Abstract
The invention discloses a safety gear linkage device, comprising a main safety gear body. A crank of the main safety gear body is fixedly connected with a first linkage support, a base of the main safety gear body is rotatably connected with a second linkage support, a connecting rod is connected between the first support and the second support, and the second support is further fixedly connected with a third linkage support which is fixedly connected with a lifting plate. The safety gear linkage device solves the problem that the linkage of a safety gear needs to be implemented by a lifting rod in the prior art, the linkage device is arranged on the crank of the main safety gear body to replace the lifting rod, and a lower beam structure can be integral, so that not only is the cost saved, but also the safety gear linkage device can be subjected to independent production and is simple in process and convenient to install.
Description
Technical field
The present invention relates to a kind of safety tongs linkage, belonged to the elevator production technical field.
Background technology
Safety tongs is under the manipulation of velocity limiter, after the 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.
Existing safety tongs all is to drive crank by lifting rod to rotate, thereby realize the safety tongs braking, but general elevator manufacturer does not all produce the equipment of lifting rod voluntarily, need to go market purchasing, not only cost is higher, and can't purchase and need the time, the production cycle of safety tongs can't be controlled voluntarily.
Background technology
Technical matters to be solved by this invention provides a kind of safety tongs linkage, by in the safety tongs main body linkage being installed, has replaced lifting rod, has saved cost, installs more convenient.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of safety tongs linkage, comprise the safety tongs main body, be fixedly connected with the first interlock support on the crank of described safety tongs main body, the second interlock support has been rotatably connected on the pedestal of described safety tongs main body, be connected with trace between described the first support and the second support, described the second support also is fixedly connected with the 3rd interlock support, is fixedly connected with on described the 3rd interlock support and lifts plate.
Aforesaid safety tongs linkage is characterized in that: the described two ends that lift plate are separately installed with the cable wire sheath.
The invention has the beneficial effects as follows: by at the crank of safety tongs main body linkage being installed, replaced lifting rod, and lower girder construction can be made of one formula, not only save cost, but and autonomous production, technique is simple, easy for installation.
Description of drawings
Fig. 1 is the structural representation of a kind of safety tongs linkage of the present invention.
The specific embodiment
Below in conjunction with Figure of description, the present invention is further illustrated.
As shown in Figure 1, a kind of safety tongs linkage, comprise safety tongs main body 1, be fixedly connected with the first interlock support 3 on the crank 2 of safety tongs main body 1, the second interlock support 5 has been rotatably connected on the pedestal 9 of safety tongs main body 1, being connected with trace 4, the second supports 5 between the first support 3 and the second support 5 also is fixedly connected with to be fixedly connected with on the 3rd interlock support 6, the three interlock supports 6 and lifts plate 7.
Lift plate 7 by upwards spurring, thereby driving the 3rd interlock support 6 upwards rotates, the second interlock support 5 is rotated take the point of connection of itself and pedestal 9 as fulcrum, thereby driving the first support 3 by trace 4 rotates, the crank 2 of captiveing joint with the first support 3 is upwards rotated, realized the normal operation of safety tongs.
The two ends that lift plate 7 are separately installed with cable wire sheath 8, and are lighter, convenient when lifting edition by cable wire sheath 8 pulling.
In sum, a kind of safety tongs linkage provided by the invention by in the safety tongs main body linkage being installed, has replaced lifting rod, has saved cost, installs more convenient.
More than show and described groundwork of the present invention, principal character and advantage.The technical personnel of the industry should be understood; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is by appending claims and equivalent circle thereof.
