[0040] like Figures 1-6 As shown, this embodiment is implemented through the following technical solutions: a drilling rig derrick 1 is set on a platform 2, a support beam 4 is provided at the bottom of the platform 2, and a support module 3 for maintaining its own balance is also provided on one side of the platform 2; a piezoresistor 15 is provided at the connection of the steel beam of the drilling rig derrick 1, an alarm device is provided on the outer shell of the piezoresistor 15, the piezoresistor 15 is connected to the alarm trigger circuit, and the alarm trigger circuit and the alarm device are connected to the alarm control circuit.

[0041] Specifically, the alarm device includes an alarm light 11 and an alarm bell 10 connected in parallel.

[0042] Specifically, the alarm trigger circuit includes: a comparator 9, a first auxiliary power supply 5, a second auxiliary power supply 6, an electronic ammeter 7 and a variable resistor 8. One end of the piezoresistor 15 is connected to the first auxiliary power supply 5, and the other end is grounded through the electronic ammeter 7. The analog signal output end of the electronic ammeter 7 is connected to an input end of the comparator 9. One end of the variable resistor 8 is connected to the second auxiliary power supply 6, and the other end of the variable resistor 8 is grounded. The adjustment end of the variable resistor 8 is connected to the other input end of the comparator 9, and the signal output end of the comparator 9 is connected to the alarm control circuit.

[0043] Specifically, the alarm control circuit includes a first relay 14, a second relay 12, and a release switch. The comparator's signal output is connected to the negative DC power supply via the coil of the first relay 14. The first normally open contact of the first relay 14 has one end connected to the negative power supply via the coil of the first relay 14, and the other end connected to the positive power supply via the normally closed contact of the second relay 12. The coil of the second relay 12 has one end connected to the positive DC power supply via the release switch 13, and the other end connected to the negative DC power supply. The power supply terminals of the alarm light 11 and alarm bell 10 are connected to the DC power supply via the second normally open contact of the first relay 14.

[0044] The platform 2 includes a detection platform 201, under which a first telescopic cylinder 205 and a second telescopic cylinder 206 are provided. A clamping seat 202 and a pressing seat 203 are slidably connected to the detection platform 201; the clamping seat 202 and the pressing seat 203 are respectively connected to the output ends of the first telescopic cylinder 205 and the second telescopic cylinder 206.

[0045] In this embodiment, the first telescopic cylinder 205 and the second telescopic cylinder 206 are arranged in pairs and are both double-acting hydraulic cylinders. Two clamping seats 202 are provided on the single first telescopic cylinder 205, and the moving trajectories of the clamping seats 202 between the first telescopic cylinders 205 are parallel; similarly, two pressing seats 203 are provided on the single second telescopic cylinder 206, and the moving trajectories of the pressing seats 203 between the second telescopic cylinders 206 are parallel; the first telescopic cylinder 205 and the second telescopic cylinder 206 are both arranged close to the edge of the detection platform 201, such as Figure 3 shown.

[0046] Specifically, a plurality of level sensors 204 are provided on the testing platform 201 , and the level sensors 204 are close to the edge of the testing platform 201 .

[0047] Specifically, a working window 2011 for assisting the drilling rig derrick 1 in drilling is provided on the inspection platform 201 ; the drilling tool of the drilling rig derrick 1 is moved toward the ground through the working window 2011 .

[0048] Specifically, the pressing seat 203 includes a support arm 2031 , an elastic pile 2032 is provided on the support arm 2031 , and a pressure sensor 2033 is provided at the end of the elastic pile 2032 .

[0049] Specifically, the support beam 4 is set below the testing platform 201; the support beam 4 includes a main beam 401, and an anchor seat 402 is provided at the bottom of the main beam 401. When the platform 2 is installed, the anchor seat 402 is embedded in the ground to enhance the grip of the support beam 4 and ensure that the testing platform 201 is more firmly fixed to the ground.

[0050] Specifically, the support module 3 is set to the side of the detection platform 201; the type of the support module 3 is a hydraulic support leg, and the number of the support modules 3 set is at least 4.

[0051] The specific operating principle of this device is as follows:

[0052] The first telescopic cylinder 205 drives the clamping seat 202 to fit one side of the drilling rig derrick 1 to achieve preliminary positioning of the drilling rig derrick 1. Furthermore, the second telescopic cylinder 206 drives the clamping seat 203 to clamp the other side of the drilling rig derrick 1. The elastic pile 2032 elastically presses the drilling rig derrick 1. When the pressing force reaches the set value of the pressure sensor 2033, the second telescopic cylinder 206 stops moving; at this time, the drilling rig derrick 1 is fixedly connected to the platform 2; after the platform 2 is installed to the construction position, the hydraulic legs of the support module 3 are unfolded, and the support module 3 fine-tunes the inclination of the platform 2. The horizontal sensor 204 assists in leveling the platform 2.

[0053] The resistance value of the piezoresistor 15 will change according to the stress change at the steel beam connection. The voltage of the first auxiliary power supply 5 is fixed. As the resistance value changes, the current value of the electronic ammeter 7 will also change, and the output analog signal representing the current will also change. When the connection of the steel structure of the drilling rig derrick 1 is loose, the stress on the corresponding piezoresistor 15 will decrease, and the resistance value of the piezoresistor 15 will decrease accordingly. The corresponding current value will increase, and the voltage corresponding to the analog signal will also increase. When the voltage at the input end of the comparator 9 corresponding to the electronic ammeter 7 is greater than the voltage at the input end of the comparator connected to the variable resistor 8, the comparator 9 outputs a signal.

[0054] The function of the variable resistor 8 is to adjust the voltage of the first input terminal of the comparator 9. In order for the present application to adapt to the drilling rig derrick 1 with different stress standards, a variable resistor 8 is set for adjustment to adjust the voltage value of the first input terminal of the comparator 9, that is, the output threshold of the comparator 9, thereby improving the adaptability of the present application.

[0055] After the comparator 9 outputs a signal, the coil of the first relay 14 is energized, and the normally open contact of the first relay 14 is closed, so that the coil of the first relay 14 remains connected to the power supply, and the normally open contact of the first relay 14 remains closed. The closure of the normally open contact of the first relay 14 causes the alarm light 11 and the alarm bell 10 to start working and start the alarm. After the on-site staff, especially the staff responsible for safety, learn about it, they can use their own authority to press the release switch 13. The release switch 13 is a non-self-locking switch. After pressing the release switch 13, the coil of the second relay 12 is energized, the normally closed contact of the second relay 12 is disconnected, the path between the first relay 14 and the DC power supply is disconnected, the coil of the first relay 14 loses power, and the normally open contact of the first relay 14 is disconnected, and the alarm light 11 and the alarm bell 10 lose power and stop working.

[0056] Of course, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of the embodiments of the present invention. The present invention is not limited to the above examples. Equivalent changes and improvements made by ordinary technicians in this technical field within the essential scope of the present invention should all fall within the scope of the patent of the present invention.
