Description
Technical field
The utility model relates to holdout device under a kind of lift car, is mainly used in elevator lift car in maintenance process and rests on appropriate pit position.
Background technology
Elevator needs car bottom maintenance, and lift car need pause at the elevator hoistways pit, and what make lift car safety is fixed on the well pit suitable position, makes the maintainer carry out car bottom maintenance operation at the elevator hoistways pit.Prior art does not have the design of the following holdout device of elevator hoistways pit in pausing, and in the maintenance operation of lift car bottom, leans on elevator cage operation to pause to the well pit suitable position, and the maintainer carries out car bottom maintenance operation at the elevator hoistways pit; Its defective is a car pause control trouble, if car downslide out of control causes maintainer's personal safety.
The utility model content
The utility model technical matters to be solved is to overcome existing above-mentioned deficiency in the prior art, and holdout device under a kind of lift car is provided.
The utility model addresses the above problem the technical scheme that is adopted: holdout device under this lift car; It is characterized in that being provided with adapter plate, center shaft, safety switch, the positioning seat that resets, recessedly take turns, hold-down arm, cushion rubber, support positioning seat, fixed mount; Center shaft, the positioning seat that resets, support positioning seat, fixed mount are all captiveed joint with adapter plate, the recessed end that is fixed on hold-down arm of taking turns, and cushion rubber is fixed on the other end of hold-down arm; Recessedly take turns, hold-down arm is inserted in center shaft; Safety switch is fixed on the fixed mount, and safety switch cooperates with recessed the wheel, and adapter plate is fixed in the hoistway inwall.
The utility model compared with prior art has the following advantages and effect: reasonable in design, and following holdout device is fixed on the well enclosure that is higher than pit, and is designed with car sinking hold-down arm, and hold-down arm can be swung.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3 is the working state schematic representation of the utility model embodiment.
The specific embodiment
Referring to Fig. 1～Fig. 3; Holdout device is provided with adapter plate 1, center shaft 3, safety switch 4, the positioning seat 5 that resets, recessedly takes turns 6, hold-down arm 7, cushion rubber 8, supports positioning seat 11, fixed mount 12 under the utility model embodiment lift car, center shaft 3, the positioning seat 5 that resets, support positioning seat 11, fixed mount 12 is fixing with adapter plate 1 welding; Recessed take turns 6 be weldingly fixed on hold-down arm 7 an end, cushion rubber 8 is fixed by bolts to the other end of hold-down arm 7; Recessed take turns 6 with hold-down arm 7 be inserted in center shaft 3 usefulness nuts 9 tighten fixing, recessed take turns 6 and hold-down arm 7 can rotate; Safety switch 4 usefulness screws 13 are fixed on the fixed mount 12, and safety switch 4 was taken turns for 6 identical connections with recessed just; Adapter plate 1 usefulness expansion bolt 2 is fixed in the hoistway inwall 10.
The technical design of the utility model embodiment hold-down arm 7 can be rotated, and pulling hold-down arm 7 struts the location in elevator hoistways, and lift car reaches holdout device down at the well pit position, carry out the maintenance of lift car bottom; Promote hold-down arm 7, hold-down arm 7 resets in hoistway inwall 10, and elevator normally moves.Technology innovation has been realized the lift car bottom in maintenance, reaches at the well pit position to stop the location down.
The utility model embodiment is recessed to take turns 6 and compresses mutually to coincide with safety switch 4 and is connected, takes turns 6 and rotates synchronously in that pulling hold-down arm 7 is recessed, and safety switch 4 is taken turns slip on 6 recessed.Supporting location on the positioning seat 11 when hold-down arm 7 struts, safety switch 4 snaps in recessed 6 the recess of taking turns just, and safety switch 4 elevator that quits work is out of service; When hold-down arm 7 resets to hoistway inwall 10, location on the positioning seat 5 that resets, recessed 6 the outstanding position of taking turns is identical with safety switch 4, safety switch 4 energising that resets, elevator normally moves.The innovation of technology makes maintainer's safety in repair the car bottom of well pit.
The technical design of the utility model embodiment cushion rubber 8 is fixed on the hold-down arm 7, and car reaches buffering when coincideing with hold-down arm 7 in the well pit position glides, can arbitrarily not damage hold-down arm 7, prolongs the service life of holdout device under the elevator.
Working process:
Pulling hold-down arm 7 is recessedly taken turns 6 and is rotated simultaneously with hold-down arm 7, and hold-down arm 7 struts in elevator hoistways; Safety switch 4 snaps in recessed 6 the recess of taking turns just; Safety switch 4 service lifts are out of service, and hold-down arm 7 is located in hoistway under the effect of supporting positioning seat 11, and lift car 15 reaches at the well pit position and stops the location down; On hold-down arm 7, reach buffering (Fig. 3) at lift car 15 under the effect of cushion rubber 8, maintenance lift car 15 bottoms; Promote hold-down arm 7; Recessedly take turns 6 and rotate simultaneously with hold-down arm 7; Hold-down arm 7 resets in the hoistway inwall 10; Recessed 6 the outstanding position of taking turns snaps in safety switch 4 and makes safety switch 4 energising that resets, and hold-down arm 7 is located 10 (off working states) in the hoistway inwall under the effect of the positioning seat 5 that resets, and elevator normally moves.
The simple deformation or the combination of every the utility model embodiment technical scheme and technical characterictic all should be thought the protection domain that falls into the utility model.
