Abstract

Automatic rotating hook. It consists of a hook mounted on cranes and bridge cranes that, by means of an engine and a series of assemblies and parts, the load can be rotated 380º to be able to position the load at the will of the operator operating the machine.

Description

Automatic rotating hook.

The present mention refers to a hook swivel mounted on cranes and overhead cranes, thanks to which notable improvements are achieved in relation to the hooks and known so far, whose improvements affect both work and to the safety of the people who handle this type of machinery.

Background

The hooks that mount the cranes are known and Crane bridges, which present great difficulty when it comes to position or move the load in a circular way (rotate it 360º) to operator's will to drive the machine, since the load remains suspended without any mechanism that can control your circular movement.

To avoid the movements that the existing hooks a new hook has been made whose Key features are as follows:

Positioning at will of the load by part of the operator who manages the crane since it can make a 360º turn of the load. These rotating movements are currently made manually, either by pushing the load an operator to modify the position or by means of ropes tied to the load by pulling they several operators depending on the weight of the load. By example, put a container in a car or put a beam in a determined site with position.

Another feature presented by the invention is safety, since the load that moves this type of machines is very high, the mere fact of being near or below these machines trying to correct the position, is a danger great, since you can detach all or part of the load, as has happened on numerous occasions.

Description of the invention

Mounting I, for hooks already manufactured

The automatic rotating hook for load positioning is of the type mounted by cranes and crane bridges, which has the peculiarity of having a wheel Toothed surrounding the neck of the hook, this cogwheel is driven by an engine that has an embedded drive pinion on its axis on the cogwheel when the engine runs the hook moves, begins to spin on itself (rotary movement). The engine is attached by means of a frame anchored to the assembly that holds the hook.

The movement of the hook will be done through controls located in the cabins of these machines.

The power can be by battery in the own motor or cable from the machine.

Assembly II, for your manufacturing

The automatic rotating hook for load positioning for realization in new cranes It has the peculiarity of carrying an engine inside the structure of the hook, which directly attacks the hook by means of the axis the motor. This axis is attached to the hook by means of a machining made in the central part of the hook head.

Food and handling as in the assembly I.

Brief description of the drawings

For a better understanding of how much is described Here are some drawings in which, so Only as an example are the two possible assemblies of the automatic rotating hook.

In said drawings Figure 1 is a view in side elevation of the hook assembly representing the Assembly I.

Figure 2, plan view, shows the wheel serrated in two parts that is welded to the neck of the hook (Assembly I).

Figure 3 shows a side elevation view of the hook assembly representing Assembly II.

Description of a preferred embodiment

Mounting I

The rotating automatic hook consists of a cogwheel (1) that is welded to the neck of the hook (first instance the cogwheel is divided into two pieces and with the machining the diameter of the hook neck; as the figure 2). This wheel is geared to a pinion (2), which is moved by an engine (3) that is housed on one side, by means of a frame (4), anchored to the assembly that supports the hook.

To facilitate the movement take a bearing on the neck of the hook (5).

Mounting II

Inside the hook assembly structure a motor (1a) attached to the assembly is mounted by means of an anchor (2nd).

This engine directly attacks the hook by middle of its axis (3a) the head of the mechanized hook (4a) so that between the axis and the movement can be performed.

A bearing (6a) is mounted on the shaft to facilitate rotational movement.

They will be independent of the object of the invention the materials used in the manufacture of the components of the automatic rotating hook, shapes and dimensions thereof and all the accessory details that may arise, provided and when they do not affect their essentiality.

Claims (3)

1. Automatic rotating hook, of the type that is mounted on a crane or bridge crane, characterized in that said hook incorporates a motor that can rotate on itself 360 degrees around the vertical axis of ascent and descent. 2. Automatic rotating hook of claim 1, characterized in that the vertical axis of raising and lowering is concentric to the head (4a) of the hook, and in addition to comprising the hook itself, a bearing (6a), a frame or anchor (2a ), and a motor (1a), so that the frame or anchor (2a) keeps the hook forming part of the crane or bridge crane and moving, raising or lowering the hook according to the crane or bridge crane, and being the crane bearing (6a) located on the head (4a) of the hook to allow its rotation while keeping it attached to the frame or anchor (2a), and the rotating movement of the hook being activated by the motor (1a) that is installed in the same frame or anchor (2a), and connected the axis (3a) of rotation of the motor (1a) to the head (4a) of the hook, in order to transmit the rotating movement to the hook. 3. Automatic rotating hook of claim 1, characterized in that the vertical axis of raising and lowering is concentric to the head of the hook, and also comprising the hook itself an annular toothed wheel (1), a bearing (5), a frame or anchor (4), and a motor (3), so that the frame or anchor (4) keeps the hook forming part of the crane or bridge crane and moving, raising or lowering the hook as the crane or bridge crane does , and the wheel (1) being concentric annular toothed to the neck of the hook and surrounding it and being welded to it, and with a bearing (5) on the neck of the hook to thus allow its rotation while keeping it attached to the frame or anchor (4), and the rotating movement of the hook being driven by the motor (3) being installed in the same frame or anchor (4), when the annular gear (1) is engaged meshed to a pinion (2) connected to the axis of rotation of
