Description

[0002] With the overcapacity of steel and the increasingly fierce market competition, higher requirements are put forward for the control of the production rhythm in the hot-rolled strip steel production line. After the hot-rolled strip steel is coiled into a coil by a coiler, the steel coil is placed on the carriage of the coil transfer car and transported to the steel coil storage by the steel coil transportation track, and then lifted into the storage by a crane. The wheels of the carriage of the coil transfer car run on the steel coil transportation track. Since the wheels of the carriage are in direct contact with the wear-resistant pads on the transportation track, after a long time, the wear-resistant pads on the transportation track are worn. Due to the different positions of the steel coils placed on the carriage, the wear amounts of the wear-resistant pads on both sides of the transportation track are inconsistent. If the wear amounts on both sides are too large, it is easy to cause the steel coil to overturn, affecting the continuity of production. Summary of the Invention

[0040] The present invention will be further described in detail below in conjunction with the drawings and embodiments.

[0041] The embodiment of the present invention provides an on-line detection method for the wear amount of the wear-resistant backing plate of the hot-rolled strip steel coil transportation track, which is applied to a detection system. The detection system includes a flexible film pressure sensor, a wear-resistant backing plate and a transportation track. The flexible film pressure sensor is arranged between the transportation track and the wear-resistant backing plate; as Figure 1 shown, the method includes:

[0042] Step 101: When the steel coil trolley carrying the steel coil passes through the wear-resistant backing plate, detect the pressure change of the wear-resistant backing plate through the flexible film pressure sensor to obtain the pressure data of the wear-resistant backing plate on the storage area side and the pressure data of the wear-resistant backing plate on the rolling line side;

[0043] Step 102: Calculate the average pressure of the wear-resistant backing plate on the storage area side and the average pressure of the wear-resistant backing plate on the rolling line side according to the pressure data of the wear-resistant backing plate on the storage area side and the pressure data of the wear-resistant backing plate on the rolling line side;

[0044] Step 103: Obtain the steel coil shape parameters, steel coil trolley equipment parameters, transportation track equipment parameters and flexible film pressure sensor parameters; according to the steel coil shape parameters, the steel coil trolley equipment parameters, the transportation track equipment parameters, the flexible film pressure sensor parameters, the average pressure of the wear-resistant backing plate on the storage area side and the average pressure of the wear-resistant backing plate on the rolling line side, calculate the force arms of the wear-resistant backing plate on the storage area side and the wear-resistant backing plate on the rolling line side;

[0045] Step 104: Determine the relative wear amount of the wear-resistant backing plate on the storage area side and the wear-resistant backing plate on the rolling line side according to the lever arms of the wear-resistant backing plate on the storage area side and the wear-resistant backing plate on the rolling line side.

[0046] In this embodiment, data such as the width of the steel coil, the diameter of the steel coil, and the width of the transport track are obtained; the change in the pressure value during the operation of the steel coil trolley is obtained through the flexible film pressure sensor between the wear-resistant backing plate and the transport track; the average pressures of the wear-resistant backing plates on both sides of the transport track are calculated respectively; and the wear amounts of the wear-resistant backing plates on both sides are calculated according to the determination method. The on-line detection method for the wear amount of the wear-resistant backing plate of the hot-rolled strip steel coil transport track proposed in this embodiment can provide an effective basis for avoiding the steel coil overturning accident.

[0047] In this embodiment, the width of the flexible film pressure sensor needs to be less than or equal to the contact width between the wear-resistant backing plate and the wheels of the steel coil trolley. Multiple flexible film pressure sensors of the same specification can be arranged in the length direction of the wear-resistant backing plate, and the number of flexible film pressure sensors can be selected according to the actual situation.

[0048] Specifically, according to the pressure data of the wear-resistant backing plate on the storage area side and the pressure data of the wear-resistant backing plate on the rolling line side, the following calculation formula can be used to calculate the average pressure of the wear-resistant backing plate on the storage area side and the average pressure of the wear-resistant backing plate on the rolling line side:

[0050] Among them, is the average pressure of the wear-resistant backing plate on the storage area side, is the average pressure of the wear-resistant backing plate on the rolling line side, n is the number of flexible film pressure sensors arranged on the wear-resistant backing plate on the storage area side; m is the number of flexible film pressure sensors arranged on the wear-resistant backing plate on the rolling line side; P max,i is the maximum value in the pressure data of the wear-resistant backing plate on the storage area side collected by the i-th flexible film pressure sensor during the period when the steel coil trolley passes through the wear-resistant backing plate, P max,j is the maximum value in the average pressure of the wear-resistant backing plate on the rolling line side collected by the j-th flexible film pressure sensor during the period when the steel coil trolley passes through the wear-resistant backing plate.

[0051] In this embodiment, the flexible thin-film pressure sensor is placed between the transportation track and the wear-resistant backing plate, and the wear-resistant backing plate can be fixed to the transportation track by bolts. The flexible thin-film pressure sensor in this embodiment can be connected to a pressure data acquisition server. When the coil car carrying the steel coil passes through the wear-resistant backing plate, the flexible thin-film pressure sensor detects the pressure change transmitted by the wear-resistant backing plate, and obtains the pressure data P1 of the wear-resistant backing plate on the storage area side and the pressure data P2 of the wear-resistant backing plate on the rolling line side. That is, when the coil car carrying the steel coil just touches the wear-resistant backing plate, the flexible thin-film pressure sensor starts to detect the pressure value transmitted by the wear-resistant backing plate and transmits the pressure data to the server, and the server processes and stores the collected pressure data. After the coil car passes through the wear-resistant backing plate, the flexible thin-film pressure sensor stops detecting the pressure value transmitted by the wear-resistant backing plate, and finally obtains the pressure data P1 of the wear-resistant backing plate on the storage area side and the pressure data P2 of the wear-resistant backing plate on the rolling line side.

[0052] The steel coil form parameters in this embodiment include the steel coil width, the outer diameter of the steel coil, and the inner diameter of the steel coil. The coil car equipment parameters include the gravity of the coil car. The transportation track equipment parameters include the transportation track width. The flexible thin-film pressure sensor parameters include the contact area of the flexible thin-film pressure sensor of the wear-resistant backing plate on the storage area side and the contact area of the flexible thin-film pressure sensor of the wear-resistant backing plate on the rolling line side.

[0053] In one embodiment, according to the steel coil form parameters, the coil car equipment parameters, the transportation track equipment parameters, the flexible thin-film pressure sensor parameters, the average pressure of the wear-resistant backing plate on the storage area side, and the average pressure of the wear-resistant backing plate on the rolling line side, the lever arms of the wear-resistant backing plate on the storage area side and the wear-resistant backing plate on the rolling line side can be calculated using the following calculation formula:

[0054]

[0055] where l1 is the lever arm of the wear-resistant backing plate on the storage area side, l2 is the lever arm of the wear-resistant backing plate on the rolling line side, P1 is the average pressure of the wear-resistant backing plate on the storage area side, is the average pressure of the wear-resistant backing plate on the rolling line side; S1 is the contact area of the flexible thin-film pressure sensor of the wear-resistant backing plate on the storage area side, S2 is the contact area of the flexible thin-film pressure sensor of the wear-resistant backing plate on the rolling line side, b is the transportation track width, G is the sum of the gravity G1 of the steel coil and the gravity G2 of the coil car; where the expression of G1 is:

[0056] G1 = π×ρ×g×B×[(D / 2) 2 -(d / 2) 2

[0057] where D is the outer diameter of the steel coil, d is the inner diameter of the steel coil, B is the steel coil width, and g is the acceleration due to gravity.

[0058] ​In addition, according to the lever arms of the wear-resistant backing plate on the storage area side and the wear-resistant backing plate on the rolling line side, the relative wear amounts of the wear-resistant backing plate on the storage area side and the wear-resistant backing plate on the rolling line side can be determined in the following manner, including:

[0059] When the average pressure of the wear-resistant backing plate on the storage area side is greater than the average pressure of the wear-resistant backing plate on the rolling line side, the wear amount of the wear-resistant backing plate on the storage area side relative to the wear-resistant backing plate on the rolling line side is:

[0060]

[0061] When the average pressure of the wear-resistant backing plate on the storage area side is less than the average pressure of the wear-resistant backing plate on the rolling line side, the wear amount of the wear-resistant backing plate on the storage area side relative to the wear-resistant backing plate on the rolling line side is:

[0062]

[0063] When the average pressure of the wear-resistant backing plate on the storage area side is equal to the average pressure of the wear-resistant backing plate on the rolling line side, the wear amount of the wear-resistant backing plate on the storage area side relative to the wear-resistant backing plate on the rolling line side is:

[0064] △3 = 0

[0065] Wherein, l1 is the lever arm of the wear-resistant backing plate on the storage area side, l2 is the lever arm of the wear-resistant backing plate on the rolling line side, and l is the distance between the wear-resistant backing plate on the storage area side and the wear-resistant backing plate on the rolling line side.

[0066] Here, S1 and S2 are the contact areas of the flexible film pressure sensors of the wear-resistant backing plates on the storage area side and the rolling line side respectively. The calculation method is S1 = n × S0, S1 = m × S0; n is the number of flexible film pressure sensors arranged on the wear-resistant backing plate on the storage area side; m is the number of flexible film pressure sensors arranged on the wear-resistant backing plate on the rolling line side, and S0 is the contact area of one flexible film pressure sensor.

[0067] An on-line detection method for the wear amount of the wear-resistant backing plate of the hot-rolled strip steel coil transportation track proposed in this embodiment can on-line detect the wear amounts on both sides of the wear-resistant backing plate of the transportation track, which can effectively guide equipment maintenance and avoid the accident of the steel coil tipping over.
