Description

Technical Field

[0001] This utility model is a civil engineering slope ecological protection device, belonging to the field of slope ecological protection technology. Background Technology

[0002] In earthwork engineering, the sloping free surface created by excavation or filling is called an earthwork slope. Since slopes in civil engineering projects may collapse during construction, the existing treatment method is to pour concrete on the slope surface. This practice is highly destructive to the ecology of the slope.

[0003] According to Chinese Patent CN202122542601.3, an ecological protection device for slopes in civil engineering projects is proposed. This application improves the stability of the protection device by dividing a large area of ​​protective netting into several smaller areas and securing them with fixing plates. This prevents the risk of slope collapse and greatly enhances and ensures the safety and stability of the slope. Furthermore, this invention is easy and simple to install; simply driving ground nails and fasteners into the slope is sufficient to fix the protective netting and fixing plates, improving installation efficiency. Existing fixing plates cannot be adjusted in length, thus limiting their applicability to protective netting of different sizes. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-7This utility model provides a technical solution for an ecological protection device for civil engineering slopes, including a protective net 1 and a fixing frame 2. The fixing frame 2 has symmetrically arranged connecting seats 3 on both sides. One side of each connecting seat 3 has a slot 4 that matches the protective net 1. The top of each connecting seat 3 has several evenly distributed ground nails 5 that penetrate both the protective net 1 and the connecting seat 3. Both the protective net 1 and the connecting seat 3 have mounting holes 6 that match the ground nails 5. The fixing frame 2 also has symmetrically arranged adjusting frames 7 on both sides. The two sets of adjustment frames 7 are connected to the fixed frame 2 through the spacing adjustment assembly. The adjustment frame 7 has symmetrically arranged connecting seats 8 on both sides. One side of the connecting seat 8 has a slot 9 that matches the protective net 1. The top of the connecting seat 8 has a ground nail 10 that penetrates the protective net 1 and the connecting seat 8. The protective net 1 and the connecting seat 8 both have mounting holes 11 that match the ground nail 10. The top of the adjustment frame 7 has symmetrically arranged expansion bolts 12 that penetrate the adjustment frame 7.

[0017] See Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The spacing adjustment assembly includes a placement slot 13 in the fixed frame 2, a connecting shaft 14 in the placement slot 13, a drive gear 15 fixedly sleeved on the outer wall of the connecting shaft 14, and drive slide plates 16 on both sides of the drive gear 15. Each set of drive slide plates 16 has meshing teeth 17 that match the drive gear 15. One end of each set of drive slide plates 16 extends outside the fixed frame 2 and is connected to two sets of adjustment frames 7 respectively. The top end of the connecting shaft 14 extends outside the fixed frame 2 and is connected to a locking assembly. Sliding holes matching the drive slide plates 16 are provided on both sides of the fixed frame 2. The locking assembly includes a locking sleeve 18 at the top of the fixing frame 2, a connecting shaft 14 extending into the locking sleeve 18 and connecting to a pull rod 19, a sliding groove 25 matching the pull rod 19 at the top of the connecting shaft 14, a limiting key 20 on the outer wall of the pull rod 19, a keyway matching the limiting key 20 on the inner wall of the sliding groove 25, a limiting gear 21 fixedly sleeved at the top of the connecting shaft 14 and on the outer wall of the pull rod 19, an internal gear ring 22 matching the limiting gear 21 fixedly sleeved on the inner wall of the locking sleeve 18, a return spring 23 sleeved at the top of the limiting gear 21 and on the outer wall of the pull rod 19, and a pull rod 19 extending out of the locking sleeve 18 and connecting to a rotating wheel 24.

The outer wall of the rotating wheel 24 is fitted with an anti-slip rubber sleeve.

[0018] When adjusting the overall length of the fixing frame 2, first pull the rotating wheel 24 upwards. The rotating wheel 24 drives the pull rod 19 upwards, which in turn drives the limit gear 21 upwards, disengaging it from the internal gear ring 22. At this point, the limit is released and the return spring 23 is compressed. Rotating the rotating wheel 24 drives the pull rod 19 to rotate, which in turn drives the connecting shaft 14 to rotate via the limit key 20. The connecting shaft 14 drives the drive gear 15 to rotate, and the drive gear 15 drives the two sets of drive slide plates 16 to move via the meshing teeth 17. The two sets of drive slide plates 16 then drive the two sets of adjusting frames 7 to move synchronously away from or close to each other, thus changing the overall length of the fixing frame 2. Releasing the rotating wheel 24 releases the return spring 23, which then resets and drives the limit. Gear 21 moves and engages with internal gear ring 22 for limiting. Then, the fixing frame 2 is fixed to the slope by expansion bolt 12. Then, the middle side of the protective net 1 is inserted into slot 4 on connecting seat 1 3, and the two sides of the protective net 1 are inserted into slot 2 9 on connecting seat 2 8. Then, the protective net 1 is fixed to connecting seat 1 3 and connecting seat 2 8 by ground nail 1 5 and ground nail 2 10. By setting the spacing adjustment component, the personnel can adjust the overall length of the fixing frame according to the actual size of the protective net. At the same time, the spacing adjustment component can adjust the distance between the two sets of adjustment frames through the cooperation of connecting shaft, drive gear, drive slide plate, meshing teeth and locking component, thereby adjusting the overall length of the fixing frame. It is flexible and convenient to use, and the adjustment is more stable.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
