Embodiment 1

[0028] In this embodiment, the bogie 4 includes a drive wheel pair 41, a frame 42 and an axle box 43. The middle part of the upper end surface of the frame is provided with a sinking structure 421. The sinking structure 421 is a streamlined depression with a sinking distance of 30 mm. The sinking structure 421 can be Reduce the overall height of the car body 1, avoiding as far as possible when shipping large parts, the items on the car body 1 collide with the top of the underground roadway, so that the car body 1 can carry higher items; the wheel pair width of the driving wheel pair 41 1530mm, in order to meet the transportation in the limited space of the coal mine underground roadway and prevent the collision and interference between the flatbed truck and the roadway, the overall width of the bogie 4 needs to be shortened, and the overall width of the axle box 43 and the driving wheel pair 41 of the bogie 4 is set to be no greater than 2065mm, preferably 2065mm here, specific...

Embodiment 2

[0030] In this embodiment, the bogie 4 includes a drive wheel pair 41, a frame 42, and an axle box 43. A sinking structure 421 is provided in the middle of the upper end surface of the frame. The sinking structure 421 is an inverted trapezoidal depression with a sinking distance of 40mm. The sinking structure 421 The overall height of the car body 1 can be reduced, and the items on the car body 1 collide with the top of the underground roadway when large parts are avoided as much as possible, so that the car body 1 can carry higher objects; the wheels of the driving wheel pair 41 The width is 1530mm. In order to meet the transportation in the limited space of the coal mine underground roadway and prevent the flatbed truck from colliding with the roadway, it is necessary to shorten the overall width of the bogie 4. greater than 2065mm, preferably 2061mm here, specifically to optimize and reduce the cross-sectional width of the axle box 43 and the frame 42, and use high-carbon st...

Abstract

The flat car comprises a car body, the car body is provided with a table top, a box girder structure is fixed to the lower end face of the table top, at least two pieces of H-shaped steel are fixed between the front end and the rear end of the box girder structure in parallel, and steel channels are oppositely arranged on the left side and the right side of the box girder structure; a plurality of rib plates are fixedly welded between the H-shaped steel and the channel steel; two bogies are fixedly attached to the lower end face of the table top along the front and rear center lines respectively; the front end and the rear end of the vehicle body are each provided with a traction connecting part, the portions, on the two sides of the traction connecting parts, of one end of the vehicle body are provided with single-side double-wheel hand braking systems in a matched mode, and through the arrangement of the box girder structure, the bearing capacity is large, structural matching is compact, transmission is little, and the fault rate is low; the vehicle body moves upwards and stops freely on an underground track, and the technical problem that in the prior art, TBM large-scale components cannot be integrally transported underground through the track can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of auxiliary equipment for full-face tunnel boring machines, and in particular relates to a flatbed car used for underground rail transportation of large TBM components. Background technique [0002] TBM is a full-face tunnel boring machine, which is used to perform parallel and continuous operations in construction procedures such as excavation, support, and slag discharge. With the advantages of high speed, environmental protection, and high comprehensive benefits, it can realize the construction of long tunnels buried in complex geographical landforms that are difficult to achieve with traditional drilling and blasting methods. The construction period is relatively tight, and improving the efficiency of TBM transition will undoubtedly have a great influence on the progress of each construction period and the cost of engineering operations. [0003] The TBM shield machine has a self-weight of about 700T a...
