DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] It should be noted that the directional words such as "upper" and "lower" mentioned below are defined based on the drawings in the specification.

[0030] The core of the present invention is to provide a driving structure of an overhead passenger device, which uses a permanent magnet drum motor 2 to directly drive a driving wheel 3, has a compact structure, occupies a small space, and has a high transmission efficiency. By setting a cavity, the permanent magnet 221 of the permanent magnet drum motor 2 is prevented from being directly subjected to force, thereby preventing the permanent magnet 221 from being deformed. Another core of the present invention is to provide an overhead passenger device including the driving structure of the overhead passenger device, which has a simple structure, light weight, occupies a small space, and has high reliability.

[0031] Please refer to Figure 1 and Figure 2 A driving structure of an overhead passenger device is provided on a frame 1.

[0032] Specifically, the driving structure includes a permanent magnet drum motor 2 arranged on a frame 1, and a driving wheel 3 is arranged on the outer periphery of the permanent magnet drum motor 2. The permanent magnet drum motor 2 is used to directly drive the driving wheel 3, and the intermediate transmission mechanism is omitted, and the multi-stage transmission is simplified into a single direct drive transmission, thereby reducing the energy loss in the intermediate transmission process, and the transmission efficiency is high. The entire driving device has a compact structure, occupies a small space, and has higher safety and reliability. An annular groove is arranged on the outer cylinder wall of the permanent magnet drum motor 2, and the driving wheel 3 is arranged corresponding to the annular groove to form an annular cavity 4. When the overhead passenger device is running, the wire rope will generate radial tension on the permanent magnet drum motor 2. By setting the annular cavity 4, the permanent magnet 221 on the inner side of the permanent magnet drum motor 2 can be prevented from being deformed by force.

[0033] The driving structure of the overhead passenger device arranged in the above manner, by arranging an integrated structure in which the permanent magnet drum motor 2 directly drives the driving wheel 3, replaces the traditional "three-phase asynchronous motor + reducer + driving wheel 3", omits the intermediate transmission mechanism, simplifies the multi-stage transmission into a single direct drive transmission, reduces the energy loss in the intermediate transmission process, has high transmission efficiency, and has a compact overall structure, occupies a small space, has higher safety and reliability, and ultimately achieves the goal of high efficiency, energy saving and maintenance-free of the driving structure of the overhead passenger device.

[0034] Please refer to Figure 3 In one embodiment, a disc brake 5 for braking the driving wheel 3 is provided on the frame 1. In this case, the driving wheel 3 can be used as a brake disc 6, and one brake disc 6 can be saved. The driving wheel 3 is directly braked by the disc brake 5 to stop the permanent magnet drum motor 2 from rotating.

[0035] In the above case, at least two disc brakes 5 are provided, and at least two disc brakes 5 are connected to the hydraulic drive device. The disc brake 5 mainly relies on the hydraulic drive device to drive the brake caliper to achieve braking. In this case, the disc brake 5 includes a brake caliper, which is arranged around the outer periphery of the driving wheel 3. The brake caliper includes two clamps, and the ends of the clamps away from the driving wheel 3 are connected through the hydraulic drive device. The hydraulic drive device is used to drive the clamps to clamp or release the driving wheel 3. The hydraulic drive device is connected to the oil distribution pump through an oil pipe, and the oil distribution pump is connected to the oil source.

[0036] It should be noted that, in the initial state, the brake caliper does not contact the brake disc 6 or the drive wheel 3 .

[0037] When in use, the hydraulic oil provided by the oil source is distributed to the two corresponding hydraulic drive devices through the oil distribution pump to drive the hydraulic drive devices to contract, driving the two brake calipers to move towards each other until the drive wheel 3 is clamped, generating a friction torque to prevent the drive wheel 3 from rotating, thereby achieving braking of the drive wheel 3.

[0038] It can be understood that the disc brake 5 is arranged on the side that does not interfere with the passengers of the chairlift, that is, the side close to the frame 1, and the disc brake 5 is at least two sets, one set for braking during normal operation and the other set for emergency safety braking.

[0039] Compared with the prior art, the push rod disc brake 5 at the high-speed end of the traditional driving device is cancelled, and two sets of disc brakes 5 are used, which have a large braking torque and ensure controllable braking when transporting heavy loads.

[0040] Please refer to Figure 4 In another embodiment, the disc brake 5 includes a brake disc 6 and a brake caliper, the brake disc 6 is arranged on the outer periphery of the permanent magnet drum motor 2, the brake caliper is arranged around the outer periphery of the brake disc 6, and the brake disc 6 is arranged at one end away from the driving wheel 3, the brake caliper includes two clamps, and the end of the clamp away from the brake disc 6 is connected through a hydraulic drive device, the hydraulic drive device is used to drive the clamp to clamp or release the brake disc 6, the hydraulic drive device is connected to the oil distribution pump through an oil pipe, and the oil distribution pump is connected to the oil source.

[0041] In this case, the driving wheel 3 and the brake disc 6 are separate structures. The brake disc 6 is arranged on the outer periphery of the permanent magnet drum motor 2, and the brake disc 6 is braked by the disc brake 5 to stop the rotation of the permanent magnet drum motor 2. When in use, the hydraulic oil provided by the oil source is distributed to the two corresponding hydraulic drive devices through the oil distribution pump to drive the hydraulic drive device to contract, drive the two brake calipers to move in a direction close to each other, until the brake disc 6 is clamped, and a friction torque is generated to prevent the brake disc 6 from rotating, thereby achieving braking of the brake disc 6.

[0042] The diameter of the brake disc 6 should be as large as possible. At this time, the effective radius of the brake disc 6 is increased, which can reduce the clamping force of the brake caliper. The thickness of the brake disc 6 affects the mass of the brake disc 6 and the temperature rise during operation. In order to reduce the mass, the thickness of the brake disc 6 should not be too large; in order to reduce the temperature, the thickness of the brake disc 6 should not be too small. The brake disc 6 can be made solid, or a ventilation channel can be cast in the middle of the brake disc 6 for heat dissipation and ventilation. Generally, the thickness of the solid brake disc 6 can be 10-20mm, and the thickness of the ventilated brake disc 6 can be 20-50mm, and the most commonly used is 20-30mm. In emergency braking under high-speed movement, the brake disc 6 will form thermal deformation and produce tremors. In order to improve the heat dissipation performance of the friction surface of the brake disc 6, most of the brake discs 6 are made into ventilated brake discs 6 with a hollow in the middle, which can reduce the temperature of the brake disc 6 by 20%-30%.

[0043] The working surface of the disc brake 5 is flat and heat is transferred on both sides. The disc is easy to cool when rotating, and is not easy to deform greatly. The braking performance is relatively stable. After long-term use, the brake disc expands due to high temperature, which enhances the braking effect. The disc brake 5 has a simple structure, is easy to maintain, and can easily achieve automatic adjustment of the brake clearance.

[0044] Among them, the brake disc 6 can be directly welded to the permanent magnet drum motor 2, or a connecting seat can be set on the permanent magnet drum motor 2 to achieve effective connection between the brake disc 6 and the permanent magnet drum motor 2. In practical applications, it is not limited to the above two connection methods. As long as the connection method can achieve the above technical effects, it is within the protection scope of this application.

[0045] Please refer to Figure 2 The permanent magnet drum motor 2 includes a coaxially arranged stator structure 21 and a rotor structure 22. The stator structure 21 is arranged inside the rotor structure 22, and the stator structure 21 is arranged on the frame 1. The driving wheel 3 is arranged on the outer periphery of the rotor structure 22. The stator structure 21 is externally connected to a power supply. When the stator structure 21 is energized, an electromagnetic field is generated to drive the rotor structure 22 to rotate, thereby driving the driving wheel 3 to rotate synchronously.

[0046] It should be noted that the stator structure 21 is fixed to the frame 1, and the rotor structure 22 is arranged on the outer periphery of the stator structure 21. The stator structure 21 is energized to generate an electromagnetic field, thereby driving the rotor structure 22 to rotate along its own axial direction, and at the same time driving the driving wheel 3 on the rotor structure 22 to rotate synchronously. When a brake disc 6 is arranged on the outer periphery of the rotor structure 22, the brake disc 6 can be driven to rotate synchronously through the rotation of the rotor structure 22.

[0047] In the above embodiment, the stator structure 21 includes a coaxially arranged fixed shaft 211, a stator punching sheet 212 and a stator winding 213. Both ends of the fixed shaft 211 are arranged on the frame 1. The stator punching sheet 212 is connected to the fixed shaft 211 through a bracket assembly. The bracket assembly includes a coaxially arranged first bracket and a second bracket. The first bracket and the second bracket are connected through a stator bracket 214. The first bracket is arranged on the outer periphery of the fixed shaft 211. The stator bracket 214 is arranged along the axial direction of the fixed shaft 211, and the stator bracket 214 is radially arranged around the outer periphery of the fixed shaft 211. The stator winding 213 is arranged in the slot of the stator punching sheet 212.

[0048] It can be understood that the fixed shaft 211 is a vertical double-outlet shaft structure, and the two ends of the fixed shaft 211 are respectively installed and fixed on the upper and lower parts of the frame 1. The fixed shaft 211 is connected to the first bracket, and the stator punching sheet 212 is arranged on the outer wall of the second bracket. The stator winding 213 is arranged in the slotted stator punching sheet 212. The stator winding 213 is connected to electricity to generate an electromagnetic field to drive the rotor structure 22 to rotate.

[0049] As a preferred embodiment, a pipe for introducing coolant is provided on the outer periphery of the second bracket, a water inlet and a water outlet are provided at the first end of the fixed shaft 211, and a water inlet channel 7 and a water outlet channel 8 connected to the pipe are also provided at the first end, the water inlet is connected to the water inlet channel 7, and the water outlet is connected to the water outlet channel 8.

[0050] It should be noted that a water inlet and a water outlet are axially arranged on the end face of the first end of the fixed shaft 211, and the coolant flows into the water inlet channel 7 from the water inlet, passes through the pipe on the periphery of the second bracket, flows through the water outlet channel 8, and flows out from the water outlet. The water inlet, the water outlet, the water inlet channel 7, the water outlet channel 8 and the pipe on the periphery of the second bracket are connected in series to form a cooling cavity to cool and dissipate heat from the stator winding 213.

[0051] In the above case, an electrical junction box 9 is provided at the second end of the fixed shaft 211, and the electrical junction box 9 is detachably provided on the fixed shaft 211. A wiring channel is also provided at the second end of the fixed shaft 211, and the wiring channel includes a first wiring through hole extending along the axial direction of the fixed shaft 211, and also includes a second wiring through hole connected to the first wiring through hole. The first wiring through hole is provided in the middle of the fixed shaft 211, and the outlet end of the second wiring through hole is provided in the circumference of the fixed shaft 211. The electrical junction box 9 is electrically connected to the stator winding 213 through a cable.

[0052] It can be understood that a first wiring through hole connected to the electrical junction box 9 is axially opened on the end face of the second end of the fixed shaft 211, and a second wiring through hole connected to the first wiring through hole is also circumferentially opened on the second end of the fixed shaft 211. The electrical junction box 9 is fixed on the end face of the second end of the fixed shaft 211, and the electrical junction box 9 and the stator winding 213 are connected by cables. The cables are laid in the first wiring through hole and the second wiring through hole to realize the electrical connection between the electrical junction box 9 and the stator winding 213, so that the stator winding 213 can generate an electromagnetic field when energized to drive the rotor structure 22 to rotate.

[0053] In the above embodiment, the rotor structure 22 includes a coaxially arranged permanent magnet 221 and an outer drum 222, the permanent magnet 221 is arranged on the inner wall of the outer drum 222, end covers 223 are arranged at both ends of the outer drum 222, and a mounting hole is arranged in the middle of the end cover 223 to mount the fixed shaft 211 on the end cover 223, the end cover 223 and the fixed shaft 211 are rotatably connected through a bearing, and a closed chamber is formed between the end cover 223, the outer drum 222, and the fixed shaft 211.

[0054] It should be noted that the rotor structure 22 includes an outer drum 222, a permanent magnet 221 and an end cover 223. An annular groove is provided at a position on the outer wall of the outer drum 222 corresponding to the driving wheel 3 to form an annular cavity 4. When the overhead passenger device is in operation, the steel wire rope will generate radial tension. The annular cavity 4 can prevent the permanent magnet 221 on the inner side of the outer drum 222 from being deformed by force. Among them, the end cover 223 is rotatably connected to the fixed shaft 211 through a bearing. When the stator winding 213 is energized, an electromagnetic field is generated to drive the permanent magnet 221 to drive the outer drum 222, the end cover 223 and the driving wheel 3 to rotate synchronously.

[0055] The driving wheel 3 can be directly welded to the outer drum 222 to form an integrated structure, or can be set as a split structure for easy disassembly, with a disc welded on the outer drum 222, with a thread hole punched on the disc, and the driving wheel 3 is fixed to the disc by bolts. In practical applications, the connection methods of the driving wheel 3 and the outer drum 222 are not limited to the above two.

[0056] Furthermore, the cross-sectional shape of the frame 1 in the installation height direction is C-shaped. The frame 1 includes an upper top plate, a lower bottom plate and a connecting support plate for connecting the upper top plate and the lower bottom plate. The connecting support plate is connected to the upper top plate and the lower bottom plate by bolts. Reinforcing plates are provided between the connecting support plate and the upper top plate and the lower bottom plate. The upper top plate and the lower bottom plate are provided with through holes for installing the fixed shaft 211.

[0057] The frame 11 is erected in a C shape on the basic structure of the mine tunnel, and the supporting strength of the frame 1 on the side close to the driving wheel 3 is greater than the supporting strength of the frame 1 on the side away from the driving wheel 3, which can effectively improve the stress condition of the outer drum 222 and prevent the outer drum 222 from being cantilevered, thereby ensuring that the air gap magnetic field of the motor is stable after the outer drum 222 is subjected to stress.

[0058] The frame 1 may be made of H-shaped steel or I-shaped steel.

[0059] In summary, the driving structure of the overhead passenger device provided by the present invention has an integrated design of the rotor structure 22 and the driving wheel 3 in terms of transmission efficiency, which reduces the intermediate transmission process, reduces mechanical loss and failure rate, and improves transmission efficiency. In terms of driving performance, a disc brake 5 is adopted, which has a large braking torque to ensure controllable braking when transporting heavy loads, and the permanent magnet drum motor 2 can output a large torque at low speed, has a strong overload capacity, and has higher safety and reliability.
