The described circular hinge of living is equipped with three supports, and it becomes hexagonal angle in twos, and support is formed by four rod hinge connections, forms parallelogram sturcutre.
Described Y type support is made of three bridges that become hexagonal angles and its end is provided with brake pad.
Described air bag is toroidal, and it realizes inflation/deflation by the aerating and exhaust device that is arranged on upper spacer.
The invention has the beneficial effects as follows:
Adopt the dredging of drive motors and frame for movement, simple in structure, simplified control circuit, can realize the moving up and down of any angle of inclination pipe, dredging and cleanser conduit etc. by air bag and support motion.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further described:
As shown in Figure 1, the present invention includes support 2, the circular hinge 4 of living, shield 7, pointed cone 8, Y type support 9, telescoping mechanism 10, control circuit 11, air bag 13, cleaning disk 15 etc.Telescoping mechanism 10 1 ends connect threaded axis 3, and the other end connects upper spacer 12.being connected bolster 6 between upper spacer 12 and lower clapboard 14 connects, the air bag 13 that is between upper spacer 12 and lower clapboard 14 is installed on described bolster 6, air bag 13 is toroidal, it realizes inflation/deflation by the aerating and exhaust device 5 that is arranged on upper spacer 12, air bag 13 is regulated the volume of air bag by the tolerance of aerating and exhaust device 5, when air bag becomes large, air bag 13 is affixed with tube wall 1, powerful pressure strengthens the frictional force of 1 of air bag 13 and tube wall, for pointed cone 8 dredging pipelines provide larger axial force lower clapboard 14 opposite side relative with air bag 13, cleaning disk 15 is installed, the axle head that bolster 6 passes cleaning disk 15 is equipped with shield 7, the outside of shield 7 is equipped with some tip of a root cones 8.The circular hinge 10 of living movable up and down is installed on described described axis 3, on the circular hinge 10 of living, extensible support 2 is installed, the circular hinge 4 of living is equipped with three supports 2, and it becomes hexagonal angle in twos, support 2 is formed by four rod hinge connections, forms parallelogram sturcutre.Support 2 is connected with telescoping mechanism 10 by threaded axis 3, and telescoping mechanism 10 can be completed elongation and contraction process by drive motors.
The Y type support 9 that leans at pipeline 1 inwall is installed on support 2.Described Y type support 9 is made of three bridges that become hexagonal angles and its end is provided with brake pad 16, in the device motion process wherein two bars contact with tube wall.Y type support 9 and support 2 joints employing springs 17 can produce certain radially breathing amount and make support 9 be close to all the time pipeline 1 inwall.
The control circuit 11 that the present invention controls each parts is arranged on upper spacer 12, controls the actions such as the moving up and down of single unit system, dredging and cleanser conduit by this device.
The course of work of the present invention is as follows:
(1) vertical motion
When this device in the pipeline course of work, air bag 13 begins inflation, along with being on the increase of gas, air bag 13 is subject to the effect of upper spacer 12 and lower clapboard 14, lateral magnification when a certain amount of, has larger pressure when gas between air bag 13 and tube wall, axial friction is strengthened to can bearing load, stops inflation this moment; After device was stable, control circuit 11 sent signal and makes telescoping mechanism 10 elongations, and upper mechanism all rises, and support 2 launches, circular hinge 4 setting in motions of living, and chucking support 2 is completed uphill process.When needs rose continuously, next step was exitted air bag 13, then telescoping mechanism 10 is shortened, make the parts of downside increase, then to air bag 13 inflations, make air bag 13 and tube wall close contact, continue to make telescoping mechanism 10 elongations, repeat said process and can make device in the interior continuous rising of pipeline 1.
(2) down maneuver
In the pipeline course of work, three Y type supports 9 are 120 ° in twos when this device, and Y type support 9 wherein two bars is close to round tube inner wall, and drive motors 20 driven wheels make screw 18 rotations, make the circular hinge 4 of living increase, chucking support 2; After support 2 chuckings, control circuit 11 sends signal and makes telescoping mechanism 10 elongations, and lower mechanisms all descends, and air bag 13 begins inflation and directly is full of, and completes the decline process.As think continuous decline, repeat the decline process and get final product.
(3) dredging and cleaning action
In the pipeline course of work, air bag 13 is clamped in pipe when this device, and control circuit 11 sends signal moves downward pointed cone 8, dredging pipeline.Simultaneously, cleaning disk 15 begins rotation, removes the tube wall residue.
The undeclared part that relates in the present invention is same as the prior art.
