Description

Technical Field

[0001] This utility model relates to the field of directional valve technology, and in particular to a safety directional valve device for a hydraulic integrated accumulator. Background Technology

[0002] The safety directional valve device of a hydraulic integrated accumulator is a hydraulic component that integrates a directional valve and an accumulator. The directional valve controls the flow of hydraulic fluid through the movement of its valve core, thereby reversing the direction of the actuator. The accumulator stores energy using gas compression and can replenish oil, stabilize pressure, and absorb shocks. During operation, the directional valve switches the oil circuit, allowing hydraulic fluid to drive the actuator or flow into the accumulator to store energy. When system pressure fluctuates, the accumulator releases oil to maintain stability. Its functions include controlling the direction of movement, protecting system safety, and saving energy and stabilizing pressure. It is widely used in hydraulic systems of machine tools, construction machinery, etc. Currently, the safety directional valve device of a hydraulic integrated accumulator is fixed in its operating position. Vibration during operation can cause the safety directional valve device and its connection points to wobble, leading to unstable connections. Utility Model Content

The protection mechanism includes: two mounting slots 3, both of which are located within the fixed base 1 for mounting components; multiple connecting rods 4, each located within and fixedly connected to the mounting slots 3; multiple protective springs 5, each located within and fixedly connected to the mounting slots 3; multiple connecting pieces 6, each located on and slidably connected to the connecting rods 4; and multiple connecting plates 7, each located on and fixedly connected to the connecting pieces 6.

[0050] refer to Figure 1 and Figure 2 In a preferred embodiment, the protection mechanism further includes: a shock-absorbing part, disposed on the fixed base 1, for shock absorption; and a mounting part, disposed on the connector 6, for mounting and fixing the safety reversing valve device of the hydraulic integrated accumulator.

[0051] With this configuration, the protective spring 5 can prevent the support member 12 used for installation from vibrating synchronously when the device vibrates, ensuring the stability of the support member 12. At the same time, the device generates a lot of noise. The connecting plate 7 is used to connect the connecting member 6 on the same side. The two sides of the connecting member 6 are fixedly connected to the protective spring 5. When the device vibrates, the protective spring 5 on both sides of the connecting member 6 is compressed on one side and stretched on the other side to perform buffering and shock absorption.

[0052] refer to Figure 3 and Figure 4 In a preferred embodiment, the shock-absorbing part includes: multiple sliding grooves 8 disposed within and fixedly connected to the fixed base 1; multiple connecting columns 9 disposed within and fixedly connected to the sliding grooves 8; a support plate 10 disposed on and fixedly connected to the connecting columns 9; and multiple shock-absorbing springs 11 disposed between the fixed base 1 and the support plate 10 for buffering and shock absorption.

[0053] refer to Figure 5 In a preferred embodiment, the mounting part includes: two support members 12, which are disposed on the connector 6 and fixedly connected to the connector 6; and multiple connection holes 13, which are disposed on the support members 12 for mounting and fixing the safety reversing valve device of the hydraulic integrated accumulator.

[0054] With this configuration, the connecting column 9 is used to ensure the stability of the device and prevent it from shaking; the support plate 10 is used to contact the mounting surface; the shock-absorbing spring 11 is used to absorb shock and protect the device; and the connecting hole 13 is threaded so that the device can be fixed with bolts.

[0055] refer to Figure 2 In a preferred embodiment, the installation mechanism includes: a connecting part disposed on the fixed base 1 for fixing the reversing valve body 2; and a supporting part disposed on the fixed base 1 for supporting the reversing valve body 2.

[0056] refer to Figure 3 In a preferred embodiment, the connecting part includes: a fixing cover 14, which is disposed on the fixing seat 1 and is used to fix the reversing valve body 2; and a plurality of fixing bolts 15, which are disposed on the fixing cover 14 and the fixing seat 1 and are used to fix the fixing cover 14.

[0057] refer to Figure 3 and Figure 4 In a preferred embodiment, the support includes: multiple support springs 16, which are disposed within the fixed base 1 and fixedly connected to the fixed base 1; and two support blocks 17, which are disposed on the support springs 16 and fixedly connected to the support springs 16.

[0058] With this configuration, the fixed cover 14 and the fixed base 1 are provided with corresponding threaded holes, which can be connected and fixed using the fixing bolts 15; the support spring 16 and the support block 17 can support the reversing valve body 2 and perform shock absorption at the same time.

[0059] This device, through its installation mechanism, enables stable installation of the directional valve body 2. It also dampens vibrations during valve operation, ensuring stability. Furthermore, its protective mechanism buffers vibrations generated during operation, reducing noise and preventing vibration from affecting connection points, thus ensuring stable connection.

[0060] Working Principle: When the device is in operation, the reversing valve body 2 is placed on top of the fixed base 1, and then the fixed cover 14 is placed on top and fixed to the fixed base 1 with the fixing bolts 15, thus fixing the reversing valve body 2. At the same time, the two sides of the reversing valve body 2 will contact the support block 17, and the support block 17 and the support spring 16 will support the two sides of the reversing valve body 2. Then, the device is fixed in the working position with bolts through the connecting hole 13. When the reversing valve body 2 vibrates during operation, the support spring 16 will first buffer and dampen the vibration. At the same time, the fixed base 1 can also compress the damping spring 11 to dampen the vibration. While the fixed base 1 compresses the damping spring 11, it also compresses and stretches part of the protective spring 5, so that the connecting piece 6 moves on the connecting rod 4. Thus, the protective spring 5 buffers and dampens the vibration while ensuring that the support piece 12 does not move, thereby ensuring the stability of the connection and preventing shaking at the connection position. It also prevents the device from making noise due to vibration at the connection position during operation.

[0061] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
