Description
Technical field
The utility model relates to the railway track Inspection equipment, especially relates to a kind of quick rotation direction formula emergency unload rail anchor clamps.
Background technology
Electric concentrated track circuit shunting badness is the major hidden danger that railway transportation is produced, so-called track circuit shunting badness is exactly " pressing not dead ", " the losing car " or " white light band " that is commonly called as, that is: when train enters a certain track section, the track relay of respective segments but still be in the state of picking up or the time state that falls when inhaling, can show green light and white lamp this moment mistakenly on corresponding signal lamp and the control desk, show that this track circuit has lost the function that the track section seizure condition is checked.When such situation took place, train operator and making station control personnel will think that no car takies in this track section by mistake, drove a vehicle and handled the route operation, thereby cause serious train operation accidents such as train collides, crowded trouble, derailing.
Be head it off, railway competent authorities require to detect track circuit shunting badness and should use track circuit level pressure (24.5kN) shunting sensitivity tester and the actual two kinds of means of test of delaying unloading to carry out, there is a kind of residual voltage be higher than " railway signal maintenance regulation " required standard in two kinds of test method, is considered as this section shunting badness.
Track circuit level pressure (24.5kN) is though the rail anchor clamps of shunting sensitivity tester have the advantage that clamping is firm, pressure sensing is accurate, simple to operate, but when it will have train to pass through on running into the rail that emergency situation promptly testing, because the clamping of rail anchor clamps gets too firm, and unloading is relatively more difficult, therefore the staff is difficult within a short period of time the rail anchor clamps be unloaded from rail, thereby causes serious train operation accident to take place.
Summary of the invention
The purpose of this utility model is to provide a kind of simple to operate, efficient and convenient, safe and reliable quick rotation direction formula emergency unload rail anchor clamps, in when, in the use emergency situation taking place at the scene, the staff can carry out emergency handling within a short period of time, apace these rail anchor clamps are unloaded from rail, guarantee traffic safety.
The purpose of this utility model is achieved in that
A kind of quick rotation direction formula emergency unload rail anchor clamps, comprise boosting-rod, orientation lever, the power transmission screw rod, in the pressure test piece of pressure sensor and fixing grab are housed, hooked fixedly grab is by the perpendicular arm of the left flat that is connected as a single entity, transverse arm, right vertical arm and right grab are formed, the rotation of power transmission screw rod also is inserted in the middle vertical screw of transverse arm, top at the power transmission screw rod is fixed with sleeve pipe, be fixed with the pressure test piece in the bottom of power transmission screw rod, sleeve pipe is passed in the boosting-rod activity, sidewall at the pressure test piece is provided with the shunt resistance interface, bottom center at the pressure test piece is provided with the test tread, feature is: movable grab is made up of with the left grab that is positioned at the below the perpendicular arm of " Y " shape that is positioned at the top that is connected as a single entity, fixedly the perpendicular arm of the left flat of grab is placed in " U " shape groove of the perpendicular arm of " Y " shape of movable grab, bearing pin passes the upper end of the perpendicular arm of " Y " shape and the perpendicular arm of left flat from the front upper end with movable grab and fixedly grab be movably connected, make movable grab fixedly rotating on the grab around bearing pin; On the lateral wall of the perpendicular arm of left flat, be equipped with can rotate at perpendicular, the hand of flat twists the rotation direction bolt, the width that is the stubborn rotation direction bolt of hand is slightly less than the width that left flat erects the lateral wall of arm, and the length of the stubborn rotation direction bolt of hand is then erected the width of the lateral wall of arm greater than left flat.
The utility model is to improve on the basis of conventional rail anchor clamps, set up movable grab and hand and twisted the rotation direction bolt, and the width that hand is twisted the rotation direction bolt is slightly less than the width that left flat erects the lateral wall of arm, the length of the stubborn rotation direction bolt of hand is then erected the width of the lateral wall of arm greater than left flat, like this, be convenient to movable trip and outwards deviate from from the perpendicular arm of left flat, the rail anchor clamps break away from rail.To determine track circuit shunting residual voltage test position during use earlier, again the shunt resistance select switch is placed required gear (0.06 Ω or 0.15 Ω), the sensor test line that two rail anchor clamps are used is connected respectively with about the tester main frame, open " source switch ", school zero, again two rail anchor clamps are installed in respectively on two one steel rails, the position that pressure sensor is pressed on rail is close two rails inboard, when promptly travelling and the impression place of rail generation near wheel, simultaneously the hand in the movable trip outside is twisted 90 ° of rotation direction bolt dextrorotations to level, push down movable trip (as Fig. 1, shown in 3), can begin test operation; The rotation boosting-rod is exerted pressure to instrument to rail and is shown as 24.5KN, the other end of sensor test line is connected with the shunt resistance interface of rail anchor clamps tightens, and can detect track circuit shunting residual voltage situation, reads the branch current of track circuit.After test finished, the PTO Power Take Off switch disconnected shunt resistance, and the dowel bar screw thread is unclamped several buttons, and 90 ° on the stubborn rotation direction bolt of derotation hand is extremely vertical, and movable trip is outwards deviate from (shown in Fig. 2,4) from the perpendicular arm of left flat, can unload the rail anchor clamps.When in test process, in the time of will having train to pass through on the rail of testing, and the rail anchor clamps are can not break away from rail the time, available boosting-rod or spanner are twisted the rotation direction bolt with hand and are pressed emergency unload arrow direction indication half-twist to vertical, movable trip can outwards be deviate from from the perpendicular arm of left flat, realizes emergency unload.
Therefore, the utlity model has in the use at the scene that the staff can carry out emergency handling, apace these rail anchor clamps is unloaded, guarantees that from rail traffic safety is simple to operate, efficient and convenient, safe and reliable, advantage of simple structure within a short period of time when emergency situation took place.
