Description

Technical Field

[0001] This utility model relates to the technical field of drilling rig carriages, and in particular to a carriage lifting device for drilling rigs. Background Technology

[0002] As a key piece of equipment in geological exploration and mineral resource development, the safety and ease of operation of the drilling rig's carriage lifting device are of paramount importance. In actual operation, the drilling rig needs to use the carriage lifting device to achieve precise positioning of the drill bit and drilling operations. However, existing drilling rig carriage lifting devices generally suffer from the following technical problems:

[0003] On the one hand, the drilling rig lacks a reliable safety triggering mechanism when starting. When the drilling rig descends to the drilling position via the slide, if it is accidentally started before the drill bit touches the ground, the high-speed rotating drill bit will lose support due to its suspended state, which can easily cause the drill rod to shake, the equipment to vibrate, or even become unbalanced. This not only affects the drilling accuracy but may also damage the drilling tools or injure the operators, posing a safety hazard.

[0004] On the other hand, the main body of existing drilling rigs typically adopts a fixed installation structure. When the drilling rig needs to be repaired or replaced, the entire carriage system must be disassembled, which is cumbersome, time-consuming, and labor-intensive. This makes it difficult to meet the needs of rapid equipment maintenance in industrial operations, resulting in extended downtime and reduced operational efficiency. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, this utility model proposes a slide lifting device for drilling rigs, which can automatically start and stop the drilling rig upon contact with the ground through a triggering structure to improve safety, and its detachable design facilitates maintenance and replacement.

[0007] To achieve the above objectives, this utility model proposes a sliding frame lifting device for a drilling rig, comprising a sliding rail with a sliding groove on its side, a servo motor mounted on its top, and a fixedly connected device base at its bottom; a lifting screw is fixedly connected to the output end of the servo motor, the lifting screw being threadedly connected to the inner wall of the lifting platform, the lifting platform being slidably connected to the sliding rail via the sliding groove, and having a threaded hole on its side; a contact switch is mounted on the side of the lifting platform and fixedly connected to a connecting block; a damping rod is fixedly connected between the connecting blocks, a drilling rig mounting plate is slidably connected to the outer wall of the damping rod, the drilling rig mounting plate is connected to a trigger spring via the connecting block, and an abutment plate is fixedly connected to its side.

[0008] The sliding frame lifting device for drilling rigs of this utility model can automatically start when the drilling rig contacts the ground and automatically shut down when it leaves the ground by sliding the drilling rig mounting plate on the damping rod, in conjunction with the abutment plate and the contact switch to form a trigger structure, thereby effectively improving safety. The detachable design of the drilling rig body and the mounting frame facilitates quick replacement and maintenance.

[0009] In addition, the carriage lifting device for drilling rigs proposed in this application may also have the following additional technical features:

[0010] Specifically, an auxiliary mounting bracket is fixedly connected to the side of the drilling rig mounting plate, and a fixing plate is fixedly connected to the side of the auxiliary mounting bracket.

[0011] Specifically, the inner wall of the auxiliary mounting bracket is slidably connected to the drilling rig body, and mounting blocks are fixedly connected to both sides of the drilling rig body.

[0012] Specifically, the mounting block has mounting holes and is slidably connected to a fixing screw via a fixing plate.

[0013] Specifically, a hexagonal nut is threaded onto the outer wall of the fixing screw, and the hexagonal nut abuts against the top of the fixing plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. Precise and reliable safe start control: Through the trigger structure design of the drilling rig mounting plate sliding along the damping rod, combined with the linkage mechanism of the contact plate and the contact switch, the drilling rig can be automatically started only when the drill bit touches the ground and immediately shut down when it leaves the ground. This completely avoids equipment shaking, drill bit damage and personnel safety hazards caused by starting the drill bit suspended in the air, and significantly improves the safety of operation.

[0016] 2. Convenient and efficient drilling rig maintenance: The drilling rig adopts a modular and detachable design for the main body and auxiliary mounting frame (through the cooperation of fixing screws, hexagonal nuts and fixing plates), which can quickly complete the disassembly and assembly of the main body of the drilling rig without disassembling the entire carriage system, greatly shortening maintenance time, reducing operation complexity, meeting the needs of rapid equipment maintenance in industrial operations, and improving operation efficiency.

[0017] 3. Strong structural linkage stability: The servo motor drives the lifting screw to move the lifting platform up and down along the sliding track. Combined with the limiting effect of the sliding groove, it ensures that the drilling rig is raised and lowered smoothly without deviation. The combination of the trigger spring and the damping rod can buffer the impact force when the drilling rig contacts the ground, reduce equipment vibration, and further ensure the stability and reliability of operation.

[0018] 4. High installation and adaptation flexibility: The main body of the drilling rig is fixed by a combination structure of mounting blocks, mounting holes and fixing plates, which can be adapted to different specifications of drilling rig models. By adjusting the connection position of the fixing screw and hexagonal nut, the main body of the drilling rig can be quickly positioned and fastened, enhancing the versatility and adaptability of the device.

[0026] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0027] The following description, in conjunction with the accompanying drawings, describes a slide lifting device for a drilling rig according to an embodiment of the present invention.

[0028] like Figures 1-4 As shown, the sliding frame lifting device for a drilling rig according to this embodiment of the present invention may include a sliding rail 1, a sliding groove 4 on the side of the sliding rail 1, a servo motor 2 installed on the top of the sliding rail 1, a device base 20 fixedly connected to the bottom of the sliding rail 1, a lifting screw 3 fixedly connected to the output end of the servo motor 2, the lifting screw 3 being threadedly connected to the inner wall of the lifting platform 5, the lifting platform 5 being slidably connected to the sliding rail 1 through the sliding groove 4, and having a threaded hole 19 on its side, a contact switch 9 installed on the side of the lifting platform 5, and a connecting block 11 fixedly connected thereto, a damping rod 17 fixedly connected between the connecting blocks 11, a drilling rig mounting plate 7 slidably connected to the outer wall of the damping rod 17, a trigger spring 18 connected to the drilling rig mounting plate 7 through the connecting blocks 11, and an abutment plate 10 fixedly connected to its side.

[0029] It should be noted that the contact switch 9 described in this embodiment adopts a normally closed design. When not triggered, the circuit is open, and when triggered (the contact plate 10 is pressed), the circuit is open, ensuring that the drilling rig only starts when in contact with the ground, thus avoiding accidental activation.

[0030] It should also be noted that a hydraulic or spring damping mechanism can be installed inside the damping rod 17 to slow down the sliding speed of the drilling rig mounting plate 7 and prevent the spring 18 from failing due to impact overload. Figure 4 The trigger spring 18 is sleeved on the outside of the damping rod 17.

[0031] Specifically, during the descent of the drilling rig, when the drill bit contacts the borehole surface, the drilling rig will be affected by pressure, causing the drilling rig mounting plate 7 to rise on the side of the lifting platform 5. Simultaneously, the drilling rig mounting plate 7 slides on the damping rod 17, and at the same time, the trigger spring 18 is compressed until the contact plate 10 rises and contacts the contact switch 9. This causes the contact switch 9 to start the drilling rig to perform drilling operations. During this process, the drilling rig will continue to descend, so there is no need to worry about the phenomenon of disconnection.

[0032] In one embodiment of this utility model, such as Figures 1-4 As shown, the auxiliary mounting bracket 8 is fixedly connected to the side of the drilling rig mounting plate 7, and the fixing plate 14 is fixedly connected to the side of the auxiliary mounting bracket 8.

[0033] Furthermore, the inner wall of the auxiliary mounting bracket 8 is slidably connected to the drilling rig body 6, and the mounting blocks 12 are fixedly connected to both sides of the drilling rig body 6.

[0034] Furthermore, the mounting block 12 has mounting holes 13 and is slidably connected to the fixing screw 16 via the fixing plate 14.

[0035] Furthermore, a hexagonal nut 15 is threaded onto the outer wall of the fixing screw 16, and the hexagonal nut 15 abuts against the top of the fixing plate 14.

[0036] Specifically, starting the servo motor 2 will cause the lifting screw 3 to rotate, so that the lifting platform 5 can drive the drilling rig body 6 to descend as a whole under the limit of the sliding rail 1. At the same time, when it is necessary to disassemble the drilling rig body 6, the hexagonal nut 15 and the fixing screw 16 can be removed, so that the disassembly of the drilling rig body 6 is no longer limited by the mounting block 12, thus facilitating the replacement and maintenance of the drilling rig body 6.

[0037] Specifically, the overall workflow and principle of this utility model are as follows:

[0038] When the servo motor 2 is not started, the lifting platform 5 is located at the top of the sliding rail 1, the drill body 6 is in a high position with the lifting platform 5, the drill bit is suspended in the air, the abutment plate 10 is separated from the contact switch 9, and the drill is in the closed state.

[0039] Start the servo motor 2, and its output drives the lifting screw 3 to rotate clockwise. Since the lifting screw 3 is threadedly connected to the threaded hole 19 of the lifting platform 5, and the lifting platform 5 is limited on the sliding rail 1 by the sliding groove 4, the lifting platform 5 descends vertically along the sliding rail 1, driving the drilling rig body 6 to move down synchronously.

[0040] When the drill bit contacts the ground, the ground reaction force pushes the drill body 6 and the drill mounting plate 7 to slide upward along the damping rod 17, and the trigger spring 18 is compressed.

[0041] The drilling rig mounting plate 7 moves up to the contact plate 10 and contacts the contact switch 9, the circuit is connected, the drilling rig starts automatically and begins drilling operations.

[0042] The damping rod 17 provides sliding guidance and damping buffer for the drilling rig mounting plate 7 to avoid excessive instantaneous impact force. The elastic force of the trigger spring 18 ensures that the contact plate 10 and the contact switch 9 continue to be in contact (so that the lifting platform 5 continues to descend) to prevent disconnection.

[0043] Servo motor 2 continuously drives the lifting platform 5 to descend, and the drill bit completes drilling under the drive of the drilling machine body 6. During this period, the contact plate 10 always maintains contact with the contact switch 9, and the drilling machine continues to run.

[0044] After the drilling reaches the predetermined depth, the servo motor 2 reverses, the lifting screw 3 rotates counterclockwise, the lifting platform 5 drives the main body of the drilling machine 6 to rise, and after the drill bit leaves the ground, the trigger spring 18 resets, pushing the drilling machine mounting plate 7 to move down along the damping rod 17, the abutment plate 10 separates from the contact switch 9, and the drilling machine automatically shuts down.

[0045] Finally, the lifting platform 5 returns to the top of the sliding rail 1, awaiting the next work instruction.

[0046] When disassembling and maintaining the main body of the drilling rig, unscrew the hexagonal nut 15, remove the fixing screw 16, release the fixed connection between the mounting block 12 and the fixing plate 14, and then slide the main body of the drilling rig 6 along the inner wall of the auxiliary mounting frame 8 to complete the individual disassembly, which is convenient for maintenance or replacement.

[0047] Align the mounting block 12 of the new drilling rig body 6 with the inner wall of the auxiliary mounting bracket 8, push it in until the mounting hole 13 is aligned with the screw hole of the fixing plate 14, insert the fixing screw 16 and tighten the hexagonal nut 15 to complete the quick installation.

[0048] In summary, the slide lifting device for drilling rigs in this embodiment of the present invention can automatically start when the drilling rig contacts the ground and automatically shut down when it leaves the ground by sliding the drilling rig mounting plate on the damping rod, in conjunction with the abutment plate and the contact switch to form a trigger structure, thereby effectively improving safety. Furthermore, the detachable design of the drilling rig body and the mounting frame facilitates quick replacement and maintenance.
