Description

Technical Field

[0001] This utility model belongs to the field of mining equipment, and in particular relates to an emulsion pump base device. Background Technology

[0002] Emulsion pumps are used in coal mining operations. To facilitate movement and installation within the mine, they are typically mounted on a support device. The support device consists of an emulsion pump chassis and a chassis vehicle supporting the chassis. The chassis vehicle includes a frame and a wheel assembly mounted on the bottom of the frame. The wheel assembly includes an axle and track wheels at both ends of the axle. Bearings are installed in the track wheels. A wheel assembly mounting beam is located at the bottom of the frame, and axle mounting seats are mounted on the wheel assembly mounting beam. The axles are fixed to the axle mounting seats. Because the track wheels are very close to the wheel assembly mounting beam, a clearance groove is usually created in the beam to allow the upper edge of the track wheels to protrude. To facilitate wheel assembly installation, a larger clearance groove is usually required, but this reduces the strength of the wheel assembly mounting beam. However, if the clearance groove is too small, the installation precision requirements for the wheel assembly become extremely high, making installation very difficult and easily leading to friction between the track wheels and the clearance groove.

[0003] The technical problem to be solved by this utility model is to provide a high-precision emulsion pump base device.

[0004] To solve the above problems, the technical solution adopted by this utility model includes: a frame and a wheel assembly installed at the bottom of the frame. The wheel assembly includes an axle and track wheels at both ends of the axle. The track wheels are provided with bearings. The bottom of the frame is provided with a wheel assembly mounting beam. The wheel assembly mounting beam is provided with an axle mounting seat. The axle is fixed on the axle mounting seat. The wheel assembly mounting beam is characterized in that: track wheel clearance grooves are provided on both sides of the wheel assembly mounting beam, and a detachable track wheel positioning block is provided in the track wheel clearance groove. The track wheel positioning block is provided with a first positioning groove that is adapted to the positioning wheel edge of the track wheel.

[0005] The high-precision emulsion pump base support device is characterized in that: the track wheel positioning block is provided with a rotating shaft at both ends, and the end of the rotating shaft is provided with an eccentric connecting plate that is connected to the track wheel clearance groove.

[0006] The high-precision emulsion pump base device is characterized in that: a positioning flange is provided in the middle of the inner wall of the track wheel, and bearings are provided on both sides of the positioning flange.

[0007] The high-precision emulsion pump base device is characterized in that: the outer end of the track wheel is provided with an end cover, and the rear end of the end cover is provided with an oil storage chamber.

[0008] The high-precision emulsion pump base device is characterized in that: a fastening nut is connected to the outer end of the wheel axle, a second positioning groove arranged in a circle is provided at the rear end of the fastening nut, and a positioning pin is provided at the outer end of the wheel axle, with both ends of the positioning pin placed in the second positioning groove.

[0009] The advantages of this high-precision emulsion pump base device are as follows: when the positioning wheel edge of the track wheel is embedded into the positioning groove of the track wheel positioning block, the track wheel is located exactly in the center of the track wheel clearance groove, and then the wheel axle is fixed, which can greatly improve the installation accuracy and make the installation very convenient.

[0010] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

[0016] Reference Figure 1-5 As shown, the high-precision emulsion pump support device of this utility model includes a frame 1 and a wheel set 2 mounted on the bottom of the frame 1. The wheel set 2 includes an axle 3 and track wheels 4 located at both ends of the axle 3, with bearings 5 ​​installed inside the track wheels 4. A wheel set mounting beam 6 is provided at the bottom of the frame 1, and an axle mounting seat 7 is provided on the wheel set mounting beam 6, with the axle 3 fixed on the axle mounting seat 7. Track wheel clearance grooves 8 are provided on both sides of the wheel set mounting beam 6, and detachable track wheel positioning blocks 9 are provided in the track wheel clearance grooves 8. The track wheel positioning blocks 9 are provided with a first positioning groove 10 that corresponds to the positioning wheel edge 19 of the track wheel 4. The track wheel positioning blocks 9 are typically made of plastic.

[0017] Preferably, the track wheel positioning block 9 has rotating shafts 11 at both ends, and an eccentric connecting plate 12 connected to the track wheel clearance groove 8 at the end of each rotating shaft 11. When the track wheel positioning block 9 is inserted into the track wheel clearance groove 8, rotating the rotating shaft 11 connects the eccentric connecting plate 12 to the track wheel clearance groove 8, thereby fixing the track wheel positioning block 9. After the wheel axle 3 is installed, reversing the eccentric connecting plate 12 allows the track wheel positioning block 9 to be removed.

[0018] Preferably, the inner wall of the track wheel 4 is provided with a positioning flange 13 in the middle, and bearings 5 ​​are provided on both sides of the positioning flange 13. By setting a double bearing structure, the stability and strength of the track wheel 4 can be greatly enhanced.
