Abstract
The utility model discloses a misfunction alarm device of a hydraulic brake. The misfunction alarm device comprises a limiting striking ruler, an electric limiting stopper and an alarm mechanism, wherein the electric limiting stopper is used for detecting the limiting striking ruler, and the alarm mechanism is used for receiving output signals of the electric limiting stopper. The limiting striking ruler is fixedly arranged on a brake lever of the hydraulic brake, the electric limiting stopper is fixedly arranged on a brake spring outer shell of the hydraulic brake, and the output end of the electric limiting stopper is electrically connected to the input end of the alarm mechanism. When the hydraulic brake is abnormal, a contact of the electric limiting stopper is triggered to alarm through an upper limiting block and a lower limiting block, so that on-site operating personnel can find out and handle related abnormal situations.
Description
Technical field
The utility model relates to hydraulic brake, more particularly, relates to a kind of hydraulic brake failure alarm device.
Background technique
At present; scene need to be used hydraulic brake to carry out the place of work and safety protection; as travelling crane truck running mechanism, its hydraulic brake using as shown in Figure 1: it comprise Brake drum 1, brake shoe 2, connecting rod 3, moment adjusting nut 4, brake spring 5, hydraulic driver 6, etc. move back apart from critical pieces such as connecting rod 7, brake lever 9, hydraulic push rods 9.
In actual use, the adjustment while initially installing due to hydraulic brake is improper, or in normal production due to the wearing and tearing of break braking plate and the vibrations of equipment, can cause the excessive or too small situation of break brake clearance.The generation of these situations can directly cause misfunctioning of brake.And existing Inspection and maintenance mode is, relies on plant maintenance personnel's direct inspection or rule of thumb judge the good no of break braking effect.But the in the situation that of failing to find (if not within the operating time) or error in judgement in time if there is plant maintenance personnel, the state of break can not be held, therefore there is certain potential safety hazard.
Model utility content
For the above-mentioned shortcoming existing in prior art, the purpose of this utility model is to provide a kind of hydraulic brake failure alarm device, can be to extremely monitoring and and alarm.
For achieving the above object, the utility model adopts following technological scheme:
This hydraulic brake failure alarm device, comprise and spacingly hit chi, for detection of spacing, hit the electric limiting device of chi and for receiving the alarm mechanism of electric limiting device output signal, spacing hitting on the brake lever that chi is fixedly arranged on hydraulic brake, electric limiting device is fixedly arranged on the brake spring shell of hydraulic brake, and the output terminal of electric limiting device is electrically connected to the input end of alarm mechanism.
The described spacing chi that hits is longitudinally fixedly arranged on brake lever, and its lower end one side is provided with a pair of limiting stopper of upper and lower positioned opposite, and described electric limiting device is laterally fixedly arranged on brake spring shell, and its one end contact is located between two limiting stoppers.
The described spacing chi that hits fixes by bolt and brake lever, and described electric limiting device fixes by bolt and brake spring shell.
Described alarm mechanism is voice guard, visual alarm or computer interface alarm.
In technique scheme, hydraulic brake failure alarm device of the present utility model comprises and spacingly hits chi, for detection of spacing, hits the electric limiting device of chi and for receiving the alarm mechanism of electric limiting device output signal, spacing hitting on the brake lever that chi is fixedly arranged on hydraulic brake, electric limiting device is fixedly arranged on the brake spring shell of hydraulic brake, and the output terminal of electric limiting device is electrically connected to the input end of alarm mechanism.At break, occur when abnormal, by upper and lower spacing contact that touches electric limiting device, report to the police, so that execute-in-place attendant can find and process relevant abnormalities immediately.
Accompanying drawing explanation
Fig. 1 is the structural representation of the hydraulic brake of prior art;
Fig. 2 is the scheme of installation of hydraulic brake failure alarm device of the present utility model;
Fig. 3 is hydraulic brake failure alarm device schematic side view of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, further illustrate the technical solution of the utility model.
According to existing hydraulic brake structural feature, find that the inefficacy of hydraulic brake directly shows in pretravel (seeing the D in Fig. 2) variation of hydraulic push rod 8.If pretravel lower than lower limit, represents that hydraulic brake clearance is excessive, can cause Brake drum to skid, braking distance is long or the situation such as braking failure; If pretravel higher than the upper limit, represents that break brake clearance is too small, can cause the situations such as Brake drum heating, braking plate inordinate wear or lock of controller.
According to this feature, designed hydraulic brake failure alarm device of the present utility model, its structure as shown in Figure 2 to 3, it mainly comprises and spacingly hits chi 10, for detection of spacing, hits the electric limiting device 11 of chi 10 and for receiving the alarm mechanism 12 of electric limiting device 11 output signals, spacing hitting on the brake lever 9 that chi 10 is fixedly arranged on hydraulic brake, electric limiting device 11 is fixedly arranged on brake spring 5 shells of hydraulic brake, and the output terminal of electric limiting device 11 is electrically connected to the input end of alarm mechanism 12.So, by spacing, hit the spacing of chi 10 and be adjusted in pretravel allowed band, when the pretravel of hydraulic push rod 8 below or above set allowed band time, promote the upper and lower action of brake lever 9, at this moment spacing 10 of the chis that hit that are arranged on brake lever 9 touch spacing warning, make on-the-spot Operation and Maintenance personnel find in time the abnormal conditions that break produces, confirm in time and process.
As an embodiment, the described spacing chi 10 that hits is longitudinally fixedly arranged on brake lever 9, its lower end one side is provided with a pair of limiting stopper 13 of upper and lower positioned opposite, described electric limiting device 11 is laterally fixedly arranged on brake spring 5 shells, its one end contact 14 is located between two limiting stoppers 13, the distance between two limiting stoppers 13 be limited the distance of positions from.
As another embodiment, the described spacing chi 10 that hits is to fix by bolt 15 and brake lever 9, and described electric limiting device 11 is to fix by bolt 15 and brake spring 5 shells.
In addition, described alarm mechanism 12 is voice guard, visual alarm or computer interface alarm, and the latter three's combination, after electric limiting device 11 triggers, is sent limit signal to alarm mechanism 12, carries out and alarm.
Compared with prior art, hydraulic brake failure alarm device of the present utility model has the following advantages:
1, in brake block normal wear or while wearing and tearing suddenly, can provide alarm signal, prevent from occurring because misfunctioning of brake causes fault and accident.
2, abnormal at break hydraulic push rod 8, when break cannot be opened, can provide alarm signal, prevent from cannot opening and causing Brake drum or brake shoe inordinate wear because of break.
When 3, or other reason bad in brake clearance adjustment causes gap abnormal, can provide alarm signal, prevent from occurring because misfunctioning of brake causes fault and accident.
In sum, adopt hydraulic brake failure alarm device of the present utility model, can be in the actual using process of hydraulic brake, the inefficacy that its emergency case is caused provides timely and effectively and reports to the police, and prevents accident or fault extension.
Those of ordinary skill in the art will be appreciated that, above embodiment is only for the utility model is described, and be not used as restriction of the present utility model, as long as within the scope of connotation of the present utility model, to the above embodiment's variation, modification, all will drop within the scope of claims of the present utility model.
