Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of stress monitoring, in particular to a novel grating drilling stress monitoring device. Background Art
[0002] Stress is the force applied to an object, and strain is the deformation rate produced by the force. By testing the strain, we can know the force and deformation of the object. For each material, stress and strain are related, and there is also a certain safety range. Excessive stress will cause structural damage and irreversible deformation.
[0003] Currently, when using a stress tester to monitor the drilling stress of an object, it is usually necessary to place the monitored sample on the stress tester for monitoring, and the sample needs to be fixed by a clamping device during monitoring. However, the existing monitoring device does not have the function of quickly fixing the sample, which makes it easy for data deviation to occur during monitoring. At the same time, when the stress exceeds the range that the sample can withstand, the device cannot automatically shut down the drilling device and automatically sound an alarm, which makes it easy to miss the best closing time, increasing the probability of sample damage, and leading to the problem of low practicality.
[0004] Therefore, those skilled in the art provide a novel grating drilling stress monitoring device to solve the problems raised in the above background technology. Utility Model Content

The drilling machine 205 is electrically connected to the controller 201 through a wire. A wireless communication module 10 is fixedly installed on the left side of the controller 201, and the wireless communication module 10 is electrically connected to the controller 201 through a wire. By setting up the wireless communication module 10, the collected stress data can be sent to the back-end administrator through wireless communication technology under the control of the controller 201.
[0027] The clamping mechanism 3 includes four limit columns 301, the bottom surface of each limit column 301 is fixedly connected to the upper surface of the support plate 1, and the outer surface of each limit column 301 is slidably connected to the inner wall of the lifting plate 204. A switch button 11 is fixedly installed on the front of the stress tester body 203, and the switch button 11 is electrically connected to the stress tester body 203 through a wire. By setting the switch button 11, the efficiency of opening and closing the stress tester body 203 can be further improved, thereby increasing the utilization efficiency of the device.
[0028] The outer surface of each group of limit columns 301 is fixedly connected to a fixing plate 302, the inner wall of each fixing plate 302 is threadedly connected to a first threaded rod 303, the ends of the two first threaded rods 303 that are close to each other are fixedly connected to a bearing 306, and the ends of the two first threaded rods 303 that are away from each other are fixedly connected to a handle 6.

The first threaded rod 303 can move its position when it rotates. Under the action of the movement of the first threaded rod 303, the two groups of clamping plates 304 and the anti-slip pads 305 are driven to move in a direction close to each other until the test sample is clamped and fixed, and then the switch button is pressed. Button 11 turns on the stress tester body 203, and turns on the controller 201 and the drilling machine 205 at the same time. After the drilling machine 205 is turned on, it starts to generate power rotation, and then the staff rotates the second threaded rod 8. The rotation of the second threaded rod 8 can drive the lifting plate 204 to move downward, so that the sample can be drilled with the cooperation of the lifting plate 204 and the drilling machine 205. Under the action of the stress tester body 203, the stress condition of the sample during drilling can be monitored, and the monitored data can be sent to the controller 201 for operation. The controller 201 can send the data to the display screen 9 for display. At the same time, when the controller 201 determines that the stress exceeds the range that the sample can withstand, the controller 201 will control the alarm 202 to sound an alarm, and at the same time will control the drilling machine 205 to be closed, so as to prevent the sample from being damaged.
