Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structure hoisting technology, and in particular to a hoisting machine for preventing steel structures from falling off. Background Technology
[0002] Steel structures are load-bearing structural systems constructed primarily of steel, widely used in various building projects such as industrial plants, high-rise buildings, bridges, and stadiums. They possess advantages such as high strength, light weight, good toughness, short construction period, and recyclability, effectively withstanding various external forces such as wind loads and seismic forces, thus improving the safety and stability of buildings.
[0003] Existing steel structures are prone to slipping during hoisting operations. Slipping steel structures can cause fatal injuries to on-site construction workers and may also damage nearby equipment or buildings. Slipping steel structures may cause damage or deformation to the materials themselves, which not only increases the cost of repairing or replacing damaged parts, but may also delay the project schedule and increase indirect costs. Once a slipping incident occurs, work must be stopped to assess and handle the consequences of the accident, including but not limited to cleaning up the site, replacing damaged materials, and rescheduling the hoisting plan, all of which will lead to project delays.
[0004] Therefore, it is necessary to design a steel structure anti-fall hoisting machine to solve the above-mentioned technical problems. Utility Model Content
[0005] To overcome the drawbacks of steel structure hoisting, such as easy slippage, potential injury or death, equipment damage, and material deformation, which increases repair costs and delays the construction period, and requires work stoppage for site cleanup and plan adjustments, further leading to construction delays, this utility model provides a steel structure anti-slip hoisting machine.
[0006] The technical solution is as follows: A steel structure anti-fall hoisting machine includes a frame, a control panel, a warning light, an electric slide rail, a slider, a first motor, a winding wheel, a steel wire rope, a fixing plate, fixing blocks, connecting ropes, electromagnets, and clamping components. The control panel is fixedly connected to the lower part of the frame, and a warning light is fixedly connected to the middle part of the frame. The warning light is electrically connected to the control panel. An electric slide rail is fixedly connected to the top of the frame and is electrically connected to the control panel. A slider is slidably connected to the top of the electric slide rail. A first motor is fixedly connected to the top of the slider and is electrically connected to the control panel. A winding wheel is fixedly connected to the output shaft of the first motor, and a steel wire rope is wound on the winding wheel. A fixing plate is fixedly connected to the lower part of the steel wire rope. Fixing blocks are symmetrically fixedly connected to the bottom of the fixing plate. Connecting ropes are fixedly connected to the top of each of the two fixing blocks. Electromagnets are fixedly connected to the bottom of each of the two connecting ropes. Both electromagnets are electrically connected to the control panel. A clamping component is provided at the lower part of the fixing plate.
[0007] Furthermore, the clamping assembly includes a movable frame, a second motor, a screw, a column, clamping blocks, and an anti-slip rubber sleeve. The movable frame is slidably connected to both sides of the fixed plate, and the second motor is fixedly connected to both sides of the top of the fixed plate. Both second motors are electrically connected to the control panel. The output shafts of the two second motors are fixedly connected to screws, and the two screws are threadedly connected to the corresponding movable frames. The columns are fixedly connected to both sides of the two movable frames. Four sets of clamping blocks are rotatably connected to the bottom of the fixed plate, with two clamping blocks in each set. Each clamping block is fixedly fitted with an anti-slip rubber sleeve.
[0008] Furthermore, each clamping block is provided with a sliding groove, and each column slides within the corresponding sliding groove.
[0009] Furthermore, the two clamping blocks in each group are arranged in an alternating symmetrical pattern.
[0010] Furthermore, it also includes sensors, with sensors fixedly connected to both sides of the top of the fixed plate, and both sensors are electrically connected to the control panel.
[0011] Furthermore, it also includes a connecting frame, a sleeve, abutting rods, and springs. Connecting frames are symmetrically fixed to both sides of the fixing plate. A sleeve is fixedly connected to the bottom of each connecting frame. Abutting rod is slidably connected inside each sleeve. A spring is connected between each abutting rod and the corresponding sleeve.
[0012] The beneficial effects of this utility model are as follows: Through the synergistic effect of the fixed plate, electromagnet, clamping block, screw, moving frame, first motor, wire rope and shock-absorbing components, this utility model achieves stable clamping and safe lifting during the steel structure hoisting process. The electromagnet adsorption, combined with the clamping block, effectively prevents the steel structure from slipping. The anti-slip rubber sleeve enhances the clamping friction and improves safety. During the lifting process, the damping structure composed of sleeve, spring and abutment rod buffers and reduces shock on the fixed plate, improving the smoothness of operation. At the same time, the sensor can monitor the tilt angle of the fixed plate in real time, and trigger the warning light to remind personnel to avoid the abnormality, further ensuring the safety of operation.

Detailed Implementation
[0020] Example: A steel structure anti-falling hoist, such as Figures 1-6 As shown, the assembly includes a frame 1, a control panel 2, a warning light 3, an electric slide rail 4, a slider 5, a first motor 6, a winding wheel 7, a steel wire rope 8, a fixing plate 9, a fixing block 17, a connecting rope 18, an electromagnet 19, a moving frame 10, a second motor 11, a screw 12, a column 13, a clamping block 14, and an anti-slip rubber sleeve 15. The control panel 2 is screwed onto the lower front side of the frame 1. The warning light 3 is screwed onto the middle right side of the frame 1 and is electrically connected to the control panel 2. The electric slide rail 4 is screwed onto the top of the frame 1 and is electrically connected to the control panel 2. A slider 5 is slidably connected to the top of the electric slide rail 4. The first motor 6 is screwed onto the top of the slider 5 and is electrically connected to the control panel 2. The output shaft of the first motor 6 extends forward and is welded to a winding wheel 7. A steel wire rope 8 is wound on the winding wheel 7. A fixing plate 9 is welded to the lower end of the steel wire rope 8. The bottom of the fixing plate 9 is symmetrically welded front and back. The system includes two fixed blocks 17, each with a connecting rope 18 welded to its top. Each connecting rope 18 has an electromagnet 19 mounted on its bottom via screws. Both electromagnets 19 are electrically connected to the control panel 2. Movable frames 10 are slidably connected to the left and right sides of the fixed plate 9. Second motors 11 are mounted on the top left and right sides of the fixed plate 9 via screws. Both second motors 11 are electrically connected to the control panel 2. Screws 12 are welded to the upward-extending output axes of both second motors 11. Both screws 12 are threadedly connected to the corresponding movable frames 10. Columns 13 are welded to the front and rear sides of both movable frames 10. Four sets of clamping blocks 14 are rotatably connected to the bottom of the fixed plate 9. Each set of clamping blocks 14 consists of two blocks. Each clamping block 14 has a sliding groove, and each column 13 slides within its corresponding groove. Anti-slip rubber sleeves 15 are fixedly fitted onto each clamping block 14. The two clamping blocks 14 in each set are symmetrically distributed, alternating left and right.
[0021] like Figure 3As shown, it also includes sensors 16. Sensors 16 are installed on the front and rear sides of the top of the mounting plate 9 by screws. Both sensors 16 are electrically connected to the control panel 2.
[0022] like Figure 1 and Figure 6 As shown, it also includes a connecting frame 20, a sleeve 21, abutting rod 23 and a spring 22. The connecting frame 20 is symmetrically installed on both the front and rear sides of the fixing plate 9 by screws. A sleeve 21 is welded to the bottom of each connecting frame 20. Abutting rod 23 is slidably connected inside each sleeve 21. A spring 22 is connected between each abutting rod 23 and the corresponding sleeve 21.
[0023] When the device is needed, first place the fixing plate 9 directly above the steel structure, with the abutment rod 23 in contact with the ground. Then, place the electromagnet 19 on the steel structure. Next, activate the electromagnet 19 via the control panel 2. The electromagnet 19 will generate a strong magnetic force, firmly adhering the steel structure to the fixing plate 9. Then, activate the second motor 11 via the control panel 2. The conveyor shaft of the second motor 11 drives the screw 12 to rotate clockwise, causing the moving frame 10 to move downwards and the column 13 to move along the slide rail. The two clamps... Block 14 rotates towards the steel structure and clamps and fixes the steel structure. After fixing, the second motor 11 is turned off and the first motor 6 is started via the control panel 2. The output shaft of the first motor 6 drives the winding wheel 7 to rotate, so the steel wire rope 8 is wound around the winding wheel 7, lifting the fixing plate 9 upward. During the lifting process, the electromagnet 19 attracts and prevents the steel structure from sliding and falling off. The anti-slip rubber sleeve 15 of the outer frame increases the friction between the clamping block 14 and the steel structure. When the steel structure is lifted into place, the second motor 11 is turned off via the control panel 2. When motor 6 is activated, the electric slide rail 4 is started via control panel 2, allowing the steel structure to move laterally to a suitable position. Then, motor 6 is activated again via control panel 2, causing the output shaft of motor 6 to reverse, extending the wire rope 8. The fixed plate 9 then descends. During the downward movement, the abutment rod 23 contacts the ground. Subsequently, sleeve 21, spring 22, and abutment rod 23 form a damper to reduce vibration of the fixed plate 9. Then, electromagnet 19 is turned off via control panel 2, eliminating the magnetic force. Motor 11 is then activated, and the output shaft of motor 11 drives screw 12 to rotate counterclockwise, causing the moving frame 10 to move upward. The two clamps 14 move to the side away from the steel structure, releasing the steel structure, which then falls to the ground. During the hoisting process, the tilt angle of the fixed plate 9 can be detected by sensor 16. If the angle is too large, the data is transmitted to control panel 2, which activates warning light 3 to flash, alerting nearby personnel to stay away. If the steel structure needs to be hoisted again, the above operation can be repeated.
