Description

Technical Field

[0001] The utility model relates to the technical field of concrete sleepers, and particularly relates to a concrete sleeper facilitating the installation of tracks. Background Art

[0002] In the construction of ballast tracks, concrete sleepers have basically replaced wooden sleepers. Due to the unique mechanical properties and wind and rain resistance characteristics of concrete sleepers, they have been widely used.

[0003] When installing tracks with concrete sleepers, generally, a track installation vehicle is first used to arrange the sleepers at equal intervals, and then rubber pads are manually placed on the sleepers. The track installation vehicle then continues to lay the rails from the rear end onto the sleepers. Finally, the staff adjusts the position of the rails on the sleepers and fixes the rails. Generally, the process of manually placing rubber pads in the middle is carried out synchronously during the movement of the track installation vehicle. If the track installation vehicle needs to work continuously, the staff needs to complete the placement of rubber pads within the limited reserved time. Therefore, it is very easy for the rubber pads to be placed obliquely during the placement process, and the position of the rubber pads needs to be adjusted by the subsequent staff when fine-tuning the track, which is relatively inconvenient; and the placement is generally carried out under the track installation vehicle. Although the moving speed of the track installation vehicle is slow, there is still a certain degree of danger.

[0004] At the same time, the gap between the rubber pad and the sleeper is prone to water accumulation on rainy days. The long-term water accumulation makes the rain water easily corrode the sleeper to a certain extent, affecting the service life of the sleeper. Content of the Utility Model

[0005] Purpose of the utility model: In order to overcome the problems existing in the prior art, the utility model provides a concrete sleeper facilitating the installation of tracks, directly fixing the rubber pad on the track installation surface, so that when installing the track, there is no need to manually place the rubber pads one by one. The pre-fixed rubber pads only need to be fixed by the production line during the production process of the sleepers. Compared with placing during the laying process, the efficiency is faster, more labor is saved, and its position is more accurate, avoiding the situation of subsequent manual adjustment.

[0006] To solve the above problems, the utility model adopts the following technical solutions:

[0007] A concrete sleeper facilitating the installation of tracks, including a sleeper body. At both ends of the sleeper body, there are provided rail bearing platforms for installing rails. The rail bearing platform includes a middle track installation surface and fixed component installation surfaces on both sides of the track installation surface. A rubber pad is fixed in the middle of the track installation surface, and spike reserved holes are provided on the fixed component installation surfaces.

[0008] Preferably, the track installation surface protrudes upward from the rail bearing platform.

[0009] Preferably, the rail mounting surface is a trapezoidal boss that is narrower at the top and wider at the bottom.

[0010] Preferably, the rubber cushion extends to the inclined side surface of the rail mounting surface.

[0011] Preferably, the middle of the mounting surface of the fixing component is a platform surface for facilitating the installation of the fixing component, and the front and rear sides are downward inclined surfaces for facilitating drainage. The spike reserved holes are arranged on the platform surface.

[0012] Preferably, a drainage slope is provided at the top edge of the sleeper body.

[0013] Preferably, a rubber cushion is fixed to the middle of the rail mounting surface with glue.

[0014] Preferably, anti-slip nails are provided downward at the bottom of the sleeper body.

[0015] Preferably, a groove is provided with a downward depression in the middle of the sleeper body, and the cross-section of the groove is a trapezoid that is wider at the top and narrower at the bottom.

[0016] Beneficial effects: Compared with the prior art, the present utility model has the following advantages:

[0017] 1. The rubber cushion is directly fixed on the rail mounting surface, so that when installing the rail, there is no need to place the rubber cushion piece by piece manually. The pre-fixed rubber cushion only needs to be fixed by the production line during the production process of the railway sleeper. Compared with placing it during the laying process, the efficiency is faster, more labor is saved, and its position is more accurate, avoiding the situation of subsequent manual adjustment.

[0018] 2. The rail mounting surface protrudes upward from the rail bearing platform and is a trapezoidal boss that is narrower at the top and wider at the bottom. The rubber cushion extends to the inclined side surface of the rail mounting surface, which can prevent rainwater from entering the gap between the rubber cushion and the railway sleeper, and prevent the railway sleeper from being corroded by long-term accumulation of rainwater.

[0025] All features disclosed in this specification, or all steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any manner.

[0026] Any feature disclosed in this specification (including any additional claims, abstract, and drawings) can be replaced by other equivalent or similar-purpose alternative features unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is only an example of a series of equivalent or similar features.

[0027] As Figures 1-5 As shown, a concrete sleeper for facilitating the installation of rails includes a sleeper body 1. At both ends of the sleeper body 1, there are provided rail supports 2 for installing rails. The rail support 2 includes an intermediate rail installation surface 21 and fixing component installation surfaces 22 on both sides of the rail installation surface 21. A rubber pad 3 is fixed in the middle of the rail installation surface 21, and spike reserved holes 4 are provided on the fixing component installation surface 22.

[0028] For the concrete sleeper with this structure, the rubber pad is directly fixed on the rail installation surface, so that when installing the rails, there is no need to place the rubber pads one by one manually. The pre-fixed rubber pads only need to be fixed by the production line during the production of the sleepers. Compared with placing them during the laying process, the efficiency is faster, more labor is saved, and their positions are more accurate, avoiding the situation of subsequent manual adjustment.

[0029] In this embodiment, the rail installation surface 21 protrudes upward from the rail support 2.

[0030] In this embodiment, the rail installation surface 21 is a trapezoidal convex platform with a narrower upper part and a wider lower part.

[0031] In this embodiment, the rubber pad 3 extends to the inclined side surface of the rail installation surface 21.

[0032] Adopting the above structure can prevent rainwater from entering the gap between the rubber pad and the sleeper, and prevent the corrosion of the sleeper caused by the accumulated rainwater over a long time.

[0033] In this embodiment, the middle of the fixing component installation surface 22 is a platform surface 221 for facilitating the installation of the fixing components, and the front and rear sides are downward inclined surfaces 222 for facilitating drainage. The spike reserved holes 4 are provided on the platform surface.

[0034] In this embodiment, a drainage slope 11 is provided at the top edge of the sleeper body 1, which can effectively drain the rainwater on the sleeper and prevent the corrosion of the sleeper caused by long-term water accumulation.

[0035] In this embodiment, a rubber cushion plate 3 is fixed to the middle of the track installation surface 21 with glue. The glue can quickly fix the rubber cushion plate, and at the same time, the glue can fill the gap between the rubber cushion plate and the track installation surface to prevent rainwater from entering.

[0036] In this embodiment, anti-slip nails 5 are provided downward at the bottom of the sleeper body 1. The anti-slip nails are embedded in the ballast during the laying process, which can reduce the influence of the forces in all directions during the train operation on the position of the sleeper and prevent the sleeper from shifting during long-term use.

[0037] In this embodiment, a groove 12 is provided by recessing downward in the middle of the sleeper body 1. The cross-section of the groove 12 is a trapezoid with a wider upper part and a narrower lower part. With this structure, the middle of the sleeper can withstand more lateral forces while reducing the consumption of materials for the sleeper.

[0038] As Figure 5 shown, it is a sectional view of the sleeper of the present utility model after installing the track. Only by arranging the tracks at equal intervals through the sleeper arranging device of the track installation vehicle, and then laying the rails on the sleepers through the rail laying device on the track installation vehicle, the staff only needs to fix the rails and sleepers through the fixing components at the back.

[0039] The purpose of the above embodiments is to exemplarily reproduce and deduce the technical solutions of the present utility model, and to completely describe the technical solutions, purposes and effects of the present utility model. The purpose is to make the public understand the disclosed content of the present utility model more thoroughly and comprehensively, and it does not limit the protection scope of the present utility model.

[0040] The above embodiments are not an exhaustive list based on the present utility model. In addition, there may be multiple other embodiments not listed. Any replacement and improvement made on the basis of not violating the concept of the present utility model fall within the protection scope of the present utility model.
