Abstract

The invention discloses a down-the-hole drill carriage assembly, comprising a rack (1), a cylinder (2), a sliding seat (3), a positioning frame (4), two front mandrils (5), two pull rods (6), a pull rod connecting plate (7), a plurality of pipe clamps (8), a plurality of nuts (9), and a plurality of bolts (10). The assembly is characterized in that the rack (1) comprises a rear connecting plate (11), two guide rails (12), a middle connecting plate (13), a front connecting plate (14), and a rib plate (15). The cylinder (2) comprises a cylinder outer barrel (21), a cylinder cover (22), a cylinder screw (23), and a piston rod (24). The sliding seat (3) comprises a sliding plate (31), two symmetric front guide assemblies (33), two symmetric rear guide assemblies (34), and a plurality of sliding seat screws (32). The down-the-hole drill carriage assembly is simple in operation, convenient in installation, good in wear-resisting property, low in noise, high in operation reliability, and long in service life.

Description

technical field [0001] The invention relates to pneumatic rock drilling equipment, in particular to a sliding frame assembly of a down-the-hole drilling machine. Background technique [0002] The guide rail of the carriage assembly of the existing down-the-hole drilling rig is made of channel steel, which is easy to wear, has low positioning accuracy, and unstable work; the cylinder of the carriage assembly is integrally installed on the frame with screws, resulting in The jitter is relatively large, and the noise is large, and the hole drilled has a large error; while the pipe clip of the carriage assembly adopts a fixed structure, when using, the support pipe needs to be inserted into the hole of the pipe clip, and the operation Troublesome and not safe. Contents of the invention [0003] The object of the present invention is to provide a down-the-hole drilling rig carriage assembly with simple operation, convenient installation, good wear resistance, low noise, high w...
