Abstract

The utility model relates to a traction lifting device for a three-dimensional garage, which is mainly characterized in that a carrier bar of a garage frame is fixedly provided with traction machines and six supporting seats with one or two guide wheels. After the traction machines are extended out of both ends of output shafts in the traction machines, traction wheels are installed. Four corners of a cage, which are arranged in the garage frame, are fixedly connected with four groups of traction ropes, and leading out ends of the traction ropes are connected with counterweights via the guide wheels and the traction wheels. The traction ropes are horizontally under stress via the traction machines, spaces between the two traction wheels are big, and the traction ropes are fixedly connected with the four corners of the cage, so the utility model has the advantages of simple structure, low cost, high safety factor and low energy consumption. Traction capacity is improved and the cage moves stably.

Description

A kind of traction lifting appliance that is used for multi-storied garage

The utility model belongs to E04H class technology, particularly relates to a kind of traction lifting appliance that is used for multi-storied garage.

Present known vertical-lifting multi-storied garage, the traction lifting appliance that adopts has two kinds mostly, the vertical traction of the first, promptly the end by the hoist ropes in traction machine and these devices that structure constituted such as traction sheave directly links to each other with car, the other end connects counterweight and identical with the kind of drive of elevator, therefore having deficiency is that power consumption is high, and traction capacity is poor; Safety factor is not high yet, and the traction hoisting velocity can not be very high.It two is that the traction form adopts motorized pulleys, and hoist ropes connects car by motorized pulleys and links to each other with counterweight for four jiaos again, and its existing deficiency is that cylinder needs length long, and difficulty of processing is big, brings the cost costliness thus.

The purpose of this utility model be to overcome the deficiency in the known technology and when a kind of hoist ropes is provided by traction sheave the traction direction be horizontal direction to have a cost low, the traction lifting appliance that is used for multi-storied garage is hanged down in big and good stability of safety factor and power consumption.

The purpose of this utility model is achieved in that

Keeping at a certain distance away on the carrier bar on the garage frame installs 6 supporting seats, installs following two guide wheels on 4 supporting seats therein respectively; On two supporting seats therein 1 directive wheel is installed respectively.On carrier bar, also install traction machine, install the ac variable frequency speed regulation motor on the traction machine again, after traction machine is stretched out at the two ends of the output shaft of installing, a traction sheave is installed respectively on it in traction machine.Can place four jiaos of 4 groups of hoist ropes that are connected altogether of the car of automobile in garage frame, every angle of car is made up of 3 hoist ropes by one group.The exit of these 4 groups of hoist ropes by above-mentioned all directive wheels and traction sheave all be placed on garage frame in counterweight link to each other.

Be shaped on grooving on the traction sheave in the utility model.

The utility model has following accompanying drawing:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the traction sheave structural representation in the utility model.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:

6 supporting

seats

6,11,3,15,19,23 are packed on the carrier bar 4 on the garage frame 1, and in order to make 6 supporting seat arrangements reasonable, it is also reasonable to reach the garage weight distribution, thus the indirect request of 6 supporting seats keep at a certain distance away, as shown in Figure 1.On supporting seat 6, install following two

directive wheels

5,8; Install following two

directive wheels

10,12 on the supporting seat 11; And a directive wheel 9 is installed on supporting seat 3; A directive wheel 14 is installed on the supporting seat 15; Also install following two

directive wheels

18,20 on the supporting seat 19; Install following two

directive wheels

22,24 on the supporting seat 23 equally.Install traction machine 25 again on carrier bar, install motor 21 on the traction machine, present embodiment is selected the ac variable frequency speed regulation motor for use.The two ends of the output shaft of installing in traction machine 26 are installed a

traction sheave

27,17 respectively after stretching out traction machine, such mounting method makes spacing increasing between two traction sheaves, reaches the width and all very big purpose of length of the car 29 that is applicable to the automobile placed in the garage frame.The 4 groups of

hoist ropes

7,13,16,28 that on four jiaos of car, are connected altogether, every angle of car has one group, and it is made up of 3 hoist ropes.The exit of one group of hoist ropes 7 wherein is connected by directive wheel 24 and traction sheave 27 and

directive wheel

22,8 and the counterweight 2 that is placed in the garage frame; The exit of one group of hoist ropes 13 wherein is connected by directive wheel 20 and traction sheave 17 and

directive wheel

18,12 and counterweight; The exit of another group hoist ropes 16 wherein is connected with counterweight by directive wheel 14 and traction sheave 17 and directive wheel 10; The exit of another group hoist ropes 28 wherein is connected with counterweight by directive wheel 9 and traction sheave 27 and directive wheel 5.Hoist ropes in the said structure during by traction sheave the traction direction be horizontal direction, and on traction sheave, all be shaped on grooving 30, hoist ropes is around in the grooving.

Operating principle of the present utility model is: two traction sheaves are installed under the ac variable frequency speed regulation motor-driven after stretching out traction machine by the two ends of output shaft in the traction machine, utilize the frictional force transferring power between the grooving on hoist ropes and the traction sheave, thereby formed traction capacity, and two traction sheaves drive by four groups of next hoist ropes of both direction, the traction angle is more than or equal to 180 degree, therefore increased work moment greatly, the also corresponding increase of traction capacity, traction ratio is 1: 1.

Advantage and the good effect that the utlity model has are: when passing through traction machine owing to hoist ropes , be horizontal force, thus traction capacity improve, traction machine be subjected to by car with counterweight Pressure is very little, and the pressure of both direction can be cancelled each other, and the traction machine operation conditions is changed Kind. Owing to spacing between two traction sheaves is big, hoist ropes is fixed on four jiaos of cars again, therefore suitable Be used for width and length all very big car also improved the robust motion of car and relaxed simultaneously Suitable sense. The utility model is simple in structure in a word, and cost is low, and safety coefficient is big, and it is little to consume energy.
