Abstract

This invention discloses a remote separation control device and its usage method for use in enclosed spaces. In the control device, a positioning step is symmetrically arranged on both sides of a mounting base plate for mounting two sets of linear guides. Each linear guide rail has a sliding plate and a rack mounting plate mounted on it via a slider, with the sliding plate and rack mounting plate on the two linear guide rails installed diagonally. A rack is mounted on the upper inner surface of each rack mounting plate, and each rack extends to the outer end of the sliding plate on the same side. A motor mount is fixedly installed in the middle of the mounting base plate, located between the two racks. A drive mechanism is fixedly installed on the upper end of the base. A separation mechanism is installed inside the motor base. The bottom disc of the drive shaft of the drive mechanism is connected to a floating end plate on the top of the separation mechanism via a quick-release pin. The floating end plate is positioned above the gear at a preset distance and is connected to the upper surface of the gear via a connecting pin. The gears of the separation mechanism mesh with racks on both sides. A control rope is connected to the bottom end of a floating control rod that runs downwards through the floating end plate. Pulling the floating control rod downwards via the control rope causes the floating end plate to separate from the drive shaft of the drive mechanism, thus separating the separation mechanism from the drive mechanism. The technical solution provided by this invention solves the problem that the product cannot be released when the transmission mechanism cannot quickly separate in the case of motor stall or reducer self-locking.

Description

Technical Field

[0001] This invention relates to, but is not limited to, the field of rapid separation technology after a speed reducer self-locks, and particularly to a remote separation control device and its usage method for use in enclosed spaces. Background Technology

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

[0003] In this situation, the entire motion system will be at a standstill, and all transmission mechanisms will be unable to move. However, in some special cases, it is necessary to release the product through the transmission mechanism, which requires the rapid separation of the transmission mechanism and the drive mechanism in an emergency. In some compact spaces or in emergency situations, it is not possible to unlock the two mechanisms using standard tools, thus making it impossible to release the product. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned technical problems. This invention provides a remote separation control device and its usage method for use in enclosed spaces, in order to solve the problem that the product cannot be released when the transmission mechanism cannot be quickly separated due to motor stall or reducer self-locking.

[0005] The technical solution of the present invention: In a first aspect, the embodiments of the present invention provide a remote separation control device for a closed space, comprising: a mounting base plate 1, two sets of linear guide rails 2, two sliding plates 3, two rack mounting plates 4, a motor base 6, a drive mechanism 13, and a separation mechanism;

[0006] The mounting base plate 1 has a positioning step symmetrically arranged on both sides for mounting two sets of linear guide rails 2. Each linear guide rail 2 is mounted with a sliding plate 3 and a rack mounting plate 4 via a slider, and the sliding plate 3 and rack mounting plate 4 on the two linear guide rails 2 are installed diagonally. A rack 5 is installed on the upper inner 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 installed in the middle of the mounting base plate 1 and located between the two racks 5. The upper end of the motor base 6 is fixedly installed with a drive mechanism 13. The motor base 6 is installed with a separation mechanism. The bottom plate of the drive shaft 12 of the drive mechanism is connected to the floating end plate 10 set 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 is connected to the upper end face of the gear 9 through a connecting pin. The gear 9 of the separation mechanism meshes with the racks 5 on both sides respectively.

[0008] The bottom end of the floating control rod 17, which runs from the top down through the floating end plate 10, is connected to a control rope 16. By pulling the floating control rod 17 downward through the control rope 16, the floating end plate 10 is separated from the drive shaft 12 of the drive mechanism, thereby separating the separation mechanism from the drive mechanism 13.

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

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

[0011] The floating end plate 10 has a stepped through hole in the middle, and an annular magnet 11 is pressed onto the stepped end face of the stepped through hole. The floating control rod 17 with a limiting end at the top passes through the stepped through hole of the floating end plate 10, the annular magnet 11 and the center of the gear 9. The bottom end of the rod is connected to a control rope 16. Under the action of the repulsive force of the annular magnet 11, the floating control rod 17 is pushed upward, and the floating end plate 10 and the gear 9 maintain a preset distance 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 enclosed spaces as described above,

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

[0014] When the drive mechanism 13 malfunctions or stalls, the control rope 16 is tightened. The control rope 16 passes around the pulley block 15 and drags the floating control rod 17, causing the floating control rod 17 to move downward along the axial direction. The floating control rod 17 drives the floating end plate 10 to move downward to the upper end face of the gear 9, and causes the floating end plate 10 to separate from the disc of the drive shaft 12, so that the gear 9 is separated from the drive mechanism 13, and the gear 9 and rack 5 have the ability to move independently.

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

[0016] Optionally, in the remote separation control device for enclosed spaces as described above, the separation mechanism further includes: 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 plate 1, and the upper end is sleeved on the part of the lower end of the floating control rod 17 and the control rope 16 located in the mounting seat 6, which is used to prevent the floating control rod 17 and the control rope 16 from twisting during the movement.

[0018] Optionally, in the remote separation control device for an enclosed space as described above, the anti-rotation mechanism 14 includes: a fixed anti-rotation seat 18 and a retaining 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 fitted onto the lower end of the floating control rod 17, forming an interference fit with the floating control rod 17. The inner wall of the upper sleeve of the fixed anti-rotation seat 18 forms symmetrically arranged axial grooves on both sides. The retaining shaft 19 passes through the through hole at the lower end of the floating control rod 17, and its two ends are correspondingly arranged in the axial grooves on both sides. The retaining 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 achieving the anti-rotation function of the floating control rod 17.

[0020] Optionally, in the remote separation control device for an enclosed space as described above, the separation mechanism further includes: a pulley block 15;

[0021] The pulley block 15 is fixedly installed at the bottom of the lower end face of the mounting base plate 1 and located below the floating control rod 17. One end of the control rope 16 is locked to the bottom end of the floating control rod 17, and the other end is pulled to the operating end after passing around the pulley block 15.

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

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

[0024] Two bearings 25 are fitted at both ends of the shaft hole of the pulley 20, and each bearing 25 is fitted with a bushing 22 for the inner ring of the bearing. After the pulley shaft 23 passes through the shaft hole of the pulley 20 and the two bushings 22, one end passes through the side lug and is locked on the retaining ring 24 for the elastic shaft, and the other end abuts against the other side lug of the wheel frame 21.

[0025] Optionally, in the remote separation control device for enclosed spaces as described above,

[0026] The limiting end at the top of the floating control rod 17 and the magnet 11 repel each other without external force, so that the floating control rod 17 remains floating. The floating control rod 17 drives the locking 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 via 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 locking shaft 19 to the bottom of the fixed anti-rotation seat 18, thereby separating the floating end plate 10 from the drive shaft 12, that is, separating the separation mechanism 13 from the drive mechanism 13, so that neither the separation mechanism 13 nor the rack 9 follows the movement of the drive mechanism 13.

[0028] Secondly, embodiments of the present invention also provide a method of using a remote separation control device in an enclosed space, as described in any of the above-mentioned methods, comprising: separating the drive mechanism 13 and the separation mechanism when the drive mechanism 13 is jammed, in order to release the clamped product, the method of use comprising:

[0029] Step 1: After the drive mechanism 13 stalls or self-locks, the drive shaft 12 cannot rotate, so the rotating seat 8 cannot move relative to the drive mechanism 13.

[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 are in a free state of movement.

[0031] Step 3, the fixed anti-rotation seat 18 in the anti-rotation mechanism 14 ensures that the control rope 16 does not rotate relative to the gear 9 and the rack 8 during relative motion;

[0032] Step 4: After the stall is released, loosen the wire rope 16 and gently rotate the rotating seat 8 so that the diagonal holes of the rotating seat 8 fall into the pins on the drive shaft 12 during the rotation process.

[0033] Step 5: The rotating seat 8 is connected to the drive shaft 12, and the mechanism resumes normal operation.

[0034] The beneficial effects of this invention: This embodiment of the invention provides a remote separation control device and its usage method for use in enclosed spaces. It employs a method of separating the drive shaft 12 and gear 9 using a rotating seat 8, allowing the transmission system to rotate independently of the drive mechanism 13. The separability of the drive end structure enables rapid separation of the mechanism under self-locking or stall conditions. Utilizing the adjustability and adaptability of the holes between the rotating seat 8, gear 9, and drive shaft 12 mounting base, alignment between the holes is achieved, satisfying both the rapid retraction of the mechanism and the timely release of the gear and drive assembly instantaneously. It achieves both stability and instantaneous separability of the mechanism. The connection between the anti-rotation mechanism 14 and the wire rope 16 enables remote controllability of the device and ensures its safety and service life. By adjusting the relative positional relationship between the pulley block 15 and the wire rope 16, the smoothness and accuracy of the device during disengagement are ensured. It satisfies both the timeliness of the gear and drive components to be released instantaneously and the instantaneous separability of the mechanism. Its structure is simple, stable and reliable, easy to operate and convenient to control, which greatly ensures the reliability of the equipment in case of emergencies during operation.

[0042] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0043] As explained in the background section above, when the motor is stalled or the reducer is self-locked, the transmission mechanism cannot quickly disengage, resulting in the inability to release the product.

[0044] To address the current limitation of transmission systems in achieving rapid separation under motor stall or reducer self-locking conditions, and to improve work efficiency and ensure product quality, there is an urgent need to research a simple, stable, reliable, easy-to-operate, and conveniently controlled anti-self-locking integrated rapid separator. Based on this requirement, this invention provides a remote separation control device and its usage method for use in enclosed spaces, applicable to various devices requiring rapid separation under self-locking conditions.

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

[0046] Figure 1 This is a schematic diagram of the overall structure of a remote separation control device for use in an enclosed space, provided by an embodiment of the present invention. Figure 2 for Figure 1 The diagram shows a cross-sectional view along AA of a remote separation control device used in an enclosed space. Figure 3 for Figure 1 The diagram shows a cross-sectional view along BB of a remote separation control device used in an enclosed space.

[0047] See Figures 1 to 3 As shown, the remote separation control device for enclosed spaces provided in this embodiment of the invention includes: a mounting base plate 1, two sets of linear guide rails 2, two sliding plates 3, two rack mounting plates 4, a motor base 6, a drive mechanism 13, and a separation mechanism.

[0048] like Figures 1 to 3In the remote separation control device shown, a positioning step is symmetrically arranged on both sides of the mounting base plate 1 for corresponding installation of 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 by a slider, and the sliding plate 3 and rack mounting plate 4 on the two linear guide rails 2 are installed diagonally; a rack 5 is installed on the inner upper 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 installed in the middle of the mounting base plate 1 and located between the two racks 5. The upper end of the motor base 6 is fixedly installed with a drive mechanism 13. The motor base 6 is equipped with a separation mechanism. The bottom plate of the drive shaft 12 of the drive mechanism is connected to the floating end plate 10 set 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 is connected to the upper end face of the gear 9 through a connecting pin. The gear 9 of the separation mechanism meshes with the racks 5 on both sides respectively.

[0050] The bottom end of the floating control rod 17, which runs from the top down through the floating end plate 10, is connected to a control rope 16. By pulling the floating control rod 17 downward through the control rope 16, the floating end plate 10 is separated from the drive shaft 12 of the drive mechanism, thereby separating the separation mechanism from the drive mechanism 13.

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

[0052] The remote separation control device provided in this embodiment of the invention operates as follows under normal working conditions: the driving mechanism 13 drives the floating end plate 10 and gear 9 of the separation mechanism to rotate synchronously, drives the racks 5 on both sides to move synchronously in opposite directions, and drives the rack mounting plates 4 on both sides to move closer to each other in opposite directions, or to move away from each other in opposite directions, thereby achieving the clamping or release of the product.

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

[0054] In this implementation, the bearing 7 is fixedly installed on the lower base plate of the motor base 6, the rotating seat 8 is fixedly installed on the inner ring of the bearing 7, the gear 9 is press-fitted into the rotating seat 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 of the drive shaft 12 passes through 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 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 the optional implementation, the two opposite corners of the floating end plate 10 are connected to the upper end face of the gear 9 by connecting pins, and the two opposite corners of the floating end plate 10 are connected to the bottom plate of the drive shaft 12 by quick-release pins.

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

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

[0058] When the drive mechanism 13 malfunctions or stalls, the control rope 16 is tightened. The control rope 16 passes around the pulley block 15 and drags the floating control rod 17, causing the floating control rod 17 to move downward along the axial direction. The floating control rod 17 drives the floating end plate 10 to move downward to the upper end face of the gear 9, and causes the floating end plate 10 to separate from the disc of the drive shaft 12, so that the gear 9 is separated from the drive mechanism 13, and the gear 9 and rack 5 have the ability to move independently.

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

[0060] In one implementation of this invention, such as Figure 2 and Figure 3As shown, the separation mechanism may also 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 plate 1, and the upper end is sleeved on the part of the lower end of the floating control rod 17 and the control rope 16 located in the mounting seat 6, which is used to prevent the floating control rod 17 and the control rope 16 from twisting during the movement.

[0062] In specific implementation, the anti-rotation mechanism 14 includes: a fixed anti-rotation seat 18 and a retaining 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 fitted onto the lower end of the floating control rod 17, forming an interference fit with the floating control rod 17. The inner wall of the upper sleeve of the fixed anti-rotation seat 18 forms symmetrically arranged axial grooves on both sides. The retaining shaft 19 passes through the through hole at the lower end of the floating control rod 17, and its two ends are correspondingly arranged in the axial grooves on both sides. The retaining 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 achieving the anti-rotation function of the floating control rod 17.

[0064] In one implementation of this invention, such as Figure 3 As shown, the separation mechanism may also include: pulley block 15.

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

[0066] In specific embodiments, such as Figure 4 As shown, the pulley block 15 includes: pulley 20, wheel frame 21, two bushings 22, pulley shaft 23, retaining ring for elastic shaft 24, and two bearings 25.

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

[0068] Two bearings 25 are fitted at both ends of the shaft hole of the pulley 20, and each bearing 25 is fitted with a bushing 22 for the inner ring of the bearing. After the pulley shaft 23 passes through the shaft hole of the pulley 20 and the two bushings 22, one end passes through the side lug and is locked on the retaining ring 24 for the elastic shaft, and the other end abuts against the other side lug 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, and the bottom small-diameter end forms a tight fit structure with the inner ring of the bearing 7. The outer cylindrical step is in contact with the upper end face of the inner ring of the bearing 7. A groove is provided on the outer cylindrical surface of the small-diameter end, and a locking washer is provided in the groove. The axial movement of the rotating seat 8 is limited by the step and the locking washer.

[0070] In an optional embodiment of the present invention, the drive shaft 12 is configured as a shaft part with a disc body at one end, the shaft body is connected to the drive mechanism 13 by a key, the other end of the disc body has a pin hole at the diagonal, a blind hole is opened in the middle of the bottom end of the disc body, and 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. 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 corresponds 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. The magnet 11 is pressed onto the stepped end face of the stepped through hole. After the floating control rod 17 passes through the stepped through hole, the top limiting 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 motion of the drive mechanism 13 and the separation mechanism is controlled.

[0073] The remote control method of the remote separation control device for enclosed spaces provided in the above embodiments of the present invention is as follows:

[0074] The limiting end at the top of the floating control rod 17 and the magnet 11 repel each other without external force, so that the floating control rod 17 remains floating. The floating control rod 17 drives the locking 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 via 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 locking shaft 19 to the bottom of the fixed anti-rotation seat 18, thereby separating the floating end plate 10 from the drive shaft 12, that is, separating the separation mechanism 13 from the drive mechanism 13, so that neither the separation mechanism 13 nor the rack 9 follows the movement of the drive mechanism 13.

[0076] Based on the remote separation control device for enclosed spaces provided in the above embodiments of the present invention, the present invention also provides a method for using the remote separation control device for enclosed spaces, specifically: a method for separating the drive mechanism 13 and the separation mechanism when the drive mechanism 13 is stuck, for releasing the clamped product, the method of use including:

[0077] Step 1: After the drive mechanism 13 stalls or self-locks, the drive shaft 12 cannot rotate, so the rotating seat 8 cannot move relative to the drive mechanism 13.

[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 are in a free state of movement.

[0079] Step 3, the fixed anti-rotation seat 18 in the anti-rotation mechanism 14 ensures that the control rope 16 does not rotate relative to the gear 9 and the rack 8 during relative motion;

[0080] Step 4: After the stall is released, loosen the wire rope 16 and gently rotate the rotating seat 8 so that the diagonal holes of the rotating seat 8 fall into the pins on the drive shaft 12 during the rotation process.

[0081] Step 5: The rotating seat 8 is connected to the drive shaft 12, and the mechanism resumes normal operation.

[0082] By implementing steps 1 to 5, after separating the drive shaft 12 and gear 8 using the rotating seat 8, the movement of gear 9 and rack 8 is independent of the drive mechanism 13 and is not restricted by the blocking or self-locking of the drive mechanism 13, so as to release the product.

[0083] This invention provides a remote separation control device and its usage method for use in enclosed spaces. It employs a method of separating the drive shaft 12 and gear 9 using a rotating base 8, allowing the transmission system to rotate independently of the drive mechanism 13. The separability of the drive end structure enables rapid separation of the mechanism in self-locking or stall conditions. Utilizing the adjustability and adaptability of the holes between the rotating base 8, gear 9, and drive shaft 12 mounting base, alignment between the holes is achieved, satisfying both the rapid retraction of the mechanism and the timely release of the gear and drive assembly. It also satisfies the instantaneous separability of the mechanism. Through the connection between the anti-rotation mechanism 14 and the wire rope 16, the remote controllability of the device is realized, and the safety and service life of the device are guaranteed. By adjusting the relative position relationship between the pulley block 15 and the wire rope 16, the smoothness and accuracy of the device in the disengagement process are ensured. It not only satisfies the timeliness of the gear and drive components to be released instantly, but also satisfies the instantaneous separability of the mechanism. Its structure is simple, stable and reliable, easy to operate and convenient to control, which greatly ensures the reliability of the equipment in case of emergencies during operation.

After the drive mechanism (13) is running normally, the control rope (16) is released. After the control rope (16) is in a free state, the floating control rod (17) rebounds upward under the repulsive force of the magnet (11). By gently pushing the rack (5), the floating end plate (10) automatically returns to its original position, restoring the linkage between the floating end plate (10) and the drive shaft (12).

The floating control rod (17) drives the locking shaft (19) to move up to the top of the fixed anti-rotation seat (18). When a downward force is applied to the floating control rod (17) via 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 locking shaft (19) to the bottom of the fixed anti-rotation seat (18), thereby separating the floating end plate (10) from the drive shaft (12), that is, separating the separation mechanism from the drive mechanism (13), so that the separation mechanism and the rack (5) do not follow the movement of the drive mechanism (13).
