Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction storage, in particular to a splicing storage device for tunnel grouting anchor rods. Background Art

[0002] Grouting anchor is a new product developed according to the actual needs of my country's tunnel engineering, slope control engineering, coal mine tunnel engineering, etc. The main products are: ordinary hollow grouting anchor; self-propelled hollow grouting anchor; shell expansion hollow grouting anchor; combined hollow grouting anchor.

[0003] The anchor body of the grouting anchor adopts a hollow design. The hole in the rod body is used as a high-pressure drilling channel and a grouting channel. Compared with a solid rod body, the hollow rod body design can obtain better rigidity and shear strength. The outer surface of the anchor body has a full-length standard large-pitch thread structure. The thread structure is convenient for cutting and lengthening the anchor. Compared with a smooth rod body, it increases the bonding area between the anchor body and the grouting material, thereby improving the anchoring force.

[0004] During on-site construction, grouting anchor rods are piled on the tunnel floor in a disorderly manner. When selecting grouting anchor rods, staff are required to check them one by one. This stacking method, coupled with the staff using excessive force when extracting them, causes the grouting anchor rods to collide and rub against each other, which may cause deformation and wear, and is not conducive to their later use.

[0005] Chinese patent 202322927049.9 discloses "A storage device for grouting anchor rods in tunnel anchor construction", announcement number CN221074309 U, which includes a mounting block, a horizontal storage box is connected to the top of the mounting block by welding, a take-out plate is provided in front of the horizontal storage box, a fixing plate is provided above the take-out plate, a fixing screw is provided above the fixing plate, and a movable screw is provided behind the fixing screw, a universal wheel is connected to the bottom of the mounting block by welding, a vertical storage box is connected to the rear of the horizontal storage box by welding, a placement hole is penetrated above the vertical storage box, and placement holes of different sizes are penetrated on the vertical storage box, a support column is connected to the right side of the horizontal storage box by welding, a handle is connected to the right side of the support column by welding, and a storage port is penetrated on the left side of the horizontal storage box. However, the device has some defects: the adaptability of the device is low, and it can only be used for grouting anchor rods that meet its height; when the height of the grouting anchor rod is smaller than the storage box of the device, the grouting anchor rod sinks into the placement hole, making it inconvenient to take out; when the length of the grouting anchor rod is larger than the storage box, the grouting anchor rod cannot fully enter, and cannot play the role of isolating water droplets and sealing. Utility Model Content

[0006] In order to solve the above problems of the prior art, the utility model provides a splicing storage device for tunnel grouting anchor rods, which can be suitable for grouting anchor rods of different lengths and models.

[0008] With the above structural design, multiple partitions are engaged up and down to form a space for storing the grouting anchor rods. According to the diameter of the grouting anchor rods, the size of the space is adjusted to be suitable for grouting anchor rods of different diameters.

[0009] Preferably, a plurality of through holes are provided on the supporting plate, and the through holes are truncated cone-shaped.

[0010] The above structural design can prevent water drops dripping from the tunnel from accumulating on the bearing plate, and prevent water on the grouting anchor rods from accumulating on the bearing plate after the grouting anchor rods are cleaned.

[0011] Preferably, a mounting block is fixedly connected to the bearing plate, a ground nail is passed through the mounting block, and a rotating hand wheel is fixedly connected to the ground nail.

[0012] By adopting the above structural design, the device is fixed on the ground to prevent the device from tipping over under the action of external force, thereby preventing the grouting anchor rods from scattering.

[0013] Preferably, the support rod includes a first connecting rod connected to the supporting plate by a thread, and a second connecting rod connected to the first connecting rod, the lower end of the second connecting rod is fixedly connected to the threaded rod, and the upper ends of the first connecting rod and the second connecting rod are provided with threaded holes matching the threaded rod; baffles are mounted on the first connecting rod and the second connecting rod, and nuts are mounted on the first connecting rod and the second connecting rod through threads.

[0014] With the above structural design, when the grouting anchor rod is too long and difficult to be pulled upward in the tunnel, the device can be lengthened and raised, placed horizontally, and used horizontally; the baffle and the nut can prevent the partition from moving in the horizontal direction, thereby preventing the partition from separating under the action of external force.

[0015] Preferably, the positioning plate and the carrying plate are both fixedly connected to universal wheels.

[0016] By adopting the above structural design, the device can be moved both vertically and horizontally.
