Description
Technical Field
[0001] The utility model relates to the field of drilling equipment in the mining industry, in particular to a drilling rig propulsion beam. Background Art
[0002] The lifting and propulsion beam of the existing drilling rig is composed of the drilling rig propulsion system, the head support rod device, the dust cover cylinder, the hose reel assembly, the slewing head installation assembly, etc., all of which are connected by bolts. Among them, the lifting and propulsion system is propelled by the hydraulic cylinder and the wire rope. The lifting and propulsion beam is made of cast aluminum alloy. The aluminum alloy beam has a double bottom structure, which is light and flexible. The aluminum alloy propulsion beam can swing forward and backward and left and right very flexibly.
[0003] In order to reduce the overall weight of the equipment, the lifting and propulsion beam of the drilling rig is designed with a cast aluminum alloy material with relatively light weight and relatively high strength. The wire rope pulley under the lifting and propulsion beam is installed on the aluminum web (wall thickness 10mm) of the lifting and propulsion beam. The guide rope pulley seat is supported on one side of the lifting and propulsion beam and is subjected to the lifting and pushing dynamic loads. Under frequent alternating loads and stresses, the aluminum alloy causes fatigue tearing and deformation. The guide rope pulley is completely separated from the lifting and propulsion beam, which in severe cases causes the lifting and propulsion beam to be scrapped as a whole, affecting the normal operation of the drilling rig.
[0004] Therefore, how to prevent the aluminum web of the drilling rig propulsion beam from being easily damaged, and thereby achieve long-term stable and efficient operation of the drilling rig to ensure the smooth progress of production, is a technical problem that technical personnel in this field currently need to solve.
