Fig. 2 is a force curve diagram of a bolt.
Fig. 3 is a force curve diagram of the bolt.
The specific implementation mode is as follows:
the invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, a torque detection internet of things cloud service system comprises a control host 2, a monitoring platform 3, a hydraulic wrench 1 with a torque display function and a wireless communication module, wherein the hydraulic wrench 1 performs data transmission with the control host 2 through the wireless communication module, and the control host 2 performs data transmission with the monitoring platform 3 through the wireless communication module. The control host machine 2 records the number of the screwed bolts of the hydraulic wrench 1 and generates a stress curve graph of each screwed bolt.
The use method of the torque detection internet of things cloud service system is described in detail below.
The invention discloses a torque detection Internet of things cloud service method, which comprises the following steps:
1) before the hydraulic wrench is used, hydraulic wrenches required by a construction market are numbered one by one, and then the number information of each hydraulic wrench and the maximum torque of the hydraulic wrench are input into a control host.
2) The bolts are classified according to the tightening torque values of the bolts at the construction site, for example, 1000N · m bolts are classified, 1500N · m bolts are classified, and 2000N · m bolts are classified. And numbering the classified bolts, and inputting the numbering information of the bolts and the number of all the bolts in each numbering catalog into the control host. And then selecting a hydraulic wrench with a proper number according to the classified bolt tightening torque value, so that the hydraulic wrench with one number is matched with the bolt with one number.
For example, when the hydraulic wrench numbered 1 fastens 4 bolts numbered 1000N · m and numbered a, the hydraulic wrench numbered 1 is matched with the bolt numbered a in advance on the control master, and then the total number of the bolts numbered a, that is, 4 bolts is input in the control master.
3) Setting three gradually increased grabbing values for the hydraulic wrench with the corresponding number according to the matched tightening torque value of the bolt, setting pressure maintaining time after each grabbing value, and finishing bolt fastening after the hydraulic wrench tightens the bolt and exceeds the pressure maintaining time of the maximum grabbing value;
when the hydraulic wrench with the number 1 is used for fastening a bolt with the number of 1000N · m, three gripping values of the hydraulic wrench with the number 1 are respectively set to 300N · m, 600N · m and 1000N · m, a pressure holding time of 3s is respectively set after 300N · m and 600N · m, and a pressure holding time of at least 10s is set after 1000N · m.
4) When a hydraulic wrench with the number of 1 screws 4 bolts with the number of 1000N · m, the hydraulic wrench rotates all the bolts one by one three times in order to ensure balanced stress of the bolts. That is, the hydraulic wrench numbered 1 rotates all the bolts to 300N · m and maintains the pressure for 3s one by one for the first time, rotates all the bolts to 600N · m and maintains the pressure for 3s one by one for the second time, and rotates all the bolts to 1000N · m and maintains the pressure for 10s one by one for the third time, thereby completing the fastening of the bolts.
When screwing, whether the hydraulic wrench reaches the maximum grabbing value and completes the pressure maintaining time is monitored to judge whether the bolt is screwed in place by a worker, so that the operation process of the worker is standardized. After the hydraulic wrench finishes fastening one bolt, the control host machine displays that the bolt fastening is finished under the A bolt number catalog.
It should be noted that, in order to avoid overlapping the number of records on the control host caused by repeated fastening of the bolts, in the actual operation process, a worker fastens one bolt, and the fastened bolt needs to be marked by marking. The number of the bolts input on the host is controlled so as to better monitor the work of workers and avoid the phenomenon that the workers have nonstandard operation flows and the bolts are fastened in a leakage manner.
In the process of screwing the bolts by the hydraulic wrench, the hydraulic wrench displays the output torque of screwing each bolt in real time, transmits the torque output by screwing each bolt to the control host, generates a corresponding stress curve graph (shown in figure 2) of the hydraulic wrench screwing according to the received output torque, and marks three grabbing values of screwing each bolt and the pressure maintaining time after the three grabbing values on the stress curve graph.
According to fig. 2, in the process that the hydraulic wrench with the number of 1 screws 4 bolts with the number of A, after the hydraulic wrench is opened, the hydraulic wrench displays the output torque in real time. After the hydraulic wrench rotates 4 bolts to 300 N.m one by one for the first time and maintains the pressure for 3s, the stress curve graph captures the first pressure maintaining time of the four bolts. In actual operation, there may be a case of work interruption, that is, during screwing the bolt, a worker may temporarily interrupt the rotation of the bolt, and when the bolt does not reach the pressure maintaining value set by the hydraulic wrench, the bolt is displayed as a state on the force diagram, and when the bolt is rotated again, the force curve of the bolt is regenerated after the curve of the state a.
When the 4 bolts are rotated one by one for the second time, if one bolt does not reach 300N · m in the first rotation process, and after the 4 bolts are directly rotated to 600N · m for the second time, a case where one bolt does not reach the holding pressure in the first rotation process is shown in the figure (the bolt in the state of the a curve in fig. 3 does not reach 300N · m). Therefore, according to the force diagram, whether each bolt rotates according to the standard requirement can be intuitively observed, and then the overhaul condition of workers is standardized and monitored.
When the torque of the hydraulic wrench reaches 300N · m, 600N · m and 1000N · m, three grasping values are marked for each bolt, and the hydraulic wrench is held at 300N · m for 3s, 600N · m for 3s and 1000N · m for 10 s. Whether the pressure maintaining time of the hydraulic wrench at 1000 N.m exceeds 10s is observed to monitor whether the bolt is screwed in place by a worker, so that the operation flow of the worker is standardized.
5) The control host stores the monitored bolt stress curve, the pressure maintaining time and the data of the fastening bolt to the local or uploads the data to the cloud through the network, and the data are displayed through the background monitoring platform. The condition of an overhaul or operation and maintenance team is judged in an auxiliary mode through parameters such as the torque value, the fastening quantity and the pressure maintaining time of the bolts in real time, monitoring parameters support upper and lower limit alarming, operation and maintenance personnel are assisted to find problems in the bolt fastening process in time, and maintenance departments can be guided to process and prevent potential safety hazards in time to prevent the problems in the bud.
Meanwhile, a GPS positioning module is arranged on each control host, and the background monitoring platform displays the position of each control host in real time.
The hydraulic wrench disclosed by the invention is a hydraulic wrench with a digital display component, which is produced by our company, and the patent number is CN201920801471.0, and communication modules are additionally arranged on the hydraulic wrench and a control host machine so as to realize wireless data transmission between the hydraulic wrench and the control host machine.
The foregoing is only a preferred embodiment of this invention and it should be noted that modifications can be made by those skilled in the art without departing from the principle of the invention and these modifications should also be considered as the protection scope of the invention.
