Description
Technical field
The utility model relates to a kind of organic machine room-free elevator velocity limiter, belongs to elevator up-down overspeed protection safety component class.
Background technology
At present, organic machine room-free elevator is generally the centrifugal hammer that gets rid of with the biswitch velocity limiter, and it is made of rope sheave, support or frame, ratchet and pawl arrangement, rod assembly, centrifugal independent rack that gets rid of hammer, two electric switches and be used to install switch etc. usually.The major defect that this biswitch velocity limiter exists is: 1, two electric switches is arranged apart, and one is contained on the support side, and another is contained on the independent support.Because a switch need be contained on the independent support, make the overall height of velocity limiter too high, and because rocking of support can cause switch slippage downwards, cause the velocity limiter misoperation and cause elevator accident to take place.2, because of there not being to be provided with the manual triggers mechanism (eccentric wheel assembly) that can make velocity limiter generation mechanical action, when normal operation of elevator or overspeed, velocity limiter can not have artificial mechanical action, and therefore relevant elevator detects test also can't carry out or can't successfully carry out.
Chinese patent by retrieval, the invention of relevant velocity limiter aspect has much, as China Patent No.: 03255860.0, its electric switch is installed on the frame, and does not have manual triggers mechanism (eccentric wheel assembly).China Patent No.: 200520100885.9,200410053058.9,03230308.4, these patents all do not relate to technology contents provided by the utility model.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming that above-mentioned existing biswitch velocity limiter exists, a kind of organic machine room-free elevator velocity limiter is provided, make velocity limiter can not produce misoperation by the installation site that changes electric switch and cause that accident takes place, by being set, eccentric mechanism realizes the artificial power operation of manual triggers, to make things convenient for the detection test of elevator.
The technical scheme of Cai Yonging is for achieving the above object: the utility model provides a kind of organic machine room-free elevator velocity limiter, comprise the general parts of velocity limiter, it is characterized in that: velocity limiter two electric switches---safety return circuit switch and trigger switch are the same side that is arranged in the support side plate up and down, wherein: the safety return circuit switch is fixed installation, but the trigger switch parallel motion is by its position of parallel motion adjustment; Described velocity limiter also comprises an eccentric mechanism and pull bar, and eccentric mechanism is arranged on the same support side plate of electric switch; On the rope sheave web of described velocity limiter trip(ping) bar is housed.
The utility model compared with prior art has following good effect:
1, the utility model is owing to be installed in two electric switches the same side of support side plate, so do not need the former switch bracket that is provided with separately, this layout reduces the whole height of velocity limiter greatly, and has avoided effectively causing the defective that elevator accident takes place because of switch glides.
Again since be arranged in following trigger switch can parallel motion, help adjusting its position.
2, owing to increase by an eccentric wheel assembly, be connected on the machine seat board by eccentric key, with switch the same side, eccentric wheel can rotate around pin, by fixing the extension spring holding position.During the velocity limiter running, the hand rotation eccentric wheel makes it touch mutually with the afterbody of trip(ping) bar, just can make the velocity limiter people for carrying out mechanical action.
The utility model is particularly useful for organic machine room-free elevator velocity limiter, has rationally distributed, compact conformation, safe and reliable, is a kind of desirable organic machine room-free elevator velocity limiter.

The specific embodiment
Further describe the utility model technology contents and embodiment below in conjunction with accompanying drawing.
Organic machine room-free elevator velocity limiter that the utility model provides, comprise the general parts of velocity limiter, parts have: velocity limiter support, rope sheave assembly, ratchet assembly, stage clip, brake scotch etc., but there is not wire holder, it is characterized in that: two electric switches of velocity limiter---safety return circuit switch 6 and trigger switch 5 are the same side that is arranged in support side plate 1 up and down, wherein: safety return circuit switch 6 is fixed installation, but trigger switch 5 horizontal displacements, by its position of parallel motion adjustment; Described velocity limiter also comprises an eccentric mechanism 2 and pull bar 8, and eccentric mechanism 2 is arranged on the same support side plate 1 of electric switch; On the rope sheave web of described velocity limiter trip(ping) bar 10 is housed.
The eccentric mechanism 2 of described velocity limiter comprises: eccentric wheel 12, eccentric key 13, screw 11 constitute, and a place is connected with support side plate 1 by eccentric key 13.
The afterbody of the trip(ping) bar 10 of described velocity limiter extends and can touch mutually with eccentric wheel 12, velocity limiter generation mechanical action when trip(ping) bar 10 rotates disengaging ratchet 7.
The material of the trip(ping) bar 10 of described velocity limiter is an aluminum alloy.
The front end of the pull bar 8 of described velocity limiter moves 7～10 millimeters towards the switch direction, can touch mutually with safety return circuit switch 6 and make switch motion.
One side of the support side plate 1 of described velocity limiter is increased 20～40 millimeters.
The trigger switch 5 of described velocity limiter is realized horizontal displacement by the waist hole that at least one cover is set with cooperating of screw.
Described velocity limiter has extension spring 3, and an end of extension spring 3 is fixing through screw and eccentric mechanism 2, and the other end and plate washer 4 are fixing.
Accompanying drawing 1-3 represents preferred forms of the present utility model.
Principle of work of the present utility model is: when elevator moved downwards, the rope sheave 9 of velocity limiter rotated, and when the rotating speed of rope sheave had reached electrical action speed, safety return circuit switch 6 began action, blocks power supply, and elevator traction machine stops operating.If elevator since action of inertia continue hypervelocity downwards towards the time, velocity limiter generation mechanical action lifts the safety tongs system and makes the deceleration of elevator stop.And when upwards operation hypervelocity of elevator, same as above, also be safety return circuit switch 6 action earlier.If elevator because inertia continues hypervelocity to upper punch, and trigger switch 5 will move, causes the wire holder action and makes the deceleration of elevator stop.
In addition, elevator under arbitrary speed, has rotated eccentric wheel 12 artificially when Acceptance Test, make its afterbody that touches trip(ping) bar 10, trip(ping) bar 10 rotates throws off, ratchet 7 actions, cause velocity limiter generation mechanical action, lift the safety tongs system, reach the purpose of acceptance of lift test.
This shows that the change of the utility model by two switch arrangement positions not only makes the height of velocity limiter be minimized, nor can shaking on the support glides causes elevator accident because of switch is contained in.The utility model can make velocity limiter generation mechanical action under arbitrary speed, make velocity limiter-safety tongs can linkage test.
A kind of organic machine room-free elevator velocity limiter that the utility model provides; only done detailed description with regard to illustrated embodiments; but can not be interpreted as the restriction of other modes that the utility model is implemented; everyly further improve and similar or identical scheme on the utility model basis, all being considered as is the scope that the utility model is asked for protection.
