Abstract

The invention provides a novel rope tensioning device with double hydraulic cylinders. The novel rope tensioning device with double hydraulic cylinders comprises a tightening block and a stabilizing block, wherein the tightening block is provided with two rope penetrating channels; the stabilizing block is provided with two rope fixing channels which correspond to the two rope penetrating channels; a pressing screw for fixing a rope is arranged on each rope fixing channel; two oil injection holes are formed in the stabilizing block in parallel; a piston rod is arranged in each oil injection hole; a sealing piece is arranged between each piston rod and the inner wall of the corresponding oil injection hole; and after extending out of the stabilizing block, the top ends of the piston rods are connected with the tightening blocks. According to the novel rope tensioning device with the double hydraulic cylinders, the distance between the tightening block and the stabilizing block is changed through a hydraulic structure, then the rope is tightened, under the effect of a hydraulic structure, acting force can be applied to a steel wire rope at constant speed, due to uniform stress, breakage of the steel wire rope or a puller strap due to severe local stress can be avoided, and thus, smooth rope tensioning is ensured.

Description

technical field [0001] The invention belongs to the technical field of rope tensioning, and in particular relates to a novel double hydraulic cylinder rope tensioning device. Background technique [0002] During the transportation or storage of various hazardous chemical media, pipes, flanges, tanks, etc. are gradually corroded and aged, and leaks are prone to occur. It is necessary to repair and plug leaks in time to reduce losses and avoid hazards. In the prior art, some use the fastening plugging method, that is, use the tightening of the tension belt or the steel wire rope to generate force to press the sealing layer tightly on the leak to achieve a final balanced plugging method; The rope device often causes the rope to break due to the uneven stress on the rope, which then affects the sealing. Contents of the invention [0003] In view of this, the present invention aims to propose a novel double-hydraulic-cylinder rope tensioning device to ensure that the tensionin...
