Description

Technical Field

[0001] The utility model relates to the technical field of emulsion pumps, in particular to an emulsion pump base. Background Art

[0002] Emulsion pumps are used in coal mining working faces to provide emulsion for hydraulic supports. The working principle relies on the rotation of the crankshaft to drive the piston to do reciprocating motion to achieve liquid suction and discharge. Emulsion pumps are easy to operate, especially in narrow spaces such as tunnel entrances, heading heads, low coal seams and mining faces. They are products that cannot be replaced by general large-scale injection pump stations and are deeply welcomed by coal mine workers.

[0003] During the loading process of the emulsion pump assembly, the loaders need to push it to the innermost part of the truck to avoid strong collision caused by sudden braking. They only need to fix the outer end of the emulsion pump base. However, the loaders usually cannot grasp the loading distance well. If the distance is exceeded, it will cause contact and wear between the truck and the emulsion pump base. If the emulsion pump base is not completely pushed to the innermost part, there is room for movement between the emulsion pump base and the inner end of the truck. If the emulsion pump base is not installed firmly, it will move and collide. Considering the different loading and unloading habits of the loaders, it is necessary to set an anti-collision structure on the emulsion pump base. Utility Model Content

The two anti-collision components 3 are connected to the side wall of the two bottom plates 2 away from each other, and the anti-collision components 3 include an arc-shaped anti-collision strip 5 and a mounting portion 6. The mounting portion 6 is fixed to the bottom plate 2, and the two arc-shaped anti-collision strips 5 are fixed to the two mounting portions. The parts 6 are away from each other on one side wall, and the two ends of the arc-shaped anti-collision strip 5 are connected to the two ends of the mounting part 6. The outer arc surface 7 of the arc-shaped anti-collision strip 5 protrudes outward and a buffer cavity 9 is formed between the inner arc surface 8 of the arc-shaped anti-collision strip 5 and the mounting part 6. At least one buffer member 10 is arranged in the buffer cavity 9. In this embodiment, the arc-shaped anti-collision strip 5 is preferably made of rubber or silicone material, or it can be a sheet metal wrapped with rubber or silicone. The core of this application lies in the anti-collision structure of the emulsion pump base, not the structure of the emulsion pump. Therefore, the principle of the emulsion pump is not specifically explained. This is the prior art.

[0025] A bottom plate 2 and an anti-collision component 3 are respectively provided at both ends of the bottom of the middle frame 13. When a collision occurs, the arc-shaped anti-collision strip 5 is subjected to force first, which can absorb the energy generated by the collision and reduce noise. A buffer member 10 is provided in the buffer cavity 9 to prevent the arc-shaped anti-collision strip 5 from excessive deformation, extend the service life, avoid direct contact between the emulsion pump base (i.e., the frame body 1) and foreign objects during transportation, and reduce wear.

[0026] The mounting portion 6 includes a mounting plate 11 and a movable rod 12. The arc-shaped anti-collision strip 5 and the movable rod 12 are respectively arranged on both sides of the mounting plate 11. Two movable rods 12 are provided and are symmetrically arranged on the mounting plate 11. The movable rod 12 is slidably installed on the base plate 2.

[0028] A distance is left between the two bottom plates 2 and the two side ends of the middle frame 13 to form a clearance space 17 for accommodating the arc-shaped anti-collision strip 5. During transportation, the movable rod 12 is operated to move along the direction of the oblong hole 15 to push the arc-shaped anti-collision strip 5 outward. At least part of the arc-shaped anti-collision strip 5 is outside the middle frame 13. When arriving at the loading and unloading site, the arc-shaped anti-collision strip 5 can be put into the clearance space 17, that is, the arc-shaped anti-collision strip 5 is completely retracted into the middle frame 13, saving space.

[0029] The buffer member 10 includes a fixed cylinder 18, a movable member 19 and a buffer spring (not shown in the figure). The fixed cylinder 18 is connected to a side of the mounting portion 6 facing the buffer cavity 9. One end of the movable member 19 slides and is limited in the fixed cylinder 18. The buffer spring is installed in the fixed cylinder 18 and is located between the movable member 19 and the inner wall of the fixed cylinder 18. The other end of the movable member 19 is connected to the inner arc surface 8 of the arc-shaped anti-collision strip 5.

[0030] The middle frame 13 includes two side panels 20 with an I-shaped cross-section and arranged symmetrically, and a plurality of connecting members 21 arranged between the two side panels 20 and spaced apart along the length direction.

A plurality of connecting columns 24 are spaced apart and arranged between the first support plate 22 and the second support plate 23, so as to improve the overall strength of the middle frame 13 and bear the weight of the emulsion pump and the motor.

[0031] A liquid return main pipe 25 and a liquid supply main pipe 26 are arranged on both sides of the top of the middle frame 13 along the length direction. The liquid return main pipe 25 and the liquid supply main pipe 26 are provided with an interface 27 and are connected to the emulsion pump. How the liquid supply main pipe 26 and the liquid return main pipe 25 are connected to the emulsion pump is not the focus of this application. This is a prior art and therefore no specific explanation is given.

[0032] A support base 28 for installing the motor is set on the top of the middle frame 13. The support base 28 includes two support blocks 29 arranged at intervals on the middle frame 13. The two support blocks 29 are close to each other and a side wall is a support slope 30.
