Description

Technical Field

[0001] The utility model relates to the field of blast hole protection during open-pit blasting, and specifically to a safety warning plug for mine blasting. Background Technique

[0002] As the most popular safe, efficient, low-cost and large-scale technical means in rock excavation production, deep-hole blasting is widely used in many large-scale earthwork projects such as open-pit mine exploitation, site leveling and roadbed excavation. Both the economic benefits and safety of blasting are core contents. For the sake of benefits, the larger the diameter of the blast hole, the better the economy, and the layout of the warning line before blasting is very important.

[0003] While the large aperture brings better economic benefits, it also brings new safety hazards to mine production. The reason is that the aperture is too large and the protection of the hole mouth is insufficient, resulting in the risk that miners may step into the air and get their legs, arms or other tools stuck in the blast hole. In production, it is common for electronic devices such as mobile phones and walkie-talkies to accidentally fall into the blast hole, which not only causes economic losses, but also the batteries of the electronic devices will pose a greater danger when the blast hole is filled with explosives; for the layout of the warning line, it is often necessary to find a suitable fixing object before blasting to make the warning line noticed.

[0004] At present, in order to prevent the above situations from occurring, for the protection of the hole mouth, generally detonators, explosive packaging bags or cartons are used, or even a slightly larger stone is found near the hole mouth to temporarily seal the blast hole. Its compressive capacity is very poor and it cannot protect pedestrians and vehicles from the blast hole; for the fixation of the warning line, it is time-consuming and laborious, and it cannot ensure safety warning while reducing efficiency;

[0005] The existing safety warning plugs for mine blasting are not easy to achieve an effective warning effect and are not easy to effectively block the blast hole, which may lead to a reduction in the adaptability and portability of the device.

[0006] Therefore, a safety warning plug for mine blasting is proposed to solve the above problems. Content of the Utility Model

[0007] In order to make up for the problems in the prior art, the utility model proposes a safety warning plug for mine blasting.

[0008] The technical solution adopted by the utility model to solve its technical problems is: a safety warning plug for mine blasting described in the utility model includes a plug, a card slot is opened at the top of the plug, a rotating shaft is fixedly connected inside the card slot, the bottom end of a warning connecting piece is rotatably connected to the surface of the rotating shaft, a backlight reflecting plate is fixedly connected to the top end of the warning connecting piece, a fixing component is fixedly connected to the top of the plug, and a mounting hole is opened at a position near the lower part of the surface of the warning connecting piece.

[0024] Please refer to Figures 1 - 4 As shown, a safety warning plug for mine blasting includes a plugging block 1. A card slot 4 is opened at the top of the plugging block 1. A rotating shaft 5 is fixedly connected inside the card slot 4. The bottom end of a warning connecting piece 6 is rotatably connected to the surface of the rotating shaft 5. The top end of the warning connecting piece 6 is fixedly connected to a backlight reflecting plate 7. A fixing component 9 is fixedly connected to the top of the plugging block 1. A mounting hole 10 is opened at a position near the lower part of the surface of the warning connecting piece 6;

[0025] Furthermore, the fixing component 9 includes a mounting ring 91. A sliding column 92 is slidably installed inside the mounting ring 91. A baffle 93 is fixedly connected to the surface of the sliding column 92. One end of the sliding column 92 is fixedly connected to a cross bar 95. The size of the cross bar 95 is larger than the size inside the mounting ring 91;

[0026] During operation, due to the structural design that one end of the sliding column 92 is fixedly connected to a cross bar 95 and the size of the cross bar 95 is larger than the size inside the mounting ring 91, the cross bar 95 limits the sliding column 92, improving the stability of the sliding column 92 during operation.

[0027] Furthermore, a spring 94 is slidably sleeved on the surface of the sliding column 92. The two ends of the spring 94 respectively abut against the inner side of the baffle 93 and the inner side of the mounting ring 91;

[0028] During operation, due to the structural design that the two ends of the spring 94 respectively abut against the inner side of the baffle 93 and the inner side of the mounting ring 91, the spring 94 supports the sliding column 92 through the mounting ring 91, enabling the sliding column 92 to automatically engage with the mounting hole 10, improving the stability of the sliding column 92 during installation.

[0029] Furthermore, the shape of the plugging block 1 is a hollow inverted frustum structure with a top size larger than the bottom size;

[0030] When working, the sealing plug 1 is in the shape of a hollow inverted cone structure with a top size larger than a bottom size. The bottom of the sealing plug 1 is embedded in the blasthole, and the top of the sealing plug 1 blocks the top of the blasthole, thereby improving the stability of the sealing plug 1 installed in the blasthole.

[0031] Furthermore, a plurality of blocks 8 are fixedly connected to the surface of the warning connection piece 6, and the size of the blocks 8 is larger than the size of the warning connection piece 6;

[0032] During operation, due to the structural design that the size of the clamping block 8 is larger than that of the warning connecting piece 6 , a recessed structure is formed between the clamping blocks 8 , which has a limiting effect on the warning line bound to the surface of the warning connecting piece 6 .

[0033] Furthermore, a collar 2 is fixedly connected around the upper side of the sealing plug 1, and a steel chisel 3 is mounted inside the collar 2;

[0034] During operation, the side of the sealing plug 1 is surrounded and fixedly connected with the collar 2, and the steel chisel 3 is clamped and installed inside the collar 2, thereby improving the stability of the sealing plug 1 during installation.

[0035] Working principle: First, the hollow inverted truncated cone-shaped sealing plug 1 is embedded in the blasthole, and the steel chisel 3 penetrates the inside of the collar 2 to achieve a preliminary fixing effect on the sealing plug 1. By pulling the cross bar 95 outward and rotating the warning connector 6 to a suitable angle, the cross bar 95 is loosened, and the spring 94 supports the baffle 93 so that the slide column 92 automatically clamps the inside of the mounting hole 10, and the warning line is bound at the block 8 on the surface of the metal warning connector 6. The backlight reflective plate 7 is made of PE or PVC, and the backlight reflective material is pasted on the surface to warn the staff;

[0036] When the device is transported, the slide post 92 is moved by the cross bar 95 to disengage the slide post 92 from one of the mounting holes 10, and the warning connector 6 and the backlight reflector 7 are rotated to lower the center of gravity of the device. The hollow inverted frustum-shaped sealing plug 1 is convenient for nesting multiple groups of such items during transportation, making it easy to carry.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
