Description
Technical field
This utility model belongs to construction steel structure field, particularly relates to a kind of trestle self-reset rolling stand apparatus.
Background technology
Roller bearing is a kind of basic support style in building structure, and its preferable power transmission pattern is only to transmit the vertical load from superstructure, discharges the stress produced by factors such as temperature, displacement, deformation.The form of roller bearing plays critical effect for the service behaviour of roller bearing.
Existing support style can be divided into two kinds substantially according to rolling form difference: a kind of multiaxial type roller bearing (slip) bearing being to be similar to bridge, this bearing roller bearing quantity is more, because the general environment in the open of trestle roller bearing uses, between roller bearing corrosion, roller bearing, between dust stratification and adjacent roller bearing, friction is unavoidable, and therefore roller bearing is restricted when linkage rolls；Additionally multiaxial type roller bearing typically requires that roller bearing structure cantilever span is relatively big, and this is unfavorable for supporting structure stress.Another roller bearing is for be placed on steel plate on multiple roller (roller is fixed in bottom), rely on the mobile release stress of steel plate, the cardinal principle of this kind of support style foundation is to reduce the steel plate contact area with supporting-point to reduce frictional force, so that steel plate moves, but steel plate can cause frictional force between the two to increase with the corrosion of roller, under temperature stress effect, iterative motion is relatively difficult.
Utility model content
This utility model is in order to solve weak point of the prior art, it is provided that a kind of processing cost is low, simple in construction, reasonable stress, easy for installation, release stress trestle self-reset rolling stand apparatus thoroughly.
For solving above-mentioned technical problem, this utility model adopts the following technical scheme that a kind of trestle self-reset rolling stand apparatus, it includes bearing top board and the base-plate being correspondingly arranged up and down, it is provided with roller bearing between bearing top board and base-plate, the position being positioned at roller bearing radially opposite sides on base-plate is provided with slide damper, on slide damper, roller bearing corresponding position is provided with camber line slideway, be provided with horizontal slide on base-plate with roller bearing corresponding position, described camber line slideway is connected formation roller bearing slideway with horizontal slide；The axial both sides being positioned at roller bearing on bearing top board have been respectively fixedly connected with upper vertical plate, base-plate is positioned at the axial both sides of roller bearing and has been respectively fixedly connected with the central axis corresponding position of lower riser, upper vertical plate and lower riser and roller bearing and all offers long lumbar hole；It is equipped with pivot pin at the central axis of roller bearing, and the two ends of pivot pin are each passed through upper vertical plate and the long lumbar hole of lower riser.
Circumferentially arranged with slide-and-guide groove on described roller bearing, horizontal slide is provided with and the slide-and-guide bar of described slide-and-guide slot fit.
The both sides that described bearing top board is positioned at roller bearing are respectively arranged with dust-proof guard.
Described dust-proof guard is articulated and connected with described bearing top board by hinge.
The beneficial effects of the utility model:
Roll on the roller bearing of the present utility model roller bearing slideway between bearing top board and base-plate, the stress that release trestle produces due to variations in temperature, displacement etc..During use, if trestle deformation is relatively big, roller bearing will slide on camber line slideway, forces trestle by restoring force, it is to avoid trestle exceedes serviceability limit state and affects the use of equipment on trestle；Additionally can also adjust ultimate range and the default maximum restoring force being subject to that slide damper distance and long lumbar hole size can be slided with control trestle as required.Circumferentially arranged with slide-and-guide groove on roller bearing, horizontal slide being provided with and the slide-and-guide bar of described slide-and-guide slot fit, slide-and-guide bar can play the guide effect to roller bearing with coordinating of slide-and-guide groove, it is to avoid axial dipole field occurs when roller bearing rolls.Bearing top board is positioned at the axial both sides of roller bearing and is respectively arranged with dust-proof guard, can enter slideway with blocks dust.Dust-proof guard is articulated and connected with described bearing top board by hinge, to realize the folding of dust-proof guard.
This utility model processing and fabricating is easy, and cost is relatively low, simple in construction, and release stress is complete, and machining accuracy is high, and error is little, it is adaptable to the various steel trestles such as coal, oil and foodstuffs, electric power, metallurgy, warehouse logistics.
