Description

Technical Field

[0001] The utility model relates to the technical field of hanging beam supporting equipment, in particular to a hanging beam supporting device for a steel crane. Background Art

[0002] Steel crane is a large mechanical equipment used for lifting heavy objects. It is commonly found in construction sites, docks, factories and other places that require a large number of items to be lifted. It can lift several tons or even tens of tons of weight.

[0003] A Chinese patent with announcement number CN214692924U discloses a support structure for a steel crane beam, which relates to the technical field of support structures. It includes a channel steel located on a support platform and a pad for fixing the crane beam. A first hinge for hingedly connecting the pad is provided on one side of the channel steel, and a trapezoidal block is provided on the other side of the channel steel. The end face of the trapezoidal block close to the pad is set as an inclined surface; the device pushes the pad to adjust its height through the second hinge, so that the pad can adjust the angle between the pad and the channel steel under the hinged action of the first hinge and the second hinge, thereby achieving the effect of adjusting the verticality of the crane beam.

[0004] The support structure of the above-mentioned steel crane beam has some problems during use. When the hoisted object is overloaded, it cannot be discovered in time, which makes the beam easily bear the pressure of overload and cause deformation or even damage, thereby shortening the service life of the beam. Therefore, a steel crane beam support device is proposed to solve the above problems. Utility Model Content

After the position of the hook is adjusted laterally to just above the hoisting object, when hoisting, the second motor is started to make the wire drum pay out the wire rope to move the hook down, and when the hook moves down to a suitable hoisting position, the hoisting object is hung on the hook, and the second motor is started again to make the wire drum reel in the wire rope, so that the hook drives the hoisting object to move up, thereby completing the transportation and hoisting operation of the hoisting object.

[0010] Preferably, the bottom of each base is fixedly connected to two mounting seats, and movable wheels are rotatably installed in the two mounting seats. When the device is used, the movable wheels are provided to facilitate moving the device to the desired position and also to transfer the hoisted objects to the desired position.
