Description

Technical Field

[0001] The present utility model relates to the field of grouting pumps, and specifically to a single-head pneumatic grouting pump. Background Art

[0002] As an important device in the engineering field, grouting pumps are widely used in grouting and water plugging works and grouting coagulation works for breaking rock formations in mines, tunnels, water conservancy, subways, buildings, etc. As one of them, pneumatic grouting pumps have been widely used in engineering practice with their unique working principles and advantages.

[0003] Pneumatic grouting pumps use compressed air as the power source, and through the coordinated work of the air cylinder and the grouting cylinder, the suction and discharge of grouting materials are realized. However, current pneumatic grouting pumps all use direct drive of the air cylinder, which requires a relatively high power for the air cylinder, and the stress on the output shaft of the air cylinder is relatively large, resulting in a short service life of the grouting pump. Content of the Utility Model

[0004] In order to overcome the above deficiencies, the present utility model provides a single-head pneumatic grouting pump.

[0005] The technical solution adopted by the present utility model is as follows:

[0006] A single-head pneumatic grouting pump includes a vehicle plate and a push rod. The push rod is located on the right side of the vehicle plate, and the bottom of the push rod is fixedly connected to the upper right side of the vehicle plate. A fixing frame is fixedly connected to the left side of the top of the vehicle plate, and a grouting pump is fixedly connected to the inner side of the top of the fixing frame. The bottom right side of the grouting pump is fixedly connected and communicated with a pressurizing pipe. A piston is provided inside the pressurizing pipe, and the piston is slidably matched with the inner wall of the pressurizing pipe. The right side wall of the piston is fixedly connected to a piston rod, and the piston rod extends to the right. A support frame is fixedly connected to the right side of the top of the vehicle plate, and an air cylinder is fixedly connected to the top of the support frame. A fixing seat is fixedly connected to the middle of the top of the vehicle plate, and the top of the fixing seat is rotatably connected to the bottom end of a connecting rod. The top end of the connecting rod is inclined to the right, and a first sliding hole is provided at a position slightly below the middle of the connecting rod. The right end of the piston rod is located inside the first sliding hole and is slidably matched with the first sliding hole. A second sliding hole is provided at the top of the connecting rod, and the left end of the piston rod of the air cylinder is located inside the second sliding hole and is slidably matched with the second sliding hole.

[0007] The piston rod is fixedly connected to two first clamping plates. The first sliding hole is between the two first clamping plates. A round rod passes through the two first clamping plates and the first sliding hole, and the round rod is fixedly connected to the two first clamping plates and is slidably matched with the first sliding hole. The left end of the piston rod of the air cylinder is fixedly connected to two second clamping plates. The second sliding hole is between the two second clamping plates. A round shaft passes through the second clamping plates and the second sliding hole, and the round shaft is fixedly connected to the second clamping plates and is slidably matched with the second sliding hole.

[0008] The beneficial effects of the present utility model are as follows:

[0009] The utility model utilizes the lever principle. The air cylinder can drive the connecting rod and the piston to move greatly with a small force, thereby improving the working efficiency of the grouting pump and reducing the power demand of the air cylinder, achieving an energy-saving effect. Starting and stopping the grouting pump can be realized by controlling the start and stop of the air cylinder, and the operation is simple and fast. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] As Figures 1-6As shown in the figure: A single-head pneumatic grouting pump, including a vehicle plate 1 and a push rod 13. The push rod 13 is located on the right side of the vehicle plate 1, and the bottom of the push rod 13 is fixedly connected to the upper right side of the vehicle plate 1. A fixed frame 2 is fixedly connected to the left side of the top of the vehicle plate 1. A grouting pump 3 is fixedly connected to the inner side of the top of the fixed frame 2. A pressurizing pipe 4 is fixedly connected to the bottom right side of the grouting pump 3. A piston 5 is provided inside the pressurizing pipe 4. The piston 5 is slidably fitted with the inner wall of the pressurizing pipe 4. A piston rod 6 is fixedly connected to the right side wall of the piston 5. The piston rod 6 extends to the right. A support frame 7 is fixedly connected to the right side of the top of the vehicle plate 1. A cylinder 8 is fixedly connected to the top of the support frame 7. A fixed seat 9 is fixedly connected to the middle of the top of the vehicle plate 1. The top of the fixed seat 9 is rotatably connected to the bottom end of a connecting rod 10. The top of the connecting rod 10 slopes to the right. A first sliding hole 11 is provided at a position slightly below the middle of the connecting rod 10. The right end of the piston rod 6 is located inside the first sliding hole 11 and is slidably fitted with the first sliding hole 11. A second sliding hole 12 is provided at the top of the connecting rod 10. The left end of the piston rod of the cylinder 8 is located inside the second sliding hole 12 and is slidably fitted with the second sliding hole 12.

[0018] The piston rod 6 is fixedly connected to two first clamping plates 14. The first sliding hole 11 is between the two first clamping plates 14. A round rod 15 passes through the two first clamping plates 14 and the first sliding hole 11. The round rod 15 is fixedly connected to the two first clamping plates 14. The round rod 15 is slidably fitted with the first sliding hole 11. The left end of the piston rod of the cylinder 8 is fixedly connected to two second clamping plates 16. The second sliding hole 12 is between the two second clamping plates 16. A round shaft 17 passes through the second clamping plates 16 and the second sliding hole 12. The round shaft 17 is fixedly connected to the second clamping plates 16. The round shaft 17 and the second sliding hole 12 are slidably fitted.

[0019] The grouting pump 3 can be moved to the position where grouting is required through the vehicle plate 1. When it is necessary to start the grouting pump 3 for grouting, first start the cylinder 8. The output shaft of the cylinder 8 starts to move to the left or right. The left end of the output shaft of the cylinder 8 is inserted into the second sliding hole 12 at the top of the connecting rod 10 and is slidably fitted with it. As the output shaft of the cylinder moves, it pushes or pulls the top of the connecting rod 10, causing the connecting rod 10 to rotate reciprocally with the fixed seat 9 as the center.

[0020] When the connecting rod 10 rotates, it drives the piston rod 6 to move left and right reciprocally through the first sliding hole 11. The other end of the piston rod 6 is fixedly connected to the piston 5. Therefore, the movement of the piston rod 6 will drive the piston 5 to do reciprocating linear motion inside the pressurizing pipe 4. The reciprocating motion of the piston 5 inside the pressurizing pipe 4 will cause pressure changes. When the piston 5 moves to the left, it compresses the air or liquid inside the pressurizing pipe 4, increasing the pressure inside the grouting pump 3. When the piston 5 moves to the right, it releases part of the pressure to prepare for the next compression. This reciprocating motion continues, thus maintaining a high-pressure state inside the grouting pump 3.

[0021] As the pressure inside the grouting pump 3 continuously increases, the high-pressure slurry enters the grouting pump 3 through the input pipeline of the grouting pump 3 and is injected into the target position from the output pipeline.
