This type of anchor support system is generally composed of an anchor rod body, anchoring agent, tray and nut. The specific operation method is to insert the anchor rod body into the anchor borehole where the anchoring agent has been placed and rotate and stir it.

[0006] A fixing ring matched with the multiple connection mechanism is integrally formed on the upper side of the anchor rod surface, and a nut matched with the fixing ring to control the multiple connection mechanism is threadedly connected to the bottom end of the anchor rod.

[0007] Preferably, the multiple connection mechanism includes an adjustment component, an anchor rod reinforcement component and an anti-loosening component, the adjustment component is arranged in the middle of the pallet body, and the anchor rod is fixedly connected in the adjustment component.

[0008] The anchor rod reinforcement component and the anti-loosening component are both arranged in the adjustment component.

[0010] The anchor rod is movably installed in the anchor pipe.

[0011] An angle adjustment groove communicating with the mounting hole is provided on the surface of the tray body, and the anchor pipe is deflected in a fan shape in the angle adjustment groove.

[0012] End rings are provided at both ends of the anchor pipe, and the two end rings are respectively adapted to the fixing ring and the nut, and a plug rod is fixedly connected to the surface of the end ring opposite to the anchor pipe side, and a through hole corresponding to the plug rod is opened at the port of the anchor pipe, and the two plug rods are movably inserted into the corresponding ends of the through hole, and the outer sides of the two plug rods at the opposite ends are rotatably connected with deflection frames, and the two deflection frames are rotatably connected to each other.

[0013] The anchor rod reinforcement component is arranged between two insertion rods, and the anti-loosening component is arranged on the insertion rods.

[0014] A through opening communicating with the through hole and cooperating with the deflection frame is provided on the surface of the anchor pipe, and a clamping groove cooperating with the deflection frame is provided on the side walls of the angle adjustment groove and the mounting hole.

[0015] Preferably, the anchor rod reinforcement assembly includes two inner buckle frames, the two inner buckle frames are rotatably connected to the inner sides of opposite ends of the two insertion rods, and the two inner buckle frames are rotatably connected to each other.

[0016] Preferably, the anti-loosening component includes an inner groove, which is opened on the inner wall of the through hole, the surface of the insertion rod is fixedly connected with an anti-drop buckle on the inner side, and the outer end of the insertion rod is fixedly connected with a rubber ring that matches the through hole and the inner groove.

[0017] Preferably, the number of the insertion rods is four, and the four insertion rods are symmetrically arranged in groups of two along the two end rings.

[0018] Preferably, a fur curtain matching the anchor tube is fixedly connected to the top edge of the inner wall of the angle adjustment groove.

[0019] A method for using a multi-angle matching shaft support tray comprises the following steps:

[0020] S1. Select anchor rods with or without fixing rings according to the hardness of the rock and soil layer at the support point, and drill holes at the support point. Place anchoring agent in the holes, insert the anchor rod body into the holes where the anchoring agent has been placed and rotate and stir. After the anchoring agent, the anchor rod body and the rock wall solidify, align the tray body with the outer end of the anchor rod and insert them, so that the anchor rod is inserted into the anchor pipe, and then screw the nut along the outer end of the anchor rod to install the tray body on the anchor rod. With the help of the blocking effect of the anchor rod, the tray and the rock wall, the anchor rod body is stretched to realize the application of preload force of the anchor support system and achieve the support purpose.

[0021] S2. When the anchor rod needs to be tightened in an inclined state along the pallet body for different rock and soil layers and force effects, the operator can push the pallet body to deflect along the anchor rod, anchor pipe and shaft head after aligning the pallet body along the outer end of the anchor rod, so that the force surface of the pallet body and the tightening angle of the anchor rod are adjusted accordingly. After the adjustment is completed, the nut is screwed in to make the pallet body fit the rock layer, and then the anchor rod is tightened in reverse. In this process, the relatively close rock layer and the nut or the fixing ring and the nut push the end rings at both ends of the anchor pipe to relative displacement, and the insertion rods at both ends follow the end rings and move synchronously along the perforation to relatively squeeze the deflection frame, so that the deflection frame bends outward along the through opening and embeds into the slot, thereby locking the anchor pipe after the angle adjustment.

[0022] S3. When the relatively close rock formations and nuts or the fixing rings and nuts push the end rings at both ends of the anchor pipe for relative displacement, the inserted rods at both ends follow the end rings and move synchronously along the perforations to synchronously squeeze the inner buckle frame, so that the inner buckle frame bends inward in the perforations and buckles against the anchor rods in the anchor pipe, thereby performing secondary locking of the tray body and the anchor rods in the anchor support state, which can effectively prevent the tray body from deflecting along the anchor rods and improve stability during installation and use.

[0023] S4. During daily transportation and carrying, the user can first insert the pallet body and the anchor tube along the end of the anchor rod, and then manually press the end ring to drive the inner buckle frame to simply buckle along the surface of the anchor rod. The rubber ring on the surface of the rod is squeezed and deformed to pass through the perforation into the inner groove to limit the rod, thereby maintaining the current buckling state, avoiding the scattered components of the device from affecting carrying, and further facilitating daily use.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] In the present invention, the tray body is pushed to deflect along the anchor rod, anchor pipe and shaft head, so that the force-bearing surface of the tray body and the tightening angle of the anchor rod are adjusted accordingly. After the adjustment is completed, the nut is screwed in to make the tray body fit the rock layer, and then the anchor rod is tightened in reverse. In this process, the relatively close rock layer and the nut or the fixing ring and the nut relatively push the end rings at both ends of the anchor pipe to relative displacement, and the insertion rods at both ends follow the end rings and move synchronously along the perforation to relatively squeeze the deflection frame, so that the deflection frame bends outward along the through opening and embeds into the slot, so as to lock the anchor pipe after the angle adjustment, and the anchor rod can be tightened in an inclined state along the tray body according to different rock and soil layers and force effects.

[0026] In the present invention, when relatively close rock formations and nuts or fixed rings and nuts push the end rings at both ends of the anchor pipe for relative displacement, the inserted rods at both ends follow the end rings and move synchronously along the perforations to synchronously squeeze the inner buckle frame, so that the inner buckle frame bends inward in the perforations and buckles against the anchor rods in the anchor pipe, thereby performing secondary locking of the tray body and the anchor rods in the anchor support state, which can effectively prevent the tray body from deflecting along the anchor rods and improve stability during installation and use.

[0027] In the present invention, the pallet body and the anchor tube are inserted along the end of the anchor rod, and then the end ring is manually pressed to drive the inner buckle frame to simply buckle along the surface of the anchor rod. The rubber ring on the surface of the insertion rod is squeezed and deformed to pass through the perforation into the inner groove to limit the insertion rod, thereby maintaining the current buckling state, avoiding the scattered components of the device from affecting carrying, and further facilitating daily use.

After the anchoring agent, the rod body of the anchor rod 3 and the rock wall are solidified, the tray body 1 is aligned with the outer end of the anchor rod 3 and inserted so that the anchor rod 3 is inserted into the tray body 1, and then the nut 6 is screwed into the outer end of the anchor rod 3 to realize the installation of the tray body 1 on the anchor rod 3. The anchor rod 3 with a fixing ring 5 can be selected according to the hardness of the rock and soil layer at the support point. It is mainly used to cooperate with the nut 6 to extrude the multiple control mechanism.

[0038] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the multiple connection mechanism 4 includes an adjustment component 41, an anchor rod reinforcement component 42 and an anti-loosening component 43. The adjustment component 41 is arranged in the middle of the pallet body 1, and the anchor rod 3 is fixedly connected in the adjustment component 41;

[0039] The anchor rod reinforcement component 42 and the anti-loosening component 43 are both arranged in the adjustment component 41.

[0040] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the adjustment assembly 41 includes an anchor pipe 411, which is movably connected in the mounting hole 2, and a shaft head 412 is fixedly connected to the lower side of the surface of the anchor pipe 411, and the anchor pipe 411 is rotatably connected in the mounting hole 2 through the shaft head 412;

[0041] The anchor rod 3 is movably installed in the anchor pipe 411;

[0042] The surface of the tray body 1 is provided with an angle adjustment groove 413 connected to the mounting hole 2, and the anchor pipe 411 is deflected in a fan shape in the angle adjustment groove 413;

[0043] Both ends of the anchor pipe 411 are provided with end rings 414, the two end rings 414 are respectively adapted to the fixing ring 5 and the nut 6, and the surface of the end ring 414 is fixedly connected with a plug rod 415 on the side opposite to the anchor pipe 411, and the end of the anchor pipe 411 is provided with a through hole 416 corresponding to the plug rod 415, the two plug rods 415 are movably inserted into the corresponding ends of the through hole 416, and the outer sides of the opposite ends of the two plug rods 415 are rotatably connected with a deflection frame 417, and the two deflection frames 417 are rotatably connected to each other;

[0044] The anchor rod reinforcement assembly 42 is disposed between the two insertion rods 415, and the anti-loosening assembly 43 is disposed on the insertion rods 415;

[0045] A through opening 418 is provided on the surface of the anchor tube 411, which is connected to the through hole 416 and cooperates with the deflection frame 417. A clamping groove 419 which cooperates with the deflection frame 417 is provided on the side walls of the angle adjustment groove 413 and the mounting hole 2. The relatively close rock formations and the nut 6 or the fixing ring 5 and the nut 6 push the end rings 414 at both ends of the anchor tube 411 to relative displacement. The insertion rods 415 at both ends move synchronously with the end rings 414 along the through hole 416 and relatively squeeze the deflection frame 417, so that the deflection frame 417 bends outward along the through opening 418 and embeds into the clamping groove 419, thereby locking the anchor tube 411 after the angle adjustment.

[0046] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the anchor reinforcement assembly 42 includes an inner buckle frame 421, and the number of the inner buckle frames 421 is two. The two inner buckle frames 421 are respectively rotatably connected to the inner sides of the opposite ends of the two insertion rods 415, and the two inner buckle frames 421 are rotatably connected to each other. The deflection frame 417 and the inner buckle frame 421 are rod-shaped components with the same specifications. The two deflection frames 417 and the two inner buckle frames 421 form a diamond-shaped parallelogram structure, and the upper and lower ends of the parallelogram structure are connected to the insertion rod 415 on the same side.

The deflection frame 417 that expands outward is used to embed in the slot 419, and the inner buckle frame 421 that expands inward is used to contact with the anchor rod 3.

[0047] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the anti-loosening component 43 includes an inner groove 431, which is opened on the inner wall of the through hole 416, and the surface of the plug rod 415 is fixedly connected with an anti-drop buckle 432 on the inner side, and the outer end of the plug rod 415 is fixedly connected with a rubber ring 433 that matches the through hole 416 and the inner groove 431.

[0050] A method for using a multi-angle matching shaft support tray comprises the following steps:

[0051] S1. Select the anchor rod 3 with or without a fixing ring 5 according to the hardness of the rock and soil layer at the support point, and drill a hole at the support point. Place an anchoring agent in the hole, insert the rod body of the anchor rod 3 into the hole where the anchoring agent has been placed and rotate and stir. After the anchoring agent, the rod body of the anchor rod 3 and the rock wall are solidified, align the tray body 1 with the outer end of the anchor rod 3 and insert them, so that the anchor rod 3 is inserted into the anchor pipe 411, and then screw the nut 6 along the outer end of the anchor rod 3 to achieve the installation of the tray body 1 on the anchor rod 3. With the help of the obstruction of the anchor rod 3, the tray and the rock wall, the rod body of the anchor rod 3 is stretched to achieve the application of the pre-tightening force of the anchor rod 3 support system, so as to achieve the support purpose;

[0052] S2. When the anchor rod 3 needs to be tightened in an inclined state along the tray body 1 according to different rock and soil layers and force effects, the operator can push the tray body 1 to deflect along the anchor rod 3, anchor pipe 411 and shaft head 412 after the tray body 1 is aligned and inserted along the outer end of the anchor rod 3, so that the force surface of the tray body 1 and the tightening angle of the anchor rod 3 are adjusted accordingly. After the adjustment is completed, the nut 6 is screwed in to make the tray body 1 fit the rock layer, and then the anchor rod 3 is tightened in the reverse direction. In this process, the relatively close rock layer and nut 6 or the fixing ring 5 and nut 6 relatively push the end rings 414 at both ends of the anchor pipe 411 to relative displacement, and the insertion rods 415 at both ends follow the end rings 414 to move synchronously along the through holes 416 to relatively squeeze the deflection frame 417, so that the deflection frame 417 is bent outward along the through opening 418 and embedded in the card slot 419, so as to lock the anchor pipe 411 after the angle adjustment;

[0053] S3, when the relatively close rock formation and nut 6 or the fixing ring 5 and nut 6 push the end rings 414 at both ends of the anchor pipe 411 to move relative to each other, the insertion rods 415 at both ends follow the end rings 414 to move synchronously along the through holes 416 to synchronously squeeze the inner buckle frame 421, so that the inner buckle frame 421 bends inwardly in the through holes 416 and buckles against the anchor rod 3 in the anchor pipe 411, thereby performing secondary locking between the tray body 1 and the anchor rod 3 in the anchor support state, which can effectively prevent the tray body 1 from deflecting along the anchor rod 3, thereby improving the stability during installation and use;

[0054] S4. During daily transportation and carrying, the user can first insert the pallet body 1 and the anchor tube 411 along the end of the anchor rod 3, and then manually press the end ring 414 to drive the inner buckle frame 421 to simply buckle along the surface of the anchor rod 3. The rubber ring 433 on the surface of the insertion rod 415 is squeezed and deformed to pass through the through hole 416 and enter the inner groove 431 to limit the insertion rod 415, thereby maintaining the current buckling state, which can avoid the scattered components of the device affecting carrying and further facilitate daily use.

Technical personnel in this industry should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not used to limit the present invention.

During this process, the relatively close rock layer and the nut (6) or the fixing ring (5) and the nut (6) push the end rings (414) at both ends of the anchor pipe (411) to move relative to each other. The insertion rods (415) at both ends move synchronously with the end rings (414) along the perforations (416) and relatively squeeze the deflection frame (417), so that the deflection frame (417) bends outward along the through opening (418) and is embedded in the slot (419), thereby locking the anchor pipe (411) after the angle adjustment; S3. When the relatively close rock formation and the nut (6) or the fixing ring (5) and the nut (6) push the end rings (414) at both ends of the anchor pipe (411) to move relative to each other, the insertion rods (415) at both ends follow the end rings (414) to move synchronously along the through holes (416) and synchronously press the inner buckle frame (421) relative to each other, so that the inner buckle frame (421) bends inwards in the through holes (416) and buckles against the anchor rod (3) in the anchor pipe (411), thereby performing a secondary locking between the tray body (1) and the anchor rod (3) in the anchor support state, which can effectively prevent the tray body (1) from deflecting along the anchor rod (3), thereby improving the stability during installation and use; S4. During daily transportation and carrying, the user can first insert the pallet body (1) and the anchor tube (411) along the end of the anchor rod (3), and then manually press the end ring (414) to drive the inner buckle frame (421) to simply buckle along the surface of the anchor rod (3). The rubber ring (433) on the surface of the insertion rod (415) is squeezed and deformed to pass through the perforation (416) and enter the inner groove (431) to limit the insertion rod (415), thereby maintaining the current buckling state, avoiding the scattered components from affecting carrying, and further facilitating daily use.
