[0021] The technical solutions of the present invention are further described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1 to 3As shown, an embodiment of the present invention proposes a steel structure grid hemispherical support sliding installation construction support device, including a guide rail 1 and a reinforcement assembly, there are two guide rails 1, the two guide rails 1 are arranged opposite to each other, and a support frame 2 for supporting the steel structure grid is provided between the two guide rails 1, the support frame 2 includes a plurality of support rods 201 and a plurality of connecting balls 202, each support rod 201 has a slot at both ends, and each connecting ball 202 has a plurality of connecting columns 203 on the circumferential outer wall at equal intervals along the direction away from the center of the ball, each connecting column 203 is adapted to the slot of the support rod 201, and the support rods 201 are connected by the connecting balls 202 to form a support frame 2, there are a plurality of reinforcement assemblies, and the reinforcement assemblies are arranged between two adjacent connecting balls 202, and the reinforcement assemblies are used to improve the overall strength of the support frame 2. Before assembling the steel structure grid, first set up the guide rail 1 at the predetermined position. The guide rail 1 is used for the steel structure grid to slide, and the support frame 2 is assembled between the two guide rails 1. Specifically, the support frame 2 is a multi-layer frame assembled by connecting multiple horizontal and vertical support rods 201 through connecting balls 202. In this embodiment, the frame has three layers. The support rods 201 at the bottom are pre-buried in the ground to connect them to the ground to improve the stability of the frame. Then, a connecting ball 202 is inserted into the top of the support rod 201 through the cooperation of the connecting column 203 and the slot. There are multiple connecting columns 203 on the outer wall of the connecting ball 202. In this embodiment, four connecting columns 203 are evenly spaced in the horizontal direction of the connecting columns 203, with one connecting column 203 at the top and one at the bottom, for a total of six connecting columns 203. The support rods 201 and the connecting balls 202 are connected in sequence in the longitudinal direction to finally form a support frame 2. As needed, a reinforcement component is connected between two adjacent connecting balls 202 to form a triangular support between the reinforcement component and the horizontal support rods 201 and the vertical support rods 201, thereby improving the stability of the entire support frame 2 and providing sufficient supporting strength for the steel structure grid assembled thereon. Through this device, when assembling the support frame 2 supporting the steel structure grid, the various components of the support frame 2 are modularized, and the support rods 201 are connected by connecting balls 202. There is no need to use a large number of bolts. The slots and connecting columns 203 cooperate to plug and connect the support rods 201 and the connecting balls 202 to form a frame body, which ensures that the support frame 2 does not shake, greatly saves the time of assembling the support frame 2, and indirectly improves the efficiency of making the steel structure grid.

[0023] like Figure 3As shown, further, each reinforcement assembly includes: a diagonal brace 3, each end of which is hingedly provided with a mounting post 5 via a ball joint 4, and each connecting ball 202 is provided with a connecting hole 6 for connecting the mounting post 5. The ball joint 4 is provided at both ends of the diagonal brace 3. When installing the diagonal brace 3, the mounting post 5 on one end of the diagonal brace 3 is first connected to the connecting hole 6 on the connecting ball 202, and then the diagonal brace 3 is tilted and the other end of the diagonal brace 3 is connected to the connecting ball 202 on the other row, so that a horizontal support rod 201 and a vertical support rod 201 form a triangular stable structure. The diagonal brace 3 can be installed wherever needed in the entire support frame 2, thereby ensuring the stability of the entire support frame 2. Preferably, the diagonal brace 3 is a telescopic structure.

[0024] like Figure 3 As shown, each diagonal brace 3 further comprises two reinforcing rods 301 and a sleeve 302. The two reinforcing rods 301 are respectively threaded to the ends of the sleeve 302. Each reinforcing rod 301 is hingedly provided with a mounting post 5 at one end facing away from the sleeve 302 via a ball joint 4. In this embodiment, to facilitate installation of the diagonal brace 3, the mounting post 5 at one end of the diagonal brace 3 is pre-connected with the connecting hole 6 by twisting the two reinforcing rods 301. Once connected, the mounting post 5 at the other end is aligned with the connecting hole 6 of the other connecting ball 202. The support rod 201 is then rotated to align the mounting post 5 at that end with the connecting hole 6. The mounting post 5 can be connected to the connecting hole 6 by either a snap-on or a threaded connection.

[0025] like Figure 3 As shown, further comprising a stepping plate 7, each support rod 201 has a square cross-section, and the stepping plate 7 is horizontally mounted between two adjacent support rods 201. In this embodiment, the support rods 201 are in the shape of strip columns, and the top surfaces of two adjacent support rods 201 can form a plane, on which a footrest is mounted, so that workers can step on the footrest to assemble the steel structure grid.

[0026] like Figure 3 As shown, the cross section of the pedal board 7 is concave. The pedal board 7 has a concave structure. When the pedal board 7 is installed, the pedal board 7 takes on an inverted concave shape. The grooves of the concave pedal board 7 are respectively stuck on the two support rods 201, and the inner sides of the two wing plates of the pedal board 7 are respectively in contact with the outer sides of the support rods 201, thereby limiting the shaking of the pedal board 7 and ensuring the safety of workers when working on the pedal board 7.

[0027] like Figure 4As shown, further, it also includes: a winch 8, the winch 8 is fixedly provided at the same end of each guide rail 1, two pull ropes 9 are convoluted on the output end of the winch 8, and a hook is provided on the free end of each pull rope 9. A sliding seat 10 is slidably provided at the end of each guide rail 1 away from the winch 8, and a clamping ring 11 is symmetrically provided at both ends of the sliding seat 10, and the hook is clamped with the clamping ring 11. Specifically, the clamping ring 11 is provided on the end face of the sliding seat 10 facing the winch 8. When a steel structure grid is assembled, the steel structure grid needs to be slid. The hemispherical support of the steel structure grid is slidably provided on the guide rail 1. When sliding the steel structure grid, the hook of the pull rope 9 is clamped on the clamping ring 11 of the sliding seat 10. When the winch 8 reels the pull rope 9, it pulls the sliding seat 10 to move, so that the sliding seat 10 pushes the steel structure grid to slide, thereby playing an auxiliary pushing role.

[0028] like Figure 4 As shown, the structure further includes a connecting rod 12, one end of which is connected to the sliding seat 10, and the other end of the connecting rod 12 is provided with a curved plate 13, one end of which is provided with a clamping strip 14, and the other end of the curved plate 13 is provided with a locking assembly for locking the clamping strip 14 thereto. The curved plate 13 is adapted to the rods of the steel structure grid. Before pushing, one end of the clamping strip 14 is first passed around the rods of the steel structure grid, and then the clamping strip 14 is locked and fixed by the locking assembly, thereby fastening the steel structure grid to the sliding seat 10, ensuring that the sliding seat 10 can stably push the steel structure grid.

[0029] like Figure 5 As shown, the locking assembly further includes: a mounting block 15, a through slot for the clip 14 to pass through, a mounting slot connected to the through slot on the side wall of the mounting block 15, a pressure plate 16 slidably disposed in the mounting slot, a pull rod 17 disposed at the end of the pressure plate 16 facing away from the through slot, a pull ring 18 disposed at the end of the pull rod 17 facing away from the pressure plate 16 and extending out of the mounting slot, a spring 19 also sleeved on the pull rod 17, one end of the spring 19 connected to the pressure plate 16, and the other end of the spring 19 fixedly connected to the inner wall of the mounting slot. When locking and fixing the clip 14, the pull ring 18 is pulled outward, causing the pull rod 17 to drive the pressure plate 16 to overcome the friction of the spring 19 and move, and then the free end of the clip 14 is inserted into the through slot. At this time, the pull ring 18 is released, and the spring 19 pushes the pressure plate 16 to abut against the side wall of the clip 14, restricting the movement of the clip 14. Preferably, the spring 19 is a spring 19 with a large elastic coefficient to avoid large deformation of the spring 19 under a small external force.

[0030] like Figure 5 As shown, further, a plurality of limiting strips 20 are evenly spaced on each pressing plate 16, and a plurality of inserting strips 21 are provided on the side of the clamping strip 14 facing the pressing plate 16. The clamping engagement of the inserting strips 21 with the limiting strips 20 effectively prevents the clamping strip 14 from loosening from the through slot during use.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
