Below in conjunction with Fig. 2 to Fig. 8 describe in detail of the present utility model for jack construction can horizontal sliding
Device.
Embodiment one
One can horizontal sliding device, for jack 1 jacking and unloading construction in, horizontal including a pair
The top board 11 be arrangeding in parallel and base plate 12；It is convex stupefied that top board 11 bottom surface is provided with " T-shaped ", base plate 12 end face
Being provided with the stupefied chute that match convex with " T-shaped ", top board 1 can pass through T-shaped " convex stupefied along chute phase
Base plate 12 is slided, between convex stupefied and chute and contactless；A connection piece (not shown), connector bag
Including some groups of roller bearings 31 and the roller support 32 being correspondingly arranged on base plate 12, roller bearing 31 is propped up by roller bearing
Frame 32 is located between top board 11 and base plate 12, and top board 11 can be relative to base plate 12 by roller bearing 31
Horizontal sliding；One steel bushing 40, steel bushing 40 is fixed on the lower end of base plate 12；And a stopping means
50, the detachable end being connected to base plate 12 of stopping means 50.
Specifically, this can horizontal sliding device, including top board 11, base plate 12, top board 11 and base plate
Roller bearing 31 between 12, the steel bushing 40 being arranged at base plate 12 lower surface and stopping means 50, top board
Leave a gap between 11 and base plate 12, say, that the bottom surface of top board 11 and the end face of base plate 12 it
Between leave a gap.Steel bushing 40 presses the model customization of jack 1, to be inserted in the top of jack 1；
Stopping means 50 is for limiting the distance of top board 11 horizontal sliding and carrying out the most spacing to top board 11；
Roller bearing 31 is for being transferred to base plate 12 by the vertical load of top board 11, simultaneously by top board 11 and base plate 12
Separating, it is to avoid the two straight surfaces brought into contact, top board 11 can opposed bottom 12 horizontal sliding by roller bearing 31.
The present embodiment can horizontal sliding device, can largely reduce in work progress because of by jacking thing 2
The tilting moment that horizontal displacement causes, it is to avoid the security incident that jack 1 topples and causes.And, this can
The convenient dismounting of horizontal sliding device assembles, can reduce stress raisers, it is to avoid set above jack 1
Put cushion block.It is additionally, this can directly be inserted in jack 1 top during the use of horizontal sliding device, easy and simple to handle,
Stablize safety, remarkable in economical benefits.
Especially, stopping means 50 includes that spacing steel plate 51 and gag lever post 52, spacing steel plate 51 vertically set
Being placed in the one or both ends of " T-shaped " chute, gag lever post 52 is arranged at intervals on spacing steel plate 51, limit
Axially paralleling of axial and " T-shaped " chute of position bar 52.For realizing limiting top board 11 horizontal sliding
Distance, detachable base plate 12 end that is fixedly mounted on of spacing steel plate 51, such as by bolt (not shown)
Connect.
Especially, the internal diameter of steel bushing 40 is slightly larger than the diameter on jack 1 top, in order to steel bushing 40
Shirk.It is to say, the internal diameter of steel bushing 40 is than the diameter big 2～3mm on jack 1 top, with side
Just the two directly shirks.The top of jack 1, top board it is directly sleeved in view of steel bushing 40
The vertical load of 11 is directly delivered to base plate 12 by roller bearing 31, then by the sleeve 40 on base plate 12
It is delivered on jack 1, thus needs to strengthen steel bushing 40 and top board 11, the rigidity of base plate 12.
Therefore, being provided with ribbed stiffener 41 in the outer ring of steel bushing 40, ribbed stiffener 41 is symmetrical arranged and solid with base plate 12
Fixed connection.Additionally, top board 11 and base plate 12 are made by steel plate.
In use, can be connected fixing with the top of jack 1 by its steel bushing 40 by horizontal sliding device,
The elongation of regulation jack 1 makes top board 11 hold out against with by jacking thing 2, can carry out the top of jack
Rise or unloading construction so that by the direction of the horizontal displacement of jacking thing 2 with apart from controlled, thus avoid occurring
The security incident that jack 1 topples and causes.
Accordingly, the present embodiment additionally provide of the present utility model can horizontal sliding device jack construct
Using method in (jacking or unloading).Incorporated by reference to referring to figs. 2 to Fig. 8, one can horizontal sliding device
For the using method of jack construction, comprise the following steps:
S001: installing can horizontal sliding device: the gag lever post 52 of regulating base board 12 makes top board 11 be positioned at
Center, and jack 1 top is upwards recalled certain distance, steel bushing 40 is inserted in jack 1
Top；
S002: the jack 1 of horizontal sliding device can be placed into precalculated position by being provided with, regulate very heavy
The elongation on top 1 so that top board 11 upper surface holds out against with by jacking thing 2.
Especially, in step S002, certain distance is 60mm～100mm, to facilitate steel bushing 40 to be inserted in
The top of jack 1.
In sum, of the present utility model can horizontal sliding device, including the top board of a pair horizontally-parallel setting
And base plate, it is convex stupefied that top board bottom surface is provided with " T-shaped ", and plate top surface is provided with stupefied match convex with " T-shaped "
Chute, top board can pass through T-shaped " convex stupefied along chute relative to base plate slide；A connection piece, even
Fitting includes some groups of roller bearings and the roller support being correspondingly arranged on base plate, and roller bearing passes through roller support sandwiched
Between top board and base plate, top board can be relative to floor level sliding by roller bearing；One steel bushing, steel bushing
Cylinder is fixed on the lower end of base plate；And a stopping means, the detachable end being connected to base plate of stopping means.
This stopping means is for limiting the distance of upper plate horizontal sliding and carrying out the most spacing.This can horizontal sliding device
