Description

Anti-sway boom of crane

Technical field

The invention relates to the technical field of cranes, specifically to an anti-sway boom of a crane.

Background technique

The crane has the advantages of flexibility, easy operation, and high efficiency. However, when the crane is lifting the working object, the swing of the working object has always been a problem that needs to be solved. When the traditional crane is carrying out material transportation, the wire rope is usually lowered through the drum on the electric hoist to lift and transport the hoisted material. During the lifting process, when the heavy object is just lifted, since the heavy object has no supporting force in the horizontal direction, and the connection point between the rope and the hook that binds the heavy object is a non-horizontal contact surface, the heavy object will be torsionally unstable, causing serious problems. It will shake and collide with surrounding objects, causing some inevitable losses.

In addition, when the heavy object is lifted into the air, it is affected by the wind, causing the heavy object to sway, affecting the smooth lifting movement of the heavy object; when the wind is strong, the transmission components of the crane will shift left and right, causing the heavy object to move. The object swings greatly, seriously reducing the safety of lifting heavy objects.

The traveling wheel 26 is driven by the electric motor. The communication connection between the drive and the motor and the external controller is an existing technology and will not be described redundantly here.

Specifically, the driving motor 22 provides power to the rope winding frame 23, and the rope winding frame 23 winds up or releases the hanging rope. When the sensor detects that the swing amplitude of the sling is greater than the set value, it is fed back to the controller, and the controller sends a signal to control the electric push rod 254 to adjust the length, so that the angle of the originally parallel sling is enlarged to form an acute angle, and the angle is then hoisted. The force required to swing the rope increases, which can effectively reduce the swing amplitude of the hanging rope. At the same time, when the wind is too strong, the controller can work by controlling the hydraulic cylinder 27. The hydraulic cylinder 27 lifts the transmission assembly 2 through the base 28 to fix the position of the transmission assembly 2 on the traveling frame 1 and prevent the transmission assembly 2 from being moved. The traveling frame 1 swings greatly inside.

It should be noted that the height of the mounting seat 24 is lower than the height of the inner cavity of the traveling groove 12 , and a cushion layer that increases friction is provided on the upper end surface of the mounting seat 24 .

The meshing grooves engage so that the transmission component 2 has sufficient locking force when its position inside the traveling frame 1 is fixed, further ensuring the stability of the transmission component 2 when it is locked.

In this embodiment, the hanging rope passes between the two sets of rotation bearings 252, and the two sets of guide slide blocks 253 are respectively slidingly connected inside the guide grooves 13 on the adjacent sides of the two sets of support plates 11.

Among them, the guide slider 253 is slidably connected inside the guide groove 13, so that when the angle of the hanging rope is adjusted, the force of the hanging rope on the rotating bearing 252 will be converted into a horizontal force, thereby causing the electric push rod 254 to move. It is more stable when adjusting the position of the installation frame 251.

In this embodiment, as shown in Figures 6-8, the anti-swing component 3 includes a mounting bracket 31, the mounting bracket 31 is fixedly connected to a hook 33 through an adjusting component 32, the adjusting component 32 includes an upper fixed platform 321, The wire rope 325 and the lower fixed platform 326. The upper fixed platform 321 is rotatably connected to the lower fixed platform 326 through the connecting column 322.

A rotary connection groove is provided inside the lower fixed platform 326, and the limited seat 327 is rotatably connected inside the rotary connection groove. .

When the crane hangs heavy objects through the hook 33, a torsional swing will occur when the heavy object is lifted. At this time, the hook 33 causes several groups of wire ropes 325 to twist through the lower fixed platform 326. The wire ropes 325 themselves have recovery characteristics, so that after the wire ropes 325 are twisted, There will be a restoring force, so that the heavy object will tend to recover after swinging, thereby removing the swing force, further ensuring that the anti-swing component 3 quickly returns to stability after being lifted, and reducing the swing amplitude and swing time of the heavy object.

During the lifting process, Based on the torsional restoring force of several groups of steel wire ropes 325, the swing force when lifting the heavy object is removed to ensure that the heavy object quickly returns to stability after being lifted. After the heavy object is lifted to a predetermined height, the traveling wheel 26 is used to control the transmission assembly 2 to travel. When the frame 1 moves inside and the heavy object is swayed by the wind in mid-air, the electric push rod 254 is controlled by the controller to adjust the position of the installation frame 251, and the angle of the originally parallel sling is enlarged to form an acute angle to increase the resistance of the sling to swing. force to keep the heavy object stable in the air. When detecting that the wind force exceeds the threshold, the controller can work by controlling the hydraulic cylinder 27.
