As preferably, described telescopic moving device is arranged in the type of the falling E profile that Open Side Down, the width of described telescopic moving device is consistent with the width of guardrail anchor fitting, described guide groove is arranged on telescopic moving device three frames vertically downward, and the position that two frames up and down of described anchor fitting upper part structure overlap with three frames vertical on described telescopic moving device is provided with the bolt of long stem passed for guide groove.
As preferably, a safety switch is provided with at the frame overlapping positions of the intermediate vertical of the uppermost frame of guardrail anchor fitting and lowermost frame and described telescopic moving device, the frame of described telescopic moving device intermediate vertical is provided with one and hits plate safely, described safety is hit to contact with safety switch when the vertical edge frame of plate in the middle of the telescopic moving device moves to Upper-lower Limit position and is agreed with.
Compared with prior art, usefulness of the present utility model is: this elevator guardrail retractor device, adopt guardrail Collapsible structure, in actual installation uses, can not only ensure not have influence on elevator hoistways overhead when real-world operation, and the effect of safety precaution also can be played when needing maintenance, meet Standard, one-sided hoistway space can also be saved in addition, moreover at two end positions of elevating guardrail, two position switchs are installed, control system judges the state residing for guardrail by the state of detector switch, indirect control elevator, to ensure the safety of service personnel, single unit system structure is simple, be easy to manufacture and installation operation, cost-saving.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the utility model is further illustrated:
Fig. 1 is Facad structure schematic diagram of the present utility model;
Fig. 2 is safety switch partial enlargement structural representation of the present utility model;
In figure: 1, frame; 2, guardrail anchor fitting; 3, telescopic moving device; 4, guide groove; 5, bolt of long stem; 6, safety switch; 7, safety hits plate.
detailed description of the invention:
Below in conjunction with the drawings and the specific embodiments, the utility model is described in detail:
A kind of elevator car top Telescopic guardrail of the utility model, as Fig. 1, shown in Fig. 2, integrated guard rail device arranges and is installed on elevator cage tip position, and be made up of multiple guardrail frame 1, be fastenedly connected by bolt between described frame 1, described Telescopic guardrail comprises the guardrail anchor fitting 2 being fixedly connected on sedan-chair top and the telescopic moving device 3 be flexibly connected with guardrail anchor fitting 2, described guardrail anchor fitting 2 is in falling 7 shape settings, its underpart quadra structure is bolted to connection in Jiao Bi upper position, car side, and the frame superstructure of described guardrail anchor fitting 2 is arranged on elevator car top one lateral edges and length is consistent with elevator car top lateral edges length, in addition, described telescopic moving device 3 arranges in the type of the falling E profile that Open Side Down and its width is consistent with the width of hurdle, family anchor fitting 2, the frame that described telescopic moving device 3 is vertical is provided with guide groove 4, described guide groove 4 is arranged on telescopic moving device 3 three frames 1 vertically downward, the position that two frames 1 up and down of described three frames 1 vertically and guardrail anchor fitting 2 upper part structure overlap is provided with the bolt of long stem 5 through guide groove 4, described telescopic moving device passes through guide groove 4 at guardrail anchor fitting about 2 fore and aft motion, in actual use, when elevator is in stoppage in transit inspecting state, described telescopic moving device 3 is in extended state, when described telescopic moving device 3 moves upward to appropriate location along the guide groove 4 on its frame, the stock nut tightened on guardrail anchor fitting 2 makes described telescopic moving device 3 can be anchored on guardrail anchor fitting 2 then, play the effect of protection, when elevator is in normal operating condition, tighten bolt of long stem 5 after described telescopic moving device 3 moves downward end position and make it fixing, thus also can not have influence on the upper sheaf space of elevator hoistways.
