Description

Technical Field

[0001] The utility model relates to the technical field of grouting pumps, in particular to a hollow grouting anchor rod high-pressure grouting pump. Background Art

[0002] Grouting is the process of injecting grout into cracks, fault zones, or joints and fissures in a building's foundation. Grouting can improve the impermeability and integrity of the ground or building being grouted, improve foundation conditions, and ensure the safe operation of hydraulic structures.

[0003] High-pressure grouting pumps typically inject grout into anchor rods inserted into the ground, allowing the rod and concrete to remain embedded in the ground, reinforcing the surface. However, current high-pressure grouting pumps are mostly limited to grouting. Therefore, anchor rod installation requires a drilling device to insert the rod into the building, then remove the drilling device, connect the grouting pump to the rod, and finally perform grouting. This cumbersome process reduces the efficiency of building reinforcement. Utility Model Content

[0020] The following further describes the present utility model in detail with reference to the drawings.

[0021] Embodiment:

[0022] Referring to Figures 1 to 3 The high-pressure grouting pump of the hollow grouting bolt disclosed by the present utility model includes an outer shell 1. A feed hose is fixedly penetrated through the upper half of the outer shell 1. A first check valve 2 is fixedly sleeved on the outer peripheral side of the feed hose. A threaded barrel 3 is rotatably connected to one side of the outer shell 1. The outer shell 1 and the threaded barrel 3 are connected and communicated through a second check valve 4. A piston 5 is slidably connected in the outer shell 1. Two nut sleeves 6 are rotatably connected to the inner side wall of the outer shell 1. A gear 7 is fixedly sleeved on the outer peripheral surface of the nut sleeve 6. A screw rod 8 is threadedly connected in the nut sleeve 6. One end of the screw rod 8 is fixedly connected to the piston 5. A driving part 9 is arranged between the two screw rods 8. A rotating part 10 is arranged in the threaded barrel 3.

[0023] In this embodiment, the end of the feed hose far from the outer shell 1 is connected to a concrete storage tank. Concrete enters the outer shell 1 through the feed hose. The first check valve 2 only allows the concrete to move towards the outer shell 1 in the feed hose, and the second check valve 4 only allows the concrete to move from the outer shell 1 towards the threaded barrel 3. Therefore, when the piston 5 moves towards the threaded barrel 3, the concrete in the outer shell 1 is squeezed into the threaded barrel 3 and discharged from the threaded barrel 3. When the piston 5 moves in the direction away from the threaded barrel 3, a negative pressure is generated in the outer shell 1, and the concrete in the concrete tank enters the outer shell 1 through the feed hose. Therefore, when the piston 5 reciprocates, the concrete is continuously discharged through the threaded barrel 3.

[0024] Before inserting the anchor rod into the building, first threadedly connect the drill sleeve to the outer peripheral surface of the threaded cylinder 3, and then threadedly connect one end of the hollow anchor rod to the drill sleeve, thereby connecting the anchor rod to the threaded cylinder 3. When the threaded cylinder 3 rotates, it drives the anchor rod to rotate. Handles are fixedly connected to both the front and rear sides of the outer shell 1. When installing the anchor rod, the staff holds the handles tightly to press the anchor rod tightly against the ground. At this time, the rotation of the anchor rod can drill into the ground.

[0025] In a further preferred embodiment of the present utility model, as Figure 2 and Figure 3 shown, the driving part 9 includes a rotating sleeve 91 rotatably connected to the inner side wall of the outer shell 1. An external gear ring 92 is fixedly connected to one side of the rotating sleeve 91. The external gear ring 92 meshes with the two gears 7. A motor 93 is arranged inside the rotating sleeve 91. An adjusting part 94 is arranged on the side of the motor 93 away from the piston 5. The output end of the motor 93 is drivingly connected to a turntable 95. A plurality of clamping blocks 96 are fixedly connected to both opposite sides of the turntable 95. A plurality of first clamping grooves 97 are opened on the side of the external gear ring 92 away from the rotating sleeve 91. A plurality of clamping blocks 96 on the side of the turntable 95 close to the external gear ring 92 are all slidably inserted into the corresponding first clamping grooves 97.

[0026] The adjusting part 94 includes a fixing plate 941 fixedly connected to one side of the motor 93. A lead screw 942 is rotatably connected to one side of the fixing plate 941. The lead screw 942 passes through the inner side wall of the outer shell 1 and extends to the outside of the outer shell 1, and the lead screw 942 is threadedly connected to the outer shell 1. A plurality of limiting rods 12 are fixedly connected to the inner side wall of the outer shell 1. The limiting rods 12 slidably pass through the fixing plate 941.

[0027] In this embodiment, in the initial state, a plurality of clamping blocks 96 on the side of the turntable 95 close to the external gear ring 92 are all slidably inserted into the corresponding first clamping grooves 97. At this time, the motor 93 works to drive the turntable 95 to rotate. The turntable 95 drives the external gear ring 92 to rotate through the cooperation of the clamping blocks 96 and the clamping grooves. The rotation of the external gear ring 92 drives the two gears 7 to rotate. The gears 7 drive the screw sleeve 6 to rotate. The screw sleeve 6 drives the screw rod 8 and the piston 5 to move horizontally.

[0028] In a further preferred embodiment of the present utility model, as Figure 2 and Figure 3 shown, the rotating part 10 includes a driven rod 101 movably passing through the piston 5. A driven disc 102 is fixedly connected to one end of the driven rod 101 close to the turntable 95. A plurality of second clamping grooves 103 are opened on the side wall of the driven disc 102. The driven rod 101 rotatably passes through the inner side wall of the outer shell 1 and extends into the threaded cylinder 3. A plurality of side plates 104 are fixedly connected to the outer peripheral surface of the driven rod 101 at the position inside the threaded cylinder 3. The side plates 104 are fixedly connected to the inner wall of the threaded cylinder 3.

[0029] In this embodiment, when the lead screw 942 is rotated, it drives the fixed plate 941 to move horizontally. The fixed plate 941 drives the motor 93 and the turntable 95 to move. The clamping block 96 that was originally inserted into the first clamping groove 97 disengages from the first clamping groove 97, and the remaining clamping blocks 96 are inserted into the second clamping groove 103. At this time, the motor 93 operates to drive the driven disk 102 and the driven rod 101 to rotate. The driven rod 101 drives the side plate 104 and the threaded barrel 3 to rotate, and the threaded barrel 3 drives the hollow anchor rod to rotate. The outer peripheral surface of the driven rod 101 is completely sealed with the piston 5, and the concrete will not move to the side of the piston 5 close to the motor 93. The driven rod 101 can move horizontally relative to the piston 5 and can also rotate relative to the piston 5.

[0030] In a further preferred embodiment of the present utility model, as Figure 2 shown, an indicating rod 11 is fixedly connected to the outer peripheral surface of the threaded barrel 3, and the indicating rod 11 is in a vertical state.

[0031] In this embodiment, before wanting to drive the anchor rod to rotate, the threaded barrel 3 is manually adjusted so that the indicating rod 11 is in a vertical state, ensuring that when the lead screw 942 is rotated, the clamping block 96 can be inserted into the corresponding second clamping groove 103.

[0032] The implementation principle of the above embodiment is as follows:

[0033] First, rotate the lead screw 942 to drive the fixed plate 941 to move horizontally. The fixed plate 941 drives the motor 93 and the turntable 95 to move, and several corresponding clamping blocks 96 are inserted into the second clamping groove 103. Then, the drill sleeve is threadedly connected to the outer peripheral surface of the threaded barrel 3, and one end of the hollow anchor rod is threadedly connected to the drill sleeve, thereby connecting the anchor rod to the threaded barrel 3. The motor 93 operates to drive the turntable 95, the driven disk 102, the driven rod 101, the side plate 104 and the threaded barrel 3 to rotate. The threaded barrel 3 drives the anchor rod to rotate, and the staff holds the handle and presses the anchor rod tightly against the ground, and the rotating anchor rod drills into the ground.

[0034] Then, turn off the motor 93 and rotate the lead screw 942 to make the turntable 95 return to its initial position. The corresponding clamping block 96 is inserted into the first clamping groove 97. At this time, the motor 93 rotates reciprocally to drive the piston 5 to move horizontally reciprocally, and the concrete is continuously discharged into the hollow anchor rod through the threaded barrel 3. Finally, the installation and grouting operation of the anchor rod are completed, and the drill sleeve is removed.

[0035] The embodiments of this specific implementation manner are all preferred embodiments of the present utility model, and do not limit the protection scope of the present utility model accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model should be covered within the protection scope of the present utility model.
