Abstract
The utility model relates to a kind of mechanical paw, is used for various shield machines.This utility model, including hydraulic cylinder 1, paw 5 and frame 3.Described hydraulic cylinder 1 is connected with frame 3 by hydraulic cylinder base 2, and described paw 5 top is connected with hydraulic cylinder rod 6 by articulation hole bolt 4, is connected with frame 3 by pin 7 in the middle part of paw 5.The utility model can not only solve the safety problem of staff, and simple to operation, it is possible to increase the operating efficiency of shield machine.
Description
Technical field
The utility model relates to a kind of mechanical paw, particularly relates to one and can be arranged on shield machine inner utilization hydraulic means
Chute lever clamping device is driven to exchange the mechanical paw of hobboing cutter for.
Background technology
With increasing of vehicle, urban transportation is more and more crowded, the increase in demand of city underground, it would be desirable to utilize shield
The underground space developed by machine.Shield machine operationally, anterior cutterhead serious wear, need tool changing at any time.But the work of being currently
Enter as personnel and inside shield machine, carry out tool changing, underground activities bad environments.And in order to soil layer does not caves in, need to increase
Pressure.In case of high pressures, health is highly susceptible to injury.
Content of the invention
Technical problem to be solved in the utility model is: provide one be arranged on inside shield machine, and simple to operate, subtract
Few injury to people, can quickly grip the mechanical paw of hobboing cutter on shield machine.
The technical solution adopted in the utility model is: a kind of mechanical paw changing hobboing cutter for shield machine, including hydraulic cylinder,
Paw and frame.Described hydraulic cylinder is connected with frame by hydraulic cylinder base, and described paw top is by articulation hole spiral shell
Bolt is connected with hydraulic cylinder rod, and middle part is connected with frame by pin.
A kind of mechanical paw changing hobboing cutter for shield machine, is further characterized in that: frame can be dismantled with paw section, and
Symmetrical.
A kind of mechanical paw changing hobboing cutter for shield machine, is further characterized in that: paw front end uses two to grip semicircle.
A kind of mechanical paw changing hobboing cutter for shield machine, is further characterized in that: hydraulic cylinder rod and frame, and paw composition is sliding
Groove lever clamping device.
The utility model provides the benefit that: the utility model, owing to using above structure, can not only solve staff's
Safety problem, saves tool change time, cost-effective, and simple to operation, it is possible to increase the operating efficiency of shield machine.
Brief description
Fig. 1 is the schematic diagram of the mechanical paw that shield machine changes hobboing cutter
Fig. 2 is the hydraulic cylinder rod end enlarged drawing of the mechanical paw that shield machine changes hobboing cutter
In figure, 1 hydraulic cylinder, 2 hydraulic cylinder bases, 3 frames, 4 articulation hole bolts, 5 paws, 6 hydraulic cylinder rods, 7 pins.
Detailed description of the invention
Below by specific embodiment, the utility model is described in further detail.
Shown in embodiment 1: Fig. 1.A kind of mechanical paw changing hobboing cutter for shield machine, including hydraulic cylinder 1, paw 5 and
Frame 3.Described hydraulic cylinder 1 is connected with frame 3 by hydraulic cylinder base 2, and articulation hole bolt 4 is passed through on described paw 5 top
It is connected with hydraulic cylinder rod 6, be connected with frame 3 by pin 7 in the middle part of paw 5.
Shown in embodiment 2: Fig. 1.Frame 3 can be dismantled becomes one piece of large platform and 4 pieces of little supports, and 4 pieces of supports are two
Right and symmetrical.
Shown in embodiment 3: Fig. 1.Paw 5 can be dismantled becomes two follower levers, two U-shaped forks and two double nahlocks.
Shown in embodiment 4: Fig. 1.When paw 5 will close to cutter when, hydraulic cylinder rod 6 is extrapolated, drive paw 5 front end open
Opening, manipulator continues to advance, and when reaching precalculated position, hydraulic cylinder rod 6 is inwardly received, and drives paw 5 front end to close up, thus catches
Cutterhead, manipulator is pulled back, and takes out cutter.
