[0024] Example:
[0025] See also Figure 1-Figure 5, the utility model provides a technical solution:
[0026] A safe lifting device for housing construction comprises an adjusting base 1, wherein the adjusting base 1 is internally rotatably connected to a folding frame 2, an adjusting screw rod 3 is rotatably connected to the inner side of the folding frame 2 inside the adjusting base 1, the rear end of the bottom of the folding frame 2 is threadedly connected to the adjusting screw rod 3 through a connecting sleeve 4, a locking mechanism 5 is fixedly installed at the front end of the adjusting screw rod 3 and located on the front side of the adjusting base 1, a lifting platform 6 is rotatably connected to the top of the folding frame 2, a fixed frame 7 is fixedly installed on the top of the lifting platform 6, an extension frame 8 is slidably connected to the inner side of the fixed frame 7, an adjusting mechanism 9 is fixedly installed on the bottom of the fixed frame 7, and a standing basket 10 is fixedly installed on the top of the extension frame 8.
[0027] Firstly, movable seats 101 are fixedly installed at the four corners of the bottom of the adjustment base 1, and the bottoms of multiple groups of movable seats 101 are rotatably connected with movable wheels 102. The bottoms of multiple groups of movable seats 101 and the outer sides of the movable wheels 102 are threadedly connected with supporting feet 103. The movable wheels 102 at the bottom of the movable seats 101 are used to facilitate the movement of the adjustment base 1, so as to facilitate the adjustment of the position according to the construction site. When the device is in use, the movable wheels 102 are rotated downward to make them against the ground, so as to fix the adjustment base 1 and ensure the stability of the device when in use.
[0028] Furthermore, multiple groups of protective baffles 104 are fixedly installed on the outer side of the adjusting base 1, and the left and right ends of the inner sides of the multiple groups of protective baffles 104 are fixedly connected with telescopic rods 105, and the multiple groups of telescopic rods 105 are slidably connected to the adjusting base 1 through connecting tubes 106. Buffer springs 107 are movably installed on the inner side of the connecting tubes 106. When the device is in use, the outer side of the adjusting base 1 is protected by the multiple groups of protective baffles 104. When the outer side of the adjusting base 1 is impacted, the telescopic rods 105 can be extended and retracted to the inner side of the connecting tubes 106, and the impact force is buffered by the buffer springs 107, thereby avoiding the influence of external impact on the adjusting base 1, and further ensuring the stability of the device when in use.
[0029] Then, the front end of the bottom of the folding frame 2 is rotatably connected to the front end inside the adjusting base 1, and the two ends of the top of the folding frame 2 are rotatably connected to the bottom of the lifting platform 6. A first motor 301 is fixedly installed on the back of the adjusting base 1, and the driving end of the first motor 301 is fixedly connected to the rear end of the adjusting screw rod 3.

When rotating the adjusting screw 3 to adjust the height of the lifting platform 6, first pull the pull rod 503 to make the fixed tooth block 504 disengage from the outer side of the fixed gear 502, thereby releasing the fixation of the adjusting screw 3 and allowing it to rotate normally. After the adjustment of the lifting platform 6 is completed, release the pull rod 503, and under the reset of the reset spring 505, push the fixed tooth block 504 to fix the fixed gear 502, thereby fixing the adjusting screw 3, avoiding the danger of the adjusting screw 3 rotating during the use of the device. At the same time, the normal use of the adjusting screw 3 can be guaranteed by the crank 501 when the power is off.
[0031] Secondly, the bottom of the fixed frame 7 is fixedly connected to the lifting platform 6 through multiple groups of support rods 701, and the left and right ends of the extension frame 8 are slidably connected to the fixed frame 7 through the slide groove 702. The front and rear ends on the left and right sides of the extension frame 8 and the inner sides of the slide groove 702 are rotatably connected with rollers 801. The fixed frame 7 is fixedly installed on the lifting platform 6 through multiple groups of support rods 701. When the lifting platform 6 rises, the standing basket 10 rises accordingly. At the same time, the extension frame 8 can be moved horizontally by using the adjustment mechanism 9, thereby effectively increasing the operating space for construction personnel. When the extension frame 8 is moved, the extension frame 8 slides in the slide groove 702, and the roller 801 assists in rolling, thereby ensuring the movement stability of the extension frame 8.
[0032] Finally, the adjusting mechanism 9 includes a rotating drum 901 rotatably connected to the bottom of the fixing frame 7, the front and rear ends of the rotating drum 901 are rotatably connected to the fixing frame 7 through a second bearing seat 902, a second motor 903 is fixedly installed at the bottom of the fixing frame 7 and on the left side of the rotating drum 901, a driving gear 904 is fixedly connected to the driving end of the second motor 903, a driven gear 905 is fixedly sleeved on the outer side of the rear end of the rotating drum 901, the driving gear 904 is transmission-connected to the driven gear 905 through a transmission chain 906, a threaded rod 907 is connected to the internal thread of the rotating drum 901, and the front end of the threaded rod 907 is fixedly connected to the extension frame 8 through a connecting plate 908, the second motor 903 is started to drive the driving gear 904 to rotate, and the rotating drum 901 is driven to rotate under the transmission of the transmission chain 906 and the driven gear 905, when the rotating drum 901 rotates, it can drive the threaded rod 907 to extend forward, and drive the extension frame 8 to extend forward under the connection of the connecting plate 908, thereby effectively increasing the operating space for construction personnel.
[0033] In this embodiment, the implementation scenario is specifically as follows: when the device is in use, the first motor 301 is started to drive the adjusting screw rod 3 to rotate, and the rear end of the bottom of the folding frame 2 is driven to move forward under the connection of the connecting sleeve 4, thereby controlling the folding and extension of the folding frame 2, and then raising the lifting platform 6 to assist in high-position construction. When the device is in use, the outer side of the adjusting base 1 is protected by multiple sets of protective baffles 104, thereby preventing external impact from affecting the adjusting base 1. At the same time, after the adjustment of the lifting platform 6 is completed, the adjusting screw rod 3 is fixed by the locking mechanism 5 to avoid the danger of the adjusting screw rod 3 rotating during the use of the device. At the same time, when the power is off, the adjusting screw rod 3 can be ensured by the crank 501. When the rod 3 is used normally, the standing basket 10 rises when the lifting platform 6 rises, and the second motor 903 is started to drive the driving gear 904 to rotate, and the rotating drum 901 is driven to rotate under the transmission of the transmission chain 906 and the driven gear 905. When the rotating drum 901 rotates, it can drive the threaded rod 907 to extend forward, and drive the extension frame 8 to extend forward under the connection of the connecting plate 908, thereby effectively increasing the operating space for construction personnel. The whole operation process is simple and convenient. Compared with the existing safety lifting device for house construction, the utility model can improve the use stability of the safety lifting device for house construction through design, and at the same time effectively increase the operating space for construction personnel.
