Description

Technical Field

[0001] The utility model relates to the technical field of geothermal drilling, in particular to a protective device for construction. Background Art

[0002] During geothermal drilling, the primary function of casing is to protect the borehole wall, prevent it from collapsing, and ensure smooth drilling. Especially in complex formations, casing can effectively protect the wall and plug leaks, ensuring the normal progress of drilling.

[0003] Currently, due to the height difference between the casing construction platform and the ground, a guide plate is generally used to assist in raising the casing. Once the casing is released from the guide plate, it will wobble, requiring workers to assist and support it before lowering it. Existing workers must wait for the casing's wobble to subside before they can begin lowering it. This is time-consuming, reduces the efficiency of casing lowering, and poses a significant safety hazard to workers on the construction platform. Therefore, a construction protective device is proposed. Utility Model Content

[0009] Furthermore, the two fixed side plates are symmetrically rotatably sleeved on the outer surface of the screw body, and the fixed side plates have a supporting effect on the screw body, which is beneficial to the installation of the screw body.

[0011] Furthermore, the inflation component includes an inflation air pump, and the inflation air pump is fixedly installed at the bottom of the door frame. An air supply pipe is fixedly passed through the output end of the inflation air pump, and a connecting pipe is fixedly passed through the end of the air supply pipe.

[0025] A telescopic door frame is installed on the top of the slide 8, and the movable end of the telescopic door frame is fixedly connected to the arc seat 7. The telescopic door frame includes two fixed sleeve rods 6, and the two fixed sleeve rods 6 are symmetrically fixed on the top of the slide 8. The tops of the two fixed sleeve rods 6 are jointly slidably inserted with a door frame 4, and the door frame 4 and the arc seat 7 are fixedly connected.

[0026] An arc-shaped airbag 5 is fixedly embedded on the inner surface of the arc-shaped seat 7, and an inflation component is jointly installed between the arc-shaped airbag 5 and the telescopic door frame. The inflation component includes an inflation air pump 11. The function of the inflation air pump 11 is to provide gas, and the inflation air pump 11 is fixedly installed at the bottom of the door frame 4. The output end of the inflation air pump 11 is fixedly penetrated with an air supply pipe 12, and the end of the air supply pipe 12 is fixedly penetrated with a connecting pipe 13, and the connecting pipe 13 is fixedly installed at the bottom of the arc-shaped seat 7 and connected to the arc-shaped airbag 5. The connecting pipe 13 and the fixed pipe 10 are both fixedly installed with an electromagnetic valve 15. The electromagnetic valve 15 is a prior art, and its model and specifications can be selected according to actual needs. Its function is to control the opening and closing of the connecting pipe 13 and the fixed pipe 10.

[0027] A fixing tube 10 is fixedly connected to the top of the arc-shaped seat 7 , and the fixing tube 10 is communicated with the arc-shaped airbag 5 .

[0028] A gas pressure sensor 14 is fixedly installed on one side of the bottom of the arc-shaped seat 7. The detection end of the gas pressure sensor 14 passes through the inner side of the arc-shaped airbag 5. The gas pressure sensor 14 is an existing technology.

During operation, as the casing gradually rises, the air pump 11 fills air into the arc-shaped airbag 5 through the air supply pipe 12 and the connecting pipe 13. As the amount of gas increases, the arc-shaped airbag 5 gradually expands. When the gas pressure sensor 14 detects that the pressure value reaches the set value, the air pump 11 stops running, and at the same time, the solenoid valve 15 in the connecting pipe 13 controls the connecting pipe 13 to be closed; when the bottom of the casing is separated from the guide plate, it will move to the side of the arc seat 7 under the action of gravity until it hits the arc-shaped airbag 5, and the arc-shaped airbag 5 wraps it to prevent it from shaking. , and then the external lowering device continues to drive the top of the casing to rise, thereby driving the bottom of the casing to rise, and the door frame 4 rises under the action of the arc seat 7 and the arc airbag 5. Then the motor 2 drives the screw body 9 to rotate, and the screw body 9 drives the slide 8 to move toward the center of the tube release. The slide 8 drives the arc airbag 5 and the bottom of the casing to move toward the center of the tube release through the telescopic door frame. At the same time, the solenoid valve 15 controls the fixed pipe 10 to open, and the gas in the arc airbag 5 is discharged. It is closed after the set time, reducing the restraint force of the arc airbag 5 on the casing, allowing the casing to correct its posture under the action of gravity until the casing is in a vertical state.
