Description

Technical Field

[0001] This invention relates to the field of elevator anti-runaway device technology, specifically to an elevator anti-runaway device and its usage method. Background Technology

[0002] An elevator is a permanent transportation device that serves several specific floors within a building, with its car moving between at least two rigid guide rails perpendicular to the horizontal plane or at an angle of inclination less than 15° to the vertical. There are also escalators, where steps are mounted on a continuous track and run continuously; these are commonly known as moving walkways or automatic stairs. They are fixed lifting devices serving designated floors. A vertical elevator has a car that runs between at least two rigid guide rails that are vertical or at an angle of inclination less than 15°. The size and structure of the car facilitate passenger entry and exit or loading and unloading of goods. Conventionally, regardless of its drive method, elevator is used as a general term for vertical transportation tools within a building.

[0003] The elevator anti-runaway device and manufacturing method disclosed in application number "CN111689331B" includes a steel structure elevator shaft, a car slidably installed in the steel structure elevator shaft, and a device installed on the top or bottom of the car to prevent accidental movement of the elevator car. The device for preventing accidental movement of the elevator car includes a bracket assembly, with a first driving component installed at one end of the bracket assembly and a second driving component installed at the other end of the bracket assembly. This invention has the following advantages: when the electronic control unit A determines that the car speed is zero, it controls the first and second electric push rods to extend. Rectangular steel A and rectangular steel B are respectively supported on the lower flanges of the side wall fixed beams A and B of the steel structure elevator shaft, realizing mechanical protection measures. Therefore, this invention can effectively eliminate the safety hazards caused by accidental movement of the elevator car when passengers enter and exit the elevator. However, this type of elevator anti-runaway device still has the following defects in actual use: During prolonged use, elevator accelerators may wear down, leading to slippage and posing a safety threat to passengers. Furthermore, elevators often lack anti-slippage devices and deceleration mechanisms to slow down and control slippage. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an elevator anti-runaway device and its usage method, solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an elevator anti-runaway device, comprising a sliding rail, a first hydraulic cylinder fixedly connected to the top of one end of the sliding rail, a mounting bracket fixedly connected to one end of the first hydraulic cylinder, a sliding rail fixedly connected to the back of the mounting bracket, and an anti-runaway frame slidably connected to one side of the sliding rail; The top and bottom of the mounting frame are fixedly connected with elastic telescopic springs, the telescopic ends of the two elastic telescopic springs are fixedly connected to one side of the anti-slip frame, the side of the anti-slip frame is fixedly connected with a second hydraulic cylinder, the telescopic end of the second hydraulic cylinder is fixedly connected to one side of the back of the mounting frame, and an anti-slip mechanism is installed on one side of the anti-slip frame.

[0006] Preferably, a movable slide block is slidably connected to the top of the sliding rail, the top of the movable slide block is fixedly connected to the bottom of the anti-slip frame, a deceleration mechanism is fixedly connected to one side of the movable slide block, and a friction mechanism is fixedly connected to the other side of the movable slide block.

[0007] Preferably, the anti-slip mechanism includes a first drive motor fixedly connected to one side of the anti-slip frame. The top of the anti-slip frame is provided with an active turntable and a driven turntable. A transmission shaft is fixedly connected to one side of the anti-slip frame between the active and driven turntables. The active turntable is fixedly connected to the transmission end of the first drive motor, which is fixedly connected to the bottom of the anti-slip frame. The outer side of the active turntable is connected to the outer side of the transmission shaft via a first transmission belt. The outer side of one end of the transmission shaft is connected to the driven turntable via a second transmission belt. One side of the driven turntable is fixedly connected to an anti-slip roller provided on the other side of the anti-slip frame.

[0008] Preferably, the deceleration mechanism includes a second drive motor fixedly connected to one end of the movable slide, a drive gear fixedly connected to the transmission end of the second drive motor, and the outer side of the drive gear meshing with two driven gears movably connected to the top and bottom of one end through a transmission chain. One side of the two driven gears is fixedly connected to an acceleration roller.

[0009] Preferably, the friction mechanism includes a friction seat fixedly connected to the side of the movable slide, two small electric telescopic rods fixedly connected to one side of the friction seat, a small slide fixed to the telescopic end of each small electric telescopic rod, one side of the small slide being slidably connected to a small slide rail fixedly connected to the side of the movable slide, and a friction roller fixedly connected to one end of the small slide.

[0010] A method for using an elevator anti-runaway device, comprising the aforementioned elevator anti-runaway device, and further comprising the following steps: Step 1: The deceleration mechanism drives the drive gear to rotate through the rotation of the second drive motor, which in turn meshes with the two driven gears, facilitating the rotation of the acceleration rollers. This allows for reverse rotation with the elevator and deceleration.

[0011] Step 2: Friction mechanism. By extending and retracting the small electric telescopic rod, the friction rollers on the two small slides are adjusted so that the two friction rollers are in close contact with the elevator, which facilitates the deceleration of the elevator and ensures smooth movement to prevent slippage.

[0012] Compared with the prior art, the beneficial effects of the present invention are: This invention provides an elevator anti-runaway device and its usage method: 1. The rotation of the first drive motor drives the active turntable to rotate, which in turn drives the first transmission belt to rotate, thereby driving the transmission shaft to rotate. The rotation of the transmission shaft facilitates the rotation of the second transmission belt, so that the anti-slip roller on the driven turntable side is close to the elevator for anti-slip treatment.

[0013] 2. The extension and retraction of two small electric telescopic rods facilitates the sliding of the small slide block on the small slide rail, allowing the two friction rollers to fit against the elevator to prevent slippage, increasing the elevator's coefficient of friction, and thus ensuring that the elevator can move smoothly downwards.

[0020] like Figures 1-5 As shown, the present invention proposes an elevator anti-runaway device, which includes a sliding rail 1, a first hydraulic cylinder 101 fixedly connected to the top of one end of the sliding rail 1, a mounting bracket 102 fixedly connected to one end of the first hydraulic cylinder 101, a sliding rail 103 fixedly connected to the back of the mounting bracket 102, and an anti-runaway frame 104 slidably connected to one side of the sliding rail 103. Elastic telescopic springs 105 are fixedly connected to the top and bottom of the mounting bracket 102. The telescopic ends of the two elastic telescopic springs 105 are fixedly connected to one side of the anti-slip frame 104. A second hydraulic cylinder 1011 is fixedly connected to the side of the anti-slip frame 104. The telescopic end of the second hydraulic cylinder 101 is fixedly connected to one side of the back of the mounting bracket 102. An anti-slip mechanism 2 is installed on one side of the anti-slip frame 104.

[0021] In practical use, by setting the hydraulic extension and retraction of the first hydraulic cylinder 101 to push the mounting frame 102, the anti-slip frame 104 on the mounting frame 102 moves buffered on the movable slide 106 under the extension and retraction of the two elastic extension springs 105, and the range of the anti-slip frame 104 is controlled under the traction of the second hydraulic cylinder 1011, so as to protect the elevator from slippage.

[0022] A movable slide block 106 is slidably connected to the top of the sliding rail 1. The top of the movable slide block 106 is fixedly connected to the bottom of the anti-slip frame 104. A deceleration mechanism 3 is fixedly connected to one side of the movable slide block 106, and a friction mechanism 4 is fixedly connected to the other side of the movable slide block 106.

[0023] In practical use, by moving the slide block 106, the anti-slip mechanism 2 on the anti-slip frame 104 can have a buffering force between itself and the elevator, reducing elevator wear.

[0024] The anti-slip mechanism 2 includes a first drive motor 201 fixedly connected to one side of the anti-slip frame 104. The top of the anti-slip frame 104 is provided with an active turntable 202 and a driven turntable 203. A transmission shaft 204 is fixedly connected to one side of the anti-slip frame 104 between the active turntable 202 and the driven turntable 203. The active turntable 202 is fixedly connected to the transmission end of the first drive motor 201, which is fixedly connected to the bottom end of the anti-slip frame 104. The outer side of the active turntable 202 is connected to the outer side of the transmission shaft 204 via a first transmission belt 205. The outer side of one end of the transmission shaft 204 is connected to the driven turntable 203 via a second transmission belt. One side of the driven turntable 203 is fixedly connected to an anti-slip roller 206 provided on the other side of the anti-slip frame 104.

[0025] In practical use, the rotation of the first drive motor 201 drives the active turntable 202 to rotate, and the active turntable 202 drives the first transmission belt 205 to rotate, which in turn drives the transmission shaft 204 to rotate. The rotation of the transmission shaft 204 facilitates the rotation of the second transmission belt, so that the anti-slip roller 206 on the driven turntable 203 side is close to the elevator for anti-slip treatment.

[0026] The deceleration mechanism 3 includes a second drive motor 301 fixedly connected to one end of the movable slide 106. The transmission end of the second drive motor 301 is fixedly connected to a drive gear 302. The outer side of the drive gear 302 is meshed with two driven gears 303 that are movably connected to the top and bottom of one end through a transmission chain. One side of the two driven gears 303 is fixedly connected to the acceleration roller 304.

[0027] In practical use, the rotation of the second drive motor 301 drives the drive gear 302 to rotate, which in turn drives the transmission chain to rotate, thereby causing the two driven gears 303 to rotate. This facilitates the acceleration roller 304 to roll in the opposite direction to the elevator to reduce the elevator speed.

[0028] The friction mechanism 4 includes a friction seat 401 fixedly connected to the side of the movable slide 106. Two small electric telescopic rods 402 are fixedly connected to one side of the friction seat 401. A small slide 403 is fixedly connected to the telescopic end of each small electric telescopic rod 402. One side of the small slide 403 is slidably connected to a small slide rail 404 fixedly connected to the side of the movable slide 106. A friction roller 405 is fixedly connected to one end of the small slide 403.

[0029] In practical use, the extension and retraction of the two small electric telescopic rods 402 facilitates the sliding of the small slide block 403 on the small slide rail 404, allowing the two friction rollers 405 to fit against the elevator to prevent slippage, increasing the elevator's coefficient of friction, and thus ensuring that the elevator can move smoothly downwards.

[0030] A method for preventing elevator cars from slipping out of control includes the following steps: Step 1: The deceleration mechanism 3 drives the drive gear 302 to rotate through the rotation of the second drive motor 301, so that the transmission chain is meshed with the two driven gears 303, which facilitates the rotation of the acceleration roller 304, thereby enabling it to rotate in the opposite direction to the elevator and decelerate.

[0031] Step 2: Friction mechanism 4. By extending and retracting the small electric telescopic rod 402, the friction rollers 405 on the two small slides 403 are adjusted so that the two friction rollers 405 are close to the elevator, which facilitates the deceleration of the elevator and makes the elevator move smoothly to prevent slippage.
