Description

Technical Field

[0001] This utility model relates to the field of road construction protection technology, specifically a rockfall protection device for mountain road construction. Background Technology

[0002] Mountain road construction is a complex and time-consuming project. Rockfalls are very common in mountainous areas, and rockfalls are one of the common geological hazards in mountain road construction projects. Rockfalls, rolling down, and accumulating at the construction site are difficult to deal with once they occur, and can cause serious casualties. Therefore, it is essential to protect against rockfalls.

[0003] Currently, most of the rockfall protection devices used are protective net structures. The protective net is fixed to the surface of the rock to reinforce it and reduce the risk of collapse and rolling. However, most of the protective nets are integral structures, which makes it inconvenient to increase or decrease the protective coverage area according to the size of the rock, and they are not flexible enough. Moreover, a single protective net is not strong enough. When rock fragments fall off, they can easily hit the protective net and cause it to fall off. Therefore, improvements are urgently needed. Utility Model Content

[0004] The purpose of this utility model is to provide a rockfall protection device for mountain road construction, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rockfall protection device for mountain road construction, comprising a protective net body, a wire mesh, tension cables, connecting hooks, and support rods. The wire mesh is fixed inside the protective net body. The tension cables are installed at the bottom and both sides of the bottom of the protective net body. The connecting hooks are all located between the protective net bodies, and both ends of the connecting hooks penetrate the wire mesh and are provided with locking holes. A threaded locking rod passes through the locking holes. The support rods are all located on one side of the protective net body and are welded to the protective net body.

[0006] Preferably, one end of the traction cable is provided with a rock nail to facilitate fixing the traction cable to the surface of the dangerous rock.

[0007] Preferably, the connecting hooks are provided in three sets and are evenly distributed at the top, middle and bottom, making the splicing of the main body of the protective net more firm and reliable.

[0008] Preferably, both ends of the threaded locking rod pass through the locking hole and are fitted with nuts, and the nuts are threadedly connected to the threaded locking rod to facilitate fixing the threaded locking rod.

[0009] Preferably, a ground nail is inserted through the bottom end of the support rod to facilitate fixing the support rod.

[0010] Preferably, a support plate is welded to the outer wall of the support rod near the main body of the protective net, and one end of the support plate is welded to the main body of the protective net. A detection box is installed at the top of the support plate, and a collision sensor is installed inside the detection box to facilitate the detection of impacts from falling rocks.

[0011] Preferably, an alarm is installed at the top of the detection box, and the alarm is electrically connected to the collision sensor to facilitate alarm notification when rocks fall.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By splicing the main bodies of the protective net together, and then attaching connecting hooks between them, with one end of the hook passing through the wire mesh, and then inserting the threaded locking rod into the locking hole and tightening the nut to secure the threaded locking rod, the main bodies of the protective net can be assembled in pairs. This allows for easy adjustment of the protective coverage area according to the size of the dangerous rock, making it flexible and convenient to use. Support rods are fixed to the ground with ground nails, providing diagonal bracing for the main bodies of the protective net and reinforcing them. When loose rocks or rubble fall and hit the main bodies of the protective net, they are less likely to detach, thus enhancing the protective force. Attached Figure Description

Therefore, the following detailed description of the embodiments of this utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but merely to illustrate selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0021] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5 One embodiment of this utility model is a rockfall protection device for mountain road construction, which includes a protective net body 1, a wire mesh 101, a tension cable 2, a connecting hook 4 and a support rod 8. The wire mesh 101 is fixed inside the protective net body 1, and the tension cables 2 are installed at the bottom end and on both sides of the bottom end of the protective net body 1.

[0023] Specifically, the protective net body 1 and the wire mesh 101 together constitute a protective structure. The protective net body 1 is covered on the surface of the dangerous rock, and the rock nail 3 at one end of the pulling steel cable 2 is fixed in the rock. This can fix the protective net body 1 on the surface of the dangerous rock and reduce the collapse and rolling of the dangerous rock.

[0024] All connecting hooks 4 are set between the main body 1 of the protective net, and both ends of the connecting hooks 4 pass through the wire mesh 101 and are provided with locking holes 5, and threaded locking rods 6 pass through the inside of the locking holes 5.

[0025] Specifically, the main body 1 of the protective net is spliced ​​together, and the connecting hook 4 is clipped between the main body 1 of the protective net. One end of the connecting hook 4 passes through the wire mesh 101, and the threaded locking rod 6 is inserted into the locking hole 5. The nut 7 is tightened to fix the threaded locking rod 6. The main body 1 of the protective net can be spliced ​​together in pairs, which makes it easy to increase or decrease the protective coverage area according to the size of the dangerous rock, and is flexible and convenient to use.

[0026] All support rods 8 are installed on one side of the main body 1 of the protective net, and the support rods 8 are welded to the main body 1 of the protective net;

[0027] One end of the tension cable 2 is fitted with a rock nail 3;

[0028] The connecting hooks 4 are provided in three sets and are evenly distributed at the top, middle and bottom.

[0029] Both ends of the threaded locking rod 6 pass through the locking hole 5 and are fitted with nuts 7, and the nuts 7 are threadedly connected to the threaded locking rod 6;

[0030] A ground nail 9 is inserted through the bottom end of the support rod 8;

[0031] Specifically, the support rod 8 is fixed to the ground by the ground nail 9. The support rod 8 provides diagonal support to the main body 1 of the protective net and reinforces the main body 1 of the protective net. When dangerous rocks and rubble fall and hit the main body 1 of the protective net, the main body 1 of the protective net is not easy to fall off, thereby improving the protective force.

[0032] A support plate 10 is welded to the outer wall of the support rod 8 near the main body 1 of the protective net, and one end of the support plate 10 is welded to the main body 1 of the protective net. A detection box 11 is installed on the top of the support plate 10, and a collision sensor 12 is installed inside the detection box 11.

[0033] The collision sensor 12 is a ball-type collision sensor, also known as a biased magnet collision sensor. Its principle is as follows: When the sensor is stationary, under the action of the permanent magnet, the ball in the guide cylinder is attracted to the magnet, the two contacts separate from the ball, and the sensor circuit is disconnected. When the collision and deceleration reach the set threshold, the inertial force generated by the ball will be greater than the electromagnetic attraction of the permanent magnet. Under the action of the inertial force, the ball will overcome the magnetic force and move along the guide cylinder to the two fixed contacts, and connect to the fixed contacts, triggering the alarm 13 to provide an alarm reminder. The collision sensor 12 is an existing product, so it will not be described in detail in the attached figure.

[0034] An alarm 13 is installed at the top of the detection box 11, and the alarm 13 is electrically connected to the collision sensor 12.

[0035] Specifically, when the loose rocks fall and hit the main body of the protective net 1, the impact force is transmitted to the collision sensor 12 inside the detection box 11. After the collision sensor 12 detects the impact, it triggers the alarm 13 to issue an audible and visual alarm, reminding on-site personnel to deal with it in time. This can provide early warning of the collapse of the loose rocks and further improve safety.

[0036] In use, the following steps are taken in this embodiment: First, the rockfall protection device is composed of a protective net body 1 spliced ​​together. The protective net body 1 and the wire mesh 101 together form a protective structure. The protective net body 1 is covered on the surface of the rockfall, and the rock nail 3 at one end of the tension cable 2 is fixed inside the rock. This fixes the protective net body 1 to the surface of the rockfall, reducing the risk of rockfall collapse and rolling. Then, according to the area of ​​the rockfall, the protective net bodies 1 are spliced ​​together. The connecting hook 4 is then inserted between the protective net bodies 1, with one end of the connecting hook 4 passing through the wire mesh 101. The threaded locking rod 6 is then inserted into the locking hole 5, and the nut 7 is tightened to fix the threaded locking rod 6. This completes the splicing of the protective net bodies 1 in pairs. The protective netting is installed in a way that allows for easy adjustment of the protective coverage area based on the size of the dangerous rock, making it flexible and convenient to use. Next, the support rods 8 are fixed to the ground using ground nails 9. The support rods 8 provide diagonal bracing to the main body 1 of the protective netting, reinforcing it. When debris from the dangerous rock falls and hits the main body 1, the main body 1 is less likely to fall off, thus improving its protective strength. Furthermore, when debris from the dangerous rock falls and hits the main body 1, the impact force is transmitted to the collision sensor 12 inside the detection box 11. After detecting the impact, the collision sensor 12 triggers the alarm 13 to emit an audible and visual alarm, reminding on-site personnel to handle the situation promptly. This provides early warning of potential rockfalls and further improves safety.

[0037] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
