Abstract
The utility model relates to a tile type supporting mechanism for a pipeline cleaning robot, relating to the technical field of pipeline cleaning robots. One end of a motor is connected with a gearbox; a support frame is fixedly connected to the other end of the gearbox; an end cover is fixed at the other end of the support frame; a double-threaded screw is connected to the output end of the gearbox; a left-handed nut and a right-handed nut are respectively in threaded connection with the double-threaded screw between the support frame and the end cover; at least three support rods are uniformly distributed in the radial direction on the outer circumference of the support frame; a support tile is fixedly connected outside each support block; two stay bars are respectively connected with the inner end of each support block through pin rolls; the other end of each stay bar is respectively hinged with the left-handed nut and the right-handed nut through pin rolls; a torsion spring is sleeved on the double-threaded screw on the outer side of the end cover; and two ends of the torsion spring are respectively and fixedly connected with the double-threaded screw and the end cover. The tile type supporting mechanism disclosed by the utility model can provide a greater support force, and thus an axial thrust of the robot is increased and the tile type supporting mechanism contributes to being applied to conditions that the inner wall is smooth and lubricating oil exists.
Description
Technical field
The utility model relates to the pipeline cleaning robot technical field.
Background technology
Domestic existing pipeline cleaning robot; No matter be wheel protrusive or worm creeping-type; Their method for supporting all is to adopt roller to support, and this supporting way because coefficient of friction is bigger, can also provide certain thrust under the rough situation of inner-walls of duct; But lubricated oil condition is next can't creep fully at inner wall smooth and band, thereby causes the robot afunction; And, bring great difficulty for the sealing of robot and the cleaning after the use because the various parts of roller support appearance are more.
Summary of the invention
The utility model purpose provides a kind ofly can use the tile type supporting mechanism at the pipeline cleaning robot that smooth inwall is creeped.
The utility model comprises motor; End connection gear case at motor; It is characterized in that: the other end at gear-box is fixedly connected bracing frame, at the other end fixed connection end cap of bracing frame, at double threaded screw of output connection of gear-box; The free end of said double threaded screw is arranged in the axially extending bore of end cap, and a left-handed nut and a right-handed nut are threaded respectively on the double threaded screw between bracing frame and the end cap; Outer periphery at support frame as described above is uniformly distributed with at least three back-up blocks, outside each back-up block, is fixedly connected one respectively and supports tile; Connect two struts through pivot pin respectively in the inner of each back-up block, the other end of each strut is hinged through pivot pin and left-handed nut and right-handed nut respectively; On the double threaded screw in the said end cap outside, be nested with torsion spring, the two ends of said torsion spring are fixedly connected with end cap with double threaded screw respectively.
The utility model at first adopts gear-box that the little moment of torsion of motor output is amplified in the transmission of power; Utilize then positive and reverse return to double threaded screw will rotatablely move and change the axial linear movement of left and right spin nut into; Through strut power is synthesized, amplified and acts on the back-up block again, make each back-up block drive respectively support tile and do radial motion.Establish the torsion spring that is added with at double threaded screw one end, the purpose of automatic drawing back in the time of can playing the tile outage.
Can adjust tile support force size through regulating the motor output torque; The utility model adopts the tile of face contact type to support; Very big support force can be provided, thereby improve the axial thrust of robot, can be applied under the lubricated oil condition of inner wall smooth and band.The utility model Installation and Debugging are very convenient, and sealing simultaneously also is very easy to, the cleaning after easy to use.
The utility model is rubber ring of overall budget outside each said support tile also, can further increase coefficient of friction, also can play certain sealing function.
In order to prevent that torsion spring from coming off, the utility model is also arranged pressing plate outside said torsion spring, and said pressing plate is fixed on the end cap.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Fig. 2 is the right side view of Fig. 1.
The specific embodiment
Like Fig. 1, shown in 2, the utility model is at an end connection gear case 2 of motor 1, at the other end fixed connection bracing frame 3 of gear-box 2, at the other end fixed connection end cap 4 of bracing frame 3.
Output at gear-box 2 connects a double threaded screw 5, and the free end of double threaded screw 5 is arranged in the axially extending bore of end cap 4.A left-handed nut 6 and a right-handed nut 7 along its length are threaded respectively on the double threaded screw 5 between bracing frame 3 and the end cap 4.Evenly be fixedly connected four Connection Blocks 8 at left-handed nut 6 radial outsides, evenly be fixedly connected four Connection Blocks 9 at right-handed nut's 6 radial outsides, each Connection Block 8 is arranged in same footpath respectively upwards correspondingly with each Connection Block 9.
Outer periphery at bracing frame 3 is uniformly distributed with four back-up blocks 10, outside each back-up block 10, is fixedly connected one through pin 11 respectively and supports tile 12.
The inner at each back-up block 10 connects two struts 14 and 15 through pivot pin 13 respectively, and the other end of strut 14 is hinged through pivot pin 16 and Connection Block 8, and the other end of strut 15 is hinged through pivot pin 117 and Connection Block 9.
On the double threaded screw 5 in end cap 4 outsides, be nested with torsion spring 18, the two ends of torsion spring 18 are fixedly connected with end cap 4 with double threaded screw 5 respectively.Outside torsion spring 18, arrange pressing plate 19, pressing plate 19 is fixedly connected on the end cap 4 through bolt 20.
Support rubber ring 21 of overall budget outside the tile 12 at four.
