[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The present invention is further described in detail below in conjunction with the embodiments.

[0025] like Figure 1-7 As shown, a specific embodiment of a collision-resistant and riot-proof lifting column provided by the utility model:

[0026] A collision-resistant and riot-proof lifting column, comprising a lifting column body 1, a lifting drive mechanism 2 and an embedded tube 3, wherein the embedded tube 3 has a cavity with an open top, and the wall thickness of the embedded tube 3 is 5 mm, which can withstand more impact energy and significantly improve the collision resistance. The lifting column body 1 is movably arranged in the cavity of the embedded tube 3, the length of the lifting column body 1 is 850 mm, and the wall thickness is 12 mm. The lifting drive mechanism 2 is used to drive the lifting column body 1 to move up and down in the cavity of the embedded tube 3. The moving mechanism 2 is a prior art and can be a hydraulic cylinder, an electric cylinder or other equipment. A load-bearing plate 4 is provided on the top of the embedded tube 3. An anti-collision nylon sleeve 5 is provided on the inner wall of the upper end of the embedded tube 3. The upper end surface of the anti-collision nylon sleeve 5 is flush with the upper end surface of the load-bearing plate 4. A flange ring 6 is installed on the load-bearing plate 4 by a number of bolts. The flange ring 6 is used to limit the anti-collision nylon sleeve 5 in the embedded tube 3; a wire storage and maintenance box 7 is provided on the upper outer wall of the embedded tube 3. The wire storage and maintenance box 7 is used to store oil circuits or circuits, etc.

[0027] The outer diameter of the lifting column body 1 is equal to the inner diameter of the anti-collision nylon sleeve 5. The anti-collision nylon sleeve 5 is sleeved on the outer periphery of the lifting column body 1. A plurality of anti-collision beams 8 are evenly arranged on the outer wall of the lower end of the lifting column body 1. The anti-collision beams 8 are U-shaped.

[0028] During the use of the anti-collision and riot-proof lifting column of this embodiment, the principle of anti-collision ability is analyzed as follows: when a vehicle hits the lifting column body 1 and loses the ability to continue driving, the lifting roadblock remains in a blocking state, and the internal structures of the lifting column cooperate with each other, and the lifting column body 1 is the first to receive the impact. During the collision, the lifting column body 1 and the anti-collision beam jointly bear the collision energy; during the collision, the anti-collision nylon sleeve 5 close to the lifting column body 1 absorbs part of the energy generated by the collision, and finally the lifting column body 1, the anti-collision beam 8 and the anti-collision nylon sleeve 5 absorb the remaining collision energy and transfer it to the underground close to the embedded tube 3; the anti-collision beam 8 is a U-shaped structure, and the anti-collision performance of the horizontal and vertical bidirectional force-bearing area is improved by 150%. Compared with the single-piece anti-collision beam 8, it is not easy to deform after being subjected to external force.

[0029] In addition, in this embodiment, the load-bearing plate 4, the flange ring 6 and the embedded tube 3 jointly bear the load and force, and can pass heavy special wheels to roll over.

[0030] In order to improve the connection strength between the load-bearing plate 4 and the embedded tube 3 , a plurality of triangular ribs 9 are evenly distributed between the bottom surface of the load-bearing plate 4 and the outer wall of the embedded tube 3 .

[0031] Secondly, the device can be further optimized, such as Figure 4 As shown, a mounting groove 10 is provided on the load-bearing plate 4 , the upper end of the anti-collision nylon sleeve 5 is a small-diameter end 11 , the flange ring 6 is sleeved on the small-diameter end 11 , and the flange ring 6 is installed on the mounting groove 10 .

[0032] like Figure 5 As shown, a top cover 12 is provided at the top of the lifting column body 1 , the outer edge of the top cover 12 is a slope structure 13 , and the small diameter end of the anti-collision nylon sleeve 5 has a bell mouth structure 14 , which is adapted to the slope structure 13 on the outer edge of the top cover 12 .

[0033] After the lifting column body 1 descends to the ground, the inclined surface structure 13 on the outer edge of the top cover 12 and the bell-mouth structure 14 at the end of the anti-collision nylon sleeve 5 form a close seal to prevent dust from entering through the gap when vehicles pass by, causing the mechanical activity margin to be stuck and affecting smooth lifting.

[0034] A guide member is provided to guide the lifting process of the lifting column body 1, specifically, Figure 6 and Figure 7 As shown, a plurality of guide rods 15 are fixed between the bottom of the embedded tube 3 and the lower end of the anti-collision nylon sleeve 5, and a plurality of guide sliders 16 are arranged on the outer wall of the lower end of the lifting column body 1. The guide sliders 16 are arranged one by one with the guide rods 15, and the guide sliders 16 are provided with slide grooves 17. The guide rods 15 are inserted into the slide grooves 17 of the corresponding guide sliders 16. When the lifting column body 1 moves upward, the guide sliders 16 slide along the guide rods 15, thereby forming a guide for the lifting column body 1 when it moves.

[0035] It should be noted that, in this article, terms such as "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0036] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
