[0002] A track switch machine is a crucial signaling infrastructure device used to reliably change the position of a turnout, alter its direction of operation, lock the turnout switch rails, and indicate the turnout's position. It plays a vital role in rail transit, ensuring safe operation, improving transport efficiency, and reducing the workload of train operators.

[0003] The working principle of a track switch machine is relatively simple. When a train route needs to be changed, the control system sends a command to the motor. The motor drives a push plate through a reducer and friction coupling, which in turn pushes the switch rail on the track, thus changing the track. In this process, the switch machine has a compact structure and stable and reliable performance, ensuring smooth switching and locking of the turnout.

[0004] However, the top of the track switch machine is installed using a cover and bolts. Since the track switch machine is exposed to the outside for extended periods, the bolts tend to rust, making it difficult to open the top cover and hindering maintenance. Therefore, this paper proposes a track switch machine that facilitates maintenance. Utility Model Content

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Specific implementation examples are given below.

[0028] Please see Figure 1 - Figure 6This utility model provides a track switch machine that is easy to maintain, including a switch machine housing 100. A cover 200 is provided at the top of the switch machine housing 100 for tightly closing the housing. A fixing device 300 is provided on the right side of the cover 200 for fixing the cover 200 to the switch machine housing 100. A fixing strip 201 for inserting into the right end of the cover 200 is fixedly installed at the right end. The fixing device 300 includes two locking components 330 disposed within the fixing strip 201 for fixing the fixing strip 201 within the switch machine housing 100. An adjusting component 320 is provided to drive the two locking components 330 to move in opposite directions. A driving component 310 is provided inside the fixing bar 201 to drive the adjusting component 320 to rotate. Therefore, when it is necessary to inspect the structure inside the switch machine housing 100, the adjusting component 320 can be rotated by the driving component 310, which will drive the two locking components 330 to move closer to each other, thereby releasing the fixing bar 201 from the switch machine housing 100. This allows the cover 200 to be quickly removed from the top of the switch machine housing 100, making it convenient for operators to quickly inspect the structure inside the switch machine housing 100.

[0029] Furthermore, such as Figure 2 and Figure 3 As shown, the right end of the switch machine housing 100 is provided with a long groove 103 for placing the fixing strip 201. The front and rear ends of the long groove 103 are provided with locking grooves 104 for cooperating with the locking assembly 330 to fix the fixing strip 201 in the long groove 103. Therefore, the fixing strip 201 can be inserted into the long groove 103, and the fixing strip 201 can be locked in the long groove 103 by the cooperation of the fixing device 300 and the locking groove 104. Thus, the switch machine housing 100 can be sealed and tightened by the cover 200.

[0030] The top of the switch machine housing 100 has two sliding grooves 102 for the cover 200 to slide left and right. The two sliding grooves 102 are symmetrically distributed at the top of the switch machine housing 100. The cross-section of the sliding grooves 102 is cross-shaped to prevent the cover 200 from being pulled up and thus causing the switch machine housing 100 to open. The bottom of the switch machine housing 100 is fixedly installed with four fixing plates 101 for fixing the switch machine housing 100. The four fixing plates 101 are welded to the bottom of the switch machine housing 100 in a rectangular array. The center of the fixing plate 101 has a round hole to facilitate the use of bolts to pass through the round hole of the fixing plate 101 and connect with the thread between the bolt and the nut, so that the switch machine housing 100 can be installed on the mounting platform of the track.

[0031] Furthermore, such as Figure 4 and Figure 5As shown, a slider 204 for sliding in the slide groove 102 is fixedly installed at the bottom of the cover 200. There are two sliders 204, and the two sliders 204 are symmetrically welded to the bottom of the cover 200. The cross-section of the slider 204 is cross-shaped, and the shape and size of the slider 204 are the same as the shape and size of the slide groove 102. Therefore, when it is necessary to seal the switch machine box 100 through the cover 200, the two sliders 204 at the bottom of the cover 200 can be moved to the left in the two slide grooves 102 to seal the switch machine box 100. A protrusion 205 is fixedly installed at the top of the cover 200.

[0032] The right end of the fixing strip 201 is provided with a groove 202 for driving the drive assembly 310 to rotate. The fixing strip 201 is L-shaped to facilitate the insertion of the fixing strip 201 into the long groove 103. A sealing plate 203 for sealing the groove 202 is movably connected in the groove cavity. Therefore, the groove 202 can be sealed by the sealing plate 203, which can prevent the drive assembly 310 in the groove 202 from rusting due to long-term use, thus preventing the box cover 200 from being quickly removed from the switch machine box 100.

[0033] Furthermore, such as Figure 4 , Figure 5 and Figure 6 As shown, the fixing device 300 includes two locking components 330 disposed within the fixing bar 201 for fixing the fixing bar 201 within the switch machine housing 100, an adjusting component 320 disposed within the fixing bar 201 for driving the two locking components 330 to move in opposite directions, and a driving component 310 disposed within the fixing bar 201 for driving the adjusting component 320 to rotate.

[0034] The drive assembly 310 includes a rotating shaft 312 disposed within the fixed bar 201 for rotation, and the shaft body of the rotating shaft 312 is connected to the fixed bar 201 via a bearing to facilitate the rotation of the rotating shaft 312; a handwheel 311 for driving the rotating shaft 312 to rotate is fixedly installed at the right end of the rotating shaft 312, and the handwheel 311 is located in the groove 202; a bevel gear 313 for driving the adjustment assembly 320 to rotate is fixedly installed at the left end of the rotating shaft 312.

[0035] The adjusting assembly 320 includes a threaded rod 321 disposed within the fixing bar 201 for driving two locking assemblies 330 to move in opposite directions. The front and rear ends of the threaded rod 321 are connected to the fixing bar 201 via bearings to facilitate rotation. The threaded rod 321 has two threaded sections symmetrically distributed on its body, with opposite thread directions. This allows the two locking assemblies 330 located at the two threaded sections of the threaded rod 321 to move in opposite directions and insert into the locking groove 104, thus fixing the fixing bar 201 within the long groove 103. A second bevel gear 32 is fixedly mounted in the middle of the threaded rod 321 for meshing with a first bevel gear 313. 2; Thus, when it is necessary to inspect the structure inside the switch machine housing 100, the handwheel 311 can be used to drive the rotating shaft 312 to rotate, and the meshing connection between the first bevel gear 313 and the second bevel gear 322 can make the threaded rod 321 rotate synchronously with the rotating shaft 312; the two locking components 330 located at the two threads of the threaded rod 321 move in opposite directions and bring the two locking components 330 closer to each other from the locking groove 104, so that the fixing strip 201 is fixed in the long groove 103. Then, the cover 200 is moved to the right, and the bottom slider 204 of the cover 200 moves to the right along the sliding groove 102, so that the cover 200 can be removed from the top of the switch machine housing 100, so as to facilitate the operator to inspect the structure inside the switch machine housing 100.

[0036] The locking assembly 330 includes a threaded sleeve 331 disposed within the fixing bar 201 for threaded connection with the threaded rod 321. A locking plate 332 for fixing the fixing bar 201 within the switch machine housing 100 is fixedly mounted at the end of the threaded sleeve 331 away from the second bevel gear 322. There are two locking plates 332, symmetrically welded vertically to the end of the threaded sleeve 331 away from the second bevel gear 322. Therefore, when maintenance is required on the structure within the switch machine housing 100, the rotating shaft 312 can be rotated via the handwheel 311. The meshing connection between bevel gear 313 and bevel gear 322 allows the threaded rod 321 to rotate synchronously with the rotating shaft 312. The two threaded sleeves 331 located at the two threads of the threaded rod 321 move closer to each other, allowing the locking plate 332 to be stored in the fixing bar 201 from the locking groove 104. Then, by moving the cover 200 to the right and causing the bottom slider 204 of the cover 200 to move to the right along the slide groove 102, the cover 200 can be removed from the top of the switch machine housing 100, making it convenient for operators to inspect the internal structure of the switch machine housing 100.

[0037] Working principle: When it is necessary to inspect the structure inside the switch machine housing 100, the sealing plate 203 can be flipped to open the groove 202, and then the handwheel 311 can be driven to rotate the shaft 312. The meshing connection between the first bevel gear 313 and the second bevel gear 322 allows the threaded rod 321 to rotate synchronously with the shaft 312. The two threaded sleeves 331 located at the two threads of the threaded rod 321 move closer to each other, and the locking plate 332 can be stored in the fixing strip 201 from the locking groove 104. Then, the cover 200 is moved to the right, and the slider 204 at the bottom of the cover 200 moves to the right along the groove 102, so that the cover 200 can be removed from the top of the switch machine housing 100 to facilitate the operator to inspect the structure inside the switch machine housing 100.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
