[0002] In the field of exploration, the current drill rod warehouse piles all the drill rods together without layering, and the positions of the drill rods in and out of the warehouse are fixed. Therefore, during use, the problem often occurs that when the drill rods are out of the warehouse or in the warehouse, there is a high impact force, and the order of the drill rods in and out of the warehouse is disordered, which makes it easy for the grabbing mechanism to get stuck or the drill rods to deviate and cannot be grabbed. Summary of the invention

[0029] The specific implementation modes of the present invention are further described in detail below with reference to the accompanying drawings.

[0030] Reference Figures 1 to 7 As shown, the present invention provides a multi-layer drill pipe storage and retrieval device for use in the field of exploration, and the intelligent multi-layer drill pipe storage and retrieval device is composed of the following parts: a layered positioning device 1, a layered fixing device 2, a layered supporting device 3, a layered lifting device 4, a lifting cylinder 5 and a drill pipe 6. Among them, the layered supporting device is arranged in four layers, namely the first layer 31, the second layer 32, the third layer 33 and the fourth layer 34. The left end of each layer is provided with a waist-shaped hole 35, which is connected to the layered fixing device 2 through a positioning shaft 21, and the right end is provided with a semicircular hole 36 with an opening facing downward. With the help of the cooperation between the semicircular hole 36 and the positioning shaft 44, the semicircular hole 36 is placed on the positioning shaft 44, and the positioning shaft 44 is fixed on the inner frame 42 of the layered lifting device 4. The inner frame 42 is connected to the lifting cylinder 5. Through the control of the lifting cylinder 5, the right end of each layer of the supporting device can move up and down, while the left end allows the corresponding positioning shaft to rotate appropriately, thereby forming a Figure 1 and Figure 2 The outbound and inbound status are shown.

[0031] When in the out-of-warehouse state, the left side of the layered support device 3 is lower than the right side, and the drill rod 6 placed therein tends to roll downward under the action of gravity. The maximum inclination angle α is 30 degrees (relative to the horizontal plane), and the rolling direction is from B to A. In the in-warehouse state, the rolling trend is from A to B, and the maximum downward inclination angle β is -30 degrees (relative to the horizontal plane). The control of the two limit positions is controlled by the two limit positions of the lifting cylinder 5, namely the upper limit position 51 and the lower limit position 52 in the figure.

[0032] The layered positioning device 1 can accurately position each layer through the servo motor 11, and cooperate with the lifting cylinder 5 to complete the storage process. It consists of a servo motor 11, a blocking platform 12 (equivalent to a base), a mounting seat 13 (relative to a buffer seat) and a main body 14.

[0033] Its main function is that the servo motor 11 drives the blocking platform 12 to rise and fall, and is used to prevent the drill rods in the rod storage below the current storage layer from rolling out. The mounting seat 13 is an inclined surface (i.e., it has an inclined surface as a drill rod receiving surface), which can allow the drill rods to automatically pass through the storage. At the same time, the mounting seat is made of nylon, which can effectively alleviate the impact of the drill rods, avoid collision of the drill rods, and reduce the wear of the drill rods. A baffle 15 is also set on its side.

[0034] For the blocking positioning of the long rod, a layered positioning device 1 is installed on each side (see Figure 3 ), which can effectively make the drill rod more stable when entering or leaving the warehouse, and avoid the occurrence of the drill rod being cut obliquely or other situations that may cause the drill rod to get stuck when entering or leaving the warehouse. The blocking platform 12 has a zigzag rib plate 16, which can further increase its strength, stability and impact resistance.

[0035] The layer fixing device 2 is used to support the drill rod 6 and is connected to the layer supporting device 3. The layer supporting device 3 is used to support the drill rod to achieve layering. The layer lifting device 4 is an actuator for changing the in and out angle. The layer fixing device 2, the layer supporting device 3 and the layer lifting device 4 are used in conjunction with each other. Figure 7 shown.

[0036] That is, the outer frame 41 of the layered fixing device 2 and the layered lifting device 4 is fixed, and the two ends of the layered support device 3 are respectively connected to the layered fixing device 2 and the layered lifting device 4. Since the connection between the layered support device 3 and the layered fixing device 2 is a waist-shaped hole (refer to the number 35 in the figure), it can not only support and connect, but also prevent the inner frame 42 of the part layered lifting device from being over-positioned when moving up and down. The connection method of the semicircular hole 36 can not only connect and support, rotate, but also prevent it from moving, and is also convenient for disassembly and assembly. The outer frame 41 is fixed, and the inner frame 42 moves up and down in the outer frame, with a wear-resistant plate 43 between them, and a lubricant on the wear-resistant plate to reduce friction and facilitate movement. If necessary, an avoidance space can be set on the outer frame to facilitate the up and down displacement of the inner frame.

[0037] The lifting cylinder 5 used in conjunction provides power for the drill pipe to be put in and out of the warehouse. The lifting cylinder is adjusted by a synchronous valve. When it is out of sync after running for a period of time, it needs to be calibrated regularly. The calibration method is to manually open the synchronous valve, run the cylinder to the uppermost or lowermost end, and then close the synchronous valve to complete the calibration process.

[0038] Warehousing process: refer to Figure 2 and Figure 5 When the drill rod is put into storage, the lifting cylinder drops to the lower limit, and the drill rod rolls from position A to position B for storage. At the same time, the layered positioning device is used for storage, and the position is (P4-P3-P2-P1). The storage order is the first layer-the second layer-the third layer-the fourth layer. Use the grabbing mechanism to transport the drill rod to the specified position (P4, P3, P2, P1).

[0039] Outbound process: refer to Figure 1 and Figure 6 When the drill rod is out of the warehouse, the lifting cylinder rises to the upper limit, and the drill rod rolls from position B to position A for out of the warehouse. At the same time, it is put into the warehouse with the layered positioning device, and the position is (P8-P7-P6-P5). The outgoing order is the fourth floor-the third floor-the second floor-the first floor. When the drill rod arrives at (P8, P7, P6, P5), the grabbing mechanism transports it to the next process.

[0040] The number of layers of the storage layering device of the present invention can be set to 2-10 layers. The angle of the drill rod when entering and leaving the storage is preferably in the range of -30° to +30°. The driving form of the layered positioning device can be electric, pneumatic or hydraulic transmission. The lifting cylinder can be hydraulic, motor or pneumatic. The lifting cylinder of the present invention adopts synchronous control and is provided with a correction device.
