[0002] In the road traffic safety assurance system, guardrail emergency repair work is of paramount importance, and its efficiency and quality directly affect road driving safety. As the core equipment for performing guardrail emergency repair tasks, the guardrail emergency repair vehicle plays a crucial role in the smooth progress of the repair work by adjusting the lifting guide rails on the vehicle so that the pile driving and pulling components on the lifting guide rails can adapt to various working conditions.

[0003] Currently, the adjustment methods of the lifting guide rail adjustment mechanism of traditional guardrail repair vehicles are relatively simple. Some adjustment mechanisms can only achieve simple up-and-down lifting and left-and-right movement functions. This makes it difficult for the repair vehicle to accurately adjust the lifting guide rail to the appropriate position and angle when facing complex working conditions, such as roads with different slopes, narrow bends, or guardrails with special shapes. This results in low repair efficiency and may even prevent the completion of the repair task. Utility Model Content

[0004] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a lifting guide rail adjustment mechanism for guardrail repair vehicles, which can adjust the lifting guide rail in multiple positions.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a lifting guide rail adjustment mechanism for a guardrail repair vehicle, comprising:

[0006] A rotary seat, which is mounted on the body of the guardrail repair vehicle;

[0007] The slide is hinged to the rotary seat;

[0016] Preferably, the connecting frame includes a bottom beam, two side columns and a top beam. The bottom beam is located below the two sliding grooves. The two side columns are fixed to both sides of the two sliding grooves and are fixedly connected to the bottom beam. The top beam is located above the sliding grooves and its two ends are fixedly connected to the two side columns respectively.

[0017] Preferably, a wear-resistant plate is fixed to the inner side of the groove.

[0018] Preferably, two stiffening plates are fixed on the rotating bracket, and the two stiffening plates are respectively fixedly connected to two sliding grooves.

[0019] Preferably, the stiffener is inverted L-shaped, and the top of the stiffener is fastened to the groove.

[0020] Preferably, a nut seat is fixed on the slide groove, and a limiting bolt for abutting against the left and right guide rails is threaded onto the nut seat.

[0026] The beneficial effects of this utility model are as follows:

[0027] The slide block designed in this utility model can change its forward and backward tilt angle on the rotary seat under the drive of the front and rear adjusting cylinders, thereby changing the forward and backward tilt of the lifting guide rail.

[0037] 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.

[0038] Example 1:

[0039] like Figures 1 to 6 As shown, Embodiment 1 of this utility model provides an adjustment mechanism for the lifting guide rail 7 of a guardrail repair vehicle, used in conventional road guardrail repair operations. Its main function is to drive the lifting guide rail 7 to move relative to the body of the guardrail repair vehicle. A slewing seat 1 is provided on the body of the guardrail repair vehicle. The slewing seat 1 is the top connecting seat of the slewing mechanism. Since this utility model does not design the slewing mechanism on the body of the guardrail repair vehicle, the composition of the slewing mechanism of the slewing seat 1 on the body of the guardrail repair vehicle will not be described in detail.

[0040] Combination Figure 1 , Figure 4 and Figure 5 It is known that three lugs are fixed on the rotary seat 1, and the slide 2 is hinged to two of the symmetrical lugs, which gives the slide 2 the freedom to tilt back and forth on the rotary seat 1. In order to control the tilt angle of the slide 2, the cylinder body of the front-to-back adjusting cylinder 3 is hinged to the other lug, and the piston rod of the front-to-back adjusting cylinder 3 is hinged to the slide 2. Thus, when it is necessary to change the tilt angle of the lifting guide rail 7, the front-to-back adjusting cylinder 3 is activated, and the extension and retraction of its piston rod causes the slide 2 to adjust the tilt angle on the rotary seat 1. For example, when repairing a road guardrail with a certain slope, by extending the front-to-back adjusting cylinder 3, the slide 2 is tilted forward at a certain angle, which in turn causes the lifting guide rail 7 to tilt forward, so as to better adapt to the slope and enable the lifting guide rail 7 to operate the guardrail more accurately.

[0041] The left and right guide rails 4 include two parallel rectangular tubes 41 and two end plates 42 welded to both ends of the rectangular tubes 41. The end plates 42 and the rectangular tubes 41 form a frame structure, which is structurally stable. The two rectangular tubes 41 are slidably mounted on the slide block 2. A connector 43 is also welded between the two rectangular tubes 41. The connector 43 can be a rectangular profile or a sheet metal. The piston rod of the left and right adjusting cylinder 5 is hinged to the slide block 2, and the cylinder body is hinged to the connector 43 of the left and right guide rails 4. When it is necessary to adjust the left and right position of the lifting guide rail 7 on the guardrail repair vehicle body, the left and right adjusting cylinder 5 is activated, and its piston rod extends and retracts, pushing the left and right guide rails 4 to slide left and right in the slide block 2. For example, when repairing the guardrail at the edge of the road, the left and right adjusting cylinder 5 slides the left and right guide rails 4 towards the edge of the road, thereby moving the lifting guide rail 7 to a suitable position to facilitate the repair work on the edge guardrail.

[0042] like Figure 2 As shown, the lifting guide rail 7 is hinged to the right end of the left and right guide rails 4, the cylinder body of the luffing cylinder 6 is hinged to the left and right guide rails 4, and the piston rod is hinged to the lifting guide rail 7. When it is necessary to change the left and right tilt angle of the lifting guide rail 7, the luffing cylinder 6 is activated, and the extension and retraction of its piston rod drives the lifting guide rail 7 to rotate on the left and right guide rails 4. For example, when repairing guardrails with special angles, the left and right tilt angle of the lifting guide rail 7 can be adjusted by the luffing cylinder 6 to match the angle of the guardrail, thereby improving the efficiency and accuracy of the repair operation.

[0043] With the above settings, this utility model can achieve multi-directional adjustment of the lifting guide rail 7, significantly improving the adaptability of the guardrail repair vehicle to complex working conditions.

[0044] Example 2:

[0045] like Figure 5 and Figure 6 As shown, based on Embodiment 1, the present invention designs the specific structure of the slide block 2 as follows. The slide block 2 includes two parallel slide grooves 22 and two parallel rotating supports 21. The two rotating supports 21 are located on the lower sides of both ends of the slide grooves 22 and are welded to the slide grooves 22. The bottoms of the two rotating supports 21 are hinged to the ear plates at the left and right ends of the top of the rotary seat 1, which gives the slide grooves 22 the freedom to rotate around the hinge axis.

[0046] To further increase the structural strength of the slide block 2, a stiffening plate 211 is welded onto the rotating support 21. The stiffening plate 211 is inverted L-shaped, and its right-angled top portion fastens to the top of the slide groove 22, securing the slide groove 22. The stiffening plate 211 is also welded to the slide groove 22, which further increases the connection strength between the slide groove 22 and the rotating support 21.

[0047] Because the overall height of the slide groove 22 and the rotating bracket 21 is relatively low, connecting the front and rear adjusting cylinder 3 to the slide block 2 is inconvenient. Therefore, a connecting frame 23 is fixed on the slide groove 22, and the connecting frame 23 is hinged to the piston rod of the front and rear adjusting cylinder 3. Figure 5 As shown, the connecting frame 23 includes a bottom beam 231, two side columns 232, and a top beam 233. The bottom beam 231 is located below the two sliding grooves 22 and is welded to them. The two side columns 232 have slots that fit the sliding grooves 22 and are welded to them respectively. The side columns 232 are also welded to the bottom beam 231. The top beam 233 is parallel to the bottom beam 231 and is welded to the two side columns 232. Since the side columns 232 are higher than the sliding grooves 22, the piston rod of the front and rear adjusting cylinder 3 can be hinged to the side columns 232, allowing the front and rear adjusting cylinder 3 to function better.

[0048] Example 3:

[0049] Based on Embodiments 1 and 2, this invention adds a wear-resistant plate 221 fixed inside the slide groove 22. The wear-resistant plate 221 is made of nylon, which significantly reduces friction when the left and right guide rails 4 slide within the slide groove 22, extending the service life of both the slide groove 22 and the left and right guide rails 4. To prevent accidental sliding of the left and right guide rails 4 within the slide groove 22 during shutdown and transportation, this invention adds multiple nut seats 222 fixed to the two slide grooves 22. Each nut seat 222 is threaded with a limit bolt, which can be used to tighten the left and right guide rails 4 before equipment transportation, preventing accidental sliding and improving safety.

[0050] The specific operating procedure is as follows. When the guardrail repair vehicle encounters complex working conditions, such as when repairing guardrails on narrow roads with many curves, the tilt angle of the slide block 2 is first finely adjusted using the front and rear adjusting cylinders 3, so that the lifting guide rail 7 can adapt to the slope changes of the curve. Because the connecting frame 23 raises the hinge position of the piston rod of the front and rear adjusting cylinders 3, the piston rod requires less effort when driving the slide block 2 to tilt forward and backward, and the angle of the slide block 2 can be adjusted more quickly and accurately.

[0051] Next, the left and right adjusting cylinders 5 drive the left and right guide rails 4 to slide left and right in the slide grooves 22 of the slide block 2, adjusting the lifting guide rail 7 to a suitable position close to the inner guardrail of the curve. Finally, according to the specific angle of the guardrail at the curve, the variable amplitude cylinder 6 drives the lifting guide rail 7 to rotate on the left and right guide rails 4, precisely adjusting the left and right tilt of the lifting guide rail 7, so that the lifting guide rail 7 can smoothly carry out emergency repair work on the guardrail at the curve, fully demonstrating the good adaptability of this solution to complex working conditions.

[0052] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
