Description

Technical Field

[0001] This utility model relates to the field of civil defense safety technology, and in particular to protective netting for blasting projects. Background Technology

[0002] Although blasting is highly destructive and requires protective structures to protect people or property near the blast site, in many cases, blasting operations are only carried out once, and the effective time of blasting protective structures is very short. After the blasting operation is completed, the protective structures that have been painstakingly built are abandoned after fulfilling their protective function, or they are demolished because they occupy land resources. This causes a great waste of resources and needs to be improved. For this reason, a blasting engineering protective net was designed. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this utility model is to propose a protective net for blasting engineering that saves resources and has high assembly efficiency.

[0005] Preferably, a plurality of first bolts are threadedly fixed between the connecting plate and the support rod, and the surface of the first bolts is fitted with a washer.

[0006] Preferably, a plurality of second bolts are fixed between the connecting plate and the anti-collision plate.

[0007] Preferably, the surface of the anti-collision plate has multiple mounting holes, a steel sleeve is fixed inside the mounting holes, a third bolt is installed inside the steel sleeve, and multiple locking nuts are threaded on the surface of the third bolt.

[0008] Preferably, each of the four corners of the surface of the gun shell is fixed with a fitting ring, which is fitted onto the surface of the third bolt and located between the locking nuts.

[0009] Preferably, the anti-collision plate includes multiple horizontally arranged plates, and the two ends of the plates are respectively fixed to the connecting plates on both sides.

[0010] The beneficial effects of this utility model are:

[0011] 1. At the guardrail location, quick replacement can be performed according to the blasting direction, saving resources and with high assembly efficiency;

[0012] 2. It can reinforce and assemble old guardrail structures of suitable size, and reuse the structure to further save resources. Attached Figure Description

[0019] Reference Figure 1-5 The blasting engineering protective net includes multiple support rods 1, with guardrail nets 2 fixed between each support rod 1, connecting plates 3 fixed to the surface of the support rods 1, anti-collision plates 4 fixed between the connecting plates 3, and blasting covers 5 covering the surface of the anti-collision plates 4.

[0020] Multiple first bolts 6 are threadedly fixed between the connecting plate 3 and the support rod 1. A washer 7 is fitted on the surface of the first bolt 6. The washer 7 provides an installation surface for the first bolt 6. The washer 7, together with the connecting plate 3, provides external support for the support rod 1 and improves the support strength of the support rod 1.

[0021] Multiple second bolts 8 are fixed between the connecting plate 3 and the anti-collision plate 4.

[0022] Multiple mounting holes 9 are provided on the surface of the anti-collision plate 4. A steel sleeve 10 is fixed inside the mounting holes 9. A third bolt 11 is installed inside the steel sleeve 10. The locking nut 12 can also lock the third bolt 11, locking the third bolt 11 to the surface of the anti-collision plate 4. Furthermore, if the length of the third bolt 11 allows, the distance between the shell 5 and the anti-collision plate 4 can be adjusted by adding multiple locking nuts 12. The specific implementation can be adjusted according to the current installation situation. Multiple locking nuts 12 are threaded on the surface of the third bolt 11. Since the third bolt 11 is used to support the shell 5, when the shell 5 is hit by falling rocks, the third bolt 11 will vibrate. The vibration of the third bolt 11 will cause damage to the connection with the anti-collision plate 4. By installing the steel sleeve 10, the third bolt 11 and the anti-collision plate 4 are separated. When the third bolt 11 vibrates, its contact object is the steel sleeve 10, not the anti-collision plate 4. The steel sleeve 10 has high hardness and is not easily worn.

[0023] Each of the four corners of the surface of the gun shell 5 is fixed with a sleeve ring 13, which is fitted onto the surface of the third bolt 11 and located between the locking nuts 12.

[0024] The anti-collision plate 4 includes multiple horizontally arranged plates. The two ends of the plates are fixed to the connecting plates 3 on both sides. The connecting plates 3 are configured according to the height of the support rod 1. If the vertical height of the connecting plate 3 is very high, the anti-collision plate 4 cannot be installed as a whole. Therefore, the anti-collision plate 4 is divided into multiple plates, and the plates are fixed between the connecting plates 3 in stages to achieve the overall arrangement of the anti-collision plate 4 and reduce the difficulty of arranging the anti-collision plate 4.

[0025] When using this device, multiple through holes are opened on the surface of the support rod 1. The pad 7 and the connecting plate 3 are arranged on both sides of the through holes. The first bolt 6 is passed through the pad 7, the through holes and the connecting plate 3 in sequence. It is best to install a nut at the end of the first bolt 6 to fix the connecting plate 3 to the surface of the support rod 1. A collision protection plate 4 is installed between the connecting plates 3. The collision protection plate 4 and the connecting plate 3 are fixed by the second bolt 8. Finally, the third bolt 11 is passed through the steel sleeve 10. A locking nut 12 is first threaded on one end of the third bolt 11 that passes through the steel sleeve 10. Then, the sleeve ring 13 of the shell 5 is connected to the third bolt 11. Another locking nut 12 is threaded on. The two locking nuts 12 are used to fix the sleeve ring 13, and finally the shell 5 is fixed.

[0026] The above is the installation process of the protective netting for this blasting project. When blasting operations are carried out at different angles, the connecting plate 3 can be removed from the surface of the support rod 1, and then the connecting plate 3, the anti-collision plate 4 and the blasting cover 5 can be removed from the support rod 1 as a whole. They can then be rearranged on the surface of the support rod 1 in other directions according to the blasting direction, so as to achieve quick disassembly and repositioning and reuse.

[0027] For the protective netting of this blasting project, if there are existing old guardrail structures of similar size to support rod 1 and guardrail net 2 in the blasting area, the connecting plate 3, anti-collision plate 4 and blasting cover 5 can be directly installed on the side of the existing guardrail to reinforce the old guardrail.
