Description

Technical Field

[0001] The invention relates to the technical field of steel structure buildings, and in particular to a tool for installing bolts inside a closed component. Background Art

[0002] In the field of steel structure technology, there are often some closed steel components connected. Since it is impossible to place bolts inside the long or sealed square, round, and rectangular tubes, in order to enable the square and rectangular tubes to be connected with other components by bolts, it is usually achieved by welding connecting plates, welding flange plates, adding clamps, etc. on the outside of the tube. This practice not only increases the cost of materials and welding work, but also makes it difficult to accept that the node size is large, difficult to transport and store, extremely unsightly, and the protruding parts are easy to hurt people. Summary of the invention

[0003] The purpose of the present invention is to provide some installation tools and installation methods for effectively installing bolts inside steel components with large lengths or closed ends.

[0004] To achieve the above purpose, the present invention proposes a bolt installation tool for an internal closed component, wherein a working rod is installed at the bottom of an industrial endoscope, and a strong magnetic sleeve is installed at the end of the working rod; the lens of the industrial endoscope is arranged toward the strong magnetic sleeve.

[0005] Furthermore, the working rod is a robotic arm or a metal hose.

[0006] Furthermore, the metal hose is a stainless steel hose.

[0007] Furthermore, the stainless steel hose is sleeved on the outer surface of the endoscope cable, the end of the stainless steel hose is connected to the strong magnetic sleeve, and the lens passes through the side of the stainless steel hose and is arranged toward the strong magnetic sleeve.

[0008] The present invention also proposes a method for installing bolts inside a closed component, by reserving an operating hole on the surface of the closed component, inserting a working rod with the bolt adsorbed on it into the operating hole, and under the guidance of endoscope observation, moving the bolt into the bolt hole in the closed component, screwing the nut from the outside to fix it, and pulling out the working rod to complete the installation.

[0009] Compared with the prior art, the advantages of the present invention are that: by combining the use of an industrial endoscope, the present invention can realize the installation of internal bolts by opening a small working port on the side of a closed or long steel component. It is efficient and the process is simple, and it effectively solves the problems of high cost, unsightly appearance and large workload caused by the use of welding connecting plates or adding clamps in traditional closed components. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 2 is a structural diagram of an industrial endoscope in an embodiment of the present invention.

[0011] Figure 2 It is a schematic diagram of the working state of a bolt installation tool inside a closed component in an embodiment of the present invention. DETAILED DESCRIPTION

[0012] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be further described below.

[0013] like Figure 1 As shown, the present invention proposes a bolt installation tool for the inside of a closed component, which is based on a traditional industrial endoscope 1. A stainless steel metal hose is sleeved on the surface of the endoscope cable of the industrial endoscope 1, and a strong magnetic sleeve 4 is connected to the end of the stainless steel hose 2. The lens 3 passes through the side of the stainless steel hose 2 and is arranged toward the strong magnetic sleeve 4, so as to record the working video of the strong magnetic sleeve 4, thereby accurately grasping the position information of the bolt inside the closed component.

[0014] In order to facilitate the understanding of those skilled in the art, the present invention also proposes a method for installing bolts inside a closed component, such as Figure 2 As shown, it includes a closed steel component 5 and a to-be-connected part 6, and corresponding bolt connection holes are provided on the surfaces of the to-be-connected part 6 and the closed steel component. By reserving an operation hole on the surface of the closed component, inserting a working rod with a bolt adsorbed thereon from the operation hole, and under the guidance of endoscope observation, moving the bolt to the corresponding bolt hole of the closed steel component 5 and the connecting part, and after screwing the nut 7 from the outside to fix it, the working rod is pulled out to complete the bolt connection between the closed steel component 5 and the to-be-connected part 6.

[0015] The above is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any technician in the relevant technical field, without departing from the scope of the technical solution of the present invention, makes any form of equivalent replacement or modification to the technical solution and technical content disclosed in the present invention, which does not depart from the content of the technical solution of the present invention and still falls within the protection scope of the present invention.
