Description

Technical Field

[0001] The invention relates to geological exploration engineering equipment, in particular to a drilling tool trailer and an operating method thereof. Background Art

[0002] During geological exploration, the number of drill rods increases with increasing hole depth. Whether using traditional single-barrel drilling or rope coring, the drill string must be pulled out of the hole after each drilling pass or in the event of an accident or other unexpected situation. The string must then be unhooked and disassembled, moved out of the hole, and neatly arranged in front of the drill rig, awaiting subsequent use. Currently, the drill string is primarily operated by a lifter and stopper, with the operator lifting and moving the other end of the string back and forth across the drilling site. Currently, the length of the drill string ranges from 3.0 to 6.0 meters, and its weight ranges from 22 kg to 45.5 kg. Frequently lifting and moving the string is extremely physically demanding and difficult for operators, especially in rainy or snowy weather. On the other hand, as drilling depth increases, hundreds of drill tools need to be stacked. Each lifting and lowering operation requires hundreds of pulls and movements, placing a significant workload on the operators. As the most labor-intensive operation on a construction site, this often requires more than three people to assist, consuming resources and labor. Furthermore, operational efficiency is extremely low, impacting drilling progress, safety, and production costs. Due to irregularities in operation, the operator's lifting end often causes friction and collisions on site, which can easily damage threaded joints and cause debris to stick to them, affecting subsequent splicing.

[0003] Therefore, it is necessary to design equipment that can lift the drilling tools and move them back and forth, reduce the operating intensity, and improve the quality of engineering construction. Summary of the Invention

[0004] The purpose of the present invention is to provide a drilling tool trailer and an operating method thereof, so as to at least solve the problems of high work intensity and low operating efficiency when lifting the drilling tool to move back and forth.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is:

[0006] A drilling tool trailer, comprising a trailer body;

[0007] A drilling tool tray is provided on the top of the trailer body, and a drilling tool longitudinal groove is provided on the top of the drilling tool tray;

[0008] The bottom of the trailer body is provided with running wheels, and the trailer body is provided with a driving assembly of the running wheels.

[0009] Furthermore, the longitudinal groove of the drilling tool is a downwardly concave arc-shaped groove, and the cross section of the arc-shaped groove is arc-shaped.

[0010] Furthermore, the drilling tool tray includes an inner fixed trough body and an outer movable trough body, and the lower side of the movable trough body is a rod unloading surface, which extends from the outer end of the fixed trough body to the outer edge of the trailer body and tilts downward.

[0011] Furthermore, the fixed trough is fixed to the top of the trailer body, and the movable trough is located outside the fixed trough;

[0012] The movable trough body is a chain plate structure; the inner end of the movable trough body is connected to the outer end of the fixed trough body through a hinge; the outer end of the movable trough body is provided with a support rod, the top of the support rod is hinged to the outer end of the movable trough body, and the bottom end of the support rod is supported on the top outside the unloading rod surface.

[0013] Furthermore, the driving assembly includes a motor, a transmission shaft, a power transmission belt and a synchronous belt;

[0014] The motor is arranged on the top of the trailer body, the transmission shaft is located at the bottom of the trailer body, and the output shaft of the motor is connected to the transmission shaft through the power transmission belt;

[0015] The running wheels are provided in two groups, front and rear, each group includes two left and right running wheels, and the left and right running wheels are connected through axles; the transmission shaft is located between the front and rear axles, and the transmission shaft is respectively connected to the front and rear axles through two synchronous belts.

[0016] Furthermore, the running wheels are rail running wheels, which move on running rails arranged beside the drilling hole.

[0017] Furthermore, a pressure sensor for sensing the pressure of the drilling tool is provided at the bottom of the arc surface groove of the longitudinal groove of the drilling tool;

[0018] The trailer body is provided with a motor driver for controlling the electric motor;

[0019] A proximity switch is provided at the rear end of the longitudinal groove of the drilling tool.

[0020] Furthermore, a controller is provided on the trailer body, and the pressure sensor, the motor driver, and the proximity switch are all connected to the controller.

[0021] On the other hand, a method for operating the drill tool trailer is provided, wherein during the drilling phase:

[0022] The drill tool is dragged to the front end of the longitudinal groove of the drill tool by a winch through a wire rope, and the drill tool is changed from upright to inclined;

[0023] When the drill tool contacts the pressure sensor on the longitudinal groove of the drill tool, the pressure sensor senses the drill tool pressure and sends the sensing signal to the controller;

[0024] After receiving the sensing signal from the pressure sensor, the controller sends a control signal to the motor driver. The motor driver starts the motor according to the control signal, and the trailer body begins to move away from the drill hole and drags the drilling tool. After the drilling tool changes from tilt to horizontal, it touches the proximity switch at the rear end of the longitudinal slot of the drilling tool, and the proximity switch sends a trigger signal to the controller.

[0025] The controller receives the trigger signal from the proximity switch and sends a control signal to the motor driver. The motor driver stops the motor according to the control signal, the trailer body stops moving, and the drilling tool is placed in the drilling tool longitudinal groove.

[0028] When the drill tool leaves the proximity switch at the rear end of the longitudinal slot of the drill tool, the proximity switch is no longer triggered, and the controller sends a control signal to the motor driver. The motor driver starts the motor according to the control signal, and the trailer body starts to move towards the drill hole and drags the drill tool into the drill hole;

[0029] When the drill tool changes from tilt to upright and no longer contacts the pressure sensor on the longitudinal groove of the drill tool, the controller cannot receive the sensing signal of the pressure sensor and sends a control signal to the motor driver. The motor driver stops the motor according to the control signal, the trailer body stops moving, and the drill tool is placed in the borehole.

DETAILED DESCRIPTION

[0041] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present disclosure.

[0042] In the description of this patent, it should be understood that the terms "longitudinal", "transverse", "front", "rear", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing this patent and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limitations on this patent.

[0043] In the description of this patent, it should be noted that, unless otherwise expressly specified or limited, the terms "association," "access," "connection," and "setting" should be understood broadly. For example, they can refer to fixed connection or setting, detachable connection or setting, or integral connection or setting. They can also refer to physical connection, signal connection, or electrical connection, including other connections that can be adopted in accordance with the properties of the component itself. Those skilled in the art can understand the specific meanings of the above terms in this patent based on specific circumstances.

[0044] In a specific embodiment, the direction of the running rail is defined as the longitudinal direction, and the direction perpendicular to the running rail is defined as the transverse direction. The two transverse sides of the trailer body are defined as the outer side, and the direction close to the center of the trailer body is defined as the inner side. Figure 1 Define it as the front view, Figure 2 Defined as the back view, Figure 1 The two sides are defined as left and right.

[0045] Example 1:

[0046] This embodiment provides a drilling tool trailer that uses a mechanical trailer movement method instead of the current manual pulling movement method to move the drilling tool back and forth. Figure 1 and Figure 2 The drilling tool trailer includes a trailer body 1, which is a flat-plate-shaped body. A drilling tool tray 2 is provided on the right side of the top of the trailer body 1. A longitudinal drilling tool groove 12 is provided on the top of the drilling tool tray 2. The longitudinal drilling tool groove 12 is a downwardly concave arc-shaped groove with an arc-shaped cross-section, which can be semicircular or semi-elliptical. The shape matches the outer wall shape of the drilling tool 17, and the drilling tool 17 can be placed longitudinally in the arc-shaped groove. A flexible material such as a rubber layer can be provided on the groove surface of the arc-shaped groove to serve as a buffer and pad to protect the drilling tool 17 and provide friction for moving the drilling tool 17.

[0047] The trailer body 1 is provided with running wheels 11 on both sides of the bottom. The running wheels 11 are provided in two groups, front and rear, each group including two left and right running wheels 11. The left and right running wheels 11 are connected by a wheel axle. The trailer body 1 is provided with a driving assembly for the running wheels 11, such as Figure 5The drive assembly includes a motor 3, a drive shaft 4, a power transmission belt 5, and a timing belt 16. The motor 3 is mounted on the top left side of the trailer body 1, while the drive shaft 4 is located on the bottom left side of the trailer body 1. The output shaft of the motor 3 and the drive shaft 4 are both arranged horizontally and vertically connected by the power transmission belt 5. The drive shaft 4 is located between the front and rear axles and is connected to the front and rear axles via two timing belts 16. When the motor 3 is activated, it drives the running wheels 11 through the drive shaft 4 and the axles, thereby moving the trailer body 1.

[0048] In some embodiments, the running wheels 11 are rail running wheels, and two longitudinal running rails 6 are provided beside the drill hole. For example, the running wheels 11 are provided in the field directly in front of the drilling rig, and can move on the running rails 6. The running rails 6 can be steel rails, and the length of the running rails 6 can be appropriately extended. After the extension, the drilling tools can be moved over a longer distance. For example, when the drilling tools are stacked and spliced, the number of drilling tools that can be raised and lowered at one time can be doubled, thereby improving work efficiency.

[0049] The running rail 6 is buried parallel to the front of the drilling rig. During the burial process, it is anchored with anchor screws and other tools so that it cannot be moved in the acceptance state. During the burial process, the top surface of the running rail 6 must be 5-10 cm above the ground surface, and the top surface must be free of debris during use to ensure that the trailer body 1 does not derail during use.

[0050] like Figure 4 The drill tool pallet 2 includes an inner fixed trough body 13 and an outer movable trough body 14. The lower part of the movable trough body 14 is the rod unloading surface 7. The rod unloading surface 7 extends from the outer end of the fixed trough body 13 to the outer edge of the trailer body 1 and is inclined downward. The fixed trough body 13 is fixed to the top of the trailer body 1 and can be an integrated structure. The movable trough body 14 is located on the outer side of the fixed trough body 13. The movable trough body 14 is a chain plate structure, which is composed of multiple rectangular strips. The inner end of the movable trough body 14 is connected to the outer end of the fixed trough body 13 by a hinge; the outer end of the movable trough body 14 is provided with a support rod 19, the top of the support rod 19 is hinged to the outer end of the movable trough body 14, and the bottom end of the support rod 19 is supported on the top of the outer side of the rod unloading surface 7. When the drilling tool 17 needs to be unloaded from the drilling tool tray 2, the support columns 19 are tilted in a cross-direction, and the movable trough 14 is flattened from an arc shape along the unloading surface 7 to a flat plate. The drilling tool 17 rolls outward and downward along the unloading surface 7, thereby leaving the drilling tool longitudinal groove 12, and unloading is completed. Both the fixed trough 13 and the movable trough 14 are provided with a flexible material such as a rubber layer, which is disconnected at the connection point.

[0051] A pressure sensor 8 (AT8540, with a pressure range of 0-100 kg and an output current of 0-20 mA) is installed at the bottom of the curved groove of the drill tool's longitudinal groove 12 to sense drill tool pressure. A motor driver 9 (HB-860H) is installed on the trailer body 1 to control the motor 3 (a two-phase hybrid stepper motor 86BYGH250D). A proximity switch 15 (FR18-8DP) is installed at the rear end of the drill tool's longitudinal groove 12. A controller 10 (SM1 P) is also installed on the trailer body 1. The pressure sensor 8, motor driver 9, and proximity switch 15 are all connected to the controller 10. The pressure sensor 8 senses the drill tool pressure and converts it into an electrical signal, which is then transmitted to the controller 10. The controller 10 sends a pulse signal to the motor driver 9, which in turn drives the motor 3. The motor's operating parameters are configured in the upper debugging interface of the motor driver 9. These settings are linked to the signals transmitted by the controller 10 so that the received pulse signal can control the speed and direction of the motor 3, for example, setting the operating speed to 0-0.6 km / h. The controller 10 determines whether the drilling tool 17 is detached from the trailer through the proximity switch 15 .

[0052] This drilling tool trailer can support one end of the drilling tool 17 and reciprocate at the exploration site. Figure 3 The specific operation process is:

[0053] Example 2: During the drilling phase:

[0054] S1: Use a winch to drag the drilling tool 17 to the front end of the drilling tool longitudinal groove 12 through the wire rope 18, and the drilling tool 17 changes from upright to inclined;

[0055] S2: When the drill tool 17 contacts the pressure sensor 8 on the drill tool longitudinal groove 12, the pressure sensor 8 senses the drill tool pressure and sends a sensing signal to the controller 10;

[0056] S3: After receiving the sensing signal from the pressure sensor 8, the controller 10 sends a control signal to the motor driver 9. The motor driver 9 starts the motor 3 according to the control signal, and the trailer body 1 starts to move away from the drill hole and drags the drilling tool 17. The drilling tool 17 changes from tilt to horizontal and touches the proximity switch 15 at the rear end of the drilling tool longitudinal groove 12. The proximity switch 15 sends a trigger signal to the controller 10.

[0057] S4: The controller 10 receives the trigger signal from the proximity switch 15 and sends a control signal to the motor driver 9. The motor driver 9 stops the motor 3 according to the control signal, the trailer body 1 stops moving, and the drilling tool 17 is placed in the drilling tool longitudinal groove 12.

[0058] Example 3: In the drill-down phase:

[0059] S1: The drill tool 17 is lifted from the longitudinal groove 12 of the drill tool by a winch via a wire rope 18, and the drill tool 17 is turned from horizontal to inclined;

[0060] S2: The drilling tool 17 leaves the proximity switch 15 at the rear end of the drilling tool longitudinal slot 12. The proximity switch 15 is no longer triggered. The controller 10 sends a control signal to the motor driver 9. The motor driver 9 starts the motor 3 according to the control signal. The trailer body 1 starts to move, drives towards the drill hole, and drags the drilling tool 17 into the drill hole.

[0061] S3: When the drill tool 17 changes from tilted to upright and no longer contacts the pressure sensor 8 on the longitudinal groove 12 of the drill tool, the controller 10 does not receive the sensing signal of the pressure sensor 8 and sends a control signal to the motor driver 9. The motor driver 9 stops the operation of the motor 3 according to the control signal, the trailer body 1 stops moving, and the drill tool 17 is placed in the drill hole.

[0062] During the movement of the drill tool 17, no operator intervention is required, which greatly reduces the operator's labor intensity, reduces the number of operators involved in this operation process, and reduces the unsafe factors of operators moving back and forth on site, thereby improving production efficiency, reducing production costs, and enhancing safety at the drilling site. In addition, because the drill tool tray 2 is made of rubber material, it can greatly buffer pressure and prevent damage to the drill tool end. One side of the drill tool tray 2 can be opened and disassembled, allowing the drill tool to fall automatically to the drill tool storage area, further freeing up manpower and improving production.

[0063] The trailer structure of this invention is designed to suit actual on-site operations. It adopts a track-type operation mode. The longitudinal groove of the drill tool is semi-open, which facilitates the placement of the drill tool. The longitudinal groove of the drill tool is composed of two parts, and the movable groove body is connected by a hinge. The operation mode can be supported in a semi-arc shape. When the drill tool is unloaded, it can be flattened into a flat plate for easy unloading. During operation, the present invention integrates pressure sensors, controllers, proximity switches and motor drivers to achieve reciprocating motion of the trailer, thereby better matching on-site operations and improving production efficiency. In the field of geological exploration, this has revolutionized the original operating methods and methods, and for the first time conceived and created an intelligent trailer for lifting drill tools.

[0064] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art can make several simple deductions, modifications or substitutions based on the concept of the present invention.
