Detailed description of the invention
Jib crane in shield machine inverted arch block transportation system, as Fig. 1, shown in Fig. 2 and Fig. 3, comprise bracing frame 1, bracing frame 1 side top arranges hinged seat 2, the side bottom of bracing frame 1 arranges lower hinge seat 3, upper hinged seat 2 connects overturning seat 6, the upper end of overturning seat 6 and upper hinged seat 2 hinges, electric pushrod 11 is installed in the lower end of overturning seat 6, the shell hinge of electric pushrod 11 is arranged on overturning seat 6, , the hinged lower hinge seat 3 in end of the bar of electric pushrod 11, electric pushrod 11 adopts articulated manner to fix, not only keep the flexibility of running, the discrepancy that can also avoid contact to coordinate, further improve security performance.The spiral arm 7 of level is installed on overturning seat 6, and on spiral arm 7, lifting is with the slide trucks 15 of power, and the pulley 14 of slide trucks 15 coordinates with spiral arm 7, slide trucks 15 bottom fixed installation electric blocks 16.The present invention is inserted in tunnel, and slide trucks 15, along spiral arm 7 rectilinear motions, lifts inverted arch block on electric block 16.In the acclive tunnel of tool, by the distance between flexible adjustment overturning seat 6 bottoms and the bracing frame 1 of electric pushrod 11, overturning seat 6 is along the pin joint upset of upper hinged seat 2, thereby drive the vertical upset of spiral arm 7, keep spiral arm 7 state in level all the time, avoid slide trucks 15 to slide arbitrarily under Action of Gravity Field along spiral arm 7, thereby effectively improve the safety of use procedure.
In order to realize the function of spiral arm 7 Plane Rotations, rotating seat 5 and backspin transposase 11 3 are set between described overturning seat 6 and spiral arm 7, between upper rotating seat 5 and backspin transposase 11 3, vertical swingle 17 is set, upper rotating seat 5 and backspin transposase 11 3 are the fixing swingle 17 in amount end, the strong point of swingle 17 is uniform and stable, improves stability and the safety of the course of work.On swingle 17, fixedly mount spiral arm 7, the upper end of swingle 17 gearbox 18 that is connected, gearbox 18 connects motor 19, gearbox 18 and motor 19 be as power source, the preferred stepper motor of motor 19, and rotational angle controllability is high, velocity of rotation is even, and accuracy is high.Gearbox 18 and motor 19 are arranged on overturning seat 6.Spiral arm 7 is in the time adjusting transporting position, and by the effect of motor 19 and gearbox 18, driven rotary bar 17 rotates, thereby realizes the rotation of spiral arm 7, thereby slightly swings and make inverted arch block transporting position more accurate in tunnel.
In constructing tunnel, adopt line traffic control the most accurately and safety, the connection wire of slide trucks 15 is because its position is indefinite, there will be sagging, the wire of sagging position easily damages or hinders construction, unresolved this problem, the side of described spiral arm 7 arranges the straight-bar 8 of level, several slip cards 10 are set on straight-bar 8, and the card 10 that slides is made up of a ring and clamp, and ring set is contained on straight-bar 8, clamp coordinates with each section of wire 9, sliding to block on 10 arranges wire 9, and wire 9 one end connect the actuating unit of slide trucks 15, and the other end of wire 9 connects peripheral control unit.When slide trucks 15 is along in spiral arm 7 moving process, the card 10 that slides moves along straight-bar 8, thereby drives wire 9 unfold or close up, and avoids wire 9 sagging, thereby improves the safety of use procedure.
Bear a heavy burden when excessive in hinged place; can cause loosening; even come off; cause serious production accident; for to this situation emergency protection, safety vent 12 is offered at the middle part of described overturning seat 6, and safety vent 12 is towards bracing frame 1; safe connecting rod 4 is installed on bracing frame 1, and safe connecting rod 4 is inserted in safety vent 12.In the time of upper hinged seat 2 and the loosening accident of lower hinge seat 3 generation, safety vent 12 and safe connecting rod 4 coordinate, and avoid spiral arm 7 directly to topple over, and reduce the damage that accident causes, and ensure the safety of job site in time.
Technical scheme of the present invention is not restricted in the scope of embodiment of the present invention.The present invention not technology contents of detailed description is known technology.
