Description

Technical Field

[0001] This utility model belongs to the field of lifting mechanism technology, specifically relating to a lifting electro-hydraulic actuator. Background Technology

[0002] Existing lifting actuators typically employ a closed or compact structural design, encapsulating core components (such as actuators) within a sealed or semi-sealed space. While this design offers some protection for internal components, confining the core components to a small space reduces overall structural rigidity and impacts movement accuracy. Furthermore, when maintenance or replacement of hydraulic rods or adjustment of actuator parameters is required, the limited operating space often necessitates the disassembly of numerous peripheral components to access the core parts, resulting in complex, time-consuming maintenance processes and potential safety hazards.

[0003] Therefore, based on some of the situations in the prior art described above, this application has made further designs and improvements. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution.

[0005] A lifting electro-hydraulic actuator is used to realize the relative movement of a first base and a second base. It includes a first mounting body, an electro-hydraulic actuator, a guide column, and a second mounting body. The first mounting body is mounted on the first base, and the second mounting body is mounted on the second base. The electro-hydraulic actuator is provided with a telescopic hydraulic rod, and the electro-hydraulic actuator is assembled on the second mounting body. The hydraulic rod is assembled and connected to the first mounting body. The guide column is assembled on the first mounting body, and the second mounting body is movably assembled with the guide column. Both the first and second mounting bodies are hollow frame structures, and the electro-hydraulic actuator is located in the middle of the frame structure and exposed.

[0006] Furthermore, the first mounting body includes a first crossbeam plate located on the upper and lower sides and a first side plate located on the left and right sides, and the two ends of the guide post are fixedly connected to the first crossbeam plate on the upper and lower sides respectively; the second mounting body includes a second crossbeam plate located on the upper and lower sides and a second side plate located on the left and right sides, the second crossbeam plate is provided with a guide hole for the guide post to pass through, and the upper second crossbeam plate is also provided with a through hole for the hydraulic rod to pass through.

[0007] Furthermore, a first mounting hole is provided on the front side of the first crossbeam plate, and a first mating hole is provided on the first side plate to mate with the first mounting hole. The first mounting hole and the first mating hole are fixedly connected by fasteners.

[0008] Furthermore, the first side plate has a T-shaped structure, including a first mounting part, a first base part and a first limiting part, a first mating hole located on the first mounting part, and a first mounting groove for fixed connection with the first base body is also provided on the first mounting part.

[0009] Furthermore, the second crossbeam plate has second mounting holes on its left and right sides, and the second side plate has second mating holes that mate with the second mounting holes. The second mounting holes and the second mating holes are fixedly connected by fasteners.

[0010] Furthermore, the second side plate has an L-shaped structure, including a second mounting part and a second base part, a second mating hole located on the second mounting part, and a second mounting groove provided on the second base part for fixed connection with the second base body.

[0011] Furthermore, an arc-shaped space is provided on the first side plate, and the surface of the second side plate with the second mating hole is exposed from the arc-shaped space.

[0012] Furthermore, a guide mounting hole is provided on the end face of the guide column, and a guide mating hole is provided on the first crossbeam plate to match the guide mounting hole. The guide mounting hole and the guide mating hole are fixedly connected by fasteners.

[0013] Compared with the prior art, this application has the following beneficial technical effects:

[0014] 1. The first and second mounting bodies adopt a hollow frame structure, placing core components such as electro-hydraulic actuators and guide columns in an open space. This layout design has good overall rigidity, high movement accuracy, and facilitates daily inspection and troubleshooting. When it is necessary to replace the hydraulic rod or adjust the actuator parameters, there is sufficient operating space, effectively avoiding the maintenance difficulties caused by the limited space in traditional enclosed structures.

[0015] 2. The connection between components adopts standardized fasteners and mating hole design, which reduces the reliance on special tools and simplifies the installation process.

[0016] 3. The arc-shaped space design on the first side plate exposes the key operating surface of the second side plate. The first and second bases can be separated by directly removing the fasteners on the second side plate without completely disassembling the mounting body, which further improves the convenience of maintenance.

[0034] Reference Figures 1 to 9 A lifting electro-hydraulic actuator is disclosed for achieving relative movement between a first base and a second base. It includes a first mounting body 100, an electro-hydraulic actuator 200, a guide column 300, and a second mounting body 400. The first mounting body 100 is mounted on the first base, and the second mounting body 400 is mounted on the second base. The electro-hydraulic actuator 200 is equipped with a telescopic hydraulic rod 210 and is mounted on the second mounting body 400, with the hydraulic rod 210 connected to the first mounting body 100. The guide column 300 is mounted on the first mounting body 100, and the second mounting body 400 is movably mounted to the guide column 300. Both the first mounting body 100 and the second mounting body 400 are hollow frame structures, with the electro-hydraulic actuator 200 located in the middle of the frame structure and exposed. By exposing the electro-hydraulic actuator 200 in the middle of the frame structure and cooperating with the guiding function of the guide column 300, precise relative movement between the first and second bases is achieved. This structure ensures the driving efficiency of the electro-hydraulic actuator 200 while enhancing overall rigidity through the support of the frame-type mounting body, preventing offset or tilting during movement and ensuring the stability and reliability of the lifting motion. Furthermore, this layout design facilitates daily inspection and troubleshooting. When it is necessary to replace the hydraulic rod 210 or adjust actuator parameters, there is ample operating space, effectively avoiding the maintenance difficulties caused by space constraints in traditional enclosed structures.

[0035] Specifically, the first mounting body 100 includes first crossbeam plates 110 located on the upper and lower sides and first side plates 120 located on the left and right sides. The two ends of the guide post 300 are fixedly connected to the first crossbeam plates 110 on the upper and lower sides, respectively. The second mounting body 400 includes second crossbeam plates 410 located on the upper and lower sides and second side plates 420 located on the left and right sides. The second crossbeam plate 410 is provided with a guide hole 411 for the guide post 300 to pass through, and the upper second crossbeam plate 410 is also provided with a through hole 412 for the hydraulic rod 210 to pass through. The electro-hydraulic actuator 200 is installed between the second crossbeam plates 410, and the hydraulic rod 210 is fixedly connected to the upper first crossbeam plate 110.

[0036] For ease of maintenance, this application employs standard fasteners for connection and assembly and adopts a maintenance-friendly structural layout. Specifically, the front side of the first crossbeam plate 110 is provided with a first mounting hole 111, and the first side plate 120 is provided with a first mating hole 121 that mates with the first mounting hole 111. The first mounting hole 111 and the first mating hole 121 are fixedly connected by fasteners. The left and right sides of the second crossbeam plate 410 are provided with second mounting holes 413, and the second side plate 420 is provided with second mating holes 421 that mate with the second mounting holes 413. The second mounting holes 413 and the second mating holes 421 are fixedly connected by fasteners. The first side plate 120 is provided with an arc-shaped space 122, and the surface of the second side plate 420 with the second mating holes 421 is exposed through the arc-shaped space 122, directly exposing the mating holes of the second side plate 420, further optimizing the operability of maintenance. The guide column 300 has a guide mounting hole 301 on its end face, and the first crossbeam plate 110 has a guide mating hole 112 that matches the guide mounting hole 301. The guide mounting hole 301 and the guide mating hole 112 are fixedly connected by fasteners. This design facilitates quick disassembly and replacement of components (such as side plates or crossbeam plates), significantly reducing maintenance costs and downtime.

[0037] To ensure structural reliability, the first side plate 120 has a T-shaped structure, including a first mounting portion 123, a first base 124, and a first limiting portion 125. A first mating hole 121 is located on the first mounting portion 123, and the first mounting portion 123 is also provided with a first mounting groove 126 for fixed connection with the first base. The second side plate 420 has an L-shaped structure, including a second mounting portion 422 and a second base 423. A second mating hole 421 is located on the second mounting portion 422, and the second base 423 is provided with a second mounting groove 424 for fixed connection with the second base. The T-shaped and L-shaped structures can significantly enhance the bending strength and impact resistance of the side plates, ensuring the stability of the actuator during long-term operation.
