[0002] Temporary height restrictions on roads refer to the use of height restriction facilities to limit vehicle height at specific times and sections of roads to ensure the safety of infrastructure such as roads, bridges, and tunnels, as well as passing vehicles and pedestrians. The following are some common scenarios for temporary height restrictions on roads: Road maintenance: When renovating a large area of ​​roads, repairing potholes, and other construction projects, there will be various construction equipment and materials piled up in the construction area, and the road conditions are complex. Setting temporary height restrictions can prevent over-height vehicles from entering the construction area, avoid colliding with construction equipment, and damage the newly built road surface, while ensuring the safety of construction workers.

[0003] Underground pipeline construction: When laying or repairing underground cables, water pipes, gas pipelines, etc., it is necessary to dig up the road surface. At this time, setting a temporary height limit can prevent overheight vehicles from causing damage to the excavation equipment and laid pipelines in the construction area due to body shaking or improper operation, thereby preventing safety accidents.

[0004] Bridge structure inspection: Regularly inspect the structure of the bridge to evaluate its bearing capacity, stability, etc. During the inspection, some inspection equipment may be installed on the bridge, occupying part of the bridge deck space. Temporary height restrictions can prevent overheight vehicles from scratching the inspection equipment, affecting the normal inspection work, and avoid accidental damage to the bridge structure.

[0005] Sports events: Marathons, cycling races and other sports events sometimes use city roads as race tracks. To ensure the safety and order of the events, temporary height restrictions are set on the roads around the race tracks to restrict the entry of large vehicles and avoid causing interference and danger to the contestants.

[0054] By adopting the above technical solution, when the height limiting cross arm 8 is unfolded, the pulling plate 73 is flipped along with the height limiting cross arm 8, and the pulling plate 73 pushes the protrusion 74 of the second locking member 72 upward, and when the protrusion 74 slides to the through groove 77, the protrusion 74 is clamped and fixed with the through groove 77; in this way, before the locking bolt 75 is locked and fixed, there is no need to manually maintain the position of the height limiting cross arm 8, and the locking bolt 75 can be well locked and installed.

[0055] In this embodiment, the arm kit 71 is fixed on the flange mounting plate 78; the flange mounting plate 78 is fixed on the top of the rectangular tube 12; the rectangular tube 12 is arranged inside the inner tube 11 and fixed by bolts, and the upper end of the rectangular tube 12 is higher than the upper end of the inner tube 11;

[0056] Please refer to the attached Figures 3 to 9 A diamond-shaped locking disc 15 is fixed inside the lower end of the rectangular cylinder 12; a first traction rope 13 is fixed to the diamond-shaped locking disc 15; the first traction rope 13 passes upward from the gap between the inner cylinder 11 and the outer cylinder 1 after passing through the first rotating wheel 14, and is fixed from the upper end of the outer cylinder 1. A second traction rope 16 is also fixed to the diamond-shaped locking disc 15; the second traction rope 16 passes upward from the gap between the rectangular cylinder 12 and the inner cylinder 11, passes through the second rotating wheel 18, and is fixed to the driving frame 19; the driving frame 19 is fixedly connected to the cylinder rod of the oil cylinder 4; the second rotating wheel 18 is fixed to one side of the upper end of the inner cylinder 11 through a bracket.

[0057] By adopting the above technical scheme, when the height of the first height limiting rod bracket 100 is adjusted, the cylinder rod of the oil cylinder 4 contracts, and the driving frame 19 is pulled downward following the cylinder rod of the oil cylinder, and the second traction rope 16 is pulled downward under the traction of the driving frame 19, so that the second traction rope 16 has an upward pulling force on the diamond locking disk 15, and the diamond locking disk 15 simultaneously pulls one end of the first traction rope 13 upward; since the other end of the first traction rope 13 is fixed to the outside of the upper end of the outer cylinder 1; therefore, under the traction of the first traction rope 13 and the second traction rope 16, the first rotating wheel 14 together with the inner cylinder 11 and the rectangular cylinder 12 are lifted upward at the same time, and the rectangular cylinder 12 lifts the height limiting cross arm 8 installed on the support arm locking assembly 7, thereby realizing the height adjustment of the first height limiting rod bracket 100.

[0058] Please refer to the attached Figure 1 and Figure 2 In this embodiment, the height limiting cross arm 8 in the first height limiting rod bracket 100 is docked with the height limiting cross arm 8 in the second height limiting rod bracket 200, and is connected by a sleeve and fixed by bolts.

[0059] It is assembled in a symmetrical installation manner, with a simple structure and easy deployment.

[0060] In this embodiment, the upper end of the oil cylinder 4 is arranged between two oil cylinder brackets 5, and a first locking member 6 is also provided between the two oil cylinder brackets 5. The first locking member 6 is used to fix the position of the oil cylinder bracket 5, and the first locking member 6 is also fixed to the oil cylinder bracket 5.

[0061] The provision of the first locking member 6 and the oil cylinder bracket 5 enables the oil cylinder 4 to be fixed.

[0062] The working principle is: when deploying the height limit frame, firstly, the height limit cross arm 8 is unfolded outwardly, so that the height limit cross arm 8 and the outer tube 1 are arranged at 90 degrees; when the height limit cross arm 8 is unfolded, the pull plate 73 fixed to the height limit cross arm 8 pushes the protrusion 74 on the second locking member 72 outwardly until the protrusion 74 is stuck in the through groove 77, and then the locking bolt 75 is locked and fixed with the locking screw hole 76, thereby realizing the locking and fixing of the second locking member 72 and the pull plate 73; at the same time, the unfolding of the height limit cross arm 8 is also completed;

[0063] Align the base plate 31 and make it perpendicular to the movable connecting piece 2, and tighten it with bolts; then, clamp and fix the locking plate 33 with the clamping column 34 on the outside of the movable connecting piece 2, so as to achieve the support of the installation base 3 on the outer cylinder 1 and the movable connecting piece 2; use anchor bolts to pass through the slots around the base plate 31 and install it on the ground, so as to achieve the fixation of the height limit frame.

[0064] When adjusting the height, the cylinder rod of the oil cylinder 4 contracts, and the driving frame 19 is pulled downward following the cylinder rod of the oil cylinder. The second traction rope 16 is pulled downward under the traction of the driving frame 19, so that the second traction rope 16 has an upward pulling force on the diamond locking plate 15, and the diamond locking plate 15 simultaneously pulls one end of the first traction rope 13 upward; since the other end of the first traction rope 13 is fixed to the outside of the upper end of the outer cylinder 1; therefore, under the traction of the first traction rope 13 and the second traction rope 16, the first rotating wheel 14 together with the inner cylinder 11 and the rectangular cylinder 12 are lifted upward at the same time, and the rectangular cylinder 12 lifts the height limiting cross arm 8 installed on the support arm locking assembly 7, thereby realizing the height adjustment of the first height limiting rod bracket 100 or the second height limiting rod bracket 200.

[0065] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
