Description
Technical Field
[0001] This utility model relates to the field of emulsion drilling rig technology, specifically a speed reducer device for emulsion drilling rigs. Background Technology
[0002] Emulsion drilling rigs are drilling equipment that uses emulsion as a power source. They are widely used in mining, tunnel construction, geological exploration, and other fields, especially in environments with flammable and explosive risks such as underground coal mines. The reducer reduces the speed and increases the torque of the input motor or hydraulic motor, which in turn drives the connecting disc (or output shaft) of the drill rod connected to the reducer. The connecting disc (or output shaft) is connected to the drill rod or other output devices of the whole machine through pins or bolts to realize the working process of the drilling rig.
[0003] In existing technologies, the internal reducer of traditional equipment is inconvenient to replace. Maintenance is also hampered by its complex disassembly and assembly, requiring the removal of numerous related components, leading to significantly extended downtime and severely impacting construction progress. Furthermore, the confined operating space and highly integrated design increase maintenance difficulty, making it prone to secondary damage due to improper operation. It demands extremely high personnel skills, has poor emergency response capabilities, and cannot quickly replace components in case of sudden malfunctions, potentially paralyzing the drilling rig, delaying critical processes, and even posing safety hazards. In terms of cost, each replacement requires more manpower and hours, driving up labor costs; repeated disassembly also exacerbates wear and tear on surrounding components, increasing the probability of unplanned replacements; and the need to stockpile complete machines to cope with malfunctions increases inventory costs. Moreover, it is difficult to adapt to equipment upgrade needs, potentially requiring modification of the entire machine or replacement of equipment, further increasing costs. These disadvantages are particularly pronounced in scenarios with high requirements for continuity and safety, such as underground mines. Utility Model Content

[0010] In the preferred embodiment of this technical solution, the mounting connector has a groove at the corresponding position of the rotating cylinder, and the rotating cylinder rotates inside the groove.
[0011] Based on the preferred embodiment of this technical solution, the sliding extrusion block is provided with anti-slip texture, and the anti-slip texture on the sliding extrusion block is in contact with the reducer body.
[0012] According to the preferred embodiment of this technical solution, the drive assembly includes a drive motor fixedly connected to the mounting bracket, a rotating shaft fixedly connected to the output end of the drive motor, a rotating rod fixedly connected to the rotating shaft, a fixed connecting block fixedly connected to the rotating rod, a reduction assembly disposed inside the reducer body, and a drill bit mounting rod fixedly connected to the reduction assembly.

[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. By rotating the adjusting shaft, the rotating worm gear and worm wheel are linked, allowing the sliding extrusion block to move flexibly. This enables rapid fixing and disassembly of the reducer body without disassembling numerous related components, significantly simplifying the replacement process, shortening downtime, and reducing the impact on construction progress. In terms of maintenance, the ease of assembly and disassembly reduces reliance on confined operating spaces, minimizing the risk of secondary damage due to improper operation. It also lowers the skill requirements for personnel, enhances emergency response capabilities, and allows for rapid replacement in case of sudden malfunctions, preventing drilling rig shutdowns. Regarding costs, it reduces manpower and labor hours, lowers labor costs, reduces wear and tear on surrounding components from repeated disassembly, and reduces the probability of unplanned replacements. Furthermore, the flexible fixing method facilitates adaptation to equipment upgrade needs without requiring modification or replacement of the entire machine, further reducing costs, making it particularly suitable for scenarios such as underground mining.
[0016] 2. The first and second mounting shells are tightly connected by fixing bolts, forming a double protective barrier. This effectively isolates the reducer body and internal drive components from dust, water vapor, and gravel impacts in harsh environments such as underground mines, significantly reducing the probability of contamination or damage and extending the service life of the components. The limiting support frame provides stable support for the mounting connection seat, and the sliding groove on the mounting connection seat guides and limits the rotation and sliding parts, ensuring that the components maintain precise meshing and movement trajectory even under high-frequency vibration. This reduces malfunctions caused by component misalignment, improves the reliability and stability of the device, and provides strong support for continuous construction. In addition, multiple evenly distributed threaded adjusting rods drive the sliding extrusion blocks to evenly clamp the reducer body, which not only enhances the fixing effect but also prevents the reducer body from deforming due to excessive local stress, effectively protecting the precision and performance of the core components.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-5 This utility model provides an embodiment including a first mounting shell 1, a second mounting shell 2 disposed on the first mounting shell 1, a fixing bolt 3 disposed between the first mounting shell 1 and the second mounting shell 2, a connecting base 4 fixedly connected to the bottom of the first mounting shell 1, a limiting support frame 5 fixedly connected inside the second mounting shell 2, a mounting connecting seat 6 fixedly connected inside the limiting support frame 5, a reducer body 7 disposed on the mounting connecting seat 6, a drive assembly disposed inside the mounting connecting seat 6, a rotating cylinder 801 rotatably connected inside the mounting connecting seat 6, a rotating worm gear 802 rotatably connected inside the mounting connecting seat 6, and a rotating adjusting shaft 803 fixedly connected to the rotating worm gear 802. A rotating worm gear 804 is fixedly connected to a rotating cylinder 801; a rotating threaded disc 805 is fixedly connected to the rotating worm gear 804; a threaded adjusting rod 806 is rotatably connected inside the mounting base 6; and a sliding pressing block 807 is slidably connected inside the mounting base 6. A rotating worm gear 802 is engaged with the rotating worm gear 804; the rotating threaded disc 805 is rotatably connected inside the mounting base 6; the threaded adjusting rod 806 is engaged with the rotating threaded disc 805; and the sliding pressing block 807 is engaged with the threaded adjusting rod 806. A rotating adjusting shaft 803 drives the rotating worm gear 802 to rotate, which in turn drives the rotating worm gear 804 and the rotating cylinder 801 to rotate, causing the rotating threaded disc 805 to rotate synchronously. The rotating threaded disc 805 drives several threaded adjusting rods 806 to rotate, which in turn drives the sliding pressing block 807 to move along the slide groove of the mounting base 6, thereby fixing the reducer body 7.
[0025] Please see Figure 2-4A further solution based on this embodiment is as follows: the mounting connector 6 has a groove at the corresponding position of the threaded adjusting rod 806, and the threaded adjusting rod 806 rotates inside the groove. By opening a groove on the mounting connector 6 at the position corresponding to the threaded adjusting rod 806, a stable rotation space is provided for the threaded adjusting rod 806, ensuring that the threaded adjusting rod 806 will not shift its position during rotation, and ensuring the accuracy and stability of the meshing transmission between the threaded adjusting rod 806 and the rotating threaded disc 805 and the sliding extrusion block 807.
[0026] Please see Figure 2-4 A further solution based on this embodiment is as follows: a plurality of threaded adjusting rods 806 are provided, and the plurality of threaded adjusting rods 806 are evenly rotatably connected inside the mounting connection seat 6. By providing a plurality of evenly distributed threaded adjusting rods 806, forces can be applied to the sliding extrusion block 807 from multiple directions, so that the extrusion and fixation of the sliding extrusion block 807 on the reducer body 7 is more uniform, and the reducer body 7 is prevented from tilting or displacing due to uneven force.
[0027] Please see Figure 2-4 A further solution based on this embodiment is as follows: the mounting connector 6 has a groove at the corresponding position of the sliding extrusion block 807, and the sliding extrusion block 807 rotates inside the groove. By opening the groove at the position of the sliding extrusion block 807 on the mounting connector 6, the movement trajectory of the sliding extrusion block 807 is effectively restricted and guided, ensuring that the sliding extrusion block 807 can move smoothly along the preset direction and accurately contact the reducer body 7 to apply extrusion force.
[0028] Please see Figure 2-4 A further solution based on this embodiment is as follows: the mounting connector 6 has a groove at the corresponding position of the rotating cylinder 801, and the rotating cylinder 801 rotates inside the groove. By opening a groove on the mounting connector 6 at the position corresponding to the rotating cylinder 801, a stable support and space for the rotation of the rotating cylinder 801 are provided, ensuring that the rotating cylinder 801 can rotate flexibly, thereby ensuring the rotation of the worm gear 804 connected to it.
[0029] Please see Figure 2-4 A further solution based on this embodiment is as follows: anti-slip texture is provided on the sliding extrusion block 807. The anti-slip texture on the sliding extrusion block 807 is in contact with the reducer body 7. By providing anti-slip texture on the sliding extrusion block 807, the friction between the sliding extrusion block 807 and the reducer body 7 is increased, which can effectively prevent relative sliding between the reducer body 7 and the sliding extrusion block 807 when the drilling rig vibrates during operation, and further enhance the fixing effect on the reducer body 7.
[0030] Please see Figure 5A further solution based on this embodiment is as follows: the drive assembly includes a drive motor 808 fixedly connected to the mounting connector 6, a rotating shaft 809 fixedly connected to the output end of the drive motor 808, a rotating rod 810 fixedly connected to the rotating shaft 809, a fixed connecting block 811 fixedly connected to the rotating rod 810, a reduction assembly 812 disposed inside the reducer body 7, and a drill bit mounting rod 813 fixedly connected to the reduction assembly 812. By setting the drive motor 808 as a power source, a stable driving force can be provided for the entire device; the sequential connection of the rotating shaft 809, the rotating rod 810 and the fixed connecting block 811 realizes the effective transmission of power.
[0031] Please see Figure 5 A further solution based on this embodiment is as follows: a slot is provided on the rotating column of the deceleration assembly 812 corresponding to the position of the fixed connecting block 811. The fixed connecting block 811 is engaged inside the slot of the rotating column. By providing a slot on the rotating column of the deceleration assembly 812 corresponding to the fixed connecting block 811, the fixed connecting block 811 can be firmly engaged in the slot, ensuring that the power transmitted by the drive motor 808 through the rotating shaft 809 and the rotating rod 810 can be stably and efficiently transmitted to the deceleration assembly 812.
[0032] Working principle: The rotating adjustment shaft 803 drives the rotating worm 802 to rotate. The rotating worm 802 meshes with the rotating worm wheel 804, thereby driving the rotating worm wheel 804 and the rotating cylinder 801 fixed thereto to rotate. The rotating cylinder 801 rotates flexibly in the corresponding slide groove of the mounting connecting seat 6, driving the rotating threaded disc 805 to rotate synchronously. The rotating threaded disc 805 meshes with several evenly distributed threaded adjusting rods 806. The threaded adjusting rods 806 rotate in the corresponding slide groove of the mounting connecting seat 6, thereby driving the sliding extrusion block 807 to move along the slide groove of the mounting connecting seat 6. The sliding extrusion block 807 contacts the reducer body 7 with its anti-slip texture, applying uniform extrusion force from multiple directions to achieve a stable fixation of the reducer body 7. During operation, the drive motor 808 on the mounting connector 6 provides power, which is transmitted to the rotating rod 810 via the rotating shaft 809 at the output end. The fixed connecting block 811 on the rotating rod 810 engages in the slot of the rotating column of the reduction assembly 812, stably transmitting power to the reduction assembly 812 inside the reducer body 7. After adjusting the input speed, the reduction assembly 812 outputs appropriate power through the drill bit mounting rod 813 to meet the drilling requirements. Throughout the process, the first mounting shell 1 and the second mounting shell 2 are combined with fixing bolts 3 to protect the internal components, the connecting base 4 ensures the overall stable installation of the device, and the limit support frame 5 provides stable support to the mounting connector 6, ensuring the coordinated operation of all components.
