Description

Technical Field

[0001] The invention relates to the technical field of underground rescue tools, and in particular to an anti-falling underground rescue device. Background Art

[0002] In underground rescue operations, rescuers need to rely on professional equipment for descent and operation. Traditional rescue equipment often has a single function and cannot meet the needs of complex and changing rescue environments. Especially when urgently treating the rescued, rescuers need to quickly access first aid equipment, but traditional equipment often lacks a convenient first aid equipment storage and quick access mechanism. In addition, once the equipment fails or the rescuer makes an operational error, the rescue equipment may fall quickly, posing a great safety hazard to the rescue operation.

[0003] In view of the above problems, the market urgently needs an underground rescue device that can stably control the descent speed, provide first aid equipment in emergency situations, and have an anti-fall function. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the rescue equipment in the prior art often has a single function and cannot meet the needs of complex and changeable rescue environments. Especially when treating the rescued person in an emergency, the rescuers need to quickly access first aid equipment, but traditional equipment often lacks a convenient first aid equipment storage and quick access mechanism. In addition, once the equipment fails or the rescuer makes an operational error, the rescue equipment may fall quickly, posing a great safety hazard to the rescue operation, and an anti-fall underground rescue device is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An anti-fall underground rescue device comprises a device housing and a safety rope, wherein the device housing is sleeved on the outer wall of the safety rope, a seat plate is fixedly connected to the bottom of one side of the device housing, two symmetrically arranged storage boxes for placing first aid tools are slidably penetrated through one side of the device housing, and a brake assembly for braking the storage box is arranged at the middle position of the top of the seat plate;

[0007] A fixing plate is fixedly connected to the inner wall of the device housing, a counterweight is fixedly connected to one side of the top of the fixing plate, and a control component for controlling the downward movement of the device is provided on one side of the counterweight;

[0008] Anti-falling components for preventing the device housing from falling are arranged on both sides of the device housing.

[0009] In a possible design, the brake assembly includes a rectangular groove opened on one side of the top of the seat plate, a sliding plate slidingly penetrates the interior of the rectangular groove, a rectangular hole is opened on one side of the device housing, a connecting block is fixedly connected to one side of the sliding plate, the connecting block is slidably connected to the interior of the rectangular hole, and a tension spring is fixedly connected between the top of the connecting block and the top inner wall of the rectangular hole.

[0010] In a possible design, one side of the storage box is fixedly connected to a side block, one side of the connection block is fixedly connected to a cross plate, both sides of the bottom of the cross plate are fixedly connected to positioning rods, and a positioning groove is opened in the middle position of the side block, and the positioning groove is engaged with the positioning rod.

[0011] In one possible design, the control component includes two rotating shafts symmetrically arranged and rotatably connected to one side of the counterweight block, and the outer wall fixed sleeve of the rotating shaft is provided with a friction roller. The two friction rollers are respectively located on both sides of the safety rope and are used in conjunction with the safety rope. A servo motor is fixedly connected to the inner wall of one side of the device housing, and the output shaft of the servo motor is fixedly connected to one end of one of the rotating shafts.

[0012] In a possible design, a same support plate is slidably connected between the inner walls on both sides of the device housing, two symmetrically arranged first springs are fixedly connected between the bottom of the support plate and the top of the fixed plate, two centrally symmetrical racks are slidably connected to the top of the support plate, a gear is fixedly sleeved on the outer wall of the rotating shaft, the two gears are meshed and staggered, the two gears are respectively meshed with two racks, and one end of the rack is fixedly connected to an L-shaped push plate.

[0013] In a possible design, the anti-fall assembly includes two symmetrically arranged round rods that slide through one side of the device housing, one end of the round rod is fixedly connected to a limiting block, a second spring is fixedly connected between one side of the limiting block and an inner wall of one side of the device housing, the second spring is sleeved on the round rod, the other ends of the two round rods are fixedly connected to the same side plate, and a plurality of fixed tips are provided on one side of the side plate.

[0014] In a possible design, strip holes are provided on both sides of the device housing, and the L-shaped push plate is used in conjunction with the strip holes. The L-shaped push plate is used to push the side plate to move laterally, and a rectangular block is fixedly connected to one side of one of the L-shaped push plates. An elastic switch electrically connected to the servo motor is provided on the inner wall of one side of the device housing, and the rectangular block is used in conjunction with the elastic switch.

[0015] In a possible design, two symmetrically arranged reinforcing plates are fixedly connected between the bottom of the seat and one side of the device housing, a first elastic strap is arranged on the top of the seat, and two symmetrically arranged second elastic straps are arranged on one side of the device housing.

[0016] In the present application, when in use, the rescuer sits on the seat board, and the device housing is entirely attached to the safety rope. Due to the friction between the friction roller and the safety rope, the device housing cannot be directly moved down. The servo motor is started, and the output shaft of the servo motor drives one of the rotating shafts to rotate. The rotating shaft drives the other rotating shaft to rotate through the gear. At this time, the two rotating shafts drive the two friction rollers to rotate, and the friction rollers rotate, and the device housing slowly moves down along the side block.

[0017] The rescuer can gradually move down to the bottom of the well. At this time, if emergency treatment is needed for the rescued person, the rescuer can move away from the top of the seat plate, and then the sliding plate is under no pressure. The connecting block moves up under the tension of the tension spring, and the connecting block drives the sliding plate to move up. The connecting block also drives the internal cross plate to move up, and the cross plate drives the positioning rod to move up. The positioning rod moves out of the positioning groove, and the braking state of the side block can be released.

[0018] At this time, the storage box and the side blocks can be moved out, so that the rescuers can take out the first aid equipment inside and provide emergency treatment to the rescued person. When the rescuers sit on the seat board, the storage box and the side blocks are braked again to prevent the storage box from popping out during the lifting process, causing the first aid equipment to fall off;

[0019] Under normal circumstances, the device casing moves down slowly, and the support plate always maintains a certain height under the elastic force of the first spring. At this time, the gear and the rack are not in contact. When the device casing falls quickly, the support plate is in a weightless state, and the height of the support plate will move slightly upward relative to the bottom of the device casing, and the rack is meshed with the gear. At this time, the rotating gear drives the two racks away from each other, and the two racks drive the L-shaped push plate away. In the initial state, the L-shaped push plate is located below the strip hole. At this time, the L-shaped push plate is on the same horizontal line as the strip hole. The L-shaped push plate passes through the strip hole and pushes the side plate to move laterally. The side plate drives the fixed tip to move laterally, and the fixed tip conflicts with the well wall, thereby increasing the friction of the device and ensuring the stability of the device casing. In addition, the L-shaped push plate can also drive the rectangular block to move when moving, and the rectangular block contacts the elastic switch, so that the servo motor can be turned off in time to prevent the device casing from continuing to fall.

[0020] Beneficial effect: Through the storage box and brake assembly, rescuers can conveniently store and take out first aid tools. When rescuing the rescued person, the rescuer only needs to move away from the seat board, and the storage box can be automatically unlocked under the action of the tension spring, so that the rescuer can quickly take out the first aid tools.

[0021] Using servo motors and friction rollers, rescuers can precisely control the descent speed of the device to ensure a smooth and safe descent.

[0022] The anti-fall components installed on both sides of the device shell can be quickly activated when the device falls rapidly, and the friction is increased by the contact between the fixed tip and the well wall, thereby stabilizing the device. In addition, the L-shaped push plate and the elastic switch can be used together to turn off the servo motor in time in an emergency to prevent the device from continuing to fall.

[0023] The design of the seat board not only provides a comfortable riding experience, but also increases the stability of the structure through the reinforcement board. At the same time, the use of the first elastic strap and the second elastic strap further ensures the safety of the rescuers during the descent. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, if emergency treatment is needed for the rescued person, the rescuer can move away from the top of the seat plate 6, and then the sliding plate 10 is not under pressure, and the connecting block 11 moves up under the tension of the tension spring 12, and the connecting block 11 drives the sliding plate 10 to move up, and the connecting block 11 drives the internal cross plate 27 to move up at the same time, and the cross plate 27 drives the positioning rod 28 to move up, and the positioning rod 28 moves out of the inside of the positioning groove 29, so that the braking state of the side block 19 can be released. At this time, the storage box 7 and the side block 19 can be moved out, so that it is convenient for the rescuer to take the first aid tools inside and provide emergency treatment to the rescued person. When the rescuer sits on the seat plate 6, the storage box 7 and the side block 19 are braked again to avoid the storage box 7 popping out during the lifting process, resulting in the first aid tools falling off;

[0035] A fixing plate 18 is fixedly connected to the inner wall of the device housing 1, a counterweight 23 is fixedly connected to one side of the top of the fixing plate 18, a control component for controlling the downward movement of the device is arranged on one side of the counterweight 23, and the control component includes two rotating shafts 32 symmetrically arranged and rotatably connected to one side of the counterweight 23, and a friction roller 15 is fixedly sleeved on the outer wall of the rotating shaft 32, and the two friction rollers 15 are respectively located on both sides of the safety rope 9 and used in conjunction with the safety rope 9, a servo motor 16 is fixedly connected to the inner wall of one side of the device housing 1, and the output shaft of the servo motor 16 is fixedly connected to one end of one of the rotating shafts 32, and the same support plate 20 is slidably connected between the inner walls of both sides of the device housing 1, and two symmetrically arranged first springs 17 are fixedly connected between the bottom of the support plate 20 and the top of the fixing plate 18, supporting The top of the plate 20 is slidably connected with two racks 33 which are symmetrical to the center. The outer wall of the rotating shaft 32 is fixedly sleeved with a gear 21. The two gears 21 are meshed and staggered. The two gears 21 are respectively meshed with the two racks 33. One end of the rack 33 is fixedly connected with an L-shaped push plate 30. The rescuer sits on the seat plate 6. The device housing 1 is attached to the safety rope 9 as a whole. Due to the friction between the friction roller 15 and the safety rope 9, the device housing 1 cannot be directly moved down. The servo motor 16 is started. The output shaft of the servo motor 16 drives one of the rotating shafts 32 to rotate. The rotating shaft 32 drives the other rotating shaft 32 to rotate through the gear 21. At this time, the two rotating shafts 32 drive the two friction rollers 15 to rotate. The friction rollers 15 rotate and make the device housing 1 slowly move down along the side block 19.

[0036] Both sides of the device housing 1 are provided with anti-falling components for preventing the device housing 1 from falling. The anti-falling components include two round rods 26 symmetrically arranged and slidingly passing through one side of the device housing 1. One end of the round rod 26 is fixedly connected to a limit block 25. A second spring 24 is fixedly connected between one side of the limit block 25 and an inner wall of one side of the device housing 1. The second spring 24 is sleeved on the round rod 26. The other ends of the two round rods 26 are fixedly connected to a side plate 2. One side of the side plate 2 is provided with a plurality of fixed tips 3. Both sides of the device housing 1 are provided with strip holes 34. L-shaped push plates 30 are used in conjunction with the strip holes 34. The L-shaped push plates 30 are used to push the side plates 2 to move laterally. A rectangular block 31 is fixedly connected to one side of one of the L-shaped push plates 30. An elastic switch 22 electrically connected to the servo motor 16 is provided on the inner wall of one side of the device housing 1. The rectangular block 31 is used in conjunction with the elastic switch 22. Under normal circumstances, the device housing 1 moves down slowly, and the support plate 20 is supported by the first spring 1 7 always maintains a certain height under the elastic force of the gear 21. At this time, the gear 21 is not in contact with the rack 33. When the device housing 1 falls rapidly, the support plate 20 is in a weightless state, and the height of the support plate 20 will slightly move up relative to the bottom of the device housing 1. The rack 33 is meshed with the gear 21. At this time, the rotating gear 21 drives the two racks 33 to move away from each other, and the two racks 33 drive the L-shaped push plate 30 to move away. In the initial state, the L-shaped push plate 30 is located below the strip hole 34. At this time, the L-shaped push plate 30 is located on the same horizontal line as the strip hole 34. The L-shaped push plate 30 passes through the strip hole 34 and pushes the side plate 2 to move horizontally. The side plate 2 drives the fixed tip 3 to move horizontally, and the fixed tip 3 conflicts with the well wall, thereby increasing the friction of the device and ensuring the stability of the device housing 1. In addition, the L-shaped push plate 30 can also drive the rectangular block 31 to move when moving. The rectangular block 31 contacts the elastic switch 22, and the servo motor 16 can be turned off in time to prevent the device housing 1 from continuing to fall.
