Abstract
The utility model provides a vehicle body for a railway track-laying bridging machine, which comprises a framework type vehicle frame consisting of a left side beam, a right side beam, a front end beam and a back end beam. The front part of the vehicle frame is horizontally provided with a front center plate beam. The bottom part of the front center girder is provided with an upper center plate. A back center plate beam is horizontally arranged on the back part of the vehicle frame. The bottom of the back center plate beam is provided with the upper center plate. The inner sides of the front parts of the left side beam and the right side beam are symmetrically and respectively provided with two body side bearings centered on the upper center plate arranged on the front center plate beam. When the utility model is operated on a trunk line, the vehicle body with the front part and the back part respectively provided with a steering bogie with a center plate loading structure can meet the requirement of 120 Km/h business operation speed, and the requirements of large dead weight capacity, smooth operation, safety and reliability in the construction operation can be met when the front steering frame is replaced by the steering frame with a five-axis side bearing loading structure after the construction operation site is arrived.
Description
Technical field
The utility model relates to a kind of railway car body with track laying bridging machine vehicle, and it can realize that track laying bridging machine vehicle is steadily reliable when bridging operation is laid a railway track in heavy duty, speed limit not when empty wagons loopback or marshalling transportation, thus high efficiency transport structure mode is provided.
Background technology
Track laying bridging machine vehicle is the end car and the foundation of track-laying and girder-erecting machine group, it is one of special vehicle, still need after vehicle completion assembling horn, hanging beam dolly, actuating device machinery, electrical equipments etc. are formed track-laying and girder-erecting machine, for the track laying of holding concurrently of building bridge on the full gauge railway circuit.Do not need when the equipment vehicle is crossed rail transportation or conversion workyard and other flatcar marshalling connection is hung transportation having, maximum commercial operation speed is 80Km/h.
The track laying bridging machine vehicle that uses on the China railways mainly partly is made up of car body, bogie truck, air brake equipment, coupler and draft gear, hand brake device etc.The bogie structure form that vehicle adopts has multiple, mainly contains:
1) trailing or leading bogie is the side bearing loading structure, though this kind structure track laying is steady, side bearing loading is had relatively high expectations to circuit, and derailment accident all took place when empty wagons loopback and track laying.
2) trailing or leading bogie is the cartridge carrying structure, and this kind structure is strong to network adaptability, but car body is not steady during track laying.
3) forecarriage is that five next to axis hold carrying structure, and trailing truck is four axle center dishes carrying structures, and this kind structure both guaranteed the to lay a railway track stationarity and the big requirement of load-carrying of bridging operation have improved the adaptive capacity of vehicle to circuit again.
Because forecarriage satisfies operation pulsation-free needs again for the side bearing loading trailing truck is that this structure that cartridge carries had both adapted to the empty wagons loopback, so present track laying bridging machine vehicle all adopts this form, but its empty wagons loopback speed has only 80Km/h.Along with the continuous speed-raising of recent China railways lorry, the speed-raising problem when the empty wagons loopback of track laying bridging machine vehicle or conversion workyard also needs to be resolved hurrily.
The utility model content
In view of above-mentioned, the purpose of this utility model provides a kind of railway car body with track laying bridging machine vehicle, and it can realize that track laying bridging machine vehicle is steadily reliable when bridging operation is laid a railway track in heavy duty, speed limit not when empty wagons loopback or marshalling transportation.
For this reason, the utility model is by the following technical solutions:
A kind of railway track laying bridge formation machine carbody comprises the shaped as frame vehicle frame of being made up of left and right sides curb girder and front and back end carriage, and the vehicle frame front cross is established preceding cartridge beam, cartridge is installed in preceding cartridge beam bottom, the vehicle frame posterior transversal is established back cartridge beam, and cartridge is installed in back cartridge beam bottom, it is characterized in that:
Curb girder anterior inboard in the described left and right sides is that the center respectively is provided with 2 body side bearings symmetrically with the body center plate on the cartridge beam before described.
All adorn the bogie truck of cartridge carrying structure when on main track, moving before and after the car body, satisfy the requirement of commercial operation speed 120Km/h, after arriving the construction operation scene, change forecarriage into bogie truck that five next to axis hold carrying structure, the requirement that dead-weight capacity is big, operation is steady, safe and reliable when satisfying construction operation.
The beneficial effects of the utility model are: because the vehicle frame front cross is provided with preceding cartridge beam and body side bearing, therefore vehicle adopts the trailing or leading bogie that is the cartridge carrying structure when operation on main track, realized that the maximum commercial operation speed that vehicle moves has reached 120Km/h on main track, be consistent with the running velocity of China existing railway truck, its transportation marshalling is not all restricted, improved conveying efficiency greatly.And lay a railway track before the bridging operation carrying out heavy duty, then forecarriage is changed into the bogie truck that five next to axis hold carrying structure, thereby realized that the heavy duty Bridging Vehicle operation of laying a railway track is steady, safe and reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment
Be described further below in conjunction with accompanying drawing.
Be the structural representation of the utility model railway as depicted in figs. 1 and 2 with track-laying and girder-erecting machine car car body.It comprises the shaped as frame vehicle frame of being made up of left and right sides curb girder and front and back end carriage 1, the vehicle frame front cross is provided with preceding cartridge beam 2, cartridge 3 is installed in preceding cartridge beam bottom, the vehicle frame posterior transversal is established back cartridge beam, cartridge is installed in back cartridge beam bottom, left and right sides curb girder anterior inboard before body center plate 3 on the cartridge beam 2 for the center 2 body side bearings 4 are set respectively symmetrically.
4 body side bearing 4 solid weldings of vehicle frame 1 front portion are in the inboard of left and right sides curb girder; The central authorities of cartridge beam 2 before anterior body center plate 3 is bound up on by existing railway standard, the body center plate at rear portion is bound up on the central authorities of back cartridge beam.
When laying a railway track bridging operation, Vehicular body front adopts five next to axis to hold the bogie truck of carrying structure, and rear vehicle adopts the four-shaft steering of cartridge carrying structure.At this moment, 4 body side bearings 4 cooperate the back as load bearing component with side bearing loading five axle bogies, and the body center plate 3 on the preceding cartridge beam 2 does not carry, and only play guiding and transmit longitudinal force.
During the empty wagons loopback, the bogie truck of rear vehicle remains unchanged, but Vehicular body front is used the four-shaft steering of cartridge carrying structure instead.At this moment, the body center plate 3 on the preceding cartridge beam 2 and cartridge carrying four-shaft steering cooperates, and is the same with existing general purpose freight car, belongs to the cartridge carrying, do not contact any position and 4 body side bearings 4 are unsettled, to reach the purpose that the main track transportation is raised speed.
