[0045] Reference Figures 1 to 6 The boom assembly of the first embodiment of the present invention includes a base 100, a working arm 300 and a bracket 600. The base 100 is hinged to the vehicle body 102, the working arm 300 is hinged to the base 100, and the bracket 600 is connected to the working arm 300. The bracket 600 is used to install drilling equipment; the boom assembly of this embodiment also includes a first drive device 200, a second drive device 400 and a third drive device 500. The first drive device 200 is used to drive the base 100 to rotate around the hinge with the vehicle body 102, the second drive device 400 is used to drive the working arm 300 to rotate around the hinge with the base 100, and the third drive device 500 is used to drive the bracket 600 to rotate.

[0046] In the embodiment of the present utility model, referring to Figure 1 、 Figure 2 、 Figure 6As shown, the base 100 has two hinges, defined for ease of understanding as a first hinge and a second hinge. The first hinge is connected to the vehicle body 102 via a first rotating shaft 101, and the second hinge is connected to the vehicle body 102 via a first drive device 200. The base 100 includes a first structural member 110 and a second structural member 120. The second structural member 120 is connected to the first end of the first structural member 110 in the longitudinal direction, and the first structural member 110 and the second structural member 120 are perpendicular to each other. The first hinge is located at the first end of the first structural member 110 in the longitudinal direction, and the second hinge is located at the second end of the first structural member 110 in the longitudinal direction. Both the first hinge and the second hinge are located on the side of the first structural member 110 facing away from the second structural member 120. The working arm 300 is hinged to the second structural member 120.

[0047] In an embodiment of the present invention, the base 100 is connected to the vehicle body 102 via a first rotating shaft 101, and the working arm 300 is connected to the base 100 via a second rotating shaft 310. The axis of the second rotating shaft 310 extends perpendicularly to the axis of the first rotating shaft 101, thereby enabling the bracket 600 to move in different directions. The length of the first structural member 110 extends parallel to the length of the working arm 300, thereby effectively reducing the size of the arm assembly. The first end of the working arm 300 along its length is hinged to the base 100, and the third drive device 500 is mounted at the second end of the working arm 300 along its length. The third drive device 500 rotates about its own axis to drive the bracket 600 to rotate.

[0048] The boom assembly of the embodiment of the present invention drives the bracket 600 to move through the first drive device 200, the second drive device 400, and the third drive device 500, so that the drilling equipment installed on the bracket 600 has the ability to flexibly adjust the drilling position. The third drive device 500 is configured to rotate around its own axis, which can increase the range of movement of the bracket 600 and thereby increase the coverage of the drilling equipment; the two ends of the working arm 300 are respectively connected to the base 100 and the third drive device 500, which can effectively reduce the volume of the boom assembly and is suitable for all-rock tunnels.

[0049] In the embodiment of the present invention, the first driving device 200 is a hydraulic cylinder, and the two ends of the first driving device 200 are respectively connected to the vehicle body 102 and the base 100; the second driving device 400 is a hydraulic cylinder, and the two ends of the second driving device 400 are respectively connected to the base 100 and the working arm 300. Figure 1 、 Figure 2As shown, the first drive device 200 is a linear hydraulic cylinder, and there are two first drive devices 200, which are respectively connected to the two sides of the base 100 in the width direction, thereby improving the stability of the base 100. The second drive device 400 is also a linear hydraulic cylinder, and there are two second drive devices 400, which are respectively installed on opposite sides of the working arm 300 in the width direction.

[0050] It should be noted that the two first drive devices 200 perform the same action synchronously, that is, the two first drive devices 200 are extended or retracted synchronously to drive the working arm 300 to rotate around the hinge with the base 100; but the two second drive devices 400 do not act synchronously, and the two second drive devices 400 perform opposite actions synchronously, that is, when one of the second drive devices 400 is extended, the other second drive device 400 is retracted, thereby realizing the working arm 300 to swing to both sides in the width direction.

[0051] In this embodiment of the present invention, the third drive device 500 is a rotary reducer. The fixed end of the rotary reducer is connected to the working arm 300, and the movable end of the rotary reducer is connected to the bracket 600. Specifically, the size and power of the rotary reducer can be selected according to actual conditions and are not limited in this embodiment. Using the third drive device 500 as a rotary reducer effectively reduces the volume of the boom support of this embodiment.

[0052] In the embodiment of the present invention, the rotation axis of the third driving device 500 is parallel to the axis of the second rotating shaft 310 .

[0053] In the embodiment of the present invention, the bracket 600 is equipped with a compensation cylinder 610, which is used to drive the drilling equipment installed on the bracket 600 to move along the length direction of the bracket 600. Figure 1 、 Figure 2 As shown, the compensation cylinder 610 is also a linear hydraulic cylinder, and the length extension direction of the compensation cylinder 610 is consistent with the length extension direction of the bracket 600.

[0054] In the embodiment of the present invention, an oil filling groove 311 is provided on the outer peripheral wall of the second rotating shaft 310, an oil filling port 312 is provided at the end of the second rotating shaft 310, an oil filling channel 313 is provided inside the second rotating shaft 310, and the oil filling port 312 is connected to the oil filling groove 311 through the oil filling channel 313. Figures 3 to 5 As shown, when the second shaft 310 is mounted on the base 100, bearings are sleeved at both ends of the length direction of the second shaft 310, and the oil filling groove 311 is set at the position corresponding to the bearing, thereby reducing the friction between the two and extending the service life of the device. Figure 4As shown, the oil injection channel 313 includes a radial section and an axial section. The radial section is connected to the axial section. The oil injection port 312 is set in the axial section of the oil injection channel 313 to facilitate the replenishment of grease into the oil injection channel 313. The radial section is connected to the oil injection groove 311.

[0055] In the embodiment of the present invention, a radially protruding collar 314 is provided at the first end of the second shaft 310 in the longitudinal direction, and a threaded hole for connecting the end cover 320 is provided at the second end of the second shaft 310 in the longitudinal direction. Figure 4 、 Figure 5 As shown, the collar 314 is integrally connected to the second rotating shaft 310. The diameter of the end cap 320 is also larger than that of the second rotating shaft 310. When the second rotating shaft 310 is used to connect the working arm 300 and the base 100, the collar 314 and the end cap 320 are respectively used to limit the ends of the second rotating shaft 310, thereby preventing the second rotating shaft 310 from sliding along its axis. The end cap 320 is provided with a through hole for a bolt to pass through, and the end cap 320 and the second rotating shaft 310 are connected by bolts.

[0056] It is conceivable that the second end of the second rotating shaft 310 in the length direction is not limited to being connected to the end cover 320 by bolts, and can also be connected by means of snaps, buckles, etc.

[0057] The drilling rig of the second embodiment of the present invention includes a vehicle body 102 and the aforementioned boom assembly, with the boom assembly mounted on the vehicle body 102. The drilling rig of this embodiment has a wide coverage area and a high degree of automation for the drilling equipment, thereby reducing machine movement and improving operational efficiency and safety. Furthermore, because the drilling rig includes the aforementioned boom assembly, it possesses at least all the beneficial effects of the boom assembly, which will not be detailed here.
