Wherein: 1. a car; 2. a lower guardrail; 3. an upper guardrail; 4. a through hole; 5. erecting a rod; 6. a limiting hole; 7. a spacing pin; 8. a safety switch; 9. a support bar; 10. a lower cross bar; 11. an upper cross bar; 12. a screw hole; 13. hanging a ring; 14. and a chain.
Detailed Description
The invention will be further described with reference to the following drawings and examples:
the first embodiment is as follows: referring to fig. 1, the car top guardrail structure comprises a car 1, wherein guardrails are arranged at the top of the car and comprise a lower guardrail 2 and an upper guardrail 3, the bottom of the lower guardrail is vertically arranged at the top of the car, a plurality of groups of through holes 4 are arranged on the top surface of the lower guardrail at intervals, a plurality of groups of vertical rods 5 are arranged at the bottom of the upper guardrail, and the bottom of each group of vertical rods is respectively inserted into one group of through holes; a plurality of limiting holes 6 are formed in at least two groups of upright rods and are arranged at intervals from top to bottom; at least two groups of limiting pins 7 are placed on the lower guardrail, one end of each group of limiting pins is inserted into the limiting holes of the corresponding vertical rods in the pull-up state of the lower guardrail, and the outer edge surface of the bottom of the other end of each limiting pin is abutted against the top surface of the lower guardrail;
and a safety switch 8 is arranged above the lower guardrail, and the upper part of the upper guardrail is contacted with the safety switch under the descending state of the upper guardrail.
In this embodiment the safety switch is in electrically controlled connection with the controller of the elevator. When the safety switch is triggered, the elevator can run normally, and the elevator can reach a preset position by moving upwards and is relatively close to the top of the elevator shaft. If the safety switch is switched off, the elevator can only move a certain distance when moving upwards, and the distance from the top of the elevator shaft is larger, so that an operator can be provided with a standing space. When the elevator runs, the lower guardrail descends, so that the upper part of the upper guardrail is in contact with the safety switch, the elevator can run normally, and the space at the top of the elevator shaft occupies a small space. If it needs to glue at the car top and overhauls to say operating personnel, operating personnel glues behind the car top, pulls out upper portion guardrail for the pole setting rebound, upper portion guardrail and safety switch's contact separation, just can't continue to rise after going to certain position upwards like this, the operating personnel of being convenient for overhauls like this. After the upper portion guardrail is pulled up, insert the spacing downthehole that corresponds with the spacer pin, the upper portion guardrail receives heavy automatic decline like this, also can be blockked by the spacer pin, plays limiting displacement. Therefore, the upper guardrail and the lower guardrail play a role in protection, so that the operator is prevented from falling from the top of the car, and the safety of the operator in maintenance is ensured.
Referring to fig. 1, the lower guardrail includes a plurality of support rods 9 and a plurality of lower cross rods 10, the support rods are arranged at intervals, the bottoms of the support rods are vertically arranged at the top of the car, the lower cross rods are parallel to the top of the car, two ends of each lower cross rod are connected with two adjacent sets of side walls of the support rods, and the top surfaces of the lower cross rods are flush with the top surfaces of the support rods.
The upper guardrail includes upper portion horizontal pole 11 and multiunit pole setting 5, the upper portion horizontal pole is on a parallel with the lower part horizontal pole sets up, the pole setting perpendicular to the upper portion horizontal pole sets up, the multiunit the top of pole setting install perpendicularly in on the bottom surface of upper portion horizontal pole, and the multiunit the pole setting interval set up in on the bottom surface of upper portion horizontal pole.
Each group of through holes are arranged on the top surface corresponding to the support rod, and the bottom of the vertical rod is inserted into the corresponding through hole.
The safety switch is arranged on the side wall of the group of the lower cross rods, and the bottom surface of the upper cross rod is in contact with the safety switch when the upper guardrail descends.
In this embodiment, under normal conditions, the pole setting receives the weight of self gravity and upper portion horizontal pole can automatic downstream for upper portion horizontal pole and safety switch contact, the height ratio of guardrail is than lower like this, and the height that elevator car rises is higher, and is closer to the top of elevator well, reduces the occupation of elevator well space. When needs overhaul, operating personnel upwards pulls out the pole setting from the through-hole for upper portion horizontal pole rebound, and it is downthehole to recycle the spacer pin and insert spacing, and the opposite pole is spacing downwards, can promote the height of guardrail like this, plays protection maintainer's effect, and the upper portion horizontal pole can break away from safety switch in addition, makes elevator car can not appear the problem of dashing the top, plays the duplicate protection effect.
Referring to fig. 1, a plurality of screw holes 12 are formed in the lower cross rod, at least two screw holes are respectively screwed with a hanging ring 13, and each group of limiting pins is connected with a group of hanging rings in a hanging manner through a chain 14.
When the upper guardrail descends, the end part of the limiting pin is separated from the limiting hole; and under the condition that the upper guardrail is pulled upwards, the end part of the limiting pin is inserted into the corresponding limiting hole.
In this embodiment, in order to prevent losing of spacer pin, articulate on the link through the chain, when not using, the spacer pin is spacing by the chain, the problem of losing can not appear, when using, insert the spacer pin corresponding spacing downthehole can, when dismantling the spacer pin moreover, it can to grasp the chain with the spacer pin follow spacing downthehole pull-out, also be convenient for the dismantlement of spacer pin.
