Description

Technical Field

[0001] The present invention relates to the technical field of steel structure assembly, and more particularly to a steel truss assembly frame assisted by sliding support. Background Art

[0002] The steel truss assembly frame assisted by sliding support mainly has the function of sliding support through the sliding support structure on the frame, which makes the assembly of the steel truss more flexible and efficient. Secondly, the construction workers can quickly adjust the position and size of the frame as needed.

[0003] Patent publication number CN107939053A discloses a precisely adjustable steel truss assembly cradle. During operation, the cradle primarily operates by tightening and loosening a nut, allowing a T-shaped slide to slide vertically along a vertical seam. Rotating a knob causes a stopper to slide horizontally along a sliding groove. This assembly cradle accommodates trusses of various sizes, improving installation precision, project quality, and economic benefits. However, this technology still presents the following challenges.

[0004] During the assembly process of the steel truss, auxiliary positioning support is mainly provided to the steel truss through the assembly cradle. Although external positioning auxiliary support can be provided to realize assembly construction, the internal structure of the steel truss has inclined assembly positions at different points. This requires external positioning assembly, and then multiple internal points are assembled and supported one by one at different angles. The efficiency of the assembly assistance at multiple points is low, so it is difficult to realize synchronous assembly support at multiple internal points according to different inclined positions, resulting in low efficiency of steel truss assembly support. Therefore, a steel truss assembly cradle with sliding support assistance is required. Summary of the Invention

The outer wall of the inclined slot column is slidably connected with a sleeve slider, and a gap is provided between the sleeve slider and the inclined inner support plate; a T-shaped bar is fixedly connected between two adjacent sleeve sliders, and the T-shaped bar is fixedly connected to the positioning outer slot frame.

[0007] When assembling the sliding support, the linkage strip drives the multiple hinged strips to the left, which in turn drives the two linkage columns to the left. The sleeve strip drives the linkage shaft, and the inclined slot column moves along the inner wall of the sleeved slider. The inclined slot column drives the inclined inner support plate to move. The two inclined inner support plates inside the multiple positioning outer slot frames on the right side move synchronously, while the two inclined inner support plates inside the multiple positioning outer slot frames on the left side also move synchronously. In this way, the multiple inclined inner support plates can be synchronously moved at different inclination angles to the splicing support position inside the steel truss.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] As attached Figure 1 - Attachment Figure 9 The steel truss assembly frame shown is assisted by a sliding support. The steel truss assembly frame assisted by a sliding support is provided with an internal multi-point inclined synchronous support mechanism, a multi-point internal linkage support component and a synchronous transmission component. The settings of each mechanism and component can enable multiple inclined internal support plates 8 to move synchronously to the internal splicing support position of the steel truss at different inclination angles, realize internal multi-point inclined synchronous sliding support, and greatly improve the assembly support efficiency of the steel truss. The specific structural settings of each mechanism and component are as follows.

[0028] In this technical solution, as shown in the attached Figure 1 - Attachment Figure 5 As shown, each base frame 1 is fixedly connected to the top of two support frames 2. One side of the support frame 2 is equipped with an internal multi-point tilting synchronous support mechanism. The internal multi-point tilting synchronous support mechanism includes a hinge bar 3 slidably connected to one side of the support frame 2. Two linkage columns 4 are fixedly connected to the interior of the hinge bar 3. The outer wall of each linkage column 4 is rotatably connected to a sleeve bar 5. A linkage shaft 6 is rotatably connected to the inner wall of the sleeve bar 5, away from the linkage column 4. One end of the linkage shaft 6 is fixedly connected to an inclined slot column 7. One end of the inclined slot column 7 is fixedly connected to an inclined inner support plate 8. The outer wall of the inclined inner support plate 8 is equipped with a positioning outer slot frame 9. Both inclined inner support plates 8 are slidably connected to the positioning outer slot frame 9. The two linkage columns 4 are symmetrically arranged about the center of the hinge bar 3 and have a circular vertical cross-section. The outer walls of the hinge bar 3 and the outer walls of the support frame 2 are smooth. The inclined slot columns 7 and the hinge bar 3 are both rotatably connected to the sleeve bar 5. The two inclined slot columns 7 are symmetrically arranged about the center of the hinge bar 3.

[0029] In this technical solution, as shown in the attached Figure 4 --Attachment Figure 6 As shown, the support frame 2 is fixedly connected to the positioning outer trough frame 9, and a reinforcement plate 10 is fixedly installed on the upper surface of the positioning outer trough frame 9; the outer wall of the hinge bar 3 is slidably connected to a sliding frame 21, and the sliding frame 21 is fixedly connected to the support frame 2. A distance sensor 11 is fixedly installed on the top of one of the sliding frames 21, and the controller 29 is electrically connected to the distance sensor 11. A sensing block 12 is provided on one side of the distance sensor 11, and the sensing block 12 is fixedly connected to the hinge bar 3. Two positioning bottom bars 13 are installed on the upper surface of the base frame 1 and located on one side of the positioning outer trough frame 9. Both positioning bottom bars 13 are fixedly connected to the base frame 1, so that the bottom of the steel truss can be docked in the gap between the two positioning bottom bars 13 to achieve positioning support for the bottom of the steel truss.

[0030] The outer wall of the inclined groove column 7 is slidably connected with a sleeve slider 14, and a gap is provided between the sleeve slider 14 and the inclined inner support plate 8; a T-shaped bar 15 is fixedly connected between two adjacent sleeve sliders 14, and the T-shaped bar 15 is fixedly connected to the positioning outer groove frame 9 to facilitate the inclined groove column 7 to move along the inner wall of the sleeve slider 14. The T-shaped bar 15 supports the sleeve slider 14, and the sleeve slider 14 can ensure that the inclined groove column 7 moves stably.

[0031] In this technical solution, as shown in the attached Figure 4 - Attachment Figure 6 As shown, the upper surface of the hinge bar 3 is provided with a multi-point internal linkage support assembly; the multi-point internal linkage support assembly includes a linkage bar 16 fixedly mounted on the upper surface of the hinge bar 3, and an L-shaped bar 17 is fixedly connected to the top of the linkage bar 16. A support bar 18 is fixedly mounted on one side of the inner wall of the L-shaped bar 17; one end of the support bar 18 is fixedly connected to a support inner block 19, and a concave inclined plate 20 is fixedly mounted on the top of the L-shaped bar 17. The vertical cross-section of the concave inclined plate 20 is concave. The support inner block 19 and the concave inclined plate 20 are both slidably connected to the positioning outer channel frame 9. The outer walls of the concave inclined plate 20 and the support inner block 19 are both smooth.

[0032] In this technical solution, as shown in the attached Figure 7 - Attachment Figure 9As shown, a support frame 22 is fixedly mounted on one side of one of the base frames 1. A synchronous transmission assembly is provided inside the support frame 22. The synchronous transmission assembly includes a linkage screw 23 that is rotatably connected to the support frame 22. The outer wall of the linkage screw 23 has two opposite and symmetrical threads. Two socket blocks 24 are threadedly connected to the outer wall of the linkage screw 23. The top of each socket block 24 is fixedly connected to a pressure strip 25. One end of the pressure strip 25 is fixedly mounted with a linkage block 26. The top of the linkage block 26 is fixedly connected to a linkage strip plate 27. Multiple hinge bars 3 are fixedly connected to the linkage strip plate 27. A reduction motor 28 is fixedly mounted on one end of the support frame 22. The output end of the reduction motor 28 is fixedly connected to the linkage screw 23. A controller 29 is electrically connected to the reduction motor 28. Both socket blocks 24 are slidably connected to the support frame 22. The outer wall of the socket block 24 and the inner wall of the support frame 22 are smooth. The reduction motor 28 is used to drive the linkage screw 23 to rotate.

[0033] The method of using the slidably supported steel truss assembly cradle of the present invention is as follows:

[0034] First, when the present invention positions and assembles the outer steel trusses, the bottom of the steel truss is docked in the gap between the two positioning bottom bars 13, and the bottom of the steel truss is provided with supporting force by the base frame 1, while the two positioning outer trough frames 9 on the base frame 1 provide positioning and supporting functions for both sides of the outer wall of the steel truss. The base frame 1 supports the support frame 2, and the support frame 2 increases the supporting stability of the positioning outer trough frame 9. The reinforcement plate 10 is then supported by the support frame 2, and the reinforcement plate 10 supports the positioning outer trough frame 9, thereby continuing to increase the stability of the positioning outer trough frame 9.

[0035] Secondly, during synchronous transmission, the controller 29 activates the reduction motor 28, which drives the linkage screw 23 to rotate. The linkage screw 23 rotates within the support frame 22, and the linkage screw 23 drives the two connecting blocks 24 toward each other under the action of the threaded force. This causes the connecting block 24 to move leftward, while the other connecting block 24 moves rightward. This causes the pressing strip 25 to move leftward, which in turn causes the linkage block 26 to move leftward. The linkage block 26 then causes the linkage strip 27 to move leftward, while the other linkage strip 27 moves rightward.

[0036] Then, when the internal multi-point tilt synchronous support of the present invention is performed, the linkage strip 27 drives the multiple hinged strips 3 to move left, the hinged strips 3 move left along the inside of the slide frame 21, the hinged strips 3 drive the two linkage columns 4 to move left, the linkage column 4 drives one end of the sleeve strip 5 to move left, the sleeve strip 5 drives the linkage shaft 6 to move, the linkage shaft 6 drives the tilted slot column 7 to move, and the tilted slot column 7 moves along the inner wall of the sleeve slider 14. The T-shaped strip 15 is supported by the positioning outer slot frame 9, and the T-shaped strip 15 supports the sleeve slider 14. The sleeve slider 14 can ensure that the tilted slot column 7 moves stably. The tilted slot column 7 drives the tilted inner support plate 8 to move, and the two tilted inner support plates 8 inside the multiple positioning outer slot frames 9 on the right side move synchronously, and the two tilted inner support plates 8 inside the multiple positioning outer slot frames 9 on the left side also move synchronously. In this way, the multiple tilted inner support plates 8 can be synchronously moved to the internal splicing support position of the steel truss at different tilt angles to achieve multi-point tilt synchronous sliding support. Please refer to the attached document for the movement direction described in the above paragraph. Figure 7 -Attached Figure 9 The view orientation.

[0037] At the same time, when the multi-point internal linkage support of the present invention is in operation, when the hinge bar 3 moves to the left, the hinge bar 3 will drive the linkage bar 16 to move to the left, the linkage bar 16 will drive the L-shaped bar 17 to move to the left, the L-shaped bar 17 will drive the support bar 18 to move to the left, the support bar 18 will drive the support inner block 19 to move to the left synchronously, and the support inner block 19 will move synchronously along the inside of the positioning outer trough frame 9. The support inner block 19 inside the right-side positioning outer trough frame 9 will move to the left synchronously, while the support inner blocks 19 inside the multiple positioning outer trough frames 9 on the left can move to the right synchronously. Multiple support inner blocks 19 can synchronously enter the lateral support position inside the steel truss. Please refer to the attached document for the movement direction described in the previous paragraph. Figure 1 -Attached Figure 5 The view orientation.

[0038] At the same time, the L-shaped bar 17 drives the concave inclined plate 20 to move left, and the concave inclined plate 20 moves left along the inside of the positioning outer trough frame 9. In this way, the concave inclined plates 20 inside the multiple positioning outer trough frames 9 on the right can be synchronously moved to the left to enter the concave support position inside the steel truss, while the concave inclined plates 20 inside the multiple positioning outer trough frames 9 on the left can be synchronously moved to the right to enter the concave support position inside the steel truss. When the hinged bar 3 moves to the left, it will drive the sensing block 12 to move left. The distance sensor 11 can sense the distance between the distance sensor 11 and the sensing block 12. When the distance value sensed by the distance sensor 11 is the same as the distance value set by the controller 29, the reduction motor 28 is turned off by the controller 29, which can ensure that the multiple inclined inner support plates 8 and the multiple support inner blocks 19 and the multiple concave inclined plates 20 move synchronously to the designated support position. Please refer to the attached for the movement direction described in the above paragraph. Figure 4 -Attached Figure 6 The view orientation.

[0039] Finally, when the present invention is assembled and welded, after the multi-point sliding support is completed inside the steel truss, the construction personnel weld and assemble the connection positions of the workpieces supported inside the steel truss to complete the assembly operation of the steel truss.
