Description

Technical Field

[0001] This utility model relates to the field of fire slide technology, and in particular to a telescopic fire emergency slide that can be intelligently controlled. Background Technology

[0002] In the field of fire emergency response, emergency slides are crucial escape equipment, and their safety, stability, and reliability directly impact personnel safety. Traditional fire emergency slides often suffer from several problems during use: some slides' angle adjustment mechanisms lack effective self-locking functions, making them prone to uneven force distribution or external forces causing them to reset after being raised, potentially leading to falls and injuries to those sliding; if sliding components lack precise limiting structures during movement, they are prone to misalignment and lifting, accelerating wear between components and shortening the equipment's lifespan; if the slide's telescopic drive mechanism cannot be stably controlled, it may cause rapid movement of telescopic components, leading to collisions and damage, or even drive component breakage, affecting the normal use of the escape route; insufficient precision in angle adjustment makes it difficult to accurately adjust the slide's slope according to actual needs, causing inconvenience to escapees; among these issues, the lack of a reliable self-locking function in the angle adjustment mechanism of traditional emergency slides makes them susceptible to accidental reset due to external forces or their own weight after being raised. This problem directly threatens the safety of escapees and has become a key bottleneck restricting the improvement of emergency slide safety performance. Therefore, these problems need to be addressed. Utility Model Content

The system includes a hinged main slide 5, which facilitates the installation of a limiting rod 6 and an auxiliary slide 7. The auxiliary slide 7 is slidably installed within the main slide 5, allowing for the extension of the main slide 5. An intelligent control component is installed on the upper part of the base 1. A limiting rod 6 is installed below the top of the main slide 5, allowing for the limiting of the steel wire 14. Hinge blocks 9 are installed at both the front and rear ends of the main slide 5, facilitating the subsequent installation of the connecting plate 22. A connecting block 8 is installed at the bottom of the auxiliary slide 7, allowing for the connection of the steel wire. 14; The intelligent control component includes a first motor 10 and a fixed platform 11 fixed on the other side above the base 1. The first motor 10 facilitates the driving of the reducer 12. The fixed platform 11 facilitates the installation of the rotating rod 13 and the speed sensor 24. The front end of the fixed platform 11 is at the same end as the driving end of the first motor 10, and the fixed platform 11 is located at the rear end of the first motor 10. The reducer 12 is installed on the outside of the driving end of the first motor 10 through a coupling. The reducer 12 facilitates the transmission of the reduced driving force of the first motor 10 to the rotating rod. Rod 13; A rotating rod 13 is sleeved on the outer side of the other end of the reducer 12, which facilitates the winding of the steel wire 14; The rotating rod 13 passes through the front and rear ends of the fixed platform 11, and the outer side of the rotating rod 13 is wrapped with steel wire 14, which facilitates the cooperation with the limit rod 6 and the telescopic slide 7; A speed sensor 24 is installed on the rear end face of the fixed platform 11, and the detection end of the speed sensor 24 is coaxial with the rotating rod 13, which facilitates the detection of the rotation speed of the rotating rod 13. The speed sensor 24 is model FJ18.

[0021] In this utility model, a drive platform 15 is installed on one side of the fixed platform 11, which facilitates the installation of the sliding platform 21. Sliding grooves 16 are respectively provided at the front and rear ends of the inner cavity of the drive platform 15, which facilitates limiting the sliding position of the sliding platform 21. A second motor 17 is installed between the fixed platform 11 and the drive platform 15, which facilitates providing driving force to the worm gear 18. The drive end of the second motor 17 is fixedly connected to the worm gear 18, which facilitates driving the worm wheel 19. A lead screw 20 is horizontally installed in the inner cavity of the drive platform 15, which facilitates driving the sliding platform 21. One end of the lead screw 20 is installed at one end of the inner cavity of the drive platform 15, and the other end of the lead screw 20 passes through the other end of the drive platform 15. The other end of the lead screw 20 is fixedly connected to the worm wheel 19, which facilitates transmitting the driving force of the second motor 17 to the lead screw 20. The worm wheel 19 meshes with the worm gear 18 for transmission. A sliding platform 21 is threadedly connected to the outside of the rod 20, which facilitates the installation of the connecting plate 22. A laser sensor 23 is installed on the other side of the inner cavity of the drive platform 15, which facilitates the detection of the sliding displacement of the sliding platform 21. The laser sensor 23 is model L261. The detection end of the laser sensor 23 points to the other side of the sliding platform 21. The front and rear ends of the sliding platform 21 are limited by the sliding grooves 16 opened in the drive platform 15, and the front and rear ends of the sliding platform 21 are hinged to the connecting plate 22, which facilitates the lifting and lowering of the main slide 5 through the sliding platform 21. The other end of the steel wire 14 in the intelligent control component passes around the limiting rod 6 installed at the top of the main slide 5, and the steel wire 14 is connected to the connecting block 8 installed at the bottom of the auxiliary slide 7. The bottom end of the drive platform 15 is fixed to the top surface of the other side of the support plate 3, and the other end of the connecting plate 22 is hinged to the hinge block 9 installed on the main slide 5.

[0022] Working principle: When using this utility model, the equipment is powered on. After the universal wheels 2 installed at the bottom of the base 1 are pushed to the position to be practiced, the universal wheels 2 are self-locked to fix the base 1. The second motor 17 is started, which drives the worm gear 18 to rotate. The rotation of the worm gear 18 drives the worm wheel 19 to rotate. Since the worm wheel 19 is connected to the lead screw 20, the rotation of the worm wheel 19 will drive the lead screw 20 to rotate, thereby driving the sliding table 21, which is threadedly connected to the lead screw 20, to slide within the drive table 15. The sliding table 21 will then slide through the hinge table 4 and the support... The main slide 5, hinged to the support plate 3, is raised. The laser sensor 23, installed on the other side of the inner cavity of the drive platform 15, detects the displacement distance of the sliding platform 21 (thus calculating the lifting angle of the main slide 5). Since the front and rear ends of the sliding platform 21 are limited by the sliding grooves 16 opened in the drive platform 15, when the connecting plate 22, which is hinged to the drive platform 15, pushes the main slide 5, which is hinged to the other end of the connecting plate 22 through the hinge block 9, to lift, the sliding platform 21 will not be lifted, thus preventing wear between the lead screw 20 and the sliding platform 21. Due to the worm gear... The self-locking main slide 5 of worm gear 19 and worm 18 will not release force to reset the main slide 5, thus preventing injury. After the main slide 5 is stable, the first motor 10 is started, and the driving force is transmitted to the rotating rod 13 through the reduction gear 12. The rotating rod 13 will retract and extend the steel wire 14 sleeved on the outside of the rotating rod 13. Since the steel wire 14 is limited by the limiting rod 6 installed below the top of the main slide 5 and connected to the connecting block 8 at the lower end of the auxiliary slide 7, when the steel wire 14 retracts and extends the auxiliary slide 7 relative to the main slide 5, it can prevent injury. The main slide 5 is worn (to extend the service life of the main slide 5). The speed sensor 24 installed at the rear end of the fixed platform 11 will detect the rotation speed of the rotating rod 13 (to prevent damage to the reducer 12 when detecting the rotation speed of the rotating rod 13, and to avoid the situation where the rotation speed of the rotating rod 13 is too fast, causing the steel wire 14 to retract quickly and causing damage to the main slide 5 when the auxiliary slide 7 extends, and also to prevent the steel wire 14 from being directly damaged under over-tension). When it is necessary to retract, the first motor 10 and the second motor 17 can be reversed.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
