[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0039] Example 1

[0040] Embodiment 1 of the present invention provides a belt conveyor belt tension testing system, comprising a support 4, a pressure sensor 2 and a trigger member; the support 4 and the pressure sensor 2 are arranged on the frame 1 of the belt conveyor, and the support 4 is connected to the rotary support mechanism 6 of the roller in the belt conveyor; one end of the trigger member is connected to the support 4, and the other end is used to trigger the pressure sensor 2.

[0041] Figure 1 This is a specific example of the use of the belt tension test system of the belt conveyor in Example 1 of the present invention. Figure 1 As shown, the belt tension test system of the belt conveyor is installed at the position where the belt 5 changes its direction. Figure 1In the figure, the redirecting roller 3, the support 4 and the pressure sensor 2 are all arranged on the frame 1 of the belt conveyor, the support 4 is bolted to the slewing support mechanism 6 (such as a bearing seat) of the redirecting roller 3 on the belt conveyor, one end of the triggering member (such as a triggering rod) is hinged to the support 4, and the other end is used to trigger the pressure sensor 2.

[0042] Figure 2 This is another specific example of the use of the belt tension test system of the belt conveyor in Embodiment 1 of the present invention. Figure 2 As shown, the belt tension test system of the belt conveyor is installed near the driving roller 7. Figure 2 In the embodiment, the direction of the adhesive tape 5 near the driving roller 7 is changed by the redirecting roller 3. Figure 2 As shown, the redirecting roller 3, the support 4 and the pressure sensor 2 are all arranged on the frame 1 of the belt conveyor, the support 4 is bolted to the slewing support mechanism 6 (such as a bearing seat) of the redirecting roller 3 on the belt conveyor, one end of the triggering member (such as a triggering rod) is hinged to the support 4, and the other end is used to trigger the pressure sensor 2.

[0043] The belt conveyor belt tension testing system provided in Example 1 of the present invention includes a support 4, a pressure sensor 2 and a trigger member. When the belt conveyor is running, the force is transmitted to the pressure sensor 2 through the slewing support mechanism 6, the support 4 and the trigger member, and the pressure is detected by the pressure sensor 2, so that the tension of the belt conveyor belt 5 can be further obtained according to the pressure detected by the pressure sensor 2 through the torque balance principle. The belt conveyor belt tension testing system provided in the embodiment of the present invention has a simple structure, is easy to operate, and its position in the belt conveyor can be reasonably adjusted according to actual conditions.

[0044] Example 2

[0045] Embodiment 2 of the present invention provides a belt conveyor belt tension testing method, which is applied to the belt conveyor belt tension testing system of embodiment 1 of the present invention. Figure 3 As shown, the belt conveyor belt tension test method of embodiment 2 of the present invention comprises the following steps:

[0046] S301: Obtain the gravity of the drum and the pressure detected by the pressure sensor respectively.

[0047] Corresponding to the belt conveyor belt tension testing system of Example 1 of the present invention, in Example 2 of the present invention, the gravity of the roller refers to the gravity of the redirecting roller.

[0048] S302: Calculate the resultant tension force of the tape by using the pressure and gravity based on the moment balance relationship among the pressure, gravity and the resultant tension force of the tape.

[0049] As a specific implementation manner, the following technical scheme can be adopted to calculate the resultant tension force of the tape by utilizing the pressure and the gravity based on the torque balance relationship among the pressure, the gravity and the resultant tension force of the tape: respectively obtain the force arm from the position of the pressure sensor to the resultant tension force of the tape, the force arm from the position of the pressure sensor to the gravity of the roller, and the force arm from the position of the pressure sensor to the pressure detected by the pressure sensor; input the pressure, the gravity, the force arm from the position of the pressure sensor to the resultant tension force of the tape, the force arm from the position of the pressure sensor to the gravity of the roller, and the force arm from the position of the pressure sensor to the pressure detected by the pressure sensor into a preset torque balance relationship to obtain the resultant tension force of the tape.

[0050] More specifically, the moment balance equation is: the moment of the pressure = the moment of the resultant force of the tape tension + the moment of the drum weight. The moment of the pressure is the product of the pressure and the arm from the location of the pressure sensor to the pressure detected by the pressure sensor; the moment of the resultant force of the tape tension is the product of the resultant force of the tape tension and the arm from the location of the pressure sensor to the resultant force of the tape tension; the moment of the drum weight is the product of the gravity of the drum and the arm from the location of the pressure sensor to the drum weight.

[0051] In the embodiment of the present invention, the moment of pressure is equal to the vector sum of the moment of the resultant force of the tape tension and the moment of the drum gravity.

[0052] Specifically, corresponding to Figure 1 , the pressure detected by the pressure sensor × the force arm from the position of the pressure sensor to the pressure detected by the pressure sensor = the resultant force of the tension of the tape × the force arm from the position of the pressure sensor to the resultant force of the tension of the tape + the gravity of the roller × the force arm from the position of the pressure sensor to the gravity of the roller.

[0053] Corresponds to Figure 2 , the pressure detected by the pressure sensor × the force arm from the position of the pressure sensor to the pressure detected by the pressure sensor = the resultant force of the tension of the tape × the force arm from the position of the pressure sensor to the resultant force of the tension of the tape - the gravity of the roller × the force arm from the position of the pressure sensor to the gravity of the roller.

[0054] In the above moment balance equation, only the resultant force of the tape tension is an unknown quantity, so the resultant force of the tape tension can be obtained using the above moment balance equation. Specifically, in Embodiment 2 of the present invention, the force arm from the position of the pressure sensor to the drum gravity can be obtained based on the position information of the pressure sensor and the direction of the drum gravity; the force arm from the position of the pressure sensor to the pressure detected by the pressure sensor can be obtained based on the position information of the pressure sensor and the direction of the pressure detected by the pressure sensor.

[0055] The force arm from the position of the pressure sensor to the resultant force of the tape tension is obtained by the following method: obtaining the direction of the first tension and the direction of the second tension at both ends of the roller; obtaining the direction of the resultant force of the tape tension according to the direction of the first tension and the direction of the second tension; obtaining the position information of the position of the pressure sensor; obtaining the force arm from the position of the pressure sensor to the resultant force of the tape tension according to the position information of the position of the pressure sensor and the direction of the resultant force of the tape tension. In Embodiment 2 of the present invention, the magnitude of the first tension is equal to the magnitude of the second tension, so the direction of the resultant force of the tape tension can be obtained according to the direction of the first tension and the direction of the second tension.

[0056] S303: Decomposing the tension force of the adhesive tape to obtain the tension of the adhesive tape.

[0057] In Embodiment 2 of the present invention, the directions of the first tension and the second tension at both ends of the roller are known, and the resultant tension of the tape is also known, so the resultant tension of the tape can be decomposed to obtain the tension of the tape. The decomposition of the resultant tension of the tape can be carried out in any manner in the prior art, and the embodiment of the present invention is not limited thereto.

[0058] The belt conveyor belt tension testing method provided in Example 2 of the present invention obtains the pressure detected by the pressure sensor and the gravity of the drum respectively, and calculates the resultant tension force of the belt based on the torque balance relationship between the pressure, the gravity and the resultant force of the belt tension; finally, the tension of the belt is obtained by decomposing the resultant tension force of the belt. With the above technical solution, the tension of the belt can be obtained only by obtaining the gravity of the drum and the pressure detected by the pressure sensor, and the method is simple and easy to operate. At the same time, the obtained belt tension is fed back, so that the belt operation status can be timely understood, which helps to find problems in time, and can also adjust the power of each driving motor of the belt conveyor to reduce operating costs.

[0061] Specifically, the acquisition module 40 is used to respectively acquire the pressure detected by the pressure sensor and the gravity of the drum.

[0062] The calculation module 42 is used to calculate the resultant tension force of the tape by using the pressure and the gravity based on the moment balance relationship among the pressure, the gravity and the resultant tension force of the tape.
