The specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiment of a kind of hydraulic support displacement transducer of the utility model dismantling device is done detailed description.
As shown in Figure 1, the hydraulic support displacement transducer dismantling device of the utility model comprises card post 1, fixed block 2 and action bars 3.Card post 1 one ends are cylindrical structural, and the other end is a screw thread, and the centre is one section six square nut structure, and the hole shape of being opened on its shape and the displacement transducer to be removed matches.Like Fig. 3-shown in Figure 6, fixed block 2 is connected to form by first cylinder 21 and second cylinder 22, and the diameter of first cylinder 21 is less than the diameter of second cylinder 22.Side end face that is not connected at first cylinder 21 with second cylinder 22; Promptly first side end face is provided with 23,4 screwed hole 23 centre positions of 4 screwed holes corresponding with displacement transducer position of opening to be removed and mills out an elongated hole 24; Open a flat-shaped through hole 25 in the front and rear part of first cylinder 21; Run through first cylinder 21, and flat-shaped through hole 25 can communicate with elongated hole 24, the end of thread of card post 1 is fixed in the screwed hole 23.Second cylinder 22 has circular radially via hole 26.Action bars 3 is a cylindrical-shaped structure, inserts radially in the via hole 26, and its first end is provided with step 31; The diameter of step 31 is greater than the bore of via hole 26 radially; Second end of action bars 3 is positioned at the radially outside of via hole 26, and the position, intermediate portion is provided with screwed hole 32, can a baffle plate be fixed on (bolt and baffle plate are not shown on figure) on the action bars 3 through a bolt; Baffle plate can't pass radially via hole 26, and the effect of step 31 and baffle plate all is to make the action bars 3 can be from radially not skidding off the via hole 26.
