Description

Technical Field

[0001] The utility model relates to the technical field of lifting and transportation, in particular to a device for preventing a grab bucket wire rope from falling out of a groove. Background Art

[0002] Grab cranes are highly efficient and flexible material handling equipment, widely used in various industries, including ports, docks, steel, electricity, and building materials. Combining the lifting capacity of an overhead crane with the gripping function of a grab bucket, they enable rapid and accurate grabbing and handling of a wide range of bulk materials. Grab cranes are distinguished by ease of operation, high efficiency, and adaptability. Their operating principle is to raise the grab bucket to a specified height via the crane's wire rope and pulley system. The grab bucket is then opened or closed by operating a control mechanism to grab or release the material. Furthermore, the crane's travel and lifting mechanisms ensure flexible three-dimensional movement of the grab bucket, meeting a variety of complex handling needs.

[0003] When grabbing materials with existing grab cranes, the wire rope may fall out of the pulley groove due to the tilted state of the materials, which will affect the grab bucket, thereby reducing work efficiency and increasing maintenance costs. Utility Model Content

To achieve the above purpose, the present utility model provides the following technical solution: a device to prevent the wire rope of a grab bucket from falling out of the groove, comprising a main frame, a bearing is provided at the bottom of the main frame, a wire rope guide channel is opened inside the main frame, a wire rope body is movably connected to the inside of the wire rope guide channel, a wire rope body guide channel is provided in the middle of the main frame, which plays a role in limiting the displacement of the wire rope body, the main frame and the grab bucket body are connected by a bearing, which ensures that the relative position of the main frame remains unchanged, and when grabbing materials, regardless of whether the materials are flat or not, the wire rope body is forced to be restricted in a normal position, thereby preventing the wire rope body from falling off the pulley groove, improving its working efficiency and reducing its maintenance cost.

[0005] Further preferably, the bottom of the bearing is rotatably connected to a grab body, one side of the grab body is fixedly connected to a bracket, the bracket is rotatably connected to the main frame, and one side of the wire rope body is rotatably connected to a pulley.

[0006] Further preferably, the main frame is arranged above the grab body and connected to the main frame through a bearing, and the wire guide rope channel is in the same direction as and coincides with the wire rope body when the overhead crane grab body is in a vertical state.

[0007] Further preferably, the length of the main frame is 1.2 to 1.5 times the maximum distance of the wire rope body, and the thickness of the main frame is 1.1 to 1.3 times the diameter of the wire rope body.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] In the utility model, a wire rope guide channel is provided in the middle of the main frame, which plays a role in limiting the displacement of the wire rope body. The main frame and the grab bucket body are connected by bearings, which ensures that the relative position of the main frame remains unchanged.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0017] See also Figure 1-Figure 5The utility model provides a technical solution: a device for preventing the grab wire rope from falling out of the groove, comprising a main frame 1, a bearing 2 is provided at the bottom of the main frame 1, a wire guide rope channel 3 is opened inside the main frame 1, and the wire guide rope channel 3 is movably connected to the wire rope body 4. The main frame 1 serves as the main structure of the entire device, and provides a clear guide path for the wire rope body 4 through the wire guide rope channel 3 inside it. The length and thickness of the main frame 1 are designed to be slightly larger than the maximum running distance and diameter of the wire rope body 4 to ensure sufficient support and inclusiveness, reduce the friction between the wire rope body 4 and the inner wall of the wire guide rope channel 3, and prevent the wire rope body 4 from falling out of the channel. The bearing 2 is installed at the bottom of the main frame 1, so that the grab body 5 can rotate freely relative to the main frame 1, keeping the wire rope body 4 always in the best guiding state. At the same time, the rotation of the bearing 2 also reduces the wear and resistance caused by friction.

[0018] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the bottom of the bearing 2 is rotatably connected to the grab body 5, one side of the grab body 5 is fixedly connected to the bracket 6, the bracket 6 is rotatably connected to the main frame 1, and one side of the wire rope body 4 is rotatably connected to the pulley 7. When the crane starts working, the wire rope body 4 starts to move under the action of the driving force. Due to the fixing and guiding function of the main frame 1 and the assistance of the pulley 7, the wire rope body 4 can move stably along the predetermined wire guide rope channel 3. Even if the grab body 5 tilts or rotates during operation, the main frame 1 can adapt to such changes through the rotation of the bearing 2 to ensure that the wire rope body 4 always remains in the channel.

[0019] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the main frame 1 is arranged above the grab body 5 and is connected to the main frame 1 through the bearing 2. The wire guide rope channel 3 is in the same direction as and coincides with the wire rope body 4 when the overhead crane grab body 5 is in a vertical state.

[0020] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the length of the main frame 1 is 2 to 1.5 times the maximum distance of the wire rope body 4, and the thickness of the main frame 1 is 1.1 to 1.3 times the diameter of the wire rope body 4.

[0021] The use method and advantages of the utility model: The device for preventing the grab bucket wire rope from falling out of the groove, when in use, works as follows:

[0022] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the main frame 1 serves as the main structure of the entire device. It provides a clear guide path for the wire rope body 4 through the wire rope guide channel 3 inside it. The length and thickness of the main frame 1 are designed to be slightly larger than the maximum running distance and diameter of the wire rope body 4 to ensure sufficient support and containment, reduce friction between the wire rope body 4 and the inner wall of the wire rope guide channel 3, and prevent the wire rope body 4 from escaping the channel. The bearing 2 is installed at the bottom of the main frame 1, allowing the grab body 5 to rotate freely relative to the main frame 1, keeping the wire rope body 4 in the optimal guiding state at all times. At the same time, the rotation of the bearing 2 also reduces wear and resistance caused by friction. When the crane starts working, the wire rope body 4 begins to move under the action of the driving force. Due to the fixing and guiding function of the main frame 1 and the assistance of the pulley 7, the wire rope body 4 can move stably along the predetermined wire rope guide channel 3. Even if the grab body 5 tilts or rotates during operation, the main frame 1 can adapt to such changes through the rotation of the bearing 2, ensuring that the wire rope body 4 always remains in the channel.
