Description
Technical field
The present invention relates to a kind of antidetonation derailing elevator, belong to elevator safety technical field.
Background technology
In the multiple area of earthquake, the use of elevator is faced with a very difficult test.Because vibrations can cause cage guide, counterweight and one of car generation are helped to the power of shaking, make to lead boots and be easy to occur derailment occurring, if there is derailment occurring, elevator is out of service not in time, very likely occurs great personal casualty event.
In existing elevator, there are some elevators to adopt the contact arm on piano steel wire and the counterweight arranging with guide rail parallel, as the scheme of recording in the patent documentation of TOHKEMY 2003-321169 communique, in the time of derailing, whether contact arm contacts with steel rope, derail thereby can detect.But this structure, due to the spring being arranged between counterweight and guide rail, even the very little bending of guide rail all can make counterweight that larger horizontal displacement occurs, makes contact arm contact with piano steel wire, produces flase drop.
In order to solve the above problems, the Chinese patent that publication number is CN101628677A, has recorded by support unit the contact of ring-type has been arranged on to the unsteady technical scheme on boots of leading.This scheme, although can make contact avoid counterweight to be subjected to displacement produced impact, thus avoid producing flase drop.But that floats leads boots, certainly will reduce and lead the be subject to force intensity of boots to guide rail, so when this scheme is avoided producing flase drop, also increased the possibility of derailing.
Summary of the invention
The object of the invention is to, a kind of antidetonation derailing elevator is provided.The present invention can lead under the prerequisite that boots are subject to force intensity not affecting, and can depart from and lead boots and detect in time guide rail, and can avoid the generation of flase drop phenomenon.
Technical scheme of the present invention: a kind of antidetonation derailing elevator, comprise the guide rail in elevator hoistways, remaining part, with reference to conventional elevator structure, is characterized in: the guide rail in elevator hoistways be limited in horizontal section for "
" the leading in boots of type, and lead and in boots, be also provided with the U-shaped boots pad of leading; Leading on boots, be adhesive with piezoelectric ceramic piece by adhesive agent; Piezoelectric ceramic piece is provided with pressure backboard outward, and pressure backboard surrounding is symmetrical arranged respectively 4 magnetic posts, and the rib of leading boots is provided with the perforation corresponding with magnetic post, and 4 magnetic posts are arranged in perforation, thereby pressure backboard is covered on piezoelectric ceramic piece; On piezoelectric ceramic piece, be also connected with signal wire (SW), the signal wire (SW) other end connects in AD converter, and AD converter is connected with apparatus for controlling elevator.
Because the material of guide rail has ferrimagnetism, in the time that guide rail is in leading boots, guide rail produces an attractive force to 4 magnetic posts, magnetic post pulls pressure backboard, make pressure backboard to piezoelectric ceramic piece produce a pressure, so guide rail in the time of normal position, piezoelectric ceramic piece is in pressurized deformed state.In the time that guide rail departs from, the magnetic force that magnetic post is subject to guide rail disappears, and then the pressure that piezoelectric ceramic piece is subject to changes, now piezoelectric ceramic piece will produce a voltage signal, this voltage signal is after signal wire (SW) arrival AD converter is processed, enter apparatus for controlling elevator, make apparatus for controlling elevator can brake in time elevator, avoid the generation of accident.
In above-mentioned antidetonation derailing elevator, install for convenient, described pressure backboard is ferromagnetic material.Conventionally be also to adopt ferromagnetic material owing to leading boots, under the effect of magnetic post, the pressure back of the body is magnetized by magnetic post, can naturally be adsorbed on and lead on boots, even derailing, magnetic post is not subject to the pulling force of guide rail, and pressure backboard also can not come off from leading boots.
In aforesaid antidetonation derailing elevator, for the pressure that balanced piezoelectric ceramic piece is subject to, also prevent the impaired destruction of electroceramics sheet, the described piezoelectric ceramic piece back side is also bonded with silica gel pad simultaneously.
In aforesaid antidetonation derailing elevator, described in lead boots horizontal section for "
" type, comprise three ribs, wherein two parallel, and perpendicular to the 3rd rib; Lead boots two ends and be provided with brace panel, brace panel is to connect the triangular structure of leading orthogonal two ribs of boots, and the brace panel at upper and lower two ends forms a protection zone to piezoelectric ceramic piece.Brace panel is in strengthening leading boots intensity; also can form a guard space, not only can prevent that other parts in hoistway from touching pressure backboard, also can play the grease proofing effect of water proof and dust proof; make electronic component of the present invention in efficient protected state, thereby can stablize operation effectively.
Compared with prior art, the present invention is the action triggers parts as elevator derailing by magnetic post, then send parts using piezoelectric ceramic piece as induced signal, make the detection of elevator derailing more precisely convenient.By contrast, in the contact measurement of employing contact and detection line mode, easily occur that foreign object triggers the generation of flase drop phenomenon, as the publication number Chinese patent that is CN101628677A, long detection line is set in hoistway, detection line is received after the disturbance of the parts such as the trailing cable rocking in hoistway, is very likely triggered flase drop.The present invention is all arranged on all parts that detect to lead on boots, and structure is small and exquisite simplifies, and the possibility that affected by foreign object is lower, therefore detects more precisely stable.The present invention not only takes full advantage of the ferromagnetic material characteristic of cage guide, guide rail is departed to action and be converted into the disappearance of signal of magnetic force, then by the piezoeffect of piezoelectric ceramic piece, magnetic force signal is converted into electric signal, directly applies to apparatus for controlling elevator; And the present invention also takes full advantage of the ferromagnetic material characteristic of elevator guide shoe, parts of the present invention are installed very easy, be connected and fixed mode without any need for screw, rivet etc., dismounting is all very convenient.
