Since the radius of the roll film 8 is continuously reduced as the roll film 8 is discharged, if the constant speed is to be maintained, the rotation speed of the roll film 8, that is, the rotation speed of the variable displacement motor 51, needs to be increased accordingly.

In this embodiment, the film spreading device further comprises a sensor, the sensor is arranged on one side of the first supporting seat 5 and/or the second supporting seat 6 and used for detecting the number of film unwinding turns of the rolled film 8, and the sensor is electrically connected with the controller.

The walking of the walking and transporting device is controlled through the remote controller, the variable motor 51 of the film laying driving mechanism works, the controller realizes the consistent walking speed and film laying speed of the walking and transporting device through intelligent control, and the stability of film laying is improved.

When the film spreading machine finishes film spreading and needs transition, the suspension arm 2 is controlled to rotate through a remote controller, and the film roll 8 is dismounted through the lifting hook 3 and the hanging strip. Then, the upper pin shaft and the lower pin shaft which are arranged between the first folding frame 42 and the fixed frame 41 and far away from one side of the transportation platform 11 are disassembled, the first hydraulic cylinder and the second hydraulic cylinder 45 are controlled to drive the first folding frame 42 and the second folding frame 43 to rotate for 90 degrees, so that the first folding frame 42 and the second folding frame 43 are parallel to the side face of the body of the crawler-type transportation vehicle 1, the first folding frame 42 and the second folding frame 43 are fixed on the body through bolts, good passing performance is achieved when the film laying machine is turned, and safety is guaranteed.

Example two

The difference between this embodiment and the first embodiment is:

as shown in fig. 5, the first folding frame 42 and the second folding frame 43 of the roll film supporting frame in this embodiment are both folded upwards, and the first hydraulic cylinder 44 and the second hydraulic cylinder 45 are both fixed on the same side of the fixing frame 41 through the fixing seat. The first folding frame 42 and the second folding frame 43 are connected through a hinge shaft 912 or a hinge, so that the first folding frame 42 rotates around the hinge shaft 912 or the hinge by 90 degrees under the driving of the first hydraulic cylinder 44 to realize folding or unfolding; the second folding frame 43 is driven by the second hydraulic cylinder 45 to rotate 90 degrees around the hinge shaft 912 or the hinge, so as to be folded or unfolded. The fixing frame 41, the first folding frame 42 and the second folding frame 43 are rectangular frames.

In another alternative embodiment of the present invention, the film roll supporting frame may also be configured as a telescopic structure, and includes a fixed frame 41, and a first telescopic frame and a second telescopic frame connected to two ends of the fixed frame 41, wherein the first supporting seat 5 is disposed at an end of the first telescopic frame away from the fixed frame 41, and the second supporting seat 6 is disposed at an end of the second telescopic frame away from the fixed frame 41. The telescopic structure can be in a sleeved connection or other forms.

The above description is only a preferred embodiment of the present invention, and for those skilled in the art, the present invention should not be limited by the description of the present invention, which should be interpreted as a limitation.
