Hopper protection device of bucket elevator mixing station

Abstract

The invention discloses a hopper protection device of a bucket elevator mixing station, and belongs to the field of concrete mixing. The hopper protection device comprises a frame and a hopper, and ischaracterized in that a first locking fixed block, a first locking movable block and a first locking cylinder are arranged on the frame, and a first protective steel wire rope penetrates through a first positioning block and a second positioning block and is positioned between the first locking fixed block and the first locking movable block; a second locking fixed block, a second locking movableblock and a second locking air cylinder are arranged on the rack, a second protection steel wire rope penetrates 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, a first tensioner is installed on a first lower pulley, and a second tensioner is installed on a second lower pulley. The hopper protection device can effectively prevent the hopper frame and the hopper from falling rapidly after a lifting steel wire rope is broken, is simple in the structure, has the universality, can be used for the hopper protection of various types, and can effectively guarantee the use safety.

Description

technical field [0001] The invention relates to the technical field of concrete mixing machinery and equipment, 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 batching plant is a combined device for centrally mixing concrete, also known as concrete precast field. Due to its high degree of mechanization and automation, its productivity is also very high, and it can ensure the quality of concrete and save cement. With the development of municipal construction, the use of centralized mixing to provide commercial concrete mixing plants has great advantages, so it has developed rapidly, and created conditions for the promotion of concrete pumping construction and the realization of the combined operation of mixing, conveying and pouring machinery. [0003] In the concrete mixing plan...

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
