Abstract
The utility model discloses a safety gear lifting mechanism. A master brake bar and a slave break bar are parallel to each other and are welded to the two ends of a linkage bar respectively, the other end of the master brake bar is connected with a steel wire rope connecting plate, the other end of the slave brake bar is connected with a first lifting bar, reset springs are arranged at the positions close to the two ends of the linkage bar respectively, an electric switch is arranged between the reset springs, and a second lifting bar parallel to the first lifting bar is further arranged on the master brake bar. According to the safety gear lifting mechanism, the two lifting bars are welded onto the linkage bar, when a speed limiter drives the master brake bar to act, translational motion of a whole system enables the master brake bar and the slave brake bar to act synchronously, and the lifting bars lift a safety gear to realize the function of the safety gear. Through the structure, the cost is lowered, the needed well space is small, operation is simple and convenient, secondary transmission is reduced, the brake speed is high and the safety gear lifting mechanism is safer and more reliable.
Description
Technical field
The utility model relates to a kind of lift appliance, is specifically related to a kind of safety tongs shift mechanism.
Background technology
Elevator safety clamp device is under the manipulation of velocity limiter, when elevator speed exceedes the limited speed that elevator governor is set, or fracture occurs and lax in the situation that at suspension strop, by urgent car stop and be clamped in a kind of safety device on guide rail.It provides actv. protective effect to the safe operation of elevator, is generally arranged on car frame or counterweight frame.Thereby existing safety tongs shift mechanism is mostly to carry by rotarily driving on crank rotation drive lifting rod of axle, safety tongs is lifted to brake and be fixed on car guide rail, this shift mechanism complex structure, and cost is higher.
Summary of the invention
For addressing the above problem, the purpose of this utility model is to provide a kind of safety tongs shift mechanism, simple in structure, reduces secondary transmission, and retro-speed is fast, more safe and reliable; Reduce costs, the hoistway space needing is little.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of safety tongs shift mechanism, comprises trace, main brake bar, and from brake rod, the first lifting rod, the second lifting rod, retracing spring, electric switch;
Described main brake bar and be describedly parallel to each other from brake rod, be welded on respectively the two ends of described trace, the other end connecting steel wire ropes connecting panel of described main brake bar, the described other end from brake rod connects described the first lifting rod, described trace is respectively arranged with described retracing spring near near at two ends, described electric switch is arranged between described retracing spring, is also provided with described the second lifting rod paralleling with described the first lifting rod on described main brake bar.
Further, the steel rope of the fixing velocity limiter of described steel rope connecting panel and velocity limiter expansion tightening wheel.
Further, described shift mechanism is installed on upper beam assembly, and described shift mechanism is connected with the safety tongs on curb girder assembly with described the second lifting rod by described the first lifting rod.
The beneficial effects of the utility model are:
The utility model is welded on two lifting rods on trace, in the time that velocity limiter drives the action of main brake bar, the translation of whole system makes to move from brake rod and main brake bar simultaneously, lifting rod is mentioned safety tongs to realize its function, and this infrastructure cost is reduced, and the hoistway space needing is little, easy and simple to handle, reduced secondary transmission, retro-speed is fast, more safe and reliable.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of specification sheets, below with preferred embodiment of the present utility model and coordinate accompanying drawing to be described in detail as follows.Detailed description of the invention of the present utility model is provided in detail by following examples and accompanying drawing thereof.
