Description

Technical Field

[0001] The utility model relates to the technical field of municipal protection fences, in particular to a protection fence for municipal engineering. Background Art

[0002] Municipal guardrails are an important part of urban road traffic facilities, and their setting specifications are of great significance to ensure the safety of pedestrians and vehicles. The height of municipal guardrails is generally between 1.2 meters and 1.5 meters. Such a height can not only play a protective role, but also will not bring a sense of oppression to pedestrians. The existing guardrails are mainly composed of three parts: a base, a crossbar, and a column. There are vertical poles between the crossbars, but the current municipal protective guardrails have some defects when in use. Since the municipal guardrails are used to isolate urban roads, motor vehicle lanes, non-motor vehicle lanes, and pedestrian passages, it is inevitable that vehicles and pedestrians will collide with the guardrails. In particular, some vehicles deviate during driving and sometimes contact the guardrails with a small force. At this time, friction will occur between the guardrail and the vehicle. Small-force collisions and contacts often occur. Although the guardrail will not be directly knocked over and the people on the vehicle will not be in danger, it will scratch the vehicle paint and the paint on the surface of the guardrail. Generally, the cost of repainting a vehicle ranges from hundreds to thousands of yuan, which will still bring a lot of economic losses.

[0003] It is even more common for pedestrians to come into contact with guardrails. Some pedestrians will also bump into municipal guardrails, which can cause serious damage to the body. Therefore, in response to the above problems, we have made improvements to the municipal guardrails. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a guardrail for municipal engineering, which solves the problems raised in the above-mentioned background technology.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: a guardrail for municipal engineering, including a base, a lower crossbar, and an upper crossbar, the base is plugged with a guardrail post, both sides of the guardrail post are installed with a plug-in tube, the two ends of the lower crossbar and the upper crossbar are respectively inserted into the inner cavity of the plug-in tube, the upper crossbar is installed with two groups of buffer mechanisms, and the two groups of buffer mechanisms are respectively located on both sides of the lower crossbar.

[0006] The buffer mechanism consists of an upper mounting plate, a connecting plate, a lower connecting plate, a connecting column and a movable plate. The upper mounting plate is mounted on the upper surface of the lower cross bar by bolts. The upper mounting plate and the lower connecting plate are fixedly connected by the connecting plate. A plurality of movable grooves are opened on one side of the movable plate. A spring is fixedly connected to one end of the inner cavity of the movable groove. A plurality of connecting columns are installed in the inner cavity of the lower connecting plate and the upper mounting plate by bolts. The other ends of the plurality of connecting columns are all sleeved into the inner cavity of the movable groove and connected with one end of the spring. A protective sponge is fixedly mounted on the outer side of the movable plate.

[0007] Preferably, an isolation rod is fixedly connected between the lower cross bar and the upper cross bar.

[0008] Preferably, the other end of the lower connecting plate is fixedly connected to a U-shaped supporting plate, and the U-shaped supporting plate is sleeved onto the surface of the isolation rod, and matching screw holes are provided on the U-shaped supporting plate and the isolation rod.

[0009] Preferably, the guardrail posts, lower crossbar, isolation rod, upper crossbar, upper mounting plate, lower connecting plate, and movable plate are all made of stainless steel.

[0010] Preferably, the isolation rod and the protective sponge are covered with reflective stickers.

[0011] The utility model provides a protective fence for municipal engineering, which has the following beneficial effects:

[0012] The municipal engineering guardrail is designed with a buffer mechanism, and the upper mounting plate is installed by bolts, which is convenient for disassembly. The two ends of the lower cross bar and the upper cross bar are inserted into the inner cavity of the plug-in tube on the guardrail column, the bottom end of the guardrail column is inserted into the inner cavity of the base, one end of the connecting column is inserted into the upper mounting plate and the inner cavity of the lower connecting plate, and the connecting column is fixed with bolts, and then the upper mounting plate is placed on the surface of the upper cross bar, so that the U-shaped support plate covers the isolation rod, and then the upper mounting plate is fixed with bolts to complete the assembly. The operation is convenient, and both maintenance and replacement are convenient. When pedestrians or vehicles have a small impact contact with the guardrail, when the human body or vehicle contacts the protective sponge, the protective sponge itself is relatively soft, so at this time, neither the personnel nor the vehicle surface will be worn. At the same time, due to the extrusion of the movable plate, the spring will be compressed and moved to the side of the original collision body to achieve buffering and avoidance, thereby avoiding vehicles or pedestrians from contacting the municipal guardrail with a slight impact. Compared with traditional municipal guardrails, it is safer, reduces the probability of losses caused by some slight impacts, and avoids some economic and physical injuries.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Example 1: Reference Figure 1-Figure 6 The utility model provides a guardrail for municipal engineering, comprising a base 1, a lower crossbar 3, and an upper crossbar 5. A guardrail column 2 is plugged into the base 1, and plug-in tubes 6 are installed on both sides of the guardrail column 2. The two ends of the lower crossbar 3 and the upper crossbar 5 are respectively inserted into the inner cavity of the plug-in tube 6. The upper crossbar 5 is installed with two groups of buffer mechanisms, and the two groups of buffer mechanisms are respectively located on both sides of the lower crossbar 3.

[0022] The buffer mechanism consists of an upper mounting plate 9, a connecting plate 8, a lower connecting plate 15, a connecting column 10 and a movable plate 12. The upper mounting plate 9 is installed on the upper surface of the lower cross bar 3 by bolts. The upper mounting plate 9 and the lower connecting plate 15 are fixedly connected by the connecting plate 8. A plurality of movable grooves 14 are opened on one side of the movable plate 12. A spring 11 is fixedly connected to one end of the inner cavity of the movable groove 14. A plurality of connecting columns 10 are installed in the inner cavity of the lower connecting plate 15 and the upper mounting plate 9 by bolts. The other ends of the plurality of connecting columns 10 are all sleeved into the inner cavity of the movable groove 14 and connected with one end of the spring 11. A protective sponge 13 is fixedly installed on the outer side of the movable plate 12.

[0023] Through the design of the buffer mechanism, the upper mounting plate 9 is installed by bolts, which is convenient for disassembly. The lower cross bar 3 and the upper cross bar 5 are inserted into the inner cavity of the plug-in tube 6 on the guardrail column 2, and then the bottom end of the guardrail column 2 is inserted into the inner cavity of the base 1, and one end of the connecting column 10 is inserted into the inner cavity of the upper mounting plate 9 and the lower connecting plate 15. The connecting column 10 is fixed with bolts, and then the upper mounting plate 9 is placed on the surface of the upper cross bar 5, so that the U-shaped support plate 7 covers the isolation rod 4, and then the upper mounting plate 9 is fixed with bolts to complete the assembly.

[0024] When a pedestrian or a vehicle comes into contact with the guardrail with a small force, when the human body or the vehicle comes into contact with the protective sponge 13, the protective sponge 13 itself is relatively soft, so at this time, neither the surface of the person nor the vehicle will be worn. At the same time, the movable plate 12 is squeezed, and the spring 11 will be compressed to move to the side of the original collision body to achieve buffering and avoidance, thereby preventing vehicles or pedestrians from coming into contact with the municipal guardrail with a small force, which is safer and avoids some economic and physical injuries.

[0025] An isolation rod 4 is fixedly connected between the lower cross bar 3 and the upper cross bar 5 .

[0026] The other end of the lower connecting plate 15 is fixedly connected to a U-shaped supporting plate 7, and the U-shaped supporting plate 7 is sleeved onto the surface of the isolation rod 4. Both the U-shaped supporting plate 7 and the isolation rod 4 are provided with matching screw holes. When the guardrail is installed in an area with strong winds, bolts can be used to pass through the screw holes on the U-shaped supporting plate 7 and the isolation rod 4 for fixing. Under normal circumstances, only four bolts on both sides need to be installed, and the U-shaped supporting plate 7 is in contact with the surface of the isolation rod 4. The two corresponding U-shaped supporting plates 7 form a closed loop to sleeve the isolation rod 4 in the middle, thereby improving the installation stability of the integrated buffer mechanism.

[0027] The guardrail posts 2, the lower crossbar 3, the isolation rod 4, the upper crossbar 5, the upper mounting plate 9, the lower connecting plate 15, and the movable plate 12 are all made of stainless steel and have a rust-proof function.

[0028] Reflective stickers are affixed to the surfaces of the isolation rod 4 and the protective sponge 13. Reflective stickers of different styles can be affixed as needed. Elastic rubber blocks are connected between the movable plate 12 and the connecting plate 8. The elastic rubber blocks can be deformed, which not only reinforces the movable plate 12, but also prevents the movable plate 12 from shaking repeatedly. The elastic rubber blocks are bonded to the movable plate 12 and the connecting plate 8.

[0029] The height of the combination of the base 1 and the guardrail column 2 is between 1.2 meters and 1.5 meters. Different heights are produced according to the needs of different municipal sections, but the height is between 1.2 meters and 1.5 meters, which meets some specifications set by the municipal guardrail standard.

[0030] In summary, the municipal engineering guardrail can be installed in two steps when in use. First, the municipal staff places the base 1 on the road and arranges it roughly. Insert the two ends of the lower crossbar 3 and the upper crossbar 5 into the inner cavity of the plug-in tube 6 on the guardrail column 2. If necessary, use bolts to pass through the plug-in tube 6 and extend to the inner cavity of the lower crossbar 3 and the upper crossbar 5 for reinforcement. Then insert the bottom end of the guardrail column 2 into the inner cavity of the base 1 to achieve the first step of installation.

[0031] Insert one end of the connecting column 10 into the inner cavity of the upper mounting plate 9 and the lower connecting plate 15, fix the connecting column 10 with bolts, then place the upper mounting plate 9 on the surface of the upper cross bar 5, make the U-shaped support plate 7 cover the isolation rod 4, and then fix the upper mounting plate 9 with bolts to complete the assembly of a set of municipal guardrails, and then connect multiple sets of municipal guardrails in sequence.
