Description

Technical Field

[0001] This utility model relates to the field of cableway equipment technology, specifically a cableway drive wheel anti-reverse device. Background Technology

[0002] Cableways are equipment used for transporting goods or personnel. Aerial passenger transport systems are the main equipment for transporting personnel underground in mines. Accidental reversal of a cableway can cause a major safety accident. In order to prevent accidental reversal of the cableway, an anti-reversal mechanism needs to be installed. The conventional approach is to install a backstop on the power source (motor or hydraulic motor) of the drive unit, intermediate transmission components, or reducer. However, this solution still has shortcomings. When the cableway experiences unexpected situations such as motor or hydraulic motor failure or accidental reversal, or failure of intermediate transmission components or reducer, the drive wheel and traction steel wire rope cannot achieve the anti-reversal function, which poses a major safety hazard. Furthermore, the current technology uses a single backstop, which is still insufficient in preventing reversal. Utility Model Content

[0003] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a cableway drive wheel anti-reverse device.

[0004] The technical solution adopted by this utility model to achieve the above objectives is as follows: A cableway drive wheel anti-reverse device includes a drive motor, a drive unit frame, a drive wheel, a transmission shaft, and a control system. The drive motor is fixedly connected to the drive unit frame, and the drive motor is poweredly connected to the drive wheel through the transmission shaft. It also includes a swing arm, a deviation sensor, and a limiting component. At least one swing arm is rotatably connected to the drive wheel, and a limiting component is provided on one side of the swing arm. The deviation sensor is provided on the drive unit frame, and the deviation sensor and the drive motor are electrically connected to the control system. When the drive wheel reverses direction, the swing arm swings with the drive wheel, and the free end of the swing arm abuts against the limiting component, causing the trigger rod of the deviation sensor to deflect and trigger.

[0005] As a type of pendulum arrangement: The swing arm is disposed on the upper panel of the drive wheel, the limiting member is a limiting rib, the limiting rib is disposed on the side of the swing arm that rotates counterclockwise with the drive wheel, the deviation sensor is disposed above the drive wheel, and the limiting rib and the deviation sensor do not interfere with each other.

[0006] A stop plate is also provided on the other side of the swing arm. Between the limiting plate and the stop plate, the distance from the mounting end of the swing arm to the limiting plate is less than the distance from the rotating end of the swing arm to the stop plate. When the drive wheel rotates forward, the swing arm abuts against the stop plate, and the swing arm does not touch the deviation sensor. When the drive wheel rotates in reverse, the free end of the swing arm abuts against the limiting plate and triggers the deviation sensor.

[0007] The drive wheel is equipped with multiple swing arms, and each swing arm is equipped with a limit rib and abutment rib.

[0008] The rocker arm is rotatably connected to the drive wheel via a rocker arm seat.

[0009] As another arrangement of the pendulum rod: The swing arm is vertically suspended from the lower panel of the drive wheel, the deviation sensor is arranged below the drive wheel, and the trigger rod of the deviation sensor is arranged horizontally. A limit member is provided on the side of the swing arm that rotates in the opposite direction with the drive wheel.

[0010] The limiting component is further defined by a limiting post or a limiting rod.

[0011] A backstop is connected to the drive wheel axle.

[0012] Furthermore, the backstop includes a one-way running component, an anti-rotation shaft breakage protection frame, and an anti-rotation spindle. The one-way running component is provided on the axle of the drive wheel. The one-way running component includes an anti-rotation outer ring, and a limit arm is connected to the anti-rotation outer ring. The anti-rotation shaft breakage protection frame is fixedly connected to the drive device frame. The anti-rotation spindle is fixedly connected to the anti-rotation shaft breakage protection frame corresponding to the one-way running component. When the limit arm approaches the anti-rotation spindle, the two abut against each other.

[0013] Furthermore, the unidirectional running component also includes a rotating inner ring and a ratchet assembly. The ratchet assembly is provided between the rotating inner ring and the anti-rotation outer ring. The rotating inner ring cooperates with the axle of the drive wheel. Under the action of the ratchet assembly, when the rotating inner ring rotates, the rotating outer ring rotates in the same direction or does not rotate.

[0014] Furthermore, a shaft breakage protection plate is fixedly connected to the anti-rotation shaft breakage protection frame corresponding to the backstop by abutting bolts. The anti-rotation outer ring and the rotation inner ring are both located inside the shaft breakage protection plate. The shaft breakage protection plate abuts against the anti-rotation outer ring. A hanging leg is fixedly connected to the drive device frame, and the anti-rotation shaft breakage protection frame is fixedly connected to the hanging leg.

[0015] The beneficial effects of this utility model are: This invention features a swing arm and a limiting component on the drive wheel. Utilizing the rotational force of the drive wheel, when rotating forward, the swing arm is unrestricted and cannot trigger the deviation sensor. When the drive wheel rotates in reverse, the free end of the swing arm swings with the rotational force of the drive wheel, hitting the limiting component and then continuing to rotate with the drive wheel. This causes the trigger rod of the deviation sensor to deflect and trigger. The control system receives the trigger deflection signal from the deviation sensor and controls the drive motor to stop working, thereby achieving electrical anti-reverse protection against the reverse rotation of the drive wheel.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0020] Please see Figures 1 to 6 This embodiment discloses a cableway drive wheel anti-reverse device, including a drive motor 100, a drive device frame 200, a drive wheel 300, a transmission shaft 400, a backstop, and a control system. First, please refer to... Figure 1 A drive motor 100 is fixedly connected to the drive device frame 200, and a drive wheel 300 is rotatably connected to the drive device frame 200. The drive motor 100 is poweredly connected to the drive wheel 300 through a transmission shaft 400, so that the drive motor 100 can drive the drive wheel 300 to rotate.

[0021] In this embodiment, the backstop cooperates with the axle of the drive wheel 300, so that the backstop can prevent the drive wheel 300 from rotating in the opposite direction. For details, please refer to [link to relevant documentation]. Figure 1 The backstop includes a one-way running component 501, an anti-rotation and shaft breakage protection frame 502, and an anti-rotation spindle 503. Specifically, the one-way running component 501 is provided on the axle of the drive wheel 300. The one-way running component 501 includes an anti-rotation outer ring 504, and a limit arm 505 is fixedly connected to the anti-rotation outer ring 504. A hanging leg 600 is fixedly connected to the drive unit frame 200, and an anti-rotation and shaft breakage protection frame 502 is fixedly connected to the hanging leg 600. An anti-rotation and shaft breakage protection frame 502 is fixedly connected to the anti-rotation and shaft breakage protection frame 502 corresponding to the one-way running component 501. The limit arm 505 abuts against the anti-rotation and shaft breakage protection frame 503.

[0022] To elaborate further, please refer to Figure 2 The aforementioned one-way running component 501 also includes a rotating inner ring 506 and a ratchet assembly 507. That is, a ratchet assembly 507 is provided between the rotating inner ring 506 and the anti-rotation outer ring 504. The rotating inner ring 506 cooperates with the axle of the drive wheel 300. Thus, under the action of the ratchet assembly 507, when the rotating inner ring 506 rotates, the rotating outer ring rotates in the same direction or does not rotate. More specifically, in this embodiment, when the drive wheel 300 rotates in the forward direction, the rotating inner ring 506 rotates in the forward direction according to the design direction of the ratchet assembly 507. At this time, the running resistance torque of the anti-reverse device is very small, and the cableway system operates normally.

[0023] When the drive wheel 300 tends to rotate in the opposite direction, with the cooperation of the ratchet assembly 507, rotating the inner ring 506 can drive the anti-rotation outer ring 504 to rotate. At this time, because the limiting arm 505 on the anti-rotation outer ring 504 abuts against the anti-rotation spindle 503, the entire backstop can be limited to prevent the drive wheel 300 from rotating in the opposite direction.

[0024] Furthermore, please refer to Figure 2On the anti-rotation shaft breakage protection frame 502, a shaft breakage protection plate 702 is fixedly connected to the corresponding backstop via an abutment bolt 701. The anti-rotation outer ring 504 and the rotating inner ring 506 are located inside the shaft breakage protection plate 702. The abutment bolt 701 abuts against the anti-rotation outer ring 504. This structure allows the shaft breakage protection plate 702 to temporarily support the rotating parts when the backstop experiences shaft breakage, preventing them from falling off and causing a chain of failures. Furthermore, the fixing force of the abutment bolt 701 can bear the axial load on the backstop.

[0025] The mechanical backstop is installed on the axle of the drive wheel to achieve end-point anti-reverse protection. Compared with the traditional installation on the front motor or hydraulic motor, or the middle reducer or transmission component, it is safer and more reliable.

[0026] Please see Figure 3 , Figure 4 An electrical anti-reverse protection mechanism is also provided on the drive wheel 300. The electrical anti-reverse protection mechanism includes a swing arm 801, a deviation sensor 802, and a limiting component. At least one swing arm 801 is rotatably connected to the drive wheel 300. A limiting component is provided on one side of the swing arm 801. A deviation sensor 802 is provided on the drive device frame 200. The deviation sensor 802 and the drive motor 100 are electrically connected to a control system. When the drive wheel 300 reverses, it swings with the drive wheel 300. The free end of the swing arm 801 is stopped by the limiting component and drives the trigger rod of the deviation sensor 802 to deflect and trigger.

[0027] In this embodiment, a swing arm and a limiting component are installed on the drive wheel. Utilizing the rotational force of the drive wheel, when rotating forward, the swing arm is free to move and cannot trigger the deviation sensor. When the drive wheel rotates in reverse, the free end of the swing arm swings with the rotational force of the drive wheel and comes into contact with the limiting component, and continues to rotate with the drive wheel, causing the trigger rod of the deviation sensor to deflect and trigger. The control system receives the trigger deflection signal from the deviation sensor and controls the drive motor to stop working, thereby achieving electrical anti-reverse protection against the reverse rotation of the drive wheel.

[0028] As a type of 801 pendulum arrangement: A swing arm 801 is mounted on the upper panel of the drive wheel 300. A limiting rib 803 is used as a limiting member, positioned on the side of the swing arm 801 that rotates counter-clockwise with the drive wheel 300. A deviation sensor 802 is positioned above the drive wheel (300). The limiting rib 803 and the deviation sensor 802 do not interfere with each other. A retaining rib 805 is also provided on the other side of the swing arm 801. The limiting rib 803 and the retaining rib 805... Between 0 and 5, the distance from the mounting end of the swing arm 801 to the limiting rib plate 803 is less than the distance from the rotating end of the swing arm 801 to the abutting rib plate 805. When the drive wheel 300 rotates forward, the swing arm 801 abuts against the abutting rib plate 805, and the swing arm 801 does not touch the deviation sensor 802. When the drive wheel 300 rotates in reverse, the free end of the swing arm 801 abuts against the limiting rib plate 803 and triggers the deviation sensor.

[0029] In practical applications, to ensure that the control system can quickly and accurately respond to the reverse rotation failure of the drive wheel 300, multiple rocker arms 801 are provided on the drive wheel 300. Each rocker arm 801 is provided with a limiting rib 803 and an abutment rib 805. The limiting rib 803 and the abutment rib 805 are both rib strips arranged on the drive wheel 300 and have the same structure. The side closer to the mounting end of the rocker arm 801 is the limiting rib 803, and the side farther away from the mounting end of the rocker arm 801 is the abutment rib 805. When multiple rocker arms 801 are evenly arranged on the drive wheel 300, adjacent rocker arms 801 share the same rib strip. For two adjacent rocker arms 801, one rocker arm 802 uses this rib strip for reverse rotation limiting, and the other rocker arm 802 uses this rib strip for forward rotation abutment.

[0030] The rocker arm 801 is rotatably connected to the rocker arm seat 804 via a bearing. The rocker arm seat 804 is mounted on the drive wheel 300. Figures 4-5 As shown, the swing arm 801 has 6 sets. A deviation sensor 802 is fixedly connected to the drive unit frame 200. The trigger rod of the deviation sensor 802 is vertically arranged above the drive wheel 300. The limiting rib plate 803 and the abutment rib plate 805 do not interfere with the deviation sensor 802. When the drive station 300 rotates forward, the free end of the swing arm 801 abuts against the abutment rib plate 805 and does not contact the deviation sensor 802. When the drive wheel 300 rotates in reverse, the swing arm 801 abuts against the limiting member, and the trigger rod of the deviation sensor 802 connects with the swing arm 801. Under the reverse rotation of the drive wheel 300, the trigger rod of the deviation sensor 802 is driven to deviate, thereby triggering the deviation signal to the control system to drive the motor 100 to perform an emergency stop.

[0031] Please see Figure 5When the drive wheel 300 rotates clockwise (counterclockwise), the rocker arm 801 is in the right position. At this time, the length of the rocker arm 801 in the radial direction of the drive wheel 300 is short, and the rocker arm 801 will not touch the position sensor 802, so the system operates normally.

[0032] Please see Figure 6 When the drive wheel 300 reverses (clockwise), the rocker arm 801 is in the left position. At this time, the length of the rocker arm 801 in the radial direction of the drive wheel 300 is longer. When it touches the position sensor 802, the position sensor 802 transmits the signal to the control system, and the control system alarms and stops the machine, thus realizing electrical anti-reverse protection. Example

[0033] Please refer to the details. Figures 7 to 8 The difference between this embodiment and Embodiment 1 lies in the arrangement of the swing arm 801 and the deviation sensor 802, as detailed below: The swing arm 801 is vertically suspended on the lower panel of the drive wheel 300. The deviation sensor 802 is arranged below the drive wheel 300, and the trigger rod of the deviation sensor is arranged horizontally. A limit member is provided on the side of the swing arm 801 that rotates in the opposite direction with the drive wheel 300.

[0034] When the drive wheel rotates forward, the swing arm 801 is driven by the rotation of the drive wheel and is in a free swinging state without any limiting force. The swing arm 801 swings past the deviation sensor 802 without giving the deviation sensor 802 a large squeezing force, so it cannot trigger the deviation and the system operates normally.

[0035] When the drive wheel reverses, the rocker arm 801 rotates with the drive wheel and is positioned by the limiting component. The rocker arm 801 touches the deviation sensor 802 as the drive wheel rotates, and continuously applies force to the trigger rod of the deviation sensor 802, causing the trigger rod to deviate. The deviation sensor 802 sends a deviation signal, and the control system receives the deviation signal and controls the drive motor to stop working, thereby realizing the electrical anti-reverse protection against the reverse rotation of the drive wheel.

[0036] The limiting component is a limiting post or a limiting rod.
