Description

Technical Field

[0001] This utility model relates to the field of hydraulic transmission equipment technology, and in particular to a multi-point output synchronous pump. Background Technology

[0002] Existing methods for controlling and linking multiple hydraulic components primarily employ mechanical linkage, flow distributors, displacement sensors, and hydraulic valve control. Among these:

[0003] (1) Mechanical linkage: Mechanical linkage is a way to achieve synchronization through physical connection. In this system, multiple hydraulic cylinders are connected to each other through mechanical components (such as synchronizing rods or gear systems). The physical connection ensures that the displacement of each cylinder is completely consistent when the cylinder moves. This method is usually used in scenarios where the synchronization accuracy requirement is not high and is suitable for scenarios with simple structure and low cost.

[0004] (2) Flow distributor: The flow distributor distributes the flow evenly to each hydraulic cylinder. By adjusting the settings of the distributor, it can be ensured that each hydraulic cylinder receives the same flow, thereby achieving synchronization. This method is usually used in parallel hydraulic systems, for example, when multiple hydraulic cylinders work together to lift heavy objects, the load of each output control point is the same when applied.

[0005] (3) Displacement sensor: When high-precision synchronization is required, position sensors and feedback control systems can be used. Each hydraulic cylinder is equipped with a position sensor to detect real-time displacement and transmit this data to the controller through the feedback control system. The controller fine-tunes the hydraulic valves according to the feedback data to ensure that the movement of each hydraulic cylinder remains synchronized. The advantage of this method is that it can achieve extremely high synchronization accuracy through real-time feedback and can adapt to dynamic changes in load. The disadvantage is that the system is highly complex, relies on electronic components, and has high technical requirements for installation, debugging and maintenance.

[0006] (4) Hydraulic valve control: Flow divider valve, in the hydraulic system, the flow divider valve can distribute the flow of a single oil source evenly or proportionally to multiple actuators according to demand. It is suitable for the synchronous control of multiple hydraulic cylinders. By accurately controlling the flow distribution, it ensures that each hydraulic cylinder maintains the same speed; Proportional valve, these precision valves can accurately adjust the flow and pressure of hydraulic oil, and combined with electronic signal input, achieve more accurate synchronization. They are usually used in conjunction with sensors and control systems to adjust the action of each hydraulic cylinder in real time. The disadvantages of hydraulic valve control are that it is relatively complex, requires the use of electrical sensors, has a short service life, and is prone to leakage accidents.

[0007] Based on this, this application provides a multi-point output synchronous pump. Utility Model Content

[0008] To solve the above-mentioned technical problems, this utility model provides a multi-point output synchronous pump, comprising:

[0009] Base;

[0010] A drive shaft, which is slidably mounted on a base;

[0011] A connecting plate is located above the base and is fixedly connected to the upper end of the drive shaft.

[0012] Multiple driven mechanisms are fixed on the base, and the driving ends of the multiple driven mechanisms are all fixedly connected to the connecting plate.

[0013] An active drive mechanism is connected to a drive shaft to drive the drive shaft to move.

[0014] In some embodiments, the plurality of driven mechanisms are evenly or unevenly distributed around the drive shaft.

[0015] In some embodiments, the upper end of the drive shaft is fixedly connected to the connecting plate by screws.

[0016] In some embodiments, the drive ends of the plurality of driven mechanisms are all fixedly connected to the connecting plate by screws.

[0019] Compared with existing technologies, the multi-point output synchronous pump provided in this application uses an active drive mechanism to drive a drive shaft, which in turn drives a connecting plate. This, in turn, causes multiple driven mechanisms to move synchronously. Simultaneously, corresponding external hydraulic cylinders independently connected to these driven mechanisms move synchronously, achieving precise multi-point output control and comprehensive control of various loads. Furthermore, this output synchronous pump has a simple structure, is easy to install and maintain, and is suitable for various driving forces, including mechanical and hydraulic forces, making it applicable to a wider range of scenarios and more comprehensive applications.

[0023] To facilitate understanding of the structure and operation of this utility model, the following description, in conjunction with the accompanying drawings and optimized embodiments, provides a more comprehensive and detailed account of the utility model. However, the scope of protection of this utility model is not limited to the specific embodiments described below. It should be noted that, without affecting the effectiveness of use, the structural features and component dimensions, connection methods, and device sizes in the embodiments of this utility model can be changed.

[0025] like Figure 1 , Figure 2 As shown, the multi-point output synchronous pump provided by this utility model includes:

[0026] Base 1;

[0027] Drive shaft 2, which is slidably mounted on base 1;

[0028] Connecting plate 3, which is located above base 1 and is fixedly connected to the upper end of drive shaft 2;

[0029] Multiple driven mechanisms 4 are fixed on the base 1, and the driving ends of the multiple driven mechanisms 4 are all fixedly connected to the connecting plate 3.

[0030] An active drive mechanism (not shown in the figure) is connected to the drive shaft 2 and is used to drive the drive shaft 2 to move.

[0031] In the above embodiment, the output synchronous pump drives the drive shaft 2 to move via an active drive mechanism. The drive shaft 2 then drives the connecting plate 3 to move, which in turn drives multiple driven drive mechanisms 4 to move synchronously. At this time, the corresponding external hydraulic cylinders 5, which are independently connected to the multiple driven drive mechanisms 4, move synchronously, thus realizing precise control of multi-point output and comprehensive control of various loads of the output synchronous pump. Moreover, the output synchronous pump has a simple structure, is easy to install and maintain, and is suitable for various driving forces such as mechanical force drive and hydraulic force drive, making it more widely applicable and comprehensive.

[0032] The plurality of driven mechanisms 4 are either driven hydraulic cylinders or driven piston cylinders. The plurality of driven mechanisms 4 are evenly or unevenly distributed around the drive shaft 2. The drive ends of the plurality of driven mechanisms 4 are fixedly connected to the connecting plate 3 by screws. Each driven mechanism 4 is externally connected to a hydraulic cylinder for independently controlling the action of the corresponding external hydraulic cylinder 5.

[0033] In this embodiment, it is assumed that there are four driven mechanisms 4, namely a, b, c, and d, and the external hydraulic cylinders 5 connected to the driven mechanisms 4 correspond to A, B, C, and D respectively. Therefore, the output synchronous pump has three operating modes, such as... Figure 2 As shown, the details are as follows:

[0034] ① When the cylinder diameter and flow rate of external hydraulic cylinders 5A, B, C, and D are equal, and the cylinder diameter and flow rate of driven mechanisms 4a, b, c, and d are equal, the synchronous lifting operation of external hydraulic cylinders 5A, B, C, and D can be controlled by drive shaft 2. That is, when drive shaft 2 moves, multiple chambers of driven mechanisms 4a, b, c, and d work simultaneously, and the output flow rate is equal, thereby controlling the synchronous operation of external hydraulic cylinders 5A, B, C, and D. This operating principle is often used for the synchronous lifting of cylinders in lifting platforms.

[0035] ② When the cylinder diameter and flow rate of external hydraulic cylinders 5A, B, C, and D are equal, the linkage of external hydraulic cylinders 5A, B, C, and D can be controlled by controlling the cylinder diameter and flow rate of driven mechanisms 4a, b, c, and d to be in a certain proportion. Since the cylinder diameter and flow rate of driven mechanisms 4a, b, c, and d are inconsistent, the extension and retraction lengths of the cylinders are different during operation, which can then control the different operating angles of external hydraulic cylinders 5A, B, C, and D. This operating principle is often used in lifting and traversing synchronous linkage devices.

[0036] ③ When the cylinder diameter and flow rate of external hydraulic cylinders 5A, B, C, and D are in a certain proportion, and the cylinder diameter and flow rate of driven mechanisms 4a, b, c, and d are equal, the drive shaft 2 controls the flow output of each chamber of driven mechanisms 4a, b, c, and d, which can drive the linkage of external hydraulic cylinders 5A, B, C, and D. This operating principle is often used to control tilting devices.

[0037] In this embodiment, under the driving force of the active drive mechanism, the drive shaft 2 reciprocates, and through the connecting plate 3, it can drive multiple driven mechanisms 4 to move, thereby achieving the purpose of synchronization at each point. Since the driven mechanisms 4 are individually connected to each external system (i.e., Aa, Bb, Cc, and Dd are each an independent internal circulation hydraulic system), the load of each driven mechanism 4 can be different, and they can move synchronously. That is, the multi-point output synchronous pump provided in this application solves the technical problems existing in the prior art.

[0038] In some embodiments, the upper end of the drive shaft 2 is fixedly connected to the connecting plate 3 by screws.

[0039] In the above embodiment, the upper end of the drive shaft 2 is fixedly connected to the connecting plate 3 by screws, which ensures the reliability of the connection between the drive shaft 2 and the connecting plate 3.

[0040] The multi-point output synchronous pump provided by this utility model has been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the core idea of ​​this utility model. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
