Abstract
Description
Technical Field
[0001] The utility model relates to the field of concrete sleepers, in particular to a concrete sleeper which is convenient for fine adjustment. Background Art
[0002] Concrete sleepers are a structure used for laying rails. The sleepers not only support the rails, but also maintain their position, and also transfer the huge pressure transmitted by the rails to the roadbed. Compared with wooden sleepers, they have a long service life, high stability, and low maintenance workload. The damage rate and scrap rate are much lower than wooden sleepers. On seamless lines, the stability of reinforced concrete sleepers is an average of 15~20% higher than that of wooden sleepers. Therefore, they are particularly suitable for high-speed passenger lines.
[0003] The structure of the existing sleeper is generally simple, and a rail support part, a sleeper body and a ballast contact part are provided from top to bottom. The specific understanding can be referred to the invention patent with application number "CN202211579658.3". However, there are still some defects in the existing sleeper. Specifically, when installing rails on sleepers, the prior art generally uses mechanical equipment for laying, but mechanical laying cannot completely replace manual labor. After mechanical laying, on-site inspection is still required, and fixed structures are manually installed on both sides of the rails. Fine-tuning is required before installing the fixed structure. When fine-tuning is performed manually, workers usually lift the rails with a crowbar, and then adjust the position of the rails and the pads on the sleepers. When prying the rails, the parts of the existing sleepers where the rails are installed are horizontal, and after the rails are lowered, the gap between the bottom surface of the rails and the top surface of the sleepers is small. Therefore, it is difficult to insert the crowbar into the gap between the sleeper and the rail, which is time-consuming and laborious, and delays work efficiency. In order to solve this problem, the sleeper needs to be improved. Utility Model Content
[0004] The utility model aims to provide a sleeper with easy-to-adjust support height, so as to solve the problem that after the existing rails are laid on the sleepers, it is inconvenient to manually pry and fine-tune with a crowbar.
[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0006] A concrete sleeper that is easy to fine-tune includes a concrete sleeper body, a track support portion is provided on the top of the concrete sleeper body, the track support portion includes a left baffle seat installation position, a pad installation position and a right baffle seat installation position arranged in sequence from left to right, and the top of the side surface of the left baffle seat installation position and the top of the side surface of the right baffle seat installation position are both provided with a lifting rod insertion groove.
[0007] Lifting rod insertion grooves are provided on the side surfaces of the left baffle seat installation position and the right baffle seat installation position, so that it is convenient to insert the front end of the crowbar into the lifting rod insertion groove, and the lifting rod insertion groove extends inward to below the coverage range of the rail. When the rail is laid to the top surface of the concrete sleeper body and its position needs to be adjusted manually, the front end of the crowbar is inserted into the lifting rod insertion groove and then pressed down to pry up the rail for fine-tuning. Such insertion is easy and quick, and the fine-tuning of the rail can be completed more efficiently.
[0008] As a further preferred embodiment of the present invention, the tilting rod is inserted into the groove in a fan shape, and the inner end surface of the tilting rod inserted into the groove is a right-angle surface.
[0009] The inner end surface of the lifting rod inserted into the groove plays a supporting role after the front end of the crowbar is inserted.
[0010] As a further preferred embodiment of the present invention, a metal plate is provided on the arc-shaped supporting surface outside the groove where the tilting rod is inserted.
[0011] Because the arc-shaped supporting surface outside the groove where the lifting rod is inserted plays a supporting role when the crowbar lifts the rail, a metal plate is set on its surface to prevent it from being easily broken.
[0012] As a further preferred embodiment of the present invention, reinforcing ribs are provided in the concrete below the metal plate.
[0013] This provides better support strength.
[0014] As a further preferred embodiment of the present invention, a shock-absorbing pad is provided at the bottom of the concrete sleeper body.
[0015] Play a shock-absorbing role.
[0016] Compared with the prior art, the utility model can achieve at least one of the following beneficial effects:
[0017] 1. Lifting rod insertion grooves are provided on the side surfaces of the left baffle seat installation position and the right baffle seat installation position, so that it is convenient to insert the front end of the crowbar into the lifting rod insertion groove. The lifting rod insertion groove extends inward to below the coverage of the rail. When the rail is laid to the top surface of the concrete sleeper body and its position needs to be adjusted manually, the front end of the crowbar is inserted into the lifting rod insertion groove, and then pressed down to pry up the rail for fine-tuning. Such insertion is easy and quick, and can complete the fine-tuning of the rail more efficiently.
[0018] 2. The inner end surface of the lifting rod inserted into the groove plays a supporting role after the front end of the crowbar is inserted.
[0019] 3. Because the arc-shaped supporting surface outside the groove where the lifting rod is inserted plays a supporting role when the crowbar lifts the rail, a metal plate is set on its surface to prevent it from being easily broken.
[0020] 4. Better support strength. BRIEF DESCRIPTION OF THE DRAWINGS
