The following embodiments are provided to describe the embodiments of the present invention, and to further describe the detailed description of the embodiments of the present invention, such as the shapes, configurations, mutual positions and connection relationships of the components, the functions and operation principles of the components, the manufacturing processes and operation methods, etc., so as to help those skilled in the art to more fully, accurately and deeply understand the inventive concept and technical solutions of the present invention.
As shown in fig. 1, a linkage device for cutting of rescue vehicle, including casing 1, install go-between 2 through the bearing connected mode on the casing 1, install driven shaft 3 through the mode that the bearing is connected on the inner wall of go-between 2, the left end of driven shaft 3 is fixed with one from driving wheel 4, install No. two from driving wheel 5 through the bearing connected mode on the outer wall of driven shaft 3, install No. two at the left end of go-between 2 from driving wheel 5 through bolted connection's mode, cylinder 6 is installed on the upper portion of casing 1, the right-hand member of cylinder 6 is fixed with connecting plate 7, install sliding shaft 8 through the bearing connected mode on the connecting plate 7, No. one action wheel 9 is installed to sliding shaft 8's left part, No. two action wheels 10 are installed to sliding shaft 8. When the cutting device is used, the air cylinder 6 stretches and retracts to drive the connecting plate 7 to move, the connecting plate 7 drives the sliding shaft 8 to move, the sliding shaft 8 drives the first driving wheel 9 and the second driving wheel 10 to move, the first driving wheel 9 and the second driving wheel 10 are controlled to be respectively meshed with the first driven wheel 4 and the second driven wheel 5, power is provided for the movement of the cutting device and the observation device, and the manufacturing cost is saved.
The left part of casing 1 is installed motor 11, and motor 11 provides power for the rotation of sliding shaft 8, and No. one link 12 is installed to the right-hand member of go-between 2, and No. two links 13 are installed to the right-hand member of driven shaft 3. When the device is used, the first connecting frame 12 is provided with an external cutting device, and the second connecting frame 13 is provided with an external observation device.
A spline housing 14 is fixed on the shaft of the motor 11.
And a spline groove is formed in the inner wall of the sliding shaft 8. In use, the spline housing 14 mates with the spline groove and the spline housing 14 can slide along the spline groove to provide conditions for movement of the sliding shaft 8.
The housing 1 is provided with a window. When in use, the observation is convenient for operators to observe.
The window is made of transparent materials.
When the cutting device is used, the cylinder 6 extends out to drive the connecting plate 7 to move rightwards, the connecting plate 7 drives the sliding shaft 8 to move rightwards, the sliding shaft 8 drives the first driving wheel 9 and the second driving wheel 10 to simultaneously move rightwards, after the second driving wheel 10 moves to a proper position, the second driving wheel 10 is meshed with the second driven wheel 5, the first motor 11 works to drive the sliding shaft 8 to rotate, the sliding shaft 8 drives the second driving wheel 10 to rotate, the second driving wheel 10 drives the second driven wheel 5 to rotate, the second driven wheel 5 drives the connecting ring 2 to rotate, so that the first connecting frame 12 is driven to rotate, the first connecting frame 12 drives the external cutting device to move, and the object is cut,
similarly, motor 11 stop work, when cylinder 6 contracts, drive sliding shaft 8 and remove left, the in-process that sliding shaft 8 removed, No. two action wheels 10 and No. two break away from driving wheel 5, after sliding shaft 8 moved suitable position, action wheel 9 meshed from driving wheel 4 with No. one, at this moment motor 11 work, it is rotatory to drive sliding shaft 8, sliding shaft 8 drives action wheel 9 rotatory No. one, action wheel 9 drives driven wheel 4 rotatory No. one, it is rotatory to drive driven shaft 3 from driving wheel 4, driven shaft 3 drives link 13 rotatory No. two, link 13 drives external viewing device and removes suitable position No. two, cutting device's flexibility has been guaranteed, manpower and materials have been saved.
