Description

Technical Field

[0001] This application relates to the technical field of drilling equipment, and particularly to a rod connecting device and a drilling equipment. Background Art

[0002] With the development of urban infrastructure construction, the depth of foundation pile construction continues to break through downward. For a single drilling, longer drill pipes are required. However, on the market, the standard lengths of drill pipes are mainly 3 meters, 6 meters, 9 meters, and 12 meters. This leads to the need for multiple rod connections to achieve the required drill depth.

[0003] Currently, the main rod connection methods on the market are as follows:

[0004] First, external equipment-assisted rod connection: By borrowing auxiliary equipment (crane, excavator), the drill pipe to be connected is lifted below the power head, and then the drill pipe is manually assisted to be vertical and aligned with the hole. The power head descends for rod connection, and manual pin insertion is carried out. The disadvantage of this rod connection method is that relevant equipment assistance is required, and the auxiliary personnel need to be lifted below the power head to command the operation and manually insert the pins, which has a certain risk. In addition, the efficiency is very low.

[0005] Second, double power head rod connection: Equipped with two power heads, in the form of a relay baton, through the translation of the whole machine equipment, manual assistance, hole alignment, the power head descends for rod connection, and manual pin insertion is carried out. The disadvantage of this rod connection method is that two power heads need to be equipped, the cost is high, the safety and stability of the whole machine are poor, and auxiliary personnel still need to stand below the power head to command the operation and manually insert the pins, which has a certain risk.

[0006] Third, robotic arm rod connection: By borrowing a robotic arm, the drill pipe to be connected is swung below the power head, and then the drill pipe is manually assisted to be vertical and aligned with the hole. The power head descends for rod connection, and manual pin insertion is carried out. The disadvantage of this rod connection method is that relevant equipment assistance is required, and the auxiliary personnel need to be lifted below the power head to command the operation and manually insert the pins, and there is a risk that the drill pipe breaks away from the robotic arm, with high danger and low efficiency.

[0028] Compared with the above background art, the rod connecting device provided by the embodiments of this application includes a column, a power head, a pin mechanism, at least two swing arm mechanisms, and at least two holders.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0052] In order to enable those skilled in the art of this technology to better understand the solution of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0053] It should be noted that the orientation words such as "upper end, lower end, left side, right side" described below are defined based on the accompanying drawings of the specification.

[0054] Please refer to Figures 1 to 8 , Figure 1 which is a schematic structural diagram of the rod connecting device in the embodiment of the present application; Figure 2 is Figure 1 a schematic structural diagram of the pin mechanism in the rod connecting device shown; Figure 3 is Figure 1 a front view of the swing arm mechanism in the rod connecting device shown; Figure 4 is Figure 1 a top view of the swing arm mechanism in the rod connecting device shown; Figure 5 is Figure 1 a schematic structural diagram of the first retainer in the rod connecting device shown; Figure 6 is Figure 5 a working schematic diagram of the first retainer shown; Figure 7 is Figure 1 a schematic structural diagram of the second retainer in the rod connecting device shown; Figure 8 is a schematic flow diagram of the rod connecting operation of the rod connecting device in the embodiment of the present application.

[0055] The rod connecting device provided by the embodiment of the present application includes a column 8, a power head 1, a pin mechanism 2, at least two swing arm mechanisms, and at least two retainers.

[0056] The power head 1 is arranged on the column 8, and the power head 1 is used to move along the first direction. Among them, a guide rail / slide rail is provided on the column 8, and the power head 1 is arranged on the guide rail / slide rail and can move up and down along it.

[0057] The pin mechanism 2 is connected to the power head 1. The pin mechanism 2 includes a pin driving assembly 2.6 and a drill pipe pin 2.5. The pin driving assembly 2.6 is connected to the drill pipe pin 2.5, and the pin driving assembly 2.6 is used to drive the drill pipe pin 2.5 to move along a second direction perpendicular to the first direction to fix or release the drill pipe 4.

[0058] It should be noted that the first direction can be the vertical direction as shown in Figure 1 , or the extending direction of the column 8, and the second direction can be the telescopic direction of the pin driving assembly 2.6 in the horizontal plane as shown in Figure 2 , or the axis direction of the drill pipe pin 2.5.

[0059] The above-mentioned pin driving assembly 2.6 can be an electric cylinder. Through the telescopic movement of the electric cylinder, the drill pipe pin 2.5 is driven to extend and retract. When the electric cylinder extends, the drill pipe pin 2.5 releases the drill pipe 4 located inside the pin mechanism 2. When the electric cylinder retracts, the drill pipe pin 2.5 extends into the pin mechanism 2 and abuts against the drill pipe 4, so as to achieve the purpose of fixing the drill pipe 4.

[0060] At least two swing arm mechanisms are arranged at intervals in the height direction of the column 8. Any swing arm mechanism includes a swing arm driving assembly 3.2 and a swing arm body 3.1. The swing arm driving assembly 3.2 is arranged on the column 8 and connected to the swing arm body 3.1. The swing arm body 3.1 is rotatably connected to the column 8. The swing arm body 3.1 is used to place the drill pipe 4, and the swing arm driving assembly 3.2 is used to drive the swing arm body 3.1 to rotate.

[0061] Of course, according to actual needs, the swing arm driving assembly 3.2 can be an oil cylinder, and the oil cylinder is used to drive the swing arm body 3.1 to rotate, so as to bring the drill pipe 4 to the position directly below the power head 1 during rod connection.

[0062] At least two holders are movably connected to the column 8 and connected to the power head 1. Any holder includes a jaw driving assembly and a jaw body. The jaw driving assembly is connected to the jaw body, and the jaw driving assembly is used to drive the jaw body to open and close to ensure the perpendicularity of the drill pipe 4.

[0063] The following specifically describes the rod connection steps of the rod connection device provided by the embodiment of the present application:

[0064] The first step: Place a first drill pipe 4.1 on at least two swing arm bodies 3.1, and the power head 1 itself has a second drill pipe 4.2;

[0065] The second step: The power head 1 moves downward along the first direction and drives the second drill pipe 4.2 to drill to the specified position;

[0066] The third step: One of at least two holders clamps the second drill pipe 4.2. The pin driving assembly 2.6 of the pin mechanism 2 is used to drive the drill pipe pin 2.5 to move along the second direction to release the second drill pipe 4.2. The power head 1 moves upward along the first direction and separates from the second drill pipe 4.2;

[0067] Step 4: Another one of the at least two retainers is opened, and the swing drive assemblies 3.2 of the at least two swing arm mechanisms drive the corresponding swing arm bodies 3.1 to rotate, so that the first drill pipe 4.1 rotates to directly below the power head 1;

[0068] Step 5: The power head 1 moves downward in the first direction. After the first drill pipe 4.1 extends into the power head 1, the drill pipe pin 2.5 is driven by the pin drive assembly 2.6 to move in the second direction to connect the first drill pipe 4.1 and the power head 1, and another one of the at least two retainers is closed;

[0069] Step 6: The power head 1 moves upward in the first direction, so that the first drill pipe 4.1 disengages from the swing arm bodies 3.1 of the at least two swing arm mechanisms. The swing drive assemblies 3.2 of the at least two swing arm mechanisms drive the corresponding swing arm bodies 3.1 to rotate back to the original position, align the first drill pipe 4.1 and the second drill pipe 4.2, and the power head 1 moves downward in the first direction until the first drill pipe 4.1 is docked with the second drill pipe 4.2, completing the rod connection.

[0070] The rod connection device arranged in this way has the following beneficial effects:

[0071] First, the drill pipe pin 2.5 is driven by the pin drive assembly 2.6 of the pin mechanism 2 to move in the second direction to fix or release the drill pipe 4. This setting method realizes the unmanned operation during the connection of the drill pipe 4, reduces the safety risk, and improves the rod connection efficiency.

[0072] Second, the swing drive assemblies 3.2 of the at least two swing arm mechanisms drive the corresponding swing arm bodies 3.1 to rotate, realizing the unmanned operation during the connection of the drill pipe 4, reducing the safety risk, and improving the rod connection efficiency. At the same time, the drill pipe 4 is placed and positioned by the at least two swing arm bodies 3.1, greatly reducing the risk of the drill pipe 4 falling during the construction of the equipment.

[0073] Third, the gripper drive assembly of the at least two retainers drives the gripper body to open and close, which not only increases the verticality during the rod connection of the drill pipe 4, improves the rod connection efficiency, but also plays a role in preventing the drill pipe 4 from falling into the hole during the rod connection.

[0074] In some embodiments, the pin mechanism 2 further includes a drill pipe joint 2.1, a guiding slide bar 2.3, and a connecting plate 2.4.

[0075] Among them, the drill pipe joint 2.1 is connected to the power head 1 through a flange. The drill pipe joint 2.1 is used to accommodate the drill pipe 4. The drill pipe pin shaft 2.5 is movably embedded in the drill pipe joint 2.1 along the second direction. When the drill pipe pin shaft 2.5 extends into the interior of the drill pipe joint 2.1 and abuts against the drill pipe 4, it can play a role in fixing the drill pipe 4; the guiding slide bar 2.3 is arranged on the drill pipe joint 2.1. The guiding slide bar 2.3 extends along the second direction, and the axis of the guiding slide bar 2.3 is parallel to the axis of the drill pipe pin shaft 2.5; the connecting plate 2.4 connects the drill pipe pin shaft 2.5 and the pin driving assembly 2.6, and the connecting plate 2.4 is sleeved on the guiding slide bar 2.3, so that the connecting plate 2.4 can slide along the guiding slide bar 2.3.

[0076] It can be understood that the setting of the guiding slide bar 2.3 is used to play a guiding role during the insertion and extraction movements of the drill pipe pin shaft 2.5, so as to ensure the stability of the drill pipe pin shaft 2.5 during the insertion and extraction movements.

[0077] Moreover, in order to facilitate the automatic control of the pin mechanism 2, the pin mechanism 2 further includes a control module. The control module is communicatively connected to the pin driving assembly 2.6, and the control module is used to control the start and stop of the pin driving assembly 2.6.

[0078] In some embodiments, the control module is a remote control module 2.2. The number of the pin driving assemblies 2.6, the drill pipe pin shafts 2.5 and the guiding slide bars 2.3 is two. The remote control module 2.2 is communicatively connected to the two pin driving assemblies 2.6. The pin mechanism 2 further includes a mounting plate 2.7. The mounting plate 2.7 is arranged at the bottom of the drill pipe joint 2.1, and the remote control module 2.2 and the two pin driving assemblies 2.6 are both mounted on the mounting plate 2.7.

[0079] In this way, the remote control module 2.2 can be used to remotely drive the electric cylinder to work. Through the telescopic movement of the electric cylinder, the drill pipe pin shaft 2.5 is driven to extend into the interior of the drill pipe joint 2.1 or be pulled out from the drill pipe joint 2.1. When the electric cylinder extends, the drill pipe pin shaft 2.5 releases the drill pipe 4 located inside the pin mechanism 2. When the electric cylinder retracts, the drill pipe pin shaft 2.5 extends into the interior of the pin mechanism 2 and abuts against the drill pipe 4, so as to achieve the purpose of fixing the drill pipe 4.

[0080] In addition, the electric cylinder has a stroke signal feedback function during the telescopic movement. For example, when the electric cylinder extends in place, it feeds back the signal of extending in place to the ground remote control device. At this time, the system determines that the drill pipe pin shaft 2.5 is pulled out in place, indicating that the drill pipe 4 has been released and the next step can be carried out. When the electric cylinder retracts in place, it feeds back the signal of retracting in place to the ground remote control device. At this time, the system determines that the drill pipe pin shaft 2.5 extends in place, indicating that the drill pipe 4 has been completely fixed and the next step can be carried out.

[0081] In some embodiments, in order to facilitate the positioning of the drill pipe 4, at least two swing arm mechanisms are each provided with a structure for preventing the drill pipe 4 from detaching.

[0082] Specifically, a concave platform 3.11 is provided on any one of the swing arm bodies 3.1. The concave platform 3.11 is used to cooperate with the limiting ring 4.11 on the drill pipe 4 to achieve the positioning of the drill pipe 4 in the first direction. The concave platform 3.11 has an opening 3.12 for the drill pipe 4 to detach from the concave platform 3.11 when the limiting ring 4.11 exceeds the swing arm body 3.1.

[0083] It can be seen that when placing the drill pipe 4, the limiting ring 4.11 (ring) on the drill pipe 4 is placed in the corresponding concave platform 3.11. At this time, by the contact and cooperation between the concave platform 3.11 and the limiting ring 4.11, it can be ensured that the drill pipe 4 will not detach downward from the swing arm mechanism. In this way, the corresponding swing arm body 3.1 can be driven to swing by the oil cylinder, so as to turn the drill pipe 4 to the designated position; in addition, after the drill pipe 4 is connected to the power head 1, the power head 1 needs to be lifted to drive the drill pipe 4, so that the limiting ring 4.11 moves upward to a height exceeding the upper part of the swing arm body 3.1, and then the oil cylinder drives the swing arm body 3.1 to reset, and the swing arm mechanism detaches from the drill pipe 4.

[0084] In order to facilitate the swing arm driving assembly 3.2 to drive the swing arm body 3.1 to rotate, any one of the swing arm mechanisms further includes a hinge support and a connecting seat. The fixed end of the swing arm driving assembly 3.2 is hinged to the hinge support, the movable end of the swing arm driving assembly 3.2 is hinged to the connecting seat, the connecting seat is connected to the end of the swing arm body 3.1 far from the concave platform 3.11, and the end of the swing arm body 3.1 far from the concave platform 3.11 is rotatably connected to the column 8 through a rotating shaft.

[0085] The above-mentioned swing arm driving assembly 3.2 can be an oil cylinder. Through the telescopic movement of the oil cylinder, the swing arm body 3.1 can be driven to rotate relative to the column 8 around the axis of its rotating shaft, so as to turn the drill pipe 4 to the designated position.

[0086] In this embodiment, the number of swing arm mechanisms is preferably two, namely the upper swing arm mechanism 3 and the lower swing arm mechanism 6. The upper swing arm mechanism 3 and the lower swing arm mechanism 6 are spaced apart on the column 8, and the upper swing arm mechanism 3 and the lower swing arm mechanism 6 move synchronously during the rod connection process to ensure the stability of the movement of the drill pipe 4.

[0087] In some embodiments, any one of at least two retainers further includes a cage. A guide rail / slide rail is provided on the column 8, and the cage is slidably connected to the guide rail / slide rail.

[0088] Among them, the gripper body is rotatably connected to the cage, and the fixed end of the gripper driving assembly is hinged to the cage, and the movable end of the gripper driving assembly is hinged to the corresponding gripper body. Of course, the gripper driving assembly can also be an oil cylinder assembly. In this way, through the telescopic movement of the gripper driving assembly, the corresponding gripper body can be driven to rotate relative to the cage to realize the opening and closing of the gripper body and ensure the drilling perpendicularity.

[0089] In this embodiment, the number of retainers can be set to two. Specifically, the lower retainer is the first retainer 7, and the upper retainer is the second retainer 5. The first retainer 7 includes two first gripper bodies 7.1, two first gripper driving assemblies 7.2 and a first cage 7.3. The two first gripper bodies 7.1 are rotatably connected to the first cage 7.3, and the fixed end of the first gripper driving assembly 7.2 is hinged to the first cage 7.3, and the movable end of the first gripper driving assembly 7.2 is hinged to the corresponding first gripper body 7.1. Through the telescopic movement of the first gripper driving assembly 7.2, the corresponding first gripper body 7.1 can be driven to rotate relative to the first cage 7.3 to realize the opening and closing of the two first gripper bodies 7.1; the second retainer 5 includes two second gripper bodies 5.1, two second gripper driving assemblies 5.2 and a second cage 5.3. The two second gripper bodies 5.1 are rotatably connected to the second cage 5.3, and the fixed end of the second gripper driving assembly 5.2 is hinged to the second cage 5.3, and the movable end of the second gripper driving assembly 5.2 is hinged to the corresponding second gripper body 5.1. Through the telescopic movement of the second gripper driving assembly 5.2, the corresponding second gripper body 5.1 can be driven to rotate relative to the second cage 5.3 to realize the opening and closing of the two second gripper bodies 5.1.

[0090] The second retainer 5 is connected to the power head 1 through a second chain 5.4, and the second retainer 5 can move up and down following the power head 1. The first retainer 7 is connected to the second retainer 5 through a first chain 7.5, and the first retainer 7 can move up and down following the second retainer 5.

[0091] In some embodiments, either the first cage 7.3 of the first retainer 7 or the column 8 is provided with a limit shaft 7.4, and the other is provided with a limit hook 8.1. The limit hook 8.1 cooperates with the limit shaft 7.4 to limit the sliding of the first retainer 7.

[0092] That is to say, when the lower first retainer 7 moves to the bottom of the column 8, the cooperation of the limit shaft 7.4 and the limit hook 8.1 will limit its further downward movement. When the first retainer 7 moves to the bottom of the column 8, the first gripper body 7.1 can be closed to clamp the drill pipe 4 to prevent the drill pipe 4 from falling down.

[0093] To sum up, asFigure 8 As shown, the connecting rod step of the connecting rod device provided in the embodiment of the present application mainly includes:

[0094] Step 1: Place a first drill rod 4.1 on the two swing arm bodies 3.1, and the power head 1 is equipped with a second drill rod 4.2;

[0095] Step 2: The power head 1 moves downward along the first direction and drives the second drill rod 4.2 to drill to the designated position;

[0096] Step 3: The first retainer 7 clamps the second drill rod 4.2, and the bolt driving assembly 2.6 of the bolt mechanism 2 drives the drill rod pin 2.5 to move along the second direction to release the second drill rod 4.2. The power head 1 moves upward along the first direction and separates from the second drill rod 4.2, and the power head 1 is lifted to the specified position;

[0097] Step 4: The second retainer 5 is opened, and the swing arm driving components 3.2 of the two swing arm mechanisms drive the corresponding swing arm bodies 3.1 to rotate, so that the first drill rod 4.1 rotates to the bottom of the power head 1;

[0098] Step 5: The power head 1 moves downward in the first direction, aligns the hole, and the latch mechanism 2 is started. After the first drill rod 4.1 is inserted into the power head 1, the drill rod pin 2.5 is driven by the latch drive assembly 2.6 to insert into the drill rod joint 2.1 to connect the first drill rod 4.1 and the power head 1, and the second retainer 5 is closed;

[0099] Step 6: The power head 1 continues to move upward along the first direction, so that the first drill rod 4.1 is separated from the swing arm body 3.1 of the two swing arm mechanisms, and the swing arm drive components 3.2 of the two swing arm mechanisms drive the corresponding swing arm body 3.1 to rotate and reset, aligning the first drill rod 4.1 and the second drill rod 4.2, and the power head 1 moves downward along the first direction until the first drill rod 4.1 is docked with the second drill rod 4.2 to complete the rod connection.

[0100] With such an arrangement, the arrangement of the latch mechanism 2 realizes unmanned operation of the latch when connecting the drill rod 4, reduces safety risks, and improves the efficiency of connecting rods; the arrangement of the two swing arm mechanisms realizes unmanned operation of the swinging of the drill rod 4 when connecting the drill rod 4, reduces safety risks, and improves the efficiency of connecting rods. At the same time, the structure on the two swing arm bodies 3.1 to prevent the drill rod 4 from detaching greatly reduces the risk of the drill rod 4 falling during the equipment construction process; the opening and closing action design of the two retainers not only increases the verticality of the drill rod 4 during the connecting process and improves the efficiency of the connecting rod, but also prevents the drill rod 4 from falling into the hole when connecting the rod.
