Description

Technical Field

[0001] This invention relates to the field of rescue equipment technology, and in particular to a rescue cage used at construction sites. Background Technology

[0002] Stretchers play a vital role in emergency care. They are devices that can safely and conveniently transport the injured and sick, and are suitable for various situations, such as fires, earthquakes, and traffic accidents. The design of stretchers usually takes into account the comfort and safety of the injured and sick, as well as the convenience of transport. In recent years, given the increasingly severe safety situation at construction sites, higher requirements have been placed on the rescue of injured personnel at construction sites and the prevention of secondary injuries to workers.

[0003] In the use of existing rescue equipment, the common method for transporting injured and immobile personnel is to manually carry them on a stretcher. Chinese patent application publication number CN 107496083 A discloses a stretcher cart that can be raised and automatically balanced. However, when the injured person is in a high position in a building, there is also a method of using a hoist to lift and transport the injured person. Obviously, the stretcher cart cannot quickly level itself during the hoisting process. Most of the existing technologies use a simple cage, in which the injured person is placed and secured with straps before being transported.

[0004] However, the hoisting cages currently used for rescue at construction sites do not have an automatic leveling function, which can easily cause secondary displacement of the rescued personnel during the rescue process, resulting in secondary injuries, or even the hoisting cage tipping over, leading to serious accidents such as the rescued personnel falling from a height. Furthermore, the small back-and-forth swaying of the hoisting cage is irregular and does not sway in the left-right or front-back direction. The frequent swaying can cause dizziness in the rescued personnel in the hoisting cage, further increasing their discomfort. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing rescue cages used at construction sites, which pose safety hazards, and to provide a rescue cage for use at construction sites, aiming to solve the problem that rescued personnel may experience discomfort during cage rescue in the process of high-rise building construction.

[0006] The present invention is achieved through the following technical solution: a rescue cage for use at a construction site, comprising a cage body, a leveling device at the bottom of the cage body, and a fixing frame for placing a stretcher at the top of the leveling device; The leveling device includes a rotary motor, and the output end of the rotary motor is provided with a rotating platform; the rotating platform is arranged parallel to the bottom surface of the cage body, and the rotating platform can rotate horizontally; The upper part of the rotating platform is provided with a first driving device. The output end of the first driving device is connected to the fixed frame through a connecting device. The connecting device includes a support structure. The support structure can rotate in the vertical direction. The support structure is connected to the bottom of the fixed frame through a spherical seat.

[0007] Furthermore, the top of the cage body is set as an opening, the four sides of the cage body are provided with protective nets, and the upper part of the cage body is provided with a lifting ring for connecting the lifting device.

[0008] Furthermore, the protective netting along the length of the cage body is provided with double doors, and the bottom plate of the cage body is hinged to a column. When the double doors are closed, they are connected to the column via a pin.

[0009] Furthermore, the bottom of the cage body is provided with multiple sets of universal wheels, and the upper part of each universal wheel is provided with a connecting cylinder that is fixedly connected to the cage body. Each connecting cylinder is provided with a rotary motor, and the rotary motor is connected to the rotating platform above through a connecting shaft.

[0010] Furthermore, the upper part of the rotating platform is higher than the bottom surface of the cage body, and the upper surface of the rotating platform is provided with a mounting column, with the first driving device located on the top of the mounting column.

[0011] Furthermore, the support structure includes a first support rod, one end of which is connected to a reduction gear on the first drive device.

[0012] Furthermore, a second driving device is provided at the end of the first support rod away from the first driving device, a second support rod is provided at the output end of the second driving device, and the other end of the second support rod is connected to the spherical seat.

[0013] Furthermore, the first support rod and the second support rod are arranged on the same vertical plane, and the rotation directions of the free ends of the first support rod and the second support rod are on the same vertical plane.

[0014] Furthermore, the upper surface of the fixing frame is provided with multiple snap-fit ​​holes, and the lower part of the stretcher is provided with snap-fit ​​posts that cooperate with the snap-fit ​​holes.

[0015] Furthermore, the snap-fit ​​post includes a movable post and a fixed post. The upper part of the movable post is hinged to the stretcher. A pressure handle is provided at the top of the movable post. A spring is provided between the movable post and the fixed post. A raised ring is provided on the outer wall of both the movable post and the fixed post.

[0016] The beneficial effects of this invention are as follows: 1. The fixing frame consists of two diagonally intersecting connecting plates. A horizontal connecting plate is set in the middle position and connects to the leveling device in the middle position of the cage body. The cross connection is used. There are standing positions for operators at both ends of the fixing plate to prevent other personnel from stepping on the fixing plate and causing damage due to excessive load, thus improving the use effect.

[0017] 2. By using a rotating platform, the first support rod, and the second support rod to work together in the horizontal and vertical planes, each support point has independent adjustment capabilities, allowing for different adjustments based on varying degrees of tilt.

[0018] 3. The fixed frame and the second support rod are connected by a ball joint, which increases the range of adjustment angle between the fixed frame and the cage body, and improves the comfort of the rescued personnel during the hoisting process.

[0019] 4. The use of six support points to adjust the fixing frame makes it more suitable for maintaining a horizontal position during hoisting. It meets the need for adjustment when the cage body is tilted in different directions, ensuring safety during use. It also realizes the automatic leveling function of the stretcher during hoisting, effectively avoiding secondary displacement and secondary injury of the rescued personnel during the rescue process, and improving the safety and efficiency of the rescue work.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0023] like Figure 1-9 As shown, this invention provides a rescue cage for use on construction sites, mainly comprising a cage body 1, a leveling device 3, a fixing frame 2, and a stretcher 5. The top of the cage body 1 is designed to be open, and protective nets 101 are installed on all four sides, ensuring both ventilation and the ability to observe the condition of the rescued personnel inside, thus ensuring rescue safety. Uprights 103 are fixedly installed at each of the four corners of the cage body 1, and a lifting ring 102 is installed on the upper part of each upright 103 for connecting to a lifting device to realize the lifting, lowering, and transfer of the cage.

[0024] The leveling device 3 is located at the bottom of the cage body 1, and includes a rotary motor 301. The rotary motor 301 is connected to the rotating platform 402 via a connecting shaft, enabling the rotating platform 402 to rotate horizontally. The upper part of the rotating platform 402 is slightly higher than the bottom surface of the cage body 1 to ensure smooth rotation and facilitate the installation of the rotating platform 402. The horizontal rotation of the rotating platform 402 allows adjustment of the angle of the leveling device 3 on the horizontal plane, so that the upper fixing frame 2 can be adjusted to the optimal position to meet the needs of use.

[0025] A mounting column 302 is vertically mounted on the upper surface of the rotating platform 402. A first drive device 303 is fixed to the top of the mounting column 302. The mounting column 302 has a certain height to provide sufficient space for the installation of the first drive device 303. The first drive device 303 provides power to the support structure. The output end of the first drive device 303 is connected to the fixed frame 2 through a connecting device, which includes a support structure that rotates vertically. The support structure consists of a first support rod 304 and a second support rod 306. One end of the first support rod 304 is connected to a reduction gear on the first drive device 303, and the other end is equipped with a second drive device 305. The output end of the second drive device 305 is connected to the second support rod 306, and the other end of the second support rod 306 is connected to the bottom of the fixed frame 2 through a ball seat 307. Both the first drive device 303 and the second drive device 305 are motors. Connecting gears are provided at the drive ends of the first support rod 304 and the second support rod 306. The drive gears are connected to the reduction gearboxes provided on the first drive device 303 or the second drive device 305. The drive gears are provided inside the reduction gearboxes to drive the first support rod 304 and the second support rod 306. This design allows each support point of the fixed frame 2 to be flexibly adjusted in multiple directions under the combined action of the drive devices, thereby quickly reaching a horizontal state and ensuring the stability of the stretcher 5 and the injured person.

[0026] Six support points are provided at the bottom of the cage body 1. Since the cage body 1 is rectangular, the support points are evenly distributed in pairs along the length. The rotating platform 402 can rotate horizontally, and each support point can be adjusted at any angle in the horizontal direction. When the cage body 1 tilts, the downward tilting support point can quickly rotate horizontally to the corresponding angle. Then, the first drive device 303 and the second drive device 305 drive the first support rod 304 and the second support rod 306 to lift upward. A spherical seat 307 is provided at the lower part of the fixing frame 2. When the fixing frame 2 tilts relative to the bottom surface of the cage body 1, it can achieve leveling within a range of 15 degrees. The motor drive enables a rapid response, promptly maintaining the level of the fixing frame 2, improving the comfort of the rescued person on the stretcher 5, and preventing secondary injuries.

[0027] The fixing frame 2 is located on top of the leveling device 3 and is used to place the stretcher 5. The fixing frame 2 consists of two diagonally intersecting connecting plates. A connecting plate is horizontally positioned in the middle and connects to the leveling device 3 in the middle of the cage body 1. There are support points at the front, middle, and rear positions to ensure stability and improve the stability of the stretcher 5. The upper surface of the fixing frame 2 is provided with multiple locking holes 201 that cooperate with the locking posts 501 below the stretcher 5 to achieve stable fixation of the stretcher 5.

[0028] The locking post 501 consists of two parts: a movable post 502 and a fixed post 503. The movable post 502 and the fixed post 503 have semi-circular cross-sections and are positioned opposite each other. The upper part of the movable post 502 is hinged to the stretcher 5, and the upper part of the fixed post 503 is fixedly connected to the bottom of the stretcher 5. A pressure handle 504 is provided at the top of the movable post 502, passing through the stretcher 5 and tilted above it for easy manual operation. A spring 505 is installed between the movable post 502 and the fixed post 503. During use, the person carrying the stretcher 5 presses down on the pressure handle 504, reducing the distance between the movable post 502 and the fixed post 503, making it easier to insert into the locking hole 201. After locking, the pressure handle 504 is released, and the spring 505 pushes the movable post 502 outwards to abut against the inside of the locking hole. Both the movable column 502 and the fixed column 503 have raised rings on their lower outer walls, which further enhances the firmness of the snap-fit, ensures the tightness and stability of the snap-fit, and prevents the stretcher 5 from shifting during transport.

[0029] The bottom of the cage body 1 is also equipped with multiple sets of omnidirectional wheels 4 for easy movement and positioning on the ground. The omnidirectional wheels 4 are fixedly connected to the cage body 1 via a connecting cylinder 401. A rotary motor 301 is installed inside the connecting cylinder 401. This motor is connected to the rotating platform 402 above via a connecting shaft, providing power support to the rotating platform 402. The drive motor is located inside the connecting cylinder 401, saving installation space. The drive motor is vertically mounted inside the connecting cylinder 401 and fixed inside by a frame. The drive battery 403 is located below the drive motor, simplifying the installation structure and providing power to the drive motor, the first drive device 303, and the second drive device 305 above. A control board is installed in the gap between the drive motor and the connecting cylinder 401, enabling quick adjustments and centralizing the installation structure. An inclination sensor is also installed at the bottom of the connecting cylinder 401 or the cage body 1. The support height of the fixing frame 2 is adjusted in time by collecting the inclination angle, so as to achieve the effect of quick judgment and quick action. This greatly improves the comfort of the rescued personnel during the hoisting process and ensures the safety of use.

[0030] In the actual rescue process, the operator first connects the cage body 1 to the lifting device through the lifting ring 102 and lifts it to the location of the injured person. Then, the double doors of the cage body 1 are opened (the double doors are set on the protective net 101 along the length of the cage body 1. When closed, they are connected to the uprights 103 through pins. The uprights 103 are hinged to the side of the bottom plate of the cage body 1. After the double doors are opened, the uprights 103 are laid down outwards to facilitate the stretcher 5 to enter the interior of the cage body 1). The stretcher 5 is placed on the fixed frame 2 and is firmly fixed by the cooperation of the locking post 501 and the locking hole 201. Next, the leveling device 3 is activated, and the rotary motor 301 and the first and second drive devices 305 work together to quickly level the fixed frame 2 through flexible adjustment of the support structure. Finally, the double doors are closed, and the cage and the injured personnel are hoisted to a safe area using the lifting equipment. This realizes the automatic leveling function of the stretcher 5 during the hoisting process, effectively avoiding secondary displacement and secondary injury of the rescued personnel during the rescue process, improving the safety and efficiency of the rescue work, and is suitable for rescue work at construction sites.
