Embodiment Construction

[0025] The present invention will be further described below in conjunction with accompanying drawing.

[0026] Such as figure 1 As shown, the large-stroke portable rescue hoist includes a frame plate, a DC geared motor, a worm gear reducer, a pass-through winch, a fall arrest device, a rope clamping device, a handle and a safety hook. The DC gear motor and worm gear reducer are placed on one side of the frame plate to provide power for the whole machine; the pass-through winch is located on the other side of the frame and is the core part of the machine; the rope clamping device and the pass-through winch are located on the same side , to assist the through-type winch to compress the rope; the worm gear reducer and coupling are on the same side as the DC geared motor and above it, connecting the DC geared motor and the through-type winch to provide movement and force transformation for the machine, and take into account the prevention Falling function; the anti-falling devic...

Abstract

The invention relates to a large-travel portable rescue lifter. The traditional rescue equipment has large size and higher price. The large-travel portable rescue lifter comprises a rack board, a DC reducer motor, a worm wheel and worm reducer, a through winch, a falling preventing device, a rope clamping device, a handle and a safety hook, wherein one side of the rack board is provided with the DC reducer motor, and a worm wheel end of the worm wheel and worm reducer is fixedly connected with a main shaft on the other side of the rack board; the through winch is sheathed on the main shaft, and the top of the through winch is provided with the rope clamping device; and the falling preventing device, the handle and the safety hook are also arranged on the rack board. The large-travel portable rescue lifter can realize free lifting up and down so as to achieve dual functions of high-rise rescue and escape.

Description

technical field [0001] The invention belongs to the technical field of mechanical rescue, and relates to a large-stroke portable rescue lifter. Background technique [0002] With the continuous acceleration of industrialization and urbanization in our country, cities have become forests of reinforced concrete, and buildings are built higher and higher, and denser and denser. Although this is a symbol of prosperity, it is precisely because the buildings are too tall and dense that in the event of disasters such as fires and earthquakes, it is increasingly difficult to escape and rescue. Existing data show that fire accidents in high-rise buildings in some developed cities in my country have shown an accelerated upward trend. At present, the ability of fire emergency rescue equipment and the development of high-rise buildings are seriously out of balance. The highest lifting capacity of aerial ladder trucks is only about 15 floors. These equipment are often bulky and poor in ...
