Screw turning machine for segment impermeability test bed

Abstract

The invention relates to a screw turning machine for a segment impermeability test bed. The screw turning machine for the segment impermeability test bed comprises a rack, the upper side of the rack is provided with a lifting hole for a crane to lift so as to transversely suspend the rack above a segment. Two nut screwing mechanisms are fixed to the lower side of the rack and are arranged side byside at an interval along the extending direction of the rack. The nut screwing mechanism comprises a screwing head extending downwards. The two screwing heads are used for being arranged on the nutsat the two ends of the same fastening cross rod in a sleeving mode correspondingly. The nut screwing mechanism is further provided with a driving motor, the driving motor is in transmission connectionwith a driving shaft, the screwing head is matched with the driving shaft in a rotation stopping mode, and the nut screwing mechanism further comprises a controller which is in control connection with the driving motor so as to control the driving motor to rotate forwards and backwards. The operation is simple, the structure is exquisite, and use is convenient.

Description

technical field [0001] The invention relates to a screw-tightening machine for a segment anti-seepage test bench. Background technique [0002] After the segment is manufactured, it is necessary to select a fixed number of segments for a series of tests to ensure the qualification of the segment, which mainly includes the grouting hole pullout test, the segment bending test, the segment impermeability test, etc. , for the segment impermeability test, such as figure 1 As shown, the test is mainly to check whether the impermeability of the segment concrete meets the design requirements, so as to provide a basis for the durability of the segment. [0003] The main test tools for segment impermeability test are: figure 1 As shown, it includes a leak detection frame, a fastening cross bar 12, a double-ended screw 13 and a nut 16, wherein the leak detection frame includes an arc-shaped steel plate 14 whose shape is consistent with the segment, and rubber is installed around the ...
