Example

[0039] For traditional buffer roller frames, their structure is usually as follows: Figure 1 As shown, the idler assembly includes: a first inclined buffer roller 1, a horizontal buffer roller 2, and a second inclined buffer roller 3. The first inclined buffer roller 1, the horizontal buffer roller 2, and the second inclined buffer roller 3 are fixedly installed on a crossbeam 4, and threaded fixing plates 5 are fixed to both ends of the bottom of the crossbeam 4. Because the upper surface of the idler assembly is in close contact with the conveyor belt, under these conditions, replacing one or more idlers in the idler assembly requires the use of relatively large tools or equipment to pry up the conveyor belt to obtain the space needed for replacing the idlers; the aforementioned operation is not only highly dangerous but also difficult and inefficient.

[0040] This embodiment provides a lifting roller frame, such as Figure 2 As shown, the lifting roller frame includes a crossbeam 4, a first end frame 6 and a second end frame 7, as well as a pair of adjusting frames 8, a pair of first support frames 9, and a pair of second support frames 10.

[0045] In this embodiment, combined with Figure 2 and Figure 3 It should be noted that: the width of the first support frame 9 is equal to the width of the upright plate 12; the width of the second support frame 10 is less than the width of the upright plate 12; and the sum of the heights of the side plates 17 corresponding to the first support frame 9 and the second support frame 10 is equal to the height of the upright plate 12.

[0046] In this embodiment, combined with Figure 2 and Figure 3The top support plate 11 and the top plate 16 of the first support frame 9 are provided with matching first threaded hole groups; the bottom plate 18 of the first support frame 9 and the top plate 16 of the second support frame 10 are provided with matching second threaded hole groups; the side plate 17 of the second support frame 10 and the bottom of the upright plate 12 are provided with matching third threaded hole groups.

[0047] It should be noted that, in combination Figure 2 and Figure 3 The first threaded hole group includes: a plurality of first threaded holes 21 symmetrically opened at the middle position of the top support plate 11 and the first support frame 9; the top support plate 11 and the first support frame 9 can be structurally fixedly connected based on the first fixing screw-nut assembly 23;

[0050] In this embodiment, combined with Figure 2 and Figure 3 The top plate 16 of the second support frame 10 is symmetrically fixed with multiple fixing nuts 27; the top support plate 11 has a circular through hole adapted to the adjusting screw 28; one adjusting screw 28 is adapted to one fixing nut 27; each adjusting screw 28 is nested with an adjusting nut 29; it should be noted that the adjusting screw 28 has an external thread, the fixing nut 27 has an internal thread groove adapted to the external thread at the bottom end of the adjusting screw 28, and the adjusting nut 29 has an internal thread adapted to the external thread in the middle of the adjusting screw 28;

[0051] Based on the aforementioned structure, combined with Figure 2 and Figure 3 The first support frame 9 can provide support for the top support plate 11, and the adjusting nut 29 can provide auxiliary support for the top support plate 11;

[0052] Specifically, this manifests as: when the structure is as follows Figure 2As shown, the first support frame 9 and the adjusting nut 29 together support the top support plate 11. When all the third fixing nuts in the first fixing screw-nut assembly 23, the second fixing screw-nut assembly 24 and the third fixing screw-nut assembly 25 are manually removed, all the first support frames 9 are manually removed, and all the adjusting nuts 29 are manually rotated downwards along the adjusting screw 28 to the same height, the crossbeam 4, together with the adjusting frames 8 that fix its two ends, falls freely until the bottom surface of the top support plate 11 touches the top of the adjusting nut 29. At this time, only the adjusting nut 29 provides support for the top support plate 11. At this time, the first inclined buffer roller 1, the horizontal buffer roller 2 and the second inclined buffer roller 3 have all been removed from the conveyor belt, making it more convenient and faster to replace the idler rollers.

[0053] After the "replacement of the idler roller" is completed, manually raise the "adjusting frame 8 that fixes both ends of the crossbeam 4" to the original height, manually rotate all the adjusting nuts 29 upward along the adjusting screw 28 to the original height, and reset all the first support frame 9. Based on all the first fixing screw-nut assembly 23, the second fixing screw-nut assembly 24 and the third fixing screw-nut assembly 25, structurally fix the first support frame 9.
