Description

Technical Field

[0001] The utility model relates to the field of metal casting, in particular to a safety rail pressing device for adding and uncovering a cover of an unpowered molten iron tank. Background Art

[0002] At present, due to the increasing requirements of environmental protection and energy conservation in steel enterprises, various steel enterprises have successively installed molten iron tank capping devices in the transportation of molten iron, so as to achieve the effect of environmental protection and energy conservation by covering the entire molten iron transportation. The unpowered molten iron tank capping device is a new type of capping structure that has emerged in recent years. For example, the invention patent with application number 202310039267.0 and invention name is a fixed-point ramp-driven molten iron tank capping device and method. Its main feature is that the mechanical connecting rod drives the rotating arm with the help of the ground device beside the track to realize the rotation, and then drives the tank cover to realize the function of opening and closing the cover. During the use of the unpowered molten iron tank capping device, especially when closing the cover, a large upward lifting force is required to complete the closing action. Since the entire set of capping devices is fixedly connected to the molten iron frame, this lifting force will also act on the molten iron frame at the same time, so that the molten iron frame has a certain risk of tipping over, and there is a huge safety hazard that needs to be solved urgently.

[0003] The current solution for the production line of the enterprise is to add a buffer device under the rotating arm, that is, by adding a buffer device under the arm on both sides to reduce the gravity moment of the arm when the cover is open, thereby reducing the upward lifting force and reducing the risk of the molten iron frame tipping over. Although the upward lifting force can be reduced by adding a buffer device, when other mechanical obstructions occur and the movement is not smooth, the lifting force will suddenly increase a lot, which cannot fundamentally solve the problem of the molten iron frame tipping over, is not conducive to the user's operation and safe use, and is not conducive to the development of the enterprise.

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0021] like Figure 1-Figure 3 As shown, an embodiment of the utility model proposes a safety rail-holding device for adding a cover to an unpowered molten iron ladle, comprising a bottom beam 8, an upper pressure beam 3, a column 5 and a pressure wheel 9. The bottom beam 8 is fixedly installed on one side of the ground ramp of the unpowered molten iron ladle adding a cover, and the upper end of the bottom beam 8 is vertically connected to at least two columns 5; the upper end of each column 5 is vertically connected to the upper pressure beam 3, and a rail-holding panel 2 is installed on one side of the upper pressure beam 3; the pressure wheel 9 is connected to the side of the molten iron frame that is biased toward the rail-holding panel 2; the rail-holding panel 2 is used to limit the height of the pressure wheel 9.

[0022] When the tank car frame equipped with the non-powered capping device passes through the ground ramp to perform the closing or opening action, the top height of the pressure wheel 9 on the molten iron car frame needs to be slightly lower than the height of the bottom end surface of the rail pressure panel 2. The pressure wheel 9 first enters the lower side of the rail pressure panel 2 at one end of the upper pressure beam 3, and then as the molten iron tank frame car continues to move forward, the pressure wheel 9 moves along the bottom of the rail pressure panel 2. After that, the molten iron tank frame car continues to move forward until the entire closing or opening action is completely performed. During the whole process, the pressure wheel 9 is always under the rail pressure panel 2, and finally the pressure wheel 9 leaves along the other end of the upper pressure beam 3. During the process of closing or opening the cover, if the capping device is blocked and not smooth, at this time, due to the sudden increase in the upward lifting force of the capping device, the pressure wheel 9 will be tightly pressed upward on the rail pressure panel 2 and move along the rail pressure panel 2. Since the pressure wheel 9 is always under the upper pressure beam 3, it can effectively and directly prevent the molten iron car frame from tipping over, eliminating the risk of the molten iron car frame tipping over.

[0023] The utility model discloses a safety rail pressing device for adding a cover to an unpowered molten iron tank, which is matched and installed on one side of a ground ramp of the unpowered molten iron tank adding a cover. The height of the rail pressing panel 2 is set corresponding to the height of the pressing wheel 9. The height of the molten iron frame is limited by limiting the height of the pressing wheel 9, so as to prevent the molten iron frame from tipping over due to excessive height on one side. The utility model fundamentally adds a safety measure for the use of the unpowered molten iron tank adding a cover. The overall device has a simple structure, a reasonable and ingenious design, is easy to install, use and maintain, has a low manufacturing cost, and solves important safety issues in the production process of an enterprise.

[0024] In some embodiments, Figure 2 As shown, a plurality of brackets 10 are vertically connected to the side of the bottom beam 8 that is biased toward the ground, and a diagonal support column 4 is further connected between the bracket 10 and the upper pressure beam 3; the plurality of brackets 10 are arranged in parallel to each other, and each group of brackets 10, diagonal support columns 4 and columns 5 respectively constitute a triangular stable and solid support structure. If the covering device is stuck or not smooth during the closing or opening of the cover, the upward lifting force of the covering device suddenly increases, and the pressure wheel 9 will be tightly pressed upward on the rail pressure panel 2. The plurality of brackets 10 arranged in parallel to each other and the triangular structure formed by multiple groups of brackets 10, diagonal support columns 4 and columns 5 form a rigid frame structure of the device, and utilize multi-point dispersed support and the principle of triangular stability to prevent the device from deformation or shaking, so as to balance the force acting on the rail pressure panel 2 and maintain the stability of the overall device.

[0025] In some embodiments, the bottom beam 8 and each column 5, and the bracket 10 and the diagonal support column 4 are respectively connected by adjustable nuts 7. By adjusting the adjustable nuts 7, the height of the column 5 and the diagonal support column 4 can be adjusted, thereby adjusting the height of the upper pressure beam 3 and the rail pressure panel 2 to match the height of the pressure wheel 9 installed on different actual molten iron carriages, thereby improving the applicability of the device.

[0026] Further optionally, a pad 6 is detachably connected between the bottom beam 8 and each column 5, and between the bracket 10 and the diagonal support column 4. The pad 6 is connected to the bracket 10 and the diagonal support column 4 respectively through an adjustable nut 7. The pad 6 can be selected with different thicknesses according to the height requirements of the upper pressure beam 3 and the rail pressure panel 2. By adding the pad 6, the height of the pressure wheel 9 installed on different types of molten iron carriages can be met, further expanding the scope of application of the device.

[0027] Since the molten iron ladle trolley is in a continuous moving state during the covering process, in order to prevent the pressure wheel 9 from colliding with the upper pressure beam 3 when entering the range of the upper pressure beam 3 and the upper pressure beam 3 from blocking the pressure wheel 9 when it is about to leave the range of the upper pressure beam 3, preferably, the upper pressure beam 3 is provided with forward guide slopes 1 at both ends along the moving direction of the molten iron ladle. The forward guide slope 1 is buffered by the slope, so that the pressure wheel 9 can smoothly enter or leave the range of the upper pressure beam 3, thereby avoiding the upper pressure beam 3 from blocking the pressure wheel 9 and affecting the normal operation of the covering process.

[0028] Preferably, the rail pressing panel 2 is a panel made of wear-resistant material, such as wear-resistant steel plate, wear-resistant rubber, etc.

[0029] The utility model is used for the safety rail pressing device for unpowered molten iron tank cover. When used in the process of covering, the pad 6 is connected to the bracket 10 and the diagonal support column 4 respectively through the adjustable nut 7, and the height of the upper pressure beam 3 and the rail pressing panel 2 is adjusted to match the height of the pressure wheel 9 installed on different molten iron vehicle frames. When the tank vehicle frame equipped with the unpowered covering device passes through the ground ramp to perform the cover closing or cover opening action, the pressure wheel 9 on the molten iron vehicle frame first enters the forward guide slope 1 at one end of the upper pressure beam 3, and then as the molten iron tank frame vehicle continues to move forward, the pressure wheel 9 enters the lower side of the rail pressing panel 2 along the forward guide slope 1, and then as the molten iron tank frame vehicle continues to move forward, the pressure wheel 9 moves under the rail pressing panel 2, and then the molten iron tank frame vehicle continues to move forward until the entire cover closing or cover opening action is completely performed. During the whole process, the pressure wheel 9 is always below the rail pressing panel 2, and finally the pressure wheel 9 leaves along the forward guide slope 1 at the other end of the upper pressure beam 3. If the covering device is stuck or not smooth during the process of closing or opening the cover, the upward lifting force of the covering device suddenly increases, and the pressure wheel 9 will be tightly pressed upward on the track pressing panel 2 of the upper pressure beam 3 and move along the track pressing panel 2. Since the pressure wheel 9 is always under the upper pressure beam 3, it can effectively and directly prevent the molten iron frame from tipping over, eliminating the risk of the molten iron frame tipping over.

[0030] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
