Description

Technical Field

[0001] This utility model belongs to the field of mast technology, specifically relating to a mast mechanism with a convenient disassembly and assembly structure. Background Technology

[0002] In some construction sites, where suitable tower cranes or truck cranes are unavailable, mast mechanisms can be used as mast cranes or as external supports. For example, during building facade renovations, they can be used to support scaffolding or suspended platforms. When the building facade has a high construction height and traditional ground-mounted scaffolding is not suitable, mast mechanisms can serve as suspension points, suspending scaffolding or suspended platforms via steel cables to provide a safe working platform for construction workers.

[0003] The existing mast mechanism requires the base to be buried in the ground during use. When the location of the mast mechanism needs to be changed, it needs to be completely disassembled, the base dug out, and then reburied and reassembled at the new location. This is inconvenient for disassembly and relocation and is quite time-consuming. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing mast mechanisms require repeated installation and assembly when the location of the mast mechanism needs to be changed, which is quite time-consuming.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is a mast mechanism with a convenient disassembly and assembly structure, including a mast mechanism body and a convenient disassembly base. The bottom of the mast mechanism body is rotatably connected to a connecting base. The connecting base matches the internal shape of the convenient disassembly base, and the outer edge of the connecting base is provided with multiple positioning slots.

[0006] The disassembly base is a rectangular groove structure, and multiple buried plates protruding from the side of the disassembly base are provided on the lower outer side of the disassembly base. Positioning blocks are provided on the inner side of the disassembly base at multiple positioning slots. An adjusting nut is connected to one side of the positioning block through a first stud.

[0007] The four corners of the detachable base are provided with fitting grooves. An L-shaped positioning frame is connected in the fitting grooves by multiple second studs and fixing nuts, and the upper end face of the inner side of the positioning frame abuts against the upper end face of the connecting base.

[0008] As a preferred technical solution of this utility model, the connecting base is a stepped structure with a larger top and a smaller bottom. The internal shape of the connecting base matches that of the easy-to-disassemble base, and the upper surface of the connecting base is flush with the upper surface of the easy-to-disassemble base.

[0009] As a preferred technical solution of this utility model, the interior of the easy-to-disassemble base is provided with a plurality of guide grooves for storing positioning blocks. The first stud is fixedly connected to the positioning block, and the first stud passes through the easy-to-disassemble base and is connected to the external adjusting nut by thread engagement, so as to adjust the position of the positioning block by thread.

[0010] As a preferred embodiment of this utility model, a plurality of barrier plates perpendicular to the ground are provided between the plurality of buried plates.

[0011] As a preferred embodiment of this utility model, the lower part of the fitting groove does not penetrate the side of the easy-to-disassemble base, and the lower part of the positioning frame matches the shape of the fitting groove.

[0012] As a preferred embodiment of this utility model, a positioning plate is provided between the positioning frame and the multiple second studs and fixing nuts. The length of the positioning plate is greater than the width of the positioning frame, and the detachable base is provided with a corresponding slot at the positioning plate.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] This mast mechanism features a separate, easily detachable base, allowing the entire mast mechanism to be directly separated from the base for quick relocation. The base can be pre-embedded, and during replacement, it can be simply moved and secured. The overall process is convenient, quick, and the connection is stable and reliable.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Example 1:

[0025] As per the instruction manual Figure 1-4 As shown, a mast mechanism with a detachable structure includes a mast mechanism body 1 and a detachable base 2. A connecting base 3 is rotatably connected to the bottom of the mast mechanism body 1. The connecting base 3 matches the internal shape of the detachable base 2. The connecting base 3 has a stepped structure that is larger at the top and smaller at the bottom. The connecting base 3 matches the internal shape of the detachable base 2, and the upper end face of the connecting base 3 is flush with the upper end face of the detachable base 2. Multiple positioning slots 4 are provided on the outer edge of the connecting base 3.

[0026] In this utility model, the easy-to-disassemble base 2 is a rectangular groove structure. Multiple buried plates 5 protruding from the side of the easy-to-disassemble base 2 are provided on the lower outer side. Multiple barrier plates 14 perpendicular to the ground are provided between the multiple buried plates 5. Positioning blocks 6 are provided on the inner side of the easy-to-disassemble base 2 at multiple positioning slots 4. One side of the positioning block 6 is connected to an adjusting nut 8 through a first stud 7. Multiple guide grooves 13 for receiving positioning blocks 6 are provided inside the easy-to-disassemble base 2. The first stud 7 is fixedly connected to the positioning block 6, and the first stud 7 passes through the easy-to-disassemble base 2 and is connected to the external adjusting nut 8 through thread engagement, so as to adjust the position of the positioning block 6 through the thread.

[0027] As per the instruction manual Figure 5 As shown, there are fitting grooves 9 at the four upper corners of the easy-to-disassemble base 2. The lower part of the fitting grooves 9 does not penetrate the side of the easy-to-disassemble base 2. An L-shaped positioning frame 12 is connected to the fitting groove 9 by multiple second studs 10 and fixing nuts 11. The upper end face of the inner side of the positioning frame 12 abuts against the upper end face of the connecting base 3. The lower part of the positioning frame 12 matches the shape of the fitting groove 9. A positioning plate 15 is provided between the positioning frame 12 and the multiple second studs 10 and fixing nuts 11. The length of the positioning plate 15 is greater than the width of the positioning frame 12. The easy-to-disassemble base 2 is provided with a corresponding slot 16 at the positioning plate 15.

[0028] In the specific implementation of this utility model, the easy-to-disassemble base 2 is first placed in a suitable installation position. The multiple buried plates 5 on its outer lower side can be partially buried in the ground or other installation planes, which plays a role in initially fixing and stabilizing the base. Furthermore, the barrier plate 14 between the multiple buried plates 5 can enhance the stability of the connection with the installation plane (such as the ground) and prevent unnecessary shaking of the base during subsequent use. The easy-to-disassemble base 2 is provided with a guide groove 13 for storing the positioning block 6. Through the cooperation of the first stud 7 and the adjusting nut 8, the position of the positioning block 6 in the guide groove 13 can be adjusted so that it can accurately correspond to the positioning slot 4 on the subsequent connection base 3, thus preparing for the installation of the connection base 3.

[0029] Connect the connecting base 3 to the easy-to-disassemble base 2. Since the connecting base 3 has a stepped structure that is larger at the top and smaller at the bottom and matches the internal shape of the easy-to-disassemble base 2, it can be embedded into the easy-to-disassemble base 2 with relatively high precision. At the same time, the multiple positioning slots 4 on the outer edge of the connecting base 3 should be aligned with the corresponding positioning blocks 6 on the inner side of the easy-to-disassemble base 2. After the connection is completed, rotate the adjusting nut 8 to insert the positioning block 6 into the positioning slot 4 to achieve the horizontal positioning of the connecting base 3, ensuring that its installation position is accurate and stable and that it will not easily shift.

[0030] After positioning the connecting base 3 using the positioning block 6, the L-shaped positioning frame 12 is placed into the fitting groove 9. Multiple second studs 10 pass through the positioning frame 12 and positioning plate 15, engaging with the fixing nut 11 to fix the positioning frame 12 onto the detachable base 2. The upper inner surface of the positioning frame 12 abuts against the upper surface of the connecting base 3, thus limiting the vertical movement of the connecting base 3 and preventing it from detaching upwards. Reversing the installation steps allows the connecting base 3 to be removed from the detachable base 2, completing the separation of the mast mechanism body 1 from the detachable base 2. This facilitates easy disassembly and assembly, making subsequent maintenance and relocation of the mast mechanism easier.

[0031] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
