Description

Technical Field:

[0001] The utility model relates to the technical field of idler groups, in particular to an extendable and angle-adjustable idler group. Background Art:

[0002] The idler group is used to support the conveyor belt, and mostly consists of an idler frame, a middle idler, a left idler, and a right idler. Since the idlers in the idler group are in long-term contact and friction with the belt, over time, the idlers in the idler group will inevitably be worn, etc., so it is necessary to regularly replace the idlers in the idler group.

[0003] In the prior art, when replacing the idlers in the existing traditional idler group, it is necessary to first lift the belt by a crane, and then the operator enters the frame to replace each idler. Not only is the overall operation more troublesome and less efficient, but there are also certain safety hazards. Summary of the Utility Model:

[0004] The purpose of the utility model is to provide an extendable and angle-adjustable idler group for the deficiencies existing in the prior art, which can replace the idlers in the idler group without disassembling the belt and without lifting the belt by a crane. Not only is the overall operation more convenient and efficient, but the operator does not need to enter the frame, which can improve safety.

[0005] To achieve the above purpose, the technical scheme adopted by the utility model is: an extendable and angle-adjustable idler group, including an idler frame, a middle idler, a left idler, and a right idler. The idler frame includes a middle bracket for placing the middle idler, a left bracket for placing the left idler, and a right bracket for placing the right idler. The idler frame also includes a mounting base, a sliding seat slidably connected to the mounting base in the left-right direction, a locking component for locking the sliding seat to the mounting base, and a limiting frame provided on the right side of the mounting base. The left bracket and the middle bracket are respectively arranged on the sliding seat. One end of the right bracket is hinged to the sliding seat, and a guide roller is provided at the other end of the right bracket. An arc-shaped guiding portion with a gradually increasing height from left to right is formed on the left side of the limiting frame, and the guide roller rolls on the arc-shaped guiding portion.

[0006] The further improvement of the above scheme is that the locking component includes an adjusting threaded rod sequentially passing through the sliding seat and the mounting base in the left-right direction, and a threaded rod nut for cooperating with the threaded rod.

[0007] The further improvement of the above scheme is that the locking component further includes a locking bolt sequentially passing through the sliding seat and the mounting base in the up-down direction, and a bolt nut for cooperating with the locking bolt.

[0008] A further improvement to the above solution is that the mounting base includes a sliding part in an inverted V-shaped structure, the sliding seat is in an inverted V-shaped structure, and the sliding seat is slidably connected to the sliding part of the mounting base.

[0009] A further improvement to the above solution is that hook parts are respectively formed at the front and rear ends of the sliding part, and each hook part respectively presses against the sliding seat downward.

[0010] A further improvement to the above solution is that a push-pull handle is provided on the sliding seat.

[0011] The beneficial effects of the present utility model are as follows: A retractable and angle-adjustable idler set provided by the present utility model includes an idler frame, an intermediate idler, a left idler, and a right idler. The idler frame includes an intermediate bracket for mounting the intermediate idler, a left bracket for mounting the left idler, and a right bracket for mounting the right idler. The idler frame further includes a mounting base, a sliding seat slidably connected to the mounting base in the left-right direction, a locking assembly for locking the sliding seat to the mounting base, and a limiting frame provided on the right side of the mounting base. The left bracket and the intermediate bracket are respectively arranged on the sliding seat. One end of the right bracket is hinged to the sliding seat, and the other end of the right bracket is provided with a guide roller. An arc-shaped guiding part with a gradually increasing height from left to right is formed on the left side of the limiting frame, and the guide roller rolls on the arc-shaped guiding part.

[0012] When the idler needs to be replaced in the present utility model, first loosen the locking assembly, and then pull out the sliding seat from the mounting base. As the sliding seat is pulled out from below the belt, the intermediate idler, the left idler, and the right idler are also correspondingly pulled out from below the belt. Thus, the idlers in the idler set can be replaced without disassembling the belt and without lifting the belt by a crane. Not only is the overall operation relatively convenient and efficient, but also the operator does not need to enter the rack, which can improve safety. In addition, since the inclination angle of the right idler will change correspondingly when the sliding seat of the present utility model is pushed or pulled, the inclination angle of the right idler can also be adjusted by adjusting the position of the sliding seat, which has stronger practicability.

[0015] Description of reference numerals: idler support 1, intermediate support 11, left support 12, right support 13, mounting base 14, sliding part 141, hook part 142, sliding seat 15, locking assembly 16, adjusting threaded rod 161, threaded rod nut 162, locking bolt 163, bolt nut 164, limit frame 17, arc-shaped guiding part 171, guiding roller 18, push-pull handle 19, intermediate idler 2, left idler 3, right idler 4. Detailed implementation manner:

[0016] The following further describes the present utility model in conjunction with the attached drawings. As Figure 1-2 shown, the present utility model includes an idler support 1, an intermediate idler 2, a left idler 3, and a right idler 4. The idler support 1 includes an intermediate support 11 for mounting the intermediate idler 2, a left support 12 for mounting the left idler 3, and a right support 13 for mounting the right idler 4. The idler support 1 further includes a mounting base 14, a sliding seat 15 slidably connected to the mounting base 14 in the left-right direction, a locking assembly 16 for locking the sliding seat 15 to the mounting base 14, and a limit frame 17 provided on the right side of the mounting base 14. The left support 12 and the intermediate support 11 are respectively arranged on the sliding seat 15. One end of the right support 13 is hinged to the sliding seat 15, and a guiding roller 18 is provided at the other end of the right support 13. The left side of the limit frame 17 is formed with an arc-shaped guiding part 171 that gradually increases in height from left to right, and the guiding roller 18 rolls on the arc-shaped guiding part 171. When the present utility model needs to replace the idler, first loosen the locking assembly 16, and then pull out the sliding seat 15 from the mounting base 14. As the sliding seat 15 is pulled out from below the belt, the intermediate idler 2, the left idler 3, and the right idler 4 are also pulled out from below the belt accordingly. Thus, the idlers in the idler group can be replaced without disassembling the belt and without lifting the belt by a crane. Not only is the overall operation relatively convenient and efficient, but also the operator does not need to enter the frame, which can improve safety. In addition, since the inclination angle of the right idler 4 will change accordingly when the sliding seat 15 of the present utility model is pushed or pulled, the inclination angle of the right idler 4 can also be adjusted by adjusting the position of the sliding seat 15, making it more practical.

[0017] The locking assembly 16 includes an adjusting threaded rod 161 sequentially passing through the sliding seat 15 and the mounting base 14 in the left-right direction, and a threaded rod nut 162 for cooperating with the threaded rod. By rotating the adjusting threaded rod 161 clockwise or counterclockwise, the position of the sliding seat 15 relative to the mounting base 14 can be adjusted.

[0018] The locking assembly 16 further includes a locking bolt 163 that is sequentially inserted through the sliding seat 15 and the mounting base 14 in the up and down direction, and a bolt nut 164 that cooperates with the locking bolt 163; through the cooperation of the locking bolt 163 and the bolt nut 164, the force of locking the sliding seat 15 on the mounting base 14 can be increased, and it can more stably ensure that the sliding seat 15 will not shift relative to the mounting base 14, so that it can better ensure that the idler set can firmly and stably support and transmit the belt.

[0019] The mounting base 14 includes a sliding portion 141 having an inverted V-shaped structure. The sliding seat 15 has an inverted V-shaped structure, and the sliding seat 15 is slidably connected to the sliding portion 141 of the mounting base 14. Through the sliding portion 141 and the sliding seat 15 designed with an inverted V-shaped structure, it can better ensure that the sliding seat 15 only slides in the left and right directions, and it can better ensure that the idler set can firmly and stably support and transmit the belt.

[0020] Hook portions 142 are respectively formed at the front and rear ends of the sliding portion 141, and each hook portion 142 respectively abuts against the sliding seat 15 downward. Through the hook portions 142, it can further ensure that the sliding seat 15 will not shift in other directions relative to the mounting base 14, so that while meeting the requirements of a telescopic and retractable idler set, it can ensure that the idler set can firmly and stably support and transmit the belt.

[0021] A push-pull handle 19 is provided on the sliding seat 15, which makes it more convenient to push and pull the sliding seat 15 through the push-pull handle 19, and the practicability is stronger.

[0022] Working principle:

[0023] When it is necessary to replace the idlers, first loosen the locking assembly 16, and then pull out the sliding seat 15 from the mounting base 14. As the sliding seat 15 is pulled out from below the belt, the middle idler 2, the left idler 3, and the right idler 4 are also correspondingly pulled out from below the belt. After replacing each idler, push the sliding seat 15 back to the original position of the mounting base 14, and lock the sliding seat 15 on the mounting base 14 through the locking assembly 16 to complete the replacement of each idler in the idler set; the utility model can replace the idlers in the idler set without disassembling the belt and without lifting the belt by a crane. It is not only relatively convenient and efficient in overall operation, but also the operator does not need to enter the rack, which can improve safety.
