Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and in particular to a palletizing and depalletizing device, a palletizing method, and a depalletizing method. Background Technology

[0002] In oil and gas well drilling operations, drill strings not only perform the core functions of breaking rocks and deepening the wellbore, but also bear the important task of transporting drilling fluid, making them indispensable key equipment in drilling operations. At the drilling site, drill strings need to be arranged logically to maximize the use of working space. Especially when dealing with different formations and drilling conditions, frequent changes in drill string types are often required. In such cases, an orderly drill string stacking layout can significantly shorten changeover time and improve overall drilling efficiency.

[0003] Currently, the stacking of drilling tools mainly relies on manual operation, where workers use forklifts, crowbars, and other tools to move, stack, and unstack the tools. However, manual stacking or unstacking requires multiple workers to work together, consuming a significant amount of time and manpower, resulting in low efficiency. Moreover, during the stacking and unstacking process, workers need to frequently move heavy drilling tools, which not only increases labor intensity but also raises the risk of safety accidents. Furthermore, manual stacking makes it difficult to ensure the standardization and neatness of the stacks, easily creating safety hazards.

[0004] Therefore, there is an urgent need for a palletizing and depalletizing device, a palletizing method, and a depalletizing method to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a palletizing and depalletizing device, a palletizing method, and a depalletizing method, which significantly reduces the time and manpower consumed in palletizing and depalletizing, improves the efficiency of palletizing and depalletizing, reduces the risk of safety accidents, and improves the standardization and neatness of stacking.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] In a first aspect, a stacking and destacking device is provided for stacking and / or destacking drilling tools, comprising:

[0008] The stacking rack is height-adjustable and has an enclosed space where multiple drilling tools can be stacked.

[0009] A feeding assembly is provided at the feeding end of the palletizing frame. The feeding assembly includes a vertically inclined guide frame, and the drill bit can be moved down from the end of the guide frame away from the palletizing frame to the end of the guide frame close to the palletizing frame.

[0010] Several operating mechanisms are provided, which are located between the palletizing frame and the guide frame and / or at the discharge end of the palletizing frame. Each operating mechanism includes two operating carriages arranged at intervals along a preset direction. Each operating carriage includes a first support, a drive assembly, and an operating assembly. Both the operating assembly and the drive assembly are located on the first support. The output end of the drive assembly is connected to the operating assembly and is used to drive the operating assembly to move along the vertical direction, the material conveying direction, and the preset direction. The operating assembly can support the drill bit. The preset direction is the extension direction of the drill bit, and the material conveying direction is set at an angle to the preset direction.

[0011] Optionally, the palletizing rack includes a stacking platform and a detachable enclosure assembly disposed on the stacking platform. The enclosure assembly forms an enclosure space. The enclosure assembly includes multiple enclosure members arranged continuously in a vertical direction, and any two adjacent enclosure members are interlocked. An operating component can clamp the enclosure members.

[0012] Optionally, the drive assembly includes a first drive member, a second drive member, and a third drive member, and the operating assembly includes a second bracket, a third bracket, and a support member. The second bracket and the first drive member are both disposed on the first bracket, the second drive member and the third bracket are both disposed on the second bracket, and the third drive member and the support member are both disposed on the third bracket. The support member can support the drill bit. The output end of the first drive member is connected to the second bracket and is used to drive the second bracket to move the support member vertically through the third bracket. The output end of the second drive member is connected to the third bracket and is used to drive the third bracket to move the support member along a preset direction. The output end of the third drive member is connected to the support member and is used to drive the support member to move along the material conveying direction.

[0013] Optionally, the support is provided with a rotatable limiting member, which has a limiting state and a conveying state. In the limiting state, the limiting member rotates at least partially to the top of the support and can contact the drill bit. In the conveying state, the limiting member rotates to the bottom of the top surface of the support.

[0014] Optionally, the feeding assembly also includes a buffer frame disposed between the guide frame and the stacking frame. The buffer frame extends along the feeding direction and is connected to the guide frame. A first blocking member that is movable along the feeding direction is provided at the end of the buffer frame away from the guide frame.

[0015] Optionally, the buffer frame includes a first frame, a first elastic vibrating element, and a first buffer platform. The first elastic vibrating element is disposed on the first frame, and the first buffer platform is movably disposed on the first frame and connected to the first elastic vibrating element. The first blocking element is movably disposed on the first buffer platform along the material conveying direction. When the drill bit moves from the guide frame to the first buffer platform, the first buffer platform can vibrate up and down under the elastic force of the first elastic vibrating element.

[0016] Optionally, the discharge end of the palletizing frame is provided with a second buffer platform, and the end of the second buffer platform away from the palletizing frame is provided with a second blocking member that can move along the conveying direction.

[0017] Optionally, the guide frame is provided with a third blocking element at both ends along the preset direction, and the drill bit can be limited to the two third blocking elements along the preset direction.

[0018] Secondly, a palletizing method is provided, which uses the palletizing and depalletizing device of the first aspect to palletize drilling tools. The feeding end of the palletizing frame is equipped with an operating mechanism, or both the feeding end and the discharging end of the palletizing frame are equipped with operating mechanisms. The palletizing method includes the following steps:

[0019] S1. Place the drill bit to be stacked at the end of the guide frame away from the stacking frame;

[0020] S2. Adjust the height of the stacking rack so that the drill tools to be stacked can be placed within the enclosure space;

[0021] S3. Use the drive component to drive the operating component to move along the feeding direction, the preset direction and / or the vertical direction until the operating component moves to the bottom of the drill bit located on the feeding component;

[0022] S4. Drive the operating components of the two operating vehicles to move simultaneously along the material conveying direction, the vertical direction and / or the preset direction until the operating components drive the supported drill bit to be stacked in the enclosure space.

[0023] S5. Repeat steps S2 to S4 until all drilling tools to be stacked are placed in the containment space.

[0024] Thirdly, a destacking method is provided, wherein the discharge end of the stacking rack is equipped with an operating mechanism, or both the infeed end and the discharge end of the stacking rack are equipped with operating mechanisms. The destacking method includes the following steps:

[0025] P1. Use the drive component to drive the operating component to move along the material conveying direction, the preset direction and / or the vertical direction until the operating component moves to the bottom of the drill bit to be moved within the enclosure space;

[0026] P2. The operating components of the two operating vehicles move simultaneously along the material conveying direction, the preset direction and / or the vertical direction. The two operating components drive the drill bit to move simultaneously until the drill bit is taken out of the enclosure space.

[0027] P3. Adjust the height of the palletizing rack;

[0028] P4. Repeat steps P1 to P3 until all drill bits to be unpacked are removed from the containment space.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] This invention provides a stacking and destacking device, a stacking method, and a destacking method. When the drill bit is placed on the feeding assembly, a vertically inclined guide frame can guide the drill bit to automatically move from the end away from the stacking frame to the end closer to the stacking frame, realizing automatic feeding of the drill bit on the guide frame and improving the automation level of conveying the drill bit to the stacking frame. When the operating mechanism is set at the feeding end of the stacking frame, the operating mechanism can be used to stack the drill bit. That is, by driving the operating component to move along the vertical direction, the feeding direction, and the preset direction, it can be gradually moved closer to the drill bit located on the feeding assembly and moved to the bottom of the drill bit to support it. Subsequently, driving the operating component to move it can move the supported drill bit together, so as to move the drill bit into the enclosure space and stack it in a suitable position. When the operating mechanism is located at the discharge end of the stacking frame, it can be used for unstacking drill bits. By driving the operating component to move vertically, in the conveying direction, and in a preset direction, it gradually approaches the drill bit located on the stacking frame and moves it to the bottom of the drill bit to be unstacking, thus supporting it. Subsequently, driving the operating component moves it, allowing the supported drill bit to move together and be removed from the enclosed space. Two operating carts are spaced apart along a preset direction, allowing the operating components of each cart to support both ends of the drill bit, ensuring stability during movement. Adjusting the height of the stacking frame allows multiple drill bits moved into the enclosed space to be protected, preventing movement after stacking and improving stability, thus ensuring safety at the stacking site. Furthermore, continuously adjusting the height of the stacking frame during stacking and unstacking helps prevent collisions between the stacking frame, operating components, and drill bits, ensuring not only smooth stacking and unstacking but also safety during both processes. Compared with existing technologies, the stacking and destacking device provided by this invention eliminates the need for workers to handle drilling tools during stacking and destacking, significantly reducing the time and manpower consumed in stacking and destacking, improving the efficiency of drilling tool stacking and destacking, and reducing the risk of safety accidents. Moreover, the use of the stacking and destacking device can also improve the automation level of drilling tool stacking and destacking, helping to ensure the standardization and neatness of drilling tool stacking and reducing safety hazards in drilling tool stacking.

[0059] Example 1

[0060] like Figures 1 to 16 As shown, this embodiment provides a palletizing and depalletizing device, which significantly reduces the time and manpower consumed in palletizing and depalletizing, improves the efficiency of palletizing and depalletizing, reduces the risk of safety accidents, and improves the standardization and neatness of stacking.

[0061] See Figure 1 and Figure 2 The stacking and destacking device is used for stacking and / or destacking drilling tools 100. It includes a stacking frame 1, a feeding assembly 2, and several operating mechanisms. The height of the stacking frame 1 is adjustable, and a protective space 11 is provided on the stacking frame 1, within which multiple drilling tools 100 can be stacked. The feeding assembly 2 is located at the feeding end of the stacking frame 1 and includes a vertically inclined guide frame 21. The drilling tool 100 can be moved from the end of the guide frame 21 away from the stacking frame 1 to the end of the guide frame 21 close to the stacking frame 1. The operating mechanisms are located between the stacking frame 1 and the guide frame 21 and / or at the discharge end of the stacking frame 1. The operating mechanisms include two mechanisms operating along a preset direction (…). Figure 1 The operating vehicle 3 is arranged at intervals in the Y direction. The operating vehicle 3 includes a first bracket 31, a drive assembly 32, and an operating assembly 33. Both the operating assembly 33 and the drive assembly 32 are mounted on the first bracket 31. The output end of the drive assembly 32 is connected to the operating assembly 33 and is used to drive the operating assembly 33 in the vertical direction. Figure 1 Z-direction), conveying direction ( Figure 1The operating component 33 can support the drill bit 100 by moving in the X direction and the preset direction. The preset direction is the extension direction of the drill bit 100, and the material conveying direction is set at an angle to the preset direction.

[0062] The stacking and destacking device provided in this embodiment allows the drill bit 100 to be automatically moved from the end furthest from the stacking frame 1 to the end closest to the stacking frame 1 when the drill bit 100 is placed on the feeding assembly 2. This enables automatic feeding of the drill bit 100 onto the guide frame 21 and improves the automation level of conveying the drill bit 100 to the stacking frame 1. When the operating mechanism is located at the feeding end of the stacking frame 1, it can be used to stack the drill bit 100. That is, by driving the operating assembly 33 to move along the vertical direction, the feeding direction, and the preset direction, it can gradually move the drill bit 100 located on the feeding assembly 2 and move it to the bottom of the drill bit 100 to support it. Subsequently, by driving the operating assembly 33 to move, the operating assembly 33 can move the supported drill bit 100 together to move the drill bit 100 into the enclosure space 11 and stack it in a suitable position. When the operating mechanism is located at the discharge end of the stacking rack 1, it can be used to unstack the drill bit 100. Specifically, by driving the operating component 33 to move along the vertical direction, the conveying direction, and a preset direction, it can gradually approach the drill bit 100 located on the stacking rack 1 and move it to the bottom of the drill bit 100 to be unstacked, thus supporting the drill bit 100. Subsequently, driving the operating component 33 to move it can move the supported drill bit 100 together, thereby removing the drill bit 100 from the enclosure space 11. Two operating carts 3 are arranged at intervals along a preset direction, so that the operating components 33 of the two operating carts 3 can respectively support both ends of the drill bit 100, ensuring the stability of the drill bit 100 during movement. By adjusting the height of the stacking frame 1, multiple drilling tools 100 moved into the enclosed space 11 can be protected by the stacking frame 1, preventing the drilling tools 100 from moving after stacking, improving the stability of the drilling tools 100 after stacking, and ensuring the safety of the stacking site. Moreover, by continuously adjusting the height of the stacking frame 1 during the stacking and unstacking process, it helps to prevent the stacking frame 1 from colliding with the operating components 33 and the drilling tools 100, ensuring not only the smooth stacking and unstacking of the drilling tools 100, but also the safety of the stacking and unstacking process. Compared with the prior art, the stacking and destacking device provided in this embodiment eliminates the need for workers to handle the drilling tools 100 during stacking and destacking, significantly reducing the time and manpower consumed in stacking and destacking, improving the efficiency of stacking and destacking the drilling tools 100, and reducing the risk of safety accidents. Moreover, the use of the stacking and destacking device can also improve the automation level of stacking and destacking the drilling tools 100, helping to ensure the standardization and neatness of the stacking of the drilling tools 100, and reducing the safety hazards of stacking the drilling tools 100.

[0063] For example, see Figure 1The feeding direction, preset direction and vertical direction are perpendicular to each other; both the feeding end and the discharge end of the stacking rack 1 are equipped with operating mechanisms.

[0064] In this embodiment, see Figure 2 The bottom of the first support 31 is provided with a walking component 311 to facilitate the movement of the operating vehicle 3 by the staff; moreover, when the maximum movement distance of the operating component 33 on the first support 31 is limited, the staff can move the operating component 33 by moving the operating vehicle 3 as a whole, which improves the flexibility of the movement of the operating component 33.

[0065] For example, the walking component 311 uses casters, which allows the operating vehicle 3 to move in any direction.

[0066] Furthermore, the traveling component 311 is equipped with a brake. When the operating vehicle 3 moves to a suitable position, the traveling component 311 can be braked by the brake, so that the operating vehicle 3 remains stationary in the current position. When it is necessary to move the operating vehicle 3, the traveling component 311 can be resumed to move simply by releasing the brake.

[0067] Optionally, see Figure 2 , Figure 3 and Figure 4 The stacking rack 1 includes a stacking platform 12 and a detachable enclosure component 13 disposed on the stacking platform 12. The enclosure component 13 encloses and forms an enclosure space 11. The enclosure component 13 includes a plurality of enclosure members 131 arranged continuously in the vertical direction, and any two adjacent enclosure members 131 are interlocked. An operating component 33 can clamp the enclosure members 131. When the enclosure component 13 is connected to the stacking platform 12, the enclosure component 13 can protect the stacked drilling tool 100 and restrict the movement of the drilling tool 100. When it is not necessary to stack the drilling tool 100, the enclosure component 13 can be separated from the stacking platform 12, allowing workers to enter the stacking platform 12 to carry out other work, thereby improving the space utilization rate of the construction site. The operating component 33 can clamp the protective member 131, causing the driving operating component 33 to move the clamped protective member 131 to the top of the stacking platform 12. Connecting the clamped protective member 131 to the top of the stacking platform 12 increases the height of the palletizing rack 1. Conversely, moving the operating component 33 to clamp the top protective member 131 and then removing it from the stacking platform 12 decreases the height of the palletizing rack 1. This not only improves the versatility of the operating component 33 but also reduces the number of parts used in the palletizing and depalletizing device. Furthermore, the vertical insertion between adjacent protective members 131 reduces the difficulty for operators to connect or disconnect two protective members 131 by controlling the operating component 33.

[0068] In this embodiment, see Figure 3 and Figure 4 The containment component 13 extends along the material conveying direction and is provided in two sets. The two sets of containment components 13 are respectively located at both ends of the stacking platform 12 along the preset direction. The two ends of the drill bit 100 stacked in the containment space 11 are respectively mounted on the containment components 131 on both sides.

[0069] Further, see Figure 2 , Figure 3 and Figure 5 The enclosure 131 is provided with a stacking groove 1311. The bottom wall of the stacking groove 1311 near the feeding component 2 is provided with a vertically inclined feeding ramp 1312. When the operating component 33 places the drill 100 into the stacking groove 1311, the drill 100 can automatically roll along the feeding ramp 1312 to the bottom wall of the stacking groove 1311. This allows the operating component 33 to support the drill 100 at the feeding end of the stacking frame 1 during stacking. During destacking, the operating component 33 can support the drill 100 to be destacking at the discharge end of the stacking frame 1. The operating component 33 does not need to move along the conveying direction within the enclosure space 11, which improves the efficiency of stacking the drill 100. Moreover, the wall of the stacking groove 1311 can restrict the movement of the drill 100 in the conveying direction, so that after the drill 100 located at the discharge end is removed by the operating component 33 during destacking, the drill 100 in the stacking groove 1311 will not roll off the stacking frame 1 due to the reduced support force on the side near the discharge end, thus ensuring safety during destacking.

[0070] For example, enclosure 131 uses a pad bar.

[0071] In other embodiments, the enclosure component 13 extends circumferentially along the stacking platform 12, or the cross-sectional shape of the enclosure component 13 is U-shaped.

[0072] In this embodiment, see Figure 5 and Figure 6 The top surface of the enclosure 131 is provided with a first slot 1313, and the bottom surface of the enclosure 131 is provided with a plug-in part 1314. The plug-in part 1314 of the enclosure 131 can be inserted into the first slot 1313 of the enclosure 131 located below and adjacent to it, so as to realize the quick and stable connection of the two adjacent enclosures 131.

[0073] For example, see Figure 2 , 4 and Figure 5Two sets of enclosure components 13 are spaced apart along a preset direction. The enclosure member 131 extends along the material conveying direction, and both ends of the enclosure member 131 along its extension direction are provided with a plug-in part 1314 and a first slot 1313, so that both ends of the enclosure member 131 along its extension direction can be connected to the adjacent enclosure member 131, ensuring the stability of the enclosure member 131 installed on the stacking platform 12. The feeding end and the discharging end of the stacking rack 1 are preferably provided with an operating mechanism, and the two operating carts 3 of the operating mechanism are respectively collinear with the two enclosure components 13. When the enclosure member 131 is moved, the operating components 33 of the two operating carts 3 at both ends of the enclosure member 131 respectively clamp the two ends of the enclosure member 131 to ensure the stability of the movement of the enclosure member 131.

[0074] Further, see Figure 4 , Figure 7 and Figure 8 The stacking platform 12 is provided with a second slot 121. The insertion part 1314 of the lowermost protective member 131 can be inserted into or detached from the second slot 121 to achieve a detachable connection between the protective assembly 13 and the stacking platform 12. That is, when the insertion part 1314 of the lowermost protective member 131 is inserted into the second slot 121, the protective assembly 13 is connected to the stacking platform 12; when the protective assembly 13 is detached from the second slot 121, the protective assembly 13 is separated from the stacking platform 12.

[0075] Further, see Figure 4 , Figure 7 and Figure 8 The bottom enclosure 131 is provided with a threaded hole 1315, and the second slot 121 is provided with a connecting hole 1211 on the slot wall. The stacking and destacking device also includes fasteners (not shown in the figure). When the insertion part 1314 of the bottom enclosure 131 is inserted into the second slot 121, the threaded hole 1315 communicates with the connecting hole 1211. The fastener can pass through the connecting hole 1211 and be threadedly connected to the threaded hole 1315 to enhance the stability of the connection between the bottom enclosure 131 and the stacking platform 12.

[0076] For example, the fastener is a bolt.

[0077] Optionally, see Figure 1 and Figure 2The drive assembly 32 includes a first drive member (not shown in the figure), a second drive member 321, and a third drive member 322. The operation assembly 33 includes a second bracket 331, a third bracket 332, and a support member 333. The second bracket 331 and the first drive member are both disposed on the first bracket 31. The second drive member 321 and the third bracket 332 are both disposed on the second bracket 331. The third drive member 322 and the support member 333 are both disposed on the third bracket 332. The support member 333 can support the drill bit 100. The output end of the first drive member is connected to the second bracket 331 and is used to drive the second bracket 331 to drive the support member 333 to move vertically through the third bracket 332. The output end of the second drive member 321 is connected to the third bracket 332 and is used to drive the third bracket 332 to drive the support member 333 to move along a preset direction. The output end of the third drive member 322 is connected to the support member 333 and is used to drive the support member 333 to move along the material conveying direction. This configuration allows the support member 333 to support the drill string 100 to move in any of the following directions: vertical, conveying, or preset, in order to complete the stacking and unstacking of the drill string 100.

[0078] Specifically, see Figure 11 The first support 31 is provided with a first slide rail 312 extending vertically, and the second support 331 is provided with a first roller 3311. When the first driving member drives the second support 331 to move, the first roller 3311 rolls on the first slide rail 312 to reduce the friction between the second support 331 and the first support 31, reduce the energy consumed by the first driving member, and increase the moving speed of the second support 331. (See reference...) Figure 10 The second support 331 is provided with a second slide rail 3312 extending in a preset direction, and the third support 332 is provided with a second roller 3321 that slides in cooperation with the second slide rail 3312. When the second driving member 321 drives the roller to move, the second roller 3321 rolls on the second slide rail 3312 to reduce the friction between the third support 332 and the second support 331, reduce the energy consumed by the second driving member 321, and increase the moving speed of the third support 332. (See reference...) Figure 2 The third support 332 is provided with a third slide rail 3322 extending along the material conveying direction, and the support member 333 is provided with a third roller 3331. When the third drive member 322 drives the support member 333 to move, the third roller 3331 rolls on the third slide rail 3322 to reduce the friction between the third support 332 and the support member 333, reduce the energy consumed by the third drive member 322, and increase the moving speed of the support member 333.

[0079] Further, see Figure 1 and Figure 10The first support 31 includes a slidably connected base 313 and a sliding frame 314. The second support 331 is movably mounted on the sliding frame 314. A fourth driving member is also provided on the base 313. The output end of the fourth driving member is connected to the sliding frame 314 and is used to drive the sliding frame 314 to slide vertically relative to the base 313. This arrangement increases the vertically movable distance of the second support 331, so that when the drill bits 100 stacked on the stacking rack 1 are high, the operating mechanism can still continue to stack the drill bits 100.

[0080] For example, the first drive member, the second drive member 321, the third drive member 322 and the fourth drive member are all hydraulic cylinders.

[0081] In this embodiment, see Figure 1 and Figure 2 The support member 333 is provided with a vertically inclined support slope 3332, which extends along the material conveying direction to support the drill bit 100 and enable the drill bit 100 to move automatically in the direction to be placed on the support member 333.

[0082] Specifically, see Figure 1 and Figure 2 When the operating mechanism is located at the feeding end of the stacking frame 1, the height of the end of the supporting inclined surface 3332 near the feeding component 2 is higher than the height of the end of the supporting inclined surface 3332 near the stacking frame 1, so that the drill 100 can automatically move on the support 333 towards the stacking frame 1, facilitating the stacking of the drill 100. When the operating mechanism is located at the discharge end of the stacking frame 1, the height of the end of the supporting inclined surface 3332 near the stacking frame 1 is higher than the height of the end of the supporting inclined surface 3332 away from the stacking frame 1, so that the drill 100 can automatically move on the support 333 away from the stacking frame 1, facilitating the destacking of the drill 100.

[0083] In this embodiment, see Figure 2 and Figure 4 The support 333 is provided with a clamping part 3333 at one end near the stacking rack 1, and the clamping part 3333 is configured to clamp the protective member 131.

[0084] Specifically, see Figure 2 and Figure 6 The enclosure 131 extends along the material conveying direction. The two side walls of the enclosure 131 facing each other along the preset direction are provided with clamping grooves 1316. The clamping part 3333 includes two clamping arms spaced apart along the preset direction. The two clamping arms can be inserted into the two clamping grooves 1316 respectively. The groove wall of the clamping groove 1316 can restrict the movement of the clamping arms along the vertical direction and the preset direction, so that the support 333 can stably clamp the enclosure 131.

[0085] In this embodiment, see Figure 1 , Figure 10 and Figure 12 The support member 333 is provided with a rotatable limiting member 334. The limiting member 334 has a limiting state and a conveying state. In the limiting state, the limiting member 334 rotates at least partially to the top of the support member 333, and the limiting member 334 can contact the drill bit 100 to limit the drill bit 100 on the support member 333, so as to prevent the drill bit 100 from moving during the supporting process or even falling off the support member 333, which would threaten the safety of the construction site. In the conveying state, the limiting member 334 rotates to the bottom of the top surface of the support member 333, and the movement of the drill bit 100 on the support member 333 is no longer restricted, so that the drill bit 100 can be moved from the support member 333 to the stacking rack 1 or from the stacking rack 1 to other structures.

[0086] Further, see Figure 10 and Figure 12 The support member 333 is also provided with a fifth driving member 335. The output end of the fifth driving member 335 is connected to the limiting member 334 and is used to drive the limiting member 334 to rotate so that the limiting member 334 can switch between the limiting state and the conveying state.

[0087] For example, the fifth drive element 335 is an electric actuator.

[0088] Optionally, see Figure 1 , Figure 2 and Figure 13The feeding assembly 2 also includes a buffer frame 22 disposed between the guide frame 21 and the stacking frame 1. The buffer frame 22 extends along the feeding direction and is connected to the guide frame 21. A first blocking member 2231 movable along the feeding direction is provided at the end of the buffer frame 22 away from the guide frame 21. The number of drill bits 100 that the operating assembly 33 can move at one time is limited. When multiple drill bits 100 are placed on the guide frame 21, the multiple drill bits 100 can be moved from the guide frame 21 to the buffer frame 22 to wait for the operating assembly 33 to move. This allows the operator to either feed multiple drill bits 100 to the feeding assembly 2 first and then move the multiple drill bits 100 from the feeding assembly 2 to the stacking frame 1, or feed one drill bit 100 to the feeding assembly 2 and then move that drill bit 100 to the stacking frame 1, thus improving the mobility during stacking. The guide frame 21 is vertically tilted, causing the drill bit 100 moving onto the buffer frame 22 to have a certain acceleration. It will still move a certain distance along the conveying direction on the buffer frame 22. At this time, the first blocking member 2231 can limit the maximum distance the drill bit 100 can move on the buffer frame 22, preventing it from falling off. Furthermore, when the guide frame 21 conveys multiple drill bits 100 onto the buffer frame 22, the first blocking member 2231 can also prevent drill bits 100 that move later onto the buffer frame 22 from pushing against drill bits 100 that moved earlier and falling off. When conveying different numbers of drill bits 100 onto the buffer frame 22, the buffer distance that the drill bit 100 can be buffered on the buffer frame 22 can be changed by moving the position of the first blocking member 2231, thus improving the applicability of the buffer frame 22.

[0089] For example, the first blocking member 2231 is a baffle.

[0090] In this embodiment, see Figure 1 , Figure 2 and Figure 13The buffer frame 22 includes a first frame 221, a first elastic vibrating element 222, and a first buffer platform 223. The first elastic vibrating element 222 is disposed on the first frame 221, and the first buffer platform 223 is movably disposed on the first frame 221 and connected to the first elastic vibrating element 222. A first blocking element 2231 is movably disposed on the first buffer platform 223 along the material conveying direction. When the drill bit 100 moves from the guide frame 21 onto the first buffer platform 223, the first buffer platform 223 can vibrate up and down under the elastic force of the first elastic vibrating element 222. At the instant the drill bit 100 moves onto the first buffer platform 223, the first buffer platform 223 will be subjected to a large pressure. This pressure causes the first buffer platform 223 to move or rotate. At this time, the first elastic vibrating element 222 deforms, and the elastic force of the first elastic vibrating element 222 acts in the opposite direction on the first buffer platform 223, thereby enabling the first buffer platform 223 to vibrate up and down. The first buffer platform 223 vibrates up and down, which enables relative movement between the multiple drill bits 100 located on it, thereby effectively preventing the rod-shaped drill bits 100 from stacking on the first buffer platform 223, so that the operating component 33 can move the drill bits 100 on the first buffer platform 223.

[0091] Specifically, see Figure 1 , Figure 13 and Figure 14 The first buffer platform 223 includes multiple first buffer beams 2232 arranged at intervals along a preset direction. Multiple first blocking members 2231 are provided, each corresponding to one of the multiple first buffer beams 2232. The end of each first buffer beam 2232 near the guide frame 21 is rotatably connected to the first frame 221. At least a portion of the first buffer beams 2232 have a first elastic vibrating member 222 at the end away from the guide frame 21. When the drill bit 100 moves onto the first buffer platform 223, the end of the first buffer beam 2232 near the guide frame 21 rotates under the weight of the drill bit 100, and the end of the first buffer beam 2232 away from the guide frame 21 moves downward, causing the corresponding first elastic vibrating member 222 to deform. The first buffer beam 2232 is provided with a first chute extending along the material conveying direction, and the first blocking member 2231 is provided with a first sliding part that slides into the first chute, allowing the first blocking member 2231 to move on the corresponding first buffer beam 2232.

[0092] For example, the first elastic vibrating element 222 is a spring.

[0093] Optionally, see Figure 1 , Figure 2 and Figure 16The discharge end of the stacking rack 1 is equipped with a second buffer platform 42, and the end of the second buffer platform 42 away from the stacking rack 1 is equipped with a second blocking member 41 that is movable along the conveying direction. During destabilization, the operating component 33 moves the drill bit 100 from the stacking rack 1 to the second buffer platform 42, where multiple drill bits 100 can be placed for subsequent use. The second blocking member 41 can prevent the drill bit 100 from falling off the buffer rack 22, ensuring the safety of the construction site.

[0094] Specifically, see Figure 16 The second buffer platform 42 includes multiple second buffer beams 421 arranged at intervals along a preset direction. Multiple second blocking members 41 are provided, each corresponding to one of the multiple second buffer beams 421. Each second buffer beam 421 is provided with a second chute extending along the material conveying direction. Each second blocking member 41 is provided with a second sliding part that slides in cooperation with the second chute, allowing the second blocking member 41 to move on the corresponding second buffer beam 421.

[0095] For example, the second blocking member 41 is a baffle.

[0096] Optionally, see Figure 1 , Figure 2 and Figure 13 The guide frame 21 is provided with a third blocking member 211 at both ends along the preset direction. The drill bit 100 can be limited between the two third blocking members 211 along the preset direction, so that the two ends of the multiple drill bits 100 passing through the guide frame 21 can be aligned. Thus, when the operating component 33 moves the drill bit 100 to the stacking frame 1, it does not need to move along the preset direction to ensure the neatness of the multiple drill bits 100 after they are stacked on the stacking frame 1, which improves the efficiency of the drill bit 100 stacking and reduces the difficulty of the drill bit 100 stacking.

[0097] In this embodiment, please refer to the figure. Figure 1 , Figure 13 and Figure 1 The guide frame 21 includes a second frame 212 and multiple guide beams 213 disposed on the top of the second frame 212. The multiple guide beams 213 are arranged at intervals along a preset direction. The height of the end of the guide beam 213 away from the stacking rack 1 is higher than the height of the end of the guide beam 213 close to the stacking rack 1. A third blocking member 211 is disposed on the outermost guide beam 213.

[0098] Furthermore, the lengths of the enclosure space 11 and the buffer frame 22 along the preset direction are the same as the length of the drill string 100, and the distance between the two third blocking members 211 along the preset direction is also the same as the length of the drill string 100. This ensures that when the drill string 100 is placed on the guide frame 21, it is already aligned with the enclosure space 11 along the preset direction. Therefore, during the subsequent movement of the drill string 100 supported by the operating component 33, it is not necessary to drive the operating component 33 to move along the preset direction, which reduces the steps of driving the operating component 33 to move and improves the convenience and efficiency of stacking the drill string 100.

[0099] Further, see Figure 1 and Figure 15 At least a portion of the guide beam 213 is provided with a second elastic vibrating element 214 at the end away from the buffer frame 22. The guide beam 213 can vibrate up and down under the elastic force of the second elastic vibrating element 214 to avoid the drill bit 100 from stacking on the guide beam 213.

[0100] For example, the third blocking member 211 is a baffle.

[0101] Example 2

[0102] like Figure 17 As shown, this embodiment provides a palletizing method, using the palletizing and depalletizing device of Embodiment 1 to palletize the drill bit 100. The feeding end of the palletizing frame 1 is provided with an operating mechanism, or both the feeding end and the discharging end of the palletizing frame 1 are provided with operating mechanisms. The palletizing method includes the following steps:

[0103] S1. Place the drill bit 100 to be stacked on the guide frame 21 at the end away from the stacking frame 1.

[0104] Specifically, after the drill bit 100 is placed on the end of the guide frame 21 away from the stacking frame 1, the drill bit 100 will automatically roll along the vertically inclined guide frame 21 from the end away from the stacking frame 1 to the end of the guide frame 21 close to the stacking frame 1, and move to the first buffer platform 223 under the action of inertia. Subsequently, the first blocking member 2231 or the drill bit 100 that has moved to the first buffer platform 223 will prevent the drill bit 100 that has just moved to the first buffer platform 223 from continuing to move; at the same time, the first elastic vibrating member 222 deforms, and the first buffer platform 223 drives several drill bits 100 that have moved to it to vibrate up and down under the elastic force of the first elastic vibrating member 222, so as to avoid the drill bits 100 from stacking on the first buffer platform 223.

[0105] S2. Adjust the height of the stacking frame 1 so that the drill bit 100 to be stacked can be placed in the enclosure space 11, preventing the stacked drill bit 100 from moving in the enclosure space 11. At the same time, it also helps to avoid the stacking frame 1 from affecting the operation component 33 in placing the drill bit 100 in the enclosure space 11.

[0106] Specifically, the support member 333 is driven to move until the clamping part 3333 of the support member 333 moves to the enclosure member 131 to be installed, and the two clamping arms of the clamping part 3333 are respectively inserted into the two clamping slots 1316 of the enclosure member 131 to be installed; then, the support member 333 is driven to move, and the support member 333 clamps the enclosure member 131 to be installed and moves it to the enclosure member 131 already installed on the palletizing platform; next, the support member 333 is driven to move until the support member 333 drives the insertion part 1314 of the enclosure member 131 it clamps to be inserted into the first slot 1313 of the enclosure member 131 located at the top of the palletizing platform, so as to complete the raising of the height of the palletizing frame 1 to accommodate the continuous increase of the drill bit 100 in the enclosure space 11 during palletizing.

[0107] S3. The operating component 33 is driven by the driving component 32 to move along the feeding direction, the preset direction, and / or the vertical direction until the operating component 33 moves to the bottom of the drill bit 100 located on the feeding component 2. At this time, the support member 333 of the operating component 33 can support the drill bit 100, so that the subsequent movement of the support member 333 can drive the drill bit 100 to move together.

[0108] S4. The operating components 33 of the two operating vehicles 3 move simultaneously along the material conveying direction, the vertical direction and / or the preset direction until the operating components 33 drive the drill bit 100 supported by them to be stacked in the enclosure space 11.

[0109] In this embodiment, since the lengths of the enclosure space 11 and the buffer frame 22 along the preset direction are the same as the length of the drill bit 100, the support member 333 does not need to move along the preset direction to adjust the stacking position of the drill bit 100; it only needs to move along the material conveying direction and the vertical direction. Specifically, when the support member 333 supports the drill bit 100 away from the buffer frame 22, under the influence of the first blocking member 2231, the support member 333 first supports the drill bit 100 to move upward, and then supports the drill bit 100 to move along the material conveying direction; when the drill bit 100 moves to the stacking frame 1, the support member 333 is driven to support the drill bit 100 to move along the material conveying direction and / or the vertical direction to stack the drill bit 100 on the stacking platform 12 or on the drill bit 100 already stacked in the enclosure space 11.

[0110] S5. Repeat steps S2 to S4 until all drilling tools 100 to be stacked are placed in the enclosure space 11.

[0111] Example 3

[0112] like Figure 18As shown, this embodiment provides a destacking method, using the destacking drill 100 of the stacking and destacking device of Embodiment 1. The discharge end of the stacking frame 1 is provided with an operating mechanism, or both the inlet end and the discharge end of the stacking frame 1 are provided with operating mechanisms. The destacking method includes the following steps:

[0113] P1. Drive the operating component 33 along the feeding direction, the preset direction and / or the vertical direction using the driving component 32 until the operating component 33 moves to the bottom of the drill bit 100 to be moved in the enclosure space 11, so that the support component 333 can support the drill bit 100 to be moved.

[0114] P2. The operating components 33 of the two operating vehicles 3 move simultaneously along the material conveying direction, the preset direction and / or the vertical direction. The two operating components 33 drive the drill 100 to move simultaneously until the drill 100 is taken out from the enclosure space 11.

[0115] Furthermore, after the support member 333 supports the drill string 100 and removes it from the containment space 11, it drives the support member 333 to continue moving so as to support the drill string 100 to the second buffer platform 42 for subsequent use.

[0116] P3. Adjust the height of the stacking rack 1 to avoid the stacking rack 1 affecting the operation component 33 in the enclosure space 11 to unstack the drilling tool 100.

[0117] Specifically, the support 333 is driven to move so that it clamps the topmost enclosure 131 on the stacking platform 12; then, the support 333 is driven to move the clamped enclosure 131 away from the stacking frame 1, thereby reducing the height of the stacking frame 1 to accommodate the continuous reduction of the drill bit 100 in the enclosure space 11 during destacking.

[0118] P4. Repeat steps S1 to S3 until all drill bits 100 to be unpacked are removed from the containment space 11.

[0119] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
