The rotary lifting mechanism 5 comprises a driving motor 51, a driving shaft 52, a driving bevel gear 53, a lifting rod 54, a lifting bevel gear 55, a lifting block 56, a driven shaft 57, a first bevel gear 58, a second bevel gear 59, a rotary bevel gear 510 and a rotating shaft 511, wherein the driving motor 51 is fixedly arranged on the outer side wall of the base 1 through a motor base, the output end of the driving motor 51 is connected with the driving shaft 52 through a coupler, the driving shaft 52 is arranged in an installation groove of the base 1 through a bearing, the driving bevel gear 53 is sleeved at the other end of the driving shaft 52, the driving bevel gear 53 is meshed and connected with the lifting bevel gear 55, the lifting bevel gear 55 is sleeved at the lower end of the lifting rod 54, an external thread is arranged on the outer side wall of the lifting rod 54, the lifting rod 54 is in threaded connection; the driven shaft 57 is installed in the installation groove of the base 1 through a bearing, a first bevel gear 58 and a second bevel gear 59 are respectively sleeved at two ends of the driven shaft 57, the first bevel gear 58 is meshed with the lifting bevel gear 55, the second bevel gear 59 is meshed with the rotating bevel gear 510, the rotating bevel gear 510 is sleeved at one end of the rotating shaft 511, the other end of the rotating shaft 511 is fixed on the lower end face of the clamping frame 63, and the rotating shaft 511 is coaxial with the clamping frame 63.

When the pipeline clamping device works specifically, the driving motor 51 is started, the driving motor 51 drives the driving shaft 52 to rotate through the coupler, the driving shaft 52 drives the driving bevel gear 53 fixedly sleeved on the outer wall of the driving shaft 52, the driving bevel gear 53 drives the lifting bevel gear 55 to rotate through gear meshing transmission, the lifting bevel gear 55 drives the first bevel gear 58 to rotate, the first bevel gear 58 is fixedly sleeved at one end of the driven shaft 57, the second bevel gear 59 is sleeved at the other end of the driven shaft 57, the second bevel gear 59 rotates the second bevel gear 59, the second bevel gear 59 drives the rotating bevel gear 510 to rotate, the rotating bevel gear 510 is fixedly sleeved on the rotating shaft 511, and the rotating shaft 511 and the clamping frame 63 are coaxially fixed, so that the clamping frame 63 rotates through; simultaneously, the lifting bevel gear 55 is fixedly sleeved at the lower end of the lifting rod 54 to drive the lifting rod 54 to rotate, the lifting rod 54 is sleeved with a lifting block 56 through threaded connection, the lifting block 56 is further driven to move on the lifting rod 54, the lifting block 56 is connected with the locking mechanism 7 through the connecting block 3, the locking mechanism 7 drives the rubber heat-insulating sleeve to move downwards, and the rubber heat-insulating sleeve is further sleeved on the outer side wall of the pipeline.

2 spouts of crane are T type spout, be provided with T type slider on 56 both sides walls of elevator, elevator 56 passes through T type slider and T type spout cooperation and crane 2 looks slidable mounting, set up T type slider and make elevator 56 not only bear its gravity by lifter 54, its crane 2 also can share elevator 56's gravity through T type spout and T type slider cooperation, can carry on spacingly to elevator 56 simultaneously, the off normal shake phenomenon appears when avoiding elevator 56 to carry and reciprocate.

In addition, the invention also provides a use method of the rubber and plastic heat-insulating sleeve fixed-length sleeving and mounting machine, which comprises the following steps:

s1, clamping and fixing the pipeline: sleeving a pipeline on a screw rod 66, fixing the bottom of the pipeline on the upper end face of a connecting column 65, starting a clamping motor 61, driving a clamping ring 64 to rotate, enabling an outer clamping block 67 to clamp the outer side wall of the pipeline, driving the connecting column 65 to rotate by the clamping ring 64, further driving the screw rod 66 to rotate, and enabling moving sliders 681 at two ends of a tension spring 684 to move towards a compression tension spring 684 so as to enable an inner clamping block 682 to clamp the inner side wall of the pipeline;

s2, sleeve locking and fixing: one end of the sleeve is fixed on the mounting and locking frame 75, and the sleeve is fixed on the outer wall of the mounting and locking frame 75 by the locking ring 71 through the matching of the locking bolt 72 and the locking nut 73;

s3, rotating and lifting the suit: the driving motor 51 is started, the rotating shaft 511 and the lifting rod 54 are driven to rotate in a bevel gear meshing mode, the rotating shaft 511 drives the clamping frame 63 to rotate, the clamping frame is further driven to rotate, the lifting rod 54 enables the lifting block 56 to move downwards, the lifting block 56 drives the sleeves to move downwards together through the locking mechanism 7, and therefore the sleeves are sleeved on the pipelines.
