detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 1-4 is high speed ballastless turnout composite eccentric described in the utility model cover special dismounting facility, comprises bracing frame 11, handle 13, conicity locking device 14; Support frame as described above 11 is used for covering track switch skateboard component 1; The side of support frame as described above 11 is provided with support column 12; The middle part hinge of described handle 13 is at the top of support column 12; The inner of described handle 13 is provided with conicity locking device 14; Described conicity locking device 14 can insert in the through hole of the composite eccentric cover 2 on track switch skateboard component 1; Described conicity locking device 14, comprises joint pin 141, tapering connecting rod 142, spring 143, locking flange 144; Described joint pin 141 is for the connection of the inner with handle 13, so that when pressing the outer end of handle 13, handle 13 can rotate around support column 12, and lifts joint pin 141; One end of described tapering connecting rod 142 is provided with screw thread, for the connection with joint pin 141; The external diameter of the other end of described tapering connecting rod 142 increases gradually; Described locking flange 144 is set on tapering connecting rod 142; The soffit of described locking flange 144 is provided with trepanning 145; The sidewall of described trepanning 145 is provided with steel ball 146 symmetrically; When moving under steel ball 146 is super along the outer wall of tapering connecting rod 142, can by the outer wall spreading of trepanning 145; Described spring 143 is set on tapering connecting rod 142, and is arranged between the soffit of joint pin 141 and the upper surface of locking flange 144; The bottom of described tapering connecting rod 142 is provided with expansion section 147; The external diameter of described expansion section 147 is greater than the internal diameter of trepanning 145, and during to prevent work, steel ball 146 is deviate from from tapering connecting rod when tapering connecting rod 142 moves.
As accompanying drawing 3, shown in 4, during use, the relative joint pin 141 of locking flange 144 is first made to move, the trepanning 145 of locking flange 144 is made to be in non-spreading state, namely conicity locking device 14 is in insert state, and make the locking flange 144 of conicity locking device 14 insert in the through hole of composite eccentric cover 2, press the outer end of handle 13 again, the joint pin 141 to conicity locking device 14 can be realized, tapering connecting rod 142 is also along with lifting simultaneously, now steel ball 146 moves relatively down along the outer wall of tapering connecting rod 142, thus the spreading realized the outer wall of trepanning 145, when the outer wall of trepanning 145 spreading to a certain degree time, the clamping of the through hole to composite eccentric cover 2 can be realized, now press the outer end of handle again, composite eccentric can be overlapped 2 to extract from track switch skateboard component 1.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The conicity locking apparatus structure of high speed ballastless turnout composite eccentric cover special dismounting facility described in the utility model is simple, conveniently can clamp the through hole of composite eccentric cover, easily composite eccentric cover can be extracted from track switch skateboard component by lever principle again, laborsaving, and removal efficiency is high.
Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
