The anchor component 134 includes a connecting rod 1341 and a lifting ring 1342. The connecting rod 1341 is coaxial with the connecting shaft 1321. The connecting rod 1341 adopts a galvanized square steel pipe with a specification of 40mm*40mm*3mm. The first end of the connecting rod 1341 is connected to the second end of the connecting shaft 1321, and the second end of the connecting rod 1341 is used for connecting the track system 1 and the protection system 2. The first end and the second end of the connecting rod 1341 are in pairs, and a lifting ring 1342 is arranged on the connecting rod 1341. The lifting ring 1342 adopts a smooth round steel bar with a diameter of 12mm, and the lifting ring 1342 is used for connecting the track system 1 and the lifting system 3.

[0037] The connecting rod 1341 is also provided with a cross bar 135, and the cross bar 135 includes a cross bar 1351 and a cross bar 1352.
