Description

Hand hydraulic equipment for railway rescue

The utility model relates to a kind of hand-hydraulic re-railing equipment that is used for the railways train operation accident rescue.

At present, domestic railways train operation accident rescue is generally sent breakdown train, hangs or other hanging device has come multiple accident rolling stock with large-scale steam, usually because of accident site is too far away, and incurs loss through delay salvage work.Such as bridge, tunnel or electrified sections, large-scale hanging device can't be put to good use at all.Given this, by " the rolling stock derailing hydraulic pressure re-railing equipment " of the production of Guangdong one tame rolling stock plant, in playing multiple process, because the hydraulic efficiency pressure system poor sealing performance, leakage is serious, causes top lift can not reach requirement of actual working condition in the recent period; The Traverse Displacement Unit movement in one direction lacks alerting ability.

The purpose of this utility model is: adopt a kind of rolling stock that makes of hydraulic-driven technical design in playing multiple operation, can obtain reliable top lift; The hydraulic pressure re-railing equipment of jacking, Traverse Displacement Unit operation easily and flexibly.

Technical solution of the present utility model is: there is a rocking arm high-pressure oil pump top, the high-pressure oil pump below is fixed on the support, in the pump housing one side, have into, oil outlet pipe is communicated with hydraulic pressure switch operation platform, two pairs of turnover oil pipes are arranged at the operator's station bottom, wherein one dock traversing original text, another butt joint jacking original text, traversing original text is placed on the rerail bridge, and traversing original text one end is embedded on the traversing bearing on the rerail bridge, the other end links to each other with traversing dolly, be close to traversing dolly top and putting the pad that climbs, jacking pick plunger is placed in the pad top of climbing, outside the plunger, overlapping the ring that climbs, on the ring that climbs jacking pick end cap is being arranged.

Because the hand-hydraulic high pressure pump of above-mentioned solution has improved sealing property, guaranteed of the requirement of rescue operating mode to top lift.Traversing pick, jacking pick are adopted bidirectional-movement respectively, just, swing to the jacking mode of operation, make the more apparent maneuverability of system, have improved the rescue work operating mode.

Respective valve seat was in parallel during delivery valve seat and oil-feed valve seat were paid by oil duct in the pump housing and another plunger respectively, and was communicated on the pump housing accordingly into and out of oil pipe ［ 5 ］ by oil duct.

Be communicated with hydraulic pressure switch operation platform into and out of oil pipe ［ 5 ］, two pairs of turnover oil pipes are arranged at the operator's station bottom, and wherein a pair of oil pipe ［ 7 ］ connects jacking pick ［ 11 ］, and another connects traversing pick ［ 14 ］ to oil pipe ［ 6 ］.

With reference to accompanying drawing 1,4, jacking pick ［ 11 ］ is a cylinder, plunger ［ 51 ］ inserts in the pick scapus plug sleeve ［ 49 ］, the contacted center position of plunger head and plunger sleeve top, one cylindrical poultry oil pocket ［ 55 ］ is arranged, and oil duct ［ 56 ］ is communicated with cavity with the inlet nozzle ［ 7 ］ of the external side of pick.Plunger upper part projection section ［ 48 ］ engages with pick scapus plug sleeve, and the plunger projection section has circular groove, and O RunddichtringO ［ 47 ］ is housed in the groove, and space ［ 50 ］ is left in plunger boss bottom between plunger body and the plunger sleeve.

One ring-type pick body lid ［ 53 ］ is arranged at pick body bottom, and along a bulge loop ［ 60 ］ perpendicular to the lid plane is arranged on the annulus in the lid, the lucky contract of bulge loop is gone in the space of leaving between plunger and plunger sleeve.

The joint of pick body lid and outer plunger surface, pick scapus plug sleeve, pick body end is embedded with O RunddichtringO ［ 59 ］, ［ 57 ］, ［ 58 ］ respectively.

Pick body lid connects together with the pick body with hexagonal gong nail ［ 54 ］ in the cylinder.On the pick body sidewall at the maximum position place of plunger stroke, " limit position safety return-flow valve " ［ 52 ］ are housed, and have oil pipe to be communicated with backflow oil nozzle ［ 7 ］.

With reference to accompanying drawing 1,5, traversing pick ［ 14 ］ is a long barrel shape, in the left end cap ［ 65 ］, in left end cap eck ［ 66 ］ outer rim one concave ring groove ［ 71 ］ is arranged, concave ring groove opening part and pump housing left end are and agree with structure, and concave ring groove combines for spiral with the outside face ［ 72 ］ of pump housing left end; Go into to combine for contract with inside face ［ 70 ］, its faying face has an O RunddichtringO ［ 79 ］.

Along the faying face of left end cap eck and piston rod ［ 73 ］, dust ring ［ 69 ］, YX RunddichtringO ［ 77 ］, O RunddichtringO ［ 78 ］ are housed successively.

A left side cut somebody's hair ［ 67 ］ be positioned at pump housing left end, it is the cylinder that there is a groove neck ［ 68 ］ at a middle part, its right-hand member piston rod ［ 73 ］ of ining succession, its bar enters the pump housing from the left end cap eck, link to each other with bidirectional piston ［ 64 ］ left end, the piston right-hand member also is connected with piston rod, by pump housing right output port ［ 63 ］ cut somebody's hair with the right side ［ 61 ］ link to each other, cutting somebody's hair in the right side also is the cylinder that there are groove neck ［ 62 ］ at a middle part.

The bidirectional piston outside face has two annular grooves, the annular groove two side, and ring washer ［ 76 ］ in embedding respectively, is O RunddichtringO ［ 75 ］ in the middle of the ring washer.

Near pump housing two-port place, oil pipe ［ 6 ］ is housed respectively, the oil storage cavity ［ 74 ］ at bidirectional piston ［ 64 ］ two ends that the oil pipe ［ 6 ］ that is communicated with traversing pick ［ 14 ］ and the pump housing are interior communicates.

Rerail bridge ［ 16 ］ is that a cross-sectional plane is " duplex " font structure work post, is a plane on the bridge, along the some square brige holes of its line of centers rectangular distribution ［ 17 ］.

Traversing pick places on the rerail bridge floor, and the one end embeds and is being anchored on the traversing bearing ［ 15 ］ of the square brige hole of bridge floor, and the other end links to each other with traversing dolly ［ 8 ］ interface.Traversing dolly is a cuboid, its underpart is equipped with three pairs of steamboats, its wheel rim is placed on the corresponding rail level of rerail bridge " duplex " font, be close to traversing dolly top, putting the pad ［ 9 ］ that climbs, the pad top rotation jacking pick plunger ［ 10 ］ that climbs, plunger periphery, overlapping the ring ［ 13 ］ that climbs, on the ring that climbs pick body end cap ［ 12 ］ is being arranged.

With reference to Fig. 1, during use, the rerail bridge is placed in worked the part below of returning to work, traversing pick, jacking pick is put (jacking pick is by swinging to the storing of jacking mode of operation among Fig. 1) by above-mentioned connection mode.

Shake the high pressure manual pump,, plunger is supported on relies on the workpiece on the face of land by hydraulic pressure switch operation platform, because the antagonistic force of workpiece, the pick body jack-up weight that makes progress; Towards pick body bottom, the plunger peripheral space stacks the ring that climbs, and manipulation operations platform then is put into weight on the ring that climbs, and the operation plunger up gos up, and transfers the padding pad that climbs toward plunger, handles plunger action once more, the pick body jack-up weight that makes progress again again.So repeatedly, progressively finish the jacking operation.

When jacking pick is that plunger reaches the range place, in " limit position safety return-flow valve " effect that pick body one side is equipped with down, the pick body falls to being put into to climb with load and encircles, thereby has avoided pick body top cover to be damaged.

When by jacking workpiece wheel wheel rim being exceeded rail level 15-20mm, operating hydraulically operated reversing arrangement, is handled traversing dolly and is made transverse moving left and right according to rerail operation needs to traversing state.

When confirming by jacking workpiece wheel wheel rim all to be in the two rails rear flank, operating hydraulically operated change-over valve is alternately dismantled the ring that climbs, pad to the lifting position, until wheel tread contact rail rail level.
