Embodiment 1
[0032] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 as shown, figure 2 The middle arrow shows the tunneling direction. The serial numbers in the figure are as follows: 1. Cutting head with variable diameter function, 2. Screw conveying shaft, 3. Drive motor, 4. Hollow shaft reducer, 5. Life preserver, 6. Propelling cylinder, 7. Auxiliary cylinder, 8. Sliding base, 9, sliding shoe, 10, guide rail, 11, electric winch, 12, angular contact bearing, 13, thrust bearing, 14, oil tank, 15, pumping station motor, 16, hydraulic pump, 17, valve group, 18, Power distribution cabinet, 19, control cabinet, 20, chassis, 21, bed, 22, bed skids, 23, head cover, 24, coupling, 25, squirrel cage thrust frame, 26, end of life preserver Transition joint, 27, side scraper, 28, steel wire rope, 29, hinge, 30, mandrel, 31, bearing seat, 32, screw conveyor shaft extension joint, 33, safety belt, ...
Embodiment 2
[0058] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14 shown. The lifesaving machine structure and lifesaving process of this embodiment are basically the same as those of Embodiment 1, but also have the following differences.
[0059] The driving motor in the rotary drive device of the screw conveying shaft is changed to a hydraulic motor, and the electric winch is changed to a hydraulic winch.
[0060] For the convenience of transportation, the chassis 20 is changed from integral type to split type. It is composed of 2 boxes, the split plane is located in the middle, and each of the two boxes is provided with a connection plate, which is connected with high-strength bolts. The split type chassis is convenient. Transportation under construction.
[0061] After forming a transparent space in the life-saving cylinder 5, use a commerci...
