Description

Technical Field

[0001] This invention belongs to the technical field of safety clamp equipment, specifically relating to an electromechanical safety clamp. Background Technology

[0002] Existing electronic safety brakes mainly rely on electromagnetic force for direct triggering or electromagnetic force to hold a compressed spring, triggering after power failure. The electronic triggering force or spring force after power failure triggers the safety brake to clamp the guide rail and brake. The safety brake reset is achieved by the elevator reversing. Due to space and electromagnetic force limitations, the safety brake cannot obtain a large holding force when triggered, which can easily lead to the safety brake not being able to brake effectively and reliably at high speeds. On the other hand, when the elevator is not triggered by a fault, the elevator needs to be running to complete the reset operation. During the elevator's reset process or under maintenance, the elevator also needs to be in a safety detection and protection state. The core problem of existing electronic safety brakes is the limited triggering and holding force, resulting in insufficient reliability of braking under high-speed impacts. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing an electromechanical safety clamp.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an electromechanical safety clamp, comprising a trigger reset mechanism and a safety clamp. The safety clamp includes a clamp body, one side of which has a guide rail channel through which a guide rail body passes. One side of the guide rail channel has a wedge mounting groove and the other side has a roller mounting groove. A wedge assembly is movably disposed in the wedge mounting groove, and a roller assembly is movably disposed in the roller mounting groove. The wedge assembly and the roller assembly are respectively located on both sides of the guide rail body. A mounting frame is connected to the outside of the clamp body. A movable frame is movably disposed on one end of the mounting frame away from the clamp body. The movable frame is connected to the roller assembly through a linkage mechanism. The trigger reset mechanism includes a compression spring trigger mechanism disposed between the movable frame and the mounting frame and capable of moving the movable frame away from the mounting frame, and a reset drive mechanism capable of moving the movable frame towards the mounting frame. On the other side of the mounting bracket, away from the clamp body, is a power-off triggered compression spring retaining mechanism connected to the movable frame. This mechanism, through a reset drive mechanism, obtains a large triggering and retaining force, ensuring reliable braking of the safety clamp. Simultaneously, during the reset process, a non-locking mechanism achieves intermittent triggering braking, keeping the elevator in a safe state at all times. The power-off triggered compression spring retaining mechanism, when energized, keeps the linkage mechanism and roller assembly in a retracted state via the compression spring trigger mechanism, ensuring normal elevator operation. When power is off, the mechanism drives the linkage mechanism and roller assembly to brake the guide rail body via the compression spring trigger mechanism. The reset drive mechanism has a large output force to reset the compression spring trigger mechanism, ensuring a successful reset, thereby causing the linkage mechanism to reset the roller assembly.

[0005] In the aforementioned electromechanical safety clamp, the roller assembly includes a brake roller disposed in a roller mounting groove. One end of the brake roller has a roller shaft. The outer side of the roller mounting groove is closed by a roller groove side plate, and a roller guide groove that is bent and inclined away from the guide rail channel is provided on the roller groove side plate. The roller shaft is slidably disposed in the roller guide groove. The roller mounting groove can be closed by the roller groove side plate, and the brake roller can be easily disposed in the roller guide groove by the roller shaft. The roller guide groove can limit and guide the brake roller.

[0006] In the aforementioned electromechanical safety clamp, the side of the roller mounting groove away from the guide rail channel has a mounting groove curved surface that is inclined in the direction away from the guide rail channel and cooperates with the outer side of the brake roller. The brake roller has an annular protrusion on the outer side of its middle circumferential direction. The mounting groove curved surface has a curved track that cooperates with the annular protrusion. The mounting groove curved surface can provide support when the brake roller slides through the roller guide groove, ensuring the sliding stability of the brake roller. The annular protrusion has a braking surface, which can ensure the braking and stopping effect of the annular protrusion. The curved track can facilitate the sliding stability of the annular protrusion in the roller mounting groove.

[0007] In the aforementioned electromechanical safety clamp, the compression spring triggering mechanism includes a guide rod located on the outer side of the mounting frame away from the clamp body and extending axially in the direction away from the mounting frame. The guide rod has a guide limiting part at the end away from the mounting frame. The movable frame is slidably mounted on the guide rod, and a compression spring is sleeved on the guide rod between the movable frame and the mounting frame. The other end of the guide rod has a spring positioning part. One end of the compression spring sleeved on the guide rod abuts against the spring positioning part, and the other end abuts against the guide limiting part. The guide limiting part is connected to the reset drive mechanism and the linkage mechanism through the movable frame. The linkage mechanism enables the compression spring to control the braking state of the roller assembly, and the reset drive mechanism enables the compression spring to be compressed. The linkage mechanism ensures the retracted state of the roller assembly.

[0008] In the aforementioned electromechanical safety clamp, the reset drive mechanism includes a power base located on the inner side of the mounting frame away from the clamp body. A reset motor is located at one end of the power base, and the reset motor is connected to a reset gear located on the outer side of the power base. One end of a columnar reset rack is connected to the inner side of the movable frame. The other end of the reset rack slides into the inner side of the mounting frame and meshes with the reset gear. A rack limiting part is located on the inner side of the movable frame and abuts against the outer side of the mounting frame. The reset motor drives the reset gear to rotate, and the reset gear and reset rack control the axial displacement of the movable frame. The compression spring is compressed via the guide limiting part, and the rack limiting part limits the stroke of the reset rack, ensuring the stability of the reset operation.

[0009] In the aforementioned electromechanical safety clamp, the power-off triggered compression spring retaining mechanism includes an electromagnet mounting base located at the end of the mounting frame away from the clamp body and away from the movable frame. An electromagnet is mounted on the electromagnet mounting base. The electromagnet cooperates with the movable frame through a lever-type retaining assembly that keeps the compression spring in a compressed state. The electromagnet mounting base facilitates the fixation of the electromagnet on the mounting frame. The electromagnet, when energized, controls the lever-type retaining assembly to control the compression spring's contraction state. When the electromagnet is energized, it controls the lever-type retaining assembly to apply resistance, ensuring the compression spring remains compressed. When the electromagnet is de-energized, the resistance of the lever-type retaining assembly disappears, and the compression spring extends. The compression spring can then drive the roller assembly via a linkage mechanism for rapid braking to a stop.

[0010] In the aforementioned electromechanical safety clamp, the lever-type retaining assembly includes a retaining lever that is hinged in the middle at the end of the electromagnet mounting base away from the mounting frame and is curved. One end of the retaining lever acts on the driving end of the electromagnet, and the other end is rotatably equipped with a roller. One side of the movable frame has a movable extension frame extending to the side of the electromagnet mounting base. The movable extension frame is fixedly connected to a movable plate located outside the electromagnet mounting base and extending axially along the electromagnet mounting base. One end of the movable plate passes through the inner side of the electromagnet mounting base, and the other end of the movable plate has a bent portion that bends towards the end away from the retaining lever and abuts against the roller. In the energized state, the driving end of the electromagnet can abut and limit the retaining lever. The roller of the retaining lever is located in the bent portion and can abut and limit the movable plate. The movable frame is connected to the movable plate through the movable extension frame. The movable plate can drive the movable frame to move axially through the movable extension frame. By limiting the movable plate, the movable frame can be limited, ensuring the compression state of the compression spring and the retracted state of the roller assembly.

[0011] In the aforementioned electromechanical safety clamp, a safety clamp trigger detection switch assembly is provided between the movable extension frame and the mounting frame. The safety clamp trigger detection switch assembly is the micro switch disclosed in publication number CN 116513909 A, and the mounting clamp trigger detection switch assembly is capable of detecting the reset state of the brake roller, which is a prior art reference.

[0012] In the aforementioned electromechanical safety clamp, the mounting bracket is located on one side of the clamp body in the horizontal direction, and the movable frame and the power-off triggered compression spring retaining mechanism are respectively located on both sides of the movable frame at the end away from the mounting bracket in the horizontal direction. The linkage mechanism includes a return lever that is bent and hinged in the middle to the roller groove side plate. One end of the return lever is hinged to the roller shaft, and the other end of the return lever is hinged to one end of the first connecting rod. The other end of the first connecting rod is hinged to the movable frame. The movable frame can move by moving the movable plate, which can drive the first connecting rod to move, thereby controlling the braking state of the brake roller through the return lever.

[0013] In the aforementioned electromechanical safety clamp, the mounting bracket is located at one end of the clamp body in the vertical direction and is arranged vertically above the clamp body. The movable frame and the power-off triggered compression spring retaining mechanism are respectively located on both sides of the movable frame at the end away from the mounting bracket in the vertical direction, and the movable frame and the power-off triggered compression spring retaining mechanism are located on both sides of the guide rail. The linkage mechanism includes a second linkage, one end of which is hinged to the roller shaft and the other end of which is hinged to the movable frame.

[0014] Compared with existing technologies, the advantages of this invention are:

[0015] 1. Through the electromechanical design, a larger triggering and holding force can be obtained, making the triggering and braking process of the safety clamp more reliable;

[0016] 2. Through the non-locking mechanism, the safety clamp is in a safe protection state during the reset process, and there is no failure of the safety protection function due to the reset gap;

[0017] 3. By resetting the motor, the automatic reset of the triggering device and safety can be effectively solved in non-faulty conditions;

[0018] 4. This trigger reset mechanism can be used as a stand-alone device and is compatible with conventional safety clamps. Attached Figure Description

[0026] Example 1

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] like Figure 1 , Figure 2 , Figure 3As shown, the electromechanical safety clamp includes a trigger reset mechanism and a safety clamp. The safety clamp includes a clamp body 1. One side of the clamp body 1 has a guide rail channel 11 for a guide rail 2 to pass through. The guide rail channel 11 facilitates the guide rail 2 to pass through the clamp body 1, allowing the clamp body 1 to brake the guide rail 2. One side of the guide rail channel 11 has a wedge mounting groove 12 and the other side has a roller mounting groove 13. A wedge assembly 3 is movably disposed in the wedge mounting groove 12, and a roller assembly 4 is movably disposed in the roller mounting groove 13. The wedge assembly 3 is a current... According to technical specifications, the wedge assembly 3 can be easily installed via the wedge mounting groove 12, and the roller assembly 4 can be easily installed via the roller mounting groove 13. The wedge assembly 3 and the roller assembly 4 are located on opposite sides of the guide rail body 2. A mounting bracket 5 is connected to the outer side of the clamp body 1. A movable bracket 6 is movably mounted on the side of the mounting bracket 5 away from the clamp body 1. The movable bracket 6 is connected to the roller assembly 4 via a linkage mechanism 7. The trigger reset mechanism includes a pressure rod disposed between the movable bracket 6 and the mounting bracket 5, which allows the movable bracket 6 to move away from the mounting bracket 5. The system includes a spring-triggered mechanism 8 and a reset drive mechanism 9 that allows the movable frame 6 to move towards the mounting frame 5. A power-off triggered compression spring holding mechanism 10, connected to the movable frame 6, is located on the other side of the mounting frame 5 away from the clamp body 1. This trigger reset mechanism, through the reset drive mechanism 9, obtains a large trigger holding force to achieve reliable braking of the safety clamp. Simultaneously, during the reset process, a non-locking mechanism achieves non-intermittent trigger braking, ensuring the elevator remains in a safe state. The power-off triggered compression spring holding mechanism 10, when energized, can keep the linkage mechanism 7 and roller assembly 4 in a retracted state through the compression spring trigger mechanism 8, ensuring normal elevator operation. When the power-off triggered compression spring holding mechanism 10 is de-energized, it can drive the linkage mechanism 7 and roller assembly 4 to brake the guide rail 2 through the compression spring trigger mechanism 8. Furthermore, the reset drive mechanism 9 has a large output force that allows the compression spring trigger mechanism 8 to reset, ensuring the reset effect, thereby causing the linkage mechanism 7 to drive the roller assembly 4 to reset.

[0029] Specifically, the roller assembly 4 includes a brake roller 41 disposed in the roller mounting groove 13. One end of the brake roller 41 has a roller shaft 42. The outer side of the roller mounting groove 13 is closed by a roller groove side plate 43. A roller guide groove 44 is provided on the roller groove side plate 43, which is bent and inclined in the direction away from the guide rail channel 11. The roller shaft 42 is slidably disposed in the roller guide groove 44. The roller mounting groove 13 can be closed by the roller groove side plate 43, and the brake roller 41 can be easily disposed in the roller guide groove 44 by the roller shaft 42. The roller guide groove 44 can limit and guide the brake roller 41.

[0030] The roller mounting groove 13 has a mounting groove curved surface 131 on the side away from the guide rail channel 11, which is inclined in the direction away from the guide rail channel 11 and cooperates with the outer side of the brake roller 41. The brake roller 41 has an annular protrusion 411 on the outer side of the middle circumferential direction. The mounting groove curved surface 131 has a curved track 132 that cooperates with the annular protrusion 411. The mounting groove curved surface 131 can provide support when the brake roller 41 slides through the roller guide groove 44, ensuring the sliding stability of the brake roller 41. The annular protrusion 411 has a braking surface, which can ensure the braking and stopping effect of the annular protrusion 411. The curved track 132 can facilitate the sliding stability of the annular protrusion 411 in the roller mounting groove 13.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the compression spring triggering mechanism 8 includes a guide rod 81 located on the outer side of the mounting frame 5 away from the clamp body 1 and extending axially in the direction away from the mounting frame 5. The guide rod 81 has a guide limiting part 82 at the end away from the mounting frame 5. The movable frame 6 is slidably mounted on the guide rod 81, and a compression spring 83 is provided between the movable frame 6 and the mounting frame 5 and sleeved on the guide rod 81. The other end of the guide rod 81 has a spring positioning part. One end of the compression spring 83 sleeved on the guide rod 81 abuts against the spring positioning part, and the other end abuts against the guide limiting part 82. The guide limiting part 82 is connected to the reset drive mechanism 9 and the linkage mechanism 7 through the movable frame 6. The linkage mechanism 7 enables the compression spring 83 to control the braking state of the roller assembly 4, and the reset drive mechanism 9 enables the compression spring 83 to be compressed. The linkage mechanism 7 ensures the retracted state of the roller assembly 4.

[0032] Furthermore, the reset drive mechanism 9 includes a power seat 91 located on the inner side of the mounting frame 5 away from the clamp body 1. A reset motor 92 is provided at one end of the power seat 91. The reset motor 92 is connected to a reset gear 93 located on the outer side of the power seat 91. The inner side of the movable frame 6 is connected to one end of a columnar reset rack 94. The other end of the reset rack 94 slides into the inner side of the mounting frame 5 and meshes with the reset gear 93. The reset rack 94 is provided with a rack limiting part 95 located on the inner side of the movable frame 6 and abutting against the outer side of the mounting frame 5. The reset motor 92 can drive the reset gear 93 to rotate, and the axial displacement of the movable frame 6 can be controlled by the reset gear 93 and the reset rack 94. The compression spring 83 can be compressed by the guide limiting part 82, and the rack limiting part 95 can limit the stroke of the reset rack 94 to ensure the stability of the reset operation.

[0033] The power-off triggered compression spring holding mechanism 10 includes an electromagnet mounting base 101 located at the end of the mounting frame 5 away from the clamp body 1 and away from the movable frame 6. An electromagnet 102 is mounted on the electromagnet mounting base 101. The electromagnet 102 cooperates with the movable frame 6 through a lever-type holding assembly 103 that keeps the compression spring 83 in a compressed state. The electromagnet mounting base 101 facilitates the fixation of the electromagnet 102 on the mounting frame 5. The electromagnet 102 can control the lever-type holding assembly 103 and control the contraction state of the compression spring 83 when it is energized. When the electromagnet 102 is energized, it controls the lever-type holding assembly 103 to apply resistance, ensuring that the compression spring 83 remains compressed. When the electromagnet 102 is de-energized, the resistance of the lever-type holding assembly 103 disappears, and the compression spring 83 extends. The compression spring 83 can drive the roller assembly 4 to brake quickly to a stop through the linkage mechanism 7.

[0034] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the lever-type retaining assembly 103 includes a retaining lever 1031 that is hinged in the middle to the end of the electromagnet mounting base 101 away from the mounting bracket 5 and is curved. One end of the retaining lever 1031 acts on the driving end 1021 of the electromagnet 102, and the other end is rotatably provided with a roller body 1032. The movable bracket 6 has a movable extension bracket 1033 extending to one side of the electromagnet mounting base 101. The movable extension bracket 1033 is fixedly connected to a movable plate 1034 located outside the electromagnet mounting base 101 and extending axially along the electromagnet mounting base 101. One end of the movable plate 1034 passes through the inner side of the electromagnet mounting base 101, and the other end of the movable plate 1034 has a direction away from the retaining lever. The bent portion 1035, which is bent at one end and abuts against the roller body 1032, can abut and limit the holding lever 1031 when the electromagnet 102 is energized. The roller body 1032 of the holding lever 1031 is located in the bent portion 1035 and can abut and limit the movable plate 1034. The movable frame 6 is connected to the movable plate 1034 through the movable extension frame 1033. The movable plate 1034 can drive the movable frame 6 to make axial displacement through the movable extension frame 1033. By limiting the movable plate 1034, the movable frame 6 can be limited, ensuring the compression state of the compression spring 83 and the retracted state of the roller assembly 4.

[0035] Among them, a safety clamp trigger detection switch assembly is provided between the movable extension frame 1033 and the mounting frame 5. The safety clamp trigger detection switch assembly is the micro switch in publication number CN 116513909 A, and the mounting clamp trigger detection switch assembly can detect the reset state of the brake roller 41, which is a prior art reference.

[0036] Specifically, the mounting bracket 5 is located on one side of the clamp body 1 in the horizontal direction, and the movable bracket 6 and the power-off triggered compression spring holding mechanism 10 are respectively located on both sides of the movable bracket 6 in the horizontal direction away from the mounting bracket 5. The linkage mechanism 7 includes a return lever 71 that is bent and hinged in the middle on the roller groove side plate 43. One end of the return lever 71 is hinged to the roller shaft 42, and the other end of the return lever 71 is hinged to one end of the first connecting rod 72. The other end of the first connecting rod 72 is hinged to the movable bracket 6. The movable bracket 6 can move the first connecting rod 72 by moving through the movable plate 1034, thereby controlling the braking state of the brake roller 41 through the return lever 71.

[0037] The principle of this embodiment is as follows: When the elevator is running normally, the electromagnet 102 is energized and limits the movable plate 1034 by holding lever 1031 and roller body 1032. At this time, the compression spring 83 is in a contracted state, and the brake roller 41 is contracted and set in the roller mounting groove 13. When the elevator is not running normally, the electromagnet 103 is de-energized and the drive end 1021 of the electromagnet 102 is contracted. The holding lever 1031 loses the limiting resistance on the movable plate 1034, and the compression spring 83 can drive the movable frame 6 to extend axially, thereby controlling the linkage mechanism 7 to drive the brake roller 41 to brake the guide rail 2. When the brake roller 41 needs to be reset after braking, the reset drive mechanism 9 can overcome the frictional resistance between the brake roller 41 and the guide rail 2, ensuring the reset effect of the brake roller 41. The compression spring 83 is contracted to the compressed state, and the electromagnet 102 is energized to continue to limit the movable plate 1034 by abutment, ensuring the compressed state of the compression spring 83 and reducing maintenance costs.

[0038] Example 2

[0039] This embodiment is basically the same as Embodiment 1 in structure and working principle, the difference being that, combined with Figure 5 , Figure 6 As shown, the mounting bracket 5 is located at one end of the clamp body 1 in the vertical direction and is arranged vertically with the clamp body 1. The movable bracket 6 and the power-off triggered compression spring holding mechanism 10 are respectively located on both sides of the end of the movable bracket 6 away from the mounting bracket 5 in the vertical direction and are located on both sides of the guide rail body 2. The linkage mechanism 7 includes a second link 73. One end of the second link 73 is hinged to the roller shaft 42 and the other end is hinged to the movable bracket 6. The movable bracket 6 can move by moving through the movable plate 1034, which can drive the second link 73 to move. The braking state of the brake roller 41 can be directly controlled by the second link 73, which is suitable for braking use environment and improves applicability.
