Technical Field

[0001] This invention relates to, but is not limited to, the field of pressure-based rapid escape technology, and particularly to a pressure-based rapid escape device and its method of use. Background Technology

[0002] In common transmission systems, a combination of motor and reducer is usually used to achieve the power input of the motion system, and linear guide rails are used for transmission. However, during the motion process, the driving components often stall or self-lock.

[0003] In this situation, the entire motion system will be at a standstill, all transmission mechanisms will be unable to move, and a large amount of force will continue to be output, causing a certain degree of product and equipment damage. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned technical problems. This invention provides a pressure-type rapid escape device and its usage method to solve the problem that in existing transmission systems, when the driving component is stalled or self-locked, the transmission mechanism cannot move, resulting in a continuous large output of force, which causes product and equipment damage to a certain extent.

[0005] The technical solution of the present invention: In a first aspect, the embodiments of the present invention provide a pressure-type rapid escape device, comprising: a drive mechanism 1, a moving end plate 2, a separating end plate 3, a mounting base 4, at least two linear guide rails 5, and a pressure control module;

[0006] At least two linear guide rails 5 are arranged in parallel and symmetrically, and are fixedly installed on both sides of the upper surface of the mounting base 4. Each linear guide rail is provided with at least two sliders. The moving end plate 2 is fixedly installed on at least one slider at one end of the two linear guide rails 5, and the separating end plate 3 is fixedly installed on at least one slider at the other end of the linear guide rails 5. The fixed end of the driving mechanism 1 is fixedly installed on the mounting base 4, and the executing end is fixedly installed on the lower surface of the separating end plate 3. The separating end plate 3 is used to move along the linear guide rails 5 under the drive of the driving mechanism 1. A "V" shaped groove perpendicular to the direction of the linear guide rails 5 is opened on the side of the upper surface of the separating end plate 3 near the moving end plate 2.

[0007] The pressure control module is fixedly installed on the upper surface of the moving end plate 2 near the separating end plate. The elastic component at the bottom of the pressure control unit 7 installed at the rear end of the pressure control module is partially embedded in the "V" groove of the separating end plate 3. The moving end plate 2 and the separating end plate 3 are connected through the pressure control module and the pressure control unit 7. When the driving force received by the separating end plate 3 exceeds the preset escape force value, the elastic component at the bottom of the pressure control unit 7 is pressed into the pressure control unit 7 by the "V" groove, thereby separating the separating end plate 3 from the moving end plate 2 and allowing the moving end plate 2 and the separating end plate 3 to move independently.

[0008] Optionally, in the pressure-type rapid escape device described above, the pressure control module includes: a pressure control base 6 and a pressure control unit 7;

[0009] The pressure control base 6 includes an integral mounting base and a connecting base. The connecting base is configured as a boss structure extending out of the top of the mounting base. The pressure control unit 7 is fixedly connected to the side of the moving end plate 2 near the separating end plate 3 through the mounting base, so that the connecting part is located above the "V" groove of the separating end plate 3. The separating end plate 3 has at least one mounting hole for corresponding fixed mounting of the pressure control unit 7.

[0010] When multiple mounting holes are opened on the separation end plate 3, multiple pressure control units 7 are arranged and installed along the "V" groove direction, so that the elastic components at the bottom of the pressure control unit 7 are all semi-embedded in the "V" groove of the separation end plate 3.

[0011] Optionally, in the pressure-type rapid escape device described above, the pressure control unit 7 includes: a pressure bead 9, a force adjustment rod 10, a high-pressure spring 11, a housing 12, an adjusting nut 13, and a plug 14;

[0012] The housing 12 is configured with a central through hole. An adjusting nut 13 is screwed into the inside of one end of the housing 12. A high-pressure spring 11 is embedded and press-fitted into the housing 12. A limiting protrusion ring is provided on the mounting end face of the plug 14. A pressure bead 9 is fitted into the plug 14 from the open end and is nested in the other end of the housing 12 through the plug 14, so that the pressure head of the pressure bead 9 rolls out of the limiting protrusion ring of the plug 14, and presses the high-pressure spring 11 between the pressure bead 9 and the adjusting nut 13. The driving force value is controlled by adjusting the depth of the adjusting nut 13 screwed into the housing 12 to adjust the spring compression.

[0013] The force adjustment rod 10 passes laterally through the center hole of the pressure bead 9, and its two ends are embedded in the axial elongated grooves on the inner wall of the housing 12. It controls the pressure bead 9 to move up and down along the axial elongated grooves on the inner wall of the housing 12 when it is subjected to compressive force, thereby controlling the trajectory of the relative movement of the pressure bead 9. The force adjustment rod 10 is located inside the mounting end face of the plug 14 so that the axial position of the force adjustment rod 10 is limited by the plug 14.

[0014] Optionally, in the pressure-type rapid escape device as described above;

[0015] The outer wall of the housing 12 has an external thread of a preset length in the middle, which is used to engage with the threaded hole on the connecting seat in the pressure control base 6 for screwing; by adjusting the threaded connection position between the housing 12 and the pressure control base 6, the driving force value of the entire pressure control unit 7 can be adjusted.

[0016] The inner wall surface of the end of the housing 12 connected to the adjusting nut 13 has an internal thread of a preset length. The adjusting nut 13 is screwed into the internal thread. By adjusting the screw position of the adjusting nut 13 in the housing 12, the compression of the high-pressure spring 11 is controlled, thereby setting the escape force value of the pressure control unit 7.

[0017] Optionally, in the pressure-type rapid escape device as described above;

[0018] The outer cylindrical surface of the end of the housing 12 connected to the plug 14 has an outer annular groove, the outer wall of the outer annular groove has an external thread, the inner side of the plug 14 has an internal thread, and the threads of the plug 14 and the housing 12 are mutually engaged.

[0019] The inner cylindrical surface of the end of the housing 12 connected to the plug 14 has an inner annular groove. The inner annular groove has symmetrically opened elongated grooves along the axial direction on both sides. The two ends of the force adjustment rod 10 are respectively embedded in the elongated grooves on both sides and move along the axial direction within the elongated grooves.

[0020] Optionally, in the pressure-type rapid escape device as described above;

[0021] The limiting protrusion on the mounting end face of the plug 14 is set as a spherical inner arc surface. The inner side wall of the plug 14 is provided with an internal thread. The internal thread is screwed and fixed with the external thread of the housing 12. The pressure bead 9 passes through the limiting protrusion of the plug 14 and exposes 1 / 4 of the pressure head. The spherical inner arc surface of the plug 14 cooperates with the pressure bead 9 to limit the movement position of the pressure bead 9.

[0022] The spherical surface of the pressure bead 9 located inside the limiting protrusion ring is in contact with the spherical inner arc surface of the limiting protrusion ring in the plug 14, and the spherical surface at the other end is in contact with the high-pressure spring 11, while the middle part is in contact with the arc groove of the housing 12.

[0023] Optionally, in the pressure-type rapid escape device as described above;

[0024] When the driving force of the drive mechanism 1 is within the escape force value preset by the pressure control unit 7, the high pressure spring 11 is only slightly compressed, and the pressure head of the pressure bead 9 is still outside the limiting protrusion of the plug 14, and is in contact with the "V" groove of the separation end plate 3, and can drive the separation end plate 3 and the moving end plate 2 to move together.

[0025] When the driving force of the drive mechanism 1 exceeds the escape force value preset by the pressure control unit 7, the pressure bead 9 is pressed into the plug 14 by the "V" groove of the separation end plate 3, causing the high pressure spring 11 to be deeply compressed. The pressure bead 9 moves upward along the arc groove of the housing 12 and separates from the "V" groove of the separation end plate 3. The moving end plate 2 and the separation end plate 3 are separated and move independently.

[0026] Optionally, in the pressure-type rapid escape device as described above;

[0027] Its characteristic is that by setting the opening and closing angle θ of the "V"-shaped groove on the separation end plate 3, the component of the escape force value of the drive mechanism 1 at the opening and closing angle of the groove is obtained;

[0028] F = f*sinθ1 = Δx*k;

[0029] Where F represents the force on the spring in a vertical position, f represents the force on the steel ball when it is compressed by the "V" shaped groove, and θ is the angle between the horizontal plane and the groove plane.

[0030] Secondly, a method of using a reel-type lifting and towing device, comprising the following steps, for towing a high-altitude refueling hose using a pressure-type rapid escape device as described in any of the above claims:

[0031] Step 1: When the drive mechanism 1 is operating normally, the actuator of the drive mechanism 1 drives the separation end plate 3 to move along the linear guide rail 5, and the separation end plate 3 drives the moving end plate 2 through the pressure control unit 7.

[0032] Step 2: When the drive mechanism 1 stalls, the driving force output by the drive mechanism 1 continuously increases, causing the driving force to gradually approach the preset escape force value of the drive mechanism 1.

[0033] Step 3: When the driving force increases to exceed the escape force, the pressure bead 9 in the pressure control unit 7 is squeezed by the "V" groove in the separation end plate 3 and pressed into the plug 14 of the pressure control unit 7.

[0034] Step 4: The pressure beads 9 at the bottom of the two pressure control units 7 slide out along the "V" groove on the upper surface of the separation end plate 3, so that the separation end plate 3 and the moving end plate 2 are separated from each other, and the product set on the moving end plate 2 is unlocked.

[0035] Optionally, in the method of using the pressure-type rapid escape device as described above, before step 1, the method further includes:

[0036] The escape force value of the pressure control unit 7 is set; including the following setting methods:

[0037] Method 1: By adjusting the screw-in position of the nut 13 inside the housing 12, the compression of the high-pressure spring 11 is controlled, thereby setting the escape force value of the pressure control unit 7.

[0038] Method 2: The escape force value of the pressure control unit 7 is set by adjusting the opening angle θ of the "V" shaped groove on the separation end plate 3.

[0039] The beneficial effects of the present invention are as follows: The embodiments of the present invention provide a pressure-type rapid escape device and its usage method. By utilizing the separability of the drive end structure, namely the moving end plate 2 and the separating end plate 3, the mechanism can achieve rapid separation under self-locking or stall conditions. At the same time, the compression and elastic modulus of the high-pressure spring 11 can be adjusted by adjusting the internal groove shape of the separating end plate 3 and the amount of movement of the adjusting nut 13 along the housing 12 to achieve different force values ​​and different input lengths to adapt to different working conditions and different separation force requirements. Through its own rapid adjustment and the strong self-adaptability of the mechanism, the overpressure protection can be opened under special conditions to complete the release of the necessary product. At the same time, by controlling the motion trajectory, the smoothness of the mechanism compression is ensured. 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.

[0046] 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.

[0047] As explained in the background section, existing transmission systems use conventional transmission methods; and when the driving component is stalled or self-locked, the transmission mechanism cannot move, resulting in a continuous and large output of force, which can cause product and equipment damage to a certain extent.

[0048] To ensure the safety of products and equipment, the products need to be released under a certain force value to provide absolute protection for the products in some special circumstances. Therefore, rapid separation is required in emergency situations. In some emergency situations, the mechanism itself needs to have a self-unlocking and self-escape function.

[0049] To address the important requirement of achieving rapid separation in the event of motor stall or self-locking, thereby improving work efficiency and ensuring product safety, this invention provides a pressure-type rapid escape device and its usage method. This pressure-type rapid escape device can be used in various devices that require rapid separation in the event of self-locking. It is a rapid escape device with simple structure, stability, reliability, easy operation, and convenient control.

[0050] 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.

[0051] Figure 1 This is a schematic diagram of the overall structure of a pressure-type rapid escape device provided in an embodiment of the present invention. Figure 2 for Figure 1 The illustrated embodiment provides a force analysis cross-sectional view of a pressure-type rapid escape device. See also... Figure 1 and Figure 2As shown in the figure, the pressure-type rapid escape device provided in this embodiment of the invention includes: a drive mechanism 1, a moving end plate 2, a separating end plate 3, a mounting base 4, two linear guide rails 5, and a pressure control module; wherein the pressure control module includes a pressure control base 6, two pressure control units 7, and two locking screws 8.

[0052] like Figure 1 and Figure 2 As shown, in this embodiment of the invention, the drive mechanism 1 is fixedly installed on the upper surface of the mounting base 4, and the actuator of the drive mechanism 1 is fixedly installed on the lower surface of the separation end plate 3. Two linear guide rails 5 are arranged in parallel and symmetrically, and are fixedly installed on both sides of the upper surface of the mounting base 4. Three sliders are arranged above each linear guide rail. The motion end plate 2 is fixedly installed on two sliders at one end of the two linear guide rails 5, and the separation end plate 3 is fixedly installed on the sliders at the other end of the linear guide rails 5. A certain gap is left between the separation end plate 3 and the motion end plate 2, so that the drive mechanism 1 can drive the separation end plate 3 independently. The end plate 3 moves along the linear guide rail 5, ensuring the independent movement of the moving end plate 2 and the separating end plate 3. The upper surface of the separating end plate 3 has a "V" shaped groove. The pressure control base 6 is fixedly installed at the front end of the upper surface of the moving end plate 2 by locking screws 8. Two pressure control units 7 are arranged sequentially on the pressure control base 6 in the direction of the "V" shaped groove. After the lower ends of the two pressure control units 7 pass through the pressure control base 6, the elastic components at their bottoms are semi-embedded in the "V" shaped groove on the upper surface of the separating end plate 3, forming a connection structure between the moving end plate 2 and the separating end plate 3.

[0053] In this embodiment of the invention, the separation force between the moving end plate 2 and the separating end plate 3 can be calibrated by controlling the extension amount of the elastic component at the bottom of the pressure control unit 7 and the opening and closing angle of the "V"-shaped groove. When the actuator of the drive mechanism 1 drives the moving end plate 2 to start moving, if the driving force value is within the set escape force value, the separating end plate 3 moves together with the moving end plate 2, and the pressure control unit 7 is in the extended state. When the driving force value continues to increase until it exceeds the escape force value, the elastic component at the bottom of the pressure control unit 7 is pressed into its interior and escapes from the "V"-shaped groove of the separating end plate 3, thereby causing the moving end plate 2 and the separating end plate 3 to separate and move independently.

[0054] See Figure 2 As shown, when the opening angle θ of the "V" shaped groove on the separating end plate 3 changes,

[0055] F1=f1*sinθ1=Δx1*k

[0056] F2=f2*sinθ2=Δx2*k

[0057] F3=f3*sinθ3=Δx3*k

[0058] 0°≤θ≥90°

[0059] Wherein, θ1, θ2, and θ3 are different opening and closing angles of the groove, f1, f2, and f3 are different force conditions under the compression of the "V"-shaped groove surface at different opening and closing angles of the groove, and Δx1, Δx2, and Δx3 are different compression amounts of the spring under different force conditions.

[0060] It can be seen that as the opening angle θ of the groove increases, the corresponding escape force value decreases.

[0061] On the one hand, the opening and closing angle of the "V" groove is set according to the required force value. By changing the value of θ, the required force value can be adjusted. On the other hand, the depth of the elastic component at the bottom of the pressure control unit 7 and the different elastic moduli of different springs are adjusted according to the required force value, thereby adjusting the value of Δx.

[0062] In this embodiment of the invention, the pressure control unit 7 includes: a pressure bead 9, a force adjustment rod 10, a high-pressure spring 11, a housing 12, an adjusting nut 13, and a plug 14. The housing 12 is configured with a central through hole. The adjusting nut 13 is screwed into the interior of one end of the housing 12. The high-pressure spring 11 is embedded and press-fitted into the housing 12. A limiting protrusion is provided on the mounting end face of the plug 14. The pressure bead 9 is fitted into the plug 14 from its open end and is nested inside the housing 12 on the other end, causing the pressure head of the pressure bead 9 to roll out of the limiting protrusion of the plug 14. The high-pressure spring 11 is press-fitted between the pressure bead 9 and the adjusting nut 13. The driving force is controlled by adjusting the depth to which the adjusting nut 13 is screwed into the housing 12 and adjusting the spring compression. In addition, the two ends of the force adjustment rod 10, which is transversely penetrating the center hole of the pressure bead 9, are embedded in the axial elongated groove on the inner wall of the housing 12. This controls the pressure bead 9 to move up and down along the axial elongated groove on the inner wall of the housing 12 when it is subjected to compressive force, thereby controlling the trajectory of the relative movement of the pressure bead 9. Furthermore, the force adjustment rod 10 is located inside the mounting end face of the plug 14 so that its axial position is restricted by the plug 14.

[0063] In practical implementation, by setting the connection method between the housing 12 and each structure, the pressure control unit 7 can be controlled to adjust the force value, and has the following adjustment capabilities:

[0064] On the one hand, the outer wall of the housing 12 has a long external thread in the middle, which is used to screw into the pressure control base 6 with two threaded holes at the front end; by adjusting the threaded connection position between the housing 12 and the pressure control base 6, the driving force value of the entire pressure control unit 7 can be adjusted.

[0065] On the other hand, the inner wall surface of the end of the housing 12 connected to the adjusting nut 13 has a long internal thread. The adjusting nut 13 is screwed into the internal thread. By adjusting the screw position of the adjusting nut 13 in the housing 12, the compression of the high pressure spring 11 is controlled so as to control the escape force value of the entire pressure control unit 7.

[0066] The housing 12 in this embodiment of the invention also has the following installation structure features: an outer annular groove is formed on the outer cylindrical surface of the side end where the housing 12 is connected to the plug 14, the outer wall surface of the outer annular groove has an external thread, the inner side of the plug 14 has an internal thread, and the plug 14 and the housing 12 are threaded to each other; in addition, an inner annular groove is formed on the inner cylindrical surface of the side end where the housing 12 is connected to the plug 14, and axial elongated grooves are symmetrically opened on both sides of the inner annular groove, and the two ends of the force adjustment rod 10 are respectively embedded in the elongated grooves on both sides and move axially within the elongated grooves.

[0067] In this embodiment of the invention, the plug 14 is a hollow shell structure. A limiting protrusion is provided on its mounting end face, which is set as a spherical inner arc surface. The inner sidewall of the plug 14 is provided with an internal thread, which is screwed and fixed with the external thread of the shell 12. The pressure bead 9 passes through the limiting protrusion of the plug 14 and exposes 1 / 4 of the pressure head. The spherical inner arc surface of the plug 14 cooperates with the pressure bead 9, which restricts the movement position of the pressure bead 9.

[0068] In addition, the spherical surface of the pressure bead 9 located inside the limiting protrusion ring is in contact with the spherical inner arc surface of the limiting protrusion ring in the plug 14, and the spherical surface at the other end is in contact with the high-pressure spring 11, while the middle part is in contact with the arc groove of the housing 12.

[0069] The working principle of the pressure-type rapid escape device provided in this embodiment of the invention is as follows:

[0070] When the driving force of the drive mechanism 1 is within the escape force value preset by the pressure control unit 7, the high pressure spring 11 is only slightly compressed, and the pressure head of the pressure bead 9 is still outside the limiting protrusion of the plug 14, and is in contact with the "V" groove of the separation end plate 3, and can drive the separation end plate 3 and the moving end plate 2 to move together.

[0071] When the driving force of the drive mechanism 1 exceeds the escape force value preset by the pressure control unit 7, the pressure bead 9 is pressed into the plug 14 by the "V" groove of the separation end plate 3, causing the high pressure spring 11 to be deeply compressed. The pressure bead 9 moves upward along the arc groove of the housing 12 and separates from the "V" groove of the separation end plate 3. The moving end plate 2 and the separation end plate 3 are separated and move independently.

[0072] When the opening and closing angle of the "V" shaped groove on the moving end plate 2 changes,

[0073] F1=f1*sinθ1=Δx*k1

[0074] F2=f2*sinθ2=Δx*k2

[0075] F3=f3*sinθ3=Δx*k3

[0076] 0≤θ≥90

[0077] F1 < F2 < F3. The opening and closing angle of the "V" groove is set according to the required force value. The required force value is adjusted by changing the value of θ. At the same time, the value of Δx is adjusted according to the required sinking depth of the pressure control unit 7 and the different elastic moduli of different springs.

[0078] Based on the pressure-type rapid escape device provided in the above embodiments of the present invention, the present invention also provides a method of using the pressure-type rapid escape device when rapid escape is required, including the following steps:

[0079] Step 1: When the drive mechanism 1 is operating normally, the actuator of the drive mechanism 1 drives the separation end plate 3 to move along the linear guide rail 5, and the separation end plate 3 drives the moving end plate 2 through the pressure control unit 7.

[0080] Step 2: When the drive mechanism 1 stalls, the driving force output by the drive mechanism 1 continuously increases, causing the driving force to gradually approach the preset escape force value of the drive mechanism 1.

[0081] Step 3: When the driving force increases to exceed the escape force, the pressure bead 9 in the pressure control unit 7 is squeezed by the "V" groove in the separation end plate 3 and pressed into the plug 14 of the pressure control unit 7.

[0082] Step 4: The pressure beads 9 at the bottom of the two pressure control units 7 slide out along the "V" groove on the upper surface of the separation end plate 3, so that the separation end plate 3 and the moving end plate 2 are separated from each other, and the product set on the moving end plate 2 is unlocked.

[0083] Furthermore, the usage method provided in this embodiment of the invention also includes pre-setting the escape force value of the pressure control unit 7, including the following setting methods:

[0084] On the one hand, by adjusting the screw-in position of the nut 13 inside the housing 12, the compression of the high-pressure spring 11 is controlled, thereby setting the escape force value of the pressure control unit 7;

[0085] On the other hand, by adjusting the opening angle θ of the "V"-shaped groove on the separation end plate 3, the escape force value of the pressure control unit 7 can be set.

[0086] This invention provides a pressure-type rapid escape device and its usage method. Utilizing the separability of the drive end plate 2 and the separation end plate 3, the device achieves rapid separation under self-locking or stall conditions. Simultaneously, by adjusting the internal groove shape of the separation end plate 3 and the movement of the adjusting nut 13 along the housing 12, the compression and elastic modulus of the high-pressure spring 11 can be adjusted to achieve different force values ​​and input lengths to adapt to different working conditions and varying separation force requirements. Through its rapid adjustment and strong self-adaptability, the device enables overpressure protection to open under special circumstances to release the necessary product. Furthermore, by controlling the motion trajectory, the smoothness of the compression mechanism is ensured. Its simple structure, stability, reliability, ease of operation, and convenient control greatly guarantee the reliability of the equipment in the event of emergencies during operation.

[0087] While the embodiments disclosed in this invention are as described above, they are merely illustrative of the embodiments to facilitate understanding of the invention and are not intended to limit the invention. Any person skilled in the art to which this invention pertains may make any modifications and variations in the form and details of the implementation without departing from the spirit and scope disclosed herein; however, the scope of patent protection for this invention shall still be determined by the scope defined in the appended claims.
