[0007] In some embodiments, the quick-connector includes a first link, a second link, and a third link. One end of the first link is hinged to the end of the stick, one end of the second link is hinged to the other end of the first link, the other end of the second link and one end of the third link are hinged to the telescopic end of the attachment cylinder, and the other end of the third link is hinged to the stick. The first link, the second link, the third link, and the stick form a four-bar linkage.

[0008] In some embodiments, the first connecting rod has multiple connecting slots, and both the auger attachment and the gripper attachment are provided with multiple connecting pins, which are connected to the connecting slots by a ring clamp.

[0009] In some embodiments, the auger attachment includes: Spiral drill main unit; A double-pin bracket is used to connect with the quick connector and is equipped with an arc plate, the arc plate being matched with the diameter of the auger main unit; The connecting rod rotatably connects the double-pin bracket to the auger drill main unit.

[0010] In some embodiments, the double-pin bracket includes: The bracket part includes two bracket side plates, a base plate connecting the long sides of the two bracket side plates, and a bracket end plate connecting the short sides of the same end of the two bracket side plates. The two bracket side plates are provided with bracket pin holes aligned with each other, and the arc plate connects the short sides of the other end of the two bracket side plates. The ear plate is connected to the bracket end plate.

[0011] In some embodiments, the connecting rod has a first pin hole and a second pin hole, the axis of the first pin hole and the axis of the second pin hole are perpendicular to each other, the first pin hole is used to connect with the pin of the double pin bracket, and the second pin hole is used to connect with the pin of the auger drill main unit.

[0019] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0020] The terminology of the integrated work vehicle 100 according to this application is described below with reference to the accompanying drawings.

[0021] like Figures 1 to 3 As shown, a specific embodiment of this application provides a comprehensive work vehicle 100, including a chassis 10, a boom 8, and a stick 6 that are articulated sequentially. The comprehensive work vehicle 100 also includes an auger attachment 3, a grab attachment 2, a quick connector 4, and an attachment hydraulic system 5. The auger attachment 3 is used for drilling operations, and the grab attachment 2 is used for pole erection operations. The quick connector 4 is connected to the end of the stick 6 and is used to connect one of the auger attachment 3 and the grab attachment 2. The attachment hydraulic system 5 includes an auger attachment 3 quick-change connector and an auger attachment hydraulic circuit 52 that are connected to each other, and a grab attachment 2 quick-change connector and a grab attachment hydraulic circuit 51 that are connected to each other. The auger attachment 3 quick-change connector is used to connect to the auger attachment 3, and the grab attachment 2 quick-change connector is used to connect to the auger attachment 3.

[0022] The integrated power distribution vehicle 100 is used for power distribution network construction, which includes drilling and pole erection. Drilling is performed using an auger attachment 3, and pole erection is performed using a pole gripper attachment 2. In this application, the integrated power distribution vehicle 100 connects one of the auger attachment 3 and the pole gripper attachment 2 via a quick connector 4 to enable function switching. This allows a single integrated power distribution vehicle 100 to independently complete both drilling and pole erection, thereby reducing construction costs. After drilling, the auger attachment 3 can be disconnected from the quick connector 4, and the pole gripper attachment 2 can be reconnected to the quick connector 4 for pole erection, resulting in a faster switching speed and improved construction efficiency.

[0023] In a specific embodiment of this application, the work arm includes a chassis 10, a boom 8, a stick 6, and a quick connector 4, which are sequentially hinged. A boom cylinder 9 is installed on the boom 8 to drive the boom 8 to rotate relative to the chassis 10. A stick cylinder 7 is installed on the stick 6 to drive the stick 6 to rotate relative to the boom 8. An attachment cylinder 11 is installed on the stick 6 to drive the quick connector 4 to rotate relative to the stick 6. The posture adjustment of the work arm is completed by the boom cylinder 9, the stick cylinder 7, and the attachment cylinder 11. At the same time, the posture adjustment of the attachment connected to the quick connector 4 is completed by the attachment hydraulic system 5, thereby completing the drilling operation and the pole erection operation.

[0024] Furthermore, the posture adjustment of the quick connector 4 is achieved by extending and retracting the attachment cylinder 11, so as to facilitate the installation and removal of the attachment.

[0025] like Figure 4 As shown, in some embodiments, the quick connector 4 includes a first link 41, a second link 42, and a third link 43. One end of the first link 41 is hinged to the end of the boom 6, one end of the second link 42 is hinged to the other end of the first link 41, the other end of the second link 42 and one end of the third link 43 are hinged to the telescopic end of the attachment cylinder 11, and the other end of the third link 43 is hinged to the boom 6. The first link 41, the second link 42, the third link 43, and the boom 6 form a four-bar linkage. The four-bar linkage has the characteristic of structural stability, which strengthens the structural strength of the quick connector 4, thereby improving the connection stability between the attachment and the quick connector 4.

[0026] In some embodiments, the first connecting rod 41 has multiple connecting slots 44, and both the auger attachment 3 and the gripper attachment 2 are provided with multiple connecting pins. The connecting pins are connected to the connecting slots 44 by a ring clamp. The ring clamp strengthens the connection between the connecting pins and the connecting slots 44, thereby enhancing the connection strength between the quick connector 4 and the attachment and improving the connection stability between the attachment and the quick connector 4.

[0027] Furthermore, the connecting pin and connecting slot 44 can be separated simply by removing the ring clamp, thereby speeding up the assembly and disassembly of the attachments and further improving the construction efficiency of the integrated work vehicle 100.

[0028] like Figures 5 to 7 As shown, in some embodiments, the auger attachment 3 includes an auger main body 31, a double pin bracket 32 ​​and a connecting rod 33. The double pin bracket 32 ​​is used to connect with the quick connector 4 and is equipped with an arc plate 34. The arc plate 34 matches the diameter of the auger main body 31. The connecting rod 33 rotatably connects the double pin bracket 32 ​​and the auger main body 31.

[0029] Specifically, the double pin bracket 32 ​​is connected to the first connecting rod 41, and the connecting rod 33 rotatably connects the double pin bracket 32 ​​to the auger drill host 31. The double pin bracket 32 ​​can be driven to rotate by the extension and retraction of the attachment cylinder 11. When the drilling depth is deep and the verticality requirement is high, the double pin bracket 32 ​​can be rotated so that the arc plate 34 on the double pin bracket 32 ​​is tightly fitted with the auger drill host 31 to prevent the auger drill host 31 from swinging, thereby effectively controlling the verticality of the base hole.

[0030] Furthermore, the first link 41 is made of high-strength alloy steel, which has high strength to enhance the structural strength of the quick connector 4, thereby improving the connection stability between the attachment and the quick connector 4.

[0031] In some embodiments, the double pin bracket 32 ​​includes a bracket portion 321 and an ear plate portion 322. The bracket portion 321 includes two bracket side plates, a bracket base plate connecting the long sides of the two bracket side plates, and a bracket end plate connecting the short sides of the same end of the two bracket side plates. The two bracket side plates are aligned and have bracket pin holes. An arc plate 34 connects the short sides of the other end of the two bracket side plates. The ear plate portion 322 is connected to the bracket end plate, and a connecting pin passes through the ear plate hole on the ear plate portion 322.

[0032] Specifically, the bracket portion 321 has a groove-shaped structure to accommodate the end of the auger main unit 31, so that the arc plate 34 mounted on the bracket portion 321 can contact the end of the auger main unit 31.

[0033] Furthermore, the arc plate 34 is detachably connected to the bracket part 321. Since the auger attachment 3 needs to be replaced with different sizes of auger main unit 31 according to different rods 1, the adaptability of the auger attachment 3 can be improved by replacing different arc plates 34 to adapt to different sizes of auger main unit 31.

[0034] In some embodiments, the connecting rod 33 has a first pin hole and a second pin hole. The axis of the first pin hole is perpendicular to the axis of the second pin hole. The first pin hole is used to connect with the pin of the double pin bracket 32, and the second pin hole is used to connect with the pin of the auger drill host 31. The first pin hole and the second pin hole, whose axes are perpendicular to each other, allow the auger drill host 31 to swing laterally and longitudinally relative to the double pin bracket 32, thereby adjusting and counteracting the radial load during drilling and thus preventing damage to the auger drill attachment 3.

[0035] In some embodiments, a rubber gasket is installed on the arc plate 34 to reduce wear on the arc plate 34, and the service life of the arc plate 34 can be extended by replacing the rubber gasket.

[0036] like Figure 8 and Figure 9As shown, in some embodiments, the gripper attachment 2 includes a clamping mechanism 21, a limiting device 22, a dual-axis tilt sensor 23, a rotary drive 24, a horse head 25, an opening and closing cylinder 26, and a synchronous connecting rod 27. The clamping mechanism 21 is driven to open and close by the opening and closing cylinder 26, and the synchronous connecting rod 27 enables the clamping mechanism 21 to open and close synchronously. The rotary drive 24 can rotate 360° and is mainly used to adjust the angle of the gripper attachment 2, which can adjust the gripped rod 1 to a vertical state. The limiting device 22 can be adjusted to meet the limiting clamping of rods 1 with different diameters.

[0037] like Figure 10 As shown, in some embodiments, the integrated work vehicle 100 also includes a bucket attachment 12, and a quick connector 4 for connecting one of the bucket attachment 12, the auger attachment 3, and the grab bar attachment 2. Some sites require site leveling and excavation before drilling operations. Adding the bucket attachment 12 further enhances the functionality of the integrated work vehicle 100, thereby further reducing construction costs and improving construction efficiency.
