Abstract
The utility model discloses a kind of blast furnace winding speed reducing, on parallel shaft (speed) reducer basis, the cogged axle of each part band, by two ends roller bearings, bearing is arranged on casing, at every step bearing place, axle has the gap protection structure being produced by casing or casing associate member, and after bearing failure, protection structure works, make large inclination can not occur with the axle of gear, still can guarantee gear pair engagement; To bearing implementing monitoring, the telecommunication in time of the temperature rise of bearing and fail message is transmitted simultaneously.
Description
Technical field
The utility model relates to a kind of retarder for blast furnace elevator and lifting mechanism.
Background technique
Blast furnace charging equipment " BF Hoist " is the visual plant in blast furnace ironmaking, requires to have high reliability, Security.At present, truck occurs blast furnace aborning sometimes rushes to summit, falls car, slips the accidents such as car, with regard to its reason, has automatically controlled accident and the large factor of mechanical accident two, and mostly mechanical accident is due to due to part failure.
BF Hoist machinery forms and transmission of power mostly sequentially is: motor, coupling/brake device, retarder, roll device.Be after retarder is in braking link.In retarder, number of spare parts kind is many, rolling bearing quantity is many, rolling bearing belongs to easily damaged parts, failure probability is high, after it lost efficacy, and the meeting run-off the straight of the axle of existing retarder band gear or the possibility of falling, at this moment gear pair can not mesh, power transmission chain fracture, produces two kinds of results: the one, and motor power can not be delivered to truck, and the 2nd, truck is loaded and can not be obtained the effective brake of break and cause truck to rush to summit, slip the accidents such as car.
Model utility content
The purpose of this utility model is for BF Hoist provides a kind of blast furnace winding speed reducing, replaces existing retarder, avoids causing because rolling bearing in retarder loses efficacy that truck rushed to summit, slips the accidents such as car.
To achieve these goals; by the following technical solutions: a kind of blast furnace winding speed reducing; comprise the axle with gear being arranged on parallel shaft (speed) reducer; it is characterized in that: the cogged axle of each part band; its two ends are by the roller bearings being arranged on casing; at every step bearing place, between axle and casing or casing associate member, there is protectiveness gap.
On described casing, be provided with the Detecting element for detection of rolling bearing.
The utility model improves on parallel shaft (speed) reducer basis, and after bearing failure, work in protectiveness gap, and making can run-off the straight with the axle of gear, guarantees that gear pair engagement can not thread off; To bearing implementing monitoring, understand temperature rise and the failure conditions of bearing, and situation is carried out to telecommunication transmission simultaneously, prevent trouble before it happens.
Accompanying drawing explanation
?fig. 1 is the utility model embodiment's structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, the axle 1 of each part band gear is supported by two ends rolling bearing 3, and rolling bearing 3 is arranged on casing 5, the gap protection structure that casing or casing associate member 2 and axle 1 form; Detecting element 6 is equipped with at rolling bearing 3 places on casing 5, the outside output temperature of Detecting element 6, oscillating signal.
When rolling bearing 3 lost efficacy, gap protection structure works, and with the axle 1 of gear, can not tilt because rolling bearing 3 lost efficacy, and gear pair 4 can not be threaded off, and retarder can not rupture from being input to outputting power chain, has protected the safety of blast furnace elevator truck; The temperature rise of simultaneous real-time monitoring rolling bearing 3 and failure conditions, prevention rolling bearing 3 lost efficacy, and submitted to report for repairment in time or change retarder to.
The utility model adopts two measures to guarantee the Security of retarder: the one, use special structure treatment, after losing efficacy, bearings inside speed reducer can guarantee the secondary normal engagement of reducer gear, power transmission chain is unimpeded, motor, break can play useful effect to truck, the 2nd, to bearings inside speed reducer intelligent monitoring, when bearing operation exception and alarm.
Claims (2)
1. a blast furnace winding speed reducing; comprise the axle with gear being arranged on parallel shaft (speed) reducer, it is characterized in that: the cogged axle of each part band, its two ends are by the roller bearings being arranged on casing; at every step bearing place, between axle and casing or casing associate member, there is protectiveness gap.
2. blast furnace winding speed reducing as claimed in claim 1, is characterized in that: on described casing, be provided with the Detecting element for detection of rolling bearing.
