Description

Bridge crane lifting hook with adjustable Technical Field The utility model relates to the technical field of crane lifting appliances, in particular to an adjustable bridge crane lifting hook. Background The bridge crane is hoisting equipment for hoisting materials in workshops, warehouses and stock yards. The bridge-like shape is obtained by sitting on tall concrete columns or metal supports at both ends. The bridge frame of the bridge crane longitudinally runs along the tracks paved on the two side high frames, so that the space below the bridge frame can be fully utilized to hoist materials, and the bridge frame is not blocked by ground equipment. The hoisting machine has the advantages of being the hoisting machine with the widest application range and the largest number. At present, the lifting hook of the bridge crane is suspended by using a lifting steel wire rope, and an elastic baffle plate is arranged in the lifting hook to achieve the effect of preventing unhooking. When the lifting hook hooks the lifting ring of the heavy object or the binding steel wire rope, the lifting ring or the steel wire rope is easy to displace in the hooking and unhooking hook, and the safety tongue piece is easy to be crashed, so that the risk of falling the heavy object exists. Disclosure of utility model The utility model aims to provide an adjustable bridge crane lifting hook which is used for solving the problem that the lifting hook of the existing bridge crane is poor in anti-falling effect. The technical scheme is that the adjustable bridge crane lifting hook comprises a connecting piece connected with a lifting steel wire rope and a hook connected to the bottom of the connecting piece, wherein the inner cambered surface of an arc-shaped block is in sliding fit with the outer cambered surface of the hook, a through hole is formed in the middle of the arc-shaped block, the anti-falling rod comprises a rod piece movably sleeved with the through hole, a threaded column fixedly butted to one end of the rod piece and a rotating wheel fixedly arranged at the other end of the rod piece, an inner cambered surface sliding groove is formed in the position, located on the lower side of an opening, of the inner cambered surface of the hook, a sphere is movably clamped in the inner cambered surface sliding groove, a threaded hole in threaded sleeve fit with the threaded column is formed in the middle of the sphere, a sideslip groove opposite to the inner cambered surface sliding groove is formed in the other side of the hook, and the rod piece is in sliding clamping connection with the sideslip groove. Preferably, the connecting piece comprises a shell, grooved wheels rotatably arranged on two sides of the middle part of the inner cavity of the shell, and shaft bodies sleeved on the front wall and the rear wall of the middle part of the bottom end of the shell respectively at the front end and the rear end of the grooved wheels, and the tops of the hooks are sleeved on the shaft bodies. Preferably, the hook comprises an arc-shaped piece, a ring body sleeved on the shaft body and a rotating column vertically connected between the top end of the arc-shaped piece and the bottom of the ring body, the intrados sliding groove is formed in the position, located on the lower side of the opening, of the intrados of the arc-shaped piece, and the sideslip groove is formed in the other side of the arc-shaped piece and in the position opposite to the intrados sliding groove. Preferably, the arc piece outer cambered surface is located the position of sideslip groove front and back side is equipped with profile of tooth arch first respectively, the arc piece inner cambered surface be equipped with profile of tooth protruding second of profile of tooth protruding joint matching. Preferably, the bottom of the rotating column is fixedly connected with the top end of the arc-shaped piece, and the top end of the rotating column is rotatably sleeved with the bottom of the ring body. Compared with the prior art, the utility model has the beneficial effects that: The adjustable bridge crane lifting hook disclosed by the utility model is not only convenient for carrying out the operation of hanging the lifting hook on a heavy object, but also can be reliably locked so as to enhance the anti-falling performance of the bridge crane lifting hook.
