Description

Technical Field

[0001] The utility model relates to the technical field of rail transportation, in particular to a pin sleeve type rail fixing device. Background Art

[0002] Tracks are mainly used for the movement of transport vehicles. Tracks and sleepers are usually fixed by means of spikes and bolts. This fixing method has poor stability and is easy to loosen. In order to improve stability, existing tracks are usually limited by deformed pins.

[0003] For example, patent application number CN201120142540.5 discloses a pin-sleeve type rail fixing device, in which four round hole sleeves 1 respectively located on both sides of the same rail fixing device base 5 keep the track gauge unchanged, and the pins 3 passing through the round hole sleeves 1 are deformed along the inclined surface of the track 2, so that the rail fixing device is tightly fixed to the track;

[0004] However, the service life of this fixing method is relatively limited. The main reason is that the vibration of the track will be transmitted to the pin and the round hole sleeve, causing the pin to deform and causing the track to loosen. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a pin sleeve type rail fixing device to solve the problem of short service life of the rail positioning method in the prior art described in the background technology.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a pin sleeve type rail fixing device, comprising

[0007] Rail fixer;

[0008] Two tracks, located at both ends of the track holder;

[0009] A plurality of rail fixing components are respectively arranged on the rail fixing device and located at both ends of the rail, and are used to press the rail;

[0010] The rail fixing assembly includes

[0011] An iron plate, embedded in the upper surface of the rail holder;

[0012] A positioning plate, fixedly connected to the iron plate, and having a socket;

[0013] A latch passes through the insertion hole and is provided with a limit plate;

[0014] The connecting plate has a first baffle at one end and a second baffle at the other end. The second baffle abuts against the bent portion of the latch. The second baffle has an inserting plate. The positioning plate has a limiting groove at a position corresponding to the inserting plate, and the inserting plate extends into the limiting groove.

[0015] Preferably: the iron plate has an embedded part, the embedded part is embedded in the rail fixing device, and the embedded part is T-shaped.

[0016] Preferably: the upper surface of the positioning plate is an inclined surface.

[0017] The beneficial effects of adopting the above technical solution are:

[0018] During use of the present application, the first baffle on the connecting plate can block the limiting plate, the second baffle can block the bent part of the latch, and the plug on the second baffle can extend into the limiting groove of the positioning plate, so that the connecting plate will not separate from the positioning plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-4 In the first embodiment, a pin-sleeve type rail fixing device includes

[0026] Rail fixer 10;

[0027] Two rails 20 are respectively located at two ends of the rail fixing device 10;

[0028] A plurality of rail fixing components are respectively arranged on the rail fixing device 10 and located at both ends of the rail 20, and are used to clamp the rail 20;

[0029] The rail fixing assembly includes

[0030] An iron plate 30 is embedded in the upper surface of the rail fixing device 10;

[0031] A positioning plate 40 is fixedly connected to the iron plate 30 and has a plug hole 41;

[0032] A latch 50 passes through the insertion hole 41, and a limiting plate 51 is provided on the latch 50;

[0033] The connecting plate 60 has a first baffle 61 at one end and a second baffle 62 at the other end. The second baffle 62 abuts against the bent portion of the latch 50 . The second baffle 62 has an insert plate 63 . The positioning plate 40 has a limiting groove 42 at a position corresponding to the insert plate 63 . The insert plate 63 extends into the limiting groove 42 .

[0034] This embodiment is implemented as follows:

[0035] When the present application is in use, the first baffle plate 61 is placed close to the limit plate 51, and the connecting plate 60 is placed close to the upper surface of the positioning plate 40, and then the second baffle plate 62 is hammered to bend the second baffle plate 62 relative to the connecting plate 60, so that the second baffle plate 62 can rest against the bent part of the latch 50, and the plug plate 63 on the second baffle plate 62 can enter the limit groove 42, and the plug plate 63, the first baffle plate 61, and the second baffle plate 62 can fix the position of the connecting plate 60.

[0036] Compared with the prior art, the present application has the advantage of being able to improve the stability of the latch.

[0037] See also Figure 1 , 2 , 3, 4, the iron plate 30 has an embedded part 31, the embedded part 31 is embedded in the rail fixing device 10, and the embedded part 31 is T-shaped;

[0038] The embedded part 31 of the present application is embedded in concrete when the track fixing device 10 is manufactured, so as to stabilize the iron plate 30 .

[0039] See also Figure 1 , 2 , 3, 4, the upper surface of the positioning plate 40 is an inclined surface;

[0040] Setting the upper surface of the positioning plate 40 as an inclined surface can make the side of the positioning plate 40 having the limiting groove 42 thicker, thereby improving the quality of the positioning plate 40 .

[0041] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
