Embodiment
A kind of anti-jamming mechanism of development machine shield of the utility model is made into one with reference to the accompanying drawings and detailed description
Walk explanation：
Embodiment one：As shown in figure 1, in the present embodiment, a kind of anti-jamming mechanism of development machine shield, the development machine shield
Anti-jamming mechanism is placed between shield 6 and main driving 7, and the anti-jamming mechanism of development machine shield includes studs 1, nut
2nd, sliding block 3 and base 4, it is α to each end bottom angled that the both upper ends thereof of base 4, which is symmetrically arranged with the bottom surface angle of base 4,
Inclined-plane, a sliding block 3 is respectively placed on the inclined-plane at the two ends of base 4, the bottom of the sliding block 3 is one and slider top clip surface
Angle is α inclined-plane, the bottom bevel of sliding block 3 and the contact of incline plane at the two ends of base 4 and can slided on the inclined-plane of base 4, described
Sliding block 3 is provided with perforate, and the studs 1 passes through two sliding blocks 3 for being placed on the two ends of base 4, the two of the studs 1
Hold and distinguish attaching nut 2 in the outside of sliding block 3.
As shown in figure 4, the anti-jamming mechanism of development machine shield is placed between top shield and main driving 7.
As shown in figure 5, when running into the special operation conditions such as country rock convergence, rock crusher, shield 6 can be by country rock power F tightly
Push down, now supporting the oil cylinder 5 of shield 6 can cause oil cylinder to withdraw gradually, shield 6 due to deficiency or the oil cylinder leakage of support force
It can be forced, toward recovery, now to place the anti-jamming mechanism of shield between shield 6 and main driving 7, can by the nut 2 for tightening two ends
So that inclined-plane upward sliding of the sliding block 3 along base 4, the gradually meeting of sliding block 3 be contacted and held out against with shield 6, this shield anti-sticking crashes
Structure can provide certain support force, in certain field of load, and the anti-jamming mechanism of this shield can effectively prevent shield 6 past
Reclaim, the relation between its support force Fn that can be provided and the pretightning force Fv of nut 2 is Fn=Fv/tan α.
As shown in fig. 6, when needing by this special formation, come loose nut 2, due to the pressure of shield 6, sliding block 3 can edge
The inclined-plane of base 4 now withdraws oil cylinder 5, shield 6 is and then toward recovery to downslide.Because rock has certain self-stability in itself, now
The shield 6 being stuck can free, in the presence of propulsive force, and development machine can continue to tunnel forward.
