Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the overhauling elevator safety pin mechanism that the specific embodiment of the invention provides.A kind of overhauling elevator safety pin mechanism, comprise safety pin 1, safety pin adapter plate 2, safety pin plate 3 and UKS switch 4, wherein safety pin adapter plate 2 is fixed on car upper beam 5, safety pin 1 runs through safety pin adapter plate 2 and is inserted in the hole 7 on the safety pin plate 3 that is fixed on car guide rail 6, UKS switch 4 is fixed on safety pin adapter plate 2, and safety pin 1 is provided with eccentric stiffener, and eccentric stiffener matches with UKS switch 4, when safety pin 1 rotates, eccentric stiffener can open described UKS switch.
Eccentric stiffener on safety pin 1 is eccentric shaft 8 or cam, and when described eccentric shaft 8 or cam forward the position that can touch UKS switch 4 to, UKS switch 4 action, is broken as elevator and runs the circuit providing power.By the running state of electrical control elevator, for maintenance elevator adds safety control.
The above-mentioned UKS of mentioning switch 4 is fixed on safety pin adapter plate 2, can adopt various detachable and non-dismountable connection mode, select bolt to connect, can dismantle in present embodiment, be convenient to maintenance and the replacing of UKS switch 4.
For the ease of rotation and the axial motion of safety pin 1, on safety pin 1, vertical safety pin axis direction is installed with handle bar 9, handle bar 9 one end is provided with screw thread or is fixed with bolt, the relevant position of safety pin 1 is provided with the tapped bore matched with handle bar 9, and handle bar 9 is screwed into tapped bore and reaches the object be connected with safety pin 1.
Arbitrarily rotate for preventing safety pin 1 or move vertically, the breach 10 placing handle bar 9 is provided with in the edge of safety pin adapter plate 2, when not use safety pin 1, handle bar 9 is put into breach 10, limit the axial motion of safety pin 1, in addition because the friction force between handle bar 9 and breach 10 surface limits the rotation of safety pin 1.Breach 10 is at least two, and along the arrangement of safety pin axis direction, after moving axially safety pin 1, is fixed the position of safety pin 1 by the another one breach 10 handle bar 9 being put into axial arranging.
Safety pin plate 3 is fixed on car guide rail 6 by guide rail pressure guide plate 11, and the number in the hole 7 on safety pin plate 3 is at least one, and when the number in hole 7 is two or more, safety pin 1 can adjust locked position among a small circle.
Safety pin adapter plate 2 is connected with car upper beam by bolt, rivet or welding.
When using safety pin mechanism provided by the invention to overhaul, first the handle bar 9 shown in Fig. 1 is taken out from described breach 10, meanwhile spin safe pin 1, after safety pin 1 eccentric shaft 8 or cam rotate to an angle, eccentric shaft 8 touches UKS switch 4, UKS switch 4 action thus, is disconnected as elevator motion provides the circuit of power supply; Then by driving handle bar 9, safety pin 1 is inserted in the hole 7 of safety pin plate 3; Finally handle bar 9 is pressed into along in axial another breach 10 arranged of safety pin on safety pin adapter plate 2, beginning upkeep operation.After service work terminates, resetted by safety pin 1 by handle bar 9, then manually to be resetted by UKS switch 4, be communicated with for elevator motion provides the circuit of power supply, elevator can normally use.
