DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0021] In this embodiment, refer to Figs. 1-3 A portable early warning auxiliary device, comprising a fixed support 1, the bottom of the fixed support 1 is provided with a mobile wheel, which is convenient to move and can provide portability. The fixed support 1 is a U-shaped structure, and the front and rear of the fixed support 1 are provided with openings. The top of the fixed support 1 is provided with a protective cover top 14. The front and rear of the fixed support 1 are provided with openings, which facilitates the spread of the alarm sound. The protective cover top 14 provides protection for the early warning device built into the fixed support 1. In addition, the front and rear of the fixed support 1 are through, so that when the early warning device is maintained and replaced in the later period, the fixed support 1 does not need to be disassembled, and the maintenance work can be completed, which is relatively convenient to operate and reduces the operation difficulty for the maintenance personnel.

[0022] Rotary shafts 2 are arranged at the corresponding positions of the inner walls of the fixed support 1, and the rotary shafts 2 on the two sides are aligned and are provided with jackets 3, respectively. The mounting plate 4 is clamped by the jackets 3 on the two sides, and the jackets 3 on the two sides are consistent in structure. The jackets 3 are internally provided with insertion cavities for the insertion of the mounting plate 4. The mounting plate 4 can be used to connect the jackets 3 on the two sides, so as to ensure that the mounting plate 4 is in a rotatable state.

[0023] The mounting plate 4 is connected with the mounting table 6 through the air cylinder 5. Here, the output end of the air cylinder 5 is provided with a pneumatic rod 16, the pneumatic rod 16 penetrates the plate surface of the mounting plate 4 and is connected with the mounting table 6 on the other side of the mounting plate 4. In addition, a plurality of same through holes are formed in the plate surface of the mounting plate 4, and each through hole is arranged with a guide sliding cylinder 7. The guide sliding cylinders 7 are respectively slidably connected with sliding rods 8, and the ends of the sliding rods 8 away from the guide sliding cylinders 7 are fixedly connected with the mounting table 6. The sliding rods 8 and the early warning device main body 9 are arranged on the two sides of the mounting table 6, respectively.

[0024] The air cylinder 5 is used to control the movement of the mounting table 6 towards or away from the mounting plate 4, and the plurality of sliding rods 8 can ensure the stability of the mounting table 6 during movement. The mounting table 6 and the mounting plate 4 are always arranged in parallel.

[0025] The early warning device body 9 is installed on the installation platform 6, and the early warning device body 9 on the installation platform 6 can rotate because the installation platform 6 is kept parallel with the installation plate 4 and the installation plate 4 can rotate. In actual application, the early warning device body 9 can spread the alarm sound within a certain range of pitch angle, and the alarm sound is not spread along a fixed angle, which is beneficial to spread the alarm sound more widely and play a warning role.

[0026] The hydraulic cylinder 10 is rotatably installed on one side of the fixed support 1 through a fixed shaft 15, the front end of a piston rod 11 arranged at the top output end of the hydraulic cylinder 10 is provided with a connecting shaft 13, the outer wall of the fixed support 1 is rotatably connected with a rotating seat 12 above the hydraulic cylinder 10, and the distal end of the rotating seat 12 is rotatably connected with the connecting shaft 13 arranged at the front end of the piston rod 11 below. Finally, it should be pointed out that the rotating seat 12 and the rotary shaft 2 in the fixed support 1 are coaxially rotatable through a straight shaft. The hydraulic cylinder 10 is used to control the rotation of the rotating seat 12, and the rotating seat 12 rotates synchronously with the rotary shaft 2 in the fixed support 1, so that the turning angle of the early warning device body 9 can be controlled through the hydraulic cylinder 10, thereby achieving the purpose of spreading the alarm within a wide angle range.

[0027] In use, the hydraulic cylinder 10 can control the turning angle of the early warning device body 9; in maintenance, the hydraulic cylinder 10 can control the early warning device body 9 to directly rotate to a flat state, and at the same time, the cylinder 5 can also control the early warning device body 9 to advance forward until the early warning device body 9 is stretched out of the fixed support 1, which is convenient for the maintenance personnel to maintain.

[0028] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
