Description

[0026] The winding mechanism 18 comprises a mounting box 19, a wire inlet 20 arranged on one side of the mounting box 19, a winding roller 27 located in the interior of the mounting box 19, limiting flapper plates 25 respectively fixedly connected with two ends of the winding roller 27, a first rotating shaft 24 connected with one end of one limiting flapper plate 25 and rotatably connected with one side of the interior of the mounting box 19, a second rotating shaft 28 connected with one end of the other limiting flapper plate 25 and rotatably connected with the mounting box 19, a hand wheel 29 connected with one end of the second rotating shaft 28 and located on the outside of the mounting box 19, a locking device arranged on the mounting box 19 and insertedly matched with one limiting flapper plate 25, ear plates 22 welded on one side of the mounting box 19 and respectively corresponding to both sides of the wire inlet 20, a guide roller 23 rotatably connected between the two ear plates 22 and forming a 120°-angle contact with the pull rope 17, the other end of the pull rope 17 passing through the wire inlet 20 and spirally winding on the outer wall of the winding roller 27, and the upper side of the mounting box 19 being connected with the lower end of the sliding column 12. The end of the pull rope 17 is fixed by a pressing plate bolt. The setting of the guide roller 23 is used to reduce the friction resistance of the movement of the pull rope 17. A plurality of limiting holes 26 in the shape of annular intervals are arranged on one limiting flapper plate 25, and the first rotating shaft 24 is located between the plurality of limiting holes 26; a threaded hole 21 is arranged on one side of the mounting box 19; the locking device comprises a handle 30 located on one side of the mounting box 19, a moving column 31 connected with one end of the handle 30, a semispherical plug 32 connected with one end of the moving column 31 and insertedly matched with the plurality of limiting holes 26, external threads 33 arranged on the outer wall of the moving column 31, a stretching spring 34 sleeved on the moving column 31, both ends of the stretching spring 34 being tightly pressed against the outer wall of the mounting box 19 and the inner side of the handle 30 respectively, one end of the moving column 31 passing through the threaded hole 21 and extending to the interior of the mounting box 19, and the external threads 33 being threadedly matched with the threaded hole 21. The diameter of the semispherical plug 32 is greater than the diameter of the moving column 31, so that after the moving column 31 drives the semispherical plug 32 to move out of the limiting hole 26, the moving column 31 cannot move to the outside of the mounting box 19 through the threaded hole 21.

[0027] The supporting mechanism 2 comprises a bottom plate 3, four self-locking universal casters 4 (equipped with a foot pedal type wheel brake mechanism) arranged in a rectangular shape on the four corners of the lower side of the bottom plate 3, a first supporting column 5 and a second supporting column 6 arranged in intervals on the upper side of the bottom plate 3, and two reinforcing cross bars 7 respectively welded on both sides of the second supporting column 6, one end of one reinforcing cross bar 7 being welded with one side of the first supporting column 5, and one end of the other reinforcing cross bar 7 being welded with the outside of the mounting box 19, and one end of each of the first supporting column 5 and the second supporting column 6 being fixed with the outer wall of the screw conveyor body 1 by bolts; the common action of the first supporting column 5, the second supporting column 6, the two reinforcing cross bars 7, the mounting box 19, the sliding column 12 and the connecting column 13 improves the supporting stability of the screw conveyor body 1.

[0028] Working process and principle: during the operation of the device, when the distance between the discharge pipe 9 and the target device needs to be adjusted, the operator first holds and rotates the handle 30. The rotation of the handle 30 drives the moving column 31 to rotate synchronously, so that the external threads 33 on the moving column 31 are gradually unscrewed from the threaded holes 21 of the mounting box 19. After unscrewing, under the elastic pulling force of the tension spring 34, the handle 30 moves away from the mounting box 19, thereby driving the moving column 31 connected with the handle 30 to move. The movement of the moving column 31 causes the hemispherical plug 32 inserted into the limiting hole 26 to be pulled out, thereby releasing the locking restriction on the limiting disc 25. Then, the operator rotates the hand wheel 29 clockwise. The rotation of the hand wheel 29 drives the second rotating shaft 28 to rotate synchronously, and under the linkage of the first rotating shaft 24 and the second rotating shaft 28, the winding roller 27 starts to rotate, and the pull rope 17 is gradually wound on the winding roller 27. As the pull rope 17 is wound, it generates a downward pulling force on the connecting rod 15, causing the connecting rod 15 to move downward. The sleeve ring 16 connected with one end of the connecting rod 15 slides downward along the sliding column 12, and the other end of the connecting rod 15 drives the connecting ring 11 to move downward synchronously. In this process, the telescopic pipe 10 is stretched, the sleeve ring 16 synchronously stretches the compression spring 14, the connecting ring 11 gradually approaches the target device, and the distance between the discharge pipe 9 and the device is shortened. Conversely, when the operator rotates the hand wheel 29 counterclockwise, the winding roller 27 rotates in the opposite direction, and the pull rope 17 is gradually loosened. At this time, under the elastic restoring force of the compression spring 14, the sleeve ring 16 moves upward along the sliding column 12, the telescopic pipe 10 is retracted, the connecting ring 11 is lifted, and the distance between the discharge pipe 9 and the device is increased.

[0029] After the adjustment is completed, the operator pushes the handle 30 towards the mounting box 19, and then reversely rotates the handle 30. The external threads 33 on the moving column 31 are screwed into the threaded holes 21 again and tightly fit, and the hemispherical plug 32 is gradually inserted into the corresponding limiting hole 26, thereby locking the winding roller 27 to prevent the discharge pipe 9 from moving due to accidental rotation.

[0030] The device provides convenience for adjusting the distance between the discharge pipe 9 and the device for the spiral conveyor body 1 installed at a high position, solves the problem that workers need to use ladders or other climbing tools for operation due to the high installation position of the spiral conveyor body 1, not only reduces the complexity of operation and improves work efficiency, but also avoids the risk of falling from a high place that workers may face during climbing operation, and improves the safety and convenience of operation.

[0031] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principles of the present application shall be included in the protection scope of the present application.
