[0029] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The utility model provides a turbine oil cylinder quick installation and disassembly tooling device, that is, a device for realizing quick installation and disassembly of oil cylinders. It mainly realizes efficient disassembly and installation of the servo oil cylinders in the middle and lower parts of TRT turbines. Under the premise of no modification on site and no installation of lifting tools, this device can realize the loading and unloading of oil cylinders by a single person.

[0031] like Figure 1-7As shown, a turbine cylinder quick installation and disassembly tooling device of the utility model is mainly composed of an end cover 1, a rotary hinge 2, a bracket 3, a clamping device 4, etc., and is connected to the box body of the TRT turbine belly through multiple positioning bolt holes 1-1 on the end cover 1 and multiple end cover bolts to achieve overall fixation of the device. The device is divided into an upper and lower part, the upper part is composed of the end cover 1, and is connected to the turbine through multiple positioning bolt holes 1-1 and multiple end cover bolts around the end cover 1. The device is fixed with the rotary hinge 2 as the interface as the lower part, and the lower part is composed of the bracket 3. Two clamping devices 4 are arranged on the bracket 3, and the two clamping devices 4 are respectively installed on the upper and lower sides of the bracket 3. After the device is in place, the inner sides of the two clamping devices 4 are in contact with the servo cylinder 6, and the servo cylinder 6 is clamped and fixed on the bracket 3, so that the servo cylinder 6 can be quickly positioned, and the servo cylinder 6 is fixed by the clamping device 4. The servo cylinder 6 is moved within a certain angle by the rotation of the rotary hinge 2.

[0032] The clamping device 4 includes a fixed clamp 41 and a movable clamp 42. The fixed clamp 41 is welded to the bracket 3. One end of the movable clamp 42 is rotatably connected to one side of the fixed clamp 41 through a positioning hinge 43, and the other end is used for locking connection with the other side of the fixed clamp 41; the movable clamp 42 flips around the positioning hinge 43.

[0033] The fixed clamp 41 and the movable clamp 42 are both semicircular structures. When the fixed clamp 41 and the movable clamp 42 are closed, they form a circular clamp, and the fixed clamp 41 and the movable clamp 42 are symmetrically arranged when closed.

[0034] One end of the movable clamp 42 is fixed to the bracket 3 by a positioning hinge 43 and can be turned freely, and the other end is processed with a first bolt hole for fixing the servo cylinder 6. The other side of the fixed clamp 41 is processed with a second bolt hole, and the first bolt hole is connected to the second bolt hole by a fastening bolt and a nut to achieve locking and opening between the movable clamp 42 and the fixed clamp 41. For easy fastening, the connecting nut of the fastening bolt adopts a butterfly nut.

[0035] The size and shape of the bracket 3 and the clamp are made according to the shape and size of the servo cylinder 6. First, open the clamping device 4 and put the servo cylinder 6 into the bracket 3, and position the servo cylinder 6 through the bracket 3, the inclined surface of the diameter-changing part of the servo cylinder 6 and the top of the bracket 3. After positioning, turn over and close the clamping device 4 to clamp the servo cylinder 6.

[0036] Two circular clamps with central through holes are welded on the bracket 3. The size of the central through holes is consistent with the outer diameter of the servo oil cylinder 6. Each circular clamp is divided into two petals. One petal of the clamp (i.e., the fixed clamp 41) is fixedly welded to the bracket 3, and the other petal of the clamp (i.e., the movable clamp 42) is symmetrically fixed to the bracket 3 through the positioning hinge 43. The two petals of the clamp are combined into a full circle by tightening bolts to fix the servo oil cylinder 6 (the circumference of the clamping device clamp is reduced by 2mm to ensure the clamping force).

[0037] The bracket 3 rotates around the rotary hinge 2. First, the servo cylinder 6 is clamped and fixed by the clamping device 4. Then, the connecting bolts between the servo cylinder 6 and the TRT turbine are removed. Then, the servo cylinder 6 is rotated around the rotary hinge 2 by the bracket 3.

[0038] A lifting ring 5 is welded to the bottom of the bracket 3, and the bracket 3 is rotated by a hand winch.

[0039] The end cover 1 is a hollow frame structure made of steel plate, that is, it is made of steel plate as a whole and is hollow to reduce weight. The first hinge hole is welded at the bottom of the end cover 1, and the first hinge hole is connected to the rotary hinge 2 for connecting the bracket 3. The positioning bolt holes 1-1 are evenly distributed around the end cover 1. The end cover 1 is fixed to the square base of the oil cylinder on the turbine casing (the box body on the belly of the TRT turbine) through the positioning bolt holes 1-1 and the end cover bolts.

[0040] The bracket 3 is made of steel plates, and the size and shape of the stepped slope are consistent with the outer dimensions of the servo cylinder 6. The upper part of the bracket 3 is welded with a second hinge hole connected to the rotary hinge 2 for connecting the end cover 1. The bracket 3 can be composed of a bracket body structure and a clamping device 4.

[0041] Compared with the existing operation mode, the device of the present invention can realize the rapid completion of the disassembly tooling of the servo oil cylinder, greatly reducing the maintenance operation time of the servo oil cylinder, while improving the installation accuracy and improving the maintenance quality of the servo oil cylinder.

[0042] During routine maintenance of the TRT generator set cylinder, due to limited site space and equipment, disassembly is difficult. The utility model device can be used to efficiently and quickly disassemble the turbine cylinder, thereby further reducing the disassembly and maintenance time of the cylinder.

[0043] Finally, 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 aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
