Description

Technical field

[0001] The present invention relates to the technical field of track fixing, in particular to a track fixing device. Background technique

[0002] When mining coal mines, coal mining companies need to use small coal trucks for transportation. The coal trucks run on special tracks. The tracks of the coal trucks are fixed on the cement floor by fixings. The tracks of the coal trucks will be used for a period of time. When the track is fixed, the prior art uses a flat track pressure plate to fix the track on the ground through the cooperation of bolts and nuts fixed on the concrete floor. The flat structure track pressure plate cannot prevent the track from moving from side to side. When the guide rails move horizontally to the left and right, the distance between the two guide rails will continue to increase, which will seriously affect the transportation of coal trucks and pose safety hazards. Summary of the invention

[0003] In view of the defects of the prior ar...

Examples

Embodiment 1

[0029] Example 1 Figure 1-5 As shown, the embodiment of the present invention includes an I-shaped rail. Two rail fixing devices are symmetrically provided on both sides of the rail bottom plate 1 of the I-shaped rail. The rail fixing devices include a base 2, a buffer 3, a pressure plate 4, and a rail. The gusset 5, the elastic washer 6, the washer 7, the nut 8 and the bolt 9, the base 2 and the track bottom plate 1 are on the same level, the side of the base 2 close to the track bottom plate 1 is in close contact with the track bottom plate 1, and the top of the base 2 Holding the side surface of the track bottom plate 1 helps prevent track misalignment. The side of the base 2 away from the track bottom plate 1 is provided with a base side wall. The angle between the base side wall and the bottom surface of the base 2 is a right angle or an obtuse angle. When it is a right angle, a greater blocking force can be obtained. When an obtuse angle is selected, it can obtain a block...

Embodiment 2

[0044] Example 2 such as figure 2 , image 3 , Figure 4 , Image 6 with Figure 7 As shown, another embodiment of the present invention includes an I-shaped track. Two rail fixing devices are symmetrically provided on both sides of the track bottom plate 1 of the I-shaped track. The rail fixing devices include a base 2, a cushion 3.1, and a spring 3.2. , Pressure plate 4, rail buckle plate 5, elastic washer 6, washer 7, nut 8 and bolt 9, the base 2 and the track bottom plate 1 are on the same level, the side of the base 2 close to the track bottom plate 1 and the track bottom plate 1 There is a certain distance between the base 2 and the side of the base 2 away from the track bottom plate 1 is provided with a base side wall. The angle between the base side wall and the bottom surface of the base 2 is a right angle. Blocking strength, the side wall of the base and the base 2 are integrally formed. This embodiment is formed by casting or forging. The base 2 is provided with a th...

Embodiment 3

[0057] Example 3 such as Figure 1-8 As shown, the rail fixing device in embodiment 1 and the rail fixing device in embodiment 2 are used together, the inner side of the rail is installed with the rail fixing device in embodiment 1, and the outer side of the rail is installed with the rail fixing device in embodiment 2. The two devices are symmetrically arranged.

[0058] When in use, first install the track fixing device in embodiment 1 on the inner side of the track bottom plate 1, press the base 2 against the side of the track bottom plate 1, and the track base 2 and the rail gusset 5 together define the position of the track bottom plate 1, and then The track fixing device in the second embodiment is installed symmetrically on the outer side of the track bottom plate 1, and the spring 3.2 is in a compressed energy storage state. At this time, the track bottom plate 1 is fixed at a designated position. When the coal truck is running on the track, the track bottom plate 1 will...
