[0038] Reference Figure 1 、 Figure 3 、 Figure 4 、 Figure 7 and Figure 8 , a transfer vehicle with an automatic stretcher device according to an embodiment of the present invention comprises: a vehicle body 1, a dragging mechanism 6 and a stretcher transfer mechanism 7;
[0039] The stretcher transfer mechanism 7 includes a stretcher body 71, a transfer rail 72, and a transfer power assembly. The transfer rail 72 is provided on the vehicle body 1. The stretcher body 71 is provided on the vehicle body 1 and is movably connected to the vehicle body 1 via the transfer rail 72. The transfer power assembly is provided on the vehicle body 1 and located at the bottom of the stretcher body 71. The transfer power assembly enables the stretcher body 71 to move backward from a horizontal position at the rear of the vehicle body 1 to an inclined position in which its rear end contacts the ground and its front end connects to the vehicle body 1. The transfer rail 72 ensures linear movement of the stretcher body 71 and cooperates with the transfer power assembly at the bottom of the stretcher body 71 to achieve two-dimensional movement of forward and backward lifting and lowering.
[0040] The towing mechanism 6 includes a towing rope 61, a towing hook 62, a fixed pulley 63 and a towing power assembly 64; the towing power assembly 64 is arranged on the vehicle body 1, and the fixed pulley 63 is arranged at the front end of the stretcher body 71. One end of the towing rope 61 is connected to the towing power assembly 64, and the other end thereof passes around the fixed pulley 63 and is connected to the towing hook 62 and extends toward the rear of the vehicle body 1.
[0041] Reference Figure 5 Some improved solutions of the present application further include a locking mechanism 9, which includes a base 91 and a locking rod 92. The rear end of the stretcher body 71 is provided with a limit plate 714 protruding toward the side, and the limit plate 714 is provided with a limit hole extending vertically. The base 91 is provided at the rear portion of the vehicle body 1. The locking rod 92 extends in the vertical direction and is movably connected to the base 91. When the stretcher body 71 is in the horizontal position, the locking rod 92 moves downward to pass through the limit hole to limit the stretcher body 71. When the stretcher body 71 is in the horizontal position, it can be limited to the position of the stretcher body 71, ensuring that the stretcher body 71 does not accidentally slide or fall during transportation. This improves safety and avoids unexpected situations that may occur during transportation.
[0042] Some improvements of the present application include a tailgate 82. The stretcher body 71 is surrounded by guardrails 711 on all four edges. The guardrails 711 are provided with an entrance 712 on one side facing the rear of the stretcher body 71. The tailgate 82 is located at the entrance 712, and the lower end of the tailgate 82 is hinged to the rear end of the stretcher. The guardrails 711 surrounding the stretcher body 71 ensure the safety of the injured person. The hinged design of the tailgate 82 allows for flexible opening and closing, allowing it to be opened when needed. When the rear end of the stretcher body 71 touches the ground, the tailgate 82 tilts downward to connect with the ground, forming a slope, making it easier for the injured person to move onto the stretcher body 71 and increasing ease of use.
[0043] In some improved solutions of the present application, guide members 821 are provided on the left and right sides of the tailgate 82, respectively. The rear end of the vehicle body 1 is provided with guide wheels 11 located on the left and right sides of the stretcher body 71. The guide members 821 cooperate with the guide wheels 11 to rotate the tailgate 82 relative to the stretcher body 71 to a position that closes the entrance 712. When the limit plate 714 on the stretcher body 71 slides under the locking rod 92 of the locking base 91 via the guide wheels 11, the locking rod 92 descends and inserts into the limit hole of the limit plate 714. Simultaneously, the guide wheels 11 contact the guide members 821 on both sides of the tailgate 82, driving the tailgate 82 to rotate around its lower end, thereby completing automatic closing.
[0044] In some improved solutions of the present application, the stretcher transfer mechanism 7 further includes a sliding plate 74 and two transfer rails 72. The two transfer rails 72 are respectively provided on the left and right sides of the stretcher body 71. The left and right sides of the sliding plate 74 are respectively slidably connected to the two transfer rails 72, and the rear end of the sliding plate 74 is hinged to the front end of the stretcher body 71. The stretcher body 71 is rotatably connected to the sliding plate 74 by the hinge connection, so that when the stretcher body 71 moves to protrude rearward from the vehicle body 1, it can tilt downward, changing from a horizontal position to an inclined position, with the rear end touching the ground.
[0045] Reference Figure 6In some improved solutions of the present application, the front and rear ends of the transfer track 72 are each provided with upwardly projecting stoppers 721 to limit the movement distance of the sliding plate 74 on the transfer track 72, effectively preventing the stretcher body 71 from exceeding the range of the transfer track 72 during movement, further enhancing safety. At the same time, positioning portions 741 can be provided on the left and right sides of the sliding plate 74, and positioning members 15 can be provided at corresponding front and rear positions of the vehicle body 1. When the sliding plate 74 drives the stretcher body 71 forward to a horizontal position, the front positioning member 15 locks the positioning portion 741, limiting the movement of the sliding plate 74. When the sliding plate 74 drives the stretcher body 71 backward to an inclined position, the rear positioning member 15 locks the positioning portion 741, limiting the movement of the slide plate. This prevents the sliding plate 74 from causing unnecessary displacement of the stretcher body 71 during travel of the vehicle body 1 or when dragging a casualty.
[0046] In some improved schemes of the present application, the transfer power assembly includes a power rolling wheel 73, which is arranged at the rear end of the vehicle body 1 and at the bottom of the stretcher body 71. The bottom of the stretcher body 71 is provided with a guide rail 713 extending along the front-to-back direction. The power rolling wheel 73 is transmission-connected to the guide rail 713. The guide rail 713 includes a first sub-rail 7131 and a second sub-rail 7132 connected in sequence along the front-to-back direction. The first sub-rail 7131 is arranged parallel to the stretcher body 71, and the second sub-rail 7132 is inclined from front to back in a direction away from the stretcher body 71.
[0047] Reference Figure 9 In some improved solutions of the present application, the stretcher body 71 is provided with a limit portion 716 on the left and right sides, and the rear end of the vehicle body 1 is provided with a limit groove 13 adapted to the limit portion 716. The limit groove 13 extends in the horizontal direction, and the limit portion 716 and the limit groove 13 are used to limit the movement of the stretcher body 71 along the front and rear directions and the up and down directions of the vehicle body 1.
[0048] In some improved solutions of the present application, two suspension plates 14 extend downward from the bottom of the vehicle body 1. The two suspension plates 14 are respectively arranged on the left and right sides of the stretcher body 71. The suspension plates 14 have limiting mechanisms 141 protruding toward the stretcher. The limiting mechanisms 141 abut against the stretcher body 71, effectively limiting the left and right swinging of the stretcher body 71 and facilitating the engagement of the limiting plates 714 on both sides of the stretcher body 71 into the locking mechanism 9. Specifically, the limiting mechanisms 141 can be universal ball bearings mounted on the suspension plates 14, which limit the left and right swinging of the stretcher body 71 by limiting the left and right movement of the second sub-rail 7132.
[0049] In some improvements of the present application, a fixing portion 717 is provided at the rear of the stretcher body 71, and the towing hook 62 is detachably connected to the fixing portion 717. The rear of the stretcher body 71 is the rear portion of the stretcher body 71, and the towing hook 62 is temporarily fixed to the rear portion. When the patient is transported, the patient can take the towing hook 62 from the rear portion of the stretcher body 71 near the patient and hang it on the shoulder strap.
[0050] Reference Figure 2 and Figure 3 The usage method of this application is as follows: after the transfer vehicle accurately stops next to the injured person, the transfer power component drives the stretcher body 71 to move toward the rear of the vehicle body 1, and the stretcher body 71 gradually protrudes from the rear end of the vehicle body 1 and moves in a downward inclined direction until the tailgate 82 touches the ground; the towing hook 62 located at the rear end of the stretcher body 71 is hung on the shoulder strap worn by the injured person, and the towing power component 64 is started to drag the injured person onto the stretcher body 71, and the transfer power component drives the stretcher body 71 to be retracted onto the vehicle body 1, and at the same time the tailgate 82 is automatically closed to complete the rescue and transfer of the injured person.
[0051] In summary, the embodiment of the present invention provides a transfer vehicle with an automatic stretcher device, whose towing mechanism 6 and stretcher transfer mechanism 7 can realize linear and lifting two-dimensional movement of the stretcher body 71, and at the same time cooperate with the locking mechanism 9 to automatically lock the stretcher body 71 and close the tailgate 82; the utility model has high rescue efficiency, can fully protect the wounded during transportation, and uses the towing mechanism 6 to assist in quickly and efficiently assisting the wounded to get on the stretcher. The process does not require the cooperation of other personnel, and completely realizes unmanned operation, which has significant practical value.
[0052] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
