[0025] Among them, the anti-displacement component 200 is installed on the base 100. Through the anti-displacement component 200, the support block 240 can be driven to move downward and contact the ground, so that the walking wheel 110 no longer contacts the ground, reducing the possibility of sliding or shaking of the lifting device when transporting materials.

[0026] See also Figure 1-Figure 2 The lower surface of the base 100 is rotatably connected with a walking wheel 110 , and two mounting plates 120 are installed on the upper surface of the base 100 , and a lifting bin 130 is slidably arranged between the two mounting plates 120 .

[0027] In this embodiment, the upper surfaces of the two mounting plates 120 are connected with second motors 140, the output shafts of the two second motors 140 are connected with screw rods 141, and the two sides of the lifting warehouse 130 are connected with fixed blocks 131, and the two fixed blocks 131 are respectively threadedly sleeved on the surfaces of the corresponding screw rods 141. In specific implementation, by starting the two second motors 140, the output shafts of the two drive the two screw rods 141 to rotate synchronously, and the two screw rods 141 will drive the corresponding fixed blocks 131 to move up and down, thereby driving the lifting warehouse 130 to move up and down, which is conducive to adjusting the height of the lifting warehouse 130 and transporting the materials to the designated position; a slide groove 121 is opened on the side of the mounting plate 120, and the fixed block 131 is in contact with the inner wall of the slide groove 121, and the screw rod 141 is located in the slide groove 121. In specific implementation, when the screw rod 141 rotates, the fixed block 131 can be moved up and down along the inner wall of the slide groove 121, reducing the possibility that the moving trajectory of the fixed block 131 will deviate during the movement.

[0028] See also Figure 1-Figure 4 The anti-displacement component 200 includes a first motor 210 and a rotating member 220. The first motor 210 is installed on one side of the base 100, and the output shaft of the first motor 210 is transmission-connected to the rotating member 220. The rotating member 220 is rotatably installed in the base 100, and a stud 230 is connected to the lower end of the rotating member 220. A support block 240 is threadedly sleeved on the surface of the stud 230. The support block 240 is slidably arranged inside the base 100. In specific implementation, by starting the first motor 210, its output shaft drives the rotating member 220 to rotate, and then drives the stud 230 to rotate, so that the support block 240 can move downward along the inside of the base 100, which is beneficial to the stability of the support block 240 during the movement, and the support block 240 will contact the ground, and the walking wheel 110 will no longer contact the ground, which is beneficial to improving the stability of the device on the ground and reducing the possibility of sliding or shaking of the lifting device when transporting materials.

[0029] In this embodiment, the output shaft of the first motor 210 is connected to the first bevel gear 211, and the first bevel gear 211 is transmission-connected to the rotating member 220; a cavity 150 is opened in the base 100, and the first bevel gear 211 and the rotating member 220 are both located in the cavity 150. In a specific implementation, the first bevel gear 211 and the rotating member 220 are arranged in the cavity 150 to reduce the possibility of the first bevel gear 211 and the rotating member 220 being affected by the outside world and being worn.

[0030] The rotating member 220 includes a connecting rod 221 and a second bevel gear 222. The connecting rod 221 is rotatably installed in the base 100, and the connecting rod 221 is respectively connected to the second bevel gear 222 and the stud 230, and the second bevel gear 222 is meshed and connected to the first bevel gear 211; a placement groove 160 is opened in the base 100, and the support block 240 is in contact with the inner wall of the placement groove 160. In a specific implementation, when the stud 230 rotates, the support block 240 can move up and down along the inner wall of the placement groove 160, which is beneficial to improve the stability of the support block 240 during the movement.

[0031] The inner wall of the placement groove 160 is connected to the limiting block 161, and the side of the support block 240 is connected to the protrusion 241, the protrusion 241 is in contact with the inner wall of the placement groove 160, and the protrusion 241 is located directly above the limiting block 161. In specific implementation, when the support block 240 moves downward, the protrusion 241 will move downward along the inner wall of the placement groove 160, which is beneficial to the stability of the protrusion 241 and the support block 240 during the movement, and the protrusion 241 will contact the limiting block 161, which can limit the protrusion 241 and the support block 240, thereby reducing the possibility of the support block 240 falling off the surface of the stud 230.

[0032] Specifically, the working principle of the construction safety lifting device is as follows: when in use, the lifting device can be moved by the walking wheel 110, which is conducive to moving the device to a specified position. By starting the first motor 210 on the base 100, its output shaft drives the first bevel gear 211 to rotate, and the first bevel gear 211 drives the second bevel gear 222 in the cavity 150 to rotate, thereby driving the connecting rod 221 and the stud 230 to rotate, so that the support block 240 can move downward along the inner wall of the placement groove 160, reducing the possibility that the moving trajectory of the support block 240 will deviate during the movement process, and the support block 240 will contact the ground, and the walking wheel 110 will no longer contact the ground, which is beneficial to the stability of the device on the ground and reduces the possibility of sliding or shaking of the lifting device when transporting materials. The material is placed in the lifting bin 130, and the second motor 140 on the mounting plate 120 is started so that its output shaft drives the screw rod 141 to rotate, thereby driving the fixed block 131 to move up and down along the inner wall of the slide groove 121, which is beneficial to the stability of the fixed block 131 during the movement, and the fixed block 131 will drive the lifting bin 130 to move up and down, which is beneficial to adjusting the height of the lifting bin 130 and transporting the material to the specified position.
