Description

Technical Field

[0001] This utility model relates to the field of steel component hoisting clamps, specifically a steel component hoisting clamp. Background Technology

[0002] Steel components are structural parts with specific shapes and load-bearing functions, made from steel through processing techniques such as cutting, welding, bolting, and bending. Common types include steel beams, steel columns, steel trusses, and steel supports, and they are one of the core components in modern engineering construction.

[0003] Steel components are commonly used in construction, bridges, and machinery manufacturing to provide support, connection, or load-bearing functions. When steel components need to be handled or installed, lifting clamps are required to work with cranes to achieve efficient and safe lifting and transfer, reducing the risks of manual handling and solving the problems of slippage and low efficiency of traditional rope binding. They are indispensable in scenarios such as factory processing and transfer, and construction site installation.

[0004] Existing clamps for lifting steel components mostly use simple jaws, resulting in poor stability during lifting. Therefore, a new type of steel component lifting clamp is proposed to address this problem. Utility Model Content

[0007] Preferably, a fixing plate is fixedly connected to the side wall of the top plate; the fixing plate is located in the middle of the support plate; a bolt is threaded to the top of the fixing plate; by the fixing plate being close to the top of the component along with the top plate, and with the adjustable downward pressure of the bolt, the pressing position can be further increased at a distance from the pressing point of the top plate, so that when the support plate clamps a long steel component, the fixing plate can stabilize the steel component and reduce the up-and-down swaying of the steel component.

[0008] Preferably, an oil inlet is fixedly connected to the top of the clamping rod; the oil inlet is located above the bidirectional screw; a cover plate is fixedly connected to the top of the oil inlet; through the opening of the oil inlet, lubricating oil can be guided to the surface of the bidirectional screw, lubricating the threaded parts of the bidirectional screw and the clamping rod, which can reduce the wear rate, extend the service life of the bidirectional screw and the clamping rod, and also increase the smoothness of the clamping rod movement.

[0009] Preferably, multiple sets of fixed seats are fixed to the side wall of the support plate; the fixed seats are arranged around the support plate; a rotating seat is dampedly connected to the middle of the fixed seat; a searchlight is fixedly connected to the bottom of the rotating seat; by arranging multiple sets of searchlights around the support plate, the clamps and steel components can be illuminated from different directions, and the hoisting status can be clearly understood.

[0011] Preferably, a shielding cloth is fixedly connected to the middle of the support plate; the shielding cloth is connected to the side wall of the clamping rod; the shielding cloth can isolate the bidirectional screw from the outside, prevent contaminants from contacting the surface of the bidirectional screw, ensure that the clamping rod and the bidirectional screw are always clean, and reduce the clamping rod movement jamming caused by impurities.

[0012] The advantages of this utility model are: 1. The steel component hoisting clamp of this utility model forms a lower support and two-sided limit by an L-shaped clamping rod, which, together with the upper pressing of the top plate, forms a multi-faceted constraint, locking the position of the steel component from multiple directions.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Specific implementation examples are given below.

[0019] like Figures 1 to 5As shown in the embodiment of this utility model, a steel component hoisting clamp includes a support plate 1; multiple sets of docking seats 11 are fixedly connected to the top of the support plate 1; the docking seats 11 are arranged around the top of the support plate 1; a drive motor 12 is fixedly connected to the side wall of the support plate 1; a bidirectional screw 13 is fixedly connected to the output end of the drive motor 12; the bidirectional screw 13 is arranged in the middle of the support plate 1 and rotatably connected to the support plate 1; a pair of clamping rods 14 are threadedly connected to the middle of the bidirectional screw 13; the clamping rods 14 are slidably connected in the middle of the support plate 1; a hydraulic rod 15 is fixedly connected to the top of the support plate 1; a top plate 16 is fixedly connected to the output end of the hydraulic rod 15; during operation, the hoisting frame is connected to the support plate 1 through the docking seats 11. After the support plate 1 is installed, it can be moved to the position where it needs to be hoisted. Then, the drive motor 12 is driven to rotate the bidirectional screw 13. The rotation of the bidirectional screw 13 will drive the pair of clamping rods 14 to move, so that the pair of clamping rods 14 move. The clamping rod 14 moves towards the center to clamp the steel component in the middle of the clamping rod 14. After the clamping rod 14 clamps the steel component, the steel component is clamped at the center position of the support plate 1. Then, a pair of hydraulic rods 15 on the top of the support plate 1 are activated. The hydraulic rods 15 can drive the top plate 16 to descend and approach the top of the steel component, pressing down on the steel component. The L-shaped setting of the clamping rod 14 makes the steel component form a lower support, lateral limit and upper pressure during hoisting, forming multi-directional limit on the steel component. After the steel component is hoisted to the designated position, the drive motor 12 drives the bidirectional screw 13 to rotate in the opposite direction. The hydraulic rod 15 drives the top plate 16 to retract and unload the steel component. The lower support and lateral limit formed by the L-shaped clamping rod 14, together with the upper pressure of the top plate 16, form multi-faceted constraints, locking the position of the steel component from multiple directions, so that the steel component can be stably fixed in the center of the support plate 1, reducing the safety hazards such as slippage or falling of the steel component during clamping, and further improving the hoisting stability of the support plate 1.

[0020] like Figures 2 to 3 As shown, a fixing plate 2 is fixedly connected to the side wall of the top plate 16; the fixing plate 2 is located in the middle of the support plate 1; a bolt 21 is threadedly connected to the top of the fixing plate 2; during operation, when the top plate 16 presses down from the top of the steel component and applies a holding force, the fixing plate 2 on the side of the top plate 16 will also move with the top plate 16 and approach the top of the steel component. Then, the bolt 21 is rotated, and the bottom end of the bolt 21 can contact the steel component, so that when the steel component is long, the fixing plate 2 can extend the fixing position of the steel component; by the fixing plate 2 approaching the top of the component with the top plate 16, and in conjunction with the adjustable pressing of the bolt 21, the holding position can be further increased at a distance from the pressing point of the top plate 16, so that when the support plate 1 clamps a long steel component, the fixing plate 2 can stabilize the steel component and reduce the up-and-down swaying of the steel component.

[0021] like Figure 4As shown, an oil inlet 3 is fixedly connected to the top of the clamping rod 14; the oil inlet 3 is located above the bidirectional screw 13; a cover plate 31 is fixedly connected to the top of the oil inlet 3; during operation, the wear of the bidirectional screw 13 and the clamping rod 14 will increase after long-term operation. At this time, the cover plate 31 on the top of the oil inlet 3 can be removed, and then lubricating oil can be added into the oil inlet 3. The lubricating oil can flow into the surface of the bidirectional screw 13 through the opening of the oil inlet 3, and lubricate when the clamping rod 14 and the bidirectional screw 13 are threadedly engaged; the lubricating oil can be guided to the surface of the bidirectional screw 13 through the opening of the oil inlet 3, lubricating the threaded engagement part of the bidirectional screw 13 and the clamping rod 14, which can reduce the wear rate, extend the service life of the bidirectional screw 13 and the clamping rod 14, and also increase the smoothness of the movement of the clamping rod 14.

[0022] like Figure 5 As shown, multiple sets of fixed seats 4 are fixed to the side wall of the support plate 1; the fixed seats 4 are arranged around the support plate 1; a rotating seat 41 is dampedly connected to the middle of the fixed seat 4; a searchlight 42 is fixedly connected to the bottom of the rotating seat 41; during operation, when the support plate 1 is under construction at night, the multiple sets of searchlights 42 on the side of the support plate 1 can be activated, and the searchlights 42 can illuminate the area around the support plate 1. The rotating seat 41 can also be rotated in the middle of the fixed seat 4 to adjust the illumination angle of the searchlights 42; with multiple sets of searchlights 42 arranged around the support plate 1, the clamps and steel components can be illuminated from different directions, and the hoisting status can be clearly understood. The rotating seat 41 is dampedly connected to the fixed seat 4, and the illumination angle of the searchlights 42 can be adjusted by rotating it, so that the light is aimed at key operating points, improving the accuracy of night construction.

[0023] like Figure 1 and Figure 3 As shown, multiple sets of friction strips 5 are fixedly connected to the bottom end of the clamping rod 14; multiple sets of friction strips 5 are fixedly connected to the bottom end of the top plate 16; the friction strips 5 are arranged in an array at the bottom ends of the clamping rod 14 and the top plate 16; during operation, when the clamping rod 14 and the top plate 16 cooperate to fix and clamp the steel component, the friction strips 5 can contact the surface of the steel component, increasing the friction force between the clamping rod 14 and the top plate 16 on the steel component; by arranging multiple sets of friction strips 5 in an array at the bottom ends of the clamping rod 14 and the top plate 16, the contact points and friction force with the surface of the steel component can be increased, reducing the displacement or slippage of the steel component during hoisting.

[0024] like Figure 1As shown, a shielding cloth 6 is fixedly connected to the middle of the support plate 1; the shielding cloth 6 is connected to the side wall of the clamping rod 14; during operation, the shielding cloth 6 at the top of the support plate 1 can shield contaminants from contacting the surface of the bidirectional screw 13, thus isolating the contaminants. When the clamping rod 14 slides, the shielding cloth 6 can also be stretched and deformed along with the sliding of the clamping rod 14; the shielding cloth 6 can isolate the bidirectional screw 13 from the outside, prevent contaminants from contacting the surface of the bidirectional screw 13, ensure that the clamping rod 14 and the bidirectional screw 13 are always clean, and reduce the jamming of the clamping rod 14 caused by impurities.

[0025] Working principle: The hanger is connected to the support plate 1 via the docking seat 11. After the support plate 1 is installed, it can be moved to the position where it needs to be hoisted. Then, the drive motor 12 is driven to rotate the double-headed screw 13. The rotation of the double-headed screw 13 will drive a pair of clamping rods 14 to move towards the center, clamping the steel component in the middle of the clamping rods 14. After the clamping rods 14 clamp the steel component, the steel component is clamped at the center of the support plate 1. Then, the pair of hydraulic rods 15 on the top of the support plate 1 are activated. Hydraulic rod 15 can drive the top plate 16 to descend closer to the top of the steel component, pressing down on the steel component. The L-shaped arrangement of the clamping rod 14 creates a lower support, lateral limiters, and upper pressure on the steel component during hoisting, providing multi-directional limitation. After the steel component is hoisted to the designated position, the drive motor 12 drives the bidirectional screw 13 to rotate in the opposite direction. The hydraulic rod 15 then drives the top plate 16 to retract, allowing the steel component to be unloaded. When the top plate 16 presses down from the top of the steel component, applying pressure, the fixing plate 2 on the side of the top plate 16 will also move along with the top plate 16, approaching the top of the steel component. Then, rotate bolt 21 so that the bottom end of bolt 21 can contact the steel component. This allows the fixing plate 2 to extend the fixing position of the steel component when the steel component is long. After long-term operation, the wear of the double-acting screw 13 and the clamping rod 14 will increase. At this time, the cover plate 31 on the top of the oil inlet 3 can be removed, and lubricating oil can be added into the oil inlet 3. The lubricating oil can flow into the surface of the double-acting screw 13 through the opening of the oil inlet 3, and lubrication can be provided when the clamping rod 14 and the double-acting screw 13 are threaded together. When the support plate 1 is used for nighttime construction, the side of the support plate 1 can be activated. The multiple sets of searchlights 42 can illuminate the area around the support plate 1. The angle of the searchlights 42 can also be adjusted by rotating the rotating base 41 in the middle of the fixed base 4. When the clamping rod 14 and the top plate 16 are used to fix and clamp the steel component, the friction strip 5 can contact the surface of the steel component, increasing the friction between the clamping rod 14 and the top plate 16 on the steel component. The shielding cloth 6 on the top of the support plate 1 can block pollutants from contacting the surface of the bidirectional screw 13, thus isolating the pollutants. When the clamping rod 14 slides, the shielding cloth 6 can also be stretched and deformed along with the sliding of the clamping rod 14.
