DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0019] Embodiment: as Figures 1-7As shown, this utility model provides a self-locking joint device for optimizing the tilt angle of anchor plates, including an anchor ring assembly 1, an anchor plate assembly 2, and a fixing assembly 3. The anchor ring assembly 1 includes two mirror-distributed semi-rings 101, each with a conical hole 103. The two semi-rings 101 can be assembled into a complete anchor ring using bolts and nuts, so that the conical holes 103 in the two semi-rings 101 form a complete conical hole 103. The anchor plate assembly 2 includes two mirror-distributed clamping pieces 201 and a mounting frame 203. The top of the clamping piece 201 is slidably engaged on the lower surface of the mounting frame 203, allowing the clamping piece 201 to slide on the mounting frame 203. The two clamping pieces 201 move synchronously. Both clamping pieces 201 are conical in shape and have clamping grooves 202 inside. Each clamping piece 201 is equipped with a limit component 4, which includes a wedge-shaped locking block 401. Each clamping piece 201 has a sliding groove 2011 inside, and the locking block 401 is slidably installed in the corresponding sliding groove 2011. Each sliding groove 2011 has a spring 402 fixedly installed inside, and one end of the spring 402 is fixedly connected to one end of the locking block 401. The inner walls of the conical holes 103 of the two semi-rings 101 are provided with multiple annular grooves 1 evenly distributed vertically. 04, and one end of the clamping block 401 can be clamped in the corresponding annular groove 104, so that the clamping end of the steel strand passes through the conical hole 103 in the two semi-rings 101 and through the mounting frame 203. Then, the two clamping pieces 201 clamp the steel strand through the clamping groove 202, and the small end of the two clamping pieces 201 is inserted into the conical hole 103 in the two semi-rings 101 from the large end of the conical hole 103. The mounting frame 203 is then fitted onto the corresponding two threaded rods 302. Applying a pulling force from the bottom end of the steel strand will cause the clamping pieces 201 to move towards the small end of the conical hole 103. The conical surface squeezes the clamping pieces 201, and the clamping pieces 201 and the conical hole 103... The interference fit causes the clamp 201 to engage with the steel strand. The greater the tension, the greater the friction between the clamp 201 and the steel strand, creating a self-locking effect that "tightens as it is pulled". When the clamp 201 moves within the conical hole 103, the locking block 401 inside the clamp 201 will gradually lock into the annular groove 104 within the conical hole 103 by the elastic force of the spring 402, thus limiting the clamp 201 and preventing it from moving in the opposite direction and losing its clamping force on the steel strand. Finally, the clamp 201 can be limited by the fixing component 3, which can fix the clamp 201 again. With the help of the limiting component 4, the clamp 201 can be prevented from shifting due to the vibration of the carrier.

[0020] The upper and lower ends of the two clamping blocks 401 are fixedly installed with limiting blocks 4011, two limiting grooves 2012 are symmetrically arranged in the two sliding grooves 2011, and the limiting blocks 4011 are slidingly clamped in the corresponding limiting grooves 2012, so that the clamping block 401 slides in the sliding groove 2011 along the limiting groove 2012 through the limiting block 4011, and the limiting groove 2012 can also limit the clamping block 401, preventing the clamping block 401 from sliding out of the sliding groove 2011 in the clamping piece 201.

[0021] The upper and lower ends of the two half rings 101 are detachably sleeved with the fixing hoops 102, the two half rings 101 can be assembled into a complete anchor ring through bolts and nuts, and the two half rings 101 are fixed by sleeving the fixing hoops 102, so that the two half rings 101 are prevented from separating during use, and the anchor ring is arranged in a split type, so that the clamping piece 201 can be conveniently disassembled from the anchor ring for subsequent recycling.

[0022] The fixing assembly 3 comprises a plurality of threaded rods 302 arranged in a ring shape, the threaded rods 302 are fixedly installed at the top ends of the two half rings 101, the mounting frame 203 can be sleeved on the corresponding two threaded rods 302, a cover plate 301 is sleeved on the plurality of threaded rods 302, the lower surface of the cover plate 301 can be in contact with the top ends of the two clamping pieces 201, a locking nut 303 is threadedly installed on each of the plurality of threaded rods 302, the cover plate 301 can be sleeved on the threaded rod 302, and the locking nut 303 is tightened to limit and fix the clamping piece 201.

[0023] Working principle: in use, the clamping end of the steel strand passes through the taper hole 103 in the two half rings 101, passes through the mounting frame 203 and the cover plate 301, then the two clamping pieces 201 clamp the steel strand through the clamping grooves 202, and the small end of the two clamping pieces 201 is inserted into the taper hole 103 in the two half rings 101 from the large end of the taper hole 103, the clamping piece 201 moves to the small end of the taper hole 103 under the tension of the bottom end of the steel strand, the taper extrudes the clamping piece 201, the interference fit between the clamping piece 201 and the taper hole 103 causes the clamping piece 201 to engage with the steel strand, the greater the tension, the greater the friction between the clamping piece 201 and the steel strand, forming a self-locking effect of "the tighter the pull", when the clamping piece 201 moves in the taper hole 103, the clamping block 401 in the clamping piece 201 is gradually clamped in the annular clamping groove 104 in the taper hole 103 through the elastic force of the spring 402, limiting the clamping piece 201, preventing the clamping piece 201 from moving reversely and losing the clamping force on the steel strand, finally, the cover plate 301 is sleeved on the threaded rod 302, and the locking nut 303 is tightened to limit and fix the clamping piece 201, cooperating with the limiting assembly 4, which can prevent the clamping piece 201 from being displaced due to vibration of the carrier.
