Description

Technical Field

[0001] This utility model belongs to the technical field of flange fixing brackets, specifically a flange fixing bracket with automatic leveling. Background Technology

[0002] A flange, also called a flange plate or flange, is a component used to connect shafts, for connecting pipe ends; flanges are also used on equipment inlets and outlets for connecting two pieces of equipment, such as speed reducer flanges. A flange connection or flange joint refers to a detachable connection consisting of a flange, gasket, and bolts connected as a combined sealing structure. Flange mounting brackets are required during installation. Their main function is to ensure that the flange is aligned and securely connected to other components during installation. They are widely used in industries such as petrochemicals, power, and water treatment to support flanges in pipelines, valves, pumps, and other equipment, ensuring the normal operation of the equipment.

[0003] Due to the complexity of flange installation environments, flange mounting brackets are prone to not being level during use. This can lead to loose connections between the flange and other components, affecting sealing and stability. Furthermore, prolonged tilting increases stress on the flange and mounting bracket, potentially causing structural deformation or damage. Existing flange mounting brackets typically require manual leveling, which is time-consuming and inaccurate, easily resulting in problems such as incomplete flange sealing and uneven bolt stress. Summary of the Invention

[0004] Therefore, the purpose of this utility model is to provide a flange fixing bracket with automatic leveling to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a flange fixing frame with automatic leveling, comprising a frame body, a fixing mechanism and a movable groove, wherein the top of the frame body is provided with a movable groove, and the inner side of the movable groove is provided with a fixing mechanism, wherein the fixing mechanism includes a displacement plate movably connected to the movable groove, and a fixing plate is provided on the side of the two displacement plates that are close to each other.

[0006] A support frame is provided at the bottom of the frame, and a leveling mechanism is provided through the inner side of the support frame. The leveling mechanism includes a support column and a rotating shaft connected to the support frame via bearings, and a threaded column connected to the frame via bearings. A fixed gear is provided at the top of the support column, and a moving gear is slidably connected to the side of the rotating shaft near the fixed gear. An electric push rod is installed between the moving gear and the connecting block at one end of the rotating shaft. A support leg is threaded to the outer side of the threaded column, and a level is installed in the middle of the bottom of the frame.

[0007] Preferably, a drive motor is installed on the inner side of the support frame, and the output end of the drive motor is connected to a worm gear through a coupling. A worm wheel sleeved on the outer surface of the support column is engaged with one side of the worm gear.

[0008] Preferably, the moving gear and the electric push rod are set at equal angles.

[0009] Preferably, a bevel gear set is connected between the threaded column and the rotating shaft, and the bevel gear set includes a driving bevel gear connected to the rotating shaft and a driven bevel gear connected to the threaded column.

[0010] Preferably, the support leg has a limiting groove on both sides, and the support frame has a limiting plate on the side near the limiting groove. The support leg and the support frame form a sliding structure through the limiting plate and the limiting groove.

[0011] Preferably, the inner side of the movable groove is rotatably connected to a bidirectional lead screw that is threadedly connected to the displacement plate via a bearing, and both ends of the bidirectional lead screw are provided with limiting blocks that form a sliding structure with the movable groove.

[0012] Preferably, a handle is provided on one side of the bidirectional lead screw, and a bolt is threadedly connected to the inner side of the handle and engaged with a groove on one side of the frame.

[0013] Compared with the prior art, the present invention has the following main advantages:

[0014] This invention uses a level to detect the tilt angle of the frame and the data from the level to control the drive motor and the required electric push rod. Because the moving gear is slidably connected to the rotating shaft, when the electric push rod operates and extends, the moving gear slides along the rotating shaft and meshes with the fixed gear. Simultaneously, the output of the drive motor drives the worm gear to rotate. Because the worm wheel meshes with the worm, it drives the worm wheel, support column, and fixed gear to rotate together. The meshing of the moving gear with the fixed gear causes the moving gear and rotating shaft to rotate, and under the action of the bevel gear set, the threaded column rotates. Because the threaded column is threadedly connected to the support leg, the support leg moves linearly along the threaded column, thereby achieving rapid and accurate adjustment of the support point height, restoring the invention to a level state. This better meets the requirements of high-precision and high-efficiency installation and extends the service life of the invention. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The embodiments of this utility model will be described below based on its overall structure.

[0022] A flange mounting bracket with automatic leveling, such as Figure 1 and Figure 2 As shown, it includes a frame 1, a fixing mechanism 2, and a movable groove 3. The top of the frame 1 has a movable groove 3. The fixing mechanism 2 is provided on the inner side of the movable groove 3. The fixing mechanism 2 includes a displacement plate 202 that is movably connected to the movable groove 3. A fixing plate 203 is provided on the side of the two displacement plates 202 that are close to each other. The inner side of the movable groove 3 is rotatably connected to a bidirectional screw 201 that is threadedly connected to the displacement plate 202 through a bearing. Limiting blocks 8 that form a sliding structure with the movable groove 3 are provided at both the front and rear ends of the bidirectional screw 201.

[0023] See Figure 1 and Figure 2 As can be seen, when the flange is placed between the two fixed plates 203, since the double-acting screw 201 is threadedly connected to the displacement plate 202, the displacement plate 202 can be moved laterally by rotating the handle 204 and the double-acting screw 201, thereby supporting and fixing the flange through the symmetrically arranged fixed plates 203.

[0024] See Figures 1-4It can be seen that a support frame 6 is provided at the bottom of the frame 1, and a leveling mechanism 4 is provided through the inner side of the support frame 6. The leveling mechanism 4 includes a support column 404 and a rotating shaft 407 connected to the support frame 6 through bearings, and a threaded column 410 connected to the frame 1 through bearings. A fixed gear 405 is provided at the top of the support column 404. A moving gear 406 is slidably connected to the side of the rotating shaft 407 near the fixed gear 405. An electric push rod 408 is installed between the moving gear 406 and the connecting block at one end of the rotating shaft 407. A support leg is threadedly connected to the outer side of the threaded column 410. 411, A drive motor 401 is installed on the inner side of the support frame 6. The output end of the drive motor 401 is connected to a worm gear 402 through a coupling. A worm wheel 403 is meshed on one side of the worm gear 402 and sleeved on the outer surface of the support column 404. The moving gear 406 and the electric push rod 408 are set at equal angles. A bevel gear set 409 is connected between the threaded column 410 and the rotating shaft 407. The bevel gear set 409 includes a driving bevel gear connected to the rotating shaft 407 and a driven bevel gear connected to the threaded column 410. A level 5 is installed in the middle of the bottom end of the frame 1.

[0025] See Figures 1-4 It can be seen that the tilt angle of the frame 1 is detected by the level 5, and the data detected by the level 5 controls the operation of the drive motor 401 and the required electric push rod 408. Since the moving gear 406 is slidably connected to the rotating shaft 407, when the electric push rod 408 works and extends, the moving gear 406 slides along the rotating shaft 407 and meshes with the fixed gear 405. At the same time, the output end of the drive motor 401 drives the worm gear 402 to rotate. Since the worm wheel 403 is meshed with the worm gear 402, it drives the worm wheel 403, the support column 404, and the fixed gear 405. The moving gear 406 and the fixed gear 405 mesh together, causing the moving gear 406 and the rotating shaft 407 to rotate. Under the action of the bevel gear set 409, the threaded column 410 rotates. Since the threaded column 410 is threadedly connected to the support leg 411, the support leg 411 moves linearly along the threaded column 410, thereby achieving rapid and accurate adjustment of the support point height, restoring the utility model to a horizontal state, so as to better meet the requirements of high precision and high efficiency installation, and at the same time extend the service life of the utility model.

[0026] See Figure 1 and Figure 4 It is known that limit grooves are provided on both sides of the support leg 411, and a limit plate is provided on the side of the support frame 6 near the limit groove. The support leg 411 and the support frame 6 form a sliding structure through the limit plate and the limit groove, which plays a supporting and limiting role for the support leg 411, so that the support leg 411 only makes linear movement and prevents deviation.

[0027] See Figure 1 and Figure 3It can be seen that a handle 204 is provided on one side of the bidirectional lead screw 201. The inner side of the handle 204 is threaded with a bolt 7 that engages with a groove on one side of the frame 1. When the bolt 7 engages with the groove, the handle 204 can be positioned to prevent the handle 204 from rotating.

[0028] Working principle:

[0029] In use, the flange is placed between two fixed plates 203. Then, by rotating the handle 204 and the double-acting screw 201, the displacement plate 202 is moved laterally, thereby supporting and fixing the flange through the symmetrically arranged fixed plates 203. At this time, the tilt angle of the frame 1 is detected by the level 5, and the data detected by the level 5 controls the operation of the drive motor 401 and the required electric push rod 408. When the electric push rod 408 works and extends, the moving gear 406 slides along the rotating shaft 407 and meshes with the fixed gear 405. At the same time, the output end of the drive motor 401 drives the worm gear 402 to rotate. Since the worm gear 403 and the worm gear 402 rotate, the worm gear 403 rotates with the worm gear 402. The worm gear 402 engages, causing the worm wheel 403, support column 404, and fixed gear 405 to rotate together. Through the meshing action of the moving gear 406 and the fixed gear 405, the moving gear 406 and the rotating shaft 407 rotate, and under the action of the bevel gear set 409, the threaded column 410 rotates. Since the threaded column 410 is threadedly connected to the support leg 411, the support leg 411 moves linearly along the threaded column 410, thereby restoring the present invention to a horizontal state, so as to better meet the requirements of high precision and high efficiency installation.
