Description

Technical Field

[0001] The present invention relates to, but is not limited to, the technical field of rapid separation of a reducer after self-locking, and in particular to a remote separation control device for use in a closed space and a method of using the same. Background Art

[0002] In common transmission motion systems, a combination of a motor and a reducer is often used for power input to the motion system, and a rack and pinion method is used for driving. However, during the motion process, the motor often becomes stalled or the reducer self-locks.

[0003] In this case, the entire motion system will be in a shutdown state and all transmission mechanisms will be unable to move. However, in some special cases, the product needs to be released through the transmission mechanism, that is, the transmission mechanism and the drive mechanism must be quickly separated in an emergency. However, in some compact spaces or emergency situations, standard tools cannot be used to unlock the above two mechanisms, and thus the product cannot be released. Summary of the Invention

[0004] Purpose of the present invention: In order to solve the above technical problems, an embodiment of the present invention provides a remote separation control device for a closed space and a method of use thereof, so as to solve the problem that when the transmission system is in the case of motor stall or reducer self-locking, the transmission mechanism cannot be quickly separated, resulting in the inability to release the product.

[0005] Technical solution of the present invention: In a first aspect, an embodiment of the present invention provides a remote separation control device for use in a closed space, comprising: a mounting base 1, two sets of linear guide rails 2, two sliding plates 3, two rack mounting plates 4, a motor base 6, a driving mechanism 13, and a separation mechanism;

[0006] Among them, a positioning step is symmetrically provided on both sides of the mounting base 1 for correspondingly installing two sets of linear guide rails 2; a sliding plate 3 and a rack mounting plate 4 are respectively installed on each linear guide rail 2 through a slider, and the sliding plates 3 and rack mounting plates 4 on the two linear guide rails 2 are installed in a diagonal form; a rack 5 is installed on the inner upper end surface of each rack mounting plate 4, and each rack 5 extends to the outer end of the sliding plate 3 on the same side;

[0007] The motor base 6 is fixedly mounted in the middle of the mounting base 1 and is located between the two racks 5. A driving mechanism 13 is fixedly mounted on the upper end of the motor base 6. A separation mechanism is installed inside the motor base 6. The bottom disk of the driving shaft 12 of the driving mechanism is connected to the floating end plate 10 provided on the top of the separation mechanism through a quick-release pin. The floating end plate 10 is mounted above the gear 9 at a preset distance, and the floating end plate 10 is connected to the upper end surface of the gear 9 through a connecting pin. The gear 9 of the separation mechanism is respectively engaged with the racks 5 on both sides;

[0008] The bottom end of the floating control rod 17 that passes through the floating end plate 10 from the top downward is connected to the control rope 16. The floating control rod 17 is pulled downward by the control rope 16 to drive the floating end plate 10 to separate from the driving shaft 12 of the driving mechanism, thereby realizing the separation of the separation mechanism from the driving mechanism 13.

[0009] Optionally, in the remote separation control device for use in a closed space as described above, the separation mechanism includes: a bearing 7, a rotating seat 8, a gear 9, a floating end plate 10, an annular magnet 11, and a floating control rod 17;

[0010] Among them, the bearing 7 is fixedly mounted on the lower base plate of the motor base 6, the rotating base 8 is fixedly mounted on the inner ring of the bearing 7, the gear 9 is press-fitted into the rotating base 8, and the floating end plate 10 mounted above the gear 9 is connected to the upper end surface of the gear 9 through a connecting pin; the shaft body of the drive shaft 12 passes through the upper end plate from the bottom of the upper end plate of the motor base 6 and is fixedly connected to the inside of the drive mechanism 13. The disc body of the drive shaft 12 located in the motor base 6 is connected to the floating end plate 10 through a quick-release pin, so that the drive shaft 12, the floating end plate 10 and the gear 9 form a linkage structure;

[0011] A step through hole is opened in the middle of the floating end plate 10, and a ring magnet 11 is pressed on the step end surface of the step through hole; a floating control rod 17 with a limiting end at the top passes through the step through hole of the floating end plate 10, the ring magnet 11 and the center of the gear 9 with its rod body, and a control rope 16 is connected to the bottom end of the rod body. Under the action of the mutual repulsive force of the ring magnet 11, the floating control rod 17 is pushed upward, and the floating end plate 10 is kept at a preset distance from the gear 9 to maintain the linkage structure between the drive shaft 12, the floating end plate 10 and the gear 9.

[0012] Optionally, in the remote separation control device for use in a closed space as described above,

[0013] The driving mechanism 13 drives the driving shaft 12 to rotate axially, and the driving shaft 12 drives the floating end plate 10 to rotate axially, and drives the gear 9 to rotate axially through the floating end plate 10, and the gear 9 transmits the rotation to the racks 5 on both sides, so that the rack mounting plates 4 on both sides move in opposite directions, thereby achieving clamping and releasing of the product.

[0014] When the drive mechanism 13 fails or is blocked, the control rope 16 is tightened, and the control rope 16 passes over the pulley block 15 to drag the floating control rod 17, causing the floating control rod 17 to move axially downward. The floating control rod 17 drives the floating end plate 10 downward to the upper end surface of the gear 9, and separates the floating end plate 10 from the disk body of the drive shaft 12, that is, the gear 9 is separated from the drive mechanism 13, and the gear 9 and the rack 5 have the ability to move independently;

[0015] When the driving mechanism 13 operates normally, the control rope 16 is released. When the control rope 16 is in a free state, the floating control rod 17 rebounds upward under the mutual repulsive force of the magnet 11, and the floating end plate 10 automatically returns to its position by gently pushing the rack 5, thereby restoring the linkage between the floating end plate 10 and the driving shaft 12.

[0016] Optionally, in the remote separation control device for use in a closed space as described above, the separation mechanism further comprises: an anti-rotation mechanism 14;

[0017] The threaded end of the lower end of the anti-rotation mechanism 14 is fixedly installed in the threaded hole of the mounting base 1, and the upper end is sleeved on the lower end of the floating control rod 17 and the part of the control rope 16 located on the mounting seat 6, which is used to prevent the floating control rod 17 and the control rope 16 from twisting during movement.

[0018] Optionally, in the remote separation control device for use in a closed space as described above, the anti-rotation mechanism 14 comprises: a fixed anti-rotation seat 18 and a clamping shaft 19;

[0019] The lower sleeve of the fixed anti-rotation seat 18 is screwed into the threaded hole in the middle of the mounting base 1, and the upper sleeve is sleeved on the lower end of the floating control rod 17, and forms an interference fit installation form with the floating control rod 17; the inner wall of the upper sleeve of the fixed anti-rotation seat 18 forms axial grooves symmetrically arranged on both sides, and the clamping shaft 19 passes through the through hole at the lower end of the rod body of the floating control rod 17, and the two ends are correspondingly arranged in the axial grooves on both sides. The clamping shaft 19 moves up and down along the axial grooves on both sides to radially position the up and down movement of the floating control rod 17, thereby realizing the anti-rotation effect on the floating control rod 17.

[0020] Optionally, in the above-mentioned remote separation control device for use in a closed space, the separation mechanism further comprises: a pulley assembly 15;

[0021] The pulley block 15 is fixedly mounted on the bottom of the lower end surface of the mounting base 1 and is located below the floating control rod 17. One end of the control rope 16 is locked and connected to the bottom end of the floating control rod 17, and the other end passes around the pulley block 15 and is pulled to the operating end.

[0022] Optionally, in the remote separation control device for use in a closed space as described above, the pulley assembly 15 includes: a pulley 20, a wheel frame 21, two shaft sleeves 22, a pulley shaft 23, a retaining ring 24 for an elastic shaft, and two bearings 25;

[0023] The pulley 20 is configured as a disk structure with a V-shaped groove or a U-shaped groove in the center. The wheel frame 21 is fixedly mounted on the lower end surface of the mounting base 1 through its base. An elastic shaft retaining ring 24 is provided on the outer side of the ear on one side of the wheel frame 21.

[0024] Two bearings 25 are correspondingly mounted on both ends of the shaft hole of the pulley 20, and a sleeve 22 is provided inside each bearing 25 for the inner ring of the bearing. After the pulley shaft 23 passes through the shaft hole of the pulley 20 and the two sleeves 22, one end passes through one side ear and is clamped on the elastic shaft retaining ring 24, and the other end rests on the other side ear of the wheel frame 21.

[0025] Optionally, in the remote separation control device for use in a closed space as described above,

[0026] The limit end at the top of the floating control rod 17 and the magnet 11 repel each other in the absence of external force, so that the floating control rod 17 remains in a floating state, and the floating control rod 17 drives the clamping shaft 19 to move up to the top of the fixed anti-rotation seat 18;

[0027] When a downward force is applied to the floating control rod 17 through the control rope 16, the tension on the floating control rod 17 is greater than the repulsive force between it and the magnet 11, causing the floating control rod 17 to move downward and drive the clamping shaft 19 to move to the bottom of the fixed anti-rotation seat 18, thereby separating the floating end plate 10 and the drive shaft 12, that is, separating the separation mechanism 13 and the drive mechanism 13, so that the separation mechanism 13 and the rack 9 do not follow the movement of the drive mechanism 13.

[0028] In a second aspect, an embodiment of the present invention further provides a method for using a remote separation control device for use in a closed space. The method for using a remote separation control device for use in a closed space, as described in any of the above, includes: when the drive mechanism 13 is stuck, separating the drive mechanism 13 and the separation mechanism to release the clamped product. The method includes:

[0029] Step 1: After the driving mechanism 13 is locked or self-locked, the driving shaft 12 cannot rotate, so that the rotating base 8 cannot move relative to it;

[0030] Step 2: Drag the control rope 16 along the groove direction of the pulley 20 in the pulley block 15, so that the rotating seat 8 moves downward and separates from the drive shaft 12, so that the gear 9 and the rack 8 can move freely;

[0031] Step 3: The fixed anti-rotation seat 18 in the anti-rotation mechanism 14 prevents the control rope 16 from rotating relative to each other during the relative movement between the gear 9 and the rack 8;

[0032] Step 4: After the stall is canceled, loosen the wire rope 16 and gently rotate the rotating seat 8 so that the diagonal hole of the rotating seat 8 falls into the pin on the drive shaft 12 during the rotation process;

[0033] In step 5, the rotating seat 8 is connected to the driving shaft 12, and the mechanism resumes normal operation.

[0034] Beneficial effects of the present invention: The embodiment of the present invention provides a remote separation control device for use in a closed space and a method for using the same. The method of separating the drivable shaft 12 and the gear 9 by the rotating seat 8 is used to rotate the transmission system independently of the drive mechanism 13. The separability of the structure of the driving end itself is used to achieve rapid separation of the mechanism in the case of self-locking or stalling. The adjustability and adaptability between the various hole positions between the rotating seat 8, the gear 9, and the drive shaft 12 mounting seat are used to achieve centering between the various hole positions, which not only meets the rapid recovery of the mechanism, but also meets the timely release of the gear and the drive assembly in an instant. The anti-rotation mechanism 14 and the steel wire rope 16 are connected to realize the remote controllability of the device and ensure the safety and service life of the device. The relative position relationship between the pulley block 15 and the steel wire rope 16 is adjusted to ensure the smoothness and accuracy of the device during the disengagement process, which not only satisfies the timeliness of the instantaneous release of the gears and the drive components, but also satisfies the instantaneous detachability of the mechanism. The structure is simple, stable and reliable, easy to operate and convenient to control, which greatly ensures the reliability of the equipment in the event of an emergency during operation.

[0042] To make the purpose, technical solutions and advantages of the present invention more clearly understood, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other in any manner.

[0043] As described in the above background technology, when the motor of the transmission system is stalled or the reducer is self-locked, the transmission mechanism cannot be quickly separated, resulting in the problem of being unable to release the product.

[0044] To address the current problem of transmission systems being able to quickly disengage in the event of a motor stall or a self-locking reducer, there is an urgent need to develop a simple, stable, reliable, easy-to-operate, and conveniently controlled integrated anti-self-locking quick disconnect in order to improve work efficiency and ensure product quality. To address this need, embodiments of the present invention provide a remote disconnect control device for use in enclosed spaces and its method of use, which can be used in various devices requiring rapid disconnection in the event of a self-locking condition.

[0045] The present invention provides the following specific embodiments that can be combined with each other. The same or similar concepts or processes may not be described in detail in some embodiments.

[0046] Figure 1 A schematic diagram of the overall structure of a remote separation control device for use in a closed space provided by an embodiment of the present invention; Figure 2 for Figure 1 A cross-sectional view along AA of the distal separation control device for use in a closed space is shown; Figure 3 for Figure 1 A cross-sectional view along BB of the distal separation control device for use in a closed space is shown.

[0047] See also Figures 1 to 3 As shown, the remote separation control device for a closed space provided by an embodiment of the present invention has a structure including: a mounting base 1, two sets of linear guide rails 2, two sliding plates 3, two rack mounting plates 4, a motor base 6, a driving mechanism 13 and a separation mechanism.

[0048] like Figures 1 to 3In the remote separation control device shown, a positioning step is symmetrically provided on both sides of the mounting base 1 for correspondingly installing two sets of linear guide rails 2; a sliding plate 3 and a rack mounting plate 4 are respectively installed on each linear guide rail 2 through a slider, and the sliding plates 3 and rack mounting plates 4 on the two linear guide rails 2 are installed in a diagonal form; a rack 5 is installed on the inner upper end surface of each rack mounting plate 4, and each rack 5 extends to the outer end of the sliding plate 3 on the same side.

[0049] The motor base 6 is fixedly mounted in the middle of the mounting base 1 and is located between the two racks 5. A driving mechanism 13 is fixedly mounted on the upper end of the motor base 6. A separation mechanism is installed inside the motor base 6. The bottom disk of the driving shaft 12 of the driving mechanism is connected to the floating end plate 10 provided on the top of the separation mechanism through a quick-release pin. The floating end plate 10 is mounted above the gear 9 at a preset distance, and the floating end plate 10 is connected to the upper end face of the gear 9 through a connecting pin. The gear 9 of the separation mechanism is respectively engaged with the racks 5 on both sides.

[0050] The bottom end of the floating control rod 17 that passes through the floating end plate 10 from the top downward is connected to the control rope 16. The floating control rod 17 is pulled downward by the control rope 16 to drive the floating end plate 10 to separate from the driving shaft 12 of the driving mechanism, thereby realizing the separation of the separation mechanism from the driving mechanism 13.

[0051] It should be noted that in the distal separation control device provided by the present invention, the control rope 16 serves as a distal control component, which applies a force at the distal end through its connection with the floating control rod 17 to control the up and down movement of the floating end plate 10 through the floating control rod 17.

[0052] The working form of the remote separation control device provided by the embodiment of the present invention under normal working conditions is: the floating end plate 10 and the gear 9 of the separation mechanism are driven to rotate synchronously through the driving mechanism 13, the racks 5 on both sides are driven to move synchronously in opposite directions, and the rack mounting plates 4 on both sides are driven to move in opposite directions, or to move away in opposite directions, thereby achieving clamping or release of the product.

[0053] In one implementation of the embodiment of the present invention, Figure 2 and Figure 3 As shown, the separation mechanism includes: a bearing 7, a rotating seat 8, a gear 9, a floating end plate 10, an annular magnet 11, and a floating control rod 17.

[0054] In this implementation, the bearing 7 is fixedly mounted on the lower base plate of the motor base 6, the rotating base 8 is fixedly mounted on the inner ring of the bearing 7, the gear 9 is pressed into the rotating base 8, and the floating end plate 10 mounted above the gear 9 is connected to the upper end face of the gear 9 through a connecting pin; the shaft body of the drive shaft 12 passes through the upper end plate from the bottom of the upper end plate of the motor base 6 and is fixedly connected to the inside of the drive mechanism 13. The disk body of the drive shaft 12 located in the motor base 6 is connected to the floating end plate 10 through a quick-release pin, so that the drive shaft 12, the floating end plate 10 and the gear 9 form a linkage structure.

[0055] In an optional implementation, the two diagonal corners of the floating end plate 10 are connected to the upper end surface of the gear 9 using connecting pins, and the two diagonal corners of the floating end plate 10 are connected to the bottom disk of the drive shaft 12 using quick-release pins.

[0056] In this implementation, a step through hole is opened in the middle of the floating end plate 10, and a ring magnet 11 is pressed on the step end surface of the step through hole; after the floating control rod 17 with a limiting end at the top passes through the step through hole of the floating end plate 10, the ring magnet 11 and the center of the gear 9 with its rod body, a control rope 16 is connected to the bottom end of the rod body. Under the action of the mutual repulsive force of the ring magnet 11, the floating control rod 17 is pushed upward, and the floating end plate 10 is kept at a preset distance from the gear 9 to maintain the linkage structure between the drive shaft 12, the floating end plate 10 and the gear 9.

[0057] The above-mentioned remote separation control device for a closed space provided by an embodiment of the present invention is driven by a driving mechanism 13 to drive the driving shaft 12 to rotate axially, and the driving shaft 12 drives the floating end plate 10 to rotate axially, and the floating end plate 10 drives the gear 9 to rotate axially, and the gear 9 transmits the rotation to the racks 5 on both sides, so that the rack mounting plates 4 on both sides move in opposite directions, thereby achieving clamping and release of the product.

[0058] When the drive mechanism 13 fails or is blocked, the control rope 16 is tightened, and the control rope 16 passes over the pulley block 15 to drag the floating control rod 17, causing the floating control rod 17 to move axially downward. The floating control rod 17 drives the floating end plate 10 downward to the upper end surface of the gear 9, and separates the floating end plate 10 from the disk body of the drive shaft 12, that is, the gear 9 is separated from the drive mechanism 13, and the gear 9 and the rack 5 have the ability to move independently;

[0059] When the driving mechanism 13 operates normally, the control rope 16 is released. When the control rope 16 is in a free state, the floating control rod 17 rebounds upward under the mutual repulsive force of the magnet 11, and the floating end plate 10 automatically returns to its position by gently pushing the rack 5, thereby restoring the linkage between the floating end plate 10 and the driving shaft 12.

[0060] In one implementation of the embodiment of the present invention, Figure 2 and Figure 3As shown, the separation mechanism may further include an anti-rotation mechanism 14 .

[0061] In this implementation, the threaded end of the lower end of the anti-rotation mechanism 14 is fixedly installed in the threaded hole of the mounting base 1, and the upper end is sleeved on the lower end of the floating control rod 17 and the part of the control rope 16 located on the mounting seat 6, which is used to prevent the floating control rod 17 and the control rope 16 from twisting during movement.

[0062] In a specific implementation, the anti-rotation mechanism 14 includes a fixed anti-rotation seat 18 and a clamping shaft 19 .

[0063] like Figure 3 As shown, the lower sleeve of the fixed anti-rotation seat 18 is screwed into the threaded hole in the middle of the mounting base 1, and the upper sleeve is sleeved on the lower end of the floating control rod 17, and forms an interference fit installation form with the floating control rod 17; the inner wall of the upper sleeve of the fixed anti-rotation seat 18 forms axial grooves symmetrically arranged on both sides, and the clamping shaft 19 passes through the through hole at the lower end of the rod body of the floating control rod 17, and the two ends are correspondingly arranged in the axial grooves on both sides. The clamping shaft 19 moves up and down along the axial grooves on both sides to radially position the up and down movement of the floating control rod 17, thereby realizing the anti-rotation effect on the floating control rod 17.

[0064] In one implementation of the embodiment of the present invention, Figure 3 As shown, the separation mechanism may further include: a pulley set 15.

[0065] In this implementation, the pulley group 15 is fixedly installed at the bottom of the lower end surface of the mounting base 1 and is located below the floating control rod 17. One end of the control rope 16 is locked and connected to the bottom end of the floating control rod 17, and the other end passes around the pulley group 15 and is pulled to the operating end.

[0066] In a specific embodiment, Figure 4 As shown, the pulley assembly 15 includes: a pulley 20, a wheel frame 21, two shaft sleeves 22, a pulley shaft 23, a retaining ring 24 for an elastic shaft, and two bearings 25.

[0067] The pulley 20 is configured as a disk structure with a V-shaped groove or a U-shaped groove in the center. The wheel frame 21 is fixedly mounted on the lower end surface of the mounting base 1 through its base. An elastic shaft retaining ring 24 is provided on the outer side of the ear on one side of the wheel frame 21.

[0068] Two bearings 25 are correspondingly mounted on both ends of the shaft hole of the pulley 20, and a sleeve 22 is provided inside each bearing 25 for the inner ring of the bearing. After the pulley shaft 23 passes through the shaft hole of the pulley 20 and the two sleeves 22, one end passes through one side ear and is clamped on the elastic shaft retaining ring 24, and the other end rests on the other side ear of the wheel frame 21.

[0069] In an optional embodiment of the present invention, the rotating seat 8 is a stepped hollow cylindrical thin-walled structure, the top large-diameter end forms a tight fit structure with the lower end of the gear, the bottom small-diameter end forms a tight fit structure with the inner ring of the bearing 7, the step on the outer cylindrical surface is in contact with the upper end face of the inner ring of the bearing 7, and a groove is provided on the outer cylindrical surface of the small-diameter end, and a locking gasket is provided in the groove. The axial movement of the rotating seat 8 is limited by the step and the locking gasket.

[0070] In an optional embodiment of the present invention, the drive shaft 12 is configured as an axial part having a disc body at one end, and the shaft body is connected to the drive mechanism 13 by a key. A pin hole is opened diagonally at the other end of the disc body, and a blind hole is opened in the middle of the bottom end of the disc body. The top of the floating control rod 17 is located in the blind hole.

[0071] In an optional embodiment of the present invention, the floating end plate 10 is a disc structure, and a through elongated groove is provided in the middle of the upper end surface of the floating end plate 10. The width of the elongated groove is set corresponding to the pin hole on the drive shaft 12 and the width of the elongated groove is slightly larger than the diameter of the pin hole. A stepped through hole is opened in the center of the floating end plate 10, and the magnet 11 is pressed onto the stepped end surface of the stepped through hole. After the floating control rod 17 passes through the stepped through hole, the top limit end is located above the magnet 11, and forms a repulsive force on it through the magnet 11.

[0072] In addition, the pulley block 15 through which the control rope 16 passes is wound between the pulley grooves. By controlling the tension of the control rope 16 at the far end, the separation movement form of the driving mechanism 13 and the separation mechanism is controlled.

[0073] The remote control method of the remote separation control device for a closed space provided by the above embodiment of the present invention is:

[0074] The limit end at the top of the floating control rod 17 and the magnet 11 repel each other in the absence of external force, so that the floating control rod 17 remains in a floating state, and the floating control rod 17 drives the clamping shaft 19 to move up to the top of the fixed anti-rotation seat 18;

[0075] When a downward force is applied to the floating control rod 17 through the control rope 16, the tension on the floating control rod 17 is greater than the repulsive force between it and the magnet 11, causing the floating control rod 17 to move downward and drive the clamping shaft 19 to move to the bottom of the fixed anti-rotation seat 18, thereby separating the floating end plate 10 and the drive shaft 12, that is, separating the separation mechanism 13 and the drive mechanism 13, so that the separation mechanism 13 and the rack 9 do not follow the movement of the drive mechanism 13.

[0076] Based on the remote separation control device for use in a closed space provided by the above embodiment of the present invention, the embodiment of the present invention also provides a method for using the remote separation control device for use in a closed space, specifically: a method for separating the driving mechanism 13 and the separation mechanism when the driving mechanism 13 is stuck, so as to release the clamped product, the method comprising:

[0077] Step 1: After the driving mechanism 13 is locked or self-locked, the driving shaft 12 cannot rotate, so that the rotating base 8 cannot move relative to it;

[0078] Step 2: Drag the control rope 16 along the groove direction of the pulley 20 in the pulley block 15, so that the rotating seat 8 moves downward and separates from the drive shaft 12, so that the gear 9 and the rack 8 can move freely;

[0079] Step 3: The fixed anti-rotation seat 18 in the anti-rotation mechanism 14 prevents the control rope 16 from rotating relative to each other during the relative movement between the gear 9 and the rack 8;

[0080] Step 4: After the stall is canceled, loosen the wire rope 16 and gently rotate the rotating seat 8 so that the diagonal hole of the rotating seat 8 falls into the pin on the drive shaft 12 during the rotation process;

[0081] In step 5, the rotating seat 8 is connected to the driving shaft 12, and the mechanism resumes normal operation.

[0082] By implementing steps 1 to 5, after the drivable shaft 12 and the gear 8 are separated by the rotating seat 8, the movement of the gear 9 and the rack 8 is independent of the driving mechanism 13 and is rotated independently, and is not subject to the stalling or self-locking of the driving mechanism 13, so as to release the product.

[0083] The embodiment of the present invention provides a remote separation control device for use in a closed space and a method for using the same. The method adopts a rotating seat 8 to separate the drivable shaft 12 and the gear 9, so that the transmission system rotates independently of the drive mechanism 13. The separability of the structure of the driving end itself can realize the rapid separation of the mechanism in the case of self-locking or stalling. The adjustability and adaptability between the various holes between the rotating seat 8, the gear 9, and the drive shaft 12 mounting seat are utilized to achieve the centering between the various holes, which not only meets the rapid recovery of the mechanism, but also meets the timeliness of the instantaneous release of the gear and the drive assembly. It also meets the instantaneous detachability of the mechanism. Through the connection between the anti-rotation mechanism 14 and the wire rope 16, the remote controllability of the device is achieved and the safety and service life of the device are guaranteed. By adjusting the relative position relationship between the pulley group 15 and the wire rope 16, the smoothness and accuracy of the device during the disengagement movement are ensured, which not only meets the timeliness of the instantaneous release of the gears and drive components, but also meets the instantaneous detachability of the mechanism. It has a simple structure, is stable and reliable, easy to operate, and convenient to control, which greatly guarantees the reliability of the equipment in the event of emergencies during operation.
