[0025] As Figure 1 shown, a lifting device for decoration engineering includes a bottom box 1. An elevator 1.1 is provided on the upper outer wall of the bottom box 1. A standing platform 1.2 is provided at the top of the elevator 1.1. U-shaped frames 1.3 are fixedly connected to both the front and rear sides of the elevator 1.1 on the upper outer wall of the bottom box 1. A plurality of equally spaced blocking rods 1.31 are fixedly connected between the inner walls on both sides of the U-shaped frame 1.3. Fixed seats 1.4 are fixedly connected to both the front and rear side walls of the standing platform 1.2. An anti-falling component 2 is provided on the fixed seat 1.4. An anti-slip component 3 is provided inside the bottom box 1.

[0026] Specifically, as Figure 2 and Figure 3As shown in the figure, for the lifting device used in the decoration project, the anti-falling component 2 includes a groove 2.1, an anti-falling block 2.2, a support platform 2.3, a telescopic rod 2.4, a spring 2.5, a mounting block 2.6, a T-shaped mounting groove 2.61, a reinforcing block 2.7 and a T-shaped slide rail 2.71. A groove 2.1 is formed on the side wall of the fixed seat 1.4 away from the standing platform 1.2. An anti-falling block 2.2 is rotatably arranged between the two side walls of the groove 2.1. Two symmetrically distributed support platforms 2.3 are fixedly connected to the side wall of the fixed seat 1.4 away from the standing platform 1.2 and below the groove 2.1. A telescopic rod 2.4 is hinged on the support platform 2.3. The telescopic end of the telescopic rod 2.4 is hinged to the anti-falling block 2.2. A spring 2.5 is sleeved on the outside of the telescopic rod 2.4. One end of the spring 2.5 is fixedly connected to the support platform 2.3 and the other end is fixedly connected to the anti-falling block 2.2. Two symmetrically distributed mounting blocks 2.6 are fixedly connected to the side wall of the fixed seat 1.4 away from the standing platform 1.2 and above the groove 2.1. A T-shaped mounting groove 2.61 is formed in the mounting block 2.6. A T-shaped slide rail 2.71 is slidably arranged in the T-shaped mounting groove 2.61. A reinforcing block 2.7 is fixedly connected to the bottom wall of the T-shaped slide rail 2.71. During the process of the elevator 1.1 driving the standing platform 1.2 to rise, the anti-falling block 2.2 rotates along its connection point with the groove 2.1 under the block of the blocking rod 1.31. The telescopic end of the telescopic rod 2.4 contracts, and the spring 2.5 is compressed. When the anti-falling block 2.2 passes through the blocking rod 1.31, it resets under the push of the spring 2.5, so that the anti-falling block 2.2 is always between the two blocking rods 1.31. Once a fall occurs, the standing platform 1.2 drives the fixed seat 1.4 to move downward. During the downward movement, blocked by the blocking rod 1.31, the anti-falling block 2.2 becomes horizontal. The mounting block 2.6 can improve the load-bearing capacity of the anti-falling block 2.2 when it falls. Blocked by the blocking rod 1.31, the standing platform 1.2 will stop falling, fully protecting the lives of workers.

[0027] Specifically, as Figure 4As shown in the figure, for the lifting device used in decoration projects, the anti-slip component 3 includes a screw rod 3.1, a worm gear 3.2, a motor 3.3, a worm 3.4, a lifting plate 3.5, a driving cylinder 3.6 and moving wheels 3.7. A screw rod 3.1 is rotatably provided at the center of the upper inner wall of the bottom box 1. A worm gear 3.2 is fixedly sleeved on the upper end of the screw rod 3.1. A motor 3.3 is installed on the rear outer wall of the bottom box 1. The output shaft of the motor 3.3 extends into the bottom box 1 and is fixedly connected to a worm 3.4 that cooperates with the worm gear 3.2. The other end of the worm 3.4 is rotatably connected to the front inner wall of the bottom box 1. A lifting plate 3.5 is slidably arranged inside the bottom box 1. A driving cylinder 3.6 is fixedly connected to the center of the upper side wall of the lifting plate 3.5. The lower end of the screw rod 3.1 extends into the driving cylinder 3.6 and is threadedly connected to its inner wall. Moving wheels 3.7 are respectively installed at the four corners of the bottom wall of the lifting plate 3.5. Before operation, the output shaft of the motor 3.3 can drive the worm 3.4 to rotate. When the worm 3.4 rotates, it can make the worm gear 3.2 drive the screw rod 3.1 to rotate. When the screw rod 3.1 rotates, it can make the driving cylinder 3.6 drive the lifting plate 3.5 to move upward, so that the moving wheels 3.7 retract into the bottom box 1, and the bottom wall of the bottom box 1 touches the ground to form a stable support, increasing the contact area with the ground and making the operation more stable. When it is necessary to move, the motor 3.3 can be reversed. After transmission, the lifting plate 3.5 drives the moving wheels 3.7 to move downward. After the bottom box 1 is lifted, it can be moved, which is more flexible.

[0028] Specifically, as Figure 2 shown in the figure, for the lifting device used in decoration projects, a plurality of ball bearings 2.21 are arranged on both sides of the upper and lower side walls of the anti-falling block 2.2 to avoid frequent friction between the anti-falling block 2.2 and the blocking rod 1.31.

[0029] Specifically, as Figure 5 shown in the figure, for the lifting device used in decoration projects, guide grooves 1.32 are respectively opened on both sides of the side wall of the U-shaped frame 1.3 close to the standing platform 1.2. Two guide rods 1.21 that cooperate with the guide grooves 1.32 are fixedly connected to both the front and rear side walls of the standing platform 1.2. When the standing platform 1.2 moves up and down, the guide rods 1.21 will slide in the guide grooves 1.32 to guide the standing platform 1.2 and make the standing platform 1.2 more stable.

[0030] Specifically, as Figure 2 shown in the figure, for the lifting device used in decoration projects, four reinforcing plates are respectively arranged in a ring between the two ends of the blocking rod 1.31 and the U-shaped frame 1.3 to make the blocking rod 1.31 stronger.

[0031] In the specific implementation of the present utility model, the worker stands on the standing platform 1.2, and the elevator 1.1 drives the standing platform 1.2 to rise. During the rising process, the anti-falling block 2.2 rotates along its connection point with the groove 2.1 under the block of the blocking rod 1.31, the telescopic end of the telescopic rod 2.4 contracts, and the spring 2.5 is compressed. When the anti-falling block 2.2 passes through the blocking rod 1.31, it resets under the push of the spring 2.5, so that the anti-falling block 2.2 is always between the two blocking rods 1.31. Once a fall occurs, the standing platform 1.2 drives the fixed seat 1.4 to move downward. During the downward movement, blocked by the blocking rod 1.31, the anti-falling block 2.2 becomes horizontal. The mounting block 2.6 can improve the load-bearing capacity of the anti-falling block 2.2 when it falls. Blocked by the blocking rod 1.31, the standing platform 1.2 will stop falling, fully protecting the life safety of the worker. When the elevator 1.1 descends normally, the reinforcement block 2.7 can be removed from the mounting block 2.6. Before the operation, the motor 3.3 is started. The output shaft of the motor 3.3 can drive the worm 3.4 to rotate. The rotation of the worm 3.4 can cause the worm gear 3.2 to drive the screw 3.1 to rotate. When the screw 3.1 rotates, it can drive the driving cylinder 3.6 to drive the lifting plate 3.5 to move upward, so that the moving wheel 3.7 retracts into the inner part of the bottom box 1, and the bottom wall of the bottom box 1 touches the ground to form a stable support, increasing the contact area with the ground and making the operation more stable. When it is necessary to move, the motor 3.3 can be reversed. After transmission, the lifting plate 3.5 drives the moving wheel 3.7 to move downward, and the bottom box 1 can be lifted and then moved, which is more flexible.
