DETAILED DESCRIPTION

[0020] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the utility model.

[0021] As Figure 1As shown, the port tractor driven by new energy has a cab at one side of the front end of the frame, and the cab can be turned from back to front when not in use or for maintenance. Due to the bumps during vehicle operation, the cab often collides and fluctuates back and forth during use, affecting the driving experience and comfort of the driver, so a new structure needs to be designed to lock and buffer the bottom of one side of the cab, that is, when the cab is in normal use, a special fixing support device A is needed to lock the position of the cab and achieve effective buffering to improve comfort. Embodiment 1

[0022] Please refer to Figure 2 , Figure 3 and Figure 4 , the fixing support device for the turnable cab of the new energy port tractor, comprising a first mounting plate 10, the inverted L-shaped first mounting plate 10 is stably installed on the frame 1 below the cab by bolts or other suitable fixing methods, the installation back plate 11 is welded on one side of the first mounting plate 10, then two second mounting plates 12 are respectively rotatably connected on the upper two side walls of the installation back plate 11, and the support block 2 is fixedly installed on one side of the two second mounting plates 12 away from the installation back plate 11 and close to each other.

[0023] Then, the fixed plate 8 is welded on the lower part of the first mounting plate 10 and located on both sides of the installation back plate 11, the rotating shaft 6 is installed on one side of the two fixed plates 8 close to each other, then the air bag spring 4 is installed on the upper part of the rotating shaft 6, and the output end of the upper part of the air bag spring 4 is hingedly connected with the bottom of the support block 2, the connecting plate 3 is fixedly installed on one side of the second mounting plate 12 away from the support block 2, and the threaded tube 5 is rotatably connected on one side of the connecting plate 3.

[0024] The threaded tube 5 is provided with two upper and lower threaded tubes, the threaded rod 13 matched with the threaded tube 5 is placed on one side of the two threaded tubes 5 close to each other, the middle nut 16 is fixedly installed on the outer ring of the middle part of the threaded rod 13, and the upper and lower nuts 16 are screwed to the upper and lower parts of the threaded rod 13 respectively, and the outer ring threads of the threaded rod 13 are matched.

[0025] The ball hinge bearing 15 is installed on the lower part of the threaded tube 5, the ball hinge bearing 15 is composed of a ball and a ball shell, the ball is located in the ball shell, the bottom end of the lower threaded tube 5 is fixedly connected with the ball shell, one end of the installation rod 14 is fixedly connected with one side of the ball in the ball shell, the connecting rod 7 is installed on the installation rod 14, the displacement sensor 9 is installed on the other end of the connecting rod 7, and the input end of the air bag spring 4 is connected with the air pump through a hose.

[0026] When the cab is turned back to the normal position, the bottom of the cab can be placed on the support block 2, and the support block 2 can be supported by the air bag spring 4. When the vehicle encounters a bumpy road section during driving, the air bag spring 4 can play a buffering role under the action of the air bag spring 4. If the air volume in the air bag spring 4 is insufficient after a long period of work, the output end of the air bag spring 4 will move downward, thereby causing the support block 2 to move downward, further causing the threaded tube 5 to move downward through the connecting plate 3, and further causing the connecting rod 7 to move through the mounting rod 14. At this time, the displacement sensor 9 can be inducted to start the air pump to inflate the air bag spring 4, so that the air bag spring 4 returns to the original set air volume. Embodiment 2

[0027] Please refer to Figure 2 , Figure 3 and Figure 4 , the application of the fixed support device in another installation scene. First, the first installation plate 10 in the shape of inverted L is fixedly installed on the vehicle frame 1 below the cab. During installation, attention should be paid to the installation position of the first installation plate 10 to ensure the installation accuracy of subsequent components.

[0028] After the back plate 11 is installed and welded, the second installation plate 12 and the support block 2 are installed. At this time, the rotating shaft 6 can be appropriately lubricated during the installation of the fixed plate 8 and the rotating shaft 6 to reduce friction during rotation and improve the service life of the device.

[0029] After the air bag spring 4 is installed, the connection between the output end of the air bag spring 4 and the bottom of the support block 2 should be firm to avoid loosening during use. During the installation of the connecting plate 3 and the threaded tube 5, the rotation of the threaded tube 5 should be smooth.

[0030] During the installation of the threaded rod 13 and the nut 16, a certain pre-tightening force can be appropriately applied when tightening the upper and lower nuts 16 to ensure the reliability of the threaded connection, but it should not be too large to damage the threads.

[0031] During the installation of the spherical bearing 15, the cooperation between the ball and the ball shell should be good, neither too tight to affect rotation nor too loose to cause shaking. The installation sequence of the mounting rod 14, the connecting rod 7, and the displacement sensor 9 is according to the claims. After installation, the displacement sensor 9 is debugged to accurately monitor the displacement.

[0032] In actual use, after the cab is turned over and repaired, the cab is turned back to the normal position, and the bottom of the cab can be placed on the support block 2, and the support block 2 can be supported by the air bag spring 4. When the vehicle encounters a bumpy road section during driving, the air bag spring 4 can play a buffering role under the action of the air bag spring 4.

[0033] In actual use, when the cab is overturned and maintenance is completed, the cab is returned to normal, and the bottom of the cab can be placed on the support block 2, and the support block 2 can be supported by the air bag spring 4. During vehicle driving, when a bumpy road section is encountered, at this time, under the action of the air bag spring 4, the cab can play a buffering role.

[0034] If the air volume in the air bag spring 4 is insufficient after long-term work, at this time, the output end of the air bag spring 4 will move downward, thereby causing the support block 2 to move downward, further causing the threaded pipe 5 to move downward through the connecting plate 3, thereby being able to drive the connecting rod 7 to move through the mounting rod 14. At this time, under the induction of the displacement sensor 9, the air pump can be started to inflate the air bag spring 4, so that the air bag spring 4 returns to the original set air volume.

[0035] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
