Description

Technical Field

[0001] The utility model relates to the field of bridge construction, in particular to a high pier maintenance device for bridges. Background Art

[0002] When the bridge piers are high, maintenance is more difficult. The existing maintenance method is usually to set up spray brackets around them so that water pipes spray at equal intervals from high to low. The uniformity of spraying is difficult to ensure and it is difficult to meet the maintenance needs. In order to solve the problem of uniform spraying, there is a method of dynamic spraying by moving the platform up and down in the prior art. For example, a spray maintenance device for a variable-diameter bridge high pier disclosed in announcement number CN218521633U and a bridge high pier maintenance device disclosed in announcement number CN213625264U both require a motor to drive a rope to pull the platform up and down. Although this method can achieve uniform spraying, it requires electricity, has high usage and production costs, and there are safety hazards in moving up and down, and its practicality is poor.
