Description

Technical Field

[0001] This utility model relates to the field of guardrail installation technology, specifically a calibration device for guardrail installation. Background Technology

[0002] During the installation of guardrails, calibration devices are used to ensure the verticality, horizontality, and connection accuracy between the various components. This allows the guardrails to distribute the force evenly when subjected to external impacts, preventing excessive localized stress and damage, thus effectively fulfilling their protective function and ensuring the safety of people and property.

[0003] A positioning device for guardrail installation, disclosed in patent publication number CN222558295U, includes a first mounting block and an infrared laser light. In use, the first support platform is first placed at the starting point of the guardrail arrangement. To arrange and position multiple guardrails in an orderly manner, a second support platform is placed at the ending point. To facilitate the placement of the second support platform at a suitable angle, an infrared laser light is installed on one side of the first support platform via the first mounting block. The vertical beam generated by the infrared laser light ensures that the laser beam's illumination point coincides with the positioning block on the surface of the second mounting block, reducing placement errors. The first and second support platforms are connected by a positioning wide rope. A servo motor is controlled to rotate forward and backward via a switch panel. The servo motor's drive shaft drives a connected take-up roller to rotate synchronously. Under the action of the take-up roller, the positioning wide rope is straightened, and the guardrail to be installed is brought into contact with the surface of the positioning wide rope.

[0004] The aforementioned device uses a wide rope to position the guardrail during installation. However, in actual operation, the wide rope is easily affected by wind and sways, thus interfering with the accurate positioning of the guardrail. To address these issues, a calibration device for guardrail installation is proposed. Utility Model Content

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.

[0026] Please see Figures 1-4 In this embodiment, a calibration device for guardrail installation includes several sets of base plates 11 and guardrails 12 installed on the top of the base plates 11. A positioning rod 13 is fixedly connected to one side of the guardrail 12. A fixing component for fixing another set of positioning rods 13 is provided at the bottom of one set of base plates 11.

[0027] The fixing assembly includes a mounting plate 15 and a locking block 19. The mounting plate 15 is fixedly connected to the bottom of the positioning rod 13, and the locking block 19 is fixedly connected to the bottom of the mounting plate 15. The top of the base plate 11 is rotatably connected to a rotating disk 14. The top of the rotating disk 14 is provided with a slot 20 for engaging the locking block 19. The top of the rotating disk 14 is provided with a positioning element for fixing the mounting plate 15.

[0028] The top of the base plate 11 is provided with a fixing member for positioning the rotation of the rotating disk 14, and the bottom of the base plate 11 is provided with a mounting member.

[0029] The positioning component includes fixing holes 18 and mounting holes 16. Several sets of fixing holes 18 are formed on the rotating disk 14. Several sets of mounting holes 16 corresponding to the fixing holes 18 are formed on the mounting plate 15. Mounting bolts 17 are threaded into the mounting holes 16. The mounting bolts 17 are threaded into the fixing holes 18. The mounting plate 15 fits against the rotating disk 14. The mounting bolts 17 are inserted into the mounting holes 16 and fixing holes 18 and tightened to complete the installation, thereby fixing the positioning rod 13.

[0030] The fixing component includes a positioning hole 24, which is located on the top of the rotating disk 14. A positioning bolt 23 is threaded into the positioning hole 24. The top of the base plate 11 has several sets of limiting holes 25 for connecting with the positioning bolt 23. When the rotating disk 14 rotates to a specified angle, the positioning bolt 23 is inserted into the positioning hole 24 and the limiting hole 25 and tightened for fixation. This can fix the rotation of the rotating disk 14 and prevent the guardrail 12 from shaking.

[0031] The mounting components include several sets of brackets 27 and fixing bolts 28.

The pointer 22 is fixedly connected to one side of the rotating disk 14. The rotating disk 14 drives the pointer 22 to rotate, and the pointer 22 slides on the angle indicator dial 21. When it slides to the specified angle, it is convenient for the staff to make precise adjustments to the rotating disk 14.

[0033] The top of the base plate 11 has a through hole 26, and the rotating disk 14 is rotatably connected in the through hole 26. By setting the through hole 26, the rotating disk 14 can be rotated easily, so that the connection angle between the two sets of base plates 11 can be adjusted.

[0034] The working principle of this utility model is as follows: When assembling the guardrail 12, one set of base plates 11 is placed on one side of another set of base plates 11. The positioning bolt 23 is removed using an external tool. The rotating disk 14 is rotated, and the rotating disk 14 drives the pointer 22 to rotate. The pointer 22 slides on the angle indicator disk 21. When it slides to the specified angle, the positioning bolt 23 is inserted into the positioning hole 24 and the limiting hole 25 and tightened to fix it. Then, the locking block 19 at the bottom of the positioning rod 13 is inserted into the locking groove 20, so that the mounting plate 15 is in contact with the rotating disk 14. The mounting bolt 17 is inserted into the mounting hole 16 and the fixing hole 18 and tightened to complete the installation. Then, the fixing bolt 28 is fixed to the ground to prevent the guardrail 12 from shaking. The installation is completed. This can avoid the guardrail 12 from being affected by wind during installation and can also facilitate the adjustment and installation of different angles between the two sets of base plates 11.
