Description

Technical Field

[0001] The utility model belongs to the technical field of mining protection, and in particular relates to safety protection equipment for blasting in mine development. Background Art

[0002] At present, blasting is often used in mining, which uses the combined effect of explosion stress wave and detonation gas to crush the ore. During the crushing process, a large amount of flying rocks will fall onto the road at the foot of the mine. Therefore, it is necessary to install protective equipment on both sides of the road to intercept flying rocks, so as to reduce the safety damage caused by flying rocks to passing vehicles and pedestrians on the road.

[0003] After searching, the publication number: CN216974919U announced a mining machinery safety protection device used in mining. In the utility model, a protective plate is placed on the top of the mounting frame, and the protective plate is fixed on the top of the mounting frame by bolts and other fasteners. The hydraulic rod is adjusted, and the hydraulic rod drives the connecting column to move, and then drives the support frame to move. The support frame drives the support frame to move, so that the distance between the support frame and the equipment changes. The threaded sleeve is rotated, and the threaded sleeve and the support screw cooperate to change the height of the support frame. The height of the support frame is adjusted until the walking wheel is in contact with the ground. At this time, the support frame and the support frame can support the mounting frame, but the middle position of the mounting frame of this device is hollow, which will reduce the support effect to a certain extent, thereby reducing the protection level.

[0004] Therefore, a safety protection device for blasting in mines is designed to solve the above problems. Utility Model Content

[0005] To solve the problems raised in the above background technology. The utility model provides a safety protection device for blasting in mining. When in use, the device can be connected to an external water pump and connected to the bottom water inlet through a pipe. Since there is a lot of dust in mining at the construction site, the support legs can spray atomized water on the outside through the top atomizing nozzle while supporting and protecting the periphery. The atomized water droplets combine with the dust to purify the construction environment. On the other hand, two groups of support legs can be set up, and the positioning frame can be attached to the surface of the threaded steel plate and connected with bolts. The flexible protective net in the frame can block the small gravel splashed during blasting, thereby ensuring construction safety.

[0006] This device can pull out the adjustment bracket along both sides of the inclined roof frame, thereby increasing the top lateral interception area and improving the protection range. At the same time, the L-shaped pull-out frame on the outside of the horizontal bracket can be adjusted synchronously with the movement of the adjustment bracket. In this process, the reinforced ribs on the horizontal bracket play a role in strengthening the support, and the damping rod at the interval of the ribs contracts along the inner rod when the inclined roof frame is impacted, thereby compressing the spring support. With the support of the spring, the outer inclined roof frame can resist the impact of large external rocks, thereby improving the stability of the overall device.

The hydraulic rod is adjusted, and the hydraulic rod drives the connecting column to move, thereby driving the support frame to move. The support frame drives the support frame to move, so that the distance between the support frame and the equipment changes. The threaded sleeve is rotated, and the threaded sleeve cooperates with the support screw to change the height of the support frame. The height of the support frame is adjusted until the walking wheels are in contact with the ground. At this time, the support frame and the support frame can support the mounting frame. However, the middle position of the mounting frame of this device is hollow, which will reduce the support effect to a certain extent, thereby reducing the protection level. On this basis, a high-efficiency protection mechanism 1 is added.

[0028] In this embodiment: an external water pump can be connected to the bottom water inlet 7 through a pipe. Since there is a lot of dust from mining at the construction site, the support legs 11 can spray atomized water on the outside through the top atomizing nozzle 6 while providing peripheral support and protection. The atomized water droplets combine with the dust to purify the construction environment. On the other hand, two groups of support legs 11 can be provided, and the positioning frame 12 can be attached to the surface of the threaded steel plate 5 and connected with bolts.

Under the support of the spring, the outer inclined roof frame 14 can resist the impact of large external rocks, thereby improving the stability of the overall device.
