Description

Technical Field

[0001] This utility model relates to the field of mining machinery technology, specifically to a shock-absorbing support device for a high-stability emulsion drilling rig. Background Technology

[0002] Coal mines present hazardous environments with flammable, explosive, and high-gas content, placing extremely high demands on the explosion-proof performance of drilling equipment. Traditional electric drilling rigs pose a risk of explosion due to electrical sparks, while emulsion drilling rigs, powered by emulsion, require no electricity, effectively avoiding explosions caused by electrical sparks and improving operational safety. Emulsion drilling rigs are not only suitable for coal mines but can also be widely used in metal mines, non-coal mines, and tunnel engineering. For example, emulsion drilling rigs perform exceptionally well in operations such as mixing and installing resin anchor bolts in rock tunnels and drilling anchor bolt holes in tunnel walls.

[0003] Chinese Patent CN211524719U provides a vibration damping device for an emulsion drilling rig, comprising an emulsion drilling rig body, a vibration damping mechanism, and a lifting mechanism. The emulsion drilling rig body includes an operating platform, a support A, a rotating shaft, a drill rod, and a support base. The vibration damping mechanism includes a vibration damping cylinder B. The bottom end of the support A passes through the vibration damping cylinder B. A limiting ring A is fixedly connected to the bottom end of the support A. A limiting groove is formed at the bottom end of the limiting ring A. A spring A is fixedly connected to the bottom end of the limiting ring A. The bottom end of the spring A is fixedly connected to the inner bottom end of the vibration damping cylinder B. A base is fixedly connected to the bottom end of the vibration damping cylinder B. By installing spring A inside the vibration damping cylinder B, the vibration generated by the operation of the emulsion drilling rig body is transmitted to spring A through the support A. Under the elastic action of spring A, spring A can absorb the vibration generated by the operation of the emulsion drilling rig body, effectively improving the vibration resistance performance of the emulsion drilling rig body and extending the service life of the emulsion drilling rig body.

[0004] When using the emulsion drilling rig vibration damping device in the relevant technology, unidirectional vibration damping can only absorb vibration in a specific direction, which means that vibrations generated in other directions of the emulsion drilling rig cannot be effectively suppressed, thereby affecting the overall stability and service life of the drilling rig and increasing the failure frequency. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a vibration damping support device for a high-stability emulsion drilling rig. It solves the technical problem that in the related technology, when the vibration damping device for emulsion drilling rig is in use, unidirectional vibration damping can only absorb vibration in a specific direction, which means that vibration generated in other directions of the emulsion drilling rig cannot be effectively suppressed, thus affecting the overall stability and service life of the drilling rig, thereby improving the failure efficiency.

[0006] According to one aspect, at least one embodiment of the present invention provides a shock-absorbing support device for a high-stability emulsion drilling rig, comprising: a base, an auxiliary shock-absorbing component fixed to the outer side of the base, a support rod slidably connected to the top of the base, and an adjustment component fixed to the side of the support rod;

[0007] The auxiliary shock absorption assembly includes a buffer seat, the inner wall of which has a sliding groove, a sliding rod fixed in the sliding groove, a sliding block slidably connected to the sliding rod, a first damper fixed to the side of the sliding block, and a transverse shock absorption spring sleeved on the first damper.

[0008] For example, in a high-stability emulsion drilling rig vibration damping support device provided in at least one embodiment of the present invention, a longitudinal damping spring is fixed on the side of the base away from the sliding groove, and both the transverse damping spring and the longitudinal damping spring are sleeved on the first damper.

[0009] For example, in at least one embodiment of the present invention, a shock-absorbing support device for a high-stability emulsion drilling rig further includes: an extension column fixed to the top of the base, a limit ring fixed to the inner wall of the extension column, a second damper slidably connected in the limit ring, a vertical spring sleeved on the second damper, a shock-absorbing column fixed to the top of the vertical spring, a fixing block fixed to the bottom of the extension column, an inclined block slidably connected in the fixing block, and a dispersion spring fixed to the other end of the inclined block.

[0010] For example, in at least one embodiment of the present invention, a shock-absorbing support device for a high-stability emulsion drilling rig further includes: a protrusion fixed to the bottom of the vertical spring, the protrusion being matched with the inclined block.

[0011] For example, in at least one embodiment of the present invention, a shock-absorbing support device for a high-stability emulsion drilling rig further includes: a shock-absorbing column slidably connected to the bottom of the support rod, and a second damper installed at the bottom of the shock-absorbing column.

[0012] For example, in at least one embodiment of the present invention, a shock-absorbing support device for a high-stability emulsion drilling rig is provided, which further includes: the adjustment component includes a support block, a knob is rotatably connected to the side of the support block, a screw is fixed to the other end of the knob, a slider is threadedly connected to the screw, a connecting rod is hinged to the top of the slider, and a lifting column is hinged to the other end of the connecting rod.

[0013] For example, in at least one embodiment of the present invention, a shock-absorbing support device for a high-stability emulsion drilling rig further includes: the lifting column is fixed to the bottom of the support rod, the lifting column is slidably connected inside the shock-absorbing column, and a plurality of limit holes are opened on the side of the lifting column, with limit rods inserted into the limit holes.

[0014] For example, in at least one embodiment of the present invention, a shock-absorbing support device for a high-stability emulsion drilling rig is provided, which further includes a connecting groove on the side of the shock-absorbing column near the connecting rod.

[0015] The beneficial effects of the embodiments of this utility model are as follows:

[0016] In this invention, by setting up auxiliary vibration damping components, the vertical and horizontal vibration forces can be damped and buffered separately when the emulsion drilling rig is working, so that the emulsion drilling rig is more stable during use, thereby avoiding the situation where the stability of the drilling rig decreases due to poor vibration damping effect. At the same time, by setting up a dispersion device, the vertical vibration force can be dispersed in all directions, so that the vibration damping force of the vertical spring and the dispersion spring are the same, thereby reducing the vibration force distribution on the vertical spring and improving the service life of the vibration damping spring.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0025] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0026] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0028] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] like Figures 1-3 As shown, it illustrates a shock-absorbing support device for a high-stability emulsion drilling rig in one embodiment of the present invention, including a base 1, an auxiliary shock-absorbing component 2 fixed on the outside of the base 1, a support rod 4 slidably connected to the top of the base 1, and an adjustment component 3 fixed on the side of the support rod 4.

[0031] The auxiliary damping component 2 includes a buffer seat 21. A sliding groove 22 is provided on the inner wall of the buffer seat 21. A slide rod 23 is fixed in the sliding groove 22. A sliding block 24 is slidably connected to the slide rod 23. A first damper 215 is fixed on the side of the slide block 24. A transverse damping spring 25 is sleeved on the first damper 215. The first damper 215 and the transverse damping spring 25 are used together.

[0032] In some examples, a longitudinal damping spring 26 is fixed on the side of the base 1 away from the sliding groove 22. Both the transverse damping spring 25 and the longitudinal damping spring 26 are sleeved on the first damper 215. The longitudinal damping spring 26 is used to reduce the impact of vibration on the hydraulic drill when the vibration force of the hydraulic drill changes to the longitudinal direction, thereby making the operation of the hydraulic drill more stable. Several sets of the first damper 215 are provided, and transverse damping springs 25 and longitudinal damping springs 26 are respectively sleeved on the several sets of first dampers 215, so that the transverse damping springs 25 and longitudinal damping springs 26 can play a damping effect.

[0033] In some examples, an extension post 27 is fixed to the top of the base 1, and a limit ring 29 is fixed to the inner wall of the extension post 27. A second damper 216 is slidably connected in the limit ring 29. A vertical spring 210 is sleeved on the second damper 216. A shock-absorbing post 28 is fixed to the top of the vertical spring 210. A fixing block 212 is fixed to the bottom of the extension post 27. An inclined block 213 is slidably connected in the fixing block 212. A dispersion spring 214 is fixed to the other end of the inclined block 213. Both the dispersion spring 214 and the vertical spring 210 are sleeved on the second damper 216, so that the dispersion spring 214 and the vertical spring 210 can have a shock-absorbing effect. The dispersion spring 214 evenly distributes the vibration force received by the vertical spring 210 to other dispersion springs 214, thereby reducing the vibration force on the vertical spring 210 while allowing more vibration force to be released through the dispersion spring 214, thus increasing the vibration resistance of the vertical spring 210. To extend the service life of the dispersion spring 214 and facilitate long-term use, the limiting ring 29 can limit the vertical spring 210 to prevent it from shifting when subjected to vibration.

[0034] In some examples, a protrusion 211 is fixed to the bottom of the vertical spring 210. The protrusion 211 matches the inclined block 213. When the protrusion 211 contacts the inclined block 213, the protrusion 211 will push the inclined block 213 to the side, thereby causing the dispersion spring 214 on the other side of the inclined block 213 to contract and disperse the vibration force.

[0035] In some examples, a damping column 28 is slidably connected to the bottom of the support rod 4, and a second damper 216 is installed at the bottom of the damping column 28, so that when the support rod 4 is subjected to vertical vibration force, the damping column 28 slides in the extension column 27, thereby buffering part of the vibration force, and the second damper 216 and the vertical spring 210 are used for damping and diffusion.

[0036] For example, such as Figure 2As shown, when the hydraulic drill at the top of the support rod 4 is subjected to vibration, when the support rod 4 is subjected to lateral vibration, the base 1 moves towards both sides of the buffer seat 21 through the contraction of the lateral damping spring 25 on the first damper 215. This allows the lateral vibration to be damped by the cooperation of the first damper 215 and the lateral damping spring 25, preventing the hydraulic drill from being affected by lateral vibration during operation. Furthermore, when the base 1 moves, it slides on the slide rod 23 via the sliding block 24 on the other side of the base 1, further enhancing the damping effect of the lateral damping spring 25 on the first damper 215. The same applies when the support rod 4 is subjected to longitudinal vibration. When the base 1 is subjected to vertical vibration, the vibration is absorbed by the lateral damping spring 25 on the first damper 215. The support rod 4 transmits the vibration force to the vertical spring 210 fitted on the second damper 216 at the bottom of the shock absorber 28, allowing the shock absorber 28 to slide within the limiting ring 29 on the inner wall of the extension column 27. When the protrusion 211 at the bottom of the vertical spring 210 contacts the inclined block 213 in the fixing block 212 at the bottom of the extension column 27 during the damping process, part of the vibration force in the vertical spring 210 is transmitted to the dispersion spring 214 through the protrusion 211 and the inclined block 213. As a result, the dispersion spring 214 contracts on the second damper 216 due to the compression between the protrusion 211 and the inclined block 213, thereby dispersing the vertical vibration force on the vertical spring 210 and then performing damping treatment, thus improving the service life of the vertical spring 210.

[0037] like Figures 4-5 As shown, this invention illustrates a shock-absorbing support device for a high-stability emulsion drilling rig in another embodiment. The adjusting component 3 includes a support block 31, a knob 32 rotatably connected to the side of the support block 31, a screw 33 fixed to the other end of the knob 32, a slider 34 threadedly connected to the screw 33, a connecting rod 35 hinged to the top of the slider 34, and a lifting column 36 hinged to the other end of the connecting rod 35. When the slider 34 moves threadedly on the screw 33, the connecting rod 35 is hinged, causing the lifting column 36 to be pushed, thereby moving up and down in the shock-absorbing column 28.

[0038] In some examples, the lifting column 36 is fixed to the bottom of the support rod 4 and slidably connected inside the shock-absorbing column 28. Several sets of limiting holes 37 are opened on the side of the lifting column 36, and limiting rods 38 are inserted into the limiting holes 37. The limiting holes 37 and the limiting rods 38 match, so that the limiting rods 38 can limit and fix the lifting column 36, allowing the support rod 4 to be adjusted to different heights.

[0039] In some examples, the shock-absorbing column 28 has a connecting groove 39 on the side near the connecting rod 35. The connecting groove 39 allows the connecting rod 35 to change from a parallel state to an inclined state when it rotates on the lifting column 36 and the slider 34 hinged on both sides, thereby allowing the lifting column 36 to be adjusted in height.

[0040] For example, such as Figure 3 As shown, firstly, according to the actual usage environment and conditions, the knob 32 is manually rotated, causing the screw 33 to rotate, thereby causing the slider 34 to move within the screw 33. During the movement of the slider 34, the connecting rod 35 hinged to the top of the slider 34 generates a pushing force on the lifting column 36, causing the lifting column 36 to rotate inside the connecting groove 39 when it is adjusted upward in the shock-absorbing column 28. When the lifting column 36 moves to the appropriate height, the limiting rod 38 is pressed into the limiting hole 37, causing the limiting rod 38 to pass through the shock-absorbing column 28 and be locked in the limiting hole 37, thus fixing the lifting column 36 and the shock-absorbing column 28. This ensures that the height of the support rod 4 is adjusted to match the actual usage environment and conditions, thereby reducing the vibration force generated during operation.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
