[0034] The working process of the present invention is as follows:

[0035] When it is necessary to lay and install the microgrid line, first install the pull bracket 34 to the appropriate position on the threaded pull rod 8 through the nut, lift the bridge frame 1 to the installation position, and then align the through slot on the pull bracket 34 with the baffle 33 and push it so that the baffle 33 passes through the through slot on the pull bracket 34, engage the limit column 28 on the adjacent bridge frame 1 into the slot on the fixing block 23, and place the cable accordingly on the cable positioning mechanism 4, eliminate the lifting force on the bridge frame 1, and complete the connection of the bridge frame 1 and the fixation of the cable.

[0036] The specific working process of each component of the line laying and installation device is as follows:

[0037] When the lifting force on the bridge frame 1 is eliminated, under the action of gravity of the bridge frame 1 and components such as cables, the pull bracket 34 pulls the hanging arm 31, so that the hanging arm 31 drives the rotating shaft 25 to rotate, and the rotating shaft 25 drives the gear 26 to rotate.
