Lower vehicle body of plate type ballast bed plate-adjusting vehicle

Abstract

The invention provides a lower vehicle body of a plate type ballast bed plate-adjusting vehicle. The lower vehicle body is characterized by comprising a frame body composed of a bottom plate (1) and asurrounding plate (2), and the frame body is partitioned into a set of wheel mounting slots (3), a set of jacking cylinder mounting slots (4), a set of telescopic cylinder mounting slots (5), a movable panel mounting slot (6) and a cable connecting slot (7) through a set of partition plates (2a). Wheels (3a) are arranged in the wheel mounting slots (3), jacking cylinders (4a) are arranged in thejacking cylinder mounting slots (4), and telescopic cylinders (5d) are arranged in the telescopic cylinder mounting slots (5). A cover plate (12) matched with the frame body in a corresponding mode isfurther disposed on the frame body. The lower vehicle body of the plate type ballast bed plate-adjusting vehicle is simple in structure and convenient to manufacture, the structural strength of the lower body is high, and all components on the lower body are provided with independent installation space, and mutual interference is avoided during the components work.

Description

Technical field: [0001] The invention relates to a prefabricated slab-type construction equipment for ballastless track construction, in particular to a lower body of a slab-type ballast bed adjustment vehicle. Background technique: [0002] In the construction of the floating slab track, it is necessary to splice and assemble the prefabricated slab track bed into a floating track bed. At present, the splicing of prefabricated slab track beds mainly depends on the placement of hoisting equipment, and then adjusts the position accurately manually. Because the prefabricated slab track bed has a large weight, large inertia, and large shaking range, the placement error of hoisting equipment is relatively large, and manual adjustment is required. It is time-consuming and labor-intensive, and it is often necessary to repeatedly lift and lower the prefabricated slab track bed, especially after using a short prefabricated slab track bed, the number of splicing during construction is...

Problems solved by technology

At present, the splicing of prefabricated slab track beds mainly depends on the placement of hoisting equipment, and then adjusts the position accurately manually. Because the prefabricated slab track bed has a large weight, large inertia, and large shaking range, the placement error of hoisting equipment is relatively large, and manual adjustment is required. It is time-consuming and labor-intensive, and it is often necessary to repeatedly lift and lower the prefabricated slab track bed, especially after using a short prefabricated slab track bed, the number of splicing during construction is greatly increased, so this forms a new bottleneck restricting the construction speed, and also consumes a lot of manpower and material resources. increased construction costs

[0003] Therefore, our company has applied for a pallet-adjusting vehicle with the application number 201610418277.5 for laying prefabricated slab-type track beds. However, during use, it was found that the lower body strength of the pallet-adjusting vehicle is low, and there are various movable parts installed in the lower vehicle body. Problems such as mutual interference often occur during work
