Description

A kind of elevator safety device

Technical field

This utility model belongs to technical field of elevator equipment, is specifically related to a kind of elevator safety device.

Background technology

Elevator is a kind of vertical conveyor with motor as power, has box like gondola inside it, takes advantage of people or carrying goods for tier building.Elevator is the vertical transport instrument of the modern material progress of mark, is electromechanical integration instrument, is the complex transportation equipment of electromechanical integration, it relates to electronic technology, mechanical engineering, Power Electronic Technique, microcomputer technology, electric power torr moves multiple scientific domain such as system and civil engineering.

One of the condition of production of current elevator and the usage quantity mark having become as modernization of the country degree, along with the high development of modern city, have major pedestrian movement and logistics to need conveying every day.For saving the area and adapting to economy and trade career development, a flickering high building is rised sheer from level ground, and the vertical transport of these skyscrapers is an outstanding problem, is closely related with the live and work of people.

The handrail of existing vertical lift internal Protection equipment, hand draw ring on market, level of security is low, and protection dynamics is little, it is impossible to effectively protecting for concrete crowd, motility is low.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art and provide a kind of elevator safety device, and this device efficiently solves elevator operating not in time of passenger and injury of causing during declining, and simple in construction, easy to operate.

In order to achieve the above object, this utility model adopts the following technical scheme that

This utility model provides a kind of elevator safety device, and including car and car door, the car inwall of the left and right sides of described car door is provided with U-shaped draw-in groove, and draw-in groove is symmetrical, and horizontal symmetry is high, medium and low multipair.Respectively setting 35 mobile draw rings on cross bar, high bar is for being 2.3 2.4m between distance cage bottom, and the distance in cross bar and between the bottom of car is 2.2 2.3m, and the distance between the low bar of cross bar and the bottom of car is 2.1 2.2m.The medial wall of the car corresponding with described car door is provided with two-way or positive and negative inductive switch, the top outer of car is provided with motor, motor electrically connects with induction bidirectional or positive and negative switch, top on the upside of car is provided with faking device and pulley, the power intake of faking device is connected or integrated connection with the output of motor, the outfan of the rope on faking device strides across pulley and arranges, and the outfan of rope is provided with hand draw ring.

According to above-mentioned elevator safety device, described motor is fixedly installed on outside car by support of motor and faking device or top, depending on scene.

According to above-mentioned elevator safety device, described cross bar high with cross bar in and low fixed by the U-shaped draw-in groove left and right sides of support respectively.

According to producing needs, the U-shaped draw-in groove on car medial wall can arrange multipair, and cross bar arranges many, depending on concrete cross bar and U-shaped pocket numbers and height space size scene.

Compared with prior art, the beneficial effect that this utility model obtains:

1, in this utility model structure, the car roof of the left and right sides of car door has many cross bars, high 2.3 2.4m of cross bar, 2.2 2.3m in cross bar, low 2.1 2.2m of cross bar.Different safety prevention measures is used according to the regulation of passenger height, cross bar height is grabbed as 1.8 meters of the above persons enter car hands, 1.70 1.5 meters of personnel find draw ring or the cross bar being suitable for height after entering elevator, the personnel of less than 1.5 meters enter elevator and press positive and negative or bidirectional inductive switch on the other hand, allowing draw ring drop to suitable height, another pulls draw ring of stopping.

2, this utility model simple in construction, reasonable in design, has broad application prospects.

Accompanying drawing explanation

Fig. 1 is this utility model structural representation.

Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is further illustrated.

nullWith reference to shown in Fig. 1，A kind of elevator safety device，Including car 1 and car door 2，Cross bar 13 and cross bar 114 it is provided with in the car of the left and right sides of described car door 2，Cross bar 13 and cross bar 114 are removably disposed on the car inwall of the left and right sides by bracing frame respectively，Cross bar 13 is all parallel with the bottom of car 1 with cross bar 114，And it is equipped with 13 pairs of draw rings 5 on cross bar 13 and cross bar 114，Distance between the bottom of cross bar 13 and car 1 is 2.3 2.4m，Distance between the bottom of cross bar 114 and car 1 is 2.2 2.3m，The medial wall of the car 1 corresponding with described car door 2 is provided with two-way positive and negative switch 6，The outside at the top of car 1 is provided with motor 7，Motor 7 is fixedly installed on the lateral wall of car by support of motor，Motor 7 electrically connects with inductive switch 6，Top outside car 1 is provided with faking device 8 and pulley 9，The power intake of faking device 8 is connected with the output shaft of motor 7，The outfan of the rope on faking device 8 strides across pulley 9 and arranges，The outfan of rope is provided with hand draw ring 10，Wherein said rope is steel wire rope，Pulley 9 is fixed pulley.

Operation principle of the present utility model

Enter in lift car 1 according to different height passengers, 1.8 meters of the above persons enter car 1 hands and grab the draw ring on cross bar 13, 1.7 meters of the above persons grab the draw ring on cross bar 114 after entering car 1, 1.7 1.5 meters of personnel find, after entering elevator, the draw ring being suitable for height, less than 1.5 meters personnel switch 6 by upper positive and negative bidirectional inductive in entering lift car on the other hand, above allowing, at pulley 9, hand draw ring drops to proper height, another pulls draw ring of stopping, press positive and negative both sides' inductive switch 6 when passenger leaves and automatically shrink steel wire rope hand draw ring, more than operation needs to complete in strict accordance with normal operating flow process, prevent elevator from operating not in time during declining and coming to harm.
