Description

Technical Field

[0001] This invention relates to the field of mining equipment technology, and in particular to an intelligent integrated speed reducer for mining. Background Technology

[0002] As a core driving component of mining transportation equipment such as belt conveyors, the reliability, efficiency, and lifespan of electric drum motors directly affect the stable operation of the entire production system. The reducer, as the main transmission structure of the electric drum motor, is particularly crucial for its stable operation. In existing technologies, the integrated design that combines the drive motor and the reduction mechanism inside the drum motor has become an industry trend. Among these technologies, the combination of permanent magnet synchronous motor technology and gear reduction technology has attracted much attention due to its high power density and high efficiency.

[0003] However, this highly integrated design also brings severe thermal management challenges. There are two main heat sources inside the electric drum: one is the motor drive unit, which mainly includes the permanent magnet rotor and stator windings; the other is the gear reduction unit, which mainly includes the meshing gear pairs and their lubrication system.

[0004] The heat generated in the motor drive section mainly comes from the copper losses in the windings (which are proportional to the square of the current) and the iron losses in the core. During startup, low-speed heavy load, or impact load conditions, the motor needs to output huge torque, which causes the operating current to rise sharply. At this time, the copper losses become the dominant heat source. If heat cannot be dissipated in time, it will lead to demagnetization of the permanent magnet or damage to the insulation. The heat generated in the gear reduction section mainly comes from the friction loss and oil churning loss of the gear meshing surface. Its heat generation is roughly positively correlated with the transmitted torque. Under continuous high torque operation conditions, the temperature rise of the gear section is significant. If the oil temperature is too high, it will cause the lubricating oil viscosity to decrease and the oil film to break down, accelerating the wear of gears and bearings.

[0005] During heavy-load startup, the motor section urgently requires efficient cooling, while the gear section has relatively lower heat dissipation requirements. During long-term full-load operation, the continuous heat dissipation requirements of the gear section become crucial. Existing electric drum cooling solutions mostly employ separate cooling systems for the motor and gearbox, or use a fixed, indiscriminate cooling system to dissipate heat for both.

[0006] Therefore, it is necessary to invent an intelligent integrated speed reducer for mining to solve the above problems. Summary of the Invention

[0007] The purpose of this invention is to provide an intelligent integrated speed reducer for mining, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an intelligent integrated speed reducer for mining, comprising:

[0009] The outer shell of the drum has an internal cavity;

[0010] The drive unit fixing cover is located inside the drum housing and can rotate relative to the drum housing;

[0011] The reducer mounting cover is fixedly installed at one end of the drive unit mounting cover and located inside the drum housing;

[0012] The main heat exchange shroud is designed as a ring structure and is located outside the drive unit fixing shroud. The main heat exchange shroud is located inside the drum shell. Auxiliary heat exchange shrouds are provided on both sides of the main heat exchange shroud. Flow channels are provided on the side of the two auxiliary heat exchange shrouds closest to the main heat exchange shroud. Connectors are fixed at both ends of the two sets of flow channels. Oil pipes are provided between the two sets of connectors and the drive unit fixing shroud and the reducer fixing shroud.

[0013] The heat dissipation copper plate is designed as a ring structure and located at one end inside the drum shell. Both ends of the outer side of the heat dissipation copper plate are fixed with heat transfer fluid circulation pipes. The heat transfer fluid circulation pipes are used to form a circulation channel for the heat transfer fluid between the heat dissipation copper plate and the main heat exchange shroud. The heat dissipation copper plate is used to discharge the heat in the heat transfer fluid to the device.

[0014] Preferably, the stator is fixedly disposed inside the drive unit fixing cover;

[0015] The rotor is rotatably disposed inside the drive unit fixing cover and located inside the stator;

[0016] Planetary gear set, which is located inside the reducer housing;

[0017] A ring gear is rotatably mounted at one end of the reducer housing and fixedly connected to one end of the inner wall of the drum housing. The planetary gear set is located between the rotor and the ring gear. The rotor, the planetary gear set, and the ring gear form the driving structure of the drum housing. The planetary gear set is used to amplify the power output by the rotor and transmit it to the ring gear to drive the drum housing to rotate.

[0018] Preferably, there are two connecting pipes, each located at one end of a heat transfer fluid circulation pipe. Both connecting pipes are connected to the interior of the main heat exchange shroud. An extension pipe is provided between the heat transfer fluid circulation pipe and the connecting pipe. The extension pipe is used to connect the heat transfer fluid circulation chamber and the heat transfer fluid circulation pipe. A solenoid valve is provided between the extension pipe and the heat transfer fluid circulation pipe. The solenoid valve is used to restrict the circulation of the heat transfer fluid inside the two secondary heat exchange shrouds. The connecting pipe, the extension pipe, and the solenoid valve form two independent heat exchange systems, enabling the two secondary heat exchange shrouds to complete independent heat exchange without interference.

[0019] Preferably, a heat transfer fluid circulation pump is fixedly installed between a heat transfer fluid circulation pipe and a heat dissipation copper plate, and the heat transfer fluid circulation pump is used to drive the active circulation of the heat transfer fluid;

[0020] Two circulating oil pumps are provided and are respectively located between the drive unit fixing cover, the reducer fixing cover and the two sets of oil pipes. The drive unit fixing cover is filled with heat transfer oil and the reducer fixing cover is filled with gear oil. The circulating oil pump is used to guide the gear oil and heat transfer oil to circulate in the two sets of flow channels to achieve heat dissipation and cooling. The circulating oil pump is used to provide power to the gear oil and heat transfer oil to increase the circulation speed of the gear oil and heat transfer oil, thereby achieving the effect of accelerating heat dissipation efficiency.

[0021] Preferably, the flow channel has a serpentine structure, and the two sets of flow channels are used to guide the gear oil and heat transfer oil to circulate. The gear oil and heat transfer oil in the flow channel exchange heat with the heat transfer fluid in the main heat exchange shroud and the auxiliary heat exchange shroud. The serpentine structure design of the flow channel increases the contact area between the gear oil, heat transfer oil and heat transfer fluid, thereby improving the heat exchange efficiency.

[0022] Preferably, the heat exchange fins are provided in two sets, respectively located on both sides of the main heat exchange shroud, and the two sets of heat exchange fins are located inside the two secondary heat exchange shrouds. The heat exchange fins are used to enlarge the heat exchange channel between the main heat exchange shroud and the secondary heat exchange shrouds to improve heat exchange efficiency.

[0023] Preferably, the heat-conducting liquid sealing plate has two sets, which are respectively located on the side of the two auxiliary heat exchange covers away from the main heat exchange cover. The heat-conducting liquid sealing plate and the auxiliary heat exchange covers form a heat-conducting liquid circulation chamber. The heat-conducting liquid circulation chamber is used for the circulation of heat-conducting liquid to realize the discharge of heat inside the device to the outside.

[0024] Preferably, there are two support shafts, which are respectively fixed in the middle of the drive unit fixing cover and the reducer fixing cover. One end of each of the two support shafts is fixed with a support. The support and the support shaft are used to support and fix the device so as to facilitate the installation and use of the device.

[0025] Preferably, the heat dissipation channels are provided in multiple manner and are all located at one end of the drum shell;

[0026] The heat dissipation fins are provided in multiple and fixedly disposed on the outer side of the heat dissipation copper plate. The heat dissipation fins are used to dissipate heat from the heat transfer fluid and to increase the contact area between the heat dissipation copper plate and the air in order to improve the heat dissipation efficiency.

[0027] The technical effects and advantages of this invention are as follows:

[0028] 1. This invention integrates the motor drive unit and the gear reduction unit inside the drum shell, and uses a dual oil circuit circulation method to guide the heat transfer oil and gear oil in the motor drive unit and gear reduction unit to the heat exchange channels inside the main heat exchange shroud and the auxiliary heat exchange shroud, so as to construct two sets of heat dissipation systems to achieve independent heat dissipation of the motor drive unit and the gear reduction unit. Furthermore, by using solenoid valves to control the heat dissipation ratio of the heat transfer fluid in the two sets of heat exchange systems, priority is given to heat dissipation of the motor drive unit during heavy load start-up, and heat dissipation of the gear reduction unit is guaranteed during high-speed operation, so as to achieve intelligent control of the motor drive unit and the gear reduction unit under different working conditions, which greatly improves the reliability and life of the equipment.

[0029] 2. This invention uses a combination of a main heat exchange shroud and a secondary heat exchange shroud to dissipate heat from the motor drive unit and gear reduction unit. During operation, the main heat exchange shroud continuously dissipates heat from the motor drive unit and gear reduction unit, while the secondary heat exchange shroud adjusts in real time according to the operating conditions of the equipment to achieve intelligent control of the equipment system. Furthermore, the main and secondary heat exchange shrouds are closely arranged around the outside of the drive unit's fixed cover, forming a wrap-around three-dimensional heat dissipation channel. This improves the integration level of the equipment while ensuring heat dissipation efficiency, making the equipment adaptable to various working environments inside the mine.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] like Figures 1 to 9 As shown, the intelligent mining gear reducer provided by the present invention is essentially an intelligent mining gear reducer that integrates a motor drive unit, a gear reduction unit, and a heat dissipation system inside the drum shell 1. It employs a dual-oil-circulation method to guide the heat transfer oil and gear oil in the motor drive unit and gear reduction unit to the heat exchange channels inside the main heat exchange shroud 4 and the auxiliary heat exchange shroud 41, thereby constructing two sets of heat dissipation systems to achieve independent heat dissipation for the motor drive unit and the gear reduction unit. Furthermore, by using a solenoid valve 434 to control the heat dissipation ratio of the heat transfer fluid in the two sets of heat exchange systems, priority is given to heat dissipation of the motor drive unit during heavy-load startup, and heat dissipation of the gear reduction unit is guaranteed during high-speed operation. This achieves intelligent control of the motor drive unit and gear reduction unit under different working conditions, greatly improving the reliability and lifespan of the equipment.

[0042] In terms of specific structural installation, the structural body can be constructed according to the inventive concept of this embodiment. In this embodiment, no special limitations are imposed.

[0043] In this embodiment, an intelligent mining speed reducer includes:

[0044] The drum housing 1 has an internal cavity. As the power output part of the device, the drum housing 1 can have knurled grooves or be covered with knurled rubber sleeves on its surface to ensure stable power output.

[0045] The drive unit fixing cover 2 is located inside the drum housing 1 and can rotate relative to the drum housing 1;

[0046] The reducer mounting cover 3 is fixedly installed at one end of the drive unit mounting cover 2 and located inside the drum housing 1;

[0047] The stator 21 is fixedly disposed inside the drive unit fixing cover 2;

[0048] The rotor 22 is rotatably disposed inside the drive unit fixing cover 2 and located inside the stator 21;

[0049] Planetary gear set 31 is located inside the reducer housing 3;

[0050] The ring gear 32 is rotatably disposed at one end of the reducer fixed cover 3 and fixedly connected to one end of the inner side wall of the drum shell 1. The planetary gear set 31 is located between the rotor 22 and the ring gear 32. The rotor 22, the planetary gear set 31 and the ring gear 32 constitute the drive structure of the drum shell 1.

[0051] The main heat exchange shroud 4 is designed as an annular structure and is located outside the drive unit fixing cover 2. The main heat exchange shroud 4 is located inside the drum shell 1. Auxiliary heat exchange shrouds 41 are provided on both sides of the main heat exchange shroud 4. A flow channel 421 is provided on the side of the two auxiliary heat exchange shrouds 41 closest to the main heat exchange shroud 4. A connector 44 is fixed at both ends of the two sets of flow channels 421. An oil pipe 441 is provided between the two sets of connectors 44 and the drive unit fixing cover 2 and the reducer fixing cover 3.

[0052] The flow channel 421 has a serpentine structure. The two sets of flow channels 421 are used to guide the gear oil and heat transfer oil to circulate. The gear oil and heat transfer oil in the flow channel 421 exchange heat with the heat transfer fluid in the main heat exchange shroud 4 and the auxiliary heat exchange shroud 41. It should be noted that the amount of heat transfer oil inside the drive unit fixed cover 2 occupies one-third of the internal space of the drive unit fixed cover 2. The rotor 22 is located above the liquid surface of the heat transfer oil to avoid the heat transfer oil interfering with the rotation of the rotor 22. The heat transfer oil can be a fluorinated liquid.

[0053] The heat transfer fluid sealing plate 42 is provided in two sets and is respectively located on the side of the two auxiliary heat exchange covers 41 away from the main heat exchange cover 4. The heat transfer fluid sealing plate 42 and the auxiliary heat exchange cover 41 form a heat transfer fluid circulation chamber.

[0054] The heat dissipation copper plate 43 is designed as a ring structure and located at one end inside the drum shell 1. Both ends of the outer side of the heat dissipation copper plate 43 are fixed with heat transfer fluid circulation pipes 431. The heat transfer fluid circulation pipes 431 are used to form a circulation channel for heat transfer fluid between the heat dissipation copper plate 43 and the main heat exchange cover 4.

[0055] Two connecting pipes 432 are provided and are respectively located at one end of two heat transfer fluid circulation pipes 431. Both connecting pipes 432 are connected to the interior of the main heat exchange shroud 4. An extension pipe 433 is provided between the heat transfer fluid circulation pipe 431 and the connecting pipe 432. The extension pipe 433 is used to connect the heat transfer fluid circulation chamber and the heat transfer fluid circulation pipe 431. A solenoid valve 434 is provided between the extension pipe 433 and the heat transfer fluid circulation pipe 431. The solenoid valve 434 is used to restrict the circulation of heat transfer fluid inside the two auxiliary heat exchange shrouds 41.

[0056] A heat transfer fluid circulation pump 435 is fixedly installed between a heat transfer fluid circulation pipe 431 and a heat dissipation copper plate 43. The heat transfer fluid circulation pump 435 is used to drive the active circulation of the heat transfer fluid.

[0057] The heat exchange fins 436 are provided in two sets and are respectively located on both sides of the main heat exchange shroud 4, and the two sets of heat exchange fins 436 are respectively located inside the two auxiliary heat exchange shrouds 41.

[0058] Two circulating oil pumps 442 are provided and are respectively located between the drive unit fixed cover 2, the reducer fixed cover 3 and the two sets of oil pipes 441. The drive unit fixed cover 2 is filled with heat transfer oil and the reducer fixed cover 3 is filled with gear oil. The circulating oil pumps 442 are used to guide the gear oil and heat transfer oil to circulate in the two sets of flow channels 421 to achieve heat dissipation and cooling.

[0059] The heat dissipation channel 11 is provided in multiple ways and is located at one end of the drum shell 1. When the drum shell 1 rotates, it can also accelerate the air flow through the inner wall of the heat dissipation channel 11 to improve the heat dissipation effect of the equipment.

[0060] The heat dissipation fins 437 are provided in multiple and are fixedly disposed on the outside of the heat dissipation copper plate 43. The heat dissipation fins 437 are used to dissipate heat from the heat transfer fluid.

[0061] The support shaft 5 has two parts, which are respectively fixed in the middle of the drive unit fixing cover 2 and the reducer fixing cover 3. One end of each support shaft 5 is fixed with a support 51.

[0062] When using the intelligent mining speed reducer integrated machine of this embodiment, the support 51 is anchored as the support point of the entire device in the corresponding working area inside the mine. The drive unit fixing cover 2 and the speed reducer fixing cover 3 are fixed above the support 51 by the support shaft 5. The drum shell 1 rotates around the drive unit fixing cover 2 and the speed reducer fixing cover 3 with the support shaft 5 as the support point. When the equipment is in use, the rotor 22 and the stator 21 generate power under the action of current and magnetic field. The rotor 22 transmits the power to the planetary gear set 31. After the power is converted and strengthened by the planetary gear set 31, it is transmitted to the drum shell 1 through the ring gear 32, so that the drum shell 1 rotates around the support shaft 5, thereby driving the corresponding equipment inside the mine.

[0063] During operation, the heat transfer fluid circulation pump 435 operates continuously, driving the heat transfer fluid in the heat transfer fluid circulation pipe 431 to circulate. This causes the heat transfer fluid to circulate within the circulation channel formed by the heat transfer fluid circulation pipe 431, the heat dissipation copper plate 43, and the main heat exchange shroud 4. Simultaneously, both sets of circulating oil pumps 442 operate, drawing heat transfer oil from the drive unit fixed cover 2 and gear oil from the reducer fixed cover 3, respectively, and delivering them to the flow channels 421 within the two auxiliary heat exchange shrouds 41. The heat transfer oil and gear oil circulate along the flow channels 421. During the flow process, the gear oil and heat transfer oil exchange heat with the heat transfer fluid through the heat exchange fins 436 on the outside of the main heat exchange cover 4 to achieve cooling and temperature reduction. After cooling and temperature reduction, the gear oil and heat transfer oil flow back to the gear reducer fixed cover 3 and the drive unit fixed cover 2 respectively to achieve cooling and temperature reduction of the motor drive unit and the gear reducer transmission unit respectively. The heat transfer fluid that has absorbed heat flows through the heat transfer fluid circulation pipe 431 to the interior of the heat dissipation copper plate 43, and then the heat is discharged through the heat dissipation fins 437 on the outside of the heat dissipation copper plate 43. During this process, the motor drive unit and the gear reducer transmission unit exchange heat synchronously through the main heat exchange cover 4.

[0064] Considering that the heat generation of the motor drive unit and the reducer transmission unit are different under different operating conditions and loads, their required heat dissipation ratios are different;

[0065] When the equipment starts under high load, the motor drive unit needs to output huge torque, which causes the operating current to rise sharply. At this time, copper loss becomes the main heat source. At this time, the solenoid valve 434 in the middle of the extension pipe 433 corresponding to the drive unit fixed cover 2 is opened, and the solenoid valve 434 in the middle of the extension pipe 433 corresponding to the reducer fixed cover 3 is closed. At this time, the heat transfer fluid in the heat transfer fluid circulation pipe 431 enters the auxiliary heat exchange cover 41 corresponding to the drive unit fixed cover 2 through the extension pipe 433, and circulates along the channel between the auxiliary heat exchange cover 41 and the heat transfer fluid sealing plate 42. At this time, the heat transfer fluid cannot enter the auxiliary heat exchange cover 41 corresponding to the reducer fixed cover 3 because the solenoid valve 434 in the middle of the extension pipe 433 corresponding to the reducer fixed cover 3 is closed. At this time, while the heat transfer fluid dissipates heat to the drive unit fixed cover 2 and the reducer fixed cover 3 through the main heat exchange cover 4, it also enhances the heat dissipation of the drive unit fixed cover 2 through a set of auxiliary heat exchange covers 41, so as to improve the heat dissipation effect of the equipment on the motor drive unit in this state.

[0066] When the equipment operates at low load and high speed, the heat generated in the gear reduction section mainly comes from the friction loss and oil churning loss of the gear meshing surface. The heat generation is roughly positively correlated with the transmitted torque. Under continuous high torque operation, the temperature rise of the gear section is significant. At this time, the solenoid valve 434 in the middle of the extension pipe 433 corresponding to the drive section fixed cover 2 is closed, and the solenoid valve 434 in the middle of the extension pipe 433 corresponding to the reducer fixed cover 3 is opened. At this time, the heat transfer fluid in the heat transfer fluid circulation pipe 431 enters the section corresponding to the reducer fixed cover 3 through the extension pipe 433. Inside the secondary heat exchange cover 41, the heat transfer fluid circulates along the channel between the secondary heat exchange cover 41 and the heat transfer fluid sealing plate 42. At this time, the heat transfer fluid cannot enter the secondary heat exchange cover 41 corresponding to the drive unit fixed cover 2 because the solenoid valve 434 in the middle of the extension tube 433 corresponding to the drive unit fixed cover 2 is closed. At this time, while the heat transfer fluid dissipates heat to the drive unit fixed cover 2 and the reducer fixed cover 3 through the main heat exchange cover 4, it also enhances the heat dissipation of the drive unit fixed cover 2 through a set of secondary heat exchange covers 41, so as to improve the heat dissipation effect of the equipment on the reducer transmission part in this state.

[0067] When the equipment is running normally, the two sets of solenoid valves 434 open synchronously, and the heat transfer fluid achieves synchronous heat dissipation on the drive unit fixed cover 2 and the reducer fixed cover 3 through the main heat exchange cover 4 and the two sets of auxiliary heat exchange covers 41.

[0068] It should be noted that this embodiment only provides a drive roller layout scheme that integrates the drive unit and the reduction transmission unit, and is equipped with a corresponding heat dissipation scheme. The load and temperature monitoring of the drive roller in this embodiment adopt mature solutions in the prior art, and no restrictions are imposed on them while ensuring the normal implementation of this embodiment.

[0069] It should be further explained that the heat transfer fluid circulation pump 435, circulation oil pump 442, and solenoid valve 434 in this embodiment all adopt the corresponding structures in the prior art, and are equipped with power supply and controller. This embodiment only provides the control logic for the heat transfer fluid circulation pump 435, circulation oil pump 442, and solenoid valve 434 under different working conditions. For the combination of this control logic with the load and temperature monitoring system of the drive drum, the corresponding scheme in the prior art can be adopted. The stator 21 and rotor 22 in this embodiment both adopt the corresponding structures in the prior art. They also include permanent magnets for stabilizing the magnetic field, commutators for transmitting current, etc. No restrictions are imposed on them as long as the motor drive unit in this embodiment can generate power normally. The planetary gear set 31 and ring gear 32 in this embodiment also adopt the prior art. No restrictions are imposed on them as long as the reducer transmission unit in this embodiment can transmit power normally.

[0070] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
