Problems solved by technology
According to the theory known in the industry, when the oil temperature is above 100°C, the executive parts that are connected to the hydraulic circuit of the reversing valve, such as the aforementioned hydraulic shears, demolition tools, road excavation tools, hydraulic picks, and wire hydraulic crimping Tools such as pliers, hydraulic tree pruning shears, etc. are often unable to work, and may even cause safety accidents, because the higher the temperature of the hydraulic oil, the greater the pressure of the hydraulic oil, which may cause the pipeline to burst if it is light, and cause the actuator parts to fail if it is serious. collapse (for example, the wire hydraulic crimping pliers burst); the second reason is that after arriving at the work site, two independent modules need to be assembled, for example, the low-pressure oil outlet joint of the second module The oil joint is matched and the high-pressure oil inlet joint of the second module is matched with the high-pressure oil outlet joint of the first module. Therefore, if the connection is not good, it will cause leakage, and the on-site operation is more troublesome; the third reason is that as a hydraulic power Station, the reversing valve (the patent is also called combined valve) is an important part between the oil pump and the executive parts. Whether its structure is reasonable or not directly affects the use effect of the whole system. Inspiration

The invention discloses a hydraulic power station structure and belongs to movable hydraulic power units for field operation. The hydraulic power station structure comprises a rack, an engine, a hydraulic oil container, a heat-radiating mechanism, an overflow valve, an oil pump and a reversing valve. The hydraulic power station structure is characterized in that the heat-radiating mechanism comprises a fan casing, a fan and a radiator, and the oil pump is connected with an engine shaft; the reversing valve comprises a valve body, an operating-oil outgoing port an operating-oil returning port, an oil drainage port, an overflowing port, a valve spool and a reversing-valve operating handle, a valve-body longitudinal oil duct is formed in the valve body, the upper end of the valve-body longitudinal oil duct forms an oil-outlet opening of the valve-body longitudinal oil duct, the middle portion of the same forms an oil-feeding duct of the oil pump, and the lower end of the same forms an oil-return opening of the valve-body longitudinal oil duct; the valve spool is arranged in a valve spool cavity of the valve body, a pressure-relief hole is formed in the valve spool, and the reversing-valve operating handle is fixed together with the valve spool. By the arrangement, executing components connected between the operating-oil outgoing port and the operating-oil returning port can be durably and stably operated; reliability of oil supply by the oil pump to the reversing valve is guaranteed; operating efficiency is improved, and the engine is protected.
Description
technical field [0001] The invention belongs to the technical field of mobile hydraulic drive power devices for field operations, and is applied to industries such as roads, municipal bridges, expressways, tap water, telecommunications, electric power, railways, airports, ports, public security fire protection, landscaping, etc. power source. Background technique [0002] Hydraulic shears, hydraulic chain saws and various demolition tools for emergency relief, road excavation tools for municipal facilities and road and bridge maintenance, such as hydraulic picks and various straightening tools (for straightening bridge guardrails or highway guardrails) , The wire hydraulic crimping pliers used to connect the wires for the construction and repair of power lines and the hydraulic tree pruning shears used for tree trimming for landscaping, etc., must be powered by the hydraulic power station, and the hydraulic power station is required It has the characteristics of good workin...
