Description
Technical field
The present invention relates to a kind of wheel-rail type girder transporting vehicle, relate to a kind of rail vehicle for highway, railroad bridge transport specifically.
Background technology
Due to the efficiency of construction of Bridge Erector and security reliability high, so obtain application widely in global highway and railway bridge construction.Peak period is in highway in China and railway construction, simultaneously beam type and the special line for passenger trains (below Speed 200 km/h) of highway, railway transportation industrial siding are very similar with the beam type of common railway line, in order to utilize equipment to greatest extent, reduce production cost, just require a kind of erection construction requirement that can either meet railway T-shaped beam, the Bridge Erector of the T-shaped Beams Erection Construction of highway can be met again.Wheel-rail type girder transporting vehicle supporting with it also must meet the Bridge Erector under various operating mode, simultaneously in order to improve efficiency and the function of beam car as much as possible, beam car also must be allowed to complete except transport bridge other work.
Existing Railway Line is constructed, first all constructions and transporting equipment must meet railway clearance requirement, this just requires that Bridge Erector will set a roof beam in place and transport on existing line and just must appearance and size be controlled in certain value range, so also just requires that its appearance and size also must control in certain value range by beam car supporting with it.
Summary of the invention
Object of the present invention just in order to solve in above-mentioned prior art existing weak point provide a kind of there is the transport that can not only realize highway and railway T-shaped beam and can be supporting with various Bridge Erector the rail vehicle transported for highway, railroad bridge.
Object of the present invention realizes by following technique measures:
Of the present invention for highway, railroad bridge transport rail vehicle comprise by traction connector be connected successively accessory cart, drive chassis, passive chassis; An accessory cart wheel of the front and back accessory cart wheel centering of described accessory cart combines to adopting flat turn bearing pin and the mode of taking turns flat turn wearing plate is connected between accessory cart frame; Another accessory cart wheel combines to the mode of ball pivot wearing plate with taking turns with adopting flat turn bearing pin between accessory cart frame, (this structure makes accessory cart can realize four point cantact to form ball pivot, 3 balances, ensure that accessory cart passes through track switch smoothly, can travel in the orbital plane of irregularity again simultaneously), accessory cart is provided with generating set and electrical control cubicles; Described driving chassis is identical with the frame section structure of described passive chassis, include be arranged on equalizer by hinge intermediate transverse girder above carrier bar, be arranged on by hinge and carry boom support (the relative level gyration that this structure can realize equalizer and carrier bar, carrier bar and carry on the back between boom support on the back above carrier bar, carry boom support on the back and adopt roomy planar design, other purposes of beam car can be realized), and be arranged on the hydraulic power unit of carrier bar end; The walking structure of described driving chassis is by being made up of the driving dolly that independently power set drive of left and right beam frame end portion being arranged on equalizer by bearing pin respectively; The walking structure of described passive chassis is made up of the driven carriage in the left and right beam frame end portion being arranged on equalizer respectively.
The present invention is symmetrically arranged with two, left and right and contacts with carrier bar bottom surface carrier bar side bearing block above the intermediate transverse girder of described equalizer, also can ensure the safety traffic of beam car when beam car has unbalance loading; And wearing plate is set between equalizer and the mating surface of carrier bar; Between carrier bar and the mating surface carrying boom support on the back, wearing plate is set.
The wheel of the driving dolly of driving chassis of the present invention and the driven carriage of passive chassis is all provided with the parking braking hydraulic jack realizing vehicle parking, to realize the parking braking of beam car, guarantee that fortune beam dolly under any circumstance all can be braked, person during guarantee transport and the safety of equipment.
The centre of the accessory cart vehicle frame described in the present invention is up concave type structure, reduces accessory cart as much as possible and uses height, meet instructions for use.
General principle of the present invention is as follows:
Because beam car is wanted to pass through railway switch, when track irregularity, (i.e. twist irregularity) can ensure that beam car does not slide down simultaneously, beam car will keep certain speed to meet construction technology and efficiency in fortune beam process, same at beam car by also certain speed will be kept during railway switch, this just requires that each chassis above beam car will have turning function flexibly, simultaneously beam car by during bend due to the difference in height of rail level inside and outside the effect of centripetal force and railroad curve, can different pressure be produced to the boom support both sides of carrying on the back of beam car and make to carry on the back boom support distortion, in order to ensure transported bridge security, be provided with side bearing apparatus carrying on the back below boom support both sides, when carrying the distortion of boom support both sides on the back and being excessive, the power of this part is just born by side bearing, can ensure again that carrying boom support on the back rotates smoothly simultaneously.
The upright pinned connection of equalizer and carrier bar, wearing plate is added in the middle of equalizer and carrier bar, can horizontally rotate between equalizer and carrier bar, ensure that the front and back dolly in beam transportation vehicle can independently rotate, and can smoothly by the sharp radius curve between railway switch.Carrier bar with carry the upright pinned connection of boom support on the back, carrier bar adds wearing plate with carrying on the back in the middle of boom support, carrier bar and carry on the back between boom support and can horizontally rotate.Drive during to ensure fortune beam between chassis and passive chassis by mutual independent steering during curve.
Drive dolly and equalizer pinned connection, can realize driving dolly to rotate along track facade, when uneven (twist irregularity) appears in rail level, drive dolly or driven carriage due to the effect of gravity, have a wheel contact with rail level and ensure that beam car does not slide down all the time.
The present invention compared with prior art, has following beneficial effect:
1) solve the defect that traditional beam car can only travel on unidirectional rail level, can adapt to transport on different kinds of railways rail level, expand the use face of beam car, greatly reduce the production cost of unit in charge of construction, social benefit is obvious.
2) because this beam car can adapt to various Bridge Erector, greatly improve construction of railways efficiency, save construction cost.
3) because beam car have employed the structure of multistage independent steering, make the overall structure of beam car lightly attractive in appearance, whole height is low, fortune depth of beam is low, long distance transportation can be realized, help to realize Bridge Erector supporting with it and reduce construction height, both improve the security of fortune beam, and equally also can improve the safety coefficient of Bridge Erector.
4) carry boom support on the back and adopt roomy structure, also pack Bridge Erector for beam car and realize shifting between quick bridge providing feasibility, this just drastically increases the using function of beam car, accelerates construction speed, has saved construction cost.
5) drive dolly and driven carriage that secondary parking liquefaction cylinder is all installed, ensure that beam car has safe and reliable braking ability, ensure the security in fortune beam work progress.
Beam car of the present invention not only can meet the transport task of railway T-shaped beam, shifts operating mode between the complete machine bridge that simultaneously also can meet supporting Bridge Erector with it.
