DETAILED DESCRIPTION

[0026] 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.

[0027] See also Figure 1 , which is a structural schematic diagram of a single motor anchor construction device provided by the present application. Figures 1 to 10The single-motor anchor construction device includes: a mounting seat 10; a locking portion 20, which is arranged at the front end of the mounting seat 10 and is used to lock the grouting locking nut 71 of the grouting anchor 70; a grouting portion 30, which is slidably arranged on the mounting seat 10, including a grouting shaft 31 and a rotary motor 32; a telescopic cylinder 40, which is arranged on the mounting seat 10, and the telescopic cylinder 40 can drive the grouting portion 30 to slide back and forth on the mounting seat 10; wherein, when the grouting portion 30 slides to the locking position, the grouting portion 30 is keyed to the locking portion 20, and the rotary motor 32 can drive the locking portion 20 to rotate through the grouting shaft 31 to lock the grouting locking nut 71 of the grouting anchor 70.

[0028] It can be understood that by providing a key connection structure between the grouting part 30 and the locking part 20, when the grouting part 30 slides to the locking position, the driving force of the rotary motor 32 of the grouting part 30 can be transmitted to the locking part 20 through the key connection structure between the grouting part 30 and the locking part 20, thereby driving the locking part 20 to rotate through the rotary motor 32 of the grouting part 30 to lock the grouting locking nut 71 of the grouting anchor 70, and there is no need to add an additional driving motor to the locking part 20, so that the locking and grouting work of the grouting anchor 70 can be achieved by one motor, thereby reducing the cost of the anchor construction device.

[0029] Furthermore, the locking part 20 includes a locking shaft 21, a locking device 22 and a spline pair 23; the locking device 22 is connected to the front end of the locking shaft 21, and the spline pair 23 is connected to the rear end of the locking shaft 21; the grouting shaft 31 is inserted into the locking shaft 21, and the telescopic oil cylinder 40 can drive the grouting shaft 31 to slide axially in the locking shaft 21. When the telescopic oil cylinder 40 drives the grouting part 30 to slide forward and backward on the mounting seat 10, the grouting shaft 31 slides axially in the locking shaft 21.

[0030] For example, combining Figure 7 and Figure 8 When the grouting shaft 31 slides to the front end, the grouting shaft 31 can be screwed onto the grouting anchor rod 70; when the grouting shaft 31 slides to the rear end, the grouting shaft 31 is in the locking position, and the driving force of the rotary motor 32 can be transmitted to the locker 22 through the grouting shaft 31, driving the locker 22 to lock the grouting locking nut 71 of the grouting anchor rod 70. During the construction process, when the anchor rod is screwed and grouting is in the state, the grouting shaft 31 is located at the front end; when in the locking nut state, the grouting shaft 31 is located at the rear end.

[0031] Furthermore, the front end of the grouting shaft 31 is provided with an internal thread that cooperates with the tail end of the grouting anchor rod 70; when the telescopic cylinder 40 drives the grouting shaft 31 to slide to the front end, the rotary motor 32 is started to screw the front end of the grouting shaft 31 to the tail end of the grouting anchor rod 70.

[0032] Furthermore, when the front end of the grouting shaft 31 is screwed to the tail end of the grouting anchor rod 70 , the rotary motor 32 can drive the grouting anchor rod 70 to rotate through the grouting shaft 31 to fix the grouting anchor rod 70 into the hole of the tunnel.

[0033] Further, the grouting shaft 31 is an external spline shaft. When the telescopic oil cylinder 40 drives the grouting shaft 31 to slide backward to the locking position, the external spline shaft cooperates with the spline pair 23, and the rotary motor 32 can drive the locking part 20 to rotate through the external spline shaft, thereby driving the locker 22 to rotate, so as to lock the grouting locking nut 71 of the grouting anchor 70. For example, the spline pair 23 can be a spline or square structure, and the external spline shaft is connected to the locking part 20 through a spline or square structure to realize the locking nut function.

[0034] 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 single-motor anchor bolt construction device, making the structure of the single-motor anchor bolt construction device more compact and the layout more reasonable, avoiding the small single-motor anchor bolt construction device from being too long and affecting the construction efficiency.

[0035] For example, when the telescopic cylinder 40 is extended, the grouting part 30 slides backward, thereby driving the grouting shaft 31 to slide backward in the locking shaft 21; when the telescopic cylinder 40 is retracted, the grouting part 30 slides forward, thereby driving the grouting shaft 31 to slide forward in the locking shaft 21.

[0036] Furthermore, the single-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 shaft 31, and is used to limit the sliding direction and sliding distance of the grouting portion 30. For example, the single-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.

[0037] Furthermore, the grouting part 30 further includes a grouting support part 33; the sliding guide part is a sliding rod 51 passing through the grouting support part 33, and limit baffles 52 are provided 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.

[0038] Furthermore, a grouting channel 311 is provided in the grouting shaft 31 , and a grouting port 312 is opened on the grouting shaft 31 , and the grouting port 312 is communicated with the grouting channel 311 .

[0039] Furthermore, the single motor anchor bolt construction device further comprises: a protective cover 60. The protective cover 60 is arranged outside the grouting part 30 to protect the grouting part 30.

[0040] In a specific embodiment, the construction steps of the single motor anchor construction device are as follows:

[0041] First, a hole is drilled using a rock drill or other equipment; the telescopic cylinder 40 is retracted to allow the grouting shaft 31 to slide axially in the locking shaft 21, and when the grouting shaft 31 slides forward to the front end, the front end of the grouting shaft 31 hits the grouting anchor 70; the rotary motor 32 is started, and the rotary motor 32 drives the grouting shaft 31 to rotate, and the front end of the grouting shaft 31 is screwed to the tail of the grouting anchor 70, and then the rotary motor 32 continues to rotate, and the grouting shaft 31 drives the grouting anchor 70 to rotate, and the grouting anchor 70 is fastened to the hole in the tunnel through the expansion head on the grouting anchor 70.

[0042] The rotary motor 32 is reversed, so that the front end of the grouting shaft 31 is disengaged from the tail of the grouting anchor 70, and the telescopic cylinder 40 is extended, so that the grouting shaft 31 slides axially in the locking shaft 21. When the grouting shaft 31 slides backward to the locking position at the rear end, the key connection structure between the grouting part 30 and the locking part 20 is utilized to transmit the driving force of the rotary motor 32 of the grouting part 30 to the locking part 20 through the key connection structure, thereby driving the locking device 22 to rotate through the rotary motor 32 of the grouting part 30 to lock the grouting locking nut 71 of the grouting anchor 70.

[0043] The locker 22 and the grouting anchor 70 are disengaged, and the telescopic cylinder 40 is retracted again to drive the grouting shaft 31 to slide forward to the front end, and the rotary motor 32 is started. The rotary motor 32 drives the grouting shaft 31 to rotate, and the front end of the grouting shaft 31 is screwed to the tail of the grouting anchor 70, and then cement slurry is injected into the grouting channel 311 of the grouting shaft 31 through the grouting port 312 until the cement slurry flows out of the orifice.

[0044] The rotary motor 32 is reversed to disengage the front end of the grouting shaft 31 from the rear end of the grouting anchor rod 70. Thus, the installation and grouting operation of the grouting anchor rod 70 is completed, and the next working cycle begins.
