Description

Technical Field

[0001] The utility model relates to the technical field of coupling production, and more specifically, to a production device for a substation connecting shaft. Background Art

[0002] In the power system, especially in large generator sets (such as steam turbine generator sets), there are indeed mechanical connecting shafts (usually called couplings). A coupling is a device used to connect two rotating components (such as a steam turbine rotor and a generator rotor), and its function is to transmit the rotational motion of one component to the other component. In a power plant, couplings are usually used to connect steam turbines and generators to ensure that the two can rotate synchronously and transmit power.

[0003] Currently, when producing a substation connecting shaft, in order to ensure its use, most of them need to use an electroplating process to electroplate the connecting shaft to improve corrosion resistance, increase hardness, prevent wear, improve conductivity and smoothness. When electroplating the connecting shaft, a fixture is needed to put the connecting shaft to be electroplated into the electroplating bath, and then after electroplating is completed, the connecting shaft is taken out of the electroplating bath through the fixture. However, when the fixture clamps the connecting shaft, it will contact a part of the surface of the connecting shaft. When electroplating this part of the mutually contacting part, it will cause the electroplating layer to be relatively weak or unable to complete the plating, affecting the electroplating quality of the connecting shaft.

[0004] Therefore, in order to solve the above technical problems, this application proposes a production device for a substation connecting shaft. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a production device for a substation connecting shaft.

[0007] Adjusting parts, which are provided in multiple groups and are respectively installed on each of the mounting plates. A clamping part is installed on each of the adjusting parts. By closing the clamping parts, the clamping action of the connecting shaft is realized. When the clamping parts clamp the connecting shaft, a plurality of adjusting parts are used to make the plurality of clamping parts clamp the connecting shaft alternately.

[0008] Preferably, the adjustment portion includes a mounting ring and a turntable rotatably arranged on the mounting plate, and the turntable is inserted in the central gap of the mounting ring, and a latch is provided on the inner wall surface of the mounting ring. Two mutually symmetrical limit rotating plates are rotatably arranged on the turntable through a torsion spring, and a knob with a protrusion on the outer peripheral surface is rotatably arranged on the turntable. When the knob rotates, the protrusion respectively abuts against the surfaces of the limit rotating plates on both sides, and the clamping portion is arranged on the mounting ring.

[0009] Preferably, the clamping portion includes a forward and reverse screw rod fixedly arranged on the surface of the mounting ring and a clamping plate threadedly arranged on the forward and reverse screw rod.

[0010] Preferably, a plurality of spring columns are arranged at equal intervals on the clamping plate, and a clamping plate is fixedly provided on each of the spring columns, and an arc-shaped abutment head is provided at the end of the clamping plate.

[0011] Preferably, the substation connecting shaft production equipment further comprises a driving unit, which is disposed on one of the mounting plates and is simultaneously transmission-connected to a plurality of turntables, and is used to rotate the plurality of turntables simultaneously.

[0022] like Figures 1-4 As shown, the utility model provides a transformer substation connecting shaft production device, including a frame 1 and a plurality of mounting plates 2 arranged on the frame 1, the frame 1 is connected to an external lifting device, and the frame 1 and the mounting plates 2 can be raised or lowered by the lifting device, and the lifting device can be a hydraulic lifting device or an electric lifting device, which is a prior art and will not be described in detail here;

[0023] The substation connecting shaft production equipment also includes an adjusting part, which is provided with multiple groups and respectively installed on each of the mounting plates 2, and each of the adjusting parts is installed with a clamping part, and the clamping action of the connecting shaft is realized by closing the clamping part. When the frame 1 and the mounting plate 2 and the connecting shaft clamped by the clamping part thereon are placed into the electroplating bath for electroplating through an external lifting device, the multiple clamping parts are alternately clamped on the connecting shaft through the adjusting part to prevent the occurrence of electroplating dead angles;

[0024] In one embodiment of the utility model, the adjustment part includes a mounting ring 8 and a turntable 15 rotatably arranged on the mounting plate 2, and the turntable 15 is inserted in the central gap of the mounting ring 8, and a latch 14 is provided on the inner wall surface of the mounting ring 8. Two mutually symmetrical limit rotating plates 13 are rotatably arranged on the turntable 15 through a torsion spring, and a knob 9 with a protrusion 16 on the outer peripheral side surface is rotatably arranged on the turntable 15. When the knob 9 is rotated, the protrusion 16 respectively abuts against the surface of the limit rotating plates 13 on both sides, so that The clamping portion is arranged on the mounting ring 8. When the connecting shaft to be electroplated needs to be clamped, the connecting shaft is first placed in the waiting clamping position of the clamping portion, and then the multiple turntables 15 are rotated simultaneously by the driving action of the driving portion arranged on one of the mounting plates 2 and connected to the multiple turntables 15 at the same time. Here, the knobs 9 on the multiple turntables 15 need to be rotated to different contact positions so that the protrusions 16 thereon contact the surfaces of the limit rotating plates 13 at different positions. For example, the protrusion 16 on one of the turntables 15 contacts the surface of the limit rotating plates 13 at different positions.Figure 3 On the limiting rotating plate 13 on the left side, the limiting rotating plate 13 being resisted at this time is stuck between the teeth 14 on the mounting ring 8. The knobs 9 on another or multiple turntables 15 are alternately rotated in sequence to the left side or the right side as shown in Figure 3 the figure. In this way, the limiting rotating plates 13 on each turntable 15 will abut against the teeth 14 of the corresponding mounting ring 8 in different directions. Among them, when the limiting rotating plate 13 on the left side in Figure 3 the figure rotates with the turntable 15, since the limiting rotating plate 13 is resisted by the convex block 16, only the mounting ring 8 can be rotated counterclockwise. When the turntable 15 rotates clockwise, the limiting rotating plate 13 deflects through the torsion spring and cannot drive the mounting ring 8 to rotate. Similarly, when other turntables 15 rotate through the driving part, the mounting ring 8 can only be rotated in one of the directions;

[0025] It can be understood that after the connecting shaft is placed at the position to be clamped, the driving part is used to rotate multiple turntables 15 simultaneously. In this way, some of the mounting rings 8 will rotate, while some of the mounting rings 8 will not rotate. The rotating mounting rings 8 will drive the clamping part to clamp the connecting shaft, and the clamping parts on the non-rotating mounting rings 8 will not move. After clamping, the connecting shaft is placed in the electroplating bath. After a period of time, the knobs 9 on each rotating turntable 15 are rotated in the opposite direction, and then the driving part is used to reverse each turntable 15. In this way, the mounting rings 8 that failed to rotate before rotate, and the mounting rings 8 that rotated before cannot rotate. At this time, the clamping part is replaced to clamp the connecting shaft, and there will be no electroplating dead angle, improving the electroplating effect on the connecting shaft;

[0026] In another embodiment of the present utility model, the driving part includes a driving motor 3 installed on one of the mounting plates 2. The turntables 15 on two adjacent mounting plates 2 are all installed with a second belt 7 through a synchronous pulley. One of the turntables 15 on the transmission shaft of the driving motor 3 is installed with a first belt 4 through a pulley. By starting the driving motor 3, one of the turntables 15 is rotated through the first belt 4, and then multiple turntables 15 are rotated simultaneously through multiple second belts 7;

[0027] In another embodiment of the present utility model, the above-mentioned clamping part includes a positive and negative screw rod 5 fixedly arranged on the surface of the mounting ring 8 and a clamping plate 6 threadedly arranged on the positive and negative screw rod 5. When the positive and negative screw rod 5 rotates, the clamping plates 6 approach each other to clamp the connecting shaft. When the positive and negative screw rod 5 rotates, the clamping plates 6 approach or move away from each other through the thread structure of the positive and negative screw rod 5, so as to clamp the connecting shaft;

[0028] In order to improve the clamping effect on the connecting shaft, a plurality of spring columns 10 are arranged in equal intervals and in an array on the clamping plate 6, and a clamping plate 11 is fixedly arranged on each of the spring columns 10. An arc-shaped abutting head 12 is arranged at the end of the clamping plate 11. In this way, when the deformation amounts of the plurality of spring columns 10 are different, the respective clamping plates 11 are in different positions, and connecting shafts of different shapes can be clamped. Moreover, the arc-shaped abutting head 12 at the end is made of an elastic material, which increases the friction with the connecting shaft and prevents slipping.

[0029] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention; any ordinary technician in the industry can smoothly implement the present invention according to the illustrations in the specification and the above description; however, any equivalent changes made by those skilled in the art within the scope of the technical solution of the present invention by making some changes, modifications and evolutions using the technical content disclosed above are equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention still fall within the protection scope of the technical solution of the present invention.
