Description

Technical Field

[0001] This utility model belongs to the technical field of automated sorting equipment for petroleum geological exploration drilling tools, specifically relating to an automatic leveling mechanism for drilling tools. Background Technology

[0002] At drilling sites or pipe fitting factories, the sorting and arrangement of scattered drill strings currently relies mainly on pipe-holding machines, cranes, and manual labor. This method suffers from high labor intensity, low efficiency, and a high risk of errors, and also poses safety hazards. With the development of automation technology, some intelligent sorting equipment incorporates tilt sensors and displacement sensors to detect the status of drill strings and achieves leveling by dynamically adjusting thrust or guide position. However, such solutions are costly, structurally complex, and lack reliability and practicality. Existing devices cannot achieve fully automated leveling of stacked drill strings. Utility Model Content

[0003] The present invention provides an automatic drilling tool leveling mechanism, which aims to overcome the problems of existing scattered drilling tool sorting and arranging devices, which are costly, complex in structure, and lack reliability and practicality; and manual sorting, which is labor-intensive, inefficient, and prone to errors.

[0004] Therefore, this utility model provides an automatic leveling mechanism for drill bits, including a leveling device, a conveyor belt, a frame, and a motor. The leveling device is connected to the upper part of the frame, and the conveyor belt and the motor are connected to the lower part of the frame. The leveling device is located above the conveyor belt, and the power output end of the motor is connected to the conveyor belt.

[0005] Preferably, the leveling device includes a leveling bar and a main frame, with the left and right ends of the main frame connected to the frame, and the leveling bar connected to the bottom of the main frame.

[0006] Preferably, the conveyor belt includes multiple drill bit support blocks, sprockets, roller chains, and a support base. A frame is connected to the support base, and a set of sprockets is connected to both the left and right ends of the support base. Multiple drill bit support blocks are connected to the outside of the two sets of sprockets through roller chains. The multiple drill bit support blocks are distributed at intervals outside the roller chains along the movement of the roller chains. The sprockets are connected to the power output end of the motor.

[0007] Preferably, both the flat stop bar and the drill bit support block are arranged longitudinally in the front and rear directions.

[0008] Preferably, the plurality of drill bit support blocks and roller chains are fixedly connected.

[0009] Preferably, the drill bit support block is a V-shaped support block with the tip of the V-shaped support block facing outward.

[0010] Preferably, the roller chain is a double-row roller chain.

[0011] Preferably, the support base includes two sets of support components, which are symmetrically arranged front and rear. The drill bit support block, sprocket, and roller chain are all located between the two sets of support components. The support components include a first support plate, multiple base support blocks, and a second support plate. Both the first and second support plates are arranged vertically from left to right. Each end of the first support plate is connected to a set of sprockets. Multiple base support blocks are connected to the first support plate between the two sets of sprockets. The multiple base support blocks are spaced apart from left to right. The second support plate is connected below the multiple base support blocks.

[0012] Preferably, support plate one is located inside support plate two.

[0013] Preferably, the main frame includes a horizontal frame and a vertical frame, with the vertical frame connected to the bottom of the horizontal frame and a flat stop bar connected to the bottom of the vertical frame.

[0014] The beneficial effects of this utility model are: This utility model provides an automatic drill bit leveling mechanism. The drill bit is placed on a conveyor belt, which is driven by a motor. The conveyor belt lifts the drill bit and moves it horizontally to a leveling device. The height difference between the leveling device and the conveyor belt is slightly greater than the diameter of the drill bit. When stacked drill bits pass through, the leveling device blocks the upper layer of drill bits and pushes them backward, causing the drill bits to fall sequentially onto the conveyor belt, achieving an orderly arrangement of individual drill bits. No manual assistance is required, improving drill bit sorting efficiency and reducing operational safety hazards. This automatic drill bit leveling mechanism adopts a purely mechanical structure, resulting in low cost, simple method, high reliability, and strong practicality. Attached Figure Description

Base support block. Detailed Implementation

[0018] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0019] Example 1: like Figure 1 As shown, an automatic leveling mechanism for drill bits includes a leveling device 1, a conveyor belt 2, a frame 4, and a motor. The leveling device 1 is connected to the upper part of the frame 4, and the conveyor belt 2 and the motor are connected to the lower part of the frame 4. The leveling device 1 is located above the conveyor belt 2, and the power output end of the motor is connected to the conveyor belt 2.

[0020] Specifically, the drill bit is placed on the conveyor belt 2, which is driven by a motor to move. The conveyor belt 2 lifts the drill bit and moves it horizontally to the leveling device 1. The height difference between the leveling device 1 and the conveyor belt 2 is slightly greater than the diameter of the drill bit. When stacked drill bits pass by, the leveling device 1 blocks the upper layer of drill bits and pushes them backward, causing the drill bits to fall onto the conveyor belt 2 in sequence, achieving an orderly arrangement of individual drill bits without manual assistance. This improves the efficiency of drill bit sorting and reduces operational safety hazards. The automatic drill bit leveling mechanism of this utility model adopts a purely mechanical structure, which is low in cost, simple in method, highly reliable, and highly practical.

[0021] Example 2: Based on Embodiment 1, the leveling device 1 includes a leveling bar 11 and a main frame 12. The left and right ends of the main frame 12 are connected to the frame 4, and the leveling bar 11 is connected to the bottom of the main frame 12.

[0022] Specifically, the main frame 12 is fixedly connected to the frame 4 to position the flat stop bar 11, preventing the flat stop bar 11 from moving when blocking the drill bit, thus ensuring the reliable stability of the structure.

[0023] Preferably, the main frame 12 includes a horizontal frame 12.1 and a vertical frame 12.2, with the vertical frame 12.2 connected to the bottom of the horizontal frame 12.1, and a flat stop bar 11 connected to the bottom of the vertical frame 12.2.

[0024] Specifically, the horizontal frame 12.1 facilitates the fixed connection between the frame 4 and the vertical frame 12.2, and the vertical frame 12.2 facilitates the connection between the flat stop bar 11. The structure is simple and has good stability.

[0025] Preferably, the main frame 12 is an integrated structure.

[0026] Specifically, the integrated structure has fewer connecting parts and better stability.

[0027] Preferably, the vertical frame 12.2 includes two vertical plates 12.21, the upper ends of the two vertical plates 12.21 are symmetrically connected to the horizontal frame 12.1, and the lower ends of the two vertical plates 12.21 are connected to a flat stop bar 11.

[0028] Specifically, the structure is simple and lightweight, ensuring the stability of the flat stop bar 11 connection.

[0029] Example 3: Based on Example 2, such as Figure 2 As shown, the conveyor belt 2 includes multiple drill bit support blocks 21, sprockets 22, roller chains 23, and support bases 24. The support base 24 is connected to a frame 4. Each of the left and right ends of the support base 24 is connected to a set of sprockets 22. The outside of the two sets of sprockets 22 is connected to multiple drill bit support blocks 21 through roller chains 23. The multiple drill bit support blocks 21 are spaced apart outside the roller chains 23 along the moving direction of the roller chains 23. The sprockets 22 are connected to the power output end of the motor.

[0030] Specifically, the conveyor belt 2 is driven by a motor to rotate the sprocket 22. The sprocket 22 drives the roller chain 23 and multiple drill support blocks 21 to rotate radially. The multiple drill support blocks 21 lift the drills and move them to the leveling device 1. When the stacked drills pass by, the leveling stop bar 11 blocks the upper drills and pushes them backward, so that the drills fall into the grooves between two adjacent drill support blocks 21 in sequence, achieving an orderly arrangement of single drills. This structure is a purely mechanical structure with low cost, simple method, high reliability, and strong practicality. It improves the efficiency of drill sorting and reduces operational safety hazards.

[0031] Preferably, both the flat stop bar 11 and the drill bit support block 21 are arranged longitudinally in the front and rear directions.

[0032] Specifically, the planar stop 11 and the drill bit support block 21 are ensured to fully contact the outer side of the drill bit along its axial direction, so that the drill bit is stably engaged in the groove between two adjacent drill bit support blocks 21, allowing the drill bit to move smoothly with the drill bit support block 21. When the planar stop 11 pushes the drill bit, the contact surface between the planar stop 11 and the drill bit is increased, ensuring that the planar stop 11 smoothly pushes the drill bit into the groove between two adjacent drill bit support blocks 21.

[0033] Preferably, the plurality of drill bit support blocks 21 and roller chains 23 are fixedly connected.

[0034] Specifically, this ensures that multiple drill bit support blocks 21 move stably with the roller chain 23.

[0035] Preferably, the drill bit support block 21 is a V-shaped support block with the tip of the V-shaped support block facing outward.

[0036] Specifically, a V-groove is formed between two adjacent drill bit support blocks 21. The V-shaped structure of the support block has an automatic centering characteristic, and it can automatically be located at the center of the V-groove regardless of how the drill bit diameter changes within a certain range. The V-shaped support block has a large contact area with the drill bit, which can provide support from both sides and effectively suppress the lateral vibration of the drill bit. The V-shaped structure has a certain compatibility with the drill bit diameter and can adapt to drill bits of various diameters. It can meet the support requirements of different specifications of drill bits without frequent replacement of the drill bit support blocks 21, thereby improving the versatility and practicality of the equipment and reducing production costs. The drill bit can be easily placed or pushed out between the V-shaped support blocks. During the lowering or lifting of the drill bit, the V-shaped support blocks can play a guiding role, guiding the drill bit to move along the correct path and preventing the drill bit from deviating from the predetermined position, thereby improving the safety and reliability of the operation process.

[0037] Preferably, the roller chain 23 is a double-row roller chain.

[0038] Specifically, compared to single-row roller chains, double-row roller chains distribute the load effectively by having two sets of chains bear the force simultaneously. Compared to single-row roller chains of the same specifications, double-row roller chains have stronger load-bearing capacity, higher power transmission, higher transmission stability, more compact structure, and higher space utilization.

[0039] Preferably, the support base 24 includes two sets of support components, which are symmetrically arranged front and rear. The drill bit support block 21, sprocket 22, and roller chain 23 are all located between the two sets of support components. The support components include a first support plate 24.1, multiple base support blocks 24.3, and a second support plate 24.2. The first support plate 24.1 and the second support plate 24.2 are both arranged vertically from left to right. Each end of the first support plate 24.1 is connected to a set of sprockets 22. Multiple base support blocks 24.3 are connected to the first support plate 24.1 between the two sets of sprockets 22. The multiple base support blocks 24.3 are distributed at intervals from left to right. The second support plate 24.2 is connected to the lower part of the multiple base support blocks 24.3.

[0040] Specifically, two sets of support components limit and connect the drill bit support block 21, sprocket 22, and roller chain 23, resulting in a simple structure.

[0041] Preferably, support plate 1 24.1 is located inside support plate 2 24.2.

[0042] Specifically, support plate 24.2 acts as a longitudinal limit for support plate 24.1.

[0043] Preferably, the plurality of base support blocks 24.3 are snapped onto the support plate 24.2.

[0044] Specifically, the structure is easy to install and disassemble.

[0045] Preferably, the tip of the drill bit support block 21 is connected to a plurality of connecting pieces 21.1, which are longitudinally spaced apart.

[0046] Specifically, during the lowering of the drill string, multiple connecting plates 21.1 share the load, which reduces the wear rate of individual connecting plate 21.1 surfaces. Even if some connecting plates 21.1 show slight wear due to long-term use, other connecting plates 21.1 that are not severely worn can still continue to play a supporting role, delaying the scrapping cycle of the entire support block and reducing maintenance costs and spare parts consumption.

[0047] Preferably, the connecting piece 21.1 is a V-shaped connecting piece.

[0048] Specifically, the V-shaped connecting piece ensures a full fit with the V-shaped support block.

[0049] Preferably, the height difference between the leveling bar 11 and the conveyor belt 2 is less than the minimum diameter of the drill bit.

[0050] Specifically, this structure ensures that the flat stop 11 can effectively push the drill bit.

[0051] Preferably, the motor is a servo motor.

[0052] Specifically, servo motors improve control precision.

[0053] The working principle of the automatic drilling tool leveling mechanism of this utility model is as follows: When the motor starts, it drives the sprocket 22 to rotate. The sprocket 22 drives the roller chain 23 and multiple drill support blocks 21 to rotate radially. The scattered drills 3 fall into the conveyor belt 2, with most of their volume embedded in the groove between two adjacent drill support blocks 21. They move together with the drill support blocks 21 to the leveling device 1. When stacked drills pass through, the height difference between the leveling stop bar 111 and the drill support block 21 only allows a single drill to pass through. If the drills are stacked, the leveling stop bar 111 will block the upper drill 3 and push it backward until all the drills 3 fall into the groove, achieving an orderly arrangement.

[0054] The pneumatic control components (such as solenoid valves and pressure reducing units) can adjust the motor speed to ensure smooth transmission of drill string 3. This automatic drill string leveling mechanism can be linked with the drill string detection and transmission system to achieve fully automated drill string sorting, improving oilfield operation efficiency and safety.

Therefore, the terms used to describe positional relationships in the drawings are for illustrative purposes only and should not be construed as limiting this utility model.

[0056] The above examples are merely illustrative of this utility model and do not constitute a limitation on the scope of protection of this utility model. All designs that are the same as or similar to this utility model are within the scope of protection of this utility model.
