Description

TECHNICAL FIELD

[0001] The present application relates to a testing device, in particular to a tubular belt transverse rigidity testing device. BACKGROUND

[0002] With the development of industrial production, and the development trend of environmental protection and energy saving, the traditional transportation operation mode of many materials has the problems of low efficiency, difficult safety management, dust flying, serious road damage and the like. The tubular belt conveying system has become a relatively prominent and advantageous solution because of its site-specific erection mode and closed and environmentally friendly conveying mode.

[0003] The advantages and disadvantages of the tubular conveying belt have a crucial influence on the one-time investment, energy saving, stability and safety of the system. In addition to the conventional performance such as the strength and wear resistance of the conveying belt, the transverse rigidity thereof has a direct influence on the tubular property (risk of pipe collapse) and long-term operation stability of the product. Moreover, this performance is closely related to the product structure and formula design, and has an influence of more than 10% on the production and operation cost of the product. Therefore, the attention to the transverse rigidity testing of the product is also increasingly prominent in the design of the design unit and the use of the user.

[0004] The existing rigidity testing device for the tubular belt mostly uses a single hexagonal frame to erect the tubular belt sample. Such a loading device has a relatively single function and only has one erection structure. In addition, due to the limitation of the structure, the length of the sample that can be measured is generally between 75 mm and 150 mm, and the pipe diameter of the sample is below 600 mm, so that the applicability and functionality of the loading device are relatively limited. SUMMARY

[0005] The technical problem to be solved by the present application is to provide a tubular belt transverse rigidity testing device in view of the various technical defects of the existing tubular belt testing device.

[0006] To solve the above technical problems, the present application provides a tubular belt transverse rigidity testing device, which comprises a base, a longitudinal moving guide rail arranged on the base, a transverse moving guide rail arranged on the longitudinal moving guide rail, a connecting plate arranged on the transverse moving guide rail, a tubular belt frame, the bottom of the tubular belt frame being rotatably connected with the connecting plate, a sliding groove being arranged on the side surface of the tubular belt frame, a carrier roller penetrating through the side surface of the tubular belt frame and being connected with the tubular belt frame, and a thrust cylinder penetrating through the tubular belt frame and being connected with the carrier roller.

[0007] In the tubular belt transverse rigidity testing device provided by the present application, the bottom of the transverse moving guide rail can be arranged on the longitudinal moving guide rail through a fixing plate, and the fixing plate is slidably connected with the longitudinal moving guide rail.

[0008] In the tubular belt transverse rigidity testing device, the bottom of the tubular belt frame is provided with two arc-shaped sliding grooves at two ends respectively, the arc-shaped sliding groove at one end is fixedly connected with the connecting plate, and the arc-shaped sliding groove at the other end is slidably connected with the connecting plate.

[0009] In the tubular belt transverse rigidity testing device, the number of the sliding grooves is three, the tubular belt frame is a hexagonal structure, and the three sliding grooves are arranged on three sides of the tubular belt frame in a manner of being arranged alternately.

[0012] In the tubular belt transverse rigidity testing device, three supporting rollers are located on one side of the tubular belt frame, and the other three supporting rollers are located on the other side of the tubular belt frame.

[0013] In the tubular belt transverse rigidity testing device, the number of the transverse moving guide rails is at least three, and the number of the tubular belt frames corresponds to the number of the transverse moving guide rails.

[0014] In the tubular belt transverse rigidity testing device, the distance between any two tubular belt frames is 1m-3m, and the transverse displacement of the tubular belt frame at the middle position is 0mm-100mm.

[0015] In the tubular belt transverse rigidity testing device, the supporting rollers are driven by the thrust cylinder to move along the center line of the tubular belt frame.

[0016] The tubular belt transverse rigidity testing device has the following advantages:

[0021] In addition, by arranging at least three groups of transverse moving guide rails, the length of the tubular belt sample can be directly increased from 75-150mm in the prior art to 75-6000mm, so as to guarantee the multi-point detection of the sample and the accuracy of the detection.

[0022] Moreover, the distance between any two pipe belt frames is 1m-3m, and the lateral displacement of the pipe belt frame at the middle is 0mm-100mm. The distance range and displacement range can be adjusted according to the requirements of different samples to be detected, thereby verifying the influence factors of different pipe diameters on the lateral stiffness of the pipe belt under different spacing and different turning radius conditions.

One is that the six supporting rollers are on the same side of the pipe belt frame, and the other is that three supporting rollers are on one side of the pipe belt frame and three supporting rollers are on the other side of the pipe belt frame. Through the sliding grooves on the sides of the pipe belt frame, the convenient switching of the single-side six-supporting-roller and the double-side 3+3-supporting-roller of the test device is realized.

[0047] In addition, the number of the transverse movement guide rails is at least three, and the number of the pipe belt frames matches the number of the transverse movement guide rails, so that three groups of pipe belt frames can be arranged, six feedback sites are formed on each group of six supporting rollers, and at least three groups of pipe belt frames can form more than 18 feedback sites, which can more accurately reflect the influence of different material loading states on the transverse rigidity.

[0048] In addition, by arranging at least three groups of transverse movement guide rails, the length of the pipe belt sample can be directly increased from 75-150 mm in the prior art to 75-6000 mm, which guarantees multi-point detection of the sample and the accuracy of the detection.
