Technical Field

[0001] The utility model relates to the technical field of traffic facilities, in particular to a fast-responsive traffic isolation fence. Background Technique

[0002] The traffic isolation fence, also known as a separation railing or traffic separation railing, is a structure set within the road range, mainly used to separate vehicle flows, standardize traffic order, and protect the safety of pedestrians and vehicles. It has been widely used in traffic facilities on urban roads and highways in our country. Most of the current traffic isolation fences are fixed, unable to be adjusted, inconvenient to operate, and greatly increase the workload of traffic police officers. Content of the Utility Model

[0003] The purpose of the utility model is to provide a fast-responsive traffic isolation fence to solve the problems put forward in the above background technique that most traffic isolation fences are fixed, unable to be adjusted, inconvenient to operate, and greatly increase the workload of traffic police officers.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] The fast-responsive traffic isolation fence includes isolation side frames arranged on both sides and two parallel isolation crossbars arranged between two groups of isolation side frames. Synchronously working height-adjusting cylinders are installed on the outer side walls of the two groups of isolation side frames, and a height-limiting cross frame for height limitation is also installed between the two groups of isolation side frames;

[0006] Lifting sliding seats are installed at both ends of the isolation crossbar, a connecting cross frame is vertically installed at the top of the outer wall of the piston rod of the height-adjusting cylinder, and the connecting cross frame is inserted and matched with the outer wall of the lifting sliding seat;

[0007] Inner sliding grooves that are adapted to the cross-sectional size of the lifting sliding seat and are in sliding fit are opened on the inner side walls of the isolation side frames, and outer sliding grooves that are adapted to the cross-sectional size of the connecting cross frame and are in sliding fit are opened on the outer side walls of the isolation side frames.

[0008] Preferably, a fixed base in the shape of a frustum of a pyramid is installed at the bottom of the isolation side frame.

[0030] Quick response type traffic isolation fence, such as Figures 1-3As shown in the figure, it includes isolation side frames 10 arranged on both sides and two parallel isolation cross bars 20 arranged between two groups of isolation side frames 10. Height adjustment cylinders 30 that work synchronously are installed on the outer side walls of the two groups of isolation side frames 10. An overheight limiting cross frame 40 for limiting height is also installed between the two groups of isolation side frames 10; lifting sliders 20 are installed at both ends of the isolation cross bar 20. A connecting cross frame 33 is vertically installed at the top of the outer wall of the piston rod 31 of the height adjustment cylinder 30. The connecting cross frame 33 is inserted and matched with the outer wall of the lifting slider 20; an inner sliding groove 12 that is adapted to the cross-sectional size of the lifting slider 20 and is in sliding fit is opened on the inner side wall of the isolation side frame 10. An outer sliding groove 13 that is adapted to the cross-sectional size of the connecting cross frame 33 and is in sliding fit is opened on the outer side wall of the isolation side frame 10. By the lifting sliders 21 installed at both ends of the isolation cross bar 20 and slidingly matched with the inner sliding groove 12 on the inner side wall of the isolation side frame 10, the isolation cross bar 20 can slide smoothly up and down along the isolation side frame 10, realizing flexible adjustment of the height of the isolation fence. Through the setting of the height adjustment cylinder 30, the height adjustment process of the isolation fence is automated, improving work efficiency. The connecting cross frame 33 vertically installed at the top of the outer wall of the piston rod 31 of the cylinder is inserted and matched with the outer wall of the lifting slider 20, ensuring that the telescopic movement of the cylinder piston rod can accurately drive the isolation cross bar 20 to rise and fall. The setting of the overheight limiting cross frame 40 plays a role in limiting height, preventing overheight vehicles from straying into the isolation area, thus ensuring the safety and effectiveness of the traffic isolation fence.

[0031] Furthermore, a fixed base 11 in the shape of a trapezoid is installed at the bottom of the isolation side frame 10 to ensure that the fixed base 11 stably supports the isolation side frame 10.

[0032] Specifically, fixing screw holes 14 for fixing the height adjustment cylinder 30 are opened on the outer wall of each group of isolation side frames 10. Fixed side ears 32 that are symmetrically arranged on both sides of the height adjustment cylinder 30 and have the same number and corresponding positions as the fixing screw holes 14 are provided. The fixed side ears 32 are threadedly connected to the outer wall of the isolation side frame 10 through fixing screws passing through the fixing screw holes 14, facilitating installation or disassembly and ensuring that the height adjustment cylinder 30 is firmly fixed on the isolation side frame 10.

[0033] Among them, several uniformly spaced and parallel railings 22 are installed between the two groups of isolation cross bars 20 to improve stability.

[0034] In addition, a flashing sticker 23 is arranged on the outer wall of the railing 22. The flashing sticker 23 is made of an LED flash strip and is powered by an external power supply. It is ensured that the flashing sticker 23 is flatly attached to the railing 22 and can work normally, emitting a flashing light to increase the warning effect.

[0035] Working principle of this quick-response traffic isolation barrier: When traffic intervention is required, the traffic police personnel start the height-adjusting cylinder 30 according to actual needs, and its piston rod 31 expands and contracts. As the piston rod 31 expands and contracts, the connecting cross-frame 33 will drive the lifting sliding seat 21 to slide downward in the inner sliding groove 12, thereby isolating traffic. When the traffic isolation barrier is no longer needed, the height-adjusting cylinder 30 can be closed to raise the isolation cross-bar 20 to the lowest position.

[0036] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
