Description

Technical Field

[0001] This utility model relates to the field of confined space training technology, and in particular to a confined space training workstation. Background Technology

[0002] A confined space is a closed or partially enclosed space that is not designed as a fixed workplace, but is accessible to personnel and can easily lead to the accumulation of toxic, hazardous, flammable, or explosive substances, or insufficient oxygen levels. Compared to working in open spaces, working in confined spaces typically presents challenges such as restricted movement and a higher accident rate. Personnel entering confined spaces for work or rescue operations require adequate training to reduce the occurrence of accidents. To meet this training need, dedicated confined space training stations exist.

[0003] In existing technologies, confined space training stations use a roof or frame as the main support structure, and within it are simulated confined spaces that can be entered horizontally or vertically. Trainees enter these simulated confined spaces to perform simulated tasks, and their work is recorded. As shown in patents with publication numbers CN217213977U and CN220509561U, this type of design structure is basically adopted.

[0004] However, common confined space training stations are mostly monolithic structures or structures fixed with numerous bolts, making them inconvenient to disassemble and transport. Therefore, they are usually permanently built within confined space training bases. Due to the insufficient number of confined space training bases, many personnel cannot receive timely training at these bases, resulting in many workers performing tasks without mastering the necessary skills, leading to a still relatively high accident rate. Utility Model Content

[0005] The purpose of this utility model is to provide a mobile training workstation in a confined space, whose main body is easy to disassemble and transport, so as to solve the problem that personnel cannot go to the base for training in a timely manner.

[0006] To achieve the above objectives, a confined space mobile training workstation is provided, comprising: a supporting body including a bottom crossbeam, a top crossbeam, columns, and internal support beams; four bottom and top crossbeams arranged in a rectangular pattern; columns positioned between adjacent bottom crossbeams, with the tops of the columns located between adjacent top crossbeams; and an internal support beam positioned between two parallel top crossbeams. Tubes are provided on the bottom, top, columns, and internal support beams, and the bottom, top, and internal support beams are detachably connected via longitudinally movable insert structures; a guardrail positioned on the top of the supporting body; a staircase positioned on one side of the supporting body; a ladder assembly detachably connected to the top and internal support beams; and a transverse rescue frame detachably connected to the columns, bottom, and top crossbeams.

[0007] According to the confined space mobile training workstation, the insertion structure includes a female wedge and a male wedge inserted into the female wedge.

[0008] According to the confined space mobile training workstation described above, the internal support beams are configured as multiple beams arranged at intervals.

[0009] According to the confined space mobile training workstation, the ladder assembly includes: a first ladder crossbar, which is vertically installed on the top of the inner support beam and detachably connected to the pipe body on the inner support beam through a pipe fastener; the first ladder crossbar is configured as two parallel ones; a second ladder crossbar, which is fixedly connected to the two first ladder crossbars at both ends; and a ladder body, which is fixedly installed at the bottom of the second ladder crossbar and arranged vertically.

[0010] According to the confined space mobile training workstation, the end of the first ladder crossbar is detachably connected to the pipe on the top crossbeam via pipe fasteners.

[0011] According to the confined space mobile training workstation, the horizontal rescue frame includes: a first horizontal bar, disposed at the top of the bottom horizontal beam and detachably connected to the pipe body on the bottom horizontal beam via pipe fasteners; a second horizontal bar, disposed parallel above the first horizontal bar; a first vertical bar, fixedly connected to one end of the first horizontal bar and the second horizontal bar respectively; a second vertical bar, fixedly connected at both ends to the first horizontal bar and the second horizontal bar respectively; and a sliding frame, fixedly connected to the second horizontal bar.

[0012] According to the confined space mobile training workstation, the other ends of the first and second horizontal bars are detachably connected to the pipes on the uprights via pipe fasteners; the upper end of the first vertical bar is detachably connected to the pipes on the top crossbeam via pipe fasteners.

[0013] According to the confined space mobile training workstation, the sliding frame includes: a sliding bar, which is arranged horizontally and whose middle part is fixedly connected to a second horizontal bar; a third vertical bar, whose bottom is fixedly connected to the sliding bar and whose top is detachably connected to the pipe on the top horizontal beam through a pipe fastener; and a pull rod, which is arranged in a triangle with the sliding bar and the third vertical bar, and whose two ends are fixedly connected to the sliding bar and the third vertical bar respectively.

[0014] Beneficial effects: As described above, the bottom crossbeam and the column, the top crossbeam and the column, and the top crossbeam and the inner support beam are all detachably connected by a longitudinally movable and separable insert structure, which makes the assembly and disassembly of the load-bearing body convenient. Moreover, the size of the individual components after disassembly is small, which is convenient for transportation by truck. It can be flexibly transported to various factories and places where workers are concentrated for confined space operation / rescue training, effectively solving the problems of insufficient number of training bases and the inability of personnel to go to the base for training in a timely manner.
