DETAILED DESCRIPTION
[0024] like Figure 1-3 As shown, a hopper elevator tensioning device; the device mainly relies on the movement of the outer adjustment plate 3 to complete the adjustment task. The tensioning shaft 2 is movably arranged on the inner side of the outer adjustment plate 3; the outer adjustment plate 3 is movably plugged into the side wall of the elevator base 1, and a guide column 5 is arranged on the side wall cross section corresponding to the plate surface of the outer adjustment plate 3; a through hole is arranged on the outer adjustment plate 3 at the position corresponding to the guide column 5, and the guide column 5 moves along the through hole; a spring 11 is sleeved on the guide column 5, and the spring 11 prevents the outer adjustment plate 3 from impacting the side wall of the elevator base 1 when the adjusting screw 6 is broken and cannot be tensioned by means of deformation and extrusion, thereby playing a buffering role and avoiding a secondary impact of the outer adjustment plate 3.
[0025] like Figure 3-6 As shown, the inner wall of the elevator base 1 is provided with guide strips 4 on both sides of the outer adjustment plate 3; the outer wall of the elevator base 1 is provided with a fixed seat 8; the fixed seat 8 is movably provided with an adjusting screw 6; the outer adjustment plate 3 is located at one end of the outer wall of the elevator base 1 and is inserted above the adjusting screw 6; one end of the adjusting screw 6 is connected to the driving end of the adjusting motor 7, and the motor should be a low-speed motor. The outer adjustment plate 3 is movably provided with a first guide wheel 9 corresponding to the inner wall position of the elevator base 1. The outer adjustment plate 3 is a U-shaped structure, one end of which is on the inner side of the elevator base 1 and the other end is on the outer side of the elevator, extending the movable part of the tensioning device to the outer side of the adjusting base. The outer adjustment plate 3 is movably provided with a second guide wheel 10 corresponding to the outer wall position of the elevator base 1. The guide wheel helps to reduce friction.
[0026] like Figure 2-6As shown, the fixed seat 8 includes a bottom plate 8.1 and a side plate 8.2; the adjustment motor 7 and the side plate 8.2 are fixed on the surface of the bottom plate 8.1; an adjustment screw 6 is rotatably arranged between the side plates 8.2; a bent protrusion 3.1 is arranged at the position where the adjustment screw 6 is passed through the outer adjustment plate 3, and the protrusion 3.1 moves between the side plates 8.2; and the second guide wheel 10 moves between the side plates 8.2. A mounting plate 12 is fixed at the side wall section of the elevator base 1, and a movable groove 12.1 is opened on the mounting plate 12 corresponding to the movable position of the outer adjustment plate 3. More than one set of sprockets 14 are arranged inside the elevator base 1; the sprockets 14 in the elevator base 1 and the sprockets 14 of the elevator are driven by chains 15, and a lifting bucket 13 is movably connected to the shaft between the chains 15. The lifting bucket 13 is responsible for conveying materials. If the fixing method is not separately introduced in the description, it is welded or screwed by common technical means of technical personnel in the industry.
[0027] Here’s how it works:
[0028] The motor drives the adjusting screw 6 to rotate by forward and reverse rotation, so that the outer adjusting plate 3 moves; the outer adjusting plate 3 is then tightened or loosened. The adjusting screw 6 needs to be oiled and maintained regularly. The tensioning device located outside the hoist base 1 can be provided with a protective cover.
