Specifically, the locating pins 32 are four and are respectively arranged at four corners of the top surface of the supporting seat 1, the rectangular bottom plate 21 is located between the locating pins 32, the width of the rectangular bottom plate 21 is matched with the row spacing of the locating pins 32, and the length of the rectangular bottom plate 21 is matched with the longitudinal spacing of the baffle 31.
Each positioning pin 32 comprises a rotating rod 321, a connecting rod 322 and a limiting rod 323, specifically, the bottom of the rotating rod 321 is rotatably connected with the supporting seat 1, the connecting rod 322 is fixedly installed at the top of the rotating rod 321, and the two can rotate together; the other end of the connecting rod 322 is provided with a vertical through hole, and a limiting rod 323 is movably arranged in the vertical through hole in a penetrating way; in order to prevent the stopper bar 323 from falling off, the stopper bar 323 is provided with anti-falling plates 324 located at both sides of the vertical through hole, and in general, the distance between the anti-falling plates 324 is greater than the depth of the vertical through hole, so that the stopper bar 323 can move up and down within a certain range. When the limiting rod 323 rotates with the rotating rod 321 and the connecting rod 322 at a position outside the rectangular bottom plate 21, it is in a first state, i.e., a non-locking state; when the limiting rod 323 rotates above the rectangular bottom plate 21 along with the rotating rod 321 and the connecting rod 322, and the end of the limiting rod 323 can be correspondingly inserted into the positioning hole 22 at the four corners of the rectangular bottom plate 21, the limiting rod 323 is in the second state, i.e., the locking state. In order to enhance the locking effect, the limiting rod 323 and the positioning hole 22 adopt a threaded connection structure.
Because the bridge floor broad when carrying out the jacking operation, needs a plurality of hydraulic jack 2 antithetical couplets to use usually, consequently, still install dead lever 4 between the adjacent supporting seat 1 for connect the supporting seat 1 that the list set up.
