Description

Technical Field

[0001] This utility model relates to the field of fire protection facility maintenance equipment technology, and in particular to a stable telescopic disassembly device for smoke and temperature sensors. Background Technology

[0002] Smoke and temperature sensors are devices used to monitor changes in smoke and temperature, and are commonly used in fire alarm systems. They combine smoke and temperature sensing functions, enabling them to issue timely alerts by detecting smoke concentration and temperature increases in the early stages of a fire. To allow users or professionals to easily remove smoke and temperature sensors during maintenance, inspection, or replacement without causing other safety hazards, a stable, telescopic removal device for smoke and temperature sensors is required.

[0003] A search revealed Chinese Patent Publication No. CN203818070U, which discloses a device for disassembling and assembling smoke detectors and temperature detectors. The device includes a fixing component and a supporting component, with the supporting component connected to the fixing component. The fixing component includes a core and a base. One end of the base is connected to the supporting component, and the base has a protruding component. The base can mount protective covers for the smoke detector and temperature detector, while the protruding component allows for the removal of the protective covers. One end of the core is connected to the base, and the other end of the core can be engaged with the probes of the smoke detector and temperature detector. This device for disassembling and assembling smoke detectors and temperature detectors is simple in structure, easy to operate, and equipped with a lighting device, facilitating operation in various dimly lit environments. It not only improves the speed of disassembling and assembling smoke detectors and temperature detectors and reduces the labor intensity of workers, but also enhances worker safety.

[0004] However, in actual use, the structure of the above-mentioned device is difficult to guarantee stability under different operating conditions. During disassembly, shaking or tilting can easily cause the connection between the smoke temperature sensor and the installation part to become loose or abnormal.

[0005] The device is not stable or reliable enough, which increases maintenance costs and safety hazards. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a stable telescopic disassembly device for smoke temperature sensors, which aims to improve the problem that the connection between the smoke temperature sensor and the installation part is easily loosened and abnormal due to shaking, tilting, etc. during the disassembly process, resulting in the device being unstable and unreliable.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a stable telescopic disassembly device for a smoke temperature sensor, comprising a base plate, a motor I fixedly connected inside the base plate, a lead screw fixedly mounted at the output end of the motor I, a bracket rotatably connected to the outer wall of the lead screw, a sleeve I fixedly connected to the outer wall of the bracket, the lower surface of the sleeve I fixedly connected to the upper surface of the base plate, a sleeve II slidably connected inside the sleeve I, the inner surface of the sleeve II slidably connected to the outer wall of the bracket, a slider threadedly connected to the outer wall of the lead screw, the outer wall of the slider fixedly connected to the inner surface of the sleeve II, a motor II fixedly connected inside the slider, a roller fixedly mounted at the output end of the motor II, a belt mounted on the outer wall of the roller, a push block fixedly connected to the outer wall of the belt, a vertical plate fixedly connected to the outer wall of the push block, the outer wall of the vertical plate slidably connected to the inner surface of the sleeve II, and a connecting assembly mounted on the upper surface of the vertical plate.

[0008] The above technical solution provides the following: motor one drives the lead screw to rotate, which in turn drives the slider to move stably. The slider then drives sleeve two to extend and retract inside sleeve one. Simultaneously, starting motor two provides power to rotate the roller, which in turn drives the belt to transmit power. The pusher on the outer wall of the belt drives the vertical plate to extend and retract inside sleeve two, thereby achieving a stable extension and retraction of the device. This more effectively adapts to the disassembly and installation of the smoke temperature sensor under different conditions.

[0009] As a further description of the above technical solution:

[0010] The connecting assembly includes a fixing plate, the lower surface of which is fixedly connected to the upper surface of the upright plate. A motor is fixedly connected to the outer wall of the fixing plate. A bidirectional threaded rod is fixedly provided at the output end of the motor. The outer wall of the bidirectional threaded rod is rotatably connected to the inside of the fixing plate. A sliding plate is threadedly connected to the outer wall of the bidirectional threaded rod. A spring is provided on the outer wall of the sliding plate. An elastic protective sleeve is provided on the outer wall of the spring.

[0011] Through the above technical solution: when the motor is started, it can drive the bidirectional threaded rod to rotate, and the rotation of the bidirectional threaded rod can drive the sliding plate to move. The spring and elastic protective sleeve set on the outer wall of the sliding plate can protect the connection of the smoke temperature sensor. When vibrating or moving, the spring can absorb energy and reduce the impact on the smoke temperature sensor.

[0012] As a further description of the above technical solution:

[0013] A hydraulic cylinder is fixedly connected to the outer wall of the upright plate, and a connecting frame is fixedly installed at the output end of the hydraulic cylinder.

[0014] The above technical solution allows the upright plate to support the hydraulic rod, and the hydraulic cylinder can be activated to drive the connecting frame to move.

[0015] As a further description of the above technical solution:

[0016] The connecting frame is fixedly connected to a sliding shaft inside, and a fixing block is slidably connected to the outer wall of the sliding shaft. The outer wall of the fixing block is fixedly connected to the outer wall of the upright plate.

[0017] The above technical solution allows the connecting frame to drive the sliding shaft to move, with the sliding shaft acting as a limit switch. The movement of the sliding shaft can cause the rotating block to flip.

[0018] As a further description of the above technical solution:

[0019] A rotating block is slidably connected to the outer wall of the sliding shaft, and a protective cover is fixedly connected to the outer wall of the rotating block.

[0020] Through the above technical solution: the rotation of the rotating block can drive the protective cover to unfold and fold. The protective cover is made of transparent high-strength plastic. When the protective cover is unfolded, it covers the smoke and temperature sensor and surrounding facilities. The protective cover can prevent the tools or disassembly device itself from accidentally touching the surrounding facilities during the disassembly process, and at the same time, it can also collect parts that may fall off during the disassembly process.

[0021] As a further description of the above technical solution:

[0022] The rotating block is rotatably connected to a fixed shaft, and the outer wall of the fixed shaft is fixedly connected to the inside of the fixed block.

[0023] The above technical solution allows the rotating block to rotate on the outer wall of the fixed shaft, and the fixed block can support the rotating block by fixing the fixed shaft.

[0024] As a further description of the above technical solution:

[0025] The outer wall of the sleeve is provided with a plurality of reinforcing ribs, and the lower surface of the reinforcing ribs is fixedly connected to the upper surface of the base plate.

[0026] The above technical solution can enhance the strength and rigidity of the sleeve by setting multiple reinforcing ribs on the outer wall of the sleeve. The reinforcing ribs are triangularly distributed inside and outside the telescopic arm, thereby improving the stability of the device.

[0027] As a further description of the above technical solution:

[0028] A support leg is fixedly connected to the lower surface of the base plate, a support surface is fixedly connected to the lower surface of the support leg, a hydraulic rod is fixedly connected to the upper surface of the support surface, and the output end of the hydraulic rod is fixedly connected to the lower surface of the base plate.

[0029] Through the above technical solution, the support legs can be extended and retracted to stabilize and adjust the height of the base plate, and the extension and retraction of the hydraulic rod can drive the base plate to move stably, so as to adapt to the installation and removal of the smoke and temperature sensor under different conditions.

[0030] This utility model has the following beneficial effects:

[0031] 1. In this utility model, starting motor one drives the lead screw to rotate, which in turn drives sleeve two to slide inside sleeve one. Starting motor two drives the roller to rotate, which in turn drives the push block to move, and at the same time drives the upright plate to slide inside sleeve two. The multiple reinforcing ribs can play the role of stabilizing the adjustment and telescopic device, thereby improving the stability and reliability of the device.

[0032] 2. In this utility model, the hydraulic cylinder is activated to move the connecting frame, which in turn causes the sliding shaft to slide. At the same time, the rotating block rotates on the outer wall of the fixed shaft, which in turn causes the protective cover to flip over. This provides all-round protection for the surrounding facilities, avoids accidental contact and damage caused by falling parts during disassembly, and reduces the safety risks during maintenance.

[0043] Specifically, base plate 1 fixes motor 2. Starting motor 2 drives lead screw 3 to rotate. Motor 2 drives the rotation of lead screw 3.

This can be adjusted according to different installation environments to allow for disassembly of the smoke temperature sensor under different conditions.

[0044] Reference Figure 6 The connecting assembly 14 includes a fixing plate 1401, the lower surface of the fixing plate 1401 is fixedly connected to the upper surface of the upright plate 13, a motor 1402 is fixedly connected to the outer wall of the fixing plate 1401, a bidirectional threaded rod 1403 is fixedly provided at the output end of the motor 1402, the outer wall of the bidirectional threaded rod 1403 is rotatably connected to the inside of the fixing plate 1401, a sliding plate 1404 is threadedly connected to the outer wall of the bidirectional threaded rod 1403, a spring 1405 is provided on the outer wall of the sliding plate 1404, and an elastic protective sleeve 1406 is provided on the outer wall of the spring 1405.

[0045] Specifically, the upright plate 13 fixes the fixed plate 1401, and the fixed plate 1401 fixes the motor 1402. By starting the motor 1402, the bidirectional threaded rod 1403 is driven to rotate inside the fixed plate 1401.

[0046] Reference Figure 4 and Figure 5A hydraulic cylinder 15 is fixedly connected to the outer wall of the upright plate 13. A connecting frame 16 is fixedly installed at the output end of the hydraulic cylinder 15. A sliding shaft 17 is fixedly connected inside the connecting frame 16. A fixing block 18 is slidably connected to the outer wall of the sliding shaft 17. The outer wall of the fixing block 18 is fixedly connected to the outer wall of the upright plate 13. A rotating block 20 is slidably connected to the outer wall of the sliding shaft 17. A protective cover 21 is fixedly connected to the outer wall of the rotating block 20. A fixing shaft 19 is rotatably connected inside the rotating block 20. The outer wall of the fixing shaft 19 is fixedly connected to the inside of the fixing block 18.

[0047] Specifically, the upright plate 13 fixes the hydraulic cylinder 15. Activating the hydraulic cylinder 15 moves the connecting frame 16, which in turn moves the sliding shaft 17 within the fixed block 18. The fixed block 18 has a limiting groove to limit the sliding shaft 17. The sliding shaft 17 slides within the rotating block 20, which has a limiting groove to limit the sliding shaft 17. The sliding shaft 17 drives the rotating block 20 to rotate on the outer wall of the fixed shaft 19. The fixed shaft 19 fixes the fixed block 18. The rotating block 20 causes the protective cover 21 to flip. The protective cover 21 is made of transparent, high-strength plastic. When disassembling the smoke and temperature sensor, the protective cover 21 is unfolded and covers the smoke and temperature sensor and surrounding facilities. The protective cover 21 prevents accidental contact between tools or disassembly devices and surrounding facilities during disassembly, and also collects any parts that may fall during disassembly, preventing damage to surrounding facilities.

[0048] Reference Figure 1 The outer wall of sleeve 5 is provided with multiple reinforcing ribs 4, and the lower surface of the reinforcing ribs 4 is fixedly connected to the upper surface of the base plate 1.

[0049] Specifically, by setting multiple reinforcing ribs 4 on the outer wall of sleeve 5, the device can be stabilized. The reinforcing ribs 4 are distributed in a triangular pattern inside and outside the telescopic arm, which enhances the strength and rigidity of the telescopic arm and greatly improves the stability and reliability of the telescopic dismantling device in various environments.

[0050] Reference Figure 1 A support leg 22 is fixedly connected to the lower surface of the base plate 1, a support surface 23 is fixedly connected to the lower surface of the support leg 22, a hydraulic rod 24 is fixedly connected to the upper surface of the support surface 23, and the output end of the hydraulic rod 24 is fixedly connected to the lower surface of the base plate 1.

[0051] Specifically, the base plate 1 fixes the support leg 22, which can extend and retract. The support leg 22 fixes the support surface 23, which in turn fixes the hydraulic rod 24. By activating the hydraulic rod 24, the base plate 1 is moved, thereby achieving a stable adjustment of the support leg 22 to adapt to different installation environments.

[0052] Working Principle: When using this disassembly device, the height of the base plate 1 is first adjusted according to different installation environments. The hydraulic rod 24 is activated to extend and retract the support leg 22, thus adjusting the position of the base plate 1. When the length of the telescopic arm needs adjustment, the motor 2 drives the lead screw 3 to rotate inside the bracket 6. Simultaneously, the lead screw 3 rotates, causing the slider 8 to slide, which in turn causes the sleeve 7 to slide inside the sleeve 5. At the same time, the motor 9 drives the roller 10 to rotate, which in turn drives the belt 11. While the belt 11 is working, the push block 12 moves, simultaneously causing the upright plate 13 to slide inside the sleeve 7. This allows for flexible adjustment of the telescopic arm's length to accommodate different installation distances. Multiple reinforcing ribs 4 are provided on the inner and outer walls of the sleeve 5 and the upright plate 13 to enhance structural stability. When the upright plate 13 needs to be unfolded, the hydraulic cylinder 15 is activated to move the connecting frame 16. While moving, the sliding shaft 17 slides inside the fixed block 18. Simultaneously, the sliding shaft 17 slides inside the rotating block 20, causing the rotating block 20 to rotate on the outer wall of the fixed shaft 19. This, in turn, causes the protective cover 21 to flip, facilitating its unfolding and folding. The protective cover 21 prevents accidental contact with surrounding facilities by tools or the disassembly device itself during disassembly. It also collects any parts that may fall during disassembly, preventing damage to surrounding facilities. This device not only allows for flexible and stable adjustment of the telescopic arm, improving its stability and reliability in various environments, but also ensures that the device does not shake or shift during operation, whether on flat ground or in complex installation environments. It provides a stable operating platform for the safe disassembly of the smoke and temperature sensor and effectively protects the smoke and temperature sensor from impact and damage during disassembly, extending its service life.
