Description

Technical Field

[0001] The utility model relates to a special rail pulling clamp for rail pulling operation required by railway engineering departments, in particular to a movable rail clamp with a safety lock buckle. Background Art

[0002] When replacing seamless rails, railway engineering departments often need to pull rails. The existing technology is to use movable rail clips to pull long rails. However, the existing movable rail clips do not have safety locks and often come off during use. Especially when pulling rails on curves, the movable rail clips are more likely to come off, seriously endangering equipment and personal safety. Utility Model Content

[0003] The utility model aims to prevent the movable rail clamp from being disengaged when dragging a long rail, thereby harming personnel and affecting work efficiency. In view of the shortcomings of the prior art, the utility model provides an movable rail clamp with a safety lock buckle.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a movable rail card with a safety lock comprises a round lock 1, an inclined wedge 2, a cotter pin 3, a left rail card 5, a right rail card 6, a safety lock 7, and a steel wire rope 8. The inclined wedge 2 is a slope with one end high and the other end low, and a pulling hole 10 for passing the steel wire rope 8 is provided at the lower end. The inclined wedge 2 is respectively clamped with the rail surface and the inner layer of the movable rail card body. The movable rail card body is two left and right C-shaped rail card, the left rail card 5 is connected with the right rail card 6 by the round lock 1, the top of the left rail card 5 is provided with a hinge and is hinged with the safety lock 7, and the top of the right rail card 6 is provided with a buckle groove 9. When the safety lock 7 is closed, it can be inserted into the buckle groove 9 and position the movable rail card body so that it will not expand when dragging and pulling the long steel rail.

[0005] A further technical solution of the utility model is that the inner layer of the movable rail card is a slope with one end being high and the other end being low, and the slope of the inner layer of the movable rail card is matched and connected with the inclined wedge.

[0006] The working process and advantages of the utility model are as follows: when it is necessary to drag and pull a long steel rail, put the movable rail card on the rail head, insert the inclined wedge, install the inclined wedge tightly with the rail surface and the movable rail card, and close the safety lock. Start the winch, and the long steel rail can be dragged and pulled; because the inclined wedge is an inclined surface that matches the contact surface of the movable rail card, when there is a straight line pulling force, the movable rail card and the rail are pulled tighter and tighter, so that the long steel rail can be dragged and pulled. If the rail is bent upward, an F3 tension will appear. The movable rail card is designed with a safety lock. Since the safety lock is buckled into the groove at the top of the movable rail card body, the movable rail card body is limited and cannot be opened, so that the movable rail card is prevented from expanding. The utility model can prevent the movable rail card from being disengaged when dragging a long steel rail, which may injure personnel and affect work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The following will combine the accompanying drawings of the utility model to clearly and completely describe the technical scheme in the embodiment of the utility model. A movable rail card with a safety lock comprises a round lock 1, an oblique wedge 2, a cotter pin 3, a long steel 4, a left rail card 5, a right rail card 6, a safety lock iron 7, and a wire rope 8. The oblique wedge 2 is a slope with one end high and the other end low, and a pulling hole 10 for passing the wire rope 8 is provided at the lower end. The oblique wedge 2 is clamped with the rail surface and the inner layer of the movable rail card body respectively. The movable rail card body is two left and right C-shaped rail cards. The left rail card 5 is connected to the right rail card 6 through a round lock 1. The inner layer of the movable rail card is a slope with one end high and the other end low. The slope of the inner layer of the movable rail card is connected to the oblique wedge. The top of the left rail card 5 is provided with a hinge and is hinged to the safety lock iron 7. The top of the right rail card 6 is provided with a buckle groove 9. When the safety lock iron 7 is closed, it can be inserted into the buckle groove 9, and the movable rail card body is positioned so that it will not expand when dragging and traction long steel rails.
