Description

Technical Field

[0001] The present invention relates to the electric power field, and in particular to a device and a method for accurately measuring and controlling the concentricity of a heat-absorbing tower wall in a tower-type solar thermal project. Background Art

[0002] At present, the hydraulic platform jacking and mold turning process is used in the construction of the heat absorption tower wall structure, which is the landmark building of the tower solar thermal power generation project. As the heat absorption tower wall rises, the standard section of the construction elevator in the tower is lifted synchronously to ensure the vertical transportation of personnel and materials. The concentricity and verticality of the wall are the main control items of the heat absorption tower wall construction. After the completion of the heat absorption tower foundation and before the wall construction, the center position of the heat absorption tower will be accurately aligned again. After alignment, this center will be used as the standard section center of the construction elevator, and the construction elevator will be installed and lifted synchronously. At the same time, a laser plumb line is fixed at this center to control the concentricity and verticality of the heat absorption tower wall with the laser plumb line as the center. When measuring the concentricity of the wall, a transparent plate is set on the standard section frame of the construction elevator in the middle of the hydraulic platform. The geometric center of the heat absorption tower can be determined by the laser point hit on the transparent plate by the laser plumb line. With this center as the center of the circle, the radius from the center of the circle to the heat absorption tower wall template is measured and adjusted using a box ruler. Since the box ruler used in this method has a large measurement error (cm level), there is a high risk of human error, and it is also easily affected by obstacles, making it difficult to control the concentricity of the cylinder wall. There have been many cases of eccentricity in high tower buildings such as chimneys and heat-absorbing towers in China, causing great economic losses and safety hazards. Summary of the invention

After the laser rangefinder 14 is rotated, the laser rangefinder 16 no longer alarms, thereby ensuring the concentricity of the cylinder wall.

[0024] The sliding adjustable base 2 includes a slide rail 3, a level bubble 6, a through hole 7, a fixing screw 4, and a level adjustment screw 5.

[0025] A through hole 7 is opened at the center position of the sliding adjustable base 2, and two sections of slide rails are fixedly installed on the sliding adjustable base 2 along the y-axis direction.

[0026] The length of the sliding adjustable base 2 is 5-10mm greater than the length of the standard section frame 1 of the construction elevator. Two horizontal adjustment screws 5 are arranged at intervals along the x-axis direction on both ends of the top surface of the sliding adjustable base 2, and two fixing screws 4 are arranged at intervals along the x-axis direction on the side surface of the sliding adjustable base 2. The horizontal adjustment screws 5 and the fixing screws 4 are installed in the M6 ​​screw holes.

[0027] The manually adjustable rotating platform 10 comprises a rotating shaft 11. The manually adjustable rotating platform base 9 comprises a manual rotating knob 12 and a rotating locking knob 13.

[0028] A rotating shaft 11 is arranged at the center of the manually adjustable rotating platform 10 .

[0029] A manual rotating knob 12 and a rotating locking knob 13 are respectively provided on the manually adjustable rotating platform base 9. By rotating the manual rotating knob 12, the manually adjustable rotating platform 10 and the laser rangefinder 14 fixed thereon rotate simultaneously. The laser 15 emitted by the laser rangefinder 14 is directed toward the supporting position of the cylinder wall template to lock the rotating locking knob 13.

[0031] The laser rangefinder 14 with built-in alarm function can accurately set the error control range, and automatically sound an alarm when the range is exceeded, thereby minimizing human errors. The manually adjustable rotating platform 10 is provided with a manual rotating knob 12 and a rotating locking knob 13, which can perform one-time fixed-point measurement and setting for the support of the cylinder wall formwork in the same area, solving the drawbacks of repeated measurement and setting with a box ruler in the past, saving time, reducing the labor intensity of workers, and improving construction efficiency. It has a strong value for promotion and application.

[0032] like Figure 4As shown, a precise measurement and control device for the construction concentricity of the wall of a heat absorbing tower in a tower-type solar thermal project is used for centering with a laser plumb line 16 fixed at the center of the bottom of the heat absorbing tower. When the visible laser 17 emitted by the laser plumb line 16 passes through the through hole 7 of the sliding adjustable base 2 and hits the center of the rotating shaft 11, the centering of the present invention 18 and the laser plumb line 16 is completed.

[0033] A construction method for accurately measuring and controlling the concentricity of a heat absorbing tower wall of a tower-type solar thermal project, comprising the following steps:

[0034] S1, slide the adjustable base 2 to allow the visible laser 17 emitted by the laser plumb meter 16 to pass through the through hole 7.

[0035] The length of the sliding adjustable base 2 is 5-10 mm greater than the length of the standard section frame 1 of the construction elevator, which facilitates the sliding adjustable base 2 to slide freely in a fixed direction on the standard section frame 1 of the construction elevator, and quickly align the visible laser 17 emitted by the laser plumb line 16, so that the visible laser 17 emitted by the laser plumb line 16 passes through the through hole 7.

After the adjustment is completed, tighten the fixing screw 4 to complete the alignment and leveling work of the present invention 18 relative to the laser plumb line 16.

[0038] S3, after rotating the laser rangefinder 14, the laser 15 emitted by the laser rangefinder 14 is directed to the support position of the cylinder wall template, the template is adjusted to reach the designed radius and the laser rangefinder 14 no longer alarms.

[0039] During surveying and designing, the operator turns on the power of the laser rangefinder 14 and sets the radius and error range. After the setting is completed, the manual rotating knob 12 is turned to rotate the manually adjustable rotating platform 10 and the laser rangefinder 14 fixed thereon at the same time. The laser 15 emitted by the laser rangefinder 14 is directed to the support position of the cylinder wall template. The rotary locking knob 13 is locked and the corresponding cylinder wall template is adjusted until the laser rangefinder 14 no longer alarms, that is, the support of this section of the cylinder wall template is completed. Subsequently, the rotary locking knob 13 is loosened and the manual knob 12 is turned to make the laser 15 emitted by the laser rangefinder 14 be directed to the next section of the cylinder wall template. This is repeated until the support of the template at the same elevation is completed, and then the present invention 18 is used for re-inspection.
