DETAILED DESCRIPTION

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0019] Example:

[0020] Reference Figure 1This embodiment provides an auxiliary joint device for use in mines. It includes a hollow pipe rack 8 positioned at the head of a cantilevered tunnel boring machine. The device is characterized in that a multifunctional bracket 1 is positioned outside the hollow pipe rack 8. A transfer plate 2 is mounted above the multifunctional bracket 1. Several pairs of first connecting lugs 3 are mounted at the tail ends of the opposing end surfaces of the multifunctional bracket 1 and the transfer plate 2. The multifunctional bracket 1 and the transfer plate 2 are hingedly connected via pins disposed on the first connecting lugs 3. Several mounting holes for mating with a drilling rig base 4 are disposed in the middle of the transfer plate 2. A second connecting lug 5 is also disposed on the transfer plate 2. A hydraulic telescopic rod 6 is hingedly mounted on the second connecting lug 5. A positioning clamp 7 is also mounted on the multifunctional bracket 1. The other end of the hydraulic telescopic rod 6 is hingedly mounted on the positioning clamp 7. In this embodiment, two pairs of first and second connecting lugs are provided on the transfer plate, symmetrically mounted on the left and right sides of the transfer plate.

[0021] The multifunctional bracket 1 includes a back plate 1A mounted on the rear flange of the hollow pipe frame 8; two oppositely placed clamping plates 1B are mounted on the front end face of the back plate 1A; a plurality of rib assemblies 1C are arranged between the two clamping plates 1B; the hollow pipe frame 1 is arranged through the rib assemblies.

[0022] Each rib assembly 1C comprises two upper and lower sub-plates, which are detachably connected by a bolt assembly. Semicircular grooves are formed on opposite end faces of the sub-plates, and the inner diameter of the semicircular grooves is consistent with the outer diameter of the hollow pipe rack 1. Reinforcing ribs are also provided between the back plate 1A and the clamping plate 1B.

[0023] There are two pairs of first connecting ear plates 3 on the multifunctional bracket 1, which are symmetrically arranged at the positions of the back plate 1A.
