Description
Technical Field
[0001] The utility model relates to a construction tool, in particular to a trolley for quickly loading and unloading building blocks. Background Art
[0002] At present, blocks are widely used in building walls. The blocks are transported by manufacturers to the construction site, unloaded in batches and piled up in a designated material yard. Each masonry team needs to remove the blocks in the material yard and transport them to the masonry site, which is considered on-site transportation. Workers in each team usually have to complete at least one loading and unloading process before they can transport the blocks to the masonry site. The traditional carts available on the market are usually flatbed trucks or hopper trucks, which are inconvenient to load and transport blocks. There are the following disadvantages: 1) The module of the traditional cart does not match the module of the blocks, and the space cannot be fully utilized. The transportation volume is small at one time and the transportation efficiency is low; 2) The loading and unloading depends on the workers to carry the blocks one by one, which is time-consuming and inefficient. The back and forth transportation increases the possibility of damage to the blocks; 3) The size of the traditional cart does not meet the ergonomics and transportation is laborious. The Chinese utility model with the authorization announcement number CN214240844U discloses a tool cart that is conducive to the loading and unloading and transportation of blocks. The utility model requires the blocks to be transported one by one, which is inefficient. Utility Model Content
