By repeatedly pressing the handle down, the long rack The rack is lifted as a whole and gradually makes the flat plate fit above the windowsill. At this time, the staff rotates the disc to make the disc drive the threaded rod to rotate forward. While the threaded rod rotates forward, it gradually pushes the clamping plate to move toward the inside of the flat plate. By continuously rotating the disc, the clamping plate gradually approaches the fixed block, and the top of the windowsill is clamped by the fixed block and the clamping plate. Then the buckle block is rotated to buckle the buckle block on the threaded rod to prevent the threaded rod from slipping and loosening, thereby achieving two support points, improving the stability of the lifting bracket, facilitating rapid support according to different sizes of windowsills, and being able to clamp the top of the windowsill strongly to prevent the support rod from slipping during rescue, thereby improving the safety of the fire rescue lifting bracket.
[0023] 2. The utility model installs a rescue rope in a micro electric hoist and places one end of the hoist on a cylinder. Then the staff uses the rope to descend for rescue. When the staff is shaken by the influence of the wall, the rope vibrates. Then the force generated by the vibration is transmitted to the surface of the cylinder through the rope. The vibration generated by the rope is damped and buffered by the cooperation of multiple dampers, thereby reducing the amplitude of the vibration generated by the staff during the rescue. This prevents the rescuers hanging in the air from swaying when they use the lifting bracket for descending, avoids the rope from shaking continuously, and dampens the rope as a whole, thereby improving the practicability of the window sill lifting bracket for fire fighting and rescue.

[0035] In this embodiment, a rescue rope is installed in a micro electric hoist 201, and one end of the rescue rope is placed on a cylinder 203. The staff then uses the rope to perform a descent rescue. When the staff is shaken by the influence of the wall, the rope vibrates. The force generated by the vibration is transmitted to the surface of the cylinder 203 through the rope. The vibration generated by the rope is damped and buffered by the cooperation of multiple dampers 204 and spring 205, thereby reducing the amplitude of the vibration generated by the staff during the rescue. This prevents the rescuers suspended in the air from swaying when they are using the lifting bracket for descending, avoids the rope from shaking continuously, and dampens the rope as a whole, thereby improving the practicability of the fire-fighting and rescue window sill lifting bracket.
[0036] Working principle: When in use, the staff first installs the base plate 1 on the required rescue window sill, and then pulls the handle 115 downward, and the handle 115 drives the semicircular gear 114 to rotate. The rotation of the semicircular gear 114 drives the long rack 102 to move upward. As the long rack 102 moves upward, the teeth on the surface of the limit plate 116 will be snapped into the teeth of the long rack 102 to prevent the long rack 102 from sliding downward. The limit plate 116 is pushed by the spring 118 to tilt the limit plate 116 as a whole, and the teeth on the surface of the limit plate 116 are firmly snapped into the teeth of the long rack 102. At this time, the staff pulls The handle 115 is moved to the rear end of the groove 112, and then the handle 115 is pulled upward to reset the semicircular gear 114, and then the handle 115 is pushed to make the semicircular gear 114 mesh with the teeth of the long rack 102 again, and then the handle 115 is pressed down again. By repeatedly pressing down the handle 115, the long rack 102 is lifted as a whole, and the flat plate 103 is gradually attached to the top of the window sill. At this time, the staff rotates the disc 109, so that the disc 109 drives the threaded rod 108 to rotate forward, and the threaded rod 108 gradually pushes the clamping plate 106 to move toward the inside of the flat plate 103 while rotating forward. By continuously rotating the disc 109, the clamping plate 106 gradually approaches the fixing block 104, and the fixing block 104 and the clamping plate 106 are used to clamp the top of the windowsill. Then the buckle block 110 is rotated to buckle the buckle block 110 on the threaded rod 108 to prevent the threaded rod 108 from slipping and loosening, thereby having two supporting points, improving the stability of the lifting bracket, facilitating rapid support according to different sizes of windowsills, and being able to clamp the top of the windowsill strongly to prevent the support rod from slipping during rescue, thereby improving the safety of the fire rescue lifting bracket. The staff installs the rescue rope in the micro electric hoist 201 and puts one end of it in It is placed on the cylinder 203, and then the staff uses the rope to descend for rescue. When the staff is shaken by the wall, the rope vibrates, and then the force generated by the vibration is transmitted to the surface of the cylinder 203 through the rope, and the vibration generated by the rope is damped and buffered by the mutual cooperation of multiple dampers 204 and springs 205, thereby reducing the amplitude of the vibration generated by the staff during the rescue, thereby preventing the rescuers hanging in the air from swaying when the rescuers use the lifting bracket to descend, avoiding the rope from shaking continuously, and damping the rope as a whole, thereby improving the practicability of the fire-fighting and rescue window sill lifting bracket.
