Abstract

The invention provides a manual tightening device and large-caliber non-standard threaded manual mounting and demounting equipment. The problems that when an existing threaded tool is mounted, the production efficiency is low, a large operation space is needed, and threads of the tool are extremely likely to be damaged are solved. The manual tightening device comprises a threaded tool grabbing unit, a threaded tool adjusting unit, a manual tightening unit and a manual driving unit. The threaded tool grabbing unit comprises a tool V-shaped support, tool clamping cylinders and tool clamping arms. The tool V-shaped support is arranged on the threaded tool adjusting unit, and the threaded tool adjusting unit is used for achieving three-dimensional position adjustment of the tool V-shaped support. The two tool clamping cylinders are arranged on the two sides of the tool V-shaped support correspondingly, and rotary shafts of the tool clamping cylinders are connected with the tool clamping arm. The tool clamping arms are used for clamping the threaded tool. The manual tightening unit is used for achieving clamping of the threaded tool and comprises a tightening frame, a worm reducer, a rotary disc, a clamping finger, a tightening hand wheel and a follow-up assembly. The manual driving unit is used for driving the manual tightening unit to move front and back.

Description

technical field

[0001] The invention relates to thread assembly and disassembly equipment, in particular to a manual tightening device and large-diameter non-standard thread manual assembly and disassembly equipment. Background technique

[0002] In the field of fluid transportation, fluids are usually filled in high-strength thin-walled pressure tubes for transportation, especially when transporting some toxic, harmful and flammable fluids, high-strength thin-walled pressure tubes become the first choice. In order to improve the transportation efficiency and adapt to the transportation of different types of fluids, it is required that the pressure pipes can be spliced ​​at will, especially when toxic and harmful industrial wastes are deeply buried, the demand for this type of seamless pressure pipes is more urgent. Due to the difference of the conveying medium, the length and diameter of the pressure pipe vary greatly.

[0003] When high-strength seamless pressure pipes ar...
