[0030] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0031] See also Figure 1 , which is a structural schematic diagram of a dual-motor anchor bolt construction device provided by the utility model. Figures 1 to 13 The dual-motor anchor construction device includes, for example: a mounting seat 10 , a locking portion 20 , a grouting portion 30 , and a telescopic cylinder 40 . Among them, the locking part 20, the grouting part 30, and the telescopic cylinder 40 are arranged on the mounting seat 10; the locking part 20 includes a locker 26 and a locking motor 21, the locking motor 21 drives the connection locker 26, and the locking motor 21 can drive the locker 26 to rotate, so as to lock the grouting locking nut 71 of the grouting anchor 70; the grouting part 30 is used to grout into the grouting anchor 70, the grouting part 30 includes a rotary motor 31 and a grouting shaft 32, the top of the grouting shaft 32 is provided with a grouting port 321, and a grouting channel 322 is provided inside, and the grouting channel 322 is connected to the grouting port 321; wherein, the rotary motor 31 drives the connection grouting shaft 32, and the rotary motor 31 can drive the grouting shaft 32 to rotate, so as to install the grouting shaft 32 to the tail of the grouting anchor 70, and perform the anchor installation operation and grouting operation of the dual-motor anchor construction device. When the grouting operation is completed, the rotary motor 31 is controlled to reverse, and the rotary motor 31 can drive the grouting shaft 32 to reverse, thereby separating the grouting shaft 32 from the tail of the grouting anchor rod 70. For example, the locking portion 20 is a locking box, which is mounted on the mounting seat 10 by bolts.

[0032] It is understandable that the locking part 20 and the grouting part 30 of the dual-motor anchor construction device in the present application are each provided with a driving motor, which can realize the independent rotation of the grouting shaft 32 and the locker 26, and the grouting shaft 32 and the locker 26 do not interfere with each other. When the grouting anchor 70 is locked and grouted, there is no need to repeatedly use the telescopic cylinder 40, which is more convenient to operate.

[0033] Furthermore, the locking portion 20 further includes a locking shaft 25. Among them, a locking device 26 is connected to the end of the locking shaft 25. For example, the locking device 26 is connected to the locking shaft 25 through a non-circular structure. When the locking shaft 25 rotates, the locking shaft 25 can drive the locking device 26 to rotate together, so as to realize the locking operation of the grouting locking nut 71 of the grouting anchor 70 by the dual-motor anchor construction device. For example, the locking device 26 can be connected to the locking shaft 25 through a spline, and can also be connected to the locking shaft 25 through a square structure, which is not limited here.

[0034] Furthermore, the grouting shaft 32 is inserted into the locking shaft 25. When the grouting part 30 slides forward and backward on the mounting seat 10, the grouting shaft 32 slides axially in the locking shaft 25. When the grouting part 30 slides forward on the mounting seat 10, the grouting shaft 32 slides forward in the locking shaft 25; when the grouting part 30 slides backward on the mounting seat 10, the grouting shaft 32 slides backward in the locking shaft 25.

[0035] For example, when the dual-motor anchor construction device performs anchor installation operations and grouting operations, the grouting shaft 32 is located at the front end; when the dual-motor anchor construction device performs nut locking operations, the grouting shaft 32 is located at the rear end.

[0036] Furthermore, the locking portion 20 further includes a transmission assembly which is disposed between the locking shaft 25 and the locking motor 21 and is used to transmit the driving force output by the locking motor 21 to the locking shaft 25 , and then to the locker 26 through the locking shaft 25 .

[0037] Furthermore, the transmission assembly includes: a driving gear 22, a driven gear 23, and a flat key 24. The driving gear 22 is arranged on the output shaft of the locking motor 21, the driving gear 22 and the driven gear 23 are meshed, and a flat key 24 is arranged between the driven gear 23 and the locking shaft 25. Specifically, the locking motor 21 can drive the driving gear 22 to rotate, the driving gear 22 drives the driven gear 23 meshed therewith to rotate, and the driven gear 23 drives the locking shaft 25 to rotate through the flat key 24.

[0038] Furthermore, the front end of the grouting shaft 32 is provided with an anchor connecting thread 33 that matches the tail of the grouting anchor 70. For example, the grouting anchor 70 is an expansion shell anchor, and the anchor connecting thread 33 can be a corrugated thread, a T-thread or other non-standard thread for connecting the expansion shell anchor.

[0039] When the telescopic oil cylinder 40 drives the grouting shaft 32 to slide to the front end, the rotary motor 31 is started, and the grouting shaft 32 can be installed to the tail of the grouting anchor rod 70; after the grouting shaft 32 is installed to the tail of the grouting anchor rod 70, the rotary motor 31 continues to drive the grouting shaft 32 to rotate, and the grouting anchor rod 70 can be driven to rotate together through the grouting shaft 32, so that the grouting anchor rod 70 is fixedly installed in the hole of the tunnel. When the grouting operation is completed, the rotary motor 31 is controlled to reverse, and the grouting shaft 32 can be removed from the tail of the grouting anchor rod 70.

[0040] Furthermore, the telescopic oil cylinder 40 is arranged opposite to the grouting part 30. When the telescopic oil cylinder 40 is extended, the grouting part 30 slides backward; when the telescopic oil cylinder 40 is retracted, the grouting part 30 slides forward. The telescopic oil cylinder 40 is arranged opposite to the grouting part 30, which can reduce the axial length of the dual-motor anchor bolt construction device, making the structure of the dual-motor anchor bolt construction device more compact and the layout more reasonable, avoiding the increase in construction difficulty caused by the excessive length of the dual-motor anchor bolt construction device.

[0041] For example, when the telescopic cylinder 40 is extended, the grouting part 30 slides backward, thereby driving the grouting shaft 32 to slide backward in the locking shaft 25; when the telescopic cylinder 40 is retracted, the grouting part 30 slides forward, thereby driving the grouting shaft 32 to slide forward in the locking shaft 25.

[0042] Furthermore, the dual-motor anchor bolt construction device further includes: a sliding guide portion, which is arranged on the mounting seat 10 along the axial direction of the grouting axis 32, and is used to limit the sliding direction and sliding distance of the grouting portion 30. For example, the dual-motor anchor bolt construction device includes two sliding guide portions, which are respectively arranged on both sides of the grouting portion 30 to guide the sliding of the grouting portion 30 on the mounting seat 10.

[0043] Furthermore, the grouting part 30 also includes a grouting support part. The sliding guide part is a sliding rod 51 passing through the grouting support part, and limit baffles 52 are arranged at both ends of the sliding rod 51. When the telescopic cylinder 40 drives the grouting part 30 to slide, the grouting support part 33 slides along the length direction of the sliding rod 51.

[0044] Furthermore, the dual-motor anchor bolt construction device further includes a protective cover 60. The protective cover 60 is disposed outside the grouting part 30 to protect the grouting part 30. The locking motor 21 is also located in the protective cover 60.

At this time, the grouting shaft 32 drives the grouting anchor bolt 70 to rotate together, and the grouting anchor bolt 70 is fixedly installed in the hole of the tunnel through the expansion head on the grouting anchor bolt 70.

[0048] Locking nut stage: start the locking motor 21, the locking motor 21 drives the driving gear 22 to rotate, the driving gear 22 drives the driven gear 23 meshing therewith to rotate, the driven gear 23 drives the locking shaft 25 to rotate through the flat key 24, the locking shaft 25 drives the locker 26 to rotate, and the grouting locking nut 71 of the grouting anchor rod 70 is locked.
