DETAILED DESCRIPTION

[0030] The technical scheme in the embodiment of the utility model will be described clearly and completely in the embodiment of the utility model in combination with the drawings. The embodiment described below is exemplary, and is only used to explain the utility model, and can not be understood as the limitation of the utility model.

[0031] A railway track fastener protection device, as shown in Figures 1-4 The track fastener 1 and the track 2 are provided with the protective device 3, the protective device 3 includes the protective shell 301, the top of the protective shell 301 is provided with the sealing mechanism 4, the sealing mechanism 4 includes the waterproof cloth 401, the top of the waterproof cloth 401 is provided with the through -hole 402, the front and rear ends of the waterproof cloth 401 are provided with the cloth curtain 403, the inner side of the waterproof cloth 401 is provided with the rubber surface 405, and the rubber surface 405 is adhered to the protective shell 301, in the use process, the rubber surface 405 of the waterproof cloth 401 is tightly adhered to the top of the protective shell 301. At this time, the rubber surface 405 in the inner side is tightly adhered to the protective shell 301, so that effective fixation is realized. At the same time, when adhering, it is necessary to ensure that the through -hole 402 can effectively expose the pinch part 303, to avoid affecting the normal use of the protective device 3.

[0032] Referring to Figure 1 , Figure 2 , the cloth curtain 403 is provided with a rubber strip 404 at the split curtain, and since the inner side of the cloth curtain 403 is not provided with a rubber surface 405, the cloth curtain 403 can be effectively wrapped on the track 2 during use, and the rubber strip 404 is used for butt joint and adhesion, so as to effectively prevent impurities such as mortar from splashing onto the protective shell 301.

[0033] Referring to Figure 1 , Figure 4 , the inner side edge of the protective shell 301 is provided with a sealing strip 304, the sealing strip 304 abuts with the track 2 and the base, and since the protective cover in the traditional protection device is consistent with the shape of the track and the fastener, there may be a small gap at the contact edge of the track 2 and the base. These gaps may cause leakage. Therefore, by adding the sealing strip 304, the sealing strip 304 is tightly fitted at the contact edge of the protective shell 301, the track 2 and the base, which effectively prevents the leakage of the mortar, thereby ensuring the absolute cleanliness and safety of the track fastener 1 during construction. At the same time, the sealing strip 304 can also avoid metal friction between the protective shell 301 and the track 2, which can cause damage to the protective shell 301 and the track 2.

[0034] Referring to Figure 3 , Figure 4 , the protective shell 301 is divided into two shells, and the two shells are connected by a bolt dismounting connecting clamp 302. The protective device 3 connected by the bolt dismounting connecting clamp 302 is easy to install and dismount, which is convenient for maintenance and replacement of the protective device 3.

[0035] Referring to Figure 1 , Figure 2 , the top of the clamp 302 is provided with a reinforcing piece 305, and the reinforcing piece 305 is provided with two arc-shaped structures. Since the plastic deformation or fatigue of the material of the clamp 302 after repeated bending may cause deformation that cannot be completely reset, the reinforcing piece 305 provides additional support, reduces the permanent deformation of the clamp 302 caused by repeated bending, and makes the clamp 302 still maintain good clamping force and shape after repeated use. At the same time, the arc-shaped structure design of the reinforcing piece 305 can more evenly distribute the clamping force, avoid excessive stress concentration at a specific position of the clamp 302, and thus improve the durability and reliability of the clamp 302.

[0036] Referring to Figure 3 , Figure 4 , the track 2 is installed on the top of the track base, and the track fastener 1 is arranged on both sides of the track 2, so that the fastener 1 can effectively fix the track 2.

[0037] Referring to Figure 1 , Figure 4The two sides of the clamping piece 302 are provided with pinch portions 303, the pinch portions 303 are made of spring steel wires, so that the pinch portions 303 can be more conveniently pinched to operate when the protection device 3 is installed or dismounted. The material of the spring steel wires makes the pinch portions 303 have certain elasticity and toughness, so that the pinch operation can be conveniently performed, and deformation or damage due to external force in the use process can be avoided.

[0038] Referring to Figure 1 、 Figure 3 The two pinch portions 303 are provided in a mirror image along the central axis of the clamping piece 302, so that the two pinch portions 303 can be more stably pinched to operate when the protection device 3 is installed or dismounted. At the same time, the mirror image setting also makes the protection device 3 more beautiful and symmetrical in appearance.

[0039] The implementation principle of the embodiment is that: first, the split shells of the two protection shells 301 are fixedly connected with the clamping piece 302 through bolts, then the waterproof cloth 401 is adhered to the protection shell 301 through a glue surface, and it is ensured that the curtain 403 is in a loosened state, then the curtain 403 is wrapped around the track 2, and the curtain is adhered to the track by using the adhesive tape 404, and the end of the curtain needs to be tightly closed, so as to ensure that the curtain 403 is wrapped and fixed on the track 2.

[0040] After the track bed concrete pouring construction is completed, the construction personnel need to pull the curtain with force by hand, at this time the adhesive tape will be loosened, then the two pinch portions at the top of the protection device can be found, and the two pinch portions are pinched by two hands respectively, at this time the protection shell will have a tendency to be turned outwards, and when the protection shell is completely turned outwards, the railway track fastener protection device can be quickly and effectively removed, when the sealing mechanism 4 needs to be replaced, the waterproof cloth can be torn off by hand, and then a new sealing mechanism 4 can be replaced.

[0041] Although the embodiments of the utility model have been shown and described, the specific embodiments are only an explanation of the utility model, and are not a limitation of the utility model, and the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner, and the person skilled in the art can make non-creative modification, replacement and change of the embodiments according to the needs after reading the specification without departing from the principles and purposes of the utility model, but as long as it is within the scope of the claims of the utility model, it is protected by the patent law.
