Description
Technical field
This utility model is related to a kind of device for facilitating vehicle to turn around, and more particularly to a kind of tunnel vehicle turns around device.
Background technology
During the construction in tunnel, the transport of construction material and dregs usually needs to use truck, in order to
Freight volume is improved, truck is often sufficiently bulky, and often narrow space in tunnel, truck is thought in narrow and small tunnel
Turn around very difficult.Tunnel is generally divided into single-track tunnel and double track tunnel.In single-track tunnel, the width in tunnel is less than load-carrying
The radius of turn of automobile, truck cannot normals direction of rotation in tunnel；When single-track tunnel is shorter, truck can be direct
Reversing enters tunnel, loads dregs or is directly outputed from single-track tunnel after unloading construction material again；But when single-track tunnel compared with
Just inconvenient when long, the reversing of relatively long distance causes efficiency very low, has a strong impact on the safety of other vehicles and personnel, this
In the case of kind, often interval setting turns around hole in the single-track tunnel, but the setting in hole of turning around increased extra work amount.
In double track tunnel, truck turns around in situ to be also required to continuously to do several actions and can just complete to turn around, and turns around very time-consuming,
And safety can not be ensured.
Chinese patent CN104477147A discloses the device that a kind of arrow path vehicle turns around, and is formed by the ground in tunnel
The hole of cylinder, arranges round turntable on hole, and round turntable is supported by the supporting leg being arranged in hole, the bottom of supporting leg
Deflecting roller is provided with, vehicle is driven on rotating disk, steered wheel rotation drives rotating disk to rotate so as to realize turning around for vehicle.However, by
It is in the volume of truck is big, weight weight, very big to the pressure of rotating disk and supporting leg, so, to rotating disk and supporting leg
Weight capacity requirement is very high, and under big pressure, the movement of deflecting roller becomes very difficult to supporting leg, it is therefore desirable to which very big is outer
Power could rotate deflecting roller, and supporting leg and deflecting roller are easy to damage in this case.In addition, this device that turns around is arranged on
On the hole of tunnel ground, when tunnel is longer, need to be positioned apart from multiple such devices that turn around, increased construction cost and
Time.
