[0002] Construction refers to the production activities in the implementation stage of project construction, which is the construction process of various buildings. It can also be said to be the process of turning the various lines on the design drawings into physical objects at the designated location. Hoisting, which involves transporting building materials from the ground or a lower position to a higher position, or from one place to another, is a normal operation in construction.

[0003] The currently used hoisting devices still have the following problems: 1. When placing building materials, it is easy to place too many of them, resulting in the building materials being prone to falling during hoisting; 2.

Workers need to first observe the skew situation of the building materials after they are lifted and then adjust the hoisting position. It is impossible to pre-adjust the hoisting position, reducing the hoisting efficiency; 4. It is not convenient for workers to pre-sort the building materials to be hoisted, nor is it convenient to quickly unload the building materials after hoisting, affecting the hoisting efficiency.

[0015] Compared with the prior art, the hoisting device for building construction has the following beneficial effects: First, the present invention facilitates the staff to appropriately adjust the position of the adjustable hoisting seat, changes the center of gravity position during the hoisting of building materials, and is beneficial to improving the stability during hoisting; the setting of the circular magnet plays a limiting role on the positioning pin to prevent the positioning pin from falling off; when the hook on the hoisting device drives the adjustable hoisting seat to move upward, the rectangular frame remains stationary first, so that the top of the movable blocking cover is higher than the top of the rectangular frame, ensuring that there must be a certain distance between the building materials and the top of the movable blocking cover, reducing the occurrence of building materials falling; when the bottoms of the two rows of rectangular limit blocks contact the movable blocking cover, the rectangular frame and the movable blocking cover move upward simultaneously.

[0016] Second, when the bottoms of the two rows of rectangular limit blocks contact the movable blocking cover, the movable protective frame is in a horizontal state, which plays a blocking role on the building materials to prevent the building materials from falling during hoisting; when the tops of the two rows of rectangular limit blocks contact the movable blocking cover, the movable protective frame is in a vertical state, facilitating the staff to place and remove the building materials in the rectangular frame.

[0017] III. The rainwater on the building materials of the present invention can flow downward through a row of slot holes, achieving a centralized collection effect on the rainwater on the building materials; when it is necessary to clean the collected rainwater, the staff presses down one or more circular guide rods. At this time, the movable sealing plate moves downward, creating a gap between the movable sealing plate and the support base, and the collected rainwater can be discharged through the gap, preventing the rainwater on the building materials from dripping during hoisting; when the hoisting mechanism is slightly skewed to the left under the action of two arc-shaped protrusions, it indicates that the center of gravity of the building materials is on the left side of the center; when the hoisting mechanism is slightly skewed to the right under the action of two arc-shaped protrusions, it indicates that the center of gravity of the building materials is on the right side of the center. At this time, the staff presses the hoisting mechanism to make it tilt to the other side, and the staff judges the approximate position of the center of gravity of the building materials according to the pressing force. When the pressing force is large, the position of the adjustable hoisting seat can be adjusted more; when the pressing force is moderate, the position of the adjustable hoisting seat can be adjusted slightly; when the pressing force is small, the position of the adjustable hoisting seat can be not adjusted, realizing the pre-adjustment of the hoisting position and improving the hoisting efficiency of the building materials.

[0018] IV. The provision of the movable connecting frame of the present invention plays a limiting role on the support base, facilitating the staff to connect the support base with the rectangular frame; the provision of a row of helical springs B enables the movable connecting frame to move only after being stressed, ensuring the connection effect between the support base and the rectangular frame. In addition, when the building materials are of a rectangular structure and it is convenient for the staff to arrange the building materials in sequence, after hoisting is completed, the staff can pull out the two movable connecting frames outward to separate the support base from the rectangular frame, facilitating the rapid unloading of the building materials; at the same time, when hoisting the building materials, the staff can pre-arrange the building materials on another set of support mechanisms, saving the time for placing and taking out the building materials and improving the hoisting efficiency of the building materials.

[0027] Please refer specifically to Figure 1 and Figure 8 As shown in FIGS. and

[0027] , the connecting mechanism 400 includes: a mounting frame 401 and a movable connecting frame 402; the mounting frame 401 is fixedly installed on the outer wall of the rectangular frame 101; the movable connecting frame 402 is slidably installed on the mounting frame 401 and the rectangular frame 101, and a chamfer is provided at the inner end of the movable connecting frame 402, and the inner end of the movable connecting frame 402 is inserted into the support base 301; the connecting mechanism 400 further includes: a reset flat plate 403 and a spiral spring B404; the reset flat plate 403 is fixedly installed on the movable connecting frame 402, and the inner side of the reset flat plate 403 is in contact with the rectangular frame 101; a row of spiral springs B404 are provided, and a row of spiral springs B404 are sleeved on the outside of the movable connecting frame 402, and a row of spiral springs B404 are located between the mounting frame 401 and the reset flat plate 403; Its specific functions are as follows: Since the movable connecting frame 402 is slidably installed on the mounting frame 401 and the rectangular frame 101, and a chamfer is provided at the inner end of the movable connecting frame 402, and the inner end of the movable connecting frame 402 is inserted into the support base 301, it plays a limiting role on the support base 301, facilitating the connection of the support base 301 and the rectangular frame 101 by the staff; the arrangement of a row of spiral springs B404 enables the movable connecting frame 402 to move only after being stressed, ensuring the connection effect between the support base 301 and the rectangular frame 101; In addition, when the building material is of a rectangular structure and it is convenient for the staff to arrange the building materials in sequence, after the lifting is completed, the staff can pull the two movable connecting frames 402 outwards to separate the support base 301 from the rectangular frame 101, facilitating the rapid unloading of the building materials. At the same time, when the building materials are being lifted, the staff can pre-arrange the building materials on another set of support mechanisms 300, saving the time for placing and taking out the building materials and improving the lifting efficiency of the building materials.

[0028] Working principle: The staff appropriately adjusts the position of the adjustable lifting seat 105, changing the center of gravity position of the building materials during lifting, which is beneficial to improving the stability during lifting. The setting of the circular magnet 107 plays a limiting role on the positioning pin 106 to prevent the positioning pin 106 from falling off. Then, the adjustable lifting seat 105 is connected to the hook on the lifting equipment. When the hook on the lifting equipment drives the adjustable lifting seat 105 to move upwards, the rectangular frame 101 remains stationary first, making the top of the movable blocking cover 102 higher than the top of the rectangular frame 101, ensuring that there must be a certain distance between the building materials and the top of the movable blocking cover 102, reducing the occurrence of the building materials falling. When the bottoms of the two rows of rectangular limit blocks 103 come into contact with the movable blocking cover 102, the rectangular frame 101 and the movable blocking cover 102 move upwards simultaneously. When the bottoms of the two rows of rectangular limit blocks 103 come into contact with the movable blocking cover 102, the movable protective frame 202 is in a horizontal state, playing a blocking role on the building materials to prevent the building materials from falling during lifting. When the tops of the two rows of rectangular limit blocks 103 come into contact with the movable blocking cover 102, the movable protective frame 202 is in a vertical state, facilitating the staff to place and take out the building materials in the rectangular frame 101. The rainwater on the building materials can flow downward through a row of slot holes, achieving a centralized collection effect on the rainwater on the building materials. When it is necessary to clean the collected rainwater, the staff presses down one or more circular guide rods 303. At this time, the movable sealing plate 304 moves downward, creating a gap between the movable sealing plate 304 and the support base 301, and the collected rainwater can be discharged through the gap, preventing the rainwater on the building materials from dripping during lifting. It is convenient for the staff to judge the center of gravity position of the building materials during lifting. When the lifting mechanism 100 is slightly tilted to the left under the action of the two arc-shaped protrusions 3011, it indicates that the center of gravity of the building materials is to the left of the center. When the lifting mechanism 100 is slightly skewed to the right under the action of the two arc-shaped protrusions 3011, it indicates that the center of gravity of the building material is on the right side of the center. At this time, the staff presses the lifting mechanism 100 to make the lifting mechanism 100 tilt to the other side. The staff judges the approximate position of the center of gravity of the building material according to the pressing force. When the pressing force is large, the position of the adjustable lifting seat 105 can be adjusted more; when the pressing force is average, the position of the adjustable lifting seat 105 can be adjusted slightly; when the pressing force is small, the position of the adjustable lifting seat 105 can be not adjusted, realizing the pre-adjustment of the lifting position and improving the lifting efficiency of the building material; When the building material is of a rectangular structure and it is convenient for the staff to arrange the building materials in sequence, after the lifting is completed, the staff can pull the two movable connecting frames 402 outwards to separate the support base 301 from the rectangular frame 101, facilitating the rapid unloading of the building materials; at the same time, when the building materials are lifted, the staff can pre-arrange the building materials on another set of support mechanisms 300, saving the time for placing and taking out the building materials and improving the lifting efficiency of the building materials.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
