Embodiment Construction
[0018] The present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.
[0019] Such as figure 1 As shown, the broken belt protection device for a double-four-link belt conveyor of the present invention includes a frame 1, a link rod 2, a lower arrester 3, an upper arrester 4 and a hydraulic cylinder 6. The frame 1 is Z-shaped, and the lower catch 3 is a connecting rod. Such as Figure 4 As shown, the upper capture 4 is Shape, its vertical side is the support leg 4-6 of going up catching, and its horizontal side 4-7 is established before catching block 4-5 and rear catching block 4-4. A hinge hole 4-1 is provided at the bottom of the leg 4-6 for hinged connection with the frame. A hinged hole 4-3 is provided at the top of the leg 4-6 to be hinged with the hydraulic rod 5 of the hydraulic cylinder 6. The middle part of supporting leg 4-6 is provided with hinged shaft 4-2, is used for catching hingedly with low...

The invention discloses a belt breakage protection device of a double-four-rod type belt conveyor. The belt breakage protection device of the double-four-rod type belt conveyor is characterized in that a set of double-rocker four-bar mechanism is formed by a machine frame, a connecting frame rod, a lower arresting block and an upper arresting block, the connecting frame rod is a driven part, the lower arresting rod is a connecting rod, the upper arresting rod is a driving rod, and a clamping mechanism of a double-four-connecting-rod broken belt protection device is formed by the double-rockerfour-bar mechanism; the machine frame, the upper arresting device and a hydraulic cylinder form a group of double-rocker four-bar mechanisms, is a driven rod, and the hydraulic rod is a connecting rod, the hydraulic cylinder body is a driving rod, the double-rocker four-bar mechanism serves as an executing mechanism of the double-four-connecting-rod broken belt protection device. The belt breakageprotection device is connected with the two four-bar mechanisms at the same time, so that the function of a linkage intermediary is achieved, the two four-bar mechanisms move at the same time and have good cooperative performance; and the four-bar linkage mechanism is simple in structure and prone to realize integral design and is mounted in a split mode, is independent from the belt conveyor andis convenient for regular detection and maintenance at the later stage of equipment.
Description
technical field [0001] The invention relates to a broken belt protection device for a belt conveyor, in particular to a broken belt protection device for a double-four-link belt conveyor, and is especially suitable for the broken belt protection of a coal belt conveyor. Background technique [0002] With the continuous development of mine mechanization, belt conveyors are widely used in mine uphill and downhill fields, and are constantly developing in the direction of long distances and large volumes, especially for coal uplifting belt conveyors with large inclination angles, long belts, and heavy loads. , prone to broken belt accidents, causing serious hazards, for example, damage to the idler bracket, causing the idler to fly horizontally; resulting in deformation of the belt frame and loose foundation; the uncontrolled conveyor belt during the slide will hurt pedestrians along the belt conveyor road And power cables, pipelines and other laying materials may cause friction...
