The front baffle 31 is an anti-slip plate. The pier 100 is placed horizontally on the top surface of the bottom support block 10, and the left end face of the pier 100 is close to or against the front wall surface of the front baffle 31.

[0022] The bottom base 20 has two tilting cylinders 21 connected to the left and right sides of the front part by hinge shafts. The ends of the push rods of the two tilting cylinders 21 drive the bottom support block 10 to tilt.

[0023] The bottom support block 10 has two side vertical blocks 11 fixed on the left and right sides of the middle part. The upper part of the two side vertical blocks 11 is equipped with a horizontal push rod 12, which is located above the middle part of the pier column 100.

[0024] Furthermore, the bottoms of the two side vertical blocks 11 are fixed to the upper parts of the left and right sides of the bottom support block 10. Side locking cylinders 13 are fixed on the upper outer walls of the two side vertical blocks 11. The end of the push rod of the side locking cylinder 13 extends into the outwardly extending insertion hole 14 formed on the upper part of the inner side wall of the corresponding side vertical block 11. The end of the push rod of the side locking cylinder 13 is fixed with a horizontal push rod 12. The two horizontal push rods 12 are partially located above the top surface of the middle part of the pier column 100.

[0025] A guide sleeve 15 is fixed on the inner wall of the insertion hole 14, and the inner end of the transverse push rod 12 is located in the guide sleeve 15.

[0026] The guide sleeve 15 is a rectangular sleeve, and the transverse push rod 12 is a rectangular hollow rod that cooperates with the guide sleeve 15. The outer side wall of the transverse push rod 12 is in close contact with the inner side wall of the guide sleeve 15. The guide sleeve 15 serves to guide and protect, reducing wear and damage between the transverse rod 12 and the insertion hole 14.

[0027] Furthermore, a wear-resistant protective plate 1 is fixed on the top surface of the bottom support block 10, and the bottom surface of the pier 100 presses against the top surface of the wear-resistant protective plate 1.

[0028] One end of the first rod 2 is movably connected to the outer wall at the rear of the bottom seat 20 via a hinge shaft. One end of the second rod 3 is movably connected to the outer wall at the rear of the bottom support block 10 via a hinge shaft. The other ends of the first rod 2, the other ends of the second rod 3, and the end of the push rod of the tilting cylinder 21 are movably connected via the same hinge shaft.

[0029] The left and right sides of the top surface of the rear support block 30 are both formed with mounting grooves 32. The rear flipping limit block 33 is inserted into the corresponding mounting groove 32. The upper part of the rear flipping limit block 33 extends out of the top surface of the mounting groove 32. The lower part of the rear of the rear flipping limit block 33 is formed with a connecting part 34. A rear push cylinder 35 is provided at the rear of the mounting groove 32. The connecting shaft fixed on the middle outer wall of the rear push cylinder 35 is movably connected to the inner wall of the corresponding mounting groove 32. The end of the push rod of the rear push cylinder 35 is movably connected to the corresponding connecting part 34 through a hinge shaft.

[0030] When using this embodiment, as follows: Figures 1 to 3 As shown, the bottom support block 10 is vertical at this time. After the pier 100 is lifted vertically by a crane, it is placed on the top surface of the front baffle 31 (this surface is the front wall surface when it is placed horizontally). Then, the push rods of the two side locking cylinders 13 push the two horizontal push rods 12 to extend most of their respective guide sleeves 15 and are located on the left side of the middle of the pier 100 (on the top surface of the left and right sides of the middle of the pier 100 when it is horizontal). Then, the push rods of all the rear push cylinders 35 push the rear flipping limit block 33 to flip, so that it is located on the lower left side of the pier 100 for further limiting protection.

[0031] Then, by retracting the push rods of the two tilting cylinders 21, the bottom support block 10 is tilted to a horizontal position, at which point the pier 100 is placed horizontally, which is very convenient.

[0032] Subsequently, it is only necessary to push the push rod of the rear-push cylinder 35 to retract, so that the rear flipping limit block 33 flips and no longer blocks the bottom of the pier 100. The push rods of the two side locking cylinders 13 retract, so that the two lateral push rods 12 no longer block the pier 100.

[0033] Then, the pier column 100 is lifted horizontally by a crane and placed onto a transport vehicle, which is very convenient.

[0034] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
