Description

Technical Field

[0001] This utility model relates to the technical field of mine equipment storage devices, specifically to an anchor bolt tray storage device. Background Technology

[0002] In mine roadway support operations, anchor bolt trays, as consumables, need to be stored in large quantities underground. The current common practice is to stack the trays directly on the roadway floor or simple mats, causing them to be in constant contact with water and coal slurry, accelerating corrosion and making the edges prone to warping and deformation. This not only wastes materials, but deformed trays can also lead to support failure. Furthermore, haphazardly stacked trays obstruct already narrow working passageways, posing a tripping hazard and, in emergencies, potentially blocking safe escape routes.

[0003] To improve storage standardization, some mines use fixed storage racks. A typical structure consists of multiple round steel columns vertically welded to a rigid base, with pallets fitted onto the columns through a central hole for vertical storage. However, this type of device has a fundamental limitation: the column positions and spacing are fixed by welding, and it can only accommodate a single size of anchor bolt pallet. In reality, various sizes of anchor bolt pallets are needed underground to meet different support scenarios, meaning different sizes of anchor bolt pallets cannot share the same storage rack. This forces mines to repeatedly configure multiple sets of storage equipment, significantly increasing costs and management burden.

[0004] While existing storage technologies have solved the problem of messy stacking, poor sizing adaptability due to structural rigidity has become a new bottleneck. Therefore, there is an urgent need for a storage device that can flexibly adapt to anchor bolt trays of different sizes to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an anchor bolt tray storage device that can centrally store anchor bolt trays of different specifications.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An anchor bolt tray storage device includes: a base, several positioning rods and a sliding limiting assembly, wherein the positioning rods are slidably connected to the base through the sliding limiting assembly, and the outer diameter of the positioning rods is adapted to the inner diameter of the anchor bolt tray.

[0008] Furthermore, the sliding limiting component includes a T-shaped slide groove and a T-shaped slider adapted to the T-shaped slide groove. The T-shaped slide groove is formed in the base, and the T-shaped slider is fixed to one end of the positioning rod.

[0009] Furthermore, the sliding limiting assembly also includes multiple annular limiting grooves and multiple positioning bushings; the multiple annular limiting grooves are evenly opened on the upper surface of the base and are located directly above the T-shaped sliding groove; one positioning bushing is slidably sleeved on one positioning rod, and the inner diameter of the positioning bushing is adapted to the outer diameter of the positioning rod; the inner diameter of the annular limiting groove is adapted to the outer diameter of the positioning bushing.

[0010] Furthermore, grooves are provided on both the left and right sides of the upper surface of the positioning bushing, and lifting pins are embedded in the grooves. The top of the lifting pins is flush with or lower than the upper surface of the positioning bushing.

[0011] Furthermore, a nut rod is provided on one side of the base, and the outer diameter of the nut rod is adapted to the inner diameter of the nut of the anchor tray.

[0012] Furthermore, the base is equipped with casters at the bottom and towing hooks at both ends.

[0013] Furthermore, the positioning rod is provided with a scale.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model provides a flexible and stable sliding adjustment basis for the positioning rod through a sliding assembly consisting of a T-shaped groove and a T-shaped slider set on the base. This design allows the positioning rod to be precisely adjusted according to the different specifications of the anchor rod trays to be stored. Whether facing trays with different inner diameters or outer diameters, the spacing can be freely changed by sliding the positioning rod, thereby adapting to the storage needs of anchor rod trays of various specifications. This effectively solves the problem that traditional fixed brackets cannot be compatible with multiple specifications of workpieces, and greatly improves the adaptability of the device to different working scenarios.

[0016] 2. This utility model utilizes a limiting component consisting of an annular groove on the base and a positioning sleeve integrated on the slider to achieve rigid locking after the positioning rod is adjusted to the target position. This locking method not only ensures the stability of the positioning rod during storage and transportation, preventing displacement due to vibration, bumps, etc., and ensuring the safety of the anchor rod tray, but also makes operation more convenient with the lifting pin design on the positioning sleeve. Operators can easily pull the positioning sleeve by lifting the pin to quickly release the locked state. More importantly, during the sliding adjustment of the positioning rod, there is no need to remove the positioning sleeve from the positioning rod, reducing operation steps and significantly improving work efficiency.

[0022] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0023] Example 1

[0024] This embodiment discloses an anchor bolt tray storage device, which includes a base 10, several positioning rods 20, and a sliding limiting assembly. The outer diameter of the positioning rods 20 is adapted to the inner diameter of the anchor bolt tray, which can stably fix the anchor bolt tray and prevent it from tipping over when stacked. Moreover, the positioning rods 20 are slidably connected to the base 10 through the sliding limiting assembly, which can flexibly adjust the spacing to adapt to anchor bolt trays of different specifications. This solves the problem that traditional fixed supports cannot be compatible with multiple specifications of workpieces, and is especially suitable for the tray storage and retrieval needs in various support scenarios in mines.

[0025] The sliding limit assembly, as a key structure for enabling flexible adjustment and locking of the positioning rod 20, consists of a T-shaped slide groove 31, a T-shaped slider 32, an annular limiting groove 33, and a positioning bushing 34. The T-shaped slide groove 31 is embedded inside the base 10, and the T-shaped slider 32 is welded to the bottom of the positioning rod 20. The sliding cooperation between the two allows the positioning rod 20 to move smoothly along the axial direction of the slide groove.

[0026] Considering the unique environment of mine roadways, with its rugged terrain and frequent severe jolting during transport due to roadway undulations and equipment start-ups and shutdowns, the positioning rod is highly susceptible to displacement under these vibrations if it lacks a stable fixation after adjustment. Displacement of the positioning rod can lead to imbalance in the stacking of the anchor bolt trays, potentially causing them to tip over, impacting work efficiency and posing safety hazards. Therefore, reliable limiting components are essential to ensure the positioning rod is firmly fixed to the base. In this embodiment, multiple annular limiting grooves 33 are evenly distributed on the upper surface of the base 10, directly above the T-shaped groove 31. The positioning sleeve 34 can slide onto the positioning rod 20 (its inner diameter matches the outer diameter of the positioning rod 20), and its outer diameter matches the inner diameter of the annular limiting groove 33. Once the positioning rod 20 is adjusted to the appropriate position, sliding the positioning sleeve 34 into the corresponding annular limiting groove 33 locks it in place, effectively preventing displacement of the positioning rod 20 during transport or jolting, ensuring the tray remains stable even in complex mine roadway conditions.

[0027] To further enhance ease of operation, grooves for built-in lifting pins 35 are provided on both sides of the upper surface of the positioning sleeve 34. The top of the lifting pin 35 is flush with or lower than the upper surface of the positioning sleeve 34. When the operator needs to slide the positioning rod 20, there is no need to remove the positioning sleeve 34. Simply lift the positioning sleeve 34 with the lifting pin 35 to release the lock, which is suitable for quick adjustment in the narrow space of the mine.

[0028] The base 10 is also equipped with a nut rod 40 on one side. Its outer diameter is precisely matched with the inner diameter of the nut that matches the anchor tray. It can centrally store nut accessories, avoiding the problem of nuts being separated from the tray and lost in traditional storage, and ensuring that the nut can be quickly matched and installed when the tray is taken out.

[0029] As an optimized design, the base 10 is equipped with casters 50 at the bottom and traction hooks 60 at both ends, allowing the device to move flexibly in mine roadways. It can be easily retrieved and used with the help of traction equipment or manual dragging, eliminating the need for a fixed storage point and significantly improving on-site operation efficiency. The positioning rod 20 has added scale markings on its surface, which can intuitively count the number of pallets, facilitating inventory management and requisition registration.

[0030] Its specific working principle is as follows:

[0031] When storing anchor bolt trays, the operator first lifts the positioning sleeve 34 using the lifting pin 35 according to the specifications and dimensions of the tray to be stored. This disengages the positioning sleeve 34 from the annular limiting groove, releasing the locking of the positioning rod 20. Then, the positioning rod 20 is pushed, and the sliding characteristics of the T-shaped slider 32 within the T-shaped groove 31 are used to adjust the spacing between multiple positioning rods 20 to match anchor bolt trays of different specifications. After adjustment, the positioning sleeve 34 is allowed to fall naturally and embed into the corresponding annular limiting groove 33. At this point, the cooperation between the positioning sleeve 34 and the annular limiting groove 33 secures the positioning rod 20, preventing displacement during subsequent operations. Next, the anchor bolt trays are placed one by one onto the positioning rods 20. The compatibility between the positioning rods 20 and the inner hole of the tray ensures stable storage. Simultaneously, the tray's matching nut can be fitted onto the nut rod 40 for centralized management of accessories. During transportation, the casters 50 at the bottom of the base 10 facilitate movement of the device within mine roadways, while the towing hooks 60 on both sides can be connected to towing equipment or manually pulled, ensuring the device can flexibly reach the work point. When a pallet needs to be retrieved, it can be directly removed from the positioning rod 20. The markings on the positioning rod 20 help operators quickly count the remaining quantity. If a different size pallet needs to be replaced, the above operation of adjusting the spacing of the positioning rods 20 can be repeated. The entire process does not require disassembly of any parts, greatly improving work efficiency.

[0032] In summary, this utility model, through the design of a sliding and adjustable positioning rod 20, a matching sliding limit component, a dedicated nut storage structure, and a movable base 10, achieves centralized, stable storage and flexible transfer of anchor bolt trays and matching nuts of different specifications. It has the advantages of strong adaptability, convenient operation, safe transportation, and efficient management, and can effectively meet the on-site use needs in complex operating environments such as mines.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
