Abstract

The utility model discloses a kind of intelligent and safe pincers, safety tongs body (1) including band lifting rod (2), safety tongs body (1) is provided with the lead (3) being parallel to lifting rod (2), being arranged with translation disk (4) on lead (3), translation disk (4) is fixed with lifting rod (2);Described lead (3) is provided with multiple detection contact (8).The performance state of safety tongs can be monitored by this utility model, thus can prevent from occurring unexpectedly.

Description

Intelligent and safe clamps
Technical field
This utility model relates to a kind of elevator safety assembly, particularly a kind of intelligent and safe pincers.
Background technology
Elevator safety clamp device is under the manipulation of limiter of speed, when elevator speed exceedes the restriction speed that elevator governor sets Degree, or suspension strop occur fracture and lax in the case of, by urgent for car stop a kind of safety dress of being clamped on guide rail Put.It provides effective protective effect to the safe operation of elevator, is typically installed on car frame or counterweight frame.
But existing safety tongs is purely mechanic structure, it is difficult to when safety tongs breaks down be noticeable.Pacify as elevator One defence line of full most critical, once safety tongs breaks down, and consequence is by extremely serious.
Utility model content
The purpose of this utility model is, it is provided that a kind of intelligent and safe pincers.The performance state of safety tongs can be supervised by it Control, thus can prevent from occurring unexpectedly.
The technical solution of the utility model: intelligent and safe clamps, and is characterized in: include the safety tongs body of band lifting rod, peace Full pincers body is provided with the lead being parallel to lifting rod, and lead is arranged with translation disk, and translation disk is fixed with lifting rod, institute State lead and be provided with multiple detection contact.
In above-mentioned intelligent and safe pincers, described translation disk is fixedly arranged above armature, and armature is arranged over electric magnet;Electric magnet Being fixed on bearing, bearing is fixed with safety tongs body.By controlling electric magnet action, carry out the duty of simulating Safety pincers.
In aforesaid intelligent and safe pincers, between described armature and electric magnet, it is provided with back-moving spring.
In aforesaid intelligent and safe pincers, in the voussoir of described safety tongs body, it is provided with temperature sensor, by detection wedge The temperature of block assesses the frictional force of voussoir.
Compared with prior art, this utility model by arrange on safety tongs body can on lead movement put down Shifting dish, and the movement of translation disk is directly by lifting rod control, it is possible to come according to translation disk displacement on lead Judge the action situation of lifting rod, such that it is able to the performance of safety tongs is detected, to improve the safety of elevator.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Being labeled as in accompanying drawing: 1-safety tongs body, 2-band lifting rod, 3-lead, 4-translation disk, 5-armature, 6-electricity Magnet, 7-bearing, 8-detects contact.
Detailed description of the invention
With embodiment, this utility model is further described below in conjunction with the accompanying drawings, but is not intended as this utility model The foundation limited.
Embodiment.Intelligent and safe clamps, as shown in Figure 1: include the safety tongs body 1 of band lifting rod 2, on safety tongs body 1 Being provided with the lead 3 being parallel to lifting rod 2, lead 3 is arranged with translation disk 4, translation disk 4 is fixed with lifting rod 2;Described lead It is provided with multiple detection contact 8 to post 3.Described translation disk 4 is fixedly arranged above armature 5, and armature 5 is arranged over electric magnet 6;Electromagnetism Ferrum 6 is fixed on bearing 7, and bearing 7 is fixed with safety tongs body 1.It is provided with back-moving spring between described armature 5 and electric magnet 6.Institute It is provided with temperature sensor in stating the voussoir of safety tongs body 1.
Operation principle of the present utility model: when lifting rod pulls voussoir to be braked, the pull distance of lifting rod is permissible Being embodied on lead by translation disk, the detection contact of lead can get this range information, according to this range information Whether exceed threshold value, then can determine whether whether safety tongs exists potential safety hazard.And the only just meeting when elevator faults due to safety tongs Triggering, the chance therefore triggered is not a lot, it is possible to controls electric magnet action and carrys out the action of simulating Safety pincers.
