Detailed description of the invention
As shown in Figure 1,2,3, 4, a kind of block broken belt catcher of the present invention, 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 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 being positioned at the Non-return idler 2 of roller rack 1 both sides all drives and is connected with rotating rotating shaft 12, and rotating shaft 12 is connected with wedging plate 5 by unilateral bearing II 15.Roller rack 1 outside wedging plate 5 arranges two edger rolls 9.Connected 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 be meshed, and center shaft 2-2 and rotating shaft 12 perpendicular, rotating shaft 12 be provided with deep groove ball bearing 16 and thrust baring 19 and be connected on roller rack 1 by bearing seat II 17.Unilateral bearing II 15 is arranged on above rotating shaft 12, and rotating shaft 12 top is 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 outer cover 13 and with the Non-return idler 2 of corresponding side and parallels.Wedging plate 5 comprises upper mounted plate 10 and lower adjustment plate 6, and upper mounted plate 10 one end is connected on outer cover 13, and lower adjustment plate 6 is parallel with upper mounted plate 10 and be bolted in the below of upper mounted plate 10.Roller rack 1 outside wedging plate 5 is provided with wedging plate limiting stopper 8.Self-aligning roller bearing 14 and thrust baring 19 are all the certain axial forces in order to wedging plate can bear.Rotating shaft 12 two ends jam nut 20 is locked, and arranges guard shield 7, play a protective role outside rotating shaft 12.
As shown in Figure 5,6, the end face center, roll body 2-1 two ends of Non-return idler 2 is provided with bearing seat III 2-9 caved inward, center shaft 2-2 is through bearing seat III 2-9 center, unilateral bearing I 2-5 is enclosed within 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 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 center shaft 2-2.Antifriction-bearing box 2-7 is connected on bearing seat I 2-8, and bearing seat I 2-8 can be fixed on roller rack 1.Slipper 2-4 is reverse C shape, and the upper edge lengths of slipper 2-4 is greater than lower edge lengths.Roller rack 1 below Non-return idler 2 is provided with slipper limiting stopper 3, in the draw-in groove between connecting panel 2-3 and unilateral bearing, is provided with seal ring 2-6.
Its principle of work is: when transmission adhesive tape 11 normally runs, as shown in Figure 7, Non-return idler 2 rotates with transmission adhesive tape 11 service direction, due to the reason of unilateral bearing I 2-5, slipper 2-4 is freely on the hand of rotation of Non-return idler 2, and under gravity, slipper 2-4 leans against on slipper limiting stopper 3, owing to there being connecting panel 2-3 to be connected between slipper 2-4 with center shaft 2-2, so center shaft 2-2 is static in this condition; Wedge block plate leans against on wedging plate limiting stopper 8, gets out of the way transmission adhesive tape 11, does not affect the transport of material.
When transmission adhesive tape 11 ruptures or belt takes a turn for the worse, transmission adhesive tape 11 can at self effect inverted running with material gravity, as shown in Figure 8, the hand of rotation of Non-return idler 2 also can be contrary with under nominal situation, owing to can only rotate along a direction to bearing I, center shaft 2-2 can rotate with Non-return idler 2 with slipper 2-4, and by finishing bevel gear cuter 18, the rotation of center shaft 2-2 is passed to rotating shaft 12, rotating shaft 12 drives wedging plate 5 to rotate together by unilateral bearing II 15, along with the rotation of slipper 2-4 and wedging plate 5, gap between them is more and more less, transmission adhesive tape 11 is by between stuck slipper 2-4 and wedging plate 5, complete the catch brake of catcher to transmission adhesive tape 11.As Fig. 9 is mode of operation when transmission adhesive tape 11 stops.
After transmission adhesive tape 11 failture evacuation, when transmission adhesive tape 11 can normally run again, slipper 2-4 can rotate until depart from transmission adhesive tape 11 under the effect of transmission adhesive tape 11 friction force, and finally rests in again the position shown in Fig. 7.Because wedging plate 5 can 12 rotate freely around the shaft on the direction that transmission adhesive tape 11 normally runs, wedging plate 5 can rest in the position shown in Fig. 7 equally under the thrust transmitting adhesive tape 11 friction force or material.Edger roll 9 pairs of adhesive tapes play position-limiting action, can prevent the sideslip of adhesive tape.
The above is only the preferred implementation of this patent; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the art of this patent principle; can also make some improvement and replacement, these improve and replace the protection domain that also should be considered as this patent.
