Abstract
The utility model discloses a test device for testing the running stop coefficient of a supporting roll set of a ribbon conveyer. Four air cushion disks 1 are used for supporting the supporting roll set 2, both sides of the supporting roll set 1 are provided with the air cushion disks 6 to overcome the lateral sideslip force of a ribbon belt; after the air cushion disks are ventilated to form air cushions, the entire supporting roll set can float freely; when the ribbon belt 8 runs, a supporting roll 9 is rotated by friction, and then the supporting roll set moves forward to touch onto a front sensor 7 to measure the running resistance; simultaneously, four sensors 5 arranged below the air cushion disks 1 detect the corresponding vertical load, the ratio of the two measurement values is the coefficient of running resistance. The utility model has the advantages of small additional resistance, absorption of shock and high measurement precision, and besides, the utility model is also applicable for the tests of similar continuous conveyers.
Description
The utility model is a kind of resistance coefficients test unit of testing belt conveyor list group carrying roller group.Resistance coefficients is a significant coefficient that calculates belt conveyor complete machine power.Particularly concerning the horizontal belt conveyor of long distance, high capacity, high belt speed, its size directly influences power consumption.Because it requires under the dynamic operation condition of the adhesive tape elastic component of high-speed cruising, the load that is hit and bulk cargo complex deformation carrying roller group running resistance and corresponding vertical load to be tested, record accurately, be the comparison difficulty.
The suspension type test unit of the mechanical fulcrum of known employing has plenty of and surveys many group carrying roller groups, and structure is huge, just is being not easy levelling, has crookedly slightly, will cause bigger additional drag, and it is big to measure data error; Though the survey that has is single group carrying roller group, also be just to be not easy levelling, particularly can not offset additional drag and vibration, directly influence measuring accuracy, also have no way of various carrying rollers are carried out the quality contrast from dynamic impulsion, rubber belt from deviating, the crooked caused all directions of structure.
The utility model proposes the high carrying roller group resistance coefficients test unit of precision.It is contained in the below of carrying adhesive tape 8.Tested carrying roller group 1 is by four air cushion dish 2 supporting, by 4 of ball seats 3, base plate on four fixed sensing 5.Two gas dish 6 are contained in carrying roller group two sides in addition, in order to overcome the horizontal sideslip power of adhesive tape.After the air cushion dish passed to certain air pressure formation air cushion, whole carrying roller group was in complete floating state, moves freely.When the adhesive tape operation was passed through it, carrying roller 9 was by the friction rotation, and the carrying roller group also moves forward thereupon, contacts with two sensors 7 that are fixed on the front, records running resistance, and meanwhile, four following sensors 5 are measured the vertical load of correspondence.Running resistance is resistance coefficients with corresponding vertical load ratio.Because additional drag is minimum, and absorbing, the measuring accuracy height.This device precision can reach 5g.Wherein accompanying drawing is:
Fig. 1: the front view of resistance coefficients test unit.
Fig. 2: the side view of resistance coefficients test unit.
Fig. 3: the vertical view of resistance coefficients test unit.
Claims (2)
1, belt conveyor carrying roller group resistance coefficients test unit, it includes: the supporting of air cushion dish, it almost only transmits vertical force, also has force cell and movable plate.It is characterized in that a carrying roller group 1 by 2 supportings of four air cushion dish, is equipped with four sensors 5 by base plate 4, in its lower section in order to measure vertical load.Be provided with two air cushion dish 6 in addition in carrying roller group two sides, in order to overcome adhesive tape 8 horizontal sideslip power.After ventilation formed air cushion, the carrying roller group was freely floating.During the adhesive tape operation, tested carrying roller 9 is by the friction rotation, and carrying roller group 1 moves forward with the sensor 7 that is fixed on the front and contacts simultaneously, measures running resistance.
2, by the belt conveyor carrying roller group resistance coefficients test unit of claim 1, it is characterized in that air cushion dish 2 movably connects by ball seat 3 with following sensor 5, form an operation higher pair.
