Crack repairing device for reinforced concrete drainage pipe manufacturing

Abstract

The invention discloses a crack repairing device for reinforced concrete drainage pipe manufacturing. The crack repairing device comprises a movable plate trailer, the top of the movable plate trailer is connected to an air compressor, a placing box, an electric box and a supporting frame through bolts, wherein the top of the supporting frame is connected to an air storage tank through bolts, the air outlet end of the air compressor communicates with the air storage tank through an air pipe, two cavities are formed inside the placing box, and cementing barrel placing frames and repairing mechanisms are arranged on the inner sides of the two cavities correspondingly. According to the crack repairing device, through arrangement of the air compressor, the air storage tank, the placing box and the repairing mechanism, the cementing barrel is convenient to replace, and the cementing material injection strength is further reduced, a cementing material injection head is arranged to change the cementing material injection speed according to the size of a crack, then the cementing material injection efficiency is improved, and through arrangement of an air injection assembly, the technical problems that the cleaning effect is not ideal and the repairing effect is not facilitated due to the fact that the interior of the crack is cleaned through airflow and impurities cannot be removed from the crack after cleaning are solved.

Description

technical field [0001] The invention relates to the technical field of reinforced concrete drainage pipe production, in particular to a crack repairing device for the manufacture of reinforced concrete drainage pipes. Background technique [0002] Drainage pipes are mainly responsible for the drainage of rainwater, sewage, farmland irrigation and drainage. Drainage pipes are divided into plastic drainage pipes, concrete pipes and reinforced concrete pipes, but reinforced concrete drainage pipes tend to have cracks after production. [0003] In the process of repairing harmful cracks in concrete structures, a syringe-type glue injector is usually used. When using it, workers hold the glue injector to inject glue into the cracks; When repairing cracks in large concrete structures, the amount of glue injected is relatively large. Due to the small volume of the syringe type glue injector, the number of glue injections is large, and glue needs to be added frequently, which is tr...

[0003] In the process of repairing harmful cracks in concrete structures, a syringe-type glue injector is usually used. When using it, the worker holds the glue injector to inject glue into the crack; when encountering When repairing cracks in concrete structures with a large number of cracks or wide cracks, large crack lengths and deep cracks, the amount of glue injected is relatively large. Due to the small volume of the syringe type glue injector, the number of glue injections is large, and frequent injections are required. It is troublesome to add glue and replace it; but usually, there are a lot of sand and gravel beside the concrete cracks. Before using the glue gun to repair, the staff need to clean the concrete that needs to be repaired first, and then carry out the repair work, so that the staff can be in It needs to run back and forth during operation to extract the cleaning device or glue gun, which takes a lot of time and reduces work efficiency

In order to solve the above problems, the existing Chinese patent with the publication number CN207436535U discloses a convenient concrete crack repair device, including a glue gun, the glue gun is provided with a mounting frame, and the mounting frame is provided with a cleaning device; The cleaning device includes a connecting rod rotatably connected to the mounting frame, on which a cleaning brush is inserted, and the mounting frame is provided with a driving assembly for driving the connecting rod to rotate to drive the cleaning brush to rotate, but the device Although the cleaning device is added, it is difficult to clean the dust and concrete debris inside the gap with a brush, and the impurities after cleaning cannot remove the crack, so the cleaning effect is not ideal, which is not conducive to the repair effect
