Detailed Description
In order to clearly illustrate the technical features of the present solution, the following explains the present solution by a specific embodiment in combination with the accompanying drawings.
The first embodiment, shown in the attached figures 1-4, is a mining suspended belt pedestrian bridge, which comprises a belt conveyor bracket 5, a bridge middle plate 8, handrails 1 and two groups of ladder brackets 4, the ladder support 4 is obliquely arranged, the middle gap plate 8 is positioned at the upper part of the belt conveyor support 5, the two groups of ladder supports 4 are arranged at two ends of the intermediate plate 8, the handrails 1 are arranged at two sides of the intermediate plate 8, a pair of channel steel 2 is fixed on the top of the belt conveyor bracket 5, a spring 11 is fixed on the upper part of the channel steel 2, a guide sleeve 15 and a protective sleeve 9 are arranged outside the spring 11, the protective sleeve 9 is sleeved outside the upper end of the guide sleeve 15, the lower end of the guide sleeve 15 is fixed with the channel steel 2, the top end of the protection sleeve 9 is provided with a spring limiting plate 12, and the handrail 1 is fixed with the protection sleeve 9. The belt intermediate plate 8 is stressed to move up and down under the action of the tension of the spring 11. When the coal gangue conveyor is idle, the middle gap plate 8 is lifted by the tension of the spring 11, and the coal gangue passage is not affected; when people pass through, the spring 11 is stressed and tightened, the middle plate 8 in the gap bridge is lowered, and the people pass through; after passing through, the intermediate plate 8 automatically bounces and rises.
Be provided with guide bar 10 in the spring 11, the lower extreme of guide bar 10 with channel-section steel 2 is fixed, the upper end of guide bar 10 is passed spring limiting plate 12, be provided with on the spring limiting plate 12 with guide bar 10 assorted through-hole 13, the effect of guide bar 10 is the flexible direction of control spring 11 motion, avoids the phenomenon that the produced spring 11 became invalid of spring 11 wrench movement.
