[0002] A crane is a multi-action lifting machine that can lift heavy objects vertically and carry them horizontally within a certain range. It is also called an overhead crane, overhead crane, or crane. There are many types of cranes, such as gantry cranes, bridge cranes, etc.

[0003] At present, most gantry cranes use wire ropes for lifting. When the electric hoist moves horizontally, the hook and the material will perform a pendulum motion under the action of inertia. The material needs a while to stabilize, resulting in low lifting efficiency.

[0004] So we proposed an anti-sway crane to solve the above problems. Utility Model Content

[0010] A column is arranged on the top of the bottom beam, a first guide groove is vertically opened on the column, a cross plate is slidably installed in the first guide groove, a second guide groove is horizontally opened on the cross plate, and the connecting column is slidably installed in the second guide groove.

[0011] Furthermore, connecting plates slidably connected to the first guide groove are fixed at both ends of the transverse plate, and an extension plate is provided at one end of the connecting plate away from the transverse plate, and the width of the extension plate is greater than the width of the first guide groove.

[0012] Furthermore, a first roller is rotatably mounted on the side wall of the extension plate, and the first roller is rollingly connected to the side wall of the column.

[0013] Furthermore, sliding grooves slidably connected to the inner wall of the second guide groove are provided on both sides of the connecting column, and the inner wall of the second guide groove is in contact with the bottom wall of the sliding groove.

[0014] Preferably, a second roller is rotatably mounted on the bottom wall of the slide groove, and the second roller is rollingly connected to the bottom wall of the second guide groove.

[0015] Preferably, walking wheels are provided at the bottom of the bottom beam.

[0016] Three beneficial effects

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] By setting a column between the top beam and the cross beam, the first guide groove on the column can limit the hook horizontally through the cross plate to prevent shaking during the lifting of the goods. By setting a second guide groove on the cross plate, it can limit the goods during the lateral movement of the goods to prevent the hook from swinging laterally or rotating, making the lifting more stable, saving the time required for the goods to swing to a stable state, and improving the lifting efficiency.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. It should be noted that the words "front", "back", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4 As shown, the utility model provides an anti-sway crane, including a top beam 3 and two symmetrically arranged bottom beams 1, two support frames 2 are arranged on the top of the bottom beam 1, and the two support frames 2 and the bottom beam 1 form a triangular structure to enhance stability, the two ends of the top beam 3 are fixed to the two bottom beams 1 through the support frames 2, and an electric hoist 5 is arranged at the bottom of the top beam 3 through a transverse movement mechanism 4, and a connecting column 6 is arranged at the output end of the electric hoist 5, and a hook 7 is arranged at the bottom of the connecting column 6.

[0026] A column 8 is vertically fixed on the top of the two bottom beams 1, and a first guide groove 9 is vertically opened on the column 8. The same cross plate 10 is arranged between the two first guide grooves 9. Connecting plates 12 slidably connected to the first guide groove 9 are fixed at both ends of the cross plate 10. A second guide groove 11 is horizontally opened on the cross plate 10. Slide grooves 14 slidably connected to the inner wall of the second guide groove 11 are opened on both sides of the connecting column 6, and the inner wall of the second guide groove 11 is in contact with the bottom wall of the slide groove 14.

[0027] When lifting the goods, the first guide groove 9 on the column 8 plays a horizontal limiting role on the hook 7 through the cross plate 10 to prevent the goods from swinging or rotating during the lifting process. The second guide groove 11 on the cross plate 10, together with the slide groove 14 opened on the connecting column 6, can limit the goods during the lateral movement process to prevent the hook 7 from swinging horizontally or rotating, making the lifting more stable, saving the time required for the goods to swing to a stable state, and improving the lifting and subsequent placement and transportation efficiency.

[0028] As a preferred technical solution of the utility model: the top beam 3 adopts an I-beam, the transverse movement mechanism 4 and the crossbeam vehicle are adopted, specifically, rolling wheels connected to the I-beam are arranged on both sides of the concave plate, and the rolling wheels can be driven by a motor to ensure that the concave plate can be transversely moved on the top beam 3.

[0029] As a preferred technical solution of the utility model: an extension plate 13 is provided at one end of the connecting plate 12 away from the horizontal plate 10, and the width of the extension plate 13 is greater than the width of the first guide groove 9. The setting of the extension plate 13 can prevent the horizontal plate 10 from tilting during the lifting process, making it more stable.

[0030] As a preferred technical solution of the utility model: a first roller 15 is rotatably installed on the side wall of the extension plate 13, and the first roller 15 is rollingly connected to the side wall of the column 8; a second roller 16 is rotatably installed on the bottom wall of the slide groove 14, and the second roller 16 is rollingly connected to the bottom wall of the slide groove 14. The setting of the first roller 15 and the second roller 16 can convert the sliding friction between the extension plate 13 and the column 8 and between the slide groove 14 and the second guide groove 11 into rolling friction, thereby reducing the movement resistance and making it move more smoothly.
