The connecting hole 1 30504 is a through hole, and the connecting hole 2 30505 is a blind hole. The diameter of the connecting hole 2 30505 is larger than the diameter of the connecting hole 1 30504. A fixing bolt 307 is installed in the connecting hole 1 30504, and the fixing bolt 307 is arranged in the threaded hole 2 30304 on the mounting circular hole 30303. The fixing bolt 307 fixes the fixing ring and the slider 303 together. The connecting rod 30502 is arranged in the movable groove 30403, and the control rod 30501 extends out of one end of the vertical rod and is fixedly connected to the control plate 308.

[0054] The diameter of the mounting rod 304 is equal to the diameter of the mounting hole 1 30102 and the mounting hole 2 30302. The upper ends of the two vertical rods 3 at the two ends of the support frame are fixedly connected to the connecting crossbar 207. A plurality of connecting vertical rods 208 are fixed parallel to the connecting crossbar 207 and the supporting crossbar 203.

[0055] The sliding groove 209 includes a first square groove 20901, with a second square groove 20902 at each end. The width of the second square groove 20902 is greater than that of the first square groove 20901. A transition groove 20903 is provided at the junction of the first square groove 20901 and the second square groove 20902. The depth L14 of the transition groove 20903 is less than L15, where L15 is half the difference in width between the second square groove 20902 and the first square groove 20901. In other words, the transition groove 20903 between the second square groove 20902 and the first square groove 20901 is not a smooth transition.

[0056] A plurality of lifting lugs 4 are fixed to the upper ends of the mobile frame 2 and the base frame 1 , and the lifting lugs 4 are used to connect height-adjusting cables.

[0057] When the construction workers find that there is a position on the working platform that they cannot reach, the mobile frame 2 needs to be moved on the base frame 1 so that the mobile frame 2 extends from the base frame 1. The specific operation process is as follows: in the initial state, the mobile railings 3 at both ends of the mobile frame 2 are set in the square groove 20902 near the end of the base frame 1. When the mobile frame 2 needs to be moved, the construction workers first move to the far end of the moving direction of the mobile frame 2. The construction workers pinch the two control plates 308 on the mobile railing 3, and the control plates 308 drive the control parts 305 on the rod body 1 30101 to move toward each other. The control ring 30503 at the end of the control part 305 drives the two sliders 3 03 move toward each other, so that the spring 306 between the mounting rod 304 and the two sliders 303 is compressed. When the two sliders 303 contact, that is, the connecting rod 30502 of the control member 305 moves to the end of the movable groove 30403, the operator now pushes the movable railing 3 from the square groove 2 20902 to the square groove 1 20901. The width L12 of the square groove 1 20901 is exactly equal to twice the thickness L6 of the slider 303. After the operator moves all the movable railings 3 at the far end into the square groove 1 20901, the control button can be turned on to drive the motor 5 to rotate forward. The drive motor 5 drives the screw 6 through the coupling. When the bearing rotates, the screw 6 rotates, and the thread on the screw 6 cooperates with the threaded hole 205 on the limit plate 204 at the lower end of the mobile frame 2, so that the mobile frame 2 moves on the base frame 1, thereby extending the mobile frame 2 until the mobile frame 2 moves the maximum moving distance and stops, so that the construction workers can continue to work on the places that are out of reach; when the mobile frame 2 needs to restore the initial position after the construction is completed, the construction workers turn on the control button to reverse the drive motor 5, and the drive motor 5 drives the screw 6 to rotate, so that the mobile frame 2 moves in the opposite direction, and when the end of the base frame 1 is in contact with the mobile railing 3 set in the square groove 20902 When the control panel 308 is pressed, the driving motor 5 can no longer drive the moving frame 2 to move. At this time, the driving motor 5 is automatically turned off, and the moving frame 2 returns to its initial position. The operator then moves the moving railing 3 that has just been moved into the square groove 20902. At this time, the operator does not need to press the control panel 308 again, but only needs to move the moving railing 3. When the slider 303 of the moving railing 3 enters the square groove 20902, under the elastic force of the spring 306 between the two sliders 303, the two sliders 303 move back to back, so that the two sliders 303 contact the side of the square groove 20902, thereby fixing the moving railing 3 in the square groove 20902 again.

[0058] In the initial state of the work platform, that is, when the lengths of the two ends of the mobile frame 2 extending from the base frame 1 are equal, the mobile railing 3 is located in the second square groove 20902, and the side surface of the mobile railing 3 contacts the end surface of the base frame 1. At this time, the relationship between the minimum distance L1 from the inner side surface of the vertical rod 3 of the mobile railing 3 to the mobile railing 3 and the minimum distance L2 from the mounting plate 109 to the limit plate 204 is as follows:

[0059] When L1 is greater than L2, when the movable frame 2 moves on the base frame 1 through the driving motor 5 and the lead screw 6, the movable frame 2 cannot move further after the mounting plate 109 contacts the limit plate 204. At this time, L2 is the maximum moving distance of the movable frame 2.

[0060] When L1 is equal to L2, when the movable frame 2 moves on the base frame 1 through the drive motor 5 and the lead screw 6, when the mounting plate 109 contacts the limit plate 204, the movable frame 2 cannot move further. At this time, the side surface of the movable railing 3 also contacts the end surface of the base frame 1. At this time, L1 or L2 is the maximum moving distance of the movable frame 2.

[0061] When L1 is less than L2, when the mobile frame 2 moves on the base frame 1 through the drive motor 5 and the lead screw 6, when the side of the moving railing 3 also just contacts the end face of the base frame 1, the mobile frame 2 cannot move further. At this time, L1 is the maximum moving distance of the mobile frame 2.

[0062] L1+L3=L4, L3 is the width of the rod body, L4 is the total length of square slot one 20901 and the two square slots two 20902; the maximum opening L9 of the two sliders 303 is equal to the distance L10 between the two movable slots 30403 on the mounting rod 304; the minimum length of the spring 306 is greater than twice the depth of the mounting circular hole; the free length of the spring 306 is greater than L9 + twice L10; the length L7 of the mounting slot 302 is equal to L9 + twice L6; the width L8 of the mounting slot 302 is equal to the width L5 of the slider 303; the width L13 of the square slot two 20902 is equal to the length L7 of the mounting slot 302.

[0063] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
