[0033] The technical solution of the present utility model will be further described below in conjunction with specific embodiments:

[0034] An adjustable pier for shipbuilding, as Figure 1 shown, includes a top cover 1, a lifting rod 2, a chassis 4, and a base 5; the top cover 1 and the upper end of the lifting rod 2 are movably connected through a sphere; the chassis 4 is installed at the upper end of the base 5, the chassis 4 is provided with a cylinder with an internal thread corresponding to the lifting rod 2 and in threaded cooperation with the lifting rod 2, the lifting rod 2 is provided with an external thread corresponding to the cylinder, the base 5 is provided with an adjusting cylinder for the lifting and accommodation of the lifting rod 2 corresponding to the cylinder, and the cylinder and the adjusting cylinder are communicated up and down; a wrench rod 3 for rotating the lifting rod 2 relative to the chassis 4 is provided at a position of the lifting rod 2 close to the top cover 1.

[0035] Specifically, as Figure 2 and Figure 3As shown in the figure, the top cover 1 includes a top plate 101 and a spherical top cover 102 provided on the lower end surface of the top plate 101. The spherical top cover 102 forms a spherical groove with a lower end opening below the top plate 101. A ball head structure 204 is provided at the upper end of the lifting rod 2 and is fitted into the spherical groove. A flange seal cover 104 for restricting the ball head structure 204 from disengaging from the spherical groove is installed at the opening position of the spherical groove of the spherical top cover 102. For the convenience of installation, the flange seal cover 104 is welded in a split structure. In this embodiment, the flange seal cover is composed of two relatively arranged parts, and the two parts are joined together to form an annular flange seal cover 102 to realize the limit of the ball head structure 204. During installation, first insert the ball head structure 204 into the spherical groove, and then install the split flange seal cover.

[0036] Preferably, a reinforcing gusset plate 103 is also installed between the spherical top cover and the top plate.

[0037] As Figure 4 As shown in the figure, the lifting rod 2 includes an adjusting rod 201 and a ball head structure 204. External threads are provided on the outside of the adjusting rod 201. The ball head structure 204 is provided at one end of the adjusting rod 201, and a baffle 202 for preventing the adjusting rod 201 from completely disengaging from the cylinder body is provided at the other end of the adjusting rod 201. The baffle 202 is detachably connected to the end of the adjusting rod 201. In this embodiment, the baffle 202 is fixed to the end of the adjusting rod 201 by bolts 203.

[0038] A through hole perpendicular to the axial direction of the adjusting rod 201 and passing through the adjusting rod 201 is provided at a position of the adjusting rod 201 close to the upper ball head structure 204 for installing the wrench rod 3; external threads are provided on the outside of the adjusting rod between the through hole and the baffle 202. In order to expose the external threads on the outside of the adjusting rod, a dust cover 7 is also provided on the upper end surface of the cylinder body of the chassis 4. The dust cover 7 is sleeved on the outside of the lifting rod 2, specifically on the outside of the adjusting rod 201.

[0039] In order to ensure that the lifting rod can provide a protective effect during both lifting and lowering, the dust cover 7 is provided with a plurality of corrugated joints for the telescopic deformation of the dust cover along the length direction of the lifting rod. One end of the dust cover 7 is connected to the upper end surface of the cylinder body, and the other end of the dust cover 7 is connected to the position of the upper end of the external threads of the lifting rod 2. The dust cover 7 is rotatably connected to the position of the upper end of the external threads. When the lifting rod 2 rises relative to the chassis 4, it drives the dust cover 7 to elongate, and when the lifting rod 2 descends relative to the chassis 4, it compresses the dust cover.

[0040] More specifically, in order to achieve a rotational connection between the dust cover 7 and the upper end of the external thread of the lifting rod 2, a circular groove 205 is provided at the upper end of the external thread of the adjusting rod 201. The upper end of the dust cover 7 is sleeved in the circular groove 205, ensuring that when the lifting rod is lifted and adjusted, it is not affected by the dust cover and the dust cover can be stretched or compressed. That is, the circular groove 205 plays a role in fixing the upper end position of the dust cover 7 but also ensures that the lifting rod can rotate relative to the dust cover. The material of the dust cover is such as thermoplastic rubber (TPR).

[0041] As Figure 5 shown, the wrench rod 3 includes a rod body 302 and limit sealing plates 301 provided at both ends of the rod body 302. The rod body 302 passes through the through hole with a gap, and the limit sealing plates 301 limit the rod body 302 from detaching from the through hole. When the lifting rod 2 is rotated by the wrench rod 3, if there are obstacles affecting the wrench rod 3, the wrench rod 3 can be moved to the other side to avoid the obstacles.

[0042] As Figure 6 shown, the chassis 4 includes a first connecting plate 401 and a cylinder body 403. The inner wall of the cylinder body 403 is provided with an internal thread corresponding to the external thread of the adjusting rod 201; the first connecting plate 401 is circular, the cylinder body 403 is vertically fixed on the first connecting plate 401, and the first connecting plate 401 is provided with a circular hole corresponding to the cylinder body 403 for the adjusting rod 201 to pass through; preferably, a number of reinforcing gussets 402 are also installed between the outer wall of the cylinder body 403 and the first connecting plate 401. Preferably, a hole 404 for adding lubrication to the internal thread of the cylinder body is also provided on the side wall of the cylinder body.

[0043] As Figure 7 shown, the base 5 includes a second connecting plate 501 and an adjusting cylinder body 503. The adjusting cylinder body 503 is vertically installed on the second connecting plate 501. The second connecting plate is circular. The second connecting plate 501 is provided with a circular hole for the adjusting rod 201 to pass through corresponding to the adjusting cylinder body 503. A bottom plate 502 is installed at the opposite end of the adjusting cylinder body connecting the second connecting plate to seal the end of the cylinder body; the first connecting plate and the second connecting plate are connected and fixed by a connecting member 6. The connecting member 6 is such as a bolt. Correspondingly, circular holes for installing the connecting member 6 are provided on the circumferential edge of the first connecting plate and the circumferential edge of the second connecting plate. When the height required to support the pier exceeds the adjustment range of the lifting rod, a longer adjusting cylinder body can be replaced to make up for the insufficient adjustment range.

[0044] In the assembled form, the baffle 202 is not installed first. The adjusting rod 201 is passed through the cylinder body 403 and the first connecting plate 401 and then the baffle 202 is installed. Then, the chassis 4 and the base 5 are aligned and fitted through the first connecting plate 401 and the second connecting plate 501 and then connected and fixed by the connecting member 6.

[0045] This embodiment is only a further explanation of the present utility model and does not limit the present utility model. After reading this specification, those skilled in the art can make non-creative modifications to this embodiment as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
