[0019] Beneficial effects of the utility model:

[0020] (1) The utility model supports the load-bearing platform through a support assembly. During long-term operation, the shaft under the load-bearing platform may be damaged. At this time, the shaft needs to be replaced to prevent the load-bearing platform and the equipment from collapsing. When replacing the shaft, the load-bearing platform needs to be supported. At this time, the support column is taken to the load-bearing base, and then the connecting base at the bottom of the support column is clamped into the support base set on the load-bearing base. After the clamping is completed, the lifting screw in the support column is driven to rotate. When rotating, the lifting ring sleeve threaded on the lifting screw will be driven to move up and down, thereby driving the support rod to support the load-bearing platform. After supporting the load-bearing platform, the staff can replace and repair the shaft.

[0021] (2) The utility model fixes the support assembly through a snap-fit ​​assembly. The connecting base at the bottom of the support column is slidably inserted into the support base. During the insertion process, the side wall of the connecting base abuts against the snap-fit ​​block in the support base, thereby squeezing the snap-fit ​​block into the snap-fit ​​box. During the squeezing, the snap-fit ​​spring is also squeezed. When the snap-fit ​​groove on the side wall of the connecting base is in a parallel position with the snap-fit ​​block, the snap-fit ​​spring rebounds and pops the snap-fit ​​block into the snap-fit ​​groove, thereby achieving the effect of snapping the connecting column and preventing the support column from being loosened during support. When the support column needs to be taken away after the support is completed, the staff can pull the pull rod, where two groups of card boxes are provided, and the pull rods in the two groups of card boxes are integrated. When pulled, the pull rod drives the slides in the two groups of card boxes to move toward the top plate, and in the process of moving, the card block is driven to retract into the card box, so that the card block and the card slot are disengaged. After disengagement, the staff can pull out the connecting base and the support column, and then release the pull rod. At this time, the reset spring rebounds, and then drives the card block to pop out of the card box, waiting for the next card connection. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Please see attached picture Figure 1 - Figure 6 As shown, a six-degree-of-freedom load-bearing simulation platform in the embodiment of the utility model includes a load-bearing base 1; an axis 3 arranged on the load-bearing base 1; a load-bearing platform 2 arranged at the end of the axis 3; it is characterized in that it also includes: a support assembly 5 arranged on the load-bearing base 1, used to support the load-bearing platform 2 when replacing the axis 3; a clamping assembly 4 arranged on the side of the support assembly 5, used to fix the support assembly 5; a driving assembly 6 arranged in the middle of the load-bearing base 1, used to drive the support assembly 5 to work; the support assembly 5 includes a support base 58; the support base 58 is fixedly connected to the surface of the load-bearing base 1; a connecting base 52 is clamped in the support base 58; a support column 51 is fixedly connected to the top of the connecting base 52; a lifting screw rod 55 is rotatably connected to the inside of the support column 51; the lifting screw rod 55 rotates by the driving force; a lifting ring sleeve 551 is threadedly connected to the lifting screw rod 55; the side wall of the lifting ring sleeve 551 is fixedly connected to the support rod 53;

[0032] During operation, since various load-bearing simulation devices are placed and installed on the six-degree-of-freedom platform, and their weight is relatively large, during use, if the support shaft under the platform is damaged or the support effect is affected, it will cause the platform to lose support force at a certain point. If the shaft components are not replaced in time, the platform may collapse and cause damage to the platform. In order to prevent such incidents from happening, first, the equipment is placed on the load-bearing platform 2, supported by the shaft body 3 and simulated movements are performed. During long-term work, the shaft body 3 under the load-bearing platform 2 may be damaged. At this time, the shaft body 3 needs to be replaced to In order to prevent the load-bearing platform 2 and the equipment from collapsing, the load-bearing platform 2 needs to be supported when the shaft body 3 is replaced. At this time, the support column 51 is taken to the load-bearing base 1, and then the connecting base 52 at the bottom of the support column 51 is clamped into the support base 58 set on the load-bearing base 1. After the clamping is completed, the lifting screw rod 55 in the support column 51 is driven to rotate. When rotating, the lifting ring sleeve 551 threadedly connected on the lifting screw rod 55 will be driven to move up and down, thereby driving the support rod 53 to support the load-bearing platform 2. After supporting the load-bearing platform 2, the staff can replace and repair the shaft body 3.

[0033] like Figure 1 and Figure 2 As shown, the support column 51 is square; the support column 51 is provided with lifting notches 56 on four sides; the support rod 53 is arranged to pass through the lifting notches 56; and the end of the support rod 53 is fixedly connected with an anti-slip pad 54;

[0034] During operation, the support rod 53 is fixed to the lifting ring sleeve 551, and its end extends to the outside of the support column 51 through the lifting notch 56. When moving up and down, the support rod 53 can be prevented from touching the support column 51, and the end of the support rod 53 is fixed to the anti-skid pad 54, which fits with the bottom of the load-bearing platform 2 to achieve an anti-skid effect.

[0035] like Figure 4 and Figure 5As shown, the clamping assembly 4 includes a clamping box 41; the clamping box 41 is fixedly connected to the side wall of the support base 58; the top of the clamping box 41 is fixedly connected to a top plate 42; a slide plate 45 is slidably connected in the clamping box 41; the end of the slide plate 45 away from the top plate 42 is fixedly connected to a clamping spring 46; the end of the clamping spring 46 is fixedly connected to a clamping block 47; the clamping block 47 is arranged through the support base 58; the end of the slide plate 45 away from the clamping spring 46 is fixedly connected to a pull rod 43; the pull rod 43 is arranged through the top plate 42; the end of the slide plate 45 away from the clamping spring 46 is fixedly connected to a return spring 44; the end of the return spring 44 not connected to the slide plate 45 is fixedly connected to the top plate 42; the clamping assembly 4 is provided with two groups; the pull rods 43 in the two groups of the clamping assemblies 4 are integrally arranged; a clamping groove 59 is opened at the side wall of the connecting base 52 corresponding to the clamping block 47; the inner diameter of the clamping groove 59 is consistent with that of the clamping block 47;

[0036] When working, the connecting base 52 at the bottom of the supporting column 51 is slidably inserted into the supporting base 58. During the insertion process, the side wall of the connecting base 52 will abut against the clamping block 47 in the supporting base 58, thereby squeezing the clamping block 47 into the clamping box 41, and squeezing the clamping spring 46 at the same time. When the clamping groove 59 opened on the side wall of the connecting base 52 is in a parallel position with the clamping block 47, the clamping spring 46 rebounds and pops the clamping block 47 into the clamping groove 59, thereby playing the role of clamping the connecting column to prevent the supporting column 51 from moving during support. After the support is completed, it is necessary to When the support column 51 is taken away, the staff can pull the pull rod 43, where the card-joining box 41 is provided with two groups, and the pull rods 43 in the two groups of card-joining boxes 41 are integrated. When pulling, the pull rod 43 drives the slides 45 in the two groups of card-joining boxes 41 to move toward the top plate 42, and in the process of moving, drives the card-joining block 47 to retract into the card-joining box 41, so that the card-joining block 47 and the card-joining groove 59 are disengaged. After disengagement, the staff can pull out the connecting base 52 and the support column 51. After pulling out, the staff releases the pull rod 43. At this time, the reset spring 44 rebounds, and then drives the card-joining block 47 to pop out of the card-joining box 41, waiting for the next engagement.

[0037] like Figure 3 and Figure 4 As shown, the driving assembly 6 includes a driving base 61; a compression spring 62 is fixedly connected in the driving base 61; a motor base 64 is slidably connected in the driving base 61; a driving motor 65 is fixedly connected to the top of the motor base 64; a driving shaft 66 is rotatably connected to the side wall of the driving motor 65; a driving gear 67 is fixedly connected to the end of the driving shaft 66; a driven gear 57 is fixedly connected to the bottom of the lifting screw rod 55; both the driven gear 57 and the driving gear 67 are bevel gears;

[0038] During operation, after the support column 51 is inserted into the support base 58, the driving motor 65 in the driving assembly 6 is required to drive the lifting screw rod 55 to rotate. The rotation method is: the driving gear 67 set on the side wall of the driving motor 65 is meshed and connected with the driven gear 57 fixed to the bottom of the lifting screw rod 55, and then the driving motor 65 is used to drive the driving gear 67 to rotate, thereby driving the driven gear 57 and the lifting screw rod 55 to rotate. When the support column 51 is inserted into the support base 58, the driving gear 67 and the driven gear 57 are not on the same horizontal line, and the driving gear 67 is higher than the driven gear 57. The two are not in a meshing state. At this time, the staff needs to press the driving motor 65. During the pressing process, the driving gear 67 drops, so that the two are meshed and connected. One set of driving motors 65 drives two groups of support columns 51 to work, which can save electricity resources.

[0039] like Figure 3 As shown, the side wall of the driving base 61 is provided with a clamping module 63; the clamping module 63 is consistent with the internal components of the clamping box 41;

[0040] During operation, after the driving motor 65 is pressed down, the driving base 61 at the bottom of the driving motor 65 will be engaged with the clamping module 63, thereby fixing the driving motor 65. After use, the clamping module 63 is used to disengage the clamp again. After disengagement, the spring 62 is squeezed to rebound, and the driving motor 65 is rebounded again.

[0041] like Figure 1 As shown, the shaft body 3 is spherically connected to the load-bearing base 1 and the load-bearing platform 2; a total of six groups of shaft bodies 3 are provided;

[0042] When working, the spherically connected shaft body 3 can move at multiple angles to achieve movement with multiple degrees of freedom.

[0043] like Figure 1 As shown, the support assembly 5 is provided with two groups; the anti-slip pad 54 is made of rubber;

[0044] During operation, the two groups of support components 5 can support the load-bearing platform 2 at the same time, effectively protecting the load-bearing platform 2, and the anti-skid pad 54 made of rubber material can play an anti-skid effect to avoid slipping during support.

[0045] Working principle of the utility model: Since various load-bearing simulation devices are placed and installed on the six-degree-of-freedom platform, their weight is relatively large. During use, if the support shaft under the platform is damaged or the supporting effect is affected, it will cause the platform to lose its supporting force at a certain point. If the shaft components are not replaced in time, the platform may collapse and cause damage to the platform. In order to prevent such incidents from happening, first, the equipment is placed on the load-bearing platform 2, supported by the shaft body 3 and simulated movements are performed. During long-term work, the shaft body 3 under the load-bearing platform 2 may be damaged. At this time, the shaft body 3 needs to be repaired. Replacement is required to prevent the load-bearing platform 2 and the equipment from collapsing. When replacing the shaft body 3, the load-bearing platform 2 needs to be supported. At this time, the support column 51 is taken to the load-bearing base 1, and then the connecting base 52 at the bottom of the support column 51 is clamped into the support base 58 set on the load-bearing base 1. After the clamping is completed, the lifting screw rod 55 in the support column 51 is driven to rotate. When rotating, the lifting ring sleeve 551 threadedly connected on the lifting screw rod 55 will be driven to move up and down, thereby driving the support rod 53 to support the load-bearing platform 2. After supporting the load-bearing platform 2, the staff can replace and repair the shaft body 3.

[0046] The support assembly 5 is fixed by the snap-fit ​​assembly 4, and the connecting base 52 at the bottom of the support column 51 is slidably inserted into the support base 58. During the insertion process, the side wall of the connecting base 52 will abut against the snap-fit ​​block 47 in the support base 58, thereby squeezing the snap-fit ​​block 47 into the snap-fit ​​box 41, and squeezing the snap-fit ​​spring 46 together. When the snap-fit ​​groove 59 provided on the side wall of the connecting base 52 is in a parallel position with the snap-fit ​​block 47, the snap-fit ​​spring 46 rebounds and pops the snap-fit ​​block 47 into the snap-fit ​​groove 59, thereby achieving the effect of snapping the connecting column and preventing the support column 51 from moving during support. After the support is completed, when the support column 51 needs to be removed, the staff can pull the pull rod 43, where the card box 41 is provided with two groups, and the pull rod 43 in the two groups of card boxes 41 is integrated. When pulling, the pull rod 43 drives the slides 45 in the two groups of card boxes 41 to move toward the top plate 42, and in the process of moving, drives the card block 47 to retract into the card box 41, so that the card block 47 and the card slot 59 are disengaged. After disengagement, the staff can pull out the connecting base 52 and the support column 51. After pulling out, the staff releases the pull rod 43. At this time, the reset spring 44 rebounds, and then drives the card block 47 to pop out of the card box 41, waiting for the next card connection.

[0047] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
