[0003] The prior art CN223016320U discloses a gantry crane with an anti-sway structure, including two supports, with a crossbeam fixedly connected to the upper end of the two supports. A lifting device is installed on the surface of the crossbeam, and a hook lock is installed on the surface of the lifting device. An adjustment structure is provided on the surface of the crossbeam. By adjusting the structure, two positioning plates are pressed against the upper surface of the hoisted item, and the positioning plates limit the hoisted item, which can effectively prevent the hoisted item from swinging.

[0004] However, the following shortcomings still exist in actual use: after the positioning plate is placed against the hoisted item, the position of the positioning plate is fixed and the height of the hoisted item cannot be adjusted. It can only be used for horizontal transportation, which is not very practical. Moreover, the height is adjusted by manually rotating the adjusting rod in the adjusting structure, which is inefficient.

[0005] Based on this, a portal steel structure hoisting and fixing device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figures 1-7As shown, a portal steel structure hoisting and fixing device includes two supports 100. An I-beam 200 is fixedly connected to the upper end of each support 100. A sliding mechanism is provided on each I-beam 200, connecting to a lifting component. Limiting components are provided on both supports 100 to prevent the lifting component from swinging. The lifting component is equipped with a gripping module for grabbing the hoisted item. The limiting components effectively prevent the lifting component from swinging during hoisting, improving the stability and safety of the hoisting process. The lifting component allows adjustment of the height of the hoisted item and the limiting components, solving the problem of existing devices being unable to adjust the height.

[0026] In this embodiment, as Figure 1 and Figure 3 As shown, the sliding mechanism includes a sliding frame 301, on which a plurality of movable wheels 302 are rotatably connected. The plurality of movable wheels 302 are rolled on the I-shaped crossbeam 200. One of the movable wheels 302 is driven by a motor 303, which is fixedly connected to the sliding frame 301. When the motor 303 is started, it drives the movable wheel 302 to rotate, thereby causing the sliding frame 301 to move horizontally along the I-shaped crossbeam 200 to complete the transportation of the hoisted items.

[0027] In one embodiment, such as Figure 2 and Figure 3 As shown, the lifting component includes a winding reel 401, which is rotatably connected to the lower end of the sliding frame 301. One end of the steel cable 402 is fixedly connected to the winding reel 401, and the other end of the steel cable 402 passes over a movable pulley 403 and is fixedly connected to the sliding frame 301. The movable pulley 403 is rotatably connected to the movable seat 404. The winding reel 401 is driven by a second motor 405, which is fixedly connected to the sliding frame 301. When the second motor 405 is working, it drives the winding reel 401 to rotate, thereby realizing the winding and unwinding of the steel cable 402. The steel cable 402 drives the movable pulley 403 to move up and down, and the movable pulley 403 drives the movable seat 404 to move up and down.

[0028] In one embodiment, such as Figure 1 , Figure 2 and Figure 4As shown, the limiting component includes a limiting rod 501, with two guide rods 502 slidably connected to both ends of the limiting rod 501. The guide rods 502 are fixedly connected to the bracket 100. The limiting rod 501 is provided with a limiting groove 503. The movable seat 404 is slidably connected in the limiting groove 503. The movable seat 404 has grooves 504 on both sides that cooperate with the limiting groove 503. A second movable wheel 505 is rotatably connected to the groove 504. The second movable wheel 505 is connected to the limiting rod 501. 1. The surfaces are in contact. The movable seat 404 is provided with an auxiliary unit. When horizontal movement is required, the sliding mechanism drives the movable seat 404 to slide in the limiting groove 503 to prevent it from swinging during movement. The auxiliary unit further limits the movable seat 404 to prevent it from continuing to slide along the limiting groove 503 due to inertia after the movement stops. When the height needs to be adjusted, the lifting component drives the movable seat 404 to move up and down, thereby driving the limiting rod 501 to slide up and down along the guide rod 502.

[0029] In one embodiment, such as Figure 2 and Figure 7 As shown, the auxiliary unit includes a locking block 601, which is slidably connected to a slot 602 on the inner wall of the groove 504. A spring 603 is provided in the slot 602, and the two ends of the spring 603 are respectively connected to the locking block 601 and the inner wall of the slot 602. A limiting tooth 604 that cooperates with the locking block 601 is fixedly connected to the inner wall of the limiting groove 503. The locking block 601 and the limiting tooth 604 are in close contact. When the moving seat 404 slides in the limiting groove 503, the limiting tooth 604 pushes the locking block 601 to move into the slot 602 and compresses the spring 603. When it moves to the next limiting tooth 604, the locking block 601 extends under the action of the spring and limits the moving seat 404 again, effectively preventing the moving seat 404 from continuing to slide along the limiting groove 503 due to inertia.

[0030] In one embodiment, such as Figure 4 and Figure 5As shown, the gripping module includes two rotating rods 701. One end of each rotating rod 701 is rotatably connected to the lower end of the movable seat 404, and the other end of each rotating rod 701 is rotatably connected to one end of a sliding rod 702. The other end of each sliding rod 702 is slidably connected to a sliding cylinder 703. A rotating rod 704 is rotatably connected to the middle of each rotating rod 701, and the other end of the rotating rod 704 is rotatably connected to the sliding cylinder 703. A clamping hook 705 is fixedly connected to the lower end of each sliding rod 702. A placement frame 706 for placing the suspended item is provided between the two clamping hooks 705. The placement frame 706 has clamping holes that cooperate with the clamping hooks 705. A fixing component is provided on the sliding cylinder 703. In the initial stage, the fixing component connects the sliding cylinder 703 and the movable seat 404 together, and the clamping hooks 705 are relatively far apart. During gripping, the lifting component moves the movable seat 404... 4. Lowering the slide cylinder 703 causes it to descend. The slide cylinder 703 first contacts the placement frame 706. The moving seat 404 continues to descend, causing the fixing component to disengage and the slide cylinder 703 to separate from the moving seat 404. At this time, the moving seat 404 moves upward. The moving seat 404 drives the sliding rod 702 to move into the slide cylinder 703 through the rotating rod 701, causing the two clamping hooks 705 to approach each other. The two clamping hooks 705 extend into the clamping holes on the placement frame 706, aligning the two parts. The placement frame 706 is clamped and fixed. When it is necessary to release the placement frame 706, the moving seat 404 is moved downward. The placement frame 706 contacts the ground. The moving seat 404 continues to descend. The moving seat 404 drives the sliding rod 702 to move outward of the sliding cylinder 703 through the rotating rod 701, so that the two clamping hooks 705 move away from each other, thereby releasing the placement frame 706. The moving seat 404 and the sliding cylinder 703 move closer to each other. The fixing component connects the moving seat 404 and the sliding cylinder 703.

[0031] In one embodiment, such as Figure 6As shown, the fixing assembly includes a connecting rod 801, which is fixedly connected to the upper end of the sliding cylinder 703. A hemispherical sphere 802 is fixedly connected to the upper end of the connecting rod 801. A sliding block 803 is slidably connected to the outer end of the connecting rod 801. Both the upper and lower ends of the sliding block 803 are inclined surfaces. The lower end of the movable seat 404 is fixedly connected to the fixing cylinder 804. The fixing cylinder 804 has four mounting slots 805, in which mounting elements are slidably connected. Mounting block 806 is fixedly connected to one end of spring 807, and the other end of spring 807 is connected to the inner wall of mounting groove 805. Hemisphere 802 has a connecting groove that matches the inclined surface on sliding block 803. In the initial stage, connecting rod 801 extends into fixed cylinder 804, and mounting block 806 is located between hemisphere 802 and sliding block 803. Due to the obstruction of hemisphere 802, connecting rod 801 cannot leave fixed cylinder 804. The sliding cylinder 703 is connected to the movable seat 404. When it is necessary to separate the sliding cylinder 703 from the movable seat 404, the movable seat 404 is moved downward, causing the fixed cylinder 804 to move downward. The mounting block 806 approaches the sliding block 803, and the upper inclined surface of the sliding block 803 gradually contacts and presses against the mounting block 806. The mounting block 806 retracts into the mounting groove 805. As the movable seat 404 moves, the mounting block 806 moves to the lower end of the sliding block 803 and is then pressed against the spring 806. Under the action of 7, the moving seat 404 moves upward, the fixed cylinder 804 moves upward, and the mounting block 806 drives the sliding block 803 to move upward along the connecting rod 801. When it moves to the hemisphere 802, the sliding block 803 is fixed due to the obstruction of the hemisphere 802. The lower inclined surface of the sliding block 803 gradually contacts and squeezes the mounting block 806, causing the mounting block 806 to retract into the mounting groove 805, thereby pulling the connecting rod 801 out of the fixed cylinder 804.

[0032] In one embodiment, such as Figure 5 As shown, the clamping hook 705 is equipped with a rubber pad 900 to enhance friction and prevent the hoisted object from slipping.

[0033] The above embodiment discloses a portal steel structure hoisting and fixing device, in which the item to be hoisted is placed in the placement frame 706, and the moving seat 404 is lowered by the lifting component, thereby driving the upper sliding cylinder 703 to descend. The sliding cylinder 703 first contacts the placement frame 706, and the moving seat 404 continues to descend, driving the fixing cylinder 804 to move downward. The mounting block 806 approaches the sliding block 803, and the upper inclined surface of the sliding block 803 gradually contacts and presses against the mounting block 806. The mounting block 806 retracts into the mounting groove 805. As the moving seat 404 moves, the mounting block 806 moves to the lower end of the sliding block 803 and extends under the action of the spring 807. At this time, the moving seat 404 moves upward, the fixing cylinder 804 moves upward, and the mounting block 806 drives the sliding block 803 to move upward along the connecting rod 801. When it moves to the hemisphere 802, the sliding block 803 is fixed due to the obstruction of the hemisphere 802, and the lower inclined surface of the sliding block 803 gradually contacts and presses against the mounting block 803. The mounting block 806 contacts and presses against the mounting groove 805, causing it to retract back into the mounting slot 805. This pulls the connecting rod 801 out of the fixed cylinder 804, separating the sliding cylinder 703 from the movable seat 404. At this point, the movable seat 404 moves upward, and the movable seat 404 drives the sliding rod 702 to move into the sliding cylinder 703 via the rotating rod 701. This causes the two clamping hooks 705 to approach each other and extend into the clamping holes on the placement frame 706, clamping and fixing the placement frame 706. The hoisted item is then lifted, and the sliding mechanism drives the hoisted item to move. The movable seat 404 slides in the limiting groove 503 to prevent it from swaying during movement. The auxiliary unit further limits the movable seat 404 to prevent it from continuing to slide along the limiting groove 503 due to inertia after the movement stops. When the height needs to be adjusted, the lifting component drives the movable seat 404 to move up and down, thereby causing the limiting rod 501 to slide up and down along the guide rod 502.

[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
