DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figure 1-7As shown, a steel formwork lifting device includes a frame 1, two lifting rods 2 and a lifting member 3. The two lifting rods 2 are fixedly installed on the frame 1, the same connecting rod 4 is fixedly installed on the top of the two lifting rods 2, and the same lifting member 3 is slidably installed on the two lifting rods 2. A lifting component 5 is fixedly installed on the top of the frame 1, a fixed pulley 6 is fixedly installed at the bottom center of the connecting rod 4, a wire rope 7 is arranged between the lifting member 3 and the lifting component 5, a clamping ring 8 is fixedly installed at the top center of the lifting member 3, one end of the wire rope 7 is connected to the clamping ring 8, and the other end of the wire rope 7 passes around the fixed pulley 6 and is connected to the lifting component 5, and a limiting component 9 is slidably installed on the lifting member 3. The lifting assembly 5 serves as the power source of the entire device and is responsible for controlling the retraction and extension of the wire rope 7; the wire rope 7 serves as a medium for transmitting the power of the lifting assembly 5. When the lifting assembly 5 is started, the wire rope 7 will be retracted and extended according to the action of the lifting assembly 5, thereby pulling the lifting member 3 to slide on the lifting rod 2; the lifting rod 2 provides a sliding track for the lifting member 3 to ensure that the lifting member 3 remains vertical and stable during the lifting process. The connecting rod 4 not only connects the two lifting rods 2 to keep them synchronized, but also installs a fixed pulley 6 at the center of its bottom. The function of the fixed pulley 6 is to change the pulling direction of the wire rope 7, so that the lifting assembly 5 can be installed on the top of the frame 1 without being directly located above the lifting member 3, thereby increasing the flexibility and practicality of the device; the limit assembly 9 slidably installed on the lifting member 3 is used to ensure the stability and safety of the lifting member 3 during the lifting process, which can prevent the steel formwork from detaching from the lifting member 3 during the lifting process, further improving the safety of construction.

[0025] The lifting assembly 5 includes a box body 501, an I-shaped wheel 502, a first spur gear 503, a second spur gear 504 and a motor 505. The box body 501 is fixedly installed on the top of the frame 1, the I-shaped wheel 502 is rotatably installed inside the box body 501, the other end of the wire rope 7 is wound around the I-shaped wheel 502, the first spur gear 503 is fixedly installed on the I-shaped wheel 502, the motor 505 is fixedly installed inside the box body 501, the second spur gear 504 is meshed with the first spur gear 503, one end of the second spur gear 504 is rotatably installed on the inner wall of the box body 501, and the other end of the second spur gear 504 is fixedly connected to the output end of the motor 505. The box body 501 is fixedly installed on the top of the frame 1, providing a closed and stable working environment for the entire lifting assembly 5; the I-shaped wheel 502 is rotatably installed inside the box body 501, and its main function is to wind the wire rope 7. The other end of the wire rope 7 is wound on the I-shaped wheel 502. When the I-shaped wheel 502 rotates, the wire rope 7 will be retracted and released accordingly, thereby controlling the lifting and lowering of the lifting member 3. The first spur gear 503 is fixedly installed on the I-shaped wheel 502 and rotates with the rotation of the I-shaped wheel 502. This design enables the rotational power of the motor 505 to be transmitted to the I-shaped wheel 502, thereby driving the retraction and release of the wire rope 7. The motor 505 is fixedly installed inside the box body 501 to provide power for the entire lifting assembly 5. The output end of the motor 505 is fixedly connected to one end of the second spur gear 504, and the rotation of the motor 505 drives the first spur gear 503 to rotate. The second spur gear 504 rotates, and the second spur gear 504 is meshed with the first spur gear 503. When the motor 505 drives the second spur gear 504 to rotate, due to the meshing relationship between the gears, the first spur gear 503 will also rotate accordingly, thereby driving the I-shaped wheel 502 to rotate; through this design, the working power of the motor 505 is transmitted to the I-shaped wheel 502 through the gear transmission mechanism, thereby realizing precise control of the wire rope 7, thereby driving the lifting and lowering of the lifting member 3; through the precise control of the motor 505, combined with the transmission ratio of the gear transmission mechanism, precise control of the retraction and release of the wire rope 7 can be achieved, thereby ensuring that the lifting position and speed of the lifting member 3 meet the construction requirements; the gear transmission mechanism has high transmission efficiency and stability, and can maintain stable transmission performance under continuous working conditions, ensuring that the lifting process of the lifting member 3 is smooth and reliable.

[0026] The front and rear ends of the lifting member 3 are provided with a slide groove 10. The shape of the slide groove 10 is "L"-shaped. Since the steel template is placed on the inner side of the lifting member 3 during transportation, the limit component 9 can be lifted and lowered along the slide groove 10. When the limit component 9 reaches the top of the slide groove 10, it is pulled outward to the limit component 9, and the limit component 9 can be stuck in the slide groove 10, which is convenient for limiting the steel template and preventing the limit component 9 from sliding down along the slide groove 10 during the transportation of the steel template, thereby further improving the safety of the equipment.

[0027] The limiting assembly 9 includes two mounting blocks 901, a limiting member 902 and two sliders 903. One side of the two sliders 903 is fixedly mounted on the outer ends of the two mounting blocks 901. The two sliders 903 are slidably mounted in the two slide grooves 10. The inner sides of the two mounting blocks 901 are slidably mounted with the same limiting member 902. The interiors of the two mounting blocks 901 are fixedly mounted with racks 11, and nuts 12 are slidably mounted at both ends of the limiting member 902. The two nuts 12 are fixedly mounted with gears. Block 13, the tooth block 13 can be meshed with the rack 11, two screw rods 14 are rotatably installed inside the limit member 902, one end of the two screw rods 14 are respectively threadedly connected with two nuts 12, and the other ends of the two screw rods 14 are fixedly installed with a first bevel gear 15, a second bevel gear 16 is rotatably installed in the limit member 902, the second bevel gear 16 is meshed with the two first bevel gears 15, and a knob 17 is rotatably installed on the limit member 902, and the knob 17 is fixedly connected to the second bevel gear 16. By rotating the knob 17, the second bevel gear 16 is driven to rotate, and the second bevel gear 16 drives the two first bevel gears 15 to rotate, thereby accurately controlling the rotation of the screw rod 14, thereby driving the nut 12 to slide on the limit piece 902, and driving the tooth block 13 to move, so that the tooth block 13 is engaged with or disengaged from the rack 11. When the tooth block 13 and the rack 11 are engaged, the limit piece 902 is locked on the two mounting blocks 901. This design allows fine adjustment of the position of the limit piece 902 to ensure stable limiting of the steel template; through the operation of a single knob 17, the position of the limit piece 902 can be easily adjusted to meet the limiting requirements of steel templates of different thicknesses and different numbers.

[0028] The lower end of the lifting member 3 is inclined. When the steel template is placed in the lifting member 3, due to the effect of gravity, the steel template will naturally slide to the inside of the lifting member 3, preventing the steel template from detaching from the lower end of the lifting member 3 during transportation, thereby improving the safety of the equipment.
