[0034] The technical scheme of the present invention will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The detachable connection between the grouting tube 1 and the sealing cover 2 belongs to the prior art.

[0037] In the initial state, the two engaging blocks 5 are mounted on the outer surface of the grouting gun head 4 .

[0038] When in use, move the grouting tube 1 to a position close to the prefabricated wall panel body (at this time the prefabricated wall panel body has been sealed, and the sealing operation is a conventional technical means in this field), pour the prepared grouting material into the grouting tube 1, and then cover the sealing cover 2, insert the end of the grouting gun head 4 into the grouting hole of the corresponding prefabricated wall panel body, and then adjust the angle of the grouting gun head 4 to ensure normal grouting material transportation, and then adjust the height of the lifting block 7 accordingly through the driving mechanism to prompt the lifting block 7 to move downward with the base plate 8 until the base plate 8 contacts the upper end surface of the floor slab. At this time, the base plate 8 cooperates with the lifting block 7 to support the outer surface of the grouting gun head 4. At this time, the staff only needs to use their feet to touch the side of the holding block 5 away from the prefabricated wall panel body to limit and fix the grouting gun head 4. There is no need to support the grouting gun head 4 with hands, which saves effort.

[0039] When the grouting operation is subsequently performed on the prefabricated wall panel body of the same size and specification, there is no need to adjust the position height of the lifting block 7.

Each driving mechanism includes a threaded rod 10 rotatably arranged on the upper end surface of the engaging block 5. The lower end thread of the threaded rod 10 penetrates into the lifting block 7, and a hand wheel 11 is fixed to the upper end of the threaded rod 10.

[0041] When the position height of the lifting block 7 needs to be adjusted, the staff can rotate the hand wheel 11 to drive the threaded rod 10 to rotate, thereby driving the lifting block 7 to move.

[0042] A lower plug block 12 and an upper plug block 13 are fixed on the side wall of one of the engaging blocks 5, and a lower slot 14 and an upper slot 15 are opened on the side wall of the other engaging block 5. A magnet layer 16 is fixed to the end of the lower plug block 12, and a magnet layer 2 17 is fixed on the inner wall of the lower slot 14. The magnet layer 16 and the magnet layer 2 17 are magnetically attracted to each other.

[0043] When installing the two engaging blocks 5 to the outer surface of the grouting gun head 4, first align the lower plug block 12 with the lower slot 14, align the upper plug block 13 with the upper slot 15, and then move the two engaging blocks 5 closer to each other until the lower plug block 12 is fully inserted into the lower slot 14. At this time, the magnet layer 16 and the magnet layer 2 17 are magnetically attracted to each other, thereby fixing the two engaging blocks 5 together. When the grouting gun head 4 is not convenient to use auxiliary components in some working scenarios, the two engaging blocks 5 can be moved away from each other until the lower plug block 12 is removed from the lower slot 14, which is convenient for disassembly and assembly.

[0044] The gas guiding assembly includes a mounting seat 18 fixed to the upper end surface of the sealing cover 2, and a gas guiding groove 19 is provided on the upper end surface of the mounting seat 18, and the gas guiding groove 19 penetrates into the grouting tube 1, and a connector 20 used in conjunction with the gas guiding groove 19 is fixed on the upper end surface of the mounting seat 18, and a ventilation hose 21 is connected to the upper end of the connector 20, and a lateral slide groove 22 is provided on one side of the mounting seat 18, and the gas guiding groove 19 penetrates the lateral slide groove 22, and a sealing plate 23 is slidably provided in the lateral slide groove 22, and a pull rope 24 is fixed to one side of the sealing plate 23, an elastic unit used in conjunction with the sealing plate 23 is provided on the mounting seat 18, a guide unit used in conjunction with the pull rope 24 is provided on the sealing cover 2, and a positioning unit used in conjunction with the pull rope 24 is provided on the grouting tube 1.

[0046] The staff can control the gas guide component to inject the air delivered by the air compressor and the ventilation hose 21 into the grouting tube 1. Under the action of the pressure in the grouting tube 1, the grouting material in the grouting tube 1 is discharged through the grouting pipe 3 and the grouting gun head 4.

[0047] In the initial state, the sealing plate 23 blocks the air guide groove 19, and the air flow cannot enter the grouting tube 1. When air needs to enter the grouting tube 1, the staff can pull the pull rope 24 to prompt the sealing plate 23 to move in the direction away from the mounting seat 18, thereby releasing the blockage of the air guide groove 19, and the air flow delivered by the ventilation hose 21 can be injected into the grouting tube 1 to cooperate with the discharge of grouting material. When the air flow is not needed to enter the grouting tube 1, the staff releases the pull rope 24, and the sealing plate 23 is reset under the action of the elastic unit, and continues to block and block the air guide groove 19. Compared with the traditional valve control on the top of the sealing cover 2, it is easy to use.

[0049] When the blocking plate 23 is moved by pulling the pull rope 24, the T-shaped block 26, the guide rod 27 and the limit block 28 will be moved together. During this process, the spring 29 is stretched and deformed to store elastic potential energy. When the blocking plate 23 needs to be reset, the elastic potential energy stored in the spring 29 is released, prompting the blocking plate 23 to return to its initial position.

[0050] The guide unit includes two mounting blocks 30 fixed to the outer surface of the sealing cover 2 , a fixed pulley 31 is rotatably arranged between the two mounting blocks 30 , the pull rope 24 passes around the surface of the fixed pulley 31 , and a limiting member is arranged between the two mounting blocks 30 .

[0051] The pull rope 24 is guided to move by the cooperation of the mounting block 30, the fixed pulley 31 and the limiting member.

[0052] The limiting member includes a rotating plate 32, wherein a rotating groove 33 is provided on the upper end surface of one mounting block 30, one end of the rotating plate 32 is rotatably arranged in the rotating groove 33, elastic clamping blocks 34 are fixed on both sides of the rotating plate 32, and a clamping groove 35 used to cooperate with the rotating plate 32 is provided on the upper end surface of the other mounting block 30.

[0060] Step 2: insert the end of the grouting gun head 4 into the grouting hole of the corresponding prefabricated wall panel body, then adjust the angle of the grouting gun head 4, and then adjust the height of the lifting block 7 accordingly through the driving mechanism, so that the lifting block 7 moves downward with the base plate 8 until the base plate 8 contacts the upper end surface of the floor slab;

[0061] Step three, use your feet to push against the side of the holding block 5 away from the prefabricated wall panel body to limit and fix the grouting gun head 4. At this time, the grouting gun head 4 can pour material into the grouting hole.

[0062] When the present invention is in use, the grouting tube 1 is moved to a position close to the prefabricated wall panel body (at this time, the prefabricated wall panel body has been sealed), the prepared grouting material is poured into the grouting tube 1, and then the sealing cover 2 is covered, and the end of the grouting gun head 4 is inserted into the grouting hole of the corresponding prefabricated wall panel body, and then the angle of the grouting gun head 4 is adjusted so that it can ensure normal grouting material transportation, and then the height of the lifting block 7 is adjusted accordingly through the driving mechanism to prompt the lifting block 7 to move downward with the base plate 8 until the base plate 8 contacts the upper end surface of the floor slab. At this time, the base plate 8 cooperates with the lifting block 7 to support the outer surface of the grouting gun head 4. At this time, the staff only needs to use their feet to touch the side of the holding block 5 away from the prefabricated wall panel body to limit and fix the grouting gun head 4, and there is no need to support the grouting gun head 4 with their hands, which saves effort in operation;

[0063] The staff can control the gas guide component to inject the air delivered by the air compressor and the ventilation hose 21 into the grouting tube 1. Under the action of the pressure in the grouting tube 1, the grouting material in the grouting tube 1 is discharged through the grouting pipe 3 and the grouting gun head 4. In the initial state, the sealing plate 23 blocks the air guide groove 19, and the air flow cannot enter the grouting tube 1. When air needs to enter the grouting tube 1, the staff can pull the pull rope 24 to cause the sealing plate 23 to move in a direction away from the mounting seat 18, thereby releasing the blockage of the air guide groove 19, and the air delivered by the ventilation hose 21 can be injected into the grouting tube 1 to cooperate with the discharge of the grouting material. When the air flow is not needed to enter the grouting tube 1, the staff releases the pull rope 24, and the sealing plate 23 is reset under the action of the elastic unit to continue to block and block the air guide groove 19. Compared with the valve control at the top of the sealing cover 2 in the traditional way, it is convenient to use;

[0064] When in use, the engaging block 36 can be inserted into the engaging slot 38 to limit and fix the end of the pull rope 24. At this time, the pull rope 24 is in a taut state to prevent the pull rope 24 from swinging left and right during use, which is inconvenient for users to operate.
