Technical Field

[0001] The utility model relates to the technical field of PE welded pipes, in particular to a device for repairing the inner wall of a PE welded pipe. Background Art

[0002] PE welded pipe is a pipe made of polyethylene material and connected by welding technology. PE welded pipe has excellent corrosion resistance, wear resistance and aging resistance, and is suitable for various environments and usage scenarios. It is widely used in urban water supply, drainage, gas, heat, electricity, communications, agricultural irrigation and other fields. Among them, water pipes and gas pipes are its two largest application markets. During the use of PE welded pipes, its inner wall will inevitably be damaged. Sometimes due to cost, geographical environment and other factors, it is not suitable to replace a large number of PE welded pipes. At this time, it is necessary to use a repair device to repair the inner wall of the PE welded pipe.

DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 and Figure 2As shown, a PE welded pipe inner wall repair device includes a device body 1, a plurality of grooves 2 are arranged on the device body 1, a lifting plate 3 is arranged in the groove 2, a connecting groove 4 is arranged on one side of the lifting plate 3, a traction rope 5 is fixedly arranged in the connecting groove 4, a telescopic column 6 is arranged on the outer wall of one side of the device body 1, a positioning block 7 is arranged at the end of the telescopic column 6 away from the device body 1, a wire reel 8 is arranged on the positioning block 7, and a plurality of first temporary storage grooves 9 are arranged on the side of the device body 1 close to the positioning block 7.

[0024] like Figure 3 and Figure 4 As shown, in another embodiment of the utility model, the lifting plate 3 includes a lifting plate body 301, a sealing slide groove 302 is provided on the lifting plate body 301, a retaining wall 303 is provided in the sealing slide groove 302, and a spring 304 is provided on an outer wall below the retaining wall 303;

[0025] A second temporary storage groove 305 is provided on one side of the lifting plate body 301 close to the positioning block 7, a guide groove 306 is provided on the baffle wall 303, a sliding baffle 307 is provided in the guide groove 306, and a sensor 308 is provided on the sliding baffle 307. When it is necessary to repair the inner wall of the PE welded pipe, the sliding baffle 307 is first moved along the trajectory of the guide groove 306 in the direction of the positioning block 7 for a distance, and then the repair material is placed in the cavity formed by the baffle wall 303 and the lifting plate body 301, and then the sliding baffle 307 is returned to its original position, and the cavity formed by the baffle wall 303 and the lifting plate body 301 is closed by the sliding baffle 307 to prevent the repair material from escaping from the cavity formed by the baffle wall 303 and the lifting plate body 301, and then the lifting plate body 301 is moved to the position where the repair is required. The position to be repaired is then moved to the position to be repaired through the device body 1. When the sensor 308 senses that the outer wall surface of one side of the retaining wall 303 and the sliding baffle 307 are in contact with the inner wall surface of the PE welded pipe, the sliding baffle 307 is moved a distance in the direction of the positioning block 7 through the traction rope 5, and the sealing of the cavity formed by the retaining wall 303 and the lifting plate body 301 by the sliding baffle 307 is released. Subsequently, the lifting plate body 301 is continued to move toward the inner wall surface of the PE welded pipe through the device body 1, and the lifting plate body 301 is used to gradually fit the repair material to the inner wall surface of the PE welded pipe. At the same time, a section of the retaining wall 303 gradually enters the sealing slide groove 302, and the sliding baffle 307 gradually enters the second temporary storage groove 305. The spring 304 contracts, so that the inner wall surface of the PE welded pipe is repaired with the repair material.

[0026] The working principle of this PE welded pipe inner wall repair device:

[0027] When in use, first move the sliding baffle 307 along the trajectory of the guide slot 306 toward the direction of the positioning block 7 for a distance, then place the repair material in the cavity formed by the baffle wall 303 and the lifting plate body 301, then return the sliding baffle 307 to its original position, use the sliding baffle 307 to close the cavity formed by the baffle wall 303 and the lifting plate body 301, then use the telescopic column 6 to move the device body 1 to the place where repair is required, then use the device body 1 to move the lifting plate 3 to the position where repair is required, and when the sensor 308 senses that the outer wall surface of one side of the baffle wall 303 and the sliding baffle 307 is in contact with the inner wall surface of the PE welded pipe, the traction rope 5 is reeled in by the reel 8, and the traction rope 5 moves the sliding baffle 307 toward the positioning block 7. Move a certain distance to release the closure of the cavity formed by the retaining wall 303 and the lifting plate body 301 by the sliding baffle 307, and then use the device body 1 to make the lifting plate body 301 continue to move toward the inner wall surface of the PE welded pipe, and use the lifting plate body 301 to make the repair material gradually fit with the inner wall surface of the PE welded pipe. At the same time, a section of the retaining wall 303 gradually enters the sealing slide groove 302, and the sliding baffle 307 gradually enters the second temporary storage groove 305. The spring 304 contracts. After the repair is completed, the lifting plate 3 returns to its original position. At this time, a part of the sliding baffle 307 enters the first temporary storage groove 9, and then the telescopic column 6 is used to return the device body 1 to its original position, and then the above operation is repeated, which can effectively prevent the repair material from accidentally detaching from the lifting plate 3 during the movement.

[0028] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
