Problems solved by technology
The car body is one-piece. Since other structures need to be assembled on the car body after the completion of the car body, and the prefabricated beams for bridge erection and rail rows for laying rails can work normally, the width of the car body is designed after completion. When the track is transported, it has reached a super limit, so that the track laying and bridge erecting machine cannot be organized normally during the empty car return or marshalling transport. It must be handled in accordance with the "Railway Overweight and Overweight Freight Transport Rules", which prolongs the operation cycle and guarantees time. Can not meet the needs of users, affecting the construction work of track laying and bridge erection, and brought a certain loss to the railway construction

Embodiment Construction
[0014] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0015] The invention relates to a new type of combined vehicle body for railway track laying and bridge erecting machines, such as figure 1 , figure 2 , image 3 shown. The combined vehicle body includes a central vehicle body 1, which is an original vehicle body part of the vehicle. According to the length of the middle car body 1 (generally the car body is relatively long), a reinforcing plate 2 is welded in n sections on both sides of the middle car body 1, and the reinforcing plate 2 is welded between the upper and lower cover plates of the middle car body 1 on the outer web 5. The reinforcing plate 2 is provided with a plurality of bolt holes, therefore, the reinforcing plate 2 plays a role of connecting the middle vehicle body 1 and other parts.
[0016] In addition, there are two single-web side beams 3, which are symmetrically arranged o...

The invention discloses a vehicle combined body for a railway rail laying and bridging machine. The vehicle combined body comprises an original middle body of a vehicle. The vehicle combined body is characterized in that: reinforcing plates are welded on two sides of the middle body at intervals of certain distance; meanwhile, two single web side beams are symmetrically arranged on two sides of the middle body, and the single web side beam has a '['-shaped structure consisting of upper and lower cover plates and a web; and the reinforcing plates on the two sides are connected with the webs in the single web side beams through bolts. After being butted, the upper and lower cover plates of the single web side beams are flush with the upper and lower cover plates of the middle body. During construction, the single web side beams are connected to the two sides of the middle body so as to widen the body and meet the working conditions of rail laying and bridging construction; and during main transportation, the single web side beams are detached to shorten the width of the body, so that the transportation of the vehicle does not exceed the limit, normal grouping can be performed, the operating cycle is greatly shortened, and the vehicle combined body is flexible and convenient.
Description
technical field [0001] The invention relates to a vehicle for railway track-laying and bridge-erecting machines, in particular to a combined body of the vehicle for track-laying and bridge-erecting machines. The invention can realize that the vehicles used for track laying and bridge erecting machines will not exceed the limit when returning empty cars or marshalling transportation, and make them stable and reliable during track laying and bridge erecting construction operations, providing a highly efficient transportation and operation structure. Background technique [0002] The vehicle for track laying and bridge erecting machine is the base car and basic part of the track laying and bridge erecting unit. After the vehicle is completed, it is necessary to assemble the machine arm, lifting beam trolley, driving machinery, electric power and other equipment on the vehicle body to form the track laying and bridge erecting machine. It is used for track laying and bridge erect...
