Description

Technical Field

[0001] This utility model relates to the field of lifting tool technology, specifically a profile lifting tool. Background Technology

[0002] Utility model patent CN218950824U discloses a profile processing lifting tool, including a connecting block. An opening is formed on the right surface of the connecting block, penetrating the block. A battery is fixedly connected to the bottom surface inside the opening. An electric push rod is fixedly connected to the bottom of the connecting block, with its top penetrating the block and electrically connected to the battery. Two rectangular plates are fixedly connected to the bottom of the connecting block, and a movable frame is fixedly connected to the bottom of the two rectangular plates. A movable strip is fixedly connected to the inner surface of the movable frame, and a groove is formed on the upper surface of the movable strip. A sliding device, including a fixed block, is provided at the bottom of the electric push rod. This design allows for a closer fit to the inner wall of the large aluminum tube being clamped, increasing the contact area and making clamping more stable and less prone to disengagement. It also reduces swaying during clamping of large aluminum tubes, increasing the stability and safety of the lifting tool.

[0003] However, this device is not easy to adjust during use, making it difficult to clamp and lift profiles of different widths. Its applicability is low. Furthermore, the device has low stability in clamping profiles, posing safety hazards during lifting. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a profile lifting device that solves the problems of the device being inconvenient to adjust during use, making it difficult to clamp and lift profiles of different widths, having low applicability, and having low clamping stability for profiles, which may cause safety hazards during lifting.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a profile lifting device, including a crossbar, a lifting ring at the upper end of the crossbar, a clamping seat slidably connected to the lower end of the crossbar, a lifting block fixedly connected to the upper end of the clamping seat, a bidirectional screw threadedly connected inside the lifting block, a connecting rod fixedly connected to the surface of the crossbar, the connecting rod and the bidirectional screw being rotatably connected, and a fixing mechanism being provided on the connecting rod.

[0006] Preferably, a dovetail block is fixedly connected to the upper end of the clamp, and the dovetail block is slidably connected to the crossbar. The dovetail block guides the movement of the clamp.

[0007] Preferably, a limiting plate is fixedly connected inside the connecting rod, and the limiting plate is rotatably connected to the bidirectional screw. The limiting plate prevents the bidirectional screw from moving out of control.

[0008] Preferably, the fixing mechanism includes a lifting rod, with a lifting rod slidably connected inside the connecting rod. A pressure plate is fixedly connected to the lower end of the lifting rod, and the pressure plate contacts the connecting rod. A connecting plate is fixedly connected to the upper end of the lifting rod, and a screw is movably connected inside the connecting plate. The screw and the connecting rod are connected by a bearing, and a top plate is threadedly connected to the outer side of the screw. A compression spring is provided on the outer side of the screw. By rotating the screw and the top plate to perform threaded movement, the compression spring elastically presses down on the connecting plate, causing the connecting plate to move through the lifting rod, thus pressing the profile between the two clamps. This results in higher stability during profile hoisting and avoids potential safety hazards.

[0009] Preferably, one end of the compression spring is fixedly connected to the top plate, and the other end of the compression spring is fixedly connected to the connecting plate. By setting the compression spring, the connecting plate can be elastically pressed down.

[0010] Preferably, a sliding rod is fixedly connected to the upper end of the connecting plate, and the sliding rod is slidably connected to the pressure plate. The sliding rod guides the movement of the pressure plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses a rotating bidirectional screw and a lifting block to make a threaded movement, which allows the lifting block to drive the clamp to slide at the lower end of the crossbar. This allows for clamping and limiting of profiles of different widths, thus enabling the device to lift profiles of different models.

[0013] 2. This utility model uses the rotating screw and top plate to make a threaded movement, which causes the compression spring to elastically press down the connecting plate. This causes the connecting plate to move the pressure plate through the lifting rod, pressing the profile between the two clamps. This makes the profile more stable during hoisting and avoids safety hazards. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 A profile lifting device includes a crossbar 1, a lifting ring 2 at the upper end of the crossbar 1, a clamping seat 3 slidably connected to the lower end of the crossbar 1, a dovetail block 4 fixedly connected to the upper end of the clamping seat 3, the dovetail block 4 and the crossbar 1 being slidably connected, the dovetail block 4 guiding the movement of the clamping seat 3, a lifting block 5 fixedly connected to the upper end of the clamping seat 3, a double-ended screw 6 threadedly connected inside the lifting block 5, a connecting rod 7 fixedly connected to the surface of the crossbar 1, the connecting rod 7 and the double-ended screw 6 being rotatably connected, a limiting plate 8 fixedly connected inside the connecting rod 7, the limiting plate 8 and the double-ended screw 6 being rotatably connected, the limiting plate 8 preventing the double-ended screw 6 from moving, and a fixing mechanism 9 on the connecting rod 7.

[0021] Please see Figure 1 , Figure 3 The fixing mechanism 9 includes a lifting rod 91, which is slidably connected to the connecting rod 7. A pressure plate 92 is fixedly connected to the lower end of the lifting rod 91, and the pressure plate 92 contacts the connecting rod 7. A connecting plate 93 is fixedly connected to the upper end of the lifting rod 91. A screw 94 is movably connected to the inside of the connecting plate 93. The screw 94 and the connecting rod 7 are connected by a bearing. A top plate 95 is threadedly connected to the outside of the screw 94. A compression spring 96 is provided on the outside of the screw 94. One end of the compression spring 96 is fixedly connected to the top plate 95, and the other end of the compression spring 96 is fixedly connected to the connecting plate 93. Next, by setting a compression spring 96, the connecting plate 93 is elastically pressed down. The upper end of the connecting plate 93 is fixedly connected to a slide rod 97, which is slidably connected to the top plate 95. By setting the slide rod 97, the movement of the top plate 95 is guided. By rotating the screw 94 and the top plate 95 to make threaded movement, the compression spring 96 elastically presses down the connecting plate 93, which in turn causes the connecting plate 93 to drive the pressure plate 92 to move through the lifting rod 91, pressing the profile between the two clamps 3, making the profile more stable during hoisting and avoiding safety hazards.

[0022] The specific implementation process of this utility model is as follows: In use, the rigging and lifting ring 2 are fixed, and the moving device is used to position the two clamps 3 on both sides of the profile. The double-acting screw 6 is manually rotated, and the double-acting screw 6 rotates and the lifting block 5 makes a threaded movement, which allows the lifting block 5 to drive the clamps 3 to slide at the lower end of the crossbar 1. This can clamp and limit profiles of different widths, and thus the device can lift profiles of different models. Then, the screw 94 is rotated, and the screw 94 rotates and the top plate 95 makes a threaded movement, which causes the top plate 95 to move down. The top plate 95 drives the compression spring 96 to move down, and the compression spring 96 elastically presses down the connecting plate 93, which in turn causes the connecting plate 93 to drive the lifting rod 91 to move down. The lifting rod 91 drives the pressure plate 92 to move, so that the pressure plate 92 contacts the profile and presses the profile between the two clamps 3, which makes the profile more stable during the lifting process and avoids safety hazards.
