Problems solved by technology

However, when using the horizontal projection method, the projection port must always be aligned with the centerline of the pipe, but the diameter of the steel pipe is variable, so it is difficult to adjust the alignment between the projection port and the centerline of the pipe, and during the projection process, the concrete Affected by gravity, there will be a certain drop

Abstract

The invention discloses a coating trolley lifting height adjusting device. The coating trolley lifting height adjusting device specifically comprises a trolley, a hydraulic cylinder, a pedestal guide groove, a screw rod wheel table, a screw rod wheel, a screw rod, a clutch and hand wheels, wherein the hydraulic cylinder is arranged on the trolley to lift the height of the trolley; a first tabletop is supported on the hydraulic cylinder; a pedestal guide groove is formed in the first tabletop; two screw rod wheel tables are arranged in the pedestal guide groove; a screw rod wheel is arranged on each screw rod wheel table; the two screw rod wheels are connected through two screw rods; the clutch is connected between the two screw rods, so that the distance between the two screw rod wheels is adjusted; one hand wheel is arranged at the outer end of each screw rod. The device can adjust the spraying height of a pipeline, so that no matter how the caliber size is changed, the spraying height and a spraying central point are always kept fixed, the attachment rate of concrete during pipeline coating is greatly improved, and waste of a material can be effectively reduced, and the coating thickness of a pipeline concrete counterweight layer is increased.

Description

technical field [0001] The invention belongs to the field of pipeline counterweight production equipment, and in particular relates to a device for adjusting the lifting height of a coating trolley. Background technique [0002] Due to the influence of the marine environment, there will be drift due to buoyancy during the laying of marine pipelines, and it is necessary to prevent them from being damaged by external factors (such as anchors and tides) during the operation of marine pipelines. Therefore, while anti-corrosion is carried out on marine pipelines, it is also necessary to carry out effective counterweights to overcome the buoyancy of seawater and provide effective mechanical protection. [0003] At present, in China, the concrete counterweight technology for marine pipelines is not perfect. For example, in the Yellow River crossing project of the Ma-Hui-Ning pipeline, the mold method is used for the construction of pipeline concrete counterweights, which has low pr...
