The schematic implementation mode of the present utility model and its description are only used to explain the present utility model and shall not be used as a limitation to the present utility model.
[0026] Embodiment
[0027] Please refer to Figures 1 to 4 .
[0028] This embodiment provides a support device for the inner circle of a steel reinforcement cage, including a central axis 1, a support member 2, a height adjustment component 3 and a drive component 4; the central axis 1 is arranged parallel to the support member 2, and the height adjustment component 3 is installed between the central axis 1 and the support member 2; the height adjustment component 3 is used to adjust the distance between the central axis 1 and the support member 2, and the drive component 4 is used to drive the height adjustment component 3.
[0029] In the above embodiments, the steel cage is often used at the construction site. The steel cage plays a role in restraining the pile body concrete, enabling it to withstand a certain axial tension. When fabricating the steel cage, strict control over the quality of the steel bars is required. The steel bars must be stored in batches according to different steel types, grades, brands, and specifications without being mixed. During storage, the steel bars should be protected from rust and contamination. When the steel bars are stacked outdoors, they should be elevated and covered. Before processing, the surface of the steel bars must be clean, free of oil stains, paint stains, cement slurry, and rust, etc. When fabricating the steel cage, first, the inner ring is tightened and fixed to prevent the inner ring from tilting or shifting during welding, thereby improving the quality of the finished steel cage. After multiple inner rings are fixed, the main steel bars are arranged along the directions of the multiple inner rings, and then the main steel bars are welded to the multiple inner rings by electric welding. After the main steel bars and the inner rings are welded, the spiral reinforcement is wound around the multiple main steel bars, and then the spiral reinforcement is welded to the multiple main steel bars by electric welding. Specifically, the length of the central shaft 1 is set according to the size of the fabricated steel cage. The support member 2 is parallel to the central shaft 1, and the shape of the support member 2 can be a cuboid. The middle part of the support member 2 is hollowed out. A height adjustment assembly 3 is installed between the bottom of the support member 2 and the central shaft 1. The driving assembly 4 is installed on the central shaft 1. The construction workers can control the height adjustment assembly 3 through the driving assembly 4, and the height adjustment assembly 3 can drive the support member 2 to approach or move away from the central shaft 1. When the construction workers fix the inner ring, they first control the support member 2 to approach the central shaft 1 (reducing the distance between the central shaft 1 and the support member 2), then the inner ring is sleeved on the central shaft 1 and the support member 2, and finally, the support member 2 is controlled to move away from the central shaft 1 (increasing the distance between the central shaft 1 and the support member 2). At this time, one side of the inner ring is fixed by the central shaft 1, and the other side of the inner ring is fixed by the support member 2. The inner ring is in a tensioned and fixed state. In this state, the construction workers can weld the main steel bars to the fixed inner ring, and the welding points are located at the hollowed-out part of the support member 2 to avoid damaging the support member 2 during welding. Further, a plurality of support members 2 can be arranged along the circumferential direction of the central shaft 1. Each support member 2 is connected to the central shaft 1 through an independent height adjustment assembly 3. The plurality of support members 2 can all move away from or approach the central shaft 1. When fixing the inner ring, the plurality of support members 2 can act on the inner side wall of the inner ring simultaneously, improving the stability of the inner ring.
[0030] In this embodiment, during the process of fabricating the steel cage, the inner ring can be fixed by "expanding" the support member 2. The fixed inner ring will no longer tilt or shift. When the construction workers weld the main steel bars to the inner ring, it is more accurate, improving the quality of the finished steel cage. Since the position of the inner ring will no longer change, the construction workers do not need to correct the position of the inner ring during welding, resulting in higher overall efficiency and a higher degree of automation.
[0031] Furthermore, in the present utility model, the height adjustment assembly 3 includes a bearing base, a first adjustment member 6, and a second adjustment member 7; the bearing base is mounted on the central shaft 1, one end of the first adjustment member 6 is rotatably connected to the bearing base, and the other end of the first adjustment member 6 is rotatably connected to the support member 2; one end of the second adjustment member 7 is rotatably connected between the two ends of the first adjustment member 6, and the drive assembly 4 controls the other end of the second adjustment member 7 to move axially along the central shaft 1, thereby adjusting the height of the first adjustment member 6.
[0032] In this embodiment, the height adjustment assembly 3 is composed of a bearing base, a first adjustment member 6, and a second adjustment member 7. The bearing base is mounted on the side wall of the central shaft 1. The first adjustment member 6 can be composed of two arc-shaped plates 8 and a connecting member 9. The two arc-shaped plates 8 are connected by the connecting member 9. One end of the arc-shaped plate 8 is rotatably connected to the bearing base, and the other end of the arc-shaped plate 8 is rotatably connected to the support member 2; the second adjustment member 7 is rotatably connected to the outer side walls of the two arc-shaped plates 8. The end of the second adjustment member 7 away from the arc-shaped plate 8 is controlled by the drive assembly 4, so that the end of the second adjustment member 7 away from the arc-shaped plate 8 can move along a straight line parallel to the central shaft 1. When moving closer to the rotation point of the arc-shaped plate 8 and the bearing base, the support member 2 rises, and when moving away from the rotation point of the arc-shaped plate 8 and the bearing base, the support member 2 drops; during the rising and dropping process of the support member 2, not only can the position of the inner ring be adjusted, but it can also be applicable to inner rings with different inner diameters.
[0033] Furthermore, in the present utility model, one end of the first adjustment member 6 is hinged to the bearing base, and the other end of the first adjustment member 6 is hinged to the support member 2.
[0034] In this embodiment, the first adjustment member 6 can be composed of two arc-shaped plates 8 and a connecting member 9. One end of the arc-shaped plate 8 is hinged to the bearing base, and the other end of the arc-shaped plate 8 is hinged to the support member 2. Thus, the second adjustment member 7 can push the arc-shaped plate 8 to rotate around the hinge point, and the height of the support member 2 can be adjusted during the rotation process.
[0035] Furthermore, in the present utility model, one end of the second adjustment member 7 is hinged between the two ends of the first adjustment member 6.
[0036] In this embodiment, the other end of the second adjustment member 7 makes a straight-line movement parallel to the central shaft 1 through the drive assembly 4. Since one end of the second adjustment member 7 is hinged to the arc-shaped plate 8, when the other end of the second adjustment member 7 makes a parallel movement, the arc-shaped plate 8 can be controlled to rotate to adjust the height of the support member 2.
[0037] Further, in the present utility model, the driving assembly 4 includes a driving motor 5, a lead screw 10, and a moving member 11; the driving motor 5 is installed on the central shaft 1, the output end of the driving motor 5 is connected to the lead screw 10, the lead screw 10 is arranged parallel to the central shaft 1, the lead screw 10 passes through the moving member 11, the lead screw 10 is in threaded cooperation with the moving member 11, and one end of the second adjusting member 7 away from the first adjusting member 6 is rotatably connected to the moving member 11.
[0038] In this embodiment, the driving motor 5 is installed on the side wall of the central shaft 1, the lead screw 10 is parallel to the central shaft 1 and connected to the driving motor 5, the lead screw 10 passes through between the two arc-shaped plates 8 (the first adjusting member 6), the moving member 11 is sleeved on the lead screw 10 and in threaded cooperation with the lead screw 10, and the second adjusting member 7 can be hinged to the moving member 11; after the driving motor 5 is started, it can drive the lead screw 10 to rotate forward or backward, so as to control the reciprocating movement of the moving member 11 on the lead screw. When the moving member 11 moves close to the rotation point of the arc-shaped plate 8 and the bearing base, the support member 2 rises; when the moving member 11 moves away from the rotation point of the arc-shaped plate 8 and the bearing base, the support member 2 descends.
[0039] Further, in the present utility model, a slider 12 is installed at the bottom of the moving member 11, and a slideway 13 cooperating with the slider 12 is installed on the surface of the bearing base, and the slideway 13 is arranged along the axial direction of the central shaft 1.
[0040] In this embodiment, one end of the lead screw 10 is connected to the driving motor 5, and the other end of the lead screw 10 is suspended. During the long-term operation of the lead screw 10, it will tilt, affecting the subsequent product quality; the slider 12 at the bottom of the moving member 11 can be clamped in the slideway 13 of the bearing base, and the slider 12 can slide along the direction of the slideway 13; on the one hand, the slider 12 clamped in the slideway 13 of the bearing base can support the lead screw 10 to avoid the problem of the lead screw 10 tilting after long-term operation; on the other hand, when the lead screw 10 rotates, the moving member 11 reciprocates on the lead screw 10, and the moving path of the moving member 11 is affected by the slideway 13, so that the moving member 11 always moves along the preset direction, avoiding the problem of affecting the adjustment accuracy of the support member 2.
[0041] Further, in the present utility model, a plurality of height adjustment assemblies 3 are installed between the central shaft 1 and the support member 2, and the plurality of height adjustment assemblies 3 are arranged at equal intervals.
[0042] In this embodiment, multiple height adjustment components 3 can act on the same support member 2 simultaneously. The multiple height adjustment components 3 synchronously control the support member 2 to rise or fall. The multiple height adjustment components 3 can avoid the problem of the support member 2 tilting. When adjusting the position of the inner ring, the multiple height adjustment components 3 can be controlled to lower. When the inner ring moves to the preset position, the multiple height adjustment components 3 are then controlled to rise. If the number of height adjustment components 3 is small enough, the position of the support member 2 close to the height adjustment component 3 is greatly affected by the adjustment, and the position of the support member 2 far from the height adjustment component 3 is less affected by the adjustment, resulting in the problem of the support member 2 tilting. Installing multiple height adjustment components 3 on the support member 2 solves the above problem.
[0043] Further, in the present utility model, a plurality of support members 2 are arranged circumferentially along the central axis 1. A height adjustment component 3 is installed between any one of the support members 2 and the central axis 1, and any one of the height adjustment components 3 is connected to a drive component 4.
[0044] In this embodiment, the multiple support members 2 surround the central axis 1. The corresponding drive component 4 can control the corresponding height adjustment component 3 to synchronously raise or lower the multiple support members 2. The multiple support members 2 act on the inner side wall of the inner ring simultaneously, which can increase the contact area. It can not only make the inner ring fixed more firmly, but also when the multiple support members 2 act on the same inner ring simultaneously, it can avoid the inner ring being damaged due to single-sided force deformation.
[0045] Further, in the present utility model, a synchronous controller is further included, and the multiple drive components 4 are all connected to the synchronous controller.
[0046] In this embodiment, the synchronous controller can control the multiple drive components 4 to do work at the same frequency, so that the frequencies of the multiple height adjustment components 3 are the same, and the moving states of the support members 2 are the same, improving the fixing effect on the inner ring.
[0047] Further, in the present utility model, the support member 2 is arc-shaped.
[0048] In this embodiment, the support member 2 with an arc surface can increase the contact area with the inner ring. Thus, when the support member 2 tensions the inner ring, it can avoid the inner ring being deformed and damaged.
[0049] In summary, the embodiment of the present utility model provides a support device for the inner ring of a steel reinforcement cage. During the process of manufacturing the steel reinforcement cage, the inner ring can be fixed by "expanding" the support member 2. The fixed inner ring will no longer tilt or shift. When construction workers weld the main reinforcement bars to the inner ring, it is more accurate, improving the quality of the finished steel reinforcement cage. Since the position of the inner ring will no longer change, construction workers do not need to correct the position of the inner ring during welding, and the overall efficiency is relatively high, and the degree of automation is relatively high.
