Description

Technical Field

[0001] The invention relates to the technical field of oil motor disassembly, and in particular to oil motor safe disassembly and assembly auxiliary equipment. Background Art

[0002] Existing thermal power plants generally use oil motors as actuators for regulating steam valves. Oil motors are used to adjust the valve opening to control the steam intake of the turbine and achieve changes in power generation load. The operation of the oil motor has a great impact on the stability of the system, so it is necessary to maintain the oil motor during the overhaul period.

[0003] The oil motor is usually fixed to the steam turbine valve and regulating valve with bolts, and the oil motor is usually disassembled and assembled by manual labor. However, when disassembling and assembling the oil motor, the disc spring in the oil motor operating seat is under pressure for a long time. If the disc spring suddenly loses force when disassembling and assembling the bolts, the impact force will cause the oil motor to bounce outward as a whole, causing personal injury to the operator. In addition, when disassembling and assembling the oil motor, the torque cannot be accurately controlled when disassembling the nuts manually, which will cause inconsistent pre-tightening torques of different bolts, resulting in quality problems such as opening of the connection surface between the oil motor and the steam valve. Summary of the invention

[0005] Therefore, the present invention provides a safe disassembly and assembly auxiliary equipment for a hydraulic motor, the purpose of which is to solve the problem that the hydraulic motor is usually disassembled and assembled by manual labor. However, in this method, when the hydraulic motor is disassembled and assembled, the disc spring in the hydraulic motor operating seat is in a compressed state for a long time. When the bolts are disassembled and assembled, if the disc spring suddenly releases force, the impact force will bounce the entire hydraulic motor outward, causing personal injury to the operator. In addition, when the hydraulic motor is disassembled and assembled, the torque cannot be accurately controlled when the nuts are disassembled and assembled manually, which will cause inconsistent pre-tightening torques of different bolts, thereby leading to quality problems such as opening of the connection surface between the hydraulic motor and the valve.

[0007] The hydraulic motor unit comprises a limit assembly arranged on the hydraulic motor body;

[0008] The anti-recoil limiting unit is arranged between the fixing component and the limiting component to prevent a sudden relative displacement between the fixing component and the limiting component.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] 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.

[0030] 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 is it an embodiment that is mutually exclusive with other embodiments, either individually or selectively.

[0031] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, 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.

[0032] Example 1, reference Figure 1 - Figure 8 , which is the first embodiment of the present invention, provides a hydraulic motor safe disassembly and assembly auxiliary device, the device comprising: a steam turbine unit 100, comprising a fixing assembly 102 disposed on a steam valve connection port 101, and fixedly connected to the outer diameter of the steam valve connection port 101 through the fixing assembly 102;

[0033] The hydraulic motor unit 200 includes a stopper assembly 202 disposed on the hydraulic motor body 201 and fixed to the outer diameter of the hydraulic motor body 201 through the stopper assembly 202;

[0034] The anti-recoil limit unit 300 is arranged between the fixing component 102 and the limit component 202 to avoid a sudden relative displacement between the fixing component 102 and the limit component 202. The fixing component 102 and the limit component 202 are connected to prevent a sudden relative displacement between the fixing component 102 and the limit component 202.

[0035] Among them, the anti-recoil limit unit 300 is configured as a hanging limit component 301 hung on the valve connecting port 101 and the oil motor body 201. Through the connection of the anti-recoil limit unit 300 set on the valve connecting port 101 and the hanging limit component 301 on the oil motor body 201, recoil is prevented when the oil motor body 201 is disassembled or installed.

[0036] Furthermore, the oil motor unit 200 includes a fixed sleeve 202a arranged on the oil motor body 201, a fixed snap ring 202b arranged on one side of the fixed sleeve 202a, a block 202c arranged on the fixed snap ring 202b, and a triangular connecting rod 202d arranged on the block 202c. The fixed sleeve 202a and the fixed snap ring 202b cooperate to fix the outer diameter of the oil motor body 201.

[0037] Furthermore, a buckle 202e is provided on the fixed snap ring 202b, and a rotating shaft 202f is rotatably provided at the rear end of the fixed snap ring 202b. The snap ring 202b stuck on the outer diameter of the oil motor body 201 can be fixed by the fixed snap ring 202b and the buckle 202e.

[0038] Furthermore, the fixing assembly 102 includes a fixing sleeve 102a arranged on the outer diameter of the valve connecting port 101, a fixing clamping ring 102b arranged on the fixing sleeve 102a, a clamping block 102c arranged on the fixing clamping ring 102b, and a triangular connecting rod 102d arranged on the clamping block 102c. The outer diameter of the valve connecting port 101 can be fixed by a clamping ring through the fixing sleeve 102a and the fixing clamping ring 102b.

[0039] Furthermore, a buckle 102e is provided on the fixed clamp ring 102b, and a rotating shaft 102f is rotatably provided at the rear end of the fixed clamp ring 202b. The fixed clamp ring 102b can be installed on the outer diameter of the valve connecting port 101 through the rotating shaft 102f, and then fixed by the buckle 102e.

[0040] During use, when the oil motor body 201 is installed on the valve connecting port 101, the fixing sleeve 102a is rotated to make the fixing ring 102b stuck on the outer diameter of the valve connecting port 101, and the rotating shaft 102f is used for rotation assistance. After the fixing ring 102b is stuck on the valve connecting port 101, the buckle 102e at the front end of the fixing ring 102b is pulled to firmly fix the fixing ring 102b on the outer diameter of the valve connecting port 101, and the fixing sleeve 202a is opened at the same time, so that the fixing ring 202b is also stuck on the outer diameter of the oil motor body 201 at the same time, and the fixing ring 202b is firmly fixed on the outer diameter of the oil motor body 201 by the buckle 202e on the fixing ring 202b, so that both the valve connecting port 101 and the oil motor body 201 can be fixed and limited.

[0041] The hanging limit assembly 301 can be hung on the top of the valve connection port 101 and the oil motor body 201 through the top connecting plate 301e of the triangular connecting rod 1 102d and the triangular connecting rod 2 202d. When the oil motor body 201 is disassembled, the oil motor body 201 is limited. After the operator removes the bolts, the hanging limit assembly 301 limits the limit assembly 202 and the fixing assembly 102, so that the fixing assembly 102 and the limit assembly 202 limit the valve connection port 101 and the oil motor body 201, so as to prevent the valve connection port 101 from being blocked when the bolts are removed. The spring sheet inside the body is squeezed, causing the valve connection port 101 to recoil and cause damage. After the operator removes the bolts between the valve connection port 101 and the oil motor body 201, the valve connection port 101 is fixed to the oil motor body 201 through the limit of the hanging limit assembly 301. The motor 301a on the hanging limit assembly 301 slowly rotates, so that the limit assembly 202 moves slowly with the oil motor body 201, so that the oil motor body 201 is removed from the valve connection port 101, and at the same time, the spring sheet inside the oil motor body 201 is unloaded to prevent the oil motor from The main body 201 may recoil, and if there is lubricating oil or the like on the outer diameter of the oil motor main body 201 and the valve connection port 101, a structure that is inconvenient to fix may exist, and a vertical limiting assembly 302 may be used. By moving the vertical limiting assembly 302 to the bottom of the valve connection port 101 and the oil motor main body 201, the valve connection port 101 may be fixed by the fixing assembly 102, and the limiting assembly 202 may fix the oil motor main body 201. By fixing and limiting the vertical limiting assembly 302, the oil motor main body 201 may also be fixed and limited, so as to prevent the oil motor main body 201 from recoil during the disassembly process. When the oil motor body 201 is installed, it is necessary to squeeze the internal spring of the oil motor body 201. The oil motor body 201 can be moved by means of the hanging limit assembly 301 and the vertical limit assembly 302, and the spring sheet inside the oil motor body 201 can be squeezed while moving, to prevent the operator from squeezing the oil motor body 201 during installation, resulting in uneven squeezing surface and preventing the oil motor body 201 from recoil, causing personal injury, and helping to squeeze the internal spring sheet during the installation stage to avoid recoil and ensure uniform preload torque, thereby preventing installation quality problems.

[0042] Example 2, reference Figure 1 - Figure 4, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: a hanging limit assembly 301 includes a connecting plate 301e arranged on the top of the fixing assembly 102 and the limit assembly 202, a tooth plate 301d arranged on the connecting plate 301e, a gear 301c arranged on the tooth plate 301d, and a motor 301a arranged on the gear 301c. Through the cooperation between the hanging limit assembly 301 and the fixing assembly 102 and the limit assembly 202, the valve connecting port 101 and the oil motor body 201 can be fixed and limited.

[0043] Compared with Example 1, further, the anti-recoil limit unit 300 is configured as a vertical limit component 302 arranged on the ground where the valve connection port 101 and the oil motor body 201 are set, and is connected to the limit component 202 and the fixing component 102 through the vertical limit component 302 for limiting and fixing.

[0044] During use, when the oil motor body 201 and the valve connection port 101 are installed, if there is no space at the bottom of the oil motor body 201 and the valve connection port 101, and it is inconvenient to use the structure of the vertical limit assembly 302, the hanging limit assembly 301 is moved to the bottom of the valve connection port 101 and the oil motor body 201 for fixing, and then the fixing clamp ring 102b is opened and clamped on the valve connection port 101 with the assistance of the rotating shaft 102f for fixing, and the buckle 202e on the fixing clamp ring 202b is opened so that the fixing clamp ring 202b can be clamped on the oil motor body 201 for fixing, and the triangular connecting rod 102d is rotatably connected to 301g, and the triangular connecting rod 202d is rotatably connected to the rotating connecting rod 2 302h. After the fixing is completed, when the oil motor body 201 is disassembled, the valve connection port 101 is fixed by the fixing assembly 102 and the limit assembly 202. After being fixed to the oil motor body 201, the operator removes the bolts between the oil motor body 201 and the valve connection port 101, and starts working through the motor 1 301a on the hanging limit assembly 301 so that the limit assembly 202 fixes and limits the oil motor body 201 to continue to be connected to the valve connection port 101, and rotates the motor 1 301a to make the gear 301c start to rotate, so that the tooth plates 301d on both sides start to move left and right, and the movement of the tooth plates 301d causes the connecting plate 301e to also move, so that the triangular connecting rod 1 102d and the triangular connecting rod 2 202d start to move left and right, and the limit assembly 202 moves to one side, and the movement of the limit assembly 202 causes the oil motor body 201 to also start to move, and then slowly disassemble the oil motor body 201 to prevent the oil motor body 201 from recoil during disassembly, until the oil motor body 201 is separated from the valve connection port 101 and the disassembly is completed.

[0045] When installing the oil motor body 201, the fixing assembly 102 is fixedly connected to the steam valve connection port 101 by the same connection method as above, and the limiting assembly 202 is fixedly connected to the oil motor body 201. Through the reverse rotation of the motor 1 301a, the gear 301c and the tooth plates 301d on both sides begin to move in the opposite direction, so that the tooth plates 301d move toward the steam valve connection port 101 with the triangular connecting rod 1 102d and the triangular connecting rod 2 202d. When the oil motor body 201 fits the steam valve connection port 101, the spring sheet inside the oil motor body 201 begins to be squeezed through the movement of the limiting assembly 202 and the vertical limiting assembly 302, so that the extruded oil motor body 201 can be tightly fitted on the steam valve connection port 101, to prevent the operator from preventing the oil motor body 201 from recoil due to uneven extrusion surface when the oil motor body 201 is installed and squeezed, causing personal injury.

[0046] The remaining structures are the same as those of Example 1.

[0047] Example 3, reference Figure 5 - Figure 8 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: a vertical limiting assembly 302 includes a rotating connecting rod 302g rotatably set on the fixed assembly 102, a nut pair 302e rotatably set on the rotating connecting rod 302g, a screw rod 302f rotatably set inside the nut pair 302e, and a limiting plate 302m set on the top of the screw rod 302f. The limiting assembly 202 and the fixed assembly 102 are movably connected through the vertical limiting assembly 302.

[0048] Compared with Example 2, further, a bevel gear 2 302d is provided at the bottom of the screw rod 302f, a bevel gear 1 302c is provided on one side of the bevel gear 2 302d, and a motor 2 302b is provided on one side of the bevel gear 1 302c, and the motor 2 302b is used to make the bevel gear 1 302c and the bevel gear 2 302d rotate with the screw rod 302f.

[0049] During use, when installing the oil motor body 201 and the valve connection port 101, if there is lubricating oil or the like on the outer diameter of the oil motor body 201 and the valve connection port 101, which is not convenient for the structure of the hanging type limit assembly 301, the base 302a is moved to the bottom of the valve connection port 101 and the oil motor body 201 for fixing, and then the fixing clamp ring 102b is opened and clamped on the valve connection port 101 with the assistance of the rotating shaft 102f for fixing, and the fixing clamp ring 202a is opened and clamped on the valve connection port 101 for fixing. The buckle 202e on the b allows the fixing ring 202b to be clamped on the oil motor body 201 for fixing, and is rotatably connected to 301g through the triangular connecting rod 102d, and is rotatably connected to the rotating connecting rod 2 302h through the triangular connecting rod 202d. After the fixing is completed, when the oil motor body 201 is disassembled, the valve connection port 101 and the oil motor body 201 are fixed by the fixing assembly 102 and the limiting assembly 202, and the operator disassembles the oil motor body 201 and the valve The bolts between the connection port 101 start working through the second motor 302b at the bottom of the vertical limit assembly 302, so that the limit assembly 202 fixes and limits the oil motor body 201 to continue to be connected to the valve connection port 101, and the second motor 302b starts to rotate, so that the bevel gear 1 302c and the bevel gear 2 302d start to rotate, and the rotation of the bevel gear 2 302d causes the screw rod 302f to also start to rotate, so that the nut pair 302e on the outer diameter of the screw rod 302f starts to move up and down, and the nut pair 302e on the outer diameter of the screw rod 302f starts to move up and down. 2e starts to move upward along the screw rod 302f, so that the rotating connecting rod 1 302g and the rotating connecting rod 2 302h connected to the nut pair 302e start to move upward for support, and the limit assembly 202 moves to one side. The movement of the limit assembly 202 causes the oil motor body 201 to move as well, and the oil motor body 201 begins to be slowly disassembled to prevent the oil motor body 201 from recoil during disassembly, until the oil motor body 201 is detached from the valve connection port 101 and the disassembly is completed.

[0050] When installing the oil motor body 201, the fixing assembly 102 is fixedly connected to the valve connection port 101 by the same connection method as above, and the limit assembly 202 is fixedly connected to the oil motor body 201. By reversing the motor 2 302b, the nut pair 302e starts to move downward along the screw rod 302f, so that the screw rod 302f moves the limit assembly 202 and the oil motor body 201 toward the valve connection port 101. When the oil motor body 201 is attached to the valve connection port 101, By moving the limit assembly 202 and the vertical limit assembly 302, the spring sheet inside the oil motor body 201 begins to be squeezed, so that the extruded oil motor body 201 can fit tightly on the valve connection port 101, preventing the operator from installing the oil motor body 201 and causing the oil motor body 201 to recoil due to uneven extrusion surface, causing personal injury, and helping to squeeze the internal spring sheet during the installation stage, avoiding recoil and ensuring uniform preload torque, thereby preventing installation quality problems.

[0051] The remaining structure is the same as that of Example 2.
