The main components of the water-cooled wall include tube panels (modules composed of multiple steel pipes), fins (used to increase the heat exchange area and connect adjacent steel pipes), support structures, and inlet and outlet headers. Among them, the tube panel is the core part of the water-cooled wall, which not only bears the task of heat transfer, but also directly relates to the stable operation of the entire system.

However, in this process, it is essential to maintain uniform gap width between adjacent tube panels. If the gap width is not uniform, it will not only bring difficulties to the subsequent welding work and increase the risk of welding defects, such as incomplete fusion of the weld, porosity, etc., directly affecting the overall strength and service life of the water-cooled wall, but also cause uneven distribution of thermal stress during use, and the expansion of each part of the water-cooled wall will be different, resulting in local stress concentration, which may cause material fatigue or rupture over a long period of time. Therefore, a special spacing adjustment device is needed to adjust the spacing between adjacent tube panels during welding.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The embodiments in the present application and the features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] As shown in Figures 1-7 , the present application provides a water cooling wall pipe screen spacing adjusting device, which comprises:

[0027] The U-shaped support 1; two pipe plug assemblies 2, adjustable spacing symmetrically arranged at the opening end of the U-shaped support 1, used for inserting into the pipe lumen of the adjacent tube panel 3; an adjusting member 4 arranged on the U-shaped support 1, used for adjusting and locking the spacing of the two pipe plug assemblies 2, and a scale line 5 arranged on the sealing end face of the U-shaped support 1 for measuring the spacing of the two pipe plug assemblies 2; a plurality of movable supporting tables 6 are arranged on the bottom of the tube panel 3, used for supporting the tube panel 3 and reducing the friction with the ground.

[0028] When two tube panels 3 need to be welded, first place the tube panel 3 on the movable supporting table 6, so that the two tube panels 3 are at the same horizontal height and can easily move relative to each other under a certain pushing force, then insert the pipe plug assemblies 2 into the two ends of the adjacent pipes of the two tube panels 3, at this time the two tube panels 3 can be considered as being connected as a whole, then adjust the spacing of the two pipe plug assemblies 2 by using the adjusting member 4, and the spacing of the pipe plug assemblies 2 at both ends of the tube panel 3 needs to be ensured to be the same by reading the scale line 5, in the process of adjusting the spacing of the pipe plug assemblies 2, the pipe plug assemblies 2 drive the two tube panels 3 to move relative to each other, by adjusting the spacing of the pipe plug assemblies 2, the width of the gap at both ends of the two tube panels 3 is the same, and since the tube panel 3 can be considered as flat in the axial direction of the pipe, therefore the overall gap width of the two tube panels 3 can be considered as uniform.

[0029] In an embodiment, the pipe plug assembly 2 includes a plug head 21 for inserting into the end of the pipe in the tube panel 3 and a connecting rod 22 fixedly arranged at the end of the plug head 21. The adjusting member 4 includes a bidirectional screw rod 41 rotatably arranged on the U-shaped support 1 and threadedly penetrating the two connecting rods 22, a guide limiting rod 42 fixedly arranged on the U-shaped support 1 and penetrating the two connecting rods 22, and a driving member 43 arranged on the U-shaped support 1 for driving the bidirectional screw rod 41 to rotate, and the screw threads of the penetrating portions of the bidirectional screw rod 41 and the two connecting rods 22 are opposite in rotation direction.

[0030] In this way, the bidirectional screw rod 41 is driven to rotate by the driving member 43, and the bidirectional screw rod 41 drives the two connecting rods 22 and the plug heads 21 to move in opposite directions while rotating, the guide limiting rod 42 provides limiting and guiding for the movement of the two connecting rods 22, ensuring smooth movement, and the two plug heads 21 move in opposite directions, the distance changes, and the tube panel 3 inserted into the plug heads 21 moves together.

[0031] In an embodiment, the driving member 43 includes a worm gear 431 coaxially fixedly arranged in the middle of the bidirectional screw rod 41, a worm shaft 432 rotatably arranged on the U-shaped support 1 and meshing with the worm gear 431, and a wheel disc 433 fixedly arranged at the end of the worm shaft 432.

[0032] In this way, the rotating wheel 433 can drive the worm 432 to rotate, the worm 432 drives the worm wheel 431 to rotate together with the bidirectional screw rod 41 through the meshing of the gear teeth, so that the driving of the rotation of the bidirectional screw rod 41 is realized. In addition, due to the self-locking characteristic of the meshing of the worm wheel 431 and the worm 432, the bidirectional screw rod 41 will not rotate when no rotating torque is applied to the rotating wheel 433, that is, the spacing of the two pipe plug assemblies 2 on the same U-shaped support 1 will not change.

[0033] In an embodiment, a pointer 7 is fixedly arranged on the connecting rod 22, and the tip of the pointer 7 points to the scale line 5.

[0034] In this way, the spacing of the two pipe plug assemblies 2 can be more clearly read.

[0035] In an embodiment, a lifting handle 8 is fixedly arranged at the top of the two sides of the U-shaped support 1.

[0036] In this way, when the pipe plug assembly 2 and the pipe screen 3 are inserted, the entire U-shaped support 1 and the remaining structures arranged on the U-shaped support 1 are lifted through the lifting handle 8, so that the whole is in a suspended state, facilitating the insertion operation.

[0037] In an embodiment, the moving support table 6 includes a bottom disc support 61, a plurality of rollers 62 arranged at the bottom of the bottom disc support 61, and a clamping plate 63 fixedly arranged at the top of the bottom disc support 61, and the clamping plate 63 is clamped with the bottom of the pipe screen 3.

[0038] In this way, the pipe screen 3 is placed on the moving support table 6, and the bottom surface is clamped with the clamping plate 63, so that the pipe screen 3 is stably supported. When a certain horizontal external force is applied to the pipe screen 3 or the moving support table 6, the rollers 62 can roll on the ground, thereby driving the pipe screen 3 to move.

[0039] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.

[0040] It should be noted that if the present application embodiments involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship, movement condition, etc. between the components in a certain specific posture, and if the specific posture changes, the directional indications will also change accordingly.

[0041] In addition, "multiple" refers to two or more. In addition, the technical solutions among various embodiments can be combined with each other, but must be based on the fact that a person of ordinary skill in the art can realize it, and when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of such technical solutions does not exist, nor is it within the protection scope required by the utility model.
