Abstract

The utility mode relates to a counter weight tensioning device for a bucket-wheel reclaimer, which consists of a frame, a bearing seat connected with the frame, a fixed shaft connected with the bearing seat, and a roller and a counter weight tightly matched with the fixed shaft. Spouts I are arranged at the two sides of the integral bearing seat, spouts II matched with the spouts I are arranged on the frame, and the counter weight is arranged on a U-shaped counter weight support which is connected with the bearing seat. The counter weight tensioning device of the bucket-wheel reclaimer has a protection function on a steel structure and the roller of the frame, so that the balance of the whole frame is corrected, a belt is prevented from deviating, the safety property of equipment and the working efficiency of units are enhanced, the labor intensity of operators is reduced, and the maintenance cost of the equipment is lowered.

Description

Bucket wheel reclaimer counterweight tightening device

Technical field

The utility model relates to the bucket wheel reclaimer, specifically belongs to the counterweight tightening device of bucket wheel reclaimer.

Background technology

Arm belt tightening device before the utility model, it is because clump weight is one is connected and fixed of punching bolt, make whole counterweight center of gravity vertically downward, cause balance quality poor, cause whole counterweight frame both sides unbalance stress counterweight frame to have the rugged integral inclination phenomenon in both sides, therefore belt is in operation process, because frequent friction formation groove between belt deviation and the counter-balanced carriage often appears in unbalance stress; Belt rubs in groove and makes the belt major injury again and need often to change; The arm belt sideslip makes belt returning charge phenomenon serious, and causes the belt head to increase the glue surface wear of face wheel, afterbody bend wheel, cylinder, also can make long-pending ore deposit, weighting distribution wheel place many and even cause cylinder to break and change; The generation of belt chain mark phenomenon is wrapped on the drum shaft belt steel rope, the fault of cause that drum shaft is pulled, bearing failure and belt being torn, and the workman to overhaul cleaning labour intensity big.

The utility model content

The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of counterweight balance good, and clump weight is placed steadily, equipment such as easy damaged bearing and belt not, the counterweight tightening device of the bucket wheel reclaimer that labor intensity of operating staff is less.

Realize the technical measures of above-mentioned purpose:

Bucket wheel reclaimer counterweight tightening device, by framework, with framework bonded assembly bearing seat, with bearing seat bonded assembly anchor shaft, form with the friction tight cylinder of anchor shaft, clump weight, its both sides in the integrated shaft bearing are provided with chute one, are provided with the chute two that matches with chute one on framework; With bearing seat bonded assembly U-shaped clump weight support, clump weight is placed on the U-shaped clump weight support.

It is characterized in that: the bottom of U-shaped clump weight support is a flute profile.

The utility model compared with prior art; steel structure and cylinder to framework have protective effect; corrected the balance of whole framework; prevented the phenomenon of belt deviation; device security performance and unit operation rate have been improved; alleviate labor intensity of operating personnel simultaneously, reduced the maintenance of equipment cost.

The specific embodiment

Be described further below in conjunction with accompanying drawing:

Bucket wheel reclaimer counterweight tightening device, by framework 1, with framework 1 bonded assembly bearing seat 4, with bearing seat 4 bonded assembly anchor shafts 2, form with anchor shaft 2 friction tight cylinders 3 and clump weight 5, during operation, cylinder 3 rotates around anchor shaft 2.Bearing seat 4 is processed as all-in-one-piece, and is processed with chute 1 in the both sides of integrated shaft bearing 4; Be processed with the chute 27 that matches with chute 1 on framework 1, integrated shaft bearing 4 can be done along chute 27 and move up and down; Connect U-shaped clump weight support 8 by bolt or welding or bearing pin on integrated shaft bearing 4, clump weight 5 is placed on the bottom of U-shaped clump weight support 8 or in the groove of bottom processing.

Claims

1. bucket wheel reclaimer counterweight tightening device, by framework, with framework bonded assembly bearing seat, with bearing seat bonded assembly anchor shaft, form with the friction tight cylinder of anchor shaft, clump weight, it is characterized in that: be provided with chute one in the both sides of integrated shaft bearing, on framework, be provided with the chute two that matches with chute one; With bearing seat bonded assembly U-shaped clump weight support, clump weight is placed on the U-shaped clump weight support.

2. bucket wheel reclaimer counterweight tightening device as claimed in claim 1, it is characterized in that: the bottom of U-shaped clump weight support is a flute profile.
