Specific installation technology of mining machinery equipment
(2) alignment.
Mountain mining machinery equipment in the process of installation directly affects the quality of the final equipment installation.
Alignment requires that the vertical and horizontal centers and the base lines are defined and aligned between them.
In addition to this basic requirement, the installation personnel should strictly follow the installation plan designed in advance to ensure that the details of the installation meet the requirements.
Only when the center is consistent can the correct work be done accurately.
Once the two positions are not the case.
In time to find the cause of the problem, and to adjust.
In the process of subsidence of mining machinery equipment, the staff should pay attention to the setting standard of the whole unit, and at the same time adjust and configure the settlement observation point.
In this link, the determination of reference points is very important, and four of them are generally arranged to improve the accuracy of the position.
In this way, it is more convenient to check the settlement state of each datum, and the accuracy of the position of the mechanical fixed point will be higher than the figure.
Of course, in practice, due to improper operation or not fully considered the conditions of alignment lead to the setting of mechanical fixed point does not conform to the provisions of the situation occurs, then can use graphics to complete the alignment of mining machinery equipment.
Alignment of plates and reference points is very important,
(3) mechanical positioning and adjustment.
Mechanical positioning belongs to the key link of quality control for the installation of mining machinery equipment.
In order to meet the requirements, when the mechanical equipment is hoisted by the bridge crane, it is necessary to set up the center table board in time to complete the hook work of the datum line.
Specific operation to ensure that the state of tension is stable, while the installation personnel also want to control the level and tilt of the hanging span, usually requires that the span does not exceed 40 meters, once exceeded to timely adjustment.
In view of the elevation of mining machinery equipment to adopt the correct method to adjust, the elevation of the quantity.
General reference point location to determine in practice depends on the precision instruments, through the instrument and then determine the benchmark for the higher precision, conforms to the requirements, to ensure the quality of mining machinery equipment installation 3. Sure you want to combine working face the levelness of the mechanical equipment adjustment and accurate measurement mountain, because moreover is mine machinery equipment installation involves all aspects of content, especially with the work surface directly, therefore should adopt different precision level to complete mechanical level adjustment.
Inspection and correct connection of mining machinery equipment
(1) select the correct inspection method.
The inspection method of mining machinery equipment should be accurate and scientific, and the specific standards should be referred to in the specific application.
When checking, the staff can use the design instructions and requirements to avoid errors.
In the measurement stage, it is mainly carried out for the fixed position, with the purpose of obtaining the data of the fixed position and the corresponding surface and external dimensions. Of course, the inspection and measurement of the horizontal degree and plumb degree of the fixed position cannot be ignored.
In practice, especially in the mine operation process will be applied to a lot of large facilities and equipment, this kind of equipment should be preloaded before formal use, to ensure that the quality of the equipment will not be too large and the problem of operation errors.
(2) select the correct connection method.
Use the right connections
Methods it is very necessary to install mining machinery equipment. Some equipment needs to be kept in normal condition for a long time.
In this stage, it is necessary to apply the anchor bolt to fix the mechanical equipment on the foundation through this equipment, so as to prevent the problem of displacement and overturning of the mechanical equipment, effectively reduce the vibration, and reduce the damage to the mechanical equipment in the process of use.
During this process, the appropriate anchor bolt is selected and tested before it is put into use so that it can perform its expected function.
The installation of the anchor bolt needs to refer to the specific plan, because in the mine machinery equipment is a lot of large equipment, the quality is large, when the installation to use a lot of facilities to complete.
For this reason, the anchor bolt should be fixed to prevent disassembly or reinstallation during operation.
