Description
Technical field
The present invention relates to a kind of mechanical device, more particularly to a kind of mechanical device for modular trestle bearing.
Background technology
Modular trestle is that rubber conveyer and external force structure are integrated, and repeats the assembled new trestle of dismounting
Form.It is the attachment structure that multispan is formed by the assembled connection composition one of bolt between individual module.Traditional trestle bearing is held
Load vertical force simultaneously can be rotated, slided, but be installed, dismounting inconvenience.
The content of the invention
In order to make up the deficiencies in the prior art, solve the problems, such as modular trestle bearing installation, dismantle it is inconvenient, there is provided one
Kind trestle bearing.
The technical solution adopted for the present invention to solve the technical problems is：
Trestle bearing, mainly by bracket, twisted axis, polytetrafluoroethylene (PTFE) sliding layer, sleeve, guide plate, pillar, stainless steel pad
Plate, set screw, peep hole door and positioning boss composition, the sleeve described in it is pipe, sleeve pipe upper end closed, in sleeve
Top sets four screwed holes, and sleeve top center sets hanger, circular hole is set in the middle part of hanger, and hanger is connected by twisted axis and held in the palm
Frame, bracket are inverted concave, and middle part sets circular hole, and top sets multiple circular holes, and bracket sets hanger concavo-convex with sleeve top center
Connection, pallet top are bolted trestle crossbeam channel-section steel；Barrel bore top down connects stainless billet, stainless steel pad
Plate is circle, stainless billet bottom connection polytetrafluoroethylene (PTFE) sliding layer top, and polytetrafluoroethylene (PTFE) sliding layer is truncated cone-shaped, poly- four
PVF sliding layer bottom connection pillar top, pillar are pipe, pillar upper end closed, and pillar upper end outer rim sets convex
Platform, positioning boss are annular, are connected in positioning boss outside polytetrafluoroethylene (PTFE) sliding layer, four spiral shells that sleeve middle and upper part is set
Four set screws are connected in pit respectively, connect the cylindrical top of pillar at the top of four set screws, lower cartridge is symmetrical arranged
Guide plate, guide plate are rectangle, and guide plate both ends are connected with sleeve diameter, and two guide plate flues are suitable for reading small, lower mouth
Greatly, distance suitable for reading is equal to pillar external diameter, and upper cartridge sets cubic peep hole, peep hole door is set at peep hole.
The beneficial effects of the invention are as follows：
1st, bracket 1 of the present invention is connected by bolt with trestle crossbeam channel-section steel, and bracket 1 undertakes trestle crossbeam channel-section steel vertical load
And horizontal loading, hinge 2 can rotate, and can discharge moment of flexure.
2nd, polytetrafluoroethylene (PTFE) sliding layer 3 is set inside sleeve 4, polytetrafluoroethylene (PTFE) has that coefficient of friction is small, and with good
Weatherability, service life length, and guide plate 5 are used cooperatively, and realize the horizontal distortion requirement of trestle.Sleeve 4 is not only limited deformation
Position, while the polytetrafluoroethylene (PTFE) sliding layer of inside is played a protective role.
3rd, set screw 8 can be adjusted to bearing, be accurately positioned, can when without the concern for horizontal displacement
Screens is carried out with set screw, realizes the requirement of fixed-hinged support.
4th, present invention installation, convenient disassembly, construction is simple, can prevent the landing of the trestle under moderate finite deformation, safe,
Good to environmental condition adaptability, cost economic is reasonable.
