[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Example 1, referring to Figures 1-7 This is the first embodiment of the present utility model. This embodiment provides a high-pressure grouting pump for deep well mines, including a grouting pump body 1, with lifting rings 3 at each of the four corners of the grouting pump body 1.

[0031] The moving mechanism 2 includes two U-shaped frames 22, which are fixed to the bottom of both sides of the grouting pump body 1. Each U-shaped frame 22 is provided with two moving blocks 21, and each moving block 21 is provided with a moving hole 23. The moving block 21 is fitted onto the U-shaped frame 22 through the moving hole 23. A fixing mechanism 5 is provided inside the moving block 21.

[0032] The rotating component 6 includes a hollow plate 61, a worm 62, and a worm wheel 63. The hollow plate 61 is fixed to the top of the moving block 21. One end of the worm 62 is rotatably connected to the inner wall of one side of the hollow plate 61 through a bearing, and the other end passes through one side of the hollow plate 61 and is fixed with a knob. A rotating rod 64 is rotatably provided on the bottom inner wall of the hollow plate 61 through a bearing. The worm wheel 63 is fixedly sleeved on the rotating rod 64 and meshes with the worm 62.

[0033] The rotating component 6 also includes a turntable 65, the bottom of which is rotatably connected to the top of the hollow plate 61, and the top of the rotating rod 64 passes through the top of the hollow plate 61 and is fixedly connected to the bottom of the turntable 65. The lifting ring 3 is fixedly connected to the top surface of the turntable 65.

[0034] The movable block 21 in the movable mechanism 2 can slide on the U-shaped frame 22. In conjunction with the fixed mechanism 5, the position of the lifting ring 3 can be adjusted according to the change of the center of gravity of the grouting pump, ensuring that the pump body remains balanced during hoisting and greatly improving the safety of hoisting operations. The angle of the lifting ring 3 can be adjusted by the rotating part 6 to meet diverse usage needs and enhance the adaptability of the equipment in different scenarios.

[0035] Specifically, the fixing mechanism 5 includes a cavity 53, a movable frame 52, an insertion rod 55, and a pressing rod 51. The cavity 53 is opened inside the movable block 21. The movable frame 52 is located inside the cavity 53 and is slidably connected to the inner wall of the movable block 21. The movable hole 23 passes through the movable frame 52. The insertion rod 55 is fixed to one side of the inner wall of the movable frame 52. The inner side of the U-shaped frame 22 has multiple insertion holes, and the insertion rod 55 can be inserted into the insertion holes.

[0036] The fixing mechanism 5 also includes a spring 54 fixed to the inner wall of one side of the movable block 21. The other end of the spring 54 is fixed to one side of the movable frame 52. A circular hole is provided on one side of the movable block 21. One end of the pressing rod 51 extends out of the movable block 21 through the circular hole and can slide in the circular hole. The other end of the pressing rod 51 is fixed to the movable frame 52. A blocking member 4 is provided on the side of the movable block 21 near the pressing rod 51.

[0037] Press the pressing lever 51, and the pressing lever 51 will slide in the round hole opened on one side of the moving block 21. The pressing lever 51 will drive the moving frame 52 to slide in the cavity 53, compressing the spring 54. At the same time, the insertion rod 55 will protrude from the insertion hole of the U-shaped frame 22. Keep the pressing lever 51 pressed down and slide the moving block 21 to a suitable position. Then, align the insertion rod 55 with the corresponding insertion hole on the U-shaped frame 22. Release the pressing lever 51. Under the elastic force of the spring 54, the moving frame 52 will return to its original position, driving the insertion rod 55 to be inserted into the insertion hole of the U-shaped frame 22, thereby fixing the moving block 21.

[0038] Specifically, the shielding component 4 includes a fixing ring 42 and a cover 41. The fixing ring 42 is fixed to the side of the movable block 21 where the pressing rod 51 is provided. The fixing ring 42 surrounds the round hole. The pressing rod 51 is located inside the fixing ring 42. The outer side of the fixing ring 42 is provided with external threads. The inner wall of the cover 41 is provided with internal threads. The cover 41 is threadedly connected to the fixing ring 42.

[0039] Take the cover 41 and thread it to the fixing ring 42 to cover the pressing rod 51 and prevent accidental contact with the pressing rod 51.

[0040] Example 2, refer to Figures 1 to 7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0041] Specifically, a stabilizing member 7 is provided on one side of the hollow plate 61. The stabilizing member 7 includes an L plate 73 and a wing screw 71. The L plate 73 is fixed to one side of the hollow plate 61, and the wing screw 71 is threadedly connected to the L plate 73. The surface of the turntable 65 is provided with insertion holes 72 arranged in a ring array.

[0042] The wing screw 71 in the rotating stabilizer 7 is screwed into the corresponding insertion hole 72 on the surface of the turntable 65. When the lifting ring 3 is subjected to external force, it can resist the external force and prevent the lifting ring 3 from rotating, thereby reducing the damage between the worm gear 63 and the worm 62.

[0043] Specifically, the lifting ring 3 is welded to the surface of the turntable 65.

[0044] The lifting ring 3 is welded to the surface of the turntable 65, making the connection between the lifting ring 3 and the turntable 65 more secure.

[0045] Specifically, a reinforcing plate 31 is welded to the surface of the turntable 65, with both ends of the reinforcing plate 31 located on both sides of the lifting ring 3.

[0046] The reinforcement plate 31 can enhance the stability between the lifting ring 3 and the turntable 65, making it less likely for the lifting ring 3 and the turntable 65 to separate.

[0047] Specifically, both sides of the movable block 21 are fixed with a protective frame 24 in the shape of a quadrangular truncated pyramid, the protective frame 24 covers the movable hole 23, and the outer side of the U-shaped frame 22 is slidably connected to the inner wall of the protective frame 24.

[0048] When the moving block 21 moves, it will drive the guard frame 24 to move, which can reduce the entry of impurities between the moving hole 23 and the U-shaped frame 22.

[0049] Specifically, a flow meter 11 is fixedly installed at the outlet end of the grouting pump body 1.

[0050] During the grouting process, the value displayed by the flow meter 11 at the outlet end of the grouting pump body 1 can be observed. The working parameters of the grouting pump can be adjusted according to actual needs, and the flow rate can be measured.

[0051] The flow meter 11 and the grouting pump body 1 are existing technologies, which are clearly known to those skilled in the art, and will not be described in detail here.

[0052] During hoisting, pressing the pressing rod 51 will cause the pressing rod 51 to slide in the round hole on one side of the moving block 21. The pressing rod 51 will drive the moving frame 52 to slide in the cavity 53, compressing the spring 54, and at the same time causing the insertion rod 55 to protrude from the insertion hole of the U-shaped frame 22.

[0053] Keeping the pressing lever 51 pressed down, slide the moving block 21 to the appropriate position so that the insertion rod 55 is aligned with the corresponding insertion hole on the U-shaped frame 22.

[0054] Release the pressing rod 51. Under the elastic force of the spring 54, the moving frame 52 returns to its original position, causing the insertion rod 55 to be inserted into the insertion hole of the U-shaped frame 22, thereby fixing the moving block 21. Take out the cover 41 and thread it to the fixing ring 42 to cover the pressing rod 51 and prevent accidental contact.

[0055] When it is necessary to adjust the angle of the lifting ring 3, rotate the knob on one side of the hollow plate 61 to drive the worm gear 62 to rotate. Since the worm wheel 63 meshes with the worm gear 62, the rotation of the worm gear 62 will drive the worm wheel 63 to rotate, which in turn drives the rotating rod 64, the turntable 65 and the lifting ring 3 to rotate. Adjust the direction and align the insertion hole 72 with the wing screw 71 (the insertion hole 72 on the turntable 65 corresponds one-to-one with the tooth groove of the worm wheel 63). Rotate the wing screw 71 in the stabilizing component 7 so that the wing screw 71 is screwed into the corresponding insertion hole 72 on the surface of the turntable 65. When the lifting ring 3 is subjected to external force, it can resist the external force, prevent the lifting ring 3 from rotating abnormally, and reduce the damage between the worm wheel 63 and the worm gear 62.

[0056] During the grouting process, the value displayed by the flow meter 11 at the outlet end of the grouting pump body 1 can be observed. The working parameters of the grouting pump can be adjusted according to actual needs (where the flow meter 11 is connected to the outlet end of the grouting pump body 1 through a flange, and the external pipeline is connected to the other end of the flow meter 11 through a flange).

[0057] The material and specifications of the spring 54 can be selected according to actual needs. The flow meter 11 should preferably be a mud flow meter, and the specific selection can be made according to actual needs. The model of the grouting pump body 1 can be XPB-90E high-pressure grouting pump, which is existing technology and will not be described in detail here.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
