Abstract
The utility model discloses a progressive safety device comprising a tension rod (1), a guide wheel seat (2), a slider (3) and a safety clamp seat (4). The upper and lower ends of the tension rod are provided with tension arms (12); the other end part (13) of the tension arm (12) is hinged on the safety clamp seat (4) and the middle part (14) is provided with a link device (15); the guide wheel seat (2) is provided with a connecting plate (21); the safety clamp seat (4) is in float connection with the guide wheel seat (2); the safety clamp seat (4) is provided with a slider (3) divided into a movable slider (31) and a fixed slider (32); and the movable slider (31) is hinged with the link device (15). The utility model has reasonable design and compact structure, sets braking sliders to be movable sliders and fixed sliders connected with the clamp seat flexibly, relieves impact force to a suspension cage and a guide rail during braking so as to ensure soft landing of the suspension cage, thereby prolonging the service life of the guide rail and the suspension cage.
Description
Technical field
The utility model relates to a kind of gradual safety, specifically a kind of gradual safety of building hoist.
Background technology
The safety apparatus of construction is the hardware device that is related to workmen's life security, its safe handling that directly has influence on operating personal whether reasonable in design.In the manipulating of reality, cage is usually with higher speed operation, use comparatively frequent, steel rope is worked in the fatigue of being everlasting, wire cable rupture, cage fall, personal casualty, guide rail damage etc. also are recurrent accidents, solution that China's utility model patent synchronous self locking safety pincers (CN 200420017782.1) are reliable this key issue of falling suddenly of causing of reasons such as elevator craning cage wire cable rupture, but still fail to solve the accident problem that the non-fracture of steel rope is fallen or the cage overspeed that causes because of other reasons is caused.Present another kind hypervelocity safety catch is arranged on the top of elevator, to brake device for carrying out said is arranged on the guide rail, connect by steel rope between the two, this device steel rope trip path is long, braking retardation, and the stressed variation fluctuation range of steel wire rope tension is bigger in braking procedure, in the fatiguability, careless slightly will the fracture, often premature failure.
Summary of the invention
The variety of problems that the utility model exists in practical operation in view of prior art, the spy provides a kind of rail clamping type progressive safety.
The technical scheme that the utility model solves existing issue is a kind of gradual safety, comprise pull bar, guiding wheel seat, slide block, safety gear block, it is characterized in that: the pull bar upper end is provided with joint, the other end is provided with torque arm, torque arm the other end is articulated on the safety gear block, the middle part is provided with linkage, the guiding wheel seat is provided with connecting panel, safety gear block floats with the guiding wheel seat and is connected, safety gear block is provided with slide block, described slide block is made as movable slider and fixing slide block, and movable slider and linkage are hinged.
Fixedly slide block described in the utility model is fixed on the safety gear block with fly nut.
Safety gear block described in the utility model and guiding wheel seat float to be connected and are provided with ball between being.
The utility model compared with prior art, its beneficial effect is: brake silpper is set to movable slider and fixing slide block, flexibly connect with the pincers seat, actv. is buffer-braking power in braking procedure, alleviate the impulsive force of glancing impact to cage and guide rail, make cage braking soft landing, thereby prolong the life-span of guide rail and cage.The utility model is reasonable in design, compact conformation, and braking does not damage guide rail, the braking highly effective and safe.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model back view.
The specific embodiment
Referring to accompanying drawing 1-2, the implementation case comprises: pull bar 1, guiding wheel seat 2, slide block 3, safety gear block 4, it is characterized in that: pull bar 1 upper end is provided with joint 11, joint 11 connects the speed limit chest expander, the other end is provided with torque arm 12, torque arm the other end 13 is articulated on the safety gear block 4, middle part 14 is provided with linkage 15, guiding wheel seat 2 is provided with connecting panel 21, connecting panel 21 is connected with cage 6, and safety gear block 4 is provided with ball 41, and guiding wheel seat 2 floats on the ball 41, safety gear block 4 is provided with spring installation 42, promptly be convenient to safety gear block 4 and keep normality with guiding wheel seat 2, safety gear block 4 is provided with accurately machined groove, is used for fixing slide block 3, slide block 3 is made as movable slider 31 and fixing slide block 32, and movable slider 31 is hinged with linkage 15.Fixedly slide block 32 usefulness fly nuts 43 and spring are fixed on the safety gear block 4.
When the utility model normally uses, set certain clearance between slide block 3 and the guide rail 5, when cage 6 exceeds the speed limit because of certain reason, pull bar 1 is instigated torque arm 12 under the effect of speed limit pulling force, torque arm 12 is instigated movable slider 31 oblique guide rails 6 by linkage 15 and is slided, be adjacent to guide rail 6, because floating with guiding wheel seat 2, safety gear block 4 is connected, under the antagonistic force of guide rail 6 and movable slider 31, safety gear block 4 moves, and makes fixedly slide block 32 also be close to guide rail 6, and movable slider 31 is constantly pressed close to guide rail 6 under the friction force effect, slide block 3 and guide rail 6 paste near more more, until cage 6 is fixed on the guide rail 6, with cage 6 stops, because of fixedly connecting with fly nut 43 elasticity between slide block 32 and the safety seat 4, a progressive process is arranged in braking procedure, reduce the impact of braking cage.
Claims (3)
1, a kind of gradual safety, comprise pull bar (1), guiding wheel seat (2), slide block (3), safety gear block (4), it is characterized in that: the pull bar upper and lower side is provided with torque arm (12), torque arm (12) the other end (13) is articulated on the safety gear block (4), middle part (14) is provided with linkage (15), guiding wheel seat (2) is provided with connecting panel (21), safety gear block (4) floats with guiding wheel seat (2) and is connected, safety gear block (4) is provided with slide block (3), described slide block (3) is made as movable slider (31) and fixing slide block (32), and movable slider (31) is hinged with linkage (15).
