Embodiment Construction
[0020] The present invention will be further described below in conjunction with specific embodiments. Wherein the drawings are only for exemplary illustration, showing merely schematic physical map rather than not to be construed as limiting of the present patent; To better illustrate embodiments of the present invention, the drawings have omitted some components, zoom in or out, do not represent the actual size of the product; the skilled person, the drawings and description of some well-known structures may be omitted it can be appreciated.
[0021] like Figure 1-4 , The hydraulic drill stem testing apparatus of the present embodiment one of the monomers mentioned embodiment, and comprises a pressure test assembly 12 on the rod assembly, wherein the two rod assembly 2 pressure test assembly is symmetrically disposed intermediate 1, for a pressure test is completed the drill rod assembly (not shown) and the drill pipe sealed at both ends a seal pressure test, the rod assembly 2 ...

The invention belongs to the technical field of mechanical design, and discloses a single drill rod water pressure testing device which comprises an upper rod assembly used for placing a drill rod and water pressure testing assemblies symmetrically arranged at the two ends of the upper rod assembly, and each water pressure testing assembly is composed of a base, a sliding rail seat, a thrust oil cylinder, a water inlet connector assembly and a base. The upper rod assembly is composed of a bottom plate, a guide plate, a lifting frame, a lifting oil cylinder, a stand column and a material lifting plate. The single drill rod water pressure testing device is mainly used for smoothly placing the drill rod to the corresponding height, sealing the two ends of the drill rod and injecting high-pressure water between the inner pipe and the outer pipe of the drill rod so as to judge the sealing performance of joints at the two ends of the drill rod by testing the resistance value between the inner pipe and the outer pipe of the drill rod; meanwhile, mechanization of ascending and descending of the drill rod is achieved, manual operation is avoided, labor intensity is reduced, and efficiency is improved.
Description
Technical field [0001] The present invention belongs to the technical field of mechanical design, particularly to a hydraulic drill stem testing apparatus monomer, used in coal hydraulic drill. Background technique [0002] At present, the monomer pressure test rod is manually threaded with the threaded ends of the pipe clamp tight drill, drill take a long, sealed and connected across the inlet connector, and high-pressure water is injected between the inner and outer tubes tested resistance value so as to determine sealability of the tool joint ends. However, with increasing diameters, coal drilling, drill pipe specification also will be getting bigger and heavier. Lead to real dimensions because the drill pipe is too large, emphasis on quality, resulting in difficult handling manual, inefficient, labor-intensive, and the pipe clamp drill when the drill pipe outer spiral groove easily pinch, there are products quality problems, can not meet the development of the drill pipe. In...
