[0026] The surface of the squeezing plate 401 is rough, thereby increasing friction, so that the squeezing plate 401 can better clamp the welding machine or the tool box.

[0028] The working steps of the above embodiment are: first, the staff fixes the sliding guide rail 2 by clamping the protective clamping hand 202 on the beam above the pipe gallery, thereby installing the present invention in the pipe gallery. When cracks or leaks occur in the pipe gallery, the staff is required to repair the cracks or leaks in the pipe gallery, and then the maintenance personnel control the electric drive wheel of the peripheral device to push the construction platform 1 and all the parts connected to it to move left and right on the sliding guide rail 2, so that the construction platform 1 moves in the pipe gallery; when the construction platform 1 moves to the top of the crack or leak of the pipe, the maintenance personnel control the electric drive wheel of the peripheral device to stop rotating; then the maintenance personnel sequentially Push the two limit plates Ⅰ9 to move back to back, so that the limit block Ⅰ8 is disengaged from the limit groove on the limit plate Ⅰ9, and the round hole on the limit plate Ⅰ9 is aligned with the limit block Ⅰ8, and then stop pushing the limit plate Ⅰ9. At this time, the limit plate Ⅰ9 no longer limits the limit block Ⅰ8, and then the maintenance personnel pushes the rotating plate 6 to rotate clockwise from a left perspective. When the rotating plate 6 rotates to fit the bottom surface of the construction platform 1, the maintenance personnel stops rotating the rotating plate 6, and then the maintenance personnel places the electric welder or tool box needed for repair on the descending platform 3. In the process of placing the electric welder or tool box, the maintenance personnel puts one end of the electric welder or tool box against the extrusion plate 40 1, and then push the electric welder or tool box backward to compress the spring telescopic rod I 402. Then, when the electric welder or tool box is completely moved to the rear of the protrusion 3001, the electric welder or tool box is pressed between the extrusion plate 401 and the protrusion 3001. Then, the electric welder or tool box is clamped between the extrusion plate 401 and the protrusion 3001 by the resetting elastic force of the spring telescopic rod I 402, so that when the descending platform 3 moves downward, the electric welder or tool box will not shake and fall. During the descent process, the maintenance personnel do not need to additionally fix the electric welder or tool box, thereby improving safety. Then The maintenance personnel moves to the descending platform 3, then pulls the rotating plate 6 to rotate upward and reset. After the rotating plate 6 rotates to fit with the limit strip 5, the limit block Ⅰ8 will be aligned with the limit plate Ⅰ9 again. Then the staff pushes the two limit plates Ⅰ9 to move toward each other in turn, so that the round hole on the limit plate Ⅰ9 is misaligned with the limit block Ⅰ8, so that the limit block Ⅰ8 enters the limit groove of the limit plate Ⅰ9, thereby limiting the limit block Ⅰ8 and the rotating plate 6, so that the rotating plate 6 remains vertical to the descending platform 3, and the maintenance personnel are protected by the protective plate 4, the rotating plate 6 and the protective rope 7 to prevent them from accidentally falling from the descending platform 3.

[0029] The maintenance personnel push the limit plate II 112 to move backward, so that the round hole on the limit plate II 112 is aligned with the limit block II 111, and the limit plate II 112 no longer limits the limit block II 111, so that the lowering platform 3 can move downward. Then the maintenance personnel control the motor 103 to rotate through the remote control, and the motor 103 drives the winding wheel 101 to rotate, loosening the suspension rope 102, and the lowering platform 3 begins to move downward under the influence of gravity. In the process of the lowering platform 3 moving downward, when the maintenance personnel visually observe that the lower side of the lowering platform 3 is aligned with the upper side of the cross bar under the pipe gallery, it is as shown in the figure. Fig.10In the state shown, the control motor 103 stops rotating, and then the maintenance personnel presses down the sliding rod 304 to loosen the connecting rope 303, so that the subsequent connecting rope 303 will not pull the limit plate III 302, and then the maintenance personnel pushes every two adjacent push rods 305 to move backwards by their feet, and the push rods 305 drive the sliding plate 301 and all the parts connected to it to move backwards, so that the push rods 305 extend out of the descending platform 3. Since the torsion spring between the limit plate III 302 and the sliding plate 301 is in a compressed state in the initial state, when the limit plate III 302 moves to the outside of the descending platform 3, the torsion spring between the limit plate III 302 and the sliding plate 301 will The limit plate Ⅲ302 is driven to rotate downward, so that the limit plate Ⅲ302 and the sliding plate 301 are in a vertical state. When the limit plate Ⅲ302 contacts the beam under the pipe gallery during movement, the beam will squeeze the limit plate Ⅲ302, so that the limit plate Ⅲ302 rotates upward, and the torsion spring between the limit plate Ⅲ302 and the sliding plate 301 is compressed again. Then, when the limit plate Ⅲ302 passes over the beam, the limit plate Ⅲ302 is no longer squeezed by the beam. Then, the torsion spring between the limit plate Ⅲ302 and the sliding plate 301 drives the limit plate Ⅲ302 to rotate downward, and the limit plate Ⅲ302 rotates again to a state perpendicular to the sliding plate 301. The maintenance personnel then pull all the push rods 301 respectively. 5 moves towards each other for a distance, so that the limit plate III 302 moves towards the direction of the beam under the pipe gallery again. When the limit plate III 302 is in contact with the beam, the limit plate III 302 and the sliding plate 301 cannot move further. At this time, the maintenance personnel stop pushing the pushing rod 305, so as to limit the sliding plate 301 and the limit plate III 302 through the beam under the pipe gallery, and the sliding plate 301 is overlapped on the beam. At this time, the descending platform 3 is supported by the two adjacent beams. Then the maintenance personnel pushes the pushing rod 305 downward again, so that the pushing rod 305 is inserted into the circular hole of the descending platform 3, so as to lock the sliding of the sliding plate 301, so that the sliding plate 301 and the descending platform The descending platform 3 will be unable to move, and the sliding plate 301 and the limiting plate III 302 will limit the descending platform 3, so that the subsequent descending platform 3 will not shake, and the sliding plate 301 will be placed on the beam under the pipe gallery, so as to support the descending platform 3, improve the stability of the descending platform 3, and further improve the safety of maintenance personnel performing maintenance work on the descending platform 3; then the maintenance personnel can repair the cracks or leaks of the pipeline on the descending platform 3; thereby avoiding the problem that when the cracks or leaks of the pipeline are located between the large-spacing beams of the pipe gallery, there is no position between the beams to support the maintenance personnel, and it is difficult to repair the pipeline located between the beams of the pipe gallery.

[0030] After the maintenance personnel have completed the repair work on the crack or leakage of the pipeline, they first pull the push rod 305 out of the round hole of the descending platform 3, and then push each two corresponding push rods 305 on the left and right to move back to each other. Then, after moving a short distance, when there is enough space between the limit plate III 302 and the beam under the pipe gallery to allow the limit plate III 302 to rotate upward, the maintenance personnel stop pushing the push rod 305, and then pull the sliding rod 304 to move upward. The sliding rod 304 pulls the connecting rope 303, so that the connecting rope 303 pulls the limit plate III 302 to rotate upward and reset, so that the limit plate III 302 rotates to fit the sliding plate 301. Since the sliding rod 304 and the sliding plate 301 are connected by a damping sliding connection, and the damping force is greater than the elastic force of the torsion spring between the sliding plate 301 and the limit plate III 302, the limit plate III 302 will remain in a state of fitting with the sliding plate 301, which is convenient for the sliding plate 30 1 is reset; then the maintenance personnel pushes all the pushing rods 305 to move toward each other, thereby driving the sliding plate 301 to reset. When the sliding plate 301 is reset, the maintenance personnel controls the motor 103 through the remote control to drive the winding wheel 101 to reverse, thereby pulling the descending platform 3 and all the parts connected thereto to move upward and reset. When the descending platform 3 moves upward to fit with the construction platform 1, the reset is completed. At this time, the limit block Ⅱ111 will move again to align with the limit plate Ⅱ112. Then the maintenance personnel push the four limit plates Ⅱ112 forward in turn, so that the round hole of the limit plate Ⅱ112 is misaligned with the limit block Ⅱ111, so that the limit block Ⅱ111 and the descending platform 3 are limited by the limit groove of the limit plate Ⅱ112, and then the descending platform 3 is locked on the construction platform 1, and there is no need to suspend the descending platform 3 for a long time by the lifting rope 102, so as to avoid the problem of accelerated aging caused by the lifting rope 102 being subjected to force for a long time.

[0031] The maintenance personnel controls the electric drive wheel of the peripheral device to drive the construction platform 1 to move to the next crack or leak of the pipeline, so as to repair the next crack or leak. When all cracks or leaks on the pipeline are repaired, the staff transfers the electric welding machine or tool box from the descending platform 3 to the construction platform 1, and then the staff pushes the protective plate 4 and the rotating plate 6 to rotate towards each other, and the rotating plate 6 will drive the limit bar 5 to rotate together, and in the process of rotation, the protective plate 4 will squeeze the squeezing rod 412, so that the squeezing rod 412 moves downward, and the spring telescopic rod II 411 is compressed. When the protective plate 4 and the rotating plate 6 are aligned, the two matching plates 414 will be aligned at this time, and then the maintenance personnel push the latch 413 to Move in the direction close to the rotating plate 6, so that the pin 413 is inserted into the matching plate 414 on the rotating plate 6, and the protective plate 4 and the rotating plate 6 are locked, so that the protective plate 4 and the rotating plate 6 cannot be reset and rotated, and the spring telescopic rod II 411 will not be able to push the protective plate 4 and the rotating plate 6 to rotate. The protective plate 4 and the rotating plate 6 maintain a horizontally aligned state, so that the lowering platform 3 is shielded by the protective plate 4 and the rotating plate 6, and the upper side of the lowering platform 3 is prevented from being exposed to the environment for a long time, causing rain, dust and other impurities to fall on the lowering platform 3, affecting the cleanliness of the working environment on the upper side of the lowering platform 3, and avoiding the accumulation of a large amount of solid impurities in the external environment on the lowering platform 3, affecting the safety of the next operation.

[0032] It should be noted that when a worker stands on the construction platform 1, the construction platform 1 and the sliding guide rail 2 will move downward, and the protective clamping hand 202 cannot move because it clamps the crossbeam above the pipe gallery. Therefore, after the construction platform 1 and the sliding guide rail 2 move downward, the protective clamping hand 202 will clamp tighter, thereby improving the safety of the workers on the construction platform 1, and by adding a protective rod 211, the protective rod 211 can prevent the construction platform 1 from passing through the pipe gallery, so that in the event of an accidental fall, the protective rod 211 can be blocked from falling through the pipe gallery frame, and the pipe gallery frame can be used to prevent the protective rod 211 from falling. The protection rod 211 is supported to provide emergency support for the construction platform 1 to prevent it from falling further downward, further increasing the safety of the present invention. Before controlling the movement of the construction platform 1, the maintenance personnel can pull out the plug rod of the construction platform 1 so that the protection rod 211 is no longer limited by rotation, and then rotate the protection rod 211 in the direction close to the construction platform 1 to avoid the protection clamp 202. During maintenance, the protection rod 211 can be rotated and reset, and then the plug rod in the protection rod 211 can be reinserted, so that the protection rod 211 cannot rotate, thereby restoring the protection capability of the construction platform 1.

[0033] Example 2 On the basis of Example 1, Figure 6As shown, it also includes an electric drive reel 501; the descending platform 3 is fixedly connected to the electric drive reel 501, and a safety rope is wound inside the electric drive reel 501, and a lock is connected to the free end of the safety rope. The electric drive reel 501 is driven to rotate by the motor inside it, and the safety rope inside the electric drive reel 501 prevents maintenance personnel from falling off the descending platform 3.

[0034] It also includes a rotating rod 511; the left and right sides of the descending platform 3 are both rotatably connected with the rotating rod 511.

[0035] The working steps of the above embodiment are: when repairing cracks or leaks in the pipeline, the maintenance personnel need to stick their hands or part of their body out from above the protective plate 4, the rotating plate 6 and the protective rope 7 to perform the repair, which makes it possible for the maintenance personnel to fall out of the descending platform 3. Therefore, before the maintenance personnel perform the repair, the maintenance personnel pull out the safety rope in the electric drive reel 501 and tie it to their body, and then perform the repair work on the pipeline. When the maintenance personnel accidentally falls out of the descending platform 3, the safety rope will squeeze the left or right protective rope 7, so that all the protective ropes 7 are instantly bent downward, so that the safety rope is fitted with the left or right side of the descending platform 3, and at the moment the maintenance personnel falls out, due to the locking effect of the internal motor, the electric drive reel 501 is prevented from happening. When the maintenance personnel is lifted up, the electric drive reel 501 will tighten the safety rope to hold the maintenance personnel and prevent them from falling further. Then the maintenance personnel will control the electric drive reel 501 to rotate and start to reel in the safety rope, thereby pulling the maintenance personnel upward, making it easier for the maintenance personnel to climb back onto the descending platform 3, so as to protect the maintenance personnel and improve the safety of the maintenance personnel in performing repair work. Moreover, through the rotating rod 511 arranged on the descending platform 3, after the maintenance personnel falls out from the left or right side of the descending platform 3, the electric drive reel 501 will reel in the safety rope to pull the maintenance personnel upward. In the process, the rotating rod 511 can reduce the friction between the safety rope and the descending platform 3, making it easier for the electric drive reel 501 to pull the maintenance personnel up through the safety rope.
