DETAILED DESCRIPTION
[0021] The preferred embodiments of the pry-mounted LNG two-pump double-machine gas filling device will be described below with reference to the accompanying drawings, and it should be understood that the preferred embodiments described herein are only used to illustrate and explain the pry-mounted LNG two-pump double-machine gas filling device, and are not used to limit the pry-mounted LNG two-pump double-machine gas filling device.
[0022] With reference to Figure 1 , Figure 2 and Figure 3 , the pry-mounted LNG two-pump double-machine gas filling device comprises a pry-mounted box 1, a two-pump double-machine gas filling equipment body 2 arranged in the pry-mounted box 1, and a protective plate 3 arranged on the two sides of the outer side wall of the pry-mounted box 1, the two sides of the outer side wall of the pry-mounted box 1 are provided with mounting grooves 4, the inner top wall of each mounting groove 4 is fixedly connected with a motor 5, the output end of the motor 5 is fixedly connected with a first threaded rod 6, the end of the first threaded rod 6 away from the motor 5 is fixedly connected with a second threaded rod 7, the surface thread direction of the first threaded rod 6 is opposite to that of the second threaded rod 7, and the outer side wall of each of the first threaded rod 6 and the second threaded rod 7 is threadedly connected with a threaded sleeve 8, in use, the motor 5 can drive the first threaded rod 6 and the second threaded rod 7 to rotate in the same direction, because the surface thread direction of the first threaded rod 6 is opposite to that of the second threaded rod 7, when the first threaded rod 6 and the second threaded rod 7 rotate in the same direction, if the threaded sleeve 8 threadedly connected with the first threaded rod 6 rises, the threaded sleeve 8 threadedly connected with the second threaded rod 7 will descend, and if the threaded sleeve threadedly connected with the first threaded rod 6 descends, the threaded sleeve 8 threadedly connected with the second threaded rod 7 will rise;
[0023] With reference to Figure 1 , Figure 2 and Figure 3 , one side of the outer side wall of the threaded sleeve 8 is rotatably connected with a connecting assembly, the end of the connecting assembly away from the threaded sleeve 8 is rotatably connected with the protective plate 3, after the pry-mounted box 1 is hoisted, the motor 5 can drive the first threaded rod 6 and the second threaded rod 7 to rotate, and drive the threaded sleeve threadedly connected with the first threaded rod 6 to descend and the threaded sleeve 8 threadedly connected with the second threaded rod 7 to rise, and then the connecting assembly pushes the protective plate 3 away from the pry-mounted box 1, so as to protect the pry-mounted box 1 and the two-pump double-machine gas filling equipment body 2 inside the pry-mounted box 1;
[0024] With reference to Figure 1 , Figure 2 and Figure 3 , the protective plate 3 is uniformly provided with a reflective strip 16, and when the vehicle light shines on the reflective strip 16 in the night environment, the reflective strip 16 reflects light, thereby playing a certain warning role for the driver of the vehicle. The protective plate 3 is uniformly provided with a guide roller 17 whose axis direction is perpendicular to the ground. When the vehicle device is protected by the protective plate 3, the vehicle will contact the guide roller 17 and drive the guide roller 17 to rotate, thereby causing a certain deviation of the impact angle of the vehicle. Limiting holes 9 are formed in the two sides of the top and bottom of the pry box 1. The four corners of the side of the protective plate 3 close to the pry box 1 are fixedly connected with limiting rods 10 matched with the limiting holes 9. When the protective plate 3 moves towards or away from the pry box 1, the limiting rods 10 slide in the limiting holes 9, thereby improving the stability of the protective plate 3 during movement.
[0025] With reference to Figure 2 , Figure 3 and Figure 4 , the connecting assembly includes a first connecting rod 11 rotatably connected to the threaded sleeve 8 and a second connecting rod 12 rotatably connected to the protective plate 3. The end of the first connecting rod 11 away from the threaded sleeve 8 is fixedly connected with a damping shock absorber 13. The end of the damping shock absorber 13 away from the first connecting rod 11 is fixedly connected to the second connecting rod 12. When the vehicle impacts the protective plate 3, the damping shock absorber 13 is extruded by the first connecting rod 11 and the second connecting rod 12 to deform, thereby absorbing the impact energy of the vehicle and reducing the impact of the vehicle on the two-pump dual-machine gas filling equipment body 2 in the pry box 1. The pry box 1 is provided with a vibration sensor 14, and the top of the pry box 1 is provided with a warning light strip 15 electrically connected with the vibration sensor 14. When the device as a whole is impacted, the vibration sensor 14 is impacted and drives the warning light strip 15 to light up, thereby warning the workers.
[0026] The implementation principle of the present application is that when the device needs to be transported, the motor 5 drives the first threaded rod 6 and the second threaded rod 7 to rotate, and drives the threaded sleeve 8 threadedly connected to the first threaded rod 6 to rise and the threaded sleeve 8 threadedly connected to the second threaded rod 7 to descend, thereby driving the protective plate 3 to move towards the side close to the pry box 1, reducing the overall width of the device, and thereby reducing the transportation difficulty of the device.
[0027] When the device transportation and hoisting are completed, the motor 5 drives the first threaded rod 6 and the second threaded rod 7 to rotate, and drives the threaded sleeve 8 threadedly connected to the first threaded rod 6 to descend and the threaded sleeve 8 threadedly connected to the second threaded rod 7 to rise, thereby moving the protective plate 3 to the side away from the pry box 1, and protecting the pry box 1 and the two-pump dual-machine gas filling equipment body 2 arranged in the pry box 1.
[0028] At night, the reflective strip 16 can reflect the light of the vehicle, thereby playing a certain warning effect on the driver, when a vehicle hits the guard plate 3, the vehicle will contact the guide roller 17 and drive the guide roller 17 to rotate, thereby making the vehicle impact angle deviate to a certain extent, as far as possible to reduce the possibility of the vehicle directly impacting the pry container 1, at the same time, when the impact occurs, the damping shock absorber 13 can absorb the kinetic energy of the impact to a certain extent, reducing the impact damage;
[0029] When the vehicle hits, the guard plate 3 can play a certain protective effect on the pry container 1, and can absorb the impact kinetic energy to a certain extent through the damping shock absorber 13, but the pry container 1 will still vibrate to a certain extent, and then the vibration sensor 14 drives the warning light strip 15 to light up, warning the staff.
[0030] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application are described in detail, for those skilled in the art, it can still be modified according to the technical solutions recorded in the foregoing embodiments, or equivalent replacement of some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
