DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 5 As shown, a trolley track platform comprises a track 1 and a movable platform 2; the movable platform 2 is provided with a support plate 21, a fixed frame 22 is fixedly installed on the top of the support plate 21, a slide groove is provided on the top of the fixed frame 22, and a second connecting rod 24 is movably installed through the slide groove, a movable plate 25 is hinged on the top of the second connecting rod 24, a slide groove is provided on the bottom of the movable plate 25, and a first connecting rod 23 is movably installed through the slide groove, and the bottom of the first connecting rod 23 is hinged to one side of the fixed frame 22;

[0024] During operation, the supporting plate 21 and the fixing frame 22 provide corresponding bearing support for the top components. During operation, the mutual movement of the first connecting rod 23 and the second connecting rod 24 facilitates the height adjustment of the movable plate 25 .

[0025] Furthermore, a plurality of rollers 31 are movably mounted on the top of the track 1, and a plurality of rollers 31 are respectively penetrated and movably mounted with connecting members 29, and a plurality of connecting members 29 are respectively hinged with connecting seats 27;

[0026] During operation, the connecting member 29 is hinged to the connecting member 29, so that the connecting member 29 can move in a circle with the hinge as the axis, so as to drive the roller 31 connected to the other side of the connecting member 29 to move accordingly.

[0027] Furthermore, a support plate 21 is fixedly mounted on the top of the connecting seat 27, and a plurality of air springs 28 are fixedly mounted on the bottom of the supporting plate 21. The bottoms of the plurality of air springs 28 are fixedly mounted on the plurality of connecting seats 27 respectively.

[0028] When working, the air spring 28 is filled with compressed air in a sealed container, and uses the compressibility of gas to achieve its elastic effect. The air spring has ideal nonlinear elastic characteristics. After the height adjustment device is installed, the height of the support plate 21 does not change with the increase or decrease of the load. The spring stiffness can be designed to be lower, with corresponding buffering stability.

[0029] Furthermore, a plurality of buffer springs 32 are fixedly mounted on the bottom of the connection seat 27, a connection block 35 is fixedly mounted on the bottom of the plurality of buffer springs 32, and a roller 31 is movably mounted on one side of the connection block 35;

[0030] During operation, in the process of overall movement, the connection block 35 has a unique elasticity that allows the connection member 29 to move at the connection with the connection seat 27 , which is beneficial to produce relative buffering for the connection seat 27 .

[0031] Furthermore, two hydraulic cylinders 33 are hinged on one side of the second connecting rod 24, and piston rods 34 are movably installed at the output ends of the two hydraulic cylinders 33, and one end of the piston rod 34 is hinged to the first connecting rod 23, and one side of the first connecting rod 23 is hinged to the second connecting rod 24;

[0032] During operation, the hydraulic cylinder 33 converts hydraulic energy into mechanical energy to drive the actuator piston rod 34 at the output end to expand and contract on its inner wall, which is beneficial to correspondingly control the movement between the first connecting rod 23 and the second connecting rod 24 .

[0033] Furthermore, a limit block 26 is fixedly installed on the top of the fixing frame 22, and a movable plate 25 is movably connected to the top of the limit block 26;

[0034] During operation, when the movable plate 25 moves to the lowest height, the installation of the limit block 26 is helpful to limit it and perform corresponding support work at the same time.

[0035] Working principle: By driving the hydraulic cylinder 33, the piston rod 34 at the output end is extended and retracted in its inner wall, so that the piston rod 34 moves between the first connecting rod 23 and the second connecting rod 24. Since the first connecting rod 23 and the second connecting rod 24 are hinged, a force is generated on the first connecting rod 23 to make it cooperate with the second connecting rod 24, and the bottom of the second connecting rod 24 slides on the fixed frame 22 accordingly. The bottom of the first connecting rod 23 moves in a circle with the connection of the fixed frame 22 as the axis. With the movement of the piston rod 34, the height of the movable plate 25 is raised and lowered in the manner of a scissors between the first connecting rod 23 and the second connecting rod 24, and the whole is adjusted accordingly. When the whole moves on the track 1, the connecting seat 27 supports the support plate 21 accordingly, and the roller 31 is used to fit closely with the track 1. During the activity, the installation of the buffer spring 32 is conducive to corresponding buffering to ensure the stability of the whole.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
