Lever Type Tensile Tester

Abstract

The invention relates to a lever-type tension tester, which is characterized by comprising a tested member fixed on the lower end of a base, wherein the tested member is connected with a tested member connection plate through a connection pin. The lower end of the tested member connection plate is provided with a first connection hole. One side of the tested member is provided with a hydraulic jack. A pressing rod on the upper end of the hydraulic jack bears against the bottom surface of the base. The lower end of the hydraulic jack is a jack seat with a second connection hole. An ejection lever seat is arranged by adopting the tested member as axis, wherein the position of the ejection lever seat and the position of the hydraulic jack are symmetrical. The upper end of the ejection lever seat and an ejection lever form a threaded connection, wherein the upper end of the ejection lever ejects the lower end surface of the base. The lower end of the ejection lever seat is provided with a third connection hole, wherein the first connection hole, the second connection hole and the third connection hole are positioned at the same level height, and are connected with a balance beam. The lever-type tension tester of the present invention has characteristics of simple structure, clever design, and reasonable layout, wherein the lever-type tension tester can perform a tension test on a lifting point after the lifting point is welded on a mega steel structure and other heavy objects.

Description

technical field [0001] The invention relates to a tensile tester, in particular to a lever type tensile tester. Background technique [0002] When it is necessary to lift huge steel structures, such as ship sections, heavy boilers, bridge box girders, etc., several lifting points (eye plates or lifting lugs) need to be welded on the steel structure, and the shackles and heavy crane rigging connect. However, since there is no matching tensile tester after the eye plate or lifting lug is welded to the steel structure, the tensile test cannot be carried out. Seam height and length etc. This often results in a great waste of base metal, welding materials, electric power and manpower. Therefore need a kind of tensile tester that can solve the above-mentioned problem now. Contents of the invention [0003] The present invention is to solve the above-mentioned deficiencies existing in the prior art, and proposes a lever type with simple structure, ingenious design and reasona...
