Please refer to FIGS. 1 to 13. FIG. 1 is a schematic structural diagram of an embodiment of an arc track wall saw according to the present invention. As shown in FIG. 1, the arc track wall saw according to the present invention includes an arc track assembly 10 and a wall saw machine. The head 20 and the wall saw head 20 are slidably connected to the arc track assembly 10, and the wall saw head 20 can be moved along the arc track assembly 10 to cut the tunnel wall. In specific operation, the arc-shaped track assembly 10 can be fixed on the track wall, or the arc-shaped track assembly 10 can be installed on the mobile trolley 30, as shown in FIG. 1, the arc-shaped track assembly 10 can be installed on the mobile stage. It can be moved quickly and conveniently on the cart 30, which improves the cutting efficiency. After the arc-shaped track assembly 10 is installed on the mobile trolley 30, the distance between the arc-shaped track assembly 10 and the tunnel wall is about 30-40mm, which facilitates the movement of the arc-shaped track assembly 10 in the tunnel and prevents arcs inside the tunnel from causing uneven arcs. When the track assembly 10 cannot pass.

FIG. 2 is a partial structural schematic diagram of an arc-shaped track assembly. As shown in FIG. 2, the arc-shaped track assembly 10 includes a track bed 11, a keel track 12, and a locking member 13. The keel track 12 is installed on the track bed 11. Then, it can be locked by the locking member 13. Figure 3 is a cross-sectional view of the AA section in Figure 2. As shown in Figure 3, the track bed 11 generally uses I-beams, and it is relatively easy to bend the I-beams into arcs corresponding to the tunnel wall surface. Die or bending machine and other processing methods to bend the I-shaped steel into an arc, but, as described in the background, it is more difficult to process the track in the prior art into an arc, the greater the stability of the hole in the track The better, the more difficult it is to bend. In the prior art, the track is made thin and flat to make the track easy to bend, but this will cause the strength of the track to decrease and the stability of the wall saw to work.

FIG. 4 is a schematic diagram of a partial structure of a keel-shaped track. As shown in FIG. 4, a plurality of grooves 121 are processed on the track to form the keel-shaped track 12 of the present invention. The groove 121 is provided on the track and fits on the track bed 11. On one side, after the keel-shaped rail 12 is attached to the arc-shaped track bed 11 and locked by the locking member 13, the radian of the keel-shaped track 12 and the track bed 11 can be fitted, and the keel of the groove 121 is processed.

The grooves 121 are generally provided on the keel-shaped track 12 at equal intervals, and one groove is provided every predetermined distance.

The keel-shaped track 12 can be integrally formed or spliced from several track units. That is to say, the keel track 12 can be directly processed into the same length as the track bed 11, or the keel track 12 can be divided into several units and spliced to the track bed 11 in small sections. It can be understood that the track bed 11 may also be formed in an integrated manner and a segmented manner.

The radian of the track bed 11 is determined by the radian calculation of the tunnel wall. The keel track 12 has a wide range of bends and can be reused. It can be used with the track bed 11 with different radians, and it can also be used with straight tracks in straight track cutting. The bed is used in cooperation, so the keel rail 12 of the present invention becomes a universal rail.

The track bed 11 is formed by segmented splicing, which can be repeatedly installed on the mobile trolley 30 and can be easily removed from the mobile trolley 30. After the track bed 11 is mounted on the mobile trolley 30, the keel rail 12 is installed. On the track bed 11, an arc-shaped moving trolley is formed.
