[0002] In power plant construction, the heat absorption tower is a crucial landmark structure, and its construction quality is of paramount importance. Traditional formwork construction methods for large concrete cylinder walls suffer from problems such as complex construction procedures, low efficiency, and the need for a large amount of manpower. To improve construction efficiency, slipform construction technology has gradually been adopted, which not only increases the speed of concrete construction but also greatly saves labor.

[0003] However, a significant challenge in slipform construction is that the lifting device may twist during operation or tilt due to uneven lifting force, leading to tilting of the concrete cylinder. This seriously affects the construction quality. Currently, existing construction methods cannot monitor the slipform lifting process in real time and accurately, and cannot detect and correct the deviation problem in a timely manner. To solve the above-mentioned problems, a slipform construction detection system for heat absorption tower cylinder walls is proposed. Utility Model Content

The pitch angle fine-tuning unit is disposed on the XY linear motion unit, and the laser calibrator is disposed on the pitch angle fine-tuning unit to realize the adjustment of the laser calibrator in the X, Y and Z axis directions.

[0014] Furthermore, the four positioning target plate assemblies are arranged circumferentially at intervals on the outer peripheral surface of the heat absorption tower slide; and the positions of the four laser calibration components correspond to the positions of the four positioning target plate assemblies.

[0015] Furthermore, the four positioning target plate assemblies are respectively positioned in front of, behind, and on the left and right sides of the heat absorption tower.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-3 This utility model provides a sliding formwork construction inspection system for the wall of a heat absorption tower. First, at least two laser calibration components 1 and at least two positioning target plate components 2 are prepared.

[0027] During assembly, at least two positioning target plate assemblies 2 are arranged circumferentially on the outer periphery of the heat absorption tower tube slide;

[0028] At the same time, the positions of the two laser calibration components 1 are adjusted to correspond to the positions of at least two positioning target components 2, so that the irradiation direction of the laser calibration components 1 is perpendicular to the positioning target components 2. When the laser point is adjusted to the center point of the positioning target components 2, the laser calibration components 1 are fixed and locked.

[0029] The irradiation beams of two adjacent laser calibration components 1 are arranged in parallel on the top view to form a four-directional symmetrical parallel detection system, thereby realizing the detection of the offset of the heat absorption tower in any direction.

[0030] For details, please refer to Figure 3 The positioning target plate assembly 2 includes a plate body 21, and scale lines 22 are formed on the plate body 21. The irradiation direction of the laser calibration assembly 1 is set perpendicularly to the center point of the scale lines 22. It can accurately determine the offset direction and offset amount of the sliding mode device during the lifting process by the offset of the position of the light spot projected on the target plate 21 by the laser calibration assembly 1, and provide accurate data support for timely correction measures.

[0031] For details, please refer to Figure 3 The plate body 21 is made of hard stainless steel, and the scale lines 22 on its surface are engraved by a high-precision machine tool. It has high precision and durability, and can keep the scale lines 22 clearly visible in the outdoor working environment for a long time, ensuring the accuracy and reliability of the test.

[0032] For details, please refer to Figure 2 Each laser calibration component 1 consists of a laser calibrator 11 and a fine-tuning structure 12. During assembly, the laser calibrator 11 is first installed on the fine-tuning structure 12 to ensure that the installation is firm and will not shake during the adjustment process. The laser calibrator 11 can be adjusted with the movement of the fine-tuning structure 12 to adjust its irradiation direction, which facilitates the initial positioning and adjustment of the laser point and the center of the target plate.

[0033] For details, please refer to Figure 2 The fine-tuning structure 12 includes a pitch angle fine-tuning unit 121 and an XY linear motion unit 122. The laser calibrator 11 is specifically installed on the pitch angle fine-tuning unit 121 on the fine-tuning structure 12, and the pitch angle fine-tuning unit 121 is installed on the XY linear motion unit 122. After the connection of each component is completed, debugging is carried out to ensure that the laser calibrator 11 can be flexibly adjusted in the X, Y and Z axis directions through the fine-tuning structure 12.

[0034] For details, please refer to Figure 1 Four positioning target plate assemblies 2 are arranged circumferentially on the outer circumferential surface of the heat absorption tower slide; and the positions of the four laser calibration components 1 correspond to the positions of the four positioning target plate assemblies 2.

[0035] For details, please refer to Figure 1 The four positioning target plate assemblies 2 are respectively set in front of, behind and on the left and right sides of the heat absorption tower.

[0036] In this embodiment, by increasing the number of positioning target plate components 2 and the corresponding number of laser calibration components 1 to four and setting them in the positions of front, rear and left and right sides, the detection range of the heat absorption tower can be improved and the comprehensiveness of the detection can be enhanced.

[0037] For details, please refer to Figure 2 It also includes a detection unit 3, which is a manual aiming scope, with the aiming scope facing the positioning target plate assembly 2;

[0038] or

[0039] The detection unit 3 is a detection camera, which is directed toward the positioning target assembly 2 and is used to monitor the position of the light spot emitted by the laser calibrator 11 on the positioning target assembly 2.

[0040] In this embodiment, when assembling the system, the detection unit 3 can be selected according to actual needs to achieve diverse assembly requirements. If a manual aiming scope is selected, it is necessary to ensure that the aiming scope has a clear field of view and meets the accuracy requirements. If a detection camera is selected, it is necessary to equip it with a suitable lens to ensure that the shooting direction can be accurately oriented towards the positioning target plate assembly 2, and that the camera's resolution and shooting frame rate can meet the detection requirements.

[0041] Working principle

[0042] During the slipform construction of the heat absorption tower, this detection system is used regularly for testing. The laser calibrator 11 continuously emits a laser beam to irradiate the positioning target plate assembly 2, and the position of the laser spot on the scale line 22 of the positioning target plate is observed through the detection unit 3.

[0043] If the light spot deviates from the center point of scale line 22, it indicates that the heat absorption tower has shifted in the corresponding direction. Based on the distance and direction of the light spot deviation, combined with the scale value of scale line 22, the tower's offset can be calculated. For example, if the light spot deviates from the center point by one scale mark in the horizontal direction, with each scale mark representing one millimeter, it can be determined that the tower has shifted by one millimeter in the horizontal direction. Based on the detected offset, the construction personnel promptly adjust the parameters of the slipform construction, such as adjusting the tension in the opposite direction of the template offset and adjusting the lifting speed of the slipform in different positions, to correct the tower's offset and ensure construction quality.

[0044] Meanwhile, the time and offset of each test are recorded for subsequent construction analysis and quality assessment. Throughout the construction process, the tower offset is continuously monitored to ensure construction safety and that the tower's verticality meets design requirements.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
