Description

Technical Field

[0001] The invention relates to the technical field of cranes, in particular to an anti-sway boom of a crane. Background Art

[0002] Cranes have the advantages of flexibility, easy operation and high efficiency. However, when cranes are lifting objects, the swing of the objects has always been a problem that needs to be solved. Traditional cranes usually lift and transport materials by lowering wire ropes through the drum on the electric hoist. During the lifting process, when the heavy objects are just lifted, there is no horizontal support for the heavy objects, and the connection point between the ropes binding the heavy objects and the hooks is a non-horizontal contact surface, which makes the heavy objects torsional unstable. In severe cases, they will shake and collide with surrounding objects, causing some inevitable losses.

[0003] In addition, when heavy objects are hoisted into the air, they are affected by the wind and cause them to sway, affecting the smooth movement of the lifting. When the wind is strong, the transmission components of the crane will shift left and right, causing the heavy objects to swing greatly, seriously reducing the safety of lifting the heavy objects.

[0037] like Figure 1-5 As shown, this embodiment provides an anti-sway boom of a crane, comprising a traveling frame 1, a transmission assembly 2 and an anti-sway assembly 3, wherein the transmission assembly 2 is installed inside the traveling frame 1, the anti-sway assembly 3 is movably installed at the bottom of the transmission assembly 2, and the transmission assembly 2 is used to transmit the anti-sway assembly 3 laterally;

[0038] The traveling frame 1 includes two groups of support plates 11, which are fixedly connected by a fixing rod and arranged in parallel. The adjacent sides of the two groups of support plates 11 are provided with traveling grooves 12 and guide grooves 13 in sequence from top to bottom.

[0039] The transmission assembly 2 includes a mounting platform 21, a mounting seat 24 and an adjustment mechanism 25. Two sets of fixed plates are fixedly connected to the upper end surface of the mounting platform 21 at intervals. A driving motor 22 and a rope winding frame 23 are installed on the adjacent sides of the two sets of fixed plates. There are two sets of mounting seats 24, which are respectively fixedly connected to both sides of the mounting platform 21. A plurality of travel wheels 26 are installed at the bottom of the mounting seat 24. A set of hydraulic cylinders 27 are installed on both sides of the lower end surface of the mounting seat 24. The output end of the hydraulic cylinder 27 is fixedly connected to the base 28. The adjustment mechanism 25 is fixedly connected to the lower end surface of the mounting platform 21.

[0040] The adjusting mechanism 25 includes a mounting frame 251, an electric push rod 254 and a fixed seat 255. The electric push rod 254 is mounted on the fixed seat 255. The output end of the electric push rod 254 is fixedly connected to the front end surface of the mounting frame 251. Two groups of rotating bearings 252 are symmetrically installed inside the mounting frame 251. A group of guide sliders 253 are fixedly connected on both sides of the mounting frame 251.

[0041] Furthermore, one end of the driving motor 22 is rotatably mounted with the rope winding frame 23 via a speed reducer, and the driving motor 22 is used to drive the rope winding frame 23 to rotate.

[0042] Furthermore, a sensor is installed on the upper end surface of the mounting platform 21 , and a suspension rope is hingedly connected to the outside of the sensor. The suspension rope passes through the anti-sway component 3 and is wound around the surface of the rope winding frame 23 .

[0043] Among them, the sensor is specifically a wind speed sensor, the sensor is electrically connected to the external controller, and the output end of the external controller is also communicated with the drive motor 22, the traveling wheel 26, the hydraulic cylinder 27 and the electric push rod 254. The traveling wheel 26 is driven by the motor, and the motor is communicated with the external controller. This is a prior art and will not be described in detail here.

[0044] Specifically, the driving motor 22 provides power to the rope reel 23, and the rope reel 23 reels or releases the rope. When the sensor detects that the swing amplitude of the rope 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 ropes is enlarged to form an acute angle. After the angle is formed, the force required for the rope to swing increases, which can effectively reduce the swing amplitude of the rope. At the same time, in weather with strong winds, the controller can control the hydraulic cylinder 27 to work, and the hydraulic cylinder 27 lifts the transmission assembly 2 through the base 28, so that the position of the transmission assembly 2 on the traveling frame 1 is fixed, preventing the transmission assembly 2 from swinging significantly inside the traveling frame 1.

[0045] It should be noted that the height of the mounting seat 24 is lower than the height of the inner cavity of the running groove 12 , and a cushion layer for increasing friction is also provided on the upper end surface of the mounting seat 24 .

[0046] Furthermore, a group of support grooves are provided on both sides of the lower end surface of the traveling wheel 26, and the support grooves are used to receive the base 28. A plurality of groups of meshing teeth are provided at the bottom of the base 28, and the hydraulic cylinder 27 is installed inside the support grooves.

[0047] Furthermore, the mounting seat 24 is slidably connected inside the running groove 12, and a plurality of groups of meshing grooves adapted for meshing are provided at the bottom of the running groove 12.

[0048] Specifically, the hydraulic cylinder 27 pushes the base 28 out of the support groove, and then lifts the transmission assembly 2. At this time, the upper end surface of the mounting seat 24 contacts the top of the traveling groove 12, and the base 28 engages with the engaging groove at the bottom of the traveling groove 12 through the engaging teeth, so that the transmission assembly 2 has sufficient locking force when its position inside the traveling frame 1 is fixed, further ensuring the stability of the transmission assembly 2 when it is locked.

[0049] In this embodiment, the suspension rope passes through between the two sets of rotating bearings 252 , and the two sets of guide sliding blocks 253 are respectively slidably connected to the inside of the guide grooves 13 on the adjacent sides of the two sets of support plates 11 .

[0050] Among them, the guide slider 253 is slidably connected inside the guide groove 13, so that when the angle of the suspension rope is adjusted, the force of the suspension rope on the rotating bearing 252 will be converted into a horizontal force, thereby making the electric push rod 254 more stable when adjusting the position of the mounting frame 251.

[0051] In this embodiment, if Figure 6-8 As shown, the anti-sway component 3 includes a mounting frame 31, and the mounting frame 31 is fixedly connected to a hook 33 through an adjusting component 32. The adjusting component 32 includes an upper fixed platform 321, a steel wire rope 325 and a lower fixed platform 326. The upper fixed platform 321 is rotatably connected to the lower fixed platform 326 through a connecting column 322. The connecting column 322 is fixedly connected to a diffusion plate 323 on the outside. The diffusion plate 323 is symmetrically provided with a plurality of mounting grooves 324 on the outside. The two ends of the steel wire rope 325 are fixedly connected to the adjacent sides of the upper fixed platform 321 and the lower fixed platform 326.

[0052] Furthermore, the number of the steel wire ropes 325 is the same as the number of the mounting grooves 324 , and the steel wire ropes 325 pass through the inside of the mounting grooves 324 .

[0053] Furthermore, the vertical distances from the connection points of the wire rope 325 on the upper fixed platform 321 and the lower fixed platform 326 to the axis of the connecting column 322 are equal, and the distance from the installation groove 324 to the axis of the connecting column 322 is greater than the distance from the connection point of the wire rope 325 and the lower fixed platform 326 to the axis of the connecting column 322.

[0054] The point where the steel wire rope 325 passes through the installation groove 324 will bulge outward, so that the steel wire rope 325 is bent into an arc.

[0055] Furthermore, one end of the connecting column 322 is fixedly connected to the lower end surface of the upper fixed platform 321, and one end of the connecting column 322 is fixedly connected to the limiting seat 327. A rotating connecting groove is opened inside the lower fixed platform 326, and the limiting seat 327 is rotatably connected inside the rotating connecting groove.

[0056] When the crane hangs a heavy object through the hook 33, the heavy object will twist and swing when it is lifted. At this time, the hook 33 twists several groups of steel wire ropes 325 through the lower fixed platform 326. The steel wire ropes 325 themselves have recovery characteristics, so that the steel wire ropes 325 will have a recovery force after being twisted, and then the heavy object will tend to recover after swinging, and then the swinging force will be removed, further ensuring that the anti-swing component 3 quickly returns to stability after lifting, reducing the swing amplitude and swing time of the heavy object.

[0057] Working principle: When lifting a heavy object, the present invention hangs the heavy object through the hook 33, and then drives the rope reel 23 through the driving motor 22 to reel in the rope to perform the lifting and hoisting operation of the heavy object. During the lifting process, based on the torsional restoring force of several groups of steel wire ropes 325, the swinging force during the lifting of the heavy object is removed to ensure that the heavy object quickly recovers stability after lifting. After the heavy object is lifted to a predetermined height, the driving wheel 26 controls the transmission assembly 2 to move inside the traveling frame 1. When the heavy object is swung by the wind in mid-air, the controller controls the electric push rod 254 to adjust the position of the mounting frame 251 to move the originally parallel lifting frame 251 to the predetermined height. The rope angle is enlarged to form an acute angle, which increases the anti-swing force of the suspension rope and keeps the heavy object stable in the air. When it is detected that the wind force exceeds the threshold, the controller can control the hydraulic cylinder 27 to work, and the hydraulic cylinder 27 lifts the transmission component 2 through the base 28. At this time, the upper end surface of the mounting seat 24 contacts the top of the traveling groove 12, and the base 28 engages with the engaging groove at the bottom of the traveling groove 12 through the engaging teeth, so that the transmission component 2 has sufficient locking force when the position inside the traveling frame 1 is fixed, further ensuring the stability of the transmission component 2 when it is locked, thereby preventing the movement of the transmission component 2 from causing the anti-swing component 3 to swing significantly.

[0058] In summary, the present invention provides an anti-swing boom of a crane, by setting a hook 33, wherein an upper fixed platform 321 is rotatably connected to a lower fixed platform 326 through a connecting column 322, the connecting column 322 is fixedly connected to a diffusion plate 323 on the outside, and a plurality of groups of mounting grooves 324 are symmetrically opened on the outside of the diffusion plate 323, and the two ends of steel wire ropes 325 equal to the number of mounting grooves 324 are fixedly connected to the adjacent sides of the upper fixed platform 321 and the lower fixed platform 326, and the steel wire ropes 325 pass through the inside of the mounting grooves 324 and are bent into an arc, so that when a heavy object is lifted, the plurality of groups of steel wire ropes 325 will be twisted through the hook 33 and the lower fixed platform 326, and the twisted steel wire ropes 325 will have a restoring force, so that the heavy object will tend to recover after swinging, and then the swinging force will be removed, further ensuring that the anti-swing component 3 quickly recovers stability after lifting, and reducing the swing amplitude and swing time of the heavy object.

[0059] Secondly, by arranging a hydraulic cylinder 27 and a base 28 under the transmission component 2, the base 28 is provided with a plurality of groups of meshing teeth, and a plurality of groups of meshing grooves adapted to the meshing are opened at the bottom of the traveling groove 12, so that after the hydraulic cylinder 27 lifts the transmission component 2 through the base 28, the base 28 meshes with the meshing grooves at the bottom of the traveling groove 12 through the meshing teeth, 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, thereby preventing the movement of the transmission component 2 from causing the anti-sway component 3 to swing greatly.

[0060] In addition, by setting up an adjustment mechanism 25, the mounting frame 251 and the fixing seat 255 are connected through an electric push rod 254, and two sets of rotating bearings 252 are arranged inside the mounting frame 251, wherein the lifting rope will pass through the two sets of rotating bearings 252, so that the controller controls the electric push rod 254 to adjust the position of the mounting frame 251, which will increase the originally parallel angle of the lifting rope to form an acute angle, thereby increasing the anti-swinging force of the lifting rope, keeping the weight stable in the air, and further reducing the swinging phenomenon of the weight.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
