Description

Technical Field

[0001] This application relates to the field of coal mine roadway support technology, and in particular, to an integrated rock bolt drilling rig. Background Technology

[0002] The information provided in this section is for the purpose of generally presenting the background of this application. To the extent described in this section, the work of the currently named inventors and aspects of the description that may not constitute prior art at the time of filing are neither explicitly nor implicitly considered to be prior art of this application.

[0003] Anchor bolt drilling rigs are key components for supporting coal mine roadways, enabling drilling, bolting, and cable installation. Their structure and quality significantly impact support efficiency and roadway safety. For example, Chinese patent CN117005810A discloses an anchor bolt drilling rig where the second slide rail supports one end of the clamp, effectively reducing eccentric load and mitigating deformation of the first slide rail due to eccentric load, allowing for smooth extension and retraction. However, this type of anchor bolt drilling rig is bulky, with externally mounted hydraulic lines, making it susceptible to damage from impacts and line breaks, leading to oil leaks. Furthermore, the anchor bolt drilling rig and valve body are separate components.

[0004] Existing anchor bolt drilling rigs typically have their operating valve assemblies, such as plate valves, installed separately from the drilling rig itself. This necessitates an additional control panel to house the valve bodies and operate the anchor bolt drilling rig. The control panel required for anchor bolt drilling rigs occupies a significant area, and the connection between the operating valve assemblies and the drilling rig via hydraulic pipes results in numerous and complex piping systems. Furthermore, the external hydraulic piping supplying the bolting mechanism makes these exposed lines susceptible to damage from falling coal or other equipment during operation, leading to oil leaks. Damage to the hoses requires lengthy replacement and repair processes, resulting in significant hydraulic oil leakage and the risk of secondary contamination of the hydraulic system. These factors severely impact the service life of the anchor bolt drilling rig and its anchoring efficiency. Utility Model Content

[0018] This integrated anchor drilling rig connects the operating valve assembly to the drilling rig body via a connecting plate assembly. The drilling rig body has an internal oil passage for supplying oil to various components. The operating valve assembly is connected to this internal oil passage, thus integrating the operating valve assembly with the drilling rig body.

[0024] The embodiments of this application are described in detail below with reference to the accompanying drawings; however, this application may be implemented in a variety of different ways as defined and covered below.

[0025] Figure 1 This is a schematic diagram of the overall structure of a preferred embodiment of this application; Figure 2 This is a schematic diagram of the installation of the operating valve assembly according to a preferred embodiment of this application.

[0026] An integrated anchor bolt drilling rig includes a drilling rig body 1, a primary propulsion mechanism 2, a secondary propulsion mechanism 3, a rotary drive mechanism 4, and a base plate 6. The rotary drive mechanism 4 is used to install drill rods. The secondary propulsion mechanism 3 is connected to the rotary drive mechanism 4 and is used to drive the rotary drive mechanism 4 to move along the drilling direction. The primary propulsion mechanism 2 is connected to the secondary propulsion mechanism 3 and is used to drive the secondary propulsion mechanism 3 to move along the drilling direction. The primary propulsion mechanism 2 is mounted on the drilling rig body 1. The base plate 6 is slidably connected to the drilling rig body 1. The base plate 6 is provided with a clamping mechanism for supporting and limiting the drill rods. The integrated anchor bolt drilling rig also includes an operating valve assembly 5, a connecting plate assembly 9, and a hydraulic manifold block 10.

[0027] The drilling rig body 1 has a body oil passage. The operating valve assembly 5 is connected to the drilling rig body 1 through the connecting plate assembly 9, and the operating valve assembly 5 is connected to the body oil passage. The oil passage block 10 is set on the drilling rig body 1. The oil passage block 10 is used to connect the external liquid inlet pipe and connect the liquid inlet pipe to the body oil passage.

[0028] Here, "oil manifold 10" refers to the structure that connects to the drilling rig body 1 and connects the external pipeline to the drilling rig body 1. In some embodiments, the oil manifold 10 is a block or plate structure. Since this application directly arranges the operating valve assembly 5 on the anchor drilling rig frame, i.e. the drilling rig body 1, there are only three pipelines connecting the anchor drilling rig from outside the system. That is, it is only necessary to connect the external oil inlet pipeline, the oil return pipeline, and the cooling water pipeline to the oil manifold 10 to connect to the drilling rig body 1.

[0029] Here, "rotary drive mechanism 4" means a mechanism for mounting and driving the drill pipe to rotate. In some embodiments, the rotary drive mechanism 4 includes a motor.

[0030] It should be noted that current anchor drilling rig designs focus on internal hydraulic circuitry. However, existing structural designs have several drawbacks, including complex internal oil passages that are difficult to manufacture, maintain, and repair, increasing the risk of hydraulic oil leakage; excessively long internal oil passages leading to oil pressure loss and insufficient cylinder thrust; external placement of the feed hydraulic lines for the drill bit support device; and excessively large anchor drilling rig sizes. Furthermore, most current anchor drilling rigs have separate bodies for the main body and operating valves, a problem that needs to be addressed in current anchor drilling rig structural design.

[0031] This application focuses on how to reduce the operating platform area of ​​the anchor bolt drilling rig, increase the working range of the anchor bolt drilling rig, and avoid oil leakage problems. This application connects the operating valve assembly 5 to the drilling rig body 1 via the connecting plate assembly 9. The drilling rig body 1 has an internal oil passage for supplying oil to various components. The operating valve assembly 5 is connected to the oil passage, thus integrating the operating valve assembly 5 with the drilling rig body 1. This integration of the valve assembly with the anchor bolt drilling rig body effectively reduces the volume of the operating platform, increases the platform area, and expands the operating space for personnel. Furthermore, an oil passage block 10 is installed on the drilling rig body 1. An external pipeline is connected to the oil passage through the oil passage block 10, supplying oil or water to the drilling rig body 1. Combined with the integration of the operating valve assembly 5 with the drilling rig body 1, this effectively reduces the need for external hydraulic hoses, minimizing hydraulic oil leakage caused by hose wear and compression, and effectively improving oil leakage or hydraulic system contamination in the anchor bolt drilling rig.

[0032] In one embodiment, the connecting plate assembly 9 includes a first connecting plate 91, an operating valve assembly 5 is installed on a first side of the first connecting plate 91, a second side of the first connecting plate 91 is fitted and connected to the drilling rig body 1, a first connecting pipe is provided in the first connecting plate 91, the first connecting pipe is connected to the pipeline of the operating valve assembly 5 and is used to connect the oil passage of the operating valve assembly 5 with the oil passage of the body.

[0033] It is understandable that after the operating valve assembly 5 is installed via the first connecting plate 91, the first connecting plate 91 and the operating valve assembly 5 are then installed together onto the drilling rig body 1. The operating valve assembly 5 can be disassembled and assembled by removing and installing the first connecting plate 91. At the same time, the first connecting pipe inside the first connecting plate 91 is connected to the pipeline of the operating valve assembly 5, and the oil passage of the operating valve assembly 5 is connected to the oil passage of the drilling rig body 1, thereby reducing the need for external oil pipes and reducing malfunctions such as hydraulic oil leakage caused by wear and compression of hydraulic oil pipes.

[0034] In another embodiment, please refer to Figure 1As shown, the connecting plate assembly 9 includes a first connecting plate 91 and a second connecting plate 92. The operating valve assembly 5 is installed on the first side of the first connecting plate 91. The first side of the second connecting plate 92 is in close contact with the drilling rig body 1. The second side of the second connecting plate 92 is connected to the second side of the first connecting plate 91. A second connecting pipe is provided in the second connecting plate 92. The second connecting pipe is connected to the pipeline of the operating valve assembly 5 and is used to connect the oil passage of the operating valve assembly 5 with the oil passage of the body.

[0035] It is understood that in this embodiment, the operating valve assembly 5 is installed through the second connecting plate 92, and the second connecting pipe inside the second connecting plate 92 is connected to the pipeline of the operating valve assembly 5 and communicates with the oil passage of the main body. Therefore, the second connecting plate 92 can be flexibly designed with various structures to adapt to the operating valve assembly 5, so as to facilitate the installation of different operating valve assemblies 5 by replacing the second connecting plate 92. The second connecting plate 92 plays a role in stabilizing the installation of the operating valve assembly 5. Finally, the second connecting plate 92 is connected to the first connecting plate 91, so that the second connecting plate 92 and the operating valve assembly 5 can be installed on the rotating body 1, which facilitates the disassembly, assembly and maintenance of the operating valve assembly 5.

[0036] It should be noted that the operating valve assembly 5 is a plate valve assembly of the anchor drilling rig. Traditionally, the plate valve assembly is installed separately from the anchor drilling rig, so an additional operating table is required to install the valve assembly and operate the anchor drilling rig. The operating table required by the anchor drilling rig occupies a large area, and the valve assembly needs to be connected to the anchor drilling rig by oil pipes, which is prone to problems such as wear and leakage of external pipelines. However, this application integrates the operating valve assembly 5 by connecting plate assembly 9, which can effectively solve these problems.

[0037] Preferably, please refer to Figure 1 and 2 As shown, the integrated anchor drilling rig also includes a guide rod 7 and a strut cylinder. The guide rod 7 is set on the drilling rig body 1 along the drilling direction. The base plate 6 is sleeved on the guide rod 7. The strut cylinder is set on the drilling rig body 1. The strut cylinder is connected to the base plate 6 through the strut cylinder rod 8. The strut cylinder is used to push the base plate 6 to move.

[0038] Understandably, the strut cylinder is connected to the base plate 6 via the strut cylinder rod 8, enabling the strut cylinder to push the base plate 6 to move. The guide rod 7 guides the base plate 6 to slide, making the sliding movement of the base plate 6 along the drilling direction more stable and the position control more precise.

[0039] In this preferred embodiment, the oil pipe of the strut cylinder is connected to the body oil passage inside the drilling rig body 1.

[0040] Understandably, since the drilling rig body 1 has a body oil passage, which is connected to the strut cylinder, the number of external oil pipes can be reduced. In conjunction with the operation valve assembly 5, which is directly connected to the drilling rig body 1 and communicates with the body oil passage, the operation valve assembly 5 can achieve faster and more precise operation control and reduce the impact of oil leakage.

[0041] Preferably, the guide rod 7 is provided with a guide mounting groove, and a guide oil pipe is provided in the guide mounting groove. The guide oil pipe is used to connect the body oil passage with the oil passage of the clamping mechanism.

[0042] Understandably, by incorporating a guide oil pipe into the guide rod 7 and supplying oil to the clamping mechanism through the guide oil pipe, the number of external oil pipes is further reduced, the structure is simplified in multiple ways, and all aspects of the anchor drilling rig are ensured to avoid oil leakage or hydraulic system contamination.

[0043] In this preferred embodiment, the guide oil pipe is a telescopic pipe structure.

[0044] Understandably, since the base plate 6 will slide along the drilling direction, in order to improve the connection stability between the guide oil pipe and the base plate 6 and avoid friction and wear caused by the reciprocating movement of the guide oil pipe in the form of a hose, the guide oil pipe is designed as a telescopic pipe structure. This can achieve more stable oil supply and avoid wear caused by frequent bending, which is conducive to improving service life.

[0045] It should be noted that the guide oil pipe of the telescopic tube structure is sealed with guide seals such as guide sealing sleeves to ensure the reliability of the seal inside the guide oil pipe.

[0046] Preferably, the primary propulsion mechanism 2 includes a primary propulsion cylinder, and the secondary propulsion mechanism 3 includes a secondary propulsion cylinder. The oil pipes of the primary propulsion cylinder and the secondary propulsion cylinder are respectively connected to the main body oil passage in the drilling rig body 1.

[0047] Understandably, by connecting the pipelines of the first-stage and second-stage propulsion cylinders to the main hydraulic system, the length of external hydraulic pipes can be reduced in all places, the number of exposed hydraulic pipes can be reduced, and the damage or aging of external hydraulic pipes can be effectively avoided, which could lead to problems such as oil leakage or secondary pollution of the hydraulic system.

[0048] Preferably, please refer to Figure 1 As shown, the first-stage propulsion cylinder is connected to the drilling rig body 1 via the first piston rod 21, and the second-stage propulsion cylinder is connected to the first-stage propulsion cylinder via the second piston rod.

[0049] Understandably, the secondary propulsion cylinder is connected to the primary propulsion cylinder, and then the primary propulsion cylinder is connected to the drilling rig body 1. After the secondary propulsion mechanism 3 is connected to the primary propulsion mechanism 2, the primary propulsion mechanism 2 is connected to the drilling rig body 1, thereby realizing multi-stage propulsion motion to meet the needs of different drilling holes. Both the primary propulsion mechanism 2 and the secondary propulsion mechanism 3 are connected to the body oil passage. With the direct connection of the operating valve assembly 5 to the drilling rig body 1, rapid response control of the primary propulsion mechanism 2 and the secondary propulsion mechanism 3 can be achieved, reducing oil leakage or hydraulic system contamination and ensuring the stability of the overall operation.

[0050] Preferably, the oil manifold 10 is provided with an oil inlet, an oil return outlet, and a cooling water inlet. The oil inlet is used to connect an external oil inlet pipeline and is connected to the inlet of the main body oil passage. The oil return outlet is used to connect an external oil return pipeline and is connected to the outlet of the main body oil passage. A cooling water channel is also provided inside the drilling rig body 1. The cooling water inlet of the oil manifold 10 is used to connect an external cooling water pipe and is connected to the cooling water channel.

[0051] Understandably, since this application directly arranges the operating valve assembly 5 on the drilling rig body 1, i.e. the anchor drilling rig frame, the pipelines connecting the anchor drilling rig from outside the system are only three pipelines: oil inlet, oil return, and cooling water. This effectively reduces the number of connecting pipelines, reduces the complexity of the drilling rig's pipeline connections, avoids damage or aging of external oil pipes, and reduces the space required for the operating valve assembly and the operating platform.

The examples are merely for the purpose of helping to understand the method and core ideas of this application. The above descriptions are only preferred embodiments of this application.
