[0002] In today's pursuit of safe production, comprehensive improvement of safety management and control, and the construction of inherently safe enterprises, industries such as mineral processing, metallurgy, construction, and chemicals are striving to improve safety assurance levels, reduce safety risks in production operations, avoid safety accidents, enhance enterprise safety production levels, and seek safe and stable development. Therefore, higher requirements have been placed on the safety protection of various equipment and facilities. The safety protection of equipment and facilities and inherently safe production have become important criteria for measuring the high-quality development of enterprises. In the mineral processing field, belt conveyors are indispensable and important production equipment. A large proportion of belt conveyors are open-air, and ladders are often erected to facilitate personnel access during system start-up and maintenance.

[0003] The existing patent number CN210914036U discloses a safety protection device for an open-air belt conveyor bridge ladder, which solves the problems existing in the open-air belt conveyor bridge ladder in the prior art. The device includes supporting columns set around the top of the bridge ladder corridor, with corridor railings fixed between the supporting columns. A transverse grab guard device is provided on the outside of the bridge ladder at the bottom of the bridge ladder corridor, and a pedestrian distance is left between the transverse grab guard device and the bridge ladder.

[0004] The above solution facilitates worker access and ensures that if a worker accidentally slips off the ladder, they can quickly grab the horizontal handrail safety device. While this guarantees worker safety, installing the device on the slip-off ladder is very cumbersome and time-consuming. Furthermore, the height is not adjustable after installation, posing a safety hazard to taller workers due to the low safety height. Utility Model Content

The locking rods 114 are locked into any round hole 117 under the limit of the slide groove 115, and the protective height of the lifting plate 116 can be adjusted.

[0026] like Figures 1 to 4As shown, a threaded rod 104 is movably embedded inside the base plate 103. One end of the threaded rod 104 is rotatably connected to a movable strip 105 via a bearing. Two sliding grooves 106 are formed on the outer surface of the base plate 103. The movable strip 105 is slidably connected inside the two sliding grooves 106. A fixing strip 107 is fixedly connected to the top of the outer surface of the base plate 103. A protruding plate 102 is fixedly connected to the outer surface of the conveyor body 101. Rotating the threaded rod 104 causes the movable strip 105 to move towards the fixing strip 107 inside the sliding groove 106. After moving, the movable strip 105 and the fixing strip 107 can clamp and fix the protruding plate 102. At this time, the base plate 103 is installed on one side of the conveyor body 101.
