Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0025] First embodiment:

[0026] like Figure 1-5 As shown, the safety warning sign for mine construction provided by this utility model includes: a main body 100 and a fixing mechanism 200. The main body 100 is located above the fixing mechanism 200 and is the information display part for installing the warning sign. The lower end of the fixing mechanism 200 is stably connected to the ground, and the upper end is connected to the main body 100. Specifically, the main body 100 includes a first sleeve 101, which is rod-shaped. A mounting frame 102 is fixedly provided at the upper end of the first sleeve 101. The mounting frame 102 is used to install the content of the warning sign. The warning sign can be fixed to the mounting frame 102 using self-tapping screws. The fixing mechanism 200 includes a spiral drill bit 201, and the upper end of the spiral drill bit 201 is fixed... A threaded rod 202 is fixedly installed, and a cap 203 is provided at the upper end of the threaded rod 202. A hexagonal cap 203 can be used. When burying warning signs, a bit that matches the specification of the cap 203 is installed at the end of the shaft of a small drilling rig or other tool. After starting the drilling rig, the shaft drives the auger drill bit 201 to rotate and enter the ground. If the soil at the construction site is soft, the auger drill bit 201 can also be driven into the ground manually. A baffle 206 is provided around the threaded rod 202. When the baffle 206 contacts the ground, the drilling rig is turned off to stop further driving. The first sleeve 101 has an internal thread that matches the external thread of the threaded rod 202. Then, the first sleeve 101 is spirally rotated into the threaded rod 202, and the installation is completed.

[0027] By setting the auger drill bit 201 and the threaded rod 202 to provide stable support for the installation of the warning sign, compared with the existing method of carrying the warning sign by a trolley, the first sleeve 101 and the threaded rod 202 are lighter and easier to carry into the construction site, and can be quickly installed on site. At the same time, they can be disassembled for the next use after use.

[0028] By setting the threaded rod 202 and the first sleeve 101 adapted to the threaded rod 202, the total length of the first sleeve 101 and the threaded rod 202 can be adjusted, thereby changing the overall height of the device to suit more complex construction environments.

[0029] Second embodiment:

[0030] like Figure 4-5 As shown, both the threaded rod 202 and the auger drill bit 201 have cavities. The auger drill bit 201 has holes on its surface that communicate with the internal cavities. The cap 203 at the upper end of the threaded rod 202 is threadedly connected to the threaded rod 202 and can be unscrewed from the threaded rod 202. When the soil at the construction site is relatively loose or there are frequent strong winds, in order to ensure the stability of the connection between the fixing mechanism 200 and the ground, cement grout can be injected under high pressure from the upper end of the threaded rod 202 after the auger drill bit 201 is driven into the ground. The cement grout is discharged from the holes on the surface of the auger drill bit 201 and seeps into the nearby soil. After the cement grout hardens, it can enhance the strength of the soil near the auger drill bit 201 and make the connection between the device and the ground more stable.

[0031] Third embodiment:

[0032] like Figure 4-5 As shown, a second sleeve 204 is provided at the upper end of the baffle 206. The second sleeve 204 has threads on both the inside and outside. The lower end is fixedly connected to the baffle 206. The two are in an inverted T shape. The second sleeve 204 is fixedly installed on the threaded rod 202. A cover plate 207 and a nut 205 are sleeved around the second sleeve 204. The nut 205 is threaded to the outer wall of the second sleeve 204. The nut 205 is located at the upper end of the cover plate 207. The lower surface of the cover plate 207 has a groove of the same specification as the baffle 206. After the auger drill bit 201 stops rotating, the nut 205 is rotated and moves downward. At the same time, the nut 205 pushes the cover plate 207 downward to the ground and generates a certain pressure on the ground.

[0033] Because the device is rod-shaped with a large slenderness ratio, it is prone to overturning under the horizontal push of wind load. By setting a cover plate 207 and fixing it to the ground, the connection stability between the device and the ground can be increased.

[0034] Fourth embodiment:

[0035] like Figure 3 , Figure 5As shown, a socket 105 is slidably provided on the outer wall of the first sleeve 101. The inner wall of the socket 105 is provided with a strip-shaped protrusion. A groove 110 is provided on the outer wall of the first sleeve 101 at a position corresponding to the strip-shaped protrusion. The protrusion and the groove 110 are adapted to each other. The socket 105 is installed on the back of the warning sign. After the warning sign is installed on the first sleeve 101, the protrusion is located in the groove 110. The cooperation between the protrusion and the groove 110 can constrain the rotation of the warning sign under wind load in any direction.

[0036] Fifth embodiment:

[0037] like Figure 2 As shown, the mounting bracket 102 has an adsorption strip 104 on one side, which can attract the warning sign. If the warning sign is made of thin steel plate, the adsorption strip 104 can be made of strong magnet as the material for adsorbing and fixing the warning sign. The upper and lower ends of the side of the mounting bracket 102 are also provided with baffles 103, and the warning sign can be inserted between the baffles 103 and the mounting bracket 102.

[0038] The warning sign is fixed to the mounting frame 102 by setting the baffle 103. In addition, the baffle 103 is set at the upper and lower ends of the mounting frame 102. Warning signs of different shapes can be stuck between the baffle 103 and the mounting frame 102. As the construction environment changes, the warning signs on the device can be replaced accordingly without replacing the entire device.

[0039] When installing warning signs, a small drilling rig or other tools are used to rotate the auger bit 201 and drive it into the ground. If the soil at the construction site is soft, the auger bit 201 can also be driven into the ground manually. The threaded rod 202 is equipped with a baffle 206. When the baffle 206 contacts the ground, further driving is stopped. The first sleeve 101 is provided with an internal thread and is adapted to the external thread of the threaded rod 202. Then, the first sleeve 101 is spirally rotated into the threaded rod 202, and the installation is completed.

[0040] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
