Description

Technical Field

[0001] This utility model relates to the field of safety valve clamp technology, specifically a safety valve clamp protection device. Background Technology

[0002] Safety valves are critical safety protection devices for pressure vessels and pipeline systems. They automatically release pressure when the system pressure exceeds a set value to prevent explosions or equipment damage. Safety valve clamp protection devices use mechanical structures to firmly fix the safety valve, preventing it from moving or falling off during calibration or transportation. For example, the calibration bench interlocking safety protection device uses a two-stage cylinder to drive the protective plate to automatically rise and fall. It is linked with the pressure source to realize the function of raising the protective plate when the pressure is increased and lowering it after the pressure is reduced. It is suitable for safety valve calibration, transportation and installation.

[0003] Currently, most safety valve clamping devices use manual screw adjustment for clamping. When the size of the safety valve changes, a lot of time needs to be spent manually adjusting it, resulting in low adjustment efficiency. Furthermore, the clamping force is difficult to accurately match the different sizes of safety valves, leading to poor versatility. Utility Model Content

When the size of the safety valve changes, a lot of time needs to be spent manually adjusting it, resulting in low adjustment efficiency. Furthermore, the clamping force is difficult to accurately match the safety valves of different sizes, leading to poor versatility.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This safety valve clamping and protection device uses a servo motor as its power source. The output of the servo motor drives the worm gear to rotate, and the worm gear drives the worm wheel to rotate through meshing transmission. The worm wheel synchronously drives the gear plate to rotate. The gear plate meshes with two rack supports, converting the rotational motion into the linear reverse motion of the two rack supports.

The positioning plate is rigidly connected to the fixed seat through a connecting bolt. The connecting bolt firmly fixes the positioning plate in the preset position of the fixed seat, so that the position of the positioning plate can be adjusted as the fixed seat moves, thereby achieving the effect of lateral positioning support for the safety valve and facilitating positioning and guidance.

The worm wheel 9 synchronously drives the gear plate 10 to rotate. The gear plate 10 meshes with the two rack frames 11, converting the rotational motion into the linear reverse motion of the two rack frames 11, thereby driving the clamping parts 12 on the rack frames 11 to achieve synchronous opening and closing actions.

[0019] Specifically, two rack frames 11 are respectively disposed on both sides of the gear disk 10 and mesh with the gear disk 10. When the gear disk 10 is driven to rotate by the worm gear 9, the reverse transmission characteristics of gear meshing are used to drive the rack frames 11 on both sides to move in a straight line in opposite directions. At the same time, the rack frames 11 are rigidly connected to the clamp 12 through the fixing bolt 13, so as to accurately transmit the linear motion of the rack frames 11 to the clamp 12, thereby realizing the synchronous opening and closing action of the clamp 12.

The worm wheel 9 synchronously drives the gear plate 10 to rotate. The gear plate 10 meshes with the two rack frames 11, converting the rotational motion into the linear reverse motion of the two rack frames 11, thereby driving the clamping parts 12 on the rack frames 11 to achieve synchronous opening and closing actions. At the same time, the electric telescopic arm 4 can adjust the overall position of the first mounting frame 5 and the second mounting frame 6 by telescopic adjustment to adapt to the clamping requirements of the safety valve under different working conditions. Compared with related technologies, the safety valve clamping protection device provided by this utility model has the following beneficial effects: thereby achieving the effect of facilitating accurate matching of safety valves of different sizes and improving versatility.

[0021] Example 2: Please refer to Figures 1-4. A double-headed screw frame 14 is fixedly installed on the outer surface of the base 1. A fixed seat 15 is provided on the outer surface of the double-headed screw frame 14. A positioning plate 16 is provided on the outer surface of the fixed seat 15. A connecting bolt 17 is provided on the outer surface of the fixed seat 15. The fixed seat 15 is fixedly connected to the positioning plate 16 through the connecting bolt 17.

[0022] Specifically, the double-headed lead screw frame 14 provides a guide and drive foundation for the fixed seat 15. The rotation of the lead screw can drive the two fixed seats 15 to move synchronously in opposite directions or in the same direction along the axis of the lead screw. The positioning plate 16 is rigidly connected to the fixed seat 15 through the connecting bolt 17. The connecting bolt 17 firmly fixes the positioning plate 16 in the preset position of the fixed seat 15, so that the position of the positioning plate 16 can be adjusted as the fixed seat 15 moves, thereby achieving the effect of forming a lateral positioning support for the safety valve and facilitating positioning and guidance.

[0023] In the embodiment: pressure sensors are provided inside both the clamp 12 and the positioning plate 16, and anti-slip pads are provided on the outer surfaces of both the clamp 12 and the positioning plate 16.

[0024] Specifically, the pressure sensors inside the clamping member 12 and the positioning plate 16 collect pressure data in real time during the clamping process, and realize dynamic monitoring of the clamping force through signal feedback; the anti-slip pads on the outer surface of the clamping member 12 and the positioning plate 16 utilize their surface textures such as anti-slip patterns and high friction coefficient materials such as rubber or silicone to increase the contact friction with the safety valve body and reduce the relative sliding tendency.

[0025] In the embodiment: the lead screw frame 2 is made of a frame, lead screw, motor and slide, the double-headed lead screw frame 14 is made of a double-headed motor, frame, two lead screws and two slides, and a controller is provided on the outer surface of the base 1. The controller is electrically connected to the servo motor 7, drive motor, motor, double-headed motor, electric telescopic arm 4 and pressure sensor.

[0026] Specifically, the lead screw frame 2 is driven by a motor to rotate the lead screw, converting the rotational motion of the motor into linear motion of the sliding parts along the frame, thereby adjusting the position of the clamping part 12 support structure. The double-headed lead screw frame 14 is driven by a double-headed motor to rotate two lead screws synchronously, causing two sliding parts to move synchronously in the same or opposite directions along the frame, thereby adjusting the symmetrical position of the positioning plate 16. The controller, as the core control unit, receives the clamping force signal from the pressure sensor in real time through electrical connection, and sends control commands to the servo motor 7, drive motor, double-headed motor and electric telescopic arm 4. It accurately adjusts the motion parameters of each component according to the preset program or sensor feedback data, forming a closed-loop control process of perception, decision-making and execution. The controller is an existing structure, and the control circuit can be implemented by those skilled in the art through simple programming. It is common knowledge in the field and is only used without modification. Therefore, the control method and circuit connection will not be described in detail, so as to facilitate centralized control operation of the relevant structures.

[0027] In the embodiment: the base 1 and the lead screw frame 2 are set at an angle of 90 degrees, the first mounting frame 5 and the second mounting frame 6 are set at an angle of 90 degrees, and the two positioning plates 16 are set opposite each other.

[0028] Specifically, the base 1 and the lead screw frame 2 are set at a 90-degree angle to form a three-dimensional support structure. The overall force is distributed through the spatial orthogonal layout of the device, while providing an independent working dimension perpendicular to the plane of the base 1 for the linear movement of the lead screw frame 2. The first mounting bracket 5 and the second mounting bracket 6 are set at a 90-degree angle to construct a multi-directional clamping and covering system, so that the two sets of clamps 12 respectively form cross constraints on the safety valve in the vertical direction. The two positioning plates 16 are set opposite each other, and form lateral positioning constraints through symmetrical distribution. The reverse force is used to counteract the lateral offset force during the clamping process of the safety valve. The three components achieve force balance and spatial adaptation through the coordinated design of angle and orientation.

[0029] Working principle: A double-ended lead screw frame 14 is fixedly installed on the outer surface of the base 1. A fixed seat 15 is provided on the outer surface of the double-ended lead screw frame 14, and a positioning plate 16 is provided on the outer surface of the fixed seat 15. A connecting bolt 17 is also provided on the outer surface of the fixed seat 15. The fixed seat 15 is fixedly connected to the positioning plate 16 via the connecting bolt 17. The double-ended lead screw frame 14 provides guidance and a driving foundation for the fixed seat 15. The rotation of the lead screw drives the two fixed seats 15 to move synchronously in opposite directions or in the same direction along the lead screw axis. The positioning plate 16 is rigidly connected to the fixed seat 15 via the connecting bolt 17, which firmly fixes the positioning plate 16 in a preset position on the fixed seat 15. This allows the positioning plate 16 to adjust its position as the fixed seat 15 moves. The double-ended lead screw frame 14 drives the fixed seat 15 to move synchronously, ensuring that the two positioning plates 16 are aligned. The symmetrical and uniform positioning support of the entire valve avoids uneven force distribution caused by unilateral positioning offset, thus improving overall positioning stability. The rigid fixing structure of the connecting bolt 17 ensures a stable assembly between the positioning plate 16 and the fixed seat 15, preventing the positioning plate 16 from loosening or shifting under clamping or vibration conditions, ensuring positioning accuracy, and reducing the risk of damage to the safety valve due to positioning deviation. The detachable connecting bolt 17 design facilitates quick replacement of positioning plates 16 of different specifications according to the external dimensions of the safety valve, without the need to adjust the core structure of the double-headed screw frame 14, enhancing the device's adaptability to different models of safety valves, improving maintenance convenience and equipment versatility. Compared with related technologies, the safety valve clamp protection device provided by this utility model has the following beneficial effects: it achieves the effect of forming lateral positioning support for the safety valve, facilitating positioning guidance.
