Description

Technical Field

[0001] This utility model relates to the field of road and bridge protection technology, specifically to an active rockfall interception net device for roads and bridges. Background Technology

[0002] Many mountainous towns exist in western my country. Due to land constraints, many buildings, roads, and public facilities in these cities must be built on mountain slopes. Rockfalls often occur on these mountains due to natural disasters, which can endanger pedestrians or vehicles on roads or bridges. Therefore, rockfall interception nets are set up around the mountains to provide protection.

[0003] Because falling rocks have high inertia, the interception net is easily damaged during the interception process. Damaged interception nets have reduced safety and cannot guarantee their protective effect. In addition, the interception nets need to be replaced after long-term use, but most interception nets are made of one piece, which is not convenient to disassemble and replace. Therefore, they do not meet the current needs. To address this, we propose an active rockfall interception net device for roads and bridges. Utility Model Content

[0004] The purpose of this utility model is to provide an active rockfall interception net device for roads and bridges, in order to solve the problems mentioned in the background art, which are that the falling rocks have a large inertia, making the interception net easy to be damaged during the process of intercepting rocks. The safety of the interception net decreases after damage, and its protective effect cannot be guaranteed. In addition, during use, the interception net needs to be replaced after long-term use, but most interception nets are made of one piece, which is not convenient for disassembly and replacement.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an active rockfall interception net device for roads and bridges, comprising a first mounting base, a second mounting base, and an interception net. Both ends of the second mounting base near the first mounting base are connected to fixed cones via support rods. Both ends of the interception net are fixedly connected to connecting seats. The two connecting seats are respectively installed inside the first mounting base and the second mounting base. Movable grooves are provided at both ends of the two connecting seats on the side away from each other. A limit plate is movably connected inside each of the movable grooves.

[0006] Preferably, a fixed rod is fixedly connected inside the movable groove, and a movable plate is slidably connected to the outer surface of the fixed rod. The limiting plates are all fixedly connected to the two movable plates on opposite sides.

[0007] Preferably, a spring is fixedly connected between the side of the movable plate away from the limiting plate and the inner wall of the movable groove, and the spring is wound around the outer surface of the fixed rod.

[0008] Preferably, symmetrical limiting grooves are provided on both sides inside the first mounting base and the second mounting base, and the end of the limiting plate away from the movable plate moves through the movable groove and extends to the outside of the connecting base.

[0009] Preferably, the limiting plate extends through to one end of the connecting seat and is inserted into the corresponding limiting groove.

[0010] Preferably, one of the connecting seats is fixedly connected to an upwardly inclined baffle on one side and at the front end of the second mounting seat.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model allows the movable plates on both sides of the outer surface of the connecting seat to be pinched, causing the movable plates on both sides to slide along the fixed rod, compress the spring, and move closer to each other. This causes the limiting plate to disengage from the limiting groove and move and retract into the interior of the movable groove, thereby releasing the connection with the first and second mounting seats. Subsequently, the intercepting net can be disassembled, cleaned, or replaced. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figures 1 to 3An embodiment of this utility model provides an active rockfall interception net device for roads and bridges, comprising a first mounting base 1, a second mounting base 2, and an interception net 5. Both ends of the second mounting base 2 near the first mounting base 1 are connected to fixed cones 4 via support rods 3. Both ends of the interception net 5 are fixedly connected to connecting seats 6. The two connecting seats 6 are respectively installed inside the first mounting base 1 and the second mounting base 2. Both ends of the two connecting seats 6 on the side away from each other are provided with movable grooves 601. Each movable groove 601 is movably connected to a limit plate 11.

[0019] The first mounting base 1 is installed at the bottom of the mountain, and the fixed cones 4 on both sides of the front end of the second mounting base 2 are installed at the top of the mountain. The interception net 5 between the first mounting base 1 and the second mounting base 2 can intercept falling rocks from the mountain. One side of one of the connecting seats 6, and the front end of the second mounting base 2, is fixedly connected to an upwardly inclined baffle 7. By blocking the front end of the second mounting base 2, the falling rocks can be prevented from falling onto the interception net 5 and bounced out of the outside of the interception net 5 due to elasticity.

[0020] A fixed rod 8 is fixedly connected inside the movable groove 601. A movable plate 9 is slidably connected to the outer surface of the fixed rod 8. Limiting plates 11 are fixedly connected to the two movable plates 9 on the side away from each other. A spring 10 is fixedly connected between the side of the movable plate 9 away from the limiting plate 11 and the inner wall of the movable groove 601. The spring 10 is wrapped around the outer surface of the fixed rod 8. Symmetrical limiting grooves 12 are opened on both sides inside the first mounting base 1 and the second mounting base 2. The end of the limiting plate 11 away from the movable plate 9 moves through the movable groove 601 and extends to the outside of the connecting base 6. The end of the limiting plate 11 extending to the outside of the connecting base 6 is inserted into the corresponding limiting groove 12.

[0021] By pinching the movable plates 9 on both sides of the outer surface of the connecting seat 6, the movable plates 9 on both sides slide along the fixed rod 8 to compress the spring 10 and move closer to each other, thereby causing the limiting plate 11 to disengage from the limiting groove 12 and move and retract into the interior of the movable groove 601, thereby releasing the connection with the first mounting seat 1 and the second mounting seat 2. Subsequently, the intercepting net 5 can be disassembled, cleaned or replaced.

[0022] When the active rockfall interception net device for roads and bridges is in use, the first mounting base 1 is installed at the bottom of the mountain, and the fixing cones 4 on both sides of the front end of the second mounting base 2 are installed at the top of the mountain. Then, the interception net 5 between the first mounting base 1 and the second mounting base 2 can intercept the falling rocks of the mountain. Furthermore, the baffle 7 at the front end of the second mounting base 2 can prevent the falling rocks from falling onto the interception net 5 and from bouncing out of the outside of the interception net 5 due to elasticity.

[0023] After the interception net 5 has been used for a long time, by pinching the movable plates 9 on both sides of the outer surface of the connecting seat 6, the movable plates 9 on both sides slide along the fixed rod 8 to compress the spring 10 and move closer to each other, thereby driving the limiting plate 11 to disengage from the limiting groove 12 and move and retract into the interior of the movable groove 601, thereby releasing the connection with the first mounting seat 1 and the second mounting seat 2. Then the interception net 5 can be disassembled for cleaning or replacement.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
