Description

Technical Field

[0001] This utility model is a steel plate clamp, belonging to the field of steel plate clamping devices. Background Technology

[0002] When steel plates are traditionally hoisted using wire ropes or chains, workers need to manually thread the ropes and hook them at close range. During the hoisting process, the steel plates may sway, slip, or even fall, which can easily cause serious workplace accidents such as crushing or squeezing injuries.

[0003] However, during the transportation of steel plates, the clamping ends of the steel plate clamping equipment will wear out due to prolonged contact with the steel plates. However, the wear of the clamping ends does not necessarily require the replacement of the entire equipment, as the replacement cost is high and it is not conducive to the use of the equipment.

[0004] Therefore, there is a need for an industrial device specifically designed for the safe and stable gripping, handling, and moving of steel plates. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a steel plate clamp.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] A steel plate clamp includes a clamp body with a rotating shaft rotatably connected to it. A rotating component is fixed in the middle of the rotating shaft. A clamping tongue and a lifting component are respectively provided on both sides of the outer surface of the rotating component. An installation hole is provided in the bottom of the clamp body. An inlet and outlet and a sliding groove are respectively provided on both sides of the top of the installation hole. A pad is installed in the installation hole and is slidably connected in the sliding groove. A gravity locking mechanism is provided inside the clamp body to cooperate with the rotating component and the pad.

[0008] Furthermore, the pad includes a sliding seat and a pressing plate, with a sliding channel formed between the sliding seat and the pressing plate. The sliding seat is slidably installed in the mounting hole. The bottom of the clamp body is connected and fixed to the sliding seat by a long screw. The pressing plate is located inside the clamp body and is adapted to the clamp tongue.

[0009] Furthermore, the inlet and outlet are adapted to the sliding seat, and the sliding channel is adapted to the sliding groove.

[0010] Furthermore, the gravity locking mechanism includes an arc-shaped pressing block fixed to one side of the rotating component and a slide rail fixed inside the clamp body. A vertical slider is vertically slidably connected inside the slide rail. A horizontal slider one and a horizontal slider two are horizontally slidably connected in two horizontal openings on the side of the slide rail, respectively. The horizontal slider one and the horizontal slider two are pressed together with the inclined end of the vertical slider. The end of the horizontal slider two extends horizontally into the mounting hole and is pressed together with the outer surface of the sliding seat.

[0011] Furthermore, the clamp body includes a first body and a second body, which are connected and fixed together by locking bolts.

[0012] Furthermore, the slide rail is fixed on the first body, and the second body has a plurality of ball bearings rotatably connected to the side of the first body, the positions of the plurality of ball bearings being adapted to the slide rail.

[0013] Furthermore, the rotating shaft, the rotating component, the clamping tongue, and the lifting component are all integrated into a single structure.

[0014] The beneficial effects of this utility model are:

[0015] The design of the pad allows for the installation of a replaceable pad between the steel plate to be lifted and the jaws, thereby reducing wear on the steel plate clamp and enabling the equipment to be reused by replacing parts when the jaws and pads wear out, thus extending the service life of the equipment.

[0016] Through the design of the gravity locking mechanism, during the steel plate hoisting process, the rotation of the rotating component will drive the arc-shaped extrusion block to rotate. The arc-shaped extrusion block will extrude the inclined surface of the first horizontal slider, thereby pushing the first horizontal slider to move laterally within the slide rail. The first horizontal slider will extrude the top inclined surface of the vertical slider through the inclined surface, and the bottom inclined surface of the vertical slider will extrude the inclined surface of the second horizontal slider, causing the second horizontal slider to move laterally. During the lateral movement of the second horizontal slider, the end will extrude the sliding seat laterally. Through lateral extrusion, the sliding seat will be forced not to move to the inlet and outlet, ensuring that the sliding seat is stably installed in the mounting hole and improving the connection between the pad and the insert.

[0024] 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.

[0025] Please see Figures 1-5This utility model provides a steel plate clamping device, including a clamp body 1. A rotating shaft 15 is rotatably connected to the clamp body 1. A rotating component 16 is fixed in the middle of the rotating shaft 15. Clamping tongues 17 and lifting components 18 are respectively provided on both sides of the outer surface of the rotating component 16. The rotating shaft 15, rotating component 16, clamping tongues 17, and lifting components 18 are integrated into a single structure. A mounting hole 5 is provided at the bottom of the clamp body 1. An inlet / outlet 6 and a sliding groove 7 are respectively provided on both sides of the top of the mounting hole 5. A pad 10 is installed in the mounting hole 5 and slidably connected in the sliding groove 7. The body 1 is equipped with a gravity locking mechanism that cooperates with the rotating part 16 and the pad 10. During the process of lifting the steel plate with the steel plate clamp, a set of steel plate clamps are respectively clamped on both sides of the steel plate. Then, the hook of the lifting equipment is hung on the lifting part 18 on the steel plate clamp. The lifting equipment pulls the hook to drive the steel plate clamp to rise. The lifting part 18 is pulled and will drive the jaw 17 to rotate around the pivot 15. The jaw 17 will squeeze the steel plate placed on the pad 10. The greater the weight of the steel plate, the greater the downward force of the jaw 17, and the tighter the steel plate clamp holds the steel plate, thus maintaining a gravity self-locking effect.

[0026] See Figure 1 , Figure 3 The pad 10 includes a sliding seat 8 and a pressing plate 9, forming a sliding channel between the sliding seat 8 and the pressing plate 9. The sliding seat 8 is slidably installed in the mounting hole 5. The bottom of the clamp body 1 is connected and fixed to the sliding seat 8 by a long screw 20. The pressing plate 9 is located inside the clamp body 1 and is adapted to the clamp tongue 17. The inlet and outlet 6 are adapted to the sliding seat 8, and the sliding channel is adapted to the slide groove 7. Through the design of the pad 10, a replaceable pad 10 is provided between the steel plate to be lifted and the clamp tongue 17, thereby reducing the wear of the steel plate clamp and enabling the reuse of the equipment by replacing parts when the clamp tongue 17 and the pad 10 are worn, thus improving the service life of the equipment.

[0027] See Figures 3-5The gravity locking mechanism includes an arc-shaped pressing block 19 fixed to one side of the rotating component 16 and a slide rail 11 fixed inside the clamp body 1. A vertical slider 12 is vertically slidably connected inside the slide rail 11. A horizontal slider 13 and a horizontal slider 2 14 are horizontally slidably connected to two horizontal openings on the side of the slide rail 11, respectively. Both the horizontal slider 13 and the horizontal slider 2 14 are pressed together with the inclined end of the vertical slider 12. The end of the horizontal slider 2 14 extends horizontally into the mounting hole 5 and is pressed together with the outer surface of the sliding seat 8. Through the design of the gravity locking mechanism, during the steel plate hoisting process, During the rotation of the rotating component 16, the arc-shaped extrusion block 19 will rotate. The arc-shaped extrusion block 19 will extrude the inclined surface of the horizontal slider 13, thereby pushing the horizontal slider 13 to move laterally within the slide rail 11. The horizontal slider 13 will extrude the top inclined surface of the vertical slider 12 through the inclined surface. The bottom inclined surface of the vertical slider 12 will extrude the inclined surface of the horizontal slider 14 through the pressure, causing the horizontal slider 14 to move laterally. During the lateral movement of the horizontal slider 14, the end will laterally extrude the sliding seat 8. Through lateral extrusion, the sliding seat 8 will be forced not to move to the inlet / outlet 6, ensuring that the sliding seat 8 is stably installed in the mounting hole 5, and improving the connection between the pad 10 and the insert 1.

[0028] See Figures 1-2 The clamp body 1 includes a first body 2 and a second body 3, which are connected and fixed by locking bolts 4. The design of the split structure of the insert 1 facilitates the installation of the gravity locking mechanism. At the same time, the setting of several sets of locking bolts 4 and nuts ensures that the strength of the insert 1 is sufficient to meet the hoisting requirements of the steel plate.

[0029] The slide rail 11 is fixed on the main body 2. The main body 3 is connected to a number of ball bearings (not shown in the figure) on the side close to the main body 2. The positions of the ball bearings are adapted to the slide rail 11. Through the design of the ball bearings, the friction between the vertical slider 12, the horizontal slider 13 and the horizontal slider 2 14 and the main body 3 can be reduced, while improving the movement ability of the three.

[0030] During the lifting of steel plates using the steel plate clamps, a set of steel plate clamps is clamped onto both sides of the steel plate. Then, the hook of the lifting equipment is attached to the lifting component 18 on the steel plate clamps. The lifting equipment pulls the hook to raise the steel plate clamps. The lifting component 18, under tension, causes the jaws 17 to rotate around the pivot 15. The jaws 17 then press against the steel plate placed on the pad 10. The greater the weight of the steel plate, the greater the downward pressure of the jaws 17, resulting in a tighter grip on the steel plate, maintaining a gravity-locked effect. During the steel plate lifting process, the rotating component 16 rotates, causing the curved surface... When the extrusion block 19 rotates, the arc-shaped extrusion block 19 will extrude the inclined surface of the horizontal slider 13, thereby pushing the horizontal slider 13 to move laterally within the slide rail 11. The horizontal slider 13 will extrude the top inclined surface of the vertical slider 12 through the inclined surface. The bottom inclined surface of the vertical slider 12 will extrude the inclined surface of the horizontal slider 14 through the pressure, causing the horizontal slider 14 to move laterally. During the lateral movement of the horizontal slider 14, the end will laterally extrude the sliding seat 8. Through lateral extrusion, the sliding seat 8 will be forced not to move to the inlet / outlet 6, ensuring that the sliding seat 8 is stably installed in the mounting hole 5, and improving the connection between the pad 10 and the insert 1.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
