Abstract
The utility model provides a limit for height crossbeam of highway limit for height frame, including crossbeam body, insurance chaining, crossbeam body both ends are equipped with the flange board of being connected with jacking equipment, are equipped with the chaining collecting vat on the crossbeam body of insurance chaining bottom. An inclined plate is arranged in the hanging chain collecting tank, the high end of the inclined plate is located at the bottom of the pin shaft, and the bottom end of the inclined plate inclines towards the center direction of the beam body. And an upright guide plate is arranged on the outer side edge of the hanging chain collecting tank. The utility model discloses set up chaining collecting vat and deflector on the crossbeam body, when the limit for height crossbeam rises, the insurance chaining can fall into the chaining collecting vat automatically, avoids appearing the flagging phenomenon of insurance chaining; the inclined plate is inclined inwards from the bottom of the pin shaft, so that falling safety hanging chains can sequentially enter the bottom of the hanging chain collecting groove. When the height-limiting beam descends, the safety hanging chains can be reversely lifted in sequence, the phenomenon that the safety hanging chains are wound and knotted can not occur, and the lifting operation of the height-limiting beam is more stable.
Description
Technical Field
The utility model relates to a traffic facilities technical field especially relates to a limit for height crossbeam of highway limit for height frame.
Background
The highway height-limiting frame also plays a role in preventing special vehicles needing normal passing while limiting the passing of large vehicles. Such as fire trucks, watering lorries, etc., are also affected by highway height restrictions. The height-limiting beams of most highway height-limiting frames are therefore configured as lifting height-limiting beams. The lifting height-limiting beam needs to be suspended by a safety sling chain so as to prevent the broken height-limiting beam from flying out, so that passersby are injured by crashing, vehicles are damaged, and the life and property safety of people is harmed. In actual use, the height-limiting beam is driven to lift by the lifting slide blocks on two sides, and the safety sling chain is only used as a safety device and does not bear the weight of the height-limiting beam. The safety suspension chain can be coiled or unbent along with the lifting of the height limiting beam. When the height-limiting beam rises to a high place, the safety hanging chain can droop to the bottom of the height-limiting beam, so that the safety hanging chain is neither attractive nor safe, and the problem of winding and knotting is also caused, so that the lifting of the height-limiting beam is influenced.
Disclosure of Invention
The utility model provides a technical problem provide a limit for height crossbeam of highway limit for height frame, this limit for height crossbeam has safe and reliable, convenient to use, simple structure's advantage.
In order to solve the technical problem, the utility model adopts the following technical scheme: the utility model provides a limit for height crossbeam of highway limit for height frame which characterized in that: the safety hanging chain comprises a beam body and two safety hanging chains arranged on two sides above the beam body by pin shafts, wherein flange plates connected with lifting equipment are arranged at two ends of the beam body, and a hanging chain collecting tank is arranged on the beam body at the bottom of each safety hanging chain.
Furthermore, the outer side edge of the hanging chain collecting tank is close to the outer side of the bottom of the pin shaft, an inclined plate is arranged in the hanging chain collecting tank, the high end of the inclined plate is located at the bottom of the pin shaft, and the bottom end of the inclined plate inclines towards the center direction of the beam body.
Furthermore, the outer side edge of the hanging chain collecting tank is provided with an upright guide plate, the guide plate is close to the safety hanging chain, and when the beam body rises and the safety hanging chain drops, the safety hanging chain can slide to the bottom end of the inclined plate.
The height-limiting beam of the highway height-limiting frame is provided with the hanging chain collecting tank and the guide plate, when the height-limiting beam rises, the safety hanging chain can automatically fall into the hanging chain collecting tank, and the phenomenon that the safety hanging chain sags and shakes is avoided; the inclined plate is inwards inclined from the bottom of the pin shaft, so that the falling safety hanging chains can slide to the bottom of the hanging chain collecting tank in a section-by-section sequential arrangement mode, when the height limiting beam descends, the safety hanging chains can be reversely lifted in a sequential mode, the phenomenon that the safety hanging chains are wound and knotted can not occur, and the lifting operation of the height limiting beam is more stable.

The corresponding part names in the figure are: 1, a beam body; 2, a pin shaft; 3, hanging a safety chain; 4, flange plates; 5 hanging a chain collecting tank; 6 an inclined plate; 7 a guide plate; 100 upright posts; 101 a top cross beam; 102 to lift the device.
Detailed Description
Please refer to fig. 1, the utility model provides a height-limiting beam of highway height-limiting frame, including crossbeam body 1, utilize round pin axle 2 to install in two insurance braced chains 3 of crossbeam body top both sides, crossbeam body both ends are equipped with the flange board 4 of being connected with jacking equipment, are equipped with the braced chain collecting vat 5 on the crossbeam body of insurance braced chain bottom. The outer side edge of the hanging chain collecting tank is close to the outer side of the bottom of the pin shaft, an inclined plate 6 is arranged in the hanging chain collecting tank, the high end of the inclined plate is located at the bottom of the pin shaft, and the bottom end of the inclined plate inclines towards the center direction of the beam body. The outer side edge of the hanging chain collecting tank is provided with an upright guide plate 7, the guide plate is close to the safety hanging chain, and when the beam body rises and the safety hanging chain drops, the safety hanging chain can slide to the bottom end of the inclined plate.
Referring to fig. 2, the height-limiting beam of the road height-limiting frame based on the structural design is installed in a door-shaped frame of the road height-limiting frame, flange plates 4 at two ends of a beam body are connected with lifting devices of upright columns 100 at two sides, the upper end of a safety hanging chain 3 is hung below a top beam 101, when the lifting devices of the upright columns at two sides drive the beam body 1 to ascend, a guide plate 7 guides the safety hanging chain 3 to slide inwards, the safety hanging chain can automatically fall into a hanging chain collecting tank, and the phenomenon that the safety hanging chain sags and shakes is avoided; the inclined plate 6 is inwards inclined from the bottom of the pin shaft, so that the safety hanging chains 3 falling down can slide to the bottom of the hanging chain collecting tank in a section-by-section sequential arrangement mode, when the cross beam body 1 descends, the safety hanging chains 3 can be lifted in a reverse section-by-section sequential mode, the phenomenon that the safety hanging chains 3 are wound and knotted can not occur, and the lifting operation of the height limiting cross beam is more stable.
