Embodiment 1

[0043] (Embodiment 1, one of rail car)

[0044] See figure 1 and figure 2 , The rail car of the present embodiment is a 4-wheel type rail car, including a vehicle frame 10, wheels 20 and a rail device 30. There are 4 rail holders 30, which are respectively located at the front end of each front wheel and the rear end of each rear wheel in the direction of travel of the rail car. Each rail clamp 30 is fixed on the vehicle frame 10 by welding. The rail car runs on the steel rail 40. The rail 40 includes a rail head 401 , a rail web 402 and a rail bottom 403 , and its cross section is I-shaped.

Embodiment 2

[0045] (Embodiment 2, the second of the rail car)

[0046] See image 3 and Figure 4 , The rail car of the present embodiment is an 8-wheel type rail car, including a vehicle frame 10, a bogie 11, wheels 20 and a rail device 30. There are 2 bogies 11, and 8 wheels 20 and rail clamps 30. The vehicle frame 10 is installed on two bogies 11 . Each bogie 11 is provided with 4 wheels 20, and 8 rail clamps 30 are respectively located at the front end of each front wheel and the rear end of each rear wheel on the bogie 11 in the traveling direction of the rail car. Each rail holder 30 is fixed on the bogie frame 11 by welding.

Embodiment 3

[0047] (Embodiment 3, one of the rail clamps)

[0048] The rail holder 30 in the above-mentioned two embodiments is the same type, combined below Figure 5 to Figure 7 Describe it.

[0049] See Figure 5 to Figure 7 , The rail clamp 30 includes a fixed seat 31 and a sliding seat 32 . The fixing seat 31 is connected with the frame 10 or the bogie 11 . Its connection can be through welding or mechanical connection, preferably detachable connection. The bottom of the fixing base 31 is hollow to form a T-shaped groove. The top of the slide seat 32 is convex. Through the hollow at the bottom of the fixing seat 31 and the protrusion at the top of the sliding seat 32, the two are nested and connected in a "T" shape. The T-shaped groove of the fixed seat 31 is used as a guide groove, and the sliding seat 32 can slide left and right relative to the fixed seat 31 .

[0050] The sliding seat 32 is an integral structure, the middle part is hollow and runs through from left to right...

Abstract

The invention relates to a rail clamping device for a common rail clamping car in a mining area and the clamping device thereof. The rail clamping device includes a fixed seat, a sliding seat and internal and external clamping parts. The sliding seat can slide left and right relative to the fixed seat to form a lateral movement pair. The inner and outer clips all include a card wheel shaft and a card wheel connected in rotation. The upper part of the outer card wheel and the inner card wheel are in the shape of a straight cylinder, and the lower part of the outer card wheel extends downwards and the bottom end is provided with an annular flange. The inner and outer clips are fixed on the sliding seat by the upper part of the respective card wheel shaft, and form a rail cavity for accommodating the rail head with the bottom of the sliding seat; The second is that the annular flange of the outer card wheel then limits the bottom side of the rail head; so that when the rail cars with the above-mentioned rail clamps are set in pairs, the distance between each two relative outer clamps The spacing adjustment range is large, and it can run on ordinary rails with large gauge changes, small horizontal turning radius, or yin and yang rails and other harsh working conditions, and has high reliability and safety.

Description

technical field [0001] The invention relates to a rail clamping device for a rail car in a mining area of ​​common rails and the rail car. 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 th...
