Abstract

The utility model provides a rail roller type trolley which is a rail carrying trolley, belonging to the technical field of the railway vehicle. The utility model is characterized in that a plurality of integral roller 6 devices are formed by connecting plates 9 in a roller box 5, because the number of rollers is large, the contact stress between the rollers and steel rails is reduced, then bearing capacity of the utility model is enhanced, because the diameter of the rollers is small at the same time, the height of the utility model is reduced, the stability of the running of the utility model is enhanced, and a layer of polytetrafluoroethylene sliding blocks 2 are arranged between a crossbeam 3 and a turning pressure bearing plate 1 for satisfying a turning need. The utility model not only can be used for rail transports, but also can run on roadway laid with flat plates, and the utility model is especially suitable for the transport and the erection of the large-scale beam-shaped structural member.

Description

Roller railway bench cart

The utility model relates to a kind of railroad track delivery roller type chassis.

Set up large-span steel girder, the beam equipment that moves of military beam or large-span steel-reinforced concrete beam mostly is rod thick stick or slide block, but wayward in moving Liang Dacheng, time-consuming, takes a lot of work in the past.

The purpose of this utility model is just at the deficiencies in the prior art, and provides a kind of simple in structure, and from heavy and light, load carrying ability is big, the track roller type chassis of easy accessibility.

The utility model be achieved in that this track roller type chassis by sliding bearing partly and crawler body form, it is characterized in that: the sliding bearing part is by crossbeam 3, slide block 2, turn to bearing plate 1 to form, and slide block 2 is loaded on and turns between bearing plate 1 and the crossbeam 3, crawler body is by roller case 5, case lid 7, roller 6, track adjusting wheel 4, gage tie bar 8 is formed, roller 6 is fixed in the roller case 5 by bearing pin by connecting panel 9, track adjusting wheel 4 is loaded on roller case two ends, two gage tie bars 8 are contained in the tank ends inboard and connect with the wheel shaft of track adjusting wheel 4, case lid 7 spiral-locks are in roller case 5 upper ends, crossbeam 3 and case lid 7 Bolt Connection.

Fig. 1 is the utility model front view.

Fig. 2 is the utility model birds-eye view.

Fig. 3 is the utility model spatial structure split figure.

The utility model roller case 5 is a weldment, a plurality of rollers are by connecting panel 9, bearing pin is assembled into an integral body, be contained in the roller case 5, act on similar as the crawler belt of tank, play walking and be loaded on the two ends of roller case for areal of support (rail or be covered with the ground of steel plate) track adjusting wheel 4, keep the service direction of roller type chassis Load Transfer.Two gage tie bars 8 are contained in the inboard of tank ends, connect with the wheel shaft of track adjusting wheel, make two roller casees form one, and the inboard distance of scalable guide wheel rim is 1353 ± 3.Case lid 7 spiral-locks are in roller case upper end, crossbeam 3 and case lid 7 Bolt Connection are got tetrafluoroethylene slide block 2 and are loaded on and turn between bearing plate 1 and the crossbeam 3, are coated with lubricant on polytetrafluoroethylene piece surface for reducing friction, as butter etc., turn to bearing plate to move relative to crossbeam together with load.

The maximum characteristics of this track roller type chassis: structurally adopted roller to replace traditional wheel, because of the diameter of roller little, (it is 490 millimeters that the roller type chassis adds the total height of crossbeam to have reduced the height of chassis, the height of flatcar is the 1100-1300 millimeter on the railway), increased riding stability, simultaneously the quantity of roller is many, has reduced the contact stress with rail, thereby has improved load-carrying capacity.

Claims
