It is usually used in various emergency situations, such as building collapse, mining disasters, traffic accidents, high-altitude operation accidents and other scenarios. Lifting rescue can provide timely rescue services for trapped people. In an environment without electricity, traditional electric-driven equipment may not be able to be used. Non-electric deep-well lifting rescue is not restricted by power supply and can be carried out in a variety of complex and harsh environments, such as remote areas, natural disaster sites, etc. Therefore, non-electric deep-well lifting rescue can provide timely rescue services for trapped people.

[0022] Compared with the prior art, the embodiments of the present invention have the following advantages:

[0023] (1) An embodiment of the present invention provides a non-electric lifting and rescue device, including a mobile body and a telescopic component, a power transmission mechanism, a conversion mechanism, a squeezing mechanism, a power selection mechanism, and a sorting mechanism arranged on the mobile body. The power transmission mechanism includes a winding mechanism, a transmission mechanism, a release mechanism, and a pushing mechanism. The rescuer first controls the power selection mechanism by operating the squeezing mechanisms on both sides, so that the power selection mechanism is not connected to the winding mechanism and the release mechanism. Then, the rescuer operates the control handle of the telescopic component so that the output end of the telescopic component extends to the trapped person, and the foot support plate achieves a supporting effect on the trapped person. Then, the trapped person controls the squeezing mechanism to drive the power selection mechanism to move, so that one power selection mechanism is connected to the release mechanism, and the other power selection mechanism is connected to the winding mechanism. At this time, the trapped person's two feet are on the output end of the telescopic component. At the same time, the two rescuers respectively grasp the telescopic components. One foot of the trapped person applies force, and the force-applying foot is connected to the release mechanism. The other foot is separated from the output end of the telescopic component as much as possible and corresponds to the reeling component. At the same time, the rescuer releases a telescopic component, so that the output end of the telescopic component drops a certain distance. The telescopic component drives the release component to move, and the release component drives the push component to move, so that the conversion component moves, thereby causing another conversion component to move accordingly, forcing another push component to move, and the push component drives the reeling component to move, so that the reeling component drives the other telescopic component to continuously shrink, so that the output end of the telescopic component rises a certain distance. Due to the difference between the release component and the reeling component, the rising distance is greater than the falling distance, achieving the effect of one telescopic component dropping a short distance and the other telescopic component rising a long distance, so that the trapped person continues to rise from the narrow space under the actions of himself and the rescuers until he rises to the rescuers and is pulled up by the rescuers to complete the rescue, thereby improving the flexibility and initiative of the non-electric lifting and rescue equipment;

[0024] (2) The arrangement of the tidying component can achieve the tidying effect on the rescue rope, so that the rescue rope is dispersed on the roller, avoiding the rescue rope from piling up, achieving the effect of spreading the rescue rope, improving the automation degree of the device, improving the rationality of the device, and not affecting the release of the rescue rope when releasing; the arrangement of the transmission component enables the first sleeve to drive the shaft and the roller to rotate and reel in the rescue rope while achieving the tidying effect on the rescue rope, avoiding the rescue rope from piling up and being unable to be reeled in, which is conducive to the reeling of the rescue rope, and when the roller releases the rescue rope, the rescue rope is released smoothly, thereby improving the flexibility of the non-electric lifting and rescue device;

[0025] (3) The trapped persons are rescued by themselves and rescued by rescuers together. The trapped persons use their own weight to concentrate the force on one foot, so that the rescue rope on one side is subjected to force and the other is not subjected to force as much as possible. The rescue rope on one side is lowered a small distance and the rescue rope on the other side is raised a large distance. The rescue work of the trapped persons is completed, which greatly reduces the labor intensity and difficulty of the rescuers. The trapped persons actively participate in self-rescue, which reduces the fear of the trapped persons, improves the flexibility and initiative of the non-electric lifting and rescue equipment, and is conducive to the development of rescue work.

[0043] An embodiment of the present invention provides a non-electric lifting and rescue device. In this embodiment, a non-electric lifting and rescue device includes a mobile body and a telescopic component, a power transmission mechanism, a conversion component, an extrusion component, a power selection component, and a finishing component arranged on the mobile body. The mobile body is provided with a first limit hole that runs through the mobile body, and the power transmission mechanism includes a winding component, a transmission component, a release component, and a pushing component. The conversion component includes a conduit, and the two ends of the conversion component are symmetrically provided with a telescopic component, a power transmission mechanism, a power selection component, and an extrusion component, and a second fixing plate is provided on the mobile body.

[0044] It should be noted that during rescue, the device is moved to the rescue position by moving the vehicle body. The rescuers operate the squeezing components on both sides to first control the power selection components, so that the power selection components are not connected to the winding component and the releasing component. Then, the telescopic components are operated to extend the output end of the telescopic components to the trapped persons. The trapped persons control the squeezing components to drive the power selection components to move, so that one power selection component is connected to the releasing component, and the other power selection component is connected to the winding component. At this time, the trapped persons step on the output end of the telescopic components with both feet, and one of the trapped persons applies force, and the force-applying foot corresponds to the releasing component, and the other foot is separated from the output end of the telescopic components as much as possible, corresponding to the winding component. At the same time, the rescuers release one telescopic component, so that the telescopic components The output end of the component drops a certain distance, the telescopic component drives the release component to move, the release component drives the push component to move, the conversion component moves, thereby causing another conversion component to move accordingly, forcing another push component to move, the push component drives the winding component to move, thereby causing the winding component to drive the other telescopic component to continuously shrink, causing the output end of the telescopic component to rise a certain distance. Due to the difference between the release component and the winding component, the rising distance is greater than the falling distance, achieving the effect of one telescopic component dropping a short distance and the other telescopic component rising a long distance. The above steps are repeated continuously, so that the trapped persons continue to rise from the narrow space under the actions of themselves and the rescuers, until they rise to the rescuers and are pulled up by the rescuers, completing the rescue.

The first fixed plate is sleeved with a first sleeve, and the shaft rod passes through the first sleeve. One end of the first gear group is fixedly sleeved on the first sleeve, and the other end of the first gear group is rotatably connected to the rotating rod.

[0050] The setting of the winding assembly can realize the rotation of the roller, thereby realizing the winding of the rescue rope, and cooperates with the power selection assembly to realize the connection between the shaft rod and the first sleeve, forming a winding system, improving the flexibility of the device, and making the winding length of the rescue rope longer, thereby realizing the continuous ascent of the trapped person.

[0051] As an embodiment of the present application, the first gear set includes a first winding gear, a second winding gear, a third winding gear and a fourth winding gear, a total of four gears. As for the selection of the number of winding gears, as other implementations, the implementer can select it at will, and the present application does not impose any special restrictions on this.

[0052] Specifically, please refer to Figure 4, which is a schematic diagram showing the connection of the winding assembly, the release assembly and the pushing assembly in one embodiment of the present invention. In Figure 4, 306 is a rotating rod, 3 is a winding assembly, 4 is a releasing assembly, and 6 is a pushing assembly. Specifically, please refer to Figure 5, which is a schematic diagram showing the structure of the winding assembly in one embodiment of the present invention. In Figure 5, 301 is a first fixed plate, 302 is a first sleeve, 303 is a first winding gear, 304 is a second winding gear, 305 is a third winding gear, 306 is a rotating rod, and 307 is a fourth winding gear.

[0054] It should be noted that the setting of the release component enables the rescue personnel to release the rescue rope first, thereby obtaining power to realize the reeling effect of the rescue rope on the other side, and cooperate with the power selection component to realize the connection between the shaft rod and the second sleeve, forming a release system, improving the flexibility of the device, and making the reeled length of the rescue rope greater than the released length of the rescue rope on the other side, thereby realizing the continuous ascent of the trapped persons.

[0055] Specifically, please refer to Figure 6, which is a schematic diagram of the structure of a release assembly in one embodiment of the present invention. In Figure 6, 402 is a second sleeve, 403 is a first release gear, and 404 is a second release gear.

[0056] The conversion assembly also includes a cylinder, a support plate symmetrically arranged on the mobile body, a cylinder is arranged on the support plate, and the two ends of the conduit are respectively connected to a cylinder. Specifically, please refer to Figure 7, which shows a schematic diagram of the structure of the conversion assembly in one embodiment of the present invention. In Figure 7, 501 is a support plate, 502 is a cylinder, and 503 is a conduit.

[0057] It should be noted that the setting of the conversion component can exchange the gas in the two cylinders, thereby realizing the conversion of the force of the two pushing components, so that the force of the rescue rope descending on one side is converted into the force of the rescue rope rising on the other side. By exchanging and repeating the operation on both sides, the rescue rope is continuously pulled up to realize the control of the device.

[0058] The squeezing assembly includes a cylinder, a squeezing rod, a connecting pipe and an airbag arranged on the rescue rope. The cylinder is fixedly arranged on the second fixing plate. The connecting pipe connects the cylinder and the airbag. A squeezing plug is arranged in the cylinder. The squeezing rod is movably connected to the squeezing plug and the power selection assembly.

The power selection assembly can be in friction contact with the power transmission mechanism, and the power transmission mechanism is connected to the driving end of the telescopic assembly.

[0060] It should be noted that the setting of the extrusion assembly can achieve the control effect on the power selection assembly. When the airbag is not pressed, due to the action of the spring and the gas, the extrusion plug drives the extrusion rod to retreat, so that the power selection assembly returns to its original position and is connected to the release assembly. When the airbag is pressed, due to the action of the gas, the extrusion plug drives the extrusion rod to move, so that the power selection assembly is connected to the winding assembly. The setting of the power selection assembly can achieve the control effect on the friction cone sleeve. When the airbag is not pressed, the friction cone sleeve is in close friction contact with the second sleeve and the shaft rod to form a whole. When the airbag is pressed, the friction cone sleeve is in close friction contact with the first sleeve and the shaft rod to form a whole, thereby improving the flexibility and rationality of the device.

One end of the connecting rod is hinged to a point on the turntable away from the center of a circle, and the other end of the connecting rod is hinged to the pushing rod. The pushing rod is provided with a pushing piston located in a cylinder.

[0063] It should be noted that the setting of the pushing assembly can realize reciprocating motion, so that the gas in the cylinder is continuously compressed or expanded, thereby driving the gas in the cylinder on the other side to continuously expand or compress, so that the pushing assembly on the other side can realize reciprocating motion, thereby realizing the continuous rotation of the rotating rod, which is conducive to the winding action of the rescue rope.

[0064] Specifically, please refer to Figure 10, which shows a schematic diagram of the connection between the pushing assembly and the winding assembly in one embodiment of the present invention. In Figure 10, 306 is a rotating rod, 601 is a rotating disk, 602 is a connecting rod, 603 is a pushing rod, and 604 is a pushing piston.

[0066] It should be noted that the setting of the sorting component can sort the rescue rope, so that the rescue rope is dispersed on the roller, avoiding the rescue rope from piling up, spreading the rescue rope, improving the automation degree of the device, improving the rationality of the device, and does not affect the release of the rescue rope during release.

[0067] The transmission assembly is located between the first sleeve and the bidirectional threaded rod. The transmission assembly includes a first transmission gear fixedly sleeved on the first sleeve and a second transmission gear meshed with the first transmission gear. The second transmission gear is fixedly sleeved on the bidirectional threaded rod.

[0068] It should be noted that the setting of the transmission assembly can enable the first sleeve to drive the shaft and the roller to rotate to reel in the rescue rope while achieving the function of arranging the rescue rope, thereby arranging the rescue rope under reasonable circumstances, improving the flexibility of the device, facilitating the reeling and releasing of the rescue rope, and improving the flexibility of the device.

[0069] Specifically, please refer to Figure 11, which shows a schematic diagram of the connection between the finishing assembly and the transmission assembly in one embodiment of the present invention. In Figure 11, 901 is a bidirectional threaded rod, 902 is a guide rod, 903 is a slider, 904 is a second limiting hole, 1001 is a first transmission gear, and 1002 is a second transmission gear.

[0070] Working principle: During rescue, the device is moved to the rescue position by moving the vehicle body, and the height of the trapped person from the ground is measured. By incompletely squeezing the airbags on both sides, the airbags drive the squeezing plugs in the cylinder to move, and the squeezing rods on both sides drive the connecting rods to move. The connecting rod drives the support ring to be located between the first sleeve and the second sleeve, forcing the friction cone sleeve to have no friction contact with the first sleeve and the second sleeve.

[0071] Two rescuers rotate the handles at the same time, so that the handles drive the shaft to rotate, and the shaft drives the roller to rotate, forcing the roller to release the rescue rope, so that the rescue rope is released to a length equal to the measured height value, and the foot support plate reaches the trapped person, stops releasing the rescue rope, releases the airbag, and makes the two friction cone sleeves move back to their original positions, that is, the friction cone sleeves are in close friction contact with the second sleeve.

[0072] To rescue the trapped person, two rescuers control the handles, the trapped person stands on the footrest with two feet, holds the rescue rope with two hands, and one hand completely squeezes the airbag, so that the gas enters the cylinder body through the connecting pipe, forcing the squeezing plug in the cylinder body to move, the squeezing rod drives the connecting rod to move, and the connecting rod drives the supporting ring and the friction cone sleeve to move. Since the spring is located between the connecting rod and the second fixed plate, the movement of the connecting rod will drive the spring to stretch until the friction cone sleeve is in close contact with the first sleeve, so that the friction cone sleeve on the other side is in close friction contact with the first sleeve and the shaft rod to form a whole, and the friction cone sleeve on one side is in close friction contact with the second sleeve and the shaft rod to form a whole;

[0073] The trapped person uses his own weight to concentrate the force on one foot, so that the rescue rope on one side is subjected to force, and the other side is not subjected to force as much as possible. At the same time, the rescuer cooperates with the trapped person to slowly release the handle on one side, and the shaft rod rotates, driving the roller to rotate, so that the rescue rope slowly drops a distance, and the shaft rod rotation drives the second sleeve to rotate, and the second sleeve drives the first release gear to rotate, forcing the second release gear to rotate, and the second release gear drives the rotating rod to rotate, and the rotating rod drives the turntable to rotate, and the turntable drives the connecting rod to move, and the connecting rod drives the push rod to move back and forth, so that the push rod drives the push piston to move back and forth, so that the gas in the cylinder on one side enters the cylinder on the other side through the conduit, and the cylinder on the other side drives the push piston and the push rod to move back and forth, so that the push rod drives the connecting rod to move, and the connecting rod drives the turntable to rotate, so that the turntable rotates continuously. At this time, the friction cone sleeve on the other side is tightly rubbed against the first sleeve and the shaft rod. The rubbing contact forms an integral whole, the rotation of the rotating rod drives the fourth winding gear to rotate, the fourth winding gear drives the third winding gear to rotate, and drives the second winding gear to rotate, forcing the first winding gear to rotate, thereby making the first sleeve rotate, and the first sleeve drives the shaft rod to rotate, forcing the roller to rotate, thereby realizing the winding action of the rescue rope on the other side. Since the diameter of the first releasing gear is larger than the diameter of the second releasing gear, the winding length of the rescue rope on the other side is greater than the releasing length of the rescue rope on one side. Therefore, the rising height of the rescue rope on the other side is greater than the falling height of the rescue rope on one side, achieving the effect of the rescue height decreasing a small section and rising a large section, and ensuring that the rescue ropes on both sides are always in a reasonable position that the trapped persons can reach, and constantly repeating the above steps, so that the trapped persons continue to rise from the narrow space under the actions of themselves and the rescuers, until they rise to the rescuers and are pulled up by the rescuers to complete the rescue.

[0074] During the winding process of the rescue rope on the other side, the rotation of the first sleeve drives the first transmission gear to rotate and the second transmission gear to rotate, thereby causing the bidirectional threaded rod to rotate. Under the action of the guide rod, the bidirectional threaded rod drives the slider to move back and forth, and drives the rescue rope to move back and forth following the first limit hole and the second limit hole. Therefore, during the winding process of the rescue rope, the slider realizes the arranging action of the rescue rope, so that the rescue rope is continuously wound at different positions on the roller.

[0075] This scheme adopts the joint rescue of the trapped persons' self-rescue and the rescue of the rescuers, and realizes the purpose of descending a small section and rising a large section of the rescue rope, thereby realizing the rescue work of the trapped persons, greatly reducing the labor intensity and rescue difficulty of the rescuers, saving energy for the rescuers, and the trapped persons actively participate in the active self-rescue, reducing the trapped persons' fear, and facilitating the development of the rescue work. This device is particularly suitable for trapped persons who are able to move in a small space without electricity.
