Description

A kind of U-shaped jack
Technical field
A kind of U-shaped jack of the utility model, belongs to lifting device technical field.
Background technology
Horizontal jack is that one kind is widely used in support apparatus deadweight, adjusting device water on load-carrying vehicle or mobile device A flat important Hydraulic Elements, it is mainly used in the departments such as factories and miness, communications and transportation as Mechanical Help and other liftings, support Deng work;Its principle is mainly the object lower section that need to be supported by the way that the pallet of jack is positioned over, and passes through oil cylinder or cylinder Object is jacked to certain height etc. top lift part, operation is carried out below object so as to convenient.
Due between the pallet and support arm of jack being connected by articulated manner, therefore can not bear for a long time excessive Pressure, the problems such as otherwise producing deformation, in the prior art after jack stand weight, jack stand is put into weight Lower section, and pressure is born using jack stand, jack can then take out, without bearing pressure for a long time, so as to prevent Deformation, improve the life-span.
However, when placing jack stand, because jack is in occupation of the position of fulcrum, jack stand is to put Jack stand, therefore, can only be positioned over the side of jack fulcrum, thus can by the position of fulcrum where entering jack Cause the skew of fulcrum, require relatively stricter for fulcrum or the less situation of supporting surface, jack stand are to use 's.
Utility model content
The utility model overcomes the shortcomings of the prior art, there is provided a kind of U-shaped jack, using U-shaped pallet come The size of supporting surface is reduced, and supporting and space is provided for jack stand at fulcrum so that fulcrum is not offset.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is:A kind of U-shaped jack, including branch Brace, oil pump and base, the oil pump are located at the lower section of support arm, and the support arm is located at the top of base, the support arm By the flexible and raising or landing, in addition to U-shaped pallet of oil pump, the U-shaped pallet is into U-shaped opening structure, the U-shaped pallet Positioned at the end of support arm, the opening of the U-shaped pallet is towards the outside of support arm.
The A/F and the width of the strut ends of extraneous jack stand of the U-shaped pallet are adapted.
For the base into U-shaped opening structure, its opening direction is identical with the opening direction of U-shaped pallet.
Two side fixed plates are symmetrically arranged with the base, two rollers are respectively installed inside and outside described two side fixed plates, The side fixed plate passes through roller uniform stressed.
Connecting rod is provided with the support arm, the connecting rod forms quadric chain, institute with support arm and U-shaped pallet U-shaped pallet is stated by the regulation of connecting rod and all the time in horizontal upward.
Back-moving spring is provided between the side fixed plate and support arm.
The utility model has the advantages that compared with prior art:
The present apparatus replaces original pallet using U-shaped pallet, reduces on the basis of tray area and is in fulcrum position Extraneous jack stand provides supporting and space so that the fulcrum of jack stand overlaps with the fulcrum of screw block carrier, avoids Fulcrum is set to produce skew because of the skew of jack stand, for the supporting surface of small area, U-shaped pallet causes jack stand Other supporting surfaces are not take up, just with the supporting surface shared by U-shaped pallet so that jack stand fulcrum requirement strictly and It is equally applicable in the case that Area of bearing is small, expand the scope of application of jack stand;Other, U-shaped pallet and jack The pillar of support, which is engaged, to be caused the process for exchanging stress in jack and jack stand more steady and safely, avoids Because fulcrum change and caused by slip or jack stand topple over caused by security incident, reduce potential safety hazard.
Brief description of the drawings
The utility model is described further below in conjunction with the accompanying drawings.
