Description

Technical Field

[0001] The present invention relates to the technical field of mining transportation equipment, and in particular to a mining elevator. Background Art

[0002] Mine elevator is also called mine hoist. It is a special form of elevator and can also be regarded as a simple lift. In the project of transporting people and objects in mines, mine hoists are very important transportation tools. Mine, especially underground conditions and working environment are worse than those on the ground. Therefore, the safety of mine hoists must be guaranteed, and its structure, working characteristics and design methods must be carefully understood and mastered. The main structural forms produced in my country are: single-rope winding single-drum and double-drum mine hoists; friction-type multi-rope floor-standing and tower-type multi-rope friction hoists.

[0003] The existing mine elevators have the following problems in actual use: On the one hand, mine elevators are different from common civil elevators. In order to improve the efficiency of transportation during underground operations, the entrances and exits of mine elevators are usually open structures, and the entrances and exits are protected by simple hand-pull protection rod structures. There is no electric-controlled elevator door with high safety performance like civil elevators. This will cause the workers and goods inside the elevator and close to the elevator door to fall from the elevator port during the elevator lifting process; and when the elevator is lifted to the designated position, there will be a certain plane error between it and the mine platform, which will affect the up and down transportation of workers and goods, and there are also safety hazards; On the other hand, when a mine elevator suddenly falls due to an accident, the safety performance of the braking device of the traditional mine elevator needs to be improved. Summary of the invention

[0004] The invention discloses a mine elevator, aiming to solve the technical problem that the safety performance of the existing mine elevator needs to be further improved during actual use.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A mine elevator comprises a guide rail and a car mounted on the outer side of the guide rail, wherein the ends of the car are symmetrically provided with protection mechanisms for protecting workers from falling, wherein the protection mechanisms comprise frame members symmetrically installed at both ends of the guide rail, wherein sliding grooves are symmetrically provided on the inner side of the frame members, and a plurality of protection rods are slidably installed inside the sliding grooves; The bottom of the protection mechanism is provided with a bridge mechanism erected between the car and the mine platform, the bridge mechanism includes a bridge rotatably mounted on the bottom of the frame, a first gear member is fixedly mounted on the end of the bridge, a second gear member is rotatably mounted on the side of the frame, and the first gear member and the second gear member are meshed and connected; An emergency stop mechanism for emergency locking is provided between the guide rail and the car, and the emergency stop mechanism comprises a plurality of suspension beams symmetrically fixed to the top and bottom of the car, and bases are fixedly installed at both ends of the suspension beams, and two rotating rollers are symmetrically distributed inside each of the bases, and the rotating rollers are rotatably installed inside the bases, and each of the bases is slidably sleeved on the outer side of the guide rail through the two rotating rollers; When the protective mechanism is folded, it will drive the bridging mechanism to be placed between the car and the mine platform, so as to facilitate workers and goods to enter the interior of the car. When the protective mechanism is extended, it will drive the bridging mechanism to fold and block, so as to protect the workers inside the car. When the car falls rapidly due to an accident, the emergency stop mechanism can lock the car.

[0006] By arranging a protective mechanism for protecting workers from falling at the end of a traditional mining elevator, when the protective mechanism is folded, it will drive the bridging mechanism below to be placed between the car and the mine platform, so as to facilitate the workers and goods to enter and exit the interior of the car. When the protective mechanism is extended, it will drive the bridging mechanism to fold and block, so as to protect the workers and goods inside the car, thereby preventing the goods and workers from falling during the elevator lifting process. When the car falls rapidly due to an accident, the emergency stop mechanism additionally arranged between the car and the guide rail can be used to lock the entire car, so as to further protect the workers inside the car, thereby greatly improving the safety of traditional mining elevators.

[0007] In a preferred solution, the protective mechanism also includes a motor fixedly mounted on the top of the frame, a winding disk is sleeved and mounted on the outer side of the output end of the motor, a traction rope is coiled and mounted on the outer side of the winding disk, and the end of the traction rope is sequentially passed through the ends of several of the protective rods and fixedly connected to the top of one of the protective rods at the bottom.

[0008] By setting up several protection rod structures controlled by motor winding, the motor winding is used in conjunction with the traction rope structure to synchronously retract and extend the several protection rods. When the workers enter the interior of the car, the several protection rods cooperate with each other to shield the two ends of the car, thereby ensuring the safety of the workers when taking the elevator.

[0009] In a preferred solution, the bridging mechanism also includes a transmission belt connected to a transmission sleeve between the second gear member and the output end of the motor, plug-ins are symmetrically installed on both sides of the top of the bridge, and slots are opened on the sides of several protective rods located below, and the flipped end of the plug-in is engaged with the inside of the slot, and the inner diameter of the slot is larger than the outer diameter of the end of the plug-in.

[0010] A bridge structure driven synchronously by a motor is arranged to be rotatably installed at the bottom of the frame. As the motor is wound up, while the protective rod is lifted, the bridge structure is synchronously driven by the transmission belt, the first gear member and the second gear member, so that the bridge structure is folded and placed between the car and the mine platform, so as to facilitate the up and down movement of workers and goods. In addition, an insert is additionally arranged on the top of the bridge and a slot is additionally arranged on the side of the protective rod. As the motor rotates in the opposite direction, the protective rod is extended and the bridge is folded to protect the goods and workers inside the car. At the same time, the cooperation between the insert and the slot can further improve the structural strength of the protective rod, thereby further improving the safety when riding in the car.

[0011] In a preferred embodiment, the emergency stop mechanism further comprises two alloy components symmetrically distributed on the outer side of each of the bases, the alloy components are rotatably mounted on the outer side of the base, the side walls of the base are symmetrically provided with central grooves, an inertia component is arranged inside the rotating roller, the extended inertia component is squeezed onto the end of the alloy component through the central groove, and a plurality of the guide rails are provided with a slot on the outer side, and the end of the rotating alloy component is engaged with the inside of the slot.

[0012] By providing a base that is slidably clamped between the guide rail and the car, the car is moved vertically to drive the rotating roller inside the base to slide synchronously along the outer side of the guide rail. When the car loses control and falls rapidly, the rotation speed of the rotating roller is accelerated, and the additional inertia component is thrown out through inertia, thereby pressing and contacting the end of the alloy component, causing the alloy component to rotate and press and engage with the outer side of the guide rail, thereby braking the falling car and protecting the workers and goods inside the car, greatly improving the safety of traditional mining elevators in emergencies.

[0013] In a preferred embodiment, the inertia component includes a plurality of receiving grooves evenly opened inside the rotating roller, an inertia block is slidably installed inside each of the receiving grooves, an elastic member is fixedly connected between the inertia block and the receiving groove, and the sliding inertia block is pressed and contacted with the end of the alloy component.

[0014] An inertia component is provided at the end of the rotating roller, and the inertia component includes an inertia block, an elastic member and a receiving groove. Under normal circumstances, the inertia block is hidden inside the receiving groove. When the car falls out of control, the rotation speed of the rotating roller is accelerated and the inertia block is thrown out and squeezed into the alloy component, thereby ensuring the integrity of the operation of the equipment.

[0015] It can be seen from the above that the mine elevator provided by the present invention has the following technical effects.

[0016] First, by arranging a plurality of protective rod structures controlled by the motor winding at the end of the car, the motor winding is used in combination with the traction rope structure to synchronously retract and extend the plurality of protective rods, thereby forming a shield for the end of the car to ensure the safety of people and objects riding in the car, and along with the winding of the motor, while driving the protective rod to be lifted, the bridge structure is synchronously driven through the transmission belt, the first gear member and the second gear member, so that the bridge structure is folded and placed between the car and the mine platform, thereby ensuring the safety of workers and goods when going up and down, and an additional plug-in is provided on the top of the bridge and an additional slot is provided on the side of the protective rod. Along with the reverse rotation of the motor, the protective rod is extended and the bridge is folded to protect the goods and workers inside the car, while the gap between the plurality of protective rods below is shielded, thereby preventing small goods from falling, and the mutual cooperation of the plug-in and the slot can further improve the structural strength of the protective rod, thereby further improving the safety when riding in the car.

[0017] Second, by providing a base that is slidably clamped between the guide rail and the car, the car is moved vertically to drive the rotating roller inside the base to slide synchronously along the outside of the guide rail. When the car loses control and falls rapidly, the rotation speed of the rotating roller accelerates, and the additional inertia block is thrown out through inertia, thereby squeezing and contacting the end of the alloy component, causing the alloy component to rotate and squeeze the outside of the guide rail, thereby applying emergency braking to the falling car and protecting the workers and goods inside the car, greatly improving the safety of traditional mining elevators in emergencies.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] The mine elevator disclosed by the present invention is mainly used for transportation inside a mine.

[0035] Reference Figures 1 to 14 A mining elevator comprises a guide rail 1, a car 2 mounted on the outside of the guide rail 1, and protective mechanisms 3 for protecting workers from falling are symmetrically arranged at the ends of the car 2. The protective mechanism 3 comprises a frame 301 symmetrically installed at both ends of the guide rail 1, and a sliding groove 302 is symmetrically opened on the inner side of the frame 301. A plurality of protective rods 303 are slidably installed inside the sliding groove 302; A bridge mechanism 4 is provided at the bottom of the protection mechanism 3 and is erected between the car 2 and the mine platform. The bridge mechanism 4 includes a bridge 401 rotatably mounted at the bottom of the frame 301. A first gear member 402 is fixedly mounted at the end of the bridge 401. A second gear member 403 is rotatably mounted on the side of the frame 301. The first gear member 402 and the second gear member 403 are meshed and connected. An emergency stop mechanism 5 for emergency locking is provided between the guide rail 1 and the car 2. The emergency stop mechanism 5 includes a plurality of suspension beams 501 symmetrically fixed to the top and bottom of the car 2. A base 502 is fixedly installed at both ends of the suspension beams 501. Two rotating rollers 503 are symmetrically distributed inside each base 502. The rotating rollers 503 are rotatably installed inside the base 502. Each base 502 is slidably sleeved on the outer side of the guide rail 1 through the two rotating rollers 503. When the protection mechanism 3 is folded, it will drive the bridging mechanism 4 to be placed between the car 2 and the mine platform, so as to facilitate the workers and goods to enter the interior of the car 2. When the protection mechanism 3 is extended, it will drive the bridging mechanism 4 to fold and block, so as to protect the workers inside the car 2. When the car 2 falls rapidly due to an accident, the emergency stop mechanism 5 can lock the car 2.

[0036] In this embodiment: the car 2 is set between several guide rails 1, and workers and goods enter the interior of the car 2 through the mine platform, and the protection mechanism 3 is started at the same time. The protection mechanism 3 will slowly extend to block the two ends of the car 2. While the protection mechanism 3 is running, the bridge mechanism 4 placed on the mine platform will be started synchronously, so as to fit the side of the protection mechanism 3 in a flipping manner and fix the protection mechanism 3. At this time, the car 2 is driven by the external lifting machine to move vertically. After the car 2 reaches the designated point, the protection mechanism 3 is started again and the end of the car 2 is exposed in a retracted manner. During the retraction of the protection mechanism 3, the bridge mechanism 4 will rotate synchronously, so as to be placed between the car 2 and the mine platform, which is convenient for workers to step on and enter and exit from the inside of the car 2; and during the vertical movement of the car 2, when the car 2 has an accident and falls rapidly, the emergency stop mechanism 5 will start and lock the car 2 to protect the people and goods inside the car 2.

[0037] Reference Figures 1 to 7 In a preferred embodiment, the protection mechanism 3 also includes a motor 304 fixedly installed on the top of the frame 301, a winding disk 305 is sleeved and installed on the outer side of the output end of the motor 304, and a traction rope 306 is coiled and installed on the outer side of the winding disk 305. The ends of the traction rope 306 pass through the ends of several protection rods 303 in sequence and are fixedly connected to the top of a protection rod 303 at the bottom.

[0038] The car 2 is set up between several guide rails 1. Workers and goods enter the interior of the car 2 through the mine platform and start the motor 304 at the same time. The motor 304 will slowly rotate the output end, thereby driving the traction rope 306 wound on the outside of the winding drum 305. The slowly released traction rope 306 will stretch several stacked protection rods 303 along the inside of the sliding groove 302 in sequence, so that the several protection rods 303 cooperate with the frame 301 to form a shield for the two ends of the car 2; when the car 2 reaches the designated point, the motor 304 is started again and drives the winding drum in the reverse rotation. 305 rotates in the opposite direction, driving the traction rope 306 and the protection rod 303 to fold in a contracting manner, thereby exposing the end of the car 2; wherein, a spring 307 is fixedly connected between the ends of two adjacent protection rods 303, and the spring 307 is sleeved on the outside of the traction rope 306. During the winding process of the traction rope 306, several springs 307 will be compressed, thereby shortening the distance between the two protection rods 303; similarly, during the lowering process of the traction rope 306, several springs 307 will lose the extrusion restriction and will be stretched synchronously, thereby increasing the distance between the two protection rods 303.

[0039] Furthermore, it is supplemented that: the top of the bridge 401 is provided with anti-slip grooves 407 to increase the friction when the workers walk on the top of the bridge 401 and prevent the workers from slipping.

[0040] Reference Figures 1 to 7 In a preferred embodiment, the bridging mechanism 4 also includes a transmission belt 404 connected between the second gear member 403 and the output end of the motor 304, plug-ins 405 are symmetrically installed on both sides of the top of the bridge 401, and slots 406 are opened on the sides of several protective rods 303 located below, and the end of the flipped plug-in 405 is engaged with the inside of the slot 406, and the inner diameter of the slot 406 is larger than the outer diameter of the end of the plug-in 405.

[0041] When the protection rod 303 is stretched out in sequence along the inside of the sliding groove 302, the rotating motor 304 drives the second gear member 403 to rotate through the transmission belt 404, and the rotating second gear member 403 drives the meshed first gear member 402 to rotate synchronously. When the first gear member 402 rotates, it drives the frame member 301 to rotate, so that the bridge 401 is placed between the car 2 and the mine platform. The specific state is as follows: Figure 4As shown; when the protection rod 303 is folded and reset in sequence along the inside of the sliding groove 302, the reversely rotating motor 304 will drive the second gear member 403 to rotate through the transmission belt 404, and the rotating second gear member 403 will drive the meshing first gear member 402 to rotate synchronously. When the first gear member 402 rotates, it will drive the bridge 401 to rotate around the frame member 301, so that the bridge 401 is reset and rotated and fits the side of the frame member 301. At the same time, the plug-in 405 located on the top of the bridge 401 will be synchronously turned over and snapped into the inside of the slot 406, thereby restricting the protection rod 303 and ensuring the structural stability of the protection rod 303. The specific state is shown in FIG. Figure 3 As shown; wherein, the inner diameter of the slot 406 is larger than the outer diameter of the end of the plug-in 405, ensuring that the bridge 401 is folded downward and the protective rod 303 is reset and folded upward without being affected by the slot 406 and the plug-in 405.

[0042] Further, it is supplemented that the flip angle of the bridge 401 is between 0 degrees and 100 degrees.

[0043] Reference Figure 1 to Figure 2 , Figures 8 to 12 In a preferred embodiment, the emergency stop mechanism 5 also includes two alloy components 504 symmetrically distributed on the outside of each base 502, the alloy components 504 are rotatably installed on the outside of the base 502, the side wall of the base 502 is symmetrically provided with a central groove 505, an inertia component 506 is arranged inside the rotating roller 503, the extended inertia component 506 is squeezed on the end of the alloy component 504 through the central groove 505, and a card slot 510 is opened on the outside of several guide rails 1, and the end of the rotating alloy component 504 is engaged with the inside of the card slot 510.

[0044] Under normal conditions, as the base 502 moves vertically along the outer side of the guide rail 1, the rotating roller 503 in contact with the guide rail 1 will rotate synchronously. When the car 2 encounters an accident and falls rapidly, the rotating roller 503 in contact with the guide rail 1 will be affected by the friction force and rotate at high speed. While rotating, the inertia component 506 will be thrown out by inertia, causing the inertia component 506 to be squeezed on the end of the alloy component 504 through the central groove 505, causing the alloy component 504 to rotate around the axis and clamped on both sides of the guide rail 1, so that the end of the alloy component 504 is engaged with the inside of the slot 510, thereby locking the falling car 2. The specific state is as follows: Fig.11As shown, the people and goods inside the car 2 are protected by emergency braking; wherein, an arc groove 508 is opened on the inner side of the central groove 505, and the inertial block 5062 after movement is distributed in the arc groove 508, and will not be squeezed and contacted with the base 502, while being able to push the alloy component 504; and a brake pad 509 is fixedly installed at the end of the alloy component 504, and the brake pad 509 is directly engaged in the inside of the card groove 510 to brake the entire car 2.

[0045] Furthermore, it is supplemented that the alloy component 504 and the base 502 are rotationally connected via an additional damping member (such as a damping shaft) to ensure the structural stability of the alloy component 504 under normal conditions. In this embodiment, a total of 16 groups of alloy components 504 are provided.

[0046] Reference Fig.12 In a preferred embodiment, the inertial assembly 506 includes a plurality of receiving grooves 5061 evenly arranged inside the rotating roller 503, and an inertial block 5062 is slidably installed inside each receiving groove 5061. An elastic member 5063 is fixedly connected between the inertial block 5062 and the receiving groove 5061, and the sliding inertial block 5062 is pressed and contacted with the end of the alloy component 504.

[0047] When the rotating roller 503 rotates at high speed, the inertial block 5062 located inside the receiving groove 5061 will be thrown out due to inertia, and squeezed to the end of the alloy component 504 through the middle groove 505. When the rotating roller 503 stops rotating, the inertial block 5062 that loses the inertial pulling restriction will be pulled by the elastic member 5063, thereby resetting and shrinking the inside of the recovery groove 5061.

[0048] Working principle: When in use, workers and goods enter the interior of the car 2 through the mine platform, and start the motor 304 at the same time. The motor 304 will slowly rotate the output end, thereby driving the traction rope 306 wound on the outside of the winding disk 305. The slowly released traction rope 306 will stretch out several stacked protection rods 303 along the inside of the sliding groove 302 in sequence, so that several protection rods 303 cooperate with the frame 301 to form a shield on both ends of the car 2. At the same time, the rotating motor 304 will pass through the transmission belt 404 drives the second gear member 403 to rotate, and the rotating second gear member 403 drives the meshed first gear member 402 to rotate synchronously. When the first gear member 402 rotates, it drives the frame member 301 to rotate, so that the bridge 401 is reset and rotated and fits against the side of the frame member 301, and the plug-in 405 located on the top of the bridge 401 is synchronously turned over and snapped into the inside of the slot 406, so as to restrict the protection rod 303 and ensure the structural stability of the protection rod 303. The specific state is as follows: Figure 3As shown; when the car 2 reaches the designated point, the motor 304 is started again and drives the winding drum 305 to rotate in the opposite direction in a reverse rotation manner, and drives the traction rope 306 and the protection rod 303 to fold in a contraction manner, thereby exposing the end of the car 2, and the reverse rotating motor 304 will drive the second gear member 403 to rotate through the transmission belt 404, and the rotating second gear member 403 will drive the meshing first gear member 402 to rotate synchronously, and the rotation of the first gear member 402 will drive the bridge 401 to rotate around the frame member 301, so that the bridge 401 is placed between the car 2 and the mine platform. The specific state is as shown in FIG. Figure 4 and Fig.13 As shown, it is convenient for workers to step on and enter and exit the interior of the car 2; and under normal circumstances, as the base 502 moves vertically along the outer side of the guide rail 1, the rotating roller 503 in contact with the guide rail 1 will rotate synchronously. If the elevator's own braking device fails or the braking effect decreases, causing the car 2 to descend rapidly, the rotating roller 503 in contact with the guide rail 1 will be affected by the friction force and rotate at high speed. While rotating, the inertia block 5062 will be thrown out from the inside of the storage groove 5061 by inertia, causing the inertia block 5062 to be squeezed on the end of the alloy component 504, causing the alloy component 504 to rotate and clamped in the slots 510 on both sides of the guide rail 1, thereby braking the entire car 2 and waiting for the arrival of maintenance personnel.
