[0024] The utility model will be further described in detail in combination with the drawings.

[0025] As Figures 1-6As shown, a cable track for a tunneling anchor machine comprises a track and a fixing base, the track body 2 of the track is made of 15mm thick steel plate and is U-shaped, the height and width can be adjusted during processing according to the used track, the bottom of the track body 2 is provided with fixing holes for fixing the track body 2 to the π-shaped beam 4 by bolts.

[0026] A φ16mm transition round steel 1 is welded on the track body 2 and the two ends of the transition round steel 1 are bent outward by 30-45° to ensure smooth passing of the track.

[0027] The fixing base is made by welding the π-shaped beam 4 and the fixing base steel plate 3, the π-shaped beam 4 is L-shaped and comprises a horizontal plate and a vertical plate, the fixing base steel plate 3 is made of 15mm thick steel plate, the π-shaped beam 4 is welded in the middle of the fixing base steel plate 3 and symmetrically drilled on the upper side for fixing to the tail beam.

[0028] The track is arranged in parallel with the tail beam, the fixing base is located below the track and serves as a connecting piece of the track and the tail beam, the fixing base steel plate 3 in the fixing base is close to the tail groove steel, the π-shaped beam 4 is L-shaped, one end of the π-shaped beam 4 is welded in the middle of the fixing base steel plate 3 and the other end of the π-shaped beam 4 is located below the track body 2 to support the track body 2.

[0029] The reserved hole of the steel plate is connected to the connecting seat of the tail beam of the belt conveyor by bolts.

[0030] The length of the track body 2 can be adjusted during processing according to the length of the single tail, generally, the length of each tail is 3m, for the convenience of installation and transportation, the cable track can be processed to be 1.5m per section to ensure that the up and down of the connection of the tail does not affect the normal use of the device.

[0031] The transition round steel 1 is arranged on the U-shaped structure of the track body 2 in the longitudinal direction of the U-shaped structure, the two ends of the transition round steel 1 are bent outward in the longitudinal direction to form a transition elbow, which can make the track automatically slide into the track body 2 during the movement of the track through the joint of the track body 2, ensuring smooth operation and reducing jamming.

[0032] The installation position and length of the device can be adjusted according to actual needs (such as the range of the cable) to adapt to different working conditions. Generally, the effective forward and backward stroke of the tunneling anchor machine is 20m, and the track can be installed outward from the last tail of the tail by 25m.

[0033] Device installation steps:

[0034] The fixing base is fixed to the side of the longitudinal beam of the belt conveyor by bolts, the fixing bolt is passed through the fixing hole and the bolt is tightened.

[0035] Put the track groove body 2 on the π-shaped beam 4, adjust the position of the track groove body 2, make the reserved hole position under the track groove body 2 align with the hole position of the π-shaped beam 4.

[0036] Pass the fixing bolt through the fixing hole of the track groove body 2 and the π-shaped beam 4, and tighten the bolt to fix.

[0037] Device disassembly steps:

[0038] Remove all bolts connecting the bottom of the track groove body 2 and the π-shaped beam 4, and take the track groove body 2 off the π-shaped beam 4.

[0039] Remove the connecting bolt of the π-shaped beam 4 and the connecting seat of the tail longitudinal beam of the rubber belt conveyor, and take off the π-shaped beam 4.

[0040] The working principle of the utility model:

[0041] One end of the fixing seat is fixed with the tail groove steel, and the upper end of the other end supports the cable groove, the track is located in the track groove body 2, and the track is internally laid with pipelines and cables.

[0042] During the forward and backward operation of the anchor excavator, the dragging track is bent and moved in the track groove body 2. When the anchor excavator retreats to the front end of the last frame of the tail (the limit distance), the track is arranged in two layers of stacking at this time, and as the anchor excavator moves forward, the upper track is dragged forward by the anchor excavator, and at this time, the track is arranged in three layers of stacking; when the anchor excavator moves to the front end (the limit distance), the upper track and the middle track are completely straightened, and at this time, the cable groove is restored to one layer of track state, so the cycle is realized, and the cable follows the forward and backward movement of the anchor excavator.
