DETAILED DESCRIPTION

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0016] like Figures 1 to 9 As shown, the present invention discloses a novel anti-slip device for a small box clamp, which adopts the following technical scheme: comprising a shell 1, the shell 1 comprising a rotating chamber 101 and a guide chamber 102, the rotating chamber 101 having guide chambers 102 on both sides, the guide chamber 102 on the outside thereof being a fixed block 103, the fixed block 103 being fixedly connected to the overhead traveling crane, the rotating chamber 101 having a first bearing 4 on the top, an opening 107 on the bottom, the guide chamber 102 having a first vertically arranged guide groove 104 and a second horizontally arranged guide groove 106, the outside of the second guide groove 106 being provided with a guide wheel group 105, the guide wheel group 105 being rotatably connected to the shell 1, the guide wheel group 105 being used to make the first elastic sheet 503 detect deformation to realize steering and auxiliary sliding, the middle part of the shell 1 being rotatably connected to the screw head 2, the screw head 2 comprising a connecting head 201 and a guide head 20 2. There are screw holes and key slots on the connecting head 201. The connecting head 201 is connected to the driving shaft of the overhead crane through the screw holes and key slots. The rotation of the driving shaft can drive the screw head 2 to rotate. A threaded groove is provided on the guide head 202. The threaded groove includes a first threaded groove 203 and a second threaded groove 204. The first threaded groove 203 and the second threaded groove 204 are the same and are arranged in the same direction. The starting points of the two are located on both sides of the guide head 202. A bayonet 205 is provided at the bottom of the guide head 202. The bayonet 205 cooperates with the nut of the clamp bolt 301. A second spring piece 8 is provided at the starting point and end point of the first threaded groove 203 and the second threaded groove 204. The second spring piece 8 is spring steel and has elastic deformation ability. One end of the second spring piece 8 is fixedly connected to the end of the first threaded groove 203 and the second threaded groove 204, and the other end is tilted upward by its own elasticity. Figure 9As shown, when the contact head 505 is located at the uppermost and lowermost ends of the first and second screw grooves 203 and 204, smooth idling is achieved without affecting reverse movement such as Figure 8 As shown, the screw head 2 has anti-disengagement mechanisms 5 on both sides, which include a moving shaft 501, one end of which is a contact head 505, and the other end is rotatably connected to a second rotating wheel 7, which is in contact with the shell 1 and is used to assist sliding. The moving shaft 501 is fixedly connected to a guide piece 502, which is slidably connected to the inside of the first guide groove 104. The end of the guide piece 502 is connected to a first elastic piece 503, which is made of spring steel and has elastic deformation capability. The first elastic piece 503 is located between the guide wheel set 105, and the end of the first elastic piece 503 is connected to a clamping piece 504, which is slidably connected to the inside of the second guide groove 106. The end of the clamping piece 504 is provided with a clamping opening 5041, the inner diameter of which is greater than the outer diameter of the stud of the fixture bolt 301 and less than the outer diameter of the nut. The moving shaft 501 has a first rotating wheel 6 on both sides, which is rotatably connected to the moving shaft 501, and there is a gap between the first rotating wheel 6 and the shell 1.

[0017] The working principle of the present application is as follows: when the small box fixture 3 needs to be disassembled, the clamping opening 205 is aligned with the fixture bolt 301 by controlling the movement of the crown block, and then the entire embodiment is controlled to move downward until the clamping opening 205 is matched with the nut of the fixture bolt 301 and the nut is higher than the position of the clamping piece 504. By controlling the drive shaft to rotate the connecting head 201, the rotation of the connecting head 201 will drive the fixture bolt 301 to rotate and loosen the small box fixture 3. When the screw head 2 rotates, the contact head 505 will move the moving shaft 501 downward along the first and second screw grooves 203 and 204, so that the guide piece 502 moves downward along the first guide groove 104, and the first elastic piece 503 is deformed by the guide wheel set 105 to change direction, so that the clamping piece 504 performs a clamping action, thereby clamping the fixture bolt 301 before the small box fixture 3 is completely loosened, preventing the small box fixture 3 from falling off when disassembling the small box fixture 3.

[0018] When the contact head 505 is located at the end of the first and second screw grooves 203 and 204, the contact head 505 will contact and press the second elastic piece 8, so that the contact head 505 is always located at the same position when the screw head 2 rotates again Figure 8 As shown, when the screw head 2 rotates in the opposite direction, the contact head 505 will move along the first and second screw grooves 203 and 204 before contacting the second elastic piece 8, and the second elastic piece 8 will be reset to the raised state due to its elasticity, and the contact head 505 will move along the first and second screw grooves 203 and 204 Figure 9As shown, when the anti-dropping mechanism 5 is in the limit position, the anti-dropping mechanism 5 and the screw head 2 are in a stable idle state, and reverse rotation enters the working state.
