Example two
As shown in fig. 6, in comparative example one, another embodiment of the present invention is: the shower nozzle 7 includes three ventholes, the bottom fixed mounting of shower nozzle 7 has upper plate 22, the bottom of upper plate 22 is provided with hypoplastron 23, rotate on the top surface of running through upper plate 22 and be connected with two symmetries and be provided with handle 24, the bottom fixed mounting of handle 24 has the threaded rod, the threaded rod runs through the top surface of hypoplastron 23 and with hypoplastron 23 threaded connection, during operation, cooperation shower nozzle 7's structure setting lets the air current outwards spun area bigger, have more even power to guarantee the stable process of rectifying of decking, and upper plate 22 and hypoplastron 23 are used for blocking the decking, through rotatory handle 24 and threaded rod, let hypoplastron 23 rise, thereby clip the decking, guarantee the stable installation process and the convenient process of unloading of shower nozzle 7.
When the invention works, the prefabricated bridge deck is fixed by the connecting rope 4, a plurality of spray heads 7 are fixed with the top surface of the bridge deck, when the gantry crane 1 moves with the bridge deck, the lower bridge deck can swing to the position under the action of the tensile force due to the longer length of the drooping chain 8, so that the lower bridge deck can swing continuously under the action of the tensile force, the subsequent alignment process is inconvenient, the working efficiency is lower, workers are easy to be accidentally injured, through the arrangement of the spray heads 7 and the spray assemblies, when the bridge deck follows the swing process of the gantry crane, the spray assemblies are started to spray air flow from the spray heads 7 and face towards the swing direction, so that part of inertia of the bridge deck is counteracted, and after the bridge deck moves to the position right below the output end of the gantry crane 1, the swing is stopped, thereby not only facilitating the positioning process, reducing the time required for waiting for the inertia consumption, but also reducing the situation of accidentally injuring operators; when the bridge deck is fixed, four lifting hooks 5 penetrate through reserved holes at four corners on the top surface of the prefabricated bridge deck, after penetrating, the lifting hooks 5 are wound on from the bottom and clamp the connecting ropes 4, so that the effect of stably grabbing the bridge deck is ensured, the operation is simple, the structure is not complex, when the four connecting ropes 4 are fixed, the four spray heads 7 are fixed at the middle positions of the four sides of the bridge deck, and as the gantry crane 1 can only move in four directions of front, back, left and right on the horizontal plane, the four spray heads 7 just can move in the corresponding four directions, and the air injection process of the spray heads 7 is convenient to operate; when the gantry crane 1 drives the connecting seat 3 to move, the hanging plate 2 below does not move immediately, so that a deflection angle is generated between the sagging chain 8 and the connecting seat 3, the spherical balls 10 rotate in cooperation with the arrangement of the spherical balls 10, the shearing force between the sagging chain 8 and the connecting seat 3 can be reduced instead of the deflection angle, the service life of the sagging chain 8 is prolonged, the spherical balls 10 can only turn in four directions due to the arrangement of the four extension rods 13, and when the swinging direction of the sagging chain 8 changes due to external influence, the resistance to be overcome when the sagging chain 8 swings in other directions is larger due to the fact that the spherical balls 10 cannot rotate at the moment, so that the irregular swinging effect of the sagging chain 8 caused by external factors can be reduced; when the air pump device works, the air pump 11 is fixedly connected to the connecting seat 3, and then the spray head 7 is connected with the air pump 11 through the air flow pipe 9, so that the air pump 11 can be large, enough air flow driving force is ensured, and meanwhile, the air pump device is arranged in a separated mode, so that the weight of the air pump 11 is not clamped at the hanging plate 2, and the problem of inertia force increase is solved; when the connecting seat 3 moves to enable the hanging plate 2 and the bridge deck below to start swinging, the ball 10 rotates at the moment, so that the extension rod 13 on the same side with the swinging direction is pressed down to drive the clamping rod 15 to slide down and press the blocking disc 17 from the original inclined state to the horizontal state, meanwhile, as the blocking disc 17 is horizontal, the pressing button 18 is not pressed any more, the corresponding air pump 11 starts to work when the pressing button 18 is released, when the pressing button 18 is pressed down, the air pump 11 stops working, and as the swing amplitude of the ball 10 is larger, the blocking disc 17 is pressed more horizontally; the blocking disc 17 can only rotate to a horizontal state at most and cannot rotate reversely; when the air flow output effect is blocked at the minimum level, as the angle between the sagging chain 8 and the connecting seat 3 is smaller, the deviation between the ball 10 and the extension rod 13 is smaller, the extension rod 13 can pull the clamping rod 15 back, so that the blocking disc 17 blocks more space of the column fixing pipe 16, through the arrangement, the effect that the air pump 11 at the corresponding side is automatically opened when the sagging chain 8 swings is realized, the spray head 7 starts to spray air is realized, the manual operation is not needed, and meanwhile, as the sagging chain 8 tends to be vertical, the air flow is smaller, and the sagging chain 8 returns to the vertical state in a more stable state; when the device works, the blocking disc 17 is arranged in a light-weight mode at one side, so that the blocking disc 17 is always in a closed state at the beginning, meanwhile, the magnet material enables the blocking disc 17 to have larger force to press the pressing button 18 at the beginning, meanwhile, after the extension rod 13 returns to the horizontal state, the blocking disc 17 is not extruded any more, and at the moment, the blocking disc 17 can be rotated to the closed state under the action of gravity and wind force, so that the reusable effect is realized; when the clamping rod 15 and the blocking disc 17 are extruded, the clamping rod 15 can be jacked into the clamping groove 19 and clamped with the convex block 20, so that when the clamping rod 15 can ascend and return, one end of the blocking disc 17 is driven to ascend, the convex block 20 is triggered to be recovered by the final power component, the clamping rod 15 can be separated, and the blocking disc 17 is in an inclined state in the final stage and can be matched with wind power to incline, the blocking disc 17 has enough force to press the pressing button 18, the air pump 11 is closed, and meanwhile, the clamping rod 15 can also have enough force to control the blocking disc 17 to move; when the clamping rod 15 returns to drive one end of the blocking disc 17 to tilt upwards, so that when the lower pressing block 26 extrudes to the inner wall of the fixed pipe 16, the liquid in the pressure groove extrudes the sealing block 21 to slide downwards due to sinking of the lower pressing block 26, the lug 20 is pulled back to the original position by being matched with pulling of the moving rope, and the sealing block 21 has enough power to pull the lug 20 back due to the fact that the pressure groove is wide in upper part and narrow in lower part, and then the end of the blocking disc 17 always clings to the fixed pipe 16 to wait for the next operation under the adsorption effect of the magnet.
