SUMMERY OF THE UTILITY MODEL
The utility model aims at solving among the prior art dual-purpose car of public railway leading wheel and having hydraulic system trouble through hydraulic control, cause the vehicle can't travel, the leading wheel does not have stop device's shortcoming, and the dual-purpose car of public railway leading wheel elevating gear who provides.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
road-rail dual-purpose vehicle leading wheel elevating gear, which comprises a carriage body, bottom of the vehicle body swing joint has the hydraulic stem, and the welding of bottom of the vehicle body has the mounting bracket, inboard bottom of the mounting bracket has the supporting legs through round pin axle swing joint, supporting legs tip movable mounting has the leading wheel, and the welding of mounting bracket one side has the contact plate, and the mounting bracket is located electric telescopic handle is installed to the adjacent both sides of contact plate, the telescopic end of electric telescopic handle has the connecting block, the inboard welding of connecting block has the supporting shoe, and surface welding has the backing sheet on the supporting legs, and supporting legs both sides swing joint has the installation piece.
Preferably, the telescopic end of the hydraulic rod penetrates through and extends to the outer side of the bottom of the mounting block, and the bottom of the hydraulic rod is connected with a nut through threads.
Preferably, reinforcing ribs are welded at the bottom of the supporting sheet on two sides of the supporting leg.
Preferably, the supporting block is clamped between the supporting sheet and the contact plate, and a slope is arranged at the bottom of the supporting block.
Preferably, the surface of the hydraulic rod is welded with a limiting ring, and a spring is sleeved between the limiting ring on the surface of the hydraulic rod and the mounting block.
The utility model has the advantages that:
when the guide wheel of the road-rail dual-purpose vehicle runs on a rail, the lifting device is in an extending state, the guide wheel is effectively limited, and the condition that hydraulic system faults lead to the fact that a guide wheel control rod loses hydraulic pressure force to cause the fact that the vehicle cannot run is avoided.
Drawings
Fig. 1 is a schematic structural view of a guide wheel lifting device of a combined car of the utility model;
fig. 2 is the utility model provides a structural schematic diagram is looked sideways at to combined car leading wheel elevating gear's part.
In the figure: 1. a vehicle body; 2. a hydraulic lever; 3. a mounting frame; 4. supporting legs; 5. a guide wheel; 6. a contact plate; 7. an electric telescopic rod; 8. connecting blocks; 9. a support block; 10. a support sheet; 11. and (7) installing the block.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-2, combined car leading wheel elevating gear, including automobile body 1, 1 bottom swing joint of automobile body has hydraulic stem 2, 1 bottom welding of automobile body has mounting bracket 3, 3 bottom inboards of mounting bracket have supporting legs 4 through round pin axle swing joint, 4 tip swing joint of supporting legs have leading wheel 5, 3 side welding of mounting bracket has contact plate 6, mounting bracket 3 is located the adjacent both sides of contact plate 6 and installs electric telescopic handle 7, 7 telescopic end of electric telescopic handle is fixed with connecting block 8, 8 inboard welding of connecting block has supporting shoe 9, 4 upper surface welding of supporting legs have backing sheet 10, 4 both sides swing joint of supporting leg have installation piece 11.
The flexible end of hydraulic stem 2 runs through and extends to the bottom outside of installation piece 11, and threaded connection has the nut in its bottom, and 4 both sides of supporting legs are located the welding of backing sheet 10 bottom and have the strengthening rib, and 9 clamps of supporting shoe are located between backing sheet 10 and the contact plate 6, and 9 bottoms of supporting shoe are provided with the slope, and 2 skin weld of hydraulic stem has the spacing ring, and the cover is equipped with the spring between 2 surperficial spacing rings of hydraulic stem and the installation piece 11.
In this embodiment, when the combined vehicle needs to travel on the railway, hydraulic stem 2 stretches out, at this moment, 3 bottoms of mounting bracket descend through round pin axle swing joint's supporting legs 4, supporting legs 4 are rotatory downwards around the round pin axle, thereby the leading wheel 5 of 4 tip of control supporting legs falls to the ground, the flexible end of hydraulic stem 2 runs through and extends to the bottom outside of installation piece 11, installation piece 11 swing joint is in one side of supporting legs 4, consequently along with stretching out of hydraulic stem 2, its rotation can be followed to installation piece 11, reach the effect of control leading wheel 5.
