[0001] This utility model relates to the field of traffic guardrail technology, and in particular provides a traffic guardrail post and a traffic guardrail, which is especially suitable for situations such as traffic diversion in municipal engineering, major events, emergency rescue, phased construction, temporary control of intersection closures, and temporary lane switching at security checkpoints. Background Technology

[0002] Currently, the guardrails commonly used in engineering are mainly divided into two types based on their movement: fixed and mobile. Fixed guardrails have a relatively fixed application range, cannot be reused, and are not flexible enough; mobile guardrails are prone to movement if not properly controlled, have poor stability, and pose certain safety hazards.

[0003] Therefore, developing a new type of traffic guardrail that combines stability and flexibility has become an urgent problem to be solved. Utility Model Content

[0004] In view of this, the present invention provides a traffic guardrail post and a traffic guardrail to solve the problems existing in the current traffic guardrail.

[0005] This utility model provides a traffic guardrail post, comprising: a post body, a post base, and a lifting structure. The post base is fixedly connected to the bottom of the post body. The post body and post base form a bottom-opening receiving cavity. A crossbar sleeve is provided on the side wall of the post body. The lifting structure is fixedly installed within the receiving cavity. The lifting structure includes a driving device, a threaded rod, an upper limiting cylinder, a lower lifting cylinder, and a bottom moving structure. The driving device is fixed to the top of the receiving cavity. The threaded rod is vertically arranged and its top end is connected to the driving device for rotation under the drive of the driving device. The upper limiting cylinder is fixed... The upper limiting cylinder is installed inside the receiving cavity and located outside the threaded rod. The inner wall of the upper limiting cylinder is provided with a limiting protrusion. A top plate nut is fixedly installed on the top of the lower lifting cylinder. The side wall of the lower lifting cylinder is provided with a longitudinal groove. The lower lifting cylinder is fitted inside the upper limiting cylinder. The top plate nut is connected to the threaded rod. The longitudinal groove is correspondingly fitted to the limiting protrusion. The bottom moving structure includes a moving base plate and multiple rollers connected below the moving base plate. The moving base plate is fixedly connected to the bottom of the lower lifting cylinder. By driving the threaded rod to rotate, the rollers can support the column body and column base or hide them inside the receiving cavity.

[0006] Preferably, the column body and the column base are connected by bolts.

[0007] Further preferably, the driving device includes a rotary handle and a gear steering mechanism. The gear steering mechanism includes a first bevel gear, a second bevel gear, and a housing. The housing is fixed inside the receiving cavity. The first bevel gear and the second bevel gear are both mounted inside the housing via bearings and mesh with each other. The rotary handle is connected to the first bevel gear, and the second bevel gear is connected to the threaded rod. The side wall of the column body is provided with mounting holes corresponding to the rotary handle.

[0008] Preferably, the upper limiting cylinder is fixedly connected to the lower part of the housing.

[0009] In a further preferred embodiment, the inner wall of the upper limiting cylinder is provided with a plurality of limiting protrusions spaced apart along its circumference, and the side wall of the lower lifting cylinder is provided with a plurality of longitudinal grooves, the longitudinal grooves corresponding one-to-one with the limiting protrusions.

[0018] The present invention will be further described below with reference to specific embodiments.

[0019] like Figures 1 to 3 As shown, this utility model provides a traffic guardrail post, including: a post body 1, a post base 2, and a lifting structure 3. The post base 2 is fixedly connected to the bottom of the post body 1, forming the external structure of the traffic guardrail post. The interior of the post body 1 and the post base 2 forms a receiving cavity with an open bottom. A crossbar sleeve 11 is provided on the side wall of the post body 1 for connection to an intermediate protective structure. The lifting structure 3 is fixedly installed within the receiving cavity. The lifting structure 3 includes a driving device 31, a threaded rod 32, an upper limiting cylinder 33, a lower lifting cylinder 34, and a bottom moving structure 35. The driving device 31 is fixed to the top of the receiving cavity. The threaded rod 32 is vertically arranged and its top end is connected to the driving device 31 for rotation under the drive of the driving device 31. The limiting cylinder 33 is fixedly installed in the receiving cavity and located outside the threaded rod 32. The inner wall of the upper limiting cylinder 33 is provided with a limiting protrusion 331. A top plate nut 341 is fixedly installed on the top of the lower lifting cylinder 34. The side wall of the lower lifting cylinder 34 is provided with a longitudinal groove 342. The lower lifting cylinder 34 is fitted into the upper limiting cylinder 33. The top plate nut 341 is connected to the threaded rod 32. The longitudinal groove 342 is correspondingly fitted to the limiting protrusion 331. The bottom moving structure 35 includes a moving base plate 351 and a plurality of rollers 352 connected below the moving base plate 351. The moving base plate 351 is fixedly connected to the bottom of the lower lifting cylinder 34. By driving the threaded rod 32 to rotate, the rollers 352 can support the column body 1 and the column base 2 or hide them in the receiving cavity.

[0020] The traffic barrier post consists of two parts: an inner and an outer structure. The inner lifting structure, driven by a drive unit, controls the synchronous raising and lowering of the lower lifting cylinder and the bottom moving structure. When the lower lifting cylinder and the bottom moving structure descend to the point where the rollers support the outer structure (post body and post base), the rollers touch the ground, and the post base is suspended in the air. At this time, the traffic barrier post can be moved by external force, improving the flexibility of its use. When it moves to the designated position, the lower lifting cylinder and the bottom moving structure rise synchronously through the drive unit, hiding the rollers and bringing the post base to the ground, achieving a temporary fixing effect and improving the stability of the traffic barrier post. The principle of the lower lifting cylinder's raising and lowering is as follows: when the drive unit drives the threaded rod to rotate, the lower lifting cylinder cannot rotate due to the cooperation between the limiting protrusion and the longitudinal groove. Therefore, it can only rise and fall within the upper limiting cylinder along with the top plate nut.

[0021] As an improvement to the technical solution, the column body 1 and the column base 2 are connected by bolts.

[0022] The driving device can be an electric drive device (motor), as an improvement to the technical solution, such as... Figure 2 As shown, the drive device 31 includes a rotary handle 311 and a gear steering mechanism 312. The gear steering mechanism 312 includes a first bevel gear 3121, a second bevel gear 3122, and a housing 3123. The housing 3123 is fixed within the receiving cavity. The first bevel gear 3121 and the second bevel gear 3122 are both mounted within the housing 3123 via bearings and mesh with each other. The rotary handle 311 is connected to the first bevel gear 3121, and the second bevel gear 3122 is connected to the threaded rod 32. Figure 1 As shown, the side wall of the column body 1 is provided with mounting holes 12 corresponding to the rotating handle 311.

[0023] As an improvement to the technical solution, such as Figure 2 As shown, the upper limiting cylinder 33 is fixedly connected to the lower part of the housing 3123.

[0024] To ensure the stability of the lifting, as an improvement to the technical solution, the inner wall of the upper limiting cylinder 33 is provided with a plurality of limiting protrusions 331 at intervals along its circumference, and the side wall of the lower lifting cylinder 34 is provided with a plurality of longitudinal grooves 342, the longitudinal grooves 342 corresponding one-to-one with the limiting protrusions 331. Preferably, three limiting protrusions are evenly distributed along the circumference of the upper limiting cylinder.

[0025] To ensure the stability of movement, as an improvement to the technical solution, such as Figure 2 As shown, the movable base plate 351 is rectangular and its horizontal cross-sectional dimension is larger than that of the upper limiting cylinder 33. The distance between the rollers should be relatively large. In order to ensure the stability of the traffic guardrail column when it is fixed, the weight of the column base should be relatively large.

[0026] As an improvement to the technical solution, the roller 352 is a universal wheel, which can be installed under the movable base plate via bearings.

[0027] This utility model also provides a traffic guardrail, including: an intermediate protective structure and the above-mentioned traffic guardrail posts, wherein the traffic guardrail posts are connected to the intermediate protective structure through the crossbar sleeve 11.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
