Embodiment 1

[0031] In this embodiment, the permanent magnet adopts internal sintered NdFeB magnet N52, the surface magnetism is 15000GS, and the permanent magnet is wrapped with a 304US stainless steel layer, which can reduce the influence of heat on the magnetic field. The temperature resistance can reach 400 ° C, and the length of the permanent magnet is 55mm.

[0032] The coil is made of T2 red copper wire with a diameter of 0.5mm, the diameter of the coil is 15mm, the length of the coil is 40mm, and the number of turns of the coil is 80.

[0033] The outer diameter of the sleeve is 150 mm, the inner diameter is 127.5 mm, and the length is 347.5 mm.

[0034] The outer diameter of the inner cylinder is 125mm, the length of the inner cylinder is 302.5mm, the inner diameter of the circular grooves opened at both ends of the inner cylinder to accommodate the connecting sleeve is 95mm, the depth is 45mm, the inner diameter of the inner cylinder is 75mm, and the upper three The spacing betwe...

Abstract

The invention discloses an electromagnetic and frictional damping descent control device. A sleeve is arranged between two side baffles, an inner cylinder is arranged in the sleeve, a long-strip-shaped permanent magnet is arranged in the inner cylinder, and the inner cylinder moves left and right in the sleeve along the permanent magnet; and a rescue strap used for fixing a user is installed on a first screw rod, a manual emergency stop device is installed on second screw rods, a steel cable is wound on the outer wall of the sleeve, one end of the steel cable is fixed to the outer wall of the sleeve, and the other end of the steel cable penetrates through a through hole of the manual emergency stop device and then is fixed through a hook. Through cooperative work of various dampers, slow descent is more stable, high-altitude stable and safe slow descent of a human body can be achieved, manual adjustment and control of a user are not needed, and the descent control device is simple in structure, convenient to use, capable of being correctly used without training, capable of playing a great role in rescue work of trapped persons in a high layer, capable of being used as a fire fighting machine, and wide in application prospects.

Description

technical field [0001] The invention relates to the technical field of fire fighting equipment, in particular to an electromagnetic and frictional damping slow down device. Background technique [0002] With the development of cities, high-rise buildings are ubiquitous. In the event of fire and other disasters, casualties often occur. It is necessary to strengthen emergency handling and self-rescue, thereby reducing or even avoiding the occurrence of casualties. The rescue method that generally adopts at present is to rescue by equipment such as escape slide rail, parachute, life-saving descending device. [0003] In practical application, when using the existing descending device to escape from a high-rise window, the user is required to be trained in the method of use or have certain professional knowledge to adjust and control the descent speed. However, for old people and children, it is more difficult to master the slow-descent technology in a short time. Therefore, it...
