Description

Technical Field

[0001] This utility model relates to the field of shock-absorbing and buffer pad technology, and in particular to a recyclable shock-absorbing and buffer pad for coal mine blasting. Background Technology

[0002] Shock-absorbing pads are generally made of natural rubber and are usually used as support components to buffer, eliminate or mitigate the adverse effects of vibration. They are widely used in wearable sports products, such as insoles, shoe soles, shock-absorbing gloves, and shoulder straps, to achieve shock absorption, cushioning and protection.

[0003] In the process of coal mining, explosives, as a highly efficient mining tool, can indeed greatly improve mining efficiency and progress. However, their use is also accompanied by a series of potential risks and challenges. In particular, the impact force generated when explosives explode will cause fragments to fly everywhere, which poses a direct threat to the mechanical equipment in the mine. These fragments are of different sizes and shapes. If they collide with the mechanical equipment, especially for those delicate and vulnerable parts, such as sensors and circuit boards, the flying fragments may directly cause them to fail or be damaged. Utility Model Content

[0005] A recyclable shock-absorbing buffer pad for coal mine blasting includes a buffer plate, a buffer pad installed in the inner cavity of the front side of the buffer plate, a first buffer mechanism fixedly connected to the front side of the buffer pad, and a second buffer mechanism installed in the inner cavity of the front side of the buffer plate, with one end of the second buffer mechanism engaging with the inner cavity of the buffer pad.

[0006] As an improvement to the above technical solution, the second buffer mechanism includes an airbag, a support block, a second spring, a telescopic block, and a connecting block. One end of the airbag is fixedly connected to the inner cavity of the front side of the buffer plate, and the other end of the airbag overlaps with the rear end of the buffer pad. The front end of the support block is fixedly connected to one end of the inner cavity of the buffer plate. One end of the second spring is fixedly connected to one end of the inner cavity of the support block. A limit plate is installed on the outer wall of the telescopic block, and the outer wall of the limit plate is engaged with the inner cavity of the support block. The front end of the connecting block is fixedly connected to the rear end of the telescopic block, and the outer wall of the rear end of the connecting block is convex and engages with the inner cavity of the rear end of the buffer pad.

[0007] As an improvement to the above technical solution, the first buffer mechanism includes a buffer bump and a support plate. The rear end of the buffer bump is fixedly connected to the front end of the buffer pad, and a wear-resistant layer is installed on the outer wall of the buffer bump. The two ends of the support plate are fixedly connected to the inner cavity of the buffer bump, and the upper end of the support plate is arranged in a concentrated manner with a certain tilt angle.

[0008] As an improvement to the above technical solution, a position fixing mechanism is provided on the front side of the buffer plate;

[0009] The position fixing mechanism includes a limiting groove, a first spring, and a friction plate. The limiting groove is opened on the front side of the buffer plate.

The rear end of the friction plate is fixedly connected to the front end of the first spring, and the outer wall of the friction plate is engaged with the inner cavity of the limiting groove.

[0010] As an improvement to the above technical solution, a friction block is installed at the rear end of the buffer pad, and the friction block is convex and engages with the inner cavity of the limiting groove, and the rear end of the friction block overlaps with the front end of the friction plate.

[0011] The beneficial effects of this utility model are:

[0012] By installing a buffer plate on the machine at the location requiring protection, the first buffer mechanism absorbs the potential energy of the flying fragments generated by the explosion. When the potential energy of the fragments is large, the second buffer mechanism absorbs and buffers the potential energy of the fragments, thereby preventing the flying fragments from damaging the machinery, protecting the machinery, and ensuring the safety of the machinery during operation.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0020] Please see Figures 1-5 This utility model provides a technical solution: a recyclable shock-absorbing buffer pad for coal mine blasting, including a buffer plate 1, a buffer pad 2 installed in the inner cavity of the front side of the buffer plate 1, a first buffer mechanism 3 fixedly connected to the front side of the buffer pad 2, a second buffer mechanism 5 installed in the inner cavity of the front side of the buffer plate 1, and one end of the second buffer mechanism 5 is engaged with the inner cavity of the buffer pad 2.

[0021] By installing the buffer plate 1 on the machine at the location requiring protection, the first buffer mechanism 3 absorbs the potential energy of the flying fragments generated by the explosive explosion. When the potential energy of the fragments is large, the second buffer mechanism 5 absorbs and buffers the potential energy of the fragments, thereby preventing the flying fragments from damaging the machinery, protecting the machinery, and ensuring the safety of the machinery during operation.

[0022] Specifically, the second buffer mechanism 5 includes an airbag 51, a support block 52, a second spring 53, a telescopic block 54, and a connecting block 55. One end of the airbag 51 is fixedly connected to the inner cavity of the front of the buffer plate 1, and the other end of the airbag 51 overlaps with the rear end of the buffer pad 2. The front end of the support block 52 is fixedly connected to one end of the inner cavity of the buffer plate 1. One end of the second spring 53 is fixedly connected to one end of the inner cavity of the support block 52. A limit plate is installed on the outer wall of the telescopic block 54, and the outer wall of the limit plate is engaged with the inner cavity of the support block 52. The front end of the connecting block 55 is fixedly connected to the rear end of the telescopic block 54, and the outer wall of the rear end of the connecting block 55 is convex and engages with the inner cavity of the rear end of the buffer pad 2.

[0023] When the buffer pad 2 moves backward, it compresses the airbag 51 and causes the connecting block 55 to move backward. The connecting block 55 is convex, which ensures the stability of the connecting block 55 moving backward when the buffer pad 2 moves backward. First, the airbag 51 absorbs the potential energy of the fragments. Then, the connecting block 55 moves backward, causing the telescopic block 54 to move backward, which in turn pulls the second spring 53 to absorb the potential energy of the fragments again, thus increasing the effect of the second buffer mechanism 5 in absorbing the potential energy of the fragments.

[0024] Specifically, the first buffer mechanism 3 includes a buffer protrusion 31 and a support plate 32. The rear end of the buffer protrusion 31 is fixedly connected to the front end of the buffer pad 2, and a wear-resistant layer is installed on the outer wall of the buffer protrusion 31. The two ends of the support plate 32 are fixedly connected to the inner cavity of the buffer protrusion 31, and the upper end of the support plate 32 is arranged in a concentrated manner with a certain tilt angle.

[0025] The installed buffer bumps 31 can absorb and buffer the fragments in the first step. The support plate 32 inside the buffer bumps 31 ensures the stability of the buffer bumps 31 in absorbing the potential energy of the fragments. The cavity inside the buffer bumps 31 can absorb the shock wave generated by the explosion. At the same time, the surface of the buffer bumps 31 is equipped with a wear-resistant layer to prevent the fragments from damaging the buffer bumps 31, thus facilitating the recycling of the device.

[0026] Specifically, a position fixing mechanism 4 is provided on the front of the buffer plate 1;

[0027] The positioning fixing mechanism 4 includes a limiting groove 41, a first spring 42, and a friction plate 43. The limiting groove 41 is formed on the front side of the buffer plate 1. One end of the first spring 42 is fixedly connected to the rear end of the inner cavity of the limiting groove 41. The rear end of the friction plate 43 is fixedly connected to the front end of the first spring 42, and the outer wall of the friction plate 43 is engaged with the inner cavity of the limiting groove 41.

[0028] The friction plate 43 is moved forward by the elastic force of the first spring 42. At the same time, the outer wall of the friction plate 43 is engaged with the inner cavity of the limiting groove 41, so that the friction plate 43 moves horizontally under the elastic force of the first spring 42, thereby fixing the friction block and then fixing the buffer pad 2, ensuring the stability of the buffer pad 2 installed on the buffer plate 1.

[0029] Specifically, a friction block is installed at the rear end of the buffer pad 2. The friction block is convex and engages with the inner cavity of the limiting groove 41. The rear end of the friction block overlaps with the front end of the friction plate 43.

[0030] The friction block is convex, and its shape allows it to be positioned within the cavity of the limiting groove 41, enabling it to move horizontally up and down within the cavity. The friction block and the friction plate 43 overlap, thereby fixing the friction block and the buffer pad 2, ensuring the stability of the buffer pad 2 installed on the buffer plate 1.

[0031] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
