Technical Field

[0001] The utility model relates to the technical field of solar power generation construction, in particular to a tank steel plate welding correction device. Background Art

[0002] At present, the construction scale of tower solar thermal power stations is relatively large, the heat storage time is longer, and the capacity and technical parameter requirements of the corresponding molten salt storage tanks are also increased, so the construction quality requirements of the tank body are also higher. The tank body is usually surrounded by multiple steel plates arranged in sequence, with welding seams between adjacent steel plates, and the welding process is used to seal and fix the welding seams.

[0003] At present, the commonly used tank steel plate welding process is on-site manual welding. Because the tank steel plates are usually thicker, the traditional on-site lifting installation and the use of the chain-back correction process are inconvenient to operate, which can easily cause the outer edges of the welding seams between adjacent tank steel plates to be not in the same plane, resulting in uneven openings on the outer sides of the welding seams, and inconsistent spacing between multiple groups of adjacent tank steel plates, resulting in different spacing between welding seam widths. These problems leave certain quality risks for the welding of the welding seams, reduce the welding efficiency of the workers, affect the overall installation progress, and increase construction costs.

[0005] In view of the above technical problems, the technical solution provided by the utility model is a tank steel plate welding correction device, including a correction mechanism and two correction blocks, the two correction blocks are used to be placed on two adjacent tank steel plates along the left-right direction, the correction mechanism includes a correction plate, a transverse correction unit and a longitudinal correction unit, a correction groove is opened on the front side of the correction plate corresponding to the positions of the two correction blocks, the rear parts of the two correction blocks are used to penetrate into the correction groove, the transverse correction unit is used to drive the correction block to slide in the correction groove along the left-right direction to adjust the left-right spacing between the two correction blocks, and the longitudinal correction unit is used to correct the front and rear positions of the two correction blocks so that the rear sides of the two correction blocks are aligned.

[0006] Furthermore, a correction hole extending vertically is provided at the upper end of the correction plate, the correction hole is arranged in communication with the correction groove, the rear of the correction block extends into the correction hole and an adjustment gap is left between the two, a plug hole is provided at the rear of the correction block, the longitudinal correction unit includes two longitudinal correction wedge plates, the lower ends of the longitudinal correction wedge plates are inserted into the plug holes on the corresponding sides, and the transverse correction unit includes at least one transverse correction wedge plate, which is inserted into the gap between the correction block and the correction hole in the left and right directions.

[0007] Furthermore, the upper ends of the longitudinal correction wedge plate and the transverse correction wedge plate are both provided with a step structure.

[0008] Furthermore, two correction holes are arranged on the correction plate at intervals along the left-right direction, and the two correction holes correspond to the positions of the two correction blocks one by one.

[0009] Furthermore, the correction plate includes a connecting plate, and a U-shaped notch is respectively arranged on the front side of the connecting plate corresponding to the positions of the two correction blocks, and a U-shaped clamping plate for blocking the U-shaped notch is arranged on the U-shaped notch, and the U-shaped clamping plate and the U-shaped notch form the correction hole, and the correction groove is opened on the front side surface of the U-shaped clamping plate.

Then, the spacing between any two adjacent tank steel plates can be adjusted to be consistent.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application: Specific embodiment 1:

[0024] In this embodiment, if Figure 5 As shown, the left-right direction is the spacing direction of the two tank body steel plates 1, the extending direction of the direction S is the front-to-back direction, and the tank body steel plates 1 and the correction plate 8 are spaced apart in the front-to-back direction.

[0025] In this embodiment, the tank body is surrounded by a plurality of tank body steel plates 1, and then fixed into a whole by welding. Figure 1 As shown, a welding seam 2 is formed between adjacent tank body steel plates 1 .

[0026] like Figures 1 to 5 As shown, a tank steel plate welding correction device (hereinafter referred to as the correction device) of the utility model includes a correction mechanism and two correction blocks 3, wherein the two correction blocks 3 are disposed on two adjacent tank steel plates 1 along the left-right direction, and the two correction blocks 3 are symmetrically arranged on both sides of the welding seam 2 along the left-right direction.

[0027] like Figure 1 , 4 As shown, the correction mechanism includes a correction plate 8, a transverse correction unit 4 and a longitudinal correction unit 5, wherein the correction plate 8 is arranged vertically with the tank body steel plate 1, and the front side of the correction plate 8 corresponds to the position of the two correction blocks 3, and is provided with a correction groove 13 adapted to the correction block 3, and the rear parts of the two correction blocks 3 are used to penetrate into the correction groove 13 and slide left and right along the correction groove 13. The transverse correction unit 4 is used to drive the correction block 3 to slide in the correction groove 13 along the left and right direction to adjust the left and right spacing of the two correction blocks 3, and the longitudinal correction unit 5 is used to correct the front and rear positions of the two correction blocks 3 so that the rear side surfaces of the two correction blocks 3 are aligned.

[0028] Specifically, in this embodiment, a correction hole 14 extending downward along the vertical direction L is opened at the upper end of the correction plate 8, and the correction hole 14 is arranged to be connected with the correction slot 13, so that the rear part of the correction block 3 can enter the correction hole 14 from the correction slot 13, and the size of the correction hole 14 is larger than that of the correction block 3, so that an adjustment gap is left between the correction hole 14 and the correction block 3.

[0029] The longitudinal correction unit 5 includes two longitudinal correction wedge plates 7, the lower ends of the longitudinal correction wedge plates 7 are provided with sharp corners, and the front side surfaces thereof are arranged parallel to the welding seam 2, such as Figure 1 , 2 As shown, a plug hole 15 adapted to the longitudinal correction wedge plate 7 is opened at the rear of the correction block 3, and the lower ends of the two longitudinal correction wedge plates 7 are respectively inserted into the plug holes 15 on the corresponding sides along the vertical direction L.

[0030] In this way, in actual use, firstly, the correction block 3 is made to penetrate into the correction hole 14 through the correction groove 13. When the front and rear positions of the two tank steel plates 1 are not aligned, the positions of the two plug holes 15 in the correction hole 14 are also not aligned. At this time, the longitudinal correction wedge plate 7 is inserted into the corresponding plug hole 15. Afterwards, under the condition that the correction plate 8 is vertical to the tank steel plate 1, the correction plate 8 is pulled or the tank steel plate 1 is moved so that the two longitudinal correction wedge plates 7 are both in contact with the front edge of the correction hole 14. At this time, the two correction blocks 3 are driven to move relative to each other in the front and rear directions, so that the rear side surfaces of the two correction blocks 3 are aligned, and then the front and rear relative positions of the two tank steel plates 1 are adjusted to control the flatness of the interface between the two tank steel plates 1.

[0031] Preferably, in this embodiment, the distance between the front side of the correction block 3 and its plug hole 15 is adapted to the depth of the correction groove 13. In this way, in actual use, the correction block 3 is firstly inserted into the correction hole 14 through the correction groove 13, and the front side of the correction plate 8 is contacted with the tank body steel plate 1. When the two tank body steel plates 1 are not aligned in the front-to-back direction, the plug hole 15 of the correction block 3 on the relatively rear side is just exposed in the correction hole 14, and the longitudinal correction wedge plate 7 is inserted into the plug hole 15 to position and fix the tank body steel plate 1 on this side. The two tank body steel plates 1 can be aligned by moving the tank body steel plate 1 on the other side and wedging the longitudinal correction wedge plate 7 on this side, thereby ensuring the flatness of the interface between the two tank body steel plates 1 and improving the working efficiency.

[0032] In this embodiment, the transverse correction unit 4 includes a transverse correction wedge plate 6, which is used to be inserted into the left-right gap between one side correction block 3 and the correction hole 14, and the inclined surface of the transverse correction wedge plate 6 is arranged away from the correction block 3. In this way, by adjusting the insertion depth of the transverse correction wedge plate 6, the side correction block 3 can be driven to slide in the correction groove 13, thereby changing the relative position of the two correction blocks 3 in the left-right direction, adjusting the width of the welding seam 2, ensuring that the spacing between any two adjacent tank steel plates 1 is adjusted to be consistent, ensuring the subsequent welding effect, and reducing the welding difficulty and ensuring the installation progress.

[0033] Preferably, in this embodiment, in order to facilitate the insertion of the longitudinal correction wedge plate 7 and the transverse correction wedge plate 6, the upper ends of the longitudinal correction wedge plate 7 and the transverse correction wedge plate 6 are both provided with a step structure 16.

[0034] Preferably, in this embodiment, two correction holes 14 are arranged on the correction plate 8 at intervals along the left-right direction, and the two correction holes 14 correspond to the positions of the two correction blocks 3 one by one. In this way, in actual use, the lateral correction wedge plate 6 can be conveniently inserted into the corresponding side of the corresponding correction hole 14, which is more convenient to adjust the spacing between the two correction blocks 3. Of course, in other embodiments, the number of lateral correction wedge plates 6 can be set to 2 according to actual needs. In this case, the two lateral correction wedge plates 6 can be used to synchronously adjust the left-right positions of the two correction blocks 3 to improve practicality.

[0035] Preferably, Figure 3 , 4 As shown, in this embodiment, the correction plate 8 includes a connecting plate 9, and a U-shaped notch 10 is respectively arranged at the front side of the connecting plate 9 corresponding to the position of the two correction blocks 3, and a U-shaped clamping plate 12 is arranged on the U-shaped notch 10 to block the U-shaped notch 10. The U-shaped clamping plate 12 and the U-shaped notch 10 surround a correction hole 14, and a correction groove 13 is provided on the front side of the U-shaped clamping plate 12, and the upper end of the U-shaped clamping plate 12 is higher than the upper end surface of the connecting plate 9. In this way, the correction plate 8 is designed in a split manner, which is convenient for processing and manufacturing on the one hand, and convenient for correction using the U-shaped clamping plate 12 on the other hand.

[0036] In this embodiment, preferably, a notch structure 11 is provided in the middle of the front side of the connecting plate 9, the notch structure 11 is in the shape of a "convex" character, and the notch structure 11 is arranged at the welding seam 2. The notch structure 11 can be used to facilitate observation of the correction situation.

[0037] The use process of the correction device of the utility model is:

[0038] like Figure 5 As shown, firstly, a correction block 3 is temporarily welded and fixed at the corresponding positions on both sides of the welding seam 2, and the two correction blocks 3 are arranged symmetrically relative to the welding seam 2.

[0039] The correction plate 8 is moved forward along the assembly direction S, and the correction block 3 is inserted into the corresponding correction groove 13 .

[0040] By inserting the longitudinal correction wedge plate 7 into the plug hole 15 of the two correction blocks 3 along the vertical direction L, the front and rear positions of the two tank steel plates 1 are adjusted so that the outer edges of the welding seams 2 are in the same plane and the outer openings of the welding seams 2 are smooth, thereby controlling the flatness of the interface between the two tank steel plates 1.

[0041] By inserting the transverse correction wedge plate 6 into the left-right gap between the correction block 3 on one side and the correction hole 14, the left-right spacing between the two tank steel plates 1 is adjusted, and the width of the tank welding seam 2 is adjusted. The correction is completed to meet the welding requirements of the welding seam 2.

[0042] According to the above steps, the front and rear positions and the spacing between any two adjacent tank body steel plates 1 are adjusted in sequence to complete the tank body welding correction.

[0043] In summary, the correction device of the present invention, by fixing the two correction blocks 3 on the two tank steel plates 1 respectively, can drive the correction block 3 to slide in the correction groove 13 along the left and right direction by using the lateral correction unit 4, so as to adjust the left and right spacing between the two correction blocks 3. During the movement of the correction block 3, the corresponding tank steel plate 1 can be driven to move synchronously, thereby adjusting the spacing between the two tank steel plates 1, adjusting the width of the welding seam 2, and then adjusting the spacing between any two adjacent tank steel plates 1 to be consistent.

[0044] The longitudinal correction unit 5 can be used to adjust the front and rear positions of the correction block 3 so that the rear sides of the two correction blocks 3 are aligned. Then, the outer edges of the welding seams 2 between the adjacent tank steel plates 1 can be in the same plane, ensuring that the outer openings of the welding seams 2 are smooth, controlling the flatness of the interfaces between the two tank steel plates 1, ensuring the subsequent welding effect, and reducing the difficulty of welding, ensuring the installation progress.

[0045] Embodiment 2: This embodiment provides a different correction mechanism. Different from Embodiment 1, in this embodiment, when meeting actual usage requirements, the correction plate is a whole plate-like structure, and correction holes may not be set on the correction plate. The correction groove runs through the front and back sides of the correction plate, and openings that pass through the correction groove are respectively set on the left and right sides of the correction plate.

[0046] In this embodiment, the transverse correction mechanism includes a transverse thread adjustment mechanism, and the longitudinal adjustment mechanism includes a longitudinal thread adjustment mechanism. The longitudinal adjustment mechanism includes a longitudinal thread hole arranged at the rear side of the two correction blocks, and a longitudinal adjustment bolt is threadedly connected to the longitudinal thread hole, and the rear large head end of the longitudinal adjustment bolt is exposed outside the correction block. When the longitudinal adjustment nut is tightened, the large head end of the longitudinal adjustment nut can abut against the correction plate and drive the correction block to move in the front-to-back direction. When the two tank body steel plates are aligned with the front side of the correction plate, the front-to-back position correction of the two tank body steel plates is completed.

[0047] The transverse thread adjustment mechanism includes transverse threaded holes arranged on opposite sides of the two correction blocks and transverse adjustment bolts threadedly connected to the transverse threaded holes. The large head end of the transverse adjustment bolt is exposed on the corresponding side of the correction plate, and when the transverse adjustment nut is tightened, the large head end of the transverse adjustment nut can abut against the side surface of the correction plate and drive the correction block to move in the left and right direction, thereby adjusting the width of the welding seam.

[0048] Example 3: This example provides a different correction plate. Different from Example 1, in this example, when meeting actual usage requirements, the correction plate is a whole plate-like structure, and only one correction hole may be provided. At this time, the left and right widths of the correction hole are adapted to the left and right spacing between the two correction blocks, and the correction groove is provided on the front side of the correction block and passes through the correction hole.

[0049] Example 4: This example provides a different correction plate. Different from Example 1, in this example, when meeting actual usage requirements, the correction blocks may not be symmetrically arranged on both sides of the welding seam. In this case, the correction blocks may be staggered in height according to actual conditions. In this case, the shape of the correction hole is a Z-shaped groove that matches the positions of the two correction blocks.
