Description

Technical Field

[0001] This utility model relates to the field of grouting pumps, and specifically to a grouting pump. Background Technique

[0002] As an indispensable part in the fields of civil engineering, construction engineering, tunnel engineering, and mining engineering, grouting technology is widely used in foundation reinforcement, crack repair, anti-seepage and plugging, tunnel support, etc.

[0003] In the current grouting process, the mixing and grouting processes are carried out separately, which requires two devices. It is necessary to first mix the cement slurry well and then transfer it to the grouting pump for grouting, increasing the operation steps and time costs. Moreover, due to static placement, the cement slurry will precipitate and agglomerate during the placement process, affecting the grouting effect. Content of the Utility Model

[0004] In order to overcome the above deficiencies, this utility model provides a grouting pump.

[0006] A grouting pump includes a mixing barrel and a vertical pump. The front side of the top of the mixing barrel is fixedly connected with a feed hopper, and the feed hopper is communicated with the mixing barrel. The top and bottom of the inner side wall of the mixing barrel are respectively fixedly connected with an upper fixing plate and a lower fixing plate. There is a movable pipe between the upper fixing plate and the lower fixing plate. The outer wall of the top of the movable pipe is rotatably connected with the middle of the upper fixing plate, and the outer wall of the bottom of the movable pipe is rotatably connected with the middle of the lower fixing plate. The vertical pump is located inside the movable pipe and is rotatably connected with the inner wall of the movable pipe. The bottom of the vertical pump is fixedly communicated with a feeding pipe, and the feeding pipe is located at the bottom inside the mixing barrel. The output end of the vertical pump is fixedly communicated with a discharge pipe, and the discharge pipe is located above the upper fixing plate on the left side. The outer wall of the movable pipe is fixedly connected with a number of uniformly distributed stirring blades. The top of the movable pipe penetrates through the upper fixing plate and is fixedly connected with a pulley one. The pulley one is annular and located outside the vertical pump. The right side wall of the mixing barrel is fixedly installed with a motor, the top end of the output shaft of the motor is fixedly connected with a transmission shaft, the top end of the transmission shaft is fixedly connected with a pulley two, the pulley two is flush with the pulley one, and a belt is sleeved between the outer walls of the pulley two and the pulley one.

Detailed Embodiment

[0017] As Figures 1-6As shown: A grouting pump includes a mixing barrel 1 and a vertical pump 5. A feed hopper 2 is fixedly connected to the front side of the top of the mixing barrel 1. The feed hopper 2 is communicated with the mixing barrel 1. An upper fixing plate 3 and a lower fixing plate 4 are respectively fixedly connected to the top and bottom of the inner side wall of the mixing barrel 1. There is a movable pipe 9 between the upper fixing plate 3 and the lower fixing plate 4. The outer wall of the top of the movable pipe 9 is rotatably connected to the middle of the upper fixing plate 3, and the outer wall of the bottom of the movable pipe 9 is rotatably connected to the middle of the lower fixing plate 4. The vertical pump 5 is located inside the movable pipe 9 and is rotatably connected to the inner wall of the movable pipe 9. The bottom of the vertical pump 5 is fixedly communicated with a feed pipe 6, and the feed pipe 6 is located at the inner bottom of the mixing barrel 1. The output end of the vertical pump 5 is fixedly communicated with a discharge pipe 7, and the discharge pipe 7 is located above the left side of the upper fixing plate 3. A plurality of uniformly distributed stirring blades 10 are fixedly connected to the outer wall of the movable pipe 9. The top of the movable pipe 9 penetrates through the upper fixing plate 3 and is fixedly connected with a pulley one 11. The pulley one 11 is annular and located outside the vertical pump 5. A motor 12 is fixedly installed on the right side wall of the mixing barrel 1. The top end of the output shaft of the motor 12 is fixedly connected with a transmission shaft 13, and the top end of the transmission shaft 13 is fixedly connected with a pulley two 14. The pulley two 14 is flush with the pulley one 11, and a belt 15 is sleeved between the outer walls of the pulley two 14 and the pulley one 11.

[0018] A fixing block 8 is fixedly connected to the outer wall of the discharge pipe 7, and the fixing block 8 is fixedly connected to the top of the upper fixing plate 3.

[0019] The fixing block 8 on the outside of the discharge pipe 7 ensures the stability and fixed position of the discharge pipe 7, preventing shaking or deviation during the grouting process.

[0020] First, pour the cement raw materials into the mixing barrel 1 through the feed hopper 2. The design of the feed hopper 2 enables the cement to smoothly enter the interior of the mixing barrel 1, preparing for the subsequent mixing process.

[0021] Start the motor 12. The output shaft of the motor 12 drives the transmission shaft 13 to rotate, thereby driving the pulley two 14 to rotate. Since the pulley two 14 and the pulley one 11 are connected by a belt 15, the pulley one 11 will also rotate accordingly. The pulley one 11 is fixedly connected to the top of the movable pipe 9, so the movable pipe 9 will rotate around the rotation connection points at its upper and lower ends. The rotation of the movable pipe 9 drives the stirring blades 10 fixed on its outer wall to rotate together. The stirring blades 10 fully stir the cement in the mixing barrel 1, ensuring the uniform mixing of the cement and maintaining the activity of the cement.

[0022] After the cement is evenly stirred, start the vertical pump 5. The vertical pump 5 extracts the cement at the bottom of the mixing barrel 1 through the feed pipe 6 at its bottom. Since the vertical pump 5 is rotatably connected to the inner wall of the movable pipe 9, its operation will not be affected by the rotation of the movable pipe 9. The extracted cement is compressed and pushed by the vertical pump 5 and is discharged from the discharge pipe 7 for grouting operation. The present utility model only protects the mechanical part, and the functions realized by the software control part related thereto are not within the protection scope of the present utility model.
