Description

Technical Field

[0001] The utility model relates to the field of cranes, in particular to an anti-sway crane. Background Art

[0002] A crane is a device used to lift and move heavy objects on engineering and construction sites. It is usually composed of a bracket, an arm, a winch and a hook. Cranes can be divided into various types such as cranes, tower cranes, bridge cranes, etc. according to different needs and occasions. In engineering construction, cranes play an important role in lifting and moving heavy objects, improving work efficiency and safety.

[0003] When a crane lifts goods, the goods may sway due to inertia or wind. In order to prevent the goods from swaying, an anti-sway crane is needed for lifting. For example, the prior art Chinese patent announcement number "CN213505647U" discloses an anti-sway crane, including a support column, a control box is fixedly connected to the right bottom outer wall of the support column, and the tops of both ends of the support column are fixedly connected to longitudinal axis grooves. A transverse movable support bar is fixedly connected horizontally between the two ends of the longitudinal axis groove through the support of the support column, and the top of the transverse movable support bar slides and buckles A transverse axis moving block is connected, a top box and a first motor are fixedly connected to the top of the transverse axis moving block, a first reel and a second reel are fixedly connected inside the top box, the first reel is fixedly connected to a first lifting rope through the inside of the top box, and the second reel is fixedly connected to a second lifting rope through the inside of the top box. This relates to the technical field of lifting equipment. The anti-sway crane uses a double-reel double lifting rope design to improve the load-bearing capacity. The double lifting ropes can be lifted separately, which improves the convenience of lifting two objects at the same time. Two force points and one traction reduce the swing of the crane when moving objects.

[0004] Some cranes prevent swaying by installing two hooks on the cargo that are fixed by lifting ropes. However, in actual operation, such cranes do not have the ability to move cargo horizontally and need to be pulled by a tractor to transport the cargo. In addition, considering that the cargo will sway due to the inertia of the cargo and the influence of wind during movement, the excessively long lifting rope will not be able to play a good anti-swaying role due to the lack of support between the pair of hooks. Utility Model Content

[0005] The utility model aims to solve the above-mentioned shortcomings of the prior art, that is, the goods cannot be moved and transported and the anti-sway effect is poor, and proposes an anti-sway crane.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A sway-proof crane comprises a frame 1, the top of the frame 1 is slidably connected to a sliding frame 3 through a guide groove 2, the sliding frame 3 is provided with a plurality of winding wheels 5 connected to steel cables 4, a support frame 6 is fixedly installed on the top of the frame 1, the support frame 6 is provided with a guide wheel 7, the other end of the steel cable 4 is fixed with cargo 42 through a hook 41, the bottom of the sliding frame 3 is located on both sides of the straight groove 84 and is rotatably connected to rollers, and the friction between the sliding frame 3 and the guide groove 2 can be reduced by using the rollers.

[0022] A driving assembly 8 for driving the sliding frame 3 to move is disposed on the side of the frame 1 , and an anti-sway assembly 9 for preventing the goods 42 from shaking is disposed on the top thereof.

[0023] Furthermore, the driving assembly 8 includes a first motor 81 fixedly installed on the side of the frame 1, a screw rod 82 is rotatably connected in the guide groove 2 and a round rod 83 is fixedly installed, one end of the screw rod 82 passes through the frame 1 and is fixedly connected to the shaft end of the first motor 81, and the first motor 81 drives the screw rod 82 to cooperate with the round rod 83 to drive the sliding frame 3 to move, and then transport the cargo 42.

[0024] Furthermore, the bottom of the sliding frame 3 is threadedly connected to the screw rod 82 and slidably connected to the round rod 83. The sliding frame 3, the guide groove 2 and the bottom of the support frame 6 are all penetrated by a straight groove 84. The steel cable 4 is slidably connected in the straight groove 84. The straight groove 84 is used to provide space for the movement of the steel cable 4, and the straight groove 84 is opened between the screw rod 82 and the round rod 83 without affecting the movement of the sliding frame 3.

[0025] In more detail, the anti-sway assembly 9 includes a fixed frame 91 fixedly installed in the sliding frame 3, and a plurality of the winding wheels 5 are rotatably connected in the fixed frame 91. A second motor 92 is fixedly installed on the top of the sliding frame 3. The shaft end of the second motor 92 passes through the fixed frame 91 and is fixedly connected to one end of one of the winding wheels 5. A gear 93 is fixedly installed at one end of the winding wheel 5, and the gears 93 are meshed and rotated.

[0026] It is worth mentioning that there are three winding wheels 5, which are arranged in a triangular structure. The second motor 92 drives the topmost winding wheel 5 to rotate, and the gears 93 are engaged with each other to make the winding wheels 5 rotate synchronously, thereby driving the three steel cables 4 to rise and fall synchronously, thereby stabilizing the cargo 42 to the greatest extent. The three steel cables 4 are respectively fixed to the top and both sides of the cargo 42 by the hooks 41. The steel cables 4 can maintain the tension through the guide wheels 7 to minimize the shaking caused by the inertia and wind force of the cargo 42. It should be noted that, considering that the length of the steel cables 4 on both sides is greater than that of the middle steel cable 4 under the action of the guide wheels 7, the height of the hook 41 of the middle steel cable 4 needs to be adjusted during lifting.

[0027] In general, a curved rod 94 is slidably connected inside the support frame 6, and extension rods 95 are slidably connected inside the two ends of the curved rod 94, and slots 96 are penetrated by the ends of the curved rod 94 and the extension rod 95, and bolts 97 are inserted into the slots 96.

The curved rod 94 is provided with a recessed portion, which can avoid the situation where the steel cable 4 is stuck. The length of the extension rod 95 is adjusted by the bolts 97, and then the overall length of the curved rod 94 is changed, so that the steel cables 4 on both sides can adapt to the cargo 42 of different lengths.

[0028] Finally, the other end of the extension rod 95 is rotatably connected to the guide wheel 7, and the guide wheel 7 is rotatably connected to the straight groove 84, and it can rotate in contact with the steel cable 4, and the curved rod 94 cooperates with the guide wheel 7 to provide support for the steel cables 4 on both sides to maintain tension to stabilize the cargo 42, and when the sliding frame 3 moves, the steel cable 4 can be used to push the curved rod 94 to move.

[0029] Working method: When working, the extension rod 95 is fixed by bolts 97 so that the length of the curved rod 94 can adapt to the length of the cargo 42, ensuring that the guide wheel 7 can provide support for the steel cable 4, and then the hooks 41 of the three steel cables 4 are fixed on the cargo 42, and the second motor 92 drives the winding wheel 5 to rotate. Under the action of multiple gears 93, the three winding wheels 5 rotate at the same time and drive the steel cables 4 to lift the cargo 42. Then the first motor 81 drives the screw rod 82 to cooperate with the round rod 83 to drive the cargo 42 to move.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
