Abstract
The utility model provides a device for preventing accidental movement of elevator cage, includes clutch blocks and tensile structure, wherein: tensile structure is fixed in U type mount both sides, the clutch blocks is located T type guide rail both sides, tension mechanism includes guide cover board, guide block, spring holder, pull rod and electro -magnet, the guide block clamp is between two guide cover boards to pass through the bolt fastening, the guide block is fixed at U type mount inboardly, the clutch blocks is located between the guide cover board, mounting hole and clutch blocks middle part one end that the pull rod passed U type mount and guide block articulate, and the other end and the spring holder that is located the U type mount outside of pull rod articulate, the spring holder external member has the spring, and the other end and the electro -magnet of spring holder are connected, the utility model discloses simple structure, but float mounting adopts electromagnetic drive in the elevator guide rail both sides, can brake the car rapidly, prevents that the unexpected removal of car from causing harm.
Description
Technical field
This utility model relates to elevator technology field, particularly a kind of device preventing accidental movement of elevator cage.
Background technology
Accidental movement of elevator cage is that car door is opened after Elevator landing, and during passenger turnover elevator, car surprisingly moves up or down suddenly. So can cause casualties accident. The reason of its accidental movement is a lot, and in order to avoid the injury caused because of car accidental movement, each elevator company all prevents accidental movement of elevator cage device in research and development.
Commercially common are following several ways to solve problems at present. One is adopt rail clamping device, when car generation accidental movement, system sends instruction, rail clamping device action, is clamped on cage guide by car. Its cost is high, and the cost adding elevator is unfavorable for selling. One is adopt rope brake, when car accidental movement, and rope brake action. Its cost is low, but in some cases, can not avoid the generation of car accidental movement completely. One is adopt bidirectional safety tongs, but its speed of action can not be completely secured its effectiveness, and structure is complicated, can increase the pit depth of elevator hoistways, and cost increases relatively. Also have some other modes, but structure is all very complicated.
Summary of the invention
In order to overcome the disadvantages mentioned above of prior art, the purpose of this utility model is to provide a kind of simple in construction, and cost increases few, and can effectively prevent the device that car accidental movement occurs
This utility model solves its technical problem and be the technical scheme is that
A kind of device preventing accidental movement of elevator cage, including brake pad and stretching structure, wherein: described stretching structure is fixed on U-shaped fixed mount both sides, described brake pad is positioned at T-shaped guide rail both sides, described drawing mechanism includes defelctor apron, guide pad, spring base, pull bar and electric magnet, described guide pad is clipped between two defelctor aprons, and be bolted, described guide pad is fixed on inside U-shaped fixed mount, described brake pad is between defelctor apron, in the middle part of the installing hole of the described pull bar U-shaped fixed mount of traverse and guide pad and brake pad, one end is hinged, the other end of pull bar is hinged with the spring base being positioned at outside U-shaped fixed mount, described spring base external member has spring, the other end of spring base is connected with electric magnet.
As further improvement of the utility model: described brake pad adopts elastic abrasion-proof material to make, including elastomeric material.
As further improvement of the utility model: described U-shaped fixed mount adopts leaf spring to make.
Compared with prior art, the beneficial effects of the utility model are: this utility model simple in construction, U-shaped fixed mount may be installed outside car, floats in cage guide both sides, by Electromagnetic Drive brake pad, Bidirectional clamping cage guide, avoid the link gear of complexity, simultaneously that the transformation of original elevator structure is few, just can accomplish effectively to prevent the transmission of car accidental movement, improvement cost increases few, can extensively send out and be applied to strengthen in lift facility security fields.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is top cross sectional view of the present utility model.
Detailed description of the invention
Illustrate with embodiment, this utility model to be further illustrated in conjunction with accompanying drawing:
Referring to figs. 1 to Fig. 2, a kind of device preventing accidental movement of elevator cage, including brake pad 1 and stretching structure 2, wherein: described stretching structure 2 is fixed on U-shaped fixed mount 3 both sides, described U-shaped fixed mount 3 adopts leaf spring to make, described brake pad 1 is positioned at T-shaped guide rail 4 both sides, described drawing mechanism 2 includes defelctor apron 21, guide pad 22, spring base 23, pull bar 24 and electric magnet 25, described guide pad 22 is clipped between two defelctor aprons 21, and be bolted, described guide pad 21 is fixed on inside U-shaped fixed mount 3, described brake pad 1 is between defelctor apron 21, in the middle part of the installing hole of the described pull bar 24 U-shaped fixed mount of traverse and guide pad and brake pad 1, one end is hinged, the other end of pull bar 24 is hinged with the spring base 23 being positioned at outside U-shaped fixed mount, described spring base 23 external member has spring 26, the other end of spring base 23 is connected with electric magnet 25.
Described brake pad 1 adopts elastic abrasion-proof material to make, including elastomeric material.
When elevator sends accidental movement, alarm signal controls electric magnet action, electric magnet drives pull bar to be pulled outwardly brake pad, in the middle of brake pad after stress, and both sides projection angle cage guide, lift car just stops accidental movement, when caution signals releasing recovers normal, electric magnet dead electricity, springs return spring base, brake pad resiles, and floats on cage guide.
In sum; after those of ordinary skill in the art reads this utility model file; conceive according to the technical solution of the utility model and technology and make other various corresponding conversion scheme without creative mental work, belong to the scope that this utility model is protected.
