The specific embodiment
Shown in Fig. 1,2,3,4, a kind of Catcher for broken belt device of the present utility model, comprise roller rack 1, roller rack 1 is provided with three Non-return idlers 2, Non-return idler 2 comprises roll body 2-1 and center shaft 2-2, center shaft 2-2 is horizontally through roll body 2-1 center and is rotatably connected on the roller rack 1, and center shaft 2-2 is connected with slipper 2-4, and roll body 2-1 is connected with center shaft 2-2 by unilateral bearing I 2-5; The center shaft 2-2 outer end that is positioned at the Non-return idler 2 of roller rack 1 both sides all drives and is connected with rotating rotating shaft 12, is connected with wedging plate 5 by unilateral bearing II 15 in the rotating shaft 12.The roller rack 1 in wedging plate 5 outsides arranges two edger rolls 9.Connect by universal coupling 4 between three Non-return idlers 2.
The center shaft 2-2 outer end of both sides Non-return idler 2 and rotating shaft 12 are provided with the finishing bevel gear cuter 18 that is meshed, and center shaft 2-2 and rotating shaft 12 are perpendicular, and rotating shaft 12 is provided with deep groove ball bearing 16 and thrust baring 19 and is connected on the roller rack 1 by bearing seat II 17.Unilateral bearing II 15 is arranged on rotating shaft 12 tops, and rotating shaft 12 tops are provided with self-aligning roller bearing 14, and unilateral bearing II 15 and self-aligning roller bearing 14 are connected with outer cover 13 jointly, and wedging plate 5 is connected on the outer cover 13 and with the Non-return idler 2 of respective side and parallels.Wedging plate 5 comprises upper mounted plate 10 and adjusts plate 6 down, and upper mounted plate 10 1 ends are connected on the outer cover 13, and following plate 6 and the upper mounted plate 10 adjusted is parallel and be connected the below of upper mounted plate 10 by bolt.The roller rack 1 in wedging plate 5 outsides is provided with wedging plate limiting stopper 8.Self-aligning roller bearing 14 and thrust baring 19 all are certain axial forces that can bear for the wedging plate.Lock with jam nut 20 at rotating shaft 12 two ends, outside the rotating shaft 12 guard shield 7 is set, and plays a protective role.
Shown in Fig. 5,6, the end face center, roll body 2-1 two ends of Non-return idler 2 is provided with the bearing seat III 2-9 that caves inward, center shaft 2-2 passes bearing seat III 2-9 center, unilateral bearing I 2-5 is enclosed within on the center shaft 2-2, the inner ring key of unilateral bearing I 2-5 connects center shaft 2-2, and the outer ring of unilateral bearing I 2-5 is connected in the bearing seat III 2-9.The two ends of center shaft 2-2 are provided with connecting panel 2-3 and antifriction-bearing box 2-7, and connecting panel 2-3 is connected with slipper 2-4, and connecting panel 2-3 key is connected on the center shaft 2-2.Antifriction-bearing box 2-7 is connected on the bearing seat I 2-8, and bearing seat I 2-8 can be fixed on the roller rack 1.Slipper 2-4 is reverse C shape, and the last edge lengths of slipper 2-4 is greater than following edge lengths.The roller rack 1 of Non-return idler 2 belows is provided with slipper limiting stopper 3, is provided with seal ring 2-6 in the draw-in groove between connecting panel 2-3 and the unilateral bearing.
Its principle of work is: during transmission adhesive tape 11 normal operations, as shown in Figure 7, Non-return idler 2 is with the rotation of transmission adhesive tape 11 service directions, reason owing to unilateral bearing I 2-5, slipper 2-4 is freely at the hand of rotation of Non-return idler 2, and under the effect of gravity, slipper 2-4 leans against on the slipper limiting stopper 3, owing to have connecting panel 2-3 to be connected between slipper 2-4 and the center shaft 2-2, so center shaft 2-2 is static under this state; The wedge block plate leans against on the wedging plate limiting stopper 8, gets out of the way transmission adhesive tape 11, does not influence the transportation of material.
When the fracture of transmission adhesive tape 11 or belt take a turn for the worse, transmission adhesive tape 11 can be at the effect inverted running of self and material gravity, as shown in Figure 8, the hand of rotation of Non-return idler 2 also can with nominal situation under opposite, because can only be along a direction rotation to the bearing I, center shaft 2-2 and slipper 2-4 can rotate with Non-return idler 2, and by finishing bevel gear cuter 18 rotation of center shaft 2-2 is passed to rotating shaft 12, rotating shaft 12 drives wedging plate 5 by unilateral bearing II 15 and rotates together, rotation along with slipper 2-4 and wedging plate 5, gap between them is more and more littler, transmission adhesive tape 11 is finished catcher to the braking of arresting of transmission adhesive tape 11 with between stuck slipper 2-4 and the wedging plate 5.Be transmission adhesive tape 11 mode of operation when stopping as Fig. 9.
After the eliminating of transmission adhesive tape 11 faults, when transmission adhesive tape 11 can normally move again, slipper 2-4 can rotation transmit adhesive tape 11 until breaking away under the effect of transmission adhesive tape 11 friction force, and finally rests in position shown in Figure 7 again.Because wedging plate 5 12 directions in the 11 normal operations of transmission adhesive tape around the shaft rotates freely, wedging plate 5 can rest in position shown in Figure 7 equally under the thrust of transmission adhesive tape 11 friction force or material.9 pairs of adhesive tapes of edger roll play position-limiting action, can prevent the sideslip of adhesive tape.
The above only is the preferred implementation of this patent; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the art of this patent principle; can also make some improvement and replacement, these improvement and replacement also should be considered as the protection domain of this patent.
