Description

Technical Field

[0001] The utility model relates to the field of coal mines, in particular to a coal mine safety information display warning device. Background Art

[0002] Coal mines are areas where humans exploit coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, people generally choose to dig tunnels underground to mine coal. This is an underground coal mine. When the coal seam is very close to the surface, people generally choose to directly strip off the surface soil layer to mine coal. This is an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines. The scope of coal mines includes a large area above and below the ground and related facilities. Coal mines are reasonable spaces excavated by humans when digging geological strata rich in coal. They usually include tunnels, shafts, mining faces, etc. In the production process of coal mines, some dangerous areas underground in the mine usually use safety information display warning devices such as fences to prevent people from approaching.

[0003] After searching, a utility model safety warning device with publication number CN217149983U was found. The safety warning device includes: a mounting seat; a warning component, which is mounted on the mounting seat, and the warning component includes a light sensing display device, which includes a light sensing part and a display part, and the light sensing part can control the luminous intensity of the display part according to the intensity change of the external ambient light. The safety warning device of the technical solution of the utility model has a good warning effect and can meet the requirements of use in dim light and dusty environment at night.

[0004] The existing coal mine safety information display warning device is just a single warning sign plugged into the area where warning is required, which has certain limitations. Moreover, when in use, it is unable to provide obvious warning effects on safety information according to the situation on site and expand the warning range. The safety warning device in the above-mentioned comparative case is also a whole and cannot expand its warning range and intercept it according to the actual warning situation on site. Therefore, long-term use not only requires multiple sets of coal mine safety information display warning devices to enclose the warning area, but also increases the warning cost.

[0005] Therefore, it is necessary to invent a coal mine safety information display warning device to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a coal mine safety information display warning device, which can pull the first bracket and the second bracket apart by pulling the connecting columns on both sides, and at the same time, the telescopic frame under the connecting column is telescoped out on both sides inside the base, thereby achieving the expansion effect, so as to solve the problems raised in the above-mentioned background technology.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a coal mine safety information display warning device, comprising a base for supporting the safety information display warning device;

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The utility model provides Figure 1-5 A coal mine safety information display warning device shown includes a base 1 for supporting the safety information display warning device;

[0029] The telescopic frame 5 is movably connected to the inside of both sides of the base 1 for telescopic expansion. The upper surface of the telescopic frame 5 is provided with a limiting groove 6. A connecting column 8 is fixedly installed on the upper side of the telescopic frame 5.

[0030] The limiting mechanism 7 is fixedly mounted on both sides of the base 1 and is used to limit the telescopic frame 5. The first bracket 1103 and the second bracket 1105 are pulled apart by pulling the connecting columns 8 on both sides. At the same time, the telescopic frame 5 below the connecting column 8 is extended and retracted inside the base 1, thereby improving stability. When the telescopic frame 5 is pulled apart, the limiting block 705 rebounds in the limiting groove 6 in the telescopic frame 5 through the spring 704. Since the limiting block 705 is set in a trapezoidal shape, it will not be hindered when pulled out, but will be blocked by the limit when retracted. In this way, the deployment effect is completed, which is suitable for complex ground conditions.

[0031] A support plate 9 is fixed above the base 1 and is used to paste a warning sign 10. A warning sign 10 is arranged in front of the support plate 9. A telescopic mechanism 11 is provided between the support plate 9 and the connecting column 8. A lamp 12 is arranged on the upper front side of the support plate 9. A warning light 13 is fixedly installed above the support plate 9. The warning sign 10 can display safety information to warn the surrounding people, and the setting of the lamp 12 can clearly see the content of the warning sign 10 at night.

[0032] like Figure 1 and Figure 2 As shown, a connecting frame 2 is fixedly installed on the front and rear sides of the base 1, a screw rod 3 runs through the interior of the connecting frame 2, and a fixing pin 4 is fixedly installed on one end of the screw rod 3. Turning the screw rod 3 on the front and rear sides of the base 1 drives the fixing pin 4 to extend and retract, and the fixing pin 4 is firmly fixed in the ground, thereby improving the overall stability.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, the limiting mechanism 7 includes a connecting block 701, a telescopic rod 702, a handle 703, a spring 704, and a limiting block 705. The connecting block 701 is fixed on both sides of the base 1. The connecting block 701 is movably connected with the telescopic rod 702 inside. The handle 703 is fixedly installed on the upper end of the telescopic rod 702. The spring 704 is arranged on the outside of the telescopic rod 702. The limiting block 705 is fixedly installed on the lower end of the telescopic rod 702. When the telescopic frame 5 is extended and retracted from both sides inside the base 1, the limiting block 705 is rebounded and limited by the limiting groove 6 of the telescopic frame 5 through the spring 704, so as to adjust the unfolded position of the telescopic frame 5 and also enhance the stability of the telescopic part.

[0034] like Figure 2 and Figure 3 As shown, the limit groove 6 opened on the upper surface of the telescopic frame 5 matches the limit block 705, and the limit block 705 is set in a trapezoidal shape. Because the limit block 705 is trapezoidal, the telescopic frame 5 will not be hindered when it is pulled out, but will be blocked when it is retracted.

[0035] like Figure 1 , Figure 2 and Figure 4 As shown, the telescopic mechanism 11 includes a fixed frame 1101, a limiting slide groove 1102, a first bracket 1103, a movable shaft 1104, and a second bracket 1105. The fixed frame 1101 is fixed on one side of the support plate 9 and the connecting column 8. The inner surface of the fixed frame 1101 is provided with a limiting slide groove 1102. The inner part of the limiting slide groove 1102 is movably connected with the first bracket 1103. One end of the first bracket 1103 is movably connected with the movable shaft 1104. The outer part of the movable shaft 1104 is movably connected with the second bracket 1105. When the connecting column 8 is pulled apart, the first bracket 1103 and the second bracket 1105 will be pulled apart, thereby completing the telescopic effect, so that it is suitable for various conditions and meets the user's requirements for length.

[0036] like Figure 4 As shown, the first bracket 1103 and the second bracket 1105 are cross-arranged, and the first bracket 1103 is limitedly slidably connected to the fixing bracket 1101 and is unfolded by folding, which not only improves the stability during extension and retraction, but also facilitates storage.

[0037] The working principle of the utility model is as follows: first, the whole device is pushed to the position where the coal mine needs to be warned, and then the screw rods 3 on the front and rear sides of the base 1 are screwed to drive the fixing pin 4 to extend and retract, and the fixing pin 4 is firmly penetrated into the ground, thereby improving the overall stability. Then, when the whole device needs to be unfolded according to the on-site environment and the requirements of the staff, the connecting columns 8 on both sides are pulled to pull the first bracket 1103 and the second bracket 1105 apart, and at the same time, the telescopic frame 5 under the connecting column 8 is extended and retracted inside the base 1, thereby improving the stability. When the telescopic frame 5 is pulled apart, the limit block 705 is released by the spring 704. The limit block 705 rebounds in the limit groove 6 in the telescopic frame 5. Since the limit block 705 is set in a trapezoidal shape, it will not be hindered when pulled out, but will be blocked by the limit when retracted. In this way, the deployment effect is completed and it is suitable for complex terrain conditions. After installation, people passing by around the coal mine can see the warning sign 10 in front of the support plate 9, which improves safety. At night, you only need to connect the external power supply and turn on the lamp 12 to illuminate the warning sign 10, so that people around can see the content clearly. In this way, the use process of the coal mine safety information display warning device is completed.

[0038] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
