[0035] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0036] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0037] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0038] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] As shown in the figure, the oxygen gun transverse trolley positioning device of the present invention is mainly composed of an electro-hydraulic push rod 1, whose head is connected to a positioning rod 3, on which a guide roller 4 and a positioning roller 6 are sleeved, and the above components are supported on an electro-hydraulic push rod bracket 2 through the electro-hydraulic push rod 1; the guide roller 4 slides up and down in a guide groove 5, which is fixed on a positioning roller support 7, and buffer pads 9 are arranged on both sides of the positioning roller support 7; a positioning plate 8 is connected to the transverse trolley frame, on which a buffer pad 9 and a positioning groove of a trumpet-shaped U-shaped groove structure for embedding the positioning roller 6 are arranged; a stroke control switch 10 for controlling the stroke of the electro-hydraulic push rod 1 is welded to the positioning roller support 7 through a stroke control switch bracket 11, and a sensing frame 12 for sensing the stroke control switch is sleeved on the positioning rod 3.

[0040] according to Figure 3 As shown, the trolley moves to the left, triggering the trolley travel switch. The trolley travel switch sends a signal to the trolley motor to cut off the power, and the trolley is brought to the positioning plate to the position O1 shown in the figure. Due to inertia, the trolley continues to move to the left. Figure 2 The buffer pad on the positioning plate shown in FIG. contacts the buffer pad on the positioning rod. The positioning plate is now in Figure 3 The position O3 is shown; at this time, the control system sends a signal to the electro-hydraulic push rod motor of the positioning device, driving the electro-hydraulic push rod head to rise, driving the guide roller to slide along the guide groove, the positioning roller rises quickly, and the outer circle of the positioning roller contacts the bell mouth B1 of the positioning plate. As the positioning roller rises further, the transverse trolley and the positioning plate move together to the right in the opposite direction. After the positioning roller reaches the working stroke, the extension stroke control switch of the electro-hydraulic push rod sends a signal, the electro-hydraulic push rod motor stops, the positioning roller stops rising, and the positioning roller is clamped in the U-shaped groove of the positioning plate. At this point, the transverse trolley and the positioning plate are locked in the O2 position, completing the precise positioning of the transverse trolley. When the transverse trolley moves from left to right, the outer circle of the positioning roller contacts the bell mouth A1 of the positioning plate, and the subsequent actions are the same as before. When the positioning needs to be unlocked, the electro-hydraulic push rod descends, and the reverse operation is also the same.

[0041] Figure 4 FIG. 1 is a schematic diagram of the structure of the oxygen lance lifting and lateral movement system of the present invention. Figure 4As shown, the system at least includes a guide rail installed on the foundation; a transverse moving trolley 18 is arranged on the guide rail; a winch platform is arranged on the transverse moving trolley; a positioning plate 8 is arranged on the side of the transverse moving trolley close to the foundation; and a positioning device 28 adapted to the positioning plate is arranged on the foundation corresponding to the positioning plate.
