Problems solved by technology

[0004] Since the general traction part of the tunnel track-laying vehicle is moved by the track head or manpower, it takes manpower and material resources
And the length of the track laying is not only limited by the rail cars but also limited by the curvature radius of the tunnel
Moreover, the overall situation cannot be observed during the track laying process, and the positioning deviation is large
Time-consuming

Embodiment Construction

[0028] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0029] Such as figure 1 , 2 As shown, a sharp-turn tunnel track-laying car includes at least two car bodies 1, a driving device 2, and a rail-grabbing mechanism 3. Two adjacent car bodies 1 are connected by a flexible rotating pendulum 4, and each car body The body 1 is correspondingly provided with a driving device 2 for driving the vehicle body 1 to move, and the rail gripping mechanism 3 is provided on the vehicle body 1 for picking and placing the rail 6 . Two adjacent car bodies 1 of the product of the present invention are connected by a flexible rotating pendulum 4, which can realize arbitrary rotation between car bodies 1 and car bodies 1, and facilitate the laying of the track 6 when turning with a small r...

Abstract

The invention relates to a sharp-curve tunnel track-laying vehicle, comprising at least two vehicle body segments, driving devices and a track gripping mechanism; the adjacent vehicle body segments are connected through a flexible rotating pendulum, each vehicle body segment is provided with one driving device, the driving devices are used for driving the vehicle body segments to move, and the track gripping mechanism is arranged on the vehicle body segments and used for picking and laying a track. The sharp-curve tunnel track-laying vehicle has the advantages that vehicle body segments can optionally rotate relative to one another, laying of a small-radius curve track is facilitated, and a power system has lower consumption of manpower and material resources.

Description

technical field [0001] The invention relates to the technical field of a tunnel track-laying vehicle, in particular to a sharp-turning tunnel track-laying vehicle. Background technique [0002] In tunnel construction, the excavated chamber has straight and curved sections. In the straight section, the ordinary track laying scheme can be used. However, if a tunnel with a sharp turn is encountered, the linear track laying vehicle cannot be used due to the limitation of the turning space. To adjust the direction arbitrarily, it is necessary to have a track-laying vehicle whose head and tail can be combined in any direction. Two mirrors are installed in the middle of the vehicle, and one side is closed to see the front and rear running conditions. [0003] Because the general tunnel track-laying vehicle can only walk forward in a straight line, it is very heavy in front of the small-radius tunnel, and it will get stuck due to the space limitation at the rear, and the front tract...
