According to the hydraulic controllable braking device disclosed by the invention, the braking reliability of a conveyer is improved, the service life of the conveyer is prolonged, and the use and maintenance costs of the conveyer are reduced.
Description
Technical field
The present invention relates to be applied to the Idler Technology field of this material transfer equipment of belt conveyer, make the belt conveyer carrying roller possess controllable brake, rotating operation monitoring, Combination properties such as fault alarm, thereby the reliable stopping brake of realization belt conveyer.
Background technology
Belt conveyer is mainly by carrying roller, and support, compositions such as transfer drive, carrying roller are one of main composition parts of belt conveyer, use the most extensive.Because belt speed and freight volume is different, the oad of carrying roller is different.Carrying roller kind commonly used has: impact idler, parallel roll, aligning carrier roller etc.
At present, the belt conveyer carrying roller mainly contains following kind both at home and abroad
1. parallel roll
Be used for the return leg support belt
2. impact idler:
Be installed in material feeding section below, reduce the suffered impact of load-transfer device
3. aligning carrier roller:
Be provided for adjusting belt deflection
But above-mentioned all kinds of carrying rollers itself all do not have braking function, and conveyer also needs to add in addition special brake equipment and carries out the braking of equipment.This concentrates braking force, can't realize the controllable brake of belt conveyer, has reduced the safety of equipment.
Summary of the invention
The purpose of this invention is to provide a kind of hydraulic pressure controllable brake device that can realize that moment is controlled.
The objective of the invention is to realize through following technical scheme:
Hydraulic pressure controllable brake device of the present invention comprises carrying roller, and the carrying roller both sides are provided with Hydraulic Pump, and the main shaft of carrying roller is connected through key with Hydraulic Pump, and Hydraulic Pump is connected with Hydraulic Station, and Hydraulic Station is provided with hydraulic control system, and hydraulic control system is provided with electro-hydraulic proportional valve.
Technical scheme by the invention described above provides can be found out; Hydraulic control system realizes the controllable brake to carrying roller through the control electro-hydraulic proportional valve; This device has improved the braking reliability of conveyer, has prolonged the service life of conveyer, has reduced the operation and maintenance expense of conveyer.
Description of drawings
Fig. 1 is a hydraulic pressure controllable brake apparatus structure scheme drawing;
Fig. 2 is a hydraulic pressure controllable brake device hydraulic control system structural representation.
The specific embodiment
Hydraulic pressure controllable brake device of the present invention, the specific embodiment that it is preferable such as Fig. 1, shown in Figure 2, hydraulic pressure controllable brake device; Comprise carrying roller 1; Carrying roller 1 both sides are provided with Hydraulic Pump 2, and the main shaft of carrying roller 1 and Hydraulic Pump 2 are connected through key, and Hydraulic Pump 2 is connected with Hydraulic Station 3; Hydraulic Station 3 is provided with hydraulic control system 6, and hydraulic control system is provided with electro-hydraulic proportional valve 7.
Hydraulic control system 6 realizes the adjustment of lock torque through control electro-hydraulic proportional valve 7 modulated pressure pump discharge oil pressure.A hydraulic control system can be connected with many groups hydraulic pressure controllable brake device, realizes the concentrated control of braking of many groups.
Hydraulic Pump 2 is provided with flow monitoring device 4 and pressure monitoring device 5, is used to monitor the flow and the inlet and outlet pressure of hydraulic oil in the Hydraulic Pump, makes carrying roller 1 have the monitoring running state function, carrying roller malfunction monitoring when realizing normal the operation;
Flow monitoring device 4 is connected accident warning device with pressure monitoring device 5, when monitoring carrying roller operation mal, can send alerting signal.
Hydraulic pressure controllable brake device of the present invention is mainly used under downward belt conveyor and the long belt conveyor and transports in the section, has improved the reliability of conveyer, has prolonged the service life of conveyer, and it has following inventive point:
Electro-hydraulic proportional valve is arranged in the hydraulic control system, realize that through the control electro-hydraulic proportional valve Hydraulic Pump exports the automatic compensation of oil pressure, have anti-" locking " function, improved the deceleration and stopping performance of carrying roller, prolonged the life-span of conveyer.
Through hydraulic control system control, can make carrying roller convenient switching between common carrying roller function and controllable brake function.
Carrying roller has the monitoring running state function, carrying roller malfunction monitoring when realizing normal the operation.
Adopt a hydraulic efficiency pressure system can realize controllable brake to many groups hydraulic pressure controllable brake carrier roller.
Below in conjunction with accompanying drawing principle of work of the present invention is further specified:
When carrying roller normally moves; With the carrying roller operation, hydraulic control system control electro-hydraulic proportional valve equates the import and export oil pressure of Hydraulic Pump to Hydraulic Pump under the carrying roller effect; This moment, the spin velocity of Hydraulic Pump blade was identical with the spin velocity of carrying roller; Thereby make the normal rotary work state of carrying roller, promptly carrying roller moves according to common carrying roller function
Carrying roller needs glancing impact; The pressure of hydraulic control system modulated pressure station electro-hydraulic proportional valve makes hydraulic pressure delivery side of pump oil pressure greater than the import oil pressure, and oil inlet and outlet produces pressure reduction; Thereby the rotating speed of Hydraulic Pump inner gear is reduced; Along with the increase of electro-hydraulic proportional valve control presssure, the rotating speed of Hydraulic Pump reduces gradually, realizes the controllable brake to carrying roller.
Accident warning device is monitored the state of kinematic motion of carrying roller, when monitoring carrying roller operation mal, can send alerting signal.
The invention has the beneficial effects as follows:
Carrying roller has the controllable brake performance, has improved the reliability of conveyer, has prolonged the service life of conveyer.
Reduced the operation and maintenance expense of conveyer.
Reduce the replacing amount of post workman and carrying roller, reduced investment.
The above; Be merely the preferable specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any technical personnel of being familiar with the present technique field is in the technical scope that the present invention discloses; The variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.
