Description

Technical Field

[0001] This utility model relates to the technical field of float glass equipment, and in particular to a lifting device for changing the head of a float glass suspended edge-pulling machine. Background Technology

[0002] In float glass production lines, lifting equipment is required to disassemble, install, maintain, or replace structural components such as edge rollers, bearings, and transmission mechanisms in the machine head section.

[0003] Because stable and accurate lifting and lowering are required during equipment maintenance and replacement, the most common methods are hydraulic and mechanical. Hydraulic systems offer greater power, are relatively easier to operate, and provide smooth lifting. They are usually equipped with pressure relief valves and pressure holding valves, but they suffer from complex structures and large equipment size and weight. Mechanical systems mostly use screw and nut mechanisms, such as trapezoidal threads or ball screws, to achieve lifting and lowering by turning the screw with a handle or wrench. However, they are slower and require more effort to operate under heavy loads. Utility Model Content

[0004] Therefore, there is a need to provide a lifting device for changing the head of a float glass suspended edge-pulling machine, which can solve the problems of complex hydraulic structure, large equipment size and weight, slow mechanical speed of screw and nut mechanism, and laborious operation under heavy load in the existing technology.

[0005] To achieve the above objectives, this utility model provides a lifting device for changing the head of a float glass suspended edge-pulling machine, including a base, a first support column, a second support column, a bracket, a lateral displacement rod, a lever lifting frame, and a displacement frame;

[0006] The first support column is connected to the upper part of the base, and the side of the first support column is provided with an extension;

[0007] The second support column is sleeved on the inner or outer side of the first support part. The second support column includes an assembly hole and a plug-in fixing rod. The assembly hole is set along the height direction of the second support column. The plug-in fixing rod is assembled on the assembly hole. Both ends of the plug-in fixing rod extend outward from the second support column, and the lower part of the plug-in fixing rod at the bottom faces the top of the first support column.

[0008] The bracket is connected to the upper part of the second support column;

[0009] One end of the lateral displacement rod is hinged to the extension of the first support column;

[0010] The lever lifting frame is hinged to the other end of the lateral displacement rod, and one end of the lever lifting frame faces the direction of the second support column;

[0011] The displacement frame is connected to one end of the lever lifting frame facing the second support column. The displacement frame is provided with a lifting part, which is adapted to the plug-in fixing rod.

[0012] In a preferred embodiment of this application, the first support column has a hollow interior, and the second support column is inserted into the inner side of the first support column. By making the first support column hollow and inserting the second support column into the inner side of the first support column, the weight of the second support column is reduced and the center of gravity of the overall equipment is lowered, which facilitates the lifting and lowering of the second support column and the stability of the overall equipment.

[0013] In a preferred embodiment of this application, the top of the second support column is rotatably connected to the bracket via a plug-in post. By providing a rotatable connection between the top of the second support column and the bracket via a plug-in post, the bracket can be quickly aligned and matched using this rotatable connection method, and brackets with compatible structures can be replaced.

[0014] In a preferred embodiment of this application, the length from the hinge point between the lever lifting frame and the lateral displacement rod to the end of the lever lifting frame equipped with the displacement rod is less than the length from the hinge point between the lever lifting frame and the lateral displacement rod to the other end of the lever lifting frame. By using a lateral displacement rod for hinge connection, it is convenient to allow the lever lifting frame to be moved aside and to support it in a raised state.

[0015] In a preferred embodiment of this application, the displacement frame includes two forks, each with a lifting portion. By providing two forks, each with a lifting portion, it facilitates the repositioning of the first and second support columns.

[0016] In a preferred embodiment of this application, the lever lifting frame further includes an extension rod, and the lever lifting frame is provided with a insertion hole, into which the extension rod is inserted. By providing the extension rod and the insertion hole, it is convenient to use extension rods of different lengths for support structures of different weights.

[0017] In a preferred embodiment of this application, the second support column is provided with a blocking plate, the bottom of which faces the top of the first lifting column. By providing the blocking plate, the lowest descent position of the second support column is limited, preventing the second support column from retracting into the inside of the first lifting column or damaging the structure on the outside of the first lifting column.

[0018] In a preferred embodiment of this application, the base has a cross-shaped structure. By setting the base to a cross-shaped structure, it is convenient for the base to provide support in multiple directions.

[0019] In a preferred embodiment of this application, the lifting portion is a groove structure. By providing a groove structure for the lifting portion, it is easier to adapt to the outer shape of the plug-in post.

[0020] In a preferred embodiment of this application, the extension of the first support column is provided with two or more hinge areas, and the lateral displacement rod can be selectively hinged to any of these hinge areas. By providing two or more hinge areas on the extension of the first support column, it is convenient to adapt and install for forks and lifting rods of different sizes, allowing the lever lifting frame and the lateral displacement rod to tilt in the appropriate position.

[0021] Unlike existing technologies, the above technical solution has the following advantages: by setting an extension on one side of the first support column, and cooperating with the lateral displacement rod to drive the lever lifting frame, in the lateral direction of the first lifting column, the displacement frame contacts the plug-in fixing rod of the second support column. The lever lifting frame uses the lever principle to lift the second support column quickly and effortlessly. Then, the height is limited by the newly connected plug-in fixing rod. Compared with the hydraulic lifting rod, the structure is simplified, no external power source is required, and the lifting efficiency is improved compared with the screw-type lifting mechanism. It is convenient for operators to use and move at any time to perform lifting and lowering operations at a specified height. Attached Figure Description

[0049] Please see Figures 1 to 5 This utility model provides a lifting device for changing the machine head of a float glass suspended edge-pulling machine, including a base 10, a first support column 20, a second support column 30, a bracket 40, a lateral displacement rod 50, a lever lifting frame 60 and a displacement frame 70.

[0050] The first support column 20 is connected to the upper part of the base 10, and the first support column 20 has an extension 21 on its side;

[0051] The second support column 30 is sleeved on the inner or outer side of the first support part. The second support column 30 includes an assembly hole 31 and a plug-in fixing rod 32. The assembly hole 31 is arranged along the height direction of the second support column 30. The plug-in fixing rod 32 is assembled on the assembly hole 31. Both ends of the plug-in fixing rod 32 extend outward from the second support column 30, and the lower part of the plug-in fixing rod 32 at the bottom faces the top of the first support column 20.

[0052] The bracket 40 is connected to the upper part of the second support column 30;

[0053] One end of the lateral displacement rod 50 is hinged to the extension 21 of the first support column 20.

[0054] The lever lifting frame 60 is hinged to the other end of the lateral displacement rod 50, and one end of the lever lifting frame 60 faces the direction of the second support column 30;

[0055] The displacement frame 70 is connected to one end of the lever lifting frame 60 facing the second support column 30. The displacement frame 70 is provided with a lifting part 71, which is adapted to the plug-in fixing rod 32.

[0056] According to the above structure, during the use of the lifting device for changing the head of the float glass suspended edge-pulling machine, the operator moves the lifting device to below the head to be processed, raises the second support column 30, and the bracket 40 first contacts the head to be processed. The insertion fixing rod 32 is then inserted into the assembly hole 31 at the specified height of the second support column 30, and the insertion fixing rod 32 contacts the first support column 20, maintaining the relative height between the second support column 30 and the first support column 20, thus completing the initial height fixation. When lifting is required, the operator grasps the lever lifting frame 60, driving the lateral displacement rod 50, so that the displacement frame 70 reaches the area where the insertion fixing rod 32 is located and contacts the area below the insertion fixing rod 32. The operator then presses down the lever lifting frame 60. The displacement frame 70 uses the hinge point between the lateral displacement rod 50 and the lever lifting frame 60 as the fulcrum, lifting the displacement frame 70. This causes the displacement frame 70 to drive the insertion fixing rod 32, which in turn drives the second support column 30, the bracket 40, and the machine head equipment to rise. After reaching the designated height, a new insertion fixing rod 32 is inserted into the mounting hole 31 at the new height. The new insertion fixing rod 32 contacts the first support column 20, keeping the second support column 30 at the new height. The lifting operation is completed by repeating the lifting process once or multiple times.

[0057] When lowering is required, the displacement frame 70 contacts the second insertion fixing rod 32 from the bottom, lifting the insertion fixing rod 32 so that the lowest insertion fixing rod 32 is removed from the first support column 20. Then, the insertion fixing rod 32 in contact with the displacement frame 70 is lowered, bringing it into contact with the top of the first support column 20, completing a single lowering operation. The lowering operation is completed by repeating the lowering process once or multiple times. This allows for further processing of the raised and lowered machine head structure.

[0058] By setting an extension 21 on one side of the first support column 20, and cooperating with the lateral displacement rod 50 to drive the lever lifting frame 60, in the lateral direction of the first lifting column, the displacement frame 70 contacts the plug-in fixing rod 32 of the second support column 30. The lever lifting frame 60 uses the lever principle to lift the second support column 30 quickly and effortlessly. Then, the newly connected plug-in fixing rod 32 is used to limit the height. Compared with the hydraulic lifting rod, the structure is simplified, no external power source is required, and the lifting efficiency is improved compared with the screw-type lifting mechanism. It is convenient for operators to use and move at any time to perform lifting and lowering at a specified height.

[0059] Please see Figures 1 to 5 In a preferred embodiment of this application, the first support column 20 has a hollow interior, and the second support column 30 is inserted into the inner side of the first support column 20.

[0060] Please see Figures 1 to 5 In a preferred embodiment of this application, the top of the second support column 30 is rotatably connected to the bracket 40 via a plug-in post 41. By providing a rotatable connection between the top of the second support column 30 and the bracket 40 via the plug-in post 41, the bracket 40 can be quickly aligned and replaced with a suitable structure using this rotatable connection. During use, different support structures of the bracket 40 can be replaced for different machine head structures, and the angle can be adjusted during lifting. The plug-in post 41 can be fixed via a pre-set mating hole on the top of the second support column 30; in other embodiments, a threaded hole and a threaded rod can also be used for mating.

[0061] Please see Figures 1 to 5In a preferred embodiment of this application, the length from the hinge point of the lever lifting frame 60 and the lateral displacement rod 50 to the end of the lever lifting frame equipped with the displacement frame 70 is less than the length from the hinge point of the lever lifting frame 60 and the lateral displacement rod 50 to the other end of the lever lifting frame 60. By providing the lateral displacement rod 50 for hinge connection, it is convenient to allow the lever lifting frame 60 to be moved aside and to support it in a raised state.

[0062] Please see Figures 1 to 5 In a preferred embodiment of this application, the displacement frame 70 includes two forks, each fork having a lifting part 71.

[0065] Please see Figures 1 to 5 In a preferred embodiment of this application, the base 10 has a cross-shaped structure. By setting the base 10 to a cross-shaped structure, it is convenient for the base 10 to provide support in multiple directions. In other embodiments, the base 10 can also be rectangular or circular.
