[0033] The following is a more detailed description of the warning device for railway bridge engineering construction of the utility model in conjunction with the accompanying drawings and through specific implementation methods.

[0034] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0035] The warning device for railway bridge engineering construction of this embodiment is shown in FIG. Figure 1-Figure 6 The device can be installed in advance at the turnout and the rails that are more easily deformed before pre-operation after construction and before traffic use. When deformation occurs at the detection location, the warning component will touch the touch switch, and the alarm module will feedback to the control center. At the same time, the emergency support component will be activated to support the rails at that location to avoid causing greater losses. It includes a connecting plate 1, which is detachably connected to the waist of the rail. The connecting plate 1 is provided with a warning component 2, and the warning component 2 includes a contact module 21. The contact module 21 includes a contact plate 211, and the contact plate 211 contacts the bottom of the rail head. The bottom of the contact plate 211 is fixedly connected to a slide bar 212, and the slide bar 212 is sleeved with a sliding limit block 22 that is detachably fixed to the connecting plate 1. A matching block 23 that is detachably fixed to the connecting plate 1 is also provided below the sliding limit block 22, and a touch component 24 is provided between the contact module 21 and the matching block 23.

[0036] The touch assembly 24 includes a first rod 241, one end of which is hinged to the bottom of the slide bar 212, and the other end of which is hinged to a second rod 242. A touch rod 243 is also hinged to the outside of the hinged joint of the first rod 241 and the second rod 242, and a sleeve pad is provided at the front end of the touch rod 243. The other end of the second rod 242 is hinged to the matching block 23. A touch switch 25 that can abut against the touch assembly 24 is provided on the connecting plate 1. The sleeve pad can play a buffering role when hitting the touch switch 25, avoiding damage to the touch switch 25.

[0037] When deformation occurs at the detection location of the device, the contact module 21 moves downward to drive the touch rod 243 to move horizontally to touch the touch switch 25. The touch switch 25 is electrically connected to the alarm module, and the alarm module feeds back to the control center to remind the staff to handle it.

[0038] In order to strengthen the structure of the deformed part and reduce the deformation, in this embodiment, see Figure 2-Figure 5 The connecting plate 1 is also provided with an emergency support assembly 3, and the emergency support assembly 3 includes a base 31 and a support limit block 32. The base 31 is detachably fixedly arranged at the lower side of the connecting plate 1, and its bottom is detachably connected to the ground. The support limit block 32 is detachably fixedly connected to the connecting plate 1.

[0039] The emergency support assembly 3 also includes a starting assembly 33, which includes a connecting rod 331, one end of which is hinged to the touch rod 243, and the other end of which is movably inserted into the support limit block 32, so that the starting assembly 33 can be easily replaced. An arc plate 332 is welded on the surface of the connecting rod 331, and a slider 333 is welded on the other end of the arc plate 332. A second baffle 36 welded to the base 31 is closely arranged on the other side of the slider 333. A locking module is arranged inside the second baffle 36, and the locking module includes a rectangular block 361, which is arranged in the slide groove of the second baffle 36 at the upper end of the first connecting portion 3331 of the slider 333. A spring 362 is arranged between the slide groove of the second baffle 36 and the rectangular block 361. Under normal conditions, the spring 362 is in a compressed state.

[0040] The first connection portion 3331 of the slider 333 is slidably connected to the second baffle 36, and the second baffle 36 is vertically provided with a first baffle 35 welded to the base 31. A support block 34 is provided between the first baffle 35, the second baffle 36 and the slider 333, and the bottom of the support block 34 is placed on the slider 333 and the second connection portion 341 on one side thereof is slidably connected to the first baffle 35.

[0041] See also Figure 6 The slider 333 also includes an angled portion 3332, which is an arc-shaped structure, so that the connecting rod 331 can drive the slider 333 to move. A limiting portion 3333 is also integrally provided on the top of the slider 333, which can further constrain the position of the support block 34 so that it can better play a supporting role.

[0042] The working principle of the warning device for railway bridge engineering construction of the utility model is as follows: before pre-operation after construction and before traffic use, it is set in advance at the branch and the rails that are more easily deformed. When deformation occurs at the detection point of the device, the contact module 21 moves downward to drive the touch rod 243 to move horizontally to touch the touch switch 25. The touch switch 25 is electrically connected to the alarm module, and the alarm module feeds back to the control center to remind the staff to handle it.

[0043] When the touch rod 243 moves laterally to touch the touch switch 25, the touch rod 243 will also drive the subsequent starting assembly 33 to move in the same direction, so that the slider 333 moves toward the support block 34, and the bottom of the support block 34 quickly moves upward, and its top quickly resists the bottom of the rail head. At the same time, the spring 362 in the second baffle 36 rebounds and drives the rectangular block 361 to move downward, so that the first connecting portion 3331 of the slider 333 is locked, and then the slider 333 is locked. The limit portion 3333 at the top of the slider 333 further constrains the support block 34 that moves upward for emergency support.
