Description

Technical Field

[0001] This application relates to the field of electro-hydraulic actuators, and more specifically, to a detachable electro-hydraulic actuator. Background Technology

[0002] An electro-hydraulic actuator is a hydraulically driven manipulator integrating mechanics, electricity, and hydraulics. It is suitable for applications requiring reciprocating push-pull linear motion, as well as for applications requiring lifting, lowering, or clamping of workpieces. It can also achieve centralized or automatic control in remote, hazardous areas. For example, a separate electro-hydraulic actuator with Chinese patent application number CN202323221462.X includes a power unit and a hydraulic cylinder, connected by an oil pipe. The power unit includes a motor and an oil tank, with the motor's output end mounted at the end of the oil tank. A hydraulic pump is connected to the side wall of the oil tank, and one end of the hydraulic pump is connected to a hydraulic manifold. This invention separates the power unit and the hydraulic cylinder. When the hydraulic cylinder is damaged, only the cylinder needs to be replaced. Components that are difficult to disassemble and repair, such as the motor, hydraulic pump, and hydraulic valve block, do not need to be handled. Disassembly, repair, and replacement are more convenient than before, fully meeting the requirements of on-site work.

[0003] However, the above solution still has certain drawbacks: First, when the push rod extends, dust easily adheres to its surface and is brought into the cylinder, which can cause damage after long-term use and is inconvenient to prevent dust. Second, the length of the oil pipe is fixed, which is inconvenient to extend or retract, resulting in low applicability and reduced practicality. Utility Model Content

[0004] To overcome the above shortcomings, this application provides a detachable electro-hydraulic actuator, which aims to improve the problems in related technologies where dust easily adheres to the surface of the actuator when it extends, causing it to be brought into the cylinder body, which can easily cause damage after long-term use and is inconvenient for dust prevention. In addition, the length of the oil pipe is fixed, which is inconvenient for extension and retraction, resulting in low applicability and reduced practicality.

[0005] This application provides a detachable electro-hydraulic actuator including a connecting assembly and a protective assembly.

[0006] The connecting assembly includes an oil tank, a motor, a first telescopic hose, an oil pipe, and a second telescopic hose. The motor is located on one side of the oil tank. Both first telescopic hoses are connected to the oil tank. The oil pipe is fixedly connected to the first telescopic hose, and the second telescopic hose is fixedly connected to the oil pipe. The protective assembly includes a cylinder body, a push rod, a fixing ring, a dustproof telescopic cover, and elastic clips. The second telescopic hose is connected to the cylinder body. The push rod is slidably connected to the cylinder body. The fixing rings are fixedly connected to both the cylinder body and the push rod. The two elastic clips are located on both sides of the dustproof telescopic cover, and the dustproof telescopic cover is slidably engaged with the fixing rings through the elastic clips.

[0007] In one specific implementation, a hydraulic pump is connected to the side wall of the oil tank, and one end of the hydraulic pump is connected to a hydraulic integrated block.

[0008] In the above implementation process, a series of parameters such as pressure and flow rate of the device can be controlled by hydraulic pumps and hydraulic manifolds.

[0009] In one specific implementation, a first connector is provided at one end of the second telescopic hose.

[0010] In the above implementation process, a first connector is provided at one end of the second telescopic hose, which can serve as a connection.

[0011] In one specific implementation, two second connectors are provided on one side of the cylinder body, the first connector is in contact with the second connector, a first clamp is provided on one side of the second connector, a second clamp is hinged to one side of the first clamp, and two bolts are provided on one side of the second clamp, the bolts being threadedly connected to the first clamp.

[0012] In the above process, the first clamp, the second clamp and the bolt can be used to seal the connection between the first connector and the second connector, and at the same time, it can facilitate disassembly.

[0013] In one specific implementation, the fixing ring has holes and grooves on both sides.

[0014] In the above implementation process, holes and grooves are provided on both sides of the fixing ring, which can serve as a connection.

[0015] In one specific implementation, the elastic clip includes a bracket, a rod, and a spring. The rod is connected through the bracket and one side of the dustproof telescopic cover. The rod is slidably connected to the slot. One end of the spring is fixedly connected to the bracket, and the other end of the spring is fixedly connected to the rod.

[0016] In the above process, when it is necessary to disassemble the dustproof telescopic cover, the insert rod is pulled to separate the insert rod from the slot, and then the dustproof telescopic cover can be separated from the fixing ring. The reverse operation can be used to install the dustproof telescopic cover.

[0017] In one specific implementation, a pull plate is provided at one end of the insertion rod.

[0018] In the above implementation process, a pull plate is provided at one end of the insertion rod to facilitate pulling the insertion rod.

[0019] Compared with the prior art, the beneficial effects of this application are as follows: First, the oil tank and motor are separated from the cylinder and push rod. When the cylinder and push rod are damaged, only the cylinder and push rod need to be replaced. Components that are inconvenient to disassemble and repair, such as the oil tank and motor, do not need to be dealt with. Disassembly, repair, and replacement are more convenient than before, which can fully meet the on-site work requirements. At the same time, the dustproof telescopic cover can protect the outside of the push rod from dust, thus preventing dust from adhering to the outer wall after the push rod is extended and being brought into the cylinder when it is retracted, achieving a dustproof effect. In addition, the first telescopic hose and the second telescopic hose can be extended according to the usage situation, improving applicability and thus improving practicality.

Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] Please see Figure 1-4 This application provides a detachable electro-hydraulic actuator including a connecting assembly 100 and a protective assembly 200.

[0028] Please see Figure 1-2 The connecting assembly 100 includes an oil tank 110, a motor 120, a first telescopic hose 130, an oil pipe 140, and a second telescopic hose 150. The motor 120 is located on one side of the oil tank 110. Both first telescopic hoses 130 are connected to the oil tank 110. The oil pipe 140 is fixedly connected to the first telescopic hose 130. The second telescopic hose 150 is fixedly connected to the oil pipe 140. A hydraulic pump 111 is connected to the side wall of the oil tank 110. One end of the hydraulic pump 111 is connected to a hydraulic integrated block 112. The hydraulic pump 111 and the hydraulic integrated block 112 can control a series of parameters such as pressure and flow rate of the device. One end of the second telescopic hose 150 is provided with a first connector 151, which serves as a connection.

[0029] Please see Figure 1 , Figure 3 and Figure 4 The protective assembly 200 includes a cylinder body 210, a push rod 220, a fixing ring 230, a dustproof telescopic cover 240, and elastic clips 250. A second telescopic hose 150 is connected to the cylinder body 210. The push rod 220 is slidably connected to the cylinder body 210. The fixing ring 230 is fixedly connected to both the cylinder body 210 and the push rod 220. Two elastic clips 250 are located on both sides of the dustproof telescopic cover 240, and the dustproof telescopic cover 240 is slidably engaged with the fixing ring 230 via the elastic clips 250. Two second connecting hoses are located on one side of the cylinder body 210. The first connector 151 and the second connector 211 are in contact. The second connector 211 has a first clamp 212 on one side and a second clamp 213 hinged to one side of the first clamp 212. The second clamp 213 has two bolts 214 on one side and the bolts 214 are threaded to the first clamp 212. The first connector 151 and the second connector 211 can be sealed and connected by the cooperation of the first clamp 212, the second clamp 213 and the bolts 214, which can also facilitate disassembly.

[0030] In some specific implementations, the fixing ring 230 has slots 231 on both sides, which serve as a connection. The elastic clip 250 includes a bracket 251, a rod 252, and a spring 253. The rod 252 is connected through the bracket 251 and one side of the dustproof telescopic cover 240. The rod 252 is slidably connected to the slot 231. One end of the spring 253 is fixedly connected to the bracket 251, and the other end is fixedly connected to the rod 252. When the dustproof telescopic cover 240 needs to be disassembled, the rod 252 is pulled to separate it from the slot 231, and then the dustproof telescopic cover 240 can be separated from the fixing ring 231. Conversely, the dustproof telescopic cover 240 can be installed. One end of the rod 252 is provided with a pull plate 2521, which facilitates pulling the rod 252.

[0031] The working principle of this detachable electro-hydraulic actuator is as follows: During use, the oil tank 110 and motor 120 are first separated from the cylinder 210 and actuator 220. When the cylinder 210 and actuator 220 are damaged, only the cylinder 210 and actuator 220 need to be replaced. Components that are difficult to disassemble and repair, such as the oil tank 110, motor 120, hydraulic pump 111, and hydraulic manifold 112, do not need to be handled. Disassembly, repair, and replacement are more convenient than before, fully meeting the on-site work requirements. Simultaneously, the dustproof telescopic cover 240 can protect the actuator 220 from dust. This design avoids dust adhering to the outer wall of the push rod 220 after it extends, which would then be carried into the cylinder 210 when it retracts, thus achieving a dustproof effect. When it is necessary to disassemble the dustproof telescopic cover 240, the insert rod 252 is pulled to separate it from the slot 231, and then the dustproof telescopic cover 240 can be separated from the fixing ring 230. Conversely, the dustproof telescopic cover 240 can be installed by pulling the insert rod 252. At the same time, the first telescopic hose 130 and the second telescopic hose 150 can be extended according to the usage situation, improving applicability and thus improving practicality.

[0032] It should be noted that the specific models and specifications of the hydraulic pump 111, hydraulic integrated block 112, and motor 120 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0033] The power supply and operating principle of the hydraulic pump 111, hydraulic integrated block 112 and motor 120 are clear to those skilled in the art and will not be described in detail here.
