Description

Technical Field

[0001] The utility model relates to the technical field of mine supports, in particular to an anchor tray with high compressive strength. Background Art

[0002] During mining, anchor trays, as key components of the support system, work in conjunction with anchors and anchor caps and are crucial to ensuring mine safety. Pressing against the mine tunnel or mountain surface, the trays effectively transmit the thrust generated by the nut tightening torque and withstand the pressure from the tunnel roof, dispersing and transmitting force. This strengthens the surrounding rock, prevents tunnel displacement, and maintains overall mine stability.

[0003] However, some anchor trays currently on the market are not strong enough in compression and may deform or break under harsh conditions, resulting in support failure and posing a serious threat to the lives of miners and safe production in mines.

[0004] Therefore, those skilled in the art are in urgent need of an anchor tray with high compressive strength to improve the support effect and provide strong guarantee for the sustainable development of mines. Utility Model Content

[0005] The main purpose of the utility model is to provide an anchor tray with high compressive strength, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A high compressive strength anchor tray comprises a tray body, on which a conical boosting platform is punched, and the boosting platform has several groups of boosting units evenly arranged along the circumference. The boosting units comprise arc-shaped ribs and grooves adjacent to the ribs. Both the ribs and the grooves are of progressive structure, and their widths gradually increase from top to bottom.

[0008] In a possible implementation, the number of groups of the boosting units is three, four, five, six, or eight.

[0009] In a possible implementation, the number of groups of the boosting units is specifically eight.

[0010] In a possible implementation, the protrusion height of the boost unit is H, and 20 mm ≤ H ≤ 90 mm.

[0011] In a possible implementation, an anchor hole is opened on the top of the boosting platform, the hole diameter of the anchor hole ranges from 20 to 70 mm, and the center line of the anchor hole coincides with the center line of the boosting platform.

[0012] In a possible implementation, a center line of the boosting platform coincides with a center line of the tray.

[0013] In a possible implementation, the disc is circular or square.

[0014] In a possible implementation, the disk is circular, and its diameter is specifically 300 cm.

[0015] In a possible implementation, the disk is square, and its length and width are both 300 cm.

[0016] In a possible implementation, the disc body is provided with a lifting lug or a lifting hole to prevent it from falling.

[0017] Compared with existing technologies, the anchor tray of this utility model effectively solves the problem of support failure caused by insufficient compressive strength, significantly reduces the risk of safety accidents caused by tray damage, and provides stronger protection for the lives of miners. At the same time, the design of the booster platform also optimizes the force transmission path between the anchor and the tray, making the support system more efficient and stable, extending the service life of the support structure, reducing maintenance and replacement costs, and bringing significant economic benefits to the sustainable development of mines.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. In addition, for the convenience of description below, the "upper", "lower", "left", and "right" quoted are the same as the upper, lower, left, and right directions of the drawings themselves. The "first", "second", etc. in the following are distinguished for the description and have no other special meanings.

[0028] In response to the problems existing in the prior art, the utility model provides an anchor tray with high compressive strength, including a tray body, on which a conical boosting platform is punched, and the boosting platform has several groups of boosting units evenly arranged along the circumference. The boosting units include arc-shaped ribs and grooves adjacent to the ribs. Both the ribs and the grooves are progressive structures, and their width gradually increases from top to bottom.

[0029] In specific application scenarios, the booster platform adopts a conical structure with a narrow top and gradually widening bottom, which optimizes the force transmission path between the anchor rod and the pallet. When the pallet is subjected to pressure from the top of the tunnel, the booster platform can effectively disperse the pressure and transmit it to various parts of the pallet, thereby avoiding damage or deformation of the pallet due to concentrated pressure.

[0030] Furthermore, the boosting units are evenly arranged on the boosting platform, thereby forming multiple strengthening points.

[0031] Each pressurizing unit is composed of progressive ribs and grooves. The curved ribs evenly distribute pressure when the pallet is under pressure, preventing damage caused by localized excessive stress. The grooves adjacent to the ribs further disperse the pressure, distributing it to the surrounding area when the pallet is under pressure, further reducing the risk of damage. Furthermore, the grooves increase the contact area between the pallet and the anchor rod, thereby enhancing the anchoring force.

[0032] In some examples, the number of groups of boosting units is three, four, five, six, or eight, and the number of groups of boosting units is specifically eight;

[0033] The protrusion height of the boost unit is H, and 20mm≤H≤90mm.

[0034] In specific application scenarios, the pallet's pressure-bearing performance can be further optimized by properly setting the number of booster units and adjusting the height of the booster units. For example, when there are more booster units and they are shorter, the pallet can withstand greater pressure without deformation or damage.

[0035] In addition, while ensuring that the working performance of the anchor tray is not affected, technical personnel in this field can select the number and height of the booster units according to actual needs. Changes in the number and height of the booster units do not affect the scope of protection of this application.

[0036] In some examples, an anchor hole is opened on the top of the boosting platform, the aperture of the anchor hole ranges from 20 to 70 mm, the center line of the anchor hole coincides with the center line of the boosting platform, and the center line of the boosting platform coincides with the center line of the disk body.

[0037] In specific application scenarios, anchor holes on the top of the booster platform are used to connect and secure anchor rods. The anchor hole diameters are flexible, ranging from 20mm to 70mm, accommodating anchor rods of varying sizes and types, ensuring installation compatibility and flexibility. Crucially, the centerline of the anchor hole aligns with the centerline of the booster platform, and thus with the centerline of the entire tray. This not only enhances the symmetry of the tray structure but also strengthens the overall stability of the support system.

[0038] In some examples, the disc is circular, or square;

[0039] When the disc body is circular, its diameter is specifically 300 cm.

[0040] When the dish body is square, its length and width are both 300 cm.

[0041] In specific application scenarios, the circular disc structure is stable, can evenly disperse pressure, reduce stress concentration, and improve overall stability; under the same circumference, it has the largest volume and larger loading space; it has no sharp edges and corners, is safe and easy to use, and is especially suitable for frequently moved environments; the surface is smooth and uniform in shape, making it easy to stack and store, saving space.

[0042] The square plate has outstanding load-bearing capacity and can demonstrate better load-bearing performance even though its size is similar to that of a round plate. The regular shape and right-angled edges facilitate precise positioning and fixation, making it suitable for precise installation scenarios.

[0043] In addition, while ensuring that the working performance of the anchor tray is not affected, technical personnel in this field can select the shape and size of the tray body according to actual needs. Changes in the shape and size of the tray body do not affect the scope of protection of this application.

[0044] Furthermore, the disc's stepped shape significantly enhances its performance. By varying the disc's cross-sectional shape, the stepped design allows pressure to be gradually transferred and dispersed along the stepped surfaces, reducing local stress levels within the disc, thereby extending its service life and minimizing the risk of damage. Furthermore, the stepped shape enhances its load-bearing capacity.

[0045] Furthermore, the outer surface of the pallet is electroplated with a galvanized layer, which effectively enhances the pallet's anti-corrosion performance, extends its service life and reduces maintenance costs.

[0046] In some examples, the disc body is provided with a lifting lug or a lifting hole to prevent it from falling.

[0047] In specific application scenarios, the lifting ears or lifting holes provide a stable anti-falling measure for the pallet. They can be firmly fixed to the steel mesh on the bottom and wall of the well, ensuring that the pallet remains stable when facing sudden pressure in the tunnel, effectively preventing it from falling and avoiding possible personal injury.

Both the ribs 211 and the grooves 212 are progressive structures, and their widths gradually increase from top to bottom.

[0050] In the example, Figure 2 As shown, the number of groups of boosting units 21 is specifically eight.

[0051] In the example, Figure 1 As shown, the protrusion height H of the boosting unit 21 is 60 mm.

[0052] In the example, Figure 3 As shown, an anchor hole 22 is opened on the top of the boosting platform 2. The aperture range of the anchor hole 22 is 25 mm, and the center line of the anchor hole 22 coincides with the center line of the boosting platform 2.
