Surface napping machine for concrete prefabricated part

Abstract

The invention relates to the technical field of concrete prefabricated part machining equipment, and discloses a surface napping machine for a concrete prefabricated part. The surface napping machinecomprises a fixed base, wherein fixed guide rails are installed on the two sides of the upper end of the fixed base; rolling wheels are arranged at the top ends of the fixed guide rails in a sliding mode; connecting shafts are installed between the middles of the rolling wheels; walking plates are installed on the connecting shafts at the two ends of the rolling wheels respectively; a top plate isinstalled at the top ends of the walking plates; a walking frame is installed between the walking plates on the inner side; an upper guide frame is installed at the lower end of the walking frame; afirst guide block is arranged on the left side of the upper guide frame in a sliding mode; the lower end of the first guide block is connected with a stud through a threaded structure; a second guideblock is arranged at the right end of the upper guide frame in a sliding mode; a first connecting rod is hinged to the first guide block; and a second connecting rod is hinged to the second guide block. According to the surface napping machine, the whole device can move front and back along the fixed guide rails, the movement requirement of napping is met, the adjustment of the vertical height ofa napping plate is ensured, and the napping requirements of different depths of concrete prefabricated parts with different thicknesses are met.

Description

technical field [0001] The invention relates to the technical field of concrete prefabricated parts processing equipment, in particular to a surface roughening machine for concrete prefabricated parts. Background technique [0002] Concrete precast parts, also known as PC components, refer to concrete products that are processed and produced in factories through standardized and mechanized methods. Correspondingly, traditional cast-in-place concrete requires on-site molding, on-site pouring and on-site maintenance. Prefabricated concrete is widely used in construction, transportation, water conservancy and other fields, and plays an important role in the national economy. [0003] In the construction industry, the roughening equipment is an important part of the auxiliary equipment of the concrete prefabricated component production line. The roughening machine is used to draw a straight line texture with a certain depth and width on the surface of the initially set prefabri...

Chinese patent (publication number: CN109159265A) discloses a napping machine for concrete prefabricated parts, which is characterized in that it includes: a support stand, the top of which has a longitudinal guide rail arranged along its length; on the top of the support stand, and can move back and forth and lock on the longitudinal moving guide rail, the top of the longitudinal moving trolley has a transverse moving guide rail arranged along its length; the transverse moving trolley is set on the longitudinal moving trolley, and can Move back and forth along the traversing guide rail and lock; the lifting mechanism includes a fixed frame vertically fixed below the traversing trolley and a mobile frame slidingly matched with the fixed frame. The mobile frame can move up and down along the fixed frame by means of a driving structure, although Under certain circumstances, this device can achieve a rapid napping effect on concrete prefabricated parts, but in actual operation, the device has a complex structure, and it cannot quickly adjust the napping depth of prefabricated parts with different thicknesses. Therefore, further research is still needed. improvement of
