Abstract
Description
Technical Field
[0001] This utility model relates to the field of drill pipe storage technology, and specifically to a lifting device for drill pipe storage equipment. Background Technology
[0002] Drill pipe is an essential tool in the drilling process. Each drilling project requires a large quantity of drill pipe, and each drill pipe is quite heavy. To facilitate the storage and retrieval of drill pipe, the existing technology often uses a bracket-type drill pipe storage rack, in which the drill pipe is delivered to the retrieval position by gravity rolling or manual handling.
[0003] Existing drill pipe storage and supply devices mostly rely on manual pushing or simple inclined slides to roll the drill pipes sequentially to the front position. This often requires worker assistance for adjustments, resulting in high labor intensity, low efficiency, significant impact from the rolling drill pipes, and difficulty in precise positioning. Especially when used in conjunction with robotic arms or automated gripping devices, the drill pipes cannot be stably and accurately delivered to the gripping position, easily causing connection problems and affecting the level of automation in construction. Utility Model Content
[0004] The technical problem to be solved by this utility model is that the storage and supply of drill rods in drilling projects is labor-intensive and inefficient when done manually. The purpose is to provide a lifting device for drill rod storage equipment, which can lift the drill rods on the storage equipment and allow them to roll naturally to the grabbing device to complete the supply, thereby reducing manual operation.
[0005] This utility model is achieved through the following technical solution: A lifting device for a drill pipe storage device includes: A storage rack, the bottom of which is provided with a support frame, and a bracket is provided on one side of the support frame, and the drill rod is placed along the lateral direction of the storage rack; The first lifting group and the second lifting group are arranged opposite to each other on both sides of the bottom of the storage rack; The second lifting group is located below the bracket, and the output end of the second lifting group is connected to the bracket. The first lifting group is arranged opposite to the second lifting group, and the output end of the first lifting group is connected to the storage rack. The side of the storage rack near the second lifting group is rotatably connected to the support frame.
[0006] In the above technical solution, a batch of drill rods is placed on a storage rack, and through the cooperation of the first lifting group and the second lifting group, the storage rack and the bracket are raised, which drives the single drill rod to rise and complete the transportation, thereby improving work efficiency and reducing labor intensity.
[0007] Preferably, the support frame is provided with a bearing seat, and the bottom surface of the storage rack is provided with connecting blocks on both sides in the horizontal direction. A rotating shaft is connected to the middle of the two connecting blocks, and the rotating shaft is rotatably connected in the shaft hole of the bearing seat.
[0008] In the above technical solution, when the storage rack rises, it is kept tilted by the rotational cooperation of the rotating shaft and bearing seat, so that the drill rod rolls into the bracket.
[0009] Preferably, a fixed plate and a movable plate are symmetrically arranged on one side of the top surface of the support frame. The fixed plate and the movable plate are located on both sides of the bracket in the length direction. The movable plate can slide in the lateral direction of the support frame. The height of the fixed plate and the movable plate is equal to the height of the bracket.
[0010] In the above technical solution, the fixed plate and the movable plate are used to fix the drill rod after the bracket is raised, so as to prevent the drill rod from deviating from its position.
[0011] Preferably, the support frame has a shelf on both sides of its top surface. The shelf closer to the fixed plate is fixedly connected to the fixed plate, and a third lifting group is provided on the shelf closer to the movable plate. The output end of the third lifting group is connected to the movable plate.
[0012] In the above technical solution, the third lifting group is used to control the movement of the moving plate, and then clamps the drill rod together with the fixed plate.
[0013] Preferably, the storage rack includes a base frame and support rollers. The base frame is U-shaped, and side rails extend outward from both sides of the base frame in the lateral direction. The support rollers are disposed on the top surface of the base frame.
[0014] In the above technical solution, the drill rod placed on the storage rack will fall onto the support roller for easy rolling, and the side rail can prevent the drill rod from falling.
[0015] Preferably, the top of the bracket is provided with a receiving groove, and the minimum moving height of the bracket is the same as that of the support roller.
[0016] In the above technical solution, the receiving groove is used to hold and restrict the drill rod to prevent it from falling off.
[0017] Preferably, the side of the base frame closest to the first lifting group is away from the support frame, and the first lifting group, the second lifting group, and the third lifting group are all cylinders.

[0019] Preferably, the support frame has a partition on the side near the bracket, and the partition is curved toward the bracket in an arc shape.
[0020] In the above technical solution, the partition can isolate the drill rod that has not fallen into the bracket, preventing the drill rod that has not fallen into the bracket from directly hitting the bracket.
[0021] Preferably, the partition is located in the middle of two adjacent drill rods on the side of the storage rack near the bracket.
[0022] In the above technical solution, the partition is used to isolate the first drill rod and the second drill rod near the bracket side, preventing the second drill rod from hitting the bracket.
[0023] Preferably, the partition is slidably connected to the support frame, and when the first lifting group raises the storage rack to its maximum height, the partition is lower than the lowest height of the inclined plane formed by the storage rack.
[0024] In the above technical solution, after the storage rack is raised, the partition is located at the bottom of the storage rack and no longer obstructs the drill rod from falling, allowing the drill rod to roll onto the bracket.
[0025] Compared with the prior art, this utility model has the following advantages and beneficial effects: After all the drill rods of the same batch are placed on the storage rack, the first lifting group can be operated to control one side of the storage rack to rise. The storage rack is raised and tilted by cooperating with the rotating shaft. At the same time, the second lifting group is started. The second lifting group controls the bracket to slowly rise vertically. When the storage rack changes from horizontal to tilted, the first drill rod on the storage rack near the bracket rolls down onto the bracket by the action of the inclined plane. The bracket has a receiving groove to restrict and accommodate the rolling drill rod. Then, the drill rod on the bracket can be grabbed by the gripping device. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are for explaining the utility model only and are not intended to limit the utility model. It should be noted that this utility model is already in the actual research and development stage.
[0029] Example 1: like Figure 1 As shown, this embodiment 1 provides a lifting device for a drill pipe storage device, including: The storage rack has a support frame 2 at its bottom and a bracket 3 on one side of the support frame 2. The drill rod is placed along the horizontal direction of the storage rack. The first lifting group 41 and the second lifting group 42 are arranged opposite to each other on both sides of the bottom of the storage rack. The second lifting group 42 is located below the bracket 3, and the output end of the second lifting group 42 is connected to the bracket 3. The first lifting group 41 is set relative to the second lifting group 42. The output end of the first lifting group 41 is connected to the storage rack. The side of the storage rack near the second lifting group 42 is rotatably connected to the support frame 2.
[0030] like Figure 1 As shown, a bearing seat is provided on the support frame 2, and connecting blocks are provided on both sides of the bottom surface of the storage rack in the horizontal direction. A rotating shaft 13 is connected to the middle of the two connecting blocks, and the rotating shaft 13 is rotatably connected in the shaft hole of the bearing seat.
[0031] like Figure 1 As shown, the storage rack includes a base frame 11 and support rollers 12. The base frame 11 is U-shaped, and side rails are connected to both sides of the base frame 11 in the lateral direction. The support rollers 12 are set on the top surface of the base frame 11.
[0032] like Figure 1 As shown, the top of the bracket 3 is provided with a receiving groove, and the minimum moving height of the bracket 3 is the same as that of the support roller 12.
[0033] Specifically, the storage rack can be used to store or transport drill rods. After the drill rods are fed into the storage rack by the engineering equipment, they will be neatly arranged on the support rollers 12 of the storage rack. The side rails on both sides of the storage rack are used to prevent the drill rods from falling. The storage rack can be rotated by the rotating shaft 13 at the bottom and the bearing seat of the support frame 2, thereby changing the height of one side of the storage rack, so that the drill rods can achieve the effect of rolling and feeding.
[0034] Drill rod delivery principle: After all the drill rods in a batch are placed on the storage rack, the first lifting group 41 can be operated to control one side of the storage rack base 11 to rise. The storage rack is raised and tilted by cooperating with the rotating shaft 13. At the same time as the first lifting group 41 is started, the second lifting group 42 is also started simultaneously. The second lifting group 42 controls the bracket 3 to slowly rise vertically. When the storage rack changes from horizontal to tilted, the first drill rod on the side of the storage rack near the bracket 3 rolls down onto the bracket 3 by the action of the inclined plane. The bracket 3 is provided with a receiving groove to restrict and accommodate the rolling drill rod.
[0035] After the first drill rod rolls onto the bracket 3, the second drill rod should also roll down. However, the second lifting group 42 is also controlling the bracket 3 to rise. After the first drill rod falls onto the bracket 3, the bracket 3 is already rising. The second drill rod can only touch the side wall of the bracket 3 and remain on the storage rack, and cannot continue to roll down. After the second lifting group 42 drives the bracket 3 to rise to its maximum height, the first lifting group 41 controls the storage rack to fall back to its original position and remain horizontal. The first drill rod on the bracket 3 will be grabbed and delivered by the robotic arm that grabs the drill rod. After the delivery is completed, the second lifting group 42 is controlled to fall down, and the bracket 3 returns to its original position. In this way, the original second drill rod will become the first drill rod of the next process and fall into the bracket 3 to continue to complete the delivery. This cycle continues until the delivery of this batch of drill rods on the storage rack is completed.
[0036] Example 2: like Figure 1 As shown, a fixed plate 21 and a movable plate 22 are symmetrically arranged on one side of the top surface of the support frame 2. The fixed plate 21 and the movable plate 22 are located on both sides of the length direction of the bracket 3, respectively. The movable plate 22 can slide along the transverse direction of the support frame 2. The height of the fixed plate 21 and the movable plate 22 is equal to the height of the bracket 3.
[0037] like Figure 1 As shown, both sides of the top surface of the support frame 2 are provided with a shelf 23. The shelf 23 on the side closer to the fixed plate 21 is fixedly connected to the fixed plate 21. The shelf 23 on the side closer to the movable plate 22 is provided with a third lifting group 43. The output end of the third lifting group 43 is connected to the movable plate 22.
[0038] like Figure 1 As shown, the side of the base frame 11 closest to the first lifting group 41 is away from the support frame 2. The first lifting group 41, the second lifting group 42 and the third lifting group 43 are all cylinders.
[0039] Specifically, during the rod feeding process as in Example 1, after the first drill rod falls into the bracket 3, one end of the drill rod in the length direction is constrained by the fixed plate 21, while the other end is close to the moving plate 22 and is not constrained for the time being. Since the drill rod is heavy and long, there may be stability issues when the bracket 3 drives the drill rod to rise, which may cause the drill rod to deviate from the predetermined direction when it is subsequently grabbed.
[0040] In this embodiment, as the second lifting group 42 is activated, the third lifting group 43 can also be activated, driving the far-end moving plate 22 to move closer to the fixed plate 21, so that the moving plate 22 and the fixed plate 21 respectively clamp the two ends of the drill rod, improving stability and ensuring that the drill rod is always laid flat with the bracket 3 as the center, avoiding position deviation, which would cause the gripping position to deviate from the original predetermined position during subsequent gripping.
[0041] It should also be noted that the first lifting group 41, the second lifting group 42 and the third lifting group 43 in this invention are all preferably cylinders, and the support frame 2 has corresponding facilities that can provide a power source for the cylinders.
[0042] Example 3: like Figure 2 and Figure 3 As shown, a partition 5 is provided on the side of the support frame 2 near the bracket 3, and the partition 5 is curved toward the bracket 3 in an arc shape.
[0043] like Figure 2 and Figure 3 As shown, the partition 5 is located in the middle of two adjacent drill rods on the side of the storage rack near the bracket 3.
[0044] like Figure 2 and Figure 3 As shown, the partition 5 is slidably connected to the support frame 2. When the first lifting group 41 lifts the storage rack to its maximum height, the partition 5 is lower than the lowest height of the inclined plane formed by the storage rack.
[0045] Specifically, compared to embodiment 1, the support frame 2 in this embodiment is provided with a partition 5. The partition 5 is detachably connected to the support frame 2 and is located in the middle of the support frame 2. In addition, the position of the partition 5 can be slidably adjusted according to the drill rod of different specifications and sizes. The support frame 2 is provided with a sliding groove. The bottom of the partition 5 is fixedly connected with a corresponding slider that is slidably connected to the sliding groove. After moving to the corresponding distance, the position of the partition 5 can be fixed by bolts or other fasteners to complete the fixation.
[0046] Unlike the rod feeding principle in Embodiment 1, in this embodiment, after a batch of drill rods is fed onto the storage rack, they will concentrate on the side of the partition 5 away from the bracket 3. When the storage rack is controlled to rise to an inclined state, the position of the partition 5 remains unchanged, but the height of the surface where the corresponding support roller 12 is located is higher than that of the partition 5. The drill rods fall, and the first drill rod rolls into the bracket 3 as in Embodiment 1. Then, the second lifting group 42 and the third lifting group 43 are controlled to move, the bracket 3 rises, and at the same time, the first lifting group 41 is controlled to return to its original position, and the storage rack falls. The two drill rods will not roll down to the position of the first drill rod as in Example 1. Instead, during the descent of the storage rack, they will be blocked again by the exposed partition 5. That is, the second drill rod will hit the partition 5 instead of the bracket 3. This can prevent the bracket 3 from shaking due to the impact of the drill rod when it rises and extend the service life of the bracket 3. The partition 5 can preferably be a low-cost material with high wear resistance and high strength, and can be replaced after damage. Repeat the above steps until the delivery of this batch of drill rods is completed.
[0047] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
