Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to a traffic guardrail with traffic signs. Background Art

[0002] When the existing highway traffic guardrail is installed as a whole, the height of both sides cannot be effectively adjusted. The overall size of the guardrail is fixed, so when it is installed on uneven ground, it is easy for one end to be fixed and the other end to be not fixed. This makes the strength during isolation not very high and is prone to deformation and damage.

[0003] A highway traffic guardrail disclosed in application number 202223276879.1 achieves the purpose of adjusting the overall height position by adjusting the support foot plates at the lower sides of the two ends of the U-shaped guardrail frame.

[0004] However, in this patent, the structure at the upper end is adjusted by the support foot plate set at the bottom of the structure, that is, the whole structure needs to be lifted up, which can be achieved by rotating the support foot plate, reducing the adjustment efficiency. While lifting the whole structure, the reserved gap in the structure at the connection between adjacent guardrails will also produce extrusion, causing the structures to collide with each other and limit the lifting height, that is, reducing the actual achievable adjustment height, thereby affecting the actual adjustment effect of the guardrail.

DETAILED DESCRIPTION

[0027] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0028] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0029] The adjustment structure of the existing guardrail 1 is generally located at the lower end of the guardrail 1, so the whole structure needs to be raised to achieve the adjustment by rotating the support foot plate. On the one hand, the adjustment efficiency is reduced. On the other hand, when the whole structure is raised, the reserved gap at the connection point of adjacent guardrails will also produce extrusion, causing the structures to collide with each other and limit the lifting height, that is, reducing the actual achievable adjustment height, thereby affecting the actual adjustment effect of the guardrail. Based on the problems of low adjustment efficiency and poor effect in the adjustment process of the support foot 4 of the existing guardrail 1, the present embodiment discloses a traffic guardrail with traffic signs, such as Figure 1-Figure 5 As shown, a guardrail 1 is provided. The guardrail 1 is U-shaped, and a middle beam 2 is installed horizontally from left to right on it to increase its horizontal load and enhance the strength of lateral force. A sign 3 for posting traffic signs is set between the middle beam 2 and the guardrail 1. The sign 3 is bonded with traffic signs, such as no passage. A support leg 4 is provided at the lower end of the guardrail 1 to compensate for the height difference of the road surface. The guardrail 1 can be rotated by using a middle cylinder 45 slidably installed on the straight rod 44 while the guardrail 1 remains stationary, thereby providing a torsional power for the sleeve 42 screwed with the screw 41. The screw 41 is extended or disengaged in the straight rod 44, thereby increasing or decreasing the height of the guardrail 1 relative to the support leg 4 as a whole, thereby achieving the purpose of adjustment.

[0030] like Figure 3 As shown, the support leg 4 is specifically provided with a screw 41 installed at the lower end of the guardrail 1 and sleeved therewith rigidly connected thereto, the screw 41 is externally threaded with a sleeve 42, and the lower end of the sleeve 42 is provided with a base 43 connected by a straight rod 44, the diameter of the straight rod 44 is larger than the diameter of the screw 41, and the straight rod 44 is connected to the sleeve 42 by a rolling bearing. The base 43 is rigidly connected to the straight rod 44, as shown in FIG. Figure 4 As shown, the bottom of the screw rod 41 is connected to a stopper placed inside the straight rod 44 to limit its single up and down movement mode, and a groove adapted to the up and down sliding of the stopper is opened inside the straight rod 44. By opening a groove 454 with a diameter larger than that of the screw rod 41 on the straight rod 44, the groove 454 provides a passage for the straight rod 44 to enter, thereby achieving the purpose of adjusting the extension length of the screw rod 41 in the sleeve 42. The middle cylinder 45 that establishes or releases the connection relationship with the sleeve 42 to adjust the length of the screw rod 41 in the sleeve 42 is slidably installed on the straight rod 44.

[0031] In order to realize that the middle tube 45 can be selectively connected with the sleeve 42, as shown in FIG. Figure 2As shown, the middle cylinder 45 is provided with a cylinder body 451 and a diffuser plate 452 installed on the side wall of the cylinder body 451. The top and bottom surfaces of the diffuser plate 452 are provided with a plurality of striped grooves to increase the contact friction with the foot and enhance the force effect. The cylinder body 451 is provided with an inner groove 453 having a diameter larger than the straight rod 44, and an alignment block 455 is installed in the inner groove 453. The straight rod 44 is provided with an alignment groove 456 adapted to the alignment block 455 for guiding the sliding track when the cylinder body 451 slides. When the road surface is uneven and the connection cannot be completed normally, the foot pushes against the bottom surface of the diffuser plate 452 to lift it upward, and the alignment block 455 of the diffuser plate 452 slides upward along the alignment groove 456 until it is connected with the bottom of the sleeve 42. At this time, the setting height of the cylinder body 451 is less than the distance between the sleeve 42 and the base 43. The upper and lower ends of the cylinder 451 are respectively provided with a connecting piece 46 for connecting with the sleeve 42 or the base 43. The connecting piece 46 includes a circumferentially arranged positive hole 461 on the upper end of the cylinder 451, which is adapted to the convex column provided on the bottom surface of the sleeve 42. A convex strip 462 is convexly provided on the bottom surface of the cylinder 451, which is adapted to the cross groove provided on the top surface of the base 43. The sleeve 42 is connected to the cylinder 451 by the adaptation of the convex column provided on the sleeve 42 and the positive hole 461. At this time, the dispersion plate is pushed by the foot, hand or other tools to drive the sleeve 42 to rotate, and the screw rod 41 is restricted from following the rotation under the action of the limiting block, so that when the sleeve 42 rotates, the screw rod 41 will produce an upward or downward movement in the straight rod 44, forming a height adjustment of the guardrail 1.

[0032] A plurality of connecting grooves 5 arranged from top to bottom are installed on the single side wall of the guardrail 1. The connecting groove 5 is installed on the guardrail 1 by bolts. The connecting groove 5 is hollow inside and a through groove 6 is opened on the side wall. A connecting column 7 is set on the side wall of the guardrail 1 opposite to the installation surface of the connecting groove 5 and is inserted into the connecting groove 5 to connect the two guardrails 1. The connecting column 7 includes a mounting pad connected to the guardrail 1, and a connecting plate 71 is set on the mounting pad to complement and form a docking with the through groove 6. The front end of the connecting plate 71 is set with an inner connecting column 72 that is nested in the connecting groove 5 and connected with the connecting groove 5. An inner groove is opened on the guardrail 1 at the installation position of the connecting column 7. The mounting pad is embedded in the inner groove to support the inner groove structure. The length of the connecting plate 71 extending outside the inner groove is equal to the length of the through groove 6. The connecting grooves 5 are separated and independently set. Therefore, when a single connecting groove 5 is damaged, it can be disassembled for repair or replacement, and the remaining other connecting grooves 5 can still achieve the connection function.
