An I-beam 8 track is laid in the tunnel. When in use, the traveling trolley 1 is driven by the traveling mechanism to move along the I-beam 8 track, and the traveling device drives the auxiliary trolley 4 to move along the I-beam 8 track, and the traveling trolley 1 is synchronized with the auxiliary trolley 4. The traveling device of the auxiliary trolley 4 may be equipped with a separate driving unit, so that the driving unit drives the auxiliary trolley 4 to move alone, or the traveling device of the auxiliary trolley 4 is in a driven form, the traveling trolley 1 moves and drives the auxiliary trolley 4 to move through the connecting rod 3, thereby ensuring the synchronization of the traveling trolley 1 and the auxiliary trolley 4. Here, the specific form of the traveling device of the auxiliary trolley 4 is not limited; preferably, the traveling device of the auxiliary trolley 4 is in a driven form, the traveling mechanism drives the traveling trolley 1 to move, and drives the wheels on the auxiliary trolley 4 to move along the I-beam 8 track through the connecting rod 3, thereby realizing the movement of the auxiliary trolley 4, and making the auxiliary trolley 4 synchronized with the traveling trolley 1. During the construction operation, the storage battery 5 supplies power to the traveling mechanism and the electric hoist 2, etc., avoiding the laying of a long busbar and related equipment, reducing the trouble of construction operation and improving work efficiency.

[0027] like Figure 1-Figure 4As shown, the travel mechanism includes two symmetrical and spaced mounting members 6, which are fixedly connected by a connecting member, and also includes a driving mechanism, which is a reduction motor 9, which is fixedly connected to the outer wall of one of the mounting members 6, and the output shaft of the reduction motor 9 passes through the mounting member 6 and is rotatably connected to the mounting member 6, and the end of the output shaft of the reduction motor 9 is drivingly connected to a driving travel wheel 10, so that the driving travel wheel 10 can be driven by the reduction motor 9, and the driving travel wheel 10 is located below the I-beam 8, and a travel track 11 adapted to the driving travel wheel 10 is fixedly connected to the bottom of the I-beam 8, and the driving travel wheel 10 travels along the travel track 11. The two mounting members 6 are rotatably connected with driven wheels 7, which are set against the top of the lower wing plate of the I-beam 8 track, and the driven wheels 7 move along the lower wing plate of the I-beam 8 track. Here, the running track 11 can be selected from conventional tracks with smooth surfaces, and accordingly, the active running wheel 10 can also be a conventional wheel. The running track 11 can also be selected from a rack, and accordingly, the active running wheel 10 can be selected from a gear; the running track 11 can also be selected from a chain, and accordingly, the active running wheel 10 can be selected from a sprocket. Here, there is no specific restriction on the structure of the running track 11 and the active running wheel 10. When in use, the reduction motor 9 is started, and the output shaft of the reduction motor 9 drives the active running wheel 10 to rotate, so that the active running wheel 10 moves along the running track 11, and the driven wheel 7 moves along the lower wing plate of the track of the I-beam 8.

[0028] In another embodiment, Figure 4 As shown, there are two running tracks 11, and both running tracks 11 are arranged along the length direction of the I-beam 8; a driven running wheel 12 adapted to the running track 11 is rotatably connected to the mounting member 6 away from the reduction motor 9. The arrangement of the two running tracks 11 improves the stability of the trolley 1 in the left and right directions to a certain extent, reduces the deflection of the trolley 1, and improves the running stability of the trolley 1. Specifically, the reduction motor 9 drives the active running wheel 10 to move along the running track 11, and at the same time, driven by the connecting member, the driven running wheel 12 also moves along the running track 11.

[0029] In another embodiment, the travel track 11 is a chain, and the active travel wheel 10 and the driven travel wheel 12 are both sprockets.

During the driving process, the active walking wheel 10 and the driven walking wheel 12 both move along the walking track 11, so that the walking trolley 1 moves along the I-beam 8, and then the guide wheel 13 rotates. Since the guide wheel 13 abuts against the track of the I-beam 8, the guide wheel 13 plays a role in guiding and limiting the movement of the walking trolley 1, so as to further improve the stability of the movement of the walking trolley 1.

[0031] In another embodiment, Figure 1 As shown, the auxiliary trolley 4 includes two spaced and symmetrically arranged connecting plates 14, and the inner side walls of the two connecting plates 14 are provided with guide grooves corresponding to the positions of the I-beams 8, and the guide grooves are rotatably connected with limit wheels 16 adapted to the I-beams 8, and the outer edges of the limit wheels 16 are also arranged to abut against the outer edge surface of the lower wing plate of the I-beams 8.

During the movement, the limit wheels 16 rotate along the outer edge of the I-beam 8 to guide and limit the auxiliary trolley 4, thereby improving the stability of the movement of the auxiliary trolley 4. In this embodiment, the traveling device is two limit wheels 16, that is, the traveling device realizes the movement of the auxiliary trolley 4 by driving the traveling trolley 1 and the connecting rod 3 without external drive.

[0032] In another embodiment, Figure 1 and Figure 3 As shown, the connecting member includes two fixed plates 17 arranged at intervals, and the two fixed plates 17 are respectively fixedly connected to the bottom of the corresponding mounting member 6.

Therefore, the chain electric hoist 2 is selected in this embodiment to improve the service life of the crane to a certain extent.

That is, the two connecting rods 3 are respectively located on both sides of the I-beam 8, and the two ends of the connecting rod 3 are respectively connected to the mounting member 6 and the connecting plate 14 to achieve the connection between the walking trolley 1 and the auxiliary trolley 4. Specifically, the connecting rod 3 can be connected to the mounting member 6 and the connecting plate 14 by bolts, so as to facilitate its disassembly.

[0035] In another embodiment, the connecting plate 14 is also rotatably connected to a secondary running wheel (not shown in the figure) adapted to the running track 11, and the secondary running wheel moves along the running track 11. By arranging the secondary running wheel on the secondary trolley 4, if the running track 11 is a chain, the secondary running wheel is a sprocket, so as to improve the stability of the secondary trolley 4 during travel. At the same time, the inner side walls of the two connecting plates 14 are also rotatably connected to secondary wheels (not shown in the figure), and the secondary wheels move along the track of the I-beam 8.

[0036] In another embodiment, Figure 5 As shown, the driven wheel 7 is connected to the reduction motor 9 through a transmission mechanism. Correspondingly, the transmission mechanism includes a driving gear 15 located on the output shaft of the reduction motor 9. The driving gear 15 is fixedly connected to the output shaft of the reduction motor 9. A driven gear 19 meshing with the driving gear 15 is fixedly connected to the driven wheel 7 close to the reduction motor 9. The driving gear 15 is driven to rotate by the rotation of the reduction motor 9, thereby driving the driven gear 19 to rotate, thereby realizing the rotation of the driven wheel 7, thereby improving the stability and safety of the walking trolley 1 during movement.
