Abstract

The invention discloses a novel internal clamping jack and an application method thereof. The novel internal clamping jack comprises a positioning nut, a threading sleeve, a piston, an oil cylinder, atop pressure plate and a tool anchor plate. The threading sleeve is located in the oil cylinder, the piston is mounted between the oil cylinder and the threading sleeve, a sealing plate and a compaction ring as sealing assemblies are successively mounted between the oil cylinder and the piston from inside to outside, the tool anchor plate is mounted at the left end of the inner side of the threading sleeve, and a hole where a single steel strand passes is formed in the tool anchor plate; a force measuring sensor is mounted on the inner side of the threading sleeve.

Description

technical field [0001] The invention relates to a jack, in particular to a novel internal card jack and its usage method. Background technique [0002] The existing internal snap-in jack is basically an integral connection between the tool anchor plate and the jack. During construction, the position of the jack and the position of the working anchor plate cannot be adjusted quickly and conveniently, and the cooperation of the two is required to make the adjustment work As the volume increases, construction difficulties increase. Contents of the invention [0003] The technical problem to be solved by the present invention is a new type of internal card jack and its use method. The miniature self-restoring sensor of the tool clip retraction value component can be disassembled at any time and replaced with each other. The installation and removal are simple and convenient, and can meet the needs of multiple Displacement detection, to meet the use of tension anchors in diffe...
