Abstract

The utility model discloses a height-limited portal frame capable of being lifted and fallen. The height-limited portal frame capable of being lifted and fallen comprises vertical columns or a group of vertical columns arranged on two sides of a road and a top beam which is arranged on the top portions of the vertical columns. A lifting beam is suspended below the top beam. Due to the fact that the lifting beam is suspended below the top beam of the height-limited portal frame, vehicles passing the road can b limited flexibly through adjustment of the height of the lifting beam, when traffic is more in daytime, the lifting beam is fallen to ban large vehicles to pass, and urban traffic congestion caused by the large vehicles is avoided. When traffic is less in the evening, the lifting beam is lifted to allow the large vehicles to pass, convenience is brought for transportation. According to the height-limited portal frame capable of being lifted and fallen, convenience is brought for residents going out, at the same time, urban roads are reasonably used, the lifting beam is fixedly controlled by a lifting mechanism fixed on the top beam, lifting and falling can be completed through remote control of operators on the ground, and operation is easy and convenient and labor-saving.

Description

A kind of liftable height-limiting gantry

Technical field

The utility model relates to the road traffic facility field, is specifically related to a kind of liftable height-limiting gantry.

Background technology

China is populous nation, and the city then is the population collection place in a city, and for the ease of city people's trip, improve the urban traffic blocking present situation, the subsidiary road in city forbids that oversize vehicle such as lorry is current daytime usually.The city can produce very big influence to the quick and safety of city resident trip because oversize vehicle is is frequently come in and gone out.In order to limit passing through of oversize vehicle, often in the entrance of some city subsidiary roads or urban road high surely height-limiting gantry is set, the mandatory lorry turnover city of forbidding.But the special location resident trip at night of some restricted driving is less, oversize vehicle is not only convenient and swift but also can bring influence to resident's trip hardly by this highway section in this period, but because the existence of the height-limiting gantry of the level altitude at this type of crossing, oversize vehicle needs to detour at night too, the trouble of not only having given daily conveyer belt has also limited the purposes of road.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of liftable height-limiting gantry, the different periods in different highway sections can be by regulating the height of spacing cross-arm, the vehicle class in the passing highway section of restricted driving rationally utilizes urban road when making things convenient for resident trip flexibly.

The utility model is achieved through the following technical solutions:

A kind of liftable height-limiting gantry comprises the sky beam that lays respectively between the single of road both sides or one group of column and the two heel post tops, and the beam below was hung with the lifting beam in described day.

The further improvement project of the utility model is, the hook that described lifting back end is provided be fixed on the hook that described day hoist on the beam be provided with and be connected.

The utility model further improvement project is, vertical fixing has guide rail on the described single column or on the connecting rod that is provided with between one group of column.

The utility model further improvement project is, fixes limited bit platform respectively on the column concordant with described guide rail two ends, and the junction of described spacing platform and described column is provided with ribs.

The utility model further improvement project is that described spacing platform stretches out 30cm to described column inboard at least.

The utility model further improvement project is, the two ends of described lifting beam are provided with roller, and described roller cooperates slip with described guide rail.

The utility model further improvement project is on the outer wall of described lifting beam and roller correspondence position beam to be arranged fixedly.

The utility model further improvement project is that the two ends of described lifting beam are respectively equipped with and the safe drag-line of fixedlying connected with the heel post top.

The utility model further improvement project is to fix limited high sign board on the described lifting beam.

The utility model compared with prior art has the following advantages:

One, the utility model suspension lifting beam under the sky of road height-limiting gantry beam, can be by regulating the lifting depth of beam vehicle of the passing road of restricted driving flexibly, when visitors flowrate is many by day, puts down the lifting beam and forbid passing through of oversize vehicle by force, avoid it that urban traffic is caused and block up.When night, the road visitors flowrate was rare, rise the lifting beam again and allow oversize vehicle to pass through, it is convenient to bring to transportation.When making things convenient for resident trip, the utility model rationally utilized urban road.

Two, lifting beam of the present utility model is by being fixed on the fixing control of hoist on day beam, and operating personnel just can finish lifting at ground remote control, and are easy and simple to handle laborsaving.

Description of drawings

Fig. 1 faces structural representation for the utility model.

Fig. 2 is A place enlarged diagram among Fig. 1.

The specific embodiment

A kind of liftable height-limiting gantry as illustrated in fig. 1 and 2 comprises the sky beam 2 between the column 1 that lays respectively at the road both sides and column 1 top, and beam 2 belows were hung with lifting beam 3 in described day.Lifting beam 3 is connected with the hook 41 that is fixed on the described day hoist 4 on the beam 2 by the hook 31 on top, and vertical fixing has guide rail 5 on the described column 1.The two ends of lifting beam 3 are provided with roller 32 and cooperate slip with guide rail 5.Hoist 4 is by remote control control, and the lifting beam in guide rail 5 lifting of sliding, is fixed limited bit flag board 9 by the pulling force of hook 41 on the lifting beam 3, be used for reminding the current lifting beam 3 of vehicular traffic apart from the height on ground,

Still as illustrated in fig. 1 and 2, fix limited bit platform 6 respectively on the column concordant with guide rail 5 two ends, spacing platform 6 is provided with ribs 7 with the junction of column 1.On the outer wall of lifting beam 3 and roller 32 correspondence positions beam 33 is arranged fixedly, in lifting beam 3 lifting process, can cushion the collision of lifting beam 3 and spacing platform 6.

As shown in Figure 1, the two ends of lifting beam 3 are respectively equipped with and the safe drag-line 8 of fixedlying connected with the heel post top, have increased the safety of this device, have avoided the hawser generation fracture of hoist 4 to cause lifting beam 3 to fall the loss that personnel and property are caused in the bottom surface.Wherein spacing platform 6 stretches out 30cm to described column 1 inboard at least, even the hawser of hoist 4 and safe drag-line 8 all disconnect, spacing platform 6 still can be caught the lifting beam 3 of tenesmus, the safety that further improves whole device.
