Abstract
The invention discloses a linkage structure for safety gears, which comprises two safety gears and is characterized in that trigger mechanisms of the two safety gears are connected through a connecting rod. Linkage of the two safety gears is achieved by the aid of the connecting rod, so that the safety gears can take action simultaneously in brake, braking force is divided, and an elevator is protected while damages to the safety gears are avoided. The linkage structure for safety gears has the advantages of simple structure, safety and reliability.
Description
Technical field
The invention belongs to elevator and make the field, relate in particular to a kind of linkage structure of carving piece type safety tongs.
Background technology
The elevator safety clamp device is under the manipulation of velocity limiter, after very serious fault such as hypervelocity, disconnected rope appears in elevator, with the urgent stop of car and be clamped in a kind of safety device on the guide rail.It provides the actv. protective effect to the safe operation of elevator, generally it is installed on car frame or the counterweight frame.With the proposition that work car up-running over-speed protection requires, bidirectional safety tongs has use more widely now.Safety tongs device partly is made up of safety tongs steering unit and safety block two.When being the safety tongs mechanism action, at first touching electrical apparatus mechanism and make elevator safety loop break off stop elevator, if drg can't stop the time safety tongs will further move, make elevator stopping on guide rail.At present elevator can be divided into three kinds of the piece type of carving, eccentric wheel type and roller-types with safety tongs according to the difference of its braking element version.Carve piece type safety tongs at glancing impact, mention wedge, just can be stuck on the guide rail.At present, elevator can respectively be provided with a safety tongs on two vertical guide rails, do not link between two safety tongss, and is separate.Therefore, a safety tongs often occurs and triggered and brake, and another does not have situation about triggering.When this situation occurring, can take place to make safety tongs that serious deformation take place and cause damage, simultaneously the also safety of serious elevator because braking force is not enough.
Summary of the invention
The invention provides a kind of solution of the above problems, a kind of safety tongs linkage structure simple in structure is provided.
Technical scheme of the present invention is a kind of safety tongs linkage structure, and it comprises two safety tongss, it is characterized in that: connect through connecting rod between the trigger mechanism of two said safety tongss.
Preferably, the trigger mechanism of said safety tongs connects said connecting rod through flange.
A kind of safety tongs linkage structure of the present invention is realized making the interlock of two safety tongss them to have an effect simultaneously at glancing impact, thereby share braking force through connecting rod, in the time of the protection elevator safety, also avoids safety tongs itself to be destroyed.A kind of safety tongs linkage structure of the present invention has simple in structure, safe and reliable advantage.
Description of drawings
Fig. 1 is the structural representation of a kind of safety tongs linkage structure of the present invention;
Fig. 2 is the partial enlarged drawing at A place among Fig. 1.
The specific embodiment
Following specific embodiments of the invention is described in further detail.
As depicted in figs. 1 and 2, a kind of safety tongs linkage structure of the present invention comprises between the trigger mechanism 12 of two safety tongs 10, two safety tongss 10 and connects connecting rod through flange, realizes interlock through connecting rod.So just can be any therein during 10 actions of a safety tongs, can trigger another safety tongs 10 and move simultaneously, strengthened safety.
Above embodiment is merely the present invention's a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the present invention's design, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with accompanying claims.
Claims (2)
1. safety tongs linkage structure, it comprises two safety tongss, it is characterized in that: connect through connecting rod between the trigger mechanism of two said safety tongss.
2. a kind of safety tongs linkage structure according to claim 1, it is characterized in that: the trigger mechanism of said safety tongs connects said connecting rod through flange.
