Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of support equipment, and specifically relates to a protective device for slope excavation protection. Background Technology
[0002] A slope is a slope with a certain gradient built on both sides of the roadbed to ensure the stability of the roadbed. Its function is to prevent rainwater erosion, stabilize the soil and protect the slope, and maintain the water and soil balance to ensure the stability of the roadbed and slope.
[0003] During slope excavation, falling rocks are a common occurrence, posing a significant safety hazard. To mitigate these hazards, current technology typically involves installing intercepting nets on the slope to block the falling rocks and prevent them from directly impacting the road surface or infrastructure below.
[0004] However, the support of existing interception nets is relatively weak. When faced with a large impact, the interception net is easily damaged, and it cannot play a good interception role. Utility Model Content
[0005] This utility model provides a protective device for slope excavation protection, which solves the technical problem that the support strength of the interception net in the prior art is relatively weak, which cannot play a good interception effect and leads to a large safety hazard in the slope excavation process.
[0006] To solve the above problems, this utility model is achieved through the following technical solution:

[0008] The protective unit includes a protective net and two first insert rods. The two first insert rods are arranged parallel to each other on both sides of the protective net, and the insertion ends of the two first insert rods extend from the lower edge of the protective net.
[0009] There are two protective units, which are parallel and opposite to each other along the slope's inclination direction. The two ends of the connector are connected to the two protective units respectively.
[0010] To better realize this utility model, the above structure is further optimized, and the protective unit also includes a rectangular protective frame;
[0011] The protective netting is laid within the protective frame;
[0012] Both of the first insertion rods are located on the lower edge of the protective frame and are arranged on both sides of the protective frame respectively, and the connectors are connected to the protective frame.

[0014] Both connectors are located on the same side of the connecting rod;
[0015] The upper edge of the protective frame is provided with a connecting sleeve for easy insertion of the plug-in part. The outer wall of the connecting sleeve is provided with a threaded hole communicating with the inside of the connecting sleeve, and a locking bolt is provided in the threaded hole. When the plug-in part is inserted into the connecting sleeve, the locking bolt abuts against the plug-in part to realize the connection between the connector and the protective frame.
[0016] To better realize this utility model, the above structure is further optimized, and the connecting rod includes an outer sleeve, an inner insert rod, and a positioning pin;
[0017] The outer sleeve has a first pin hole;
[0018] The inner insert rod is provided with multiple second pin holes, which are arranged sequentially along the length of the inner insert rod. One end of the inner insert rod is slidably disposed in the outer sleeve along the length of the outer sleeve.

[0020] To better realize this utility model, the above structure is further optimized by providing a reinforcing plate at the lower edge of the protective frame, and the two ends of the reinforcing plate are respectively connected to the two first insert rods.
[0021] To better realize this utility model, the above structure is further optimized. The protective unit also includes a second insert rod, which is disposed at the lower edge of the protective net and is parallel to the length direction of the first insert rod.

[0034] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0035] In the embodiments of this application, such as Figures 1 to 4 As shown, the protective device for slope excavation protection includes a protective unit 1 and a connector 2; wherein,
[0036] The protective unit 1 includes a protective net 11 and two first insert rods 12. The two first insert rods 12 are arranged parallel to each other on both sides of the protective net 11, and the insertion ends of the two first insert rods 12 extend from the lower edge of the protective net 11.
[0037] See Figure 1 There are two protective units 1. The two protective units 1 are parallel and opposite to each other along the slope inclination direction. The two ends of the connector 2 are connected to the two protective units 1 respectively, so that the two protective units 1 form a whole.
[0038] Before the slope is excavated, the workers can set up the protective device for slope excavation protection near the roadbed to intercept falling rocks that slide down the roadbed during the slope excavation process, so as to prevent the falling rocks from sliding into the roadbed and causing damage to the road surface or infrastructure below.
[0039] During slope excavation, if rocks slide down the slope, the protective device for slope excavation protection can effectively intercept them. The two protective units 1 can effectively increase the impact resistance of the protective device for slope excavation protection. When the first protective unit 1 (the one closer to the top of the slope) is damaged, the second protective unit 1 (the one closer to the bottom of the slope) can supplement the interception. Compared with the existing interception net, the protective device for slope excavation protection has a better interception effect and can effectively reduce the safety hazards in the slope excavation process.
[0040] Of course, two protective devices used for slope excavation protection can also be set up as a working group, with multiple working groups arranged at intervals along the extension direction of the slope to form the first working row; see also Figure 4 Specifically, in the work group, two protective devices for slope excavation protection are arranged along the extension direction of the slope, and the two protective devices for slope excavation protection are closely connected on the side that is close to each other, while the two protective devices for slope excavation protection are inclined downwards on the side that is far from each other, forming an inverted "V" shaped structure in the top view.
[0041] When a rockfall slides downwards and comes into contact with the protective device used for slope excavation protection, the rockfall will deviate from its original trajectory under the guidance of the protective device used for slope excavation protection in the first working row, such as... Figure 4 As shown by the middle arrow, this reduces the potential energy of falling rocks, preventing them from sliding into the roadbed and thus lowering safety hazards during slope excavation. Optimally, a second working row is positioned below the first working row, also composed of multiple working groups arranged at intervals. The working groups in the second working row are staggered with those in the first working row, meaning the working groups in the second working row are located in the gaps between the working groups in the first working row.
[0042] The second work row is used to further reduce the potential energy of falling rocks, thereby further reducing the safety hazards during the slope excavation process.
[0043] In some embodiments, the protective unit 1 further includes a rectangular protective frame 13; wherein,
[0044] The protective net 11 is laid in the protective frame 13, that is, the edge of the protective net 11 is connected to the protective frame 13, so as to increase the stability of the protective net 11 structure and improve the interception effect of the protective device used for slope excavation protection.
[0045] Both of the aforementioned first insert rods 12 are located on the lower edge of the protective frame 13 and are arranged close to both sides of the protective frame 13, respectively. The connector 2 is connected to the protective frame 13. Preferably, the first insert rods 12 and the protective frame 13 are integrally formed components to make the structure of the protective device for slope excavation protection more stable.
[0046] In some embodiments, the connector 2 described above includes a connecting rod 21 and two insertion portions 22, see [link to previous document]. Figure 1 and Figure 2 ;
[0047] Both plug-in parts 22 are located on the same side of the connecting rod 21;
[0048] The upper edge of the protective frame 13 is provided with a connecting sleeve 14 for easy insertion of the plug part 22. The outer side wall of the connecting sleeve 14 is provided with a threaded hole communicating with the inside of the connecting sleeve 14, and a locking bolt 15 is provided in the threaded hole.
[0049] When the plug part 22 is inserted into the connecting sleeve 14, the worker can tighten the locking bolt 15 so that the end of the locking bolt 15 inside the connecting sleeve 14 abuts against the plug part 22, thereby connecting and fixing the connector 2 to the protective frame 13, so that the structure of the protective device used for slope excavation protection is more stable.
[0050] In some embodiments, the connecting rod 21 described above includes an outer sleeve 211, an inner insert rod 212, and a positioning pin 213. See [link to documentation]. Figure 1 ;
[0051] The outer sleeve 211 is provided with a first pin hole;
[0052] The inner insert rod 212 is provided with a plurality of second pin holes, which are arranged sequentially along the length direction of the inner insert rod 212. One end of the inner insert rod 212 is slidably disposed in the outer sleeve 211 along the length direction of the outer sleeve 211.
[0053] The positioning pin 213 passes through the first pin hole and the second pin hole corresponding to the first pin hole in sequence to fix the length of the connecting rod 21;
[0054] When it is necessary to adjust the distance between the two protective units 1, the staff can first remove the positioning pin 213, and then pull the two protective units 1 away from each other or push them closer to each other so that the distance between the two protective units 1 reaches the required distance for installation. Then, the positioning pin 213 is passed through the first pin hole and the second pin hole corresponding to the first pin hole in sequence to fix the length of the connecting rod 21, thus completing the adjustment of the length of the connecting rod 21, that is, the adjustment of the distance between the two protective units 1.
[0055] Preferably, there can be multiple connecting rods 21. Connecting two protection units 1 with multiple connecting rods 21 can effectively improve the structural stability of the protection device for slope excavation protection.
[0056] To facilitate the connection between the two protective units 1 and the connecting rod 21 after installation on the slope, the position of the connecting sleeve 14 on the protective frame 13 can be adjusted to facilitate the insertion of the plug part 22 in the connector 2, thereby making the installation of the protective device for slope excavation protection more convenient.
[0057] In some embodiments, a reinforcing plate 16 is provided at the lower edge of the protective frame 13, see [reference]. Figure 1 The two ends of the reinforcing plate 16 are respectively connected to the two first insert rods 12. The reinforcing plate 16 improves the structural stability of the protective unit 1, thereby improving the structural strength of the protective device used for slope excavation protection.
[0058] In some embodiments, the protective unit 1 described above further includes a second insert 17, see [reference needed]. Figure 3 The second insert rod 17 is set at the lower edge of the protective net 11, and the second insert rod 17 is parallel to the length direction of the first insert rod 12. The second insert rod 17 can further improve the stability of the protective unit 1 installed on the slope, so as to improve the interception effect of the protective device used for slope excavation protection.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
