Abstract
The invention relates to a method for detecting the rolling resistance coefficient of a conveyer belt, which comprises the following steps of: putting a movement roller of a conveyer belt resistance detector at the middle of a sample block to be detected, so that a pendulum bob is vertical and downward; manually rotating the movement roller, so that the outer end of the a starting angle rod of the conveyer belt resistance detector is contacted with the place of the sample; and not controlling the movement roller and recording the time when the pendulum bob stops. The method can detect and compare the rolling resistance coefficient of cover rubber of the conveyer belt to define the energy consumption condition of the conveyer belt in practical service, is simple in operation, and has a more realistic detection result.
Description
Technical field
The present invention relates to a kind of method for detecting rolling resistance coefficient of conveyer belt, belong to the rubber conveyer belt technical field.
Background technology
In the material carrier, the resistance to rolling between conveying belt and the conveyer carrying roller makes induction system can not make full use of the energy, forms the waste of higher degree, increases induction system operating cost.
The conveying belt production industry all is devoted to reduce the research and the experiment of conveying belt resistance to rolling, but does not also have the test detecting instrument of science that the resistance coefficient of rubber (conveying belt) is tested, contrasted at present.
Summary of the invention
The purpose of this invention is to provide a kind of method for detecting rolling resistance coefficient of conveyer belt.This method of testing is based on conveying belt actual motion Design Pattern, the more approaching reality of detection mode and testing result.
The technical scheme that the present invention takes is:
Conveying belt resistance detector comprises the motion roll, and the motion roll connects pendulum by connecting rod, and the motion roll is provided with the beginning angle rod.
Described motion roll and pendulum are cylindrical.
The circular cross section radius of described cylindrical motion roll and cylindrical pendulum equates that the height of cylindrical motion roll is greater than the height of cylindrical pendulum.
Bottom surface and connecting rod that described cylindrical motion roll and cylindrical pendulum are by the one end join.Described connecting rod is the U-shaped steel pole.
Described beginning angle rod is vertical with the plane at connecting rod place.
A kind of method for detecting rolling resistance coefficient of conveyer belt comprises the steps:
(1) prepares an area and be not less than the conveying belt sample to be tested piece of 20cm * 20cm, and place it on the horizontal hard test table top;
(2) the motion roll of conveying belt resistance detector is placed in treats that pendulum vertically downward in the middle of the test sample piece;
(3) the manual time-keeping device is set and is reset to zero;
(4) rotate the motion roll by hand, with the plane contact at the beginning angle rod outer end and the sample place of conveying belt resistance detector;
(5) decontrol the control of hand, be allowed to condition under the effect of plumb-bob gravity and begin swing and opening entry time the motion roll;
Record stand-by time (unit: second S) when (6) treating the stop motion of motion roll; The motion roll will guarantee not to be subjected to the influence of any external force in whole motion process;
(7) duplicate detection, log is also done contrast.
By measuring run duration (resistance coefficient, the unit: second), with this determine conveyer belt cover glue be in operation to the resistance size of belt idler, weigh the degree of power conservation of conveying belt of motion roll at conveyor belt surface.
The invention has the beneficial effects as follows: can detect contrast conveyer belt cover rubber-surfaced roll dynamic resistance coefficient, determine conveying belt consumption situation to the energy in actual motion with this, simple to operate, the more approaching reality of testing result.

Embodiment
Conveying belt resistance detector comprises motion roll 1, and motion roll 1 connects pendulum 3 by connecting rod 2, and motion roll 1 is provided with beginning angle rod 4.
Beginning angle rod 4 is common steel poles, requires hardness to want high, not yielding, and is vertical with the plane at connecting rod place;
Pendulum 3 is with motion roll 1 identical cross-section, highly is its cylindrical steel rider of 1/4th;
Connecting rod 2 is U-shaped steel poles, works to connect motion roll and pendulum.
Bottom surface and connecting rod that cylindrical motion roll and cylindrical pendulum are by the one end join.
A kind of method for detecting rolling resistance coefficient of conveyer belt comprises the steps:
(1) prepares an area and be not less than conveying belt or the film for rubber sample piece of 20cm * 20cm, and place it on the horizontal hard test table top;
(2) the motion roll of conveying belt resistance detector is placed in treats that pendulum is (see figure 3) vertically downward in the middle of the test sample piece;
(3) the manual time-keeping device is set and is reset to zero;
(4) rotate the motion roll by hand, with the plane contact (see figure 4) at the beginning angle rod outer end and the sample place of conveying belt resistance detector;
(5) decontrol the control of hand, be allowed to condition under the effect of plumb-bob gravity and begin swing and opening entry time the motion roll;
Record stand-by time (unit: second S) when (6) treating the stop motion of motion roll; The motion roll will guarantee not to be subjected to the influence of any external force in whole motion process;
(7) duplicate detection, log is also done contrast.
By measuring the motion roll at the run duration of conveyor belt surface (resistance coefficient, unit: second), with this determine that conveyer belt cover glue is in operation and belt idler between the resistance size, the degree of power conservation of measurement conveying belt.
