Accompanying drawing 2 looks up structural representation for this utility model；

In the accompanying drawings: collar tie beam on 1,2 bracing wires, 3 thumb wheels, 31 shifting blocks, 4 reflectors, 41 rotating shafts, 5 photoswitches, 6 fix axle, 7 clamping limbs, 8 extension springs, 9 guide wheels, 91 directive wheels, 92 spindle guides wheels.

Detailed description of the invention

Further details of narration is carried out below in conjunction with 1,2 pairs of this utility model of accompanying drawing.

As shown in accompanying drawing 1,2, a kind of clamping limb dibit sensor, it includes thumb wheel 3, the bracing wire 2 being wrapped on thumb wheel 3 and clamping device, the reflector 4 being arranged on collar tie beam 1 and the photoswitch 5 corresponding with reflector 4；Described bracing wire 2 one end is fixing with upper collar tie beam 1 to be connected, the other end is connected by extension spring 8 is fixing with upper collar tie beam 1, described thumb wheel 3 side is provided with shifting block 31, described reflector 4 is arranged on collar tie beam 1 by rotating shaft 41, it is provided with return spring between described reflector 4 and upper collar tie beam 1, being symmetrically arranged with four guide wheels 9 along two clamping limb 7 line of symmetries bottom two clamping limbs 7 of described clamping device, described bracing wire 2 sequentially passes through four described guide wheels 9.

Four described guide wheels 9 include two directive wheels 91 and two spindle guide wheels 92, and described spindle guide wheel 92 is arranged on the arm pivoted fixing axle 6 of clamping.Being arranged in rotating shaft 6 formation spindle guide wheel 92 for saving two, space guide wheel 9, other two is directive wheel 91.

During use, owing to four groups of device work process principles are identical, therefore describe the work process of one group of device, eight paired being arranged on collar tie beam 1 of clamping device, and engagement two-by-two is for clamping the four wheels of vehicle；nullClamping limb 7 opens when position to be held，Obtain system instruction carry out holding action after，Telescopic shaft drives slide block to drive clamping limb 7 to close up clamping tire around respective rotating shaft 6，There is the change of relative position in the position between four guide wheels 9 being now fixed on clamping limb 7，The bracing wire 2 total length length of side being wrapped in successively on four guide wheels 9，Therefore bracing wire 2 overcomes the pulling force of extension spring 8，One end retraction being connected with extension spring 8，And this end is wrapped on thumb wheel 3，Therefore thumb wheel 3 rotates with，So shifting block 31 moves and conflicts with reflector 4，Shifting block 31 continues to move to reflector 4 and rotates along rotating shaft 41，Now photoswitch 5 is triggered，Produce a signal to control system，System can record clamping limb 7 and leave initial position，Clamping limb 7 continues to close up，Shifting block 31 continues to move to after reflector 4，Thumb wheel 3 rotates shifting block 31 and again contacts and stir reflector 4 with reflector 4，So photoswitch 5 is triggered，Again produce a signal to control system，System can record clamping limb 7 and arrive the position of clamp position，Two positions of clamping limb 7 are carried out sensing and record by a set of sensing device，After system receives the signal that clamping limb 7 is held in place，Follow-up program can start，When needs clamping limb 7 resets，Drive mechanism drives clamping limb 7 to reset，First shifting block 31 is stirred reflector 4 and is produced first signal and be transferred to control system，System can obtain clamping limb 7 and leave clip position，Shifting block 31 second time is stirred 4 second signals of reflector and is transferred to control system，System will obtain the signal that clamping limb 7 resets，Follow-up program just can operate.
