[0035] As shown in the drawings, Figure 1 and Figure 4 the bottom surface of the support rod 17 is fixedly connected with a second wedge-shaped seat 22; the first wedge-shaped seat 21 and the second wedge-shaped seat 22 are matched with each other; during work, when it is needed to lower the top rod 4 again, the worker can start the hydraulic cylinder 20 to lift the second wedge-shaped seat 22, and then lift the first wedge-shaped seat 21 by the second wedge-shaped seat 22, so as to lift the support column away from the recess 19; at the same time, due to the inclined surface of the second wedge-shaped seat 22, the support rod 17 can slide along the limiting groove 18 away from the recess 19 when being lifted away from the recess 19, so as to make the top rod 4 more easily lowered, and facilitate the subsequent transportation of the prefabricated pier column.

[0036] As shown in the drawings, Figure 4 the top surface of the first wedge-shaped seat 21 is provided with a fixed groove 23; the bottom surface of the second wedge-shaped seat 22 is fixedly connected with a fixed protrusion 24 matched with the fixed groove 23; the fixed protrusion 24 can be clamped with the fixed groove 23; during work, when the first wedge-shaped seat 21 slides into the recess 19, the fixed protrusion 24 on the surface of the second wedge-shaped seat 22 is clamped into the fixed groove 23 on the surface of the first wedge-shaped seat 21, so as to complete the relative fixation of the first wedge-shaped seat 21 and the second wedge-shaped seat 22, prevent the first winch 6 from over-winding the cable, and cause the top rod 4 and the push plate 3 to be separated from the surface of the prefabricated pier column, so as to cause the prefabricated pier column to be tilted.

[0037] As shown in the drawings, Figure 1As shown in the drawings, the base 1 is fixedly connected with a mounting seat 25 at one end away from the rotating seat 5; the top surface of the mounting seat 25 is fixedly connected with a second winch 26; the base 1 is provided with a fixing module 27 at one end close to the mounting seat 25, and a cable is installed between the fixing module 27 and the second winch 26; the first winch 6 is a prior art, and the specific connection mode is not described in detail; and the specific model is selected as required; during work, when the precast pier column is lifted by the top rod 4, the worker fixes the fixing module 27 at the bottom of the precast pier column, at this time, the worker starts the second winch 26, and the precast pier column is pulled through the cable to deflect away from the top rod 4 until the precast pier column is completely vertical, at this time, the precast pier column is hoisted by using a hoisting device, which can further reduce the shaking of the precast pier column when it is just hoisted, and further reduce the safety risk during hoisting of the precast pier column.

[0038] As shown in the drawings, Figure 1 and Figure 5 As shown in the drawings, the fixing module 27 comprises a connecting plate 28, and the connecting plate 28 is fixedly connected with the cable; the connecting plate is made of flexible material; a plurality of fixing pins 29 are fixedly connected to the surface of the connecting plate 28; a plurality of strip-shaped protrusions 30 are fixedly connected to the surface of the fixing pin 29; the strip-shaped protrusions 30 are made of rigid material; during work, when it is necessary to fix the fixing module 27 to the precast pier column, the worker can first insert some wood chips into the mounting hole at the bottom of the precast pier column, then insert the pins on the surface of the connecting plate 28 into the mounting hole of the precast pier column, and further insert the pins into the mounting hole by knocking the connecting plate 28, so that the strip-shaped protrusions 30 on the surface of the pin can cooperate with the wood chips, so that the fixing between the pin and the mounting hole is more compact, and the pin is prevented from being separated from the mounting hole on the surface of the precast pier column during work, so that the precast pier column is prevented from falling.

[0039] Example two

[0040] As shown in the drawings, Figure 6 As shown in the drawings, the top surface of the mounting seat 25 is fixedly connected with a plurality of uniformly arranged oil pressure buffers 31; the piston top surface of the oil pressure buffer 31 is provided with a supporting plate 32; during work, when the precast pier column is pulled to be vertical, the bottom of the precast pier column will press the supporting plate 32, and then the supporting plate 32 will press the oil pressure buffer 31, so as to reduce the speed of the precast pier column during deflection, prevent the precast pier column from being deflected excessively due to the rapid deflection of the precast pier column, and prevent the precast pier column from being damaged.

[0041] In operation, the prefabricated pier column is generally laid horizontally in the carriage during transportation, and needs to be erected and installed vertically at the construction site, so the embodiment of the application can be installed on the carriage, when the transport vehicle carries the prefabricated pier column to the construction site, the worker starts the first winch 6, the cable is wound by the first winch 6, the top rod 4 is pulled up through the cable, the top rod 4 is rotated towards the rotating seat 5, and the push plate 3 at the top of the top rod 4 pushes the prefabricated pier column, so that the prefabricated pier column is rotated away from the rotating seat 5, when the hoisting equipment hoists the prefabricated pier column, the prefabricated pier column has been lifted, the hoisting equipment only needs to fix the top of the prefabricated pier column, and the prefabricated pier column can be hoisted vertically, so that the operation of turning over the prefabricated pier column by the hoisting equipment is avoided, the shaking of the prefabricated pier column during hoisting is reduced, and the risk of accidents during hoisting is reduced.

[0042] When the top rod 4 drives the push plate 3 to rotate, the push plate 3 slides along the surface of the prefabricated pier column, at this time, the rollers 9 in the installation groove 7 are in contact with the surface of the prefabricated pier column and rotate, so that the friction when the push plate 3 relatively displaces with the prefabricated pier column is reduced, the wear of the push plate 3 is reduced, and the service life of the push plate 3 is prolonged.

[0043] Since the surface of the prefabricated pier column generally has a groove, in order to avoid the prefabricated pier column from deviating when the push plate 3 pushes the prefabricated pier column, the roller 9 can be clamped in the groove on the surface of the prefabricated pier column, so the worker can first rotate the threaded rod 12 at the bottom of the connecting seat 11, so that the threaded rod 12 drives the connecting seat 11 and the rotating shaft 8 to move along the sliding groove 10 towards the connecting rod 13, at this time, the rollers 9 on the surface of the rotating shaft 8 are not in contact with the surface of the prefabricated pier column, then the roller 9 is slid to make the position of the roller 9 correspond to the groove on the surface of the prefabricated pier column, and then the worker rotates the threaded rod 12 to lift the rotating shaft 8 by the threaded rod 12, so that the roller 9 is clamped in the groove on the surface of the prefabricated pier column, thereby reducing the risk of deviation of the prefabricated pier column when the push plate 3 pushes the prefabricated pier column.

[0044] When the roller 9 is worn, the worker can pry open the clamping groove 15 of the rotating drum 14, so that the opening of the clamping groove 15 is enlarged, so that the worker can take down the rotating drum 14 from the surface of the rotating shaft 8, and then the worker can replace the worn polyurethane pad 16 on the surface of the rotating drum 14, thereby prolonging the service life of the roller 9.

[0045] When the top rod 4 rotates, the support rod 17 on the surface of the top rod 4 rotates away from the top rod 4, and the end of the support rod 17 away from the top rod 4 slides along the limiting groove 18 until the support rod 17 is clamped in the recess 19, at this time, the support rod 17 can support the top rod 4 to improve the stability of the top rod 4 supporting the prefabricated pier column.

[0046] When it is necessary to lower the jacking rod 4 again, the worker can start the hydraulic cylinder 20 to lift the second wedge-shaped seat 22, and then lift the first wedge-shaped seat 21 by the second wedge-shaped seat 22, so as to lift the supporting column away from the groove 19, and at the same time, due to the inclined surface of the second wedge-shaped seat 22, the supporting rod 17 can slide along the limiting groove 18 to the direction away from the groove 19 when being lifted away from the groove 19, so that the jacking rod 4 is more easily lowered, and the prefabricated pier column is conveniently transported again.

[0047] When the first wedge-shaped seat 21 slides into the groove 19, the fixed protrusion 24 on the surface of the second wedge-shaped seat 22 is clamped into the fixed groove 23 on the surface of the first wedge-shaped seat 21, so as to complete the relative fixation of the first wedge-shaped seat 21 and the second wedge-shaped seat 22, and prevent the first winch 6 from over-winding the cable, so as to cause the jacking rod 4 to be separated from the surface of the prefabricated pier column, and thus cause the prefabricated pier column to be tilted.

[0048] When the jacking rod 4 lifts the prefabricated pier column, the worker fixes the fixing module 27 at the bottom of the prefabricated pier column, and then starts the second winch 26 to pull the prefabricated pier column by the cable to deflect the prefabricated pier column to the direction away from the jacking rod 4 until the prefabricated pier column is completely vertical, and then uses the hoisting equipment to hoist the prefabricated pier column, so as to further reduce the shaking of the prefabricated pier column when being hoisted, and further reduce the safety risk when hoisting the prefabricated pier column.

[0049] When it is necessary to fix the fixing module 27 to the prefabricated pier column, the worker can first insert some wood chips into the mounting hole at the bottom of the prefabricated pier column, and then insert the latch on the surface of the connecting plate 28 into the mounting hole of the prefabricated pier column, and further insert the latch into the mounting hole by knocking the connecting plate 28, so that the latch and the mounting hole are fixed more tightly, and the latch is prevented from being separated from the mounting hole on the surface of the prefabricated pier column during work, so as to cause the prefabricated pier column to be tilted.

[0050] When the prefabricated pier column is pulled to be vertical, the bottom of the prefabricated pier column is pressed against the supporting plate 32, and then the supporting plate 32 is pressed against the oil buffer 31, so as to reduce the speed of the prefabricated pier column during deflection, and prevent the prefabricated pier column from being tilted excessively due to the rapid deflection of the prefabricated pier column, and thus prevent the prefabricated pier column from being damaged.
