Description

Technical Field

[0001] The present invention relates to the technical field of lifting devices, and in particular to an emergency rescue lifting device. Background Art

[0002] At disaster sites, such as earthquake sites, the ground is often rugged and there are various obstacles and dangerous items. Therefore, a stretcher is needed to rescue the rescued from the scene, so it is inevitable to carry the rescued; if at a traffic accident site, the ground is relatively flat, and the existing rescue beds can only complete the transfer of the wounded by carrying them. Carrying the wounded requires transferring the wounded from the ground or other locations to the rescue bed. This process requires rescuers to have skilled techniques. If the operation is improper, such as uneven force when lifting the wounded, or the injured part of the wounded is not properly fixed, it may cause secondary injuries such as dislocation of the fracture site and tearing of the wound. For the relatively flat road surface at the disaster site, a new emergency rescue device can be proposed. The emergency rescue device can complete the transfer of the wounded by other reasonable means to reduce the carrying of the wounded, greatly reducing the risk of secondary injury to the wounded caused by carrying.

[0003] When a fire occurs in a residential area, it is necessary to rescue residents trapped on high floors. Usually, a ladder truck is used. However, due to its carrying capacity, the ladder truck cannot rescue multiple trapped people at one time. Therefore, in some cases, conventional elevators are needed for auxiliary rescue. However, existing elevators, such as scissor lifts and straight arm lifts, can be close to floor windows and corridors. When they cannot be directly connected to windows and corridors, this increases the risk and difficulty of transferring trapped people to the elevator. Moreover, once the elevator cannot be close to floor windows or corridors due to ground road conditions, it will inevitably greatly increase the difficulty of rescuing trapped people. In response to this problem, a lifting device with emergency rescue function can be proposed. Summary of the invention

DETAILED DESCRIPTION

[0032] In the description of this embodiment, it should be noted that the terms "upper", "lower", "inner", "bottom", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the inventive product is usually placed when used. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0033] In the description of this embodiment, it should also be noted that, unless otherwise clearly specified and limited, the terms “set”, “connected” and “connected” should be understood in a broad sense.

[0034] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] refer to Figures 1 to 9The present embodiment discloses an emergency rescue lifting device, including a base plate 10; the base plate 10 is shaped as two axially symmetrical L-shaped plates connected to each other, and a moving assembly 120 is provided on the bottom surface of the base plate 10, and the moving assembly 120 is divided into four groups and respectively arranged at the four corners of the base plate 10; the moving assembly 120 includes a connecting column 121, one end of the connecting column 121 is rotatably connected to a mounting plate 122, and the other end is rotatably connected to a rolling wheel 123; the mounting plate 122 is fixedly connected to the bottom surface of the base plate 10, and the rolling wheel 123 directly contacts the ground, and the moving assembly 120 can drive the base plate 10 to move.

[0036] Furthermore, a handrail 11 is provided on the top surface of the bottom plate 10 near its rear end surface; the two axially symmetrical L-shaped plates are butt-jointed to leave a hollow portion in the middle thereof, that is, the shape of the bottom plate 10 is half of the U-shape, so the bottom plate 10 will leave a hollow portion.

[0037] When the present embodiment is in use, the operator grasps and pushes the armrest 11, and the pushing force applied by the operator is sequentially transmitted to the base plate 10, the mounting plate 122, the connecting column 121 and the rolling wheel 123 through the armrest 11. Under the action of the pushing force, the rolling wheel 123 rolls along the ground, thereby driving the connecting column 121, the mounting plate 122 and the base plate 10 connected thereto to move together, thereby realizing the overall movement of the present invention; when the operator grasps and rotates the armrest 11, the torque applied by the operator is sequentially transmitted to the base plate 10, the mounting plate 122, the connecting column 121 and the rolling wheel 123 through the armrest 11. Under the action of the torque, with a certain rolling wheel 123 as a fulcrum, the rolling wheel 123 as a fulcrum and the connecting column 121 connected thereto remain relatively still with the ground, the mounting plate 122 at the fulcrum and the connecting column 121 rotatably connected thereto rotate, and the other three rolling wheels 123 rotate around the fulcrum, thereby driving the base plate 10 to rotate together, thereby realizing the overall rotation of the present invention. The present invention utilizes the mobile assembly 120 to push the present invention to a specific location where emergency rescue is required, such as ground rescue, high-altitude rescue, etc., and no manual handling is required during the transportation of rescue personnel, which effectively saves the operator's physical strength so as to rescue more people.

[0038] As a further solution of this embodiment: two groups of first columns 130 are symmetrically provided on the top surface of the base plate 10, and the first columns 130 are provided with first sliding grooves 131 along their vertical direction; the first sliding grooves 131 are rotationally and slidingly connected to the first rotating shaft 202, the first rotating shaft 202 is connected to one end of the first rotating rod 203, and the other end of the first rotating rod 203 is rotationally connected to one side of the base plate 210.

[0039] Furthermore, one end of the first rotating shaft 202 is connected to the first motor 201, that is, the first rotating shaft 202 is connected to the output shaft of the first motor 201; the connection method between the first rotating shaft 202 and the first rotating rod 203 adopts a fixed connection, so as to ensure that they can rotate synchronously; there are two first rotating rods 203, and the two first rotating rods 203 are respectively close to the inner side surfaces of the two groups of first columns 130, and the two first rotating rods 203 are respectively close to the front and rear ends of the base plate 210; a second rotating shaft is provided on one side of the base plate 210, and the second rotating shaft is rotatably connected to the first rotating rod 203.

[0040] The specific operation is as follows: when the first motor 201 rotates forward, the first motor 201 drives the first rotating shaft 202 connected thereto to rotate together, and the first rotating shaft 202 drives the first rotating rod 203 connected thereto to rotate synchronously, and at this time the first rotating rod 203 moves toward the hollow part of the bottom plate 10 until the first rotating rod 203 completely passes through the hollow part of the bottom plate 10 and approaches the ground, and the base plate 210 rotatably connected to the first rotating rod 203 also moves therewith, and the base plate 210 will gradually move away from the hollow part at the bottom under the push of the first rotating rod 203. On the contrary, when the first motor 201 rotates reversely, the first rotating shaft 202 will drive the first rotating rod 203 to rotate in the direction away from the hollow part of the bottom plate 10, and at this time the base plate 210 moving along with it will return to its original position under the pull of the first rotating rod 203, and the position is located above the hollow part of the bottom plate 10; when the first rotating rod 203 is close to vertical, the base plate 210 and the bottom plate 10 are away from each other.

[0041] As a further solution of this embodiment: the other side of the base plate 210 is rotatably connected to one end of the second rotating rod 204, and the other end of the second rotating rod 204 is rotatably connected to the first roller 205; an adjusting rod assembly 300 is provided between the second rotating rod 204 and the bottom surface of the base plate 210, and the adjusting rod assembly 300 includes a rack 310, the back of the rack 310 is connected to the bottom surface of the base plate 210, the rack 310 is meshedly connected to the gear 320, the gear 320 is connected to the adjusting rod motor 330, and the adjusting rod motor 330 It is connected to an adjusting rod crossbeam 340, which is parallel to the base plate 210 and connected to an adjusting rod slider 350, which is slidably connected to an adjusting rod slide rail 360, which is parallel to the rack 310 and connected to the bottom surface of the base plate 210; the adjusting rod slider 350 is rotationally connected to one end of an adjusting rod 370, and the other end of the adjusting rod 370 is rotationally connected to the second rotating rod 204; the adjusting rod assembly 300 can adjust the inclination of the second rotating rod 204 relative to the base plate 210.

[0042] Furthermore, there are two second rotating rods 204, which are respectively close to the front and rear ends of the base plate 210; there are two adjusting rods 370 connected to the second rotating rod 204, there are two adjusting rod sliders 350 rotatably connected to the adjusting rod 370, and there are two adjusting rod slide rails 360 slidably connected to the adjusting rod sliders 350; there is one rack 310, which is located in the middle position of the two adjusting rod slide rails 360; a third rotating shaft is provided on the other side of the base plate 210, and the third rotating shaft is rotatably connected to the second rotating rod 204; the gear 320 is connected to the output shaft of the adjusting rod motor 330.

[0043] The specific operation is as follows: when the lever motor 330 rotates forward, the gear 320 connected thereto rotates forward. Since the rack 310 is fixed to the bottom surface of the base plate 210, the meshing movement of the gear 320 and the rack 310 is converted into a linear movement of the lever motor 330 along the rack 310. At this time, the lever motor 330 moves along the rack 310 toward the side of the base plate 210 that is rotated and connected to the first rotating rod 203. The movement of the lever motor 330 drives the lever crossbeam 340 connected thereto to move together. The lever crossbeam 340 drives the lever crossbeam 340 connected thereto to move together. The rod adjustment slider 350 connected thereto moves together, and at this time, the rod adjustment slider 350 slides along the rod adjustment rail 360. During the sliding process, the rod adjustment slider 350 drives the adjustment rod 370 connected thereto to rotate, and the rotated adjustment rod 370 pulls the second rotation rod 204 to rotate toward the bottom surface of the base plate 210, and the first roller 205 connected thereto can roll along the ground; when the second rotation rod 204 is close to vertical, at this time, there will be a large gap between the base plate 210 and the bottom plate 10 in their vertical direction. On the contrary, when the rod adjustment motor 330 reverses, the rod adjustment assembly 300 adjusts the second rotation rod 204 to rotate toward the top surface of the base plate 210 until the second rotation rod 204 and the base plate 210 are located in the same horizontal plane.

[0044] As a further solution of this embodiment: a sliding plate 220 is provided on the top of the base plate 210, and the sliding plate 220 is used to carry the human body. A positioning assembly 400 is provided between the sliding plate 220 and the base plate 210, and the positioning assembly 400 is used to fix the sliding plate 220 and the base plate 210; a protruding horizontal plate 211 is provided in the middle part of the front and rear end surfaces of the base plate 210, and the horizontal plate 211 is provided with a horizontal slide groove 212, and the positioning assembly 400 is arranged in the horizontal slide groove 212, and the positioning assembly 400 includes a positioning spring 410, and the positioning spring 410 is connected to the inner surface of the horizontal slide groove 212 and the positioning cylinder 420, and the front end surface of the positioning cylinder 420 is directly opposite to the sliding plate 220, and the front end surface of the positioning cylinder 420 is provided with a first positioning groove 42 1. A second positioning groove 422 is provided on one side of the positioning cylinder 420, a positioning block 430 is slidably connected in the positioning cylinder 420, a positioning rod 440 is connected to the front end surface of the positioning block 430, and the positioning rod 440 can be slidably connected with the first positioning groove 421 and the second positioning groove 422 respectively; when the positioning rod 440 is slidably connected with the first positioning groove 421, the positioning rod 440 can pass through the sliding plate 220 and be inserted into the base plate 210 under the push of the positioning spring 410, so as to fix the sliding plate 220 and the base plate 210; when the positioning rod 440 is slidably connected with the second positioning groove 422, the positioning rod 440 is located on the side of the positioning cylinder 420, and the sliding plate 220 can slide relative to the base plate 210.

[0045] Furthermore, positioning holes are reserved on the sliding plate 220 and the base plate 210 to facilitate the insertion of the positioning rod 440 for positioning.

[0046] The specific operation is as follows: under normal conditions, the positioning spring 410 is in an extended state, the positioning rod 440 is located in the first positioning slot 421 , and passes through the sliding plate 220 and the base plate 210 in sequence, thereby keeping the sliding plate 220 and the base plate 210 fixed. When the positioning assembly 400 needs to be released, the operator holds the positioning cylinder 420 and slides it along the horizontal slide groove 212. The positioning cylinder 420 compresses the horizontal slide groove 212, and the positioning rod 440 is taken out from the base plate 210 and the sliding plate 220; then, the positioning block 430 is taken out from the positioning cylinder 420, and the positioning rod 440 connected with the positioning block 430 is taken out from the first slide groove 131 of the positioning cylinder 420, and then the positioning rod 440 is aligned with the second slide groove 132, and then put into the positioning cylinder 420 together with the positioning block 430. At this time, the operator releases the positioning cylinder 420, and the positioning cylinder 420 returns to its original position under the push of the positioning spring 410. However, since the positioning rod 440 is located on the side of the positioning cylinder 420, the positioning rod 440 no longer contacts the base plate 210 and the sliding plate 220. The sliding plate 220 and the base plate 210 can move relative to each other after losing fixation. When the base plate 210 and the sliding plate 220 need to be re-fixed, the operation process is the opposite of the above operation process. This arrangement can effectively avoid interference of the positioning assembly 400 with the base plate 210 and the sliding plate 220 , and does not require the operator to continuously hold the device for operation, thereby effectively reducing the operator's workload.

[0047] As a further solution of this embodiment: the sliding plate 220 is provided with a slideway 221, and the slideway 221 is rollingly connected with multiple pulley components 700, and the multiple pulley components 700 are respectively arranged on the top surface of the substrate 210 and the corresponding sides of the second rotating rod 204; each pulley component 700 includes multiple sliding shafts 710, one end of each sliding shaft 710 is rotatably connected to the left plate 720, and the other end is rotatably connected to the right plate 730, the sliding shaft 710 can extend from the left plate 720 and the right plate 730, the left plate 720 and the right plate 730 are both connected to the top surface of the substrate 210 or the corresponding side of the second rotating rod 204, and the outer side of each sliding shaft 710 is sleeved with a sliding wheel 740, and each sliding wheel 740 rotates relative to the left plate 720 and the right plate 730.

[0049] The specific operation is as follows: after releasing the fixing of the positioning assembly 400 to the base plate 210 and the sliding plate 220, the operator can hold the handle 223 and drag the sliding plate 220 to move along the base plate 210 and the second rotating rod 204. During the movement of the sliding plate 220, the slideway 221 moves along the pulley component 700 to ensure that the sliding plate 220 will not be separated from the pulley component 700 during the movement; and the sliding wheel 740 changes the sliding process of the sliding plate 220 along the base plate 210 and the second rotating component into a rolling process, which effectively reduces the friction during the movement of the sliding plate 220 and facilitates the operator to push and pull the sliding plate 220. After placing the person who needs rescue on the sliding plate 220, the fixing assembly 222 set on the sliding plate 220 can be used to fix the injured person to prevent the injured person from being injured again during transportation.

[0052] The purpose of setting the sliding motor 760 and the conveyor belt 750 is to enable the pulley component 700 to drive itself, further reducing the physical effort of the operator. In actual situations, the technicians can choose whether to add the sliding motor 760 and the conveyor belt 750 to the pulley component 700 according to different rescue situations.

[0054] Furthermore, the winding machine 144 is of prior art, and comprises a winding motor and a cable reel. The cable reel is driven by the winding motor to rotate, and the cable reel is wound and connected with a cable, and can wind or release the cable.

[0055] The specific operation is as follows: when the first motor 201 and the rod adjustment motor 330 drive the first rotating rod 203 and the second rotating rod 204 to be located at the bottom of the base plate 210 and close to vertical, the base plate 210 and the bottom plate 10 remain parallel, and there is a large distance between the two along their vertical direction, the operator can release the cable 143 through the winding machine 144, and the winding wheel 142 acts as a turning point during the lifting process of the cable 143. The cable 143 passes through the winding wheel 142 and is moved on the lifting hook 1 45 can remain in a straight state under its own gravity. As the lifting hook 145 gradually approaches the semicircular buckle 640 and the two reach the same position height, the lifting hook 145 is connected to the semicircular buckle 640, and then the cable 143 is continuously wound by the winding machine 144. The cable 143 is pulled by the winding machine 144 through the winding wheel 142, and the base plate 210 and the shock absorbing assembly 600 and other components are lifted by the lifting hook 145. At this time, the first motor 201 and the first rotating shaft 202 slides upward along the first slide groove 131 under the pull of the first rotating rod 203; when the base plate 210 and the shock absorbing assembly 600 and other components are in a mid-air state under the pull of the lifting assembly 140, the lifting hook 145 pulls the semicircular buckle 640, and the semicircular buckle 640 drives the shock absorbing sleeve 630 connected thereto to move together, and the shock absorbing sleeve 630 pushes the shock absorbing spring 620 to move upward, and the base plate 210 drives the shock absorbing rod 610 connected thereto due to its own gravity to apply a downward force on the shock absorbing spring 620, and the shock absorbing spring 620 is compressed by both the shock absorbing sleeve 630 and the shock absorbing rod 610. By providing the shock absorbing spring 620, the rigid connection between the lifting assembly 140 and the base plate 210 can be avoided, and the vibration of the base plate 210 when being pulled by the lifting assembly 140 can be reduced, and the influence of the vibration caused by the ground road conditions on the base plate 210 and the sliding plate 220 on its top is reduced, and the possibility of secondary injury to the rescued personnel on the sliding plate 220 is further reduced. By providing the lifting assembly 140, the present invention can be used as a temporary rescue bed with a lifting function. The rescue bed can be raised or lowered according to the operation requirements of medical staff and the condition of the injured.

[0056] As a further solution of this embodiment: the first column 130 is further provided with a second slide groove 132 along its vertical direction, the second slide groove 132 is rotatably and slidably connected to the limiting assembly 500, the limiting assembly 500 includes a limiting cylinder 510, the limiting cylinder 510 is rotatably and slidably connected to the second slide groove 132, the limiting cylinder 510 is connected to a limiting end cover 520 at an opening at one end, the limiting end cover 520 is connected to one end of a limiting spring 530, the other end of the limiting spring 530 is connected to a limiting rod 540, the limiting spring 530 is located in the limiting cylinder 510 and is sleeved on the outside of the limiting rod 540, the limiting rod 540 vertically passes through the limiting end cover 520 in sequence 0 and the limiting cylinder 510; when the limiting spring 530 is in an extended state, the limiting spring 530 can push the limiting rod 540 to insert into the substrate 210; when the limiting spring 530 is in a compressed state, the limiting rod 540 maintains a distance from the substrate 210; the limiting assembly 500 limits the substrate 210 to move only along the vertical direction of the first column 130; when the substrate 210 is disconnected from the lifting assembly 140, the limiting assembly 500 is released, and the substrate 210 can move freely relative to the first column 130; when the substrate 210 is connected to the lifting assembly 140, the limiting assembly 500 limits the movement of the substrate 210.

[0057] Furthermore, vertical slide slot holes 133 are respectively opened on the left and right sides of the second slide slot 132, and the vertical slide slot hole 133 is rotatably and slidably connected with a rotating block 511. The rotating block 511 is a protruding block on the left and right sides of the limiting cylinder 510, and the rotating block 511 is a circular block; there is a limiting hole at the position where the limiting rod 540 is inserted into the substrate 210.

[0058] The specific operation is as follows: first, the lifting assembly 140 drives the substrate 210 to move downward until the first roller 205 connected by the second rotating rod 204 contacts the ground, and the lifting assembly 140 stops working. The operator removes the lifting hook 145 from the semicircular buckle 640, thereby disconnecting the connection between the substrate 210 and the lifting assembly 140; then, the operator pulls the limit rod 540 extending from the limit end cover 520, and the limit rod 540 compresses the limit spring 530. As the operator pulls, the limit rod 540 is gradually withdrawn from the substrate 210, and the limit rod 540 loses the restriction on the substrate 210. At this time, the limit assembly 500 can be rotated around the rotating block 511, so that the limit rod 540 is completely in the second sliding groove 132, thereby avoiding the interference of the limit assembly 500 with the movement of the first rotating rod 203 and the substrate 210; then, the rotation of the first motor 201 can drive the substrate 210 to move with it. On the contrary, when the substrate 210 is connected to the lifting assembly 140, the first rotating rod 203 and the second rotating rod 204 are both located at the bottom of the substrate 210, and both are close to vertical. At this time, the limiting assembly 500 is slid from the bottom of the second slide groove 132 hole to the height of the substrate 210, and then the limiting cylinder 510 is rotated around the rotating block 511, so that the limiting rod 540 passing through the limiting cylinder 510 is facing the substrate 210, and then the limiting rod 540 is inserted into the reserved socket of the substrate 210. During the movement of the lifting assembly 140 pulling the substrate 210 to rise, the substrate 210 can only move in the vertical direction and cannot move in other directions, thereby ensuring the stability of the substrate 210 being pulled by the lifting assembly 140, thereby improving the safety factor of the present invention.

[0059] As a further solution of this embodiment: when the base plate 210 is disconnected from the lifting assembly 140, the first rotating shaft 202 drives the first rotating rod 203 to rotate toward the hollow part of the bottom plate 10, and at the same time, the adjusting rod assembly 300 adjusts the second rotating rod 204 and the base plate 210 to be located at the same horizontal plane, and the first roller 205 rolls along the ground, so that the base plate 210 gradually approaches the ground, and then the positioning assembly 400 is released, and the sliding plate 220 can slide along the base plate 210 to the second rotating rod 204, and continue to slide along the second rotating rod 204, and finally approach the first roller 205, at this time, the sliding plate 220 close to the ground; when the base plate 210 is connected to the lifting assembly 140, the first rotating rod 203 and the second rotating rod 204 are both located below the base plate 210 and are close to vertical; when the lifting assembly 140 drives the base plate 210 to rise to a certain height, the adjusting rod assembly 300 adjusts the second rotating rod 204 and the base plate 210 to be located in the same horizontal plane. At this time, the second rotating rod 204 can be overlapped on an object of corresponding height, and the positioning assembly 400 is released. The sliding plate 220 can slide along the base plate 210 to the second rotating rod 204, and continue to slide along the second rotating rod 204, and finally close to the first roller 205.

[0060] First of all, the present invention can cope with different rescue scenarios by switching between different change states and changing the order of use of each change state. The rescue scenarios of the present invention are mainly used for: ground rescue and high-altitude rescue. Among them, when the present invention undertakes ground rescue tasks, it is mainly to replace the existing liftable rescue beds, such as hydraulic lift rescue beds and electric lift rescue beds, etc., as well as to replace some application scenarios of stretchers, such as when the road conditions on the rescue ground are relatively good; when the present invention undertakes high-altitude rescue tasks, it is mainly to solve the drawbacks of existing elevators when performing rescue, such as when a scissors-type lift performs a rescue task, if it cannot get close to the floor window, the difficulty of the trapped persons to obtain rescue is greatly increased. Figures 1 to 3 As shown, the use sequence for ground rescue is: the first change state of the present invention, the second change state of the present invention, and the third change state of the present invention. The specific operation process is as follows: when there are people who need to be rescued on the ground, the present invention switches to the first change state, such as Figure 1 As shown, at this time, the rescuer uses the moving assembly 120 to approach the person to be rescued, and aligns the sliding plate 220 with the person to be rescued, then one rescuer pushes the present invention, and uses the sliding plate 220 to shovel the person to be rescued, and another rescuer assists in shoveling. After the rescued person is shoveled onto the sliding plate 220, the rescuer who assists in shoveling can push the handle 223 on the sliding plate 220, and then push the sliding plate 220 back to the top of the base plate 210, and use the positioning assembly 400 to fix the base plate 210 and the sliding plate 220; then, the first motor 201 and the adjusting rod motor 330 rotate at the same time, so that The first rotating rod 203 and the second rotating rod 204 gradually approach the vertical state. During this process, the base plate 210 always remains horizontal to prevent the personnel on the sliding plate 220 from falling from the sliding plate 220. When the first rotating rod 203 and the second rotating rod 204 reach the corresponding position, the base plate 210 is limited by the limiting assembly 500, and the lifting hook 145 is adjusted to the same height as the semicircular buckle 640 and the two are connected, so that the lifting assembly 140 is connected to the shock absorbing assembly 600 and the base plate 210, and the lifting assembly 140 is used to drive the base plate 210 and other components to move upward, thereby completing the second change state of the present invention, such as Figure 2 As shown; then, the rescuer pushes the present invention to transport the rescued person to the emergency unit, and the present invention can be switched to the third change state, such as Figure 3As shown, the third change state of the present invention is mainly used in conjunction with a hospital bed, an operating table, a camp bed, etc., and the height of the base plate 210 is adjusted by using the lifting assembly 140, so that the second rotating rod 204 can be connected to the hospital bed, the operating table, the camp bed, etc., and then the positioning assembly 400 is opened, and the rescuer drags the sliding plate 220 to a position close to the first roller 205, and then one rescuer fixes the rescued person, and the other rescuer drags the sliding plate 220 away, thereby placing the rescued person on the hospital bed or the operating table. Obviously, through the above-mentioned use process, when the present invention is used for ground rescue, it solves the problem that the rescued person needs to be manually carried in the previous stretcher rescue, and simplifies the steps that require manual carrying when the rescue bed and the hospital bed are replaced, and effectively avoids the secondary injury of the rescued person caused by the transportation, and greatly saves the physical strength of the rescuers, so that the rescuers can treat more people. The use order for high-altitude rescue is: the third change state of the present invention, the second change state of the present invention, and the first change state of the present invention. The specific operation process is as follows: when a fire occurs in a residential building and the rescued personnel cannot escape from the fire site through the safe passage, the present invention is first pushed to the window or corridor of the residential building, and then the present invention is switched to the third change state, such as Figure 3 As shown, the second rotating rod 204 is overlapped on the window or corridor, and the first roller 205 prevents the second rotating rod 204 from being separated from the window or corridor. Then the trapped person climbs onto the sliding plate 220, and then the sliding motor 760 drives the sliding wheel 740 and the conveyor belt 750 to transport the sliding plate 220 to the top of the base plate 210; then, the sliding plate 220 and the base plate 210 are fixed by the positioning assembly 400, and the lifting assembly 140 is lifted upward, the first roller 205 leaves the window or corridor, and then the adjusting rod assembly 300 adjusts the second rotating rod 204 to a vertical state, and the present invention switches to a second change state, as shown in FIG. Figure 2 Finally, the lifting assembly 140 drives the substrate 210 to move downward until the first roller 205 touches the ground, the lifting assembly 140 stops working, disconnects the lifting assembly 140 from the substrate 210, releases the limit assembly 500, and then switches the present invention to the first change state, such as Figure 1 As shown, the personnel can return to the ground from the sliding plate 220. It should be noted that when the present invention performs high-altitude rescue, the pulley component 700 needs to be electrically powered, that is, the pulley component 700 needs to be added with a pulley motor and a conveyor belt 750; and, when performing high-altitude rescue, the sliding plate 220 needs to be surrounded by a guardrail to prevent the rescued personnel from falling from the sliding plate 220. Finally, the control of each electrical component of the present invention, such as the first motor 201, the adjusting rod motor 330, and the pulley motor, is completed by a controller and a sensor, etc., which are all prior arts and will not be described in detail here.
