Problems solved by technology

When cutting the conveyor belt sample on a long strip, whether it is mechanical cutting or heating cutting, the physical properties of the position close to the cutting section will change, which will change the adhesion between the various parts inside the conveyor belt sample. Internal stress, and can be manifested by tension changes, the smaller the axial length of the conveyor belt sample, the larger the proportion of the affected area to the total size of the sample, the more obvious this effect, so the test results will obviously deviate from the actual Numerical values, the indicators of the new conveyor belt designed with reference to the test results will also deviate from the expected results

Embodiment 1

[0073] Embodiment 1: see Figure 1 to Figure 9 and Figure 24 .

[0074] A conveyor belt troughability test device, including 5 sets of trough idler rollers arranged along the direction Z of the conveyor belt sample 5, each trough idler set includes 5 idler rollers 6, two of which are side supports rollers, the rest are intermediate rollers, the size and position of the troughed rollers are exactly the same as those on the corresponding troughed belt conveyors, by image 3 and Figure 4 It can be seen that the axis line of each idler 6 is perpendicular to the direction Z of the conveyor belt sample 5, can translate along the direction Z of the conveyor belt sample 5, and can translate and rotate in a section perpendicular to the direction. The rollers are set in such a way that they can be flexibly adjusted and replaced, so as to adapt to various specifications and models of trough roller sets and conveyor belt samples 5; The idler seat 2 or the forward-inclining roller se...

Embodiment 2

[0087] Embodiment 2: A kind of conveyor belt troughability test method and device, see Figure 9 to Figure 19 .

[0088] The combination of one group of mechanical arms and the lifting mechanism is installed on a large carriage assembly 14, and the large carriage assembly 14 is connected with the base assembly 12 through a moving pair. The moving pair is a linear guide rail pair, a slide block 14-1 is installed on the large carriage assembly 14, and a linear guide rail 12-1 is installed on the base assembly 12, and the two form a linear guide rail pair.

[0089] For the combination of multiple groups of mechanical arms and lifting mechanisms described above, three groups are provided in this embodiment.

[0090] The combination of each group of mechanical arms and lifting mechanism described above includes 2 large mechanical arms 15, 2 small mechanical arms 17 and a lifting mechanism 13. The lifting mechanism 13 is installed in the middle of the large pallet assembly 14 by sc...

Embodiment 3

[0109] Embodiment 3: A kind of conveyer belt grooving test device, see Figure 20 to Figure 21 .

[0110] The specification of the idler 6 used in this embodiment is φ89x200 mm, and the width of the tested conveyor belt sample 5 is 650 mm. Each trough-shaped idler group includes 4 idlers 6, and the axes of the two side idlers 6 On a plane, the angle between the horizontal plane and the horizontal plane is 60°, installed on two large mechanical arms 15, the axis lines of the two middle rollers 6 are on the same plane, and the axis line is 25° from the horizontal plane, Be installed on two small mechanical arms 17. The elevating mechanism 13 is not idle, and the handwheel 13-8 is rotated so that the elevating frame 13-1 is in a relatively low position, so that other mechanisms can not be hindered from working.

[0111] Other structures, functions and operation methods are the same as in Embodiment 2.

Abstract

The invention discloses a conveyer belt troughability test method and apparatus. The apparatus comprises multiple trough carrying roller groups arranged along the direction of a conveyer belt sample, each trough carrying roller group comprises three to five carrying rollers, two of the five carrying rollers are edge carrying rollers, and the other three are middle carrying rollers, the axis of each carrying roller is vertical to the direction of the conveyer belt sample, and each carrying roller, under the driving of a supporting frame, can translate along the direction of the conveyer belt sample and can also translate and rotate in a plane vertical to the direction; the carrying rollers are connected with carrying roller seats, and the carrying roller seats are connected with the signal input ends of sensors; and the signal output ends of the sensors are connected with a signal conditioning and data acquisition facility, and the signal conditioning and data acquisition facility communicates with a computer. According to the invention, the test results are closer to actual conditions, the description is more meticulous, and the method and apparatus have quite important guidance significance on design and production.

Description

technical field [0001] The invention belongs to the technical field of conveyor belt detection, and relates to a method and a device for testing the transverse troughability of a conveyor belt for a troughed belt conveyor, and in particular to a method and a device for testing the troughability of a conveyor belt. Background technique [0002] Belt conveyors are widely used in all walks of life in national production, and play an irreplaceable role in social development. Some are used to transport bulk materials, and some are used to transport finished items. They can either run continuously or Cooperating with the technological process in the production process, a rhythmic assembly line is formed, which can transport powder, small particles, and small block materials, as well as medium particle size and large block materials, and can even transport particles with a particle size of more than 600mm. For materials, the operating environment is generally -20°C to +40°C. There ...
