Description

Technical Field

[0001] The utility model belongs to the technical field of the installation of cantilever scaffolds, and particularly relates to a tool for installing and disassembling the flower basket tie rods of a cantilever scaffold. Background Art

[0002] The flower basket of the cantilever scaffold, that is, the cantilevered scaffold, is generally installed on the outside of the staircase during building construction. It is a scaffold that is installed by drilling holes on the side of the building and installing expansion bolts for diagonal bracing. Since the flower basket of the cantilever scaffold is installed on the outside of the structure, it is difficult for manual installation and operation, and there are potential safety hazards. Therefore, during the installation of the flower basket of the cantilever scaffold, a special installation tool that can extend outside the staircase or building is required to install the flower basket of the cantilever scaffold, so as to reduce the burden on construction workers and ensure the installation effect of the flower basket of the cantilever scaffold.

[0003] For example, a tool for installing and disassembling the flower basket tie rods of a cantilever scaffold is disclosed in the Chinese utility model patent with the publication number CN 217205367 U. The installation and disassembly tool includes a handle, and the front end of the handle has an end head. An arc opening is provided on one side of the end head, and a limit card slot is opened on the inner wall of the arc opening. When in use, by adopting a special opening wrench for processing, the installation and disassembly efficiency of the flower basket tie rods of the cantilever scaffold is greatly improved, and the problem that the traditional installation and disassembly method easily causes the deformation and damage of the tie rods is solved. However, during the installation of the outdoor flower basket of the cantilever scaffold, since an effective working surface has not been formed outdoors in the initial stage of the scaffold installation, the following problems still exist when installing the flower basket tie rods of the cantilever scaffold described in the above solution;

[0004] 1. The length of the installation and disassembly tool is short and cannot be adjusted. The staff cannot stand on the operation plane of the outdoor scaffold to install the flower basket tie rods of the cantilever scaffold, and it is rather troublesome and laborious to reach out for installation.

[0005] 2. Since there are many diagonal tie rods in the bracket during the construction process, there is a working condition where the upper end of the tie rod is fixed in a small space. It is rather troublesome that the tool is easily blocked when approaching the nut, resulting in inconvenience in clamping the nut of the flower basket tie rod of the cantilever scaffold and disassembling it, seriously affecting the construction efficiency.

[0006] Therefore, the utility model provides a tool for installing and disassembling the flower basket tie rods of a cantilever scaffold to solve the problems existing in the above-mentioned prior art. Summary of the Utility Model

[0038] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0039] Please refer to Figures 1-6 , the present utility model provides a technical solution:

[0040] A disassembling and assembling tool for the flower basket tie rod of a cantilever scaffold, comprising:

[0041] A mounting base 1, on the surface of which two symmetrically arranged mounting blocks 2 are fixedly connected;

[0042] A long and short adjustment mechanism 3, which is arranged on the lower side of the mounting base 1 and is used to adjust the length of the handheld part;

[0043] A clamping mechanism 4, which is arranged on one side of the mounting base 1 and comprises a mutually adapted movable fitting assembly 401 and a pushing assembly 402, and is used to fit and clamp the nut for convenient use;

[0044] In this embodiment, when tightening and disassembling the bolt of the hanging basket tie rod of the cantilever scaffold with the intrinsically safe disassembly tool, the clamping part of the tool is retracted at this time to facilitate insertion into the use position. When approaching the use position, the clamping part on the surface of the inserted screw rod naturally opens, and then the tool is pressed against the surface of the nut. The pushing component 402 pushes the movable fitting component 401 to clamp the surface of the nut. At this time, rotating the tool can tighten and disassemble the nut. The length of the handheld part of the tool can be adjusted by the length adjustment mechanism 3, and the length can be extended according to requirements to complete the fixation and installation of the outdoor hanging basket tie rod.

[0045] As a preferred embodiment, as Figure 2 , Figure 5 and Figure 6 shown, two groups of the movable fitting components 401 are provided. Each group of the movable fitting components 401 includes a connecting rotating shaft 4013 fixedly connected to the side end of the mounting block 2. A "V"-shaped push rod 4011 is rotatably connected to the surface of the connecting rotating shaft 4013, and a friction plate 4012 is fixedly connected to the surface of the "V"-shaped push rod 4011;

[0046] In this embodiment, when the pushing component 402 moves, the two friction plates 4012 on both sides of the tool are retracted close to each other to facilitate insertion into a narrow use position. When approaching the use position and inserting it on the surface of the steel pipe, since the steel pipe is circular, the surface will push the upper parts of the two "V"-shaped push rods 4011 away from each other and expand. At this time, the clamping part naturally opens. At this time, the tool is more convenient when approaching the tightening position. There is a certain frictional force on the surface of the connecting rotating shaft 4013, which can ensure the stability during use, and at the same time prevent the "V"-shaped push rod 4011 from rotating randomly, facilitating use and being convenient for installing and disassembling the nut of the hanging basket screw rod of the cantilever scaffold during use.

[0047] As a preferred embodiment, as Figure 2 , Figure 5 and 6 shown, the pushing component 402 includes a pushing plate 4024 slidably connected to the surface of the mounting seat 1, and a contact block 4023 is fixedly connected to the upper end of the pushing plate 4024;

[0048] In this embodiment, when the tool is located on the surface of the nut, the contact block 4023 is pressed against the surface of the nut at this time. Then the contact block 4023 pushes the pushing plate 4024 to squeeze the two "V"-shaped push rods 4011. The approaching surfaces of the two "V"-shaped push rods 4011 are inclined surfaces extending close to each other. The pushing plate 4024 is in contact with the approaching ends of the two "V"-shaped push rods 4011. At this time, the two "V"-shaped push rods 4011 are pushed by the inclined surface of the pushing plate 4024, and the lower parts are away from each other and the upper parts are close to each other and fit against the surface of the nut to clamp and fix the nut; at this time, the nut can be fixed or disassembled by rotating the length adjustment mechanism 3.

[0049] As a preferred embodiment, as Figure 2 、 Figure 5 and 6 shown, a second limiting groove 4021 is further formed in the upper end of the mounting base 1, a second limiting rod 4022 is slidably connected to the inner wall of the second limiting groove 4021, and the upper end of the second limiting rod 4022 is fixedly connected to a contact block 4023;

[0050] In this embodiment, when the push plate 4024 pushes the "V"-shaped push rod 4011 to rotate, the push plate 4024 is prone to skew. By driving the second limiting rod 4022 to slide in the second limiting groove 4021 when the push plate 4024 slides, the push plate 4024 is not prone to skew and is more stable when sliding.

[0051] As a preferred embodiment, as Figure 2 、 Figure 3 and Figure 4 shown, the length adjustment mechanism 3 includes a plurality of splicing seats 308 and a fixed seat 307 fixedly connected to the lower end of the mounting base 1. Insertion grooves 302 are formed in the lower ends of the fixed seat 307 and the plurality of splicing seats 308. Insertion plates 301 are fixedly connected to the upper ends of the plurality of splicing seats 308, and the plurality of insertion plates 301 are respectively slidably connected to the inner walls of the plurality of insertion grooves 302;

[0052] In this embodiment, when it is necessary to extend the length of the installation and disassembly tool, at this time, the insertion plate 301 on the upper side of the splicing seat 308 is inserted into the insertion groove 302 to extend the length until the appropriate use distance.

[0053] As a preferred embodiment, as Figure 2 、 Figure 3 and Figure 4 shown, a fastening nut 304 is further fixedly connected to the inner wall of the insertion plate 301, and a fastening bolt 303 is threadedly connected to the inner wall of the fastening nut 304;

[0054] In this embodiment, the fixed seat 307 and the plurality of splicing seats 308 are both rotatably connected to the fastening bolt 303. Just inserting the insertion plate 301 into the insertion groove 302 is likely to become loose during connection. At this time, the insertion plate 301 and the insertion groove 302 are fixedly connected by the fastening bolt 303, making it more stable during use and not prone to loosening.

[0055] As a preferred embodiment, as Figure 2 、 Figure 3 and Figure 4As shown, first limiting grooves 306 are formed at the lower ends of the fixing base 307 and the plurality of splicing bases 308, and first limiting rods 305 are fixedly connected to the upper ends of the plurality of splicing bases 308. The plurality of first limiting rods 305 are respectively in sliding fit with the plurality of first limiting grooves 306;

[0056] In this embodiment, after the insertion plate 301 and the insertion groove 302 are connected, shaking is likely to occur. Through the sliding fit between the first limiting rod 305 and the first limiting groove 306, the splicing bases 308 are not easy to shake during splicing and are more stable.

[0057] When the cantilever scaffold flower basket tie rod installation and disassembly tool of the present utility model is in use:

[0058] When the scaffold nut is fixed by this installation and disassembly tool, the two friction plates 4012 of this installation and disassembly tool are contracted and approached to facilitate insertion into a narrow use position. When approaching the use position, it is inserted on the surface of the steel pipe. Since the steel pipe is circular, the surface will push the upper parts of the two "V" - shaped push rods 4011 away from each other to expand. At this time, the clamping part naturally opens. Then the contact block 4023 is abutted against the surface of the nut. Then the contact block 4023 pushes the push plate 4024 to squeeze the "V" - shaped push rod 4011. The two "V" - shaped push rods 4011 are pushed by the inclined surface of the push plate 4024, the lower parts are away from each other, and the upper parts are close to and fit the surface of the nut to clamp and fix the nut. At this time, the length - adjusting mechanism 3 can be rotated to fix or disassemble the nut. When it is necessary to extend the length of this installation and disassembly tool, at this time, the insertion plate 301 on the upper side of the splicing base 308 is inserted into the insertion groove 302 to extend the length until the appropriate use distance, and then the insertion plate 301 and the insertion groove 302 are fixedly connected by the fastening bolt 303. At this time, the length extension is completed.

[0059] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non - exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
