Description

Technical Field

[0001] The invention relates to a tunnel engineering construction technology, in particular to a rail transport passing system for tunnel micro-step construction. Background Art

[0002] In order to convey water or discharge flood water in water conservancy projects, closed tunnel water channels are often built by excavating through mountains. When constructing micro-steps inside the tunnel, rail transport vehicles are needed to transport the required materials and equipment to the construction site inside the tunnel. Since the transport vehicles need to drive in and out at the same time when driving, a transport passing platform is set inside the tunnel. When the existing transport vehicles pass each other, the steering controller is controlled to make one transport vehicle stay on the passing mobile platform, and then the steering controller is adjusted to make the other transport vehicle pass the passing mobile platform, and finally the transport vehicle staying on the passing platform continues to move forward, so that the two transport vehicles can pass each other. However, there are still the following problems:

[0003] 1. When the transport vehicles are driving in the tunnel, two transport vehicles drive to the passing platform at the same time, and one transport vehicle needs to stay on the passing platform before the other transport vehicle can pass. The passing is more cumbersome, which reduces the working efficiency of the transport vehicles.

[0004] 2. When the transport vehicle is driving in the tunnel, if only one transport vehicle drives to the passing position, this transport vehicle also needs to drive through the passing platform. In addition, the transport vehicle is prone to vibration when passing, causing friction and collision of the transported materials, which greatly reduces the stability of the transport vehicle. Summary of the invention

[0005] The object of the present invention is to provide a rail transport passing system for tunnel micro-step construction to solve the problems existing in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a rail transport passing system for tunnel micro-step construction, comprising a tunnel, a groove is formed on the inner bottom wall of the tunnel, two support plates are fixedly connected to the inner bottom wall of the groove, a base plate is slidably connected to the adjacent sides of the two support plates, two limit plates are symmetrically welded to the upper surface of the base plate, a second plate body is welded to the upper surface of the two limit plates, two first springs are welded to the upper surface of the base plate, a first plate body is slidably connected to the adjacent sides of the two support plates, two first rod bodies are welded to the lower surface of the first plate body, a third plate body is welded to the lower surface of the two first rod bodies, a first rail is installed on the upper surface of the second plate body, a fixed plate is welded to one side of one of the support plates, and a fixed plate is fixed to the upper surface of the second plate body. A forward and reverse motor is installed on the upper surface of the fixed plate, and a gear is welded on the output end of the forward and reverse motor. A rack is arranged inside the groove, and the rack and the gear are meshed. A sixth plate body is welded on one side of the rack, and a second track is installed on the upper surface of the sixth plate body, and first movable tracks are respectively installed at both ends of the second track.

A controller is installed on the inner wall of the tunnel, and a signal output end of the infrared sensor is electrically connected to a signal input end of the controller through a wire, and an electrical output end of the controller is electrically connected to an electrical input end of the forward and reverse motor through a wire.

[0007] As a further preferred embodiment of the technical solution: a second spring is uniformly welded on the lower surface of the base plate, and the bottom of the second spring is in contact with the inner bottom wall of the groove.

[0008] As a further preferred embodiment of the present technical solution: a fourth plate body is hinged on one adjacent side of the two limit plates, and the top of the first spring is welded to the lower surface of the fourth plate body; two rubber pads are symmetrically bonded to the lower surface of the third plate body, and the lower surfaces of the two rubber pads are respectively attached to the upper surface of the fourth plate body.

[0009] As a further preferred embodiment of the technical solution: two through grooves are symmetrically provided on the upper surface of the first plate body, and the two limit plates are respectively slidably connected to the inside of the through grooves.

[0010] As a further preferred embodiment of the present technical solution: the lower surface of the sixth plate body is hinged to the fifth rod body and the fourth rod body respectively, the rear surface of the fourth rod body is hinged to the front surface of the fifth rod body, the ends of the fifth rod body and the fourth rod body away from the sixth plate body are hinged to the third rod body and the second rod body respectively, and one end of the third rod body and the second rod body are both hinged to the inner bottom wall of the tunnel.

[0011] As a further preferred embodiment of the technical solution: a fifth plate body is fixedly connected to one side of the inner bottom wall of the tunnel, and one side of the sixth plate body is slidably connected to one side of the fifth plate body.

[0012] As a further preferred embodiment of the technical solution: a slide groove is provided on one side of the fifth plate body, a slider is welded on one end of the sixth plate body, and the slider is slidably connected to the inside of the slide groove.

[0013] The beneficial effects of the present invention are:

[0014] 1.
