[0002] The hydraulic and pneumatic integrated training platform is a teaching device used to train and educate students in the field of hydraulic and pneumatic transmission systems. The platform integrates hydraulic, pneumatic and electrical control technologies, simulates real industrial control systems, and allows students to be familiar with and operate various components, such as pumps, valves, cylinders, etc., and program and control through PLC. In current technology, the hydraulic and pneumatic integrated training platform is assembled, resulting in a fixed height of the assembled platform. During the operation of the students, due to the height difference of each person, it is inconvenient to operate the hydraulic and pneumatic integrated training platform. For this reason, we proposed a hydraulic and pneumatic integrated training platform. Utility Model Content

[0025] See also Figure 1-4 A hydraulic and pneumatic integrated training platform comprises a support platform 1, a training platform 2 is slidably connected to the support platform 1, a hydraulic and pneumatic device 3 is fixedly connected to the bottom of the training platform 2, an inverted L-shaped side plate 4 is fixedly connected to both ends of the training platform 2, two groups of mutually symmetrical vertical support columns 6 are fixedly arranged on the bottom inner wall of the support platform 1, a stabilizing sleeve 7 is slidably sleeved on the support column 6, a cylinder 11 is fixedly installed on the bottom inner wall of the support platform 1, and further comprises:

[0026] The sliding assembly is installed between the two sets of support columns 6 and is used to adjust the up and down position of the training platform 2.

[0027] The positioning assembly is installed on the bottom inner wall of the support platform 1 and is used to displace the sliding assembly.

[0028] The two groups of side panels 4 are fixedly connected to the side away from the training platform 2. The two groups of limit plates 5 are slidably connected to the inner walls of the two sides of the support platform 1 respectively. The limit plates 5 fixedly connected to the side panels 4 at both ends of the training platform 2 are connected to the inner wall of the support platform 1 during the downward sliding of the training platform 2, so as to prevent the position deviation of the training platform 2 during the downward sliding. If you want to lift the position of the training platform 2 upward, you can make the piston rod on the cylinder 11 retract and perform the above operation in reverse.

[0029] A horizontal cross bar 8 is fixedly connected between the two groups of stabilizing sleeves 7, and a vertical upright pole 10 is fixedly connected to the top of the cross bar 8 corresponding to the middle position, and the top of the upright pole 10 is fixedly connected to the bottom of the training platform 2. The cross bar 8 drives the two groups of stabilizing sleeves 7 to slide downward on the two groups of supporting columns 6, and the upright pole 10 at the top of the cross bar 8 drives the training platform 2 to move downward in the support platform 1.

[0030] The tops of the two groups of support columns 6 are slidably connected to the training platform 2 and the tops of the two groups of support columns 6 extend out of the top of the training platform 2. The ends of the support columns 6 extending out of the training platform 2 are fixedly connected to the limiting covers 9.

[0031] The sliding assembly includes a hinge seat 15, a fixed shaft 16 and a roller 17. The bottom of the cross bar 8 is fixedly provided with a hinge seat 15 corresponding to the bottom of the vertical rod 10. The bottom of the hinge seat 15 is provided with an open groove. The fixed shaft 16 is fixedly connected between the inner walls on both sides of the open groove. The roller 17 is rotatably sleeved on the fixed shaft 16. The bottom plate 13 drives the tripod 12 to move synchronously during the sliding process. Due to the forward displacement of the tripod 12, the roller 17 is displaced in the downhill direction in the inclined groove 14 by gravity.

[0032] The positioning assembly includes a tripod 12, a base plate 13 and an inclined groove 14. The bottom inner wall of the support platform 1 is slidably connected with the base plate 13, the end of the base plate 13 is fixedly connected to the piston rod on the cylinder 11, the top of the base plate 13 is fixedly connected to the tripod 12, and an inclined groove 14 is provided on the slope end of the tripod 12. When it is necessary to adjust the up and down position of the training platform 2, start the cylinder 11, so that the piston rod on the cylinder 11 is pushed forward and drives the base plate 13 to slide on the bottom inner wall of the support platform 1.

[0033] The roller 17 is slidably engaged in the inclined groove 14 , and the roller 17 rotates synchronously on the fixed shaft 16 during the displacement process. The cross bar 8 on the hinge seat 15 gradually moves downward when the roller 17 moves in the inclined groove 14 in the downhill direction.

[0034] Working principle: When the up and down position of the training platform 2 needs to be adjusted, the cylinder 11 is started, so that the piston rod on the cylinder 11 pushes forward and drives the bottom plate 13 to slide on the bottom inner wall of the support platform 1. The bottom plate 13 drives the tripod 12 to move synchronously during the sliding process. Due to the forward displacement of the tripod 12, the roller 17 moves downward in the inclined groove 14 by gravity. The roller 17 rotates synchronously on the fixed axis 16 during the displacement process. The cross bar 8 on the hinge seat 15 moves in the inclined groove 14 through the roller 17. When moving in the downhill direction, it gradually moves downward. At the same time, the cross bar 8 drives the two groups of stabilizing sleeves 7 to slide downward on the two groups of supporting columns 6, and the vertical rod 10 on the top of the cross bar 8 drives the training platform 2 to move downward in the supporting platform 1. The limit plates 5 fixedly connected to the side plates 4 at both ends of the training platform 2 are clamped on the inner wall of the supporting platform 1 during the downward sliding of the training platform 2 to prevent the training platform 2 from position deviation during the downward sliding process. If you want to lift the position of the training platform 2 upward, make the piston rod on the cylinder 11 retract and reverse the above operation.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
