Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-4, a kind of fall arrest Underwell rescue device, including rescue rope 1 are please referred to, the outer cover of rescue rope 1 is equipped with drive Dynamic case 2, the front of driving box 2 are provided with safety belt 8, and the seat plate of protrusion is provided on the driving box 2 immediately below safety belt 8 19, it is pasted with resilient cushion 20 on seat plate 19, facilitates rescue on resilient cushion 20 by rescue personnel 8 recoils that fasten one's safety belt；? The inside of driving box 2 is fixedly mounted there are two idler wheel 3 is mutually overlapped, and two idler wheels 3 are slidably connected with rescue rope 1, generally use Rescue rope and rescue idler wheel coefficient of friction generally between 0.1-0.3, driving machine is able to drive the object of 300kg weight It moves up and down on rescue rope, and passes through transmission belt 4 and the servo for being located at 2 intracavity bottom of driving box on the driving wheel of idler wheel 3 Turntable transmission connection on motor 5, idler wheel 3 can rotate when servo motor 5 rotates, and utilize idler wheel 3 and rescue rope 1 in this way Frictional force can be such that driving box 2 rises or falls, and holder 6, driving box 2 are placed on the driving box 2 of 5 side of servo motor Bottom end enabling 22 is hinged with by blinds 23, facilitate the article taken out in holder 6, a little battalion can be placed using holder 6 The product of supporting etc. guarantee by the physical strength of rescue personnel；The top of holder 6 is provided with for providing the battery of electric energy to servo motor 5 7, battery 7 can carry out electric energy supplement by extraneous power supply, and the switch for controlling electric energy is provided on driving box 2, guarantee quilt Rescue personnel can independently use, while can also add the opening and closing that remote control apparatus carrys out control circuit, can be with by servo motor 5 It drives idler wheel 3 to be risen with respect to rescue rope 1, can quickly be rescued away victim with the cooperation of safety belt 8.

The top of driving box 2 is fixedly connected with the baffle 9 being inserted into cage plate 10, and is overlapped with position in the side of baffle 9 In the deceleration column 12 in cage plate 10, deceleration column 12 is elasticly connected with retarding spring 11 far from the side of baffle 9, when baffle 9 and set When plate 10 separates, deceleration column 12 can be pushed out under the action of retarding spring 11 and block with rescue rope 1, slow down the speed of decline； The upper surface of cage plate 10 is by being sleeved on the buffer spring 13 outside rescue rope 1 and 14 elastic connection of grip block, two groups of grip blocks By 18 elastic connection of limit spring between 14 top, guarantee the relative position between grip block 14, the inner wall of grip block 14 It is provided with anti-slip protrusion 21, prevents that slipping phenomenon occurs in clamping；Grip block 14 is divided to two groups to be clamped in 1 outside of rescue rope, and It is hinged by limit deck 16 between every group of grip block 14, clamping ball 17,14 top of grip block are installed between grip block 14 Inner wall be fixedly connected by steel wire 15 with clamping ball 17, and the other side for clamping ball 17 passes through the top of steel wire 15 and driving box 2 End is fixedly connected, and when driving box 2 runs out of steam unexpected decline, baffle 9 can be separated with deceleration column 12, and such deceleration column 12 can block Firmly rescue rope 1 slows down, and drives steel wire 15 to tense when the decrease speed of driving box 2 reaches certain speed, and then make to clamp Ball 17, which is pulled, indirectly makes grip block 14 clamp rescue rope 1, to play the purpose of fall arrest, guarantees the success rate of rescue.

Ball 17 can be made to clamp when steel wire 15 is tightened up to the Slideslip far from rescue rope 1, in this way due to grip block 14 The gap of tail portion is less than the gap between 1 side of rescue rope, and clamping ball 17 plays the role of a balance pivot, can make Two 14 tops of grip block clamp rescue rope 1, while the tension of steel wire 15 can also be such that 14 top of grip block inwardly moves, and also function to folder Tight purpose, playing clamping rescue rope 1 in tenesmus in this way prevents the purpose of tenesmus, especially when idler wheel 3 can not be with rescue rope 1 When accident occurs for clamping, safety is higher.

In conclusion the fall arrest Underwell rescue device, by servo motor 5 can drive idler wheel 3 with respect to rescue rope 1 into Row rises, and can quickly rescue away victim with the cooperation of safety belt 8.

When driving box 2 runs out of steam unexpected decline, baffle 9 can be separated with deceleration column 12, and such deceleration column 12 can be blocked Rescue rope 1 slows down, and drives steel wire 15 to tense when the decrease speed of driving box 2 reaches certain speed, and then makes to clamp ball 17 be pulled indirectly make grip block 14 clamp rescue rope 1, to play the purpose of fall arrest, guarantee rescue success rate, solve Existing rescue rope 1 is difficult to provide effective rescue service, simultaneously in rescue especially for stranded more long victim The problem of lacking effective anti-drop function when victim declines suddenly in rescue.
