Description

Technical Field

[0001] The invention relates to the technical field of monorail cranes for auxiliary transportation in underground coal mines, and in particular to a distributed drive assembly system of a permanent magnet monorail crane. Background Art

[0002] The monorail lifting support transportation system has become one of the most important modes of transportation in coal mine production abroad. It has extremely obvious advantages: it can make more effective use of the tunnel section and is not affected by floor factors; it has considerable climbing ability and can adapt to the ups and downs of the tunnel; it has a small curve radius, fast speed, flexibility, and can enter multiple branch roads, which can realize one-stop non-transfer transportation, and its work efficiency is significantly better than other transportation equipment; it has low initial investment and low maintenance cost.

[0003] The core part of the monorail hoisting support transportation system is the monorail crane locomotive (monorail crane for short). According to the different power sources, monorail cranes can be divided into explosion-proof diesel engine monorail cranes and explosion-proof battery monorail cranes. Monorail cranes powered by diesel engines have high fuel consumption and high costs. The use of diesel poses a threat to the underground production safety environment, and produces exhaust pollution and noise pollution, affecting the production environment of the mine. The explosion-proof battery monorail crane uses electricity, the power source is continuous and stable, the operating distance is long, the safety performance is good, and it is energy-saving, environmentally friendly and pollution-free.

[0004] The electric traction monorail crane with battery power supply developed in the prior art has the problem of no pollution when used underground, but it also has the problems of small capacity of power supply, low voltage, low efficiency of motor and transmission system, etc. Due to insufficient power of the battery, the monorail crane cannot operate on a large slope (more than 16 degrees), and can only operate with light load on a small slope, so the transportation capacity and cruising range are affected, and the use is limited; and because the traditional power source is only a single distribution, the power distribution is uneven, and it cannot provide balanced kinetic energy for the whole vehicle. The traditional vehicle control system causes uneven power distribution, and the efficiency and timeliness of controlling vehicle movement are not high. When the hydraulic cylinder fails or the power is cut off during the operation of the monorail hoisting bracket, the traditional monorail hoisting bracket will suddenly slide down on the slope, and the monorail hoisting brackets are prone to collide with each other and cause accidents.

[0005] Therefore, it is necessary to provide a new permanent magnet monorail crane distributed drive assembly system to solve the above technical problems. Summary of the invention

[0006] The technical problem solved by the present invention is to provide a permanent magnet monorail crane distributed drive assembly system with strong safety, which can effectively improve the operating distance and load capacity of the monorail crane, ensure the balance of power distribution, and improve the overall safety performance of the vehicle.

[0057] like Figure 3 and Figure 4As shown, a limiting mechanism 7 is provided, wherein the limiting mechanism 7 is connected to the side wall of the monorail crane walking device 5 and the supporting mechanism 4; the limiting mechanism 7 comprises a friction wheel 71, a fixed shaft 72, a fixed rod 73, a limiting plate 74, a second spring 75, a limiting rod 76 and a protrusion 77; the fixed shaft 72 is installed on the side wall of the supporting plate 51, one end of the fixed shaft 72 is rotatably connected to the friction wheel 71, and the friction wheel 71 is slidably connected to the rack 54; the limiting plate 74 is installed on the side wall of the brake rod 62, and the fixed rod 73 is installed on one end of the limiting plate 74; the interior of the fixed rod 73 is slidably connected to the limiting rod 76 whose side wall is an I-shaped side wall, the interior of the fixed rod 73 is installed with the second spring 75, and the second spring 75 is connected to the side wall of the limiting rod 76; the side wall of the friction wheel 71 is installed with the protrusions 77 distributed in an annular manner, and the protrusions 77 abut against the limiting rod 76.

[0058] Specifically, when the support plate 41 does not need to be fixed, the friction wheel 71 rotates on the side wall of the fixed shaft 72, and when the brake rod 62 moves toward the side wall of the T-shaped guide rail 43, the brake rod 62 drives the limit plate 74, the fixed rod 73 and the limit rod 76 to move, so that the limit rod 76 moves to resist the protrusion 77 and the friction wheel 71, and with the movement of the brake rod 62, the fixed rod 73 moves to compress the second spring 75, and the second spring 75 reversely squeezes the limit rod 76, so that the limit rod 76 is tightly pressed against the friction wheel 71, so that the friction wheel 71 engages with the rack 54 to prevent the support plate 51 from moving on the side wall of the guide rail 43.

[0059] like Figure 2 and Figure 5 As shown, the guide mechanism 8 is connected to the monorail crane walking device 5; the guide mechanism 8 includes a rubber pad 81, a partition 82, a metal plate 83 and a steel ball 84, the metal plate 83 and the partition 82 are installed on the bottom surface of the T-shaped guide rail 43, and the side wall of the metal plate 83 is slidingly connected to the steel ball 84; the side wall of the support plate 51 is symmetrically installed with the rubber pad 81, and the elastic rubber pad 81 is rollingly connected to the steel ball 84.

[0060] Specifically, when the support plate 51 moves along the side wall of the T-shaped guide rail 43, the support plate 51 drives the rubber pad 81 and the steel ball 84 to move, and the side wall of the metal plate 83 is arc-shaped, and the steel ball 84 moves along the side wall of the metal plate 83, so that the sliding between the support plate 51 and the T-shaped guide rail 43 is more stable. At the same time, the rolling between the support plate 51 and the T-shaped guide rail 43 is achieved by the steel ball 84, so that the monorail crane walking device 5 has a small deviation in the walking trajectory.

[0061] Furthermore, the partition 82 is located between the two metal plates 83 , and the side walls of the metal plates 83 are arc-shaped. The side walls of the metal plates 83 are arc-shaped, and the rubber pad 81 is fixedly connected to the support plate 51 , so that the arc-shaped metal plate 83 has a good guiding effect on the support plate 51 .

[0062] The working principle of the distributed drive assembly system of the permanent magnet monorail crane provided by the present invention is as follows:

[0063] During normal operation, when the lifting bracket 2 moves, the hydraulic cylinder 64 is energized, the hydraulic cylinder 64 operates and contracts, the connecting rod 61 is rotationally connected to the hydraulic cylinder 61, the piston rod of the hydraulic cylinder 64 is sleeved with a first spring 63, the hydraulic cylinder 64 contracts and compresses the first spring 63, the support rod 66 is fixed to the side wall of the support plate 51, and the support rod 66 is rotationally connected to the connecting rod 61, and the hydraulic cylinder 64 contracts to drive the connecting rod 61 to rotate, and the connecting rod 61 drives the brake rod 62 to move, so that the brake pad 65 is separated from the side wall of the T-shaped guide rail 42;

[0064] The operation of the permanent magnet motor 52 drives the driving gear 53 to rotate, and the driving gear 53 is meshed with the rack 54. The driving gear 53 moves along the rack 54, pushing the support plate 51 to slide along the T-shaped guide rail 43. The support plate 51 drives the driven gear 55 to move along the rack 54, increasing the stability of the support plate 51 moving on the side wall of the T-shaped guide rail 43. The rack 54 cooperates with the driving gear 53 of the monorail crane walking device to improve the climbing ability or slow down the speed when going downhill, making the monorail hanging bracket safer, and the driving gear 53 and the driven gear 55 move along the rack 54, and the rack 54 blocks the driving gear 53 and the driven gear 55 from moving downward, which facilitates the hanging bracket 2 to climb.

[0065] See also Figure 2 , Figure 3 and Figure 5 When the support plate 51 moves along the side wall of the T-shaped guide rail 43, the support plate 51 drives the rubber pad 81 and the steel ball 84 to move, and the side wall of the metal plate 83 is arc-shaped, and the steel ball 84 moves along the side wall of the metal plate 83, so that the sliding between the support plate 51 and the T-shaped guide rail 43 is more stable. At the same time, the rolling between the support plate 51 and the T-shaped guide rail 43 is achieved by the steel ball 84, so that the monorail crane walking device 5 has a small deviation in the walking trajectory, and the rubber pad 81 has a buffering effect on the vibration generated by the support plate 51 during the walking process of the T-shaped guide rail 43. Furthermore, the side wall of the metal plate 83 is arc-shaped, and the rubber pad 81 is fixedly connected to the support plate 51, so that the arc-shaped metal plate 83 has a good guiding effect on the support plate 51.

[0066] When the hydraulic cylinder 64 fails or loses power during the travel of the lifting bracket 2, the first spring 63 compressed by the hydraulic cylinder 64 stretches, causing the connecting rod 61 to rotate in the opposite direction. At the same time, the connecting rod 61 rotates to connect the brake rod 62, and the connecting rod 61 rotates to push the brake rod 62 to move in the direction of the T-shaped guide rail 43, so that the brake rod 62 pushes the brake pad 65 to close to the side wall of the T-shaped guide rail 43, and when the brake rod 62 moves toward the side wall of the T-shaped guide rail 43, the brake rod 62 drives the brake pad 65 to move in the direction of the T-shaped guide rail 43. The limiting plate 74, the fixing rod 73 and the limiting rod 76 move, so that the limiting rod 76 moves to contact the protrusion 77 and the friction wheel 71, and with the movement of the brake rod 62, the fixing rod 73 moves to compress the second spring 75, and the second spring 75 reversely squeezes the limiting rod 76, so that the limiting rod 76 is tightly pressed against the friction wheel 71, so that the friction wheel 71 engages with the rack 54, preventing the support plate 51 from moving on the side wall of the guide rail 43, and preventing the lifting bracket 2 from sliding downward and causing damage.
