The other end of the steel cable 108 is fixed to a connecting post 109, which is fixed to the left end of the ramp 101. A lifting assembly for adjusting the height is provided at the upper end of the storage box 1. By starting the first motor 107, the winding roller 106 is driven to rotate, releasing the steel cable 108. Under the action of gravity, the ramp 101 rotates downward until the anti-slip post 104 contacts the roof. This allows workers to move to the roof through the ramp 101 to complete the maintenance, solving the problem that workers need to step onto the roof when maintaining the roof, which could lead to falls and injuries.

[0021] Please see Figure 1 and Figure 3In this embodiment, multiple fixed posts 5 are fixed at the upper corner of the workbench 2, and a guard plate 103 is fixed between two fixed posts 5. A first groove 3 is opened through the front end of the guard plate 103. A pulley 4 is rotatably arranged on the inner wall of the first groove 3. A steel cable 108 is arranged on the outer wall of the pulley 4. A support post 6 is fixed at the lower end of the storage box 1. A base plate 7 is fixed at the lower end of the support post 6. A tool cabinet 8 is fixed at the upper end of the base plate 7. Multiple tool boxes 9 are slidably arranged at the front end of the tool cabinet 8. A ladder 10 is fixed at the upper end of the base plate 7. By setting the pulley 4, the steel cable 108 can slide more smoothly and avoid tangling. By setting the ladder 10, it is convenient for the staff to move up and down between the base plate 7 and the workbench 2.

[0022] Please see Figure 4 and Figure 5 In this embodiment, the lifting assembly includes a screw 201, a second motor 202, a first slider 203, a fixed rod 204, a roller 205, and a second groove 206. The screw 201 is rotatably mounted on the inner wall of the storage box 1. The second motor 202 is fixedly connected to the right end of the storage box 1. The output shaft of the second motor 202 passes through the storage box 1 and is fixedly connected to the right end of the screw 201. The first slider 203 is threaded onto the outer wall of the screw 201. The lower end face of the first slider 203 is flush with the bottom of the inner wall of the storage box 1. The ends are fitted together. The first slider 203 is fixedly connected to the front and rear ends with a fixing rod 204. The other end of the fixing rod 204 is rotatably provided with a roller 205. The inner wall of the storage box 1 is provided with a second groove 206. The roller 205 is slidably disposed on the inner wall of the second groove 206. The lifting assembly also includes a first adjusting plate 207, a first mounting base 208, a second adjusting plate 209, a connecting rod 210, a second mounting base 211, a third groove 212, a second slider 213 and a third mounting base 214. A first adjusting plate 207 is rotatably mounted on the outer wall of the fixed rod 204. Multiple first mounting seats 208 are fixedly connected to the bottom of the inner wall of the storage box 1. A second adjusting plate 209 is rotatably mounted between two first mounting seats 208. A connecting rod 210 is rotatably mounted at the intersection of the first adjusting plate 207 and the first mounting seat 208. A second mounting seat 211 is fixedly connected to the lower end of the worktable 2. The other end of the first adjusting plate 207 is rotatably mounted inside the second mounting seat 211. A third groove 212 is opened at the lower end of the worktable 2. A second slider 213 is slidably mounted on the inner wall of the third groove 212. The other end of the second adjusting plate 209 is rotatably mounted outside the second slider 213. By starting the second motor 202, the screw 201 is driven to rotate, thereby causing the first slider 203 to drive the roller 205 to move left and right on the inner wall of the second groove 206. With the connection of the connecting rod 210, the second slider 213 slides on the inner wall of the third groove 212, thereby allowing the worktable 2 to move up and down to adjust its height.

[0023] In use, the second motor 202 is started to drive the screw 201 to rotate, thereby causing the first slider 203 to drive the roller 205 to move left and right on the inner wall of the second groove 206. With the connection of the connecting rod 210, the second slider 213 slides on the inner wall of the third groove 212, thereby allowing the worktable 2 to move up and down to adjust the height.

[0024] Once the designated height is reached, the first motor 107 is started to drive the take-up roller 106 to rotate, releasing the steel cable 108. Under the action of gravity, the ramp 101 rotates downward until the anti-slip post 104 contacts the roof, allowing workers to move to the roof via the ramp 101 to complete the maintenance.

[0025] Through the above steps, by starting the first motor 107 to drive the take-up roller 106 to rotate, the steel cable 108 is released. Under the action of gravity, the ramp 101 rotates downward until the anti-slip post 104 contacts the roof. This allows workers to move to the roof through the ramp 101 to complete the maintenance, solving the problem that workers need to step onto the roof when maintaining it, which could lead to them falling from a height and getting injured.
