[0001] This application relates to the field of tunnel construction technology, and in particular to a telescopic rock drilling rig slide device. Background Technology

[0002] In tunnel construction, especially in mining surface construction, frequent drilling of blast holes and anchor bolt holes is required. Due to the limited space in tunnels and the fixed drilling depth requirements, the rock drilling rig used for blasting cannot perform the same function as the anchor bolt hole drilling. Therefore, different equipment is needed to complete the tasks of blasting and anchor bolt hole drilling: rock drilling rigs and drilling machines are used for blasting, while anchor bolt holes require anchor bolt rigs. This causes great inconvenience to the construction, results in serious resource waste, and high costs. To address this, this application proposes a retractable rock drilling rig sliding device that can simultaneously perform blasting and anchor bolt hole drilling operations with a single machine, thereby solving the above-mentioned drawbacks.

[0021] This application provides a telescopic rock drilling rig slide rail device, such as Figure 1-3 As shown, it includes:

[0022] Connector 100 is used to connect to the host machine and can be fixedly or rotatably connected to the mechanical chassis or other robotic arms.

[0023] The swing arm 200 is connected to the connecting seat 100 and can swing.

[0024] The support assembly 300 is movably connected to the free end of the swing arm 200;

[0025] The slide rail assembly 400 is disposed on the support assembly 300 and includes a primary slide rail 410 and a secondary slide rail 420. The secondary slide rail 420 is slidably disposed on the primary slide rail 410 and can move along the primary slide rail 410.

[0026] A rock drill 500 is provided on the secondary slide rail 420, and the rock drill 500 can move along the secondary slide rail 420.

[0027] For example, in the telescopic rock drilling rig slide device provided in one embodiment, such as Figure 1 As shown, a propulsion motor 421 is provided at one end of the secondary slide rail 420 to drive the rock drill 500 to move along the secondary slide rail 420. The rock drill 500 is used to install the steel drill bit 510. In actual operation, the rotation and impact of the rock drill 500 drive the steel drill bit 510 to drill holes in the rock. A main drill clamp 422 for supporting the steel drill bit 510 is provided at the end of the secondary slide rail 420 away from the propulsion motor 421.

[0028] The secondary slide rail 420 is equipped with a screw that works in conjunction with the propulsion motor 421 to drive the rock drill 500 to move along the secondary slide rail 420. The drive mechanism that drives the rock drill 500 to move along the secondary slide rail 420 can also be implemented using various structures such as hydraulic cylinders, chains, and wire ropes.

[0029] For example, in the telescopic rock drilling rig slide device provided in one embodiment, such as Figure 1-2 As shown, slide rail telescopic arms 600 are provided on both sides of the secondary slide rail 420 along the axial direction. The slide rail telescopic arms 600 are fixedly connected to the secondary slide rail 420 and can extend or retract along the axial direction of the secondary slide rail 420. A secondary rod clip 610 for supporting the steel rod 510 is provided at the free end of the slide rail telescopic arm 600.

[0030] The slide rail telescopic arm 600 can be a hydraulic cylinder liner, a hydraulic cylinder piston, or a sliding telescopic structure with inner and outer sleeves. Figure 2 In the embodiment shown, the slide rail telescopic arm 600 is a cylinder liner for two hydraulic cylinders. The slide rail telescopic arm 600 is fixed by a secondary bracing clip 610 at its free end to prevent it from rotating.

[0031] The main drill bit clamp 422 and the auxiliary drill bit clamp 610 are used to stabilize the steel drill bit 510 when supporting and changing the drill bit.

[0032] For example, in the telescopic rock drilling rig slide device provided in one embodiment, such as Figure 1As shown, a slider 423 is provided on the secondary slide rail 420. The rock drill 500 is located on the slider 423 and is detachably connected to the slider 423. The slider 423 is driven to move along the secondary slide rail 420 by the propulsion motor 421, which in turn drives the rock drill 500 to move along the secondary slide rail 420.

[0033] Specifically, the bottom of the secondary slide rail 420 is slidably connected to the primary slide rail 410, and the bottom of the secondary slide rail 420 is equivalent to a slider that can slide along the primary slide rail 410; the top surface of the secondary slide rail 420 is a groove for the slider 423 that drives the rock drill 500 to move.

[0034] For example, in the telescopic rock drilling rig slide device provided in one embodiment, such as Figure 1 As shown, a push cylinder 411 is provided at one end of the primary slide rail 410 to drive the secondary slide rail 420 to move along the primary slide rail 410, so that the auxiliary drill bit 610 completes the initial positioning of the rock drill 500 on the uneven working surface and the secondary contacting of the auxiliary drill bit 610 with the rock surface during drilling.

[0035] For example, in the telescopic rock drilling rig slide device provided in one embodiment, such as Figure 1 As shown, a support cylinder 412 is provided at the bottom of the primary slide rail 410 to support the slide rail assembly 400 on the ground.

[0036] According to the above embodiment, by setting a support cylinder 412 at the bottom of the first-stage slide rail 410, when the rock drill 500 needs to drill upwards, the support cylinder 412 extends and pushes against the ground, which plays a stabilizing and protective role for the whole machine.

[0037] For example, in the telescopic rock drilling rig slide device provided in one embodiment, such as Figure 1 As shown, the support component 300 includes:

[0038] The support base 310 is hinged to the free end of the swing arm 200 and can rotate around the hinge axis to adjust the tilt angle of the slide rail assembly 400.

[0039] A rotary support 320 is located on top of the support base 310 and connected to the primary slide rail 410 to drive the slide rail assembly 400 to rotate horizontally.

[0040] For example, in the telescopic rock drilling rig slide device provided in one embodiment, such as Figure 1As shown, a rotary cylinder 311 is provided on the swing arm 200 to drive the support base 310 to rotate. The output end of the rotary cylinder 311 is connected to the support base 310, driving the support base 310 to rotate around the hinge axis to adjust the tilt angle of the slide rail assembly 400.

[0041] According to the above embodiments, the vertical angle and / or parallel adjustment of the support seat 310 is completed by the rotating cylinder 311 to adjust the tilt angle or slope of the slide rail assembly 400; the horizontal rotation of the slide rail assembly 400 is completed by the rotating support 320 to drill blast holes and anchor bolt holes on the rock surface at different angles.

[0042] Among them, the support base 310 and the rotary support 320 can use various structural forms such as pin sleeve rotation and rotary cylinder rotation, and different forms can be selected according to user needs.

[0043] For example, in the telescopic rock drilling rig slide device provided in one embodiment, such as Figure 1 As shown, the swing arm 200 is hinged to the connecting seat 100. The connecting seat 100 is provided with a swing cylinder 210 for driving the swing arm 200 to swing. The output end of the swing cylinder 210 is connected to the swing arm 200, and the swing arm 200 is driven to swing through the swing cylinder 210.

[0044] For example, in the telescopic rock drilling rig slide device provided in one embodiment, such as Figure 1 As shown, the connecting seat 100 is connected to the host through a rotary joint 700, that is, the connecting seat 100 is rotatably connected to the mechanical chassis or other mechanical arm through the rotary joint 700.

[0045] The method of using the telescopic rock drilling rig slide device of this application in the construction process of drilling blast holes and anchor bolt holes is as follows: When drilling blast holes, first, with the cooperation of the propulsion motor 421, the rock drill 500 is pulled to the end of the secondary slide rail 420, that is, the initial position. Then, the slide telescopic arm 600 is extended to the appropriate length of the steel rod 510. With the cooperation of the push cylinder 411, the primary slide rail 410 is moved so that the auxiliary rod clamp 610 is in close contact with the working surface. The rock drill 500 is started to work, and at the same time, the propulsion motor 421 starts to work and starts the drilling task.

[0046] When the rock drill 500 reaches the position of the main drill bit 422 and can no longer move forward, the rock drill 500 is pulled back to the end of the secondary slide rail 420 by the push motor 411, the slide rail telescopic arm 600 is retracted, the push cylinder 411 is started, the primary slide rail 410 is pushed forward, so that the auxiliary drill bit 610 is in close contact with the working face again, and the rock drill 500 and the push motor 411 are started again to drill forward and complete the blasting process.

[0047] When drilling anchor bolt holes, due to the limited tunnel height, the slide rail assembly 400 may be too long to work, while the required depth of the anchor bolt hole is not deep. In this case, the slide rail telescopic arm 600 can be retracted, a suitable short steel chisel 510 can be replaced, and the drilling action can be repeated to successfully complete the anchor bolt hole drilling work. When drilling anchor bolt holes, the entire slide rail assembly 400 may be in a suspended state, with the force direction being the same as or perpendicular to the force direction of the swing arm 200. The entire machine may be in a swaying state, which is not conducive to the protection of the machine. In this case, the support cylinder 412 can be extended and pressed against the ground to fix and protect the machine.

[0048] The telescopic rock drilling rig slide device of this application can simultaneously perform the functions of drilling blast holes and drilling anchor bolt holes, without the need to use different equipment for operation, reducing construction costs and bringing great convenience to engineering construction.

[0049] Although the embodiments of this application have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this application. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this application is not limited to the specific details and the illustrations shown and described herein.
