Abstract
The open a kind of Pawl protection device of the present invention; device is triggered including tooth bar, ratchet and connecting rod; described tooth bar is arranged on lift lower mast standard knot; it is respectively articulated with ratchet on the cage of described tooth bar both sides and connecting rod triggers device; described ratchet matches with tooth bar; described connecting rod triggers device and connects load-bearing wires rope, described cage is provided with the first extension spring and is connected with ratchet, described cage is provided with the second extension spring and is connected with connecting rod triggering device；This apparatus structure is simple, when lift generation accidental falling, first trigger Pawl protection device, directly withstood shocks load by Pawl protection device, thus ensures the normal work of catching device, makes lift use safer, reduces the generation of security incident.
Description
Technical field
The present invention relates to elevator safety protector, particularly relate to a kind of Pawl protection device.
Background technology
Lift plays an important role in terms of carrying out vertical transport personnel and goods in producing, living,
Its security reliability is increasingly taken seriously.The great thing of the crane gear such as crane, electric block
Therefore often malfunctioning because of lifting machine off-axis, service brake, the gear tooth breakage of decelerator or middle connect
Part gets loose etc. the weight hypervelocity tenesmus caused, and causes the major accident of equipment personal injury.
The commonly used safety guard of current domestic lift mostly is single catching device, has certain
Potential safety hazard, when lift generation accidental falling, the enormous impact load produced due to moment, can
The gear of catching device end can be destroyed, cause catching device to lose efficacy and injures and deaths of falling.
Summary of the invention
Present invention solves the technical problem that and be: this device is intended installing a set of Pawl protection device on cage,
When lift generation accidental falling, the action of Pawl protection device elder generation, the enormous impact that moment is produced
Load turns is born by ratchet, it is ensured that catching device end gear stress is little, though ratchet fracture, the most not
Catching device can be affected normally work.
For reaching this purpose, the present invention by the following technical solutions:
A kind of Pawl protection device, triggers device including tooth bar, ratchet and connecting rod, and described tooth bar is arranged
On lift lower mast standard knot, the cage of described tooth bar both sides is respectively articulated with ratchet and connecting rod triggers
Device, described ratchet matches with tooth bar, and described connecting rod triggers device and connects load-bearing wires rope, described
It is provided with the first extension spring on cage to be connected with ratchet, described cage is provided with the second extension spring and touches with connecting rod
Transmitting apparatus connects.
Further, described connecting rod triggers device and is connected load-bearing wires rope on the jointed shaft of cage.
Preferably, described first extension spring, the second extension spring all use spring wire to be material.
Further, described connecting rod triggers device and includes mounting rod and frizzen, and described connecting rod triggers dress
Putting and be hinged on cage by mounting rod one end, what described frizzen was vertical with mounting rod is arranged on installation
In the middle part of bar and towards ratchet, it is integral type structure that described connecting rod triggers device.
The invention have the benefit that simple in construction, when lift generation accidental falling, the most tactile
Sending out Pawl protection device, directly withstood shocks load by Pawl protection device, thus ensures catching device
Normal work, makes lift use safer, reduces the generation of security incident.
Accompanying drawing explanation
Below according to drawings and Examples, the present invention is described in further detail.
Fig. 1 is Pawl protection device structural representation of the present invention.
In figure:
1, tooth bar；2, ratchet；3, connecting rod triggers device；4, load-bearing wires rope；5, the first extension spring；
6, the second extension spring；7, mounting rod；8, frizzen.
Detailed description of the invention
Further illustrate technical scheme below in conjunction with the accompanying drawings and by detailed description of the invention.
As it is shown in figure 1, in the present embodiment, a kind of Pawl protection device of the present invention, including
Tooth bar 1, ratchet 2 and connecting rod trigger device 3, and described tooth bar 1 is arranged on lift lower mast standard knot,
Described lift lower mast standard knot is hung oneself and is provided with cage, and the cage of described tooth bar 1 both sides is respectively provided with
Having ratchet 2 and connecting rod to trigger device 3, described ratchet 2 is arranged on described tooth bar 1 active side of tooth,
Matching with described tooth bar 1, described ratchet 2 is hinged on cage, arranged by its working end
One extension spring 5 pulls it toward tooth bar；
Described connecting rod triggers device 3 and includes mounting rod 7 and frizzen 8, described mounting rod 7 and triggering
Bar 8 is structure as a whole, and described connecting rod is triggered device 3 and is hinged on cage by mounting rod 7, and leads to
Cross described jointed shaft and connect load-bearing wires rope 4, in the middle part of described mounting rod 7, be provided with frizzen 8, described
Frizzen 8 is perpendicular to described mounting rod 7, and described frizzen 8 end withstands on ratchet 2, described peace
Dress bar 7 is also connected with the second extension spring 6 being fixed on cage, and connecting rod is triggered by described second extension spring 6
Device 3 is pulled away from ratchet 2.
Described first extension spring the 5, second extension spring 6 all uses spring wire to be material.
Device is triggered owing to load-bearing wires rope 4 is in its tension linkage of tight state during normal operating conditions
3 make it keep state in Fig. 1, and now frizzen 8 holds out against ratchet 2 and makes the ratchet 2 can not be with tooth bar 1
Contact；When occurring unexpected load-bearing wires rope 4 to be in relaxation state, cage falls uncontrolled,
Now the effect lower link triggering device 3 in the second extension spring 6 rotates around jointed shaft, makes frizzen 8 remote
From ratchet 2, ratchet 2 rotates to tooth bar 1 under the effect of the first extension spring 5, finally its working end card
Enter in rack tooth, alleviate the impulsive force that cage hypervelocity whereabouts produces.
It is to be understood that, above-mentioned detailed description of the invention is only presently preferred embodiments of the present invention and used skill
Art principle, in technical scope disclosed in this invention, any those familiar with the art is held
The change being readily conceivable that or replacement, all should contain within the scope of the present invention.
