The utility model content
Technical problem to be solved in the utility model is to provide a kind of elevator cage top overhauling safety device, and this device can be protected the injury that is not subjected to elevator under the abnomal condition the staff of car top layer maintenance.
For solving the problems of the technologies described above the technical solution of the utility model: elevator cage top overhauling safety device.Comprise middle level guardrail, active side guardrail and movable back guardrail, the middle level guardrail is fixed on the car upper beam of elevator, and active side guardrail and movable back guardrail are movably connected on the guardrail of middle level by regulating bolt.
In the above-mentioned elevator cage top overhauling safety device, active side guardrail and movable back guardrail are the both sides up and down that are connected to the middle level guardrail.
Beneficial effect: compared with prior art, the staff that the utility model can be protected in the car top maintenance effectively guarantees the safety of service personnel not by the up elevator injury of abnomal condition, reduces the generation of injury accident.This device is widely used in common passenger lift and inorganic tenant's ladder.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a mounting structure scheme drawing of the present utility model.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
The specific embodiment
Embodiment.As shown in Figure 1, 2, comprise middle level guardrail 1, active side guardrail 2 and movable back guardrail 3, guardrail 1 usefulness screw bolt and nut in middle level is fixed on the car upper beam 4 of elevator, active side guardrail 2 is by regulating the upside that bolt 5 is movably connected in middle level guardrail 1, and movable back guardrail 3 is by being movably connected in the downside of middle level guardrail 1 by adjusting bolt 5.
When elevator normally moved, active side guardrail 2 of this device and movable back guardrail 3 were in contraction state (shown in the dotted portion of Fig. 1).When service personnel enters car top and carries out upkeep operation, can unscrew and regulate bolt 5, as required active side guardrail 2 and movable back guardrail 3 are upwards promoted (shown in the solid line part of Fig. 1) to correct position, tighten then and regulate bolt 5, thus the service work personnel's that guarantee at car top safety.The local 750mm that active side guardrail 2 of this device and movable back guardrail 3 can be stood from protective position apart from the maintainer rises to the 1100mm place always.
Embodiment of the present utility model is not limited to the foregoing description, all belongs within the protection domain of the present utility model in the various variations of making under the prerequisite that does not break away from the utility model aim.
