Description

Technical Field

[0001] The utility model relates to a cantilever crane angle adjustment mechanism, in particular to a cantilever crane angle adjustment mechanism with a rotation limiting function, belonging to the technical field of cantilever cranes. Background Art

[0002] A cantilever crane is a common lifting equipment. It has a rotatable cantilever. One end of the cantilever is fixed to a column or a wall, and the other end is equipped with a hook or other lifting device. The cantilever can rotate and rise and fall freely within a certain angle and range, so as to realize the lifting and handling of heavy objects. Cantilever cranes have the advantages of compact structure, small space occupation, flexible operation and high work efficiency. They are usually suitable for workshops, warehouses, docks and other places. They can be used for lifting light goods, equipment maintenance, material loading and unloading and other operations.

[0003] Traditional cantilever cranes have a limited operating range and cannot flexibly cover a larger work area. For cargo lifting tasks in different positions and directions, they cannot flexibly adjust the angle to directly lift the cargo, which may require additional handling operations and makes it difficult to adapt to complex and changing working environments and lifting requirements, thereby increasing work processes and time costs.

[0004] Usually manual operation is required to adjust the angle, which increases the workload of the operator and is easily affected by human factors and causes errors. It is difficult to achieve precise angle control and may not be able to meet certain operational requirements that require extremely high lifting angles.

[0005] Therefore, it is urgent to improve the cantilever angle adjustment mechanism with a rotation limiting function to solve the above-mentioned problems. Utility Model Content

[0006] The utility model aims to provide a cantilever crane angle adjustment mechanism with a rotation limit function, wherein two limit ear plates are fixed on the cantilever column, and the limit plate is connected to the cantilever through the mounting holes on the limit plate. When the cantilever rotates, the limit plate is driven to rotate. When the limit plate stops rotating, the first socket on the limit plate coincides with the second sockets on the two limit ear plates. At this time, the positioning pin is inserted into the first socket and the second socket to limit and fix the limit plate and the limit ear plates. Therefore, the cantilever crane can be rotated at different angles to lift goods, adapt to complex and changeable working environments and lifting needs, thereby shortening the work process and time cost.

[0007] In order to achieve the above-mentioned purpose, the main technical solutions adopted by the utility model include:

[0008] A cantilever hanging angle adjustment mechanism with a rotation limiting function comprises a limiting plate, on which a plurality of evenly distributed first sockets are provided, and two limiting ear plates are arranged on one side of the limiting plate, on which two second sockets are provided, and the second sockets correspond to the first sockets.

[0009] Preferably, a mounting hole is provided at the center of the limiting plate.

[0010] Preferably, a connecting block is fixedly mounted on one end of the limiting ear plate away from the limiting plate.

[0011] Preferably, a fixing rod is fixedly mounted on the connecting block.

[0012] Preferably, a groove is provided on the fixing rod.

[0013] Preferably, through holes are provided on the connecting block and the fixing rod.

[0014] The utility model has at least the following beneficial effects:

[0015] 1. The utility model fixes two limit ear plates on the cantilever column, connects the limit plate with the cantilever through the mounting hole on the limit plate, and drives the limit plate to rotate when the cantilever rotates. When the limit plate stops rotating, the first plug hole on the limit plate coincides with the second plug holes on the two limit ear plates. At this time, the positioning pin is inserted into the first plug hole and the second plug hole to limit and fix the limit plate and the limit ear plates. Then, the cantilever crane can rotate at different angles to lift goods, adapt to complex and changeable working environment and lifting needs, thereby shortening the work process and time cost.

[0022] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] like Figure 1-Figure 4 As shown, the cantilever crane angle adjustment mechanism with a rotation limit function provided in this embodiment includes a limit plate 1, a plurality of evenly distributed first holes 2 are provided on the limit plate 1, and two limit ear plates 3 are provided on one side of the limit plate 1, and two second holes 4 are provided on the limit ear plates 3, and the second holes 4 correspond to the first holes 2. The two limit ear plates 3 are fixed on the cantilever column, and the limit plate 1 is connected to the cantilever through the mounting holes 2 on the limit plate 1. When the cantilever rotates, the limit plate 1 is driven to rotate. When the limit plate 1 stops rotating, the first hole 2 on the limit plate 1 coincides with the second holes 4 on the two limit ear plates 3. At this time, the locating pin is inserted into the first hole 2 and the second hole 4 to limit and fix the limit plate 1 and the limit ear plates 3. Then, the cantilever crane can be rotated at different angles to lift goods, adapt to complex and changeable working environments and lifting requirements, thereby shortening the work process and time cost.

[0024] Further, such as Figure 1 As shown, a mounting hole 5 is opened at the center of the limit plate 1, and the mounting hole 5 can make the connection between the limit plate 1 and the cantilever more firmly, thereby reducing looseness or displacement caused by vibration or external force during the operation of the cantilever crane.

[0025] Further, such as Figure 1 As shown, a connecting block 6 is fixedly installed at one end of the limiting ear plate 3 away from the limiting plate 1, a fixing rod 7 is fixedly installed on the connecting block 6, a groove 8 is provided on the fixing rod 7, and through holes 9 are provided on both the connecting block 6 and the fixing rod 7. A mounting piece passes through the through hole 9, and the mounting piece abuts against the groove 8 to fix the limiting ear plate 3, the connecting block 6 and the fixing rod 7 on the cantilever column to prevent the limiting ear plate 3 from shaking or falling off during operation.

[0026] like Figure 1-Figure 4 As shown, the principle of the cantilever suspension angle adjustment mechanism with rotation limit function provided in this embodiment is as follows:

[0027] The mounting piece passes through the through hole 9, and the mounting piece abuts against the groove 8, fixing the limit ear plate 3, the connecting block 6 and the fixing rod 7 on the cantilever column, and connecting the limit plate 1 with the cantilever through the mounting hole 2 on the limit plate 1. When the cantilever rotates, the limit plate 1 is driven to rotate. When the limit plate 1 stops rotating, the first socket 2 on the limit plate 1 coincides with the second socket 4 on the two limit ear plates 3. At this time, the locating pin is inserted into the first socket 2 and the second socket 4 to limit and fix the limit plate 1 and the limit ear plate 3. Then, the cantilever crane can be rotated at different angles to lift goods, adapt to complex and changeable working environment and lifting requirements, thereby shortening the work process and time cost.

[0028] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0029] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0030] The above description shows and describes several preferred embodiments of the utility model, but as mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept described herein through the above teachings or the technology or knowledge of the relevant field.
