Detailed implementation mode

[0027] The technical solution of the present utility model will be further described in detail below with reference to the accompanying drawings, but the protection scope of the present utility model is not limited to the following.

[0028] As Figures 1 to 7As shown, a wall painting auxiliary device comprises a base plate 1 and a lifting platform 2, wherein the lifting platform 2 is located above the base plate 1, and the base plate 1 is connected to the lifting platform 2 through a lifting mechanism, and a guardrail 3 is fixed along the edge of the top of the lifting platform 2, and a notch is provided on one side wall of the guardrail 3, and a storage platform 4 is provided at the notch, and one end of the storage platform 4 is hinged to the top of the guardrail 3, and a storage slot 5 is provided on the top of the storage platform 4. Since painting requires a variety of pigments and various types of painting pens, and since the traditional method of using a herringbone ladder cannot place painting tools, a tool table is generally prepared to place painting tools, and the painter needs to frequently go up and down the herringbone ladder to switch pigments or painting tools, which is very inconvenient. For this reason, a liftable lifting platform 2 is provided, and the lifting platform has enough space for the painter to move around, and the painter can use the herringbone ladder to move around. The user stands on the lifting platform 2 to perform painting operations. A staircase 24 is provided at the gap. The high end of the staircase 24 is fixed to the lifting platform 2. When in use, the lifting mechanism drives the lifting platform 2 to descend, so that the lifting platform 2 drives the staircase 24 to descend and touch the ground, and the storage platform 4 is deflected away from the guardrail 3 to open the gap. The user enters the lifting platform 2 through the staircase and the gap, and then deflects the storage platform 4 close to the guardrail 3 so that the storage platform is connected to the guardrail 3 to close the gap. The surroundings of the lifting platform 2 are closed by the guardrail 3 and the storage platform 4, so as to improve the protection effect and make it safer to use. The lifting platform 2 is driven up and down by the lifting mechanism to change the painting height, and the storage slot 5 on the storage platform 4 is used to place painting tools. The storage slot 5 can prevent the tools from tipping over and falling from a high place, and has higher safety. A plurality of universal wheels 6 are arranged at the bottom of the base plate 1, and an anti-skid plate 7 is arranged below the base plate 1. The anti-skid plate 7 has the freedom to move along the height direction of the base plate 1. An elastic friction plate 8 is fixed to the bottom of the anti-skid plate 7. The arrangement of the universal wheels 6 facilitates the movement of the auxiliary device. In order to further improve the stability and safety, an anti-skid plate 7 is designed. When painting, the anti-skid plate 7 is moved down so that the elastic friction plate 8 contacts the ground in a compressed state. The elastic friction plate 8 is made of rubber material and has a large friction coefficient. The positive pressure is increased by compressing the elastic friction plate 8, thereby greatly improving the friction between the elastic friction plate 8 and the ground, which can stabilize the auxiliary device well and ensure that there will be no accidental sliding during use, thereby improving stability and safety of use; the elastic friction plate 8 is connected to the anti-skid plate 7 with screws for easy replacement.

[0029] Furthermore, if Figure 1 As shown, the lifting platform 2 includes a top plate 25 and a horizontal slide 26. The top plate 25 is connected to the lifting mechanism. The horizontal slide 26 is slidably set on the top of the top plate 25. The guardrail 3 is installed on the horizontal slide 26. The user stands on the horizontal slide 26. The horizontal slide 26 can move horizontally on the top plate 25 to change the painting position in the horizontal direction, thereby increasing the painting range, eliminating the need to frequently move the device, and improving the painting efficiency.

[0030] Furthermore, if Figures 1 to 4 As shown, two C-shaped slide rails 27 are fixed in parallel on the top of the top plate 25, the openings of the two C-shaped slide rails 27 are arranged opposite to each other, and the two ends of the C-shaped slide rails 27 are sealed. The moving range of the horizontal slide plate 26 is limited by the C-shaped slide rails 27 with sealed ends. Within this range, the auxiliary device has good stability and will not tip over. The bottom of the horizontal slide plate 26 is rotatably provided with a front axle 28 and a rear axle 29, and wheels 30 are fixed at both ends of the front axle 28 and both ends of the rear axle 29. The wheels 30 are adapted to the C-shaped openings of the C-shaped slide rails 27. A motor 31 is installed on the top of the horizontal slide plate 26, and the output shaft of the motor 31 is connected to a first gear 32. The front axle 28 or the rear end 29 is provided with a first gear 32. A second gear 33 is connected, a window 34 is provided on the horizontal slide 26, the first gear 32 passes through the window 34 and meshes with the second gear 33, a battery is provided on the horizontal slide 26, the battery provides power for the motor 31, a switch for controlling the forward and reverse rotation of the motor 31 is provided on the guardrail 3, the motor 31 drives the first gear 32 to rotate, the first gear 32 drives the front axle 28 or the rear axle 29 to rotate by meshing with the second gear 33, so that the wheel 30 moves in the C-shaped slide rail 27, and then drives the horizontal slide 26 to slide horizontally on the top plate 25, so that the auxiliary device has the freedom of movement in the height and horizontal directions, has a larger painting range, and is more convenient to use.

[0031] Furthermore, if Figure 2 As shown, the lifting mechanism includes a hydraulic cylinder 9 and two groups of scissor-type telescopic assemblies 10. The two groups of scissor-type telescopic assemblies 10 are symmetrically arranged above the base plate 1. One end of the bottom of the scissor-type telescopic assembly 10 is hinged to the base plate 1, and the other end of the bottom is slidably connected to the base plate 1. One end of the top of the scissor-type telescopic assembly 10 is hinged to the lifting platform 2, and the other end is slidably connected to the lifting platform 2. The cylinder body of the hydraulic cylinder 9 is hinged on the base plate 1, and the hydraulic rod of the hydraulic cylinder 9 is hinged on one of the scissor-type telescopic assemblies 10. The sliding ends of the two scissor-type telescopic assemblies 10 are connected by a connecting rod, so that when the hydraulic cylinder 9 drives one of the scissor-type telescopic assemblies 10 to expand or contract, it can synchronously drive the other scissor-type telescopic assembly to move, so that the lifting mechanism drives the lifting platform 2 to move up and down.

[0032] Furthermore, if Figure 1 , Figure 2 and Figure 7As shown in the figure, a U-shaped plate 11 is fixed to the top of the bottom plate 1. The U-shaped plate 11 is located between two sets of scissor-type telescopic components 10 to avoid interference with the scissor-type telescopic components 10. A lead screw 12 is rotatably connected to the U-shaped plate 10. A rectangular groove 13 is formed through the bottom plate 1. A lifting column 14 is slidably fitted in the rectangular groove 13. A threaded hole 15 is formed at the top of the lifting column 14. The lead screw 12 is threadedly fitted in the threaded hole 15. The bottom of the lifting column 14 passes through the rectangular groove 13 and is connected to the anti-slip plate 7. A handwheel or a servo for connecting the lead screw 12 can be installed on the top of the U-shaped plate 11 to manually or electrically drive the lead screw 12 to rotate. Since the rotation degree of freedom of the lifting column 14 is restricted by the rectangular groove 13, the lifting column 14 moves linearly along the axial direction of the lead screw 12, so that the lifting column 14 drives the anti-slip plate 7 to move up and down to adjust the position of the elastic friction plate 8.

[0033] Furthermore, as Figures 1 to 6 shown in the figure, a hinge shaft 16 is vertically fixed to the bottom of the storage platform 4. The hinge shaft 16 is rotatably connected to the guardrail 3. A positioning lock shaft 17 is provided at one end of the bottom of the storage platform 4 away from the hinge shaft 16. The positioning lock shaft 17 has a degree of freedom to move in the height direction of the storage platform 4. A lock hole 18 is formed at the top of the guardrail 3. The lock hole 18 is located on the rotation path of the positioning lock shaft 17. An installation groove 19 is formed in the bottom of the storage platform 4. A spring 20 is arranged in the installation groove 19. One end of the positioning lock shaft 17 is slidably fitted in the installation groove 19. The two ends of the spring 20 are respectively connected to the storage platform 4 and the positioning lock shaft 17. A wedge surface 21 is provided on one side of the bottom of the positioning lock shaft 17 close to the guardrail 3. When the positioning lock shaft 17 is fitted in the lock hole 18, the spring 20 is in a normal state. A connecting rod 22 is fixed to the top of the positioning lock shaft 17. The connecting rod 22 passes through the top of the storage platform 4 and is fixed with a disc 23. When opening the storage platform 4, the connecting rod 22 is lifted through the disc 23. The connecting rod 22 drives the positioning lock shaft 17 to move upward, so that the positioning lock shaft 17 is disengaged from the lock hole 18, unlocking the rotation degree of freedom of the storage platform 4. Then, the storage platform 4 is deflected away from the guardrail 3 to open the notch. After the user stands on the lifting platform 2, the storage platform 4 is deflected close to the guardrail 3, so that the wedge surface 21 of the positioning lock shaft 17 first contacts the guardrail 3. Under the guidance of the wedge surface 21, the positioning lock shaft 17 moves upward to compress the spring 20, so that the positioning lock shaft 17 can cross the guardrail 3. When the positioning lock shaft 17 corresponds to the lock hole 18, the positioning lock shaft 17 automatically inserts into the lock hole 18 under the reaction force of the spring 20, thus locking the storage platform 4. When the user leans on the storage platform 4, the storage platform 4 will not move away from the guardrail 3 to open the notch, which has high safety.
