Technical Field
[0001] The present invention belongs to the technical field of belt conveyor cooling, and particularly relates to a movable belt conveyor reducer cooling device. Background Art
[0002] The movable belt conveyor reducer is a part of the driving device of the movable belt conveyor, and provides low-speed and high-torque power for the belt conveyor. At present, the movable belt conveyor reducer is a fully exposed device (see Figure 1 ), which includes a reducer housing, a high-speed transmission shaft, a low-speed output shaft, etc. When the outdoor temperature exceeds 45°C, the ambient temperature approaches 80°C. Even if high-viscosity gear oil for summer is used, it is impossible to lubricate and cool the overheated components of the reducer. This often leads to the situation that the equipment cannot be started normally due to high temperature, restricting the normal outdoor use of the movable belt conveyor in summer in the northwest. Summary of the Invention

The rectangular air flow channel is arranged along the axial direction of the reducer output shaft, and the triangular air guide channels are communicated with the rectangular air flow channel; cooling copper tubes are tied to the reducer housing, and the installation position of the first cooling copper tube is below the center of the tooth surface, and a total of three are tied; one end of the cooling copper tube is connected to a compressor, and the compressor is connected to a heat exchanger and a liquid storage tank in sequence through copper tubes and then connected back to the other end of the cooling copper tube to form a closed system, and a refrigerant is provided in the liquid storage tank.
[0005] In the above solution, the heat preservation board is an aluminum foil composite silicate cold insulation board.
[0006] In the above solution, the heat preservation board also has an avoidance space adapted to the outer contour of the reducer, and the thickness of the heat preservation board wrapped outside the reducer output shaft is 2 times the thickness of other parts of the heat preservation board.
[0007] In the above solution, the frame is a cuboid frame with one open side formed by a front end face frame, a rear end face frame, and a second adjustment beam, a first adjustment beam, and a third adjustment beam that connect the two. The front end face frame and the rear end face frame are both day-shaped plane frames, and the day-shaped plane frames are respectively formed by an upper end face beam, a left frame beam, a lower end face beam, and a right frame beam.
[0008] In the above scheme, the base of the reducer is installed on the first adjustment beam, the tail connecting beam of the reducer is installed on the lower end beam of the I-shaped plane frame, and the upper connecting beam of the reducer is installed on the upper end beam of the I-shaped plane frame. The beneficial effects of the present invention are as follows: a movable belt conveyor reducer cooling device includes a frame installed outside the reducer, and an insulation board is arranged inside the frame; the insulation board is integrally formed with a plurality of triangular air guide channels with smooth inner walls and smooth rectangular air flow channels connected thereto, and the cooling copper tube is tied to the reducer housing, and the first cooling copper tube is installed at a position slightly below the center of the tooth surface, and a total of three ties are tied; one end of the cooling copper tube is connected to the compressor, and the compressor is connected to the heat exchanger and the liquid storage tank in sequence through the copper tube and then connected back to the other end of the cooling copper tube, forming a closed cooling system.

The front face frame and the rear face frame are both s-shaped plane frames, which are bolted to the three adjustment beams through positioning holes 12. The s-shaped plane frame is composed of an upper end face beam 7, a left frame beam 1, a lower end face beam 3, and a right frame beam 5. The reducer 8 is installed in the rectangular parallelepiped frame, and the base of the reducer 8 is installed on the first adjustment beam 10. Bolts are inserted into the adjustment holes on the first connecting beam 10 and the bolt holes reserved on the reducer base, and the first adjustment beam 10 is tightened and fixed by bolts. The tail connecting beam of the reducer is installed on the lower end face beam 3 of the s-shaped plane frame, and the upper connecting beam of the reducer is installed on the upper end face beam 7 on the s-shaped plane frame. Bolts are inserted into the positioning holes of the s-shaped plane frame and the adjustment holes of the first adjustment beam 10 and then fixed.
[0014] In this embodiment, an aluminum foil composite silicate insulation board 6 is installed between the rectangular frame and the reducer housing, and the second adjustment beam 9 and the first adjustment beam 10 are adjusted according to the shape of the reducer 8 and the reserved space for the insulation material. The front and rear end face sizes are adjusted by the clamping loose bolts. After adjustment, insert the positioning pins at the adjustment holes and tighten the connecting bolts. The insulation material installation method: the aluminum foil composite silicate insulation board 6 is cut according to the left, right, top and rear faces of the reducer, and the irregular parts of the reducer are filled with the aluminum foil composite silicate insulation board 6 to form the four faces of the insulation structure. The fan side and the bottom of the input shaft are not made into insulation structure. The insulation structure is installed on the metal frames such as the front face frame and the rear face frame with flexible strips respectively; the bottom where the heating and insulation device is connected to the reducer and the input shaft fan are sealed with self-adhesive insulation materials.
[0015] In this embodiment, each cross-section frame is a s-shaped plane frame, and the s-shaped plane frame is connected by an upper adjustment beam and a lower adjustment beam, and the lower connection adjustment beam is fixed on the reducer base. The reducer is installed in the rectangular frame in the following way: the lower connection beam is installed on the reducer base, and bolts are inserted into the adjustment holes of the lower connection beam and the reserved bolt holes of the reducer base, and the bolts are tightened to fix the lower connection beam; the s-shaped plane frames on both sides are installed on the lower connection beam by bolt connection; the reducer tail connection beam and the upper connection beam are installed on the plane frame, and the bolts are inserted into the positioning holes of the plane frame and the adjustment holes of the connection beam, and the bolts are tightened; the connection beam is adjusted according to the shape of the reducer and the reserved space for the cold insulation material; after adjustment, the positioning pins are inserted into the adjustment holes, and each connection bolt is tightened.
[0016] In this embodiment, an aluminum foil composite silicate insulation board 6 is installed between the rectangular frame and the housing of the reducer 8 as a cold-insulating structural layer. The shape of the aluminum foil composite silicate insulation board 6 is adapted to the housing of the reducer 8. A plurality of triangular air-guiding channels 61 with smooth inner walls and rectangular air-flow channels 62 with smooth inner walls are integrally formed on the aluminum foil composite silicate insulation board 6 of this embodiment, wherein the triangular air-guiding channels 61 are distributed over the entire surface of the cold-insulating structural layer, and the rectangular air-flow channels 62 are arranged along the axial direction of the output shaft of the reducer, and the triangular air-guiding channels 61 are connected to the rectangular air-flow channels 62.

The cold-insulating structural layer is also adapted to the housing of the reducer 8, and the part thereof in contact with the housing of the reducer 8 is bonded to the surface of the housing of the reducer 8 by shearing. The thickness of the wrapped part 63 wrapped outside the output shaft of the reducer 8 is twice that of the cold-insulating structural layer, so that the density of the insulation layer outside the output shaft of the reducer 8 is increased, which is more conducive to temperature preservation.
