Description

Technical Field

[0001] This invention belongs to the field of special equipment construction technology, specifically, it relates to an auxiliary climbing device. Background Technology

[0002] Special equipment users should conduct regular inspections of special equipment. For mobile containers holding flammable, explosive, combustion-supporting, toxic, or asphyxiating media, preparatory work is required before inspection, including residual liquid treatment, steam purging, ventilation replacement, cleaning, and weld grinding.

[0003] To complete high-altitude operations such as grinding welds inside the container and subsequent inspections, the usual practice is to build a full-span scaffold with couplers inside the container. Building scaffolds in an enclosed space is an extremely dangerous, time-consuming, and labor-intensive task that requires extremely high levels of safety and structural stability.

[0004] Vertical cylindrical pressure vessels have a narrow space and a large height-to-diameter ratio. Due to their unique structural characteristics, it is not suitable to build full-span coupler-type scaffolding.

[0005] To solve the above problems, an auxiliary climbing device is invented that enables construction work to be carried out inside a vertical cylindrical pressure vessel. Summary of the Invention

[0006] In view of the technical problems mentioned above, the present invention aims to provide an auxiliary climbing device that can be built inside a vertical cylindrical pressure vessel, thereby enabling workers to carry out construction work on the inner wall of the vertical cylindrical pressure vessel.

[0007] According to the present invention, an auxiliary climbing device is provided, which is disposed inside a cylindrical container and includes:

[0008] A vertically installed column inside the container;

[0009] Multiple support components are horizontally arranged on the column, and the support components abut against the inner wall of the container by means of telescoping.

[0010] In one specific embodiment, a plurality of the support components are evenly spaced along the axial direction on the column.

[0011] In one specific embodiment, the support component includes:

[0012] Multiple horizontal bars evenly arranged circumferentially on the column; and

[0013] A telescopic component is coaxially mounted on the crossbar, and the telescopic component abuts against the inner wall of the container by extending or retracting.

[0014] In one specific embodiment, an external thread is provided on the outer side of the telescopic member and an internal thread is provided in the crossbar. The external thread of the telescopic member is adapted to the internal thread of the crossbar, and the telescopic member extends and retracts relative to the crossbar through the thread.

[0015] In one specific embodiment, the support assembly further includes a sleeve fixedly disposed on the column, and the crossbar is coaxially disposed within the sleeve.

[0016] In one specific embodiment, a side plate is provided at the end of the telescopic member away from the crossbar, the side plate being used to abut against the inner wall of the container.

[0017] In one specific embodiment, multiple climbing poles are also provided on the column.

[0018] In one specific embodiment, a plurality of the climbing poles are evenly arranged on the column along the axial direction.

[0019] In one specific embodiment, there is a gap between the climbing pole and the inner wall of the container.

[0020] In one specific embodiment, a base plate for contacting the container is provided at the lower end of the column.

[0021] Compared with the prior art, the advantages of this application are as follows.

[0022] Based on the internal structural characteristics of vertical cylindrical pressure vessels, this invention employs multiple horizontal bars evenly distributed on the same layer to prevent the internal construction devices of the vertical cylindrical pressure vessel from twisting, thus eliminating the need for scaffolding. The expansion joint cleverly utilizes threads for adding and removing threads, ensuring the entire support assembly is firmly fixed between the column and the inner wall of the vessel, thus meeting the safety performance requirements of the tool.

[0023] This invention eliminates the need for full-span scaffolding with couplers, features a simple structure, is easy to assemble, can utilize common pipe materials such as seamless steel pipes, has low manufacturing costs, is economically applicable, and can be reused, saving labor and time, and improving the efficiency of pressure vessel inspection and construction.

[0024] This invention takes into account the distribution of stress points of the rods inside the pressure vessel and the arrangement of the upper and lower passage spaces. Under the premise of ensuring safety, it can ensure sufficient load-bearing capacity, save pipe fittings, speed up the erection process, and save construction costs. Attached Figure Description

[0038] The invention will now be described with reference to the accompanying drawings.

[0039] It should be noted that the directional terms or qualifiers such as "up" and "down" used in this application are all specific to the referenced [reference]. Figure 1 In other words, they are not used to define the absolute position of the components involved, but can vary depending on the specific circumstances.

[0040] Figure 1 A schematic diagram of the internal structure of an embodiment of the auxiliary climbing device according to the present invention installed inside a container is shown. Figure 2 A schematic diagram of one embodiment of the assisted climbing device according to the present invention is shown. Figure 3 A schematic diagram of the external structure of an embodiment of the auxiliary climbing device according to the present invention installed inside a container is shown.

[0041] like Figures 1-3 As shown, the auxiliary climbing device 100 is installed inside the cylindrical container 10. The auxiliary climbing device 100 mainly includes a column 1 and a support assembly 2.

[0042] In this embodiment, the axial height of the column 1 is approximately equal to the height of the container 10, and the column 1 is coaxially arranged inside the container 10 in the vertical direction.

[0043] Multiple support components 2 are horizontally mounted on the column 1, and the support components 2 abut against the inner wall of the container 10 through telescopic movement. That is, one end of the support component 2 abuts against the column 1, and the other end abuts against the inner wall of the container 10, thereby fixing the column 1 inside the container 10. At the same time, the support components 2 can also be climbed by workers.

[0044] In one specific embodiment, multiple support components 2 are evenly spaced along the axial direction on the column 1. This arrangement secures the column 1 firmly inside the container 10 from top to bottom, preventing the support components 2 and the column 1 from moving relative to the container 10.

[0045] In one specific embodiment, the support assembly 2 includes crossbars 21 and telescopic members 22. Multiple crossbars 21 are evenly arranged on the column 1 along the circumferential direction. In this embodiment, four crossbars 21 are evenly arranged on the column 1 along the circumferential direction, and the included angle between adjacent crossbars 21 is 90 degrees.

[0046] The telescopic component 22 is coaxially mounted on the crossbar 21, meaning that a telescopic component 22 is provided at the end of each crossbar 21 away from the column 1. The telescopic component 22 abuts against the inner wall of the container 10 by telescoping.

[0047] Specifically, an external thread is provided on the outer side of the telescopic member 22, and an internal thread is provided in the crossbar 21. The external thread of the telescopic member 22 is adapted to the internal thread of the crossbar 21, and the telescopic member 22 extends and retracts relative to the crossbar 21 through the thread. When the telescopic member 22 moves away from the column 1 relative to the crossbar 21 through the thread, the telescopic member 22 can abut against the inner wall of the container 10, thereby fixing both the column 1 and the support assembly 2 inside the container 10.

[0048] According to a specific embodiment of the present invention, the support component 2 further includes a sleeve 23 fixedly disposed on the column 1, and the crossbar 21 is coaxially disposed inside the sleeve 23.

[0049] like Figure 1 and Figure 2 As shown, in this embodiment, one end of the sleeve 23 is fixedly mounted on the outer wall of the column 1, and the central axis of the sleeve 23 is perpendicular to the central axis of the column 1. One end of the crossbar 21 is coaxially inserted into the sleeve 23, and the other end of the crossbar 21 abuts against the inner wall of the container 10 through the telescopic member 22. By setting the sleeve 23, the installation of the crossbar 21 and the telescopic member 22 can be facilitated, and the assembly and disassembly of the auxiliary climbing device 100 can be facilitated, thereby improving efficiency.

[0050] In a preferred embodiment, a side plate 4 is provided at the end of the telescopic member 22 away from the crossbar 21. The side plate 4 is used to abut against the inner wall of the container 10. The side plate 4 can increase the contact area between the telescopic member 22 and the container 10, thereby allowing the auxiliary climbing device 100 to be more stably installed inside the container 10.

[0051] In a preferred embodiment, a plurality of climbing rods 5 are also provided on the column 1. The plurality of climbing rods 5 are evenly spaced along the axial direction on the column 1, and the climbing rods 5 are provided for workers to climb when moving up and down inside the container 10. Alternatively, a plurality of climbing rods 5 are evenly arranged along the axial direction between axially adjacent support components 2, and the climbing rods 5 and the support components 2 together provide for workers to climb when moving up and down inside the container 10.

[0052] In one specific embodiment, there is a gap between the climbing pole 5 and the inner wall of the container 10. That is, one end of the climbing pole 5 is fixed to the outside of the column 1, and the other end of the climbing pole 5 has a gap with the inner wall of the container 10, so that the column 1 can be quickly placed inside the container 10.

[0053] In a preferred embodiment, a base plate 6 is provided at the lower end of the column 1 for contacting the container 10. The base plate 6 increases the contact area between the lower end of the column 1 and the container 10.

[0054] According to a specific embodiment of the present invention, the column 1 is the main load-bearing structure inside the vertical cylindrical pressure vessel 10, and is the main force-bearing component, which determines the stability of the entire structure. It coincides with the central axis of the vertical cylindrical pressure vessel 10, and the base plate 6 is welded to the lower end of the column 1.

[0055] In this embodiment, the column 1 is made of seamless steel pipe with a diameter of Φ114×5. The base plate 6 is made of steel plate with a diameter of 400mm×400mm and a thickness of 16mm.

[0056] In this embodiment, the crossbar 21 is a seamless steel pipe with a diameter of 48×3.5, and the sleeve 23 is a seamless steel pipe with a diameter of 60×4. The sleeve 23 is welded to the column 1. The crossbar 21 is erected perpendicular to the column 1, with one end inserted into the sleeve 23 and connected to the column 1, and the other end connected to the side plate 4 through the telescopic member 22. The function of the telescopic member 22 is to adjust the telescopic amount of the support assembly 2, so that the support assembly 2 is firmly fixed between the column 1 and the container 10.

[0057] In this embodiment, the side plate 4 is made of 400mm×400mm steel plate with a thickness of 16mm. The crossbars 21 bear the weight of the construction workers through the extrusion friction between the side plate 4 and the side wall of the container 10. Each layer of crossbars 21 serves as the working surface for the construction workers. Each layer of crossbars 21 has four crossbars 21 evenly distributed, with an included angle of 90° between two crossbars 21. The distance between two layers of crossbars 21 and between the crossbars and the bottom plate 6 is 1m.

[0058] In this embodiment, the climbing poles 5 are made of Φ20 steel wire with a length of 200mm, and are evenly distributed on both sides of the column 1. They are vertically welded to the column 1. The distance between the climbing poles 5 is 300mm. Their function is to provide handholds and step bars for construction workers to go up and down each layer of horizontal bar 21.

[0059] The installation steps for the auxiliary climbing device 100 inside the container 10 are as follows.

[0060] The column 1, which is welded with sleeve 23, climbing rod 5 and base plate 6, is placed into container 10 through the top manhole.

[0061] Place the crossbar 21, telescopic component 22, and side plate 4 into the container 10. Insert the end of the crossbar 21 into the sleeve 23. Adjust the telescopic length of the telescopic component 22 relative to the crossbar 21 to fix the crossbar 21.
