Description

TECHNICAL FIELD

[0001] The present application relates to the field of drilling technology, in particular to a drilling machine bed assembly. BACKGROUND

[0002] The drilling machine is a mechanical equipment that drives the drilling tool to drill into the ground to obtain physical geological data in the exploration or mineral resources development, also known as drilling machine, which can be used to drill core, rock, gaseous sample, liquid sample, etc. to explore the underground geology and mineral resources.

[0003] The drilling machine bed assembly in the prior art comprises a bed body, a drilling tool sliding on the bed body along the length direction of the bed body, and a driving mechanism (mostly hydraulic cylinder) driving the drilling tool to move. In order to ensure the stable movement of the drilling tool in a fixed direction, a slide rail is usually arranged on the bed body, and a sliding block in sliding cooperation with the slide rail and fixedly connected with the drilling tool is arranged in the slide rail. Through the guiding action of the sliding block and the slide rail, the stable movement of the drilling tool in a fixed direction is ensured.

[0004] However, during the use of the drilling machine, the sliding block not only has a guiding action but also bears the weight of the drilling tool, so the friction between the sliding block and the slide rail is large. When the sliding block slides on the slide rail, wear is easily generated between the sliding block and the slide rail, the service life of the sliding block and the slide rail is shortened, and the gap is easily generated due to the wear, which affects the accuracy of the moving direction of the drilling tool. With the increase of the use time, the gap gradually increases, and the sliding block is easily separated from the slide rail, thereby causing the drilling tool to be separated from the bed body. Not only is the drilling efficiency reduced, but serious accidents are also caused. The user needs to regularly and frequently replace the sliding block and the slide rail, which increases the drilling cost.

[0005] Therefore, it is necessary to improve the drilling machine bed assembly in the prior art. SUMMARY

[0006] The present application aims to overcome the defects in the prior art, and provide a drilling machine bed assembly which reduces wear, prolongs service life, reduces drilling cost, ensures drilling efficiency and accuracy of the moving direction of the drilling tool.

[0007] In order to achieve the above technical effects, the technical scheme of the present application is as follows: a drilling machine bed assembly, comprising a long strip-shaped rack, a moving seat slidingly arranged on the rack along the length direction of the rack, a driving mechanism driving the moving seat to slide, and a guide rail and a guide piece slidingly cooperating and arranged between the moving seat and the rack, wherein a load bearing assembly is further arranged on the moving seat, the load bearing assembly comprises a composite roller bearing, and the main roller and the side roller of the composite roller bearing roll on the rack along the length direction of the rack.

[0008] The mobile seat on the rack is used for connecting a drilling tool, drilling is performed through the drilling tool, the mobile seat is driven to move along the length direction of the rack by the driving mechanism, thereby adjusting the position of the drilling tool, the movement of the mobile seat is guided by the slidingly matched guide rail and guide piece, in order to reduce the abrasion between the guide rail and the guide piece, the composite roller bearing in the load bearing assembly is rolled on the rack, thereby achieving load bearing of the mobile seat, reducing the friction between the guide rail and the guide piece and the abrasion caused by the friction, thereby ensuring the accurate movement of the mobile seat, prolonging the service life, and reducing the replacement cycle of the guide rail and the guide seat.

[0009] Preferably, the rack is provided with a strip-shaped hole consistent with the length direction thereof, and the composite roller bearing is rolled on the inner side of the strip-shaped hole.

[0010] By adopting the above technical scheme, the composite roller bearing is rolled on the inner side of the strip-shaped hole, which is beneficial to make the drilling machine bed assembly structure more compact and avoid occupying too much space.

[0011] Preferably, the inner walls on both sides of the strip-shaped hole are fixed with convex strip assemblies extending along the length direction thereof, the composite roller bearing is provided with two groups and is arranged on the upper and lower sides of the convex strip assemblies, and the convex strip assemblies are clamped between the main rollers of the two groups of composite roller bearings.

[0012] By adopting the above technical scheme, the main rollers of the two groups of composite roller bearings clamp the convex strip assemblies, and the main rollers roll along the convex strip assemblies, thereby preventing the mobile seat from sliding up and down during movement, and thus ensuring the stability of the movement of the mobile seat.

[0013] Preferably, each group of composite roller bearings is provided with two composite roller bearings, and the side rollers of the two composite roller bearings are clamped between the two inner side walls in the length direction of the strip-shaped hole.

[0014] By adopting the above technical scheme, the two inner side walls of the strip-shaped hole are respectively abutted with the composite roller bearings in each group of composite roller bearings, so that the side rollers of the composite roller bearings can roll along the inner side walls, the accurate directional movement of the mobile seat is realized, the abrasion between the guide piece and the guide rail is reduced, the service life is prolonged, the drilling efficiency is ensured, and the increase of drilling cost caused by frequent replacement of the guide rail and the guide piece is avoided.

[0015] Preferably, the load bearing assembly is provided with at least two and is distributed at intervals along the length direction of the rack.

[0016] By adopting the above technical solution, the number of load-bearing components is increased, thereby increasing the load-bearing weight of the moving base and drill bit, reducing the friction between the moving base and the frame, and thus reducing the wear between the moving base and the frame during movement. This ensures that the moving base can move accurately in a fixed direction after the drive mechanism is started, reducing the amount of shaking during movement to ensure accurate drilling. At the same time, the reduced wear between the guide components and the guide rails extends the service life of the guide components and guide rails, reduces the replacement frequency, and thus reduces drilling costs.

[0017] Preferably, the guide rail is a guide groove that extends along the length of the frame and is located opposite to the two sides of the frame.

[0018] By adopting the above technical solution, the guide rails are arranged on both sides of the frame and back to back, which reduces the space occupied by the guide rails and makes the drilling rig bed assembly structure more compact.

[0019] Preferably, the frame is provided with a notch, and a wear-resistant plate is detachably provided on the inner wall of the notch. The guide groove is integrally formed on the side of the wear-resistant plate opposite to the inner wall of the notch.

[0020] By adopting the above technical solution, the wear-resistant plate is used to form a guide groove, so that when the moving seat moves along the length of the frame, the guide component slides on the wear-resistant plate, avoiding contact between the guide component and the frame and preventing the guide component from causing wear to the frame. When the equipment has been used for a long time, the wear-resistant plate can be replaced to ensure the precise sliding fit between the guide component and the guide groove, reduce the gap, and reduce the amount of shaking when the moving seat moves.

[0021] Preferably, the guide includes a slider disposed in the guide groove, and the slider is provided with a wear-resistant block that fits against the inner wall of the guide groove.

[0022] By adopting the above technical solution, the wear-resistant block is in close contact with the inner wall of the guide groove, which allows the slider to slide stably in the guide groove, preventing wear between the slider and the guide groove. This ensures that when the drive mechanism is running, the moving seat moves directionally along the length of the frame, reducing the amount of shaking.

[0023] Preferably, the wear-resistant block is detachably mounted on the slider.

[0024] By adopting the above technical solution, the wear-resistant block and the slider can be detachably connected. When the wear-resistant block is worn after long-term use, it is convenient to replace the wear-resistant block on the slider. This ensures that after the slider is located in the guide groove, the surface of the wear-resistant block fits against the inner wall of the guide groove, reducing the gap between the guide and the guide groove, and ensuring the stability of the moving seat when it moves.

[0025] Preferably, at least two guide members are provided, which are distributed at intervals along the length of the frame.

[0026] By adopting the above technical solution, the number of guide components is increased, thereby increasing the contact area between the guide components and the frame. Under the same frictional force, the wear on the guide components is reduced, thus extending the service life of the guide components and the replacement cycle.

[0027] In summary, compared with the prior art, the drilling rig bed assembly of the present invention uses the composite roller bearing in the load-bearing component to bear the pressure from the moving seat, thereby reducing the friction between the moving seat and the frame. This reduces friction and thus reduces the wear between the guide components and the guide rails when the moving seat moves, preventing excessive clearance between them from causing the drill bit to shake during movement and affecting drilling efficiency. The reduced wear also extends the service life of the guide components and guide rails, avoiding the increased drilling costs caused by frequent replacements. Attached Figure Description

[0042] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0043] like Figures 1-13 As shown, the drilling rig bed assembly of the present invention includes a frame 100, which is elongated. A movable seat 200 and a drive mechanism 300 are provided on the frame 100. The drive mechanism 300 is used to drive the movable seat 200 to move along the length direction of the frame 100. In order to ensure the precise movement of the movable seat 200 in a fixed direction, a guide rail 400 and a guide member 500 with sliding engagement are also provided between the movable seat 200 and the frame 100. The sliding engagement between the guide rail 400 and the guide member 500 realizes the movement guidance function of the movable seat 200.

[0044] To reduce wear between the guide rail 400 and the guide member 500 and achieve a precise sliding fit between them, thereby further ensuring that the moving seat 200 can move along the length of the frame 100 when the drive mechanism 300 is running, reducing sway and ensuring drilling accuracy, a load-bearing component is also provided on the moving seat 200. The load-bearing component includes a composite roller bearing 600, in which the main roller 601 and the side roller 602 of the composite roller bearing 600 roll along the length of the frame 100 on the frame 100.

[0045] In the drilling rig bed assembly of the present invention, the pressure from the moving seat 200 is shared by the composite roller bearing 600 in the load-bearing component, thereby reducing the friction between the moving seat 200 and the frame 100, reducing the friction between the guide rail 400 and the guide member 500 during the operation of the drive mechanism 300, reducing wear, ensuring a tight fit between the guide rail 400 and the guide member 500, reducing the gap, thereby reducing the amount of shaking when the moving seat 200 moves, which is beneficial to the stable drilling of the drilling rig; at the same time, since the wear between the guide rail 400 and the guide member 500 is reduced, their service life is extended, and users do not need to frequently replace the guide rail 400 and the guide member 500, thereby reducing drilling costs.

[0046] The specific structure of rack 100 is as follows Figures 1-3 , Figure 6 and Figure 7 As shown, the machine includes two elongated side rods 140 arranged side by side. The two ends of the two side rods 140 are fixedly connected by a front cover 120 and a rear cover 130, respectively. Square tubes 150 with the same length direction are fixedly connected to the upper and lower sides of the side rods 140. On one of the four sides of the outer edge of the square tubes 150, which is adjacent to the gap between the two side rods 140, a wear-resistant strip 160 with the same length direction as the square tube 150 is fixed. The front cover 120, the rear cover 130, the two side rods 140, and the square tubes 150 above and below the side rods 140 and the wear-resistant strips 160 on the square tubes 150 form a strip-shaped hole 101 with the same length direction as the frame 100. The composite roller bearing 600 is rolled inside the strip-shaped hole 101. With the above design, the structure of the drilling machine body assembly is more compact, and the composite roller bearing 600 is protected inside the frame 100 to prevent damage. The bottom surface of the square tube 150 located below is also fixed with a reinforcing strip 230 that runs in the same direction as its length, which is used to reinforce the overall structural strength of the frame 100.

[0047] The cross-sections of the two side rods 140 are U-shaped, meaning that the upper and lower sides of the adjacent surfaces of the two side rods 140 are provided with integrally formed protrusions 701. The two protrusions 701 arranged side by side on the same side rod 140 are combined to form a protrusion assembly 700. There are two sets of composite roller bearings 600 in the load-bearing component. In one set of composite roller bearings 600, the main roller 601 of the composite roller bearing 600 rolls along the length of the frame 100 on the top surface of the upper protrusion 701. In the other set of composite roller bearings 600, the main roller 601 of the composite roller bearing 600 rolls along the length of the frame 100 on the bottom surface of the lower protrusion 701. That is, the protrusion assembly 700 is sandwiched between the main rollers 601 of the two sets of composite roller bearings 600 in the load-bearing component.

[0048] Each of the two sets of composite roller bearings 600 in the load-bearing component includes two composite roller bearings 600 arranged back to back. The side rollers 602 of the two composite roller bearings 600 roll on the wear-resistant strip 160 (that is, the two inner sidewalls of the strip hole 101 in the length direction) along the length direction of the frame 100. In this way, the side rollers 602 on the two composite roller bearings 600 in each set of composite roller bearings 600 are sandwiched between the two inner sidewalls in the length direction of the strip hole 101.

[0049] With the above structure, the two sets of composite roller bearings 600 roll on the top surface of the upper convex strip 701 and the bottom surface of the lower convex strip 701 respectively, thereby preventing the moving seat 200 from wobbling up and down when moving. In each set of composite roller bearings 600, the side rollers 602 of the two composite roller bearings 600 roll along the length of the frame 100 on the adjacent side of the two wear-resistant strips 160. In this way, the moving seat 200 can be prevented from wobbling left and right during the movement, thereby ensuring that the moving seat 200 moves stably along the length of the frame 100 when the drive mechanism 300 is running, reducing the amount of shaking and ensuring drilling accuracy.

[0050] like Figure 8 and Figure 9 As shown, the movable base 200 has three load-bearing components, evenly distributed along the length of the frame 100. Increasing the number of load-bearing components further enhances the load-bearing capacity of the movable base 200, reduces friction between the movable base 200 and the frame 100, thereby reducing wear, extending the service life of the guide 500 and the guide rail 400, and further improving the smoothness of the movable base 200's movement along the length of the frame 100 during the operation of the drive mechanism 300. Of course, as a substitute for a similar effect, the number of load-bearing components on the movable base 200 could also be two, four, or other multiple quantities.

[0051] The specific structure of the movable seat 200 is as follows: Figure 4 , Figure 8 and Figure 9 As shown, the device includes a movable frame 201 mounted on two side rods 140. The movable frame 201 has a U-shaped cross-section with the opening facing downwards. Below the movable frame 201, there are two opposing enclosure frames 202. The two enclosure frames 202 have U-shaped cross-sections facing each other and are respectively positioned above and below the drive mechanism 300. Side plates 203 are fixedly connected to both sides of the movable frame 201, and the two side plates 203 correspond one-to-one with the two side rods 140.

[0052] like Figure 9 , Figure 11 and Figure 12As shown, three composite roller bearings 600 are provided on both sides of the two enclosure frames 202, spaced apart along the length of the frame 100. These three pairs of composite roller bearings 600, spaced apart along the length of the frame 100, combine to form three sets of load-bearing components spaced apart along the length of the frame 100. This enhances the load-bearing effect on the moving seat 200, reduces friction between the moving seat 200 and the frame 100, and reduces wear between the guide rail 400 and the guide component 500 during movement of the moving seat 200. This ensures precise movement of the moving seat 200 in a fixed direction, reduces swaying, improves drilling efficiency, and extends the replacement cycle of the guide rail 400 and the guide component 500. The composite roller bearings 600 are connected to the side of the enclosure frame 202 by a fourth bolt 220, facilitating installation and replacement.

[0053] The drive mechanism 300 includes a hydraulic cylinder, which is located inside the strip-shaped hole 101. The piston rod 302 of the hydraulic cylinder is fixedly connected to the front cover 120, and the cylinder barrel 301 is fixedly connected to the movable seat 200. When the drive mechanism 300 is running, the hydraulic oil in the cylinder barrel 301 is adjusted to drive the piston rod 302 to extend and retract, thereby driving the movable seat 200 to move along the length of the frame 100.

[0054] like Figures 1-4 As shown, the guide rail 400 includes guide grooves 102 extending along the length of the frame 100 and disposed opposite each other on both sides of the frame 100. The two guide grooves 102 correspond one-to-one with the two side rods 140. By providing opposite guide grooves 102 on both sides of the frame 100, the space occupied by the guide rail 400 is reduced, making the drilling rig bed assembly structure more compact.

[0055] Specifically, such as Figure 6 and Figure 7 As shown, each of the two side bars 140 has a notch extending along the length of the frame 100 on its opposite side. A wear-resistant plate 800 is fixedly connected to the inner wall of the notch by a first bolt 180. The wear-resistant plate 800 is elongated, its length aligning with the length of the frame 100, and its cross-section is bent. A guide groove 102 is integrally formed on the side of the wear-resistant plate 800 opposite to the inner wall of the notch, and its shape is "V". The wear-resistant plate 800 is made of stainless steel.

[0056] With the above structure, the guide groove 102 is integrally formed from a wear-resistant stainless steel plate 800. The wear-resistant plate 800 isolates the frame 100 and the guide member 500, preventing the guide member 500 from directly contacting the frame 100 and causing wear on the frame 100 (specifically the side rod 140) when the movable seat 200 slides on the frame 100. The wear-resistant plate 800 is fixedly connected to the side rod 140 of the frame 100 by the first bolt 180, making the connection between the wear-resistant plate 800 and the frame 100 detachable, facilitating replacement of the wear-resistant plate 800 after long-term use.

[0057] like Figure 10 and Figure 11 As shown, three guide members 500 are provided, which are evenly distributed on the side plate 203 along the length of the frame 100. By increasing the number of guide members 500, the contact area between the guide members 500 and the guide groove 102 is increased. Under the condition that the pressure value from the moving seat 200 is fixed, the pressure is reduced after the force-bearing area is increased. At the same time, the three guide members 500 are provided to further enhance the guiding effect between the guide members 500 and the guide groove 102, ensuring that the moving seat 200 can move stably along the length of the frame 100 after the hydraulic cylinder is running.

[0058] The specific structure of guide component 500 is as follows: Figure 10 and Figure 11 As shown, a slider 900, whose elongated direction is aligned with the length direction of the guide groove 102, is slidably disposed within the guide groove 102. The slider 900 is fixedly connected to the side plate 203 of the movable seat 200 via a second bolt 190. The two side walls of the slider 900 are correspondingly fitted with the two inner walls of the guide groove 102 with clearance. Each side wall is provided with a through-groove-shaped insertion port 901, the length direction of which is aligned with the length direction of the slider 900. A wear-resistant block 110 is inserted into the insertion port 901. Baffles 170 are provided at both ends of the insertion port 901, and the baffles 170 are fixedly connected to the slider 900 via a third bolt 210. The baffles 170 serve as limiting plates to prevent the wear-resistant block 110 from moving out of the insertion port 901. Figure 5 As shown, the wear-resistant block 110 is in contact with the inner wall of the guide groove 102.

[0059] The guide component 500 adopts the aforementioned structure formed by combining a slider 900, a wear-resistant block 110, and a baffle 170. The wear-resistant block 110 is in close contact with the inner wall of the guide groove 102, preventing the slider 900 from directly contacting the wear-resistant plate 800 and causing wear on the slider 900. This extends the service life of the guide component 500 and ensures that during long-term use of the equipment, the slider 900 can slide along the guide groove 102 while the moving seat 200 moves stably along the length of the frame 100. The baffle 170 blocks both ends of the insertion port 901 to prevent the wear-resistant block 110 from detaching from the slider 900 during sliding. Furthermore, after the slider 900 is connected to the side plate 203 via the second bolt 190, it is convenient to remove the second bolt 190 after long-term use of the equipment. This allows the slider 900 to be separated from the side plate 203, and the wear-resistant block 110 inside the socket 901 to be replaced before the slider 900 is fixedly connected to the side plate 203. This ensures that the wear-resistant block 110 fits against the inner wall of the guide groove 102 (i.e., the wear-resistant plate 800), ensuring that the moving seat 200 moves stably along the length of the frame 100, preventing deviation or shaking, and improving drilling accuracy.

[0060] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
