[0021] In order to further understand the content, features and effects of the present invention, the following embodiments are given to explain in detail.

[0022] See also Figure 1 The rocket support bracket with a multifunctional variable diameter device of the present invention includes a movable base device 4, two support seat devices 3 are installed on the base device 4, a roller bracket device 1 is provided above the support seat device 3, and a lifting device 2 is installed between the support seat device 3 and the roller bracket device 1.

[0023] Among them, the base device 4 is used as the base of the entire rocket support bracket, and the two support seat devices 3 are used to support the two elevator devices 2, and the two elevator devices 2 are used to support the two roller bracket devices 1. The two support seat devices 3 can move controllably on the base device 4. When the distance between the two support seat devices 3 decreases, the distance between the two groups of elevator devices 2 and the roller bracket devices 1 decreases. Conversely, when the distance between the two support seat devices 3 increases, the distance between the two groups of elevator devices 2 and the roller bracket devices 1 increases. The two elevator devices 2 are used to drive the two roller bracket devices 1 to move up and down respectively to adjust the height. The roller bracket device 1 has the function of adjusting the effective support diameter. When in use, the rocket compartment 5 is supported by the two roller bracket devices 1.

[0024] See also Figure 3 , we can see that:

[0025] The base device 4 includes a base frame 401 with multiple brake rollers 403, and a base track 405 with two groups of sliders is installed on the base frame 401. The bottoms of the two support seat devices 3 are fixedly connected to the two groups of sliders respectively, and also include a base driving component that drives the two support seat devices 3 to move toward or away from each other.

[0026] As shown in the figure, the base frame 401 is rectangular in shape and is made of welded metal profiles. In order to improve the overall structural strength, a base crossbeam 404 is welded and installed between the middle parts of the two long frames of the base frame 401. There are four brake rollers 403, which are respectively installed and fixed at the bottom of the four corners of the base frame 401. Each brake roller 403 allows the rocket support bracket to move flexibly, and when moving into place, a brake effect is generated by stepping on it to fix the position.

[0027] There are two left and right base rails 405, which are respectively installed and fixed on the upper parts of the two long side frames of the base frame 401. Four sliders are arranged on each base rail 405. The two sliders at the front of the two base rails 405 are a group and are fixedly connected to a support seat device 3, and the two sliders at the rear of the two base rails 405 are a group and are fixedly connected to another support seat device 3.

[0028] In this embodiment, the base driving assembly includes a base plate installed in the middle of both ends of the base frame 401, a base forward and reverse spiral screw 402 is installed between the base plates, a middle shaft seat is installed in the middle of the base cross beam 404 in the middle of the base frame 401, and the middle of the base forward and reverse spiral screw 402 is located in the middle shaft seat. A base handwheel 406 is installed at the end of the base forward and reverse spiral screw 402, and the nut of the forward spiral part of the base forward and reverse spiral screw 402 is fixedly connected to the bottom of one of the support seat devices 3, and the nut of the reverse spiral part is fixedly connected to the bottom of the other support seat device 3. The base forward and reverse spiral screw 402 is driven by the base handwheel 406 to rotate forward or reverse. When rotating forward, the two nuts drive the two support seat devices 3 to move toward each other to reduce the distance. When rotating reversely, the two nuts drive the two support seat devices 3 to move back to each other to increase the distance.

[0029] See also Figure 1 , we can see that:

[0030] The support seat device 3 includes a support bottom plate and a support top plate, a plurality of support vertical plates are welded and installed between the support bottom plate and the support top plate, and a support inclined plate is welded and installed between each support vertical plate and the support bottom plate. The slider of the base device 4 is fixedly connected to the support bottom plate of the support seat device 3 by bolts, and the lift device 2 is installed and fixed on the support top plate of the support seat device 3.

[0031] See also Figure 1 , we can see that:

[0032] The elevator device 2 includes two elevator shells installed on the top of the support seat device 3, and the elevator shells are fixedly connected to the support top plate of the support seat device 3 by bolts. A worm gear assembly is installed in the elevator shell, and the center line of the worm part is in the horizontal direction, and the center line of the worm wheel part is in the vertical direction. The end of the worm is extended from the elevator shell, and the two worms are connected and driven by a linkage shaft, and a lifting handwheel is installed at the outer end of one of the worms. It also includes two left and right lifting screws, the lifting screws pass through the shaft hole in the middle of the worm wheel, and the nut is fixedly connected to the worm wheel, and the roller bracket device 1 is installed and fixed on the upper ends of the two lifting screws.

[0033] By driving the worms of the two worm gear assemblies to rotate synchronously through the lifting handwheel, the two worm wheels rotate synchronously. Since the lifting screws do not rotate, the two lifting screws drive the roller bracket device 1 to move upward or downward.

[0034] In this embodiment, in order to improve the stability of the roller bracket device 1 during lifting and lowering, a guide rod can be installed at the bottom of the roller bracket device 1, and a guide sleeve can be installed in the middle of the supporting top plate of the support seat device 3, so that the lower end of the guide rod is located in the guide sleeve. In this way, when the roller bracket device 1 is lifted and lowered, the stability of the lifting and lowering movement is significantly improved due to the cooperation between the guide rod and the guide sleeve.

[0035] See also Figure 2 , we can see that:

[0036] The roller bracket device 1 includes a bracket base 101 fixedly connected to the top of the elevator device 2. Specifically, the bracket base 101 is fixedly connected to the upper ends of two lifting screws of the elevator device 2 on this side.

[0037] A bracket guide rod 106 with two sets of sliders is installed on the bracket base 101, and also includes a front roller seat 103 and a rear roller seat 108. The bottoms of the two roller seats are fixedly connected to the two sets of sliders respectively. As shown in the figure, the bracket guide rod 106 is provided with two sliders, the two sliders at the front are fixedly connected to the bottom of the front roller seat 103, and the two sliders at the rear are fixedly connected to the bottom of the rear roller seat 108.

[0038] A front supporting roller 104 is installed on the front roller seat 103, and a rear supporting roller 107 is installed on the rear roller seat 108. When in use, the rocket section 5 is placed on the two roller bracket devices 1, and the outer wall of the rocket section 5 contacts the outer walls of the two front supporting rollers 104 and the two rear supporting rollers 107 to obtain stable support.

[0039] In this embodiment, the front support roller 104 and the rear support roller 107 have the same structure and both include a metal roller located inside. A rubber sleeve is provided on the outside of the metal roller and anti-slip grooves are provided on the outer wall of the rubber sleeve. When in use, the outer wall of the rocket compartment 5 contacts the rubber sleeve of each support roller, thereby protecting the outer wall of the rocket compartment 5 to a certain extent.

[0040] It also includes a bracket driving assembly for driving the front roller seat 103 and the rear roller seat 108 to move toward or away from each other.

[0041] In this embodiment, the bracket drive assembly includes a front end base 102 installed at the front end of the bracket base 101 and a rear end base 110 installed at the rear end of the bracket base 101, a bracket forward and reverse spiral screw 105 is installed between the front end base 102 and the rear end base 110, the bracket forward and reverse spiral screw 105 is located between two bracket guide rods 106, and a bracket handwheel 109 is installed at the end of the bracket forward and reverse spiral screw 105, the nut of the forward spiral part of the bracket forward and reverse spiral screw 105 is fixedly connected to the bottom of the front roller seat 103, and the nut of the reverse spiral part is fixedly connected to the bottom of the rear roller seat 108.

[0042] When the forward and reverse spiral screw 105 is driven to rotate forwardly by the bracket hand wheel 109, the front roller seat 103 and the rear roller seat 108 move toward each other to reduce the distance, and the effective support diameter is reduced. Conversely, when the forward and reverse spiral screw 105 is driven to rotate reversely by the bracket hand wheel 109, the front roller seat 103 and the rear roller seat 108 move away from each other to increase the distance, and the effective support diameter is increased.

[0043] For usage, see Figure 4 :

[0044] The support bracket is structurally adjusted and set according to the length and diameter of the rocket compartment 5, the base drive assembly is operated to increase or decrease the distance between the two support seat devices 3, and the bracket drive assembly is operated to increase or decrease the distance between the front roller seat 103 and the rear roller seat 108 of each roller bracket device 1; the elevator device 2 is operated to adjust the height of the rocket compartment 5;

[0045] The supporting bracket is then pushed and moved to align the end of the rocket segment 5 with the end of the segment to be assembled. If the height is not appropriate, the two lifting devices 2 are operated to fine-tune the height of the rocket segment 5 to make the center lines of the segments collinear. During assembly, if the connection points between the segments are not aligned laterally, the rocket segment 5 can be rotated and fine-tuned to align the connection points to facilitate the setting of fastening parts.
