[0028] On the one hand, please refer to Figures 1 to 4The embodiment provides a support device 1 for limiting the support height of a slewing arm 2, the support device 1 comprising a fixing part 11 for being connected with a rack 4, and a plurality of support parts 12 for supporting the slewing arm 2, wherein the plurality of support parts 12 have different support heights, and the plurality of support parts 12 are selectively installed on the fixing part 11. In this way, by selectively installing the support parts 12 with different support heights on the fixing part 11, the support device 1 can be used according to the actual operation of the equipment, and the support height of the support device 1 can be changed by replacing the support parts 12 with different support heights, thereby increasing the application range of the support device 1.
[0029] In some embodiments, any two of the plurality of support parts 12 are detachably connected in the vertical direction. In this way, the support device 1 can flexibly install or detach the support parts 12, thereby adjusting the support height to adapt to different working requirements of the equipment, and meanwhile, the detachable connection makes the installation and detachment of the support parts 12 more convenient and fast, thereby reducing the installation time.
[0030] Optionally, referring to Figure 1 , the support part 12 has a support surface 121 for being attached to the outer circumferential surface of the slewing arm 2. In this way, the support surface 121 is attached to the outer circumferential surface of the slewing arm 2, thereby increasing the contact area between the support part 12 and the slewing arm 2, thereby increasing the stability of the support, and reducing the sliding or displacement caused by poor contact; meanwhile, the attached support surface 121 can avoid the abrasion caused by the collision and friction between the slewing arm 2 and the support device 1 during the movement of the slewing arm 2, thereby prolonging the service life of the equipment.
[0031] Optionally, the support surface 121 is provided with a buffer pad. In this way, the buffer pad has a buffering effect, and when the slewing arm 2 contacts the support device 1, the buffer pad is elastically deformed to absorb part of the impact force, thereby reducing the abrasion caused by the contact between the slewing arm 2 and the support device 1. Preferably, the buffer pad is made of rubber material. In other embodiments, the buffer pad can also be a foam buffer pad or an air cushion buffer pad.
[0032] Preferably, the support surface 121 is a circular arc surface. In other embodiments, the support surface 121 can also be V-shaped, etc. In this way, the tapered support surface 121 can better adapt to slewing arms 2 of different sizes, thereby ensuring that the slewing arm 2 can be at least partially supported on the support surface 121, and finally guided to the center of the slewing arm 2 on the support surface, so that the support device 1 can more stably support the slewing arm 2.
[0033] On the other hand, referring to Figure 3 and Figure 4The embodiment provides a rotary structure, which comprises an external part and the support device 1, the external part comprises a rotary arm 2, a rotary shaft 3 and a rack 4, the rotary shaft 3 is fixedly connected to the rack 4, the rotary arm 2 is rotationally arranged on the rotary shaft 3, the fixing part 11 is connected to the rack 4, and the fixing part 11 is arranged on the rotary shaft 3 and located on a rotation path of the rotary arm 2. In this way, by installing the support device 1 on the rack 4, the fixing part 11 of the support device 1 is arranged on the rotation path of the rotary arm 2, so that the rotary arm 2 can be supported on the supporting part 12 of the support device 1 during rotation, thereby limiting the support height of the rotary arm 2, avoiding collision between the rotary arm 2 and a feeding vehicle due to too low position of the rotary arm 2, and damage to the machine, or too high position of the rotary arm 2, so that an operator cannot perform a material replacement operation.
[0034] It should be understood that the support height of the supporting part 12 is not limited in the embodiment, and the supporting part 12 with different support heights can be selected and installed on the fixing part 11 according to actual work needs of the rotary arm 2.
[0035] Optionally, referring to Figure 4 The rack 4 comprises a rack body 41 and a base 42 protruding from a side wall of the rack body 41, the fixing part 11 comprises a connecting part 111 and a supporting part 112, the connecting part 111 is supported above the base 42, and the connecting part 111 is fixed to the rack 4 through a fastener, the supporting part 112 is connected above the connecting part 111 and is used for being connected with the supporting part 12, and a bottom surface of the supporting part 112 abuts against a top surface of the rack body 41 in a vertical direction. In this way, the fixing part 11 of the support device 1 is supported by the rack body 41 and the base 42 at the same time, so that the support stability of the support device 1 is ensured.
[0036] Optionally, the fixing part 11 further comprises a wedge-shaped block 113 fixedly connected with the connecting part 111, the wedge-shaped block 113 and the rotary shaft 3 are located on two sides of the connecting part 111 respectively, and the wedge-shaped block 113 abuts against the base 42 in the vertical direction. In this way, during the rotation of the rotary arm 2, an impact force in the rotation direction of the rotary arm 2 is applied to the support device 1 by the contact between the rotary arm 2 and the support device 1, the wedge-shaped block 113 and the rotary shaft 3 are located on two sides of the connecting part 111 respectively, and the wedge-shaped block 113 abuts against the base 42 in the vertical direction, so that the support device 1 is prevented from falling due to the impact force, and the support stability of the support device 1 is further ensured.
[0037] Optionally, referring to Figures 2 to 4The connecting part 111 and the rotating shaft 3 are located on both sides of the frame 4, the fastener is a bolt, and the bolt extends in the horizontal direction. In this way, when the rotating arm 2 is supported on the supporting device 1, the supporting device 1 is subjected to a pressure perpendicular to the direction of the rotating arm 2, which can be decomposed into a first pressure in the vertical direction and a second pressure in the horizontal direction. The bolt extends in the horizontal direction, so that it can bear the second pressure in the axial direction, avoids deformation of the bolt due to bending moment, ensures stable connection of the supporting device 1 to the frame 4, and provides support for the rotating arm 2, thereby ensuring the reliability of the rotating structure. In other embodiments, the fastener can also be a pin.
[0038] Optionally, the connecting part 111, the supporting part 112 and the wedge block 113 are integrally arranged. In this way, the mounting and dismounting process of the fixing part 11 is simplified, the dismounting efficiency is improved, and the maintenance of the device is facilitated.
[0039] The supporting device 1 and the rotating structure provided by the embodiment can be applied to an opener. One end of the rotating arm 2 is rotationally connected with the rotating shaft 3, and the other end is suspended and provided with a feeding port. The opener has an opening state and a material changing state. In the opening state, the feeding port of the rotating arm 2 is in a high position, and at this time, the opener performs opening treatment on the tow in the feeding port. In the material changing state, the rotating arm 2 is rotated by the rotating shaft 3 to abut the supporting surface 121 of the supporting device 1 with the outer circumferential surface of the rotating arm 2. At this time, the rotating arm 2 is supported on the supporting device 1 and cannot continue to rotate. At this time, the feeding port of the rotating arm 2 is in a low position, which facilitates the material changing operation of the operator. By adjusting the supporting height of the supporting device 1, the low position of the rotating arm 2 can be prevented from being too low to collide with the feeding trolley and damage the machine, or the low position of the rotating arm 2 can be prevented from being too high to cause the operator to be unable to perform the material changing operation.
[0040] In other embodiments, the supporting device 1 and the rotating structure can also be applied to various mechanical equipment, such as a crane, a revolving door, etc.
