轨道、滑线、轨道梁安装要求


 

1) check whether the steel structure of the factory building conforms to the installation conditions (i.e. the overall settlement, or whether the deflection is fixed). In accordance with the installation conditions in order to enter the construction, otherwise the owner should be informed of the rectification to the installation requirements.

2) check whether the position of each point is in conformity with the design. If the match is entered, the owner does not agree to inform the owner to meet the advance.

3) the required track for site installation is processed in the factory to the design requirements. The packing is transported to the owner's construction site.

4) with the level and scale, the horizontal elevation of each point is measured, the data is unified, the high and low error is calculated, and the high and low level error is less than 10mm. The vertical horizontal error is less than 10mm, the linear horizontal error is less than 10mm, and the span error is less than 10mm. If we fail to meet the above requirements, we need to adjust the lifting point device until we reach the standard, so we can carry out the next operation.

5) adjust track lifting, lifting point center line draw on one side, to pull out the center mounted crane with tape or rangefinder span, requirements on the other side hanging points, the error is less than 5mm, marked by the whole length of the center line to walk out and correction.

6) in the above data right after confirmation by the crane or hoist hanging on the hanging point above the installation workers auxiliary to the scaffolding, safety measures, the suspension track slowly lifted, the best one rail across the 3 lifting points, hand pulling hoist slowly tighten, positioning, connection to the hanging point at contact, with level, the level of scale, hammer, adjust the levelness and verticality, straightness, the center position shall meet the design requirements, preliminary fixed, complete the whole walking distance of one side of the installation in accordance with the above steps, the other side were corrected at the same time span, lifting, or on both sides simultaneously, multi pivot track at the same time draw the 3 rail base line span center track in place after the initial fixed, the entire track after lifting adjustment of the data in the data, to meet the design requirements of the ultimate fixed.

7) track connection. According to the design requirements, the connection above the track should be connected with the fishtail plate with the same specifications, and the length is not less than 300mm. This connection can be partly connected to the ground, and some parts are connected in the air to facilitate hoisting and transportation. All suspension and multi - fulcrum tracks are completed according to the above requirements.

8) bridge crane rail installation, check the track bearing rail beam level, to meet the requirements, draw the unilateral center line, and then pull out the tape to span, the error is less than 10mm, the other side of the center should not be partial to the bearing rail beam center 10mm data track hanging in the allowable range, the deviation is too large notify the owner to meet the requirements after rectification, lifting the track, with plate and bolt to rail fixed to the bearing rail beam.

9) adjust the track span and the level.

10) + 10mm gauge deviation; rail joint gap is less than or equal to 2mm; the track center line and the bearing rail beam centerline deviation less than 10mm.

11) power sliding line installation in which a bearing rail beam (near the crane electrical cabinet side) welding slide wire rack, the interval distance of 1-1.5 meters, the end of the tension device (monopole can not slide wire tensioning device), and the same level of track, stent length multipole slide wire 150-250mm, single slide wire rack 450-540mm, pay attention to crane bottom and not to interfere trail maintenance. Then the slide line hanger is installed, the slide line is installed, the tension and the straightness are adjusted with the pull - in, the error is not more than 10mm.

12) power line owners provide power supply and power supply for installation from the cabinet to the end of the crane slide wire installation. In the process of installation, the owner will send the site representative to be responsible for the coordination, supervision and other work.

13) the owner provides safe and easy access to the installation site.

The owner provides the required lighting and power supply at the installation site, providing the installation storage area and ensuring adequate safety hoisting space.

Before the installation, the manufacturer has the obligation to assist the owner to accept the rail beam installed. If it does not meet the requirements, the owner should be required to rectify the construction party. The crane is installed on the existing track beam, and the manufacturer is not responsible for the safety of the load-bearing beam and the subsidiary steel structure of the purchaser.

The owner should ensure that the installation accuracy is in line with the installation requirements of the crane. The height difference of the joint of the bearing beam is not more than 6mm straightness, positive and negative 10mm

14.) after the installation is completed, the manufacturer will carry out the commissioning and acceptance according to the relevant national standards, and submit the inspection application to the special inspection institute, and the owner is ready to provide the test weight for inspection.
