Description

Technical Field

[0001] The utility model relates to the field of road facilities, and more specifically, to a road width limiting pier. Background Art

[0002] In order to prevent vehicles that are too wide from entering, some roads are equipped with width-limiting piers at the entrance of the road. In the existing technology, most width-limiting piers are formed by pouring concrete directly on the ground, which makes the width-limiting piers directly fixed to the ground.

[0003] When encountering an emergency, such as a fire, the presence of width-limiting piers prevents rescue vehicles from passing through in time, which will affect the rescue.

[0004] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

DETAILED DESCRIPTION

[0020] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0021] Road width limit pier, such as Figure 1 and Figure 4As shown, it includes a base 1 fixed on the ground and a blocking column 2 detachably connected to the base 1. The base 1 is directly fixed to the ground and the top surface of the base 1 is flush with the ground. A weight-reducing cavity 3 is provided in the blocking column 2, and an inner groove 4 is provided in the base 1. A plurality of reinforcing rods 5 for resisting the inner wall of the weight-reducing cavity 3 are slidably connected in the inner groove 4. A positioning pin 6 for limiting the sliding of the reinforcing rod 5 is provided on the base 1. In case of emergency, people can remove the blocking column 2 from the base 1. The setting of the weight-reducing cavity 3 makes the weight of the blocking column 2 lower, so that people can move it more easily. The retaining column 2 is moved, and then the restriction of the positioning pin 6 on the reinforcing rod 5 is released, so that the reinforcing rod 5 slides into the inner groove 4, so that the reinforcing rod 5 no longer protrudes above the ground, so that the emergency rescue vehicle can pass through this position in time. After the emergency is relieved, people can slide the reinforcing rod 5 out of the inner groove 4, and then use the positioning pin 6 to limit the reinforcing rod 5 so that the reinforcing rod 5 cannot slide back into the inner groove 4, and then reinstall the retaining column 2 on the base 1. The setting of the reinforcing rod 5 can better provide support for the retaining column 2, so that the road width limit pier can effectively prevent vehicles that are too wide from passing.

[0022] like Figure 2 and Figure 3As shown, a pull ring 7 is rotatably connected to the reinforcing rod 5, and a groove 8 for accommodating the pull ring 7 is opened on the base 1. When the pull ring 7 is accommodated in the groove 8, there is a gap between the pull ring 7 and the side wall of the groove 8 that can be inserted with a finger. When it is necessary to take the reinforcing rod 5 out of the inner groove 4, people can apply force to the pull ring 7 so that the reinforcing rod 5 can be better pulled out from the inner groove 4. The setting of the pull ring 7 provides people with a better force point to pull out the reinforcing rod 5. The pull ring 7 is rotatably connected to the reinforcing rod 5. One end of the pull ring 7 is provided so that when it is not in use, it can be rotated and fit into the inner wall of the groove 8, so that when the reinforcing rod 5 is stored in the inner groove 4, the pull ring 7 is not easy to protrude on the ground, so that the pull ring 7 will not affect the passage of the emergency rescue vehicle. A sliding groove 9 is provided on one side of the groove 8, and the positioning pin 6 slides in the sliding groove 9. A limiting groove 10 for the positioning pin 6 to be embedded is provided on the reinforcing rod 5. When the reinforcing rod 5 needs to be stored in the inner groove 4, people can slide the positioning pin 6 along the sliding groove 9. The groove 9 slides, causing the end of the positioning pin 6 to come out of the limiting groove 10, thereby releasing the limiting effect of the positioning pin 6 on the reinforcing rod 5, so that the reinforcing rod 5 can slide into the inner groove 4. The reinforcing rod 5 is cylindrical, and a long groove 11 is opened on the inner peripheral wall of the inner groove 4. The outer peripheral wall of the reinforcing rod 5 is provided with a protrusion 12 sliding in the long groove 11. Specifically, the reinforcing rod 5 is made of hollow round steel, and the reinforcing rod 5 with a cylindrical cross-section has good bending resistance, which makes the reinforcing rod 5 better provide support for the blocking column 2 When a vehicle hits the barrier column 2, the reinforcing rod 5 is not easy to bend. The reinforcing rod 5 made of a hollow round tube can better ensure the strength of the reinforcing rod 5 while also better reducing the weight of the reinforcing rod 5, so that people can save effort when pulling the reinforcing rod 5. When people pull the pull ring 7 to slide the reinforcing rod 5, the protrusion 12 slides along the inner wall of the long groove 11, so that the reinforcing rod 5 will not rotate in the inner groove 4, so that when the reinforcing rod 5 slides into place, the limit groove 10 can align with the positioning pin 6.

[0023] like Figure 4 and Figure 5As shown, a mounting block 13 is provided on the inner wall of the weight reduction cavity 3, a first embedding groove 14 and a second embedding groove 15 to prevent the mounting block 13 from falling out are provided on the base 1, and the second embedding groove 15 is provided on the side wall of the first embedding groove 14. The first embedding groove 14 and the second embedding groove 15 are both communicated with the surface of the base 1 and the opening of the first embedding groove 14 is larger than the opening of the second embedding groove 15. The mounting block 13 can pass through the first embedding groove 14 and enter the second embedding groove 15. There are several mounting blocks 13, and the several mounting blocks 13 are distributed in a ring array with the center of the blocking column 2 as the axis. The mounting block 13 includes a card block provided at one end thereof away from the blocking column 2, and the projected area of ​​the card block is equal to the opening area of ​​the first embedding groove 14. In the process of reinstalling the blocking column 2 back to the base 1, people We need to align the mounting block 13 with the first embedding groove 14, and after embedding the mounting block 13 in the first embedding groove 14, rotate the blocking column 2 so that the mounting block 13 slides into the second embedding groove 15 along the inner wall of the first embedding groove 14, so that the mounting block 13 conflicts with the inner wall of the second embedding groove 15, thereby completing the limit of the blocking column 2 on the base 1. A crash pad is provided on the outer wall of the blocking column 2, and a reflective warning strip is posted on the crash pad. The crash pad is made of rubber material, which has a good shock-absorbing effect and can reduce the damage caused by the vehicle colliding with the width-limiting pier. The reflective warning strip is set. When the ambient light is insufficient, the vehicle's light can be reflected by the reflective warning strip to remind the driver to pay attention to the width-limiting pier and reduce the possibility of accidents caused by vehicles colliding with the width-limiting pier.
