Description

Technical Field

[0001] The present invention relates to the technical field of power generation in thermal power plants, and in particular to a disassembly and assembly tool. Background Art

[0002] The steam turbine in a thermal power plant is a rotary steam power device. Its main function is to convert the thermal energy of high-temperature and high-pressure steam into mechanical energy. In the overall equipment configuration of a thermal power plant, the boiler, steam turbine and generator are collectively referred to as the three main equipment. The steam turbine speed probe in a thermal power plant is a key sensor used to monitor and control the speed of the steam turbine. In the steam turbine of a thermal power plant, the measurement and control of the speed is extremely important because it is directly related to the safety and stable operation of the unit. During the long-term high-speed operation of the steam turbine in a thermal power plant, there is a large vibration. The locking parts of the steam turbine speed probe (such as the locking nut) are prone to loosening and need to be tightened by staff.

[0003] In the related art, when tightening the locking part of the steam turbine speed probe, special disassembly and assembly tools are mostly used to perform the tightening operation. The existing disassembly and assembly tools require manual operation by the staff. Such a tightening method is cumbersome and complicated, and the tightening efficiency is relatively low. Moreover, when tightening, since the wrench needs to be inserted from the observation hole of the steam turbine front cover, a longer wrench is not convenient to insert, and a shorter wrench is not convenient to screw after insertion, which is time-consuming and laborious.

[0029] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0030] In the present disclosure, unless otherwise specified, “inside and outside” refer to the inside and outside of the corresponding component outline; in addition, it should be noted that the terms used, such as “first, second”, etc., are used to distinguish one element from another.

[0031] According to one embodiment of the present disclosure, Figure 1 , Figure 2 and Figure 3 As shown, a disassembly and assembly tool 100 is provided. The disassembly and assembly tool 100 may include a tightening wrench 1 and a gripping handle 2. The tightening wrench 1 may include a tightening shell 11 and a tightening assembly 12. The tightening shell 11 has an installation space 111, and a tightening opening 112 provided on the side wall of the tightening shell 11 and connected to the installation space 111. The tightening assembly 12 may include a first tightening gear 121 and a driving motor provided in the installation space 111 and drivingly connected to the first tightening gear 121. The first tightening gear 121 has a tightening groove 121a opposite to the tightening opening 112, and the tightening opening 112 is used for a locking member to pass through, so that the tightening groove 121a can be sleeved on the locking member, so as to drive the locking member to rotate under the drive of the driving motor. The gripping handle 2 is detachably connected to the tightening wrench 1, so that the angle between the gripping handle 2 and the tightening shell 11 can be adjusted.

[0032] In the technical solution provided by the embodiment of the present disclosure, the first tightening gear 121 is driven by a driving motor to rotate to realize the screwing and tightening operation of the locking member. Compared with the manual tightening method in the related art, it is reliable and convenient, simple to operate, and the tightening efficiency is effectively improved. It should be noted that for the tightening operation of the locking member, it is usually required that the tightening wrench 1 is inserted into the corresponding shell through the observation hole. In the technical solution of the present disclosure, the gripping handle 2 is detachably connected to the tightening wrench 1 so that the angle between the gripping handle 2 and the tightening shell 11 can be adjusted, so that the tightening wrench 1 can be inserted through the observation hole more conveniently, and the gripping handle 2 is convenient for people to hold, so that the disassembly and assembly process is more convenient and stable, thereby making the disassembly and assembly tool 100 better adaptable to various narrow space disassembly and assembly environments, and better adaptively adjusted according to the corresponding tightening environment to achieve better disassembly and assembly operations.

[0033] In some embodiments, Figure 3 As shown, the driving motor (not shown) has an output shaft 122. The output shaft 122 is connected to a driving gear 123 which is interconnected with the first fastening gear 121. The first fastening gear 121 is driven to rotate by the driving gear 123 to achieve the purpose of fastening the fastener. Such a setting method has a simple and reliable structure, low cost, and is easy to assemble.

[0034] In some embodiments, Figure 3 As shown, the fastening assembly 12 may further include a second fastening gear 124. The second fastening gear 124 is disposed in the installation space 111 and meshes with the driving gear 123 and the first fastening gear 121, respectively. The second fastening gear 124 and the first fastening gear 121 can form a multi-stage gear adjustment, and the provision of the second fastening gear 124 can improve the transmission efficiency of the gear transmission, and the transmission ratio is accurate, thereby making the internal structure of the entire fastening wrench 1 compact and reasonable.

[0035] In addition, in order to prevent the first fastening gear 121 from radially moving, an annular guide rail can be set on the inner wall of the fastening shell 11, and accordingly, an annular groove is set on the end face of the first fastening gear 121. Through the sliding fit between the annular guide rail and the annular groove, the first fastening gear 121 is guided to rotate to prevent radial moving.

[0036] In addition, the shape of the fastening groove 121a can be designed according to the actual application scenario. For example, when the locking member is a hexagonal nut, the fastening groove 121a can be designed as a hexagonal groove body to facilitate sleeve connection on the locking member. Of course, the fastening groove 121a can also be designed as, for example, a quadrilateral groove body, an octagonal groove body or other special-shaped groove bodies, etc., and the present disclosure does not make specific limitations on this.

[0037] In some embodiments, Figure 1 and Figure 2 As shown, the grip handle 2 includes a connecting member 21 and a gripping member 22. The gripping member 22 is detachably connected to the fastening housing 11 through the connecting member 21. The gripping member 22 can be configured as a gripping block, a gripping ball, a gripping hook, etc., which is not limited here, and those skilled in the art can make actual adjustments according to actual conditions. Optionally, an anti-slip rubber pad can be attached to the outer wall surface of the gripping member 22 to further improve the reliability of the disassembly and assembly tool 100.

[0038] In some embodiments, the connecting member 21 may be an L-shaped connecting rod. The connecting member 21 is configured as an L-shape, which can further improve the adaptability of the disassembly and assembly tool 100, so that the disassembly and assembly tool 100 can be adapted to more disassembly and assembly environments.

[0039] In some embodiments, Figure 1 and Figure 2 As shown, a mounting seat 114 having a first through hole 114a may be provided on the fastening shell 11. A connecting shaft 23 is provided on the connecting member 21. The connecting shaft 23 is detachably connected to the mounting seat 114 through a locking structure 3 and is inserted into the first through hole 114a with an adjustable rotation angle, so as to be able to adjust the angle between the gripping handle 2 and the fastening shell 11. The adjustable connection between the fastening shell 11 and the connecting member 21 is achieved through the connecting shaft 23 and the mounting seat 114. Such a setting method has a simple structure and is easy to assemble. Of course, those skilled in the art may also achieve the detachable connection between the fastening shell 11 and the connecting member 21 in other ways, which is not limited here, and those skilled in the art may make design adjustments according to actual conditions.
