Escapement transmission type high building escape device

Abstract

The invention provides an escapement transmission type high building escape device. The device comprises a fixing support, a main shaft, a winding drum, a steel wire rope, a ratchet wheel mechanism, an escapement mechanism, a ball bearing and a small chain wheel shaft. The two ends of the main shaft are supported and positioned to the fixing support. The ball bearing and a pawl base are mounted onthe main shaft in a sleeving manner. The two ends of the winding drum are fixedly and coaxially connected with the outer race of the ball bearing and a ratchet wheel correspondingly. The steel wire rope is wound on the outer side of the winding drum. The escapement mechanism comprises a first shaft, a second shaft, an escapement wheel, an escapement fork, a support and a balance wheel. The firstshaft is rotationally supported on the fixing support and located on the lateral side of the main shaft. A gear transmission mechanism is arranged between the first shaft and the main shaft. An escapement transmission mechanism is arranged between the first shaft and the second shaft. The escapement wheel is mounted on the first shaft in a sleeving mode. The escapement fork is mounted at the firstend of the second shaft in a sleeving mode. The other end of the second shaft is sleeved with the balance wheel. According to the escapement transmission type high building escape device, the gravitational potential energy of a human body is uniformly released by means of alternating engagement of the escapement wheel and the escapement fork, so that the human body falls at a certain uniform speed, thereby guaranteeing that the human body lands safely.

Description

technical field [0001] The invention relates to an escape device, in particular to an escapement transmission type high-rise escape device. Background technique [0002] The escapement mechanism is a special form of the ratchet mechanism, which also belongs to the intermittent motion mechanism, and is mainly used in timers and timers. The escapement mechanism is mainly composed of an escape wheel and a pallet fork. The escape wheel has a power source (such as a spring spring, a torque generated by gravity, etc.), and always has a tendency to rotate in one direction. The pallet fork also has its own power source, such as a balance balance or hairspring, which makes it reciprocate. Escapements come in many different structural forms, but the basic principles are the same. [0003] Although the escapement mechanism is widely used in timing mechanisms such as clocks and watches, the force of the timer is relatively small, and it is rarely used in other aspects, especially the ...

AI Technical Summary

Problems solved by technology

[0003] Although the escapement mechanism is widely used in timing mechanisms such as clocks and watches, the force of the timer is relatively small, and it is rarely used in other aspects, especially the occasions with a large load. There are few materials introducing the structural design of the pendulum escapement mechanism.
