involved: a. Extend one end of the injection tube (9) out of the outer tube (5) and insert it into the flat belt tube (2) used as the repair material. At this time, the injection tube (9) and the flat belt tube (2) form a double-layer tube. The double-layer tube is wound around the outer circumference of the outer tube (5). The outer free end of the flat belt tube (2) is extended into the tube delivery box (1), and passes through the gap between the upper pressure roller (103) and the lower pressure roller (104) and passes along the outer tapered opening of the guide tube (101).

Connect the one-way pipe joint (17e) at one end of the piston cylinder (17) close to the liquid supply pipe (17d) to an external epoxy glue storage container, then turn on the drive motor (3) to drive the lower pressure roller (104) to rotate, and use the synchronous gear (105) to keep the upper pressure roller (103) rotating synchronously, so that the upper pressure roller (103) and the lower pressure roller (104) cooperate to support the flat belt tube (2) to be continuously transported into the tube delivery box (1), and at the same time, the transmission shaft (4) transmits the rotational power of the upper pressure roller (103) to the outer cylinder (5), so as to drive the outer cylinder (5) to rotate synchronously to unfold the flat belt tube (2); c. During the rotation of the outer cylinder (5), the planetary gear (703) on the rotating frame (7) is used to transmit the rotational power of the outer cylinder (5) to the inner cylinder (6), and the inner cylinder (6) generates a rotational motion opposite to that of the outer cylinder (5). The large pulley (603) at the rear end of the inner cylinder (6) cooperates with the transmission belt (11d) to drive the eccentric wheel (11c) to rotate. The eccentric wheel (11c) pulls the rotating push rod (17b) to drive the piston push rod (17a) to swing back and forth laterally. During the sliding movement of the piston push rod (17a) left and right in the piston cylinder (17), when the volume of the air cavity expands, air is sucked into the air cavity through the one-way pipe joint (17e), and the volume of the air cavity shrinks. The air in the cavity is introduced into the pipe delivery box (1) along the air supply pipe (17c), so that the air pressure in the pipe delivery box (1) is used to push the flat belt tube (2) to continuously turn outward and extend into the pipe to be repaired. Similarly, when the volume of the liquid cavity is expanded, the glue in the external epoxy glue storage container is pumped into the liquid cavity through the one-way pipe joint (17e). When the volume of the liquid cavity is reduced, the glue in the liquid cavity is introduced into the inner cylinder (6) along the liquid supply pipe (17d) and the rotating disk (12), and is output from the flat belt tube (2) along the glue injection pipe (9). In this way, in the process of the air pressure cooperating with the two sets of pressure rollers to push the flat belt tube (2) to turn outward and extend into the pipe to be repaired, the pressurized gas and the adhesive are pumped synchronously; d. While the driving motor (3) is used as the power source of the tube delivery box (1) to push the flat belt tube (2), the transmission shaft (4) is used to synchronously drive the outer cylinder (5) to realize the unfolding of the flat belt tube (2), and the planetary gear (703) is used to reversely rotate the inner cylinder (6) during the rotation of the outer cylinder (5), so that the glue injection tube (9) inserted inside the flat belt tube (2) is rolled up and stored on the outer circumference of the inner cylinder (6) during the unfolding of the flat belt tube (2), so as to ensure that the glue outlet port of the glue injection tube (9) is always kept inside the flat belt tube (2), and the glue injection tube (9) is prevented from extending out of the flat belt tube (2) due to the eversion action of the flat belt tube (2), and the rotation pushing action of the tube delivery box (1) is kept in the synchronous adjustment with the rotation unfolding action of the outer cylinder (5), the rotation storage action of the glue injection tube (9), the injection speed of the adhesive, and the air supply and pressurization speed of the air supply pipe (17c).
