Abstract
The utility model discloses a hydraulic brake. The utility model aims to provide an improved hydraulic brake. The hydraulic brake comprises a brake bracket and a lining plate, and is characterized in that a travel switch is arranged on the brake bracket; a collision block is arranged on the lining plate; the sensor is connected with the collision block through the bracket; and the pressure sensor is arranged between the lining plate and a brake shoe. The hydraulic brake is mainly used for braking an elevating winch for mining.
Description
Technical field
The utility model relates to a kind of break, relates in particular to a kind of hydraulic brake.
Background technique
The break of conventional construction is not installed the tired protective gear of dish spring, brake block abrasion protective gear, gap protection device, does not have the on-line monitoring positive pressure.
Existing problems: 1, after the break operating time length, brake block abrasion, positive pressure descends, and braking moment is not enough, if untimely adjustment brake clearance can produce potential safety hazard.2, the tired positive pressure of break operating time long back dish spring descends, and braking moment is not enough, if untimely replacing dish spring can produce potential safety hazard.3, brake shoe and brake disc distance is uncertain, and it is big that distance becomes, and time lag is elongated, and stopping distance is long, and braking force also diminishes.4, can't directly monitor positive pressure.
Summary of the invention
The purpose of the utility model is to provide a kind of improved hydraulic brake, to overcome above-mentioned deficiency.
For realizing above-mentioned purpose; The technical solution of the utility model is: a kind of hydraulic brake, comprise brake support frame and liner plate, and it is characterized in that: on the described brake support frame 3; Position limit switch 1,14 is installed; On the liner plate 6, collision block 2,10, sensor 12 is installed links to each other with collision block 10 through support 11, pressure transducer 8 is installed between liner plate 6 and the brake shoe 7.
The beneficial effect of the utility model is:
Break has been installed dish spring fatigue, brake block abrasion device, gap protection device, and one or more pieces pressure transducers are installed between liner plate and the brake shoe.
1, the tired protection unit of dish spring: after the fatigue failure of dish spring, signal is sent in corresponding position limit switch action; 2, brake block abrasion protective gear: brake block abrasion to a certain degree, signal is sent in the action of corresponding position limit switch; 3, gap protection device: brake shoe and brake disc distance are excessive, and sensor sends signal; 4, one or more pieces pressure transducers, on-line monitoring positive pressure are installed between liner plate and the brake shoe.5, pressure transducer is installed between liner plate and the brake shoe and changes conveniently.

Accompanying drawing is the structural representation of the utility model.
Among the figure: 1, position limit switch, 2, collision block, 3, brake support frame, 4, oil cylinder, 5, piston, 6, liner plate, 7, brake shoe, 8, pressure transducer, 9, the dish spring, 10, collision block, 11, support, 12, sensor, 13, brake disc, 14, position limit switch.
Embodiment
Below in conjunction with accompanying drawing the utility model and embodiment thereof are done further explain.
Referring to accompanying drawing; The utility model comprises brake support frame and liner plate; It is characterized in that: on the described brake support frame 3, position limit switch 1,14 is installed, on the liner plate 6; Collision block 2,10, sensor 12 is installed links to each other with collision block 10 through support 11, pressure transducer 8 is installed between liner plate 6 and the brake shoe 7.
The basic principle of this hydraulic brake is that hydraulic pressure declutches, the spring force braking, and positive pressure is through the pressure transducer on-line monitoring and have brake block abrasion protective gear, the tired protective gear of dish spring, gap protection device.
The brake block abrasion protective gear is made up of position limit switch 1, collision block 2, and the tired protective gear of dish spring is formed with collision block 10 by position limit switch 14 is installed, and the gap protection device is made up of sensor 12 and support 11.
The working procedure explanation: when pressure oil got between oil cylinder 4 and the piston 5, piston 5 drove liner plate 6 and retreats, and brake shoe 7 is realized declutching away from brake disc 13.After oil cylinder 4 releases, under dish spring 9 active forces, liner plate 6 is pressed onto brake shoe 7 and realizes braking on the brake disc 13.After oil cylinder 4 releases, under dish spring 9 active forces, liner plate 6 is pressed onto brake shoe 7 on the brake disc 13, if brake shoe 7 wearing and tearing surpass 2mm, and the collision block 2 touching position limit switches 1 on the liner plate 6, position limit switch 1 sends signal.If after 9 fatigue failures of dish spring, pressure oil gets between oil cylinder 4 and the piston 5, and piston 5 drives liner plate 6 and retreats, the collision block 10 on the liner plate 6, and touching position limit switch 14, position limit switch 1 sends signal.The distance of sensor 12 real-time monitoring brake shoes 7 and brake disc 13 after brake disc 13 long-term works, can produce beat, and brake shoe 7 can change with the distance of brake disc 13, in the time of between surpassing necessarily, sends signal.The positive pressure of 7 pairs of brake discs 13 of brake shoe when pressure is less than normal, is sent cue during the braking of pressure transducer on-line monitoring.
The relation explanation is installed: position limit switch 1,14 is installed on brake support frame 3; Collision block 2,10, support 11, sensor 12 are installed on the liner plate 6; Pressure transducer 8 is installed between liner plate 6 and the brake shoe 7.
