Technical Field

[0001] The utility model relates to the technical field of anchor bolts, in particular to an urban rail anchor bolt assembly. Background Art

[0002] Anchor bolts are often used to anchor various pipeline supports or as fasteners for connecting and installing various other objects. Since anchor bolts are easy to install, they can bear loads immediately after installation and can be disassembled and reused when necessary. Therefore, they are widely used in anchoring mechanical equipment and various pipe rack supports. In the process of urban rail construction, anchor bolts are often needed to fix the various connecting parts.

Two U-shaped rods 10 are fixedly installed on one side of the connecting block 9, and annular blocks 11 are rotatably installed on the two U-shaped rods 10, and hinged rods 12 are fixedly installed on the two annular blocks 11. Connecting blocks 16 are fixedly installed on the ends of the two hinged rods 12 away from the two annular blocks 11. The two connecting blocks 16 are circular, and the two connecting blocks 16 are slidably installed in the accommodating groove 6. Sliding holes 13 are provided on the two hinged rods 12, and connecting rods 14 are fixedly installed on the inner walls of both sides of the annular groove 7. The same annular rod 15 is fixedly installed on the ends of the two connecting rods 14 away from each other. The annular rod 15 and the two U-shaped rods 10 are located on the same horizontal line to ensure that after the two hinged rods 12 are subsequently adjusted to a horizontal state, the two hinged rods 12 can maintain sliding contact with the annular rod 15, and the annular rod 15 is slidably installed in the two sliding holes 13.

[0023] In order to reduce the wear on the receiving groove 6 and the two connecting blocks 16 , a protective pad is fixedly installed on the inner wall of the receiving groove 6 , and the protective pad is in contact with the two connecting blocks 16 .

[0024] A second annular groove is provided on one side of the rotating block 8 , a bearing is fixedly mounted on the inner wall of the second annular groove, and the inner wall of the bearing is fixedly sleeved on the adapter block 9 .

[0025] In order to provide space for accommodating the two connecting blocks 16 when the two hinge rods 12 are subsequently placed together in the annular groove 7 , a recessed groove is provided on the inner wall of the annular groove 7 , and the recessed groove is adapted to the two connecting blocks 16 .

[0027] The working principle of the urban rail anchor bolt assembly provided by the utility model is as follows:

[0028] After the screw rod 1 is installed and the nut 5 is also installed, the two hinged rods 12 can be rotated. The two hinged rods 12 will rotate with the two U-shaped rods 10 as the center of the circle, and the two connecting blocks 16 will be moved out of the annular groove 7 and will slide out of the two protective pads. After the two connecting blocks 16 are adjusted to a suitable position, the two connecting blocks 16 will be aligned with the accommodating groove 6, and then the rotating block 8 is rotated. The rotating block 8 will slide to the left in the annular groove 7, and the rotating block 8 will come into rotational contact with the adapter block 9 while rotating. Due to the cooperation restriction of the two connecting rods 14 and the annular rod 15, the adapter block 9 can only slide horizontally under the drive of the rotating block 8. While the adapter block 9 moves, the two hinged rods 12 and the two connecting blocks 16 are driven by the two U-shaped rods 10, and the two connecting blocks 16 will slide into the accommodating groove 6 at the same time until the two connecting blocks 16 are in contact with the protective pads in the accommodating groove 6, and then the adjustment of the rotating block 8 can be stopped.

[0029] Compared with the related art, the urban rail anchor bolt assembly provided by the utility model has the following beneficial effects:

[0030] In the utility model, an annular groove 7 is provided on the screw rod 1 for accommodating and installing a rotating block 8, i.e., a related mechanism, so as to ensure that the normal use of the screw rod 1 is not affected. After the nut 5 is installed in place, the two hinged rods 12 together with the two connecting blocks 16 are moved out of the annular groove 7, and the positions of the two hinged rods 12 and the two connecting blocks 16 are adjusted by adjusting the rotating block 8. The two hinged rods 12 and the two connecting blocks 16 support one side of the nut 5, thereby preventing the nut 5 from automatically rotating due to friction, thereby ensuring the fit and controllability of the nut 5 and the screw rod 1.
