Description

Technical Field

[0001] This invention relates to the field of mining elevator technology, specifically to a safety protection device for mining elevators. Background Technology

[0002] Mining elevators play a vital role in mining operations, safely transporting personnel and equipment to underground work areas. However, due to their unique working environment and complex operating conditions, they also face some common safety risks.

[0003] Due to the high lateral pressure, the shaft of a mine is prone to deformation. The guide rails of existing mining elevators are easily affected by the deformation of the shaft wall, which can cause jamming of the car during normal up and down movement, resulting in people or equipment being trapped inside the mining elevator, or even causing serious elevator safety accidents. Therefore, they cannot meet the lifting requirements of mines. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the present invention provides a safety protection device for mining elevators, which at least partially solves the problems mentioned in the background art.

[0005] The technical solution adopted in this invention is as follows: a safety protection device for a mining elevator, comprising a reinforcement layer, a fixed adjustment component, a connector, a guide rail, a car, and a movable guide component.

[0014] The support base is located at the upper end of the base;

[0015] The fixed end of the hydraulic device is mounted on the support base, and the movable end of the hydraulic device is movably inserted through the support base and located in the movable groove. The movable end of the hydraulic device is positioned above the end near the drive rod.

[0016] The connector is movably located at the other end of the drive rod.

[0017] Furthermore, the movable guide assembly includes a sliding base assembly and an elastic guide assembly. Both the upper and lower crossbeams are provided with sliding grooves, and the sidewalls of the sliding grooves are provided with wire holes. The sliding base assembly is slidably disposed on the sliding grooves, and the elastic guide assembly is fixedly disposed on the sliding base assembly.

[0018] Furthermore, the sliding base assembly includes a sliding plate, a slider, a sliding rod, a strong spring, and a guide base.

[0019] The slider is located on the lower wall of the sliding plate;

[0020] The sliding plate is movably mounted in the slide groove via a slider;

[0021] The slide bar is configured to flexibly pass through the slider and the wire hole;

[0022] One end of the strong spring is disposed against the side wall of the slide groove, and the other end of the strong spring is disposed against the slider;

[0023] The guide base is fixedly mounted on the sliding plate;

[0024] The elastic guide component is fixedly mounted on the guide base.

[0025] Furthermore, the elastic guide assembly includes a bracket, a support rod, a forward rotation shaft, a guide wheel, a side bracket, a side support rod, a side rotation shaft, and a side guide wheel.

[0026] The bracket is provided in two sets, and the two sets of brackets are symmetrically arranged on the guide base;

[0027] The lower end of the support rod is movably connected to the bracket.

[0028] The forward rotation shaft is movably connected to two sets of support rods;

[0029] The guide wheel is fixedly mounted on the forward rotation shaft;

[0030] The guide rail is T-shaped, and the guide wheel is movably connected to the front wall of the guide rail;

[0031] The side bracket is fixedly mounted on the guide base, and the side bracket is positioned close to the outer side of the guide base.

[0032] The lower end of the side support rod is movably connected to the side bracket;

[0033] The side rotating shaft is movably connected to the side support rod, and the central axis of the side rotating shaft is perpendicularly intersecting the central axis of the front rotating shaft.

[0034] The side guide wheel is fixedly mounted on the side rotating shaft, and the side guide wheel is movably connected to the side wall of the guide rail.

[0035] Furthermore, the guide base is provided with a fixing rod, which is located at the intersection of the central axis of the support and the central axis of the side support. The upper end of the support rod and the side support rod are provided with a protrusion, which is located on the side of the support and the side support. A limiting rod is movably inserted through the protrusion, and one end of the limiting rod is movably inserted through the fixing rod. Both ends of the limiting rod are provided with a limiting block.

[0036] Furthermore, an auxiliary rod is movably connected through the protrusion, one end of the auxiliary rod is movably connected through the fixed rod, and a weak spring is provided on the other end of the auxiliary rod. Limiting blocks are provided at both ends of the auxiliary rod, one end of the weak spring abuts against the limiting block, and the other end of the weak spring abuts against the protrusion.

[0037] In a further embodiment, the initial tension of the weak spring is less than the initial tension of the strong spring, which is less than the maximum tension of the weak spring.

[0038] In a further embodiment, a traction rope is provided on the top of the car.

[0039] The beneficial effects achieved by the present invention using the above structure are as follows:

[0040] When deformation of the shaft sidewall and other potential risks affect the guide rail, the fixed adjustment component can synchronously adjust the guide rail to adjust the distance between the guide rail and the mine shaft, so as to avoid safety risks caused by shaft deformation. Since the distance between the two sets of upper crossbeams and the two sets of lower crossbeams is greater than the width of the guide rail, when the fixed adjustment component moves the guide rail closer to the car, the guide rail is displaced between the two sets of upper crossbeams and lower crossbeams. At the same time, the guide rail squeezes the movable guide component closer to the car, so as to continue to achieve the effect of guiding the direction of the car's movement.

[0041] When the guide rail compresses the guide wheel significantly, the weak spring contracts first. When the compression force reaches the initial tension of the strong spring, the guide base drives the sliding plate to slide on the groove, compressing the strong spring and causing it to contract. Under the combined action of the strong and weak springs, after the guide rail moves closer to the car, the guide wheel and the side guide wheel still maintain close contact with the guide rail, thus avoiding the deformation of the shaft from affecting the normal operation of the car.

[0053] Mining elevators play a vital role in mining operations, safely transporting personnel and equipment to underground work areas. However, due to their unique working environment and complex operating conditions, they also face some common safety risks.

[0054] Due to the high lateral pressure, the shaft of a mine is prone to deformation. The guide rails of existing mining elevators are easily affected by the deformation of the shaft wall, which can cause scraping and jamming of the car during normal up and down movement, leading to the entrapment of personnel or equipment inside the mining elevator, or even serious elevator safety accidents. Therefore, they cannot meet the lifting requirements of mines.

[0055] After recognizing the above problems, this application proposes and discloses a safety protection device for mining elevators, which can prevent safety risks caused by the deformation of the shaft of the guide rail.

[0056] Refer to the attached diagram, as follows Figure 1 and Figure 2As shown, this embodiment of the present disclosure provides a safety protection device for a mining elevator, including a reinforcing layer 2, a fixed adjustment assembly 3, a connector 4, a guide rail 5, a car 6, and a movable guide assembly 10. The reinforcing layer 2 is provided in two sets, upper and lower. The upper set of reinforcing layers 2 is symmetrically arranged on both sides of the upper end of the shaft 1, and the lower set of reinforcing layers 2 is symmetrically arranged on the side wall of the shaft 1 and close to the bottom wall of the shaft 1. The upper set of reinforcing layers 2 and the lower set of reinforcing layers 2 are arranged on the same vertical axis. The fixed adjustment assembly 3 is fixedly arranged on the upper and lower sets of reinforcing layers 2 respectively. The connector 4 is movably arranged on the adjustment mechanism of the fixed adjustment assembly 3. At the output end, the upper and lower ends of the guide rail 5 are fixedly mounted on the upper and lower sets of connecting parts 4 respectively. The top of the car 6 is provided with two sets of upper crossbeams 8, and the distance between the two sets of upper crossbeams 8 is greater than the width of the guide rail 5. The bottom of the car 6 is provided with two sets of lower crossbeams 9, which are symmetrically arranged with the upper crossbeams 8. Both ends of the upper crossbeams 8 and the lower crossbeams 9 extend close to the sides of the guide rail 5. The upper crossbeams 8 and the lower crossbeams 9 are mirrored with movable guide components 10, which are movably connected to the guide rail 5. The movable guide components 10 are configured to guide the movement direction of the car 6.

[0057] In this embodiment, the fixed adjustment component 3 can synchronously adjust the guide rail 5 to adjust the distance between the guide rail 5 and the mine shaft 1, so as to avoid the safety risks caused by the deformation of the shaft 1. Since the distance between the two sets of upper crossbeams 8 (lower crossbeams 9) is greater than the width of the guide rail 5, when the fixed adjustment component 3 drives the guide rail 5 to approach the car 6, the guide rail 5 is displaced between the two sets of upper crossbeams 8 (lower crossbeams 9), and at the same time, the guide rail 5 squeezes the movable guide component 10 to approach the car 6, so as to continue to achieve the effect of guiding the movement direction of the car 6.

[0058] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the fixed adjustment assembly 3 includes a base 11, a drive rod 12, a support base 13, and a hydraulic device 14. The base 11 is mounted on the reinforcement layer 2 and is in an inverted L-shape with a movable groove 15. The drive rod 12 is movably mounted in the movable groove 15 via a rotating shaft. One end of the drive rod 12 is located in the movable groove 15, and the other end is located outside the movable groove 15 and close to the well shaft 1. The support base 13 is located on the upper end of the base 11. The fixed end of the hydraulic device 14 is mounted on the support base 13, and the movable end of the hydraulic device 14 movably passes through the support base 13 and is located in the movable groove 15. The movable end of the hydraulic device 14 is located above the end of the drive rod 12, and the connecting piece 4 is movably mounted on the other end of the drive rod 12.

[0059] In this embodiment, by synchronously controlling the moving end of the hydraulic device 14 to press the drive rod 12, the other end of the drive rod 12 is lifted. The other end of the drive rod 12 drives the upper and lower ends of the guide rail 5 to move away from the shaft 1 and closer to the car 6 through the connector 4, thereby maintaining a safe distance when the side wall of the shaft 1 deforms.

[0060] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the movable guide assembly 10 includes a sliding base assembly 16 and an elastic guide assembly 17. Both the upper crossbeam 8 and the lower crossbeam 9 are provided with a slide groove 18. The side wall of the slide groove 18 is provided with a wire hole 19. The sliding base assembly 16 is slidably disposed on the slide groove 18, and the elastic guide assembly 17 is fixedly disposed on the sliding base assembly 16.

[0061] In this embodiment, when the other end of the drive rod 12 drives the upper and lower ends of the guide rail 5 to move away from the shaft 1 and closer to the car 6 through the connector 4, the guide rail 5 squeezes the sliding base assembly 16 and slides on the slide groove 18 to get closer to the car 6, and the guide rail 5 is displaced between the two sets of upper crossbeams 8 and the two sets of lower crossbeams 9.

[0062] like Figure 3 , Figure 4 and Figure 5 As shown, the sliding base assembly 16 includes a sliding plate 20, a slider 21, a slide rod 22, a strong spring 23, and a guide base 24. The slider 21 is disposed on the lower wall of the sliding plate 20, and the sliding plate 20 is movably disposed in the slide groove 18 via the slider 21. The slide rod 22 is movably disposed through the slider 21 and the wire hole 19. One end of the strong spring 23 is disposed against the side wall of the slide groove 18, and the other end of the strong spring 23 is disposed against the slider 21. The guide base 24 is fixedly disposed on the sliding plate 20, and the elastic guide assembly 17 is fixedly disposed on the guide base 24.

[0063] When the guide rail 5 presses against the movable guide component 10, the sliding plate 20 slides in the groove 18 through the slider 21 to compress the strong spring 23 and contract. Under the elastic restoring force of the strong spring 23, the elastic guide component 17 on the guide base 24 can still maintain active contact with the guide rail 5, thereby continuing to guide the movement direction of the car 6.

[0064] like Figure 4 and Figure 5As shown, the elastic guide assembly 17 includes a bracket 25, a support rod 26, a forward rotation shaft 27, a guide wheel 28, a side bracket 29, a side support rod 30, a side rotation shaft 31, and a side guide wheel 32. Two sets of brackets 25 are symmetrically arranged on the guide base 24. The lower end of the support rod 26 is movably connected to the bracket 25. The forward rotation shaft 27 is movably connected to both sets of support rods 26. The guide wheel 28 is fixedly mounted on the forward rotation shaft 27. The guide rail 5 is T-shaped. Wheel 28 is movably connected to the front wall of guide rail 5. Side bracket 29 is fixed on guide base 24 and is located near the outside of guide base 24. The lower end of side support rod 30 is movably connected to side bracket 29. Side rotating shaft 31 is movably connected to side support rod 30. The central axis of side rotating shaft 31 is perpendicularly intersecting the central axis of front rotating shaft 27. Side guide wheel 32 is fixed on side rotating shaft 31 and is movably connected to the side wall of guide rail 5.

[0065] In this embodiment, the guide wheel 28 is movably connected to the front wall of the T-shaped guide rail 5, and the side guide wheels 32 are movably connected to the side walls of the T-shaped guide rail 5, thereby achieving positioning of the car 6 in multiple directions of the up and down lines.

[0066] like Figure 4 and Figure 5 As shown, a fixing rod 33 is provided on the guide base 24. The fixing rod 33 is located at the intersection of the central axis of the bracket 25 and the central axis of the side bracket 29. The upper ends of the support rod 26 and the side support rod 30 are provided with protrusions 34. The protrusions 34 are located on the side close to the bracket 25 and the side bracket 29. A limiting rod 35 is movably inserted through the protrusion 34. One end of the limiting rod 35 is movably inserted through the fixing rod 33. Both ends of the limiting rod 35 are provided with limiting blocks. When the guide rail 5 squeezes the guide wheel 28 and the side guide wheel 32, the guide wheel 28 and the side guide wheel 32 respectively drive the support rod 26 and the side support rod 30 to deviate. The limiting rod 35 limits the offset distance of the support rod 26 and the side support rod 30 to prevent the guide wheel from derailing due to excessive offset.

[0067] like Figure 4 and Figure 5 As shown, an auxiliary rod 36 is movably connected through the protrusion 34. One end of the auxiliary rod 36 is movably connected through the fixed rod 33, and a weak spring 37 is provided on the other end of the auxiliary rod 36. Limiting blocks are provided at both ends of the auxiliary rod 36. One end of the weak spring 37 is set against the limiting block, and the other end of the weak spring 37 is set against the protrusion 34. When the guide wheel 28 and the side guide wheel 32 move on the guide rail 5 and generate a small vibration, the guide wheel 28 and the side guide wheel 32 respectively drive the support rod 26 and the side support rod 30 to vibrate. The weak spring 37 is used to buffer the vibration amplitude of the guide wheel 28 and the side guide wheel 32, thereby increasing the smoothness and comfort of the car 6 going up and down.

[0068] In this embodiment, the initial tension of the weak spring 37 is less than the initial tension of the strong spring 23, which is less than the maximum tension of the weak spring 37. When the movable end of the control hydraulic device 14 presses the drive rod 12, thereby lifting the other end of the drive rod 12, the other end of the drive rod 12 drives the upper and lower ends of the guide rail 5 to move away from the shaft 1 and closer to the car 6 through the connector 4. At this time, the guide rail 5 squeezes the movable guide assembly 10. When the guide rail 5 squeezes the guide wheel 28 significantly, the weak spring 37 is first compressed by force. When the squeezing force reaches the initial tension of the strong spring 23, the guide base 24 drives the sliding plate 20 to slide on the slide groove 18, squeezing the strong spring 23 and causing it to compress. Under the combined action of the strong spring 23 and the weak spring 37, after the guide rail 5 moves closer to the car 6, the guide wheel 28 and the side guide wheel 32 still maintain close contact with the guide rail 5, thereby avoiding the deformation of the shaft 1 from affecting the normal operation of the car 6.

[0069] like Figure 1 , Figure 2 and Figure 3 As shown, the top of the elevator car 6 is equipped with a traction rope 38, which is used to pull the elevator car 6 up and down.
