[0002] Drilling rigs are crucial equipment for the exploration and development of resources such as oil and geothermal energy, and their performance and efficiency directly impact drilling results. With industrial development and technological advancements, the demands for the intelligence and efficiency of drilling rigs are increasing. To meet this need, automated drill string handling systems have been widely applied in the upgrading and retrofitting of oil drilling rigs. This automated drill string handling system utilizes advanced automation technology and equipment to automate the processing and management of drill strings within the rig. The system comprises components such as a drilling platform manipulator, a hydraulic tongs intelligent control system, a hoist intelligent control device, a power catwalk, and an integrated drilling control system.

[0003] The main function of a powered catwalk is to transport a single drill bit from the storage yard to the drilling platform. Powered catwalk devices typically use a combination of ramps and support arms. Through the movement of the rocker arm, the conveyor frame along with the drill bit is sent to a higher height.

[0004] Traditional power catwalks are mainly used for oil drilling rigs. Oil exploration and development are mostly located in remote fields with ample site conditions. However, geothermal exploration and development are mostly located in cities with smaller construction sites and more restrictive conditions. When using a power catwalk, the drilling tools need to be neatly laid flat on both sides of the catwalk, which requires a large area of ​​the site and thus affects the drilling operation.

[0033] Embodiment 1

[0034] Reference Figure 1 , 3 ~5 and 7, the first embodiment of the present application provides a geothermal drilling rig drill rod warehouse, this tube warehouse includes storage structure 100, the storage structure 100 is used for storing the drill Z used in the drilling rig construction; specifically, it includes a plurality of groups of layered placement layers 101, and each group of placement layers 101 has a spacing J. Among them, the storage structure 100 is placed by the layered placement layer 101, and the spacing J between each placement layer 101 should not be less than the diameter of the drill Z, so as to avoid the influence of the upper placement layer 101 on the drill Z on the lower placement layer 101.

[0035] Further, the upper and lower adjacent groups of placement layers 101 are parallel and horizontally distributed, and the two ends are aligned. That is, all the placement layers 101 are arrayed from top to bottom, and each placement layer 101 is independent of each other, and the drill Z is taken from each placement layer 101 without affecting each other.

[0036] For each group of placement layers 101, it includes a plurality of parallel distribution of inner lining rods 101a, a transmission wheel 101b is arranged on each inner lining rod 101a at equal intervals, and a conveying belt 101c is arranged on the outer surface of each group of transmission wheels 101b for synchronous transmission.

[0037] Among them, the inner lining rod 101a is used for the fixation of the placement layer 101, and is fixed in a certain storage space to form the storage structure 100; the transmission wheel 101b is installed on the inner lining rod 101a, which is used for installing the conveying belt 101c; so that the conveying belt 101c can convey the drill Z as a whole. Here, it should be noted that the conveying belt 101c is also connected with an external electric control driving wheel, so as to control the start and stop of the conveying belt 101c through the control system.

[0038] On one side of all the placing layers 101, i.e. on the conveying direction of the conveying belt 101c, a lifting assembly 200 is installed, which is used to put or take out the drilling tools Z from each group of placing layers 101.

[0039] Specifically, the lifting assembly 200 comprises a lifting member 201, a gripper 202 and an adjusting support plate 203 arranged on the top of the lifting member 201; the lifting member 201 can be lifted and lowered to change the height; in the prior art, a hydraulic cylinder is preferred; the drilling tools Z are lifted by the gripper 202 and the adjusting support plate 203 arranged on the top, and the angle of the adjusting support plate 203 is changed by the control system, so that the limiting or releasing of the drilling tools Z placed on the gripper 202 can be realized.

[0040] Further, the storage structure 100 and the lifting assembly 200 can be installed on the platform frame on both sides of the power catwalk, or can be installed in an independent frame structure; in the present scheme, it is preferred to be installed in the pipe warehouse frame 300 of an independent structure.

[0041] The pipe warehouse frame 300 is an independent frame structure, which is hollow inside and forms a receiving cavity M; the inner lining rods 101a of each group of placing layers 101 are fixed on the inner side wall of the pipe warehouse frame 300, and the hydraulic cylinder serving as the lifting member 201 is also fixed at the bottom on the inner side wall of the pipe warehouse frame 300, and forms an entrance for the drilling tools Z on the top surface of the pipe warehouse frame 300, which is convenient for the taking and placing of the drilling tools Z.

[0042] Further, in the use process, the drilling tools Z can be put into and taken out of the storage structure 100 in the pipe warehouse frame 300; the process is described as follows:

[0043] Fill the drill pipe: the drill pipe warehouse can be filled with drill tools in advance before being transported to the construction site. When working, the lifting member 201 is lifted from the accommodation cavity M to a certain height above the pipe warehouse frame 300. The drill tool Z is transported to the lifting member 201 by an external crane or manipulator, and then the drill tool Z is gently placed on the gripper 202. After the lifting member 201 receives the drill tool Z, it is first lowered to the horizontal height of the lowermost row of the conveying belt 101c or a position slightly higher than the horizontal height. The adjusting support plate 203 near the conveying belt 101c is controlled to expand, so that the drill tool Z can be rolled along the adjusting support plate 203 to the conveying belt 101c. Then, the adjusting support plate 203 is retracted, the lifting member 201 is lifted, and the second drill tool below the crane or manipulator is received. The lifting member 201 continues to be lowered to the horizontal height of the lowermost row of the conveying belt 101c or a position slightly higher than the horizontal height. The conveying belt 101c is controlled to rotate a certain distance away from the lifting member 201, so that the first drill tool Z moves and leaves a space for a drill tool Z. The lifting member 201 places the second drill tool Z on the conveying belt 101c. The conveying belt 101c and the lifting member 201 repeatedly perform the above operation. When the lowermost row of the conveying belt 101c is filled with drill tools Z, the lifting member 201 starts to place the drill tools Z on the second-to-last row of the conveying belt 101c. When all the conveying belts 101c are filled with drill tools Z, the process of filling the drill tools Z is completed. As shown in FIG. Figure 3 The drill pipe warehouse helps the overall transportation after filling the drill tools.

[0044] Drill tool on the drilling platform: the drill pipe warehouse is transported to the construction site and placed at the target position directly below the manipulator on the drilling platform. When working, the lifting member 201 is lifted to a position slightly lower than the uppermost layer of the conveying belt 101c. The conveying belt 101c rotates towards the lifting member 201, so that the outermost drill tool Z rolls onto the gripper 202 above the top of the lifting member 201. The conveying belt 101c stops rotating, and the lifting member 201 supports the drill pipe warehouse and lifts it to a certain height. After the manipulator on the drilling platform grabs the drill tool, the lifting member 201 is lowered to the position of the uppermost layer of the conveying belt 101c to receive the second drill tool Z, and the above operation is repeated. When all the drill tools Z on the uppermost layer of the conveying belt 101c are lifted by the lifting member 201 and transported to the drilling platform, the drill tools Z on the second row of the conveying belt 101c from top to bottom are transported, and finally the drill tools Z on the bottom layer of the conveying belt 101c are transported.

[0045] When all the drill tools Z in any drill pipe warehouse are completely removed, the next drill pipe warehouse can be replaced for continuous construction.

[0046] Example 2

[0047] Referring to Figure 2And Figure 8, for the second embodiment of the utility model, this embodiment is different from the first embodiment is that the placement layer 101 still has other implementation structure, specific: the upper and lower adjacent group placement layer 101 parallel and horizontal distribution, adjacent group placement layer 101 in the distribution direction both ends are staggered, staggered spacing is not less than the size of interval J; the end of the placement layer 101 of interval group is aligned.

[0048] In detail, each group of placement layer 101 is parallel and horizontally distributed, but in order to connect the placement layer 101 of each layer, the placement layer 101 is distributed staggered with each other; So that the drill Z can roll from the placement layer 101 of the upper layer to the placement layer 101 of the lower layer. This arrangement can simplify the control process of the storage structure 100 and the lifting assembly 200. And the storage structure 100 has only one placement port (i.e. the end of the placement layer 101 of the top layer), and only one take-out port (i.e. the end of the placement layer 101 of the bottom layer).

[0049] Similarly, for each group of placement layer 101, it includes several parallel distribution of inner lining rod 101a, each inner lining rod 101a is provided with transmission wheel 101b at equal intervals, and the transmission belt 101c is provided on the outer surface of each group of transmission wheel 101b for synchronous transmission.

[0050] Among them, the inner lining rod 101a is used for the fixation of the placement layer 101, which is fixed in a certain storage space to form the storage structure 100; The transmission wheel 101b is installed on the inner lining rod 101a for installing the transmission belt 101c; So that the transmission belt 101c can transmit the drill Z as a whole. Here, it should be noted that the transmission belt 101c is also connected with the external electric control driving wheel to control the start and stop of the transmission belt 101c through the control system. And in this embodiment, the rotation direction of the transmission belt 101c controlled by the adjacent layer driving wheel is opposite.

[0051] On one side of all the placement layer 101, that is, in the transmission direction of the transmission belt 101c, the lifting assembly 200 is installed, which is used for putting or taking out the drill Z from each group of placement layer 101.

[0052] Specifically, the lifting assembly 200 includes lifting piece 201, gripper 202 and adjusting support plate 203 arranged on the top of the lifting piece 201; The lifting piece 201 can move up and down to change the height; In the prior art, the hydraulic cylinder is preferred; The drill Z is lifted by the gripper 202 and the adjusting support plate 203 installed on the top, and the angle of the adjusting support plate 203 is changed through the control system, so that the drill Z placed in the gripper 202 can be limited or released. In this implementation structure, the lifting piece 201 has only two places for taking and placing the drill Z, which greatly reduces the control difficulty.

[0053] The storage structure 100 and the lifting assembly 200 can be mounted on the platform frame on both sides of the power catwalk, or can be mounted in an independent frame structure, which is preferably an independent pipe bin frame 300 in this embodiment.

[0054] The pipe bin frame 300 is an independent frame structure, which is hollow inside and forms a receiving cavity M. The inner lining rods 101a of each group of placement layers 101 are fixed to the inner side wall of the pipe bin frame 300, and the hydraulic oil cylinder serving as the lifting member 201 is also fixed to the inner side wall of the pipe bin frame 300, and the top surface of the pipe bin frame 300 forms an entrance and exit for the drilling tools Z, facilitating the taking and placing of the drilling tools Z.

[0055] Further, in the use process, the drilling tools Z can be placed into the storage structure 100 in the pipe bin frame 300, and the drilling tools Z can be taken out; the process is described as follows:

[0056] Filling the drilling tools: Before the pipe bin is transported to the construction site, the drilling tools can be filled in advance. During work, the lifting member 201 is lifted to a certain height above the pipe bin frame 300, the drilling tools Z are transported to the upper side of the lifting member 201 by an external crane or manipulator, and the drilling tools Z are gently placed on the gripper 202 and the adjusting support plate 203. After the lifting member 201 receives the drilling tools Z, it is lowered to the horizontal height of the uppermost row of the conveying belt 101c or slightly higher. The adjusting support plate 203 near the conveying belt 101c is controlled to expand, so that the drilling tools Z roll along the adjusting support plate 203 to the first layer of the conveying belt 101c. Then, the adjusting support plate 203 is retracted, the lifting member 201 is lifted, and the second drilling tool below the crane or manipulator is received. The lifting member 201 continues to be lowered to the horizontal height of the uppermost row of the conveying belt 101c or slightly higher, and the conveying belt 101c is controlled to rotate a certain distance away from the lifting member 201, so that the first drilling tool Z moves and leaves a space for a drilling tool Z. The lifting member 201 places the second drilling tool Z on the conveying belt 101c, or uses the kinetic energy of the drilling tools Z rolling off the lifting member 201 to push away the first drilling tool Z. The conveying belt 101c and the lifting member 201 repeatedly perform the above operation. When the uppermost row of the conveying belt 101c is filled with drilling tools Z, the first row of drilling tools Z falls into the second row of placement layers 101 from the staggered position, and the process of filling the drilling tools Z is completed. As shown in FIG. Figure 3 The pipe bin is filled with drilling tools, which facilitates overall transportation.

[0057] The drill tool on the drilling rig: the drill pipe warehouse is carried to the construction site, and is placed at the target position directly below the mechanical arm of the drilling rig. During work, the lifting part 201 is controlled to descend to a position slightly lower than the lowermost layer of the conveying belt 101c. The conveying belt 101c is rotated towards the lifting part 201, so that the outermost drill tool Z rolls off above the gripper 202 on the top of the lifting part 201. The conveying belt 101c stops rotating, and the lifting part 201 supports the drill tool Z and lifts the drill pipe warehouse to a certain height. The mechanical arm above the drilling rig picks up the drill tool. The lifting part 201 always descends to the end position of the lowermost layer of the conveying belt 101c to receive the next drill tool Z. When the drill tools Z in the lowermost layer are all taken out, the conveying belt 101c in the previous placement layer 101 is controlled to arrange the drill tools Z from the staggered position to the lowermost layer of the placement layer 101. The previous taking-out action is repeated, and the drill tools Z on the lowermost layer of the conveying belt 101c are all taken out again. The above two processes are repeated until all the drill tools Z in the drill pipe warehouse are taken out.

[0058] When the drill tools Z in any drill pipe warehouse are completely taken out, the next drill pipe warehouse is replaced, and the construction continues.

[0059] Embodiment 3

[0060] With reference to Figure 6 and Fig. 9, the third embodiment of the utility model is different from the first and second embodiments in that the placement layers 101 also have other implementation structures. Specifically, each group of placement layers 101 is inclined and arranged, and at the distribution direction of the placement layers 101, one end is close to the end of the previous group of placement layers 101, and the other end is close to the end of the next group of placement layers 101. The end of the next group of placement layers 101 extends outside the end of the previous group of placement layers 101, and the vertical distance between the two is not less than the interval J.

[0061] In detail, each group of placement layers 101 is inclined and arranged, and the interval groups of placement layers 101 are parallel to each other. The inclined arrangement can make the drill tools Z placed on the surface roll under the action of gravity. The extension of the inclined end makes the adjacent groups of placement layers 101 communicate with each other, that is, the drill tools Z can roll from the placement layer 101 of the previous layer to the placement layer 101 of the next layer. This arrangement can simplify the control process of the storage structure 100 and the lifting assembly 200. And the storage structure 100 has only one placement opening (that is, the end of the top layer of the placement layer 101), and only one taking-out opening (that is, the end of the bottom layer of the placement layer 101).

[0062] Need to explain, this kind of implementation structure, need not to place the layer 101 set drive structure, its tilt design can use the gravity of drilling tool Z moves, further simplify the structure of storage structure 100. Among them, the inclination angle is as small as possible, can keep the drilling tool Z can produce rolling just can, this angle is not specifically defined, in order to keep the lowest layer of the placement layer 101 on the drilling tool Z does not occur off, can be set in its tilt down one end of the electric block D, and the drilling tool Z is taken out of position, that is, in the block D away from the other side of the placement layer 101.

[0063] On one side of all the placement layer 101, installed lifting assembly 200, for placing or taking out the drilling tool Z in each group of placement layer 101.

[0064] Specifically, lifting assembly 200 includes lifting piece 201 and setting at the top of the lifting piece 201 of the grab 202 and adjusting the branch plate 203, lifting piece 201 can be lifted and moved, change height, prior art, preferably hydraulic cylinder, through the top of the installed grab 202 and adjusting the branch plate 203 to lift the drilling tool Z, by controlling system changes the angle of adjusting the branch plate 203, can realize the limit or release of the drilling tool Z placed in the grab 202. In this embodiment, the lifting piece 201 for the drilling tool Z has only two places, greatly reduces the control difficulty.

[0065] The same as embodiment 1, 2, storage structure 100 and lifting assembly 200 can be installed on the platform frame on both sides of the power catwalk, also can be installed in the independent frame structure, the preferred scheme in this embodiment is in the pipe warehouse frame 300 of independent structure.

[0066] Pipe warehouse frame 300 is an independent frame structure, hollow inside, form has accommodation cavity M, the inner lining rod 101a of each group of placement layer 101 is fixed on the inner side wall of pipe warehouse frame 300, and as the hydraulic cylinder of lifting piece 201, the bottom is also fixed on the inner side wall of pipe warehouse frame 300, and the top surface of pipe warehouse frame 300 forms the entrance and exit of drilling tool Z, convenient for the drilling tool Z to take and place.

[0067] Further, this embodiment in the process of use, can put into the drilling tool Z in the storage structure 100 in the pipe warehouse frame 300, and take out the drilling tool Z, the process is described as follows:

[0068] The drill pipe bin can be filled with drilling tools in advance before being transported to the construction site. The lifting member 201 is lifted from the accommodating cavity M to a certain height above the pipe bin frame 300. An external crane or manipulator is used to transport the drilling tool Z to the upper side of the lifting member 201, and the drilling tool Z is gently placed on the gripper 202 and the adjusting support plate 203. After the lifting member 201 receives the drilling tool Z, the lifting member 201 is lowered to the horizontal height of the uppermost row of the placing layer 101 or a position slightly higher than the horizontal height. The adjusting support plate 203 near the placing layer 101 is controlled to be unfolded, so that the drilling tool Z rolls along the adjusting support plate 203 to the placing layer 101 of the first layer. The drilling tool Z rolls on the inclined placing layer 101 and continues to the inclined end of the lowermost placing layer 101. Then, the adjusting support plate 203 is retracted, the lifting member 201 is lifted, and the second drilling tool Z below the crane or manipulator is received. The lifting member 201 continues to be lowered to the horizontal height of the uppermost row of the conveying belt 101c or a position slightly higher than the horizontal height. The adjusting support plate 203 is opened again, and the second drilling tool Z is released to the placing layer 101 of the top layer. The operation is continuously repeated until all the layers of the placing layer 101 are filled, and the filling process of the drilling tool Z is completed. As shown in FIG. Figure 3 The drill pipe bin is helpful for overall transportation after the filling of the drilling tools is completed.

[0069] The drilling tool upper drilling platform: The drill pipe bin is transported to the construction site and placed at the target position directly below the manipulator at the side of the drilling platform. In operation, the lifting member 201 is controlled to be lowered to a position slightly lower than the lowermost layer of the placing layer 101 and located at one side of the stop block D. The stop block D is controlled to be moved away, and the outermost drilling tool Z rolls onto the gripper 202 on the top of the lifting member 201. The stop block D is controlled to be reset to block the next drilling tool Z. The lifting member 201 supports the drilling tool Z and lifts the drill pipe bin to a certain height. The manipulator above the drilling platform grabs the drilling tool Z. The lifting member 201 is lowered again to the end position of the lowermost layer of the placing layer 101 to receive the next drilling tool Z. The previous taking-out operation is repeated until all the drilling tools Z in the drill pipe bin are taken out.

[0070] When the drilling tools Z in any drill pipe bin are completely taken out, the next drill pipe bin is replaced, and the construction is continued.
