Description
Technical Field
[0001] The utility model relates to the technical field of ship hull manufacturing, in particular to a movable and adjustable pier tooling. Background Art
[0002] Gas carriers have saddle structures. In order to improve the overall assembly efficiency, the saddle structure will be combined with the double-bottom sections during the construction of the sections. To improve the efficiency of the sections, for double-bottom sections with straight or slightly curved outer plates, the sections will be laid down after the double-bottom structure is completed, and the structure on the double-bottom will be welded in the field after laying down. In order to reduce costs, no additional frame is built in the field, and four round piers are usually set up to support the sections. However, the cement floor in the field is not flat enough. The round piers were originally used with jacks to achieve the leveling of the base surface, which had low work efficiency and high safety hazards. When placing the sections, the round piers need to be placed with a forklift or a crane, and it is difficult to adjust the position. Due to the insufficient flatness of the ground, before the sections are positioned, they need to be leveled by a jack according to the accuracy data of the sections. Since the adjustment range of the jack is difficult to accurately control, thin steel plates or wooden boards are usually required for leveling, so the leveling accuracy is poor and the efficiency is low.

DETAILED DESCRIPTION
[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.
[0028] Reference Figure 1 As shown, the adjustable pier tooling described in the utility model comprises: an adjusting device 1, the adjusting device 1 comprises a top sleeve 11, a screw rod 12 and a threaded sleeve 13, the top sleeve 11 is connected to the end of the screw rod 12, the top sleeve 11 and the top of the screw rod 12 are put in place, and screws are screwed in, and the top sleeve 11 is relatively fixed while allowing the top sleeve 11 to move at a certain angle, so that the level can be adjusted; the threaded sleeve 13 is arranged on the outside of the screw rod 12, and two through grooves 131 are symmetrically arranged on the inner wall of the threaded hole of the threaded sleeve 13; a supporting device 2, connected to the screw rod 12 of the adjusting device 1; a lifting device 3, arranged on both sides of the supporting device 2, and a roller group 4 is also arranged at the bottom of the lifting device 2. The roller group 4 comprises a universal wheel and a fixed wheel, and a brake pad is arranged on the universal wheel.
[0029] like Figure 2 As shown, the top sleeve 11 and the threaded sleeve 13 are both provided with oil cups 14. The threaded sleeve 13 is also provided with lifting ears 15 on both sides.
[0030] like Figure 3 As shown, the screw rod 12 is provided with a plurality of adjustment planes 121 along the circumference, and the adjustment planes 121 are provided with round holes 122. The adjustment planes 121 are designed so that the screw rod 12 can be rotated by a wrench; the round holes 122 are designed so that the round steel can be inserted into the screw rod 12, and the height of the screw rod 12 can be adjusted by rotating the round steel.
[0031] like Figure 4 The threaded sleeve 13 shown has a through groove 131 in a V-shape. The through groove 131 can remove iron filings or small debris dropped during normal work, thereby minimizing the risk of the screw rod 12 being stuck.
[0032] like Figure 5As shown, the support device 2 includes a support fixing seat 21 and a round tube 22 arranged on the support fixing seat 21; the support fixing seat 21 includes a bottom plate 211, a connecting plate 212, a first rib plate 213, a second rib plate 214 and a top plate 215, the connecting plate 212 and the bottom plate 211 are arranged in parallel, and a first rib plate 213 is arranged between the connecting plate 212 and the bottom plate 211, a through hole matching the size of the round tube 22 is arranged at the center of the connecting plate 212, and second rib plates 214 are symmetrically arranged around the through hole on the connecting plate 212, and a top plate 215 is arranged on each of the second rib plates 214. A drainage hole is also arranged at the center of the bottom plate 211, and the drainage hole is smaller than the diameter of the round tube 22. The drainage hole can not only clean up the debris dropped on the screw rod 12, but also drain the rainwater flowing into the round tube 22 from the screw rod 12 on rainy days.
[0033] The supporting device 2 is fixed to the adjusting device 1 by welding. During installation, the bottom of the screw rod 12 and the top of the round tube 22 are welded together. The second rib plate 214 is welded and fixed to the lifting device 3. Since the part where the second rib plate 214 is connected to the lifting device 3 only needs to bear its own weight, the thickness of the second rib plate 214 is relatively thin. The bottom plate 211 and the first rib plate 213 need to bear the entire weight of the segment, so the thickness of the first rib plate 213 is relatively thick.
[0034] like Figure 6 As shown, the lifting device 3 includes a sleeve 31, a shaft pin 32, a spring 33 and a top cover 34. The sleeve 31 is connected to the support device 3. The shaft pin 32 is inserted in the sleeve 31. The outer side of the shaft pin 32 is provided with a spring 33. The end of the shaft pin 32 is connected to the top cover 34. The roller group 4 is connected to the bottom end of the shaft pin 32 through a fastener. During installation: the spring 33 is first put on the shaft pin 32, and then the sleeve 31 is put on, and then the top cover 34 is covered to limit the sleeve 31, and finally the roller is installed; then the sleeve 31 is welded together with the top plate 215, the second rib plate 214 and the connecting plate 212 of the support fixing seat 21, and the top plate 215 and the connecting plate 212 are provided with arc-shaped limiting grooves for limiting the sleeve 31. When the adjusting pier tooling is not subjected to external force, the spring 33 rises naturally. When subjected to external force, the spring 33 contracts when subjected to a certain pressure, and the middle support device 2 touches the ground. The subsequent force will be fully applied to the support device 2, and the second rib plate 214 connected to the lifting device 3 will only bear the force of the deformation of the spring 33.
[0035] Furthermore, the shaft pin 32 is provided with a keyway 321, and the shaft sleeve 31 is provided with a bolt 311, which extends into the keyway 321 and can reciprocate in the keyway 321. The shaft sleeve 31 has threads, and after the bolt 311 is tightened, it can move up and down in the keyway 321 of the shaft pin 32.
[0036] In addition, the shaft pin 32 is provided with a limiting step 322 for limiting the position of the spring 33 .
[0037] The roller group 4 in this embodiment includes a universal wheel and a fixed wheel, and a brake pad is provided on the universal wheel. The design of the roller group 4 can move the entire adjustment pier when it is not under pressure, which is very convenient. The load of the wheel is determined according to the deformation height of the entire adjustment pier and the spring 33. Generally, heavy loads (i.e., loads greater than 0.5t) are used. The spring 33 is also selected according to the weight of the adjustment pier itself. The height of the middle round tube 22 is based on the height it needs to support. It can be long or short, but it cannot be too high, resulting in poor stability of the entire device. When the lifting device 3 and the supporting device 2 are installed, the installation position needs to be adjusted according to the wheel height and the characteristics of the spring 33.
[0038] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
