[0041] It should be noted that each of the above-mentioned electrical devices is electrically connected to the controller 44 .

[0042] The specific working principle of the utility model is as follows: when it is necessary to build a net-sealing spanning frame, first move the crawler vehicle 1 to the construction position, then pull the telescopic frame 2 out to a suitable position, control the telescopic end of the supporting hydraulic cylinder 3 to extend through the controller 44, and then control the driving motor 1 7 to rotate, so that the base 6 rotates to a suitable position. Then, the telescopic ends of the hydraulic cylinder 10 and the hydraulic cylinder 2 14 are controlled to extend through the controller 44, so that the vertical frame 8 is in a vertical state and the telescopic arm is in a horizontal state. Then, the servo motor 3 29-3 in the basic arm 13 is started through the controller 44, so that the first-stage arm 15 extends outward. When the end plate 31-1 on the first-stage arm 15 contacts the contact switch 31-3 on the limit plate 31-2 in the basic arm 13, the controller 44 turns off the servo motor 3 29-3 and energizes the electromagnet at the same time, so that the position between the basic arm 13 and the first-stage arm 15 is fixed, and so on until the final arm 18 is unfolded. After the final arm 18 is unfolded, the controller 44 controls the winding mechanism 19-5 to release the vertical support arm 19 to make it in a vertical state, and then adjusts the position of the main rod 19-8-1 through the electric push rod 19-10 so that the tooth plate 19-8-3 on the main rod 19-8-1 can contact the tooth plate 19-8-3, and then the winding mechanism 19-3 releases the sub-tube 19-2 downward.

[0043] In addition, when the primary arm 15 is extended, under the action of the drive toothed belt 1 25 and the drive toothed belt 2 26, the wings 24-4 in the net-stretching assembly 24 on the basic arm 13 are opened, so that the side rod 24-3 pulls out the protective net 24-8, and so on until the final arm 18 is extended, the wings 24-4 in the net-stretching assembly 24 on the tertiary arm 17 are opened, and the side rod 24-3 pulls out the protective net 24-8.

[0044] It should be noted that when the primary arm 15 is unfolded, the driving rack 28 drives the second gear to rotate, and the second gear drives the first gear to rotate, thereby making the balance arm 27 in a vertical state.

[0045] When the crossing frame needs to be folded, the vertical support arm 19 is folded first, that is, the main rod 19-8-1 in the one-way limit mechanism 19-8 is first retreated by the electric push rod 19-10 so that the tooth plate 19-8-3 is disengaged from the positioning rack 19-7, and then the sub-tube 19-2 is folded by the winding mechanism 1 19-3, and then the vertical support arm 19 is folded into the final arm 18 by the winding mechanism 2 19-5, and then the electromagnet between the final arm 18 and the tertiary arm 17 is first powered off, the final arm 18 is retracted, and then the tertiary arm 17, the secondary arm 16, and the primary arm 15 are retracted one by one.

[0046] It should be noted that when the final arm 18 is retracted, the net assembly 24 on the tertiary arm 17 is stored, and so on until the net assembly 24 of the basic arm 13 is stored. In addition, when the primary arm 15 is retracted, the balance arm 27 gradually tilts down.

[0047] Next, the hydraulic cylinder 1 10 is retracted to cause the vertical frame 8 to fall over, and then the hydraulic cylinder 2 14 is retracted to cause the basic arm 13 to fall toward the vertical frame 8 .

[0048] Finally, the telescopic end of the supporting hydraulic cylinder 3 is retracted, and the telescopic frame 2 is pushed into the crawler vehicle 1.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
