Under the joint action of the strong spring and the weak spring, the guide wheel and the side guide wheel still maintain close contact with the guide rail after the guide rail moves close to the car, thereby avoiding the deformation of the shaft affecting the normal operation of the car.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention 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; based on the embodiments, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection.

Therefore, they cannot be understood as limitations on the embodiments.

[0023] Mine elevators play a vital role in mine operations, transporting personnel and equipment safely to underground working areas. However, due to their unique working environment and complex operating conditions, mine elevators also face some common safety accident risks.

[0024] The shaft of a mine is prone to deformation due to high lateral pressure. The guide rails of existing mining elevators are easily affected by the deformation of the shaft wall, causing scratches and jams on the normal up and down movement of the car, resulting in people or equipment being trapped in the mine elevator, and even causing serious elevator safety accidents. Therefore, they cannot meet the requirements of mine hoisting.

[0025] After recognizing the above problems, the present application proposes and discloses a safety protection device for a mine elevator, which can prevent the guide rail from being affected by shaft deformation and causing safety risks.

[0026] Referring to the accompanying drawings, Figure 1 and Figure 2 As shown, the embodiment of the present disclosure provides a safety protection device for a mine elevator, including a reinforcement layer 2, a fixed adjustment component 3, a connector 4, a guide rail 5, a car 6 and a movable guide component 10. The reinforcement layer 2 is provided with an upper and a lower groups. The upper group of reinforcement layers 2 is symmetrically arranged on both sides of the upper end of the shaft 1, and the lower layer of reinforcement layers 2 is symmetrically arranged on the side walls of the shaft 1 and close to the bottom wall of the shaft 1. The upper group of reinforcement layers 2 and the lower group of reinforcement layers 2 are arranged on the same vertical axis. The fixed adjustment components 3 are fixedly arranged on the upper and lower groups of reinforcement layers 2 respectively. The connector 4 is movably arranged on the adjustment of the fixed adjustment component 3. At the output end of the section, the upper and lower ends of the guide rail 5 are respectively fixed on the upper and lower sets of connecting parts 4, two sets of upper beams 8 are provided on the top of the car 6, and the distance between the two sets of upper beams 8 is greater than the width of the guide rail 5, and two sets of lower beams 9 are provided at the bottom of the car 6. The lower beams 9 and the upper beams 8 are symmetrically arranged, and both ends of the upper beams 8 and the lower beams 9 extend close to the two sides of the guide rail 5. The upper and lower beams 8 and 9 are mirrored at both ends with movable guide components 10, which are movably connected to the guide rail 5. The movable guide component 10 is configured to guide the movement direction of the car 6.

[0027] 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, thereby preventing the guide rail 5 from being affected by the deformation of the shaft 1 and causing safety risks. Since the distance between the two sets of upper beams 8 (lower beams 9) is greater than the width of the guide rail 5, when the fixed adjustment component 3 drives the guide rail 5 close to the car 6, the guide rail 5 moves between the two sets of upper beams 8 (lower beams 9), and at the same time, the guide rail 5 squeezes the movable guide component 10 close to the car 6, continuing to achieve the effect of guiding the movement direction of the car 6.

[0028] like Figure 1 、 Figure 2 、 Figure 6 and Figure 7As shown, the fixed adjustment component 3 includes a base 11, a driving rod 12, a support seat 13 and a hydraulic device 14. The base 11 is arranged on the reinforcement layer 2. The base 11 is arranged in an inverted L shape and a movable groove 15 is provided on the base 11. The driving rod 12 is movably arranged in the movable groove 15 through a rotating shaft. One end of the driving rod 12 is arranged in the movable groove 15, and the other end of the driving rod 12 is arranged outside the movable groove 15 and is arranged close to the wellbore 1. The support seat 13 is arranged at the upper end of the base 11, and the fixed end of the hydraulic device 14 is arranged on the support seat 13. The movable end of the hydraulic device 14 movably passes through the support seat 13 and is arranged in the movable groove 15. The movable end of the hydraulic device 14 is arranged above one end of the driving rod 12, and the connecting member 4 is movably arranged at the other end of the driving rod 12.

[0029] In this embodiment, the driving rod 12 is pressed by synchronously controlling the movable end of the hydraulic device 14, thereby driving the other end of the driving rod 12 to rise. The other end of the driving rod 12 drives the upper and lower ends of the guide rail 5 to synchronously move away from the shaft 1 and closer to the car 6 through the connecting member 4, thereby maintaining a safe distance when the side wall of the shaft 1 is deformed.

[0030] 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. A slide groove 18 is provided on the upper beam 8 and the lower beam 9. The side wall of the slide groove 18 is provided with a wire hole 19. The sliding base assembly 16 is slidably arranged on the slide groove 18, and the elastic guide assembly 17 is fixedly arranged on the sliding base assembly 16.

[0031] In this embodiment, when the other end of the driving rod 12 drives the upper and lower ends of the guide rail 5 to synchronously move away from the shaft 1 and closer to the car 6 through the connecting member 4, the guide rail 5 squeezes the sliding base assembly 16 and slides on the slide groove 18 close to the car 6, and the guide rail 5 moves between the two groups of upper beams 8 and the two groups of lower beams 9.

[0032] like Figure 3 、 Figure 4 and Figure 5 As shown, the sliding base assembly 16 includes a sliding plate 20, a slider 21, a sliding rod 22, a strong spring 23 and a guide base 24. The slider 21 is arranged on the lower wall of the sliding plate 20. The sliding plate 20 is movably arranged in the sliding groove 18 through the slider 21. The sliding rod 22 is movably arranged through the slider 21 and the wire hole 19. One end of the strong spring 23 is arranged against the side wall of the sliding groove 18, and the other end of the strong spring 23 is arranged against the slider 21. The guide base 24 is fixed on the sliding plate 20, and the elastic guide assembly 17 is fixed on the guide base 24.

[0033] When the guide rail 5 squeezes the movable guide assembly 10, the sliding plate 20 slides in the slide groove 18 through the slider 21 to squeeze the strong spring 23 to contract. Under the elastic recovery force of the strong spring 23, the elastic guide assembly 17 on the guide base 24 can still maintain a movable connection with the guide rail 5, thereby continuing to guide the movement direction of the car 6.

[0034] like Figure 4 and Figure 5 As 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. The bracket 25 is provided with two groups, and the two groups 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 the two groups of support rods 26, and the guide wheel 28 is fixed on the forward rotation shaft 27. The guide rail 5 is arranged in a T-shape. The wheel 28 is movably connected to the main wall of the guide rail 5, the side bracket 29 is fixed on the guide base 24, and the side bracket 29 is arranged close to the outer side of the guide base 24. The lower end of the side support rod 30 is movably connected to the side bracket 29, and the side rotating shaft 31 is movably connected to the side support rod 30. The central axis of the side rotating shaft 31 is perpendicular to the central axis of the positive rotating shaft 27. The side guide wheel 32 is fixed on the side rotating shaft 31, and the side guide wheel 32 is movably connected to the side wall of the guide rail 5.

[0035] 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 up and down lines.

[0036] like Figure 4 and Figure 5 As shown, a fixing rod 33 is provided on the guide base 24, and the fixing rod 33 is provided at the intersection of the central axis of the bracket 25 and the central axis of the side bracket 29. A protrusion 34 is provided on the upper end of the support rod 26 and the side support rod 30, and the protrusion 34 is arranged close to one side of the bracket 25 and the side bracket 29. A limiting rod 35 is movably passed through the protrusion 34, and one end of the limiting rod 35 is movably passed through the fixing rod 33. A limiting block 1 is provided at both ends of the limiting rod 35. 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, and 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.

[0037] like Figure 4 and Figure 5As shown, an auxiliary rod 36 is movably provided on the protrusion 34, one end of the auxiliary rod 36 is movably provided through the fixed rod 33, and a weak spring 37 is provided on the other end of the auxiliary rod 36. Limit blocks 2 are provided at both ends of the auxiliary rod 36, one end of the weak spring 37 is set against the limit block 2, 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 produce 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, and 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 up and down movement of the car 6.

[0038] In this embodiment, the initial tension of the weak spring 37 is less than the initial tension of the strong spring 23 and is less than the maximum tension of the weak spring 37. When the movable end of the hydraulic device 14 is controlled to press the drive rod 12, thereby driving the other end of the drive rod 12 to rise, the other end of the drive rod 12 drives the upper and lower ends of the guide rail 5 to synchronously move away from the shaft 1 and closer to the car 6 through the connecting member 4, and the guide rail 5 squeezes the movable guide assembly 10. When the guide rail 5 greatly squeezes the guide wheel 28, the weak spring 37 is first forced to contract. 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 and squeeze the strong spring 23 to contract. Under the joint 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 preventing the deformation of the shaft 1 from affecting the normal operation of the car 6.

[0039] like Figure 1 、 Figure 2 and Figure 3 As shown, a traction rope 38 is provided on the top of the car 6 for pulling the elevator car 6 up and down.
