Description

Technical Field

[0001] The present invention relates to the technical field of inspection wells, and in particular to a device and method for connecting an inspection well and a drainage pipe. Background Art

[0002] Inspection wells are an important part of the urban drainage system. They are mainly used to inspect, maintain and clean drainage pipes to ensure the smooth flow of the drainage system. Inspection wells are usually set up at the intersections, elbows, locations where the slope of the pipes changes, and places where pipes need to be inspected and cleaned.

[0003] The connection between the existing inspection well and the drainage pipe is filled with cement. During long-term use, the cement seal may gradually reduce its sealing performance due to problems such as expansion, contraction or aging of the cement, which may easily cause water leakage and affect the normal operation of the drainage system. In addition, cement seals usually require a long curing time, and high technical requirements are required during the construction process to ensure the stability and sealing effect of the sealing joint. Maintenance and repair are difficult. Once the cement seal is damaged or aged, it is troublesome to repair it. The original cement structure needs to be destroyed and re-constructed, which increases the maintenance cost and construction period. The cement seal connection with poor seismic resistance may break or shift when encountering an earthquake or ground subsidence, resulting in an unstable connection and difficulty in adapting to the thermal expansion and contraction of the pipe. The cement seal has strong rigidity and is difficult to adapt to the thermal expansion and contraction of the pipe due to temperature changes. In addition, the existing connection between the inspection well and the drainage pipe is constructed manually, which reduces work efficiency, and the center of the drainage pipe is difficult to locate, resulting in a loose seal. Summary of the invention

[0021] Preferably, one end of the clamping rod is connected to a connecting block by rotation, and a fixed clamping block is fixedly installed on one side of the connecting block, and the relative movement of the fixed clamping block clamps the feeding end of the connecting rubber ring.

[0022] Through the above technical scheme, in order to prevent leakage from the feed end of the connecting rubber ring when conveying the foaming agent, and to prevent the feed end of the connecting rubber ring from being detached from the plug-in conveying pipe due to pressure when conveying the foaming agent, the feed end of the connecting rubber ring that is sleeved on the plug-in conveying pipe is clamped by relative movement of the fixed clamping block, so that the feed end of the connecting rubber ring is fixed on the plug-in conveying pipe.

[0024] Through the above technical scheme, in order to seal the feed end of the connecting rubber ring and prevent the internal foaming agent from being affected by the outside world, after the switching rack is engaged with the switching gear, it is possible to drive the connecting block to turn, complete the switching between the fixed clamping block and the heating block, so that the heating block can be directed toward the connecting rubber ring, and the ball on the scraper can be pushed down after being pressed by the sliding groove track, thereby pushing the foaming agent in the feed end of the connecting rubber ring, so that the hot pressing of the feed end can complete the sealing.

[0025] The present invention provides a method for connecting a manhole to a drainage pipe, comprising the following steps: S1: First, put the connecting rubber ring onto the connecting port of the inspection well, and then rotate the self-locking gear according to the diameter of the inspection well mouth. The self-locking gear drives the rotating disk to rotate. The rotating disk drives the fixed ring in the limiting slide groove to move outward by using the arc groove. The inner surfaces of the multiple fixed rings can fit the outer surface of the inspection well, so that the fixed disk can be fixed in the inspection well.

[0026] S2: According to the position of the connection port of the inspection well, the fixed motor on the support frame is controlled to start. After the fixed motor is started, it drives the rotating gear to rotate. The rotation of the rotating gear drives the lifting threaded sleeve to descend, thereby driving the connection frame to descend, so that the center line of the support shell and the center line of the inspection well connection port are on the same horizontal line. After the rotating rod on the connection frame is rotated, the rotating rod uses the bevel gear to drive the pushing gear to rotate. After the pushing gear pushes the pushing rack slidably inserted on the connection frame to move horizontally, the pushing rack makes the support shell pass through the outer surface of the inspection well.

[0027] S3: After the drainage pipe is sleeved on the outer surface of the supporting shell, the supporting motor on the push rack is started, which drives the push gear plate to rotate. The push gear plate rotates to push the supporting block to move outward, and the reset spring is stretched. The supporting block is inserted into the groove on the inner wall of the drainage pipe to complete the support of the drainage pipe, and the rack is pushed to move, driving the drainage pipe to be inserted into the connecting rubber ring.

[0028] S4: Sleeve the feed end of the connecting rubber ring on the outer surface of the plug-in conveying pipe, and drive the push plate to move by pushing the hydraulic cylinder to start. The push plate drives the clamping rod to move relatively on the moving frame through the deflection connecting rod, and the fixed clamping block on the clamping rod clamps the feed end of the connecting rubber ring on the plug-in conveying pipe.

[0029] S5: After the delivery pump on the base is started, the foaming agent in the suction storage tank is delivered to the arc delivery pipe, and then delivered to the fixed connecting rubber ring through the arc delivery pipe, so that the space inside the connecting rubber ring is filled, and the supporting annular spring in the connecting rubber ring supports the connecting rubber ring to prevent the foaming agent from being blocked.

[0030] S6: After the filling is completed, the hydraulic cylinder is pushed to start, which drives the clamping rod to open and releases the clamping of the feeding end of the connecting rubber ring. The moving component controls the moving frame to move. After the switching gear at one end of the connecting block meets the switching rack on the switching frame, the connecting block rotates, so that the heating block faces the middle connecting rubber ring. The hydraulic cylinder is pushed to drive the clamping rod to move one end distance relatively, so that the heating block is close to the connecting rubber ring. The moving frame moves under the drive of the moving component, and the ball of one section of the scraper enters the pushing slide groove and moves along the trajectory of the pushing slide groove, pulling the scraper downward to contact the connecting rubber ring. After the moving frame moves, the scraper can remove the foaming agent in the feeding end of the connecting rubber ring. After the roller leaves the pushing slide groove, the scraper is reset. After the hydraulic cylinder is started, the heating block performs hot pressing on the feeding end of the connecting rubber ring that has scraped off the foaming agent, so that the feeding end is closed.

[0031] The beneficial effects of the present invention are: 1. By setting a connecting device, the drainage pipe and the inspection well can be sealed. The gap between the drainage pipe and the inspection well connection port can be filled by a connecting rubber ring. The inside of the connecting rubber ring can be filled with a foaming agent or concrete, so that the drainage pipe and the inspection well are tightly connected and are not affected by the thermal expansion and contraction of the drainage pipe and the influence of time, reducing the possibility of water leakage. The supporting annular spring allows the middle section of the connecting rubber ring to be propped up, which is convenient for the foaming agent to be fully filled, so that the drainage pipe and the inspection well are tightly connected and the possibility of water leakage is reduced. The existing connection between the inspection well and the drainage pipe is sealed by manually applying cement, which may cause the sealing to gradually decrease due to the expansion, contraction or aging of the cement, and easily cause water leakage, affecting the normal operation of the drainage system. Technical problems.

[0032] 2. By setting up a supporting device, the drainage pipe can be supported, which is convenient for filling the foaming agent with the connecting rubber ring. The position of the fixed ring can be adjusted by rotating the rotating disk, so that the fixed disk can adapt to inspection wells of various diameters. At the same time, by moving the pushing rack, the supporting mechanism can pass through the drainage pipe and push the rotation of the toothed disk. The supporting block can be inserted into the drainage pipe to support the drainage pipe and drive the drainage pipe to pass through the connecting port of the inspection well. The connecting rubber ring can be located on the inner wall of the connecting port and will not be pressed by the drainage pipe, so that the foaming agent can be filled evenly.

[0033] 3. By setting a conveying device, the connecting rubber ring can be automatically filled with foaming agent. In order to prevent the connecting rubber ring from leaking at the feeding end when conveying the foaming agent, and to prevent the feeding end of the connecting rubber ring from being separated from the plug-in conveying pipe by pressure when conveying the foaming agent, the feeding end of the connecting rubber ring sleeved on the plug-in conveying pipe is clamped by the relative movement of the fixed clamping block, so that the feeding end of the connecting rubber ring is fixed on the plug-in conveying pipe. In order to seal the feeding end of the connecting rubber ring and prevent the internal foaming agent from being affected by the outside world, after the switching rack is engaged with the switching gear, the connecting block can be driven to turn, and the switching between the fixed clamping block and the heating block can be completed, so that the heating block can face the connecting rubber ring, and the ball on the scraper can be pushed down after being pressed by the sliding groove track, and the foaming agent in the feeding end of the connecting rubber ring is pushed, so that the hot pressing of the feeding end can complete the sealing, thereby automatically filling the foaming agent, reducing the input of labor, and solving the technical problem that the connection between the existing inspection well and the drainage pipe is sealed by manually applying cement, which requires manual operation and reduces work efficiency.
