Abstract
The utility model relates to the technical field of lifts, in particular to a lifting mechanism of counter-weight safety tongs, which comprises two groups of safety tongs arranged on the left side and the right side of the bottom of a counter-weight frame. The two groups of safety tongs are connected with each other through a linkage mechanism and provided with movable wedge blocks and connecting members hinged to the movable wedge blocks, the connecting members can rotate around a supporting point, a connecting member corresponding to one of the two groups of the safety tongs is hinged to a lifting handle, and the lifting handle is connected with a steel wire rope of a counter-weight speed limiter. By adopting the structure, the lifting mechanism of the counter-weight safety tongs has the advantages of being compact in structure, safe and reliable in movement and suitable for being installed on the counter-weight frame in a narrow and small space.
Description
Technical field:
The utility model relates to the elevator technology field, relates in particular to a kind of counterweight safety shift mechanism.
Background technology:
Elevator be a kind of be the vertical conveyor of power with the electrical motor, case shape gondola is housed, be used for tier building and take advantage of people or carrying goods.Elevator is as the transport facility of vertical direction, become important Architectural Equipment in skyscraper and public place and indispensable.The development of Along with computer technology, automatic technology and Power Electronic Technique, modem elevator have become the representative type electromechanical integrated product.Raising along with whole national economy strength; The people's personal consumption level rises appreciably; The real estate developer releases medium-to-high grade little high level and high-rise residential building one after another energetically, has driven increasing rapidly of residential lift, becomes the main growth point in whole elevator market.Existing elevator, when hoistway space hour, the installing space of counterweight frame is comparatively narrow and small; Existing counterweight safety shift mechanism, because mechanism's more complicated, the space of effect is bigger; Not only can't be applicable to the situation that installing space is comparatively narrow and small, and action is safe and reliable inadequately.
The utility model content:
The purpose of the utility model is to the deficiency of prior art a kind of counterweight safety shift mechanism to be provided, and its compact conformation, action are safe and reliable, are applicable on the counterweight frame that is installed in small space.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of counterweight safety shift mechanism; It comprises two groups of safety tongss that are arranged at the left and right sides, counterweight frame bottom, interconnects through interlinked mechanism between two groups of safety tongss, and two groups of safety tongss are provided with movable voussoir; Two groups of safety tongss are provided with voussoir pivotally attached attaching parts movable with it; Attaching parts can be around fulcrum rotation, and wherein one group of pairing attaching parts of safety tongs is hinged with and lifts hand, and this lifts hand and connects the counterweight speed limiter wire rope.
Said interlinked mechanism is a pipe link, and the two ends of pipe link are connected to two groups of pairing attaching partss of safety tongs.
The two ends of said pipe link are provided with spring.
The utility model beneficial effect is:
The said a kind of counterweight safety shift mechanism of the utility model; It comprises two groups of safety tongss that are arranged at the left and right sides, counterweight frame bottom, interconnects through interlinked mechanism between two groups of safety tongss, and two groups of safety tongss are provided with movable voussoir; Two groups of safety tongss are provided with voussoir pivotally attached attaching parts movable with it; Attaching parts can be around fulcrum rotation, and wherein one group of pairing attaching parts of safety tongs is hinged with and lifts hand, and this lifts hand and connects the counterweight speed limiter wire rope.Adopt the counterweight safety shift mechanism of said structure, have compact conformation, the safe and reliable advantage of action, be applicable on the counterweight frame that is installed in small space.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the side schematic view of the utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
As depicted in figs. 1 and 2; The described a kind of counterweight safety shift mechanism of the utility model, its structure are that it comprises two groups of safety tongss 8 that are arranged at the left and right sides, counterweight frame bottom; Interconnect through interlinked mechanism between two groups of safety tongss 8; Two groups of safety tongss 8 are provided with 3, two groups of safety tongss 8 of movable voussoir and are provided with voussoir 3 pivotally attached attaching partss 6 movable with it, and attaching parts 6 can rotate around a fulcrum; Wherein one group of safety tongs 8 pairing attaching parts 6 is hinged with and lifts hand 7, and this lifts hand 7 and connects the counterweight speed limiter wire rope.Further, said interlinked mechanism is a pipe link 10, and the two ends of pipe link 10 are connected to two groups of safety tongss, 8 pairing attaching partss 6, further, the two ends of said pipe link 10 are provided with spring 11, and are more stable when making pipe link 10 actions.
The described a kind of counterweight safety shift mechanism of the utility model, its principle of work be, when the downward running velocity of counterweight frame surpass command speed 115% the time; The action of counterweight velocity limiter; Block the counterweight speed limiter wire rope, the said hand 7 that lifts is upwards mentioned under the effect of speed limiter wire rope, drives attaching parts 6 and upwards rotates; The attaching parts 6 that pipe link 10 then drives opposite side upwards rotates; Thereby the movable voussoir 3 that drives safety tongs 8 is upwards mentioned, and makes the voussoir of safety tongs 8 clamp the counterweight guide rail, thereby makes the counterweight frame stop on the counterweight guide rail.Hand 7 to the counterweight frame centre distance minimum that lifts of the utility model can be 120mm, has compact conformation, the safe and reliable advantage of action, is applicable on the counterweight frame that is installed in small space.
The above only is the preferred embodiments of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
