[0002] Blasting engineering refers to the excavation of earth and stone, the demolition or destruction of foundations, buildings and structures using explosives. When explosives explode, they produce a large amount of gas and release energy, which causes strong compression and destruction to the surrounding medium. Before blasting, explosives need to be filled into the blast hole and a detonating cord needs to be installed, so the blast hole needs to be supported.

[0003] Chinese patent with authorization announcement No. CN215064122U discloses a reinforcing support device for blasting engineering. The support mechanism is used to connect the side support to the cord tube, and the connecting rod is connected to the sleeve rod through the connecting slot. By adjusting the connection position of the sleeve rod and the connecting rod, the side support can be pressed against the inner wall of the blast hole. The four sets of side supports and the four sets of support mechanisms achieve the effect of reinforcing and supporting the blast hole. The reinforcing support device for blasting engineering has the advantages of low working intensity, simple operation and easy use.

[0004] Although the reinforcing support device for blasting engineering has the advantages of low working intensity, simple operation and easy use, it lacks a positioning device for the explosive cord on the support mechanism. After the installation of the cord is completed, the cord may be pulled off during the subsequent process, affecting the subsequent blasting effect. Therefore, we propose a reinforcing support device for blasting engineering. UTILITY MODEL CONTENTS

[0022] 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.

[0023] Example 1

[0024] like Figures 1-4 As shown;

[0025] A reinforcement and support device for blasting engineering, comprising:

[0026] Fixed cylinder 1, with fixed crossbars 12 fixed on both sides of the inner wall of fixed cylinder 1, and a threaded coil 2 fixedly connected to the inner side of the fixed crossbar 12. A telescopic spring 4 is welded to both sides of the inner wall of the threaded coil 2. An elastic block 3 is glued to one end of the telescopic spring 4, and an anti-slip patch 5 is glued to the inner side of the elastic block 3. Fixed rod 7, which is fixedly connected to the outer wall of fixed cylinder 1, with a threaded rod 8 threadedly connected to one end of the fixed rod 7. A positioning bearing 9 is fixed to one end of the threaded rod 8, and an outer ring top block 10 is fixed to one end of the positioning bearing 9.

[0027] In this implementation plan: the telescopic spring 4 and the elastic block 3 can clamp the lead wire inside the coil 2, thereby improving the firmness of the lead wire. The anti-slip patch 5 can improve the friction between the elastic block 3 and the lead wire, thereby improving the anti-slip performance. This avoids the problem that the support mechanism lacks a positioning device for the explosive lead wire, which can easily cause the lead wire to detach due to subsequent pulling or other processes after the lead wire is installed, thus affecting the subsequent blasting effect.

[0028] Furthermore:

[0029] In an optional embodiment, the fixed cylinder 1 is connected to the threaded coil 2 via a fixed crossbar 12, and the center point of the threaded coil 2 coincides with that of the fixed cylinder 1.

[0030] In this implementation plan: the use of coil 2 facilitates the installation of the explosive fuse.

[0031] Furthermore:

[0032] In an optional embodiment, the threading coil 2 forms an elastic structure between the extension spring 4 and the elastic block 3, and the anti-slip patch 5 is tightly attached to the inner side of the elastic block 3.

[0033] In this implementation scheme: the extension spring 4 and the elastic block 3 can clamp the lead wire in the coil 2, thereby improving the firmness of the lead wire. The anti-slip patch 5 can improve the friction between the elastic block 3 and the lead wire, thereby improving the anti-slip performance.

[0034] Furthermore:

[0035] In an optional embodiment, a packing ring 6 is fixedly connected between the fixing rods 7.

[0036] In this implementation plan: the interior of the packing ring 6 and the fixing cylinder 1 is convenient for filling explosive materials, and the explosive materials can be accurately filled into the blast hole.

[0037] Furthermore:

[0038] In an optional embodiment, the threaded rod 8 is rotatably connected to the fixed rod 7, and the threaded rod 8 is movably connected to the outer ring top block 10 via the positioning bearing 9.

[0039] In this implementation scheme: the threaded rod 8 can rotate relative to the fixed rod 7, and the outer ring top block 10 can be moved outward through the cooperation of the positioning bearing 9, so that the position of the outer ring top block 10 can be adjusted sequentially according to the shape of the blast hole, until the device is firmly supported in the blast hole by the outer ring top block 10.

[0040] Furthermore:

[0041] In an optional embodiment, an elastic patch 11 is adhered to the outer side of the outer ring top block 10, the outer ring top block 10 is symmetrically distributed about the center point of the fixing cylinder 1, and the elastic patch 11 is attached to the outer wall of the outer ring top block 10.

[0042] In this implementation scheme: the rubber elastic patch 11 can improve the flexibility and anti-slip properties of the outer ring top block 10, thereby improving the tightness between the outer ring top block 10 and the inner wall of the borehole.

[0043] Working principle: When using this reinforcement support device for blasting engineering, firstly, place the support frame inside the blast hole that needs reinforcement. Rotate the threaded rod 8 and the fixed rod 7 relative to each other. Through the cooperation of the positioning bearing 9, the outer ring top block 10 can be moved outward. Thus, according to the shape of the blast hole, the position of the outer ring top block 10 can be adjusted sequentially until the device is firmly supported inside the blast hole by the outer ring top block 10. Secondly, the rubber elastic patch 11 improves the flexibility and anti-slip properties of the outer ring top block 10, thereby improving the tightness between the outer ring top block 10 and the inner wall of the blast hole. Then, the explosive materials are filled into the filler. The interior of ring 6 and the fixed cylinder 1 allows for precise filling of explosive materials into the blast hole, while the filling ring 6 facilitates the even distribution of explosives. Finally, the explosive fuse is installed into the threading coil 2, the elastic block 3 is opened, the explosive fuse is threaded through the inner side of the elastic block 3, and then the elastic block 3 is released. The elastic block 3 can be moved towards the center by the telescopic spring 4, thereby clamping the fuse in the threading coil 2 and improving the fuse's firmness. At the same time, the anti-slip patch 5 increases the friction between the elastic block 3 and the fuse, thereby improving the fuse's anti-slip properties. This is the working principle of the reinforcement support device used in this blasting project.
