Abstract
The utility model relates to an elevator cable pulley protector, comprising a base fixed to a cage and provided with a vertical sleeve, a pull rod sleeved into the vertical sleeve, a pressing piece fixed to the upper part of the pull rod and provided with a peripheral size greater than the inner diameter of the vertical inner sleeve, a returning elastic element located between the base and the pull rod and capable of causing the pull rod to keep an upward movement trend, a cable clamping and fixing assembly fixed to the lower part of the pull rod and a limiting switch fixed to the base, wherein the limiting switch is connected in series with an elevator safety circuit; the trigger rod of the limiting switch is in contact fit with the pressing piece; and the trigger rod of the limiting switch controls the on-off stroke of the switch to be located within the motion stroke of the pressing piece. The utility model aims to provide an elevator cable pulley protector capable of effectively protecting the cable pulley.
Description
Technical field
The utility model relates to a kind of elevator cable coaster fender guard.
Background technology
The retinue cable trunk of building hoist has multiple retinue processing mode; It is the cable coaster formula that places terraced cage below and go up and down on standard knot with terraced cage that a kind of mode is wherein arranged; Adopt this mode that a lot of advantages is arranged; But also exist a very big defective: cable coaster reason owing to certain in the process that descends with terraced cage has been stuck on the standard knot, and the operator in terraced cage and ignorant, terraced cage continues to descend; Result's ladder cage is pressed on the cable coaster and damages the retinue cable trunk, just stops until leakage tripping ladder cage.And impaired cable trunk also may be intertwined with the retinue cable trunk of another side ladder cage, causes both sides ladder cage all can not use.Such situation occurs, cable coaster is repaired difficulty, and cable bad is serious, and maintenance difficulty is high, and elevator ladder down time is long, the normal construction in building site has been caused have a strong impact on.
Summary of the invention
The purpose of the utility model is to provide a kind of elevator cable coaster fender guard that can effectively protect cable coaster.
The purpose of the utility model realizes through following technical scheme: a kind of elevator cable coaster fender guard is characterized in that: it comprises the pedestal that is fixed on the terraced cage and has vertical sleeve, be set in pull bar in the vertical sleeve, be fixed in pull bar top and the peripheral dimension compressing tablet bigger than vertical sleeve diameter, between pedestal and pull bar and can make pull bar keep up movement tendency return elastic component, the hawser that is fixed in the pull bar bottom grip assembly and be fixed in the limit switch on the pedestal; Said limit switch is connected with the elevator vital circuit, the touch pole of limit switch and compressing tablet contact matching, and the stroke that the touch pole master cock of limit switch opens and closes is positioned at the movement travel of compressing tablet.
The principle of work of the utility model is following:
Captive joint with terraced cage through elevator cable coaster fender guard with the hawser that keeps the cable coaster stress balance being located at retinue cable trunk respective side.When cable coaster normally moves, cable stress, the pulling pull bar overcomes return elastic component pressure, and the pulling pull bar drives compressing tablet, makes compressing tablet push down the touch pole of limit switch, and limit switch remains on closure state, is communicated with the vital circuit of elevator, and elevator normally moves; When cable coaster blocked, descending if elevator continues, cable stress diminished; The return elastic component overcomes the hawser pull that receives, and drives the pull bar upward movement, and the compressing tablet on the pull bar fails to push down the touch pole of limit switch; The limit switch action; Limit switch breaks off, and the safety return circuit of elevator breaks off, and the elevator operation stops.
Compared to prior art, the advantage of the utility model is: it is not only simple in structure, and it is convenient to install, and can effectively protect cable coaster, guarantees the normal operation of elevator, ensures construction speed.

The specific embodiment
Below in conjunction with Figure of description and embodiment the utility model content is elaborated:
Like the embodiment scheme drawing of Fig. 1 to a kind of elevator cable coaster fender guard that provides for the utility model shown in Figure 8.
A kind of elevator cable coaster fender guard is characterized in that: it comprises the pedestal 2 that is fixed on the terraced cage 1 and has vertical sleeve 2-1, be set in pull bar 3 in the vertical sleeve 2-1, be fixed in pull bar 3 tops and the peripheral dimension compressing tablet 4 bigger than vertical sleeve 2-1 internal diameter, between pedestal 2 and pull bar 3 and can make pull bar 3 keep up movement tendency return elastic component 5, the hawser that is fixed in pull bar 3 bottoms grip assembly and be fixed in the limit switch 6 on the pedestal 2; Said limit switch 6 is connected with the elevator vital circuit, the touch pole 6-1 of limit switch 6 and compressing tablet 4 contact matching, and the stroke that the touch pole 6-1 master cock of limit switch 6 opens and closes is positioned at the movement travel of compressing tablet 4.
Said hawser grips assembly and comprises the adapter plate 7 that is fixedly arranged on the pull bar 3, is posted by the clamping piece 8 of adapter plate 7 one sides and is used for making adapter plate 7 and clamping piece 8 cooperates the clamping locking piece 10 that clamps hawsers 9; Said clamping piece 8 is provided with hawser positioning clamping groove 10-1 near adapter plate 7 one sides.
Perpendicular orienting sleeve 7-1 or the pilot bar of being provided with on the said adapter plate 7, the bottom of said pedestal 2 is provided with pilot bar 2-2 or the orienting sleeve that cooperates guiding with orienting sleeve 7-1 or pilot bar.
