Description

Technical Field

[0001] This application relates to the field of manufacturing reset safety clamps, and in particular to electrically operated reset safety clamps. Background Technology

[0002] The electric reset safety clamp is a core safety protection device for elevators and other vertical lifting equipment. Its core function is to mechanically brake the car or counterweight to prevent accidents when the equipment experiences emergency malfunctions such as overspeeding or falling. At the same time, unlike traditional safety clamps that require manual intervention to reset, it can automatically complete the reset operation after braking through electric control, without disassembly or manual prying, thus improving the efficiency of equipment recovery.

[0003] Traditional safety brake structures have gradually revealed many technical limitations: some structures adopt rigid connection designs and lack flexible guidance and adjustment mechanisms. During braking, component misalignment can easily lead to inaccurate contact between the brake roller and the external guide rail, which not only reduces the effective transmission efficiency of braking friction but may also cause local stress concentration and aggravate component wear. Other structures, although equipped with guide components, are mostly single-directional guides, making it difficult to balance longitudinal movement stability and lateral position adjustment requirements. During braking, the overall force is uneven, which can easily lead to braking delay or reset jamming. In view of this, we propose an electric reset safety brake. Utility Model Content

[0004] The purpose of this invention is to provide an electric reset safety clamp to solve the problems mentioned in the background art.

[0005] The electrically operated reset safety clamp provided in this application adopts the following technical solution: including:

[0006] A mounting plate is provided, on one side of which a solenoid valve is fixedly mounted. A mounting block is provided below the solenoid valve. One side of the mounting block is slidably connected to one side of the mounting plate. The bottom end of the solenoid valve is fixedly connected to the top surface of the mounting block.

[0007] A first fixing block is disposed on the other side of the mounting block. One side of the first fixing block is fixedly connected to the other side of the mounting block. A connecting plate is fixedly installed on the top surface of the first fixing block. One side of the connecting plate is slidably connected to one side of the mounting plate.

[0008] An adjustment component is disposed on the mounting block.

[0009] Preferably, the adjustment assembly includes a brake roller, which is rotatably mounted inside the mounting block and located between the mounting block and the first fixed block. Limiting plates are provided above and below the brake roller, and one side of each of the two limiting plates is fixedly connected to the inner sidewall of the mounting block.

[0010] By adopting the above technical solution, when braking is required, the solenoid valve is energized and activated. Its bottom end drives the connected mounting block to slide longitudinally along the mounting plate. The mounting block simultaneously drives the first fixed block and the connecting plate to move. The solenoid valve, through the guide plate connected to the sliding plate, slides with the first guide block through the vertical guide groove, restricting the movement direction of the mounting block and preventing deviation. At the same time, the brake roller moves with the mounting block, and the second guide block at one end slides along the horizontal guide groove, so that the brake roller accurately contacts the external guide rail, generating braking friction. The pulley moves with the connecting plate to assist in adjusting the overall position and ensure balanced braking force. When the braking is released, the solenoid valve is de-energized, its driving force disappears, and the mounting block slides in the opposite direction along the mounting plate under the action of structural reset force, driving the first fixed block, the connecting plate and the adjustment components back to the initial position. The brake roller disengages from the external guide rail, and the pulley, guide plate and other components reset. The safety clamp returns to the ready-to-work state, completing one "brake-reset" cycle.

[0011] Preferably, the adjusting assembly further includes a sliding plate, which is disposed at the bottom end of the solenoid valve. The inner wall of the sliding plate is fixedly connected to the outer wall of the solenoid valve. A guide plate is fixedly installed on one side of the sliding plate. Two vertical guide grooves are formed on one side of the guide plate. A transverse guide groove is formed at the position corresponding to the guide plate of the brake roller. A first guide block is provided in each of the two vertical guide grooves. The outer walls of the two first guide blocks are slidably connected to the inner walls of the two vertical guide grooves. One end of each of the two first guide blocks is fixedly connected to one side of the mounting block. A second guide block is provided in the transverse guide groove. The outer wall of the second guide block is slidably connected to the inner wall of the transverse guide groove. One end of the second guide block is fixedly connected to one end of the brake roller.

[0012] By adopting the above technical solution, when braking is required, the solenoid valve is energized and activated. Its bottom end drives the connected mounting block to slide longitudinally along the mounting plate. The mounting block simultaneously drives the first fixed block and the connecting plate to move. The solenoid valve, through the guide plate connected to the sliding plate, slides with the first guide block through the vertical guide groove, restricting the movement direction of the mounting block and preventing deviation. At the same time, the brake roller moves with the mounting block, and the second guide block at one end slides along the horizontal guide groove, so that the brake roller accurately contacts the external guide rail, generating braking friction. The pulley moves with the connecting plate to assist in adjusting the overall position and ensure balanced braking force. When the braking is released, the solenoid valve is de-energized, its driving force disappears, and the mounting block slides in the opposite direction along the mounting plate under the action of structural reset force, driving the first fixed block, the connecting plate and the adjustment components back to the initial position. The brake roller disengages from the external guide rail, and the pulley, guide plate and other components reset. The safety clamp returns to the ready-to-work state, completing one "brake-reset" cycle.

[0013] Preferably, the other side of the sliding plate is fixedly connected to one side of the connecting plate.

[0014] By adopting the above technical solution, a stable connection between the sliding plate and the connecting plate is facilitated during use, ensuring the stability and reliability of the entire braking system during operation.

[0015] Preferably, a second fixing block is fixedly installed inside the connecting plate, and a mounting base is fixedly installed on the top surface of the second fixing block, with a pulley rotatably installed inside the mounting base.

[0016] By adopting the above technical solution, the pulley moves with the connecting plate, which helps to adjust the overall position and ensures balanced braking force.

[0017] Preferably, the mounting block and the outer wall of the first fixing block are fixedly mounted with the same connecting plate.

[0018] By adopting the above technical solutions, the stability and reliability of the entire braking system during operation are guaranteed.

[0019] Preferably, a guide groove is provided between the mounting block and the first fixing block.

[0020] By adopting the above technical solution, the mounting block can slide in the guide groove of the first fixed block during use. This design not only improves the reset accuracy of the braking system, but also ensures the smoothness of the braking process.

[0021] In summary, this application includes at least one of the following beneficial technical effects: the mounting block and the first fixed block maintain structural synchronization through a connecting plate; the guide groove between them provides a trajectory for subsequent movement; the pulley on the connecting plate is in an adjustable state; the brake roller is not in contact with the external guide rail; the overall component remains stable through the sliding connection between the mounting block, the connecting plate, and the mounting plate; when braking is required, the solenoid valve is energized and activated, its bottom end driving the connected mounting block to slide longitudinally along the mounting plate; the mounting block synchronously drives the first fixed block and the connecting plate to move; the solenoid valve, through the guide plate connected to the sliding plate, restricts the movement of the mounting block through the sliding engagement of the vertical guide groove with the first guide block. The direction is adjusted to avoid deviation. Simultaneously, the brake roller moves with the mounting block, and the second guide block at one end slides along the transverse guide groove, ensuring that the brake roller makes precise contact with the external guide rail, generating braking friction. The pulley moves with the connecting plate to assist in adjusting the overall position and ensure balanced braking force. When the braking release requirement is triggered, the solenoid valve is de-energized, its driving force disappears, and the mounting block slides in the opposite direction along the mounting plate under the action of structural reset force, driving the first fixed block, connecting plate, and adjustment components back to their initial positions. The brake roller disengages from the external guide rail, and the pulley, guide plate, and other components reset. The safety clamp returns to the ready-to-work state, completing one "brake-reset" cycle. Attached Figure Description

Detailed Implementation

[0027] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0028] This application discloses an electrically operated reset safety clamp.

[0029] Reference Figure 1 Electric reset safety clamp, including:

[0030] Mounting plate 1, with a solenoid valve 2 fixedly mounted on one side. A mounting block 3 is positioned below the solenoid valve 2, with one side of the mounting block 3 slidably connected to one side of the mounting plate 1. The bottom end of the solenoid valve 2 is fixedly connected to the top surface of the mounting block 3. The mounting block 3 slides longitudinally along the mounting plate 1, synchronously driving the first fixed block 9 and connecting plate 10 to move. The solenoid valve 2, connected to the guide plate 4 via the sliding plate 5, slides with the first guide block 7 via the vertical guide groove 6, restricting the movement direction of the mounting block 3 to prevent deviation. The first fixed block 9 is located on the other side of the mounting block 3, with one side of the first fixed block 9 fixedly connected to the other side of the mounting block 3. The top surface of the first fixed block 9 is fixedly mounted... A connecting plate 10 is provided, with one side of the connecting plate 1 slidably connected to one side of the mounting plate 1. Under the action of the structural reset force, the mounting block 3 slides in the opposite direction along the mounting plate 1, causing the first fixing block 9, the connecting plate 10, and the adjustment component to return to their initial positions. The brake roller 15 disengages from the external guide rail, and components such as the pulley 13 and the guide plate 4 are reset. The safety clamp returns to the ready-to-work state. The adjustment component is set on the mounting block 3. The brake roller 15 moves with the mounting block 3, and the second guide block 17 at one end slides along the transverse guide groove 8, so that the brake roller 15 accurately contacts the external guide rail, generating braking friction. The pulley 13 moves with the connecting plate 10 to assist in adjusting the overall position and ensure balanced braking force.

[0031] Reference Figure 2 The adjustment assembly includes a brake roller 15, which is rotatably mounted inside the mounting block 3 and located between the mounting block 3 and the first fixed block 9. Limiting plates 14 are provided above and below the brake roller 15, with one side of each limiting plate 14 fixedly connected to the inner wall of the mounting block 3. When braking is required, the solenoid valve 2 is energized, and its bottom end drives the connected mounting block 3 to slide longitudinally along the mounting plate 1. The mounting block 3 simultaneously drives the first fixed block 9 and the connecting plate 10 to move. The solenoid valve 2, connected to the guide plate 4 via the sliding plate 5, restricts the movement direction of the mounting block 3 through the sliding engagement of the vertical guide groove 6 with the first guide block 7, preventing deviation. Simultaneously, the brake roller... As the mounting block 3 moves, the second guide block 17 at one end slides along the transverse guide groove 8, making the brake roller 15 precisely contact the external guide rail to generate braking friction. The pulley 13 moves with the connecting plate 10 to assist in adjusting the overall position and ensure balanced braking force. When the braking release requirement is triggered, the solenoid valve 2 is de-energized, and its driving force disappears. Under the action of the structural reset force, the mounting block 3 slides in the opposite direction along the mounting plate 1, driving the first fixed block 9, the connecting plate 10, and the adjustment components back to their initial positions. The brake roller 15 disengages from the external guide rail, and the pulley 13, guide plate 4, and other components reset. The safety clamp returns to the ready-to-work state, completing one "brake-reset" cycle.

[0032] Reference Figure 3The adjustment assembly also includes a sliding plate 5, which is located at the bottom of the solenoid valve 2. The inner wall of the sliding plate 5 is fixedly connected to the outer wall of the solenoid valve 2. A guide plate 4 is fixedly installed on one side of the sliding plate 5. Two vertical guide grooves 6 are provided on one side of the guide plate 4. A transverse guide groove 8 is provided at the position corresponding to the guide plate 4 of the brake roller 15. A first guide block 7 is provided in each of the two vertical guide grooves 6. The outer walls of the two first guide blocks 7 are slidably connected to the inner walls of the two vertical guide grooves 6. One end of each of the two first guide blocks 7 is fixedly connected to one side of the mounting block 3. A second guide block 17 is provided in the transverse guide groove 8. The outer wall of the second guide block 17 is slidably connected to the inner wall of the transverse guide groove 8. One end of the second guide block 17 is fixedly connected to one end of the brake roller 15. When braking is required, the solenoid valve 2 is energized and activated. Its bottom end drives the connected mounting block 3 to slide longitudinally along the mounting plate 1. The first fixed block 9 and the connecting plate 10 move synchronously. The solenoid valve 2 is connected to the guide plate 4 through the sliding plate 5. The guide plate 4 slides with the first guide block 7 through the vertical guide groove 6, which restricts the movement direction of the mounting block 3 and prevents it from deviating. At the same time, the brake roller 15 moves with the mounting block 3. The second guide block 17 at one end slides along the horizontal guide groove 8, so that the brake roller 15 makes precise contact with the external guide rail and generates braking friction. The pulley 13 moves with the connecting plate 10 to help adjust the overall position and ensure balanced braking force. When the braking release is triggered, the solenoid valve 2 is de-energized and its driving force disappears. Under the action of the structural reset force, the mounting block 3 slides in the opposite direction along the mounting plate 1, which drives the first fixed block 9, the connecting plate 10 and the adjustment components to return to the initial position. The brake roller 15 disengages from the external guide rail, and the pulley 13, the guide plate 4 and other components reset. The safety clamp returns to the ready-to-work state and completes one "brake-reset" cycle.

[0033] Reference Figure 3 The other side of the sliding plate 5 is fixedly connected to one side of the connecting plate 10, which facilitates a stable connection between the sliding plate 5 and the connecting plate 10 during use, ensuring the stability and reliability of the entire braking system during operation.

[0034] Reference Figure 4 A second fixing block 11 is fixedly installed inside the connecting plate 10. A mounting base 12 is fixedly installed on the top surface of the second fixing block 11. A pulley 13 is rotatably installed inside the mounting base 12. The pulley 13 moves with the connecting plate 10 to assist in adjusting the overall position and ensure balanced braking force.

[0035] Reference Figure 4 The mounting block 3 and the outer wall of the first fixing block 9 are fixedly installed with the same connecting plate 16, which ensures the stability and reliability of the entire braking system during operation.

[0036] Reference Figure 2A guide groove is provided between the mounting block 3 and the first fixing block 9, which facilitates the sliding of the mounting block 3 in the guide groove of the first fixing block 9 during use. This design not only improves the reset accuracy of the braking system, but also ensures the stability during the braking process.

[0037] The implementation principle of the electric reset safety clamp in this embodiment is as follows: the mounting block 3 and the first fixed block 9 are kept structurally synchronized through the connecting plate 16. The guide groove between them provides a trajectory for subsequent movement. The pulley 13 on the connecting plate 10 is in an adjustable state. The brake roller 15 is not in contact with the external guide rail. The entire component is kept stable through the sliding connection between the mounting block 3, the connecting plate 10 and the mounting plate 1. When braking is required, the solenoid valve 2 is energized and activated. Its bottom end drives the connected mounting block 3 to slide longitudinally along the mounting plate 1. The mounting block 3 synchronously drives the first fixed block 9 and the connecting plate 10 to move. The solenoid valve 2 is connected to the guide plate 4 through the sliding plate 5. Through the vertical guide groove 6 and the sliding cooperation with the first guide block 7, the movement of the mounting block 3 is restricted. The direction of movement is adjusted to avoid deviation. At the same time, the brake roller 15 moves with the mounting block 3, and the second guide block 17 at one end slides along the transverse guide groove 8, so that the brake roller 15 makes precise contact with the external guide rail, generating braking friction. The pulley 13 moves with the connecting plate 10 to assist in adjusting the overall position and ensure balanced braking force. When the braking release requirement is triggered, the solenoid valve 2 is de-energized, and its driving force disappears. Under the action of the structural reset force, the mounting block 3 slides in the opposite direction along the mounting plate 1, driving the first fixed block 9, the connecting plate 10 and the adjustment components to return to the initial position. The brake roller 15 disengages from the external guide rail, and the pulley 13, the guide plate 4 and other components reset. The safety clamp returns to the ready-to-work state, completing one "brake-reset" cycle.
