Abstract

The utility model relates to a safety apparatus for a sight-seeing lift. The top part of a well rail and the supporting frame of a pit are provided with an upper and a lower reels; one end of an upper curtain and one end of a lower curtain are fixed with the connecting rods installed on the top and the bottom parts of a cage; the other end of the upper curtain and the other end of the lower curtain are respectively fixedly coiled on the upper and the lower reels. Each of the reels is provided with a steel cable coiled on each of the curtains in reverse direction, and the end of the steel cable is provided with a heavy hammer, wherein, the steel cable on the lower reel is connected with the heavy hammer via a reversing fixed pulley installed on the supporting frame on the top part of the well rail. The utility model can effectively prevent dropping objects from being splashed out of the outer port of the well rail, having the advantages of simple structure, reasonable design, and low construction cost.

Description

Sightseeing elevator hoistway safety precaution curtain

The utility model belongs to the annex of sightseeing elevator, particularly relates to a kind of safety device of sightseeing elevator.

Because the horizontally-arranged top layer of hoistway of sightseeing elevator at building, therefore be deposited in layer door end bank and near dirt sand so that rubbish, move up and down along with cab unavoidably and start and stop outside hoistway is scattering into the building, the cleaning that is unfavorable for environment, What is more is that greasy dirt, parts etc. in machine room and the hoistway device fall and bounce-back spills, and will produce serious more adverse consequences.

The utility model aims to provide a kind of safety precaution curtain that prevents that falling object from spilling from hoistway, to reach the purpose that improves the sightseeing elevator safety.

Above-mentioned purpose obtains by the following technical programs: upper and lower spool is housed on the support of well headroom and pit, the thick stick that is connected that is fixed on cab top and bottom is fixed an end of heavy curtain up and down respectively, the other end is fixed with upper and lower spool spooling respectively, each spool is provided with the cable wire that oppositely twines with heavy curtain, there is weight in its end system, wherein the cable wire of lower winding shaft joins with weight after being installed in the fixed pulley on the well headroom support.

Be fixed with the guide rail of chain on the hoistway support of cab both sides,, captive joint equidistant fixing spring hook on the chain with the pipe link of cab top, bottom by the two ends of the ring chain of the sprocket engagement at guide rail two ends;

The heavy curtain dual-side is provided with the dog hole that engages with spring hanger, and its backplate is fixed on the chain guide.

Further specify the utility model with drawings and Examples below:

Accompanying drawing 1 the utility model structural representation

Accompanying drawing 2 Fig. 1 partial enlarged drawings

Description of drawings: pit medium-height trestle 1, lower winding shaft 2, cable wire 3, following heavy curtain 4, under connect thick stick 5, cab 6, on connect thick stick 7, weight 8, backplate 9, last heavy curtain 10, fixed pulley 11, hoistway upper bracket 12, dog hole 13, upper winding shaft 14, sprocket wheel 15, guide rail 16, spring hanger 17, chain 18, supporting plate 19, carrier bar 20.

As shown in Figure 1, heavy curtain (10) (4) is by last up and down, lower winding shaft (14) (2) be connected thick stick (7) (5) the hoistway collar extension all sealed, each heavy curtain moves up and down with cab (6), and finish corresponding spooling or unreel action, with its course of action of behavior example explanation under the cab, when cab (6) is descending, upper winding shaft (14) unreels, cable wire (3) twines on this axle thereupon, weight moves on (8), and meanwhile, following heavy curtain (4) loses pulling force, under the effect of weight (8 '), lower winding shaft (2) is rotated following heavy curtain is carried out spooling, otherwise cab is up, the rotation direction of each spool is with aforementioned opposite, and each heavy curtain still can be finished the whole sealings to the hoistway collar extension so repeatedly.For making heavy curtain smooth, and partial curling not, the chain (18) of annular movement and heavy curtain uniform movement with cab operation and in guide rail (16), spring hanger (17) is accurately engaged with dog hole (13), as shown in Figure 2, spring hanger is fixed by its supporting plate (19) and carrier bar (20) while riveted, and spring hanger is convenient to break away from chain turning and dog hole.When hook engages with dog hole, make the equilibratory pulling force in the heavy curtain left and right sides, make the smooth and partial curling not of heavy curtain, the setting of backplate (9) prevents that heavy curtain from shaking significantly, is convenient to hook, hole joint, the while cooperates with guide rail and prevents that chain from reversing.This routine heavy curtain is selected knit nylon cloth for use, and its tensile strength is big, not yielding and wearing and tearing.

The utlity model has following advantage:

1. prevent effectively that falling object from spilling from the hoistway collar extension;

2. construction cost reasonable in design simple in structure is low.
