Novel belt tensioning device of forearm frame of bucket-wheel stacker reclaimer

Abstract

The invention discloses a novel belt tensioning device of a forearm frame of a bucket-wheel stacker reclaimer. The novel belt tensioning device of the forearm frame of the bucket-wheel stacker reclaimer comprises a tension pulley, a bend pulley and a threaded rod tensioning device, wherein the threaded rod tensioning device is composed of a supporting seat frame, a handwheel, a threaded rod and atension pulley, the supporting seat frame is used for fixing the tension pulley and is installed on the outer sides of a left web and a right web of the forearm frame; microscler kidney-shaped holes are formed in the left web and the right web; a shaft of the tension pulley penetrates through the microscler kidney-shaped holes and is connected with the supporting seat frame; the tension pulley isconnected to one end of the threaded rod, and the handwheel is connected to the other end of the threaded rod; a threaded-shaped profile steel rod is arranged on the middle part of the threaded rod, and the threaded-shaped profile steel rod penetrates through a screw opening fixed part of the supporting seat frame and internally meshes with the screw opening fixed part; an upper guide rail and a lower guide rail are arranged on the inner side of the supporting seat frame; a bearing seat of the tension pulley is clamped into the upper guide rail and the lower guide rail of the supporting seat frame to enable the tension pulley to move horizontally rather than move left and right under the drive of the threaded rod; the bend pulley is arranged oppositely at a position slightly below the tension pulley; and the tension pulley and the bend pulley are in S-shaped connection. According to the novel belt tensioning device of the forearm frame of the bucket-wheel stacker reclaimer, the overallweight of the bucket-wheel stacker reclaimer is reduced greatly, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to a belt counterweight structure of a front arm frame of a bucket wheel stacker and reclaimer, in particular to a screw belt tensioning device. Background technique [0002] Bucket wheel stacker-reclaimer is an efficient equipment for continuous loading and unloading of bulk bulk materials in modern industry. Because it has dual functions of reclaiming and stacking materials, it is widely used in ports, docks, metallurgical plants, cement plants, steel plants, and coking plants. The stacking and reclaiming operations of bulk materials (ore, coal, coke, sand and gravel) storage yards such as coal storage plants, power plants, etc., can greatly improve production efficiency. [0003] The bucket wheel stacker reclaimer relies on the conveyor belt on the front arm frame to continuously rotate to convey materials. There are many belt support rollers installed on the forearm frame, and the belts are attached to the support rollers and...

Problems solved by technology

This is equivalent to an increase of 20 to 40 tons in the weight of the bucket wheel stacker and reclaimer, which not only increases the load and wastes the output power during the operation of the bucket wheel stacker reclaimer, but also increases the manufacturing capacity of the bucket wheel stacker reclaimer. cost
