The stainless steel semi-automatic lifting bollard with chain intercepts all vehicles, and the two lifting columns are directly equipped with chains and can be removed freely
The wall thickness of the lifting column can be 3mm thick, the smallest diameter can be 133mm-168mm, made of 304 stainless steel, the embedded depth is 0850mm,
Lifting columns, also known as lifting columns or anti-collision road piles, isolation piles, etc., are widely used in urban traffic, military and national important offices and surrounding areas, pedestrian streets, highway toll stations, airports, schools, banks, large clubs, and parking Field and many other fields. By restricting passing vehicles, the traffic order and the safety of major facilities and places are effectively guaranteed.
In the prior art, the adjustment of the lifting column is very troublesome, time-consuming and laborious, which usually delays the entry and exit of emergency vehicles. Therefore, we propose a new type of chain lifting column to solve the above problems. Technical implementation elements: The present invention provides a new type of chain lifting column, which has the advantage of convenient adjustment, thereby solving the problems raised in the background art. In order to achieve the purpose of convenient adjustment, the present invention provides the following technical solutions: a new type of chain lifting column includes an inner tube, an outer tube, a spring and a zipper, and the inner tube can be pulled out or retracted by external force.
The inner cylinder includes an inner cylinder bottom plate, an inner cylinder flange, a spring catch lock column and a lock head fixing column. The inner cylinder bottom plate is welded with a middle hole at the bottom of the inner cylinder for guiding. The inner cylinder flange is welded to the inner cylinder. Above, the welding points are respectively on the spring catch lock column and the lock head fixing column. The outer barrel includes the edge of the first outer lid, the edge of the second outer lid, the base of the outer barrel, the screw sleeve and the core sleeve. The outer barrel is buried in the ground to prevent the accessories of the inner barrel from being mixed into the concrete. The first outer lid The edge is welded to the surface of the outer barrel, the edge of the second outer lid is welded to the edge of the first outer lid, the bottom of the outer barrel is arranged at the bottom of the outer barrel to prevent concrete from entering the inner barrel, and the screw sleeve is welded to the edge of the first outer lid , Weld the lock core sleeve with the base of the outer barrel to fix it.
As a preferred technical solution of the present invention, an upper cover is provided at the upper end of the outer cylinder, and the upper cover is fixed on the edge of the first outer cylinder cover by a screw sleeve and an M10 screw. The outer cylinder is also equipped with a guide flange, a spring fixing seat, a spring column, a second lock column, a guide column and a first lock column, so that the guide column is fixed in the middle, and the inner cylinder cannot be locked. Use four screws to fix the inner cylinder bottom plate Pierce the spring fixing seat into the guide column and place it inside the outer cylinder, and weld the column to the spring fixing seat by welding with the spring column. The welding method is linear welding to pull the lock back. The second The lock post is used to twist the lock 45° before use. The first lock column and the upper cover are welded together to rotate the lock head. As a preferred technical solution of the present invention, three friction blocks are arranged inside the top of the outer cylinder, and the three friction blocks are fixed on the inside of the outer cylinder and the outer surface of the inner cylinder by rubbing with M6 screws. . As a preferred technical solution of the present invention, the top of the inner cylinder is provided with an inner upper cover and a handle, the handle is used to pull the inner cylinder to slide up and down, and the inner upper cover is welded to the top of the inner cylinder after the handle is fixed and installed.
As a preferred technical solution of the present invention, the inner barrel is provided with a lock barrel, a lock cover, a lock post and a spring, the lock barrel is welded to the lock cover, and the lock post is clamped therein. The middle groove is provided with M5 screws to prevent it from moving up and down. One side of the lock cover is welded to the lock pipe column, and the other side of the lock baffle is hooked together with the spring. As a preferred technical solution of the present invention, after the lock cylinder sleeve is welded to the outer cylinder base, the second lock cylinder is fixed by the lock cylinder sleeve, so that the second lock cylinder does not deflect. As a preferred technical solution of the present invention, snap rings are provided at both ends of the zipper, the snap ring at one end of the zipper is located inside the inner cylinder, and the snap ring is used at the other end of the zipper. Snap into the hole position of the side lifting column. As a preferred technical solution of the present invention, the zipper is used to pull up the zipper to stop pedestrians and vehicles. After placing the zipper.
