Description

Technical Field

[0001] The utility model relates to the technical field of tunnels constructed by mechanical methods, and particularly refers to a mechanical method interval track tensioning device. Background Technique

[0002] In the construction of mechanical method interval tunnels, electric locomotives are required as carriers for horizontal transportation to transport construction consumables and muck for external transportation. Therefore, the horizontal transportation in the tunnel directly affects production efficiency and production safety.

[0003] However, during the process of the electric locomotive transporting consumables and muck, due to the slope or turning of the tunnel, when the electric locomotive is carrying heavy transportation items, a lateral release force will occur in the slope section or turning section of the tunnel, causing the guide rail to shift towards both sides, resulting in the electric locomotive slipping or running out of the track during the next transportation process. In the current construction process, only the tunnel track can be continuously repaired, but this will consume a lot of time and energy in the long run. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the defects of the prior art and provide a mechanical method interval track tensioning device. By setting steel wires and turnbuckles on both sides of the sleeper, the situation of track deviation can be reduced, and by adjusting the turnbuckle, the deviated track can be quickly restored to normal.

[0005] The technical solution to achieve the above purpose is a mechanical method interval track tensioning device, which is arranged in the tunnel. The tensioning device includes:

[0006] Sleepers arranged in the tunnel, with a track fixedly installed on the top of the sleepers; and

[0007] A number of steel wires arranged oppositely on both sides of the sleeper, with one end of the steel wire away from the sleeper fixed to the side wall of the tunnel, and a turnbuckle is arranged inside the steel wire.

[0008] Furthermore, shield segments are installed on the bottom surface of the tunnel, and the sleepers are arranged on the shield segments.

[0009] Furthermore, the surface of the shield segment is arc-shaped, and the sleeper is arranged at the central position of the arc-shaped part of the shield segment.

[0010] Furthermore, the shape of the bottom of the sleeper is adapted to the surface shape of the shield segment.

[0011] Furthermore, segment bolts are fixedly installed on the shield segment, and the steel wire is fixedly connected to the segment bolt.

[0012] Furthermore, the number of the steel wires arranged is determined according to the requirements of on-site construction.

[0013] Furthermore, the sleeper forms an installation end corresponding to the track, and the track is fixedly installed on the installation end.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] By arranging steel wire ropes and turnbuckles on both sides of the sleeper, the situation of track deviation is reduced, and by adjusting the turnbuckle, the deviated track can be quickly restored to normal. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is an effect diagram of the use of a mechanical method interval track tensioning device.

[0017] Legend: 1. Track; 2. Sleeper; 3. Turnbuckle; 4. Steel wire rope; 5. Shield segment; 6. Segment bolt. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following further describes the present utility model in conjunction with the drawings and specific embodiments.

[0019] Refer to Figure 1 , a mechanical method interval track tensioning device is arranged in a tunnel. The tensioning device includes: a sleeper 2 and a steel wire rope 4. The sleeper 2 is arranged in the tunnel, and a track 1 is fixedly installed on the top of the sleeper 2; and a plurality of steel wire ropes 4 are oppositely arranged on both sides of the sleeper 2. One end of the steel wire rope 4 far from the sleeper 2 is fixed to the side wall of the tunnel, and a turnbuckle 3 is arranged in the steel wire rope 4.

[0020] In the present utility model, a preferred embodiment is: a sleeper 2 is arranged in the tunnel, and a track 1 is arranged on the sleeper 2. Preferably, the track 1 is fixedly installed on the sleeper 2 by welding or bolt connection, and the sleeper 2 is fixed in the tunnel by bolts or welding. Preferably, the sleeper 2 is arranged at the center position of the tunnel. A plurality of steel wire ropes 4 are arranged on both sides of the sleeper 2, and a turnbuckle 3 is arranged on the steel wire rope 4. The sleeper 2 is pulled by the steel wire rope 4 to reduce the lateral pressure generated by the motor vehicle on the track 1 in the loaded state. The turnbuckle is adjusted to tension the track. During use, construction workers can adjust the turnbuckle according to the deviation amount to make the track 1 return to the normal state, and the maintenance work is more convenient.

[0021] Furthermore, shield segments 5 are installed on the bottom surface of the tunnel, and the sleeper 2 is arranged on the shield segments 5. Preferably, a plurality of the shield segments 5 are provided, and the shield segments 5 are arranged along the extension direction of the tunnel.

[0022] Furthermore, the surface of the shield segment 5 is arc-shaped, and the sleeper 2 is arranged at the central position of the arc-shaped part of the shield segment 5.

[0023] Furthermore, the shape of the bottom of the sleeper 2 is adapted to the shape of the surface of the shield segment 5. By adapting the shape of the bottom of the sleeper 2 to the shape of the bottom of the shield segment 5, when the sleeper 2 is set, the sleeper 2 can be assembled on the shield segment 5, avoiding the generation of gaps between the sleeper 2 and the shield segment 5, so that during the driving process of the battery locomotive, due to the excessive self-weight of the battery locomotive, the track 1 and the sleeper 2 are deformed in the vertical direction and cannot be adjusted by the turnbuckle 3.

[0024] Furthermore, a segment bolt 6 is fixedly installed on the shield segment 5, and a steel wire rope 4 is fixedly connected to the segment bolt 6. Preferably, a part of the segment bolt 6 is buried in the shield segment 5 to ensure the connection strength between the segment bolt 6 and the shield segment 5.

[0025] Furthermore, the number of the steel wire ropes 4 is determined according to the requirements of the on-site construction.

[0026] Furthermore, the sleeper 2 is formed with an installation end corresponding to the track 1, and the track 1 is fixedly installed on the installation end. Preferably, the width of the installation end is adapted to the width of the track, so as to facilitate the stress of the track to be conducted to the installation end. When the track is deformed, the stress generated by the deformation can be conducted to the installation end, and then conducted to the steel wire rope through the sleeper.

[0027] Furthermore, the steel wire rope is fixed to the side of the installation end.

[0028] The following describes the use process of a mechanical method interval track tensioning device of the present utility model.

[0029] During the construction of the tunnel, the shield segment 5 is set on the bottom surface of the tunnel. Preferably, the shield segment 5 can be built by the shield machine during the process of drilling the tunnel. The sleeper 2 is arranged in the shield segment 5, and the track 1 is arranged on the sleeper 2. Preferably, the track 1 is fixedly installed on the sleeper 2 by welding or bolt connection. The sleeper 2 is fixed in the tunnel by bolts or welding. Preferably, the sleeper 2 is arranged at the center position of the tunnel. A plurality of steel wire ropes 4 are arranged on both sides of the sleeper 2. A turnbuckle 3 is arranged on the steel wire rope 4. The sleeper 2 is pulled by the steel wire rope 4 to reduce the lateral pressure generated by the battery locomotive on the track 1 in the loaded state. During use, the construction personnel can adjust the turnbuckle according to the deviation amount to make the track 1 return to the normal state, and the maintenance work is more convenient.
