Derrick racking escape device. Oil and gas drilling, workover operations in case of a blowout when, at the risk of fire or other emergency situations winds, can not take advantage of vertical climbing ladder of escape, derrick worker can be installed quickly to escape the danger zone from the high altitude escape through the drilling derrick floor units, safely descend to the ground of the device is suitable for one or more continuous rapid fall to the ground from a height. The main technical indicators: (1) decline in load: ≤130Kg (2) decline in height: ≤100m (3) belt Maximum load: 650Kg (4) Operating ambient temperature: -400C ~ 600C (5) the rate of decline: 0.16 ~ 1.5m / s (adjustable) (6) two-way cable-stayed strength: 650Kg (7) means the total weight: ≤45Kg device components: the governor, the manual controller, ∮10 cable, safety hooks, belts, pull tensioner fastening rope device structure Features: 1, by the governor gear transmission and friction reducer system components, depending on the weight of the user, to achieve balance in a very short period of time, so that the rate of decline steadily. 2, two-story units evacuee adjustable rate of decline through the manual controller, and can start and stop at random according to the actual situation in the air. 3, the device is equipped with seat belts, evacuee in the air without fear, without falling sensation when landing. 4 people can escape the continuous altitude, and back and forth, saving time, and convenient. 5, cable-stayed high strength, safety and reliability.
