Abstract

The utility model discloses a chain track type stair lift, which is composed of two grooved sheaves, a specific chain, a track and a support, wherein a rubber layer is bonded on the outer layer of the chain. The chain track type stair lift can be mounted on luggage carts, perambulators, luggage carriers and wheel chairs. When running on flat ground, the grooved sheaves contact with the ground as general luggage carts do, when running up stairs, the outer rim of the chain contacts with edges of the stairs, rollers of the chain can be rolled in the track and the grooved sheaves, and thereby carts can be stably pulled upstairs with economized labor.

Description

Track-mounted is climbed the building device

Affiliated technical field

The utility model relates to a kind of communications and transportation device, and it is installed on loading dolly, perambulator, baggage container, the wheelchair and just can tops bar reposefully, stair climbing.

Background technology

At present, the loading dolly of market sale, perambulator, baggage container, wheelchair structure are made up of vehicle frame and roller.All powerless when crossing step and going upstairs, car, chest must be lifted away from ground, on the market several cart for travelling up or down stairss are arranged now, a kind of is to divide two groups by six wheels, and every group of three wheels, this dolly use effort, vibration is big, and effect is undesirable.

Another kind of cart for travelling up or down stairs is made up of the wheel of two groups of straight-though arrangements, but this device still has certain resistance and vibration when the corner angle of process stair.Nearly about 200 patents relevant of Patent Office of the People's Republic of China's approval have been consulted, not the structure identical with this device with cart for travelling up or down stairs.

Summary of the invention

Can not climb the shortcoming in building and the shortcoming that existing various cart for travelling up or down stairs resistances are big, vibrations are big in order to overcome existing loading dolly, perambulator, baggage container, wheelchair, the utility model provides a kind of building device of climbing, this is climbed the building device and can not only move on the level land, and the stair climbing of topping bar easily.

The technical scheme that its technical matters that solves the utility model adopts is: be made up of two sheaves, special chain, guide rail and support.Object adopts roll mode more laborsaving than sliding type when mobile, so the mankind have invented wheel and bearing.But the object that wheel and bearing are housed must could move on more smooth ground, and it is just powerless to run into step or stair.Suppose that wheel is very big, it just can be in stair or rugged ground surface.Analyze the structure of a lower bearing, bearing mainly is made up of rigidity inner ring, outer ring, roller.If the outer ring is made flexible, just can make microscler bearing, wherein can make linear structure for one section, come kiss the earth just to be equivalent to the infinitely-great wheel of diameter with this section.The effect of special chain just is equivalent to the outer ring of bearing, but it be subjected to force direction the same with bearing, be radial force, rather than resemble and be subjected to pulling force the chain.The effect of guide rail and sheave is equivalent to bearing cone.Whole device is seen the bearing that resembles a flattening from profile, and its effect also is equivalent to bearing.Such twin installation is fixed on the various dollies, just is equivalent to car to be pulled on stair like a cork at stair upper berth one block plate.

Special chain is riveted together by wide Chain link for chain grate, narrow chain sheet, roller, the pin that section is n shape, and roller and pin free-running fit guarantee that roller rotates flexibly.The thick rubber layer of the bonding one deck 3mm of the outermost layer of chain, it can protect chain and stair not to be damaged, and effect is similar with rubber tire.The effect of this chain not only is equivalent to the outer ring of bearing but also is equivalent to retainer.When level walking, sheave contacts to earth, and is identical with general dolly, the seamed edge of the outer rim of chain contact stair when going upstairs, and the roller of chain rolls in guide rail and sheave, and guide rail is level and smooth rigid body, and motion at this moment resembles train and travels along the railway track.This device is installed on baggage car, carriage for children, baggage container, the wheelchair, just can steadily pull on stair effortlessly.

The beneficial effects of the utility model are, baggage container, wheelchair that a large amount of shopping carts, perambulator, belt wheel are arranged in the society, all powerless when crossing step and going upstairs, car, chest must be lifted away from ground, this covering device has been arranged, just can haul car and go upstairs, save muscle power, be particularly suitable for the elderly, women, physical weak person.There is the building that does not much have elevator China big and medium-sized cities, and demand should be very extensive.

The specific embodiment

In Fig. 1, two sheaves (4) are installed in support (3) two ends.Along two sheave tangential directions, a guide rail (2) is arranged, its effect: limit the motion along its length in guide rail of special chain, can not swing towards both sides, when chain contact stair seamed edge, the roller on the chain can roll along guide rail, transmits power by guide rail simultaneously.Guide rail links to each other with support welding or riveted joint, and the guide rail two ends reach in the sheave groove, and when climbing building device motion, the stair seamed edge contacts from contacting with guide rail to carry out the transition to reposefully with sheave.

In Fig. 2, climbing the building device can be connected with loading dolly, perambulator, baggage container, wheelchair by installation sheet or other framing member etc., and these transportation meanss have just had the building of climbing function like this, and climbing the building device needs to use in pairs.

The structure of special chain as shown in Figure 6, it is made up of wide, narrow two kinds of Chain link for chain grate (6,7) and roller (9), outer most edge is the plane, and it and bearing are compared, Chain link for chain grate is equivalent to the outer ring of bearing, roller (9) is equivalent to ball.Be protection chain and stair, chain outer rim sticker rubber plate (8).

The sheave structure as shown in Figure 3, Figure 4, chain is embedded in the groove, during the stressed rolling of sheave, chain can not move, the friction force between them is very little.

Support (3), guide rail (2) weld or are riveted together, and form parts such as Figure 10, shown in Figure 11, its effect: link to each other with other carrier, two sheaves are installed, special chain is installed, form and climb the building device.
