The invention relates to a portable type self-steady gap bridge. The portable type self-steady gap bridge comprises a bridge plate, support legs, support rods, telescopic rods, hydraulic cylinders, glue boxes and control boxes, wherein the four support legs are hinged to the four corners of the bridge plate; one end of the corresponding support rod is hinged to the middle of the bottom end of thebridge plate while the other ends of the support rods are buckled to the support legs; the telescopic rods are connected to the bottoms of the support legs in an inserting manner; the outside diameters of the telescopic rods are identical to the inside diameters of the support legs; the hydraulic cylinders are fixedly connected to the sides of the bottoms of the support legs; the output ends of the hydraulic cylinders are fixedly connected with the telescopic rods; the glue boxes are fixedly connected to the other sides of the bottoms of the support legs and communicate with the inner cavitiesof the support legs; the interiors of the glue boxes are filled with non-Newtonian fluids; the non-Newtonia fluids is propped against the top end faces of the telescopic rods; and the control boxes are fixedly connected to the bottoms of the bridge plate and are connected with the hydraulic cylinders through pipelines. The portable type self-steady gap bridge disclosed by the invention has the advantages that the gap bridge can be erected quickly on a transmission belt, and the gap bridge can still keep steady on a bumpy ground.
Description
technical field [0001] The invention relates to the technical field of mine appliances, in particular to a portable self-stabilizing belt bridge. Background technique [0002] In order to ensure that the oxygen content in the mine is sufficient, it is necessary to set up an air duct on the top of the mine to blow air in the mine. Some of the air ducts need to pass through the belt for transporting mineral materials. When it is necessary to work on the belt, it is necessary to contact the belt driver in advance Communication stops the operation of the belt conveyor, and personnel stand on the belt rack to carry out operations, which not only affects the normal production of the mining and excavation working face, but also has great potential safety hazards when personnel stand on the belt rack to work. [0003] Therefore, in view of the above deficiencies, a portable self-stabilizing belt crossing bridge needs to be provided. Contents of the invention [0004] (1) Technica...
