The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model embodiment clearer; To combine the accompanying drawing among the utility model embodiment below; Technical scheme among the utility model embodiment is carried out clear, intactly description; Obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The railway construction train that Fig. 1 provides for the utility model embodiment is looked scheme drawing with the master of vehicle frame, Fig. 2 be among Fig. 1 the railway construction train with the schematic top plan view of vehicle frame.
A kind of railway construction train is used vehicle frame, is connected to the two ends of bow beam 1 comprising bow beam 1 and 2, two sections straight beams 2 of two sections straight beams; Straight beam 2 tops are used to install driver's cab, and the bottom is used for being connected with bogie truck; Bow beam 1 is raise up arc when being in installing condition, the below of bow beam 1 bossing is used to hang parts to be installed.
After the vehicle frame installation, bow beam is as the main carrier that each parts is installed; And straight beam can transmit by the next tractive force of bogie truck transmission.The parts to be installed of suspension comprise power system, fuel tank, water tank and other accessory below the bow beam bossing.The driver's cab size of railway construction train is less, as long as the size of straight beam can satisfy the installation requirement of driver's cab.The bottom of bow beam is used to hang parts to be installed, and top equally also can installing component.The railway construction train that the utility model embodiment provides is used vehicle frame; Has bow beam; And when installing condition, bow beam is mounted to raise up arc, has so just increased the distance between vehicle frame and the ground; For the installation of parts provides more space, also increased the convenience of installing.The railway construction train that the utility model embodiment provides is used vehicle frame; Be used to be installed in railway with car; So crooked radian at the design bow beam; And during the height of having bent, should guarantee that whole vehicle frame is installed on the bogie truck after, can not influence the installation of upper parts and guarantee to transmit enough tractive forces.After Vehicle Frame Design become to have the structure of bow beam, be arranged on some parts of vehicle frame top originally, also can adopt the mode of suspension to be installed in the below of vehicle frame, so also reduced the height of gravitational center of car load to a certain extent, improve the stability of moving.
The preferred implementation of bow beam is: bow beam comprises longeron 11 and crosses bridging beam 12; Longeron 11 and straight beam 2 at interval and laterally arrange, are crossed bridging beam 12 and are obliquely installed on vertical direction, are fixedly connected between longeron 11 and the straight beam 2.
Consider the installation environment of vehicle frame, the bossing of bow beam adopts longeron and crosses bridging beam and realize that longeron is smooth on railway construction train longitudinal direction, provides convenience for upper parts is installed like this.Cross fixing between bridging beam and the longeron, and cross fixing between bridging beam and the straight beam and can adopt welding fixing, it is reliable to weld captive joint, and technology is simple.Need to prove; In Fig. 1, the structure of crossing bridging beam that is positioned at the longeron two ends is different, and the bridging beam excessively that is positioned at left end is straight; Be not with bending part; And the transition sill bolt that is positioned at right-hand member has bending part and straight portion, mainly is to consider the strained condition of weld seam and the convenience of manufacturing, guarantees the reliability of transmission of power simultaneously.
The angle of crossing bridging beam and horizontal surface is 35 °-60 °.Cross the angle of inclination of bridging beam and the length of longeron and determined the diff-H between longeron and the straight beam; Also just determined the height that vehicle frame arches upward; Use car for railway construction machinery; The angle of crossing bridging beam and horizontal surface satisfies above-mentioned scope can provide enough tractive forces, simultaneously at the upper and lower installing component of vehicle frame space and facility to be provided, also can not exceed rolling stock clearance [for railway.For the railway construction train of other types, the inclination angle scope of crossing bridging beam is slightly different.
Optional is that the quantity of longeron 11 is two, and is symmetrical set along the longitudinal central axis line of railway construction train; Two longerons 11 are through several support beam 3 captive joints; Two ends of every longeron 11 were passed through bridging beam 12 respectively and were captiveed joint with straight beam 2.
Adopting two longerons, can increase the stability of vehicle frame, between two longerons bridging beam was set, also is in order to increase the stability of body frame structure for automotive, also to facilitate for the installation of parts.
Particularly, between two straight beams 2 of longeron 11 same ends, be provided with strength beam 4.
It also is in order to increase the stability of whole body frame structure for automotive that strength beam is set.Need to prove, in Fig. 2, strength beam that form is set is different, the design of strength beam mainly is the connection mode of considering between this position of vehicle frame and underframe and the miscellaneous part, as long as can satisfy connection request.Be designed to the form of Fig. 2 right side strength beam, the couplet of being convenient between the vehicle is hung.
Further, longeron is a H-girder.The good stability of H-girder.Except that longeron, other beams can adopt the mode of steel plate welding to form, and the position of wanting of what is the need in office can be provided with floor, so that the structure of vehicle frame is more reliable and more stable.
The material of longeron, mistake bridging beam, straight beam, support beam and strength beam can all be a structural carbon steel.In the application, should select low-alloy high-tensile structural steel for use, the domestic trade mark can be selected Q345 and Q390 for use, and the external trade mark can be selected ST52 for use.
The utility model embodiment also provides a kind of railway construction train, comprises bogie truck and driver's cab at least, wherein: also comprise the described vehicle frame of the utility model any embodiment; The bow beam of vehicle frame is raise up arc; The below of bow beam bossing hangs parts to be installed; Driver's cab is installed on the top of straight beam, and the bottom is connected with bogie truck.
The railway construction train that the utility model embodiment provides comprises Work machine, and the big parts Large-scale Railway that need be suspended is with construction machinery and equipment etc.The railway construction train that the utility model embodiment provides has bow beam, has increased the distance between vehicle frame and the ground, for the installation of parts provides more space, has also increased the convenience of installing, and has reduced the center of gravity of railway construction train.
What should explain at last is: above embodiment is only in order to the technical scheme of explanation the utility model, but not to its restriction; Although the utility model has been carried out detailed explanation with reference to previous embodiment; Those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these are revised or replacement, do not make the spirit and the scope of each embodiment technical scheme of essence disengaging the utility model of relevant art scheme.
