Technical Field

[0001] The utility model relates to the field of civil engineering, in particular to a novel pneumatic grouting pump. Background Art

[0002] As a type of engineering equipment, pneumatic grouting pumps are primarily used for grouting and water blocking, void filling, and reinforcing broken rock formations in construction sites such as mines, tunnels, water conservancy projects, subways, buildings, and bridges. Their operating principle is to utilize compressed air as a power source, generating high injection pressure through the ratio of the effective area of ​​the air cylinder to the grouting cylinder, thereby enabling the transport and injection of various slurries.

[0003] The grouting pump is mainly moved by the moving wheels installed at the bottom. However, since the moving wheels are only installed at the bottom of the grouting pump to support the pump body, the moving wheels will move under the vibration force generated during the operation of the grouting pump during use, causing the grouting pump to shift. As a result, the pipes between them are affected by the displacement of the grouting pump, causing them to become stretched or even damaged. How to solve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

A movable component 7 is provided on the top of the workbench 1. The movable component 7 consists of a supporting unit and a moving unit. The supporting unit is located on the outer wall of the workbench 1, and the moving unit is located on the outer wall of the supporting unit. A clamping component 8 is provided at the bottom of the workbench 1.

[0031] The supporting unit includes a driving motor 701, a driving rod 702, a gear 1 703, a gear 2 704, a sleeve 705, a threaded rod 706, a movable plate 707, a bent rod 708 and a buffer rod 709. The driving motor 701 is fixedly connected to the top of the workbench 1, the driving rod 702 is installed at the output end of the driving motor 701, the gear 1 703 is fixedly connected to one end of the driving rod 702, the gear 2 704 is installed on the outer wall of the gear 1 703, the gear 1 703 is meshed with the gear 2 704, and when the gear 1 703 rotates, it can drive the gear 2 704 to rotate, the sleeve 705 is fixedly connected to the bottom of the gear 2 704, the sleeve 705 is rotatably connected to the inside of the workbench 1, the gear 2 704 can drive the sleeve 705 to rotate inside the workbench 1, and the threaded rod 706 is set at the workbench. At the bottom of the table 1, the threaded rod 706 passes through the sleeve 705 and extends to the outside of the sleeve 705. The outer wall of the threaded rod 706 is adapted to the inner wall of the sleeve 705. When the sleeve 705 rotates, the threaded rod 706 will move under the action of the thread, and the movable plate 707 is fixedly connected to the bottom end of the threaded rod 706. The bent rod 708 is fixedly connected to the outer wall of the movable plate 707. The end of the bent rod 708 away from the movable plate 707 passes through the workbench 1 and extends to the top of the workbench 1. The outer wall of the bent rod 708 is slidably connected to the inner wall of the workbench 1. The existence of the bent rod 708 can limit the rotation of the threaded rod 706. When the movable plate 707 moves, the bent rod 708 can slide inside the workbench 1, and the buffer rod 709 is fixedly connected to the bottom of the movable plate 707.

[0032] The moving unit includes gear three 710, a frame 711 and a universal wheel 712. Gear three 710 is fixedly connected to the outer wall of the driving rod 702. The frame 711 is installed on the outer wall of gear three 710. The frame 711 passes through the workbench 1 and extends to the outside of the workbench 1. The outer wall of the frame 711 is slidably connected to the inner wall of the workbench 1. The interior of the frame 711 is provided with a card groove and a tooth groove. Gear three 710 is engaged with the tooth groove. The universal wheel 712 is installed at the bottom of the frame 711. When gear three 710 rotates, the tooth groove can push the frame 711 to move, thereby adjusting the position of the universal wheel 712.

[0033] By setting a driving motor 701 and a driving rod 702, when the driving motor 701 is started, the driving rod 702 will drive gear 1 703 and gear 3 710 to rotate. At this time, gear 1 703 drives gear 2 704 to rotate, so that the threaded rod 706 pulls the buffer rod 709 to move under the action of the thread. When gear 3 710 rotates, the universal wheel 712 is pulled to move through the frame 711, so that after the buffer rod 709 contacts the ground, the universal wheel 712 will be separated from the ground. At this time, the grouting pump can be supported by the buffer rod 709, thereby ensuring the stability of the grouting pump during operation; solving the problem that the existing grouting pump cannot ensure the stable operation of the pump body only by the moving wheel during operation.

The electric push rod 801 can push the clamping rod 802 to pass through the frame 711 and move to the inside of the clamping frame 803, thereby reducing the supporting pressure of gear three 710.

[0035] By setting the clamping rod 802 and the clamping frame 803, the universal wheel 712 is lowered so that the bottom of the universal wheel 712 contacts the ground, and the buffer rod 709 is separated from the ground. At this time, the operation of the electric push rod 801 is controlled so that the electric push rod 801 pushes the clamping rod 802 to pass through the frame 711 and is clamped into the inside of the clamping frame 803, completing the limitation of the frame 711, so that the universal wheel 712 can stably support the grouting pump through the clamping frame 803 and the clamping rod 802.

[0036] The working principle of this new type of pneumatic grouting pump is as follows: after the grouting pump is moved to the specified position, the operation of the driving motor 701 is controlled to make the driving rod 702 drive gear 1 703 and gear 3 710 to rotate. When gear 1 703 rotates, the sleeve 705 is driven to rotate through gear 2 704, so that the threaded rod 706 pushes the buffer rod 709 down under the action of the thread and contacts the ground until the universal wheel 712 is separated from the ground; when gear 3 710 rotates, the frame 711 will rise under the action of the tooth groove. When the frame 711 rises, it will drive the universal wheel 712 to move until the bottom end of the buffer rod 709 contacts the ground. After completing the support of the grouting pump, the grouting pump body 2 is started, so that external materials enter the interior of the grouting pump body 2 through the pipeline 4, and are processed inside the grouting pump body 2 and then discharged through the pipeline 4.

Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
