At present, my country has become the world's largest manufacturing base and application market for tunnel boring machines. With the rapid growth of domestic urban road transportation, railways, highways, water conservancy, municipal engineering and other construction projects, my country's tunnel boring machinery has also ushered in rapid development. Among them, tunnel boring machines are a kind of comprehensive equipment that uses machinery to crush rocks, remove mucking and support for continuous operations. According to the cutting process of the tunnel boring machine on the working surface, it is divided into full-section tunnel boring machines and partial-section tunnel boring machines. At present, during the working process, the tunnel boring machine needs to repeatedly advance and retreat the machine for more than 3 to 5 times to brush the side and sweep the top to complete the tunnel forming task. In order to prevent the running wheel from crushing the cable, the tunnel boring machine cable must be manually guarded, which brings great work fatigue and safety hazards to the employees and is inconvenient to use.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1-2. The utility model provides a technical solution: a telescopic device for a tunnel boring machine, comprising a pair of bases 1, a first column 2 and a second column 3 are fixedly provided above the pair of bases 1, an active sliding column 4 is slidably installed in the first column 2, a driven sliding column 5 is slidably installed in the second column 3, a top plate 6 is installed on the top of the active sliding column 4 and the driven sliding column 5, a support 7 is provided on the lower wall of the top plate 6, a sliding rod 8 is obliquely installed between the pair of supports 7, a plurality of sliding sleeves 9 are slidably sleeved on the sliding rod 8, a lifting assembly for clamping a cable is installed at the lower end of the sliding sleeve 9, and a driving assembly is provided in the first column 2.

By adopting the above technical solution, when installing the cable, the cable can be fixed by the lifting assembly, and then the driving assembly can be used to drive the active sliding column to slide upward, and cooperate with the driven sliding column to make a pair of top plates drive the sliding rod to rise. At this time, under the action of the sliding sleeve, the cable can automatically extend and retract following the advance and retreat of the tunnel boring machine, and the sliding rod is set at an angle, so that the sliding sleeve can move along the sliding rod one by one.

This embodiment is further configured such that the driving assembly includes a screw rod 10 rotatably installed in the first column 2, a screw hole matching the screw rod 10 is opened in the active sliding column 4, a motor 11 is provided on the outer wall of the first column 2, a driving end of the motor 11 extends into the first column 2 and is fixedly installed with a main gear 12, and a sub-gear 13 meshing with the main gear 12 is mounted on the screw rod 10.

By adopting the above technical solution, when the height of the slide bar needs to be adjusted, the motor can be started to drive the main gear to rotate, and the secondary gear engaged with it drives the screw to rotate, so that the active slide column drives the top plate to move upward, and the driven slide column on the other side moves upward synchronously, completing the height adjustment of the slide bar, making it convenient for the subsequent cable to move with the tunnel boring machine.

The present embodiment is further configured such that the hanging assembly comprises a hanging hook 14 fixedly arranged on the lower wall of the sliding sleeve 9, and a positioning bolt 15 for tightening the cable is screwed to the lower wall of the hanging hook 14.

By adopting the above technical solution, the cable is embedded in the hook, and the positioning bolt is rotated to make it press against the side wall of the cable. The cable can be clamped and fixed in cooperation with the inner wall of the hook, thereby ensuring that the cable moves synchronously with the hook.

This embodiment is further configured such that convex strips 16 are provided on both sides of the slide rod 8 , and a groove 17 matching the convex strips 16 is provided on the inner wall of the slide sleeve 9 .

This embodiment is further configured such that the inner walls of the first column 2 and the second column 3 are both provided with guide grooves 18 , and the side walls of the active sliding column 4 and the driven sliding column 5 are both provided with guide blocks 19 slidably connected to the guide grooves 18 .

The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process.

Embodiment: When in use, the cable is embedded in the hook 14, and the positioning bolt 15 is rotated to make it close to the side wall of the cable. The inner wall of the hook 14 can be used to clamp and fix the cable, thereby ensuring that the cable moves synchronously with the hook 14. The motor 11 is started to drive the main gear 12 to rotate, and the sub-gear 13 engaged with it drives the screw 10 to rotate, thereby making the active sliding column 4 drive the top plate 6 to move upward, and the driven sliding column 5 on the other side moves upward synchronously to complete the height adjustment of the slide bar 8. At this time, under the action of the sliding sleeve 9, the cable can automatically extend and retract following the advance and retreat of the tunnel boring machine, and the slide bar 8 is tilted, so that the sliding sleeve 9 can move along the slide bar 8 one by one.
