The first support column 1 has a first helicoid 101 at the bottom and a second helicoid 301 at the top of the second support column 3. The first helicoid 101 is congruent with the second helicoid 301, and the first helicoid 101 is in contact with the second helicoid 301. Specifically, the second spiral surface 301 is a curved surface formed by the constant-speed rotation and the constant-speed axial movement of the first bus bar around the axis of the second support column 3, and the angle of the rotation of the first bus bar around the axis of the second support column 3 is 360 °. The first generatrix is a straight line and is perpendicular to the axis of the second support column 3.
A circle of first annular groove is sunken in the outer wall of the second supporting column 3, and a first annular sheet 4 is rotatably arranged in the first annular groove.
The top end surface of the first ring plate 4 extends upwards to form a first sleeve 401. A plurality of guide grooves 402 are recessed in the inner wall of the first sleeve 401, and the length direction of the guide grooves 402 is parallel to the axial direction of the first sleeve 401. A plurality of guide protrusions 102 are protruded on the outer wall of the first support column 1, and the length direction of the guide protrusions 102 is parallel to the axial direction of the first support column 1. The guide protrusions 102 correspond to the guide grooves 402 one by one, and the guide protrusions 102 are slidably fitted in the corresponding guide grooves 402.
It should be noted that the first support column 1, the second support column 3, the first ring piece 4 and the first sleeve 401 are all coaxial.
In this embodiment, by rotating the first sleeve 401, the first support column 1 is driven to rotate by the cooperation of the guide protrusion 102 and the guide groove 402, and simultaneously, the first support column 1 can move up and down by the cooperation of the first spiral surface 101 and the second spiral surface 301. After the first supporting column 1 is adjusted to the height to be adjusted, the first ring piece 4 and the second supporting column 3 are welded and fixed, so that the relative rotation of the first sleeve 401 relative to the second supporting column 3 is limited, and at this time, the first supporting column 1 cannot rotate around the axis of the first supporting column 1 because the guide protrusion 102 is located in the guide groove 402, so that the first supporting column 1 cannot move downwards.
Compared with the height-adjustable floor support in the prior art, the height-adjustable high bearing capacity support in the embodiment avoids directly bearing the load in the vertical direction through the threads, and the first spiral surface 101 and the second spiral surface 301 are contacted to bear the load in the vertical direction, so that the contact area is increased, the bearing capacity of the support is improved, and the support is prevented from losing efficacy due to thread damage.
According to a further embodiment, the top of the second support column 3 has two second helicoids 301, the first generatrix being rotated by an angle of 180 ° around the axis of the second support column 3.

The bottom end face of the first portion 304, the outer wall of the first cylinder 3051, and the top end face of the second portion 305 collectively form a first annular groove.
The second helicoid 301 is located on top of the first portion 304 and the corrugated strip 303 is located on the outer wall of the second portion 305.
In this embodiment, the first portion 304 and the second portion 305 are detachably connected by a screw, and during assembly, the first ring piece 4 is firstly sleeved on the first cylinder 3051, and then the second stud 3052 is screwed into the first blind hole 3041, so as to facilitate installation of the first ring piece 4.
According to a further embodiment, the base 5 has a bearing part 501 which is arched. The arch can disperse pressure downwards and outwards, so that the arch can bear heavier force, and the height-adjustable high-bearing-capacity support can bear larger load.
A third stud 5011 protrudes from the top of the load bearing part 501. The bottom surface of the second portion 305 is provided with a second blind hole 3053, the second blind hole 3053 is provided with internal threads, and the third stud 5011 is in threaded fit with the internal threads of the second blind hole 3053. It should be noted that the top of the load-bearing part 501 abuts against the bottom surface of the second part 305 to bear the vertical load from the top support 2, and the third stud 5011 and the internal thread of the second blind hole 3053 play a role of fixed connection, and do not bear the vertical load from the top support 2.
A flange 502 extends from the bottom edge of the bearing portion 501, and a first through hole 5021 is formed in the flange 502. When installing such a height-adjustable high load-bearing bracket, a screw is passed through the first through hole 5021 to fixedly connect the flange 502 with the ground.
The third stud 5011 is sleeved with an annular gasket 6, and the annular gasket 6 is located between the base 5 and the second portion 305. When the floor needs to be raised higher than the height that the first support rod can be adjusted, the annular gasket 6 is sleeved on the third stud 5011 to adjust the height.
According to a further embodiment, the bottom surface of the top support 2 is extended by a ring of first fixing rings 201.
The top end surface of the first support column 1 is recessed with a circle of second annular groove 103 matched with the first fixing ring 201, and the first fixing ring 201 extends into the second annular groove 103.
