[0046] like Figure 5As shown, a first flip positioning plate 25 is provided at the bottom of the mounting plate 36 of the secondary transmission assembly 7.

[0047] The secondary telescopic boom mechanism 8 is slidably disposed on the lower inner side of the primary telescopic boom assembly 5. A folded cloth 9 is attached to the bottom of the secondary telescopic boom mechanism 8 for storing materials, maintenance tools or cleaning fluid.

[0048] like Figure 7 As shown, the secondary telescopic arm mechanism 8 includes two symmetrically arranged secondary telescopic arms 44, which are respectively fixed to the second and third section slide rails 24, allowing the secondary telescopic arm mechanism 8 to slide and extend under the primary telescopic arm mechanism 5.

[0051] In this embodiment, the first rack 18, the primary transmission assembly 2, the tensioning wheel assembly 4, the secondary transmission assembly 7 and the second rack 48 are located on the same side.

[0052] In this embodiment, the fixing methods are all welding or bolt fixing.

[0053] The use process of this embodiment is as follows:

[0054] The device is fixed on the equipment to be protected or protected in the tunnel by the mounting screw 15, and it is in a retracted state when not working, as shown. Figure 1

[0055] When working, under the drive of the motor 28, the first gear 31 walks along the first rack 18, at the same time, the first belt 3 drives the first belt pulley 30, the tensioning wheel 33 and the third belt pulley 42 to rotate, the third belt pulley 42 and the fourth belt pulley 43 rotate coaxially and at the same speed, the fourth belt pulley 43 drives the second belt pulley 40 to rotate through the second belt 6, the rotation of the second belt pulley 40 makes the second gear 37 walk along the second rack 48, in this way, the primary telescopic arm mechanism 5 and the secondary telescopic arm mechanism 8 are gradually expanded, finally, the receiving plate 11 is turned over by 90° under the action of gravity, coplanar with the primary telescopic arm mechanism 5 and the secondary telescopic arm mechanism 8, in an open state.

[0056] ​After the work of receiving the material is finished, the motor 28 reverses, the first gear 31 walks reversely along the first rack 18, the second gear 37 walks reversely along the second rack 48, until the position photoelectric switch trigger plate 32 touches the position photoelectric switch 16, and the impact bearings 50 impact the first and second turnover positioning plates 25 and 26 respectively, so that the receiving plate 11 is folded up, i.e. the whole folding is finished.

[0057] The above describes the utility model by using specific examples, which is only used for helping to understand the utility model, and does not limit the utility model. According to the idea of the utility model, a person skilled in the art of the utility model can make some simple deductions, deformation or replacement.
