Description
Technical field
This utility model relates to a kind of Elements of Space Grid Truss sliding piston shoes.
Background technology
Steel grid structure has obtained more application in engineering, the construction method of steel grid structure have accumulative sliding technique,
Segmental hoisting method, Integral Lifting etc..
Accumulative sliding technique is constructed, and needs to arrange sliding rail to Elements of Space Grid Truss.Before Elements of Space Grid Truss sliding, be by the bottom of Elements of Space Grid Truss
Cross bar is fixed on the bearing of Elements of Space Grid Truss, and the bottom surface of bearing is plane and contacts with sliding rail, is drawn by hitching machinery, makes
Elements of Space Grid Truss and bearing are jointly at the enterprising line slip of sliding rail.
The heavier-weight of Elements of Space Grid Truss, in addition for sliding friction, so, generation during bearing sliding between bearing and sliding rail
Frictional force relatively big, just need to can make Elements of Space Grid Truss sliding with the hitching machinery of relatively high power, cause Elements of Space Grid Truss itself be vulnerable to damage,
Construction cost is higher, difficulty of construction strengthens.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of Elements of Space Grid Truss sliding piston shoes, uses these piston shoes, can
Rolling by cylinder makes Elements of Space Grid Truss sliding so that construction cost declines, difficulty of construction reduces.
For solving above-mentioned technical problem, this utility model provides a kind of Elements of Space Grid Truss sliding piston shoes, it include location-plate,
Track, some being parallel to each other and circular drum that specification is identical, location-plate is horizontally disposed；
The vertical sectional shape of track is H-shaped, track be parallel to each other by two and vertically arrange wing plate, one be fixedly arranged on two
Between individual wing plate and horizontally disposed web is constituted so that if a groove being used for accommodating dry drum is formed at the top of track；
The external diameter of cylinder is more than the degree of depth of groove, and the length of cylinder is less than the width of groove；
Track is arranged on location-plate by the downside of two wing plates, and cylinder is placed in groove, and cylinder rolls with groove joins
Closing, the axis of cylinder and two wing plates are perpendicular.
For the sake of simple declaration problem, below Elements of Space Grid Truss sliding piston shoes described in the utility model are all referred to as this cunning
Boots.
During use, if Elements of Space Grid Truss is placed on dry drum by its bearing, draw Elements of Space Grid Truss by hitching machinery, by rolling
Cylinder rolling in groove, so that it may make Elements of Space Grid Truss smoothly, nondestructively carry out sliding.
It is known that the frictional force that the frictional force produced when object rolls produces when sliding much smaller than it.Therefore, use
These piston shoes, its advantage is:
1, in the slipping of Elements of Space Grid Truss, cylinder be in groove along groove length direction roll, so, Elements of Space Grid Truss with
The damage caused because of friction between cylinder effectively reduces；
2, can effectively reduce hitching machinery traction Elements of Space Grid Truss sliding time pull strength, reduce hitching machinery equipment investment and
The sliding cost of Elements of Space Grid Truss, energy consumption declines, improves the efficiency of construction of Elements of Space Grid Truss, and economic benefit is obvious.
In sum, use these piston shoes, Elements of Space Grid Truss sliding can be made by the rolling of cylinder so that construction cost declines, executes
Work difficulty reduces.
For making these piston shoes reach more preferable using effect, preferred version of the present utility model is as follows: the upside of described web
Face, cylinder cylinder on all have molybdenum bisuphide coating.
It is known that the coefficient of friction of molybdenum bisuphide is relatively low, there is the performance that lubricant is filled up, can recover some zero
The physical dimension of part, also has the characteristic such as protection against the tide, waterproof, alkali prevention, acid-proof, can service life of extension device.
The setting of molybdenum bisuphide coating, can play the effect of lubricant, when cylinder roll on web, Elements of Space Grid Truss is by rolling
During the rolling slip of cylinder, between cylinder and web, Elements of Space Grid Truss, produced frictional force reduces further, so, and Elements of Space Grid Truss and rolling
The damage caused because of friction between Tong reduces further, and pull strength during hitching machinery traction Elements of Space Grid Truss sliding subtracts further
Little, energy consumption declines further.
Accompanying drawing explanation
Fig. 1 is the structural representation of these piston shoes.
Fig. 2 is the use state reference map of these piston shoes.
Detailed description of the invention
See Fig. 1:
It includes location-plate 1, the circular drum 3 that 2, eight, track is parallel to each other and specification is identical, the horizontal cloth of location-plate 1
Put.
The vertical sectional shape of track 2 is H-shaped, track 2 be parallel to each other by two and vertically arrange wing plate 2b, one fixed
Between two wing plate 2b and horizontally disposed web 2a is constituted so that the top of track 2 forms one and is used for accommodating eight rollings
The groove 2c of cylinder 3.
The external diameter of cylinder 3 degree of depth more than groove 2c, the length of cylinder 3 width less than groove 2c.
Track 2 is arranged on location-plate 1 by the downside of two wing plate 2b, and cylinder 3 is placed in groove 2c, and cylinder 3 is with recessed
It is perpendicular that groove 2c rolls cooperation, the axis of cylinder 3 and two wing plate 2b.
The upper side of described web 2a, cylinder 3 cylinder on all have molybdenum bisuphide coating (molybdenum bisuphide not shown in Fig. 1
Coating).
The width of location-plate 1 is 55mm.Track 2 uses I-steel, turns over and turn 90 degrees；The degree of depth of groove 2c is 40mm,
The width of groove 2c is 200mm.Cylinder 3 uses hollow circular-tube, and its external diameter is 60mm, pipe thickness is 10mm, a length of
190mm。
Seeing Fig. 2, the structure of existing Elements of Space Grid Truss is: the bottom circular cross bar 4 of Elements of Space Grid Truss is fixed on the bearing 4a of Elements of Space Grid Truss
Upper (Elements of Space Grid Truss not shown in Fig. 2), the bottom surface of bearing 4a is plane；The radial direction left and right sides of cross bar 4 be respectively arranged with one horizontal-extending
Traction otic placode 4b, traction otic placode 4b be used for being connected (pull rope and traction machine not shown in Fig. 2 with pull rope and hitching machinery
Tool), and more convenient when drawing Elements of Space Grid Truss；The left and right sides of the bottom surface of bearing 4a is respectively arranged with a location extended straight down
Baffle plate 4c, so, during traction Elements of Space Grid Truss, positioning baffle 4c can be prevented effectively from the sliding trajectory of Elements of Space Grid Truss and produce bigger
Skew.
Seeing Fig. 2, the occupation mode of these piston shoes is:
1, lay these piston shoes and position；
2, the bearing 4a load carrying Elements of Space Grid Truss and cross bar 4 is placed on eight cylinders 3 of these piston shoes；
3, start hitching machinery, along the length direction of groove 2c, Elements of Space Grid Truss can be carried out sliding operation.
