Description

Technical Field

[0001] This invention relates to the field of engineering machinery technology, specifically to a loading boom stabilization module, hydraulic system, and method of use. Background Technology

[0002] Loaders are widely used in earthmoving, mining, and sand and gravel quarrying operations, primarily performing tasks such as material loading, lifting, and full-load transfer. When a loader is fully loaded and transporting materials on bumpy or uneven roads, the boom cylinder's rodless chamber (boom rodless chamber) forms a closed, rigid cavity. The impact load from road undulations is directly transmitted to the bucket, easily causing material to spill and leak from the bucket, reducing material transfer efficiency. At the same time, continuous vibration significantly worsens the operator's working environment, leading to fatigue during prolonged operation and poor overall driving comfort.

[0003] Currently, the industry uses accumulator-type stabilization modules for shock absorption, but existing stabilization modules have obvious defects: the pressure of the accumulator and the boom rodless chamber cannot be automatically balanced, resulting in large impact vibrations when activated; the valve group is driven by the pressure of the boom rodless chamber, and the pressure fluctuations during bumps will affect the stable operation of the buffer function; there is no throttling adjustment structure, so the buffering effect cannot be adapted to different models; the oil inlet lacks a check valve, and the pressure fluctuations in the main oil circuit will disrupt the working pressure of the accumulator, resulting in rapid decay of the buffering performance.

[0004] The existing solutions are insufficient in overall performance and cannot meet the usage requirements such as preventing spillage during material handling, driving comfort, and compatibility with multiple machine models. Therefore, there is an urgent need to design a loader boom stabilization module with optimized structure and more stable working performance, as well as a matching hydraulic system. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a loading boom stabilization module, hydraulic system and usage method, which eliminates the hydraulic shock at the moment the stabilization module is opened, avoids the interference of pressure fluctuation in the boom rodless chamber, and improves the stability of material transfer on bumpy roads and driving comfort.

[0006] The present invention is achieved by the following technical solution: a loading boom stabilization module, comprising a dynamic balance valve, a boom stabilization valve, a pilot control valve, an energy storage unit, a one-way conduction device, and a flow regulation device; The dynamic balance valve has two control terminals connected to the energy storage unit and the rodless chamber of the working cylinder, respectively. It switches the working position by comparing the oil pressure of the energy storage unit and the rodless chamber of the working cylinder, so as to fill or depressurize the energy storage unit. The boom stabilizing valve has an oil port on one side connected to the energy storage unit and an oil port on the other side connected to the dynamic balance valve and the rod-side and rodless-side chambers of the working cylinder. The working position is switched through the pilot control valve to achieve the boom stabilizing function. Pilot control valve, the hydraulic control end of which connects the pilot oil and the boom stabilizer valve, controls the opening or closing of the buffer oil circuit between the energy storage unit and the rodless chamber of the boom cylinder; The unidirectional conduction device is set in the module's working oil inlet passage to block the reverse disturbance of the main oil circuit pressure to the energy storage unit; A flow regulating device is connected in series between the energy storage unit and the boom stabilizing valve to regulate the oil intake and discharge rate of the energy storage unit.

[0007] Furthermore, the dynamic balancing valve is a three-position three-way hydraulic control directional valve, with damping devices provided at both hydraulic control ends.

[0008] The boom stabilizing valve is a two-position five-way hydraulically controlled directional valve.

[0009] The pilot control valve is a two-position three-way solenoid directional valve.

[0010] The one-way conduction device is a one-way valve that only allows the main system pressure oil to be supplied to the inside of the stabilization module.

[0011] The flow regulating device is an adjustable flow valve, which adjusts the flow rate of the buffer oil circuit by changing the throttling flow area.

[0012] The module integrates a working oil inlet, an accumulator interface, a pilot control oil inlet, a boom cylinder connection oil inlet, and a return oil inlet. The energy storage unit is externally connected to the accumulator interface.

[0013] A hydraulic system using a loading boom stabilization module, comprising any one of the above-mentioned loading boom stabilization modules, and further comprising a working pump, a pilot pump, a boom main directional valve, and a boom cylinder; The working pump provides pressurized oil to the loading boom stabilization module and connects the rod chamber and rodless chamber of the boom cylinder through the boom main directional valve; The boom main directional valve controls the lifting and lowering actions of the boom cylinder by switching the working position; The pilot pump, connected to the pilot control valve, provides pilot hydraulic oil to the loading boom stabilization module.

[0014] The boom main directional valve is a two-position four-way directional valve.

Transfer and buffering operation: The pilot control valve switches to open the buffer oil circuit, the energy storage unit acts as a hydraulic spring to absorb the impact of road bumps, and the flow regulation device adjusts the buffering response speed.

[0016] The present invention has the following advantages: 1.

The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] like Figure 1 The aforementioned loader boom stabilization module includes a dynamic balance valve, a boom stabilization valve, a pilot control valve, an energy storage unit, a one-way conduction device, and a flow regulating device; the six major components of this invention work together to form an integrated valve group, fully supporting all operating conditions of the loader, including lifting, static pressure holding, and bumpy transportation. The dynamic balance valve has two control ends connected to the energy storage unit and the rodless chamber of the working cylinder, respectively. It switches the working position by comparing the oil pressure of the energy storage unit and the rodless chamber of the working cylinder, thereby realizing the filling or depressurization of the energy storage unit. The dynamic balance valve is a hydraulically controlled valve. The control oil circuits at both ends collect the real-time oil pressure on the energy storage unit side and the rodless chamber of the boom cylinder, respectively. It autonomously switches the valve core position based on the pressure difference, dynamically balancing the oil pressure on both sides throughout the entire process, eliminating the pressure difference shock at the moment the buffer function is activated. The boom stabilizing valve has one port connected to the energy storage unit and the other port connected to the dynamic balance valve and the rod-side and rodless-side chambers of the working cylinder. The working position is switched via a pilot control valve to achieve boom stabilization. In its normal working position, the boom stabilizing valve isolates the energy storage unit from the cylinder oil circuit, ensuring the boom remains stationary and pressurized. After receiving a pilot control signal, the working position is switched, opening the buffer oil circuit between the energy storage unit and the rodless-side chamber of the boom cylinder, allowing the energy storage unit to act as a hydraulic spring to absorb the impact of road bumps, thereby achieving the stabilizing function of material transfer shock absorption and spill prevention. The pilot control valve connects the pilot oil and the hydraulic control end of the boom stabilizing valve. It controls the opening or closing of the buffer oil circuit between the energy storage unit and the rodless chamber of the boom cylinder. When the pilot control valve is energized, it outputs pilot control oil to drive the hydraulic control main directional valve to switch, connecting the energy storage unit and the buffer oil circuit of the rodless chamber of the boom cylinder, so that the stabilizing module can intervene in the buffer operation. The one-way flow device is set in the module working oil inlet passage to block the reverse disturbance of the main oil circuit pressure to the energy storage unit; the one-way flow device only allows the working pump pressure oil to flow into the module in one direction, blocks the reverse flow channel of the high pressure oil of the accumulator, isolates the load fluctuation of the main working pump and the instantaneous impact pressure from being transmitted to the energy storage unit, and stabilizes the preset working pressure of the accumulator. A flow regulating device, connected in series between the energy storage unit and the boom stabilizing valve, is used to regulate the oil intake and discharge rate of the energy storage unit. By adjusting the throttling flow cross-sectional area, the flow regulating device changes the oil flow rate, flexibly controlling the speed of oil intake and discharge from the energy storage unit to adapt to the shock absorption response requirements of loaders of different tonnages.

[0025] like Figure 1 The aforementioned boom stabilization module for loading equipment includes a dynamic balance valve, which is a three-position, three-way hydraulically controlled directional valve with damping devices on both hydraulic control ends. The three working positions of the dynamic balance valve correspond to three operating conditions: filling, shut-off, and depressurization. It can automatically complete filling and depressurization based on the pressure difference between the energy storage unit and the rodless chamber of the boom cylinder, achieving dynamic pressure balance on both sides. When the energy storage pressure is too low, it automatically opens the filling passage; when the energy storage pressure is too high, it automatically opens the depressurization passage, without the need for additional electronically controlled valve intervention. Furthermore, the two hydraulic control ends are respectively matched with damping I5 and damping II7. The damping can buffer instantaneous pressure spikes caused by road bumps, filter high-frequency oil pressure fluctuations, prevent frequent valve core vibration and erroneous reversal due to impact, and improve the smoothness of valve core operation.

[0026] like Figure 1 The aforementioned loading boom stabilization module includes a boom stabilization valve that is a two-position five-way hydraulic directional valve.

[0027] like Figure 1 The boom stabilization module described above uses a two-position three-way solenoid directional valve as its pilot control valve. The pilot control valve of this invention is directly connected to the independent pilot pump oil source of the entire machine. Upon energization, it outputs pilot pressure oil to drive the boom stabilization valve to switch directions. The driving force is taken from the independent pilot oil circuit, independent of the rodless chamber pressure of the boom cylinder, completely avoiding interference from cylinder pressure fluctuations caused by road bumps, resulting in more stable start-stop operation.

[0028] like Figure 1The aforementioned boom stabilization module for loading equipment includes a one-way valve that allows only main system pressurized oil to be supplied to the stabilization module. This one-way valve is installed on the main working oil inlet channel (P port) of the stabilization module, forming a one-way oil flow barrier. In the forward flow, the high-pressure oil output from the working pump flows smoothly into the module, providing a filling source for the dynamic balance valve. In the reverse flow, it completely blocks the backflow of high-pressure oil from the accumulator unit and the rodless chamber pressurized oil of the boom cylinder to the main working pump circuit. This prevents pressure fluctuations in the main oil circuit and the impact of the lifting load from being transmitted to the accumulator, stabilizing the accumulator's preset buffer working pressure and preventing long-term degradation of buffer performance. Furthermore, it prevents high-pressure oil from the accumulator from flowing back into and impacting the working pump, protecting the main pump components. Simultaneously, it ensures stable filling pressure of the dynamic balance valve, guaranteeing that the automatic pressure balancing logic between the accumulator and the boom cylinder is not interfered with by the main oil circuit.

[0029] like Figure 1 The aforementioned loader boom stabilization module includes an adjustable flow valve as the flow regulating device. The flow rate in the buffer oil circuit is adjusted by changing the throttling flow area. This adjustable flow valve is connected in series between the accumulator SP oil circuit and the boom stabilization valve. Rotating the throttling knob changes the oil flow cross-sectional area, adjusting the accumulator's oil intake and discharge speed. For small loaders, a smaller opening reduces buffering; for large loaders, a larger opening increases shock absorption response. A single module can be adapted to all loader models.

[0030] like Figure 1 The aforementioned boom stabilization module integrates a working oil inlet, an accumulator interface, a pilot control oil inlet, a boom cylinder connection oil inlet, and a return oil inlet. The energy storage unit is externally connected to the accumulator interface. The module of this invention features standardized oil inlets, including a working oil inlet (P inlet), an external accumulator connection (SP inlet), a pilot control oil inlet (PX inlet), a boom cylinder cavity connection (R / H inlet), and a return oil inlet (T inlet). The centralized oil inlet layout simplifies piping and wiring during assembly, reduces external oil pipes and joints, and lowers leakage risks and assembly costs.

[0031] like Figure 2 The hydraulic system shown uses a loading boom stabilization module, including a loading boom stabilization module, and also includes a working pump, a pilot pump, a boom main directional valve, and a boom cylinder; The working pump provides pressurized oil to the loading boom stabilization module and connects the rod chamber and rodless chamber of the boom cylinder through the boom main directional valve; The boom main directional valve controls the lifting and lowering actions of the boom cylinder by switching the working position; The pilot pump, connected to the pilot control valve, provides pilot hydraulic oil to the loading boom stabilization module.

[0032] The hydraulic system of the present invention is divided into two circuits: the main working oil circuit and the independent pilot control oil circuit. They are completely separated and do not interfere with each other. The working pump 14 is responsible for boom lifting and accumulator filling. The pilot pump 11 supplies the buffer function control oil source separately, eliminating the interference of boom load pressure on the buffer valve group from the source of the oil circuit. The working pump 11 is connected in parallel with the relief valve 12 to realize system overload protection. All returned oil is collected in the oil tank 13.

[0033] like Figure 2 The hydraulic system shown uses a loader boom stabilization module, wherein the boom main directional valve is a two-position four-way directional valve. The three working positions of the boom main directional valve 9 of this invention correspond to three working conditions: lowering, holding, and lifting. The middle position cuts off the oil supply to the rodless chamber of the boom cylinder, and in conjunction with the left position of the boom stabilization valve within the stabilization module, closes the oil circuit. This forms a complete sealed cavity in the rodless chamber of the boom cylinder, effectively controlling the amount of static settlement of the boom and meeting the operational specifications of the loader industry.

[0034] A method for using a loading boom stabilization module includes a loading boom stabilization module and a hydraulic system using the loading boom stabilization module, and further includes the following working conditions: Boom lifting operation: The working pump supplies oil to the boom cylinder, and the dynamic balance valve automatically matches the oil pressure of the accumulator unit and the rodless chamber of the boom cylinder. During the lifting operation, the dynamic balance valve automatically fills or drains oil according to the pressure difference on both sides, always keeping the pressure of the accumulator and the rodless chamber of the boom consistent. When the buffer function is activated, there is no pressure difference impact, eliminating boom vibration. When the boom is stationary and under pressure holding conditions: the boom main directional valve is in the neutral position to relieve pressure, the pilot control valve cuts off the buffer oil circuit, and the rodless chamber of the boom cylinder is closed to achieve pressure holding and settling control; during the pressure holding condition, the cylinder oil circuit is doubly closed to prevent oil leakage and avoid the boom from sinking on its own. In buffering mode: the pilot control valve switches to open the buffer oil circuit, and the accumulator unit acts as a hydraulic spring to absorb the impact of road bumps. The flow regulating device adjusts the buffering response speed. During buffering mode, the accumulator acts as a hydraulic spring to absorb the changes in cylinder volume caused by road bumps. The adjustable flow valve matches the machine model to adjust the buffering speed, reduce material spillage from the bucket, and improve the comfort of the cab operator.

[0035] Combination Figure 1 and Figure 2 The working principle of the present invention will be described in detail below: During boom lifting operation: When the boom main directional valve 9 switches to the right position, the hydraulic fluid from the working pump 14 enters the rodless chamber of the boom cylinder 10 through the boom main directional valve 9, causing the boom cylinder to extend and perform a lifting action. Simultaneously, the hydraulic fluid from the working pump 14 enters the P port of the stabilization module and then enters the inlet of the dynamic balance valve 1 through the check valve 6. The left end of the dynamic balance valve 1 receives the charging pressure of the accumulator 8, and the right end receives the pressure of the rodless chamber of the boom cylinder 10. If the pressure of the accumulator 8 is less than the pressure of the rodless chamber of the boom cylinder 10, the dynamic balance valve 1 switches to the right position, and the working pump 14 charges the accumulator. If the pressure of the accumulator 8 is greater than the pressure of the rodless chamber of the boom cylinder 10, the dynamic balance valve 1 switches to the left position, and the excess pressure from the accumulator 8 is released to the T port through the adjustable flow valve 4, the boom stabilization valve 3, and the dynamic balance valve 1.

[0036] When the boom stops lifting: At this time, the boom main directional valve 9 is switched to the neutral position, the boom stabilizing valve 3 is in the left position, and the rodless chamber oil of the boom cylinder 10, the boom main directional valve 9, and the boom stabilizing valve 3 are all in the closed state. At this time, the boom cylinder 10 achieves pressure maintenance to ensure that the settlement amount does not exceed the standard when the boom is stationary.

[0037] When the boom stabilization module is activated When the loader is transporting materials on uneven roads, the pilot control valve 2 is energized and switches to the right position. The pilot oil from the pilot pump 11 enters the control chamber of the boom stabilizer valve 3 through the pilot control valve 2. The boom stabilizer valve 3 then switches to the right position. At this time, the rodless chamber of the boom cylinder 10 is connected to the accumulator 8. The accumulator 8 acts as a hydraulic spring, stabilizing the pressure in the rodless chamber of the boom cylinder and ensuring stable pressure. Because an adjustable flow valve 4 is provided between the rodless chamber of the boom cylinder 10 and the accumulator 8, the intake and discharge of oil in the accumulator can be adjusted by adjusting the adjustable flow valve 4, thus making the stabilization module adjustable.

[0038] This invention discloses a loader boom stabilization module, hydraulic system, and method of use. The integrated stabilization module comprises a dynamic balance valve, a boom stabilization valve, a pilot control valve, an energy storage unit, a check valve, and an adjustable flow valve. The dynamic balance valve compares the oil pressure in the energy storage unit and the rodless chamber of the boom cylinder, automatically completing the accumulator's filling and depressurization to achieve dynamic pressure balance. An independent pilot oil circuit drives the boom stabilization valve to open and close the buffer oil circuit, unaffected by pressure fluctuations in the boom cylinder. A check valve at the oil inlet unidirectionally guides the main system pressure oil, isolating the accumulator from pressure disturbances in the main oil circuit. An adjustable flow valve connected in series in the energy storage oil circuit regulates the accumulator's oil intake and discharge rates. The entire machine is equipped with an independent working pump and a pilot pump, enabling three working conditions: automatic pressure adjustment during boom lifting, pressure maintenance and anti-settlement in the mid-position, and flexible buffering during bumpy transport. This addresses the needs of shock absorption and spill prevention, driver comfort, and compatibility with multiple machine models.
