Specific embodiment
The present invention will be further described below in conjunction with the accompanying drawings, and protection scope of the present invention is not limited to as described below：
As Figure 1-Figure 2, a kind of pipe racking device for continuous bimetallic tube roller, including：Stent 1 and 12, leading screw 11, feed rod
3rd, split cylinder（On to cylinder 4 and lower to cylinder 5）, variable-frequency motor 14, shaft coupling 13, limit spring 8, nut block 9, spherical axis 7, stroke
Switch 2, tentacle 10；Stent 1 and 12 is mounted on the support arm of roller, and the both ends of feed rod 3 and leading screw 11 are mounted on stent 1 and 12
On, wherein leading screw 11 is connect with stent 1 and 12 using bearing；Right support 12 and motor base 15 are using welding, and by variable-frequency electric
Machine 14 is fixed on motor base 15, and 14 output shaft of variable-frequency motor is connect by shaft coupling 13 with leading screw 11.
The split cylinder is included to cylinder 4 and lower to cylinder 5, on to cylinder 4 and it is lower cylinder 5 is bolted, cylinder is done
Into the form of split cylinder, continuous bimetallic tube is facilitated to be put into pipe racking device.
The spherical axis 7 is mounted on the top of nut block 9, and is connected to the lower lower part to cylinder 5, and spherical axis 7 connects
Under to cylinder 5 and nut block 9, be in order to prevent since the resistance suffered by split cylinder is transmitted to nut block 9 so that nut block 9 is in silk
It is blocked in thick stick 11.
There are one through-hole, there are one threaded hole, nut blocks 9 at middle part to be threaded into leading screw for 9 lower part of nut block
11, when 11 both ends of leading screw are fixed, nut block 9 can move；Feed rod 3 pierces into nut block 9 by through-hole, and feed rod 3 can limit spiral shell
The rotation of mother tuber 9.
The limit spring 8 each side there are two, upper end is fixed on lower to cylinder 5, and lower end is fixed on nut block 9,
Limit spring 8 is to limit split cylinder（On to cylinder 4 and lower to cylinder 5）It is toppled due to the resistance by continuous bimetallic tube
The phenomenon that.
The travel switch 2 is mounted on the inside of two stents 1 and 12 in left and right, close to the top of feed rod 3, travel switch
2 be for the ease of carrying out comb operation to continuous bimetallic tube, and travel switch operation is primary, thus it is possible to vary variable-frequency motor 14 turns
To so as to make 9 counter motion of nut block, and then changing comb direction.
The tentacle 10 is mounted at left and right sides of nut block, and contour with travel switch 2, when nut block 9 moves to
During Derivative limit on the left or on the right position, tentacle 10 touches travel switch 2, changes the rotation direction of variable-frequency motor 14, and then change comb direction.
The roller bearing 16 is embedded in the lower bottom to cylinder 5, and 16 axis of roller bearing is parallel to the lower radial direction to cylinder 5, roller bearing
16 roll around axis, and roller bearing 16 is in order to which continuous bimetallic tube and the lower sliding friction between cylinder 5 are changed into rolling friction, subtracted
Frictional force of the small rolling in closed tube operation.
In embodiment, variable-frequency motor 14 starts, and leading screw 11 is driven to rotate by shaft coupling 13, nut block 9 is in leading screw 11
Under the action of move, when nut block 9 moves to limit on the left position, the stroke that the tentacle 10 in the left side of nut block 9 touches left side is opened
2 are closed, variable-frequency motor 14 rotates backward, and the rotation of 11 direction of leading screw drives 9 drawback movement of nut block；When nut block 9 moves to right pole
During extreme position, the tentacle 10 on 9 right side of nut block touches the travel switch 2 on right side, and variable-frequency motor 14 changes direction of rotation again, band
The dynamic counter motion again of nut block 9；In 9 motion process of nut block, split cylinder（On to cylinder 4 and lower to cylinder 5）It can be by continuous
The cornering force of bimetallic tube, therefore using spherical axis 7 come attaching nut's block 9 and lower to cylinder 5, retaining nut block 9 and leading screw
11 is horizontal, makes 9 internal thread not run-off the straight of nut block, nut block 9 is avoided to be blocked with leading screw 11；Due to split cylinder（On to 4 He of cylinder
Under to cylinder 5）When having the tendency that overturning under the lateral force of continuous bimetallic tube, side limit spring 8 is pressurized at this time, another
8 tension of side limit spring, so that split cylinder（On to cylinder 4 and lower to cylinder 5）It sets back；Under to 5 bottom of cylinder be embedded with roller bearing
16 so that continuous bimetallic tube and the lower rubbing action between cylinder 5 become rolling friction from sliding friction, reduce frictional force,
Reduce the loss of continuous bimetallic tube, while roller closed tube operating efficiency is improved.
The above is only the preferred embodiment of the present invention, it should be understood that the present invention is not limited to described herein
Form is not to be taken as the exclusion to other embodiment, and available for other combinations, modifications, and environments, and can be at this
In the text contemplated scope, modifications can be made through the above teachings or related fields of technology or knowledge.And those skilled in the art institute into
Capable modifications and changes do not depart from the spirit and scope of the present invention, then all should be in the protection domain of appended claims of the present invention
It is interior.
