An elevator capable of accommodating emergency stretcher vehicles

Abstract

The invention relates to a lift capable of accommodating a first-aid stretcher, which comprises a lift car, a tail compartment, a counterweight housing and a traction mechanism, the back of the lift car is provided with an opening, the tail compartment with a certain accommodation space is arranged at the opening of the lift car, and power is supplied by the traction mechanism; after the tail compartment is fitted on the lift car, the distance from a lift door to the back of the tail compartment is greater than the length of the first-aid stretcher, the counterweight housing is mounted on the left side or right side of a lift shaft or the left, middle and back sides of the back of the lift shaft, and comprises a plurality of counterweight blocks, and each counterweight block is of a high-density narrow structure. When the lift is used, the first-aid stretcher can be used for high-rise first aid.

Description

technical field [0001] The invention relates to an elevator capable of accommodating an emergency stretcher, in particular to an elevator capable of accommodating an emergency stretcher in cooperation with a conventional elevator car and a tail box. Background technique [0002] With the rapid development of science and technology, the improvement of human living standards is constantly changing. Elevators are the only major equipment for vertical transportation in buildings. People have more and more functional requirements for elevators. Existing elevators are far from being able to adapt to today's society. The needs of development, with the continuous improvement of human health and the continuous increase of life expectancy, the number of elderly people will increase. The health problems of the elderly have become the focus of human society, and their medical first aid has become a part of people's daily life. However, in dense residential buildings, the traditional res...

Problems solved by technology

However, the length of the emergency bed or stretcher with medical emergency function is about 1900mm. The disadvantage is that the emergency bed or stretcher cannot be put into the general passenger elevator car with a rated load of 1000kg or 800kg, unless the elevator car The depth dimension is increased to more than 1900mm. Some places are issuing some local regulations on the civil engineering design and procurement of elevators. It is stipulated that the depth of the elevator car must reach 2100mm so that stretchers can be placed. In order to reach the car depth of 2100mm, it is recommended to design rated The load capacity is not less than 1000kg, which causes some buildings to actually only need an elevator with a rated load capacity of 800kg. In order to achieve the purpose of placing the stretcher, the rated load capacity has to be increased

[0006] Unless the depth of the car is increased to 1.9m, the elevator needs to be made into a slender strip, which is more inconvenient for the conventional use of the elevator car shape, which will inevitably cause serious deviations in the plane dimensions of the civil engineering well of the elevator from the conventional, and the civil engineering The area of ​​the hoistway will be seriously increased, which will waste the civil construction area and directly increase the cost of use. Here, there will be a contradiction between the need for use and the area of ​​the elevator car that is strictly not allowed to exceed the standard, and the balance problem is not easy to grasp

[0007] The area of ​​the elevator shaft of the existing building has been determined, and the elevator model and specification have been determined. If the existing elevator needs to be replaced in a large scale, the cost will inevitably be high. If the existing elevator shaft and elevator model Under the condition that the specifications remain unchanged, it is an urgent problem to be solved to develop a solution to realize the first aid of the medical stretcher
