Abstract

The utility model discloses a bearing box gripping apparatus which is used on a breaker roll of a four-roll breaker of a steelmaking enterprise and comprises adjustable gripping plates and an inserting plate. The gripping plates are two straight plates, a plurality of corresponding parallel inserting openings are arranged on the two straight plates, the inserting plate is a straight plate, and two ends of the straight plate match with the inserting openings of the adjustable gripping plates. During usage, the gripping apparatus is fixedly sleeved on positioning tables on two sides of a bearing box at first, the inserting plate is adjusted to be positioned according to the axial distance of the bearing box to be detached, then a jack is placed between a spindle end of a spindle of the breaker roll and the inserting plate, and the bearing box is detached by the aid of the hydraulic jack. Compared with an existing gripping tool for crusher rolls, the bearing box gripping apparatus has the advantages that the bearing box gripping apparatus is simple in structure, light in weight, small in size, convenient to manufacture and high in efficiency, positions at which active and passive bearing boxes of breaker rolls are gripped can be adjusted easily, the bearing boxes are gripped conveniently and quickly, and time and labor are saved. In addition, according to statistics, bearing box gripping work efficiency can be improved by 30% at least, and the bearing box gripping apparatus is high in applicability and wide in application range.

Description

The bearing box gripping apparatus

One, technical field

The utility model relates to a kind of adjustable special-purpose gripping apparatus of bearing box of breaker roll use of steel-making enterprise four-roller crusher.

Two, background technology

Four-roller crusher is the disintegrating apparatus that iron and steel metallurgical industry generally uses, and is used for pulverizing broken Jiao, anthracite.This equipment is pulverized material through the rotation of breaker roll.Because breaker roll directly contacts with material, need regularly change., weight big because of the breaker roll volume complex installation process, is complicatedly brought difficulty to assembly working about 3000KG.General enterprise is relatively backward to the method that it overhauls employing, all is to rely on manpower to overhaul fully.When the active and passive bearing box of dismounting breaker roll; Because of the dismounting grab handle heaviness of using is praised difficulty; And, causing the bearing box take-down time long because of active and passive bearing box wheelbase has nothing in common with each other so need often adjustment to grasp distance, inefficiency and labour intensity are big.

Three, summary of the invention

The purpose of the utility model provides a kind of bearing box gripping apparatus of special use, to improve the operating efficiency in the breaker roll unloading process and to reduce maintainer's labour intensity.

The technical scheme that the utility model adopts is: the bearing box gripping apparatus is made up of adjustable grab plate and plate, and the adjustable grab plate is two straight plates, on two straight plates, a plurality of corresponding parallel sockets is arranged; Plate is the straight plate that the socket of two ends and adjustable grab plate adapts.

During use, gripping apparatus is enclosed within on the positioning table on bearing box both sides fixes earlier.According to the wheelbase size of the bearing box that will dismantle, adjust The attracted numbers, then jack is placed between the axle head and plate of breaker roll main shaft, utilize hydraulic jack that bearing box is unloaded.

The utility model is compared with existing breaker roll gripping tool, has following characteristics:

1, simple in structure, in light weight, volume is little, easily manufactured.

2, the adjustment of the active and passive bearing box of breaker roll crawl position is easy, and the bearing box extracting is convenient and swift, time saving and energy saving, efficient is high.According to statistics, can improve bearing box and grasp operating efficiency more than 30%.

3, strong, the applied range of applicability.

Five, the specific embodiment

Four-roller crusher bearing box gripping apparatus is made up of adjustable grab plate 1 and plate 2; Process adjustable grab plate 1 and plate 2 with Q235 δ 12mm steel plate according to bearing box 4 appearance and size sizes; Two positioning tables that utilize the bearing box both sides respectively to have; Gripping apparatus is fixed on the positioning table, is hydraulic jack 3 between the axle head of breaker roll main shaft 5 and the plate 2.Plate 2 spacings can be adjusted according to wheelbase size, the position difference of the active and passive bearing box 4 that grasps.Utilize hydraulic jack that bearing box 4 is unloaded from breaker roll 6.

Claims

1. bearing box gripping apparatus, it is characterized in that: it is made up of adjustable grab plate (1) and plate (2), and adjustable grab plate (1) is two straight plates, on two straight plates, a plurality of corresponding parallel sockets is arranged; Plate (2) is the straight plate that the socket of two ends and adjustable grab plate (1) adapts.
