Embodiment 1

[0017] Such as figure 1 , figure 2 Among them, a self-propelled turnout includes a turnout 4, and the turnout 4 is fixedly installed on a steel platform 3. A plurality of supporting steel beams 2 are arranged on the lower part of the steel platform 3, and a telescopic device 5 is arranged on the supporting steel beam 2. The telescopic device 5 and the Walking wheel 1 is connected.

[0018] The telescopic device 5 is a hydraulic cylinder. In this example, the piston rod of the hydraulic cylinder is connected to the shaft of the road wheel 1 . The shaft of the walking wheel 1 is slidably installed in the supporting steel beam 2,

[0019] The traveling wheel 1 is connected with a motor (not shown in the figure).

[0020] When in use, the hydraulic cylinder stretches out to make the traveling wheel 1 touch the ground, and the motor is powered to drive the traveling wheel 1 to rotate, so that the steel platform 3 and the switch 4 move longitudinally as a whole; when the design...

Embodiment 2

[0022] Such as figure 1 , image 3 Among them, a self-propelled turnout, including a turnout 4, the turnout 4 is fixedly installed on a steel platform 3, a plurality of supporting steel beams 2 are arranged on the lower part of the steel platform 3, and a telescopic device 5 is arranged on the steel beam 2, and the telescopic device 5 is connected with the traveling Wheel 1 is connected.

[0023] In the telescopic device 5 , one end of the rocking arm 51 is hinged with the supporting steel beam 2 , the traveling wheel 1 is installed at the other end of the rocking arm 51 , one end of the hydraulic cylinder 52 is connected with the steel platform 3 , and the other end is connected with the rocking arm 51 .

[0024] A motor 53 is installed on the rocking arm 51, and the motor 53 is connected with the traveling wheel 1 through a reduction mechanism.

[0025] When in use, the hydraulic cylinder stretches out to make the rocker arm 51 rotate along the hinge point with the support...

Abstract

The invention provides a self-propelled turnout which comprises a turnout, wherein the turnout is fixedly arranged on a steel platform, the lower part of the steel platform is provided with multiple support steel beams, each steel beam is provided with a retractor device, and each retractor device is connected with a road wheel. The self-propelled turnout provided by the invention solves the problem that the turnout longitudinal shift is rapid and convenient in the existing tunnel construction process, the straight line construction period of tunnel construction can not be occupied, and the operating efficiency is improved. The self-propelled turnout provided by the invention has the advantages of design principle clearness, simple structure, easiness in manufacture, convenience in operation, low cost and the like.

Description

technical field [0001] The invention relates to a turnout used for guide rails in the field of tunnel construction, in particular to a movable self-propelled turnout. Background technique [0002] With the continuous development of tunnel construction in my country, currently in the process of tunnel traffic, turnouts need to be disassembled frequently, which is labor-intensive and inefficient, occupying the straight-line construction period of tunnel construction, unable to achieve continuous operation, and unable to meet the requirements of modern tunnel construction. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a self-propelled turnout, which can move the turnout quickly, so as to keep the traffic in the tunnel smooth. [0004] In order to solve the above technical problems, the technical solution adopted in the present invention is: a self-propelled turnout, including a turnout, the turnout is fixedly inst...
