[0001] This utility model relates to the field of hoisting and transportation equipment technology, and in particular to a rotary crane. Background Technology

[0002] A slewing crane is a type of engineering machinery that achieves horizontal rotation through a slewing mechanism. It is widely used in ports, construction, mining, nuclear power, and other fields. When the main beam of a slewing crane rotates, the electric hoist also rotates along with it. To ensure safety, the equipment is usually equipped with an anchoring device to ensure that the electric hoist is firmly fixed when not in operation, preventing the hoist from moving when the main beam rotates.

[0003] In existing technologies, electric hoist anchoring devices are fixed blocks welded onto the main beam of the crane. When the main beam needs to rotate, the electric hoist must be moved to a designated position for anchoring, which is inconvenient and has low work efficiency. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the defect that the electric hoist of the rotary crane in the prior art cannot be flexibly anchored, resulting in low work efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides a rotary crane, comprising: A support assembly, comprising a crossbeam rail and a movable frame, wherein the movable frame is suspended on both sides of the crossbeam rail and is rotatably connected to the crossbeam rail, and an electric hoist is mounted on the movable frame; A pair of anchoring components are symmetrically arranged on both sides of the crossbeam track. Each anchoring component includes a fixed frame, an electric push rod, and a push plate. The fixed frame is connected to the movable frame. The fixed end of the electric push rod is connected to the fixed frame, and the telescopic end of the electric push rod is connected to the push plate. The electric push rod drives the push plate to abut against the crossbeam track.

[0006] In one embodiment of this utility model, a rubber pad is provided on the surface of the push plate away from the electric push rod, and the surface of the rubber pad is provided with anti-slip texture.

[0007] In one embodiment of this utility model, the rubber pad and the push plate are detachably connected.

[0008] In one embodiment of this utility model, a fixing plate is provided on the side of the push plate near the electric push rod. The fixing plate is arranged parallel to the push plate and is connected to the fixing frame.

[0009] In one embodiment of this utility model, a connecting rod is provided between the electric push rod and the push plate, and the connecting rod passes through the fixed plate and connects to the push plate.

[0010] In one embodiment of this utility model, a pair of guide rods are provided between the fixed plate and the push plate, and the pair of guide rods are symmetrically arranged on both sides of the connecting rod; one end of the guide rod is connected to the push plate, and the other end of the guide rod passes through the fixed plate.

[0011] In one embodiment of this utility model, an elastic element is provided between the fixing plate and the push plate, and the elastic element is sleeved on the outside of the guide rod.

[0012] In one embodiment of this utility model, a limit nut is provided at the end of the guide rod away from the push plate.

[0013] In one embodiment of this utility model, the connecting rod and the electric push rod are detachably connected.

[0014] In one embodiment of this utility model, rollers are provided between the movable frame and the crossbeam track.

[0015] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art: This utility model discloses a rotary crane, in which at least one pair of anchoring components are symmetrically arranged on both sides of the moving frame.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0018] Reference Figures 1-4 As shown, this utility model discloses a rotary crane, comprising: Support assembly 1, which includes a crossbeam rail 11 and a movable frame 12. The movable frame 12 is suspended on both sides of the crossbeam rail 11 and is rotatably connected to the crossbeam rail 11. An electric hoist 13 is provided on the movable frame 12. A pair of anchoring components 2 are symmetrically arranged on both sides of the crossbeam track 11. Each anchoring component 2 includes a fixed frame 21, an electric push rod 22, and a push plate 23. The fixed frame 21 is connected to the movable frame 12. The fixed end of the electric push rod 22 is connected to the fixed frame 21, and the telescopic end of the electric push rod 22 is connected to the push plate 23. The electric push rod 22 drives the push plate 23 to abut against the crossbeam track 11.

[0019] In this invention, the movable frame 12 is rolledly connected to the crossbeam rail 11, and the movable frame 12 is suspended on the crossbeam rail 11. An electric hoist 13 is mounted on the movable frame 12, and the movable frame 12 moves axially along the crossbeam rail 11, causing the electric hoist 13 to move synchronously. The fixed frame 21 in the anchoring assembly 2 is fixedly connected to the movable frame 12, and an electric push rod 22 is mounted on the fixed frame 21. The electric push rod 22 extends, causing the push plate 23 to move and contact the crossbeam rail 11. In this invention, at least one pair of anchoring assemblies 2 are symmetrically arranged on both sides of the movable frame 12. The anchoring assemblies 2 on both sides move synchronously, causing the push plates 23 on both sides to simultaneously abut against the crossbeam rail 11. Utilizing the friction between the push plate 23 and the crossbeam rail 11, the movable frame 12 and the electric hoist 13 are fixed, allowing the electric hoist 13 to stop at any position and perform a clamping action in a non-working state without needing to move to a designated position for anchoring, saving adjustment time and improving the overall working efficiency of the machine.

[0020] As a preferred embodiment of this utility model, the movable frame 12 is equipped with a control box 122, and a remote control module is installed inside the control box 122. The control signal of the electric push rod 22 is connected to the control box 122, which can realize the remote control of the electric push rod 22.

[0021] Furthermore, a rubber pad 24 is provided on the surface of the push plate 23 away from the electric push rod 22, and the surface of the rubber pad 24 is provided with anti-slip texture.

[0022] Specifically, a rubber pad 24 is provided on the surface of the push plate 23. During actual operation, the side of the push plate 23 with the rubber pad 24 contacts the crossbeam rail 11. Utilizing the plasticity of the rubber pad 24, the push plate can press the rubber pad 24 firmly onto the surface of the crossbeam rail 11. This increases the friction between the push plate 23 and the crossbeam rail 11, further ensuring the stability of the electric hoist 13, and also extending the service life of the push plate 23.

[0023] Furthermore, the rubber pad 24 is detachably connected to the push plate 23.

[0024] Specifically, in actual operation, prolonged use will cause wear on the rubber pad 24. In this utility model, the rubber pad 24 and the push plate 23 are fixed by bolts, which facilitates the installation and disassembly of the rubber pad 24. Regularly replacing the rubber pad 24 can ensure the stability and reliability of the anchoring point.

[0025] Furthermore, a fixing plate 25 is provided on the side of the push plate 23 near the electric push rod 22. The fixing plate 25 is arranged parallel to the push plate 23 and is connected to the fixing frame 21. A connecting rod 26 is provided between the electric push rod 22 and the push plate 23, and the connecting rod 26 passes through the fixing plate 25 and connects to the push plate 23.

[0026] Specifically, during the actual assembly process, depending on the actual installation position of the movable frame 12, electric push rods 22 of different lengths can be selected. Alternatively, a connecting rod 26 can be installed at the telescopic end of the electric push rod 22 to extend the length of the telescopic rod, allowing the push plate 23 to contact the crossbeam guide rail within the effective stroke of the electric push rod 22. As a preferred embodiment of this utility model, the connecting rod 26 and the electric push rod 22 are detachably connected by bolts.

[0027] Furthermore, a pair of guide rods 27 are provided between the fixing plate 25 and the push plate 23, and the pair of guide rods 27 are symmetrically arranged on both sides of the connecting rod 26; one end of the guide rod 27 is connected to the push plate 23, and the other end of the guide rod 27 passes through the fixing plate 25. An elastic element 28 is provided between the fixing plate 25 and the push plate 23, and the elastic element 28 is sleeved on the outside of the guide rod 27.

[0028] Specifically, during the actual assembly process, the connecting rod 26 is installed at the center of the entire push plate 23. A pair of guide rods 27 are symmetrically arranged on both sides of the connecting rod 26. An elastic element 28 is sleeved on the outer side of the guide rod 27. When the electric push rod 22 is in the retracted state, the elastic element 28 is pressed and retracted between the fixed plate 25 and the push plate 23. When the electric push rod 22 extends and drives the push plate 23 to abut against the crossbeam rail 11, the preload of the elastic element 28 is used to generate pressure on both sides of the edge of the push plate 23, so that the edge of the push plate 23 can also be pressed against the surface of the crossbeam rail 11, further increasing the contact area between the push plate 23 and the crossbeam rail 11, and ensuring the stability of the position of the electric hoist 13.

[0029] Furthermore, a limit nut 29 is provided at the end of the guide rod 27 away from the push plate 23.

[0030] Specifically, one end of the guide rod 27 is fixedly connected to the push rod, and the other end of the guide rod 27 passes through the fixed plate 25, with the stroke of the guide rod 27 limited by the limiting nut 29.

[0031] Furthermore, a roller 121 is provided between the movable frame 12 and the crossbeam track 11.

[0032] Specifically, during use, the position of the electric hoist 13 on the crossbeam track 11 can be adjusted by driving the roller 121 to rotate.

[0033] In summary, this utility model introduces a rotary crane. In this utility model, at least one pair of anchoring components 2 are symmetrically arranged on both sides of the moving frame 12. Before the main rotating beam rotates, the electric push rod 22 is controlled to move, causing the push plates 23 on both sides to abut against the crossbeam track 11, thereby fixing the position of the electric hoist 13. This utility model enables the electric hoist 13 to stop at any position and perform clamping action in the non-working state without needing to move to a designated anchoring position, saving adjustment time and improving the overall working efficiency of the machine.
