Concrete meaning in the present invention.
As shown in fig.1, the installation measuring method of the inclined-plane basis mixing machine roller seat of the embodiment of the present invention, including:
Material set-up procedure, seat slurry parallels setting up procedure, slip gauge installation measurement process and roller seat installation four steps of measurement process.
Material set-up procedure:Make the slip gauge for meeting design requirement, seat slurry parallels.
Specifically, material set-up procedure includes:Slip gauge prepares peaceful parallels and prepares two processes.First, according to equipment
Design drawing determines basic top surface inclination angle, and a suitable slip gauge is made according to the angle of inclination of basic top surface.Meanwhile to protect
The precision of card slip gauge processing can be used wire cutting technology and carry out slip gauge making.Then, it is suitable to be selected according to design requirement
Material carries out the making of plain cushion iron, and a number of nut or flat shim are set on the side of plain cushion iron, to ensure plain cushion iron
Stability during subsequent installation.
In the present embodiment, the specification of slip gauge is 100mm × 200mm, and making material is Q235B, and plain cushion iron is a rectangle
Steel plate, is respectively welded that there are one M10 nuts on three sides of rectangular steel plates.
Seat slurry parallels setting up procedure:It determines the position of the seat slurry parallels, the seat is carried out using fluid grouting method
Starch the installation of parallels.
Specifically, parallels is configured using fluid grouting method, first, the hole setting of seat slurry is carried out according to design requirement,
And suitable grouting material is selected to be in the milk, to form firm seat pulp layer in Equipment Foundations.Then, existed using drilling equipment
Several holes are bored, and be implanted into screw rod in each hole in Equipment Foundations top surface, seat slurry hole periphery, are set on parallels side in order to wear
Nut or flat shim, parallels is prevented to be present in pulp layer and is slided, the fastness and stabilization set in pulp layer so that parallels is ensured to be present
Property.Meanwhile in order to facilitate adjustment of the later stage to parallels height, it is screwed into a nut in advance in the upper end of every screw rod, on the one hand has
The nut prevented on parallels side of effect prolongs screw rod and slides up and down;On the other hand tune of the later stage to parallels height is greatly facilitated
It is whole.Finally, parallels is placed in present pulp layer, and nut thereon is arranged on corresponding screw rod.
In the present embodiment, the specification in seat slurry hole is 150mm × 200mm × 50mm, more than grouting material use intensity grade C60
High strength and no shrinting fluid grouting material, with ensure formed seat pulp layer fastness and stability.The equipment base on seat pulp layer periphery
Plinth top surface is drilled with corresponding 3 nuts set with three side of plain cushion iron, a diameter of 6mm, the hole that depth is 50mm, in each hole
The M6 screw rods that length is 150mm are implanted with, on the one hand the effective slip placed parallels and be present in pulp layer, ensure that the stabilization of connection
Property;On the other hand adjustment of the later stage to parallels height is greatly facilitated.
Slip gauge installs measurement process:The slip gauge is arranged at the top of the seat slurry parallels, using described in level measurement
The levelness of slip gauge top surface, theodolite determine the position of the slip gauge, and spirit level measures the absolute altitude of the slip gauge.
Specifically, after parallels is provided with, slip gauge is placed at the top of plain cushion iron, puts survey using level meter first
Gauge block advises the levelness of top surface, and passes through the nut on the screw rod that the Equipment Foundations top on adjustment seat pulp layer periphery is adjusted to be implanted into up and down
It drives the nut set on parallels side or the flat shim to move up and down, so that slip gauge is moved with parallels, and then reaches adjustment
The purpose of slip gauge top surface levelness, makes slip gauge be finally reached horizontality.Then on the basis of foundation bolt center line, warp is used
Latitude instrument positioning slip gauge position, and push slip gauge that slip gauge center line is made to be overlapped with foundation bolt center line.Finally surveyed using spirit level
Gauge block advises top surface absolute altitude.
It should be noted that the adjustment and survey of seat slurry parallels are for measuring to a series of adjustment that slip gauge carries out
Amount makes seat slurry parallels meet design requirement namely if the absolute altitude for measuring slip gauge meets design requirement, then seat slurry plain cushion iron top
The absolute altitude in face also complies with design requirement.
Roller seat installs measurement process:Roller seat is set, the slip gauge is placed in the carrying roller top surface, is surveyed using spirit level
Measure carrying roller top surface absolute altitude, theodolite and dipstick metering inspection measure numerical value between roller seat, and adjust the carrying roller horizontal stroke,
Longitudinal center.
Specifically, after by slip gauge top surface absolute altitude, Level-adjusting qualification, block is taken away from seat slurry parallels upper end first
Rule, and roller seat is lifted into seat slurry parallels upper end;Then slip gauge is placed in carrying roller top surface, in order to which spirit level is used to measure support
Roller top surface scale;Finally roller seat is checked using theodolite and ruler, on the basis of mixing machine transverse and longitudinal center line into
The measurement of the numerical value such as distance between the adjacent and opposite roller seat of row, and adjust the horizontal stroke of carrying roller, longitudinal center.
It should be noted that if the height for measuring carrying roller top surface is unsatisfactory for design requirement, can be held in the palm by adjusting being arranged on
The height of seat slurry parallels below roller makes the height of roller seat change, until the calibrated altitude being pre-designed is reached.
Obviously it can obtain, be made in the installation measuring method of inclined-plane basis mixing machine roller seat provided by the invention
Slip gauge is simple for production, and measuring instrument is conventional instrument, simple operation, cheap, is installed, is measured using this method
Inclined-plane basis mixing machine roller seat can effectively shorten installation period, improve installation accuracy, reduce cost.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art
God and range.In this way, if these modifications and changes of the present invention belongs to the range of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to include these modifications and variations.
