Five, the specific embodiment
The present invention does not receive the restriction of following embodiment, can confirm concrete embodiment according to technical scheme of the present invention and actual conditions.
Below in conjunction with embodiment and accompanying drawing the present invention is further described:
Shown in accompanying drawing 1 to 5, this pre-compaction lifting type roller frame that is used for fixing weldment comprises base for supporting 1, installing rack 2, active roller 3, return idler 4, pipe fitting conveying, lifting device and pre-compressing device; Between two base for supporting 1, be installed with installing rack 2, at least two support roller 5 is installed in the bottom of each base for supporting 1, the active roller 3 and the return idler 4 that are separately installed with mutual correspondence and can rotate at the left part of installing rack 2 and right part; On the installing rack 2 at active roller 3 and return idler 4 the place aheads and rear, pipe fitting being installed carries and lifting device; The pre-compressing device that can compress pipe fitting between active roller 3 and the return idler 4 is being installed on the installing rack 2, on installing rack 2, is being installed with and drives the variable-frequency motor that active roller 3 rotates.
Can according to actual needs above-mentioned pre-compaction lifting type roller frame be done further to optimize or/and improve:
Like accompanying drawing 1,2,3, shown in 5, pipe fitting is carried, lifting device comprise before riser action wheel 6, back riser action wheel 7, initiatively riser tugboat 8, driven riser tugboat 9, preceding lifting hydraulic cylinder 10 and back lifting hydraulic cylinder 11; On active roller 3 and return idler 4 front sides and the pairing installing rack 2 of rear side, be fixed with a pair of front support stand 12 and a pair of rear support stand 13 respectively; Riser action wheel 6 before between a pair of front support stand 12, being hinged with is hinged with back riser action wheel 7 between a pair of rear support stand 13; The two ends of preceding riser action wheel 6 have a pair of before riser support reinforcement plate 14; The lower end that riser supports reinforcement plate 14 before a pair of is fixed together with the two ends of preceding riser action wheel 6 respectively; Before a pair of, through bearing the active riser tugboat 8 that can rotate is installed between the upper end of riser support reinforcement plate 14, on installing rack 2, is installed with and drives the initiatively phase asynchronous variable-frequency motor of riser tugboat 8 rotations; The two ends of riser action wheel 7 have a pair of back riser to support reinforcement plate 15 in the back; The lower end that a pair of back riser supports reinforcement plate 15 is fixed together with the two ends of back riser action wheel 7 respectively; Support at a pair of back riser between the upper end of reinforcement plate 15 through bearing be equipped with can rotate and with active riser tugboat 8 corresponding driven riser tugboats 9; Lifting hydraulic cylinder 10 and back lifting hydraulic cylinder 11 before the front side of installing rack 2 and rear side are installed with; Before outer end and the preceding riser action wheel 6 of piston rod of lifting hydraulic cylinder 10 be fixedly installed togather and can make before 6 rotations of riser action wheel; The outer end of the piston rod of back lifting hydraulic cylinder 11 is fixedly installed togather with back riser action wheel 7 and back riser action wheel 7 is rotated; Like this; At first pipe fitting is placed on initiatively on the riser tugboat 8 during work, start phase asynchronous variable-frequency motor riser tugboat 8 is rotated and make pipe fitting to driven riser tugboat 9 directions move and seat on active riser tugboat 8 and driven riser tugboat 9, before driving then lifting hydraulic cylinder 10 with back lifting hydraulic cylinder 11 and before making riser action wheel 6 rotate with back riser action wheel 7; Riser tugboat 8 moves downward with driven riser tugboat 9 thereby make initiatively, and last pipe fitting seat is between active roller 3, return idler 4.
Shown in accompanying drawing 1 to 5, pipe 16, outer tube 17, pinch roller cantilever 18, pinch roller gripper shoe 19, pinch roller 20 and pinch roller hydraulic cylinder 21 in pre-compressing device comprises; The lower end of interior pipe 16 is fixedly mounted on the installing rack 2, in interior pipe 16, leading screw 22 is arranged, and manages 16 top and is installed with rotary handle 23 in stretch out the upper end of leading screw 22; Nut 24 is installed on the screw thread of leading screw 22, the slotted hole 25 of mutual correspondence is arranged on inner tubal wall vertically, be set with outer tube 17 in the outside of interior pipe 16; Outer tube 17 is fixedly installed togather with nut 24 and can moves up and down along slotted hole 25, and the left part of pinch roller cantilever 18 has left opening 26, and the middle part of outer tube 17 is positioned at left opening 26 and hinged with pinch roller cantilever 18; Right part at pinch roller cantilever 18 has right opening 27; On right opening 27, be installed with connecting axle 28, be set with a pair of pinch roller gripper shoe 19 at the two ends of connecting axle 28, a pair of pinch roller 20 that can compress pipe fitting is installed between a pair of pinch roller gripper shoe 19; Left end at left opening 26 is installed with fixed axis 29; On installing rack 2, be installed with pinch roller hydraulic cylinder 21, the upper end of the piston head of pinch roller hydraulic cylinder 21 and fixed axis 29 are fixedly installed togather, like this; Pinch roller 20 drives leading screw 22 drive outer tubes 17 through rotation rotary handle 23 and moves up and down; Pinch roller 20 is transferred to the appropriate location in advance, treat that pipe fitting place to be accomplished or after the pipe fitting welding accomplishes, pinch roller cantilever 18 is rotated up and down just can make pinch roller 20 compress pipe fitting through pinch roller hydraulic cylinder 21 and perhaps unclamp pipe fitting.
Like accompanying drawing 1,3, shown in 5, initiatively riser tugboat 8 and driven riser tugboat 9 all are big dolioform in intermediate narrower two, so just can guarantee that in the riser process pipe fitting is positioned at the middle part of active riser tugboat 8 and driven riser tugboat 9 and can overturn to both sides.
Like accompanying drawing 1,2, shown in 5; There is open slot 30 at the middle part of installing rack 2; At least four pairs bearing block installing hole 31 is arranged on the installing rack 2 of open slot 30 both sides, and active roller 3 is corresponding with open slot 30 with return idler 4, and active roller 3 is installed in the bearing block 32 through bearing with return idler 4; And bearing block 32 is fixedly mounted on the installing rack 2 through bolt and bearing block installing hole 31; Like this, when the diameter of pipe fitting not simultaneously, can bearing block 32 be installed in the spacing of adjusting active roller 3 and return idler 4 in the bearing block installing hole 31 of diverse location.
According to actual needs, preferably there is the outer insulation fat of annotating in the outside of active roller 3, and like this, its wheel than outer notes rubber is more durable.
Above technical characterictic has constituted most preferred embodiment of the present invention, and it has stronger adaptability and best implementation result, can increase and decrease non-essential technical characterictic according to actual needs, satisfies the demand of different situations.
