Description

Technical Field

[0001] This utility model belongs to the field of lifting column technology, specifically relating to a lifting column structure that can correct concentricity. Background Technology

[0002] Currently, most electric rising bollards on the market are installed using a pre-embedded method, with the bollard rising and falling inside the pre-embedded cylinder. However, due to construction errors, foundation settlement, or insecure fixing of the pre-embedded cylinder, the concentricity between the bollard and the pre-embedded cylinder is difficult to guarantee, resulting in the bollard tilting, shaking, or even scraping and wearing against the cylinder wall during the lifting process. After long-term use, this not only affects the appearance and sealing of the bollard but also increases the load on the drive system and reduces the lifespan of the equipment. Utility Model Content

[0003] The present invention aims to provide a lifting column structure that can correct concentricity, thereby solving the technical problem of difficulty in controlling the concentricity between the column body and the pre-embedded cylinder after the existing lifting column is installed.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A concentricity-correcting lifting column structure includes a pre-embedded cylinder, a column, and a mechanism. The top of the pre-embedded cylinder is provided with a cylinder top cover, and the top of the column is provided with a column top cover. Both the column and the mechanism are set inside the pre-embedded cylinder. The column is connected to the mechanism, and the column can extend upward through the cylinder top cover under the push of the mechanism.

[0006] A base plate is welded to the bottom of the embedded cylinder, and a mounting plate is fixed to the bottom of the mechanism. The four corners of the mounting plate are connected to the base plate by a set of adjustable lifting connectors.

[0007] Furthermore, the adjustable lifting connector includes a lifting screw and a fixing screw. A through hole and a first screw hole are provided on the mounting plate, and a second screw hole is provided on the base plate. The second screw hole is arranged vertically and vertically corresponding to the through hole. The lifting screw is threaded into the first screw hole, and the lower end of the lifting screw abuts against the base plate. The fixing screw passes through the through hole, and the lower part of the fixing bolt is threaded into the second screw hole.

[0008] Furthermore, an elastic gasket is provided between the mounting plate and the base plate.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: Through the innovative design of the adjustable lifting connector, this utility model achieves precise concentricity correction after the lifting bollard is installed, effectively solving the problems of lifting vibration, wear and overload of the drive system caused by the misalignment of the pre-embedded cylinder and the bollard in the traditional structure; its four-corner independent adjustment mechanism combined with the phased fixing strategy is not only easy to operate and highly accurate in adjustment, but also ensures the stability of long-term use, significantly extending the service life of the lifting bollard and reducing maintenance costs, making it particularly suitable for high-precision security and traffic management scenarios with frequent start and stop.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] The present invention will be further described in detail below with reference to the embodiments.

[0018] like Figure 1-5 As shown, here is a specific embodiment 1 of the concentricity-correctable lifting column structure provided by this utility model:

[0019] A concentricity-correcting lifting column structure includes a pre-embedded cylinder 1, a column 2, and a mechanism 3. The top of the pre-embedded cylinder 1 is provided with a cylinder top cover 4, and the top of the column 2 is provided with a column top cover 5. The column 2 and the mechanism 3 are both set inside the pre-embedded cylinder 1. The column 2 is connected to the mechanism 3, and the column 2 can extend upward through the cylinder top cover 4 under the push of the mechanism 3.

[0020] The bottom of the pre-embedded cylinder 1 is welded with a base plate 6, and the bottom of the mechanism 3 is fixed with an mounting plate 7. The four corners of the mounting plate 7 are connected to the base plate 6 by a set of adjustable lifting connectors 8.

[0021] The adjustable lifting connector 8 includes a lifting screw 9 and a fixing screw 10. A through hole 11 and a first screw hole 12 are provided on the mounting plate 7, and a second screw hole 13 is provided on the base plate 6. The second screw hole 13 is arranged vertically corresponding to the through hole 11. The lifting screw 9 is threaded into the first screw hole 12, and the lower end of the lifting screw 9 abuts against the base plate 6. The fixing screw 10 is inserted into the through hole 11, and the lower part of the fixing screw is threaded into the second screw hole 13.

[0022] The specific concentricity correction and adjustment process of the adjustable concentricity lifting column structure in this embodiment is as follows:

[0023] (1) Fix the mechanism 3 to the inner bottom plate 6 of the pre-embedded cylinder 1 through the mounting plate 7. At this time, the fixing screw 10 passes through the through hole 11 of the mounting plate 7 and is screwed into the second screw hole 13 of the bottom plate 6, but is not tightened, so that the mounting plate 7 can move slightly; the lifting screw 9 is pre-screwed into the first screw hole 12 of the mounting plate 7, and the lower end is in slight contact with the surface of the bottom plate 6.

[0024] (2) Observe the gap between the top cover 5 of the column and the top cover 4 of the cylinder to determine the tilt direction. If the left side is too low, tighten the left lifting screw 9 clockwise so that its lower end presses against the bottom plate 6 and lifts the left side of the mounting plate 7 upward. If the right side is too low, adjust the right lifting screw 9 to achieve unilateral lifting.

[0025] By independently adjusting the four corner lifting screws 9, the top of the movement 3 is made parallel to the top cover of the pre-embedded cylinder 1 (initially concentric).

[0026] (3) After completing the concentricity correction, tighten all the fixing screws 10 in diagonal order (to avoid uneven force on the mounting plate 7 and deformation); then check whether the lifting screws 9 are still in close contact with the base plate 6.

[0027] In addition, an elastic gasket 14 can be added between the mounting plate 7 and the base plate 6 to compensate for minor deformations caused by thermal expansion and contraction.
