Abstract
The utility model discloses an energy-saving valve in a hydraulic braking system. The energy-saving valve comprises a hydraulic oil tank, a power unit, a one-way valve, a proportional flow valve, a reversing valve, a pressure relay and a brake, wherein an oil supply path between the reversing valve and the brake is provided with an energy storage device. By using the energy-saving valve, the oil supply frequency of the power unit is greatly reduced, the power consumption of a storage battery is reduced, and the effects of energy conservation and reduction emission are achieved as a whole. The stability is greatly improved during travel starting and braking.
Description
Technical field:
The utility model relates to a kind of a kind of full electric type aerial lift device that relates to, the energy-conservation valve in particularly a kind of hydraulic brake system.
Background technology:
Form by hydraulic reservoir 1, power unit 2, check valve 3, proportional flow control valve 4, change-over valve 5, pressure relay 6, drg 7, energy storage 8 at full electric type aerial platform hydraulic brake system.The electrodynamic type high-altitude operation platform is from fuel tank 1 oil suction by power unit 2 when work; Produce operation pressure; Proportional flow control valve 4 its pressure oils of energising back flow to change-over valve 5 through check valve 3; When change-over valve 5 energising, pressure oil leads to drg 7, drg 7 open and feedback pressure signal to pressure relay 6.The pressure that pressure relay 6 detects has surpassed the pressure that drg is opened, and power unit 2 outages come pressurize with check valve 3.When the pressure that detects when pressure relay 6 was lower than the pressure that drg opens, power unit 2 energisings continued to give drg 7 to supply pressure oils.Power unit 2 outages when walking stops, change-over valve 5 outages, the pressure oil of drg 7 leads to the fuel tank pressure release.
The major defect of prior art: electrodynamic type aerial platform travel time system dwell time of being expert at itself is very of short duration; The frequency of power unit 2 fuel feeding is too high; And all-electric aerial platform is by storage battery energy to be provided, so the consumption of current of storage battery is very big, its loss work-hours; Because of not having shock absorber or shock absorption device, when product starts and stops in walking, exist and impact big phenomenon.
Summary of the invention
The utility model solves the prior art deficiency and a kind of power consumption that reduces storage battery that has is provided; The energy-conservation valve of raising in the hydraulic brake system of walking startup and glancing impact stationarity.
Energy-conservation valve in a kind of hydraulic brake system comprises hydraulic reservoir, power unit, check valve, proportional flow control valve, change-over valve, pressure relay and drg, on the fuel feeding road between said change-over valve and the said drg energy storage is installed.
Adopt said structure, the advantage of the utility model is: the frequency of power unit fuel feeding reduces greatly, reduces the power consumption of storage battery, has reached the effect of energy-saving and emission-reduction generally.Be greatly improved in walking startup and glancing impact stationarity.
Description of drawings
Fig. 1 is the hydraulic schematic diagram of existing hydraulic brake system;
Fig. 2 is the hydraulic schematic diagram of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done detailed description further.
As shown in Figure 2, the utility model is in order to solve the problems of the technologies described above, and the utility model has added an energy storage 8 on change-over valve 5 and drg 7 fuel feeding roads.When power unit 2 started, system gave each operating valve piece fuel feeding and gives energy storage 8 makeup energy deposits, makes capable energy storage 8 long-time pressurize and fuel feeding states; When power unit 2 quit work, the energy in the energy storage 8 can add in the brake system, can make in the brake system work of treatment, and also more steady when walking starts and stops.
Claims (1)
1. the energy-conservation valve in the hydraulic brake system; Comprise hydraulic reservoir, power unit, check valve, proportional flow control valve, change-over valve, pressure relay and drg, it is characterized in that: on the fuel feeding road between said change-over valve and the said drg energy storage is installed.
