Abstract
The utility model discloses a hydraulic controllable braking device which comprises a carrier roller. Both sides of the carrier roller are provided with hydraulic pumps. A spindle of the carrier roller is connected with the hydraulic pumps through keys. The hydraulic pumps are connected with a hydraulic station. The hydraulic station is provided with a hydraulic control system. The hydraulic control system is provided with an electro-hydraulic proportional valve. The hydraulic control system realizes the controllable brake of the carrier roller through controlling the electro-hydraulic proportional valve. Due to the adoption of the hydraulic controllable braking device, the braking reliability of a conveyor is improved, the service life of the conveyor is prolonged and the using and maintenance cost of the conveyor is reduced.
Description
Technical field
The utility model relates to the Idler Technology field that is applied to this material transfer equipment of belt conveyer, makes 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, are most widely used.Because belt speed and freight volume is different, the oad difference of carrying roller.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 special brake equipment in addition 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.
The utility model content
The purpose of this utility model provides a kind of hydraulic pressure controllable brake device that can realize that moment is controlled.
The purpose of this utility model is achieved through the following technical solutions:
Hydraulic pressure controllable brake device of the present utility model comprises carrying roller, and the carrying roller both sides are provided with Hydraulic Pump, and the main shaft of carrying roller is connected by 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.
The technical scheme that is provided by above-mentioned the utility model as can be seen, hydraulic control system realizes controllable brake to carrying roller by 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 utility model, its preferable specific embodiment as shown in Figure 1 and 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 by 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 by 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, can send alerting signal when monitoring carrying roller operation mal.
Hydraulic pressure controllable brake device of the present utility model 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 innovative point:
Electro-hydraulic proportional valve is arranged in the hydraulic control system, realize that by 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.
By 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 utility model is further specified:
When carrying roller normally moves, Hydraulic Pump moves with carrying roller under the carrying roller effect, hydraulic control system control electro-hydraulic proportional valve, the import and export oil pressure of Hydraulic Pump is equated, 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, make hydraulic pressure delivery side of pump oil pressure greater than the import oil pressure, 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, can send alerting signal when monitoring carrying roller operation mal.
The beneficial effects of the utility model are:
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; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
