DETAILED DESCRIPTION

[0017] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0018] like Figure 1 and Figure 2As shown, the utility model provides a technical solution for a hoist for construction: comprising a bottom plate 13, a plurality of seats 11 are arranged at the bottom corners of the bottom plate 13, a support beam 12 is installed between adjacent seats 11, two groups of columns 21 are arranged on the bottom plate 13 in a relative manner, a cross beam 22 is arranged on the top of each group of columns 21, a lifting assembly is installed outside the cross beam 22, and the lifting assembly includes a motor 23, a main sprocket 24 is connected to the output end of the motor 23, a secondary sprocket 25 is arranged on the adjacent side of the main sprocket 24, a screw 27 is arranged in the shaft hole of the secondary sprocket 25, and the ends of the screw 27 are respectively connected to the cross beam 2 through the bearing seat 2. The bottom plate 13 is connected, the main sprocket 24 and the secondary sprocket 25 are connected by a chain 26, a chain protection shell 33 is arranged outside the main sprocket 24 and the secondary sprocket 25, the chain protection shell 33 is connected to the cross beam 22, a nut seat 28 is arranged outside the screw rod 27, a lifting platform 29 is installed outside the nut seat 28, the lifting platform 29 is L-shaped, and a plurality of reinforcing ribs 291 are arranged at equal intervals at the corners of the lifting platform 29, slide rails 31 are arranged on both sides of the screw rod 27, the slide rails 31 are installed outside the column 21, and a slide seat 32 is arranged on the slide rail 31, and the slide seat 32 is connected to the lifting platform 29.

[0019] In this embodiment, when in use, the construction personnel first install the construction hoist at the construction site, ensure that the stand 11 and the support beam 12 are stably supported on the ground, and provide a solid foundation for the hoist. Then, by operating the motor 23, the output end of the motor 23 drives the main sprocket 24 to rotate. The main sprocket 24 is connected to the secondary sprocket 25 through the chain 26, thereby driving the secondary sprocket 25 to rotate. A screw 27 is provided in the shaft hole of the secondary sprocket 25, and the screw 27 rotates with the rotation of the secondary sprocket 25. Since the ends of the screw 27 are connected to the cross beam 22 and the bottom plate 13 through the bearing seat, the screw 27 can move along its axial direction when rotating.

[0020] When the screw 27 rotates, the nut seat 28 moves along the axis of the screw 27, thereby driving the lifting platform 29 to rise and fall. The lifting platform 29 is L-shaped, and multiple reinforcing ribs 291 are arranged at the corners to increase the stability and load-bearing capacity of the lifting platform. During the lifting and lowering process of the lifting platform 29, the slide rail 31 and the slide seat 32 play a guiding and stabilizing role, ensuring that the lifting platform 29 rises and falls smoothly in the vertical direction.

[0021] In addition, the main sprocket 24 and the secondary sprocket 25 are provided to realize bidirectional lifting of the lifting platform 29. When it is necessary to lift an object, the motor 23 rotates forward to drive the main sprocket 24 and the secondary sprocket 25 to rotate, so that the lifting platform 29 is lifted; when it is necessary to lower an object, the motor 23 rotates reversely to lower the lifting platform 29. This bidirectional lifting design improves lifting efficiency and reduces operation time.

[0022] The utility model of the construction hoist realizes the smooth lifting and bidirectional lifting of the lifting platform in the vertical direction through the cooperation of the screw rod and the nut seat, as well as the main sprocket and the auxiliary sprocket connected by the chain. The hoist has the advantages of simple structure, convenient operation, high lifting efficiency, good construction safety, etc., and has broad application prospects and promotion value in the field of construction. At the same time, by setting the reinforcing rib plate and the slide rail slide seat, the stability and load-bearing capacity of the hoist are further enhanced, ensuring the safety and efficiency of construction.
