[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A grouting machine for repairing building cracks, comprising

[0008] The mud pump assembly is used to transfer construction slurry. The bottom of the mud pump assembly is fixedly connected to the base frame. Both ends of the base frame are fixedly connected to end rods, and both end rods are connected to the fixed frame assembly.

[0009] The drive assembly, which provides power to the mud pump assembly, has its bottom fixedly connected to a support frame, the bottom of which is fixedly connected to a fixed frame assembly.

[0010] The fixing frame assembly includes a fixing frame with two adjustment structures on its inner side. Three clamping structures are fixedly connected to the top of each of the two adjustment structures. Two adjustment slots corresponding to the positions of the adjustment structures are provided on both sides of the fixing frame. The two adjustment structures correspond to the positions of the two end rods, respectively.

[0011] The clamping structure includes an arc-shaped clamp one and an arc-shaped clamp two rotatably connected to the arc-shaped clamp one; a connecting block is fixedly connected to the middle of the side of the arc-shaped clamp one and the arc-shaped clamp two that are far apart from each other, and a connecting piece one is rotatably connected to the two connecting blocks; a movable rod is fixedly connected to the middle of the bottom of the two connecting pieces one; and a sleeve is coaxially sleeved on the outside of the two movable rods.

[0012] The adjustment structure includes a movable frame, with two nuts symmetrically fixed at both ends of the movable frame. Adjusting bolts are threaded onto the inner sides of the four nuts, and the four adjusting bolts are located in the adjustment slots on both sides of the fixed frame.

[0013] As a further technical solution of this utility model, the space between the first arc-shaped clamp and the second arc-shaped clamp is for placing the end rod; the inner sides of the first arc-shaped clamp and the second arc-shaped clamp are both embedded with rubber layers, and both rubber layers are in contact with the end rod.

[0014] As a further technical solution of this utility model, the end of the movable rod away from the first connecting member is located inside the sleeve, and the end of the movable rod away from the first connecting member is coaxially and integrally provided with a limiting plate. The top of the sleeve is provided with an opening for the movable rod to pass through and move normally, and the diameter of the limiting plate is larger than the diameter of the opening at the top of the sleeve.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Please see Figure 1-13 In this embodiment of the utility model, a grouting machine for repairing building cracks includes...

[0039] The bottom of the mud pump assembly 1, which is used to transfer construction slurry, is fixedly connected to the base frame 5. Both ends of the base frame 5 are fixedly connected to end rods 6, and both end rods 6 are connected to the fixed frame assembly 2.

[0041] The fixing frame assembly 2 includes a fixing frame 21, which has two adjustment structures 23 on its inner side. Each of the two adjustment structures 23 has three clamping structures 22 fixedly connected to its top. Each side of the fixing frame 21 has two adjustment slots 24 corresponding to the positions of the adjustment structures 23. The two adjustment structures 23 correspond to the positions of the two end rods 6 respectively.

[0042] The clamping structure 22 includes an arc-shaped clamp 221 and an arc-shaped clamp 222 rotatably connected to the arc-shaped clamp 221; a connecting block 223 is fixedly connected to the middle of the side of the arc-shaped clamp 221 and the arc-shaped clamp 222 that are far apart from each other; a connecting piece 224 is rotatably connected to the two connecting blocks 223; a movable rod 225 is fixedly connected to the middle of the bottom of the two connecting pieces 224; and a sleeve 226 is coaxially sleeved on the outer side of the two movable rods 225.

[0043] The adjustment structure 23 includes a movable frame 231, with two nuts 233 symmetrically fixedly connected to both ends of the movable frame 231. Adjusting bolts 232 are threadedly connected to the inner sides of the four nuts 233, and the four adjusting bolts 232 are respectively located in the adjustment grooves 24 on both sides of the fixed frame 21.

[0045] By adopting the above technical solution and setting multiple clamping structures 22, the two end rods 6 are tightly clamped and fixed by the arc-shaped clamp 1 221 and arc-shaped clamp 222 using the gravity of the mud pump assembly 1 and the base frame 5. When the mud pump assembly 1 needs to be inspected or cleaned, it is only necessary to lift the mud pump assembly 1 and the base frame 5 to easily separate it from the multiple clamping structures.

In the cooperation structure of the movable rod 225 and the sleeve 226, the presence of the spring 227 plays a good role in buffering and resetting. When the end rod 6 is placed on the clamping structure 22, the spring 227 is compressed, and the movable rod 225 moves downward in the sleeve 226.

[0048] The movable frame 231 is U-shaped; three connecting parts 235 are symmetrically fixedly connected to both ends of the bottom of the movable frame 231, and rollers 234 are rotatably connected to the inner side of the six connecting parts 235. The bottom of the three rollers 234 located on the same side of the six rollers 234 are all in contact with the inner wall of one side of the fixed frame 21.

[0049] By adopting the above technical solution, the setting of the adjustment structure 23 makes the use of the entire grouting machine more flexible; by loosening the connection of the adjustment bolt 232 and nut 233, the moving frame 231 can move along the adjustment groove 24 in the fixed frame 21, so that the position of the clamping structure 22 can be adjusted according to actual needs to adapt to mud pump assembly 1 and base frame 5 of different sizes, thereby enhancing the versatility and applicability of the equipment.

[0050] In this embodiment, the mud pump assembly 1 includes a reduction gearbox 11, the bottom of which is fixedly connected to the top of the base frame 5, and the bottom of the base frame 5 is attached to the top of the fixed frame 21; one end of the reduction gearbox 11 is connected to a suction and discharge valve assembly 12, the bottom of the suction and discharge valve assembly 12 is connected to a suction pipe 13, and the top of the suction and discharge valve assembly 12 is connected to a grouting pipe 14.

[0051] The suction and discharge valve assembly 12 is connected to a three-way pipe 15 at the end away from the grouting pipe 14. One end of the three-way pipe 15 is fixedly connected to the pressure chamber 16, and the other end of the three-way pipe 15 is connected to the pressure relief valve 18. The top of the pressure chamber 16 is connected to the pressure gauge 17.

[0052] The drive assembly 3 includes a motor 31, the output shaft of which is connected to a transmission shaft 32; a pulley 33 is coaxially fixedly connected to the middle section of the transmission shaft 32, a pulley 34 is provided on one side of the pulley 33, and the pulley 33 is connected to the pulley 34 via multiple belts 35; the pulley 34 is connected to the input end of the reduction gearbox 11.

[0054] By adopting the above technical solution, the rubber layer 228 embedded on the sides of the arc-shaped clamp 221 and the arc-shaped clamp 222 not only increases the friction between the clamp and the end rod, making the clamping more stable, but also buffers the force between the end rod 6 and the arc-shaped clamp to a certain extent, reducing the wear on the end rod 6 and extending the service life of the equipment; the roller 234 at the bottom of the moving frame 231 fits against the inner wall of the fixed frame 21, making the moving frame 231 move more smoothly, reducing friction, and further improving the ease of operation of the adjustment structure.

[0055] The working principle of this utility model is as follows: By setting multiple clamping structures 22, the two end rods 6 are tightly clamped and fixed by the weight of the mud pump assembly 1 and the base frame 5 using the arc-shaped clamp 1 221 and arc-shaped clamp 222. When the mud pump assembly 1 needs to be inspected or cleaned, it is only necessary to lift the mud pump assembly 1 and the base frame 5 to easily separate them from the multiple clamping structures. The operation is simple and quick, greatly improving the efficiency of inspection or cleaning. In the cooperation structure of the movable rod 225 and the sleeve 226, the presence of the spring 227 plays a good role in buffering and resetting. When the end rod 6 is placed on the clamping structure 22, the spring 227 is compressed, and the movable rod 225 moves downward in the sleeve 226. When the end rod 6 is lifted, the elastic force of the spring 227 makes the movable rod 225 return to the upward position, which is convenient for the next use. In addition, the opening at the top of the sleeve 226 has enough space for the movable rod 225 to move, preventing the sleeve 226 from obstructing the moving movable rod 225.

[0056] The adjustment structure 23 makes the use of the entire grouting machine more flexible; by loosening the connection of the adjusting bolt 232 and nut 233, the moving frame 231 can move along the adjusting groove 24 in the fixed frame 21, so that the position of the clamping structure 22 can be adjusted according to actual needs to adapt to mud pump assembly 1 and base frame 5 of different sizes, thereby enhancing the versatility and applicability of the equipment.

[0057] The rubber layer 228 embedded on the sides of the arc-shaped clamp 221 and the arc-shaped clamp 222 not only increases the friction between the clamp and the end rod, making the clamping more stable, but also buffers the force between the end rod 6 and the arc-shaped clamp to a certain extent, reducing the wear on the end rod 6 and extending the service life of the equipment. The roller 234 at the bottom of the moving frame 231 fits against the inner wall of the fixed frame 21, making the moving frame 231 move more smoothly, reducing friction, and further improving the ease of operation of the adjustment structure.

[0058] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
