Description

Technical Field

[0001] The invention belongs to the technical field of mine hoisting winches, and particularly relates to a mine hoist with an outer-rotor explosion-proof permanent magnet motor with rope discharging. Background Art

[0002] In coal mining enterprises, mine hoisting winches are essential key equipment in coal mines. They play an important role in the hoisting and transportation of personnel and materials, the dispatching of mine cars, the installation, disassembly and relocation of fully-mechanized mining equipment, and the traction of various heavy objects and equipment during the coal mining process. Common mine hoisting winches are divided into transportation dispatching winches, hoisting winches, prop-pulling winches, etc. Among them, the dispatching winch is mainly used for the development and tunneling in underground coal mines and the up-and-down hill transportation, and is also applicable to the dispatching and marshalling of mine cars in the intermediate roadway of the shaft bottom yard. It can be used for ground dispatching or other auxiliary transportation and handling work on the mine surface, metallurgical mines or construction sites; the hoisting winch is commonly used for the hoisting and transportation of materials such as coal, gangue, and equipment in inclined roadways or vertical shafts, and has a large traction power and good safety performance; the prop-pulling winch, also known as the slow winch, is mainly used for the removal and recovery of face supports and the relocation of underground hydraulic supports. The main performance of the prop-pulling winch is large traction force and slow traction speed.

[0003] In mine production, the haulage winch in the mining area is mainly responsible for the transportation task of equipment and materials in the mining area of the underground coal mine. With the improvement of the mine mechanization level, fully-mechanized mining and tunneling equipment and supports have been widely used in the underground, and more and more large mechanical equipment has entered the mining area. Therefore, the hydraulic braking device of the hoisting winch is a very important equipment. In existing mines, in order to meet the requirements of transporting large and heavy mining and excavation equipment on the up-and-down hills in the main mining area, in recent years, high-power dispatching winches (motor power is 55 - 90 kw) have been used for the up-and-down hill hoisting winches in the main mining area of the underground coal mine. Although the lifting capacity of this dispatching winch meets the requirements, it is found in use that the power of the brake oil pump in the original winch braking system is too small (the braking force is 180 N), and it is a single-sided brake. The brake uses a band friction brake pad, and the torque is transmitted by the brake rod. The braking is carried out by the frictional force generated between the brake pad and the brake wheel. Due to the constraint of the braking force on the brake oil pump, when lifting or lowering heavy objects such as fully-mechanized mining equipment (such as the weight of the hydraulic support reaches 11 t), the original electromagnetic brake of the winch cannot meet the braking requirements, and it is also very difficult for the manual brake to meet the requirements. Especially when the winch suddenly loses power or stops suddenly, the braking system of the winch cannot achieve reliable braking, which is likely to cause major accidents such as runaway, bringing difficulties to the transportation of large equipment in the mining area. Due to insufficient braking torque, many potential safety hazards are caused. Summary of the Invention

[0058] As a further preferred solution, a bell mouth 112 is provided at the end of the stator shaft 101, which plays an explosion-proof role.

[0059] In this embodiment, specifically, the permanent magnets are fixed on the inner wall of the rotor housing and are circumferentially distributed. The driving sprocket and the sprocket connecting shaft are connected by 4 keys. The baffle is connected to the end of the sprocket connecting shaft by bolts and axially limits the sprocket with the shoulder on the sprocket connecting shaft.

A bearing is installed between the rotor bearing housing and the stator, and the fit between the rotor bearing housing and the stator meets the explosion-proof requirements specified in GB3836.

[0060] Embodiment 3:

[0061] On the basis of the above embodiments, further, as Figure 6 , Figure 7 shown, the reciprocating screw rope discharging device 2 at least includes a mounting seat 201, a reciprocating screw rod 203, a rope discharging bracket 206, a wire rope fixing wheel 208 and a wire rope. The mounting seat 201 is fixed on the base 4. The reciprocating screw rod 203 is arranged parallel to the stator shaft 101, and both ends of the reciprocating screw rod 203 are respectively fixed on the mounting seat 201 through two mutually parallel screw rod bearing seats 202. Both ends of the reciprocating screw rod 203 respectively extend out of the outside of the screw rod bearing seats 202, and a driven sprocket 205 is provided on the part of the reciprocating screw rod 203 extending out of the outside of the screw rod bearing seats 202. The driven sprocket 205 is connected to the driving sprocket 103 by a chain. Two mutually parallel guide rods 204 symmetrically distributed on both sides of the reciprocating screw rod 203 are arranged between the two screw rod bearing seats 202. The rope discharging bracket 206 is installed on the guide rods 204 through guide blocks 207, and the rope discharging bracket 206 can slide axially along the reciprocating screw rod 203. Further, four wire rope fixing wheels 208 are provided. Every two of the four wire rope fixing wheels 208 are fixed at both ends of the rope discharging bracket 206. The two wire rope fixing wheels 208 are arranged side by side, and an annular groove is formed at their connection. One end of the wire rope is fixed on the rotor housing 105, and the other end of the wire rope passes through the annular groove between the two wire rope fixing wheels 208 at both ends of the rope discharging bracket 206 in sequence and is connected to the mine car.

[0062] As a further preferred solution, the driven sprocket 205 is connected to the reciprocating screw rod 203 by a key.

[0063] As a further preferred solution, the reciprocating screw 203 is provided with thread grooves with the same pitch and opposite rotation directions. Figure 8 As shown, the reciprocating screw rope guide 2 also includes a slider 209. The lower end of the slider 209 is inserted into the spiral groove of the reciprocating screw 203. The upper end of the slider 209 is connected to the rope guide bracket 206 via a shaft sleeve. As the reciprocating screw 203 rotates, the slider 209 drives the entire rope guide bracket 206 to move along the axis of the reciprocating screw 203. When the slider 209 moves to the end of the reciprocating screw 203, it slides into the groove of the other rotation direction and begins to move in the opposite direction, thereby achieving reciprocating motion of the slider 209 on the reciprocating screw 203 while the reciprocating screw 203 rotates in the same direction. The slider 209 drives the rope guide bracket 206, which then reciprocates while clamping the wire rope.

[0064] The operating principle is as follows: When the dispatching winch needs to lift a mine car, the control device applies positive current to the stator winding, causing the outer rotor to rotate, driving the driving sprocket. The driving and driven sprockets are connected by a double chain. This in turn drives the driven sprocket. The driven sprocket then rotates the reciprocating screw, which in turn drives the wire rope in reciprocating motion. The wire rope diameter, the pitch of the reciprocating screw, and the number of teeth on the driving and driven sprockets are carefully matched to ensure that the wire rope moves along the motor shaft by one wire rope diameter per rotation of the rotor housing, thus neatly wrapping the wire rope around the motor housing. When one layer of wire rope is wound, the reciprocating screw reverses the winding process and winds the second layer around the motor housing. This process continues, completing the third, fourth, and so on, winding the wire rope, lifting the mine car and completing the load.

[0065] When the dispatching winch needs to lower the mine car, the control device passes reverse current to the stator winding, the outer rotor rotates in the opposite direction, and the steel wire rope wrapped around the outer rotor motor casing is unwound layer by layer to lower the mine car.

[0066] Furthermore, the control device contains a frequency converter that can easily adjust the speed of the motor to control the speed of lifting or lowering the mine car. This saves the reducer part of the traditional winch.

[0067] Furthermore, if Figure 2 As shown, a hydraulic brake 3 is also mounted on the base 4, and the hydraulic brake 3 is in contact with or out of contact with the rotor housing 105. If the winch needs to stop midway, the hydraulic oil is used to support the hydraulic brake and the reel (rotor housing 105) is rotated by contact friction.

[0068] In summary, the present invention connects the rope arranging device to the winch through chain drive, and with the structural design of the reciprocating lead screw, selects an appropriate transmission ratio through calculation to ensure that the steel wire rope is arranged orderly and neatly on the drum of the winch. The mine winch of the outer-rotor explosion-proof permanent magnet motor type with rope arranging provided by the present invention is an electric, single-steel wire rope traction, multi-layer winding type dispatching winch, which has the advantages of simple structure, small overall dimension and being conducive to arrangement in a narrow space.

[0069] The preferred embodiments of the present invention have been specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art can also make various equivalent variations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
