Embodiment 1

[0043] see Figure 1~3 As shown, a squirrel-cage bridge stay cable overhaul device consists of a squirrel-cage mobile frame 1, a squirrel-cage sheath frame 3, a driving mechanism wire rope 7, a safety lock wire rope 8, a driving mechanism 5, a safety lock 6, and a passenger Chlorophytum 4, cable-stayed lower tie 9, and cable-stayed upper tie 10, wherein the squirrel-cage mobile frame 1 passes through the squirrel-cage sleeves 3 hoops at both ends of the squirrel-cage mobile frame 1 on the cable-stayed cables of the bridge. On 14; one end of the lower tie hoop 9 of the stay cable and the 14 root hoops of the bridge stay cable are fastened with bolts, and one end of the tie hoop 10 on the stay cable and the hoop at the pylons at the top of the two bridge stay cables 14, And fix it with bolts; one end of the driving mechanism steel wire rope 7 is connected and fixed with the upper tie hoop 10 of the stay cable at the pylon, and the other end is connected with the driving mechanis...

Embodiment 2

[0052] see Figure 5 As shown in the figure of another embodiment of the present invention, the two ends of the squirrel cage mobile frame 1 or the upper, middle and lower three places are connected with a squirrel cage sleeve frame 3, which is a detachable polygonal structure, and the hoop is cable-stayed on the bridge. On the cable 14, its driving mechanism is the hoist 15 installed on the deck of the bridge, after one end of the wire rope wound on the hoist 15 passes through the pulley installed on the top of the bridge stay cable 14, it will be connected with the suspension ring provided on the top of the squirrel cage mobile frame 1. Connect and fasten, start winch 15 and can make squirrel-cage mobile frame 1 move up and down along bridge stay cable 14.

Abstract

The invention relates to a cross-river cable-stayed bridge inspection device which is a squirrel-cage type bridge stayed cable inspection device. A squirrel-cage type movable frame is anchored and clamped at a bridge stayed cable by squirrel-cage type stocks at two ends of the squirrel-cage type movable frame. One end of a stayed cable lower strapping hoop is anchored and clamped with the root of the bridge stayed cable and is fastened by a bolt. One end of a stayed cable upper strapping hoop is anchored and clamped with a bridgehead at the tops of two bridge stayed cables. One end of a drive mechanism steel wire rope is connected and fixed with the stayed cable upper strapping hoop at the bridgehead, and the other end passes a first turning pulley of the lower strapping hoop and then is connected with a heavy hammer of the drive mechanism steel wire rope. One end of a safe lock steel wire rope is connected and fixed with the upper strapping hoop, and the other end passes a second turning pulley of the lower strapping hoop and then is connected with the heavy hamper of the safe lock steel wire rope. One end of a drive mechanism is connected with a base plate, and the other end is connected with the drive mechanism steel wire rope. One end of a safe lock is connected with the base plate, and the other end is connected with the safe lock steel wire rope. The cross-river cable-stayed bridge inspection device has the advantages that the cross-river cable-stayed bridge inspection device does not require setting up a lot of scaffolds and has simple structure, low cost and short construction period.

Description

technical field [0001] The invention relates to an overhaul device for a cable-stayed bridge across a river, in particular to a cable-stayed overhaul device for a squirrel-cage bridge. Background technique [0002] With the rapid development of the economy, there are more and more bridges across the river. Among them, the cable-stayed bridges are large in quantity and wide in scope. The anti-corrosion and all-round maintenance of cable-stayed cables has become a top priority. How to climb high and provide simple, safe and convenient maintenance and operation devices It has become a top priority, and there are two maintenance methods used in the past. [0003] 1. Set up scaffolding for maintenance [0004] The advantages are: safe and reliable; [0005] The disadvantages are: (1) The amount of scaffolding is large, and the actual maintenance workload is very small. [0006] (2) The cost of erecting scaffolding is high, the construction period is long, and local road closur...
