The light tower is a high-rise building, generally with a height of more than 190 m. The difference between the light tower and the ordinary chimney of a thermal power plant is that the light tower is a comprehensive structure integrating structure, equipment, pipeline, heat absorption, elevator, etc. The construction difficulty is great.

Most of the existing technology construction of mechanisms and equipment is assisted by external tower cranes for hoisting. The special power transfer equipment needs to be purchased to transfer the heat absorber to the position below the heat absorber steel frame.

[0038] The method of using and working principle of the heat absorber sliding device: I. Installation of the heat absorber sliding track 1 1. Inspection and confirmation conditions before track installation: 1. The sliding track foundation has been completed and passed the acceptance check.

[0039] 2. The track foundation line has been completed and passed the acceptance check.

[0040] 3. The quantity of track materials and accessory equipment is checked, and the quality is accepted.

[0041] 4. The track bearing load calculation book, the track foundation and the track are designed according to the requirements of the heat absorber sliding, and the foundation is accepted by the general contractor and other units when it is handed over to the user, so there is no need to conduct a load test on the track by adding weights on site.

[0042] 2. Installation and standards of the heat absorber sliding track 1 1) Track composition: The heat absorber sliding track is composed of two parallel sliding rails, and the number of sliding rails for each line is 19, with a length of 5.4m for each rail, and a total length of 102.9m for a single track.

[0043] 2) Track installation method: The track is directly laid on the surface of the concrete foundation using a tower crane, and after alignment and acceptance, each track is fixed to the foundation using four clamps and bolts.

[0044] 3) Sliding track parameter standards, Number of sliding rails for each line Length of each rail = 5.4m: 19 Sliding track spacing: 16098 ± 1.5mm Maximum transverse slope: ±0.1% Maximum longitudinal slope: ±0.5% Maximum longitudinal gap between two sliding rails: 10mm Maximum plane deviation of two sliding rails: 1mm Maximum vertical gap between two sliding rails: 1mm The track foundation is designed according to the load during the sliding process of the heat absorber, and the load of the track is not checked on site. Only after the size of the foundation is accepted, the track is installed. The size of the track is checked according to the parameters above.

[0045] II. Installation of sliding shoes The bottom floating plate of the sliding device is installed in the sliding rail. The bottom floating plate is hoisted by the main oil top until the oil top flange is tightly attached to the lower surface flange of the heat absorber ring beam. Adjust the sliding device so that the oil top flange is directly opposite the flange of the support ring beam bottom plate. Use M30x140mm bolts to connect and finally tighten.

[0046] III. Sliding process of heat absorber sliding device After checking that the installation position of the sliding device is correct, the central main jack 22 can be jacked up until it contacts the flange of the support ring beam 4. The four sliding lifting devices are operated by one control system to ensure that the hydraulic lifting devices act simultaneously to lift the heat absorber horizontally.

[0047] 1. Start the lifting device to lift the support ring beam and the heat absorber together. The load of the hydraulic lifting device is increased by 20% until it reaches 100% load. Carefully check the deformation of the track concrete foundation, track, and support ring beam, and the bolt connection state of the ring beam and the lifting device, and make relevant records; 2. Start the four hydraulic lifting devices to lift the support ring beam and the heat absorber by 200mm, then start the sliding device, and each time the sliding distance is 600mm. During the sliding process, the computer control system is used to monitor whether the stroke and load of each sliding device are consistent. The load of the sliding device should be basically consistent within one stroke, and the deviation should not be more than 5%. After each sliding stroke is completed, the load and stroke of the sliding device are adjusted through the computer control system to ensure that the four sliding devices act synchronously. Repeat the above operation until the heat absorber is slid to the position directly below the tower.

[0048] IV. Related calculations during sliding 1. Sliding shoe calculation Calculation under the condition of maximum wind force 10m / s, heat absorber weight increase 10%, and center of gravity deviation 0.5m during sliding: 1) Heat absorber sliding geometric size 2) Wind force and braking force calculation A. Wind force calculation This heat absorber can be regarded as a cylinder composed of 16 polygons, with a wind receiving area of 21x35=735m2. The drag coefficient of this shape is 1.3. Assuming the maximum allowable wind speed is 10 meters / second, the wind force can be calculated by the following formula: The MSR (heat absorber) can be considered as a polyhedral cylinder with 16 faces. The windward area is approximately 21*35=735m2. The drag coefficient of this shape is 1.3 according to the table: Assuming the maximum allowable wind speed at the top of the tower is 10 m / s, the basic wind pressure is: PW=C2 / 16=6.25kgf / m2, so the total wind force of the maximum allowable wind speed is a safety factor of 1.5: H1,d=0.00625×1.3×735×1.5=9mT B. Braking force calculation The friction coefficient of the polyethylene sheet in the sliding track is 0.05. Assuming that the friction force is increased by a safety factor of 1.5 times, which is equivalent to a 10% increase in the weight of the heat absorber, the braking force is: H2,d=0.05×1.5×735×1786.4=134mT C. Total forces on overturning and eccentricity under the action of wind and braking force: H=H1,d+H2,d=9+134=143mT Horizontal moment: MT,d = 143 × 19.814 = 2833.4 m2T The increase in eccentricity under the action of this force is: e=MT,d / WT,d=2833.4 / 1786.4=1.5m, Changes in the stress distribution of the heat absorber after 1.5m eccentricity: Right vertical line redistribution coefficient: CD = 9864 / 16098 = 0.613 Upper horizontal line redistribution coefficient: BC = 8298 / 16098 = 0.515 Left longitudinal line redistribution coefficient: AB = 1-0.613 = 0.387 Lower lateral line redistribution coefficient: AD = 1-0.515 = 0.485 Force on each sliding shoe: RA = 0.387 × 0.485 × 1786.4 = 335.3 mT RB=0.387×0.515×1786.4=356.0mT RC=0.613×0.515×1786.4=564.0mT RD=0.613×0.485×1786.4=531.1mT The maximum force of the sliding shoe is 564mT, which is less than the rated load of the sliding shoe 600mT, and is qualified.

[0049] 2. The track foundation and track are designed according to the parameters related to the heat absorber slip. In this embodiment, the track does not need to be calculated. The track is only inspected and accepted according to the standard parameters after the foundation and track are completed.

[0050] V. Slippage process monitoring measures: 1. The computer control system monitors the stroke and load of the slipper to ensure that the four slipper move synchronously; 2. The verticality of the heat absorber body is monitored by the theodolite in real time during the slippage process; 3. The real-time subsidence of the slippage foundation is measured by the high-precision level gauge during the slippage process to ensure the slippage safety, and if the slippage exceeds the safety standard, the relevant design party should be reported, and the actual situation on site should be evaluated.

[0051] 4. The wind speed on site is monitored in real time during the slippage process, and the slippage is stopped when the wind speed exceeds the standard requirement.
