Abstract
Description
Technical Field
[0001] The utility model relates to the field of supporting tools, in particular to an anchor tray used for tunnel construction and underground mine mining support. Background Art
[0002] In the process of tunnel construction and underground mining, the instability of rock mass is one of the main reasons for accidents and delays in project progress. In order to ensure the safety of workers and the smooth progress of the project, effective support measures must be taken. Anchor tray is a commonly used component that uses the supporting force of the tray to strengthen the anchoring force of the anchor.
[0003] However, traditional anchor pallets have some significant drawbacks. First, they have low support and low strength, which results in insufficient support capacity when facing large-scale or high-pressure rock masses, and cannot effectively prevent rock collapse or slippage. Second, anchor pallets are prone to rust, especially in humid underground environments, which can weaken the support and durability of the pallets, thereby affecting their long-term stability. In addition, the low elasticity of traditional anchor pallets means that they cannot effectively adapt to uneven rock surfaces and cannot provide uniform support, which has serious limitations in irregular underground environments. Utility Model Content
[0004] The utility model provides a rolled-edge anchor tray, and its purpose is to provide a new anchor tray which has a stable structure, strong supporting force, a water-draining function and is more suitable for uneven rock bodies.
[0005] The technical solution of this utility model is as follows:
[0006] A rolled edge anchor tray comprises a tray body, an anchor hole (3) is provided at the center of the tray body, a bowl-shaped protrusion (1) is provided in the tray body, the anchor hole (3) is opened at the top of the bowl-shaped protrusion (1), a first rolled edge (2) is provided at the anchor hole (3), and the first rolled edge (2) is annular; the tray body also comprises a drainage hole (5), a wave pressure arc (6), a plurality of circular pressure protrusions (9) protruding downward, and a second rolled edge (10), the wave pressure arc (6) comprises a plurality of groups of annular pressure concave structures and annular pressure convex structures arranged at intervals, and the second rolled edge (10) is located at the outer edge of the tray body.
[0007] As a further improvement of the rolled anchor tray, the bowl-shaped protrusion (1) is further provided with a plurality of circumferentially distributed rectangular protrusions (4), and the drainage holes (5) are opened on the rectangular protrusions (4).
[0008] As a further improvement of the rolled anchor tray, the tray body is further provided with a pressure groove (8), the pressure groove (8) is annular, and the circular pressure protrusions (9) are circumferentially distributed on the pressure groove (8).
[0009] As a further improvement to the rolled anchor tray, an arc-shaped pressure bend (7) is provided between the wave pressure arc (6) and the pressure groove (8), and its bending direction is opposite to the bending direction of the bowl-shaped protrusion (1).
[0010] Compared with the prior art, the utility model has the following positive effects: (1) by providing a bowl-shaped protrusion, a first rolled edge, a second rolled edge and a wave pressure arc, the stability and bearing capacity of the overall structure of the anchor tray are enhanced; (2) by providing a drainage hole, the retention of water on the contact surface between the anchor and its tray is reduced, thereby reducing the possibility of corrosion of the anchor; (3) by providing a wave pressure arc and a circular pressure convexity, the degree of fit between the tray and the uneven rock mass is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In the figure, 1, bowl-shaped protrusion; 2, first curling edge; 3, anchor hole; 4, rectangular protrusion; 5, drainage hole; 6, wave pressure arc; 7, arc pressure bend; 8, pressure groove; 9, circular pressure convex; 10, second curling edge. DETAILED DESCRIPTION
[0014] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments.
[0015] like Figure 1 and Figure 2 As shown, a rolled anchor tray comprises a tray body, an anchor hole 3 is provided at the center of the tray body, a bowl-shaped protrusion 1 is provided in the tray body, and the anchor hole 3 is opened on the top of the bowl-shaped protrusion 1; the bowl-shaped protrusion 1 is also provided with a plurality of circumferentially distributed rectangular protrusions 4, and the rectangular protrusion 4 is provided with a drainage hole 5 with an aperture of 10 mm; a first rolled edge 2 is provided at the anchor hole 3, and the first rolled edge 2 is annular, and its rolled bending radius is 3.5-4.5 mm, and the rolled edge angle is 170-190 degrees; the tray body also includes a wave pressure arc 6, a plurality of directional A downward protruding circular embossment 9 and a second curling edge 10; the wave arc 6 includes two groups of annular concave embossment structures and annular convex embossment structures arranged at intervals; the disk body is also provided with an annular groove 8, the middle part of its cross-section is flat, with a width of 5mm, and both sides are concave arc-shaped with a bending radius of 10mm; the circular embossments 9 are distributed circumferentially on the groove 8, there are 24 of them, the circular embossments 9 are spherical, with a maximum outer diameter of 10mm and a protrusion of 3mm; the second curling edge 10 is located at the outer edge of the disk body, with a rolling height of 10mm and a rolling angle of 55 degrees.
[0016] When the utility model is used for tunnel construction and underground mining support, first drill a hole in the rock mass, then put the tray on the anchor rod, use the anchor rod trolley or pneumatic drill to gradually push the anchor rod into the rock mass until the circular pressure convexity 9 of the tray contacts the rock mass, and then continue to push the anchor rod, at this time the circular pressure convexity 9 will deform according to the uneven rock mass; continue to push the anchor rod, at this time the wave pressure arc 6 position will elastically deform, thereby providing an initial anchor force for the anchor rod, even if the rock mass changes later, under the action of the elastic deformation of the utility model, the anchor rod still has a large anchoring force. When water in the rock mass flows through the anchor rod wall to the tray, it can be quickly drained through the drainage hole 5, reducing the retention of water on the contact surface of the anchor rod and its tray, thereby reducing the possibility of corrosion of the anchor rod.
[0017] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. The scope of the present invention is defined by the claims rather than the above description.
