[0025] In order to better understand the technical scheme of the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings.
[0026] It should be noted that the embodiments in the present application and the features and technical solutions in the embodiments can be combined with each other without conflict.
[0027] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.
[0028] Embodiment 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , a kind of anti-loose pressure heavy load ton bucket beam structure, dome block 203 is slidably arranged on dome groove 204, spring one 206 is arranged on the corresponding surface of sliding ring 205 and support disc 202; In use, as shown in Figure 1 , the existing frame is installed on support disc 202, and the existing ton barrel is placed in the frame, the existing ton barrel is fixed by support disc 202 and the existing frame, so that the existing ton barrel is fixed on base 1, support disc 202 is positioned in offset slot 201 by the elasticity of spring one 206, the existing frame and ton barrel are horizontal with base 1, when the existing ton barrel is transported and different direction vibration occurs, the center of gravity of ton barrel changes, the center of gravity of ton barrel changes and drives support disc 202 and dome block 203 to rotate along dome groove 204, spring one 206 corresponding to the deflection direction of support disc 202, dome block 203, existing frame and ton barrel is extruded and shrunk, the existing ton barrel is buffered by the extension of spring one 206, so that when the existing ton barrel is subjected to different direction vibration, support disc 202 and dome block 203 will adaptively rotate with different direction vibration, and different direction vibration is buffered by spring one 206, so as to reduce the impact force generated by the violent shaking of the liquid or solid material in the existing ton barrel, prevent the deformation or damage of the connecting part of base 1, existing frame and support disc 202 due to excessive stress, thereby improving the service life of the equipment; Further, threaded rod 207 is rotatably arranged in base 1, sliding ring 205 is threadedly connected to threaded rod 207, guide block 208 is arranged in offset slot 201, and sliding ring 205 is slidably arranged on guide block 208; Guide block 208 is used to guide sliding ring 205. When threaded rod 207 rotates, threaded rod 207 drives sliding ring 205 to slide along guide block 208, such as... Figure 2 As shown, when the sliding ring 205 slides upward along the guide block 208, the spring 206 is compressed and contracted by the sliding ring 205 and the support plate 202. At this time, the elasticity of the spring 206 increases. Similarly, when the sliding ring 205 slides downward, the spring 206 unfolds and the elasticity of the spring 206 decreases. By changing the elasticity of the spring 206, the existing ton can be buffered in a targeted manner. The shock absorption effect can be optimized according to the actual load of the existing ton, thus improving the stability of the equipment. When the ton is heavy, the elasticity of the spring 206 is increased; when the ton is light, the elasticity of the spring 206 is decreased. When the elasticity of spring-206 is high, a larger force is required to deform it, which is suitable for heavy load conditions. When the existing ton container is relatively light, vibration is easily transmitted to the ton container. When the elasticity of spring-206 is low, a smaller force is enough to deform it, which is suitable for light load conditions. When the existing ton container is relatively heavy, it cannot effectively cushion the ton container. Furthermore, a stop 209 is provided inside the base 1. The stop 209 is wedge-shaped and is adapted to the support plate 202. The stop 209 is used to limit the support plate 202. When the support plate 202 rotates and contacts the stop 209, the stop 209 limits the support plate 202 to prevent the support plate 202 from deflecting too much. At the same time, the existing frame does not contact the base 1 when rotating synchronously with the support plate 202, thus preventing the existing frame from colliding with the base 1 when rotating. Furthermore, a drive gear 210 is provided on the threaded rod 207, and a transmission gear 211 is rotatably provided inside the base 1. The drive gear 210 and the transmission gear 211 are matched, and a worm gear 212 is provided on the transmission gear 211. The worm gear 212 is rotatably provided on the base 1. Furthermore, a worm gear 213 is rotatably mounted on the base 1, and the worm gear 213 is adapted to the worm wheel 212. A knob 214 is mounted on the worm gear 213. When the knob 214 is rotated, the knob 214 drives the worm gear 213 to rotate synchronously. The worm gear 213 drives the worm wheel 212 to rotate, the worm wheel 212 drives the transmission gear 211 to rotate, the transmission gear 211 drives the drive gear 210 to rotate, and the drive gear 210 drives the threaded rod 207 to rotate. By limiting the worm wheel 212 with the worm gear 213, the worm wheel 212 cannot rotate when the worm gear 213 is not rotating, and consequently the threaded rod 207 cannot rotate either. This prevents the sliding ring 205 from becoming loose. The spring 206 is driven by the synchronous adjusting mechanism 2 to buffer the existing ton barrel, and the supporting disc 202 is self-adaptive rotation to realize buffering of vibration in different directions, prevent deformation and damage of the equipment, and improve the service life of the equipment. By changing the elasticity of the spring 206, the existing ton barrel can be buffered in a targeted manner, the damping effect can be optimized according to the actual load of the existing ton barrel, and the stability of the equipment is improved.
[0029] In embodiment 2, the beam structure for the anti-loosening pressure-resistant heavy-load ton barrel provided in embodiment 1 is further optimized, and specifically, as shown in Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 , a cavity 215 is arranged in the sliding ring 205, a jacking column 216 is arranged in the cavity 215 in a sliding manner, the end of the jacking column 216 is semicircular, a limiting groove 217 is arranged in the base 1, the end of the jacking column 216 is matched with the limiting groove 217, a spring 218 is arranged in the cavity 215, the jacking column 216 is positioned in the limiting groove 217 through the elasticity of the spring 218, when the existing ton barrel is subjected to severe vibration, the spring 206 is deformed and pressure is applied to the sliding ring 205, when the pressure is applied to the sliding ring 205, the applied pressure is supported by the jacking column 216, so that the pressure applied to the threaded rod 207 is reduced, and the threaded rod 207 and the sliding ring 205 are prevented from being damaged due to excessive pressure; Further, the limiting groove 217 is provided with a plurality of limiting grooves 217, and the plurality of limiting grooves 217 are arranged in the base 1 in a linear array, when the sliding ring 205 slides along the guide block 208, the jacking column 216 and the sliding ring 205 slide synchronously, and when the sliding ring 205 stops sliding, the jacking column 216 can be quickly matched with the limiting groove 217; Further, a driving ring 219 is arranged in the cavity 215, and the spring 218 is arranged on the corresponding surface of the driving ring 219 and the cavity 215, when the sliding ring 205 slides, the jacking column 216 and the limiting groove 217 continuously perform disengagement and engagement movements, as shown in Figure 5 , at this time, the driving ring 219 continuously reciprocates left and right, when the driving ring 219 slides and resets, the sliding ring 205 slides and hits the cavity 215, so that the sliding ring 205 vibrates, because the spring 206 has a continuous downward pressure on the sliding ring 205, the sliding ring 205 will be affected by pressure during movement, these pressures will increase the resistance of the sliding ring 205 during movement, the pressure will increase the friction between the sliding ring 205 and the threaded rod 207, the small displacement generated by the vibration of the sliding ring 205 can change the contact point between the sliding ring 205 and the threaded rod 207, so that the sliding resistance of the sliding ring 205 is reduced, and the jamming phenomenon caused by pressure is reduced; Further, the base 1 is provided with an extension 220, the extension 220 is matched with the sliding ring 205, the sliding ring 205 is limited by the extension 220, and the sliding ring 205 is prevented from being separated from the threaded rod 207; The synchronous adjusting mechanism 2 drives the sliding ring 205 to vibrate, so that the sliding resistance of the sliding ring 205 is reduced, the jamming phenomenon caused by pressure is reduced, and the internal parts are prevented from being jammed due to long-term use of the equipment.
[0030] The use process of the anti-loosening pressure-resistant heavy-load cross beam structure for a ton barrel is as follows: In use, the existing frame is installed on the support disc 202, and the existing ton barrel is placed in the frame, and the existing ton barrel is fixed by the support disc 202 and the existing frame, so that the existing ton barrel is fixed on the base 1. When the existing ton barrel is transported and subjected to vibration in different directions, the center of gravity of the ton barrel changes, and the support disc 202 and the dome block 203 are driven to rotate along the dome groove 204. At this time, the spring one 206 corresponding to the deflection direction of the support disc 202, the dome block 203, the existing frame and the ton barrel is squeezed and contracted. The existing ton barrel is buffered by the extension and contraction of the spring one 206, so that the support disc 202 and the dome block 203 will adaptively rotate with the vibration in different directions, and the spring one 206 will buffer the vibration in different directions. This reduces the impact force generated by the violent shaking of the liquid or solid material in the existing ton barrel. When the rotating knob 214 is rotated, the knob 214 drives the worm 213 to rotate synchronously, the worm 213 drives the worm wheel 212 to rotate, the worm wheel 212 drives the transmission gear 211 to rotate, the transmission gear 211 drives the drive gear 210 to rotate, and the drive gear 210 drives the threaded rod 207 to rotate. The threaded rod 207 drives the sliding ring 205 to slide along the guide block 208, wherein the top column 216 and the limiting groove 217 continuously move away from and engage with each other. At this time, the drive ring 219 continuously slides left and right, and when the drive ring 219 slides back to its original position, the sliding ring 205 slides and hits the cavity 215, causing the sliding ring 205 to vibrate. Because the spring one 206 has a constant downward pressure on the sliding ring 205, the sliding ring 205 will be affected by the pressure during movement. These pressures will increase the resistance of the sliding ring 205 when it moves. The pressure will increase the friction between the sliding ring 205 and the threaded rod 207. The slight displacement caused by the vibration of the sliding ring 205 can change the contact point between the sliding ring 205 and the threaded rod 207, reducing the resistance of the sliding ring 205. This reduces the jamming phenomenon caused by pressure. When the sliding ring 205 slides upward along the guide block 208, the spring one 206 is squeezed and contracted by the sliding ring 205 and the support disc 202. At this time, the elasticity of the spring one 206 increases. Similarly, when the sliding ring 205 slides downward, the spring one 206 expands. At this time, the elasticity of the spring one 206 decreases. By changing the elasticity of the spring one 206, the existing ton barrel can be buffered in a targeted manner. The actual load of the existing ton barrel can be used to optimize the shock absorption effect.
