Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to an oxygen lance anti-falling device. Background Art

[0002] The oxygen lance is a tubular device that blows high-pressure, high-purity oxygen at supersonic speed into the top of the metal pool in the converter and is equipped with a high-pressure water cooling protection system. It is also called a spray gun. It is an important equipment for oxygen top-blowing steelmaking.

[0003] The oxygen lance is one of the main process equipment in oxygen converter steelmaking. Its performance characteristics directly affect the smelting effect and blowing time, thereby affecting the quality and output of steel.

[0004] The oxygen lance anti-falling stop device described in publication number CN217781200U has a buffering anti-falling mechanism. When the oxygen lance falls during use, the moving plate can timely press the pressing block for buffering until the moving plate on the oxygen lance stays between two adjacent pressing blocks to prevent the oxygen lance from falling into the molten pool and causing danger. However, the prior art still has defects:

[0005] 1. The prior art sets a fixed clamping mechanism to cooperate with a buffering and anti-falling mechanism to fix and buffer the oxygen gun, but the setting of more components makes the structure more complicated, increases the floor space and weight, and is inconvenient to use and install and disassemble. At the same time, when the oxygen gun is stuck in the adjacent pressing block, it is necessary to continuously pull the upper or lower pulling ring to remove the oxygen gun, which is very time-consuming and laborious.

[0006] 2. When the oxygen lance falls, the prior art requires multiple buffer mechanisms to buffer it in order to stop the oxygen lance, so that the oxygen lance needs to fall a long distance, which poses a safety hazard. In addition, the oxygen lance cannot be adjusted according to its suspension height, which is not practical enough. Utility Model Content

[0032] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0033] Combined with Figure 1 The utility model is provided with two fixed columns 1 arranged parallel to each other, the bottom of the fixed column 1 is supported by setting a bottom plate 2, a longitudinally arranged T-slot is opened on the front side of the interior of the fixed column 1, and a plurality of evenly distributed card slots 4 are arranged at the rear end of the T-slot for card connection and limiting, two parallel slide rails 6 are arranged between the fixed columns 1, and a lifting trolley 7 is slidably connected to the front end of the slide rail 6, and the front end of the lifting trolley 7 is fixedly connected to a fixed plate 8, and an oxygen gun 9 is carded in the middle of the fixed plate 8, and hanging rings 5.2 are arranged at both ends of the upper part of the fixed plate 8, and the lifting trolley 7 is used to drive the oxygen gun 9 to rise and fall for normal operation.

[0034] An adjusting mechanism 3 is arranged in the T-slot of the fixing column 1, comprising a T-block 3.1, a mounting plate 3.2, a fixing block 3.3, a limiting rod 3.4, a supporting plate 3.5, a supporting frame 3.6 and a handle 3.7. The T-block 3.1 is clamped in the T-slot, and the front end is fixedly connected with the mounting plate 3.2, and the front end of the mounting plate 3.2 is fixedly connected with the fixing block 3.3. A limiting rod 3.4 is passed through the middle of the fixing block 3.3 and inserted into the slot 4 to fix the T-block 3.1 and the mounting plate 3.2. The fixing block 3.3 is rotatably connected with the fixing block 3.3 on both sides. The support plate 3.5 is rotatably connected with the front end of the support plate 3.5 with a support frame 3.6, the support frame 3.6 is L-shaped, the rear end is rotatably connected to the front end of the limit rod 3.4, and the lower end is fixedly connected to the handle 3.7. The handle 3.7 is lifted to control the upper end of the support frame 3.6 to cooperate with the support plate 3.5 to move backward. At the same time, the lower end of the support frame 3.6 drives the limit rod 3.4 to be pulled forward. Under the action of the fixed block 3.3, it will not deviate, so that the lower end of the limit rod 3.4 leaves the slot 4, so that the T-block 3.1 can drive the mounting plate 3.2 to do the lifting movement.

[0035] A clamping mechanism 5 is arranged at the front lower end of the mounting plate 3.2, comprising a pin shaft 5.1, a hook 5.2, a clamping plate 5.3, a clamping rod 5.4 and a cross 5.5. The pin shaft 5.1 is plugged into the front lower end of the mounting plate 3.2 and is close to one side thereof. The middle of the pin shaft 5.1 is rotatably connected with the hook 5.2. The front end of the pin shaft 5.1 is rotatably connected with the clamping plate 5.3. The clamping plate 5.3 is drop-shaped. The clamping plate 5.3 and the hook 5.2 can rotate around the same pin shaft 5.1. The lower end of the clamping plate 5.3 is fixedly connected with a clamping rod 5.4. The clamping rod 5.4 is clamped at one side of the hook 5.2. The middle of the front side of the hook 5.2 is rotatably connected with a cross 5.5. The outer ends of the four support rods of the cross 5.5 are arc-shaped, and the upper support rod is clamped with the clamping rod 5.4, and the lower support rod is clamped with the hanging ring 10.

[0036] When the lifting trolley 7 drives the oxygen lance 9 to be in a normal hanging position, the hanging rings 10 on both sides of the fixing plate 8 are located between the hook 5.2 and the cross 5.5 support rod. When the lifting trolley 7 falls down due to an accident, the hook 5.2 will hook the hanging ring 10, thereby playing a protective role in preventing the oxygen lance from falling; and when the oxygen lance 9 needs to be normally lowered, the lifting trolley 7 first rises slightly upward, the hanging ring 10 pushes the cross 5.5 open, and the support rod at the upper end rotates downward to toggle the card rod 5.4 and the card plate 5.3 to rise until the support rod moves and rotates to the other side of the card rod 5.4 and cooperates with the hook 5.2 for card connection, so that the cross 5.5 cannot rotate downward. At this time, the support rod at the lower end rises at a downwardly inclined angle, and the hanging ring 10 will therefore cut the hook 5.2, thereby realizing the normal descent of the lifting trolley 7. Similarly, when the lifting trolley 7 rises, since the lower part of the hook 5.2 is tilted upward, the hanging ring 10 can directly cut the hook 5.2, so that the lifting trolley 7 rises normally.

[0037] When the utility model is implemented, Figure 1As shown, according to the hanging height of the oxygen gun 9 driven by the lifting trolley 7, the lifting handle 3.7 controls the mounting plate 3.1 to lift and lower the position of the clamping mechanism 5 through the adjusting mechanism 3, and then presses the handle 3.7 to fix it, and rotates the cross 5.5 so that the hanging ring 10 is between the hook 5.2 and the cross 5.5 support rod. When the lifting trolley 7 falls down due to an accident, the hook 5.2 will hook the hanging ring 10, thereby playing a protective role in preventing the oxygen gun from falling; and when the oxygen gun 9 needs to be lowered normally, the lifting trolley 7 first rises slightly upward, and the hanging ring 10 will cross The frame 5.5 is pushed open, and the support rod at the upper end rotates downward to move the clamping rod 5.4 and the clamping plate 5.3 up until the support rod moves and rotates to the other side of the clamping rod 5.4 and cooperates with the hook 5.2 for clamping, so that the cross 5.5 cannot rotate downward. At this time, the support rod at the lower end rises at a downward tilted angle, and the hanging ring 10 will therefore cut the hook 5.2, thereby realizing the normal descent of the lifting trolley 7. Similarly, when the lifting trolley 7 rises, since the lower part of the hook 5.2 is tilted upward, the hanging ring 10 can directly cut the hook 5.2, so that the lifting trolley 7 rises normally.

[0038] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
