Description

Technical Field

[0001] The invention relates to the technical field of mine construction, and in particular to a horizontal inclined shaft track safety vehicle blocking device. Background Art

[0002] The car stopper, also known as the parking device, is one of the important facilities in the coal mine transportation system. It is a device to prevent the mine car from running away. It is usually installed at the top of the slope. On the one hand, it limits the mine car to stay in the specified position, and on the other hand, it is used to prevent the occurrence of runaway accidents. It is often used in conjunction with equipment such as pushers, dumpers, crawlers, cages, and dispatching winches.

[0003] The patent document with application number: CN201921148350.7 discloses a car blocker for inclined tunnel construction, including a car blocker device body, a car blocker, a monitoring platform and a mounting plate. The car blockers are fixedly connected to the top sides of the car blocker device body, and the middle of the car blocker is fixedly connected to the fixed platform. The top sides of the fixed platform are fixedly connected to fixed frames, and the middle of one end of the fixed frame is overlapped and connected to a motor. The bottom end of the car blocker device body is fixedly connected to the mounting plate, and the top of the mounting plate is embedded with four card slots around the four sides. The card slots reflect the adjustability of the utility model. The spring column can limit the sliding and running mine car, and the spring column can effectively reduce the shock of the mine car, which plays a certain protective role. The car blocker is easy for the staff to adjust and use, which reflects the practicality of the utility model. The monitor can achieve the effect of automatically adjusting the blocked track, which reflects the monitoring and protection of the utility model, and has broad application prospects in the future.

[0004] However, it still has the following shortcomings in practical application:

[0005] First, the safety is poor, because the device in the above-mentioned comparative document directly blocks the wheels when intercepting the mine car, which will cause the wheels of the mine car to be subjected to a relatively strong impact, which may easily cause damage to the wheels and axles of the mine car, and also easily cause the mine car to overturn or derail on the track.

[0006] Second, the release effect is not good because it is aimed at blocking the wheels of the mine car. If the mine car needs to be released, if the mine car itself is heavy and is on an inclined track, it is difficult for the motor in the above-mentioned comparative document to drive the spring column to rotate and move the block away from the track.

[0007] Third, the interception effect is not good, because the device in the above-mentioned comparative document cannot carry out targeted blocking according to the speed of the mine car when blocking the mine car, and thus cannot intercept the mine car quickly and stably.

[0052] In order to be able to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0053] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0054] A horizontal inclined shaft track safety car stopper device in this embodiment, referring to Figure 1-15 : The car stopper assembly 1000, the reset assembly 2000 and the limit assembly 3000. (I)

[0056] The vehicle-blocking assembly 1000 includes a hanging unit 1100 disposed at the bottom of the mine car 4000 and a deceleration unit 1200 disposed in the middle of the track 5000.

[0057] (One-one)

[0058] The hanging unit 1100 includes a reinforcing plate 1101 disposed in the middle of the bottom end of the mine car 4000 and a reinforcing block 1102 disposed in the middle of the bottom end of the reinforcing plate 1101. Grooves 1103 are formed at both ends of the reinforcing block 1102 along the front and rear directions of the mine car 4000, and the grooves 1103 penetrate along the left and right ends of the mine car 4000, and the grooves 1103 are completely lower than the axle 4001 of the mine car 4000 in the vertical direction. This can ensure that the deceleration unit 1200 will not be interfered by the axle 4001 when cooperating with the hanging unit 1100, that is, ensure the safe driving of the mine car 4000 on the track 5000.

[0059] (One-two)

[0060] The deceleration unit 1200 includes a bottom plate 1201, a first guide rail plate 1202, a second guide rail plate 1203, a first slider 1204, a guide rod 1205, a second slider 1206, a deceleration spring 1207, a T-shaped docking block 1208, a first screw rod 1209 and a first motor 1210. The bottom plate 1201 is fixedly installed on the ground at the lower end of the track 5000. A set of first guide rail plates 1202 are symmetrically arranged on the upper surface of the bottom plate 1201 along the direction of the travel of the track 5000. The travel direction of the first guide rail plate 1202 is perpendicular to the travel direction of the track 5000. The number of the second guide rail plates 1203 is two. The bottom of the second guide rail plate 1203 is provided with first sliders 1204 with the same number as the first guide rail plates 1202 and corresponding one by one. The first sliders 1204 are slidably connected to the corresponding first guide rail plates 1202. Guide rods 1205 in the same direction as their travel directions are provided in the second guide rail plates 1203. Second sliders 1206 are slidably connected in the second guide rail plates 1203. Through grooves matching the guide rods 1205 are formed in the second sliders 1206. Deceleration springs 1207 matching the guide rods 1205 are sleeved on the rod bodies of the guide rods 1205 at both ends of the second sliders 1206. The two ends of the deceleration springs 1207 are respectively fixedly connected to the second sliders 1206 and the second guide rail plates 1203. T-shaped docking blocks 1208 are fixedly installed at the tops of the second sliders 1206. A first screw rod 1209 is rotatably connected to any one of the first guide rail plates 1202. The first screw rod 1209 is driven to rotate by a first motor 1210 disposed on the bottom plate 1201 and outside the first guide rail plate 1202. Two threads in opposite directions are symmetrically provided on the rod body of the first screw rod 1209 inside the first guide rail plate 1202. Threaded through grooves matching the corresponding threads are provided on the two first sliders 1204 on the first guide rail plate 1202.

[0061] (1-3)

[0062] To ensure that the component only intercepts the mine car 4000 when it is in the closed track 5000, the following cooperation relationships need to be satisfied simultaneously between the deceleration unit 1200 and the hanging unit 1100:

[0063] ①. The height of the block at the upper end of the T-shaped docking block 1208 in the vertical direction is between the upper side wall and the lower side wall of the groove 1103.

[0064] ②. When the two second guide plates 1203 are respectively located at both ends of the stroke of the first guide plate 1202, the projections of the T-shaped docking block 1208 and the reinforcing block 1102 in the direction of the track 5000 stroke are completely independent.

[0065] ③. When the two second guide plates 1203 are both close to the middle of the stroke of the first guide plate 1202, the projection of the block at the upper end of the T-shaped docking block 1208 in the direction of the track 5000 stroke is completely inside the projection of the groove 1103 in the direction of the track 5000 stroke.

[0066] (1-4)

[0067] Since the speed of the mine car 4000 when traveling on the track 5000 is not completely consistent, and at the same time the inertia of the mine car 4000 will be different according to its load capacity, however, the stiffness coefficient of the deceleration spring 1207 remains unchanged, then the deceleration spring 1207 cannot well decelerate the mine car 4000 with different vehicle speeds and different load capacities.

[0068] Two telescopic rods 1211 are symmetrically fixed at both ends of the second slider 1206 (and the ends of the telescopic rods 1211 are not fixed to the second guide plate 1203). The central axis of the telescopic rod 1211 is parallel to the central axis of the guide rod 1205. The inside of the telescopic rod 1211 is pre-filled with magnetorheological fluid. Electromagnets 1212 are provided at both ends of the fixed rod of the telescopic rod 1211. A return spring 1213 matching it is also sleeved outside the rod body of the telescopic rod 1211.

[0069] It should be noted that: the magnetic axis of the electromagnet 1212 coincides with the central axis of the telescopic rod 1211, and the magnetic field directions of the two electromagnets 1212 on the same telescopic rod 1211 are the same. The telescopic amount of the telescopic rod 1211 is equal to the telescopic amount of the deceleration spring 1207.

[0070] In this way, a magnetic field of a specified strength can be generated by the electromagnet 1212 (at the same end as the deceleration spring 1207 in the squeezed state), so that the magnetorheological solution is at a specified viscosity, thereby changing the damping coefficient of the telescopic rod 1211, thereby changing the stiffness coefficient of the deceleration spring 1207 in disguised form. (two)

[0072] The reset assembly 2000 is disposed at an outer end of one side of the rail 5000 .

[0073] The reset assembly 2000 includes a third guide plate 2001, a third slider 2002, a second screw 2003, a second motor 2004, a horizontal plate 2005, a fourth guide plate 2006, a fourth slider 2007, a third motor 2008, a third screw 2009, a U-shaped side frame 2010, a mounting box 2011, a driving wheel 2012 and a fourth motor 2013; the third guide plate 2001 is fixedly arranged on the ground outside the track 5000, and the travel direction of the third guide plate 2001 is parallel to the travel direction of the track 5000, the third slider 2002 is slidably connected to the third guide plate 2001, and the third slider 2002 is driven to move by the second screw 2003 and the second motor 2004 matched therewith, and the upper end of the third slider 2002 is fixed with a horizontal plate 2005, and the plate surface at the upper end of the horizontal plate 2005 moves along the track 5000. A group of fourth guide rail plates 2006 are symmetrically provided in the travel direction, the travel direction of the fourth guide rail plates 2006 is perpendicular to the travel direction of the track 5000, and the fourth guide rail plates 2006 are slidably connected with fourth sliders 2007, wherein any fourth guide rail plate 2006 is provided with a third motor 2008 and a third screw 2009 for driving the fourth slider 2007 thereon to move, the top of the fourth slider 2007 close to the track 5000 is fixed on the U-shaped side frame 2010, and the end of the U-shaped side frame 2010 is provided with a mounting box 2011, the side of the mounting box 2011 close to the track 5000 is rotatably connected with a pair of driving wheels 2012, and the side of the mounting box 2011 away from the track 5000 is provided with a fourth motor 2013, and the fourth motor 2013 and the two driving wheels 2012 on the same mounting box 2011 are kept synchronously through chain transmission.

[0074] The central axes of the two driving wheels 2012 on the same mounting box 2011 are at the same distance from the central axes of the wheels 4002 of the mine car 4000 in the vertical direction, and the distance between the central axes of the two driving wheels 2012 at the same vertical height is equal to the distance between the central axes of the two axles 4001 on the mine car 4000.

[0075] The function of the reset component 2000 is to push the mining car 4000 blocked by the vehicle blocking component 1000 backwards.

[0076] It should be noted that in order to ensure that the reset assembly 2000 can precisely push the mine car 4000 backward, a positioning sensor 6000 needs to be set on the fourth slider 2007 in the middle of the horizontal plate 2005 (in this embodiment, the positioning sensor 6000 is an infrared emitter, and an infrared receiver cooperating with it is also provided on the infrared emitter). A pair of positioning marks 6001 (in this embodiment, the positioning marks 6001 are reflective stickers) cooperating with the positioning sensor 6000 are provided on the body in the middle of the mine car 4000.

[0077] It should be noted that the distance between the two positioning marks 6001 in the horizontal direction is equal to the distance between the plane formed by the central axes of the two driving wheels 2012 on the same mounting box 2011 and the central axis of the corresponding wheel 4002. (III)

A pair of clamping plates 3003 are provided at the ends of the motor shaft 3002, and the two clamping plates 3003 at the end of the motor shaft 3002 rotate coaxially and in opposite directions.

[0081] Among them, the function of the limit component 3000 is to stop the mine car 4000 on the track 5000 and at the same time ensure the smoothness of the mine car 4000 during the release process. (IV)

[0083] On the outer end of the side of the track 5000 different from the reset assembly 2000, a control cabinet 7000, a support rod 7001, and a detection device 7002 are also provided.

Detection devices 7002 are provided at the tops of the support rods 7001. The detection device 7002 includes a millimeter-wave radar 7003 and an infrared camera module 7004.

[0084] Among them, the function of the millimeter-wave radar 7003 is to detect the speed of the mine car 4000 on the track 5000, so as to facilitate adjusting the magnetic field intensity generated by the electromagnet 1212. The function of the infrared camera module 7004 is to perform living body detection, so as to prevent the millimeter-wave radar 7003 from misjudging the miners walking on the track 5000 as the mine car 4000. (V)

[0086] The specific working principle of the present invention is as follows:

[0087] (Five - One)

[0088] When the track 5000 is completely unobstructed and open:

[0089] The control cabinet 7000 commands the electromagnet 1212 to cut off the power; commands the first motor 1210 to drive the first screw 1209 to rotate, so that the two second guide rails are separated from each other (at this time, the two deceleration springs 1207 in the second guide rail plate 1203 are in the same state); commands the third motor 2008 to drive the third screw 2009 to rotate, so that the driving wheel 2012 moves away from the track 5000; commands the two double - headed motors 3001 to work, so that all the clamping plates 3003 are in a state parallel to the ground.

[0090] (Five - Two)

[0091] When it is necessary to intercept the mine car 4000:

[0092] First step, the control cabinet 7000 commands the detection device 7002 to start and detect both ends of the track 5000. When the mine car 4000 is detected, the control cabinet 7000 can determine the approaching direction and traveling speed of the mine car 4000.

[0093] Second step, the control cabinet 7000 commands the first motor 1210 to drive the first screw 1209 to rotate, so that the two second guide rail plates 1203 approach each other, that is, the two T - shaped docking blocks 1208 approach each other.

[0094] Third step, the control cabinet 7000 commands the electromagnet 1212 on the side of the second slider 1206 at the front end in the traveling direction of the mine car 4000 to be energized to generate a magnetic field of a specified intensity according to the vehicle speed of the mine car 4000 measured by the detection device 7002.

[0095] Fourth step, the mine car 4000 travels along the track 5000 to the car - blocking assembly 1000, and the two T - shaped docking blocks 1208 are clamped in the corresponding grooves 1103, so as to decelerate the mine car 4000 through the deceleration springs 1207. During this process, the control cabinet 7000 will monitor the vehicle speed of the mine car 4000 in real - time through the detection device 7002 and fine - tune the magnetic field intensity generated by the electromagnet 1212 in real - time, so as to ensure that the mine car 4000 can stop quickly and smoothly.

[0096] It should be noted that: due to the unique design of the car - blocking assembly 1000 in the present invention, compared with the traditional car - blocking equipment that uses a block set on the track 5000 to block the wheels 4002, the present invention can effectively avoid the danger of derailment or overturning of the mine car 4000 when intercepting the mine car 4000.

[0097] (Five - Three)

[0098] When it is necessary to reset the mine car 4000:

[0100] Second step, the control cabinet 7000 instructs the third motor 2008 to drive the third screw 2009 to rotate, so that the U-shaped side frame 2010 approaches the mine car 4000 and makes the driving wheel 2012 contact the mine car 4000.

[0101] Third step, the control cabinet 7000 instructs the second motor 2004 to drive the second screw 2003 to rotate, so as to force the U-shaped side frame 2010 to move in the direction of the approaching mine car 4000. And during this process, the control cabinet 7000 also instructs the fourth motor 2013 to start, so that the driving wheel 2012 drives the wheel 4002 to reverse, thereby further improving the stability of the mine car 4000 when reversing.

[0102] Fourth step, the control cabinet 7000 instructs the reset component 2000 to reverse the mine car 4000 along the track 5000 to a specified position (that is, the projection of the central axis of the motor shaft 3002 of the double-headed motor 3001 at one end of the mine car 4000 in the approaching direction of the mine car 4000 on the ground coincides with the projection of the central axis of the axle 4001 at the front end in the driving direction of the mine car 4000 on the ground) (and at this time, the T-shaped docking block 1208 and the reinforcing block 1102 do not contact each other).

[0103] (Five - Four)

[0104] When it is necessary to park the mine car 4000:

[0105] The control cabinet 7000 instructs the double-headed motor 3001 at one end of the mine car 4000 in the approaching direction of the blocking component 1000 to start, so that the two clamping plates 3003 at the end of the motor shaft 3002 rotate upward and clamp the wheel 4002 of the mine car 4000, thereby realizing the parking of the mine car 4000.

[0106] It should be noted that: in order to further ensure the safety of the present invention when parking the mine car 4000, during this process, the two T-shaped docking blocks 1208 in the blocking component 1000 still remain in a close state, and all the electromagnets 1212 are in a power-off state.

[0107] (Five - Five)

[0108] When it is necessary to release the mine car 4000:

[0109] First step, the control cabinet 7000 instructs the first motor 1210 to drive the first screw 1209 to rotate, so that the two second guide rails are separated from each other.

[0110] Second step, the control cabinet 7000 instructs the double-headed motor 3001 at one end in the approaching direction of the mine car 4000 to start, so that the two clamping plates 3003 on the motor shaft 3002 rotate away from each other, thereby releasing the originally held wheel 4002.
