Description

Technical Field

[0001] The present application relates to the field of shipbuilding equipment, and in particular to a temporary fixing device for single-folded-edge strakes. Background Art

[0002] Before welding the single-folded strakes of the LNG NO96 series ship containment system, the 50m long strakes must be accurately fixed on the insulation box and fixed firmly and effectively to leave enough equipment operation space for subsequent strake welding and firmly fix the welding position. When the equipment passes through the temporary fixing device, it needs to be able to be quickly and conveniently removed without affecting the normal operation of the welding equipment.

[0003] The single-folded edge temporary fixing tool currently used is a strut, one end of which is supported by a scaffolding board and the other end is supported on a single-folded edge row board. Since the row board is only 0.1mm thick, about 50m long and 500mm wide, about 40 struts are needed to fix it on the insulation box.

[0004] With regard to the above-mentioned related technologies, the inventor believes that the space for the welding equipment to operate is limited. About 40 struts are supported by the scaffolding board under the row board, and the numerous struts occupy the operation route of the welding equipment. The installation time is long. During the installation, more than 20 workers are required to accurately support more than 40 struts between the row board and the scaffolding at the same time, which requires a lot of manpower and time.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0026] The following is combined with Figure 1 This application is described in further detail.

[0027] The present application embodiment discloses a temporary fixing device for a single-edge column plate. Figure 1 A single-folded-edge column plate temporary fixing device includes an insulating box 1, the bottom wall of the insulating box 1 is a planar structure, and a fixing plate 2 is arranged below the insulating box 1, and a column plate 3 is arranged between the fixing plate 2 and the insulating box 1, and the fixing plate 2 and the insulating box 1 clamp and fix the column plate 3.

[0028] A pre-tightening assembly 4 is provided on the fixing plate 2, and the pre-tightening assembly 4 tightens the fixing plate 2 toward the side close to the insulating box 1, thereby driving the fixing plate 2 to have a tensioning force toward the side close to the insulating box 1, and then stably clamping the column plate 3 between the fixing plate 2 and the insulating box 1 through the fixing plate 2.

[0029] The length of the side wall of the fixed plate 2 close to the insulation box 1 along the horizontal direction is greater than the length of the side wall of the fixed plate 2 away from the insulation box 1 along the horizontal direction, so that the fixed plate 2 increases the connection area with the column plate 3 and improves the support strength of the column plate 3. The side of the fixed plate 2 close to the column plate 3 is fixedly connected with a protective rubber strip 21, and the protective rubber strip 21 completely wraps the top wall of the fixed plate 2, thereby separating the fixed plate 2 from the column plate 3, and the column plate 3 is protected by the protective rubber strip 21 to reduce the possibility of the column plate 3 being scratched.

[0030] The preload assembly 4 includes a latch tongue 41 , which is an “L”-shaped structure. The latch tongue 41 includes a horizontal portion 411 at the top, a vertical portion 412 vertically disposed at the bottom of the horizontal portion 411 , and the horizontal portion 411 is fixedly connected to the vertical portion 412 .

[0031] A first receiving groove 11 is provided on the bottom wall of the insulating box 1 at a position relative to the latch 41 , and a horizontal portion 411 at the top of the latch 41 extends into the first receiving groove 11 , and the top of the latch 41 is a horizontal structure, and the top of the latch 41 is fixedly connected to the insulating box 1 .

[0032] A second receiving groove 22 is provided at a position of the side wall of the fixing plate 2 relative to the latch tongue 41, and the vertical portion 412 of the latch tongue 41 extends into the second receiving groove 22. A pull rod 42 is provided inside the second receiving groove 22, and a connecting rod 43 is horizontally provided at the top end of the pull rod 42, and the connecting rod 43 is fixedly connected to the pull rod 42.

[0033] A through hole is horizontally opened on the vertical portion 412 of the tongue 41, and the through hole completely penetrates the side wall of the tongue 41. The connecting rod 43 is inserted into the through hole, and the side wall of the connecting rod 43 abuts against the side wall of the vertical portion 412 of the tongue 41, and the tongue 41 is connected to the pull rod 42 through the connecting rod 43 and the through hole.

[0034] A guide hole 23 is vertically opened at the position of the side wall of the fixed plate 2 relative to the pull rod 42, one end of the guide hole 23 is relatively connected to the inside of the second receiving groove 22, and the other end of the pull rod 42 is relatively connected to the outside. The end of the pull rod 42 extends from the inside of the guide hole 23, and the outer side wall of the pull rod 42 is relatively abutted and relatively slidably connected with the side wall of the guide hole 23 of the fixed plate 2. The guide hole 23 is provided to drive the pull rod 42 to move along the vertical height direction.

[0035] The side of the fixed plate 2 away from the column plate 3 is a planar structure, and an eccentric wheel 44 is provided on the side of the fixed plate 2 away from the column plate 3. The eccentric wheel 44 is a disc-shaped structure, and the outer circumferential side wall of the eccentric wheel 44 abuts against the side wall of the fixed plate 2 and rolls relatively.

[0036] The eccentric wheel 44 is opposite to the guide hole 23, and a handle 441 is fixedly connected to the outer side wall of the eccentric wheel 44, and the eccentric wheel 44 is driven to rotate relatively on the outer side wall of the fixed plate 2 by rotating the handle 441. The end of the pull rod 42 extending from the inside of the guide hole 23 is rotatably connected to the surface of the eccentric wheel 44, and the connection point between the pull rod 42 and the eccentric wheel 44 is eccentric to the rotation center of the eccentric wheel 44. Therefore, when the eccentric wheel 44 is driven to rotate by the handle 441, the eccentric wheel 44 can drive the pull rod 42 to move toward the side close to the insulation box 1 or away from the insulation box 1.

[0037] When the bottom end of the pull rod 42 is located on the side of the eccentric wheel 44 close to the insulating box 1, the pull rod 42 is at the highest point, thereby separating the insulating box 1 from the fixed plate 2; when the bottom end of the pull rod 42 is located on the side of the eccentric wheel 44 away from the insulating box 1, the pull rod 42 is at the lowest point, and the pull rod 42 tightens the latch 41, thereby tightening the fixed plate 2 and the insulating box 1 relative to each other, and then clamping and fixing the column plate 3 between the fixed plate 2 and the insulating box 1, thereby realizing the installation of the column plate 3.
