Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, and in particular to a drilling machine robotic arm. Background Technology

[0002] A drilling rig is a high-efficiency pile foundation construction equipment. Its working principle is to operate the swing and extension of the mechanical arm to adjust the direction of the excavator drive unit, and drive the excavator drive unit to rotate and cut the soil or rock through the power head. The extension and retraction excavator drive unit is used to lift and lower the drill bucket to complete the excavation operation.

In the construction process, in addition to digging, it is also necessary to lift heavy construction objects, requiring additional lifting equipment. Therefore, enabling the robotic arm of a drilling rig to switch between digging and lifting functions is an urgent problem to be solved, hence this application. Utility Model Content

The second side frame has a support rod. A second robotic arm is telescopically mounted on the first robotic arm. An end cap is fixedly mounted on one end of the second robotic arm. The first side frame is fixedly mounted on one outer wall of the end cap. The first side frame has a support opening. The walking switching frame has a frame opening inside, and multiple wear-resistant pads are provided on the inner wall of the frame opening. The walking switching frame is movably nested on the second robotic arm, and the multiple wear-resistant pads on the inner wall of the walking switching frame are all attached to the surface of the second robotic arm. A side frame and two limiting baffles are fixedly installed on one side of the frame. The rotating hook assembly is installed on the side frame of the travel switching frame. When the rotating hook assembly hooks onto the frame rod, it is in the first locked state, at which time the travel switching frame is fixed to the first robotic arm; when the rotating hook assembly hooks into the frame opening, it is in the second locked state, at which time the travel switching frame is fixed to the second robotic arm. An elastic connection component is installed inside the walking switching frame. The elastic connection component is elastically connected to the rotating hook component, which facilitates the rotating hook component to return to its original position. Preferably, the end of the second robotic arm has a mounting portion for mounting a hook.

[0006] Preferably, the multiple wear-resistant pads on the inner wall of the walking switching frame opening are made of special engineering materials.

[0007] Preferably, the rotating hook assembly includes: The rotating drum is mounted between the travel switching frame and the side frame. The first hook plate is fixedly installed on the outer wall of the rotating drum located inside the side frame. It has a hook bend portion that hooks onto the frame rod on the second side frame of the first robotic arm. The second hook plate is fixedly installed on one side of the rotating drum inside the travel switching frame. It is located in the gap between the travel switching frame and the second robotic arm, and between two adjacent wear-resistant pads on the inner wall of the travel switching frame opening. It has a hook-shaped part. The side plate is fixedly installed on the outer side wall of the rotating cylinder located inside the side frame; A hinge plate, one end of which is hinged to one side of the side plate via a pivot, is located between two limiting baffles on one side of the walking switching frame, and the bottom end of the hinge plate has a port.

[0009] Preferably, the first side frame has a rod at the frame opening, and the hook bend of the second hook plate can hook onto the rod at the frame opening.

[0010] Preferably, the drilling assembly includes: The mounting rod is rotatably mounted on the bottom inner wall of the travel switching frame. A motor is provided on one outer wall of the travel switching frame, and the output shaft of the motor is fixedly mounted on the mounting rod.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Traditional drilling rigs typically have only one digging rod drive unit at the end of their robotic arm, enabling only single-function digging operations. However, during construction, in addition to digging, lifting heavy construction objects is also required, necessitating additional lifting equipment. Therefore, enabling the drilling rig's robotic arm to switch between digging and lifting functions is a pressing issue. This embodiment discloses a drilling rig robotic arm for operating the digging assembly 500 to perform deflection and swinging movements; including: Figure 1 The first robotic arm 100, the walking switch frame 200, the rotating hook assembly 300, and the elastic connection assembly 400 are shown.

[0016] like Figure 1 As shown, the first robotic arm 100 is mounted on the chassis rotary platform of the drilling rig. The second robotic arm 110 is telescopically mounted on the first robotic arm 100. The relative movement of the first robotic arm 100 and the second robotic arm 110 is driven by a hydraulic transmission system to complete the extension or retraction of the first robotic arm 100 and the second robotic arm 110 (this is a very mature technology in the prior art, and the specific operation method will not be described again).

[0017] like Figure 4 and Figure 5 As shown, the walking switching frame 200 has a frame opening, and the inner wall of the frame opening is provided with multiple wear-resistant pads 210. The wear-resistant pads 210 are special engineering material pads with wear resistance, temperature resistance, corrosion resistance and cushioning functions. The walking switching frame 200 is movably nested on the second robotic arm 110, and the multiple wear-resistant pads 210 on the inner wall of the frame opening of the walking switching frame 200 are all attached to the surface of the second robotic arm 110, so that the walking switching frame 200 can slide on the second robotic arm 110.

[0018] like Figure 1 As shown, in order to realize the drilling operation of the drilling machine, the drilling component 500 is set on the bottom side of the travel switching frame 200; when the first mechanical arm 100 and the second mechanical arm 110 of the drilling machine are adjusted, the drilling component 500 can be adjusted to realize the drilling operation of the soil. The drilling assembly 500 includes: a mounting rod 510 and a drilling rod drive unit 520; the mounting rod 510 is rotatably mounted on the bottom inner wall of the travel switching frame 200, and a motor is provided on one outer wall of the travel switching frame 200. The output shaft of the motor is fixedly mounted on the mounting rod 510, thereby driving the mounting rod 510 to produce an angular deflection; the drilling rod drive unit 520 is mounted on the mounting rod 510. The drilling rod drive unit 520 has the functions of deflection (adjusting the lateral offset of the working position) and rotation (driving the drill bit to cut the soil). The rotation of the drill bit relies on the "power head + hydraulic / mechanical transmission" to provide cutting torque, and the core is to drive the drill bit to break the strata; the deflection is achieved by the "hydraulic cylinder + hinge mechanism" to achieve lateral position fine adjustment, and the core is to improve the flexibility of operation and positioning accuracy (this is a very mature technology in the prior art, and the specific operation method will not be described in detail here).

[0019] like Figure 4 and Figure 5 As shown, in order to install the rotating hook assembly 300, a side frame 220 is fixedly installed on one side of the travel switching frame 200, the rotating hook assembly 300 is set on the side frame 220 on one side of the travel switching frame 200, and two limiting baffles 230 are fixedly installed on the outer wall of one side of the travel switching frame 200. The rotating hook assembly 300 includes: a rotating drum 310, a first hook plate 320, a second hook plate 330, a side plate 340, a hinge plate 350, and a roller 360; the rotating drum 310 is rotatably mounted between the travel switching frame 200 and the side frame 220; the first hook plate 320 is fixedly mounted on the outer side wall of the rotating drum 310 located inside the side frame 220, and has a hook bend portion thereon; the second hook plate 330 is fixedly mounted on one side of the rotating drum 310 located inside the travel switching frame 200, and is positioned between the travel switching frame 200 and the second robotic arm 11. Within the gap between 0, and located between two adjacent wear-resistant pads 210 on the inner wall of the travel switching frame 200, it has a hook-bent part; the side plate 340 is fixedly installed on the outer side wall of the rotating cylinder 310 located inside the side frame 220; one end of the hinge plate 350 is hinged to one side of the side plate 340 via a rotating shaft, located between two limiting baffles 230 on one side of the travel switching frame 200, and the bottom end of the hinge plate 350 has a port; the roller 360 is rotatably installed on the inner wall of the port at the bottom end of the hinge plate 350 via a rotating shaft; like Figure 2 As shown, when the rotating hook assembly 300 needs to be fixed to the first robotic arm 100, a second side frame 140 is fixedly installed on one side of the first robotic arm 100, and a support rod 1401 is provided on the second side frame 140; when the hook bend of the first hook plate 320 on the rotating hook assembly 300 hooks onto the support rod 1401 on the second side frame 140 on one side of the first robotic arm 100, it is in the first locking state, and at this time the walking switching frame 200 is fixed to the first robotic arm 100; at this time, when the second robotic arm 110 can be driven to extend, the walking switching frame 200 slides on the surface of the second robotic arm 110.

[0020] like Figure 3 As shown, when the hook assembly 300 needs to be fixed to the second robotic arm 110, an end head 120 is fixedly installed at one end of the second robotic arm 110. The end head 120 has a mounting part, which is used to install a hook. A first side frame 130 is fixedly installed on one outer wall of the end head 120. The first side frame 130 has a frame opening 1301. A rod is located at the frame opening 1301. When the hook bend of the second hook plate 330 on the hook assembly 300 hooks onto the rod of the frame opening 1301, it is in the second locking state. At this time, the travel switching frame 200 is fixed to the second robotic arm 110. At this time, when the second robotic arm 110 is extended, the digging assembly 500 can be adjusted for extension.

[0021] like Figure 4 and Figure 5 As shown, the elastic connection component 400 is set inside the walking switch frame 200. The elastic connection component 400 is elastically connected to the rotating hook component 300, which makes it easy for the rotating hook component 300 to return to its original position. The elastic connection assembly 400 includes: a first mounting block 410, a second mounting block 420, and a tension spring 430; the first mounting block 410 is fixedly mounted on the outer side wall of the second hook plate 330, and the first mounting block 410 has a round opening; the second mounting block 420 is fixedly mounted on the outer side wall of the inner wall of the walking switching frame 200 corresponding to the wear-resistant pad 210, and the second mounting block 420 has a round opening; the tension spring 430 has hooks at both ends, and the hooks at both ends are respectively hooked between the round openings of the first mounting block 410 and the round openings of the second mounting block 420; when the second hook plate 330 on the rotating cylinder 310 is subjected to force and deflects, it can drive the tension spring 430 to deform and stretch; conversely, when the second hook plate 330 on the rotating cylinder 310 is not subjected to force, the rotating cylinder 310 returns to its original position; When the drilling assembly 500 is not in use and is being recycled, the motor that drives the mounting rod 510 is started, causing the mounting rod 510 to deflect at the bottom of the travel switching frame 200. During the deflection of the mounting rod 510, when the mounting rod 510 deflects and abuts against the roller 360 at the bottom of the hinge plate 350, the hook bend of the first hook plate 320 on the rotating drum 310 can be hooked onto the frame rod 1401 of the second side frame 140 on the outer side wall of the first robotic arm 100. At this time, the travel switching frame 200 is fixed to the first robotic arm 100 through the rotating hook assembly 300, which is the first locked state. When the second robotic arm 110 is driven to extend, the travel switching frame 200 slides on the surface of the second robotic arm 110. At this time, the second robotic arm 110 can drive the end 120 to extend forward, which can realize the lifting operation. When the drilling assembly 500 is in use, the mounting rod 510 disengages from the roller 360 at the bottom of the hinge plate 350. At this time, under the elastic force of the elastic connection assembly 400, the rotating hook assembly 300 returns to its original position. At this time, the hook bend of the second hook plate 330 on the rotating drum 310 hooks onto the frame opening 1301 rod of the first side frame 130 on the outer side wall of the upper end 120 of the first robotic arm 100. At this time, the travel switching frame 200 is fixed to the second robotic arm 110 through the rotating hook assembly 300, which is the second locked state. At this time, when the second robotic arm 110 is extended, the drilling assembly 500 on the bottom side of the travel switching frame 200 can be moved forward to facilitate the drilling operation of the drilling assembly 500.

[0022] In this application, by adjusting the deflection of the mounting rod 510 on the drilling assembly 500, when the hook bend of the first hook plate 320 on the hook assembly 300 hooks onto the support rod 1401 of the second side frame 140 on the outer wall of the first robotic arm 100, the travel switching frame 200 is fixed to the first robotic arm 100 through the hook assembly 300, which is the first locked state. The drilling assembly 500 is not in use and is being retracted. At this time, when the second robotic arm 110 is driven, the end 120 can be extended forward to realize the lifting operation. When the mounting rod 510 disengages from the roller 360 at the bottom of the hinge plate 350, the hook assembly 300 returns to its original position under the elastic force of the elastic connection assembly 400. At this time, the rotating drum 310... The hook bend of the second hook plate 330 hooks onto the frame opening 1301 rod of the first side frame 130 on the outer side wall of the upper end 120 of the first robotic arm 100. At this time, the travel switching frame 200 is fixed to the second robotic arm 110 through the rotating hook assembly 300, which is the second locked state. At this time, when the second robotic arm 110 is extended, the digging assembly 500 on the bottom side of the travel switching frame 200 can be moved forward, which facilitates the digging assembly 500 to perform digging operations. In this application, the rotating hook assembly 300 and the elastic connection assembly 400 can be used to switch between lifting and digging operations of the robotic arm, so that the drilling machine has the function of lifting and digging operations, which improves the practicality of the drilling machine robotic arm.
