Description

Technical Field

[0001] The utility model relates to the technical field of geopolymer grouting, in particular to a grouting head fixing fixture for geopolymer grouting. Background Art

[0002] Geopolymer material is an alkali-activated cementitious material with the characteristics of high strength, high fluidity, good permeability and good adhesion. It is used in building materials, high-strength materials, solid nuclear and solid waste materials, sealing materials and high-temperature resistant materials.

[0003] The existing grouting head is usually fixedly connected with the grouting pipe by means of threads. Although this connection method is relatively stable, it requires multiple rotations during connection, which is time-consuming and laborious, cannot be connected quickly, and is inconvenient for users.

[0004] For example, the grouting head docking assembly for geopolymer grouting process disclosed in Chinese patent CN215674090U has a sealing effect for the top of the grouting pipe and the inner cavity of the lower slurry pipe by the arrangement of two rubber pads. The grouting pipe can be limited by the arrangement of the circular ring block and the oblique block 1, so that the grouting pipe can be stably located in the inner cavity of the lower slurry pipe, thereby achieving the purpose of facilitating quick docking. This solves the problem that the existing grouting head is usually fixedly docked with the slurry flow pipe by means of threads. Although this docking method is relatively stable, it requires multiple rotations during docking, which is time-consuming and labor-intensive, cannot be docked quickly, and is inconvenient for users.

[0005] However, the grouting head does not have a filtering structure inside, so that the particulate matter in the slurry cannot be filtered, which may cause the slurry outlet of the grouting head to be blocked.

[0006] For this reason, we urgently need to provide a grouting head fixing fixture for geopolymer grouting with filtering function. Utility Model Content

[0007] The purpose of the utility model is to provide a grouting head fixing fixture for geopolymer grouting, so as to solve the problem that the grouting head proposed in the above background technology has no filtering structure inside, so that the particulate matter in the slurry cannot be filtered, which will cause the slurry outlet of the grouting head to be blocked.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a grouting head fixing fixture for geopolymer grouting, comprising a grouting pipe and a grouting head, wherein the grouting head is connected to the right end of the grouting pipe, and the inner and outer ends of the grouting pipe and the grouting head are connected with a grouting mechanism, wherein the grouting mechanism comprises a filtering unit and a fixing unit, wherein the filtering unit is arranged on the inner side of the grouting head, and the fixing unit is arranged on the outer ends of the grouting pipe and the grouting head.

[0009] The filter unit includes a fixing ring, a threaded rod, a cylinder, a filter element and a pressure ring. The fixing ring is fixedly connected to the inner left end of the grouting head, the threaded rod is fixedly connected to the middle position of the front and rear ends of the left side of the fixing ring, the cylinder is connected to the outer end of the threaded rod, the filter element is connected to the left side of the fixing ring, and the pressure ring is connected to the left side of the filter element.

[0010] A further improvement is that the filter element and the pressure ring are provided with limiting holes at both ends, and the outer side of the threaded rod is slidably connected to the inner side of the limiting holes. Therefore, when the filter element is slid to the left side of the fixing ring and the pressure ring is slid to the left side of the filter element, the limiting holes at both ends of the filter element and the pressure ring will pass through the outer side of the threaded rod, thereby limiting the movement of the filter element and the pressure ring during assembly and disassembly.

[0011] A further improvement is that the inner side of the cylinder is provided with an internal thread, the inner side of the cylinder is threadedly connected with the outer side of the threaded rod, the right side of the filter element abuts with the left side of the fixed ring, the right side of the pressure ring abuts with the left side of the filter element, the right side of the cylinder abuts with the front and rear ends of the left side of the pressure ring, and the outer edges of the filter element and the pressure ring are slidably connected with the inner side of the grouting head. Thus, the filter element is slid to the left side of the fixed ring, and the pressure ring is slid to the left side of the filter element. At the same time, after the threaded rod passes through the limiting hole, the cylinder is threadedly connected to the outer side of the threaded rod until the right side of the cylinder contacts the front and rear ends of the left side of the pressure ring, so that the filter element can be fixed between the fixed ring and the pressure ring, so that the slurry sprayed through the grouting head will be filtered by the filter element, preventing the particles in the slurry from clogging the slurry outlet at the right end of the grouting head.

[0012] A further improvement is that the fixing unit includes a right connecting ring, a left connecting ring, a connecting plate, a rectangular frame, a connecting frame, a spring, a circular ring and an insert rod, the right connecting ring is fixedly connected to the outer left end of the grouting head, the left connecting ring is fixedly connected to the outer right end of the grouting pipe, the connecting plate is fixedly connected to the upper and lower ends of the outer sides of the right connecting ring and the left connecting ring, the rectangular frame is connected to the outer end of the connecting plate, the connecting frame is fixedly connected to the middle position of the right side of the rectangular frame, the spring is fixedly connected to the inner right end of the connecting frame, the circular ring is fixedly connected to the left end of the spring, and the insert rod is fixedly connected to the inner side of the circular ring.

[0013] A further improvement is that sliding holes are provided in the middle of the left and right ends of the rectangular frame and the middle of the right end of the connecting frame, and the outer side of the insertion rod is slidably connected to the inner side of the sliding hole. Therefore, when the spring drives the ring to move, the insertion rod will slide along the inner side of the sliding hole, thereby limiting the movement of the insertion rod.

[0014] A further improvement is that a plug hole is provided in the middle of the upper end of the connecting plate, the outer sides of the two connecting plates that are in contact with the outer sides of the right connecting ring and the left connecting ring are slidably connected to the inner side of the rectangular frame, and the outer side of the left end of the plug rod is plugged into the inner side of the plug hole. Therefore, after the rectangular frame is slid to the outer sides of the two connecting plates that are in contact with the outer sides of the right connecting ring and the left connecting ring, the spring rebounds and pushes the circular ring to the left, driving the plug rod to move left together, until the left end of the plug rod moves left to the plug hole at the upper end of the connecting plate, the connecting plates at the outer ends of the right connecting ring and the left connecting ring can be clamped and fixed to the inner side of the rectangular frame, so that the right connecting ring and the left connecting ring are relatively fixed, and the grouting head is fixed to the right end of the grouting pipe, so that the grouting pipe and the grouting head can be easily disassembled and assembled through the clamping and fixing structure.

[0015] A further improvement is that a rubber pad is fixedly connected to the left side of the right connecting ring. Therefore, after the right connecting ring is fixed to the right side of the left connecting ring, the rubber pad on the left side of the right connecting ring contacts the right side of the left connecting ring, so that the contact point between the right connecting ring and the left connecting ring can be kept sealed, preventing slurry from leaking from the contact point between the right connecting ring and the left connecting ring during grouting.

[0016] In summary, the present application discloses a grouting head fixing fixture for geopolymer grouting.

[0017] According to the technical solution, the filter element is slid to the left side of the fixing ring, and then the pressure ring is slid to the left side of the filter element. After the threaded rod passes through the limiting hole, the cylinder is threadedly connected to the outside of the threaded rod until the right side of the cylinder contacts the front and rear ends of the left side of the pressure ring. The filter element can be fixed between the fixing ring and the pressure ring, so that the slurry sprayed through the grouting head will be filtered by the filter element to prevent the particles in the slurry from clogging the slurry outlet at the right end of the grouting head.

[0018] Furthermore, after the rectangular frame is slid to the outside of the two connecting plates that are in contact with the outside of the right connecting ring and the left connecting ring, the circular ring is pushed left by the spring rebound, driving the insertion rod to move left together, until the left end of the insertion rod moves left to the insertion hole at the upper end of the inner part of the connecting plate, the connecting plates at the outer ends of the right connecting ring and the left connecting ring can be clamped and fixed to the inner side of the rectangular frame, so that the right connecting ring and the left connecting ring are relatively fixed, and the grouting head is fixed to the right end of the grouting pipe, so that the disassembly and assembly of the grouting pipe and the grouting head can be very convenient through the clamping and fixing structure.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in 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 in 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.

[0025] See also Figure 1-Figure 4 , the utility model provides a technical solution: Example

[0026] A grouting head fixing fixture for geopolymer grouting comprises a grouting pipe 1 and a grouting head 2, wherein the grouting head 2 is connected to the right end of the grouting pipe 1, and inner and outer ends of the grouting pipe 1 and the grouting head 2 are connected with a grouting mechanism, wherein the grouting mechanism comprises a filtering unit and a fixing unit, wherein the filtering unit is arranged on the inner side of the grouting head 2, and the fixing unit is arranged on the outer ends of the grouting pipe 1 and the grouting head 2.

[0027] The filter unit includes a fixing ring 301, a threaded rod 302, a cylinder 303, a filter element 304 and a pressing ring 305. The fixing ring 301 is fixedly connected to the inner left end of the grouting head 2, the threaded rod 302 is fixedly connected to the middle position of the front and rear ends of the left side of the fixing ring 301, the cylinder 303 is connected to the outer end of the threaded rod 302, the filter element 304 is connected to the left side of the fixing ring 301, and the pressing ring 305 is connected to the left side of the filter element 304. The filter element 304 and the pressing ring 305 are provided with limiting holes at the front and rear ends inside, and the outer side of the threaded rod 302 is slidably connected to the inner side of the limiting hole. Therefore, when the filter element 304 is slid to the left side of the fixing ring 301 and the pressing ring 305 is slid to the left side of the filter element 304, the limiting holes at the front and rear ends inside the filter element 304 and the pressing ring 305 will pass through the outer side of the threaded rod 302, thereby playing a limiting role in the movement of the filter element 304 and the pressing ring 305 when disassembling.

[0028] An internal thread is provided on the inner side of the cylinder 303, and the inner side of the cylinder 303 is threadedly connected to the outer side of the threaded rod 302. The right side of the filter element 304 abuts against the left side of the fixing ring 301, and the right side of the pressure ring 305 abuts against the left side of the filter element 304. The right side of the cylinder 303 abuts against the front and rear ends of the left side of the pressure ring 305, and the outer edges of the filter element 304 and the pressure ring 305 are slidably connected to the inner side of the grouting head 2. Thus, the filter element 304 is slid to the left side of the fixing ring 301, and then the pressure ring 305 is slid to the left side of the filter element 304. At the same time, after the threaded rod 302 passes through the limiting hole, the cylinder 303 is threadedly connected to the outside of the threaded rod 302 until the right side of the cylinder 303 contacts the front and rear ends of the left side of the pressure ring 305. The filter element 304 can be fixed between the fixing ring 301 and the pressure ring 305, so that the slurry sprayed through the grouting head 2 will be filtered by the filter element 304 to prevent the particles in the slurry from clogging the slurry outlet at the right end of the grouting head 2.

The right connecting ring 401 is fixedly connected to the left end of the outer side of the grouting head 2, the left connecting ring 402 is fixedly connected to the outer side of the right end of the grouting pipe 1, the connecting plate 403 is fixedly connected to the upper and lower ends of the outer sides of the right connecting ring 401 and the left connecting ring 402, the rectangular frame 404 is connected to the outer end of the connecting plate 403, the connecting frame 405 is fixedly connected to the middle position of the right side of the rectangular frame 404, the spring 406 is fixedly connected to the inner right end of the connecting frame 405, the circular ring 407 is fixedly connected to the left end of the spring 406, and the plug rod 408 is fixedly connected to the inner side of the circular ring 407. Sliding holes are provided in the middle positions of the left and right ends inside the rectangular frame 404 and the middle position of the right end inside the connecting frame 405, and the outer side of the plug rod 408 is slidably connected to the inner side of the sliding hole. Therefore, when the spring 406 bounces and drives the ring 407 to move, it drives the insertion rod 408 to slide along the inner side of the sliding hole, thereby limiting the movement of the insertion rod 408.

[0030] A plug hole is provided in the middle of the upper end of the connecting plate 403. The outer sides of the two connecting plates 403 that are in contact with the outer sides of the right connecting ring 401 and the left connecting ring 402 are slidably connected to the inner side of the rectangular frame 404. The outer side of the left end of the plug rod 408 is plugged into the inner side of the plug hole. Therefore, after the rectangular frame 404 is slid to the outside of the two connecting plates 403 that are in contact with the outside of the right connecting ring 401 and the left connecting ring 402, the spring 406 rebounds to push the circular ring 407 to the left, driving the insertion rod 408 to move left together, until the left end of the insertion rod 408 moves left to the insertion hole at the upper end of the inner part of the connecting plate 403, the connecting plates 403 at the outer ends of the right connecting ring 401 and the left connecting ring 402 can be clamped and fixed to the inner side of the rectangular frame 404, so that the right connecting ring 401 and the left connecting ring 402 are relatively fixed, and the grouting head 2 is fixed to the right end of the grouting pipe 1, so that the disassembly and assembly of the grouting pipe 1 and the grouting head 2 can be very convenient through the clamping and fixing structure.
