In figure, 1. hydraulic jack, 2. weighing platform table top, 3. tunnel, 4. sleeve, 5. oil cylinder, 6. piston rod, 7. static pressure adjusting screw, 8. bolt collar, 9. bolt, 10. LOAD CELLS.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
The invention provides a kind of table top lifting device for truck scale, its structure is see Fig. 1, comprise several hydraulic jack 1 for lifting weighing platform table top 2 be arranged at bottom truck scale tunnel 3, also be provided with several bottom tunnel 3 for supporting the auxiliary support assemblies of weighing platform table top 2, each auxiliary support assemblies is for preventing the accident falling after weighing platform table top 2 rise.
After auxiliary support assemblies can prevent weighing platform table top 2 from rising, when lifting jack occurring being malfunctioning, such as pressure release, leakage of oil, oil pipe burst etc., auxiliary support assemblies supplemental support can play whole weighing platform table top 2, adds safety coefficient.
Wherein, auxiliary support assemblies comprises the sleeve 4 be coaxially arranged on outside hydraulic jack cylinder 5, and sleeve 4 is threaded with oil cylinder 5, and rotational sleeve 4 makes it rise until contact weighing platform table top 2, and plays supplemental support effect to weighing platform table top 2.
Oil cylinder 5 shell wall of hydraulic jack 1 is larger than ordinary jack, at cylinder shell turning one section of saw-tooth thread, the stressed side angle of screw thread is 3 °, opposite side corner is 30 °, because the pitch angle of buttless thread tooth form dual-side is different, the axial force that one direction is very large can be born, sleeve 4 is by being threaded on oil cylinder 5 shell of hydraulic jack 1, bearing height highly can regulate according to hydraulic jack 1 lifting, portable and easy to use, like this, just in case hydraulic jack 1 is malfunctioning, when piston rod 6 declines, the housing supports be connected on the oil cylinder 5 of hydraulic jack 1 is still had weighing platform table top 2.
Auxiliary support assemblies also comprises bolt collar 8, and in bolt collar 8, coaxial threaded is connected with bolt 9, and rotating bolt 9 makes it rise until contact weighing platform table top 2, and plays supplemental support effect to weighing platform table top 2.
Original supplemental support basis adds again bolt 9 threaded connection bolt sleeve 8 and supports weighing platform table top 2, like this, just in case hydraulic jack 1 is malfunctioning, when piston rod 6 declines, the bolt 9 still having bolt collar 8 to connect supports weighing platform table top 2.
Hydraulic jack 1 is two-circuit binodal hydraulic jack, and is provided with the static pressure adjusting screw 7 for finely tuning piston rod 6 stroke on the top of hydraulic jack 1 piston rod 6.In hydraulic jack 1 rise process, the height that the out-of-flatness due to ground can cause each hydraulic jack to rise is inconsistent, can increase rising height when rising to range by the static pressure adjusting screw 7 on fine setting piston rod 6.
Present invention also offers a kind of elevating method of the table top lifting device for truck scale, see Fig. 2 and Fig. 3, specifically implement according to following steps:
Step one, several hydraulic jack 1 are put into truck scale tunnel 3 bottom, rise the piston rod of each hydraulic jack 1 at the same time or separately, by weighing platform table top 2 jack-up to from road surface 90-100cm.Finely tuned by the level of static pressure adjusting screw 7 to whole weighing platform table top 2 again.Wherein, each hydraulic jack 1 is positioned over each LOAD CELLS 10 side in tunnel 3 all one to one.
When LOAD CELLS 10 is installed in tunnel 3, need first to carry out consolidation process to the ground of installation site, hydraulic jack 1 is placed on the other reinforcing platform of LOAD CELLS 10 and is convenient to better stressed support weighing platform table top 2.
Step 2, rise auxiliary support assemblies are until it touches the bottom surface of weighing platform table top 2, and decline hydraulic jack 1, makes hydraulic jack 1 and auxiliary support assemblies jointly play a supportive role to weighing platform table top 2;
Spatial altitude below weighing platform table top 2 is 90-100cm, clean maintenance personal can be made to enter in tunnel 3 easily, clean, maintain truck scale tunnel 3, after maintenance to be cleaned completes, can leave tunnel 3 very easily.
Wherein, auxiliary support assemblies is the sleeve 4, bolt collar 8 and the bolt 9 that are coaxially arranged on outside hydraulic jack 1 oil cylinder 5, and/or wooden sleeper.
The method rising auxiliary support assemblies is that the sleeve 4 that rotary oil cylinder 5 shell is threaded, makes sleeve 4 rise and touch the bottom surface of weighing platform table top 2; Or rotating bolt 9 makes it rise until contact the bottom surface of weighing platform table top 2; Or, place wooden sleeper on hydraulic jack 1 side and supplemental support carried out to weighing platform table top 2.
Step 3, again rise each hydraulic jack 1 and prop up weighing platform table top 2, then auxiliary support assemblies is resetted, then each hydraulic jack 1 is declined and weighing platform table top 2 is resetted;
In the whole process of lifting, by eye-level surveying instrument state at the same time or separately one by one hydraulic control lifting jack 1 rise or fall weighing platform table top 2, when finding that certain steel plate regulates hydraulic jack 1 to make whole weighing platform table top 2 maintenance level raised or fall one by one when falling instability.
Device and method provided by the invention can lifting weighting platforms of vehicle scale table top quickly and easily, the personnel of maintaining easily enter in tunnel and carry out daily servicing and cleaning, do not need additionally to take all the other tracks, operating process is simple, be easy to carry about with one, the motion of each hydraulic jack or can be controlled respectively simultaneously, can not damage original circuit, be easy to maintenance management.The lifting apparatus used, with multiple auxiliary support assemblies, to guarantee hydraulic jack use safety, greatly reduces danger coefficient.
