Detailed description of the invention
All features disclosed in this specification sheets, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Arbitrary feature disclosed in this specification sheets (comprising any accessory claim, summary and accompanying drawing), unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object.That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in detail.
As depicted in figs. 1 and 2, according to an embodiment of the present utility model, the present embodiment discloses a kind of building hoist safety anti-falling device, it comprises base 21, proof safety protective device 22 and winch 23, base is fixed on ground pedestal 24, base is provided with winch, winch is wound with steel rope; Proof safety protective device is arranged on base, and steel rope one end, around on described winch, is connected with proof safety protective device after other end pile warp pulley; Concrete, steel rope one ends wound is on the reel of winch, the back timber pulley being positioned at pulley on the crossbeam of building hoist top and cage is walked around in one end, be connected on the pull bar of three anti-devices, along with the winding of steel rope on winch and release, thus cage is driven to do upper and lower perpendicular movement along track.When cage carry material rise to predetermined stop time, open the portable plate of cage bearing support, cage is just reliably supported on bearing support, even if now steel rope burst slack rope or fracture, cage also can be safe and sound.When cage is on ground, activity safety door is opened automatically, is convenient to load.When ground is left in cage rising, activity safety door is closed automatically, in case material drops.When cage is in predetermined stop, upset safety door can be opened, so that discharging.If material is overweight when promoting, three anti-devices will automatic cut-off power, and winch cannot be worked.If cage is increased beyond predetermined altitude, then anti-overheight attachment can pull the case lid of three anti-devices by steel rope, thus disconnects riser circuit circuit, makes cage do descending motion.If cage happens suddenly after leaving ground, slack rope or disconnected rope, then brake falling protector action, can reliably by cage clamping in orbit, and meanwhile, three anti-device power-off, winch is shut down, and can resume work after trouble-shooting.
Preferably, the present embodiment optimizes braking falling protector further, braking falling protector comprises gear, centrifugal speed-limit device and cone drum brake, centrifugal speed-limit device 7 is formed primarily of centrifugal seat and centrifugal-block, centrifugal-block is fixed by the pull bar and centrifugal seat being provided with stage clip above, and the end of centrifugal-block is provided with spring leaf and pressing plate.
Bore drum brake by shell 1, cone 6, disk spring 9, hold-down nut 10, hinder 13 formations of turn-taking, be provided with friction ring 5 between shell 1 and cone 6, friction ring 5 is fixed on the inwall of shell 1; The front end of cone drum brake is provided with large end cap 2, and rear end is provided with bonnet 11, is fixedly connected with respectively with shell 1; Shell 1 is provided with cover cap 12 near the downside of bonnet end.Large end cap 2 is provided with the ball bearing of main shaft 3 of two sealings, and centrifugal speed-limit device 7 is arranged in cone 6, and the rotating shaft of stem gear 4 is connected with centrifugal speed-limit device 7 by the ball bearing of main shaft 3 of two band sealings; The other end of centrifugal speed-limit device 7 rotating shaft is fixed in the cone end of cone 6 by bearing 8; In the present embodiment, stem gear 4 directly engages with guide rail bracket tooth bar, and the teeth number of stem gear 4 is less than 15, and stem gear 4 can accomplish that profile deadweight is lighter and handier compared to existing technology, reduces the unbalanced moment of rotatable parts, improves running stability.
When proof safety protective device is ineffective, when the cage of building hoist falls because of fault, the centrifugal-block of braking falling protector is by the increase along with weight gliding acceleration, and the centnifugal force making it produce also increases gradually.When the speed that weight glides reaches certain value, centrifugal-block completes expansion action under the influence of centrifugal force, head in the uniform wherein groove of cone 6 inner chamber, cone 6 is produced rotate, on centrum 6, screw thread constantly screws in hold-down nut 10, and the displacement of hold-down nut 10 on centrum 6 screw thread, produces pressure to disk spring 9, on disk spring 9, antagonistic force makes the conical surface of centrum 6 produce in friction process at the friction ring 5 with shell 1 constantly to increase pressure, thus plays brake action.
The present embodiment, by multiple anti-falling protection, guarantees the construction safety of building hoist.
Spoken of in this manual " embodiment ", " another embodiment ", " embodiment ", etc., refer to the specific features, structure or the feature that describe in conjunction with this embodiment and be included at least one embodiment of the application's generality description.Multiple place occurs that statement of the same race is not necessarily refer to same embodiment in the description.Furthermore, when describing specific features, structure or a feature in conjunction with any one embodiment, what advocate is also drop in scope of the present utility model to realize this feature, structure or feature in conjunction with other embodiments.
Although the multiple explanatory embodiment here with reference to utility model is described the utility model, but, should be appreciated that, those skilled in the art can design a lot of other amendment and embodiment, these amendments and embodiment will drop within spirit disclosed in the present application and spirit.More particularly, in the scope of, accompanying drawing open in the application and claim, multiple modification and improvement can be carried out to the constituent elements of subject combination layout and/or layout.Except the modification of carrying out constituent elements and/or layout is with except improvement, to those skilled in the art, other purposes also will be obvious.
