Abstract
The utility model discloses a sliding tandem unbalanced load control safety clamp connecting mechanism. A sliding mechanism is arranged between a safety clamp seat and a carrier, changing the old rigid connection therebetween into sliding connection. The sliding mechanism is a dovetail sliding mechanism and consists of an upper drag harrow and a lower drag harrow. The upper drag harrow is rigidly connected at the bottom of the carrier and the lower drag harrow is rigidly connected on the clamp seat. The sliding tandem unbalanced load control safety clamp connecting mechanism effectively eliminates bad influence to the safety clamp from swinging of the unbalanced load of the carrier and greatly improves the practicability and popularizing rate of the speed restricting and drop preventing systems. The sliding tandem unbalanced load control safety clamp connecting mechanism is simple in structure, low in cost, easy to make, safe and reliable, and is suitable for vertical lifting machines driven by wire rope traction or chains, particularly for large heavy vertical lifting devices like large vertical garages, large vertical lifting devices used at wharfs, and large elevators.
Description
Technical field
The utility model belongs to jacking equipment safe operation device, and a kind of slip trailing type unbalance loading is controlled safety tongs bindiny mechanism.
Background technology
The speed limit anti-drop system of using on jacking equipment at present of being made up of velocity limiter and safety tongs, the effect that hypervelocity and falling accident take place in preventing the carrier operational process is remarkable, is at present than a kind of speed limit anti-drop system of advanced person.This system requirements keeps certain clearance between safety tongs voussoir and the guide rail in operational process.But, adopt between safety tongs pincers seat and the carrier in this system to be rigidly connected, when the unbalance loading swing appearred in carrier, the normal clearance that very easily changes between voussoir and the guide rail made safety tongs generation misoperation, and carrier is stuck and causes fault out of service.And the swing of the unbalance loading of carrier is inevitable often, and therefore, the mounting means of this safety tongs exists very big hidden danger, has influenced the practicality and the popularity rate of the speed limit anti-drop system of being made up of retarder and safety tongs widely.The influence of unbalance loading swing to safety tongs controlled and eliminated to the unbalance loading swing of the carrier that has its source in of this hidden danger how, is the key point of problem.
Summary of the invention
Because the swing of the unbalance loading of carrier makes the normal clearance of safety tongs be difficult to control, it is important to have its source in to adopt between safety tongs and the carrier and is rigidly connected.Therefore, the purpose of this utility model just provides another kind of connection mode, to control and to eliminate the harmful effect of carrier unbalance loading swing to safety tongs normal clearance.
The technical solution of the utility model can guarantee the realization of its purpose:
1. adopt the connection mode combination between safety tongs pincers seat and the carrier.Between safety tongs pincers seat and carrier, slide mechanism is set, makes the sliding block joint that is connected to become between the two.This slide mechanism is the dovetail furrow slide mechanism, is made up of last planker and following planker.Last planker is rigidly attached to the carrier bottom down, and following planker is rigidly attached on the safety tongs pincers seat.
2. the glade plane space between the last planker of dovetail furrow slide mechanism and the following planker is adjusted by panel and governing screw.
The utility model makes being connected by traditional being rigidly connected between safety tongs pincers seat and the carrier change into sliding block joint, this has just eliminated the harmful effect of the unbalance loading swing of carrier to safety tongs effectively: because the pincers seat is rigidly connected with being connected to of following planker, the pincers seat is being followed the slip of planker and is being moved when the unbalance loading swing appears in carrier.The horizontal displacement that occurs between pincers seats and the guide rail is controlled and is eliminated by the relative slippage of the planker up and down of dovetail furrow slide mechanism; On the other hand, lead at high-strength nylon under the shock damping action of boots, horizontal clearance between safety tongs voussoir and the guide rail is effectively controlled and keeps in the reasonable scope.
The utlity model has simple in structure, easy to manufacture, cheap, advantage such as safe and reliable, improved the safety of the speed limit anti-drop system of forming by velocity limiter and safety tongs, prevented effectively that carrier is stuck and fault out of service takes place, can improve the practicality and the popularity rate of this speed limit anti-drop system greatly.The utility model is applicable to the vertical lifting equipment of steel rope traction driving or chain-drive vertical lifting and lifting cross sliding type machinery, particularly large-scale heavy duty, as large stereo garage parking, the large-scale vertical lifting equipment of harbour and large-scale elevator etc.
Description of drawings
Fig. 1 is the utility model johning knot composition;
Fig. 2 is the utility model dovetail furrow slide mechanism block diagram;
Fig. 3 is the utility model pincers seat block diagram.
In the accompanying drawing, safety tongs pincers seats (1), carrier (2), last planker (3), following planker (4), panel (5), set screw (6) is led boots (7), guide rail (8).
The specific embodiment
With reference to accompanying drawing, adopt the connection mode combination between safety tongs pincers seats (1) and the carrier (2).Between safety tongs pincers seats (1) and carrier (2), slide mechanism is set, makes the sliding block joint that is connected between the two.This slide mechanism is the dovetail furrow slide mechanism, is made up of last planker (3) and following planker (4).Last planker is rigidly attached to the carrier bottom down, and following planker is rigidly attached on the safety tongs pincers seat.But this be rigidly connected bolt together or welding etc.Glade plane space between last planker and the following planker is adjusted by panel (5) and set screw (6).(kinematic accuracy of dovetail furrow slide mechanism is had relatively high expectations.) lead boots (7) by what high-strength nylon compacting formed, be connected with safety tongs pincers (1) by screw.
Claims (2)
1, a kind of slip trailing type unbalance loading is controlled safety tongs bindiny mechanism, adopt the connection mode combination between safety tongs pincers seats (1) and the carrier (2), it is characterized in that between safety tongs pincers seats (1) and carrier (2), slide mechanism being set, make the sliding block joint that is connected between the two; Described slide mechanism is the dovetail furrow slide mechanism, is made up of last planker (3) and following planker (4); Last planker (3) is rigidly attached to carrier (2) bottom down, and following planker (4) is rigidly attached on the safety tongs pincers seat.
2, according to the described slip trailing type of claim 1 unbalance loading control safety tongs bindiny mechanism, it is characterized in that the glade plane space between planker (3) and the following planker (4) is adjusted by panel (5) and set screw (6).
