Specifically, the energy absorption structure comprises an energy absorption sleeve, a shock absorption rod and a shock absorption pad. Energy-absorbing sleeve, shock absorber pole are the high strength steel, the energy-absorbing sleeve sets up on the landing slab 201, the top of shock absorber pole sets up in the energy-absorbing sleeve, the top of shock absorber pole with the energy-absorbing sleeve constitution confined space. The shock pad sets up the bottom of shock-absorbing rod, the bottom of support post 400 also is provided with the shock pad that matches, the shock pad is elastic rubber pad, prevents the shock-absorbing rod with floor 100 hard collision. The upper part of the platform plate 201 is close to one side of the support upright 400, and a pedal 211 for emergency escape is arranged between the left support bracket 202 and the right support bracket 203.

The footboard 211 is connected with the top of support post 400 through blocking structure 210, blocking structure 210 sets up that one side that the landing slab 201 is close to support post 400, blocking structure 210 includes dog 211, a pair of locking couple 212, footboard 213, footboard spring, footboard pivot, couple connecting rod, separation connecting rod 214, the dog sets up on the boss of the support post 400 top left and right sides, the top of dog 212 is provided with the arch, the bellied bottom of dog 212 sets up to semi-circular, the bellied top of dog 212 sets up to the plane. The stop hook 213 is disposed at a position on the platform plate 201 matching with the stopper 212, and the stop hook 213 is connected through a hook connecting rod to form a linkage structure. Stop couple 213 includes ejector pin, branch, stop couple's ejector pin and branch junction are provided with rotatory hole, stop couple 213 is through running through the rotatable setting of couple pivot in rotatory hole is in on the landing slab 201 and branch stretches out landing slab 201, the top that branch stretches out is provided with semi-circular arch, and the bottom sets up to the plane, the ejector pin is up. Due to the structural design, the stop hook 213 can be better blocked by the stop block in the initial state, and when the lifting platform 200 is reset, the stop hook can rotate, so that the stop hook is prevented from being clamped. Footboard 211 passes through the rotatable setting of footboard 211 pivot and is in on the landing slab 201, footboard 211 is provided with the protruding arch of landing slab 201 bottom surface. The pedal 211 is disposed between the pedal 211 and the platform plate 201, and the pedal 211 is lifted up in an initial state. The separation link 214 connects the protrusion of the step 211 with the top bar of the stopper hook 213.

In the initial state, the lifting platform 200 is pulled upward by the wire rope 323 of the slow-descent brake governor 320 and positioned in the rectangular frame, and at this time, the support rod of the stopper hook 213 is caught by the stopper 212. When a person goes up the lifting platform 200, the spring of the pedal 211 is compressed under the gravity of the person and the lifting platform 200, but the stop hook and the stop block are not separated yet. When a person stands on the lifting platform 200 stably, the pedal 211 is stepped on violently, the spring of the pedal 211 is further compressed, the support rod of the stop hook 213 is driven by the separation connecting rod to rotate upwards, and then is separated from the stop block, the weight of the lifting platform 200 and the weight of the escaper 500 are larger than that of the balancing weight, and the lifting platform 200 slides downwards.
