Description

Technical Field

[0001] The present application relates to the field of equipment detection and inspection, and in particular to an online detection system and method for dynamic load of a tank rope. Background Art

[0002] At present, the tankways used in mine shaft hoisting mainly include rigid tankways (combined steel tankways, rail tankways, and wooden tankways) and flexible tankways. Rigid tankways have the disadvantages of large material consumption, long construction time, and high maintenance costs; flexible tankways use tankway ropes as guide devices for hoisting containers. Compared with rigid tankways, flexible tankways have simple structures, stable and reliable high-speed operation, save steel, are easy to install, reduce the labor intensity of installers, reduce shaft operations, and improve the working environment.

[0003] Wire rope tankway is also called flexible tankway. Compared with rigid tankway shaft equipment, it has the advantages of simple design, steel saving, reduced investment, quick installation, stable operation, long service life, easy maintenance and replacement, and small ventilation resistance. Although the wire rope tankway has the disadvantages of large container operation swing, larger shaft section relative to the rigid tankway, increased load on the derrick due to the tensioning force of the tankway rope, and deeper water pit at the bottom of the well when the heavy hammer is used for tensioning, it has outstanding advantages. Therefore, it is widely used in the vertical shaft hoisting of small and medium-sized mines. Wire rope tankway is suitable for single-rope and multi-rope hoisting, and the shaft depth can reach more than one kilometer. Wire rope tankway mainly uses sealed and semi-sealed wire ropes. Ordinary wire ropes are less used due to their non-wear resistance and are only suitable for shallow wells and temporary cage hoisting shafts. The layout of the wire rope tankway in the wellbore mainly includes four-rope symmetrical layout at four corners, four-rope single-side layout, two-rope diagonal layout, three-rope triangular layout, etc. (the above refers to a single container), which can be used for single-system and dual-system lifting, and multiple systems can also be arranged in the same well with rigid tankway well equipment. The tensioning methods of the wire rope tankway mainly include two forms: bottom-hole weight tensioning and top-hole (derrick) hydraulic tensioning.

[0004] The weight tensioning method is to fix the upper part of the tankway rope and use a weight to tighten it underground. The advantages are simple structure, easy manufacturing and installation, and the required tensioning force can be achieved by adjusting the number of weight blocks. However, there are also many disadvantages. In addition to requiring a large amount of cast iron and digging a deeper water pit at the bottom of the well, it is also necessary to equip a multi-layer metal structure, which increases the installation time and labor intensity, and makes maintenance, inspection and observation difficult. Moreover, as debris accumulates in the water pit, it is easy to silt up the weight tensioning device, reduce the tension force at the rope end, reduce the rigidity coefficient of the rope tankway, and cause the tankway rope to move, posing a serious threat to safety lifting. Based on this, how to realize tankway rope load detection has become a technical problem that needs to be solved in this field. Summary of the invention

Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] In an exemplary embodiment, the present application provides an online detection system for dynamic load of a tank rope, such as Figure 1 As shown, the system includes: a tank rope load sensing device and a wire rope tension detection device. Among them, the model of the wire rope tension detection device can be ZJA12.

[0034] The tankway rope load sensing device is wirelessly connected to the wire rope tension detection device.

[0035] The tankway rope load sensing device is used to obtain the weight information of the tankway rope. The wire rope tension detection device is used to obtain the dynamic detection result of the tankway rope load based on the weight information of the tankway rope. The dynamic detection result of the tankway rope load includes the early warning information of the tankway rope load and the dangerous fault information. The wire rope tension detection device is also used to obtain the fault reasoning result based on the weight information of the tankway rope after obtaining the dangerous fault information. For example, the difference in the internal and external tensioning force of the tankway rope exceeds the limit, that is, there is a skew in the bucket, and the tank ears and sliding tank ears are damaged. The force on a single tankway rope increases suddenly, that is, there are loose strands in the tankway rope or the bucket shakes violently during operation. The force on a single tankway rope decreases sharply, that is, there is a break in the tankway rope or the weight falls off.

[0036] In actual application, if the weight of the tank rope is 8t (tons), the weight is 12-14t, and the total is 20-24t. The sensor uploads the weight information in real time. If it is 8t, it means the weight has fallen off. If the weight is less than 1t, it means the tank rope has broken and fallen off.

[0037] In another exemplary embodiment of the present application, Figure 1 As shown, the tank rope load sensing device includes a sensing unit and an inspection platform.

[0038] The sensing unit is electrically connected to the inspection platform. The inspection platform is wirelessly connected to the wire rope tension detection device. The sensing unit is used to obtain the weight information of the tankway rope. The inspection platform is used to wirelessly transmit the weight information of the tankway rope to the wire rope tension detection device.

[0039] The sensing unit includes multiple sensors. All of the multiple sensors are connected to the maintenance platform through cables. All of the multiple sensors are strain gauge pressure sensors. For example, a sensor model GZD20 is used, with an input power supply of 8-30V, a collection pressure of 0-50t, and an output current signal of 4mA-20mA.

[0040] In another exemplary embodiment of the present application, in order to allow the overall weight of the tankway rope to act on the sensor to improve the detection accuracy of the weight information, in this embodiment, a rope locking device may be further provided in the tankway rope dynamic load online detection system provided by the present application. The rope locking device is used to allow the weight of the tankway rope to act on the sensor unit.

[0041] In another exemplary embodiment of the present application, in order to realize wireless transmission of information, as a preferred implementation scheme, in this embodiment, Figure 1 As shown, a signal transmitter can be arranged in the maintenance platform, and a signal receiver matching the signal transmitter can be arranged in the wire rope tension detection device.

[0042] Another exemplary embodiment of the present application uses the online detection system for dynamic load of tankway rope provided by the present application for detection, and takes the control of the tankway rope as an example to illustrate the specific working principle of the online detection system for dynamic load of tankway rope provided by the present application.

[0043] When the weight of the tank rope acts on the sensor, the resistance of the strain gauge changes to obtain the corresponding weight value. The weight signal is collected and converted into a 4mA-20mA current signal through analog conversion. The current signal is wirelessly transmitted to the wire rope tension detection device through the maintenance platform. The software data is analyzed and screened by the wire rope tension detection device, and the abnormal information is transmitted to the winch room. Through the program compilation of the industrial control computer in the winch room, the abnormal alarm is realized to lock the hoist operation.

[0044] In actual application, the wire rope tension detection device is embedded with computer control software, and its judgment principle is:

[0045] By presetting the initial values ​​of normal operation and parking conditions, the force condition and current signal of the sensor under normal conditions are limited to a certain range. During the online detection of the dynamic load of the tankway rope, if the weight information of the tankway rope detected exceeds the normal load range and does not exceed ±10%, it is in the early warning range. At this time, the signal will be transmitted to the hoist electronic control and a warning signal will be issued. When the collected weight information of the tankway rope exceeds the normal load range by ±10%, it is a dangerous fault signal. At this time, the signal will be transmitted to the hoist electronic control and a danger signal will be issued. The hoist electronic control will synchronously lock the hoist operation, quickly weaken the danger signal and notify relevant personnel to go to the site to check the operation of the tankway rope.

[0046] Based on the above description, the operation condition of the hoisting rope can be checked from the side through the change of the rope load. At the same time, the tension of the rope can be dynamically adjusted according to the force conditions to improve the stability of operation and meet the application specifications of the corresponding industry. For example, Article 6.4.4.6 of the "Safety Regulations for Metal and Non-metal Mines" GB16423-2020 stipulates: "The tension of the rope of each hoisting container should differ by 5%-10%, with greater tension on the inside and less tension on the outside."

[0052] Step 103: When the weight information of the tank rope is in the fault range, dangerous fault information is generated.

[0053] Step 104: After obtaining the dangerous fault information, obtain the fault inference result based on the weight information of the tank rope.

[0054] As an optional implementation, the warning interval is exceeding the set load range with a lower limit value not exceeding -n% of the set load range and an upper limit value not exceeding +n% of the set load range, wherein n=10.
