Description

TECHNICAL FIELD

[0001] The utility model relates to railway device technical field, and specifically point to a convenient to detach frozen clamp plate. BACKGROUND

[0002] The frozen clamp plate commonly used in the current railway track is fixed on the rail joint by high-strength bolts to realize the freezing of the rail joint, and its function is to ensure that the rail joint can still maintain stable connection when the temperature changes. When the traditional frozen clamp plate needs to be disassembled, external force such as hammering and crowbar is usually used to forcibly separate the clamp plate and the rail, and this operation method has the following defects: it is easy to cause mechanical damage to the contact surface of the clamp plate and the rail, affecting the subsequent use performance; the disassembly process is time-consuming and laborious, and the working efficiency is low; repeated external force impact can cause stress concentration in the clamp plate, shortening the service life, therefore, designing a convenient to detach frozen clamp plate is an urgent problem for the technical personnel in the related field. SUMMARY

[0003] To solve the above technical problems, the technical scheme provided by the utility model is: a convenient to detach frozen clamp plate, which comprises a frozen clamp plate body, a plurality of screw holes are arranged on the frozen clamp plate body at intervals, a top opening bolt is detachably connected in the screw hole, and an external thread corresponding to the thread in the screw hole is arranged outside the top opening bolt.

[0004] Preferably, the length of the top opening bolt is greater than the thickness of the frozen clamp plate body.

[0005] Preferably, the top opening bolt comprises a threaded rod portion mounted in the screw hole and a bolt head portion arranged on the outer surface of the frozen clamp plate.

[0006] Compared with the prior art, the utility model has the advantages that the utility model replaces the traditional hammering mode by the threaded transmission of the top opening bolt, avoids the mechanical damage of external force impact to the contact surface of the clamp plate and the rail, ensures the repeated use of the equipment, and is convenient to operate, which can improve the working efficiency.

[0009] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0010] In the description of the embodiments of this utility model, it should be noted that if terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," or "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and "third" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0011] Furthermore, the use of terms such as "horizontal," "vertical," and "sag" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0012] In the description of the embodiments of this utility model, "a plurality of" means at least two.

[0013] In the description of the embodiments of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0014] Example:

[0015] A easily disassembled freezing clamp includes a freezing clamp body 1. Several threaded holes 2 are spaced apart on the freezing clamp body 1. A detachable opening bolt 3 is detachably connected to each threaded hole 2. The opening bolt 3 has an external thread corresponding to the internal thread of the threaded hole 2. The length of the opening bolt 3 is greater than the thickness of the freezing clamp body 1. The opening bolt 3 includes a threaded shank 301 installed in the threaded hole 2 and a bolt head 302 disposed on the outer surface of the freezing clamp.

[0016] In practice, the jacking bolt is screwed into the end of the frozen clamp body that needs to be disassembled. The threaded transmission causes the jacking bolt to apply force to the rail, thereby separating the frozen clamp body from the rail. The jacking bolt 3 is made of high-strength materials, such as low-carbon alloy steel, medium-carbon steel, and high-strength low-alloy steel.

[0017] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
