DETAILED DESCRIPTION

[0020] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0023] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0024] Example 1

[0025] Reference Figure 1 to Figure 4 The present embodiment provides a magnetostrictive protection device, including an outer sleeve 100, an inner rod 101 is arranged inside the outer sleeve 100, one end of the inner rod 101 is slidably connected to the outer sleeve 100, and a hanging ring 102 is arranged at the other end of the inner rod 101, and the hanging ring 102 is connected to the inner rod 101 through a threaded rod 103; a cooling bin 104 is arranged at the end of the outer sleeve 100, and an end cover 105 is fixed to the end of the cooling bin 104.

[0026] In this embodiment, the inner rod 101 can telescopically move in the outer sleeve 100. The outer sleeve 100 and the inner rod 101 are components that are sleeved on the outside of the magnetostrictive sensor for protection. The end of the inner rod 101 is fixed to the magnetic ring, and the hanging ring 102 on the inner rod 101 is connected to the moving part to be measured. During the movement, the magnetic ring is driven to move to achieve the purpose of measuring the moving distance. The measurement principle of magnetostriction will not be repeated.

[0027] An air pipe is provided at the end of the cooling chamber 104 for passing compressed air to cool the sensor to adapt to the high temperature environment.

[0028] A truncated cone 105 a is disposed on the end cover 105 , and a circular groove 105 b is disposed at the bottom of the truncated cone 105 a .

[0029] A synchronous member 106 is sleeved on the outer side of the truncated table 105 a , and arc teeth 106 a are arranged on the outer side of the synchronous member 106 .

[0030] Specifically, the length of the arc tooth 106a is set according to the specific factors. The factors to be considered may include the length of the bolt 107, the number of threads thereon, the pitch parameters, and the outer diameter and number of teeth of the transfer member 108. The specific relationship is the basis of mechanical design and will not be repeated. What needs to be ensured is that the number of teeth on the arc tooth 106a is sufficient to screw out the bolt 107.

[0031] The end cover 105 is connected to the cooling chamber 104 via bolts 107 .

[0032] Specifically, a ring plate 106b is disposed inside the ring plate 106, and the ring plate 106b is embedded in the circular groove 105b. This structure limits the synchronous member 106 so that the synchronous member 106 can only rotate outside the truncated table 105a.

[0033] The device further comprises a transfer member 108, wherein the transfer member 108 comprises a gear ring 108a, and a hexagonal hole 108b is arranged in the middle of the gear ring 108a.

[0034] The gear ring 108a meshes with the arc teeth 106a. When disassembly is required, the gear ring 108a is sleeved on the bolts 107. In this embodiment, four bolts are used as an example, and the gear ring 108a is placed on three bolts.

[0035] The rotating member 109 is also included. The rotating member 109 is a handle 109 a added to the outside of the transfer member 108 .

[0036] The screwing piece 109 is used for neatly driving the disassembly. Specifically, the screwing piece 109 is inserted into the remaining bolts 107, and the handle 109a is turned. The screwing piece 109 drives the synchronous piece 106 to rotate, and the synchronous piece 106 drives the remaining transfer pieces 108 to rotate, so that each bolt 107 is disassembled synchronously to improve efficiency.

[0037] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
