AI Technical Summary
Technical Problem
Conventional grating detachment devices are complex in structure, lack durability, and are costly due to separate components, making them inefficient for lifting and lowering gratings that weigh 15 kg to 50 kg.
Method used
The device integrates a pair of left and right support plates with an axle between them, supporting a pair of wheel members, a handle fixed to a support rod, and includes a reinforcing crossbar, with synthetic resin grips on handle rods, simplifying the structure and enhancing mechanical strength.
Benefits of technology
The integrated design improves durability and reduces manufacturing costs while enabling efficient lifting and lowering of heavy gratings, facilitating quicker attachment and detachment operations.

Abstract
The structure of the main body and the support structure of the wheel members are simplified, and the main body is an integrated structure made of a pair of left and right support plates, with a hook part and a stopper part provided at the front of the pair of left and right support plates, an axle is installed between the rear of the pair of left and right support plates, and a pair of left and right wheel members are provided on the axle. As a result, the mechanical strength of the main body can be increased, and the durability of the device when lifting or lowering the grating can be improved. [Solution] Hooks 3, 3 and stoppers 4, 4 are provided on the front of the support plate members 1a, 1a of the main body 1, an axle 6 is mounted between the rear of the support plate members, wheel members 5, 5 are provided on the axle, a support crossbar 7 is mounted between the support plate members, and a handle part 2 is fixed to the support crossbar.
