Automatic loading and unloading brick transport cart of truck-mounted crane

Abstract

An automatic loading and unloading brick transport cart of a truck-mounted crane comprises the truck-mounted crane which is located between a cab and a compartment. The two sides of the lower end of a main boom of the truck-mounted crane are provided with racks I with tooth surfaces facing upwards. A telescopic suspension arm is installed in the main boom. The two sides of the lower end of the top of the suspension arm are provided with racks II with tooth surfaces facing upwards. The two racks II and the two racks I are in butt joint after the suspension arm retracts. The crane is installed on the two racks II through two pairs of gears and is driven by a hydraulic running motor to move along the two racks II. The crane is provided with a lifting winch which is driven by a hydraulic lifting motor. A brick clamp is suspended below the lifting winch through a steel wire rope. The automatic loading and unloading brick transport cart of the truck-mounted crane is provided with the telescopic suspension arm, so that the occupied space for rotation of the suspension arm is reduced greatly; a left movable bottom board and a right movable bottom board are adopted as compartment bottom boards, so that continuous loading and unloading are achieved, and the loading efficiency and unloading efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of automatic loading and unloading, in particular to a truck-mounted crane for automatic loading and unloading of bricks. Background technique [0002] The closest prior art with the present invention is the invention patent "cantilever type automatic loading and unloading brick truck (CN103770686A)" applied by the applicant. Because the boom of the vehicle cannot be stretched and retracted, the rotation of the boom takes up a lot of space. When the loading and unloading site is narrow, it will make loading and unloading difficult, or even impossible to complete the loading and unloading. In addition, there is a pallet on the floor of the car that can slide back and forth. When loading the car, stacks of bricks are loaded on the pallet in sequence.

AI Technical Summary

Problems solved by technology

Because the boom of the truck cannot be stretched and retracted, the boom rotation takes up a lot of space. When the loading and unloading site is narrow, it will cause difficulty in loading and unloading, and even the loading and unloading cannot be completed.

In addition, there is a pallet on the floor of the car that can slide back and forth. When loading the car, stacks of bricks are loaded on the pallet in sequence. Scattered during transportation; when unloading, the pallets are pulled apart in turn to form a certain gap between the pallets, and the bricks are unloaded in turn; this structure is only suitable for single-row use of small vehicles with small widths, and is not suitable for large widths. Large medium and large vehicles use double rows
