DETAILED DESCRIPTION

[0048] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the following will be combined with the appended Figure 1 -Attached Figure 4 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0049] The present application embodiment discloses a drilling inclination auxiliary system for a drilling tower. Figure 1 The auxiliary system may include a fixed pulley 100 , a rope reel 200 , a cable 300 , an inclinometer 400 , a distance measuring assembly 500 and a brake assembly 600 .

[0050] Among them, the fixed pulley 100, the rope reel 200 and the cable 300 are all structures on the derrick body and are suspended in the middle of the derrick. The fixed pulley 100 is rotatably connected to the derrick body, and the rope reel 200 is installed on the derrick body for winding or unwinding the cable 300; one end of the cable 300 is wound around the rope reel 200, and the other end is passed around the fixed pulley 100, and the inclinometer 400 is hung. The distance measuring component 500 is used to automatically measure the number of meters of descent of the inclinometer 400; the brake component 600 is used to brake the rope reel 200. During the braking period, the staff operates the inclinometer 400 to perform inclinometer operation; when not braking, the inclinometer 400 descends at a constant speed.

[0051] Reference Figure 2 The ranging component 500 may include a rotating wheel, an encoder 510 , a signal transmitter 520 and a signal receiver 530 .

[0052] The rotating wheel is coaxially fixedly connected to the rotating shaft of the fixed pulley 100, and the encoder 510 is coaxially installed on the rotating wheel to convert the number of rotations of the rotating wheel into an electrical signal; the rotating wheel can be a gear. The encoder 510 can be powered by a lithium battery, and the lithium battery can be used for more than 30 days each time it is fully charged, thereby meeting the use requirements of a construction cycle. The signal transmitter 520 is installed at the fixed pulley 100 and is electrically connected to the encoder 510 for sending electrical signals. The signal receiver 530 is installed at the rope reel 200 for receiving electrical signals and is wirelessly connected to the signal transmitter 520. The encoder 510 converts the number of revolutions of the rotating wheel into an electrical signal and transmits it to the signal receiver 530. After the signal receiver 530 receives the electrical signal, it converts the number of revolutions into the number of meters of descent.

[0053] In addition, the auxiliary system may further include a controller 700 , which is communicatively connected to the signal receiver 530 ; the inclinometer 400 may also be communicatively connected to the controller 700 .

[0054] In another embodiment of the auxiliary system, the auxiliary system may further include a display screen 800 , which is equipped with a lithium battery, and in the event of a power outage, the lithium battery supplies power. The display screen 800 may be communicatively connected with the signal receiver 530 and the controller 700 .

[0055] Reference Figure 3 The display screen 800 includes a meter display module 810, a reset button 820, a brake button 830 and a brake release button 840. The meter display module 810 is used to display the current meter and the next brake meter. After the display screen 800 is turned on, the current meter shows 0 meters; the next brake meter is displayed as "-", indicating that the brake function is not activated. When the brake button 830 and the brake release button 840 are pressed at the same time, the next brake meter is displayed as 25 meters, that is, the next brake position. After the reset button 820 is pressed for a set time, the meter display module 810 shows that the current meter is 0 meters; after pressing the reset button 820, pressing the brake button 830 will increase the next brake meter; after pressing the reset button 820, pressing the brake release button 840 will reduce the next brake meter.

[0056] It should be noted that the number of meters for the next brake is the smallest of the specific values ​​greater than the current number of meters by default, and the specific data is pre-set in the controller 700. For example, when the current number of meters is 24 meters, the brake will be applied at the 25-meter position; the specific value can be 0 meters, 25 meters, 50 meters, 100 meters, 150 meters, 200 meters, 250 meters, 300 meters, 350 meters, 400 meters, 450 meters, 500 meters, 550 meters, 600 meters, 650 meters, 700 meters, 750 meters, 800 meters. When the number of meters for the next brake is greater than 800 meters, the brake will no longer be limited and manual brake is required, and the rope reel 200 retains the original manual brake.

[0057] In addition, the display screen 800 also has a built-in voice announcer, and when the current number of meters reaches the brake position, the voice announcer broadcasts a prompt voice.

[0058] Reference Figure 4 The brake assembly 600 may include a brake slave wheel 610 , a brake plate 620 , a brake master wheel 630 and a driving component 640 .

[0059] The brake slave wheel 610 is coaxially fixedly connected to the rope reel 200; the brake plate 620 is slidably connected to the derrick body; the brake main wheel 630 is rotatably connected to the brake plate 620, and the brake main wheel 630 is transmission-connected to the brake slave wheel 610 through a brake belt. The driving component 640 is used to drive the brake plate 620 to slide, so that the brake main wheel 630 tightens or loosens the brake belt.

[0060] The driving component 640 may include a brake motor 641 and a brake screw 642. The brake motor 641 is mounted on the derrick body, the brake screw 642 is coaxially fixedly connected to the output shaft of the brake motor 641, and the brake plate 620 is threadedly connected to the brake screw 642. In other embodiments, the driving component 640 may also be an electric push rod.

[0061] The implementation principle of this embodiment is:

[0062] When measuring inclination, the rope reel 200 unwinds the cable 300, and the cable 300 drives the inclinometer 400 to descend at a constant speed. The encoder 510 collects the number of rotations of the rotating wheel and converts the number of rotations into an electrical signal, which is transmitted to the signal receiver 530 through the signal transmitter 520. The signal receiver 530 converts the number of rotations into the number of meters of descent and sends it to the display screen 800 and the controller 700. The display screen 800 displays the current number of meters and the next braking number of meters. When the current number of meters reaches the next braking number of meters, the inclinometer 400 reaches the braking position, and the display screen 800 broadcasts a prompt voice. The controller 700 sends a braking command to the brake motor 641, and the brake motor 641 drives the brake screw 642 to rotate, and the brake screw 642 drives the brake plate 620 to move, so that the brake pulley 610 tightens the brake belt to achieve the braking of the rope reel 200. During the braking process, the inclinometer 400 performs inclination measurement.

[0063] The above are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application in sequence. Any feature disclosed in this specification (including the abstract and drawings), unless otherwise stated, can be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.
