[0026] The technical solution in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings. The described embodiments are only some of the embodiments, not all of them. Based on the embodiments in this solution, all other embodiments obtained by ordinary technicians in this field without making creative work are within the protection scope of this solution.

[0027] Example 1

[0028] like Figures 1 to 4 As shown, this embodiment designs a sleeper fixing frame for ballastless track adjustment, including components such as a fixing cross bar 3, a wedge block 4 and an anti-slip pad 5.

[0029] The ballastless track comprises two mutually parallel steel rails 2, and a plurality of sleepers 1 are fixedly connected below the steel rails 2. The ballastless track comprises a rail bottom, a rail waist and a rail head, wherein the rail head is located above the rail bottom, and the rail waist is located between the rail bottom and the rail head.

[0030] The fixed cross bar 3 is a long bar structure, and specifically a square tube structure can be adopted. The fixed cross bar 3 is provided with two T-slots 32, which are respectively located at the left and right ends of the fixed cross bar 3, and the T-slots 32 are perpendicular to the fixed cross bar 3. The bottom width of the T-slot 32 is greater than the slot width, the bottom width of the T-slot 32 is greater than the width of the rail bottom, the slot width of the T-slot 32 can be less than the width of the rail bottom, and the slot width of the T-slot 32 is greater than the thickness of the rail waist. The slot direction of the T-slot 32 is upward, and the distance between the two T-slots 32 on the fixed cross bar 3 is equivalent to the spacing between the two rails 2.

[0031] When the sleeper fixing frame is connected to the ballastless track, the rail bottom of the rail 2 extends into the T-shaped groove 32, and anti-skid pads 5 are respectively placed on the inner and outer sides of the rail waist, and the side of the anti-skid pad 5 is against the rail waist of the rail 2, and then the wedge block 4 is inserted between the anti-skid pad 5 and the side wall of the T-shaped groove 32, and the wedge block 4 can be hammered with a tool so that one side of the wedge block 4 is pressed against the anti-skid pad 5 and the other side is pressed against the side wall of the T-shaped groove 32. Through the above steps, the sleeper fixing frame and the ballastless track can be fixedly connected.

[0032] Wedge blocks 4 and wedge blocks 4 are required in both T-slots 32 to press against the inner and outer sides of the waist of the rail 2 , so as to fix the sleeper fixing frame and the two rails 2 .

[0033] In addition, a positioning hole 41 with an internal thread can be provided on the wedge block 4, and a waist-shaped hole can be provided on the anti-slip pad 5; then a screw is used to pass through the positioning hole 41 and the waist-shaped hole to press against the rail waist to reduce the probability of the wedge block 4 being loosened. When the wedge block 4 has a tendency to slide along the length direction of the rail 2, the nut part of the screw can be blocked by the fixed cross bar 3, thereby reducing the probability of the wedge block 4 falling off.

[0034] A scale 31 is provided on the outer wall of the middle part of the fixed crossbar 3. The scale 31 can be used to assist in determining the lateral adjustment distance of the ballastless track when adjusting the position.

[0035] The anti-skid pad 5 is provided with anti-skid grooves on one side facing the rail waist.

[0036] A guide groove is provided on one side of the anti-skid pad 5 facing the wedge block 4 , and a convex strip slidably matched with the guide groove is provided on one side of the wedge block 4 facing the anti-skid pad 5 .

[0037] When in use, generally a plurality of sleeper fixing frames are installed in the length direction of the rail 2. When the tool for assisting in adjusting the position of the ballastless track applies force, the force will directly act on the sleeper fixing frame, which reduces the risk of hidden damage to the ballastless track compared to directly acting on the ballastless track.

[0038] The above embodiments are merely examples for the purpose of clarifying the description, and are not intended to limit the implementation methods; it is not necessary and impossible to list all implementation methods exhaustively. However, obvious changes or modifications derived therefrom are still within the scope of protection of the present technology.
