Abstract
The utility model discloses an underneath pass heavy haul railway Line reinforcing device which comprises a D 24-shaped beam which is provided with a beam (2) and two carlings (1). The reinforcing device is characterized in that a flanged beam (6) is connected with the beam (2) of the D 24-shaped beam. Both ends of the flanged beam (6) are respectively connected with the two carlings (1) of the D 24-shaped beam through a bottom flange plate (5). The connecting pins of the beam (2) and carling (1) of the D 24-shaped beam are provided with a top flange plate (3) which is respectively connected with the beam (2) and carling (1). The beam (2) of the D 24-shaped beam is connected with the carling (1) of the D 24-shaped beam through a gusset piece (4) which is connected with a middle flange plate. The reinforcing device can be used in the business line of the heavy haul train or the bridge and culvert. Without interrupting the travelling crane, the excavation of the bridge culvert foundation pit and the housing construction can also be carried out.
Description
Technical field
The utility model relates to a kind of heavy haul railway track strengthening device, is mainly used in the construction of heavy haul train track strengthening.
Background technology
In the bridges and culverts construction of the Business Line of train or the field of standing, unimpeded for what guarantee to transport, in the situation that do not cut off traffic, usually utilize the just beam hardened link of constructing, thereby the excavation and the casing that carry out the bridges and culverts foundation ditch are constructed.D24 type just beam is that commonly use, important temporary line ruggedized construction, and it uses very extensive in railway bridges and culverts construction, adopt the D24 type just the beam hardened link under the prerequisite that does not cut off traffic, both can guarantee traffic safety, what can guarantee again to construct carries out smoothly.But in the heavy haul railway track strengthening, there is no at present case history can use for reference.Along with the fast development of railway transportation, at present increasing heavy haul railway is being built and is being come into operation successively, is a present difficult problem in the urgent need to address for wearing down the heavy haul railway track strengthening.
Summary of the invention
For the defects that exists in the prior art, the utility model provides a kind of heavy haul railway track strengthening device that is applicable to down wear, and utilizes its energy accelerating construction progress.Improve efficiency of construction.
The utility model is achieved by the following technical solution: wear heavy haul railway track strengthening device under a kind of, comprise the just beam of D24 type that is provided with crossbeam and two longerons, its special character is, the D24 type just the crossbeam beam downside of beam be bolted an i beam, the two ends of described i beam respectively by connected bottom wing listrium and D24 type just two longerons of beam be connected, D24 type just crossbeam and the longeron link of beam is provided with respectively the top flange plate that is connected with longeron with described crossbeam, described D24 type just beam crossbeam by the joint cover that is connected with wing plate wherein and D24 type just the longeron of beam be connected.
For the ease of dismounting and be convenient to recycling of parts, described top flange plate and D24 type just between the crossbeam and longeron of beam, bottom wing listrium and D24 type just between the longeron and i beam of beam, joint cover and D24 type just all be bolted between the crossbeam of beam and the longeron.
The utility model is by just adding the i beam that is connected with crossbeam under the crossbeam of beam in the D24 type, and i beam and D24 the type just longeron of beam laterally connect, and have improved the supporting capacity of bracing means, have strengthened the stability in the bracing means loading process; In addition, top flange plate, bottom wing listrium have further strengthened the resistance to overturning of bracing means, have improved supporting capacity.The utility model not only supporting capacity is large, and the assembly unit of when construction is convenient, can greatly improve efficiency of construction, and accelerating construction progress shortens the construction period.And part-structure can be recycled, and is conducive to reducing construction cost.The utility model is adapted to the bridges and culverts construction at the Business Line of heavy haul train or station, can in the situation that do not cut off traffic, carry out excavation and the casing construction of bridges and culverts foundation ditch.It can be widely used as a kind of important track strengthening structure.
Description of drawings
Fig. 1 is the structural representation in the utility model specific embodiment;
Fig. 2 is the A-A generalized section among Fig. 1;
Among the figure: 1, longeron, 2, crossbeam, 3, top flange plate, 4, joint cover, 5, the bottom wing listrium, 6, i beam, 7, connecting bolt.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in drawings, wear heavy haul railway track strengthening device under a kind of, it comprises just beam of D24 type, and D24 type just beam is prior art, and it comprises two longerons 1 and two crossbeams 2 between the longeron 1 are set.The D24 type just the crossbeam 2 beam downsides of beam be provided with an i beam 6, the upper flange of i beam 6 closely links together by connecting bolt 7 and crossbeam 2, the two ends of i beam 6 respectively by bottom wing listrium 5 bolted with it and D24 type just two longerons 1 of beam be bolted.The D24 type just crossbeam 2 of beam is respectively equipped with top flange plate 3 with longeron 1 link, and top flange plate 3 is connected with longeron by bolt and crossbeam 2 respectively and is connected.The D24 type just crossbeam 2 of beam and D24 type just is provided with joint cover 4 between the longeron 1 of beam, and joint cover 4 is connected with longeron with the middle wing plate of crossbeam 2 respectively by bolt and is connected.
Other parts in the present embodiment adopt prior art, do not repeat them here.
The utility model is by adopting just beam and under the crossbeam of just beam i beam is set of D24 type, improved the integrated carrying ability of bracing means, and stability under loading, utilize it to carry out the track strengthening of heavy haul railway, can guarantee railway operation safety, improve efficiency of construction.
