DETAILED DESCRIPTION

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figures 1 to 5As shown, the drive device for opening and closing heavy parts of the utility model includes an electrical assembly A and an execution unit B. The electrical assembly A includes a controller 1, a power converter 2, and a hydraulic motor 3. The controller 1, the power converter 2, and the hydraulic motor 3 are installed in the same housing C. The controller 1 is electrically connected to the power converter 2. The hydraulic motor 3 of the electrical assembly A is connected to the power converter 2. The controller 1 is a programmable logic controller. The power converter 2 provides a working voltage to the hydraulic motor 3 when it obtains the instruction of the controller 1. The hydraulic motor 3 works when it obtains the working voltage. The power converter 2 is a prior art and will not be described in detail here.

[0024] The execution unit B includes a housing 4, a sliding component 5, a hydraulic actuator 6, a connecting block 7, and a connecting rod assembly 8. The housing 4 is rectangular. The housing 4 and the sliding component 5 are located in the housing 4 and slideably cooperate with the housing 4. One end of the hydraulic actuator 6 is connected to the housing 4. One end of the hydraulic actuator 6 is connected to the housing 4 by a pin 10. The hydraulic motor 3 is connected to the hydraulic actuator 6. The hydraulic motor 3 is connected to the hydraulic actuator 6 by an oil pipe. The hydraulic actuator 6 is a hydraulic cylinder. The medium in the hydraulic cylinder is preferably hydraulic oil, which is provided by the hydraulic motor 3. The connecting block 7 is connected to the sliding component 5 and the other end of the hydraulic actuator 6. The connecting rod assembly 8 is connected to the connecting block 7.

[0025] The utility model uses hydraulic drive to provide greater thrust, and uses hydraulic oil circuits to separate the electrical assembly A and the actuator B. Since the hydraulic motor 3 is located in the housing C but not in the actuator B, the arrangement of the actuator B is more flexible and compact. The housing 4, the sliding component 5 and the sliding matching structure of the two are cleverly designed to ensure the stability of the piston rod end of the hydraulic actuator 6 during movement and improve the life of the hydraulic actuator 6. In order to highlight the product advantages and optimize the size of the housing 4 as much as possible, the entire actuator B is designed with the optimal size of the actuator B and the simplest and most efficient connection form in mind. When in the retracted state, the sliding component 5 is hidden inside the housing 4, and when in the extended state, the piston rod and the sliding component 5 are exposed outside the housing 4.

[0026] The sliding component 5 includes a slider 5a, a first receiving groove 5b is provided on the slider 5a, a part of the hydraulic actuator 6 is located in the first receiving groove 5b, a first sliding portion 5c is provided on the outer wall of the slider 5a, a second sliding portion 4a is provided on the inner wall surface of the housing 4, and the first sliding portion 5c and the second sliding portion 4a are slidably matched.

[0027] When the piston rod of the hydraulic actuator 6 is extended or retracted, the rod end will be subjected to lateral force, which will affect the seal at the piston rod and reduce the life of the entire device. In the utility model, a sliding component 5 is designed, and a connecting block 7 is connected to the sliding component 5 and the other end (rod end) of the hydraulic actuator 6. The first sliding part 5c on the sliding component 5 is slidably matched with the second sliding part 4a provided on the inner wall surface of the housing 4, providing the sliding component 5 with upper and left and right rail support, ensuring that the radial stability is maintained during the extension or retraction of the rod end of the hydraulic actuator 6, and the sliding component 5 is stable in two directions during operation without twisting.

[0028] The connecting block 7 is located in the first receiving groove 5b. It also includes a connecting component 9. The sliding component 5 is provided with a first assembly hole 5d. The connecting block 7 includes a connecting block body 7a. The connecting block body 7a is provided with a second receiving groove 7b. The side wall of the connecting block body 7a is provided with a second assembly hole 7c. The other end of the hydraulic actuator 6 is located in the second receiving groove 7b. The connecting component 9 passes through the first assembly hole 5d, the second assembly hole 7c and the other end of the hydraulic actuator 6, so that the connecting block 7 is connected to the sliding component 5 and the other end of the hydraulic actuator 6.

[0029] The connecting rod assembly 8 includes a first connecting head 8a, a connecting rod body 8b, a second connecting head 8c and an L-shaped connecting plate 8d.
