Transverse galling machine and galling treatment method

Abstract

The invention discloses a transverse galling machine and a galling treatment method. The transverse galling machine comprises a walking frame moving the back forward along the longitudinal length direction of a to-be-galled area, a work rack mounted on the walking frame, a transverse move frame that is laid on the work rack and can make leftward and rightward transverse movement on the work rack, a transverse move driving mechanism driving the transverse move frame to do leftward and rightward transverse movement, and a galling tool that is driven by the transverse move frame to do leftward and rightward transverse movement synchronously and conducts transverse galling treatment on a to-be-galled area in the leftward and rightward transverse movement process. The galling treatment method includes: 1. determination of the galling treatment time: determining the galling treatment time of the to-be-galled area; and 2. transverse galling treatment, which consists the process of: 201. putting the transverse galling machine in place; and 202. carrying out transverse galling treatment. The transverse galling machine and the galling treatment method provided by the invention have the advantages of reasonable design, convenient realization and good use effect, can simple and rapidly complete the transverse galling treatment process of the to-be-galled area, and have good galling treatment effect.

Description

technical field [0001] The invention belongs to the technical field of bridge deck construction, and in particular relates to a transverse napping machine and a napping treatment method. Background technique [0002] During the construction of highways and bridges, it is often necessary to roughen the road surface or bridge surface. The roughening treatment is mainly used for the combination of new and old concrete. A layer of cement paste, and then the above concrete. For railway passenger dedicated lines using CRTSⅢ slab ballastless track, the CRTSⅢ track slab has higher requirements on the overall stability of the ballast bed. Relevant data show that if the concrete stubble surface is a natural plane shear strength, it is difficult to meet the requirements. Requirements, only after the roughening treatment, the interlocking force and friction of the bridge deck concrete and the concrete layer of the track slab base are greatly improved. Therefore, the roughening treatme...

AI Technical Summary

Problems solved by technology

Among them, when simple tools such as brooms, brushes, and wire brushes are used for roughening, the control of the initial setting time of the concrete has a greater impact on the roughening, and it is easy to cause damage to the surface concrete structure if it is too early. , can not achieve the effect of pulling; to improve the quality of pulling, it is necessary to master the best pulling time of concrete, and at least 8 people are required to carry out the pulling work at the same time

When adopting a simple roughening tool for roughening, the roughening tool mainly uses multiple cutting teeth arranged in parallel for roughening. However, in actual construction, there are problems such as uneven roughening spacing and poor control of depth. Too deep will cause the structure of the concrete protective layer. Destroyed, the overall effect is rough; and, the post-processing effect of chiseling is not good

When chiseling in the later stage, use a chisel hammer or a milling machine for chisel processing. Although the chisel hammer is cheap, it is only suitable for chiseling small areas and consumes a lot of manpower; the milling machine is suitable for large-area concrete surfaces. Gross, but equipment cost and maintenance investment are high

To sum up, the existing napping treatment equipment and methods all have problems such as inability to complete the napping treatment at one time, poor napping effect, and subsequent chiseling treatment to varying degrees. The disadvantage is that it will destroy the protective layer structure of reinforced concrete
