[0001] The present invention relates to the technical field of construction scaffolds, and particularly to a construction scaffold for on-site anti-corrosion operation of lock gates. Background Art

[0002] With the development of society, as a core facility to ensure the navigation safety of the Yangtze River waterway, the miter gates of locks play an important role in regulating water levels and guiding ships to pass. Their metal structures are long-term affected by water flow impact, water vapor erosion, etc., and anti-corrosion maintenance is crucial. At present, for anti-corrosion construction of miter gates, a construction platform needs to be built on-site, and painting operations are carried out after being fixed by a construction scaffold.

[0003] In the existing construction methods, there are significant defects when the construction scaffold fixes the miter gate: traditional fixing methods mostly rely on temporary welding or simple bolt connections. For the complex grillage structure and flat plate surface of the gate, the fixing operation is cumbersome and time-consuming, and it is difficult to complete the erection within the limited navigation stoppage and maintenance period; at the same time, insufficient fixing stability may cause the construction scaffold to shake, affecting the painting accuracy and even leading to safety accidents, and repeated disassembly is likely to cause damage to the gate surface, increasing the subsequent maintenance cost. Summary of the Invention

[0015] The present invention provides a construction scaffold for on-site anti-corrosion operation of a lock gate. It has the following beneficial effects:

[0016] 1. By setting the beam grid surface fixing mechanism, during use, rotate the bidirectional lead screw to drive the moving block to move towards each other along the sliding rod, so that the clamping block clamps the beam grid. At the same time, the spring inside the connecting rod is compressed to provide a continuous thrust.

[0017] 2. By setting the flat surface fixing mechanism, during use, rotate the second turning handle to drive the worm to rotate. The worm meshes with the worm wheel to make the rotating magnet rotate, changing the magnetic field direction between it and the fixed magnet to form a closed magnetic line. The mounting box is adsorbed on the flat plate through the magnetic force, realizing the rapid fixation of the flat surface by the magnetic force. There is no need for hard connections such as bolts. The operation is simple and the fixation is firm, avoiding the damage to the gate surface caused by traditional bolt fixation. At the same time, it can be quickly disassembled to meet the rapid assembly requirements of the construction platform.

[0018] 3. By setting up the connecting component, during use, after inserting the bolt into the socket, rotate the driving rod with a cross screwdriver. Through the external thread, the fixing pin is inserted into the opening hole, and the upper and lower vertical rods are fixedly connected by cooperating with the flange and bolts. The quick and precise connection of the upper and lower construction frames is achieved through the mechanical locking structure. The positioning pin and the bolt cooperate to ensure the connection strength and stability, avoiding the shaking problem of the traditional connection method. At the same time, the construction process is simplified and the erection time of the construction platform is shortened. BRIEF DESCRIPTION OF THE DRAWINGS

The bidirectional lead screw 402 is movably installed inside the mounting block 401. The two ends of the bidirectional lead screw 402 are respectively left-handed and right-handed threads, which are used to synchronously drive the moving blocks 404 on both sides. The slide bar 403 is fixedly installed inside the mounting block 401, providing a non-rotating linear guide for the moving block 404. On both sides of the outer wall of each mounting block 401, a moving block 404 is movably installed. The moving block 404 is internally provided with screw holes and slide holes corresponding to the bidirectional lead screw 402 and the slide bar 403. The clamping block 405 is movably installed on the outer wall of the moving block 404. The clamping block 405 is made of rubber to avoid damaging the anti-corrosion layer on the surface of the grillage 101. The two clamping blocks 405 are attached to both sides of the grillage 101. The moving block 404 is internally provided with screw holes and slide holes corresponding to the bidirectional lead screw 402 and the slide bar 403, ensuring that the moving block 404 moves towards or away from each other along the rotation direction of the bidirectional lead screw 402.

[0037] In the embodiment, as Figures 5 to 9As shown in the figure, the beam grid surface fixing mechanism 4 further includes a connecting frame 406, a connecting rod 407, a telescopic rod 408, a slider 409, a chute 410 and a spring 411. A connecting frame 406 is movably installed between the moving block 404 and the clamping block 405. The connecting frame 406 is inclined and forms an angle of 45° with the horizontal plane.

A telescopic rod 408 is slidably installed inside the connecting rod 407 and can be telescoped along the axis of the connecting rod 407. The outer wall of the telescopic rod 408 is fixedly connected with a slider 409. A chute 410 is opened at one end of the moving block 404 close to the clamping block 405. The slider 409 is slidably installed inside the chute 410 to limit the movement track of the clamping block 405. A spring 411 is fixedly installed inside the connecting rod 407.

The mounting boxes 501 of multiple flat surface fixing mechanisms 5 are dispersedly fixed on one side of the front frame body 202 close to the gate body 1. Each mounting box 501 is attached to the flat plate 102, and a rubber pad is provided on the contact surface to enhance the sealing performance and anti-slip performance. Two fixed magnets 502 are fixedly installed inside the mounting box 501. A rotating magnet 503 is movably installed inside the mounting box 501. Neodymium iron boron permanent magnetic material is used to provide a constant magnetic field. The rotating magnet 503 is located between the two fixed magnets 502. The magnetic fields between the two fixed magnets 502 and the rotating magnet 503 interact to form a closed magnetic line of force 504. The adsorption force is realized through the magnetic field closing principle. The magnetic line of force 504 starts from the N pole of one fixed magnet 502, passes through the rotating magnet 503 and then returns to the S pole of the other fixed magnet 502 to form a continuous magnetic field loop. The magnetic field intensity can be adjusted by the angle of the rotating magnet 503.

[0039] The flat surface fixing mechanism 5 in the embodiment further includes a worm gear 505 and a worm 506. The worm gear 505 is fixedly connected to the bottom of the rotating magnet 503 and is coaxially fixed with the rotating magnet 503. The worm 506 is movably installed at the bottom of the mounting box 501. The axis of the worm 506 is perpendicular to the axis of the worm gear 505, forming a 90° transmission. The worm gear 505 and the worm 506 are meshed with each other to ensure the slow and stable rotation of the rotating magnet 503.

[0040] In the embodiment, as Figures 13 to 15 shown, the connection component 3 includes a flange 301, a bolt 302, a plug pin 303 and a jack hole 304. Flanges 301 are fixedly connected to both the upper and lower ends of the vertical rod 203. Bolts 302 are fixedly installed between the two flanges 301. Four bolts 302 are used for each group of flanges 301 and are tightened in the diagonal order. The plug pin 303 is fixedly connected to the bottom of the vertical rod 203, and the jack hole 304 is formed at the top of the vertical rod 203. The plug pin 303 is located inside the jack hole 304. The connection component 3 further includes a mounting groove 305, a fixing pin 306, an opening 307, a driving rod 308, an external thread 309 and a cross slot 310. The mounting groove 305 is formed inside the plug pin 303. The fixing pin 306 is slidably installed inside the mounting groove 305. Two openings 307 are formed inside the vertical rod 203, and the openings 307 communicate with the jack hole 304. The fixing pin 306 is located inside the front opening 307. The driving rod 308 is movably installed inside the mounting groove 305. An external thread 309 is formed at the front end of the outer wall of the driving rod 308. A screw hole corresponding to the external thread 309 is formed inside the fixing pin 306. The cross slot 310 is formed at the rear end of the driving rod 308, and the position of the cross slot 310 corresponds to that of the rear opening 307.

[0041] Working principle: First, hoist the rear frame body 201 and the front frame body 202 of the bottom section construction scaffold 2 to the foundation around the ship lock miter gate body 1, so that the rear frame body 201 is aligned with the grillage 101 at the rear end of the gate, and the front frame body 202 is aligned with the flat panel 102 at the front end.

[0042] Rotate the handle 412 of the rotating grillage surface fixing mechanism 4 to drive the bidirectional lead screw 402 to rotate, drive the two moving blocks 404 to move towards each other along the slide rod 403, and push the clamping block 405 to clamp the grillage 101 through the connecting frame 406. At this time, the spring 411 inside the connecting rod 407 is compressed to provide a continuous clamping force. The inclined design of the connecting frame 406 utilizes the reverse friction force to enhance the stability and ensure that the rear frame body 201 is firmly fixed on the grillage 101.

[0043] Rotate the handle 507 of the rotating flat surface fixing mechanism 5. Through the meshing of the worm 506 and the worm gear 505, drive the rotating magnet 503 to rotate, so that a closed magnetic line 504 is formed with the fixed magnet 502, and adsorb and fix the mounting box 501 of the front frame body 202 on the flat panel 102.

[0044] After the bottom-section construction scaffold 2 is fixedly completed, hoist the upper-section construction scaffold 2, align the latch 303 of the upper-layer vertical rod 203 with the socket 304 of the lower-layer vertical rod 203 and insert it to complete the preliminary positioning. Insert a cross screwdriver into the cross slot 310 of the driving rod 308, rotate the driving rod 308, push the fixing pin 306 forward through the external thread 309 and insert it into the opening 307 of the vertical rod 203. At the same time, fix the flanges 301 of the upper and lower-layer vertical rods 203 with bolts 302 to achieve the vertical connection and locking of the upper and lower-layer construction scaffolds 2.

[0045] According to the above steps, hoist the construction scaffold 2 layer by layer, and successively complete the fixation of each layer of the construction scaffold 2 to the gate grid 101 and the flat plate 102 and the connection between the upper and lower layers.
