Working principle: when the self-locking anti-falling lifting appliance for pipelines and the wind pressure-resistant bracket thereof are used, firstly, as shown in figures 1-3, the distance between adjacent bottom brackets 1 is changed according to the different diameters of the cross-section sizes of the pipelines, the rotary motion of the electric rotary seat 5 externally connected with electric equipment is used for enabling the rotary seat 5 to be meshed with the bevel teeth at the end part of the screw rod body 4, the purposes of the rotary motion of the screw rod body 4 and the threaded connection of the screw rod body 1 are achieved, under the action of the joint sliding connection between the bottom brackets 1 and the end part of the connecting frame 3, the bottom brackets 1 move away from the connecting frame 3, the distance between the bottom brackets 1 is changed, two groups of lifting appliances are simultaneously used, the pipelines are put between the side brackets 2, the gravity of the pipelines is used for pressing the bearing frame 8 to enable the positioning sleeve 6 to slide downwards on the side brackets 2 along with the downward sliding of the positioning sleeve 6, the gear shaft 11 and the bar-shaped saw tooth structure on the side bracket 2 are meshed with each other, so that the gear shaft 11 drives the limit frame 9 to perform overturning motion, the effect of positioning the pipeline is achieved under the self gravity action of the limit frame 9 and the bearing frame 8 by utilizing the interaction of the limit frame 9 and the bearing frame 8, meanwhile, as shown in figure 2, when the positioning sleeve 6 moves downwards, the limit piece 14 rotates and leads the elastic rubber head 15 to deform, the tail end of the limit piece 14 can be led into different positioning grooves 12 without influencing the downward movement of the positioning sleeve 6, when the positioning sleeve 6 has upward movement trend, the tail end of the limit piece 14 can be clamped in the positioning grooves 12, the movement of the positioning sleeve 6 can be performed only by rotating the dismounting bolt body 13 to change the tail end position of the limit piece 14, so that the combined action of the bearing frame 8 and the limit frame 9 clamps the pipeline more stably, instability and looseness after positioning and installation can not occur;
and as shown in fig. 1 and fig. 4-5, when the pipe continuously moves downwards to press to the top of the rubber seat 20, the external force of the telescopic airbag body 19 and the second elastic piece 21 under the rubber seat 20 can be weakened when the pipe moves downwards, the protection effect of the lifting appliance is achieved, and as the rubber seat 20 and the pipe move downwards, the rubber seat 20 deforms and the pipe are more attached, the gas inside the telescopic airbag body 19 is led into the inner cavity 18, the pressure inside the inner cavity 18 is increased, the movable frame 24 is pushed to move by the pressure, the third elastic piece 26 deforms, the end of the movable frame 24 does not plug the pipe end of the threaded hose 27 after moving, the gas inside the telescopic airbag body 19 and the inner cavity 18 is led into the airbag cavity 16 through the threaded hose 27, the airbag inside the airbag cavity 16 deforms, the elastic friction pad 17 on the air bag is more attached to the outer wall of the pipeline, so that the attachment and positioning of the pipeline are realized, the contact friction force of the pipeline is increased, the pipeline is more stable during subsequent lifting, the suction positioning under the negative pressure action can be generated at the bottom of the pipeline by the elastic action of the second elastic piece 21 and the telescopic air bag body 19, the shape of the movable frame 24 and the elastic action of the third elastic piece 26, after the gas in the telescopic air bag body 19 is led into the air bag cavity 16, the gas in the air bag cavity 16 cannot flow back into the telescopic air bag body 19 through the threaded hose 27 due to the limiting action of the movable frame 24, the air pressure in the air bag cavity 16 also pushes the movable frame 24 to enable the positioning to be more stable, and the gas backflow from the air bag cavity 16 to the inside of the telescopic air bag body 19 can be caused only by the external pulling of the pull ring 25, the operation is convenient and quick;
according to the lengths of the pipelines shown in fig. 1 and 6-7, after the two groups of lifting devices move and adjust to clamp and position the pipelines, the superposition total length of the multi-section telescopic rod 30 is changed, the positions of the two groups of lifting devices are positioned to form a stable triangular structure as shown in fig. 7, the clamping and stabilizing effect of the lifting devices on the pipelines is improved, the pipelines and the multi-section telescopic rod 30 are kept in a mutually parallel state, when the lifting rope 28 is subjected to external force such as external wind pressure, the X-shaped in the wind-resistant frame body 29 rotates due to pulling by the external force of the lifting rope 28, and the buffer effect of the lifting rope 28 is achieved by utilizing the homopolar magnetic repulsion effect of the permanent magnet 32 at the end part of the wind-resistant frame body 29, so that the compression-resistant protection effect of the lifting rope 28 and the wind-resistant frame body 29 on the external force such as wind pressure is realized, the pipelines are more stable in subsequent lifting and conveying, and the use safety protection effect is good.
Although the present invention has been described with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements and changes may be made without departing from the spirit and principles of the present invention.
