A mine hoist designed to prevent material overloading

Abstract

This invention relates to the field of mine hoist technology and discloses a mine hoist designed to prevent material overload. The hoist includes a base, a central shaft rotatably connected to the inner wall of the top through-hole of the base, and a winch fixedly connected to the outer wall of the central shaft. To address the problem of overweight ore, a transmission mechanism and an auxiliary mechanism are installed inside the equipment. Under normal conditions, the gear rod drives the circular tube, central shaft, and winch to rotate counterclockwise via a latching assembly. When the ore is overloaded, the hydraulic press continues to drive the gear rod to rotate counterclockwise. The pressure from the rotating gear rod acts on the bottom of the sliding plate, forcing it to slide upwards. When the end of the spring telescopic rod near the sliding plate exceeds the end near the track frame, the sliding plate is quickly pushed upwards by the spring telescopic rod. This ensures that when the winch is subjected to excessive pressure, the pressure-bearing component and the latching assembly will directly disconnect, allowing the gear rod to idle and preventing the hydraulic press from bearing excessive pressure.

Description

Technical Field

[0001] This invention relates to the field of mine hoist technology, specifically to a mine hoist designed to prevent material overloading. Background Technology

[0002] A hoist is a large mechanical device that transports goods by changing potential energy. Examples include mine hoists and dam hoists. In a broader sense, elevators, overhead cranes, winches, trolleys, cranes, and gate hoists can all be called hoists. Hoists generally refer to large mechanical devices with high power and strong lifting capacity. They complete the transportation process by driving steel wire ropes and the goods being transported up and down through power machinery.

[0003] In this process, the mined ore is fed into the hopper of the mine hoist in a quantitative manner by the conveyor. However, due to the uneven distribution of mineral content inside the ore, there will be a weight difference between ore of equal volume. When the hopper is filled with ore with higher mineral content, the material may be overloaded, causing excessive damage to the motor during subsequent hoisting of the hopper. To address the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a mine hoist for preventing material overloading, including a base, a central shaft rotatably connected to the inner wall of the top through hole of the base, a winch fixedly connected to the outer wall of the central shaft, and a hydraulic press fixedly connected to the top of the base, and further including:

[0005] The transmission mechanism is fixedly installed at the output end of the hydraulic press;

[0006] The auxiliary mechanism is fixedly installed on the outer wall of the transmission mechanism;

[0007] A limiting mechanism is fixedly installed on the outer wall of the transmission mechanism.

[0008] Before use, it is necessary to ensure that the connection between the transmission mechanism and the auxiliary mechanism is stable, and then connect the cables inside the winch to the elevator.

[0009] Preferably, the transmission mechanism includes:

[0010] The pressure-bearing component is fixedly installed on the outer wall of the output end of the hydraulic press.

[0011] The snap-fit ​​assembly is fixedly installed on the outer wall of the pressure-bearing component;

[0012] Under normal conditions, the latching assembly will be locked onto the outer wall of the pressure-bearing assembly to ensure that the rotational force of the hydraulic press can be transmitted to the winch position through the pressure-bearing assembly, the latching assembly, and the auxiliary mechanism.

[0013] Preferably, the auxiliary mechanism includes:

[0014] A rotating component is fixedly mounted on the side wall of the snap-fit ​​component;

[0015] Pressure assembly, which is fixedly installed on the side wall of the pressure-bearing assembly;

[0016] When the latching component slides, it forces the rotating component to rotate, which in turn drives the pressure component to rotate synchronously.

[0017] Preferably, the limiting mechanism includes:

[0018] A rotating assembly is rotatably mounted on the outer wall of the transmission mechanism;

[0019] A reset component is fixedly mounted on the outer wall of the rotating component.

[0020] When the hydraulic press drives the pressure-bearing component to rotate in the opposite direction, the rotating component will drive the rotating component and the latching component to reset through the reset component.

[0021] Preferably, the pressure-bearing component includes a gear rod fixedly connected to the output end of the hydraulic press, and a round tube rotatably connected to the end of the gear rod away from the hydraulic press, with several through-hole slots opened on the outer wall of the round tube;

[0022] The end of the round tube furthest from the hydraulic press is fixedly connected to the end of the central shaft.

[0023] Preferably, the buckle assembly includes a track frame fixedly connected to the outer wall of several through-hole slots, a sliding plate slidably connected to the inner wall of the track frame, and a spring telescopic rod rotatably connected to the side wall of the track frame;

[0024] The end of the spring telescopic rod furthest from the track frame is rotatably connected to the side wall of the sliding plate.

[0025] Preferably, the rotating assembly includes a first rolling column rotatably connected to the side wall of the sliding plate, a toothed rod fixedly connected to the side of the sliding plate away from the first rolling column, a first gear rotatably connected to the side of the track frame away from the first rolling column, and a second gear fixedly connected to the side wall of the first gear.

[0026] In this configuration, the sidewall of gear one meshes with the sidewall of the rack.

[0027] Preferably, the pressure assembly includes a ring 1 fixedly connected to the side of the circular tube away from the central shaft, and a toothed ring rotatably connected to the inner wall of the ring 1.

[0028] The inner wall of the gear ring meshes with the outer walls of several gears. When the gear ring rotates along the inner wall of the ring, the gears will rotate in the same direction.

[0029] Preferably, the rotating assembly includes a rotating ring rotatably connected to the outer wall of the gear rod, and a plurality of support frames are fixedly connected to the outer wall of the gear rod, with a rolling column rotatably connected to the end of the support frame away from the gear rod.

[0030] When the gear rod rotates, the support frame and the rotating ring will rotate in the same direction.

[0031] Preferably, the reset assembly includes several limiting frames fixedly connected to the outer wall of the rotating ring, and inclined sliders are slidably connected to the inner wall of the limiting frames;

[0032] Among them, the top inclined surface of the inclined slider has a smaller inclination angle, while the bottom inclined surface of the inclined slider has a larger inclination angle. In addition, a spring is fixed at the top of the inclined slider to drive the inclined slider to reset. When the side wall of the second rolling column contacts the inner wall of the limit frame, the through hole groove will be aligned with the groove of the gear rod.

[0033] The present invention has the following beneficial effects:

[0034] (1) This invention addresses the problem of overweight ore by incorporating a transmission mechanism and an auxiliary mechanism within the equipment. Under normal conditions, the gear rod drives the round tube, central shaft, and winch to rotate counterclockwise via the snap-fit ​​assembly. When the ore is overloaded, the winch bears excessive pressure, while the hydraulic press continues to drive the gear rod to rotate counterclockwise. The pressure from the gear rod's rotation acts on the bottom of the sliding plate, forcing it to slide upwards. As the sliding plate moves upwards, when the end of the spring telescopic rod near the sliding plate exceeds the end near the track frame, the sliding plate will be pushed upwards rapidly by the spring telescopic rod, presenting a... Figure 11 In the state of K, through the application of the above components, it is ensured that when the winch is subjected to excessive pressure, the pressure-bearing components and the buckling components will be directly disconnected, causing the gear rod to rotate freely and preventing the hydraulic press from being subjected to excessive pressure.

[0035] (2) This invention utilizes the characteristic of the sliding plate sliding up and down along the inner wall of the track frame. An auxiliary mechanism is provided on the inner wall of the equipment. When the sliding plate moves upward along the inner wall of the track frame, such as... Figure 8 As shown, when the sliding plate moves upward, it will drive the rack to move upward synchronously, and force gear one to make a selection. The rotating gear one will drive the gear ring to rotate along the inner wall of the ring one through gear two. Multiple gear twos are meshed with the gear ring, which makes multiple sliding plates move synchronously when the gear ring rotates. Through the application of the above components, it is ensured that multiple sliding plates can retract, preventing the problem of one or more sliding plates failing to retract in time, causing continuous contact between the sliding plate and the gear rack, and causing wear at the end of the sliding plate.

[0036] (3) This invention utilizes the characteristic of the sliding plate driving the rolling column upwards. A limiting mechanism is installed inside the equipment. When the equipment needs to be reset, the operator first restricts the rotation of the central shaft using the buckle, and then the operator connects the power supply to the hydraulic press, causing the hydraulic press to drive the gear rod to rotate clockwise, such as... Figure 13 As shown, when the second rolling column moves to the left, the inclined plane slider at the top of the limited inclined plane slider will be forced to press downward. At the same time, as the outer wall of the second rolling column contacts the inner wall of the limiting frame, the gear rod will drive the limiting frame and the rotating ring to rotate in the same direction through the support frame and the second rolling column. The rotating limiting frame will drive the inclined plane slider to rotate clockwise, and the bottom inclined plane of the inclined plane slider will press the first rolling column and the sliding plate to slide downward. During the downward sliding of the sliding plate, the spring telescopic rod will undergo a compression and release process, and finally drive the end of the sliding plate to be stuck in the groove of the gear rod. Through the application of the above components, the equipment can quickly return to the initial state.

[0037] (4) During the use of this invention, when the side wall of the second rolling column contacts the inner wall of the limiting frame, the through hole groove will be aligned with the groove of the gear rod, ensuring that the end of the sliding plate can be accurately inserted into the gap of the gear rod when the sliding plate is reset and sliding. In addition, after the sliding plate slides down, the first rolling column will be completely away from the bottom of the inclined slider. Then, the second rolling column will move to the left again under the drive of the gear rod. The inclined slider will be reset under the drive of the spring. The inclined slider will slide upward along the inner wall of the limiting frame. Through the application of the above components, the inclined slider and the first rolling column are separated under normal conditions, preventing jamming when the sliding plate drives the first rolling column to move upward.

[0054] 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.

[0055] Example 1, please refer to Figure 1 - Figure 7This invention relates to a mine hoist designed to prevent material overloading, comprising a base 13, a central shaft 14 rotatably connected to the inner wall of the top through hole of the base 13, a winch 15 fixedly connected to the outer wall of the central shaft 14, and a hydraulic press 16 fixedly connected to the top of the base 13. It also includes:

[0056] Transmission mechanism 1 is fixedly installed at the output end of hydraulic press 16;

[0057] Auxiliary mechanism 2 is fixedly installed on the outer wall of transmission mechanism 1;

[0058] Restriction mechanism 3 is fixedly installed on the outer wall of transmission mechanism 1;

[0059] Before use, fix the equipment in the required position, and then connect the cable inside the central shaft 14 to the mine cable car or mine hoist. When it is necessary to lift, the hydraulic press 16 drives the central shaft 14 and the winch 15 to rotate counterclockwise through the transmission mechanism 1 and the auxiliary mechanism 2 to complete the basic lifting process.

[0060] Transmission mechanism 1 includes:

[0061] Pressure-bearing component 11 is fixedly installed on the outer wall of the output end of the hydraulic press 16;

[0062] The snap-fit ​​assembly 12 is fixedly disposed on the outer wall of the pressure-bearing assembly 11;

[0063] Under normal conditions, the latching assembly 12 will be latched onto the outer wall of the pressure-bearing assembly 11 to ensure that the rotational force of the hydraulic press 16 can be transmitted to the winch 15 position through the pressure-bearing assembly 11, the latching assembly 12 and the auxiliary mechanism 2.

[0064] Auxiliary mechanism 2 includes:

[0065] Rotating component 21 is fixedly disposed on the side wall of the snap-fit ​​component 12;

[0066] Pressure component 22 is fixedly installed on the side wall of pressure-receiving component 11;

[0067] When the latching assembly 12 slides, it forces the rotating assembly 21 to rotate, which in turn drives the pressure assembly 22 to rotate synchronously.

[0068] Restricted agency 3 includes:

[0069] Rotating assembly 31 is rotatably disposed on the outer wall of transmission mechanism 1;

[0070] Reset component 32 is fixedly disposed on the outer wall of rotating component 31;

[0071] When the hydraulic press 16 drives the pressure-bearing component 11 to rotate in the opposite direction, the rotating component 31 will drive the rotating component 21 and the latching component 12 to reset through the reset component 32.

[0072] Example 2, please refer to Figure 4 - Figure 13 The present invention is a mine hoist that prevents material overload. Based on Example 1, the pressure-bearing component 11 includes a gear rod 111 fixedly connected to the output end of the hydraulic press 16. A circular tube 112 is rotatably connected to the end of the gear rod 111 away from the hydraulic press 16. Several through-hole grooves 113 are opened on the outer wall of the circular tube 112.

[0073] The end of the round tube 112 away from the hydraulic press 16 is fixedly connected to the end of the central shaft 14.

[0074] The buckle assembly 12 includes a track frame 121 fixedly connected to the outer wall of a plurality of through-hole slots 113, a sliding plate 122 slidably connected to the inner wall of the track frame 121, and a spring telescopic rod 123 rotatably connected to the side wall of the track frame 121.

[0075] To address the issue of excessive ore weight, a transmission mechanism 1 and an auxiliary mechanism 2 are installed inside the equipment. Under normal conditions, the spring telescopic rod 123 is in a downward rotating state, pushing the sliding plate 122 downwards along the inner wall of the track frame 121. The end of the sliding plate 122 is engaged inside the slot of the gear rod 111, presenting an appearance as follows: Figure 5 In normal conditions, the gear rod 111 drives the round tube 112, the central shaft 14, and the winch 15 to rotate counterclockwise via the snap-fit ​​assembly 12. However, when the ore is overloaded, the winch 15 bears excessive pressure, causing the winch 15 and the central shaft 14 to be unable to rotate. At this time, the hydraulic press 16 still drives the gear rod 111 to rotate counterclockwise. The rotational pressure of the gear rod 111 acts on the bottom of the sliding plate 122, forcing the sliding plate 122 to have an upward sliding tendency. If it is in an overloaded state, the resistance to the rotation of the central shaft 14 will be greater than the contraction pressure of several spring telescopic rods 123. During the upward movement of the sliding plate 122, when the end of the spring telescopic rod 123 near the sliding plate 122 exceeds the end of the spring telescopic rod 123 near the track frame 121, the sliding plate 122 will be pushed upward quickly by the spring telescopic rod 123, presenting as... Figure 11 The state of K in the middle.

[0076] The rotating assembly 21 includes a rolling column 211 rotatably connected to the side wall of the sliding plate 122, a rack 214 fixedly connected to the side of the sliding plate 122 away from the rolling column 211, a gear 212 rotatably connected to the side of the track frame 121 away from the rolling column 211, and a gear 213 fixedly connected to the side wall of the gear 212.

[0077] When the sliding plate 122 moves upward, the spring telescopic rod 123 will gradually compress. When the height of the end of the sliding plate 122 is higher than the inner wall of the through hole groove 113, the spring telescopic rod 123 has been completely compressed and is slightly tilted upward. When the inclined slider 322 squeezes the rolling column 211 downward, the rolling column 211 will drive the end of the sliding plate 122 to exceed the inner wall of the through hole groove 113, so that the spring telescopic rod 123 reaches the maximum compression state, and at the same time, the spring telescopic rod 123 is slightly tilted downward.

[0078] The pressure assembly 22 includes a ring 221 fixedly connected to the side of the circular tube 112 away from the central shaft 14, and a toothed ring 222 rotatably connected to the inner wall of the ring 221.

[0079] Taking advantage of the characteristic that the sliding plate 122 slides up and down along the inner wall of the track frame 121, an auxiliary mechanism 2 is provided on the inner wall of the equipment. When the sliding plate 122 moves upward along the inner wall of the track frame 121, such as Figure 8 As shown, when the sliding plate 122 moves upward, it will drive the rack 214 to move upward synchronously, and force the gear 1 212 to make a selection. The rotating gear 1 212 will drive the gear ring 222 to rotate along the inner wall of the ring 1 221 through the gear 213. The multiple gears 213 are meshed with the gear ring 222, which makes the multiple sliding plates 122 move synchronously when the gear ring 222 rotates. Through the application of the above components, it is ensured that the multiple sliding plates 122 can retract, preventing the problem that one or more sliding plates 122 cannot retract in time, causing the sliding plate 122 to be in continuous contact with the gear rack 111 and causing wear at the end of the sliding plate 122.

[0080] The rotating assembly 31 includes a rotating ring 311 rotatably connected to the outer wall of the gear rod 111, and a plurality of support frames 312 are fixedly connected to the outer wall of the gear rod 111. A rolling column 313 is rotatably connected to one end of the support frame 312 away from the gear rod 111.

[0081] During use, when the side wall of the second rolling column 313 contacts the inner wall of the limiting frame 321, the through hole groove 113 will be aligned with the groove of the gear rod 111, ensuring that the end of the sliding plate 122 can be accurately inserted into the gap of the gear rod 111 when the sliding plate 122 is reset and sliding. In addition, after the sliding plate 122 slides down, the first rolling column 211 will be completely away from the bottom of the inclined slider 322. Then, the second rolling column 313 will move to the left again under the drive of the gear rod 111. The inclined slider 322 will be reset under the drive of the spring and slide upward along the inner wall of the limiting frame 321. Through the application of the above components, the inclined slider 322 and the first rolling column 211 are separated under normal conditions, preventing jamming when the sliding plate 122 drives the first rolling column 211 to move upward.

[0082] The reset assembly 32 includes several limiting frames 321 fixedly connected to the outer wall of the rotating ring 311, and inclined sliders 322 are slidably connected to the inner wall of the limiting frames 321.

[0083] Utilizing the characteristic that the sliding plate 122 drives the rolling column 211 to move upward, a limiting mechanism 3 is set inside the equipment. When the end of the sliding plate 122 is inserted into the gap of the gear rod 111, the rolling column 211 is at its lowest position. During this process, the rotating rolling column 211 cannot touch the bottom slope of the inclined slider 322. When the rolling column 211 moves upward, it reaches the highest position of the bottom slope of the inclined slider 322. When the equipment needs to be reset, the operator first restricts the rotation of the central shaft 14 using the fasteners, and then connects the power supply to the hydraulic press 16, causing the hydraulic press 16 to drive the gear rod 111 to rotate clockwise. Figure 13 As shown, when the second rolling column 313 moves to the left, the inclined surface of the limited inclined slider 322 will be forced to press downward. At the same time, as the outer wall of the second rolling column 313 contacts the inner wall of the limiting frame 321, the gear rod 111 will drive the limiting frame 321 and the rotating ring 311 to rotate in the same direction through the support frame 312 and the second rolling column 313. The rotating limiting frame 321 will drive the inclined slider 322 to rotate clockwise, and the bottom inclined surface of the inclined slider 322 will press the first rolling column 211 and the sliding plate 122 to slide downward. During the downward sliding of the sliding plate 122, the spring telescopic rod 123 will undergo compression and release, and finally drive the end of the sliding plate 122 to be stuck in the groove of the gear rod 111. Through the application of the above components, the equipment can quickly return to the initial state.

[0084] One specific application of this embodiment is as follows: Before use, the equipment is fixed in the required position, and then the cable inside the central shaft 14 is connected to the mine cable car or mine hoist. When it is necessary to lift, the hydraulic press 16 drives the central shaft 14 and the winch 15 to rotate counterclockwise through the transmission mechanism 1 and the auxiliary mechanism 2 to complete the basic lifting process.

[0085] To address the issue of excessive ore weight, a transmission mechanism 1 and an auxiliary mechanism 2 are installed inside the equipment. Under normal conditions, the spring telescopic rod 123 is in a downward rotating state, pushing the sliding plate 122 downwards along the inner wall of the track frame 121. The end of the sliding plate 122 is engaged inside the slot of the gear rod 111, presenting an appearance as follows: Figure 5 In normal conditions, the gear rod 111 drives the round tube 112, the central shaft 14, and the winch 15 to rotate counterclockwise via the snap-fit ​​assembly 12. However, when the ore is overloaded, the winch 15 bears excessive pressure, causing the winch 15 and the central shaft 14 to be unable to rotate. At this time, the hydraulic press 16 still drives the gear rod 111 to rotate counterclockwise. The rotational pressure of the gear rod 111 acts on the bottom of the sliding plate 122, forcing the sliding plate 122 to have an upward sliding tendency. If it is in an overloaded state, the resistance to the rotation of the central shaft 14 will be greater than the contraction pressure of several spring telescopic rods 123. During the upward movement of the sliding plate 122, when the end of the spring telescopic rod 123 near the sliding plate 122 exceeds the end of the spring telescopic rod 123 near the track frame 121, the sliding plate 122 will be pushed upward quickly by the spring telescopic rod 123, presenting as... Figure 11 In the state of K, through the application of the above components, it is ensured that when the winch 15 is subjected to excessive pressure, the pressure-bearing component 11 and the buckling component 12 will be directly disconnected, causing the gear rod 111 to rotate freely, thus preventing the hydraulic press 16 from being subjected to excessive pressure.

[0086] Taking advantage of the characteristic that the sliding plate 122 slides up and down along the inner wall of the track frame 121, an auxiliary mechanism 2 is provided on the inner wall of the equipment. When the sliding plate 122 moves upward along the inner wall of the track frame 121, such as Figure 8 As shown, when the sliding plate 122 moves upward, it will drive the rack 214 to move upward synchronously, and force the gear 1 212 to make a selection. The rotating gear 1 212 will drive the gear ring 222 to rotate along the inner wall of the ring 1 221 through the gear 213. The multiple gears 213 are meshed with the gear ring 222, which makes the multiple sliding plates 122 move synchronously when the gear ring 222 rotates. Through the application of the above components, it is ensured that the multiple sliding plates 122 can retract, preventing the problem that one or more sliding plates 122 cannot retract in time, causing the sliding plate 122 to be in continuous contact with the gear rack 111 and causing wear at the end of the sliding plate 122.

[0087] Utilizing the characteristic that the sliding plate 122 drives the rolling column 211 to move upward, a limiting mechanism 3 is set inside the equipment. When the end of the sliding plate 122 is inserted into the gap of the gear rod 111, the rolling column 211 is at its lowest position. During this process, the rotating rolling column 211 cannot touch the bottom slope of the inclined slider 322. When the rolling column 211 moves upward, it reaches the highest position of the bottom slope of the inclined slider 322. When the equipment needs to be reset, the operator first restricts the rotation of the central shaft 14 using the fasteners, and then connects the power supply to the hydraulic press 16, causing the hydraulic press 16 to drive the gear rod 111 to rotate clockwise. Figure 13 As shown, when the second rolling column 313 moves to the left, the inclined surface of the limited inclined slider 322 will be forced to press downward. At the same time, as the outer wall of the second rolling column 313 contacts the inner wall of the limiting frame 321, the gear rod 111 will drive the limiting frame 321 and the rotating ring 311 to rotate in the same direction through the support frame 312 and the second rolling column 313. The rotating limiting frame 321 will drive the inclined slider 322 to rotate clockwise, and the bottom inclined surface of the inclined slider 322 will press the first rolling column 211 and the sliding plate 122 to slide downward. During the downward sliding of the sliding plate 122, the spring telescopic rod 123 will undergo compression and release, and finally drive the end of the sliding plate 122 to be stuck in the groove of the gear rod 111. Through the application of the above components, the equipment can quickly return to the initial state.

[0088] When the sliding plate 122 moves upward, the spring telescopic rod 123 will gradually compress. When the height of the end of the sliding plate 122 is higher than the inner wall of the through hole groove 113, the spring telescopic rod 123 has been completely compressed and is slightly tilted upward. When the inclined slider 322 squeezes the rolling column 211 downward, the rolling column 211 will drive the end of the sliding plate 122 to exceed the inner wall of the through hole groove 113, so that the spring telescopic rod 123 reaches the maximum compression state, and at the same time, the spring telescopic rod 123 is slightly tilted downward.

[0089] During the use of this invention, when the side wall of the second rolling column 313 contacts the inner wall of the limiting frame 321, the through hole groove 113 will be aligned with the groove of the gear rod 111, ensuring that the end of the sliding plate 122 can be accurately inserted into the gap of the gear rod 111 when the sliding plate 122 is reset and sliding. In addition, after the sliding plate 122 slides down, the first rolling column 211 will be completely away from the bottom of the inclined slider 322. Then, the second rolling column 313 will move to the left again under the drive of the gear rod 111. The inclined slider 322 will be reset under the drive of the spring and slide upward along the inner wall of the limiting frame 321. Through the application of the above components, the inclined slider 322 and the first rolling column 211 are separated under normal conditions, preventing jamming when the sliding plate 122 drives the first rolling column 211 to move upward.

[0090] The preferred embodiments of the present invention disclosed above are merely illustrative of the invention.
