Description

Technical Field

[0001] This utility model relates to the field of steel plate lifting tools, specifically a steel plate lifting tool that can adapt to different widths. Background Technology

[0002] Steel plate lifting devices are specialized lifting equipment used for the safe and efficient lifting of heavy objects such as steel plates. They typically use clamps, vacuum suction cups, or electromagnetic devices to firmly grip the steel plates. The main types include clamp-type lifting devices, which use leverage to clamp the edges of the steel plates, and magnetic lifting devices, which use permanent magnets or electromagnets to generate attraction force. Therefore, these tools can effectively prevent the steel plates from slipping or deforming during lifting. In addition, they are widely used in ports, steel mills, workshops, and other places. When using them, safety regulations must be strictly followed to ensure that the load is matched and the lifting point is correct.

[0003] According to a search, Chinese patent document (publication number CN222907292U) discloses a steel plate lifting device, including a support bar, lifting assemblies, and a clamping device. The upper parts of several lifting assemblies are connected to the support bar, and the lower parts of the lifting assemblies pass through the clamping device. A steel plate is positioned between the lifting assemblies and the clamping device. Each lifting assembly includes a first shackle, a first connecting rope, a second connecting rope, a first steel plate clamp, and a second steel plate clamp. The first shackle is mounted on the support bar, and two first connecting ropes are symmetrically mounted on the first shackle. The second connecting rope passes through the first steel plate clamp, the clamping device, and the second steel plate clamp. The ends of the second connecting ropes are connected to the two first connecting ropes via two second shackles. This application improves the safety of the lifting process by positioning the middle position of the second connecting rope at the clamping bar fixing assembly. The clamping device applies a downward force to the steel plate through a clamping tube.

[0004] The aforementioned device uses a three-sided rectangular steel plate clamp, but lacks a locking mechanism to prevent the steel plate from sliding back. Therefore, when the steel plate is slightly tilted, the equipment vibrates, or it is subjected to external interference, there is a risk that the steel plate may slip backward. This means that the steel plate cannot be reliably locked within the clamp frame, which not only threatens the safety of personnel and equipment below, but also may cause damage to the steel plate itself. In view of this, we provide a steel plate lifting device that can adapt to different widths. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a steel plate lifting tool that can adapt to different widths.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel plate lifting device capable of adapting to different widths, comprising a lifting frame, wherein multiple hooks are fixedly connected to the top surface of the lifting frame, multiple sliding rods are fixedly connected to both sides of the outer wall of the lifting frame, and multiple sliding brackets are provided on the outer walls at both ends of the sliding rods; a bidirectional threaded rod is rotatably connected to the center of the inner wall of the lifting frame, and multiple knobs are fixedly connected to both ends of the bidirectional threaded rod; and multiple sliding grooves are provided on both sides of the inner cavity of the lifting frame.

[0007] The bottom outer wall of the sliding frame is fixedly connected with multiple clamps, and multiple limiting components are provided inside the clamps. Multiple one-way teeth are added to the outer wall of the clamps.

[0008] As described above, the outer wall of one end of the sliding rod penetrates through one side of the interior of the sliding frame, and the interior of the sliding frame is slidably connected to the outer wall of one end of the sliding rod.

[0009] As described above, the plurality of sliding grooves are respectively located on both sides of the outer wall of the sliding frame, one side of the outer wall of the sliding frame is in close contact with the inner wall of the sliding groove, and the other side of the outer wall of the sliding frame is slidably connected to the inner wall of the sliding groove.

[0010] As mentioned above, the multiple sliding frames are located at both ends of the bidirectional threaded rod, and the two ends of the bidirectional threaded rod are connected to the internal central thread of the sliding frame.

[0011] As described above, the clamp has a three-sided rectangular structure when viewed from the side, and a bevel is provided at the bottom of one side of the clamp.

[0012] As described above, the limiting member is located at the center inside the fixture, and the top outer wall of the limiting member is rotatably connected to the center inside the fixture.

[0013] As described above, the overall structure of the limiting component is semi-circular, and one side of the arc-shaped surface of the limiting component faces the opening direction of the clamp. Multiple one-way teeth are provided on the outer wall of the arc-shaped surface of the limiting component, and a groove is provided in the center of the inner cavity of the limiting component.

[0014] Compared with existing technologies, this steel plate lifting tool, which can adapt to different widths, has the following advantages:

[0015] I. This utility model, by setting the limiting component at the center inside the clamp, when the clamp covers the edge of the steel plate, the steel plate will contact and push the arc-shaped surface of the limiting component to rotate upward into the clamp. The multiple one-way teeth set on the arc-shaped surface will press against the surface of the steel plate. When the steel plate tends to retreat, the tooth structure of the one-way teeth will immediately bite the surface of the steel plate. Thus, under the combined action of the limiting component and the one-way teeth, it can effectively prevent the steel plate from sliding backward during the hoisting process due to slight tilting, equipment vibration or external interference, so that the steel plate is firmly locked inside the clamp, minimizing the risk of slippage during the hoisting process and the resulting safety hazards.

[0016] II. By rotating the knob, this utility model can directly drive the bidirectional threaded rod to rotate, pushing the sliding frame to move along the linear motion of the sliding rod. The sliding frames connected to its two ends will move towards each other synchronously and symmetrically. Adjusting the distance between the clamps at the bottom of the sliding frame allows the edges of steel plates of different widths to enter the clamps.

[0017] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0025] 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.

[0026] like Figure 1-6As shown, this utility model provides a technical solution for a steel plate lifting device that can adapt to different widths: a steel plate lifting device that can adapt to different widths includes a lifting frame 1, a plurality of hooks 101 fixedly connected to the top surface of the lifting frame 1, a plurality of sliding rods 2 fixedly connected to both sides of the outer wall of the lifting frame 1, and a plurality of sliding frames 201 provided on the outer walls at both ends of the sliding rods 2, a bidirectional threaded rod 202 rotatably connected to the center of the inside of the lifting frame 1, and a plurality of knobs 203 fixedly connected to both ends of the bidirectional threaded rod 202, and a plurality of sliding grooves 204 opened on both sides of the inner cavity of the lifting frame 1;

[0027] Multiple clamps 3 are fixedly connected to the bottom outer wall of the sliding frame 201, and multiple limiting components 301 are provided inside the clamps 3. Multiple one-way teeth 302 are added to the outer wall of the clamps 3.

[0028] By setting the limiting member 301 inside the center of the clamp 3, when the clamp 3 covers the edge of the steel plate, the steel plate will contact and push the arc-shaped surface of the limiting member 301 to rotate upward into the clamp 3. The multiple one-way teeth 302 set on the arc-shaped surface will press against the surface of the steel plate. When the steel plate has a tendency to retreat, the tooth structure of the one-way teeth 302 will immediately bite the surface of the steel plate, thereby constraining and limiting the retreat behavior of the steel plate.

[0029] like Figure 2 As shown, one end of the outer wall of the sliding rod 2 penetrates through one side of the interior of the sliding frame 201, and the interior side of the sliding frame 201 is slidably connected to the outer wall of one end of the sliding rod 2.

[0030] The sliding rod 2 passes through one side of the interior of the sliding frame 201 and is slidably connected to it, so that the sliding frame 201 can move smoothly in a straight line along the sliding rod 2, providing guidance for the sliding frame 201.

[0031] like Figures 3-4 As shown, multiple sliding grooves 204 are located on both sides of the outer wall of the sliding frame 201. One side of the outer wall of the sliding frame 201 is in close contact with the inner wall of the sliding groove 204, and the other side of the outer wall of the sliding frame 201 is slidably connected to the inner wall of the sliding groove 204.

[0032] The outer wall of the sliding frame 201 is tightly fitted with the inner wall of the sliding groove 204, and the sliding rod 2 further constrains the movement trajectory of the sliding frame 201 to ensure its stability during movement.

[0033] like Figure 3 As shown, multiple sliding frames 201 are located at both ends of the bidirectional threaded rod 202, and both ends of the bidirectional threaded rod 202 are connected to the internal center thread of the sliding frame 201.

[0034] Multiple sliding brackets 201 are located at both ends of the bidirectional threaded rod 202 and are threadedly connected to it. When the knob 203 is rotated, the sliding brackets 201 at both ends of the bidirectional threaded rod 202 can move synchronously and symmetrically.

[0035] like Figure 5 As shown, the fixture 3 has a three-sided rectangular structure when viewed from the side, and a bevel is provided on the bottom of one side of the fixture 3.

[0036] The clamp 3 has a three-sided rectangular structure and an angled opening on one side of its bottom. When lifting steel plates, the angled opening can more easily guide the edge of the steel plate into the interior of the clamp 3, avoiding the steel plate from getting stuck with the edge of the clamp 3.

[0037] like Figure 6 As shown, the limiting member 301 is located at the center inside the fixture 3, and the top outer wall of the limiting member 301 is rotatably connected to the center inside the fixture 3.

[0038] The limiting member 301 is located inside the center of the clamp 3, and its top is rotatably connected to the clamp 3, so that the limiting member 301 can swing flexibly inside the clamp 3 under the action of gravity, which can better adapt to the surface of steel plates of different thicknesses, and adapt to steel plates of different thicknesses during the clamping process.

[0039] like Figure 6 As shown, the overall structure of the limiting member 301 is semi-circular, and one side of the arc surface of the limiting member 301 faces the opening direction of the clamp 3. Multiple one-way teeth 302 are provided on the outer wall of the arc surface of the limiting member 301, and a groove 303 is provided in the center of the inner cavity of the limiting member 301.

[0040] The limiting member 301 is semi-circular, with its arc-shaped surface facing the opening of the clamp 3 and equipped with one-way teeth 302. A groove 303 is opened in the center of its inner cavity, so that when the steel plate is inserted into the clamp 3, the arc-shaped surface of the limiting member 301 and the one-way teeth 302 can effectively bite the surface of the steel plate. At the same time, the groove 303 makes it easy for the operator to access the restriction on the steel plate and remove the steel plate from the clamp 3. The one-way teeth 302 and the semi-circular limiting member 301 can effectively prevent the clamped steel plate from accidentally slipping back.

[0041] Working principle: The sliding rod 2 passes through one side of the sliding frame 201 and is slidably connected to it, allowing the sliding frame 201 to move smoothly in a straight line along the sliding rod 2, providing guidance for the sliding frame 201. The outer wall of the sliding frame 201 is tightly fitted to the inner wall of the sliding groove 204, further constraining the movement trajectory of the sliding frame 201 in conjunction with the sliding rod 2, ensuring its stability during movement. Multiple sliding frames 201 are located at both ends of the bidirectional threaded rod 202 and are threadedly connected to it. When the knob 203 is rotated, the sliding frames 201 at both ends of the bidirectional threaded rod 202 can move synchronously and symmetrically. The clamp 3 has a three-sided rectangular structure, and through the bevel on one side of its bottom, when lifting steel plates, the bevel can more easily guide the edge of the steel plate into the interior of the clamp 3, avoiding contact between the steel plate and the edge of the clamp 3. When jamming occurs, the limiting member 301 is located at the center inside the clamp 3, and its top is rotatably connected to the clamp 3. This allows the limiting member 301 to swing flexibly inside the clamp 3 under the action of gravity, which can better adapt to the surface of steel plates of different thicknesses. During the clamping process, it can adapt to steel plates of different thicknesses on its own. The limiting member 301 is semi-circular, with its arc-shaped surface facing the opening of the clamp 3 and equipped with one-way teeth 302. Its inner cavity has a groove 303, which allows the arc-shaped surface of the limiting member 301 and the one-way teeth 302 to effectively bite the surface of the steel plate when the steel plate is inserted into the clamp 3. At the same time, the groove 303 makes it easy for the operator to access the restriction on the steel plate and remove the steel plate from the clamp 3. The one-way teeth 302 and the semi-circular limiting member 301 can effectively prevent the clamped steel plate from accidentally slipping back.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
