Description

Technical Field

[0001] The invention relates to a height adjustment device, in particular to an adjustment device for a pressure-bearing wooden pier of an LNG ship. Background Art

[0002] Pressure-bearing wooden piers are widely used on LNG ships to transfer the force generated by the cargo tank to the main hull. The traditional installation method of pressure-bearing wooden piers is to open bolt holes on the saddle bottom plate and pass the jacking bolts through the bolt holes to adjust the height of the wooden pier. This method is time-consuming and labor-intensive, and the holes in the base affect the strength of the base. It is only applicable to ships with independent saddles, but not to LNG ships with independent A-type tanks. Summary of the invention

[0003] The purpose of the present invention is to design a device for LNG ship pressure-bearing wooden piers which is strong, easy to adjust, has a wider range of applications, and can adjust the height and fix the height.

[0004] The object of the present invention is achieved in that:

[0005] An adjustment device for a pressure-bearing wooden pier of an LNG ship comprises a vertical adjustment screw 1, an adjustment sleeve 2, a lateral adjustment screw 3, a height positioning nut 4, a positioning pad 5, and a supporting bracket 6.

[0006] The lateral adjustment screw 3 includes a spiral portion and a support portion. One end of the support portion is vertically fixedly connected to the side of the adjustment sleeve 2, and the other end extends out in the form of a screw to form the spiral portion. A fastening double nut 7 is provided on the spiral portion. A supporting toggle plate 6 is provided between the lower part of the support portion and the adjustment sleeve 2. The lateral adjustment screw is installed on the side of the pressure-bearing wooden pier through the spiral portion.

[0007] The inner wall of the adjusting sleeve 2 is provided with a thread matching the vertical adjusting screw 1. The adjusting sleeve 2 is threadedly connected to the vertical adjusting screw 1 and both are vertically arranged. The height positioning nut 4 is arranged between the top of the adjusting sleeve 2 and the head of the vertical adjusting screw 1, and the positioning pad 5 is padded below the vertical adjusting screw 1.

[0008] Furthermore, a spherical pit is provided at the center of the positioning pad 5, and the bottom end of the vertical adjustment screw 1 is a spherical surface, the size of which is smaller than the spherical pit. The end of the vertical adjustment screw is pressed against the spherical pit of the positioning pad to prevent the vertical adjustment screw from being displaced during use.

[0009] Furthermore, the radius of the spherical surface is 3-10 mm, and the taper is 60-180°.

[0010] Furthermore, the positioning pad 5 is square.

[0011] Furthermore, the positioning pad 5 also includes baffles 9 arranged at four corners and protruding from the outer edge, and anti-slip material is arranged below the protruding part of the baffle 9.

[0012] Furthermore, the anti-slip material is an anti-slip rubber strip 8.

[0013] Furthermore, the vertical adjustment screw 1 is an external hexagonal screw.

[0014] Furthermore, the support portion and the adjustment sleeve 2 are connected by welding.

[0015] The beneficial effects of the present invention are as follows: the installation process is simple, the positioning accuracy is high, the strength of the saddle is not affected, the service life of the saddle is improved, the operation is convenient, and the requirement that the positioned wooden piers need to be lifted and then reinstalled when the independent A-type tank is installed on the pressure-bearing wooden piers can be met, thereby reducing the construction difficulty.

DETAILED DESCRIPTION

[0020] The above technical features and advantages of the present invention are described in more detail below in conjunction with embodiments.

[0021] like Figure 1-3 As shown, an adjustment device for a pressure-bearing wooden pier of an LNG ship comprises a vertical adjustment screw 1, an adjustment sleeve 2, a lateral adjustment screw 3, a height positioning nut 4, a positioning pad 5, and a supporting bracket 6.

[0022] The lateral adjustment screw 3 includes a spiral portion and a support portion. One end of the support portion is vertically fixedly connected to the side of the adjustment sleeve 2, and the other end extends out in the form of a screw to form the spiral portion. A fastening double nut 7 is provided on the spiral portion. A supporting toggle plate 6 is provided between the lower part of the support portion and the adjustment sleeve 2. The lateral adjustment screw is installed on the side of the pressure-bearing wooden pier through the spiral portion.

[0023] The inner wall of the adjusting sleeve 2 is provided with a thread matching the vertical adjusting screw 1. The adjusting sleeve 2 is threadedly connected to the vertical adjusting screw 1 and both are vertically arranged. The height positioning nut 4 is arranged between the top of the adjusting sleeve 2 and the head of the vertical adjusting screw 1, and the positioning pad 5 is padded below the vertical adjusting screw 1.

[0024] The center of the positioning pad 5 is provided with a spherical pit, and the bottom end of the vertical adjustment screw 1 is a spherical surface, the size of which is smaller than the spherical pit. The end of the vertical adjustment screw is supported in the spherical pit of the positioning pad to prevent the vertical adjustment screw from being displaced during use.

[0025] The radius of the spherical surface is 3-10 mm, and the taper is 60-180°.

[0026] The positioning pad 5 is square.

[0027] The positioning pad 5 further includes baffles 9 which are arranged at four corners and protrude from the outer edge, and anti-slip material is arranged below the protruding portion of the baffle 9 .

[0028] The anti-skid material is an anti-skid rubber strip 8 .

[0029] The vertical adjustment screw rod 1 is an external hexagonal screw rod.

[0030] The support portion and the adjusting sleeve 2 are connected by welding.

[0031] The adjustment device for the pressure-bearing wooden pier of the LNG ship is realized as follows: first, the lateral adjustment screw 3 is passed through the fastening double nut and then installed into the threaded hole on the side of the pressure-bearing wooden pier, and then the fastening double nut 7 is locked to connect the lateral adjustment screw 3 and the pressure-bearing wooden pier into a whole, and the vertical adjustment screw 1 is pushed into the spherical pit of the positioning pad 5 through the height positioning nut 4 and the adjustment sleeve 2, and the vertical adjustment screw 1 is screwed in and out of the adjustment sleeve 2 by a wrench to adjust the height of the pressure-bearing wooden pier. After adjusting to the required height, tighten the height positioning nut to fix the height, so as to achieve the purpose of ensuring that the height of the pressure-bearing wooden pier remains unchanged when the pressure-bearing wooden pier is lifted and reinstalled.

[0032] The invention has a simple installation process, high adjustment accuracy, does not affect the strength of the saddle, has a wider application range, and is easy to operate.
