[0051] See Figure 1 、 Figure 2 As shown in

[0052] See Figure 1 、 Figure 2, the base 1 is used for installing and supporting other components of the picking and delivering device, and should have sufficient strength and stability to ensure its stability under complex stress conditions. Exemplarily, the base 1 can be a frame structure made of steel. The bearing plate 6 can be a horizontally arranged rectangular steel plate, and the bearing plate 6 is arranged above the base 1 and is slidably connected to the base 1, so that the bearing plate 6 can slide horizontally on the base 1. The driving mechanism is connected between the base 1 and the bearing plate 6 and is used for driving the bearing plate 6 to slide horizontally back and forth on the base 1. The clamping assembly is installed above the bearing plate 6 and is used for clamping and fixing the anchor rod. For example, the clamping assembly includes a fixed seat 7, a moving seat 17 and a lifting mechanism. The fixed seat 7 is arranged above the bearing plate 6 and is fixedly connected to the bearing plate 6. The moving seat 17 is arranged above the fixed seat 7 and can move up and down relative to the fixed seat 7. The lifting mechanism is connected between the bearing plate 6 and the moving seat 17 and is used for driving the moving seat 17 to move up and down, so as to clamp and fix the anchor rod between the moving seat 17 and the fixed seat 7.

[0053] See Figure 1 , Figure 2 , the tunnel construction anchor rod picking and delivering device provided by the embodiment of the present application is used for replacing the anchor rod; the specific construction process is as follows: fixedly connect the base 1 with the foundation, place the anchor rod to be replaced on the fixed seat 7, start the lifting mechanism, and the lifting mechanism drives the moving seat 17 to descend and presses the anchor rod against the fixed seat 7 to realize clamping and fixing of the anchor rod; start the driving mechanism, and the driving mechanism drives the bearing plate 6 to move, and the bearing plate 6 drives the clamping assembly and the anchor rod thereon to move, so as to pull out the anchor rod to be replaced from the rock mass.

[0054] When replacing the anchor rod, one anchor rod can be fixed between the moving seat 17 and the fixed seat 7, or two or more anchor rods can be fixed, and no specific limitation is made here. Compared with the existing bolt fixing method, in the present application, the anchor rod is clamped and fixed by the clamping assembly composed of the fixed seat 7, the moving seat 17 and the lifting mechanism, which increases the clamping force on the anchor rod, thereby improving the fixing effect on the anchor rod, effectively preventing the anchor rod from falling off, and improving the safety of the anchor rod during the replacement operation.

[0055] In some embodiments, see Figure 1 , Figure 2 , the moving seat 17 includes at least two, and at least two moving seats 17 are arranged at intervals along the sliding direction of the bearing plate 6. The number of the lifting mechanisms is the same as and corresponds to the number of the moving seats 17 one by one, and the lifting mechanism is used for driving the corresponding moving seat 17 to move up and down. By arranging at least two moving seats 17 and lifting mechanisms, when clamping and fixing the anchor rod, more clamping positions and greater clamping force can be provided, further improving the fixing effect on the anchor rod.

[0056] Exemplarily, see Figure 1 ,Figure 2 There are two moving seats 17, and the two moving seats 17 are arranged at intervals along the sliding direction of the bearing plate 6. There are two lifting mechanisms, and the two lifting mechanisms respectively drive the two moving seats 17 to lift and lower.

[0057] In some embodiments, referring to Figure 2 , Figure 4 , the fixed seat 7 is provided with a bolt pick-up and delivery hole 23 extending along the sliding direction of the bearing plate 6. The bottom of the moving seat 17 is connected with an extension rod 18 extending downward into the bolt pick-up and delivery hole 23, and the lower end of the extension rod 18 is connected with a pressing plate 19. By providing the bolt pick-up and delivery hole 23, it is used to place the bolt in the bolt pick-up and delivery hole 23, providing a protective placement environment for the bolt to avoid possible scratching or collision during the clamping process. By providing the pressing plate 19, when the moving seat 17 moves downward, the moving seat 17 drives the pressing plate 19 to move downward through the extension rod 18, so as to press and fix the bolt at the bottom of the bolt pick-up and delivery hole 23.

[0058] Among them, one, two or more than two bolt pick-up and delivery holes 23 can be provided on the fixed seat 7, and no specific limitation is made here. Exemplarily, referring to Figure 2 , four bolt pick-up and delivery holes 23 are provided on the fixed seat 7 so as to clamp and fix four bolts simultaneously. Among them, the fixed seat 7 can include a fixed pipe fixedly connected to the bearing plate 6, and the inner cavity of the fixed pipe forms the bolt pick-up and delivery hole 23.

[0059] In some embodiments, referring to Figure 2 , an anti-slip pad 8 is provided at the bottom of the bolt pick-up and delivery hole 23. By providing the anti-slip pad 8, not only can the friction between the bolt and the bolt pick-up and delivery hole 23 be increased, further improving the fixing effect of the bolt, but also the bolt is easier to be placed and clamped, improving the construction efficiency.

[0060] The lifting mechanism is used to drive the moving seat 17 to lift and lower. It can include linear drivers such as vertically arranged cylinders, hydraulic cylinders, electric push rods, etc. One end of the linear driver is fixedly connected to the bearing plate 6, and the other end of the linear driver is fixedly connected to the moving seat 17.

The piston rod of the lifting cylinder 10 can be fixedly connected to the top of the moving seat 17. When adopting this design structure, not only does the lifting cylinder 10 serve as a power component to drive the lifting of the moving seat 17, but also the lifting cylinder 10 serves as a guiding component to control the lifting of the moving seat 17 in the vertical direction.

The design of the sliding rod 21 and the slider 20 can guide the lifting of the moving seat 17, ensure the lifting of the moving seat 17 in the vertical direction, and prevent deviation from the predetermined trajectory. Among them, the number of the sliding rods 21 can be one, two or more than two, and no specific limitation is made here; the more the number of the sliding rods 21, the more reliable the guiding of the moving seat 17, but the corresponding cost is higher.

[0064] In some embodiments, referring to Figure 2 , the upper end of the sliding rod 21 is connected to the fixing frame 9, and a return spring 22 located above the slider 20 is sleeved on the sliding rod 21. Exemplarily, the return spring 22 is a compression spring, which is used to always provide a downward return force to the slider 20. When clamping and fixing the anchor rod, the return spring 22 can be used to provide an additional clamping force to further improve the fixing effect of the anchor rod.

The upper connecting rod 13 extends upward and is hinged to the fixing frame 9, and the lower connecting rod 15 extends downward and is hinged to the moving seat 17. During operation, by controlling the extension and contraction of the piston rod of the lifting cylinder 10, under the action of the connecting rod assembly composed of the movable support rod 12, the upper connecting rod 13 and the lower connecting rod 15, the moving seat 17 is driven to lift under the guiding action of the sliding rod 21 and the slider 20.

[0066] Exemplarily, referring to Figure 4, a push block 11 is fixed to the lower end of the piston rod of the lifting cylinder 10.

It can include linear drivers such as horizontally arranged cylinders, hydraulic cylinders, electric push rods, etc. One end of the linear driver is connected to the base 1, and the other end of the linear driver is connected to the bearing plate 6. By the extension and contraction of the linear driver, the bearing plate 6 is driven to slide reciprocally on the base 1. The driving mechanism can also include a motor screw driving mechanism, a motor chain driving mechanism, etc.

[0068] In some embodiments, refer to Figure 3 , the driving mechanism includes a driving cylinder 2 connected to the base 1 and a push plate 3 connected to the piston rod of the driving cylinder 2. The push plate 3 is connected to the bearing plate 6. Among them, the driving cylinder 2 can include a cylinder or a hydraulic cylinder. During operation, by controlling the extension and contraction of the piston rod of the driving cylinder 2, the bearing plate 6 is driven to slide reciprocally in the horizontal direction on the base 1 through the push plate 3. When the push plate 3 and the bearing plate 6 are respectively located on both sides of the base 1, an avoidance chute extending along the sliding direction of the bearing plate 6 is provided on the base 1, and a connecting block for connecting the bearing plate 6 and the push plate 3 is provided in the avoidance chute. Among them, the avoidance chute can include one or two.

[0069] In some embodiments, refer to Figure 3 , a gear 4 is provided on the push plate 3, and a rack plate 5 meshing with the gear 4 is connected to the base 1. The cooperation between the gear 4 and the rack plate 5 can guide the movement of the push plate 3 and improve the reliability of the movement of the push plate 3.

[0070] Exemplarily, both sides of the base 1 have downwardly extending and oppositely arranged side plates. The rack plate 5 is fixed to the inner side of the side plates.
