Abstract
The invention provides a sliding shoe for sliding of a steel truss. The sliding shoe comprises a positioning plate, a rail and a plurality of parallel round rollers same in specification. The positioning plate is horizontally distributed. The longitudinal section of the rail is in an H shape. The rail is composed of two parallel vertical wing plates and a horizontal web plate fixedly arranged between the two wing plates, so that a groove used for containing the rollers is formed in the upper portion of the rail. The outer diameter of the rollers is larger than the depth of the groove, and the length of the rollers is smaller than the width of the groove. The rail is arranged on the positioning plate through the lower sides of the two wing plates. The rollers are arranged in the groove and in rolling fit with the groove. The axis of the rollers is perpendicular to the two wing plates. By the adoption of the sliding shoe, the steel truss slides by means of rolling of the rollers, construction cost is reduced, and construction difficulty is reduced.
Description
Technical field
The present invention relates to a kind of Elements of Space Grid Truss sliding piston shoes.
Background technology
Steel grid structure has obtained more application in engineering, and the construction method of steel grid structure has 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 fixed on the bearing of Elements of Space Grid Truss by the bottom bar of Elements of Space Grid Truss, 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 jointly at the enterprising line slip of sliding rail.
The heavier-weight of Elements of Space Grid Truss, in addition being sliding friction between bearing and sliding rail, so, the frictional force produced during bearing sliding is bigger, just need to can make Elements of Space Grid Truss sliding with the hitching machinery of relatively high power, cause that Elements of Space Grid Truss itself is vulnerable to damage, construction cost is higher, difficulty of construction strengthens.
Summary of the invention
The technical problem to be solved is to provide a kind of Elements of Space Grid Truss sliding piston shoes, uses these piston shoes, can make Elements of Space Grid Truss sliding by the rolling of cylinder so that construction cost declines, difficulty of construction reduces.
For solving above-mentioned technical problem, the invention provides a kind of Elements of Space Grid Truss sliding piston shoes, it includes location-plate, track, some is parallel to each other and circular drum that specification is identical, and location-plate is horizontally disposed；
The vertical sectional shape of track is H-shaped, track by two wing plates being parallel to each other and vertically arrange, one be fixedly arranged between two wing plates 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 and coordinates, and 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 of the present invention are all referred to as these piston shoes.
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 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, using these piston shoes, its advantage is:
1, in the slipping of Elements of Space Grid Truss, cylinder is to roll along groove length direction in groove, and so, the damage caused because of friction between Elements of Space Grid Truss and cylinder effectively reduces；
2, can effectively reduce pull strength during hitching machinery traction Elements of Space Grid Truss sliding, reduce equipment investment and the sliding cost of Elements of Space Grid Truss of hitching machinery, 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, difficulty of construction reduces.
For making these piston shoes reach more preferable using effect, the preferred version of the present invention is as follows: the upper side of described web, 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, the physical dimension of some part can be recovered, also there is 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, the effect of lubricant can be played, when cylinder roll on web, Elements of Space Grid Truss by the rolling slip of cylinder time, between cylinder and web, Elements of Space Grid Truss, produced frictional force reduces further, so, the damage caused because of friction between Elements of Space Grid Truss and cylinder reduces further, and pull strength during hitching machinery traction Elements of Space Grid Truss sliding reduces further, and 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, and location-plate 1 is horizontally disposed.
The vertical sectional shape of track 2 is H-shaped, track 2 by two wing plate 2b being parallel to each other and vertically arrange, one be fixedly arranged between two wing plate 2b and horizontally disposed web 2a is constituted so that a groove 2c being used for accommodating eight cylinders 3 is formed at the top of track 2.
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 rolls with groove 2c and coordinates, and the axis of cylinder 3 and two wing plate 2b are perpendicular.
The upper side of described web 2a, cylinder 3 cylinder on all have molybdenum bisuphide coating (molybdenum bisuphide coating not shown in Fig. 1).
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, and 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 (Elements of Space Grid Truss not shown in Fig. 2), and the bottom surface of bearing 4a is plane；The radial direction left and right sides of cross bar 4 is respectively arranged with a horizontal-extending traction otic placode 4b, traction otic placode 4b and is used for being connected with pull rope and hitching machinery (pull rope and hitching machinery not shown in Fig. 2), 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 positioning baffle 4c extended straight down, and 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.
