Description

Technical Field

[0001] The utility model relates to the technical field of double-beam overhead cranes, and in particular to a double-beam overhead crane with a steel wire rope anti-sway mechanism. Background Art

[0002] Double-beam crane generally refers to double-beam overhead crane, which is generally composed of three parts: mechanical, electrical and metal structure. The crane looks like a single-span flat bridge with two ends supported on two parallel overhead rails. Double-beam cranes are widely used in indoor and outdoor industrial and mining enterprises, steel and chemical industry, railway transportation, port terminals, logistics turnover and other departments and places.

[0003] The patent specification with announcement number CN219885502U discloses a double-beam overhead crane wire rope anti-sway device. By using a winch, a wire rope and a multi-layer telescopic cylinder to cooperate, the stability of the wire rope during movement is ensured. The multi-layer telescopic cylinder will not swing, so that the wire rope inside it will not swing during movement. On the basis of existing technology, artificial safety accidents are avoided, production safety hazards are reduced, and production efficiency is improved. The device has a simple structure and low cost.

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: during the use of the above device, its wire rope still has a certain range of movement and can still move in the inner diameter of its multi-layer telescopic cylinder. When the hook end of the wire rope shakes, it will still cause the wire rope to swing in the inner diameter of the multi-layer telescopic cylinder. Therefore, further improvement is needed. Utility Model Content

[0005] The utility model provides a double-beam overhead crane with a steel wire rope anti-sway mechanism, which solves the problem in the related art that it is inconvenient to limit the steel wire rope to prevent the steel wire rope from swinging.

[0006] The technical solution of the utility model is as follows:

[0007] A double-beam overhead crane with a wire rope anti-sway mechanism comprises a double-beam overhead crane body, a through groove is penetrated through the upper end of the double-beam overhead crane body, a rotating rod is rotatably connected to the inner wall of the through groove, an anti-sway assembly is arranged on the outer surface of the double-beam overhead crane body, a first circular ring is slidably connected to the inner wall of the through groove, a connecting rod is fixedly connected to the upper end of the first circular ring, a second circular ring is fixedly connected to the upper end of the connecting rod, inflatable limit pads are evenly arranged on the inner wall of the second circular ring, and an inflatable tube is arranged on the outer surface of the second circular ring.

[0008] Preferably, a circular groove is opened on the inner wall of the through groove, the two ends of the rotating rod are rotatably connected inside the circular groove, the rotating rod is externally connected to a motor, and a steel wire rope is fixedly connected to the outer surface of the rotating rod.

[0009] Preferably, the anti-sway assembly comprises a sliding groove provided at the upper end of the double-beam overhead crane body, and a plurality of groups of limiting grooves are evenly provided at the lower end of the double-beam overhead crane body.

[0010] Preferably, the limiting groove is communicated with the sliding groove, and a moving groove is provided on the inner wall of the through groove.

[0011] Preferably, the movable groove is communicated with the sliding groove, and support blocks are fixedly connected to both sides of the first circular ring.

[0013] Preferably, the notch is connected to the limiting groove in correspondence, a limiting rod is movably provided on one side of the double-beam overhead crane body, and the limiting rod passes through the sliding groove, the notch and the limiting groove in sequence.

[0014] Preferably, the inflation tube passes through the interior of the second ring and is connected with the inflation limiting pad.

[0015] The working principle and beneficial effects of the utility model are:

[0016] 1. The utility model allows the steel wire rope to pass through the first and second rings in sequence, at which time the hook end of the steel wire rope is located below the second ring. At this time, the steel wire rope can be limited by the joint action of the first ring, the connecting rod and the second ring to prevent the steel wire rope from passing through the first and second rings. The inflatable limiting pad is inflated and deflated through the inflatable tube to control the expansion of the inflatable limiting pad so that the inflatable limiting pad inside the second ring touches and squeezes the steel wire rope. At this time, the moving range of the steel wire rope is further reduced under the action of the inflatable limiting pad, that is, the steel wire rope is further limited to prevent it from swinging, thereby solving the problem of being inconvenient to limit the steel wire rope to prevent it from swinging.

[0017] 2. The utility model allows the worker to pull the limit rod to separate from the limit groove when it is necessary to change the position of the hook end of the wire rope below the double-beam crane body, and then the worker pushes the first ring to drive the support block to move along the inside of the movable groove. After the first ring is moved to a suitable required position, and the notch and the limit groove are connected to each other, the worker can then re-pass the limit rod through the inside of the sliding groove, the notch and the limit groove in sequence. At this time, under the action of the limit rod, the notch and the limit groove, the first ring can be prevented from moving inside the movable groove again. BRIEF DESCRIPTION OF THE DRAWINGS
