[0019] The technical solutions in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application; based on the embodiments, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope.
[0020] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the embodiments and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the embodiments.
[0021] Since the damping force and the damping direction of the current shock absorber have certain limitations, and the vibration frequency and direction of the methanol generator under different powers and uneven road surfaces have certain differences, when the shock absorber is applied between the mobile methanol generator base and the mobile chassis, it cannot play a good damping and noise reduction effect, therefore, the embodiment of the present application provides a mobile methanol generator damping device, which aims to improve the damping range and damping direction of the shock absorber, and provide better damping effect for the methanol generator under different conditions, the device mainly comprises a damping unit 100 and a second shock absorber 20 arranged between the methanol generator set 01 and the trailer 02.
[0022] As shown in Figure 1 , Figure 2 and Figure 3 , a plurality of damping units 100 are arranged on the trailer 02, generally, the damping units 100 are distributed at least at the four corners of the trailer 02, and can be increased according to the weight of the methanol generator set 01, one damping unit 100 comprises two or more first shock absorbers 10 arranged in a central symmetrical manner, in order to make the damping range covered by the first shock absorber wider, the damping force of each first shock absorber 10 can be set differently, in this way, a plurality of first shock absorbers 10 jointly constitute a wider range of damping frequency, so as to adapt to the medium-high frequency vibration of the methanol generator under different working conditions, and better damping effect can be brought.
[0023] Further, the second shock absorber 20 comprises a connecting rod connected with the methanol generator set 01, the connecting rod is perpendicular to the methanol generator set 01, in this way, the second shock absorber 20 plays a part of the bearing work, and in cooperation with the first shock absorber 10, the second shock absorber 20 bears the damping and vibration filtering effect in the vertical direction.
[0024] The damping force of the first damper 10 is different from that of the second damper 20, so that a wide range of damping frequencies can be obtained after the combination of the first damper 10 and the second damper 20. The first damper 10 includes a hinged rod 12 connected to the methanol generator set 01, and an angle between the hinged rod 12 and the bottom surface of the methanol generator set 01 is set to an acute angle.
[0025] In some embodiments, the same damping unit 100 can include 2-6 first dampers 10, which are symmetrically distributed around a fixed bearing center. The shaft is perpendicular to the load surface of the trailer 02, and the angle between the hinged rod 12 and the bottom surface of the methanol generator set 01 is set to 45°. When the methanol generator set 01 is working, the hinged rod 12 can swing within a certain angle range and attenuate or eliminate the vibration in the first damper 10. It can be understood that the angle between the hinged rod 12 and the bottom surface of the methanol generator set 01 can also be set to between 30° and 60° or other angles. When the angle of the hinged rod 12 is 45°, the force in the horizontal direction and the vertical direction is balanced. When the vertical vibration is obvious, the horizontal vibration can be set to a larger angle, for example, 70°-80°. The angle has multiple choices, and mixed use has more direction filtering effect.
[0026] As shown in Figure 3 , one damping unit 100 in the figure includes four first dampers 10 that are centrally symmetrically distributed, and the angle of the hinged rod 12 on each first damper 10 is 45°, which can provide stable support and multi-directional vibration filtering effect.
[0027] As shown in Figure 4 , Figure 5 and Figure 6 , the first damper 10 further includes a shell 11 and a damping plug 13 mounted on the shell 11. The first end of the hinged rod 12 is hinged to the supporting shaft 012 of the bottom of the methanol generator set 01, the second end of the hinged rod 12 extends into the interior of the shell 11, the damping plug 13 is clamped between the hinged rod 12 and the shell 11, and when the first end of the hinged rod 12 moves around the supporting shaft 012, the second end of the hinged rod 12 is damped by the damping plug 13.
[0028] The upper surface of the trailer 02 is provided with a plurality of mounting areas 020, and the area of the bottom of the methanol generator set 01 corresponding to the mounting area 020 is provided with a plurality of supporting shafts 012. The first damper 10 mounted on the mounting area 020 can install the first end of the hinged rod 12 to the supporting shaft 012, so that the hinged rod 12 can be hinged and rotated with the supporting shaft 012. The second end of the hinged rod 12 cooperates with the damping plug 13 in the shell 11 to achieve the damping effect.
[0029] Further, asFigure 5 and Figure 6 As shown in the figure, the articulated rod 12 comprises a connecting rod 121 and a ball head 122 and a shaft cylinder 123 fixed at both ends of the connecting rod 121 respectively, the inside of the shell 11 is provided with a movable cavity 1101 accommodating the ball head 122, and the shell 11 is provided with a movable slot 1102, the ball head 122 is installed in the movable cavity 1101, and the connecting rod 121 penetrates through the movable slot 1102, and the shaft cylinder 123 is hingedly installed on the supporting shaft 012.
[0030] In some embodiments, the ball head 122 is configured as a spherical shape, the movable cavity 1101 is configured as a spherical cavity, the ball head 122 is movably installed in the movable cavity 1101, the ball head 122 can rotate in the movable cavity 1101 around an axis parallel to the supporting shaft 012, and the connecting rod 121 can swing in the movable slot 1102 with the center of the ball head 122 as the center.
[0031] When the methanol generator set 01 vibrates during operation, the supporting shaft 012 at the bottom of the methanol generator set 01 vibrates up, down, left and right at a certain frequency, and the corresponding direction first damper 10 plays a damping role, the shaft cylinder 123 is sleeved on the outside of the supporting shaft 012 to rotate, and the part of the connecting rod 121 connecting the ball head 122 moves in the movable cavity 1101.
[0032] Further, the ball head 122 is provided with a slot 120, which is distributed on one side of the plane along the axis of the supporting shaft 012 and the axis of the connecting rod 121 or symmetrically distributed on both sides of the plane, when the slot 120 is distributed on one side, it is preferably distributed on the upper side to facilitate the replacement of the damping insert 13, and when the slot 120 is distributed on both sides, the corresponding damping insert 13 is installed on both sides.
[0033] In some embodiments, a plurality of slots 120 are provided along the axis direction of the connecting rod 121, and the damping insert 13 is placed in the slot 120, so that when the ball head 122 moves, it extrudes the damping insert 13 inside the slot 120, when the slot 120 is provided on both sides and 3-4 slots are provided on each side, when the ball head 122 is vibrated and swings, the ball head 122 extrudes the damping insert 13 in the area of the slot 120, and the damping insert 13 on both sides can uniformly bear the force and dampen, thereby achieving stable damping effect.
[0034] In this way, according to the different weights of the methanol generator set 01, different numbers, different directions and different damping frequencies of the first damper 10 can be selected and installed in the damping unit 100 to cope with the medium and high frequency vibration during the operation of the methanol generator set 01, and good damping effect can be achieved, and multiple directions of vibration can also be filtered, thereby ensuring the stable operation of the methanol generator set 01 and good noise reduction effect.
[0035] As shown in the figure, Figure 5 andFigure 6 As shown, the damping insert 13 includes an insert seat 131 and a damping pad 132 fixed on one side of the insert seat 131.
[0036] The insert seat 131 is made of stainless steel as a whole, the damping pad 132 is mainly made of butyl rubber or nitrile rubber, forming a rubber damping area, the shell 11 is made of stainless steel as a whole and is a hollow shell, the shell 11 is provided with a groove for mounting the damping insert 13, the insert seat 131 can be detachably mounted in the groove, and the insert seat 131 is provided with a positioning hole 1310, and the shell 11 is provided with a positioning bolt 111 for positioning and fixing the damping insert 13.
[0037] In this way, the damping insert 13 of the vulnerable part can be replaced, and the methanol generator set 01 and the trailer 02 maintain a relative distance, and only the damping insert 13 on the shell 11 needs to be removed, so that the replacement is more simple and fast.
[0038] Meanwhile, the damping pad 132 is provided with a protruding damping insert block 1321 corresponding to the insertion groove 120. When the insert seat 131 is mounted on the shell 11, the damping insert block 1321 on the damping pad 132 is also inserted into the insertion groove 120 on the ball head 122. During the rotation of the ball head 122, the insertion groove 120 on the ball head 122 will extrude the damping insert block 1321 area on the damping pad 132, forming elastic buffering and playing a damping role.
[0039] Further, the insert seat 131 is provided with a core plate 1311 corresponding to each damping insert block 1321 inside. The core plate 1311 is located at the middle position of the damping insert block 1321. In some embodiments, the damping insert block 1321 includes a composite rubber pad layer composed of rubber, polyester fiber or metal sheet distributed from outside to inside, and the metal sheet is the core plate 1311. The stainless steel core plate 1311 plays a role of stable support in the middle part of the damping insert block 1321, avoiding excessive extrusion and deformation of the outer rubber. The outer rubber and polyester fiber composite layer can play a good damping effect and ensure the structural stability of the damping insert block 1321, avoiding excessive deformation and prolonging the service life of the damping insert block 1321 as a whole.
[0040] Further, in order to make the damping block 1321 have better damping effect, the damping block 1321 is provided with a plurality of damping filling blocks 1322 which are uniformly distributed, the thickness of the damping filling block 1322 is greater than that of the damping block 1321, part of the damping filling block 1322 protrudes from the surface of the damping block 1321 to form a stepped structure, when the ball head 122 rotates, part of the damping filling block 1322 is pre-pressed, when the damping filling block 1322 is compressed, the part of the damping block 1321 is pressed, forming two damping areas to provide better damping effect.
[0041] In some embodiments, the hardness of the damping filling block 1322 is less than that of the damping block 1321, the damping filling block 1322 comprises a composite rubber pad block composed of rubber and polyester fiber or metal particles, and the damping filling block 1322 is distributed in a matrix shape on the damping block 1321.
[0042] When the methanol generator set 01 works to generate vibration, the ball head 122 rotates due to the vibration of the methanol generator set 01, and pre-presses the damping filling block 1322 with smaller hardness. In the process of being pressed, the rubber is compressed to the middle and presses the metal particles filled inside, when the damping filling block 1322 is pressed to the same thickness as the damping block 1321, the damping block 1321 and the damping filling block 1322 jointly bear the damping.
[0043] As shown in Figure 5 , the plug seat 131 is provided with a positioning hole 1310, the shell 11 is provided with a positioning bolt 111 corresponding to the plug seat 131, and the plug seat 131 is detachably mounted on the shell 11 through the positioning bolt 111, so as to ensure that the plug seat 131 will not fall off after being mounted on the shell 11.
[0044] As shown in Figure 4 , the bottom side of the shell 11 is provided with a positioning screw seat 112, so that the shell 11 can be detachably mounted on the trailer 02, the elasticity of the rubber pad in each first damper 10 can be different, and the mixed installation on the same damping unit 100 can make the damping unit 100 cope with the medium-high frequency vibration when the methanol generator set 01 works.
[0045] Since the damping unit 100 only plays a role when the methanol generator set 01 works, and when the methanol generator set 01 does not work, the damping unit 100 only plays a role in bearing, and when the trailer 02 walks on the road, the axial bump is transmitted to the methanol generator set 01, the methanol generator set 01 will generate greater pressure to the damping unit 100, thereby accelerating the fatigue aging of the damping unit 100, and even causing irreversible deformation damage to the rubber elements therein, therefore, when the methanol generator set 01 does not work, the damping unit 100 should be separated from the oppression of the methanol generator set 01, thereby playing a protective role on the damping unit 100, so as to prolong the service life of the damping unit 100.
[0046] Further, the device further comprises a jacking device 30, the jacking device 30 is installed between the methanol generator set 01 and the trailer 02, and the jacking device 30 is used to adjust the distance between the methanol generator set 01 and the trailer 02.
[0047] Among them, the jacking device 30 can adopt an electric or manual hydraulic jack, when the methanol generator set 01 works, the height of the jacking device 30 is lowered, so that the methanol generator set 01 and the trailer 02 are elastically connected through the damping unit 100 and the second damper 20, when the methanol generator set 01 does not work, the height of the jacking device 30 is raised, playing a supporting role between the methanol generator set 01 and the trailer 02, directly transmitting the weight of the methanol generator set 01 to the trailer 02, and rigidly connecting the methanol generator set 01 and the trailer 02 through the jacking device 30, so that the damping unit 100 is not affected by the weight, playing a protective role on the damping unit 100.
[0048] It should be noted that, in this text, relational terms such as first and second are used only to distinguish one entity or operation from another, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations. Moreover, the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment.
[0049] The above describes the embodiments, which is not limited, and the drawings only show one of the embodiments, and the actual structure is not limited thereto. In general, if a person skilled in the art is inspired thereby, without departing from the creative purpose, without creative design, similar structure and embodiments of the technical solution can be designed, which shall belong to the protection scope.
