However, in recent years, elevator safety accidents have occurred continuously, and the relevant protection measures have not been improved, often causing heavy casualties. When the elevator falls, people and the elevator accelerate downward together. When it hits the ground, because the elevator touches the bottom, the speed changes from extremely high to zero in a very short time, and people are injured or even killed due to the huge impact force. Similarly, when a fault occurs in the elevator lift and it rises rapidly, people and the elevator accelerate upward together. After hitting the top, the speed changes from extremely high to zero in a very short time, and the huge impact force will still cause injury or even death. Summary of the Invention

[0028] See Figures 1 to 7 , the present application provides an elevator 200 with an anti-overrun emergency device, which is arranged in an elevator shaft, and a lifting mechanism is arranged in the elevator shaft for lifting or lowering the elevator 200, including: a slide rod 100, an elevator 200 and an anti-overrun mechanism 300. The slide rod 100 is arranged on both sides of the elevator shaft; mounting boxes 210 are symmetrically arranged on both sides of the elevator 200. Through holes are arranged at opposite ends of the mounting boxes 210 in the vertical direction. The slide rod 100 passes through the through holes, and the elevator 200 can slide up and down along the slide rod 100; the anti-overrun mechanism 300 includes a monitoring component 310, a power supply component 320 and two induction coils 400. The monitoring component 310 is arranged on the top of the elevator 200 and is electrically connected to the power supply component 320 for monitoring the relative speed of the elevator 200; the power supply component 320 is arranged on the top of the elevator 200. The two induction coils 400 are respectively arranged in the mounting boxes 210 and surround the slide rod 100, and one ends of the two induction coils 400 are respectively connected to the power supply component 320, and the other ends are connected to each other.

[0029] Specifically, the sliding rod 100 is made of, but not limited to, materials such as copper or aluminum. Preferably, it is a copper sliding rod 100. The lifting mechanism uses a common driving device of the elevator 200 (the specific structure will not be elaborated here). The installation box 210 is a cuboid box with an opening on one side. The installation box 210 is made of a frame made of insulating materials such as, but not limited to, wood or rubber. Through holes are provided on the upper and lower sides of the installation box 210. The sliding rod 100 passes through the through holes and is respectively connected to the upper and lower ends of the elevator shaft at both ends.

[0030] The monitoring component 310 in the anti-overrun mechanism 300 is made of, but not limited to, instruments such as a speedometer or a speed monitor for monitoring the relative speed of the elevator 200. The monitoring component 310 is arranged on the top of the elevator 200. The power supply component 320 is made of, but not limited to, power supply devices such as rechargeable batteries or direct current, and is arranged on one side of the monitoring component 310. The monitoring component 310 is electrically connected to the power supply component 320, and through the electrical connection, the monitoring component 310 can monitor the relative speed of the elevator 200 in real time. The induction coil 400 is made of, but not limited to, conductors such as copper wire or aluminum wire. Both induction coils 400 include a winding part, a connecting part, and a power connection part. The power connection parts of the two induction coils 400 are respectively connected to the positive and negative poles of the power supply component 320, and a switch is provided at the connection point. The switch is electrically connected to the monitoring component 310. The connecting parts of the two induction coils 400 are connected to form an integral body (preferably a wire, with both ends connected to the positive and negative poles of the power supply component 320 and arranged around the circumference of the elevator 200). The winding part of the induction coil 400 is spirally wound around the circumference of the sliding rod 100, and both ends of the winding part of the induction coil 400 are detachably connected to the upper and lower sides of the installation box 210 by means of buckles. The diameter of the spiral part is not less than the diameter of the sliding rod 100. A transformer is arranged on one side of the switch to change the current and voltage.

[0031] Further, during the operation of the elevator 200, the power supply component 320 provides electrical energy for the monitoring component 310. The monitoring component 310 monitors the speed of the elevator 200 (the rising or falling speed of the elevator 200 can be set according to the standard specifications. Taking 2 m / s as an example). When a fault occurs in the elevator 200 and the rising or falling speed exceeds 2 m / s, the switch at the power connection part of the induction coil 400 closes. The power supply component 320 provides electrical energy for the induction coil 400. The transformer changes the current and voltage, and the winding part of the induction coil 400 forms a magnetic field due to the passing of the current. At this time, when the elevator 200 moves along the sliding rod 100, the elevator 200 drives the installation box 210 and the power supply component 320 to continuously rise, causing the sliding rod 100 to continuously cut the magnetic field formed by the induction coil 400 (when cutting the magnetic field, the magnetic field will generate a repulsive force opposite to the cutting direction). The magnetic field exerts a reverse force on the sliding rod 100, thereby slowing down the rising speed of the elevator 200. And by continuously adjusting the transformer to change the current and voltage until the elevator 200 stops moving.

[0032] The technical solution of an elevator 200 with an anti-overrun emergency device adopted by this application can achieve the following beneficial effects: By setting the sliding rod 100, the induction coil 400 and the power supply component 320, the induction coil 400 forms a magnetic field under the power transmission of the power supply component 320. The sliding rod 100 continuously cuts the magnetic field to reduce the moving speed of the elevator 200 by the repulsive force of the magnetic field. At the same time, by changing the current voltage, the repulsive force of the magnetic field is changed until the repulsive force slows down the moving speed of the elevator 200 to a safe speed or stops, thus solving the problem that the elevator 200 falls or the overrun speed of the elevator 200 is too fast, resulting in the elevator 200 and people accelerating together, and people being injured or even killed due to landing or overrun.

[0033] See Figures 4 to 7 In the first implementation scheme, the power supply component 320 includes a rotating disk 324, a transmission wheel 327 and a storage battery 323. The rotating disk 324 is rotatably connected to the top of the elevator 200. The storage battery 323 is detachably connected to the rotating disk 324, and the storage battery 323 is in contact connection with both ends of the induction coil 400; the transmission wheel 327 is hinged at both ends of the elevator 200 where the installation box 210 is provided, and is in transmission connection with the rotating disk 324. The transmission wheel 327 is electrically connected to the monitoring component 310.

[0034] Specifically, a clamping member is provided on the upper end surface of the rotating disk 324. The storage battery 323 is detachably connected to the upper end surface of the rotating disk 324 by clamping (or can also be connected by bolts, etc.). The lower end surface of the rotating disk 324 is rotatably connected to the top of the elevator 200 by means of a bearing rotating shaft; a contact plate is provided at the power connection part of the induction coil 400, and the contact plate is in contact with the positive and negative electrodes of the storage battery 323; the transmission wheel 327 is arranged at both ends of the elevator 200 where the installation box 210 is provided by means of a connecting rod 3271. The transmission wheel 327 is not limited to wheels such as rubber wheels and vehicle wheels. The transmission wheel 327 is in rotational contact with the side wall of the elevator shaft. The transmission wheel 327 is coaxially provided with a pulley. One of a gear, a rack, a friction wheel, etc. is provided on the lower end surface of the rotating disk 324; the pulley is transmitted to the rotating disk 324 in the form of a belt, and the lower end surface of the rotating disk 324 is rotated by one of a gear, a rack, a friction wheel, etc.; the rotation of the rotating wheel drives the rotating disk 324 to rotate, so as to realize the connection and disconnection between the storage battery 323 and the induction coil 400.

[0035] One end of the transmission wheel 327 is connected in a hinged manner (in the initial state, the angle between the connecting rod 3271 of the transmission wheel 327 and the side wall of the elevator 200 is an acute angle, and the transmission wheel 327 does not contact the side wall of the elevator shaft). When the data monitored by the monitoring component 310 exceeds the threshold, the connecting rod 3271 of the transmission wheel 327 rotates from the initial state to a vertical state (in the vertical state, the angle between the connecting rod 3271 of the transmission wheel 327 and the side wall of the elevator 200 is a right angle, and the transmission wheel 327 contacts the side wall of the elevator shaft). At the same time, the transmission wheel 327 rotates due to the movement of the elevator 200, thereby driving the rotating disk 324 to rotate, and the operation is simpler and more convenient.

[0036] In the above scheme, one side of the transmission wheel 327 is slidably connected with a stretching member 3272, one end of the stretching member 3272 is slidably connected to the side wall of the elevator 200 where the installation box 210 is provided, and the other end is hinged to the transmission wheel 327, and the stretching member 3272 is electrically connected to the monitoring component 310, and the stretching member 3272 is used to drive the transmission wheel 327 to rotate along the hinge with the side wall of the elevator 200.

[0037] Specifically, a tension piece 3272 is hinged on the connecting rod 3271 of the transmission wheel 327, and a spring buckle 3273 and a protrusion are provided at one end of the tension piece 3272. The elevator 200 is provided with slide grooves on both sides of the installation box 210. The protrusion is limited by the slide groove and the protrusion can slide up and down along the slide groove. The spring buckle 3273 can move back and forth in the direction perpendicular to the side wall of the elevator 200, and the spring buckle 3273 is electrically connected to the monitoring component 310; a tension spring 3274 is provided at the bottom of the slide groove, and the other end of the tension spring 3274 is connected to the bottom of the tension piece 3272. A pit is provided on the slide groove. When the connecting rod 3271 is in the initial state, the spring buckle 3273 is limited by the pit and the tension spring 3274 is compressed.

[0038] When the monitoring data of the monitoring component 310 exceeds 2m / s, the spring buckle 3273 moves to the side away from the side wall of the elevator 200 and leaves the pit, and the compressed tension spring 3274 pushes the tension member 3272 to slide upward, thereby driving the connecting rod 3271 to change from the initial state to the vertical state, so that the transmission wheel 327 contacts the side wall of the elevator 200 and rotates, making the operation more convenient.

[0039] Furthermore, the power supply assembly 320 includes a guide wheel 328 , which is disposed on the top of the elevator 200 and is rotationally matched with the lower end surface of the rotating disk 324 and is transmission-connected to the transmission wheel 327 .

[0040] The guide wheel 328 includes a first bevel gear 3281, a second bevel gear 3282 and a spur gear 3283. The first bevel gear 3281 (the end of the first bevel gear 3281 is a pulley, and the other end is a bevel gear. The pulley and the bevel gear can also be coaxially arranged) is connected to the top of the elevator 200 by means of a fixing plate and a rotating shaft. The first bevel gear 3281 is connected to the driving wheel 327 by belt drive, so as to realize the rotation of the first bevel gear 3281 (the rotation direction is the same as that of the driving wheel 327, both rotating in the vertical direction); the second bevel gear 3282 is rotatably connected to the top of the elevator 200 by a rotating shaft, and the second bevel gear 3282 (the lower end of the second bevel gear 3282 is a pulley, and the upper end is a bevel gear. The pulley and the bevel gear can also be coaxially arranged) meshes with the first bevel gear 3281 (the rotation direction changes to horizontal rotation); the spur gear 3283 (the lower end of the spur gear 3283 is a pulley, and the upper end is a common gear. The pulley and the common gear can also be coaxially arranged) is also rotatably connected to the top of the elevator 200 by means of a rotating shaft, and the spur gear 3283 is connected to the second bevel gear 3282 by belt drive. The spur gear 3283 meshes and drives with the rotating disc 324, so as to realize the rotation of the rotating disc 324; by setting the transmission steering of the guide wheel 328, the transmission from the driving wheel 327 to the rotating disc 324 is realized, the operation is simpler and more convenient, and the driving wheel 327 and the first bevel gear 3281 are connected by belt drive, solving the problems that the gear meshing is easy to get stuck and damaged due to the rotation of the position of the driving wheel 327.

[0041] In the above solution, a split gear 325 and a limiting member 326 are arranged on the lower end surface of the rotating disc 324. The upper end surface of the split gear 325 is fixedly connected to the rotating disc 324. The limiting member 326 is arranged on both sides of the teeth of the split gear 325. The guide wheel 328 meshes with the split gear 325 and is in limiting cooperation with the limiting member 326.

[0042] Specifically, a missing gear 325 is provided on the lower end surface of the rotating disk 324 (the missing gear 325 includes a tooth part and a missing tooth part, and the first and last teeth of the tooth part are the starting tooth and the ending tooth respectively). The center of the missing gear 325 coincides with and is fixed to the center of the rotating disk 324. A limiting member 326 is provided on the missing gear 325. The missing gear 325 meshes with the spur gear 3283 in the guide wheel 328. The driving wheel 327 drives the first bevel gear 3281 to rotate in the vertical direction through a belt. The second bevel gear 3282 rotates in the horizontal direction under the rotation of the first bevel gear 3281. The spur gear 3283 connected to the second bevel gear 3282 by a belt rotates accordingly, thereby driving the missing gear 325 to rotate. When the spur gear 3283 meshes with the tooth part, the rotating disk 324 rotates. When it rotates to the missing tooth part, the positive and negative electrodes of the storage battery 323 contact and communicate with both ends of the induction coil 400. The limiting member 326 restricts its rotation, thereby realizing the rotation of the rotating disk.

[0043] In the above solution, the limiting member 326 includes an annular rod 3261, two limiting teeth 3262 and two return springs 3263. Both ends of the annular rod 3261 are fixedly connected to both sides of the tooth of the missing gear 325. One ends of the two return springs 3263 are respectively fixedly connected to both sides of the annular rod 3261, and the other ends are respectively fixedly connected to one of the limiting teeth 3262. The return spring 3263 and the limiting tooth 3262 are both penetrated by the annular rod 3261 and can slide along the extending direction of the annular rod 3261.

[0044] Specifically, a slider is provided on the lower end surface of the rotating disk 324, and a semi-circular chute is provided on the top of the elevator 200. The slider is in limit fit with the chute to make the rotating disk 324 more stable and at the same time limit the rotation angle of the rotating disk 324. Both ends of the annular rod 3261 are respectively fixedly connected to the starting tooth and the ending tooth of the missing gear 325. The two limiting teeth 3262 are respectively connected to one side of the starting tooth and the ending tooth through the return springs 3263. When the spur gear 3283 meshes with the missing gear 325 and rotates to the limiting tooth 3262, the spur gear 3283 drives the limiting tooth 3262 to compress the return spring 3263 and move towards the gear part, thereby completing the limitation of the missing gear 325. On the contrary, when the spur gear 3283 rotates in the reverse direction, it pushes the limiting tooth 3262 to move away from the gear part and drives the missing gear 325 to rotate, so that the gear part meshes with the spur gear 3283 and rotates to the other limiting tooth 3262 to achieve limitation. By providing the limiting member 326, the problem that the power connection part between the storage battery 323 and the induction coil 400 is separated due to the rotation of the missing gear 325 is solved.

[0045] The initial state of the missing gear 325 (corresponding to the initial position of the battery 323 at the upper end of the rotating disk 324, at this time the connection line of the positive and negative poles of the battery 323 is perpendicular to the connection line of the power connection parts of the two induction coils 400) is that the flat gear 3283 meshes with the middle part of the missing tooth part of the missing gear 325. When rising, the flat gear 3283 drives the missing gear 325 to rotate from the middle to the starting tooth, and the battery 323 rotates clockwise; conversely, when descending, the flat gear 3283 drives the missing gear 325 to rotate from the middle to the end tooth, and the battery 323 rotates counterclockwise; by changing the direction, the direction of the magnetic field generated by the induction coil 400 is changed, so as to more effectively reduce the moving speed of the elevator 200.

[0046] See Figure 3 For the second embodiment, the power supply assembly 320 includes a first battery pack 330, a second battery pack 340 and two two-way switches 350. The first battery pack 330 and the second battery pack 340 are arranged side by side; the two two-way switches 350 are respectively arranged at both ends of the positive and negative poles of the first battery pack 330 and the second battery pack 340, and are located at the connection part between the first battery pack 330 and the second battery pack 340; the two two-way switches 350 are respectively connected to one end of the two induction coils 400, and the two two-way switches 350 are connected by an insulating plate. The two-way switch 350 is used to switch the positive and negative poles of the induction coil 400.

[0047] Two frames are arranged side by side on the rotating disk 324, and the first battery pack 330 and the second battery pack 340 are detachably connected in the frames, and the positive and negative poles of the first battery pack 330 and the second battery pack 340 are exactly opposite. Two-way switches 350 are arranged at both ends of the frame. The power connection part of the two-way switch 350 is connected to the power connection part of the induction coil 400, and the two two-way switches 350 are connected by an insulating plate, so as to realize that the two two-way switches 350 simultaneously contact the positive and negative poles of the first battery pack 330 or the second battery pack 340; when the elevator 200 moves upward at a speed of more than 2 m / s, by driving the two-way switch 350 to close to the side of the first battery pack 330, a magnetic field is formed to reduce the rising speed of the elevator 200; conversely, when the elevator 200 moves downward at a speed of more than 2 m / s, by driving the two-way switch 350 to close to the side of the second battery pack 340, a magnetic field is formed to reduce the descending speed of the elevator 200; the problem that it is difficult to change the direction of the magnetic field when the elevator 200 moves up and down is solved; the two-way switch 350 can be toggled manually or by a motor.

[0048] See Figures 1 to 7In the above solution, for the sake of convenient operation, the preferred solution is that the power supply component 320 further includes a forward and reverse motor 360. The fixed end of the forward and reverse motor 360 is connected to the top of the elevator 200. The shaft extension end of the forward and reverse motor 360 is connected to the two-way switch 350. And the forward and reverse motor 360 is electrically connected to the first battery pack 330 and / or the second battery pack 340 and the monitoring component 310 respectively, and is used to drive the two-way switch 350 to rotate left and right.

[0049] A circuit board is arranged at one end of the forward and reverse motor 360. The circuit board controls the forward and reverse rotation and start and stop of the forward and reverse motor 360, and is electrically connected to the monitoring component 310. The monitoring component 310 includes a tachometer and a direction sensor. The tachometer is used to start and stop the forward and reverse motor 360, and the direction sensor is used to control the rotation direction of the forward and reverse motor 360. The forward and reverse motor 360 is connected to the two-way switch 350. Preferably, gear meshing is used. By different diameters of the gears, the closing speed of the two-way switch 350 is adjusted. The operation is simpler and more convenient.

[0050] In the above two implementation solutions, a power detector 322 is arranged on one side of the power supply component 320. The power detector 322 is electrically connected to the power supply component 320 and is used to detect the power of the power supply component 320.

[0051] The power detector 322 is arranged on the top of the elevator 200 and is used to detect the power of the power supply component 320. And the power detector 322 is provided with a display screen. The display screen extends into the elevator 200. And both ends of the power detector 322 are connected to the power supply component 320 and are powered by the power supply component 320. By observing the remaining power of the power supply component 320 on the display screen, replacement, charging and maintenance are more convenient.

[0052] Further, a relay is arranged at the charging port of the power supply component 320. The relay is electrically connected to the power detector 322 and the power supply component 320 respectively and is used to control the charging and power-off of the power supply component 320.

[0053] A relay is arranged at the charging port of the power supply component 320. The relay is electrically connected to the power detector 322. When the remaining power of the power detector 322 reaches the predicted value, the relay is connected through manual or electrical signal, so that the power supply component 320 is charged through the power supply. When the charging is completed, the relay automatically disconnects (specifically, such as an electric vehicle charging pile, which automatically cuts off the power when the battery is fully charged), so as to ensure that the power supply component 320 always has sufficient power and the operation is simpler and more convenient.

[0054] The specific working process (the first implementation scheme) is as follows: when the elevator 200 is operating normally at a speed of less than 2 m / s, the connecting rods 3271 of the storage battery 323, the missing gear 325, and the transmission wheel 327 are all in their initial positions; the monitoring component 310 monitors in real time. When the ascending or descending speed of the elevator 200 exceeds 2 m / s, the spring buckle 3273 disengages from the pit, and the stretching member 3272 slides upward along the side wall of the elevator 200 under the push of the stretching spring 3274, causing the connecting rod 3271 to be converted from the initial position to the vertical position. The transmission wheel 327 contacts the side wall of the elevator shaft and drives the first bevel gear 3281 and the second bevel gear 3282 to rotate, so that the flat gear 3283 drives the missing gear 325 to rotate towards the starting teeth or the ending teeth, and thus the rotating disk 324 drives the positive and negative electrodes of the storage battery 323 to contact and communicate with the induction coil 400, forming a magnetic field and reducing the ascending or descending speed of the elevator 200.

[0055] The above-described embodiments only represent the device layout modes of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application; it should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several adjustments and improvements can still be made, and these all belong to the protection scope of the present application; therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
