Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] Embodiment 1:

[0033] See also Figure 1-5 The present embodiment discloses a pile foundation self-elevating construction platform, comprising a third circular ring 5, a rubber tube 6 and a circular cover shell 1, a first circular ring 2 is fixed to the top of the cover shell 1, a rotatable second circular ring 4 is mounted on the first circular ring 2, the rubber tube 6 passes through the first circular ring 2 and the second circular ring 4, the top of the rubber tube 6 and the side of the third circular ring 5 are detachably connected, the bottom of the rubber tube 6 and the side of the cover shell 1 are detachably connected, a plurality of connecting ropes 10 are provided on the outer side of the rubber tube 6, the two ends of the connecting rope 10 are respectively fixedly connected to the first circular ring 2 and the second circular ring 4, a driving component 3 for driving the second circular ring 4 to rotate is mounted on the cover shell 1, the bottom of the inner cavity of the cover shell 1 is connected to one end of the second tube body 11, the other end of the second tube body 11 is connected to the air outlet of the external air pump, and no less than three power components 9 are mounted on the inner wall of the cover shell 1.

[0034] The cover shell 1 includes two arc-shaped plates buckled toward each other, and the two arc-shaped plates are fixed together by bolts or buckles. The first circular ring 2 includes two first arc-shaped rods, the second circular ring 4 includes two second arc-shaped rods, and the third circular ring 5 includes two third arc-shaped rods, and the two third arc-shaped rods are buckled and fixed toward each other. The rubber tube 6 is made by bending and connecting the two ends of a rubber sheet, and the two ends of the rubber sheet are connected by glue or a waterproof zipper, and a first arc-shaped rod is fixed on each arc-shaped plate.

[0035] Furthermore, the driving assembly 3 is an electric telescopic rod or a hydraulic jack commonly used in the prior art.

[0036] The working process and principle of this embodiment are:

[0037] Initially, the two arc-shaped plates are separated and the two ends of the rubber sheet are not fixed together.

[0038] The operator makes the two arc plates buckle on the pile foundation, and the operator connects the two arc plates by bolts or buckles. The pile foundation is located between the power components 9, and the rubber sheet is bent and covered on the pile foundation. The operator connects the two horizontal ends of the rubber sheet by glue bonding or waterproof zippers, and the top end of the rubber tube 6 and the side of the third ring 5 are fixed and sealed by bolts or buckles. The bottom end of the rubber tube 6 and the side of the cover shell 1 are fixed and sealed by bolts or buckles. The operator makes the driving component 3 push the second ring 4 to rotate, and the second ring 4 tightens the rubber tube 6 by the connecting rope 10, and the rubber tube 6 is attached to the pile foundation. The power component 9 enables the cover shell 1 to move along the length direction of the pile foundation.

[0039] The operator enters the cover 1, and then the external air pump injects air into the cover 1 through the second tube 11. The operator moves the cover 1 downward along the pile foundation through the power assembly 9, and the cover 1 enters the water. The rubber tube 6 tightened by the connecting rope 10 prevents water from entering from the top of the cover 1, and the rubber tube 6 does not affect the movement of the cover 1 along the pile foundation. The operator detects the pile foundation in the cover 1 to ensure the safety of the operator and reduce the impact of flowing water on the operator's detection of the pile foundation.

[0040] Furthermore, the connecting ropes 10 are elastic rubber ropes or elastic nylon ropes, so that the tightening degree of each connecting rope 10 on the rubber tube 6 is similar.

[0041] Furthermore, on any plane passing through the axis of the housing 1 , there are at least four contact points between the connecting rope 10 and the rubber tube 6 , so as to prevent a single break in the rubber tube 6 from causing air loss in the housing 1 .

[0042] Furthermore, a slot is provided on the second arc rod, and a block adapted to the slot is provided on the first arc rod. When the second ring 4 clamps the rubber tube 6 through the connecting rope 10, the slot of the second arc rod is engaged with the blocks of the two first arc rods, thereby improving the stability of the buckling of the two cover shells 1.

[0043] Embodiment 2:

[0044] like Figure 1-3 As shown, this embodiment discloses a pile foundation self-lifting construction platform, and its structure is roughly the same as that of the first embodiment, except that this embodiment also includes a first tube body 8, the interior of the third ring 5 is hollow, and a plurality of vents connected to the inner cavity of the third ring 5 are opened at equal angles on the third ring 5, and the inner cavity of the third ring 5 and the bottom of the inner cavity of the cover shell 1 are connected through the first tube body 8.

[0045] The working process and principle of this embodiment are:

[0046] After the cover shell 1 enters the water, the air in the cover shell 1 is ejected through the first tube body 8, the inner cavity of the third ring 5, and the air holes on the third ring 5. The air ejected from the air holes of the third ring 5 forms an annular bubble wall around the pile foundation. The bubble wall weakens the water flow toward the pile foundation. The bubble wall reduces the settlement of silt on the rubber tube 6, reduces the resistance of the cover shell 1 during the rising process along the pile foundation, and improves the reliability of the pile foundation self-elevating construction platform.

[0047] Embodiment three:

[0048] like Figure 5 As shown, this embodiment discloses a pile foundation self-lifting construction platform, and its structure is roughly the same as that of the second embodiment, except that the power assembly 9 of this embodiment includes a pushing assembly 93, one end of the pushing assembly 93 is connected to the inner wall of the cover 1, and the other end of the pushing assembly 93 is rotatably mounted with a mounting frame 92, and both ends of the mounting frame 92 are mounted with rotating guide wheels 91.

[0049] The two guide wheels 91 of the power assembly 9 are both against the pile foundation.

[0050] At least one guide wheel 91 is a hub motor with a tire installed, and the other guide wheels 91 are elastic wheels. The hub motor is electrically connected to an external power source.

[0051] Preferably, the pushing assembly 93 is an electric telescopic rod or a hydraulic jack.

[0052] The working process and principle of this embodiment are:

[0053] The operator adjusts the squeezing pressure of the guide wheel 91 on the pile foundation by pushing the component 93. The operator controls the forward and reverse rotation and speed of the hub motor, so that the two guide wheels 91 of the power component 9 move along the surface of the pile foundation. The two guide wheels 91 of the power component 9 adapt to the uneven surface of the pile foundation, ensuring the positioning effect of the power component 9 on the cover 1.

[0054] Furthermore, the housing 1 can be kept at a predetermined depth underwater by the friction between the rubber tube 6 and the pile foundation, and the friction between the guide wheel 91 and the pile foundation.

[0055] Embodiment 4:

[0056] like Figure 3 , 5 As shown, this embodiment discloses a pile foundation self-lifting construction platform, and its structure is substantially the same as that of the third embodiment, except that, in this embodiment, the pushing component 93 and the inner wall of the cover shell 1 are connected via a bearing 95, and a fixing frame 94 is fixed on the pushing component 93, and a threaded hole is provided on the fixing frame 94, and a positioning bolt is installed on the threaded hole.

[0057] The working process and principle of this embodiment are:

[0058] When the operator needs to stay at a predetermined depth underwater for a long time, the operator shortens the length of the propulsion assembly 93, and then the operator rotates the propulsion assembly 93 so that the line connecting the two guide wheels 91 in the power assembly 9 is perpendicular to the pile foundation, and then the operator lengthens the propulsion assembly 93. The two guide wheels 91 of the power assembly 9 rest against the pile foundation to improve the stability of the cover 1 underwater.

[0059] The operator rotates the positioning bolt so that the positioning bolt abuts against the bearing 95 or the cover 1 to prevent the push assembly 93 from rotating and ensure that the guide wheel 91 squeezes the pile foundation.

[0060] Embodiment five:

[0061] like Figure 1 , 2 As shown, this embodiment discloses a pile foundation self-elevating construction platform, and its structure is substantially the same as that of the second embodiment, except that a valve 7 is installed on the first pipe body 8 of this embodiment.

[0062] The working process and principle of this embodiment are:

[0063] The greater the underwater depth of the housing 1, the greater the opening of the valve 7, so that the density of the bubbles in the bubble wall is maintained within a set range.

[0064] The operator adjusts the density of the bubbles in the bubble wall by adjusting the opening of the valve 7, thereby adjusting the energy consumption of the pile foundation self-elevating construction platform.

[0065] Embodiment six:

[0066] like Figure 1 , 4 As shown, this embodiment discloses a pile foundation self-elevating construction platform, and its structure is roughly the same as that of the first embodiment, except that in this embodiment, a manhole is opened on one of the arc plates, and an opening and closing door panel is installed on the manhole to facilitate the operator to enter and exit the cover 1.

[0067] When water leaks from the housing 1 , the operator opens the door panel to facilitate the operator to escape from the housing 1 underwater.

[0068] Embodiment seven:

[0069] like Figure 2 As shown, this embodiment discloses a pile foundation self-lifting construction platform, and its structure is substantially the same as that of the first embodiment, except that the outer side surface of the rubber tube 6 and the second ring 4 of this embodiment are detachably sealed and connected, and the cover 1, the first ring 2, the second ring 4, and the rubber tube 6 form a closed chamber.

[0070] The working process and principle of this embodiment are:

[0071] When the rubber tube 6 and the pile foundation rub against each other and a crack occurs, the air in the cover shell 1 enters the closed chamber through the crack, and the air entering the closed chamber stays in the closed chamber, reducing the loss of air in the closed chamber and improving the safety of the pile foundation self-elevating construction platform.

[0072] Embodiment eight:

[0073] like Figure 3 , 4 As shown, this embodiment discloses a pile foundation self-elevating construction platform, and its structure is substantially the same as that of the first embodiment, except that a support frame 12 is fixed to the bottom of the inner cavity of the cover shell 1 in this embodiment, and the support frame 12 provides a support point for the operator to stand on the cover shell 1.

[0074] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
