Description

Technical Field

[0001] The utility model relates to the technical field of butt plate welding, in particular to a device for real-time monitoring of the welding deformation amount of the butt plate of a tank. Background Technique

[0002] During the construction period of chemical plants in the petrochemical smelting industry, the number of tanks installed is large, the task volume is large, and the construction period is tight. After the installation and alignment of the steel plates of the tank shell, a large amount of welding technical work is carried out. The main quality control point of tank welding is the control of the deformation of the butt plate. At present, during the welding process of the butt plates of various types of tanks, conventional calipers and weld inspection rulers are generally used to measure the welding deformation amount of the butt plate. The biggest disadvantage of the existing measurement scheme is that real-time detection cannot be achieved. During the welding process, the welding operators cannot frequently use the measuring tools to detect the deformation. If the welding parameters are improper or the welding sequence method is incorrect, visible deformation may occur. At this time, it is too late to use the measuring tools again, and rework will inevitably occur, which is time-consuming, laborious and costly. Content of the Utility Model

[0003] The purpose of the utility model is to solve the problems existing in the prior art, and provide a device for real-time monitoring of the welding deformation amount of the butt plate of a tank, which can real-time monitor the welding deformation amount, has strong applicability, prevent the welding deformation in advance, and ensure the installation quality of the tank wall plate.

[0004] In order to achieve the above purpose, the utility model is realized through the following technical solutions:

[0005] A device for real-time monitoring of the welding deformation amount of the butt plate of a tank, including a reference bracket, on which two detection scales are arranged in sequence from front to back, and the distance between the two detection scales is adjustable. The bottom end of the detection scale extends out of the reference bracket. The middle part of the outer wall of the reference bracket is provided with a spirit level, and the angle of the spirit level is adjustable. The bottom of one end of the reference bracket is provided with a magnetic base.

[0006] Preferably, the spirit level can rotate 90°.

[0007] Preferably, the detection scale includes a scale sleeve and a scale arranged in the scale sleeve.

[0008] Preferably, an adjustment groove is arranged on the reference bracket along the length direction of the reference bracket. The scale sleeves of the two detection scales are both located in the adjustment groove and are slidably connected with the adjustment groove. A locking screw is arranged on the scale sleeve of the detection scale, and a waist-shaped hole adapted to the locking screw is arranged on the outer wall of the reference bracket. The waist-shaped hole is communicated with the adjustment groove.

[0009] Preferably, the width of the tail end of the scale is greater than the width of the other end of the scale.

[0010] Preferably, the reference bracket is a transparent frame.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. Strong applicability. For steel plates of different materials and thicknesses, the position of the monitoring device can be selected according to the weld orientation of the tank butt plate to ensure that the welding quality of various tanks is met.

[0013] 2. Easy to monitor relative deformation. The initial monitoring position can be adjusted by rotating the level bubble. The level bubble is centered in the horizontal or vertical direction. The positions of the two detection rulers can be adjusted and the initial scale readings can be recorded. During welding, the scale readings of the detection rulers can be observed to determine the relative welding deformation.

[0014] 3. Strong foresight. The real-time monitoring device is intended to prevent excessive welding deformation and control deformation before it happens. According to the real-time monitoring and detection scale data, the deformation cause is analyzed promptly and accurately, the welding process parameters are adjusted or anti-deformation measures are taken to ensure excellent welding quality, highlighting the foresight of welding operations.

[0015] 4. It can be used as a measuring tool to check the welding sequence. In the process of tank welding construction, jump welding, intermittent welding, or first longitudinal weld and then transverse weld are usually used. The utility model can be used as a measuring tool to check the actual effect of the basic welding sequence. The measuring device is placed according to the welding operation section to ensure that the welder observes the dynamic changes of the scale in the welding operation section to prevent obvious welding deformation and avoid a certain degree of rework.

[0016] 5. High economic benefits. The utility model is simple and practical, and can be used in conjunction with multiple sets of devices. It can monitor the device at a relatively low cost and play a highly efficient role, timely and accurately respond to the deformation deviation, and the welding personnel can quickly take corrective measures to avoid causing greater deformation and having to rework.

It includes a reference bracket 1, and two detection scales 2 are successively arranged on the reference bracket 1 from front to back, and the distance between the two detection scales 2 is adjustable. During use, the position of the detection scale 2 is adjusted so that the welding position 5 is located between the two detection scales 2.

[0024] The bottom end of the detection scale 2 extends out of the reference bracket 1. During use, the bottom end of the detection scale 2 abuts against the docking plate. A spirit level 3 is arranged in the middle of the outer wall of the reference bracket 1, and the angle of the spirit level 3 is adjustable. A magnetic base 4 is arranged at the bottom of one end of the reference bracket 1, and the magnetic base 4 and the reference 1 can be connected by screws.

[0025] Preferably, the spirit level 3 can rotate 90°. Whether the reference bracket 1 is in a horizontal state or a vertical state, the spirit level 3 can be adjusted to a horizontal state. For example, Figure 3 for the horizontally placed docking plate, both the spirit level 3 and the reference bracket 1 are in a horizontal state; for example, Figure 4 for the vertically placed docking plate, the reference bracket 1 is in a vertical state and the spirit level 3 is in a horizontal state. At this time, Figure 4 the spirit level 3 in Figure 3 rotates 90° for the spirit level 3 in

[0026] Preferably, the detection scale 2 includes a scale sleeve and a scale arranged in the scale sleeve. There are scales on the scale, and a first observation window for observing the scales is reserved on the scale sleeve.

[0027] Two adjusting screws can be arranged on the side of the scale sleeve away from the first observation window. Along the length direction of the reference bracket 1, a strip-shaped hole adapted to the adjusting screws is arranged on the reference bracket 1. When the adjusting screws are loosened, the adjusting screws can slide in the strip-shaped hole, and thus the position of the detection scale 2 can be adjusted.

[0028] Preferably, in order to ensure the stability of the detection scale, an adjustment groove 11 is provided on the reference bracket 1 along the length direction of the reference bracket 1. Both the upper and lower ends of the adjustment groove 11 are open. The sleeves of the two detection scales 2 are located in the adjustment groove 11 and are slidably connected to the adjustment groove 11. The sleeve is a rectangular sleeve. A locking screw 21 and a threaded hole adapted to the locking screw 21 are provided on the sleeve of the detection scale 2. A waist-shaped hole 12 adapted to the locking screw 21 is provided on the outer wall of the reference bracket 1. The waist-shaped hole 12 communicates with the adjustment groove 11. By tightening the locking screw 21, the position of the sleeve can be locked by the friction force between the head of the locking screw 21 and the reference bracket 1.
