Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveying equipment technology, and in particular to an inclined roller support. Background Technology
[0002] Currently, roller conveyor lines are often used in logistics transfer, production line connection and warehousing systems to transport goods; roller conveyor lines are composed of core components such as idlers, idler frames and conveyor belts;
[0003] Traditional standard load-bearing idler frames are integral fixed frame structures equipped with load-bearing idlers, serving only the single function of supporting the conveyor belt and materials. However, since idlers are consumable parts, they usually need to be replaced after a period of use. But the traditional load-bearing idler frame is a fixed bracket structure, which causes the upper surface of the load-bearing idler to be in close contact with the conveyor belt, and the idler is crushed by the conveyor belt from below. In this case, replacing the load-bearing idler requires the use of large tools or equipment to pry up the conveyor belt to create the space needed to replace the idler. The aforementioned operation is not only dangerous, but also difficult and inefficient.
[0004] To solve the aforementioned technical problems, it is urgent to propose an inclined roller support. Summary of the Invention
[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides an inclined idler bracket, which solves the technical problem of "how to efficiently replace the load-bearing idler while reducing the operational risk factor" in the existing load-bearing idler brackets of roller conveyor lines.

[0017] Optionally, when the connecting plate is attached to the upper surface of the crossbeam, the edge of the connecting plate is aligned with the edge of the crossbeam, and the second threaded fixing hole is aligned with the first threaded fixing hole.
[0018] Optionally, the 45-degree deflection limiting piece is a right-angled trapezoidal metal plate; the inclination angle of the hypotenuse of the right-angled trapezoidal metal plate is 45 degrees;

[0030] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art. Example
[0031] For traditional load-bearing idler frames, their structure is typically as follows: Figure 1 As shown, the first inclined support roller 1, the second inclined support roller 2, and the flat support roller 3 are assembled on the fixing rod 4, which is fixedly installed on the conveyor frame based on two crossbeams 5. Because the upper surfaces of the first inclined support roller 1, the second inclined support roller 2, and the flat support roller 3 are in close contact with the conveyor belt, replacing one or more of these rollers requires using large tools or equipment to lift the conveyor belt to create the space needed for replacement. This operation is not only highly dangerous but also difficult and inefficient.
[0032] This embodiment provides an inclined roller support, such as Figure 2 As shown, it includes one fixed base 6 and two crossbeams 5; combined with Figure 2 and Figure 3 The fixed base 6 is a structure in which the upper edge of the upwardly inclined metal plate 7 is welded and fixed to the upper edge of the downwardly inclined metal plate 8; the welding and fixing angle is 90 degrees.
[0033] In this embodiment, as Figure 2 As shown, the top two ends of the fixed base 6 are fixed with a first end fixing frame 9 and a second end fixing frame 10; the top of the fixed base 6 is fixed with a first middle fixing frame 11 and a second middle fixing frame 12 at three equal positions; the first middle fixing frame 11 is close to the first end fixing frame 9 relative to the second middle fixing frame 12.
[0034] In this embodiment, as Figure 2 As shown, the first inclined bearing idler 1 is detachably connected at both ends to the first end fixing frame 9 and the first middle fixing frame 11; the second inclined bearing idler 2 is detachably connected at both ends to the second middle fixing frame 12 and the second end fixing frame 10; and the flat bearing idler 3 is detachably connected at both ends to the first middle fixing frame 11 and the second middle fixing frame 12.
[0035] In this embodiment, as Figure 3As shown, the crossbeam 5 is a rectangular metal plate with first threaded fixing holes 13 symmetrically provided at the front and rear ends of the plate surface; the two crossbeams 5 are parallelly fixedly assembled to the belt conveyor frame based on the corresponding first threaded fixing holes 13.
[0036] In this embodiment, as Figure 3 As shown, a bearing 14 is fixed at the vertical midpoint of the long side of the top surface of the crossbeam 5, and a rotating shaft 15 is fixedly nested inside the bearing 14; the axial length of the bearing 14 is equal to the length of the short side of the crossbeam 5, and less than the axial length of the rotating shaft 15.
[0037] In this embodiment, it should be noted that the exposed portion of the rotary shaft 15 relative to the bearing 14 includes: an outer exposed end and an inner exposed end;
[0038] The inner exposed ends of the two rotating shafts 15 are of the same length and face each other; the outer exposed ends of the two rotating shafts 15 are of the same length and face each other.
[0039] In this embodiment, combined with Figure 2 and Figure 3 The two ends of the upward-inclined metal plate 7 are symmetrically provided with: a rectangular notch 17 adapted to the width of the crossbeam 5, and a 45-degree deflection limiting piece 16.
[0040] Among them, combined Figure 2 and Figure 3 The aforementioned 45-degree deflection limiting plate is a right-angled trapezoidal metal plate; the inclination angle of the hypotenuse of the right-angled trapezoidal metal plate is 45 degrees; the lower base of the right-angled trapezoidal metal plate is vertically fixed to both ends of the upward-inclined metal plate 7, and satisfies the following conditions: the hypotenuse of the right-angled trapezoidal metal plate faces upward, and the right-angled side of the right-angled trapezoidal metal plate faces downward.
[0041] In this embodiment, combined with Figure 2 and Figure 3 The lower edges of both ends of the downward inclined metal plate 8 are symmetrically welded with connecting plates 18 adapted to the crossbeam 5; the welding angle between the connecting plate 18 and the corresponding downward inclined metal plate 8 is 135 degrees; the connecting plate 18 is provided with a second threaded fixing hole 19 adapted to the first threaded fixing hole 13.
[0042] In this embodiment, combined with Figure 2 and Figure 3 When the connecting plate 18 is attached to the upper surface of the crossbeam 5, the edge of the connecting plate 18 is aligned with the edge of the crossbeam 5, and the second threaded fixing hole 19 is aligned with the first threaded fixing hole 13.
[0043] In this embodiment, combined with Figure 2 and Figure 3The fixed base 6 is symmetrically fixed on the inner side below both ends with: a bushing 20 that is nested and adapted to the inner exposed end of the rotating shaft 15; the axial length of the inner exposed end is not less than the axial length of the bushing 20.
[0044] One method for replacing idlers based on the aforementioned inclined idler bracket is as follows:
[0045] When any one or more of the first inclined load-bearing idler 1, the second inclined load-bearing idler 2, and the flat load-bearing idler 3 need to be replaced, first, power off the equipment and stop operation to ensure safety. Then, manually unscrew the fixing screws that are simultaneously fixed to the first threaded fixing hole 13 and the second threaded fixing hole 19. Then, manually push the inclined idler bracket to one side by 45 degrees. Specifically, while the bushing 20 rotates 45 degrees around the rotating shaft 15, the first inclined load-bearing idler 1, the second inclined load-bearing idler 2, and the flat load-bearing idler 3 deflect 45 degrees with the fixed base 6, thereby driving the first inclined load-bearing idler 1, the second inclined load-bearing idler 2, and the flat load-bearing idler 3 to detach from the upper belt surface. In this state, any one or more of the first inclined load-bearing idler 1, the second inclined load-bearing idler 2, and the flat load-bearing idler 3 can be replaced.
[0046] After replacing the idler rollers, manually push them in the reverse direction to restore the inclined idler roller bracket, which is tilted at 45 degrees, to a vertical position, so that the first inclined load-bearing idler roller 1, the second inclined load-bearing idler roller 2, and the flat load-bearing idler roller 3 can contact the upper belt surface. Then, manually tighten the fixing screws that are simultaneously fixed to the first threaded fixing hole 13 and the second threaded fixing hole 19. Finally, restore the power to the equipment and start the conveying operation.
[0047] For the inclined idler bracket described in the aforementioned embodiment 1, a bearing 14 is fixed at the vertical midpoint of the long side of the top surface of the crossbeam 5, and a rotating shaft 15 is fixedly nested inside the bearing 14; the lower inner sides of both ends of the fixed base 6 are symmetrically provided with bushings 20 that are nested and adapted to the inner exposed end of the rotating shaft 15; and both ends of the upward inclined metal plate 7 are symmetrically provided with rectangular notches 17 adapted to the width of the crossbeam 5; thereby ensuring that the fixed base 6, which is fixed at the top of the first inclined bearing idler 1, the second inclined bearing idler 2, and the flat bearing idler 3, can deflect around the rotating shaft 15 as the central axis to drive the corresponding bearing idler to detach from the upper belt surface; thus avoiding "unnecessary damage to the conveyor belt during the replacement of bearing idlers", and reducing "the difficulty of operation for the replacement operator and improving the efficiency of idler replacement".
[0048] For the inclined roller bracket described in the first embodiment, 45-degree deflection limiting plates 16 are symmetrically provided at both ends of the inclined metal plate 7; the 45-degree deflection limiting plates 16 ensure that the fixed base 6 can be quickly and accurately rotated 45 degrees, thereby improving operating efficiency.
[0049] For the inclined roller bracket described in the aforementioned embodiment 1, the edge of the connecting plate 18 is aligned with the edge of the crossbeam 5, and the second threaded fixing hole 19 is aligned with the first threaded fixing hole 13; by fixing the screw, the connection between the fixed base 6 and the crossbeam 5 can be ensured based on the second threaded fixing hole 19 and the first threaded fixing hole 13.
