Technical Field

[0001] The utility model relates to the technical field of coal seam water injection pumps, in particular to a water injection pump with stable support. Background Art

[0002] The pulse coal seam water injection pump is a kind of equipment specially used for coal mining. It is mainly used to inject water into the coal seam to improve the mining efficiency and safety of the coal seam. Coal seam water injection is not only the most effective technical means to control the dust generated during coal mining, but also can prevent impact ground pressure, soften the coal body and reduce cutting energy; soften the top coal to reduce the amount of large coal and improve the recovery rate. It can effectively control the water flow and pressure through pulse water injection, reduce the impact on the coal seam and maintain the stability of the coal seam.

[0003] However, existing water injection pumps are usually placed on the ground or installed on other equipment. When the water injection pump is placed on the ground, the coal mine ground may have potholes or unevenness, which may cause the water injection pump to easily deviate or vibrate greatly during operation, reducing the stability of the water injection pump. Therefore, the current water injection pump needs to be improved. Utility Model Content

[0004] The purpose of the present utility model is to provide a stably supported water injection pump to solve the problem raised in the above background technology that when the water injection pumps currently on the market are placed on the ground, the ground of the coal mine may be bumpy or uneven, which may cause the water injection pumps to easily deviate or vibrate greatly during operation, thereby reducing the stability of the water injection pumps.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a stably supported water injection pump, comprising a machine base and a base, a motor being provided at one end of the machine base, a pump body being provided at the other end of the machine base, the base being fixed below the motor and the pump body, support mechanisms being installed at the four corners of the machine base, the support mechanisms comprising a handle, a screw, a guide block, a telescopic column, an anti-sliding block and a foot pad, and screws being installed in the built-in grooves at the four corners of the machine base through bearings.

[0006] Preferably, one end of the screw is fixedly connected to a handle, the outer side of the screw is threadedly sleeved with a telescopic column, and guide blocks are fixed on both sides of the telescopic column.

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-Figure 3 The utility model provides a technical solution: a stably supported water injection pump, comprising a machine base 1 and a base 3, one end of the machine base 1 is provided with a motor 2, the other end of the machine base 1 is provided with a pump body 4, the base 3 is fixed below the motor 2 and the pump body 4, the pump body 4 and the motor 2 are connected through a coupling, a filter assembly 9 is installed at the end of the pump body 4 away from the motor 2, an outlet pipe 5 is connected above the pump body 4, and an inlet pipe 8 is connected above the filter assembly 9, and a protective cover 13 is installed on the machine base 1 near the middle of the coupling.

[0025] See also Figure 1-Figure 5 , a bubble meter 14 is installed above the protective cover 13, and a support mechanism 6 is installed at the four corners of the machine base 1, and the support mechanism 6 includes a handle 601, a screw 602, a guide block 603, a telescopic column 604, an anti-slide block 605 and a foot pad 606. The screw 602 is installed in the built-in groove of the four corners of the machine base 1 through a bearing, one end of the screw 602 is fixedly connected to the handle 601, and the outer side of the screw 602 is threadedly sleeved with the telescopic column 604, and guide blocks 603 are fixed on both sides of the telescopic column 604. The bottom end of the telescopic column 604 is connected to the foot pad 606, and the anti-slide block 605 is connected to the bottom of the foot pad 606. A guide groove 7 is opened on the inner wall of the machine base 1 near the guide block 603, and the guide groove 7 is slidably connected to the guide block 603, and the shape of the anti-slide block 605 is set to be annular.

[0026] During specific implementation, the water injection pump is usually placed on the ground or installed on other equipment. When the water injection pump is placed on the ground, the coal mine ground may have potholes or unevenness, which may cause the water injection pump to easily deviate or vibrate greatly during operation, reducing the stability of the water injection pump. The bubble meter 14 can be observed to determine whether the machine base 1 is placed stably. If the machine base 1 is not in a horizontal state, the handles 601 at the four corners of the machine base 1 can be rotated, and the handles 601 will drive the screw 602 to rotate. Due to the threaded engagement between the screw 602 and the telescopic column 604, the screw 602 moves downward on the outside of the telescopic column 604, and at the same time, the telescopic column 604 drives the guide block 603 to slide downward in the guide groove 7, and then the telescopic column 604 drives the foot pad 606 to extend out of the built-in slot of the machine base 1. By adjusting the height of the foot pad 606, the foot pad 606 can be supported on an uneven or pothole-prone position on the ground, stably supporting the machine base 1 and improving the working stability of the water injection pump.

[0027] See also Figure 1 、 Figure 2 and Figure 6 The base 3 is connected to a docking slider 10 near the bottom of the machine base 1, and a ball 15 is installed in the built-in groove below the docking slider 10. The base 1 is provided with a docking groove 11 on the inner side near the docking slider 10. A sliding structure is formed between the docking slider 10 and the docking groove 11. A positioning block 12 is fixed to the upper surface of the machine base 1 near the base 3. Threaded holes are provided on the inner sides of the base 3 and the machine base 1. The cross-sectional shapes of the docking slider 10 and the docking groove 11 are both set to trapezoidal.

[0028] During specific implementation, the motor 2 or pump body 4 on the water injection pump is usually installed on the machine base 1 only by bolts. When installing the bolts, it is necessary to manually control the threaded holes of the motor 2 or pump body 4 to align with the threaded holes on the machine base 1, which is more troublesome, and the bolts may become loose over a long period of time. When installing the motor 2 or pump body 4, the base 3 of the motor 2 or pump body 4 can be placed on one side of the machine base 1, and then the docking slider 10 is slid into the docking groove 11, while driving the ball 15 to slide in the docking groove 11, so that the motor 2 or pump body 4 is conveniently placed on the machine base 1, and then one end of the base 3 contacts the positioning block 12, so that the threaded holes of the base 3 are aligned with the threaded holes of the machine base 1, which is convenient for the staff to quickly install the bolts, thereby improving the convenience of the water injection pump.

[0029] Working principle: When using the water injection pump with stable support, first install the motor 2 and the base 3 of the pump body 4 on the machine base 1 through the docking slider 10 and the docking groove 11, and then stably support the machine base 1 on the ground through the bubble meter 14 and the support mechanism 6, and the foot pad 606 is easy to store. Then the motor 2 drives the pump body 4 to run, and the water flows into the filter component 9 from the water inlet pipe 8. The filter component 9 then filters the water flow, and the filtered water flow is discharged from the water outlet pipe 5. The setting of the support mechanism 6 and the docking slider 10 improves the stability and convenience of the water injection pump.
