Description

Technical Field

[0001] This utility model relates to the field of maintenance ladder technology, specifically to a house maintenance ladder. Background Technology

[0002] Home repair ladders are key tools designed specifically for the home repair industry. They are designed to ensure that repair personnel can safely and efficiently reach hard-to-reach areas of a house to perform professional tasks such as exterior wall repairs and roof tile replacements. By providing stable support and easy mobility, repair ladders not only improve the efficiency of repair work but also greatly ensure the safety of repair personnel.

[0003] Currently available house repair ladders neglect the need for repair personnel to carry multiple tools during actual operations. Repair personnel typically need to carry various tools such as screwdrivers, wrenches, and hammers when performing house repairs. However, existing house repair ladder designs do not provide suitable storage space for these tools, forcing repair personnel to place the tools on the ground or hang them on their bodies. This not only increases the complexity of the operation but may also cause safety hazards. Therefore, a new type of house repair ladder is proposed. Utility Model Content

[0023] like Figures 1 to 4 As shown, a house maintenance ladder includes two side bars 1 and a support plate 3. Several equidistant foot pedals 2 are fixedly installed between the two side bars 1. L-shaped frames 4 are rotatably installed on both sides of the support plate 3, and a rotating plate 5 is fixedly installed between the two L-shaped frames 4. A strip rod 7 is provided on the side of the support plate 3 near the foot pedals 2. A transmission assembly 8 for moving the support plate 3 left and right is installed inside the strip rod 7. Lifting assemblies 9 for raising and lowering the strip rod 7 are provided on the two side bars 1. A protective assembly 12 for preventing materials from falling is provided at the bottom of the support plate 3. It should be noted that when using this maintenance ladder, the side bars 1 should first be leaned against the wall, and then the rotating plate should be rotated. 5. Rotate the rotating plate 5 to a position perpendicular to the support plate 3, and simultaneously control the protective component 12 to unfold for protection. Then, place the toolbox and materials needed for maintenance on the surface of the support plate 3. When maintenance personnel climb the maintenance ladder, first control the transmission component 8 to move the support plate 3 to the left or right a certain distance to prevent the support plate 3 from blocking the foot pedal 2 and affecting the personnel's climbing. After the maintenance personnel climb to a certain height, control the lifting component 9 to drive the bar 7, transmission component 8, support plate 3, L-shaped frame 4, and rotating plate 5 to rise synchronously along the side bar 1 until the support plate 3 reaches a height that is convenient for the personnel to access the tools, and then stop.

[0024] like Figures 1 to 4 As shown, the transmission assembly 8 includes a strip groove 801. The strip rod 7 has a strip groove 801 on one side near the support plate 3. A lead screw 802 is movably installed inside the strip groove 801. A servo motor 803 for driving the lead screw 802 to rotate is fixedly installed at one end of the strip rod 7. A moving block 804 is threadedly connected to the lead screw 802. The moving block 804 is fixedly connected to the support plate 3. It should be noted that starting the servo motor 803 can drive the lead screw 802 to reciprocate. The reciprocating rotation of the lead screw 802 can cause the moving block 804 to move linearly back and forth. The linear reciprocating movement of the moving block 804 can drive the support plate 3 to move synchronously.

[0025] like Figures 1 to 4As shown, the lifting assembly 9 includes a strip-shaped hole 901. Each side rod 1 has a strip-shaped hole 901 on its side wall. A second lead screw 902 is movably installed inside each strip-shaped hole 901. A movable block 903 is threaded onto each second lead screw 902. Both movable blocks 903 are fixedly connected to the strip rod 7. An L-shaped rod 904 is fixedly installed at the bottom end of each side rod 1. A rotating shaft 905, coaxially rotating with the adjacent second lead screw 902, is movably installed at the bottom end of each side rod 1. A gear 906 is fixedly installed at the bottom end of each rotating shaft 905. A toothed belt 907 is fitted onto both gears 906, and the toothed belt 907 meshes with the two gears 906. The interior of the left L-shaped rod 904... A servo motor 908 is fixedly installed to drive the adjacent gear 906 to rotate. It should be noted that starting the servo motor 908 can drive the corresponding gear 906 to rotate reciprocally. The reciprocating gear 906 can drive another gear 906 to rotate reciprocally via the toothed belt 907. The two gears 906 drive the adjacent lead screw 902 to rotate via the corresponding rotating shaft 905. The reciprocating rotation of the lead screw 902 can cause the corresponding movable block 903 to move linearly back and forth. The two movable blocks 903 can drive the strip rod 7 to move linearly back and forth along the side rod 1. The strip rod 7 then drives the transmission assembly 8, the bearing plate 3, the L-shaped frame 4, and the rotating plate 5 to rise or fall synchronously along the side rod 1.

[0026] like Figures 1 to 4 As shown, each L-shaped frame 4 is threaded with a bolt 10, and the two sides of the bearing plate 3 are respectively provided with threaded grooves 11. It should be noted that when the rotating plate 5 is rotated to be perpendicular to the bearing plate 3, the two bolts 10 are rotated to connect the two bolts 10 to the inside of the corresponding threaded grooves 11, which can effectively fix the rotating plate 5.

[0027] like Figure 1 , Figure 3 , Figure 4As shown, the protective assembly 12 includes a square plate 1201. Two square plates 1201 are fixedly installed on the bottom of the support plate 3. Two rollers 1202 are movably installed in the middle of the two square plates 1201. Two gears 1203 are movably installed on the side wall of the square plate 1201 near the foot pedal 2. The two gears 1203 are meshed and connected. The two gears 1203 rotate coaxially with the two rollers 1202 respectively. A servo motor 1204 is fixedly installed on the bottom of the support plate 3. The output end of the servo motor 1204 is fixedly connected to the adjacent gear 1203. Two protective ropes 1205 of different lengths are fixedly installed on the side wall of each roller 1202. The free ends of both are fixedly connected to the bearing plate 3 and the rotating plate 5. It should be noted that starting the servo motor 1204 can drive the corresponding gear 1203 to rotate back and forth. The reciprocating gear 1203 can drive another gear 1203 to rotate back and forth, thereby causing the two rollers 1202 to rotate back and forth. The reciprocating rotation of the rollers 1202 will respectively wind up or unwind the two corresponding protective ropes 1205. When the rotating plate 5 rotates to be perpendicular to the bearing plate 3, the protective rope 1205 needs to be unwound. When the rotating plate 5 rotates to be horizontal to the bearing plate 3, the protective rope 1205 needs to be wound up. The protective rope 1205 can play a protective role to prevent items placed on the surface of the bearing plate 3 from falling.

[0028] like Figure 1 , Figure 2 As shown, the top of each side bar 1 is set with an outward convex arc surface, and the bottom of each L-shaped bar 904 is set with an outward convex arc surface. It should be noted that the arc surface design can provide more stable support on the ground.

[0029] In summary:

[0030] When using this maintenance ladder, first lean the side bar 1 against the wall, then rotate the rotating plate 5 until it is perpendicular to the support plate 3. At the same time, control the protective component 12 to unfold for protection. Then place the toolbox and materials needed for maintenance on the surface of the support plate 3. When maintenance personnel climb the ladder, first control the transmission component 8 to move the support plate 3 to the left or right a certain distance to prevent the support plate 3 from blocking the foot pedal 2 and affecting the personnel's climbing. After the maintenance personnel climb to a certain height, control the lifting component 9 to drive the bar 7, transmission component 8, support plate 3, L-shaped frame 4, and rotating plate 5 to rise synchronously along the side bar 1 until the support plate 3 reaches a height that is convenient for the personnel to access the tools.
