Description

Technical Field

[0001] This utility model relates to the field of guardrail auxiliary materials, specifically to a quick replacement and installation device for guardrails. Background Technology

[0002] Guardrails prevent vehicles from going out of control or off the road in the event of a traffic accident. By absorbing collision energy, they reduce the impact force on vehicles and minimize damage to vehicles and passengers.

[0003] During daily use, the guardrail may be damaged by collisions, requiring replacement with new ones. When replacing, it is necessary to lift the guardrail by hand and install it by aligning it with the bolt holes of the mounting post. However, since the guardrail is usually 3-4 meters long and made of metal, it is quite heavy, making manual handling and installation very troublesome, time-consuming and laborious. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a quick replacement and installation device for guardrail panels.

[0005] This utility model is achieved through the following technical solution:

[0006] A quick-change and installation device for guardrail panels includes a movable support frame and a backrest frame vertically arranged at the center of its upper part. A support plate for supporting the guardrail panel is provided on one side of the backrest frame. A sliding component that moves up and down is provided at the lower part of the support plate. An elliptical rotator with height adjustment is provided at the bottom of the sliding component.

[0007] Further optionally, the sliding assembly includes sliding rods fixed to both sides of the lower part of the support plate, the sliding rods being slidably connected to a sliding sleeve mounted on the movable support frame.

[0008] Alternatively, the elliptical rotator includes an elliptical axis facing the bottom of the sliding rod, with a rotating shaft mounted on the lower part of the elliptical axis. Both ends of the rotating shaft are rotatably connected to a support fixed on the movable support frame, and one end of the rotating shaft extends to the outer end of the support and is connected and fixed to the pressure rod.

[0009] Alternatively, a roller is mounted at the bottom of the sliding rod to contact the elliptical axis of rotation.

[0010] Alternatively, the sliding sleeve can be connected and fixed to the movable support frame via a connecting bracket.

[0011] Alternatively, a support tray may be movably positioned on top of a movable support frame, the top of which has a slot.

[0012] Compared with existing technologies, the advantages of this utility model are: the utility model has a simple structure and is easy to operate. The two upper sliding rods are adjusted synchronously through the elliptical rotator, thereby achieving stable height adjustment of the support plate. This makes it easier to find the bolt holes of the installation post when installing the guardrail. The installation process does not require personnel to carry and adjust the center, saving time and effort and greatly improving the efficiency of installation. Attached Figure Description

[0015] In the diagram: 1. Movable support frame; 2. Backrest frame; 3. Support plate; 4. Sliding rod; 5. Sliding sleeve; 501. Connecting frame; 6. Rolling wheel; 7. Elliptical rotating shaft; 8. Rotating shaft; 9. Support seat; 10. Pressure bar; 11. Guardrail plate. Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0017] like Figure 1 As shown, a quick-change and installation device for guardrail panels includes a movable support frame 1 and a backrest frame 2 vertically arranged at the center of its upper part. The backrest frame 2 serves to support the guardrail panel 11. A support plate 3 for supporting the guardrail panel 11 is provided on one side of the backrest frame 2. A sliding component that moves up and down is provided at the lower part of the support plate 3. An elliptical rotator for height adjustment is provided at the bottom of the sliding component.

[0018] like Figure 2 As shown, the sliding assembly includes sliding rods 4 fixed on both sides of the lower part of the support plate 3. The sliding rods 4 are slidably connected to the sliding sleeves 5 installed on the movable support frame 1. The sliding rods 4 move up and down in the sliding sleeves 5 to achieve stable height adjustment of the support plate 3.

[0019] like Figure 2 As shown, the elliptical rotator includes an elliptical rotating shaft 7 facing the bottom of the sliding rod 4. A rotating shaft 8 is installed in the lower part of the elliptical rotating shaft 7. Both ends of the rotating shaft 8 are rotatably connected to the support base 9 fixed on the movable support frame 1. One end of the rotating shaft 8 extends to the outer end of the support base 9 and is connected and fixed to the pressure rod 10. The rotation angle of the elliptical rotating shaft 7 is adjusted by pressing the pressure rod 10, thereby adjusting the height of the upper sliding rod 4.

[0020] like Figure 2 As shown, a rolling wheel 6 is installed at the bottom of the sliding rod 4, which contacts the elliptical axis 7. Rolling friction is achieved through the rolling wheel 6, which avoids dry friction between the elliptical axis 7 and the sliding rod 4 and improves the stability of the rotation of the elliptical axis 7.

[0021] like Figure 1 As shown, the sliding sleeve 5 is connected and fixed to the movable support frame 1 through the connecting bracket 501.

[0022] like Figure 1 As shown, the support plate 3 is movably placed on top of the movable support frame 1. The top of the support plate 3 has a slot, which prevents the guardrail plate 11 from falling off the support plate 3.

[0023] The implementation principle of the quick replacement and installation device for guardrail panels in this application embodiment is as follows:

[0024] When replacing guardrail panel 11, this utility model places the new guardrail panel 11 into the slot of the support plate 3, and then pushes the movable support frame 1 to move it to the side of the corresponding mounting post. The operating lever 10 drives the elliptical rotating shaft 7 on the rotating shaft 8 to rotate. By rotating the elliptical rotating shaft 7 and changing the axis distance, it pushes the sliding rod 4 to move up and down, thereby realizing the height adjustment of the upper support plate 3 and the guardrail panel 11. This makes it easier for the guardrail panel 11 to find the bolt holes of the mounting post. The installation process does not require personnel to carry and adjust the center, saving time and effort and greatly improving the efficiency of installation.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
