As shown in fig. 2, the support chassis 1 includes a support bar 11, a tripod 12, a pan-tilt 13 and a second base 14.
The support bar 11 extends in the up-down direction and is a support backbone of the entire stent. In this embodiment, the support rod 11 is made of aluminum alloy square steel.
Tripod 12 is supported on the ground, tripod head 13 is arranged on tripod 12, second base 14 is connected with tripod head 13 through bolts, and support rod 11 is arranged on second base 14. In this embodiment, the second base 14 is sleeved on the lower portion of the supporting rod 11 and glued with the supporting rod 11.
The second base 14 is provided with a plurality of ribs 14a to enhance the supporting rigidity of the support bar 11.
One end of the rotating arm 2 is sleeved on the support rod 11 and can be rotationally arranged relative to the support rod 11, so that the circumferential position of the adjustable rotating arm 2 can be rotated around the support rod 11 through the rotating arm 2, and the adjustment of the circumferential angle of the array can be realized.
The height of the rotating arm 2 above the support bar 11 can be adjusted so that adjustment of the axial height of the array can be achieved.
Specifically, as shown in fig. 1 and fig. 3, the bracket further includes a position adjuster 4, the position adjuster 4 is sleeved on the support rod 11 and can be slidably disposed along a length extending direction of the support rod 11, and one end of the rotating arm 2 is sleeved on the position adjuster 4 and can be rotatably disposed relative to the position adjuster 4.
According to the test requirement, one or more position regulators 4 are slidably arranged on the supporting rod 11, one or more rotating arms 2 are rotatably arranged on each position regulator 4, and when a plurality of rotating arms 2 are arranged, the plurality of rotating arms 2 are stacked up and down in a layered manner along the length extension direction of the supporting rod 11 at the connecting part of the rotating arms 2 and the position regulators 4.
Specifically, as shown in fig. 1, 3 and 4, the position adjuster 4 includes a first base 41 and an adjusting knob 42, the first base 41 is sleeved on the support rod 11 and is slidably disposed along the length extending direction of the support rod 11, and the adjusting knob 42 is rotatably disposed on the first base 41. In this embodiment, the adjusting knob 42 is connected to the first base 41 by a screw.
As shown in fig. 3 to 5, the first base 41 is provided with a plurality of first mounting holes 41a, the rotating arm 2 is provided with a ring groove 2a matched with the first mounting holes 41a, the plurality of first mounting holes 41a are uniformly arranged along a circumferential direction of rotation of the rotating arm 2 at intervals, the ring groove 2a extends along the circumferential direction of rotation of the rotating arm 2, and the first connecting member 5 penetrates through the ring groove 2a and the first mounting holes 41a to connect the rotating arm 2 and the position regulator 4. In this embodiment, the first connecting member 5 is a bolt. When the bolts are loosened, the rotating arm 2 can be rotated relative to the first base 41, thereby adjusting the circumferential angle of the rotating arm 2.
Because the first mounting hole 41a of part can be sheltered in rotatory in-process to the swinging boom 2, lead to part first mounting hole 41a to be unusable, set up annular 2a on the swinging boom 2, make things convenient for the swinging boom 2 to rotate and first connecting piece 5 to alternate. When rotating, the ring groove 2a can slide relative to the first connecting piece 5, thereby realizing the full coverage of the array circumferential adjusting angle. Since the number of available bolts is an important mounting index when fixing the position adjuster 4 and the rotary arm 2, the relationship between the minimum number of available first mounting holes 41a and the number of stacked layers of the rotary arm 2 will be discussed below, and the rotary arm 2 and the position adjuster 4 are first fitted to each other, and the minimum number of first mounting holes 41a is calculated by checking the overlapping ratio of the ring grooves 2a of the rotary arm 2. Then, the relationship between the number of the first mounting holes 41a, which is the smallest during rotation, and the number of layers of the rotary arm 2 is analyzed in many cases. In this embodiment, sixteen first mounting holes 41a are provided, four ring grooves 2a are provided, and the four ring grooves 2a are uniformly arranged at intervals along the circumferential direction of the rotation arm 2. When the rotating arm 2 has only one layer, the number of the first mounting holes 41a that is least available is 12, that is, 75% of the first mounting holes 41a are available; when the number of stacked layers of the rotating arm 2 is two, the minimum number of available first mounting holes 41a is 8, that is, 50% of the first mounting holes 41a are available; when the number of stacked layers of the rotating arm 2 is three, the minimum available number of the first mounting holes 41a is 4, that is, 25% is available. It follows that the more the number of stacked layers of the rotating arm 2, the less the available first mounting holes 41a, and the first mounting holes 41a are reduced to 0 as the number of layers of the rotating arm 2 increases. From this analysis, the rotating arm 2 of the present invention can achieve the best utilization rate when the number of stacked layers is three. A position regulator 4 of the present invention can accommodate one to three layers of rotating arms 2.
When the adjusting knob 42 rotates relative to the first base 41 in the first direction, the adjusting knob 42 can be pressed against the supporting rod 11, so that the relative position between the first base 41 and the supporting rod 11 is fixed, that is, the position of the position adjuster 4 on the supporting rod 11 is fixed, and the axial height of each rotating arm 2 is fixed. When the adjusting knob 42 rotates relative to the first base 41 in the second direction, the fixing between the first base 41 and the supporting rod 11 can be released, that is, the position adjuster 4 can slide up and down on the supporting rod 11 to adjust the height, that is, the axial height of each rotating arm 2. The first direction is opposite to the second direction.
