Abstract
The utility model discloses a vibration absorbing sleeper used to lay the steel rail of the railroad. The existing sleepers have the shortages of imperfect shock resistance, easy destruction of the antiseismic structure in actual use, short service life and frequent maintenance at later period. The vibration absorbing sleeper comprises a sleeper body and a rib rack in the sleeper body. The vibration absorbing sleeper is characterized in that the rib rack is a rigid rib rack, and the sleeper body is an elastic sleeper body which is cast with the rigid rib rack in one piece. The one-piece sleeper supports the steel rail by the rigid rib rack and the elastic sleeper with certain compressive strength during use, and the effect of vibration absorption is good; because of the one-piece structure of the vibration absorbing sleeper, the vibration absorbing sleeper can be used long once laid on the railroad, and the frequent later period maintenance is avoided.
Description
[technical field]
The utility model relates to a kind of sleeper that is used to lay track, especially a kind of shock-absorbing sleeper of the rail that is used to place an iron railway.
[background technology]
In railway construction and since rail be a section be laid on the sleeper, when train speed from rail out-of-date, can produce very big vibrations, therefore, the sleeper that is used for supporting rail should have shock resistance, with the security of operation of assurance train and the life-span of advancing the track.Sleeper the earliest is to handle the sleeper of making by charing with timber, but because the scarcity of the forest reserves, seldom re-used this sleeper at present, but with the sleeper of reinforced concrete structure, the sleeper of this rigid structures has bigger intensity, thereby be used widely, but its anti-seismic performance is bad, so the technical measures of this rigidity sleeper of various improvement are arisen at the historic moment, such as on existing sleeper, antidetonation cushion etc. being set, yet the earthquake resistant structure of this minute body structure is damaged in actual use easily, and the life-span is short, and later maintenance is frequent.
[utility model content]
The technical assignment of the technical problems to be solved in the utility model and proposition is to overcome existing existing technological deficiency of sleeper and deficiency, and a kind of integral type sleeper with good resistance shock stability is provided.For this reason, the utility model is taked following technical proposals:
The shock-absorbing sleeper comprises the muscle frame of sleeper body and Qi Nei it is characterized in that described muscle frame is the rigid rib frame that described sleeper body is the elastic sleeper body, the two cast solid.The sleeper of this integral type, in use by the rigid rib frame with elastic sleeper supporting rail with certain compressive strength, have good shock-absorbing effect, and because this sleeper is an integral structure, once being laid on the railway, just can use for a long time, avoid frequent later maintenance.
As the further of technique scheme improved and replenish, the utility model can adopt following technical measures:
Described elastic sleeper is for being grain with the nylon fiber, and rubber is the complex of filler, and this technical scheme is convenient to draw materials, and economizes on resources.
Described rigid rib frame is at least one steel pipe or the channel-section steel that are linked together by isolator, specifically two sections steel pipes can be formed by connecting by glass fiber spare; And be connected with fixture on steel pipe or the channel-section steel.So not only can rail be connected on the sleeper securely, and two sections steel pipes of mutually insulated or channel-section steel make rail arranged side by side separate on the transmission signal, do not disturb mutually, make this sleeper be more suitable for the construction of electrification railway by fixture.
The utility model mechanism is simple, and it is little to conduct oneself with dignity, and is easy to draw materials, and damping capaicty is strong, is particularly suited for the construction of electrification railway.
[description of drawings]
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a cross-sectional view of the present utility model.
Fig. 3 is the schematic diagram that two sections steel pipes of the present utility model connect.
[specific embodiment]
As shown in the figure, sleeper of the present utility model comprises elastic sleeper body 1, steel pipe muscle frame 2 and fixture: wherein two muscle framves 2 are all embedded in its pipe by insulating glass fiber 4 by two sections steel pipes and radially pass tube wall and glass fiber is formed by connecting with screw 3, can alleviate the deadweight of sleeper; The every steel pipe that links together is carried out placing as requested in the mould after the surfacing, with nylon fiber be grain, rubber be the complex of filler be coated on the structure that is cast into integral type on the muscle frame meet the shock-absorbing sleeper that the utility model requires.
According to concrete embodiment and requirement, can in advance on two steel pipe muscle framves fixedly trip bolt as the fixture 5 that connects rail; Also can after making the shock-absorbing sleeper in the above described manner, again fixture be connected on the sleeper.
Claims (5)
1, shock-absorbing sleeper comprises sleeper body (1) and the muscle frame (2) in it, it is characterized in that described muscle frame is the rigid rib frame, and described sleeper body is an elastic sleeper, the two cast solid.
2, shock-absorbing sleeper according to claim 1 is characterized in that described elastic sleeper body (1) for being grain with the nylon fiber, and rubber is the complex of filler.
3, shock-absorbing sleeper according to claim 1 and 2 is characterized in that described rigid rib frame (2) is at least one steel pipe or channel-section steel that is linked together by isolator (4).
4, shock-absorbing sleeper according to claim 3 is characterized in that described rigid rib frame (2) is that two sections steel pipes or channel-section steel are formed by connecting by the glass fibers part.
5, shock-absorbing sleeper according to claim 3 is characterized in that being connected with on described steel pipe or the channel-section steel fixture (5).
