[0044] Please refer to Figures 1-3 The application is a kind of weighing system for pipeline cable rotary table,

[0045] The rotary table 1 is provided with the weighing idler 2 on the bottom surface, and the weighing idler 2 is evenly distributed along the diameter of the rotary table 1, and each circle is provided with a plurality of weighing idlers 2 arranged in an annular array.

[0046] The weighing idler 2 comprises an idler 21, a cantilever beam sensor 22 and a base 23, the idler 21 is arranged on the bottom surface of the rotary table 1, the bottom surface of the idler 21 is provided with the cantilever beam sensor 22, the cantilever beam sensor 22 is installed on the base 23, and the base 23 is a square plate structure.

[0047] The cantilever beam sensor 22 is installed at the four right angles of the base 23 in an array manner.

[0048] The application can monitor the real-time weight of the rotary table when winding the cable, and avoid the phenomenon of overloading of the rotary table, thereby ensuring the safety of the rotary table.

[0049] Embodiment 2

[0050] The application of the weighing system for pipeline cable rotary table comprises the following contents:

[0051] The acquisition module acquires the real-time weight data of the rotary table when winding the cable;

[0052] Since the weighing idlers are evenly distributed along the rotary table, the weighing value Zc ij of each weighing idler is acquired, wherein i represents the number of turns, j represents the number of each turn, i = 1, 2, 3... n, j = 1, 2, 3... m, n and m are positive integers;

[0053] The monitoring module acquires the weighing value Zc ij of each weighing idler of the acquisition module; ij The weighing values Zc of all the weighing idlers are added to obtain the cable weight value Gx;

[0054] The obtained cable weight value Gx is compared with the cable weight threshold value;

[0055] If the cable weight value Gx is greater than the cable weight threshold value, it indicates that the weight of the cable wound on the rotary table is too large and exceeds the carrying range of the rotary table, and a stop signal is generated;

[0056] If the cable weight value Gx is less than the cable weight threshold, it means that the weight of the cable being wound on the turntable is too small and does not exceed the turntable's bearing capacity. The winding work can continue and a winding signal will be generated.

[0057] The cable weight threshold is set by technicians based on actual production, and the cable weight threshold is preferably no more than 8-10% of the actual standard load capacity of the turntable.

[0058] The weighing roller of this invention acquires real-time cable weighing data and performs real-time calculation and analysis on the weighing data to achieve real-time online monitoring during the turntable winding process, avoiding overload when the turntable is wrapped, which could lead to the risk of turntable failure.

[0059] The storage module acquires the weighing value Zc of each weighing roller from the acquisition module. ij The cable weight value Gx of the monitoring module is saved;

[0060] The storage module of this invention allows for the traceability of historical winding data of the symmetrical load-bearing roller, facilitating analysis and judgment based on the data, and determining the working status of the turntable.

[0061] The analysis module obtains the weighing value Zc from the storage module. ij， Analyze the working status of the turntable;

[0062] The specific working process of this analysis module is as follows:

[0063] Step 1: Obtain the cable weight value Gx during the cable winding period, and compare the obtained cable weight value Gx with the cable weight range; this cable weight range is obtained by technicians based on the cable quality.

[0064] If the cable weight value Gx is greater than the cable weight range, it indicates that the cable weight wound at that time point is too heavy; or if the cable weight value Gx is less than the cable weight range, it indicates that the cable weight wound at that time point is too light, and a cable defect signal is generated accordingly.

[0065] If the cable weight value Gx is within the cable weight range, it indicates that the quality of the wound cable is qualified, and a cable qualification signal is generated.

[0066] Step 2: Obtain the weighing value Zc for each weighing roller. ij First, the weighing value Zc of each rotation of the weighing roller is recorded. ij By summing the values, we can obtain the weight Zc per revolution of the turntable. i ;

[0067] The formula CGq = |Zc1-Zc2| + |Zc2-Zc3| + ... + |Zc i-1 -Zc i|, the disc surface weight difference value CGp is calculated;

[0068] The disc surface weight difference value CGp obtained is compared with a disc surface weight difference threshold value;

[0069] If the disc surface weight difference value CGp is greater than the disc surface weight difference threshold value, it indicates that the overall force of the rotating disc is uneven, and a first check signal is generated;

[0070] If the disc surface weight difference value CGp is less than the disc surface weight difference threshold value, it indicates that the overall force of the rotating disc is even, and a rotating disc overall qualified signal is generated;

[0071] Step 3: Obtain the weighing value Zc of each weighing trolley ij , the ring level weight difference value CGq is calculated through the formula CGq = |Zc i1 -Zc i2 |+|Zc i2 -Zc i3 |+...+|Zc ij-1 -Zc iij |, the disc surface weight difference value CGp is calculated;

[0072] The disc surface weight difference value CGp obtained is compared with a disc surface weight difference threshold value;

[0073] If the disc surface weight difference value CGp is greater than the disc surface weight difference threshold value, it indicates that the overall force of the rotating disc is uneven, and a first check signal is generated;

[0074] If the disc surface weight difference value CGp is less than the disc surface weight difference threshold value, it indicates that the overall force of the rotating disc is even, and a rotating disc overall qualified signal is generated;

[0075] The alarm module obtains the cable unqualified signal, the first check signal and the second check signal of the analysis module, when the cable unqualified signal is obtained, an alarm is sent out, and the quality of a certain section of cable is displayed on the display screen, when the first check signal and the second check signal are obtained, an alarm is sent out, and the rotating disc and the weighing trolley are checked;

[0076] The analysis module of the application can judge the quality of the cable and the rotating disc or the weighing trolley according to the data obtained by the weighing trolley, and can alarm and overhaul in real time for the existing faults by sequentially passing through the time node, the overall and local weighing changes.

[0077] The working principle of the application is as follows: the application sets the weighing trolley 2, which can monitor the rotating disc in real time when winding the cable, to avoid the phenomenon of rotating disc overload, and to ensure the safety of the rotating disc.

[0078] And the invention is called weighing the towing wheel 2, the real-time cable weighing data is obtained, and the real-time calculation and analysis of the weighing data is carried out, the real-time online monitoring in the winding process of the rotating disc is achieved, the phenomenon of overload when the rotating disc is wound is avoided, the risk of the rotating disc existing fault is caused, the historical winding data of the weighing supporting wheel can be traced, the working state of the rotating disc is convenient for analyzing and judging according to the data, and the data obtained by the weighing supporting wheel is sequentially through the time node, the overall and local weighing change, the mass of the cable and the rotating disc or the weighing supporting wheel can be judged, and the existing fault can be alarmed and repaired in real time.
