As an important equipment for mine engineering machinery, it is of great significance to monitor and manage a scraper loader; the monitor is usually installed on the top of the scraper loader. When the scraper loader works underground in the mine, different working scenarios require adjustment to different angles to adapt to complex on-site monitoring. The monitoring brackets in the prior art are fixedly connected by bolts. When the angle needs to be adjusted, the bolts need to be disassembled for adjustment, which is time-consuming and laborious, and it is difficult to flexibly adjust the camera at multiple angles.

A plurality of positioning holes matching the positioning pin assembly are evenly distributed in the circumferential direction on the base. A gantry is connected to the rotating ring. A monitoring head is rotatably connected to the gantry. A braking assembly is further arranged on the gantry. The braking assembly is used to adjust the rotation angle of the monitoring head and brake the monitoring head.

[0005] Further, the positioning pin assembly includes a stud installed on the rotating ring. A through hole is coaxially opened in the stud. A positioning pin is slidably connected in the through hole. A through groove is opened in the stud. A limiting plate is slidably connected in the through groove. The limiting plate is fixedly installed on the positioning pin. A first compression spring is installed in the through groove. The first compression spring applies an inward elastic force to the limiting plate.

[0006] Further, a threaded through hole is opened on the rotating ring. The stud is screwed into the threaded through hole.

[0007] Further, the end of the positioning pin is hemispherical.

[0008] Further, an annular track groove matching the position of the positioning pin is opened on the base.

[0009] Further, the positioning pin is made of high manganese steel.

[0010] Further, the braking assembly includes an upper limit plate and a lower limit plate connected to the gantry. A second compression spring is installed between the upper limit plate and the monitoring head, and an adjusting screw is screwed on the lower limit plate.

[0011] Advantages of the present utility model: The structure of the present utility model is simple. An elastic positioning pin assembly is designed to achieve 360-degree horizontal adjustment of the camera without disassembling bolts, with quick and convenient operation. At the same time, a braking assembly is designed to achieve vertical rotation adjustment of the camera, making it flexible and variable in use, and worthy of wide promotion and use.

Specific embodiments:

[0016] As Figure 1 and Figure 2 shown, a multi-degree-of-freedom monitoring bracket device for a scraper includes a base 1. A rotating ring 3 is rotatably connected to the outer wall of the base 1. A positioning pin assembly is installed on the rotating ring 3. A plurality of positioning holes 4 matching the positioning pin assembly are evenly distributed in the circumferential direction on the base 1. A gantry 9 is connected to the rotating ring 3. A monitoring head 14 is rotatably connected to the gantry 9. A braking assembly is further provided on the gantry 9. The braking assembly is used to adjust the rotation angle of the monitoring head 14 and brake the monitoring head 14.

[0017] As Figure 2 and Figure 3As shown, the positioning pin assembly includes a stud 5 installed on the rotating ring 3. A through hole is coaxially provided in the stud 5. A positioning pin 6 is slidably connected in the through hole. A through groove is provided in the stud 5. A limiting plate 7 is slidably connected in the through groove. The limiting plate 7 is fixedly installed on the positioning pin 6. A first compression spring 8 is installed in the through groove. The first compression spring 8 applies an inward elastic force to the limiting plate 7. To facilitate disassembly and adjustment of the tightness of the positioning pin 6, a threaded through hole is provided in the rotating ring 3, and the stud 5 is screwed into the threaded through hole. The end of the positioning pin 6 is hemispherical. An annular track groove 2 matching the position of the positioning pin 6 is provided on the base 1 to facilitate the movement of the positioning pin 6 in the track groove 2. To improve the wear resistance of the positioning pin 6, the positioning pin 6 is made of high manganese steel.
