Description

Technical Field

[0001] This utility model relates to the field of railway sleeper processing technology, and in particular to a tensioning device for sleeper processing. Background Technology

[0002] Current railway sleeper production lines involve setting up multiple sleeper slots within a long groove, placing reinforcing steel bars, and then pouring concrete. Each sleeper slot is separated by two insert plates. There are gaps between the insert plates and the slots that hold them in place. During production, the insert plates may become misaligned when inserted, necessitating a tensioning device between the two insert plates. Currently, there is no suitable tensioning device available. Utility Model Content

[0003] The main objective of this invention is to provide a tensioning device for railway sleeper processing, so as to effectively solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a tensioning device for sleeper processing, comprising a left support plate, a right support plate, and a conical screw. Both the left and right support plates are rectangular plates, each with 1 / 2 of an internally threaded cone fixed in the middle. The two internally threaded cones are fitted onto a conical screw.

[0005] Preferably, the left support plate has two guide shafts fixed to the outside of its threaded tapered sleeve, which are perpendicular to the left support plate, and the right support plate has two guide tubes at the corresponding positions of the guide shafts, with the guide shafts inserted into the guide tubes.

[0006] Preferably, a tension spring is installed at each of the four corners of the right support plate and the left support plate to tighten them.

[0007] Preferably, the tail of the conical screw has an external hexagonal head, which makes it easy to turn with a wrench.

[0008] The beneficial effects of this utility model are: simple structure, convenient operation, high efficiency and reliable effect. Attached Figure Description

[0012] Appendix Figure 4 This is a schematic diagram of the railway sleeper production line.

[0013] Appendix Figure 1-4In the middle, there is a right support plate 1, a conical screw 2, a tension spring 3, a left support plate 4, a guide shaft 5, a guide tube 6, an internally threaded conical sleeve 7, a tensioning device 8, a baffle 9, and a sleeper cement trough 10. Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] Appendix Figure 1-3 As shown, a tensioning device for sleeper processing includes a left support plate 4, a right support plate 1, and a conical screw 2. The left support plate 4 and the right support plate 1 are both rectangular plates, each with 1 / 2 of an internally threaded cone 7 fixed in the middle. The two internally threaded cones 7 are fastened to a conical screw 2.

[0016] The left support plate 4 has two guide shafts 5 fixed to the outside of its threaded tapered sleeve 7, which are perpendicular to the left support plate 4. The right support plate 1 has two guide tubes 6 at the corresponding positions of the guide shafts, and the guide shafts 5 are inserted into the guide tubes 6.

[0017] A tension spring 3 is installed at each of the four corners of the right support plate 1 and the left support plate 4 to tighten them.

[0018] The tail of the conical screw 2 has an external hexagonal head, which makes it easy to turn with a wrench.

[0019] See appendix Figure 4 During sleeper production, two insert plates 9 are inserted between the sleeper cement troughs 10. The two insert plates 9 are placed into the tensioning device 8 of this utility model. The outer hexagonal head at the tail of the conical screw 2 is tightened with a wrench, causing the right support plate 1 and the left support plate 4 to expand to both sides, thereby pressing the two insert plates 9 together and making them vertical. After placing steel bars in the sleeper cement trough 10, cement is poured. After solidification for a certain period of time, the conical screw 2 is reversed, and the tension spring causes the right support plate 1 and the left support plate 4 to contract inward. The tensioning device can then be removed.

[0020] Beneficial effects: This utility model has a simple structure, is easy to operate, has high efficiency, and reliable effect.

[0021] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
