DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0021] With reference to Figures 1-4 A damping device for a reduction gearbox, comprising a support box 1 and a suspension block 7 slidingly arranged inside the support box 1, the top end of the suspension block 7 is fixedly connected with the bottom end of the reduction gearbox, and a buffer liquid groove 701 is arranged in the suspension block 7.

[0022] It should be noted that the suspension block 7 has buoyancy under the action of cold water inside the support box 1, and can support the reduction gearbox. When the reduction gearbox vibrates, the suspension block 7 will also vibrate, and the vibration of the suspension block 7 will press the cold water inside the support box 1 downward. The cold water will flow into the buffer liquid groove 701 under pressure. The resistance of the cold water flowing into the buffer liquid groove 701 depends on the size of the inner diameter of the cooling liquid groove. Under the action of the buoyancy of the suspension block 7 and the resistance of the cold water flowing into the buffer liquid groove 701, the vibration of the suspension block 7 can be buffered, thereby realizing the vibration buffering function of the reduction gearbox.

[0023] A circular opening aligned with the buffer liquid groove 701 is arranged at the bottom of the reduction gearbox, a heat exchange plate 9 is slidingly arranged inside the reduction gearbox, a plurality of heat exchange copper sheets 11 are fixedly connected to the top end of the heat exchange plate 9, a heat exchange rod 8 is fixedly connected to the bottom end of the heat exchange plate 9, and the heat exchange rod 8 extends to the inside of the support box 1 through the circular opening and the buffer liquid groove 701.

[0024] It should be noted that the heat exchange copper sheets 11 can absorb heat in the air inside the reduction gearbox, and conduct the heat to the heat exchange rod 8 through the heat exchange plate 9. Heat exchange between the heat exchange rod 8 and the cold water can realize the heat dissipation function of the reduction gearbox.

[0025] Further, a rubber frame 10 is arranged around the edge of the heat exchange plate 9, and oppositely arranged power connection blocks 12 are fixedly connected to the inner wall of the reduction gearbox. Further, an alarm 5 and a power supply 6 are mounted on the outer wall of the reduction gearbox, and the alarm 5, the power supply 6 and the power connection blocks 12 are connected in series through wires.

[0026] It should be noted that the rubber frame 10 can increase the sealing between the heat exchange plate 9 and the inner wall of the reduction gearbox, so as to prevent the cold water from flowing into the upper part of the heat exchange plate 9 when pushing the heat exchange plate 9 upward, and ensure the insulation function between the cold water and the internal structure of the reduction gearbox.

[0027] Need to explain is: when the vibration of the reduction gearbox is abnormal, the rising distance of the cold water in the buffer liquid tank 701 will increase significantly, so that the cold water flows into the reduction gearbox, and then pushes the heat exchange plate 9 upwards, so that the heat exchange copper sheet 11 is placed between the grounding blocks and contacts the two side power blocks 12, so that the loop connected by the power supply 6, the power block 12 and the alarm 5 is conducted, so that the power supply 6 can power the alarm 5, so that the alarm 5 sends an alarm to remind the staff that the reduction gearbox is abnormal.

[0028] Further, the inside of the support box 1 is filled with cold water, and the inner wall of the support box 1 is fixedly connected with a cooling pipe 2, both ends of the cooling pipe 2 penetrate through the side wall of the support box 1, one end of the cooling pipe 2 is in an open state, a plurality of through holes are formed in the other end of the cooling pipe 2, further, a rotating shaft is rotatably arranged on the other end of the cooling pipe 2, a plurality of cooling fins 13 are circumferentially arranged on one end of the rotating shaft, and a driven transmission wheel 3 is fixedly connected to one end of the rotating shaft.

[0029] It is worth noting that: the driving motor drives the reduction work, which is prior art, the connection mode between the driving motor and the reduction gearbox and how to drive the reduction gearbox to work are all prior art, which will not be repeated here.

[0030] It is worth noting that: when the driving motor works, the output end will drive the synchronous wheel to rotate, and then drive the driving wheel at the center of the synchronous wheel to rotate, the driving wheel drives the driven transmission wheel 3 to rotate through the transmission belt 4, and the driven transmission wheel 3 drives the cooling fin 13 to rotate through the rotating shaft, the cooling fin 13 rotates to generate wind power, which accelerates the flow of air in the cooling pipe 2, and then accelerates the heat exchange function of the cooling pipe 2 and the cold water in the support box 1, so as to realize the heat dissipation function of the cold water in the support box 1, so that the cold water can continuously cool the reduction gearbox.

[0031] When the reduction gearbox is used, the reduction gearbox will drive the suspension block 7 to vibrate, and the suspension block 7 will extrude the cold water in the support box 1 when it vibrates, and the cold water will flow into the buffer liquid tank 701 under pressure, and the cold water will generate resistance when flowing into the buffer liquid tank 701, and the buoyancy of the suspension block 7 can buffer the vibration of the suspension block 7, and then realize the vibration buffering function of the reduction gearbox.

[0032] When the vibration of the reduction gearbox is abnormal, the vibration amplitude of the reduction gearbox will be greatly increased, so that the extrusion degree of the suspension block 7 to the cold water in the support box 1 is significantly increased, so that the rising distance of the cold water in the buffer solution tank 701 is significantly increased, and the cold water is poured into the inside of the reduction gearbox through the circular port, and the heat exchange plate 9 is extruded to move up, so that the heat exchange copper sheet 11 is placed between the grounding blocks and contacts the two side power blocks 12, so that the circuit connected by the power supply 6, the power block 12 and the alarm 5 is conducted, so that the power supply 6 can power the alarm 5, so that the alarm 5 gives an alarm to remind the staff that the vibration of the reduction gearbox is abnormal;

[0033] When the reduction gearbox works, due to the gear meshing friction, the environmental temperature and other factors, heat is generated in the inside of the reduction gearbox, the heat exchange copper sheet 11 can absorb the heat in the air in the inside of the reduction gearbox, and conduct the heat to the heat exchange rod 8 through the heat exchange plate 9, and heat exchange is carried out between the heat exchange rod 8 and the cold water, so that the heat dissipation function of the reduction gearbox is realized.

[0034] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
