Hopper protection device for bucket-lift mixing station

Abstract

The invention discloses a hopper protection device for a bucket lifting mixing station, which belongs to the field of concrete mixing, and includes a frame and a hopper, and is characterized in that: the frame is provided with a first locking fixed block, a first locking movable block and a first Lock the cylinder, the first protective wire rope runs through the first positioning block and the second positioning block and is located between the first locking fixed block and the first locking movable block; the frame is provided with a second locking fixed block, a second Lock the movable block and the second locking cylinder, the second protective wire rope runs through the third positioning block and the fourth positioning block and is located between the second locking fixed block and the second locking movable block, and the first lower pulley is equipped with The first tensioner, the second tensioner is installed on the second lower pulley. The invention can effectively prevent the rapid fall of the hopper frame and the hopper after the lifting wire rope is broken, has a simple structure and is versatile, can be used for various types of hopper protection, and can effectively guarantee the safety of use.

Description

technical field [0001] The invention relates to the technical field of concrete mixing machinery, in particular to a hopper protection device for a bucket lifting mixing station. Background technique [0002] Concrete mixing plant includes mixing host, material weighing system, material conveying system and material storage system. Concrete mixing plant is a combined device used to centrally mix concrete, also known as concrete prefabrication field. Due to its high degree of mechanization and automation, its productivity is also high, and it can ensure the quality of concrete and save cement. It is often used in large and medium-sized water conservancy, electric power, bridges and other projects with large concrete engineering volume, long construction period, and concentrated construction sites. With the development of municipal construction, it is of great advantage to use centralized mixing to provide commercial concrete mixing plants, so it has been developed rapidly, a...

Problems solved by technology

[0007] The anti-fall bucket device of the bucket lifting mixing station disclosed in this patent document, during the lifting process of the hopper, when the lifting wire rope breaks suddenly or the connecting device breaks unexpectedly, the wedge-shaped block extends into the bucket under the double action of the pulley frame and the tension spring. In the center hole of the anti-falling block, the steel wire rope is automatically hugged in an instant, so that the hoisting bucket stops in time and stably, so as not to fall into the bottom of the pit below the track; however, because the steel wire rope is fixed on each track, when the hopper moves up and down, the steel It does not move, so the anti-falling bucket device must be made on the hopper; the structure of the hopper is relatively complicated, the production is troublesome, and it is prone to failure; the force of the hopper and the loading weight of the hopper cannot be displayed in real time, and the safety hazard of wire rope breakage is very likely to occur, and the safety is poor
