Description

Technical Field

[0001] The utility model relates to the technical field of sleeper centering, and particularly relates to a centering device for sleepers. Background Art

[0002] A sleeper, also known as a crosstie, is also a kind of railway fitting. However, the materials used are not only wood, so it is more scientific to call it a sleeper. Despite its monotonous and unassuming appearance, the sleeper plays a very important role. The sleeper not only supports the rail, but also maintains the position of the rail, and further transmits the huge pressure transmitted by the rail to the roadbed. It must have a certain degree of flexibility and elasticity. It won't work if it's too hard, and it won't work if it's too soft. When a train passes by, it can deform appropriately to buffer the pressure, but it has to return to its original state as much as possible after the train passes.

[0003] Before installing bolts on the sleeper and pouring the bolt holes, centering is usually required to prevent the sleeper from being installed offset. The existing centering method is mainly manual centering, which has great limitations. Not only the accuracy cannot be guaranteed, but also a large amount of manpower is consumed. Therefore, a centering device for sleepers is proposed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a centering device for sleepers, which solves the problems mentioned in the above background art.

[0005] The utility model is realized as follows. A centering device for sleepers mainly consists of an installation groove, a transmission mechanism, a transmission plate, a movable plate and a centering plate. The transmission mechanism is arranged inside the installation groove. The transmission plate is arranged on the transmission mechanism. The movable plate is slidably connected to the transmission plate. The centering plate is fixedly installed at the bottom end of the movable plate.

[0006] A further technical solution of the utility model is that symmetrically distributed support frames are provided at both ends of the installation groove.

[0007] A further technical solution of the utility model is that the transmission mechanism includes a linear guide rail arranged inside the installation groove, a slider arranged on the linear guide rail, a bidirectional threaded rod arranged inside the installation groove, and a servo motor arranged at one end of the installation groove. The slider is slidably connected to the linear guide rail.

[0008] A further technical solution of the utility model is that both ends of the bidirectional threaded rod are rotatably connected to the installation groove, and the output end of the servo motor is fixedly connected to one end of the bidirectional threaded rod.

[0009] A further technical solution of the present utility model is that: threaded holes are provided on the transmission plate, and the transmission plate is threadedly connected to the bidirectional threaded rod through the threaded holes, and the top end of the transmission plate is fixedly connected to the slider.

[0010] A further technical solution of the present utility model is that: sliding grooves are provided at both ends of the movable plate, and the movable plate is slidably connected to the transmission plate through the sliding grooves.

[0011] A further technical solution of the present utility model is that: a mounting plate is provided on the transmission plate, and a connecting plate is provided on the movable plate.

[0012] A further technical solution of the present utility model is that: a telescopic rod is provided on the mounting plate, the top end of the telescopic rod is fixedly connected to the mounting plate, and the bottom end of the telescopic rod is fixedly connected to the connecting plate.

[0013] Advantages of the present utility model:

[0014] 1. Compared with manual centering, the present utility model controls the two transmission plates to move towards each other on the bidirectional threaded rod through the transmission mechanism, thereby driving the centering plate to move until the two symmetrical centering plates center the sleeper. Such a centering method is not only more accurate but also can effectively save a large amount of manpower.

[0023] Figures 1-4 The structural composition of a centering device for a sleeper is shown. The centering device for a sleeper mainly consists of an installation groove 2, a transmission mechanism 3, a transmission plate 4, a movable plate 5, and a centering plate 6. The transmission mechanism 3 is arranged inside the installation groove 2. The movable plate 5 is slidably connected to the transmission plate 4. The centering plate 6 is fixedly installed at the bottom end of the movable plate 5. There are two transmission plates 4, and they are symmetrically distributed on the transmission mechanism 3.

[0024] In this embodiment, support frames 1 are symmetrically arranged at both ends of the installation groove 2.

[0025] As Figure 2 shown, the transmission mechanism 3 is the main driving part in the present utility model. The transmission mechanism 3 includes: a linear guide rail 31 arranged inside the installation groove 2, a slider 32 arranged on the linear guide rail 31, a bidirectional threaded rod 33 arranged inside the installation groove 2, and a servo motor 34 arranged at one end of the installation groove 2. The slider 32 is slidably connected to the linear guide rail 31.

[0026] In this embodiment, both ends of the bidirectional threaded rod 33 are rotatably connected to the installation groove 2. The output end of the servo motor 34 is fixedly connected to one end of the bidirectional threaded rod 33. A threaded hole 41 is provided on the transmission plate 4. The transmission plate 4 is threadedly connected to the bidirectional threaded rod 33 through the threaded hole 41. The top end of the transmission plate 4 is fixedly connected to the slider 32.

[0027] When the servo motor 34 starts, it drives the bidirectional threaded rod 33 to rotate. Since the transmission plate 4 is threadedly connected to the bidirectional threaded rod 33 through the threaded hole 41, at this time, due to the driving force of the bidirectional threaded rod 33, the transmission plate 4 will move linearly on the linear guide 31 synchronously with the slider 32.

[0028] In this embodiment, sliding grooves 52 are provided at both ends of the movable plate 5, and the movable plate 5 is slidably connected to the transmission plate 4 through the sliding grooves 52.

[0029] In this embodiment, a mounting plate 42 is provided on the transmission plate 4, and a connecting plate 51 is provided on the movable plate 5.

[0030] In this embodiment, a telescopic rod 7 is provided on the mounting plate 42. The top end of the telescopic rod 7 is fixedly connected to the mounting plate 42, and the bottom end of the telescopic rod 7 is fixedly connected to the connecting plate 51.

[0031] As Figure 3 shown, the rod 7 controls the movable plate 5 to slide on the transmission plate 4 to select a suitable position for centering the sleeper, and at the same time can also meet the requirements of different terrain conditions.

[0032] It should be particularly noted that in this embodiment, the start and stop of the driving member servo motor 34 of the transmission mechanism 3 and the telescopic rod 7 (i.e., the control of each action) are completed by the controller, and the energy supply is provided by an external power supply. Among them, a SIMATIC type controller can be selected, and the power of the power supply should be greater than 500W.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
