Description

Technical Field

[0001] The utility model relates to the technical field of track connection, and more specifically to a track telescopic connection device used for an openable railway bridge. Background Art

[0002] In the existing technology, open and closed railway bridges need to be built in rivers and other water areas due to the needs of navigation, landscape, etc.

[0003] Since the bridge itself needs to be opened and closed, the railway track needs to be opened and closed and connected according to the opening and closing of the bridge during this process.

[0004] The commonly used connection structure in the prior art is: through the transmission of the gear rack, the rack is fixed under the track, and the telescopic connection of the track is realized through the gear transmission;

[0005] The track telescopic mechanism is driven by a motor reducer, which is transferred to the sprocket through a multi-link, and then the chain of the sprocket drives the transmission of the gear rack.

[0006] However, if the train brakes, starts, or other actions at the connection cause the moving track to be subjected to force away from the connection direction, the rack may fail and derailment may occur. At the same time, steel structure bridges expand and contract due to heat, and the gap between single tracks will increase after the bridge shrinks in winter, which poses a certain strength risk. The overall structure of the drive solution is complex, the movement speed is slow, and there are many maintenance points, which may lead to a high maintenance frequency. In view of the requirements of railway operation, its stability and safety need to be further improved. Utility Model Content

[0045] The utility model is described in detail below.

[0046] like Figure 1-Figure 7 As shown:

[0047] A track telescopic connection device for an openable railway bridge, used for connecting two sets of fixed rails 10 installed on a fixed side 100 and two sets of telescopic rail assemblies installed on a docking side 200, comprising a latch mechanism 2 installed on the fixed side 100 and connected to one end of the telescopic rail assembly close to the fixed rail 10, and a telescopic drive mechanism 1 installed on the docking side 200 and used for controlling the telescopic rail assembly to move closer to or away from the rail.

[0048] When the fixed rail 10 and the telescopic rail assembly need to be connected, the telescopic drive mechanism 1 controls the telescopic rail assembly to move toward the side close to the fixed rail 10, so that the telescopic rail assembly and the fixed rail 10 are docked; then the latch mechanism 2 is used to connect and fix the fixed rail 10 and the telescopic rail assembly;

[0049] In some possible implementations, in order to effectively realize the connection between the telescopic rail assembly and the fixed rail 10 and to achieve a larger telescopic range;

[0050] The telescopic rail assembly comprises a pointed rail 30 mounted on the docking side 200, and a base rail 20 slidably matched with the pointed rail 30 and connected to the telescopic drive mechanism 1;

[0051] The outer side surface of the pointed rail 30 and the inner side surface of the stock rail 20 are curved surfaces and a sliding fit is formed through the curved surfaces; the pointed corner of the pointed rail 30 is arranged on a side close to the fixed side 100 .

[0052] The combination of the point rail 30 and the base rail 20 is the same as the temperature regulator used for rails in the prior art. By locking the point rail 30, the base rail 20 can be extended and retracted, which can effectively adapt to thermal expansion and contraction.

[0053] Specifically, the base rail 20 is arranged at one end of the point rail 30 close to the fixed side 100, and the two are slidably matched by the curved surface matching on one side close to each other; the base rail 20 includes a sliding section slidably matched with the point rail 30, and a connecting section connected to one end of the sliding section close to the fixed side 100 and integrally formed; the connecting section is used to achieve docking with the fixed rail 10;

[0054] In some possible implementations, in order to effectively achieve connection with the base rail 20 and enable the base rail 20 to be driven to move along its length to achieve docking with the fixed rail 10;

[0055] The telescopic drive mechanism 1 includes a connector 11 connected to the base rail 20 , and a telescopic cylinder 12 connected to a side of the connector 11 away from the fixed rail 10 and used to control the connector 11 to move linearly toward or away from the fixed rail 10 .

[0056] The connecting member 11 is used to connect the two sets of basic rails 20 close to each other. The telescopic cylinder 12 is connected to the end of the connecting member 11 away from the fixed side 100. The telescopic end of the telescopic cylinder 12 will be connected to the connecting member 11. Under the drive of the telescopic cylinder 12, the two sets of basic rails 20 connected to the connecting member 11 can simultaneously make a linear motion close to or away from the fixed rail 10.

[0057] When it is necessary to connect the basic rail 20 with the fixed rail 10, the telescopic section 22 of the telescopic oil cylinder 12 is extended, driving the connecting member 11 and the basic rail 20 to move toward the side close to the fixed rail 10. When the fixed rail 10 and the basic rail 20 are in contact with each other on one side, the latch mechanism 2 fixes the basic rail 20; thereby effectively connecting the basic rail 20 with the fixed rail 10, so that the train can pass; otherwise, the fixed rail 10 and the basic rail 20 are disconnected;

[0058] In some possible embodiments, in order to effectively achieve connection with the stock rail 20 through the connecting member 11;

[0059] The connecting member 11 includes a reinforcing rail 111 installed inside the basic rail 20 and arranged along the long direction of the fixed rail 10, and a connecting seat 112 connected to the reinforcing rail 111 and the telescopic cylinder 12 respectively;

[0060] The reinforcing rail 111 is arranged along the length direction of the fixed rail 10 so that the connection surface between the connecting seat 112 and the basic rail 20 is larger and the connection is more stable and reliable;

[0061] In some possible implementations, in order to effectively connect two sets of parallel basic rails 20 through the connecting seat 112 so that the two sets of basic rails 20 can be docked with the fixed rail 10 at the same time and avoid deformation of the connecting seat 112 due to stress;

[0062] The connecting seat 112 comprises connecting frames 1121 of the same structure and symmetrically arranged along the sliding direction of the reinforcing rail 111, and connecting plates 1122 arranged between the two groups of connecting frames 1121 and connected to the telescopic oil cylinder 12 and the two groups of connecting frames 1121 respectively; an opening groove 1123 of an isosceles trapezoidal structure is formed on one side of the connecting seat 112 away from the telescopic oil cylinder 12, and the large end has an opening;

[0063] The two groups of connecting frames 1121 are connected to the two groups of reinforcing rails 111 respectively, and the connecting plate 1122 is arranged between the two groups of connecting frames 1121 and connected to the telescopic end of the telescopic cylinder 12, so that one group of telescopic cylinders 12 can simultaneously drive the two groups of basic rails 20 to dock with the two groups of fixed rails 10;

[0064] An opening groove 1123 having an isosceles trapezoidal structure is formed on one side of the connecting seat 112 away from the telescopic oil cylinder 12, and the large end of the opening groove 1123 has an opening, forming a Figure 3 The K-shaped structure shown; through this arrangement, it is possible to effectively prevent the connection seat 112 from being deformed when the telescopic cylinder 12 is extended and retracted;

[0065] In some possible implementations, in order to effectively achieve the connection and fixation between the latch mechanism 2 and the telescopic rail assembly;

[0066] The distance between the reinforcing rail 111 and the fixed rail 10 is smaller than the distance between the basic rail 20 and the fixed rail 10; that is, the end of the reinforcing rail 111 away from the point rail 30 will extend out of the basic rail 20 to form a convex structure;

[0067] A connecting rail 3 is provided along the length direction of the fixed rail 10 at one side of the two sets of fixed rails 10 close to each other; a slot 31 for inserting the reinforcing rail 111 is formed between one end of the connecting rail 3 close to the docking side 200 and the inner side surface of the corresponding fixed rail 10;

[0068] The protruding structure of the reinforcing rail 111 is provided with an insertion hole 1111 used in cooperation with the latch mechanism 2, and the axial direction of the insertion hole 1111 is perpendicular to the length direction of the reinforcing rail 111;

[0069] When the protruding structure of the reinforcing rail 111 is inserted into the slot 31, the basic rail 20 and the fixed rail 10 are close to each other and abut against each other, and the latch mechanism 2 is inserted into the insertion hole 1111. Since the reinforcing rail 111 and the basic rail 20 are connected as a whole, the basic rail 20 is fixed by fixing the reinforcing rail 111 through the latch mechanism 2, thereby effectively achieving the docking of the basic rail 20 and the fixed rail 10.

[0070] In some possible implementations, in order to effectively guide the movement of the base rail 20 and the reinforcement rail 111, thereby ensuring that the fixed rail 10 and the base rail 20 can be accurately aligned during the connection process;

[0071] A gusset plate 4 having a bell mouth 41 is arranged on the fixed side 100 near the docking side 200; wherein the large end of the bell mouth 41 is arranged on the side near the docking side 200; and one end of the fixed rail 10 near the docking side 200 is arranged on the small end of the bell mouth 41;

[0072] During docking, the telescopic cylinder 12 controls the connecting seat 112 to move toward the fixed side 100, thereby driving the reinforcing rail 111 and the basic rail 20 to move toward the fixed side 100. By providing a buckle plate 4 with a bell mouth 41, the moving direction of the reinforcing rail 111 and the basic rail 20 is guided. After the reinforcing rail 111 and the basic rail 20 pass through the bell mouth 41 on the side close to the fixed side 100, they are docked with the corresponding connecting rail 3 and the fixed rail 10, so that the docking accuracy is high.

[0073] In some possible implementations, in order to effectively connect and fix the two sets of reinforcement rails 111 through the latch mechanism 2, the latch mechanism 2 can be implemented by an electric push rod;

[0074] The latch mechanism 2 is disposed between two groups of slots 31; it includes a driving section 21 and two groups of telescopic sections 22 respectively connected to the driving section 21 in a transmission manner;

[0075] When the base rail 20 is in abutment with the fixed rail 10 , the insertion holes 1111 and the telescopic sections 22 are coaxially arranged, and the two sets of telescopic sections 22 are respectively inserted into the corresponding insertion holes 1111 under the drive of the driving section 21 .

[0076] The connection and fixation of the fixed rail 10 and the pointed rail 30 in the present invention, and the matching of the pointed rail 30 and the base rail 20 are the same as those in the prior art and will not be described in detail here.

[0077] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
