Existing another kind of pull tension gauge platform is as shown in Figure 2, and this pull tension gauge platform is made up of special-purpose hitch, towbar, force cell, frame, screw rod, nut, casing, speed reduction unit etc.
Speed reduction unit drives the nut rotation, and drive screw moves forward and backward, and directly drives force cell, towbar, special-purpose hitch telescopic moving.Because screw rod, nut, variator are at same axis, the displacement of screw rod is restricted, and still adopts special-purpose hitch.The hauling capacity of a locomotive is passed to ground through frame.
The shortcoming of this existing pull tension gauge platform is following:
1) the flexible distance of hitch is restricted, and long distance need increase pull bar, inconvenience when adjusting.
2) still do not have anti-fracture safeguard structure, potential safety hazard is arranged.
3) to bear section axial stressed for variator, fragile variator.
4) poor stability during the hitch pressurized is not easy to locomotive and accurately locatees.
5) special-purpose hitch versatility is poor.
Above-mentioned two kinds of technical schemes are present existing programs, through the prior art scheme is analyzed and improved, propose new technical scheme.
The utility model content
The purpose of the utility model is to overcome weak point of the prior art, provides a kind of compact conformation, hitch telescopic moving apart from big engine static-state rolling rig pull tension gauge platform.
1) structure is compact as far as possible, and hitch telescopic moving distance is big, basic compatible all kinds locomotive coupler centre distance requirement at present.
2) pull tension gauge platform reasonable stress reduces upsetting moment, improves security.
3) adopt No. 13 hitches of GB, solve versatility and convenience issue.
4) adopt anti-fracture structure, be provided with sissy bar, form mechanical second protection, improve security.
5) can bear locomotive coupler tractive force, can be convenient to control locomotive and move for locomotive provides pulling force and pressure again, accurately test efficiency is improved in the location.
This engine static-state rolling rig pull tension gauge platform, reducer shaft and screw rod parallel, and are screwed with nut on the screw rod, and the sprocket wheel on the reducer shaft is connected through chain with sprocket wheel on the nut, and an end of screw rod is connected with the traction device for measuring force.The rotation of reducer shaft drives the nut rotation, and the nut rotation drives screw rod and does straight reciprocating motion, and the to-and-fro movement of pulling traction device for measuring force is accomplished locomotive wheel and rail wheel centering and draw bar pull simultaneously and measured.The traction device for measuring force comprises guide frame, force cell, traction bars, the hitch that connects successively from inside to outside.Also be provided with sissy bar and safety switch between guide frame and the traction bars.Hitch is No. 13 hitches of GB.
Behind the hitch and locomotive coupler hook of pull tension gauge platform; Press the gear train action button, the energising of gear train motor is through traction device for measuring force pulling locomotive or promotion locomotive; Position to locomotive is adjusted, and the hitch shift motion limits within the specific limits.
The pass order of the hauling capacity of a locomotive is: locomotive coupler-traction bars-force cell-screw-and-nut-frame-ground.
When starting locomotive, the force cell on the traction device for measuring force is exported electric signal and is presented on the instrument with digital form, and signal is passed to central control board.Be provided with force cell between guide frame and the traction bars, and also be provided with sissy bar and safety switch.When the force cell failover was broken off, traction bars moved along sissy bar, bears the hauling capacity of a locomotive by sissy bar.Simultaneously, the safety switch action, locomotive shuts down, and traction stops.
The utility model compared with prior art has following advantage:
1) the flexible restriction that does not receive retarder location of screw rod, the flexible distance of hitch is big, compact conformation, compatible present all kinds of locomotive coupler centre distance requirement.
