[0046] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.
[0047] The above background technology has explained that the conventional transmission form of the existing transmission system; and when the driving element is blocked or self-locked, the transmission mechanism cannot move, resulting in a continuous large amount of force output, which causes product damage and equipment damage to a certain extent.
[0048] In order to ensure the safety of products and equipment, it is necessary to release the products under certain force values. In some special cases, the products must be absolutely protected. 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] In view of the important requirement that the transmission system can achieve rapid separation in the event of motor stall or self-locking, improve work efficiency and ensure product safety, the embodiment of the present invention provides a pressure-type rapid escape device and a method of using the same. The pressure-type rapid escape device can be used in various types of equipment that require rapid separation in the event of self-locking. It is a rapid escape device with a simple structure, stable and reliable operation, and convenient control.
[0050] The present invention provides the following specific embodiments which can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
[0051] Figure 1 The present invention provides an overall structural diagram of a pressure-type rapid escape device. Figure 2 for Figure 1 The illustrated embodiment provides a force analysis cross-sectional view of a pressure-type quick escape device. Figure 1 and Figure 2As shown, a pressure-type quick escape device provided by an embodiment of the present invention has a structure including: a driving mechanism 1, a moving end plate 2, a separation 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, the driving mechanism 1 in the embodiment of the present invention is fixedly mounted on the upper end surface of the mounting base 4, the execution end of the driving mechanism 1 is fixedly mounted on the lower end surface of the separation end plate 3, the two linear guide rails 5 are arranged in parallel and symmetrically, and are fixedly mounted on both sides of the upper end surface of the mounting base 4, and three sliders are arranged above each linear guide rail. The moving end plate 2 is fixedly mounted on the two sliders at one end of the two linear guide rails 5, and the separation end plate 3 is fixedly mounted on the slider at the other end of the linear guide rail 5. A certain gap is left between the separation end plate 3 and the moving end plate 2, and the driving mechanism 1 can drive the separation end plate 3 to move independently. The end plate 3 moves along the linear guide rail 5 to ensure the independence of the movement of the moving end plate 2 and the separation end plate 3. A "V"-shaped groove is opened on the upper end surface of the separation end plate 3. The pressure control base 6 is fixedly installed on the front end of the upper end surface of the moving end plate 2 by a locking screw 8. Two pressure control units 7 are installed on the pressure control base 6 in sequence 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 the bottom are half-embedded in the "V"-shaped groove on the upper end surface of the separation end plate 3, forming a connection structure between the moving end plate 2 and the separation end plate 3.
[0053] In the embodiment of the present invention, the disengagement force between the moving end plate 2 and the separation 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 driving mechanism 1 drives the moving end plate 2 to start moving at the execution end, and the driving force value is within the set escape force value, the separation end plate 3 moves with the moving end plate 2, and the pressure control unit 7 is in an 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 the interior thereof and escapes from the "V"-shaped groove of the separation end plate 3, thereby separating the moving end plate 2 from the separation end plate 3 and causing each to move.
[0054] See also Figure 2 As shown, when the opening and closing angle θ of the "V"-shaped groove on the separation 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] Among them, θ1, θ2, θ3 are different slot opening and closing angles, f1, f2, f3 are different stress conditions when the "V"-shaped slot face is squeezed under different slot opening and closing angles, and Δx1, Δx2, Δx3 are different compression amounts of the spring under different stress conditions.
[0060] It can be seen that when the slot opening and closing angle θ increases, the corresponding escape force value becomes smaller.
[0061] On the one hand, the opening and closing angle of the "V"-shaped groove is set according to the required force value, and the required force value can be adjusted by changing the value of θ; on the other hand, the sinking 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 to adjust the size of Δx.
[0062] In the embodiment of the present invention, the pressure control unit 7 includes: a pressure bead 9, a force value adjustment rod 10, a high pressure spring 11, a shell 12, an adjusting nut 13, and a plug 14; wherein the shell 12 is configured to have a structure with a central through hole, the adjusting nut 13 is threadedly installed inside the end of one side of the shell 12, the high pressure spring 11 is embedded and pressed inside the shell 12, a limiting convex ring is provided on the mounting end surface of the plug 14, the pressure bead 9 is inserted into the plug 14 from the open end of the plug 14, and is nested and installed inside the end of the other side of the shell 12 through the plug 14, so that the pressure head of the pressure bead 9 rolls out of the limiting convex ring of the plug 14, and the high pressure spring 11 is pressed between the pressure bead 9 and the adjusting nut 13, and the driving force value is controlled by adjusting the depth of the nut 13 screwed into the shell 12 and adjusting the spring compression amount. In addition, both ends of the force adjustment rod 10 that transversely passes through the center hole of the pressure bead 9 are embedded in the axial elongated grooves on the inner wall of the shell 12, so as to control the pressure bead 9 to move up and down along the axial elongated grooves on the inner wall of the shell 12 when the pressure bead 9 is subjected to the extrusion force, thereby controlling the trajectory of the relative movement of the pressure bead 9; furthermore, the force adjustment rod 10 is located on the inner side of the mounting end face of the plug 14 to limit its axial position by the plug 14.
[0063] In a specific implementation, by setting the matching connection form 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 middle of the outer wall of the shell 12 has a relatively long external thread, which is used to be threadedly connected with two threaded holes at the front end of the pressure control base 6; by adjusting the threaded connection position between the shell 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 one end portion where the shell 12 is connected to the adjusting nut 13 has a longer internal thread, and the adjusting nut 13 is threadedly connected with the internal thread. By adjusting the screwed position of the nut 13 in the shell 12, the compression amount of the high-pressure spring 11 is controlled to achieve the control of the escape force value of the entire pressure control unit 7.
[0066] The shell 12 in the implementation of the present invention also has the following installation structural features: an outer cylindrical surface of one end portion of the shell 12 connected to the plug 14 is formed with an outer ring groove, the outer wall surface of the outer ring groove has an outer thread, the inner side of the plug 14 has an inner thread, and the threads of the plug 14 and the shell 12 cooperate with each other; in addition, an inner cylindrical surface of one end portion of the shell 12 connected to the plug 14 is formed with an inner ring groove, and the inner ring groove has symmetrically arranged long grooves along the axial direction on both sides, and the two ends of the force adjustment rod 10 are respectively embedded in the long grooves on both sides, and move axially in the long grooves.
[0067] In the embodiment of the present invention, the plug 14 is a hollow shell structure, and a limiting convex ring is arranged on its installation end surface, which is arranged as a spherical inner arc surface. The inner wall of the plug 14 is provided with an internal thread, and the internal thread is screwed and fixed with the external thread of the shell 12. The pressure bead 9 passes through the limiting convex ring 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.
[0068] In addition, the spherical surface of the pressure bead 9 located in the limiting convex ring fits with the spherical inner arc surface of the limiting convex ring in the plug 14, the spherical surface at the other end fits with the high pressure spring 11, and the middle part cooperates with the arc groove of the shell 12.
[0069] The working principle of the pressure-type quick escape device provided in the embodiment of the present invention is:
[0070] When the driving force value of the driving 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 located outside the limiting convex ring of the plug 14, fitting with the "V"-shaped 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 value of the driving mechanism 1 exceeds the escape force value preset by the pressure control unit 7, the pressure ball 9 is pressed into the plug 14 by the "V"-shaped groove of the separation end plate 3, so that the high-pressure spring 11 is deeply compressed, and the pressure ball 9 moves upward along the arc groove of the shell 12 and separates from the "V"-shaped 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"-shaped groove is set according to the required force value, and the required force value is adjusted by changing the value of θ. At the same time, the size 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 devices provided in the above embodiments of the present invention, the embodiments of the present invention also provide a method for using the pressure-type rapid escape device when rapid escape is required, including the following steps:

[0080] Step 2, when the drive mechanism 1 is stalled, the driving force value output by the drive mechanism 1 is continuously increased, so that the driving force value gradually approaches the escape force value preset by the drive mechanism 1;
[0081] Step 3, when the driving force value increases to exceed the escape force value, the pressure bead 9 in the pressure control unit 7 is squeezed by the "V"-shaped 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 groups of pressure control units 7 slide out along the "V"-shaped groove on the upper end 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, so that the product set on the moving end plate 2 is unlocked.
[0083] Furthermore, the method of use provided in the embodiment of the present invention also includes presetting the escape force value of the pressure control unit 7, including the following setting methods:
[0084] On the one hand, by adjusting the screwing position of the nut 13 in the housing 12, the compression amount of the high pressure spring 11 is controlled, thereby realizing the setting of the escape force value of the pressure control unit 7;
[0085] On the other hand, by adjusting the opening and closing 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] The embodiment of the present invention provides a pressure-type quick escape device and a method for using the same, which utilizes the structure of the driving end itself, namely the separability of the moving end plate 2 and the separation end plate 3, to achieve quick separation of the mechanism in the case of self-locking or stalling. At the same time, the compression amount and elastic modulus of the high-pressure spring 11 can be adjusted by adjusting the internal groove type of the separation end plate 3 and the movement amount of the adjustment nut 13 along the shell 12 to adjust different force values and different input lengths to adapt to different working conditions and different requirements for disengagement force values.
