Embodiment 1

[0052] A rail row joint for medium and low-speed maglev trains, which consists of front F-shaped steel 1, rear F-shaped steel 2, middle F-shaped steel 3, single-key slider 4, slider bolt 5, and supporting slide plate 6. The front F-shaped steel 1 and the rear One end of the F-shaped steel 2 is processed into a mirror-symmetric groove structure, and the two ends of the middle F-shaped steel 3 are processed into a mirror-symmetrical convex plate structure. The processing ends of the front F-shaped steel 1, the middle F-shaped steel 3, and the rear F-shaped steel 2 are similar Correspondingly arranged in order from front to back, two pairs of corresponding wing plates are connected together by two connecting single-key sliders 4 and connecting slider bolts 5, and two pairs of corresponding wing plates are connected by two supporting sliders 6 and countersunk head bolts 7. The corresponding groove structure is connected with the convex structure to form an F-rail joint as a whole. ...

Embodiment 2

[0077] The front chute support plate 1A and the rear chute support plate 2A are as Figure 4 As shown, it is a pair of rectangular grooves with exactly the same size, which are located on the webs of the two opposite ends of the front F-shaped steel 1 and the rear F-shaped steel 2, and the distance from the ends of the front F-shaped steel 1 and the rear F-shaped steel 2 is equal to the front The width of baffle plate 1F and rear baffle plate 2F; Its depth is equal to the thickness of support slide plate 6; Its width is the width of support slide plate 6 plus 2 times of front and rear expansion and contraction; Its length is about the width in F-shaped steel web groove (see Figure 5 ), its main function is to make the supporting slide plate 6 slide back and forth in the groove after being connected with the web sliding plate 3A with the countersunk bolt 7 in the front chute support plate 1A and the rear chute support plate 2A, The sliding amount is equal to the designed expan...

Embodiment 3

[0093] The front chute support plate 1A and the rear chute support plate 2A are as Figure 4 As shown, it is a pair of rectangular grooves with exactly the same size, which are located on the webs of the two opposite ends of the front F-shaped steel 1 and the rear F-shaped steel 2, and the distance from the ends of the front F-shaped steel 1 and the rear F-shaped steel 2 is equal to the front The width of baffle plate 1F and rear baffle plate 2F; Its depth is equal to the thickness of support slide plate 6; Its width is the width of support slide plate 6 plus 2 times of front and rear expansion and contraction; Its length is about the width in F-shaped steel web groove (see Figure 5 ), its main function is to make the supporting slide plate 6 slide back and forth in the groove after being connected with the web sliding plate 3A with the countersunk bolt 7 in the front chute support plate 1A and the rear chute support plate 2A, The sliding amount is equal to the designed expan...

Abstract

The invention relates to a joint for a track panel, in particular to an F-shaped steel track joint with more expansion amount for a middle and low speed maglev track. A pair of long front and back F-shaped steels and a short middle F-shaped steel are machined into joint structures which are mutually matched; the expansion amount of the joint structures can reach 20-60mm; and the expansion amount of the two connected joints can reach 40-120mm. The joint has the advantages of high installation and alignment accuracy, the expansion amount of thermal expansion and thermal contraction and the like and effectively solves the problem that a track needs more expansion amount.

Description

technical field [0001] The invention relates to a joint for a rail row, in particular to a joint with a large amount of expansion and contraction for a track of a medium-low speed maglev train. Background technique [0002] The medium- and low-speed maglev train rail transit system with a speed of 80-150 kilometers per hour is being rapidly developed and popularized due to its excellent comprehensive performance. Then it is installed and fixed on the foundation by high-strength bolts, and multiple rail rows are longitudinally connected together through joints to form a track. Each rail row and rail row must not only be installed and aligned in the three-dimensional directions of the longitudinal (X), lateral (Y) and vertical (Z) joints, but also take into account the expansion and contraction caused by the longitudinal (X) expansion and contraction. question. People have done a lot of research for this, and Japanese patents JP4-153401, JP2003-184006, US patent US5199674, a...
