Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to a novel hydraulic automatic adjustment small radius continuous turning device. Background Technology

[0002] In belt conveyor projects across various industries, belt conveyors demonstrate extremely wide flexibility in their layout. When belt conveyors are arranged with a large turning radius, continuous turning devices can be installed to allow workers to freely and rationally plan the direction of the belt conveyor.

[0003] In coal mines, the frequent use of mining TBMs in recent years has created small-radius continuous turning roadways that are unsuitable for belt conveyors, leading to difficulties in slag removal. Although small-radius continuous turning conveyors have been adopted, their structures are mostly fixed or allow for minor manual adjustments. Their preset turning paths are ideal, but in actual use, with constant changes in belt tension, the belt swings back and forth at the turns (deviation), causing adjustment difficulties and unstable transport. Therefore, to address these problems, a novel hydraulic automatic adjustment device for small-radius continuous turning is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that cannot automatically adjust, and to propose a novel hydraulic automatic adjustment small-radius continuous turning device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel hydraulic automatic adjustment small-radius continuous turning device includes a fixed support and a movable support. The fixed support is equipped with an adjustment component, which includes a hydraulic pipe rotatably mounted on the fixed support. The movable support and the fixed support are symmetrically equipped with lifting and lowering hydraulic rods. The lifting and lowering hydraulic rods are used to adjust the tilt angle of the movable support. The rotation of the hydraulic pipe is used to adjust the rotation angle of the movable support. The changes in the tilt angle and rotation angle of the movable support are used for belt reset.

[0007] Type II hydraulic pump rollers are rotatably connected to both sides of the long side of the movable support, and multiple short rollers are rotatably connected to the outer side of the movable support. Long rollers and anti-rollers are symmetrically rotatably connected to both sides of the movable support.

[0008] The above technical solution further includes:

[0009] The adjustment assembly also includes a lead screw rotatably disposed inside the hydraulic pipe, and a compression thread block threadedly connected to the lead screw is slidably disposed inside the hydraulic pipe. The two sides of the compression thread block are respectively filled with hydraulic oil for raising and lowering the hydraulic rod. The raising and lowering hydraulic rod is connected to the hydraulic pipe.

[0010] The telescopic end of the lifting hydraulic rod is rotatably connected to the movable support with a movable plate. The type I hydraulic pump idler and the type II hydraulic pump idler are equipped with an active flywheel at one end extending to the outside of the movable support.

[0011] A driven flywheel is symmetrically installed at one end of the lead screw extending to the outside of the hydraulic pipe. An electromagnet is installed between the driven flywheel and the lead screw. A belt is sleeved and connected between the driven flywheel and the driving flywheel.

[0012] Limiting rollers are symmetrically installed on the outer side of the movable bracket. The belt slides relative to the limiting rollers. Tightening damping telescopic rods are symmetrically fixedly connected to both sides of the movable plate. The telescopic ends of the tightening damping telescopic rods are fixedly connected to limiting hole plates. The belt passes through the through holes of the limiting hole plates and slides relative to them.

[0013] The top of the fixed bracket is rotatably connected to a rotating shaft, which is fixedly connected to a hydraulic pipe.

[0014] The fixed bracket is rotatably connected to a rotating pin on the side near the type I hydraulic pump roller. A hydraulic cylinder is mounted on the rotating pin, and a connecting block is rotatably connected to the telescopic end of the hydraulic cylinder and the hydraulic pipe.

[0015] An oil supply pipe is provided between the hydraulic cylinder and the hydraulic pipe, and the oil supply pipe and the hydraulic pipe are connected to each other on the side near the I-type hydraulic pump roller.

[0016] This utility model has the following beneficial effects:

[0017] In this invention, when the misaligned conveyor belt touches the hydraulic pump-type idler, the hydraulic pump-type idler rotates with the conveyor belt. The hydraulic system controls the extension and retraction of the hydraulic cylinder rod, which in turn causes the movable support to tilt left and right. At the same time, the extension and retraction of the hydraulic cylinder rod causes the movable support to rotate in the horizontal plane. After rotation, the movable support and the cross-section of the conveyor belt form an angle. As the angle increases, the friction between the idler and the conveyor belt increases. The increased friction prevents the conveyor belt from deviating until the conveyor belt separates from the hydraulic pump-type idler and no longer contacts it, thus achieving the effect of the conveyor belt self-centering and small-radius turning.

[0018] In this invention, the hydraulic system automatically adjusts the material, avoiding manual adjustment and preventing phenomena such as material spillage and tape edge flipping and overlapping. It has the advantages of small turning radius, strong terrain adaptability, and unmanned adjustment. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example

[0031] like Figures 1-9 As shown, this utility model proposes a novel hydraulic automatic adjustment small radius continuous turning device, including a fixed bracket 11 and a movable bracket 12. The fixed bracket 11 is provided with an adjustment component, which includes a hydraulic pipe 19 rotatably mounted on the fixed bracket 11. A lifting hydraulic rod 2 is symmetrically installed between the movable bracket 12 and the fixed bracket 11. The lifting hydraulic rod 2 is used to adjust the tilt angle of the movable bracket 12. The rotation of the hydraulic pipe 19 is used to adjust the rotation angle of the movable bracket 12. The changes in the tilt angle and rotation angle of the movable bracket 12 are used for tape reset.

[0032] Type II hydraulic pump rollers 18 are rotatably connected to both sides of the long side of the movable support 12. Multiple short rollers 13 are rotatably connected to the outer side of the movable support 12. Long rollers 14 and anti-rollers 16 are symmetrically rotatably connected to both sides of the movable support 12.

[0033] The adjustment assembly also includes a lead screw 22 rotatably disposed inside the hydraulic pipe 19. A pressing threaded block 10 threadedly connected to the lead screw 22 is slidably disposed inside the hydraulic pipe 19. Both sides of the pressing threaded block 10 are filled with hydraulic oil for the extension and retraction of the lifting hydraulic rod 2. The lifting hydraulic rod 2 is connected to the hydraulic pipe 19.

[0034] The telescopic end of the lifting hydraulic rod 2 is rotatably connected to the movable support 12 by a movable plate 3. The type I hydraulic pump roller 15 and the type II hydraulic pump roller 18 are equipped with an active flywheel 6 at one end extending to the outside of the movable support 12.

[0035] A driven flywheel 20 is symmetrically installed at one end of the lead screw 22 extending to the outside of the hydraulic pipe 19. An electromagnet 23 is installed between the driven flywheel 20 and the lead screw 22. A belt 1 is sleeved and connected between the driven flywheel 20 and the driving flywheel 6.

[0036] Furthermore, with Figure 1For example, the left side of the Type II hydraulic pump idler roller 18 and the right side of the Type I hydraulic pump idler roller 15 are both examples. The Type I hydraulic pump idler roller 15 is fixed in the slot at the upper right end of the movable bracket 12. Its structure combines a hydraulic pump with a belt conveyor idler roller. When the misaligned conveyor belt touches the Type I hydraulic pump idler roller 15, the Type I hydraulic pump idler roller 15 rotates with the conveyor belt. The rotation of the Type I hydraulic pump idler roller 15 drives the drive flywheel 6 to rotate, and the rotation of the drive flywheel 6 is transmitted through the belt 1. The driven flywheel 20 is driven to rotate. At this time, the electromagnet 23 on one side of the type I hydraulic pump roller 15 is activated, and the electromagnet 23 is engaged with the lead screw 22. At this time, the lead screw 22 rotates. Since the electromagnet 23 on the side near the type II hydraulic pump roller 18 is not activated, the type II hydraulic pump roller 18 will not rotate. At this time, under the rotation of the lead screw 22, the extrusion thread block 10 is driven to move towards the type I hydraulic pump roller 15. At this time, the hydraulic oil in the lifting hydraulic rod 2 on one side of the type I hydraulic pump roller 15 increases. At this time, the right side rises and the left side falls.

[0037] Limiting rollers 7 are symmetrically installed on the outer side of the movable bracket 12. The belt 1 slides relative to the limiting rollers 7. Tightening damping telescopic rods 4 are symmetrically fixedly connected to both sides of the movable plate 3. The telescopic end of the tightening damping telescopic rod 4 is fixedly connected to the limiting hole plate 5. The belt 1 passes through the through hole of the limiting hole plate 5 and slides relative to it.

[0038] Furthermore, during the extension and retraction of the lifting hydraulic rod 2, the angle of the movable plate 3 can be changed. At the same time, the tightening damping telescopic rod 4 moves synchronously with the movable plate 3. During the tilting of the movable bracket 12, the belt 1 needs to be extended or shortened. Therefore, the adjustment is completed by the actual extension or shortening of the tightening damping telescopic rod 4.

[0039] The top of the fixed bracket 11 is rotatably connected to a rotating shaft 8, and the rotating shaft 8 is fixedly connected to the hydraulic pipe 19.

[0040] A rotating pin 9 is rotatably connected to the side of the fixed bracket 11 near the I-type hydraulic pump roller 15. A hydraulic cylinder 17 is mounted on the rotating pin 9. A connecting block 21 is rotatably connected between the telescopic end of the hydraulic cylinder 17 and the hydraulic pipe 19.

[0041] An oil supply pipe is provided between the hydraulic cylinder 17 and the hydraulic pipe 19, and the oil supply pipe and the side of the hydraulic pipe 19 near the type I hydraulic pump roller 15 are connected to each other.

[0042] Furthermore, hydraulic oil on the right side enters the hydraulic cylinder 17, and the hydraulic cylinder 17 extends to drive the movable support 12 to rotate counterclockwise in the horizontal plane. After rotation, the movable support 12 and the cross-section of the conveyor belt form an angle. As the angle increases, the friction between the short idler 13, the long idler 14 and the conveyor belt increases. The increased friction prevents the conveyor belt from deviating until the conveyor belt separates from the type I hydraulic pump idler 15 and no longer contacts it, achieving the self-centering adjustment effect of the conveyor belt.

[0043] Furthermore, such as Figure 8 As shown, the hydraulic automatic adjustment small radius continuous turning device of this utility model includes an upper hydraulic automatic adjustment mechanism 111, a belt conveyor body 222, and a lower idler roller group 333. The upper hydraulic automatic adjustment mechanism 111 is bolted to the belt conveyor body 222. The upper hydraulic automatic adjustment mechanism 111 can automatically adjust in the horizontal plane and around the Z-axis according to the belt deviation, so as to achieve the self-centering adjustment effect of the belt of the belt conveyor.

[0044] Furthermore, the lower idler roller group 333 is fixed to the belt conveyor body 222 by bolts, which serves to support the lower belt. The belt conveyor body 222 is arranged in a small radius arc around the center to achieve the turning effect of the belt conveyor.

[0045] Furthermore, such as Figures 1-7 As shown, the fixed support 11 is fixed to the belt conveyor body 2 by bolts. It is a long crossbeam welded from steel plates and has a supporting function. The movable support 12 is connected to the fixed support 11 through the rotating shaft 8. The movable support 12 can rotate in the horizontal plane and around the Z-axis through the pin. It is welded from steel plates and has a groove-shaped structure with slots on the steel plates.

[0046] Furthermore, the short idler roller 13 is rotatably mounted in the slot of the movable support 12. Its structure is that of a belt conveyor idler roller, with its shaft engaged in the slot in the middle of the movable support 12, serving to support the conveyor belt and provide friction for it. The long idler roller 14 rotates in the slot of the movable support 12. Its structure is that of a belt conveyor idler roller, with its shaft engaged in the slot on the side of the movable support 12, serving to support the conveyor belt and provide friction for it.

[0047] Furthermore, when the misaligned conveyor belt touches the Type II hydraulic pump idler 18, the Type II hydraulic pump idler 18 rotates with the conveyor belt. Consistent with the above principle, the rotation of the Type II hydraulic pump idler 18 drives the threaded block 10 to move in the opposite direction. The hydraulic oil in the lifting hydraulic rod 2 on one side of the Type II hydraulic pump idler 18 increases. At this time, the right end of the movable bracket 12 lowers and the left end rises. At the same time, the hydraulic rod of the hydraulic cylinder 17 retracts. The retraction of the hydraulic rod of the hydraulic cylinder 17 drives the movable bracket 12 to rotate clockwise in the horizontal plane. After rotation, the movable bracket 12 and the cross-section of the conveyor belt form an angle. After the angle increases, the friction between the short idler 13, the long idler 14 and the conveyor belt increases. The increased friction prevents the conveyor belt from deviating until the conveyor belt separates from the Type II hydraulic pump idler 18 and no longer contacts it, achieving the self-centering adjustment effect of the conveyor belt.

[0048] like Figure 9 As shown, the belt conveyor body 2 is arranged around the center in a small-radius arc. The upper hydraulic automatic adjustment mechanism 1 is fixed to the belt conveyor body 2 by bolts. The upper hydraulic automatic adjustment mechanism 1 is perpendicular to the arc and is arranged along the radius towards the center.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
