Description

Locking mechanism for curing furnace trolley

Technical Field

The utility model relates to a, especially relate to a locking mechanism for curing oven trolley.

Background

When some large-sized workpieces are processed, because the workpieces are large in size and heavy in weight, the workpieces need to be placed on the trolley through a crane, then the trolley is transported to a processing position along the I-shaped rail, but because the workpieces are heavy in weight, when the trolley transports the workpieces, the trolley can cause large impact force due to inertia, if the trolley and the I-shaped rail cannot be locked safely and reliably, the trolley can possibly slide out of the rail, or the workpieces fall off the trolley, and finally equipment damage is caused. Therefore, the locking of the trolley on the track needs to be ensured, and the rigid connection between the trolley and the track is realized by adopting a mode of combining an axial set screw and a lateral set screw with an iron wire in the prior locking of the trolley and the track. When the test equipment has light weight and small rotational inertia, the locking mode can effectively ensure the smooth test. However, when the test equipment has large mass and large rotational inertia, and the vibration impact alternating force is very large when the test equipment is frequently braked and runs at high speed for a long time in the test process, the fastening screw is easy to loosen and the steel wire is broken in the test process in the connection mode, so that the relative motion relationship exists between the trolley and the track, and the condition can bring great potential safety hazards to the equipment and personnel. Meanwhile, the fastening mode is inconvenient to operate, time-consuming, labor-consuming, poor in safety and reliability, and has the danger of scratching and damaging the track and the trolley.
