[0040] In specific working process, the staff pulls the handle 753, the pulling rope 752 is pulled through the handle 753, in the process, the movable pulley 751 is gradually close to the fixed pulley 41 in the upward direction under the pulling action, the lifting direction of the movable pulley 751 is guided through the limiting between the sliding block 74 and the sliding groove 73, with the upward movement of the movable pulley 751, the adjusting wheel 8 is synchronously moved upward in the lifting frame 7, and since the length of the lifting cable 9 is a fixed value at the moment, the bending curvature of the bending part of the lifting cable 9 gradually decreases in the process that the adjusting wheel 8 moves upward, the bending part of the lifting cable 9 is gradually straightened under the action that the adjusting wheel 8 moves upward, the bottom part moves upward, and in the process of moving upward, the end part of the reinforcement cage 1 is driven to be lifted by the abutting action, so that the reinforcement cage 1 is separated from the cushion block 2, at the same time, with the upward movement of the cross rod 75, the sleeve 754 is synchronously slid upward along the side wall of the inserting rod 421, when the reinforcement cage 1 is at a proper height from the ground under the lifting action of the lifting cable 9, the plug 756 is inserted into the plug hole 755 by the staff, so that the relative position between the sleeve 754 and the inserting rod 421 is fixed, the relative height of the adjusting wheel 8 and the lifting cable 9 is further fixed, and the same principle is used to adjust the movable pulley 751 and the fixed pulley 41 at the other end of the reinforcement cage 1, so that the two ends of the reinforcement cage 1 are lifted from the ground 00.

[0041] As an embodiment of the present application, as shown in Figure 5 、 Figure 7 and Figure 10 , the lower part of the lifting rod 3 is fixedly installed with an isolation frame 37, the isolation frame 37 is horizontally placed in a " " shape structure, and the isolation frame 37 is located above the positioning frame 32, the end part of the isolation frame 37 is installed with a winding shaft 371 through a bearing, the winding shaft 371 is wound with a plastic film 372, the end part of the isolation frame 37 is provided with a long slot 373, the long slot 373 is located below the winding shaft 371, and the exposed end of the plastic film 372 is slid through the long slot 373.

[0042] Specifically, when the height position of the reinforcement cage 1 is adjusted, a gap is formed between the bottom of the reinforcement cage 1 and the ground 00, then the plastic film 372 on the winding shaft 371 is pulled and stretched by the worker to pass through the gap below the reinforcement cage 1, so as to isolate the reinforcement cage 1 from the ground 00, then the spray head 61 is started to spray the rust removal liquid, at the same time, the worker pushes the pull plate 6 to slide on the horizontal cable 5, so as to expand the spraying range of the rust removal liquid, the spraying range of the rust removal liquid can be adjusted by the multiple spray heads 61 and the adjustment of the spraying angle of the spray head 61, so as to improve the efficiency and reduce the invalid loss of the rust removal liquid, in the initial stage of the rust removal liquid spraying, the pull plate 6 is located at one end of the reinforcement cage 1, at this time, the worker controls and adjusts the gap between the movable pulley 751 and the fixed pulley 41 close to this end, so as to sink the end of the reinforcement cage 1 downward, so that the reinforcement cage 1 is placed in an inclined state, then when the worker pushes the pull plate 6 to move and spray the rust removal liquid, part of the rust removal liquid directly drops downward after contacting with the steel bars in the reinforcement cage 1, and part of the rust removal liquid slides along the inclined reinforcement cage 1 under the action of gravity, and then infiltrates into the contact gap between the steel bars in the cage body.

[0043] When the pull plate 6 moves to the other end of the reinforcement cage 1, the worker operates to make the end of the reinforcement cage 1 at this end incline downward, and pushes the pull plate 6 to move back, so as to infiltrate and remove rust on the other side of the steel bar gap, when the rust removal operation completes one reciprocating cycle, the worker adjusts the reinforcement cage 1 to be placed in a horizontal state again, then the worker pulls the traction plate 92 to drive the lifting cable 9 to rotate, and then the reinforcement cage 1 rotates through the abutting and clamping action between the protrusion 91 and the steel bars in the cage body, so as to switch the rust removal operation surface of the reinforcement cage 1, after rotation, the above rust removal operation is repeated to remove rust on the reinforcement cage 1, during the whole rust removal operation, the plastic film 372 is always located below the reinforcement cage 1, so as to collect and collect the rust removal liquid dropped from above, and avoid soil pollution caused by the rust removal operation, with the end of the rust removal operation, the rust removal liquid collected on the plastic film 372 can be collected and treated again, and the used plastic film 372 can be cut off and placed below the reinforcement cage 1 to adapt to the slow dripping process of the rust removal liquid.

[0044] In work:

[0045] The first step: first, the staff will be placed in the vicinity of the reinforcing cage 1 end of the four around the lifting rod 3 and fixed, in the process of placing, positioning ring 33 and the bottom plate 35 can be common to the lifting rod 3 for auxiliary support, so that it remains vertical placement posture, then, through the staff on the length and placement posture of the horizontal cable 5 adjustment, so that it in the reinforcing cage 1 two oblique above the position to keep straight, then, install the pull plate 6, and the loading of the rust removal liquid storage cylinder 62 is placed into the pull plate 6 end of the snap ring, then, debug the nozzle 61, so that the spray angle and spray volume are in the appropriate range.

[0046] The second step: after the position of the lifting rod 3 is locked, the position of the lifting cable 9 is also relatively locked, then, the staff will be in the natural bending state of the lifting cable 9 bending part to push to the bottom of the reinforcing cage 1, then, through the traction plate 92 on both ends of the two lifting cable 9 fixed, so that the overall length of the lifting cable 9 remains fixed.

[0047] The third step: through the staff to pull the handle 753, the movable pulley 751 is gradually close to the fixed pulley 41 in the upper direction under the action of traction, through the limiting between the sliding block 74 and the sliding slot 73, the lifting direction of the movable pulley 751 can be guided, with the upward movement of the movable pulley 751, the adjusting wheel 8 in the lifting frame 7 is synchronized to move upward, and because the length of the lifting cable 9 is fixed at this time, the bending radius of the bending part of the lifting cable 9 gradually decreases during the upward movement of the adjusting wheel 8, and the bending part of the lifting cable 9 is gradually straightened under the action of the upward movement of the adjusting wheel 8, the bottom part is lifted, and in the process of upward movement, the end of the reinforcing cage 1 is lifted by abutting action, so that it is separated from the contact between the cushion 2, then, the staff inserts the plug 756 into the hole 755, further fixes the relative height of the adjusting wheel 8 and the lifting cable 9, and the same principle is used to adjust the group of movable pulleys 751 and fixed pulleys 41 at the other end of the reinforcing cage 1, so that the two ends of the reinforcing cage 1 are lifted off the ground 00.

[0048] The fourth step: after the height of the reinforcing cage 1 is adjusted, there is a gap between the bottom of the reinforcing cage 1 and the ground 00, then, the staff pulls the plastic film 372 on the winding shaft 371 to stretch, so that it passes through the gap below the reinforcing cage 1, so as to realize the isolation between the reinforcing cage 1 and the ground 00, then, start the nozzle 61, and spray the rust removal liquid.

[0049] The fifth step: with the end of the rust removal operation, the rust removal liquid gathered on the plastic film 372 can be collected and treated again, and the used plastic film 372 can be placed under the reinforcing cage 1 by cutting off, so as to adapt to the slow dripping process of the rust removal liquid.
