[0018] To make the technical means, creative features, objectives and effects of this utility model easy to understand, the following embodiments, in conjunction with the accompanying drawings, will specifically illustrate the technical solution of this utility model.
[0019] See Figure 1 This embodiment provides a mobile air supply trolley split device, which includes a trolley 2 and an air supply mounting frame 1 that is detachably mounted on top of the trolley.
[0020] The gas supply source mounting frame 1 is used for installing the gas supply source (not shown in the figure). The gas supply source is a conventional gas supply source, which includes a gas cylinder, a gas supply pipe, a gas supply valve, and an equipment box, etc. See also Figure 2 The gas supply source mounting frame 1 has a double-layer frame structure. The upper frame has an upper base plate 12, upper side plates 13, and upper horizontal pipes 14, while the lower frame has a lower base plate 15. The upper base plate 12 consists of two pieces. The upper frame is used to hold the gas cylinder. The two upper horizontal pipes 14 in the horizontal direction and the two upper side plates 13 in the vertical direction act as limiters to prevent the gas cylinder from falling. The upper side plates 13 have circular through holes 16 and multiple screw holes 17 distributed around the circular through holes. These circular through holes 16 and screw holes 17 can be used for installing gas supply pipes and flanges. The lower base plate 15 consists of two pieces, corresponding to the upper base plate 12, with a gap between the two lower base plates 15.
[0021] See Figure 2 The trolley 2 includes a trolley base 21 and a trolley handle 22. A set of directional wheels 23 are installed on the lower front side of the trolley base 21. A set of self-locking caster wheels 24 are installed on the lower rear side of the trolley base 21.
[0022] A set of limiting angle irons 25 is installed on the rear side of the trolley base plate 21. This set of limiting angle irons 25 consists of two limiting angle irons 25 vertically fixed to the trolley base plate 21. See also Figure 1 The distance between the two limiting angle irons 25 is adapted to the longitudinal width dimension of the air supply source mounting frame 1, and is used to limit the longitudinal movement of the air supply source mounting frame 1.
[0023] The trolley base plate 21 is also provided with bolt mounting holes 26. There are at least two bolt mounting holes 26, and all bolt mounting holes 26 are distributed in the gap between the two corresponding lower base plates 15. The wing bolts 3 are inserted into the corresponding bolt mounting holes 26 through the gap, so that the air supply source mounting frame 1 is bolted and fixed to the trolley, realizing the detachability of the two. In this embodiment, the wing bolts 3 are M8 wing bolts, and there are two of them.
[0024] See Figure 1 and Figure 2The gas supply source mounting frame 1 is equipped with a frame handle 11, and the frame handle 11 and the trolley handle 22 have the same structure and are symmetrically arranged. The frame handle 11 is located on the front side of the trolley, and the trolley handle 22 is located on the rear side of the trolley. The double-layer frame structure and the frame handle 11 are integral structures welded together.
[0025] In this embodiment, the air supply source mounting frame 1 is a welded component consisting of a round tube with a diameter of 22mm and a wall thickness of 1.5mm and a bent plate with a thickness of 3mm.
[0026] In this embodiment, the trolley 2 is a welded component composed of a round tube, a flat plate, and an angle iron. The round tube has a diameter of 22mm and a wall thickness of 1.5mm. The flat plate is a 3mm thick steel plate. The angle iron has dimensions of 25mm × 25mm and a thickness of 3mm.
[0027] In this embodiment, the mobile air supply trolley split device can be operated by removing two M8 disc bolts as needed to separate the upper air supply mounting frame 1 from the lower trolley 2. After the trolley is taken out, it can be used for trolley transportation.
[0028] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
