Abstract
The utility model discloses a universal shaft broken axis detection device comprising a control box, a wirerope and an alarm; wherein, the control box is internally provided with a limit switch, and a rocker is arranged on the control box. One end of the rocker gets pinned to the control box, and the other end of the rocker is a free rotation end; one end of the wirerope connects with the free rotation end of the rocker, and the other end of the wirerope is fixedly connected with a steadier; the alarm is connected with the limit switch via a signal transmission line. The detection device is characterized by simple structure, easy usage and high accuracy, making the wirerope closely clung to the bottom of the universal shaft. When the universal shaft fractures, the dead weight of the universal shaft leads to deflexibility of the wirerope and underspin of the rocker, thereby enabling the on-off limit switch to send signals to the alarm for timely acoustic-optical warning and for reminding the operator of carrying engine-off service. The rest three universal shafts are prevented from real-time fracture; thereby avoiding safety hazard, improving working efficiency, saving the service time and the cost, and increasing economic benefit.
Description
Technical field
The utility model relates to mechanically operated servicing unit, more particularly, relates to a kind of universal shaft off-axis pick-up unit, and this pick-up unit can detect in real time to the universal shaft off-axis.
Background technology
Molten iron and steel scrap are two big base stocks of pneumatic steelmaking, through the qualified molten iron of blast furnace process by torpedo tank car be transported to steel-making be subjected to the iron hole after, in ladle that molten iron is changed the outfit, and hot-metal bottle weighing chassis is exactly the visual plant that is used for weighing and delivery ladle.See also shown in Figure 1; the horizontal drive device 1 of walking of weighing chassis comprises motor 2; detent 3; reducer casing 4; universal shaft 5 and driving wheel 6; this weighing chassis is except weighing and delivery ladle; also to be used to draw the steel slag case simultaneously; because operating mode; design; many-sided reasons such as spare part quality; four universal shafts 5 of drive part phenomenon of rupture occurs through regular meeting; the accident that the four-way union 51 of four universal shafts 5 ruptures simultaneously can take place when serious; had a strong impact on ordinary production; bring difficulty to plant maintenance, increased maintenance cost greatly; reduced work efficiency; influenced the performance of steel-making production capacity.Phenomenon for the universal shaft fracture, though can be by improving the material of universal shaft, performance parameter and select for use modes such as adjustable frequency motor to solve, but still can't thoroughly stop the phenomenon of universal shaft fracture, and these improvement need bigger investment, tens thousand of at least units, hundreds thousand of at most units, because universal shaft is one of modal web member in the mechanical drive, and the fracture of universal shaft is for mechanical drive, especially heavy-duty machinery, almost be inevitable, but why the major accident that four axles rupture simultaneously takes place, and mainly is because after single universal shaft ruptures earlier, can't in time find, making its excess-three root universal shaft carry in rotation process rapidly increases, the speed of universal shaft deterioration is accelerated rapidly, thereby causes that at short notice moment fractures simultaneously, generally is no more than 12 hours.At present, have only by artificial cyclic check, also without any pick-up unit, but hand inspection is wasted time and energy, and universal shaft can't carry out hand inspection when work, therefore still can't detect in real time universal shaft, can't avoid causing that many universal shafts rupture simultaneously, cause device damage, increase maintenance cost and have potential safety hazard.
The utility model content
At the above-mentioned shortcoming that can't detect in real time the universal shaft off-axis, can't avoid many universal shafts to rupture, increase maintenance cost simultaneously and cause security incident easily that exists in the prior art, the purpose of this utility model provides a kind of universal shaft off-axis pick-up unit, this pick-up unit is simple in structure, easy to use, not only can detect in real time the universal shaft off-axis, but also can report to the police automatically, be convenient in time handle.
For achieving the above object, the utility model adopts following technical scheme:
This universal shaft off-axis pick-up unit comprises:

Wire rope, wire rope one end is connected with the end that rotates freely of rocking arm, and the wire rope other end and a bearing are connected and fixed;
Alarm is connected with limit switch by signal transmission line.
Described alarm is an audible-visual annunciator.
Described alarm further comprises:
The limit switch contact, an end is connected to external power source, and the other end is connected to the input end of relay coil;
Relay, the output terminal of relay contact is connected to pilot lamp and acoustical generator;
Pilot lamp and acoustical generator, pilot lamp and acoustical generator are connected with relay contact.
Described limit switch is open in usual.
In technique scheme, universal shaft off-axis pick-up unit of the present utility model comprises control box, wire rope and alarm, and control box is located on the bracing frame, inside is provided with limit switch, also be provided with rocking arm on the control box, rocking arm one end and control box pin joint, the other end of rocking arm is for rotating freely end; The wire rope other end also is connected and fixed with bearing; Alarm is connected with limit switch by signal transmission line.This pick-up unit is simple in structure, easy to use, accuracy is high; wire rope is close to the universal shaft bottom; when universal shaft ruptures; driving wire rope by universal shaft deadweight effect is bent downwardly; and traction rocking arm backspin; thereby closed limit switch sends signal to alarm; in time carry out sound and light alarm; remind operating personnel to carry out shutdown maintenance; prevented that its excess-three root universal shaft from rupturing simultaneously, stopped potential safety hazard, improved work efficiency; save maintenance time and cost, increased economic benefit.
