The force sensor VI, the lifting platform bracket VII and the bottom plate C are connected into a whole by means of a bracket fixing plate VIII and a punching triangle IX. As shown in fig. 9, a face M7 on the bracket fixing plate is designed in a manner consistent with the design of the bottom support plate III1 and the side support plate IV1, grooves C4 and C5 are formed in the face M, the widths of the grooves C4 and C5 are matched with the sizes of the threaded holes K515, K516, K517 and K518 on the bottom plate C, the positions of the grooves C4 and C5 and the threaded holes K515, K516, K517 and K518 are matched, bolts are placed in the grooves, and the bottom plate C is connected with the bracket fixing plate VIII by the bolts and the spacers. And (3) drilling threaded through holes K801, K802, K803 and K804 on a connecting surface M8 on the bracket fixing plate, sequentially corresponding to four threaded holes on the side surface of the lifting platform bracket, inserting bolts into the two corresponding threaded holes, screwing the bolts, and fixing the bracket fixing plate VIII on the lifting platform bracket VII. The lifting platform support VII is fixed on the base plate C, the rocker Q is arranged at the top, the rocker Q is shaken to drive the lifting platform W to move up and down, and the lifting platform W is adjusted to reach a proper height. The punching triangular plate IX is installed on the lifting platform W and plays a role in connecting the force sensor VI with the lifting platform support VII. As shown in fig. 10, on the connection surface M9 of the punching triangle IX, threaded through holes K901, K902, K903 and K904 correspond to four threaded holes on the side surface of the lifting table W in sequence, bolts are inserted into the threaded holes corresponding to each other two by two, and the lifting table W and the punching triangle IX are fixed together by tightening the bolts. The other connecting surface M10 of the punching triangular plate IX is a triangular thin plate, and a threaded through hole K1001 is punched at the vertex of the triangular thin plate. Inserting a bolt R1 into the threaded through hole K1001, winding a cable at one end of the force sensor VI on the bolt R1, fixing the cable by using a nut X1, enabling the tail end E of the other cable of the sensor to be in contact with the tail end of the cable member, converting the stress condition of the cable member into an electric signal through the force sensor VI, and judging whether the cable member reaches the specified pre-tightening force in the tensioning process through a display D connected with the force sensor VI.
Due to the structural symmetry of the triangular prism-shaped fixed die I, the end pole cord fixing structure V1, the end pole cord fixing structure V2, the end pole cord fixing structure V3, the end pole cord fixing structure V4, the end pole cord fixing structure V5, and the end pole cord fixing structure V6 installed at the ends of the pole members G1, G2, and G3 are identical in structure. As shown in fig. 11, the end rod and cable fixing structure V1 is composed of a regular hexagonal hollow sleeve 1, a bolt R2, a nut X2, and a nut X3. Wherein, the part matched with the bolt R2 in the regular hexagon hollow sleeve 1 is tapped. The nut X2 and the nut X3 are matched with the bolt R2, the bolt R2 is inserted into the regular hexagon hollow sleeve 1, and the nut X2 is screwed down to enable the bolt R2 to be tightly matched with the regular hexagon sleeve 1. One end of the cable component S1 is wound on the bolt R2, the nut X3 is screwed to fix the cable component S1, the other end of the cable component S1 is tensioned, and when the cable component S1 reaches a preset tensioning force, the other end of the cable component S1 is fixed in the above mode, so that the fixed-force tensioning of the cable component can be realized.
The above examples illustrate the technical conception and the structural characteristics of the present patent, in order to make the present patent known to the researchers and engineers working in this field and to enable them to realize the product accordingly.
