Description

Technical Field

[0001] This utility model relates to the field of generator technology, specifically to an auxiliary installation structure for a generator end cover. Background Technology

[0002] As a key protective and supporting component of the generator, the generator end cover primarily undertakes core functions such as sealing the internal space of the generator, isolating external dust and moisture from intrusion, supporting bearings, and fixing the rotor position. It is of great significance for ensuring the safe and stable operation of the generator and extending its service life. In modern industrial production, the assembly precision of the generator directly affects its power generation efficiency and stability, and the installation quality of the end cover is a crucial factor in ensuring the overall performance of the generator.

[0003] The existing generator connection flange is first welded to the generator body by welding, and then the end cover is installed on the flange by bolts to complete the connection and installation of the end cover and the generator body.

[0004] Chinese Utility Model Patent Publication No. CN 212412903 U discloses a connection structure between the generator body and the end cover. The specification describes a structure where several holes are drilled in the generator body, and a latch nut is inserted into each hole, replacing the flange ring. The end cover is then connected to the generator body using standard bolts. This structure is simple and easy to operate, eliminating the flange ring welding process, solving various problems caused by welding flange rings to the generator body, reducing labor costs, and allowing for a reduction in generator body wall thickness and weight, thus saving material costs and increasing market competitiveness. However, this connection structure requires the end cover to be installed first and then rotated for alignment. Furthermore, there is no pre-fixed support before the bolts are screwed in, making the end cover prone to misalignment during operation, increasing installation difficulty, and preventing rapid positioning and installation of the generator body and end cover. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide an auxiliary installation structure for generator end caps, which can effectively solve the problems in the prior art.

[0006] The technical solution adopted by this utility model is: an auxiliary installation structure for a generator end cover, including a body and an end cover body. A guide post is fixedly installed at the center of one end of the body near the end cover body. A connecting component is fixedly installed on the side of one end of the body near the end cover body. A fixing block one is fixedly installed on the outer surface of one end of the body near the end cover body. An installation groove is opened at one end of the end cover body near the guide post. A positioning groove, a sliding groove, and an inner groove are opened at one end of the end cover body near the connecting component. A fixing block two is fixedly installed on the outer surface of one end of the end cover body near the body.

[0007] Preferably, the cross-section of the guide post is the same as the cross-section of the mounting groove, and the guide post and the mounting groove are slidably installed.

[0008] The above technical solution uses a guide post with the same cross-section as the mounting groove, and the guide post and mounting groove are slidably installed. This provides initial positioning for the end cover body when installing the main body and the end cover body, ensuring quick alignment and installation of the end cover body and the main body, and also allows for quick calibration of the coaxiality of the end cover and the main body.

[0009] Preferably, the connecting component is provided with a fixing post, and a connecting buckle is fixedly installed at the end of the fixing post away from the machine body.

[0010] The above technical solution incorporates a connecting component, enabling rapid fixation of the body and end cap, thus improving installation efficiency while reducing installation difficulty.

[0011] Preferably, the diameter of the connecting buckle is larger than the diameter of the fixing post, and the connecting components are provided in three identical sets, which are arranged in a ring around the center line of the machine body.

[0012] Preferably, the diameter of the connecting buckle is the same as the diameter of the positioning groove and the inner groove, the diameter of the fixing post is the same as the diameter of the sliding groove, and the fixing post and the sliding groove are slidably connected.

[0013] The above technical solution, by having a connecting buckle with a diameter larger than that of the fixing post, and the same diameter as that of the positioning groove and the inner groove, allows the connecting buckle to slide along the slide groove to the inner groove and lock, forming a "stepped anti-detachment structure". This prevents the end cap from accidentally falling off during installation or transportation. Furthermore, the connection strength between the body and the end cap is further improved by three sets of ring-shaped connecting components.

[0014] Preferably, the positioning groove, sliding groove and inner groove are provided in three identical sets. The three sets of positioning groove, sliding groove and inner groove are all located on the center line of the end cover body and are distributed in a ring. The three sets of positioning groove, sliding groove and inner groove correspond one-to-one with the three sets of connecting components.

[0015] The above technical solution uses three sets of annularly distributed positioning grooves, sliding grooves and inner grooves that correspond one-to-one with the connecting components, which makes it easy for workers to quickly connect the machine body and the end cover body without the need for external tools. The installation is relatively simple and the connection strength is high.

[0016] Preferably, the first fixing block has a screw hole 1 at one end near the end cover body, and the second fixing block has a screw hole 2 at one end near the machine body. The screw hole 1 and the screw hole 2 have the same diameter and are located on the same horizontal line. The second fixing block has a locking screw on the side away from the machine body, and the first fixing block has a locking nut that is threadedly connected to the locking screw on the side away from the second fixing block.

[0017] With the above technical solution, after the body and end cover are connected, the end cover rotates by the sliding connection between the fixed post and the slide groove until screw hole one and screw hole two are on the same horizontal line. At this time, the locking screw passes through screw hole one and screw hole two and is threadedly connected to the locking nut, which further improves the connection strength between the body and the end cover.

[0018] Compared with the prior art, the present invention provides an auxiliary installation structure for a generator end cover, which has the following advantages: 1. The auxiliary installation structure for the generator end cover, with the cross-section of the guide post being the same as that of the mounting groove and the guide post slidingly mounted to the mounting groove, can provide initial positioning for the end cover body during the installation of the generator body and the end cover body, ensuring quick alignment and installation of the end cover body with the generator body. Furthermore, the diameter of the connecting buckle is larger than that of the fixing post, and the diameter of the connecting buckle is the same as that of the positioning groove and the inner groove, which facilitates the connecting buckle to slide along the slide groove to the inner groove and lock after passing through the positioning groove, forming a "stepped anti-detachment structure" to prevent the end cover from accidentally falling off during installation or transportation. 2. The auxiliary installation structure for the generator end cover allows the end cover body to rotate after the generator body and the end cover body are connected. This is achieved by using a fixed post and a sliding groove to make the end cover body rotate until screw hole one and screw hole two are on the same horizontal line. At this point, a locking screw is used to pass through screw hole one and screw hole two and connect with the locking nut threadedly. This achieves secondary fixation of the generator body and the end cover body, further improving the connection strength between the generator body and the end cover body.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: As Figures 1-7 As shown, the present invention provides an auxiliary installation structure for a generator end cover, comprising a body 1 and an end cover body 2. A guide post 3 is fixedly installed at the center of one end of the body 1 near the end cover body 2. A connecting component 4 is fixedly installed on the side of one end of the body 1 near the end cover body 2. A fixing block 1 5 is fixedly installed on the outer surface of one end of the body 1 near the end cover body 2. An installation groove 7 is provided at one end of the end cover body 2 near the guide post 3. A positioning groove 8, a sliding groove 9, and an inner groove 10 are provided at one end of the end cover body 2 near the connecting component 4. A fixing block 2 11 is fixedly installed on the outer surface of one end of the end cover body 2 near the body 1.

[0023] Specifically, the cross-section of the guide post 3 is the same as the cross-section of the mounting groove 7, and the guide post 3 and the mounting groove 7 are slidably installed. The advantage is that, because the cross-section of the guide post 3 is the same as the cross-section of the mounting groove 7, and the guide post 3 and the mounting groove 7 are slidably installed, it can provide initial positioning for the end cover body 2 when installing the body 1 and the end cover body 2, ensuring rapid alignment and installation of the end cover body 2 and the body 1, and allowing for rapid calibration of the coaxiality of the end cover and the body.

[0024] Specifically, the connecting component 4 is equipped with a fixing post 401, and a connecting buckle 402 is fixedly installed at the end of the fixing post 401 away from the body 1. The advantage is that the connecting component 4 enables quick fixing of the body 1 and the end cover body 2, improving installation efficiency while reducing installation difficulty.

[0025] Example 2: Figures 2-7 As shown, this is an improvement on the previous embodiment.

[0026] Specifically, the diameter of the connecting buckle 402 is larger than the diameter of the fixing post 401, and the connecting components 4 are provided in three identical sets, which are arranged in a ring around the center line of the body 1.

[0027] Specifically, the diameter of the connecting buckle 402 is the same as the diameter of the positioning groove 8 and the inner groove 10, and the diameter of the fixing post 401 is the same as the diameter of the sliding groove 9. The fixing post 401 and the sliding groove 9 are slidably connected. The advantage is that, since the diameter of the connecting buckle 402 is larger than the diameter of the fixing post 401, and the diameter of the connecting buckle 402 is the same as the diameter of the positioning groove 8 and the inner groove 10, it is easy for the connecting buckle 402 to slide along the sliding groove 9 to the inner groove 10 and lock after passing through the positioning groove 8, forming a "stepped anti-detachment structure". This prevents the end cover from accidentally falling off during installation or transportation. Furthermore, the connection strength between the body 1 and the end cover body 2 is further improved through the three sets of ring-shaped connecting components 4.

[0028] Specifically, the positioning groove 8, sliding groove 9, and inner groove 10 are all provided in three identical sets. These three sets of positioning grooves 8, sliding grooves 9, and inner grooves 10 are all located in a ring along the centerline of the end cover body 2, and each set corresponds one-to-one with one of the three connecting components 4. The advantage is that by having three sets of ring-shaped positioning grooves 8, sliding grooves 9, and inner grooves 10 correspond one-to-one with the connecting components 4, it is easy for operators to quickly connect the machine body 1 to the end cover body 2 without the need for external tools, making installation relatively simple and providing a high connection strength.

[0029] Specifically, a screw hole 6 is provided at the end of the fixing block 1 5 near the end cap body 2, and a screw hole 12 is provided at the end of the fixing block 2 11 near the body 1. The screw holes 6 and 12 have the same diameter and are on the same horizontal line. A locking screw 13 is provided on the side of the fixing block 2 11 away from the body 1, and a locking nut 14, which is threadedly connected to the locking screw 13, is provided on the side of the fixing block 1 5 away from the fixing block 2 11. The advantage is that after the body 1 and the end cap body 2 are connected, the end cap body 2 can be rotated by the sliding connection between the fixing post 401 and the slide groove 9 until the screw holes 6 and 12 are on the same horizontal line. At this time, the locking screw 13 passes through the screw holes 6 and 12 and is threadedly connected to the locking nut 14, which further improves the connection strength between the body 1 and the end cap body 2.

[0030] Working principle: In use, the cross-section of the guide post 3 is the same as the cross-section of the mounting groove 7, and the guide post 3 and the mounting groove 7 are slidably installed. This provides initial positioning for the end cover body 2 when installing the machine body 1 and the end cover body 2, ensuring quick alignment and installation of the end cover body 2 and the machine body 1, and also allowing for quick calibration of the coaxiality of the end cover and the machine body. Subsequently, the diameter of the connecting buckle 402 is larger than the diameter of the fixing post 401, and the diameter of the connecting buckle 402 is the same as the diameter of the positioning groove 8 and the inner groove 10, which facilitates the connecting buckle 402 passing through the positioning groove 8 and sliding along the groove 9. Slide to the inner groove 10 and lock to form a "stepped anti-detachment structure" to prevent the end cover from accidentally falling off during installation or transportation. After the body 1 and the end cover body 2 are connected, the end cover body 2 is rotated by the sliding connection between the fixing post 401 and the slide groove 9 until the screw hole 6 and the screw hole 12 are on the same horizontal line. At this time, the locking screw 13 passes through the screw hole 6 and the screw hole 12 and is threadedly connected to the locking nut 14 to achieve secondary fixation of the body 1 and the end cover body 2, further improving the connection strength between the body 1 and the end cover body 2, and the installation difficulty is low.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
