Detailed Description
The following description is of the preferred embodiments of the utility model and is not intended to limit the scope of the utility model.
As shown in fig. 1-8, a high-stability adjustable top support structurally comprises a mounting hole plate unit 1, a supporting cylinder unit 2 screwed on the mounting hole plate unit 1, a jack-up frame unit 3 inserted and arranged on the supporting cylinder unit 2, a clamping pipe unit 4 arranged on the mounting hole plate unit 1 and positioned in the supporting cylinder unit 2, and a radial inserting column unit 5 inserted and arranged on the supporting cylinder unit 2 and used for being inserted into the clamping pipe unit 4 and driving the supporting cylinder unit 2 to rotate.
In this embodiment, the width between the formwork a and the back rib b is fixed, so that the support needs to be rotationally adjusted to a corresponding length and then is kept still, and after the wall d is cured and formed, when the support needs to be removed, one end of the orifice plate mounting unit 1 is hinged and fixed, so that the support needs to be reduced in length, so as to ensure that the lifting frame unit 3 can be rotated away from the back rib b, and finally the formwork a can be integrally removed together with the support.
The clamping pipe unit 4 is fixed with the mounting hole plate unit 1, and the radial plug-in column unit 5 can be inserted into the clamping pipe unit 4 at a proper position, so that the top support can not rotate any more. In other words, as soon as the radial plug-in post unit 5 is pulled out, the jack can be pulled out again and lengthened or shortened.
The further core is therefore how the radial plug-in pin unit 5 can be pulled out relatively simply without spontaneously releasing it from the snap-in tube unit 4.
The mounting hole plate unit 1 comprises a hole plate 101 for connecting with the template a, and a screw 102 arranged on the hole plate 101 and used for being screwed with the supporting cylinder unit 2 and mounting the clamping tube unit 4.
In this embodiment, the orifice plate 101 is hinged to the template a.
The supporting cylinder unit 2 comprises a straight cylinder 201, a screw hole plate 202 which is arranged at one end position of the straight cylinder 201 and used for installing the screw 102, a jack plate 203 which is arranged at the other end position of the straight cylinder 201 and used for being inserted into the jack plate 3 of the jack-up frame unit, and a cylinder wall opening 204 which is arranged on the straight cylinder 201 and used for installing the radial inserting column unit 5.
In this embodiment, the straight barrel 201 is a cylinder or square barrel, and the latter is preferable because the wrench can directly lock the straight barrel 201 for rotation when the straight barrel 201 needs rotation adjustment.
In addition, the screw hole plate 202 is provided with a round screw hole, the socket plate 203 is provided with a common round hole, and the shape of the cylindrical wall opening 204 is also round.
The jack-up frame unit 3 includes a straight bar 301 disposed on the jack-up plate 203, and a U-shaped plate 302 disposed on an exposed end of the straight bar 301 and used for jack-up the back rib b.
In this embodiment, sliding friction needs to occur between the socket plate 203 and the U-shaped plate 302, so a ring may be further disposed on the straight rod 301 to rub the socket plate 203, and only the ring needs to be replaced in the later stage, so that the use cost may be greatly reduced, as shown in fig. 8.
The clamping tube unit 4 comprises a straight tube 401 arranged on the inner end of the screw 102 cylinder, and an axial rectangular opening 403 which is arranged on the straight tube 401 in a circle center symmetry mode and is used for radially inserting and annularly clamping the radial plug-in column unit 5.
In this embodiment, the length direction of the axial rectangular openings 403, that is, the axial direction of the straight tube 401, and the total number of the axial rectangular openings 403 is 4, that is, 8, so that 8 fixed "gears" can be selected when the straight tube 201 is adjusted for one rotation.
The radial plug-in column unit 5 comprises a radial column 501 which is plugged into the cylindrical wall opening 204 and is inserted into the axial rectangular opening 403.
In this embodiment, the straight tube 401 and the radial cylinder 501 are made of high-strength steel, and the inner head of the radial cylinder 501 clamps the axial rectangular opening 403 and the outer head clamps the cylinder wall opening 204, so that it is ensured that the straight tube 201 cannot spontaneously and accidentally rotate.
The radial plug-in column unit 5 further comprises a fixed cylinder 502 disposed on the inner side of the straight cylinder 201 and used for being inserted into the radial cylinder 501 after the radial cylinder 501 passes through the axial rectangular opening 403, and an elastic column 503 disposed on the radially outer side of the radial cylinder 501 and used for clamping and loosening prevention on the cylinder wall opening 204.
In this embodiment, if the radial cylinder 501 is used alone, it is easy to slide from the cylindrical wall opening 204, so that the elastic column 503 made of rubber material is provided and is in interference fit with the cylindrical wall opening 204, so as to ensure that the radial cylinder 501 is not easy to loose and drop.
However, there is a new problem in that the elastic posts 503 must be inserted into the cylindrical wall openings 204, and the radial posts 501 can only be partially inserted into the cylindrical wall openings 204 at most, which is far from sufficient.
Therefore, the fixing cylinder 502 is newly provided, so that the radially outer end of the radial cylinder 501 is only responsible for "anti-loosening" and the radially inner end is only responsible for locking and fixing. In other words, the cylindrical wall opening 204 and the fixed cylinder 502 are disposed in a central symmetrical positional relationship with respect to the center of the straight cylinder 201.
The radial plug-in column unit 5 further comprises an amplifying ring 504 disposed on the radial column 501 and used for blocking and preventing falling inside the cylindrical wall opening 204, wherein the external diameter of the amplifying ring 504 is equal to the width of the axial rectangular opening 403.
In this embodiment, during the rotation adjustment of the straight tube 201, the radial cylinder 501 needs to be completely separated from the straight tube 401, and at this time, the radial cylinder 501 may fall entirely from the cylindrical wall opening 204, so the radial cylinder 501 needs to be limited and prevented from falling inside the cylindrical wall opening 204, and the amplifying ring 504 is provided.
But with the new problem that if the width of the axial rectangular port 403 is equal to the diameter of the radial cylinder 501, the enlarged ring 504 cannot pass through the axial rectangular port 403 at all, and thus the outer diameter of the enlarged ring 504 is set equal to the width of the axial rectangular port 403.
Finally, this method still has a disadvantage in that two axial rectangular openings 403 are paired, one of which can firmly lock the amplifying ring 504, but the other can only pass through the radial cylinder 501 or the elastic cylinder 503 having a too small diameter, where the size cannot be locked.
The radial plug unit 5 further includes a rotation pulling block 505 provided on an exposed end of the elastic column 503.
In this embodiment, the radial cylinder 501 also has a function that the rigid radial cylinder 501 is an impetus to allow the straight cylinder 201 to rotate easily after the radial plug-in post unit 5 is completely pulled out. The rotary pulling-out block 505 is a "handle" for pulling out the radial plug-in column unit 5.
The supporting cylinder unit 2 further comprises a screw extension pipe 205 arranged on the outer side surface of the screw plate 202 and used for connecting the screw 102, and a direct jacking pipe 206 arranged on the outer side surface of the socket plate 203 and used for sleeving the straight rod 301, wherein the outer side surfaces of the screw extension pipe 205 and the direct jacking pipe 206 are both regular hexagons.
In this embodiment, the shape of the outer side surface of the regular hexagon of the screw-connected extension tube 205 and the direct jacking tube 206 is the key for driving the wrench, so as to ensure that the rotation mode of the straight tube 201 is more diversified and simplified.
The embodiments of the present utility model have been described in detail with reference to the drawings, but the present utility model is not limited to the above embodiments, and various modifications may be made within the knowledge of those skilled in the art without departing from the spirit of the present utility model. These are all non-inventive modifications which are intended to be protected by the patent laws within the scope of the appended claims.
