[0012] The operation method of the device: Step 1: Automatic opening. When the user climbs through the main body of the climbing device, the main body of the climbing device can be monitored by the first opening sensor, and then the electric push rod is controlled by the main controller to work. The first cover plate and the second cover plate can be rotated by shortening the electric push rod, so that the first cover plate and the second cover plate are opened. When the user passes through the working platform, the main controller controls the electric push rod to extend, and then the first cover plate and the second cover plate are closed. When the user goes down through the main body of the climbing device, the main body of the climbing device is monitored by the second opening sensor, and the electric push rod is controlled by the main controller to work, so that the first cover plate and the second cover plate are opened. When the user and the main body of the climbing device pass through the working platform, the first cover plate and the second cover plate are closed; Step 2: The machine opens automatically. When the first opening sensor or the second opening sensor has a problem, the detection opener monitors that the second cover is in a stationary state. At this time, the detection opener enables the first pressure switch or the second pressure switch to work through the main controller. When the main body of the free climbing device moves up, after the main body of the free climbing device conflicts with the first inclined plate at the bottom inclined surface of the first inclined surface receiving block, the first inclined plate can press down the first pressure switch, and the electric push rod is controlled to work through the first pressure switch, and the first cover and the second cover are opened again through the electric push rod. When the main body of the free climbing device and the user pass through the working platform, the first cover and the second cover are closed again. When the main body of the free climbing device moves down, the main body of the free climbing device conflicts with the second inclined plate at the top inclined surface of the second inclined surface receiving block, and the second pressure switch is pressed down through the second inclined plate, so that the first cover and the second cover are opened. At the same time, the second inclined surface receiving block slides toward the inside of the second receiving groove. When the main body of the free climbing device and the user pass through the working platform, the first cover and the second cover are closed again. Step 3: Manual opening. When there is a problem with the electric push rod or the main controller, the user pulls the pull plate, and the pull plate drives the slider and the fixed slide to move through the connecting block. When one end of the fixed slide is no longer in the fixed groove, the user can open the second cover plate through the handle, and then pass through the working platform.

[0013] Compared with the prior art, the present invention has the following beneficial effects: When the user is using the present device, when the user is climbing through the main body of the free climbing device, the main body of the free climbing device can be monitored by the first opening sensor, and then the main controller controls the electric push rod to work, and the shortening of the electric push rod can make the first cover plate and the second cover plate rotate, thereby opening the first cover plate and the second cover plate, thereby facilitating the main body of the free climbing device and the user to pass through the working platform. After the user passes through the working platform, the main controller controls the electric push rod to extend, and then the first cover plate and the second cover plate are closed. When the user goes down through the main body of the free climbing device, the main body of the free climbing device is monitored by the second opening sensor, and the main controller controls the electric push rod to work, thereby opening the first cover plate and the second cover plate. When the user and the main body of the free climbing device pass through the working platform, the first cover plate and the second cover plate are opened. The second cover is closed, which facilitates the user's maintenance work. When the first opening sensor or the second opening sensor has a problem, the detection opener can monitor that the second cover is in a stationary state. At this time, the detection opener makes the first pressure switch or the second pressure switch work through the main controller. When the main body of the non-climbing device moves up, when the main body of the non-climbing device conflicts with the first inclined plate at the inclined surface of the bottom end of the first inclined surface receiving block, the first inclined plate rotates to one side of the first pressure switch and compresses the first torsion spring at the same time. The rotating first inclined plate can press down the first pressure switch, and the electric push rod is controlled to work through the first pressure switch. The first cover and the second cover are opened by the electric push rod. After one end of the main body of the non-climbing device conflicts with the inclined surface of the first inclined surface receiving block, When the first inclined surface receiving block is in contact with the first inclined surface receiving block, the first inclined surface receiving block is compressed by the first spring, and when one end of the free climbing device body no longer conflicts with the first inclined surface receiving block, the first inclined surface receiving block is reset under the action of the first spring, and when the free climbing device body and the user pass through the working platform, the first cover plate and the second cover plate are closed again, and when the free climbing device body continues to move up, the free climbing device body conflicts with the inclined surface on one side of the bottom end of the second inclined surface receiving block, causing the second inclined surface receiving block to move toward the inside of the second receiving groove, thereby not touching the second inclined plate and the second pressure switch at one end of the second inclined surface receiving block, and when the free climbing device body moves downward, the free climbing device body conflicts with the second inclined plate at the inclined surface at the top end of the second inclined surface receiving block, and presses down the second pressure switch through the second inclined plate, thereby causing the first cover plate to When the user moves the first cover plate to the second position, the first and second cover plates are in a closed position, and the user moves the first cover plate to the second position, and the user moves the second cover plate to the second ...The pull plate drives the slider and the fixed slide plate to move through the connecting block. When one end of the fixed slide plate is no longer in the fixed groove, the user can open the second cover plate through the handle, and then pass through the working platform. The pull plate, the slider and the fixed slide plate can ensure that the user can open the second cover plate at any time, further ensuring the normal use of the device, and will not affect the user's maintenance work. The device can automatically open and close the work in a timely and effective manner, and will not affect the normal use of the main body of the non-climbing device. At the same time, if a failure occurs in the device, the electric push rod can also be mechanically controlled to ensure the normal opening and closing of the first cover plate and the second cover plate. If a failure occurs in the electric push rod in the device, the user can also mechanically open and close the second cover plate, further ensuring the normal use of the device, without worrying that the user cannot open the second cover plate in a timely and effective manner, thereby reducing the user's workload and working time, and thus improving the user's work efficiency. At the same time, when multiple people are working, there is no need to worry that the main body of the non-climbing device cannot return. , BRIEF DESCRIPTION OF THE DRAWINGS

The ends of the first cover plate 7 and the second cover plate 8 that are close to each other are both L-shaped, and the second cover plate 8 and one end of the first cover plate 7 are adapted to each other. One end of the second cover plate 8 is adapted to the ladder 3, which is convenient for the first cover plate 7 to drive the second cover plate 8 to rotate. The upper and lower ends of the first inclined surface receiving block 16 away from the first spring 17 are both inclined. The first inclined plate 19 is located at the inclined surface at the bottom end of one side of the first inclined surface receiving block 16, and the upper and lower ends of the second inclined surface receiving block 26 away from the second spring 27 are both inclined. The second inclined plate 30 is located at the inclined surface at the top of one side of the first inclined surface receiving block 16, which can ensure the normal movement of the non-climbing device body 5, and can also ensure that the non-climbing device body 5 can normally open the first cover plate 7 and the second cover plate 8. The control end of the electric push rod 11 is electrically connected to the main controller 6 through the first pressure switch 22 and the second pressure switch 29, and the control end of the first pressure switch 22 and the second pressure switch 29 is electrically connected to the main controller 6 through the detection opener 12, which is convenient for the device to work automatically. The sizes of the fixed slide plate 40 are respectively adapted to the fixed groove 33 and the through groove 36, the sizes of the slider 37 are respectively adapted to the slide groove 34, and the sizes of the connecting block 39 are respectively adapted to the connecting groove 35. The adapted sizes can ensure the stability of the movement of the fixed slide plate 40, the slider 37 and the connecting block 39; The device operates as follows: Step 1: Automatic opening. When the user climbs through the main body 5 of the climbing-free device, the main body 5 of the climbing-free device can be monitored by the first opening sensor 14, and then the electric push rod 11 is controlled to work by the main controller 6. The first cover plate 7 and the second cover plate 8 can be rotated by shortening the electric push rod 11, so that the first cover plate 7 and the second cover plate 8 are opened. When the user passes through the working platform 2, the main controller 6 controls the electric push rod 11 to extend, and then the first cover plate 7 and the second cover plate 8 are closed. When the user goes down through the main body 5 of the climbing-free device, the main body 5 of the climbing-free device is monitored by the second opening sensor 24, and the electric push rod 11 is controlled to work by the main controller 6, so that the first cover plate 7 and the second cover plate 8 are opened. When the user and the main body 5 of the climbing-free device pass through the working platform 2, the first cover plate 7 and the second cover plate 8 are closed; Step 2: Automatic mechanical opening. When the first opening sensor 14 or the second opening sensor 24 has a problem, the detection opener 12 detects that the second cover plate 8 is in a stationary state. At this time, the detection opener 12 causes the first pressure switch 22 or the second pressure switch 29 to work through the main controller 6. When the climb-free device body 5 moves upward, when the climb-free device body 5 contacts the first inclined plate 19 at the bottom inclined surface of the first inclined surface receiving block 16, the first inclined plate 19 can press down the first pressure switch 22, and the electric push rod 11 is controlled to work through the first pressure switch 22. The first cover plate 7 and the second cover plate 8 are opened again. When the climbing-free device body 5 and the user pass through the working platform 2, the first cover plate 7 and the second cover plate 8 are closed again. When the climbing-free device body 5 moves downward, the climbing-free device body 5 contacts the second inclined plate 30 at the top inclined surface of the second inclined surface receiving block 26, and the second pressure switch 29 is pressed downward by the second inclined plate 30, so that the first cover plate 7 and the second cover plate 8 are opened. At the same time, the second inclined surface receiving block 26 slides toward the inside of the second receiving groove 25. When the climbing-free device body 5 and the user pass through the working platform 2, the first cover plate 7 and the second cover plate 8 are closed again. Step three: Manual opening. When a problem occurs with the electric push rod 11 or the main controller 6, the user pulls the pull plate 41, and the pull plate 41 drives the slider 37 and the fixed slide plate 40 to move through the connecting block 39. When one end of the fixed slide plate 40 is no longer in the fixed groove 33, the user can open the second cover plate 8 through the handle 9, and then pass through the working platform 2.

[0018] Working principle: When the user is using the present device, when the user is climbing through the climbing-free device body 5, the first opening sensor 14 can monitor the climbing-free device body 5, and then the main controller 6 controls the electric push rod 11 to work, and the electric push rod 11 is shortened, and the connecting member 10 is pulled by the electric push rod 11, and the connecting member 10 pulls one end of the first cover plate 7, so that the first cover plate 7 and the second cover plate 8 can be rotated, so that the first cover plate 7 and the second cover plate 8 are opened, so as to facilitate the climbing-free device body 5 and the user to pass through the working platform 2. When the user passes through the working platform 2, the main controller 6 controls the electric push rod 11 to extend, and then the first cover plate 7 and the second cover plate 8 are closed. When the user goes down through the climbing-free device body 5, the second opening sensor 14 controls the electric push rod 11 to work, and then the main controller 6 controls the electric push rod 11 to work. The start sensor 24 monitors the main body 5 of the non-climbing device, and controls the electric push rod 11 to work through the main controller 6, so as to open the first cover plate 7 and the second cover plate 8. When the user and the main body 5 of the non-climbing device pass through the working platform 2, the first cover plate 7 and the second cover plate 8 are closed, so as to facilitate the user's maintenance work. When the first opening sensor 14 or the second opening sensor 24 has a problem, at this time, it can be monitored by the detection opener 12 that the second cover plate 8 is in a stationary state. At this time, the detection opener 12 makes the first pressure switch 22 or the second pressure switch 29 work through the main controller 6. When the main body 5 of the non-climbing device moves upward, when the main body 5 of the non-climbing device conflicts with the first inclined plate 19 at the bottom inclined surface of the first inclined surface receiving block 16, the first inclined plate 19 moves to the first pressure switch 22. One side of the climbing-free device is rotated, and at the same time, the first torsion spring 21 is compressed. The rotating first inclined plate 19 can press down the first pressure switch 22, and the electric push rod 11 is controlled to work through the first pressure switch 22. The first cover plate 7 and the second cover plate 8 are opened through the electric push rod 11. After one end of the climbing-free device body 5 conflicts with the inclined surface of the first inclined surface receiving block 16, the first inclined surface receiving block 16 can slide into the inside of the first receiving groove 15, and the first inclined surface receiving block 16 compresses the first spring 17. When one end of the climbing-free device body 5 no longer conflicts with the first inclined surface receiving block 16, the first inclined surface receiving block 16 is reset under the action of the first spring 17. When the climbing-free device body 5 and the user pass through the working platform 2, the first cover plate 7 and the second cover plate 8 are opened again. When the climbing-free device body 5 is closed again, the climbing-free device body 5 contacts the inclined surface on one side of the bottom end of the second inclined surface receiving block 26, causing the second inclined surface receiving block 26 to move toward the inside of the second receiving groove 25, thereby not touching the second inclined plate 30 and the second pressure switch 29 at one end of the second inclined surface receiving block 26. When the climbing-free device body 5 moves downward, the climbing-free device body 5 contacts the second inclined plate 30 at the inclined surface of the top end of the second inclined surface receiving block 26, and the second pressure switch 29 is pressed downward by the second inclined plate 30, thereby opening the first cover plate 7 and the second cover plate 8, and at the same time, the second inclined surface receiving block 26 slides toward the inside of the second receiving groove 25. When the climbing-free device body 5 and the user pass through the working platform 2, the first cover plate 7 and the second cover plate 8 are closed again, and the climbing-free device body 5 continues to move downward.The main body 5 of the anti-climbing device 10 conflicts with the inclined surface at the top of the first inclined surface receiving block 16, so that the first inclined surface receiving block 16 moves toward the inside of the first receiving groove 15, so as not to touch the first inclined plate 19 and the first pressure switch 22, thereby ensuring that the device is in a normal state. When multiple people need to maintain it, the safety and reliability of the use of the device are further improved by the secondary automatic opening. There is no need to worry that the main body 5 of the anti-climbing device 10 cannot be returned. At the same time, the first cover plate 7 and the second cover plate 8 are in a closed state during the user's maintenance, which meets the requirements of standard specifications. When a problem occurs in the electric push rod 11 or the main controller 6, the user pulls the pull plate 41, and the pull plate 41 drives the slider 37 to slide inside the slide groove 34 through the connecting block 39. The moving slider 37 compresses the third spring 38. At the same time, the slider 37 drives the fixed slide plate 40 to move, and the fixed slide plate 40 slides inside the through groove 36 and the fixed groove 33. When one end of the fixed slide plate 40 is no longer inside the fixed groove 33, At this time, the user can open the second cover plate 8 through the handle 9, and then can pass through the working platform 2. The pull plate 41, the slider 37 and the fixed slide plate 40 can ensure that the user can open the second cover plate 8 at any time, further ensuring the normal use of the device, and will not affect the user's maintenance work. The device can automatically, timely and effectively perform opening and closing work, and will not affect the normal use of the non-climbing device body 5. At the same time, if the device fails, it can also control the electric push rod 11 to work mechanically to ensure the normal opening and closing of the first cover plate 7 and the second cover plate 8. If the electric push rod 11 in the device fails, the user can also open and close the second cover plate 8 mechanically to further ensure the normal use of the device, without worrying that the user cannot open the second cover plate 8 in time and effectively, thereby reducing the user's workload and working time, and then improving the user's work efficiency. At the same time, when multiple people are working, there is no need to worry that the non-climbing device body 5 cannot return.
