In order to realize object above, this utility model adopts the following technical scheme that a kind of counterweight fag end device, including counterweight fag end beam, slide on counterweight fag end beam and be equipped with counterweight hitch rod, counterweight hitch rod stretches out the upper part of counterweight fag end beam and is arranged with stage clip, the upper end of stage clip and the locating part top press-fit on counterweight hitch rod, counterweight hitch rod stretches out and is fixed with steel wire rope in the part of counterweight fag end beam bottom, it is fixedly installed contact switch in the side of counterweight hitch rod on described counterweight fag end beam, the contact of contact switch is downward, be fixed on counterweight hitch rod counterweight hitch rod under the effect of stage clip on move after hit plate with the switch of contact.
Described switch hits plate and is in the top of stage clip.
Described locating part is two nuts that fixing rotation is located on counterweight hitch rod.
Described switch is hit plate and is set on counterweight hitch rod by through hole on it, and switch hits plate and is fixed between described two nut.
Described contact switch is fixed on counterweight fag end beam by switch mounting bracket and base plate, and contact switch is fixed in switch mounting bracket, and switch mounting bracket is fixed on base, and base is fixed on counterweight fag end beam.
It is fixed with in described switch mounting bracket to stretch to and switchs the contact protection projection hitting plate.
Described switch mounting bracket is L shaped plate, base plate is also L-shaped, the part of base plate bending side is fixed and is sticked on the upper surface of counterweight fag end beam, the part of switch mounting bracket bending side is fixed in the part of base plate bending opposite side, contact switch is securely fitted in switch mounting bracket, and the part of switch mounting bracket bending opposite side stretches to counterweight hitch rod.
Described switch mounting bracket and base are by the fixing assembling of bolt assembly and vertical slotted hole.
Described contact protection projection is fixed in switch mounting bracket.
Described described contact protection projection is jackscrew, and the rotation of jackscrew screw thread is located in switch mounting bracket.
Counterweight hitch rod side of the present utility model is provided with contact switch, being provided with switch on counterweight hitch rod and hit plate, after Elevator weight sensor squats the end, steel wire rope acts on the lower pulling force on counterweight hitch rod and disappears, under the effect of stage clip, move on counterweight hitch rod, hit the contact of plate contact contact switch, contact switch action, can accurately judge the moment at the bottom of the crouching of counterweight, by in contact switch traction machine circuit, traction machine can be controlled and stop operating so that elevator device meets Standard.
Being fixed with in switch mounting bracket of the present utility model to stretch to and switch the contact protection projection hitting plate, the existence of contact protection projection is possible to prevent the contact of contact switch to be damaged by excessive compression.
Switch mounting bracket of the present utility model and base are by the fixing assembling of bolt assembly and vertical slotted hole, in that context it may be convenient to regulation is fixed on the position of the contact switch in switch mounting bracket, and makes contact switch and switch hit the position relationship between plate.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of this utility model embodiment；
Fig. 2 is that the contact switch in Fig. 1 hits plate and the installation diagram of contact protection projection with switch.
Detailed description of the invention
nullA kind of embodiment of counterweight fag end device，In fig. 1 and 2，Installing hole is offered on its counterweight fag end beam 1，Slide in installing hole and be equipped with counterweight hitch rod 2，The number of counterweight hitch rod 2 is corresponding with the radical of steel wire rope，Counterweight hitch rod 2 stretches out and is arranged with stage clip 3 in the upper part of counterweight fag end beam 1，Counterweight hitch rod 1 is fixedly arranged above two nuts 4 in stage clip 3，It is provided with switch between two nuts 4 and hits plate 5，Switch hits one end of plate 5 and offers installing hole，Switch is hit plate 5 and is set on counterweight hitch rod 2 by installing hole thereon，Switch hits plate 5 compression and is arranged between two nuts 4，The top, upper end of stage clip 3 is pressed on nut 4 at the bottom，The top, lower end of stage clip 3 is pressed on counterweight fag end beam，The lower end of counterweight hitch rod 2 is fixed with steel wire rope，It is fixedly installed contact switch 6 in the side of counterweight hitch rod 2 on counterweight fag end beam 1，The contact of contact switch 6 is downward，Contact switch 6 is fixed on counterweight fag end beam 1 by switch mounting bracket 8 and base plate 9，Switch mounting bracket 8 is L shaped plate，Base plate 9 is also L-shaped，Base plate 9 bends the part of side and fixes and be sticked on the upper surface of counterweight fag end beam 1，Switch mounting bracket 8 bends the part of side and is fixed on base plate 9 and bends in the part of opposite side，Contact switch 6 is securely fitted in switch mounting bracket 8，Switch mounting bracket 8 bends the part of opposite side and stretches to counterweight hitch rod 2.The contact of contact switch 6 hits plate 5 towards switch, after counterweight is pressed on buffer, adds pulling force hour on a steel cord, under the effect of stage clip, counterweight hitch rod moves, and switch hits plate 5 and touches the contact of contact switch 6.Vertical slotted hole is offered in the part of the bending side of switch mounting bracket 8, base 9 bends the vertical slotted hole that the slotted hole offered in the part of opposite side and switch mounting bracket 8 coordinates, and bolt assembly is through switch together with switch mounting bracket 8 and base 9 be securely fitted in by mounting bracket 8 with the slotted hole of base 9.Being provided with in the part of contact switch 6 in switch mounting bracket 8 and be installed with jackscrew 7, jackscrew 7 stretches to switch and hits plate, hits the upper pan position of plate 5 for limit switch, and protection contact switch 6 is not damaged.
