Problems solved by technology

[0004] At present, the traditional rail clamps for rail cars only have outer wheels, which are directly fixed on the frame or bogie, and are respectively arranged on both sides of the rail car facing each other. The distance between them is Fixed, when the gauge changes, the outer card wheel and the rail will interfere violently, which will affect the service life of the outer card wheel and the rail, and also affect the normal operation of the rail car. The reliability is low and the operation of the rail car is low. safety is not guaranteed
[0005] In addition, the terrain in the mining area is complex, and the track laying depends on the terrain or steep slopes or sharp turns. The trucks are easily derailed, causing rollovers, causing property losses and even casualties to production.

Embodiment 1

[0051] In the above-mentioned two embodiments, the rail holder 30 is the same type, which is combined below Figure 5 to Figure 7 Describe it.

[0052] Such as Figure 5 to Figure 7 As shown, the rail clamp 30 includes a fixed seat 31 and a sliding seat 32, the fixed seat 31 is connected with the vehicle frame 10 or the bogie 11, and its connection can be through welding or mechanical connection, preferably a detachable connection; the bottom of the fixed seat 31 is concave The hollow forms a T-shaped slot, and the top of the sliding seat 32 protrudes through the bottom of the fixed seat 31 and the top protrusion of the sliding seat 32 in a "T"-shaped nesting connection. The T-shaped slot is used as a guide groove, and the sliding seat 32 can be relatively fixed. Seat 31 slides left and right.

[0053] The sliding seat 32 has an integrated structure, the middle part is hollow and penetrates left and right, and the bottom is connected with a clamp, preferably left and right v...

Embodiment 4

[0063] Such as Figure 12 and Figure 13 As shown, the cross-section of the fixing seat 31 is positive T-shaped, wherein the lower circular guide hole penetrates left and right; the cross-section of the outer sliding seat 322 and the inner sliding seat 321 is L-shaped, wherein the upper circular fixing hole penetrates left and right, and they are opposite to each other. It is arranged on the left and right sides of the fixed seat 31; the slide bar 324 passes through the guide hole, and the outer slide seat 322 and the inner slide seat 321 are respectively fixed at the two ends of the slide bar 324. The slide bar 324 is preferably straight cylindrical, and the diameter of the guide hole Adapt to the diameter in the middle of the slide bar 324, the diameter of the fixing hole is adapted to the diameter of the two ends of the slide bar 324, preferably the diameter of the guide hole is greater than the diameter of the fixing hole, so that the two ends of the slide bar 324 can be m...

Embodiment 5

[0066] Such as Figure 14 and Figure 15 As shown, the cross section of the fixing seat 31 is concave, and the left and right side walls are respectively provided with circular fixing holes; the outer sliding seat 322 and the inner sliding seat 321 are against each other, and are fixedly connected to the upper part by screws 323 , the four corners are preferably distributed and fixedly connected by four screws 323, and the four screws 323 are preferably distributed in a positive trapezoidal shape. A circular sliding hole is provided at the center of the trapezoid, and the sliding hole penetrates the upper part of the outer sliding seat 322 and the inner sliding seat 321. And corresponding to the fixed hole, the guide rod 327 passes through the above-mentioned sliding hole, and its two ends respectively pass through the fixing hole and then fixed. The guide rod 327 is preferably straight cylindrical, and the diameter of the slide hole is compatible with the diameter in the midd...

Abstract

The invention provides a rail clamping device and a rail vehicle thereof. The rail clamping device comprises a fixed seat, a sliding seat and a clamping piece, wherein the fixed seat and the sliding seat form a transverse moving pair; the sliding seat is fixedly connected with the clamping piece; the clamping piece comprises an outer clamping piece and an inner clamping piece; the distance between the outer clamping piece and the inner clamping piece is fixed relatively so that the outer clamping piece, the inner clamping piece and the bottom of the sliding seat form a rail clamping cavity; the cavity is used for accommodating a rail head so that the inner side of the clamping piece limits the left side and the right side of the rail head. The rail vehicle comprises the rail clamping device. The sliding seat can slide in the left-right direction relative to the fixed seat. When the rail vehicle runs on steel rails, the distance between two opposite outer clamping pieces is adjusted automatically; by the split sliding seat, the detachable clamping piece, a flange, chamfering and a sliding rod, the rail clamping device is used flexibly, mounting, detaching and changing are facilitated, and wear of various parts is improved meanwhile. The service life is long, and the reliability and the safety are high.

Description

technical field [0001] The invention relates to a rail gripper and a rail gripper thereof. Background technique [0002] With the development of the railway transportation industry, people have higher and higher requirements for the safety and performance of the vehicles running on the rails. [0003] At present, as a type of railway transport vehicle, truck rail cars have been widely used in the transportation of materials and personnel in complex sections, and in mining areas with large production capacity. [0004] At present, the traditional rail clamps for rail cars only have outer wheels, which are directly fixed on the frame or bogie, and are respectively arranged on both sides of the rail car facing each other. The distance between them is Fixed, when the gauge changes, the outer card wheel and the rail will interfere violently, which will affect the service life of the outer card wheel and the rail, and also affect the normal operation of the rail car. The reliabil...
