Description
Technical field
The present invention relates to a kind of apparatus for demonstrating, particularly a kind of reciprocating descent control device apparatus for demonstrating.
Background technology
In recent years, city developed rapidly, and high building stands in great numbers, and fire also happens occasionally, and how to become the focal issue of present society masses in a fire from eminence escape.Traditional fast-escape mode makes to pass through rope ladder, the facilities such as life chute are escaped, but these facility costs are high, take up room large, use inconvenience, especially the old and the weak is inapplicable, now there is a lot of escaping descent control device in the market, this descending lifeline saving material, reliability are high, high safety, but lack a kind of apparatus for demonstrating of this type of escaping descent control device, can not demonstrate the function of this type of escaping descent control device, using method etc. to popular friend timely.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of reciprocating descent control device apparatus for demonstrating, can explain the application principle of reciprocating descent control device to popular friend easily.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of reciprocating descent control device apparatus for demonstrating, comprise protective housing, the time relay and motor is provided with in described protective housing, the described time relay is connected by wire with motor, described motor side is also provided with fixed pulley, fixed pulley is arranged on the lower end of protective housing by trip bolt, described fixed pulley is provided with rope, the side of described rope is provided with induction disk, described protective housing is also provided with photoelectric induction device, described photoelectric induction device is connected by wire with the time relay and motor, described motor is connected with power supply by wire, described motor is also connected with gauge tap, described protective housing upper end is provided with hooking device.
As preferably, the described time relay and motor are fixed in protective housing by trip bolt, and described motor is connected with fixed pulley bearing.
As preferably, described photoelectric induction device is arranged on the outside of protective housing, receives the signal on induction disk.
The invention has the beneficial effects as follows:
Adopt a kind of reciprocating descent control device apparatus for demonstrating of the present invention, reasonable in design, convenient and practical, control electric machine rotation by photoelectric induction device and the time relay, the effect of descending lifeline being displayed of image, allows audience understand the use procedure of descending lifeline fully.
Accompanying drawing explanation
