The invention relates to an intelligent front clamping lifting jack with a direct force measuring function. The intelligent front clamping lifting jack comprises a displacement sensor, an oil cylinder, a hollow wrap, a support cylinder, a front clamping tool anchor and a baffle, wherein the outer diameter of the support cylinder at the front end is smaller than that of the oil cylinder; the front clamping tool anchor is arranged at the front end of the lifting jack; a force measuring sensor is mounted on the wall of the support cylinder; the force measuring sensor sends out the data measured so as to be conveniently used for measuring deformation data of the stressed support cylinder. The intelligent front clamping lifting jack with the direct force measuring function has the advantages as follows: the real-time digital display of the tension elongation is achieved through the displacement sensor, the stress on the support cylinder by the lifting jack is directly measured in real time through the force measuring sensor, so that the data measured is accurate, the tension quality is effectively improved, the structure is simple, the use is convenient, the front end outer diameter of the lifting jack is small, the problem of prestress tension with space constraints is solved, the front clamping tool anchor is arranged at the front end of the lifting jack, pre-stressed steel strands used for tension construction are economized, the structure is simple, and the installation and maintenance are convenient.
