A bucket holder adapted to a rock drill rig

Abstract

This application proposes a grease bucket bracket adapted for rock drill vehicles, used to fix a grease bucket on the rock drill vehicle frame. It includes: a fixed base having a first mounting surface and a second mounting surface, the extension direction of the first mounting surface intersecting the extension direction of the second mounting surface, so that the fixed base can be installed to different structural mounting positions on the rock drill vehicle frame via the first mounting surface and / or the second mounting surface; and a clamp assembly, disposed on the fixed base and located in a receiving space of the fixed base away from the first and second mounting surfaces, used to hold and position the grease bucket. This solves the technical problem of poor matching degree between existing clamp-type grease bucket brackets and the mounting spaces and layouts of different rock drill vehicle frames due to their simple structure. This allows the grease bucket bracket to flexibly select the installation method according to the actual structure of the rock drill vehicle's tail frame, breaking through the limitation of traditional grease bucket brackets only being applicable to mounting surfaces in a specific direction, and avoiding the need to customize multiple bracket models due to differences in vehicle frame structure.

Description

Technical Field

[0001] This application relates to the technical field of bucket support, and more particularly to a bucket support adapted to a rock drilling vehicle. Background Technology

[0002] Rock drills (also known as borehole drills) are key equipment in tunnel and underground engineering projects using the drill-and-blast method, primarily used for drilling blast holes in rock masses. This equipment is autonomously mobile and can carry multiple rock drills, enabling simultaneous drilling operations at multiple angles and locations, significantly improving drilling efficiency and construction accuracy. A typical rock drill consists of a chassis, a rotating platform, a drill arm system, a feed beam, the rock drill itself, and hydraulic and electrical control systems. In complex and ever-changing underground working environments, rock drills must possess excellent mobility, stability, and high reliability to adapt to different geological conditions and cross-sectional shapes, and are widely used in tunnel excavation projects in railways, highways, water conservancy, and mining.

[0003] During the daily operation of rock drilling rigs, the multiple pin connections between the boom system and the chassis are subjected to various complex alternating loads such as tension, compression, bending, and torsion over long periods. The harsh working environment makes them prone to wear and corrosion. To ensure the flexible rotation and structural durability of each hinge point, these pin connections must be regularly lubricated with grease to form an effective oil film, reducing friction and wear, and preventing corrosion caused by moisture and impurities. Currently, the industry commonly uses centralized or decentralized manual / automatic lubrication systems for grease application. Therefore, a dedicated space must be reserved in the rear frame area of ​​the rock drilling rig for installing a grease can, and a fixed clamp-type can holder made of metal must be installed to securely support the grease can and its supply lines, ensuring stable operation of the lubrication system under vehicle movement and vibration conditions.

[0004] However, existing metal-fixed clamp-type bucket mounts have significant adaptability limitations. Due to structural design differences between rock drills of different models, functions, or manufacturers, the installation space dimensions, layout, and available installation positions of their tailstocks vary, making standardized bucket mounts difficult to use universally. In practical applications, bucket mounts of different shapes and sizes often need to be customized according to the specific structure of each vehicle model, increasing design and manufacturing costs and extending equipment assembly cycles. Therefore, existing bucket mount technologies struggle to achieve cross-vehicle compatibility, hindering the standardization and modularization of lubrication systems. Utility Model Content

[0005] This application provides a bucket support for rock drilling vehicles. By setting a fixed base with multi-directional mounting surfaces and an adaptable clamp assembly, it solves the technical problem of poor compatibility with the installation space and layout of different rock drilling vehicle frames due to the simple structure of existing clamp-type bucket supports. The technical solution is as follows:

[0006] This application provides a grease bucket holder adapted to a rock drill, used to fix a grease bucket on the rock drill frame, comprising: a fixed base having a first mounting surface and a second mounting surface, the extension direction of the first mounting surface intersecting the extension direction of the second mounting surface, so that the fixed base can be installed on different structural mounting positions on the rock drill frame through the first mounting surface and / or the second mounting surface; and a clamp assembly, disposed on the fixed base and located in the receiving space of the fixed base away from the first mounting surface and the second mounting surface, for holding and positioning the grease bucket.

[0007] In one embodiment, the fixing base is configured as an L-shaped structure to form a horizontally arranged first mounting part and a vertically arranged second mounting part on the fixing base. The bottom surface of the first mounting part is the first mounting surface, and the back surface of the second mounting part is the second mounting surface. The second mounting part also has a third mounting surface facing away from the second mounting surface, and the clamp assembly is mounted on the third mounting surface.

[0008] In one embodiment, the first mounting part is provided with a plurality of first mounting holes, which are used to connect the first mounting part to the rock drilling vehicle frame by fasteners; the second mounting part is provided with a plurality of second mounting holes, which are used to connect the second mounting part to the rock drilling vehicle frame by fasteners.

[0009] In one embodiment, the device further includes: two pads symmetrically arranged on the third mounting surface, each pad having two third mounting holes; four anti-loosening bolts adapted to each of the third mounting holes; and a clamp assembly mounted on the two pads through the cooperation of each anti-loosening bolt with the corresponding third mounting hole.

[0010] In one embodiment, the clamp assembly includes: a mounting base having a mounting plate and two mounting lugs connecting to the mounting plate, the mounting plate having four adjusting through holes corresponding one-to-one with the third mounting hole, and each of the two mounting lugs having a through hole; a clamp member passing through the through hole, the clamp member having a tension adjustment function for holding the grease can; and a gasket connected to the ends of the two mounting lugs away from the mounting plate, the gasket having a curved structure with a curved surface adapted to the radial side of the grease can, the gasket being used to fit the grease can in the clamp member.

[0011] In one embodiment, the adjustment through holes are configured as strip structures and extend along the width direction of the second mounting portion. The mounting base can slide on each anti-loosening bolt through each adjustment through hole, thereby adjusting the position of the mounting base on the pad.

[0012] In one embodiment, the clamp includes: a clamp body having an open-loop structure; and a locking bolt disposed at the end of the clamp body for locking the end of the clamp body.

[0013] In one embodiment, a drain outlet is provided on the fixed base, and the drain outlet is located between the first mounting part and the second mounting part.

[0014] Compared to existing technologies, the proposed bucket support for rock drills utilizes a bent base design, forming a first and second mounting surface with an angled extension direction, for example, an L-shape. This allows for flexible installation based on the actual structure of the rock drill's rear frame. Whether the beam is horizontally arranged or the column is vertically positioned, a stable and secure fit can be achieved through the corresponding mounting surface, greatly enhancing the support's adaptability to different vehicle models and installation positions. This design overcomes the limitation of traditional bucket supports being only applicable to mounting surfaces in specific directions, avoiding the need for custom-made supports due to differences in vehicle frame structure, achieving "one type, multiple uses," and reducing design, production, and inventory management costs. The bucket support is detachably connected to the rock drill frame, facilitating transfer and reuse between different devices. Combined with the clamp assembly in the inner accommodating space, it can stably hold the grease drum, ensuring the reliability of the lubrication system during vehicle operation. In special situations where space is limited or higher stability is required, the first and second mounting surfaces can be used simultaneously for double-sided fixing, further enhancing the load-bearing capacity and vibration resistance of the bracket and ensuring the safe operation of the lubrication system.

[0015] In summary, this application not only improves installation efficiency and space utilization, but also promotes the standardization and modularization of lubrication system accessories for rock drills. It has the advantages of reasonable structure, strong versatility, and convenient maintenance, and is suitable for the grease can fixing needs of various types of rock drills, showing good engineering application prospects.

[0032] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0033] Reference Figures 1 to 3 As shown, an embodiment of this application proposes a grease bucket support adapted to a rock drill, used to fix a grease bucket on the frame of the rock drill. The grease bucket support adapted to a rock drill may include: a fixed base 1 having a first mounting surface 111 and a second mounting surface 121, the extension direction of the first mounting surface 111 intersecting the extension direction of the second mounting surface 121, so that the fixed base 1 can be installed on different structural mounting positions on the frame of the rock drill via the first mounting surface 111 and / or the second mounting surface 121; and a clamp assembly 2, disposed on the fixed base 1, located in the receiving space of the fixed base 1 away from the first mounting surface 111 and the second mounting surface 121, for holding and positioning the grease bucket.

[0034] Specifically, in the technical solution adopted in this application, the fixed base 1 can be a rigid component with a bent structure, forming a first mounting surface 111 and a second mounting surface 121 with an included angle on the outer surface of the fixed base 1. Therefore, when installing the fixed base 1 on the rock drill frame, either the first mounting surface 111 or the second mounting surface 121 can be selected to connect with the rock drill frame according to the actual situation, thus adapting to different orientations of the mounting planes on the rock drill frame, such as horizontal beams or vertical columns. The clamping component is configured in the accommodating space inside the fixed base 1 to hold and fix the grease bucket. In use, when the rock drill frame has a horizontal mounting surface, the first mounting surface 111 can be used for contact to detachably install the fixed base 1 onto the rock drill frame; when the rock drill frame has a vertical mounting surface, the second mounting surface 121 is used for contact to detachably install the fixed base 1 onto the rock drill frame; in special cases, both mounting surfaces can be used simultaneously for double fixing.

[0035] Furthermore, refer to Figure 1 As shown, in some embodiments, the fixed base 1 is configured as an L-shaped structure to form a horizontally arranged first mounting part 11 and a vertically arranged second mounting part 12 on the fixed base 1. The bottom surface of the first mounting part 11 is the first mounting surface 111, and the back surface of the second mounting part 12 is the second mounting surface 121. The second mounting part 12 also has a third mounting surface 122 facing away from the second mounting surface 121, and the clamp assembly 2 is mounted on the third mounting surface 122.

[0036] Specifically, in the technical solution adopted in this application, the fixing base 1 can be an L-shaped structure made of thick steel plate bent into shape. The horizontal part of the fixing base 1 is the first mounting part 11, and its lower surface is the first mounting surface 111; the vertical part of the fixing base 1 is the second mounting part 12, and its outer surface is the second mounting surface 121. Furthermore, a third mounting surface 122 is provided on the inner side of the second mounting part 12, and the clamp assembly 2 can be detachably installed on the third mounting surface 122, so that the clamp assembly 2 can be suspended in the receiving space, that is, the semi-enclosed space inside the L-shaped fixing base 1.

[0037] Furthermore, refer to Figure 2 and Figure 3 As shown, in some embodiments, the first mounting part 11 is provided with a plurality of first mounting holes 112, which are used to connect the first mounting part 11 to the rock drill frame by fasteners; the second mounting part 12 is provided with a plurality of second mounting holes 123, which are used to connect the second mounting part 12 to the rock drill frame by fasteners.

[0038] Specifically, in the technical solution adopted in this application, the first mounting part 11 has first mounting holes 112 arranged in a rectangle, so that the first mounting part 11 can be connected to the frame using hexagonal bolts; the second mounting part 12 has second mounting holes 123 arranged in a rectangle, so that bolts of the same specification can be used to achieve vertical fixation. Thus, in this embodiment, the first method of removing the grease can from the rock drilling vehicle frame is to detach the grease can along with the bucket support of this application from the rock drilling vehicle frame.

[0039] Furthermore, refer to Figure 4 As shown, in some embodiments, it further includes: two pads 3, symmetrically arranged on the third mounting surface 122, each pad 3 having two third mounting holes 31; four anti-loosening bolts 4, adapted to each third mounting hole 31; and the clamp assembly 2 is installed on the two pads 3 by the cooperation of each anti-loosening bolt 4 with the corresponding third mounting hole 31.

[0040] Specifically, in the technical solution adopted in this application, two pads 3 are added to strengthen the structural connection and are symmetrically welded to both sides of the third mounting surface 122. Each pad 3 is provided with two third mounting holes 31 and equipped with four anti-loosening bolts 4 and spring washers; the clamp assembly 2 is connected to the pads 3 through the anti-loosening bolts 4, thereby achieving the effect of preventing vibration and loosening. Thus, in this embodiment, a second method of removing the grease can from the rock drill frame is formed, namely: the grease can, together with the clamp assembly 2, is removed and separated from the rock drill frame.

[0041] Furthermore, refer to Figure 4 As shown, in some embodiments, the clamp assembly 2 includes: a mounting base 21 having a mounting plate and two mounting lugs connecting the mounting plate, the mounting plate having four adjusting through holes 211 corresponding one-to-one with the third mounting hole 31, and each of the two mounting lugs having a through hole 212; a clamp 22 passing through the through hole 212, the clamp 22 having a tension adjustment function for holding the grease bucket; and a gasket 23 connected to the ends of the two mounting lugs away from the mounting plate, the gasket 23 being a curved structure with a curved surface adapted to the radial side of the grease bucket, the gasket 23 being used to fit the grease bucket in the clamp 22.

[0042] Specifically, in the technical solution adopted in this application, the mounting base 21 can be composed of a mounting plate and two mounting ears vertically welded to the mounting plate. An adjustment through hole 211 is opened on the mounting plate. When the adjustment through hole 211 on the mounting plate is aligned with the third mounting hole 31, the mounting plate is fixed to the pad 3 by the anti-loosening bolt 4. The clamp 22 can be a stainless steel hose clamp, which is inserted into the through hole 212 on the mounting ear. The gasket 23 is an arc-shaped plate formed by stamping process, which is welded to the end of the mounting ear and can fit completely against the outer wall of the grease bucket.

[0043] Furthermore, refer to Figure 4 As shown, in some embodiments, the adjustment through hole 211 is configured as a strip structure and extends along the width direction of the second mounting part 12. The mounting base 21 can slide on each anti-loosening bolt 4 through each adjustment through hole 211, thereby adjusting the position of the mounting base 21 on the pad 3.

[0044] Specifically, in the technical solution adopted in this application, the strip-shaped adjustment through hole 211 on the mounting plate extends along the width direction of the fixed base 1, that is, in the horizontal direction. In use, after loosening the anti-loosening bolt 4, the horizontal position of the clamp assembly 2 can be adjusted by sliding the mounting base 21, so that the grease bucket fixed by the bucket bracket of this application can be more adapted to the rock drilling vehicle frame structure under different conditions.

[0045] Furthermore, refer to Figure 4 As shown, in some embodiments, the clamp 22 includes: a clamp body 221, which has an open-loop structure; and a locking bolt 222, which is disposed at the end of the clamp body 221 and is used to lock the end of the clamp body 221.

[0046] Specifically, in the technical solution adopted in this application, the clamp body 221 can be made of stainless steel strip; while the locking bolt 222 can be a threaded head fixed to one end of the clamp body 221 and a tightening nut fixed to the other end of the clamp body 221, so that the diameter of the clamp ring can be adjusted by rotating the nut. Thus, in this embodiment, a third method of removing the grease can from the rock drill frame is formed: the clamp body 221 is opened by the locking bolt, and the grease can is directly disassembled and separated from the rock drill frame.

[0047] Furthermore, refer to Figures 1 to 4 As shown, in some embodiments, the fixed base 1 is provided with a drain outlet 13, which is located between the first mounting part 11 and the second mounting part 12.

[0048] Specifically, in the technical solution adopted in this application, a drain outlet 13 is provided at the L-shaped bend of the fixed base 1. It can be located at the lowest point of the junction of the first mounting part 11 and the second mounting part 12 to drain accumulated grease or rainwater, thereby achieving the effect of preventing corrosion of the fixed base 1.
