In addition, please refer to fig. 11, the multifunctional pipe crane with the assembly scissors nippers and the steel die clamps further comprises an infrared remote controller 21 used in cooperation, the infrared remote controller 21 sends an infrared signal to the infrared receiver 10, a controller 22 is arranged in the infrared receiver 10, and the controller 22 controls the rotating motor 3, the rope winder 6, the lifting cylinder 14 and the transverse telescopic cylinder 16 respectively, wherein the infrared remote controller 21 at least comprises a key for sending and controlling the rotating motor 3 to rotate, a key for sending and controlling the rope winder 6 to wind and release the steel rope 9, a key for sending and controlling the lifting cylinder 14 to extend and shorten, and a key for sending and controlling the transverse telescopic cylinder 16 to extend and shorten;

in the above description, when in use, when the whole pipeline crane is required to perform corresponding actions, a worker holds the infrared remote controller 21 and faces the direction in which the infrared receiver 10 receives signals, presses down an instruction for executing corresponding actions on the infrared remote controller 21, and after the pressing, the infrared remote controller 21 sends signals corresponding to the instruction to the infrared receiver 10 and is received by the infrared receiver 10, after the infrared receiver 10 receives the signals, the signals are transmitted to the controller 22, and after the controller 22 receives the corresponding signals, the controller controls the rotating motor 3 or the rope winder 6 or the lifting oil cylinder 14 or the transverse telescopic oil cylinder 16 to perform corresponding actions, so that the whole pipeline crane can be remotely controlled to perform operation, time and labor are saved, and convenience and high speed are achieved.

The working principle of the invention is as follows: when the steel pipe clamp is used, a user controls the rotating motor 3 through the infrared receiver 10 to enable the rotating pipe 2 to rotate and drive the support to rotate to a proper angle, then the steel rope 9 is loosened in a rotating mode through the control rope winder 6, the connecting sleeve head 8 is loosened to a proper angle, the clamp structure 17 is made to be located right above the steel pipe 19, then the lifting oil cylinder 14 is controlled to extend to the position right above the steel pipe 19 to be clamped, then the transverse telescopic oil cylinder 16 is controlled to extend to the positions of two ends of the steel pipe 19, the scissor clamp support 173 is controlled to enable the steel die clamp sleeve 175 to clamp the two ends of the steel pipe 19, then the lifting oil cylinder 14 contracts and controls the rotating motor 3 to rotate to a proper position, the lifting oil cylinder 14 extends, meanwhile, the steel die clamp sleeve 175 is unfolded to complete hoisting of a pipeline, and the steel pipe clamp is convenient to use.

It should be noted that, when the counter weight of loop wheel machine is not enough, the user can put into other counter weights from the one side that spliced pole 121 is close to turning block 1241 to later turn the stopper 1242 again and make the opposite side and the stopper 1242 of stopper 1242 laminate mutually, can satisfy the hoist and mount of heavier pipeline through the increase of counter weight, can prevent through the effect of anticreep subassembly 124 simultaneously that the counter weight from droing, and the effect of use is better.

It should be noted that, in the process of using the crane, the protecting cover 131 can protect the position of the steel rope 9, so as to avoid the accident injury of the person, and the position of the steel rope 9 can be limited by the limiting ring 1342, so as to avoid the possible fracture of the steel rope 9 and hurt the person, and the safety effect is good.

It should be noted that, the user can control the scissors clamp support 173 through the infrared receiver 10 to complete the closing operation, and the four sets of steel mold clamp sleeves 175 can clamp two ends of the steel pipe 19 respectively in pairs, so as to clamp the steel pipe 19, and in the clamping and transporting process, the anti-slip sleeve 1763 can prevent the pipeline from falling off, so that the use effect is good.
