in practice, as shown in fig. 2 to 5, the self-locking mechanism comprises:
a locking plate 210 fixed to the fixing beam 100 and the locking plate 210 being disposed in a transverse direction;
the self-elastic bolt device is arranged on the polishing trolley 10, and a bolt body 221 of the self-elastic bolt device transversely extends out of a preset length when not subjected to external force;
the bolt body 221 of the self-springing bolt device extends out and is hung on the top surface of the locking plate 210, so that the sanding trolley 10 is locked at a preset locking position.
The locking plate that transversely sets up and the spring bolt body that transversely stretches out have realized polishing the dolly and have locked in predetermineeing the locking position when the spring bolt body that transversely stretches out and hangs at the top surface of locking plate. Due to the fact that the self-elastic type spring bolt device and the polishing trolley are installed, the polishing trolley is locked at a preset locking position through a simple structure, and the polishing trolley is prevented from descending.
Specifically, as shown in fig. 2, the locking plate 210 is transversely fixed to the side of the fixing beam facing into the rail.
Thus, the locking plate 210 is positioned above the inside of the rail.
In an implementation, as shown in fig. 2 to 5, the self-locking mechanism further includes:
a guide push rod 222 rotatably connected to the inner side of the fixed beam 100 and located above the locking plate 210, wherein when the open end of the guide push rod 222 rotates to the locking plate 210, the open end of the guide push rod 222 protrudes from one end of the locking plate 210 facing the polishing trolley;
wherein:
when the sanding trolley 10 is locked at a preset locking position, the bolt body 221 extends out of the top surface of the locking plate 210 and is positioned below the guide push rod 222;
when the lifting mechanism drives the grinding trolley 10 to ascend from a preset locking position, the bolt body 221 ascends to be close to the guide push rod 222, and then the guide push rod 222 is pushed from bottom to top to rotate upwards until the bolt body 221 is higher than the guide push rod 222, so that the guide push rod 222 rotates below the bolt body 221; the lifting mechanism continues to drive the sanding trolley 10 to move downwards, the latch body 221 approaches the guide push rod 222 from top to bottom, moves downwards along the guide push rod 222 and the guide push rod 222 pushes the latch body 221 to retract, and the latch body 221 passes through the open end of the guide push rod 222 and one end of the locking plate 210 facing the sanding trolley downwards.
