Description

Technical Field

[0001] The utility model relates to the technical field of anchor cable trays, in particular to a supporting tray with a reinforced structure. Background Art

[0002] The anchor tray is a critical component of the anchor support system, and its performance directly impacts the anchor's effectiveness. The tray's function is to transfer the thrust generated by the nut's tightening torque to the roof, generating initial anchor force. Simultaneously, it transfers pressure from the tunnel roof to the anchor, generating working resistance. Together, they reinforce the surrounding rock and prevent displacement of the tunnel roof.

[0003] Chinese Patent Publication No. CN220451918U discloses a T-shaped steel belt pallet, relating to the field of coal mining technology. The T-shaped steel belt pallet comprises a main plate, wing plates, and a pallet hole. The main plate protrudes upward to form a pallet groove, and the wing plates are located on the left and right sides of the main plate. The pallet hole is provided on the main plate. This utility model utilizes the main plate and wing plates to increase the contact area with the T-shaped steel belt, improving the preload transfer effect and enhancing the support capacity of the anchor cable beam formed by the T-shaped steel belt and anchor cable.

[0004] In the above patent, the anchor cable is fixed by a T-shaped steel belt tray. When fixing the tunnel, the tray needs to transmit the thrust generated by the nut locking torque to the top wall. Therefore, the anchor cable tray needs to bear a larger pressure. However, the tray in the above patent lacks a reinforcement structure. Therefore, when the above tray is subjected to force, the curvature between the wing plates and the main board on both sides is easily deformed due to pressure, which easily leads to a reduction in support strength and affects the transmission of the locking torque. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a support tray with a reinforced structure so as to solve the technical problems mentioned in the above background technology.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A support tray with a reinforcement structure, comprising a support plate, a reinforcement structure and a fixing structure;

[0008] The support plate is arranged in a regular quadrilateral, a protruding part is arranged on the upper end of the support plate, and the protruding part is in the shape of a four-pointed star, and a groove is arranged on the bottom end of the tray, a rectangular plane is arranged on the top end of the protruding part, and an anchor hole is opened at the center of the rectangular plane;

[0009] The reinforcement structure includes a connecting platform, and reinforcement plates are fixedly arranged at the four corners of the connecting platform. The top of the reinforcement plate is provided with a convex surface that matches the groove.

[0014] Furthermore, the top end of the circular cylinder is provided with an inner concave surface that fits with the groove, and the interior of the circular cylinder is provided with a through hole that is coaxial with the connecting hole.

[0015] In summary, the present invention has at least one of the following beneficial technical effects:

[0016] 1. This support tray with a reinforced structure has an upward arched portion at the top of the support plate, and the arched portion is arranged in a four-pointed star shape, so that each surface of the protruding structure can support each other. Therefore, when the support plate is subjected to force, the arched portion can effectively support the locking torque of the anchor cable. At the same time, since the side walls of the protruding structure are all outwardly convex arc surfaces, the arc surface can disperse the pressure when subjected to force, which can effectively reduce the pressure per unit area, thereby effectively reducing the possibility of deformation of the support plate and improving the stability of the anchor cable fixation.

DETAILED DESCRIPTION

[0026] The present invention will be described in further detail below with reference to the accompanying drawings.

[0027] Example:

[0028] Reference Figures 1-6 The utility model discloses a support pallet with a reinforcement structure 2, comprising a support plate 1, a reinforcement structure 2 and a fixing structure 3;

[0029] The support plate 1 is arranged in a regular quadrilateral shape, and a protruding part 101 is provided at the upper end of the support plate 1, and the protruding part 101 is in the shape of a four-pointed star, and a groove 102 is provided at the bottom end of the tray, and a rectangular plane 103 is provided at the top end of the protruding part 101, and an anchor hole 104 is opened at the center of the rectangular plane 103;

[0030] The reinforcement structure 2 includes a connecting platform 201 , and reinforcement plates 202 are fixedly provided at the four corners of the connecting platform 201 . The top of the reinforcement plate 202 is provided with a raised surface 203 that matches the groove 102 .

[0031] In this embodiment, when installing the support tray, first, the fixing structure 3 is placed on the outer peripheral wall of the anchor bolt, then the reinforcement structure 2 is inserted on the top of the fixing structure 3, and the anchor bolt is inserted into the anchor hole 104. The position of the support plate 1 is manually adjusted so that the four reinforcement plates 202 of the reinforcement structure 2 correspond to the four top corners corresponding to the groove 102 and the protruding part 101, and the anchor cable is locked with a nut;

[0032] By setting the protruding structure, the top of the support plate 1 has an upward arched portion, and the arched portion is arranged in a four-pointed star shape, so that each surface of the protruding structure can support each other. Therefore, when the support plate 1 is subjected to force, the arched portion can effectively support the locking torque of the anchor cable, thereby effectively reducing the possibility of deformation of the support plate 1 and improving the stability of the anchor cable fixation;

[0033] By connecting the platform 201 and cooperating with the reinforcing plate 202, the bending part and the top of the protruding structure are supported, thereby further improving the strength of the protruding structure. In addition, by setting the raised surface 203, the top of the reinforcing plate 202 and the contact part of the groove 102 are more closely fitted, thereby improving the support of the reinforcing structure 2 for the protruding component 101.

[0034] In a further preferred embodiment of the present invention, Figure 1-6 As shown, the fixing structure 3 includes a circular cylinder 301 , a positioning opening 302 is provided at the upper end of the circular cylinder 301 , a conical inner cavity 303 is provided at the bottom end of the circular cylinder 301 , and a plurality of reinforcing angle irons 304 are provided on the inner cavity wall of the conical inner cavity 303 .

The setting of the reinforcing angle iron 304 can increase the contact friction between the circular cylinder 301 and the concrete when fixing the support tray, and can prevent the support tray from rotating with the nut when tightening the nut, thereby improving the stability of the tray after installation.

When the reinforcing plate 202 is inserted into the side cavity 3022, the two side walls of the reinforcing plate 202 fit together with the cavity walls of the side cavity 3022. This facilitates the connection between the circular cylinder 301 and the reinforcing structure 2 while also achieving the purpose of improving the stability of the connection.

[0038] In a further preferred embodiment of the present invention, Figure 1-6 As shown, a connection hole 204 is opened inside the connection platform 201 , and the connection hole 204 is coaxially arranged with the anchor hole 104 .

[0039] In this embodiment, the connection hole 204 is provided for passing an anchor bolt. When the anchor bolt is fixed by a nut, the purpose of fixing the reinforcement structure 2 can be achieved through the support plate 1.

[0040] In a further preferred embodiment of the present invention, Figure 1-6 As shown, the side walls of the protruding parts 101 are all arc-shaped and protrude outward, and the connection between the protruding parts 101 and the flat plate of the support plate 1 is provided with an arc-shaped transition.

[0041] In this embodiment, the outward-convex arc setting can more effectively disperse the pressure when subjected to external force due to the outward-convex shape of the arc, and can effectively reduce the pressure per unit area, thereby improving the overall load-bearing capacity of the protruding component 101.

[0042] In a further preferred embodiment of the present invention, Figure 1-6 As shown, the top of the circular cylinder 301 is provided with an inner concave surface 305 that fits with the groove 102 , and the inside of the circular cylinder 301 is provided with a through hole 306 that is coaxial with the connecting hole 204 .

[0043] In this embodiment, the inner concave surface 305 fits with the inner groove wall of the groove 102, which can improve the contact tightness between the circular cylinder 301 and the protruding component 101, thereby improving the stability of the support tray.
