Connection inside two elements.For the ordinary skill in the art, above-mentioned term can be understood at this with concrete condition
Concrete meaning in invention.
Truck scale is also referred to as weighbridge, is the main weighing-appliance for metering, and chief component is mass sensor,
Weighing platform table top, instrument, terminal box, data line.When mass sensor is installed in tunnel, need first the ground to installation site into
Hydraulic jack is placed on the reinforcing platform by mass sensor and supports weighing platform platform convenient for better stress by row consolidation process
Face.
Referring to Fig. 1, a kind of truck scale table top lifting device of the present invention, including be set in the tunnel 3 of truck scale and be used for
It is lifted the hydraulic jack 1 of weighing platform table top 2, the pedestal of hydraulic jack 1 is equipped with auxiliary support assemblies.
Auxiliary support assemblies can prevent weighing platform table top 2 from rising after when jack failure occurs Auxiliary support entire scale
Platform table top, increases safety coefficient.
Auxiliary support assemblies therein are the sleeve 4 being connect with 5 outer casing screw of oil pump of hydraulic jack 1.
5 shell wall of oil pump of hydraulic jack 1 is bigger than ordinary jack, in one section of saw-tooth thread of oil pump housing turning,
The side angle of screw thread stress is 3 °, and other side corner is 30 °, since the inclination angle of buttless thread tooth form two sides is different,
The prodigious axial force of one direction can be born, sleeve 4 is by being threaded on 5 shell of oil pump of hydraulic jack 1, and support is high
Degree can be adjusted according to 1 lifting height of hydraulic jack, portable and easy to use, in this way, just in case 1 failure of hydraulic jack, piston
When bar 6 declines, still there are the housing supports on the oil pump 5 for being connected to hydraulic jack 1 weighing platform table top 2.
Auxiliary support assemblies further include the bolt collar 8 being fixed on 1 pedestal of hydraulic jack, in bolt collar 8
Coaxial threaded is connected with bolt 9, and rotating bolt 9 makes it rise until contacting weighing platform table top 2 and playing Auxiliary support to table top.
It adds 9 threaded connection bolt sleeve 8 of bolt again on the basis of original Auxiliary support and supports weighing platform table top 2,
In this way, just in case 1 failure of hydraulic jack is still connected on 1 pedestal of hydraulic jack and bolt collar 8 when piston rod 6 declines
The bolt 9 of connection supports weighing platform table top 2.
Hydraulic jack 1 is double loop binodal hydraulic jack, and is equipped in the second section of 1 piston rod 6 of hydraulic jack
Static-pressure lead screw 7 for finely tuning 6 stroke of piston rod.
During hydraulic jack 1 rises, since the out-of-flatness of ground can cause the height that each hydraulic jack rises
Spend it is inconsistent, when rising to range can pass through finely tune piston rod 6 on static-pressure lead screw 7 increase rising height.
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.The present invention being described and shown in usually here in attached drawing is real
Applying the component of example can be arranged and be designed by a variety of different configurations.Therefore, the present invention to providing in the accompanying drawings below
The detailed description of embodiment be not intended to limit the range of claimed invention, but be merely representative of the selected of the present invention
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without creative efforts
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Fig. 2 and Fig. 3 are please referred to, the present invention is as follows：
S1, several hydraulic jacks are put into the tunnel of truck scale, while rise or rising respectively each hydraulic pressure thousand
The piston rod on jin top, and weighing platform table top is jacked up, while keeping weighing platform table-surface level；
Wherein, each hydraulic jack is positioned over by mass sensor correspondingly, by hydraulic jack by scale
After platform table top tentatively jacks up, then by static-pressure lead screw the level of entire table top is finely adjusted, each hydraulic jack can be same
When lifting or independent-lifting, until from 90~100cm of road surface.
S2, rise auxiliary support assemblies touch the bottom surface of weighing platform table top to it, decline hydraulic jack, make hydraulic jack
Top and auxiliary support assemblies simultaneously play a supportive role to weighing platform table top, and the space below weighing platform table top can repair people convenient for cleaning
The disengaging of member；
Wherein, auxiliary support assemblies are sleeve, the jack stand being co-axially located on the outside of hydraulic jack oil pump
On bolt collar and bolt and/or wooden sleeper；
The sleeve being threadedly coupled on backing pump shell so that sleeve rises and touch the bottom surface of weighing platform table top, declines
Hydraulic jack makes hydraulic jack and auxiliary support assemblies play a supportive role simultaneously to weighing platform table top；
Rotating bolt make its rise until contact weighing platform table top bottom surface, decline hydraulic jack, make hydraulic jack and
Auxiliary support assemblies simultaneously play a supportive role to weighing platform table top；
Weighing platform table top can be assisted by increasing the wooden sleeper of placement beside hydraulic jack in step S2
Support.
Wooden sleeper is put under tactile weighing platform table top and is contacted its bottom surface, declines hydraulic jack, make hydraulic jack and
Auxiliary support assemblies simultaneously play a supportive role to weighing platform table top；
Spatial altitude below weighing platform table top is 90~100cm, and cleaning maintenance personal can be made easily to enter in tunnel,
Tunnel is cleaned, truck scale is maintained, after the completion of repair to be cleaned, can very easily leave tunnel.
S3, each hydraulic jack is risen again and props up weighing platform table top, then withdraw auxiliary support assemblies, then will be each
Hydraulic jack declines and weighing platform table top is made to reset.
In whole process by observe Horizontal measuring apparatus state simultaneously or separately one by one control hydraulic jack rise or
Weighing platform table top is fallen, adjusting hydraulic jack one by one when finding that some steel plate falls unstable makes entire weighing platform table top keep water
It is flat to be raised or fall.
The present invention can quickly and easily be lifted weighting platforms of vehicle scale table top, and it is daily that the personnel of maintaining easily enter progress in tunnel
It safeguards and clears up, need not additionally occupy remaining track, operating process is simple, is easy to carry about with one, and can while control respectively
The movement of each hydraulic jack, will not damage original circuit, management easy to maintain.The lifting apparatus used is with more
Weight auxiliary support assemblies greatly reduce danger coefficient to ensure that hydraulic jack is safe to use.
The above content is merely illustrative of the invention's technical idea, and protection scope of the present invention cannot be limited with this, every to press
