Description

Technical Field

[0001] This utility model relates to the field of mine goaf filling technology, specifically to a self-locking lifting rod for rapid suspension in filling mining. Background Technology

[0002] In the treatment of mined-out areas, vertical rows of reinforcing bars are typically suspended in the goaf as a framework for the filling material to improve its strength. The strength of the filling material has a significant impact on subsequent underground mining activities. Currently, the reinforcing bars used in goaf areas are usually 12mm diameter round steel bars. The ends of the reinforcing bars are suspended from pre-installed lifting rings in the roof, and the tails pass through the bottom reinforcing mesh. They are then manually bent and wrapped together to secure them in the goaf. Due to limitations in on-site operating conditions, the angle of the pre-installed lifting rings is sometimes difficult to quickly align with the hooks at the ends of the reinforcing bars, requiring multiple attempts to succeed during construction. Furthermore, the manual bending and wrapping of the reinforcing bars is labor-intensive, and the varying bending positions result in differences in the overall tensile strength of the reinforcing bars. Affected by on-site excavation and blasting activities, this leads to localized areas of low strength in the filling material, increasing the operational risks at the construction site.

[0003] Therefore, a self-locking lifting rod for rapid suspension in filling mining has been developed to reduce the labor intensity of underground personnel and improve the stability of the filling body. Utility Model Content

[0004] To address the problems of existing technologies, the purpose of this utility model is to provide a self-locking lifting rod for rapid suspension in filling mining, which facilitates operators in quickly completing the connection of the filling body skeleton, reducing the workload of operators, and ensuring the smooth progress of filling work.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A self-locking lifting rod for rapid suspension in filling mining includes a lifting rod and a locking body. One end of the lifting rod body is provided with an end hook, and the end of the end hook is provided with an easy-hanging head. The other end of the lifting rod body is provided with a bent section, and the end of the bent section is provided with a hook-connecting head. The bent section on the lifting rod body is movably connected to a sliding locking hole. The outer wall of the sliding locking hole is welded with fixed locking holes side by side. A cylindrical nut is welded to the sliding locking hole, and a limit bolt is provided on the cylindrical nut.

[0007] Preferably, the cylindrical nut is in communication with the sliding lock hole, and a washer is connected to the limiting bolt by a thin wire.

[0008] Preferably, the easy-hanging head is deflected 30° outward from the main body of the suspension rod, and the bending section is deviated 30° from the main body of the suspension rod.

[0009] The beneficial effects of this utility model are as follows:

[0010] This utility model discloses a self-locking lifting rod for rapid suspension in filling mining. A hook head is provided at the bent section of the lifting rod body. The bent section passes through a sliding locking hole, and after bending, the hook head is engaged in a fixed locking hole. A gasket is placed into the sliding locking hole, and the limiting bolt is tightened to complete the overlapping of the filling body skeleton. This reduces the labor intensity of underground personnel, avoids roof collapse accidents caused by on-site excavation and blasting activities, and creates better conditions for safe underground operations.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1 , Figure 2 , Figure 3 The utility model shown is a self-locking lifting rod for rapid suspension in filling mining. The lifting rod body 1 is made of round steel with a diameter of 12mm and a length of 5300mm. One end of the lifting rod body 1 is provided with an end hook 2, which is a semi-circular hook. The end of the end hook 2 is provided with an easy-hanging head 3, which is 50mm long and deflected 30° outward from the lifting rod body. The other end of the lifting rod body 1 is provided with a bent section 4, which is 600mm long and deflected 30° from the lifting rod body. The end of the bent section 4 is provided with a hook head 5.

[0017] The bent section 4 on the main body 1 of the suspension rod is movably connected to a sliding locking hole 6. A fixed locking hole 7 is welded side by side to the outer wall of the sliding locking hole 6. The two locking holes are made of hollow round tubes with a height of 50mm and a diameter of 15mm, which are welded together side by side. The cylindrical body has a wall thickness of 0.2mm. A washer 9 is connected to the sliding locking hole 6. A cylindrical nut 8 is welded to the sliding locking hole 6. The cylindrical nut 8 is connected to the sliding locking hole 6. The cylindrical nut 8 is 20mm long and has a radius of 5mm. A limit bolt 9 is provided on the cylindrical nut 8.

[0018] In use, the 30° angle of the easy-hanging head 3, set by the end hook 2 of the lifting rod body 1, facilitates the suspension of the lifting rod body 1 in the top plate lifting ring. The bent section 4 of the lifting rod body 1 passes through the bottom reinforcement mesh and then passes through the sliding lock hole 6 again. After bending the bent section 4 at a suitable position, the hook head 5 is inserted into the fixed lock hole 7. Then, the washer 10 connected to the tail of the limiting bolt 9 is placed into the sliding lock hole 6, with the arc opening of the washer 10 facing the lifting rod body 1. Tighten the limiting bolt 9 to ensure that the lock body is not loose. This completes the overlap of one skeleton of the filling body. Repeat the above operation until the overlap of the filling body skeleton is completed. This can reduce the labor intensity of underground personnel, avoid roof collapse accidents caused by on-site excavation and blasting activities, and create better conditions for safe underground operations.

[0019] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
