Abstract

The utility model relates to an inserted ladder track which is a ladder like mine haul track without the materials of the crosstie, the spike, the fish-plate, the screw, etc. The two tracks arranged in parallel are welded by the connecting plates, used for the controlling of the dimension of the distance between the tracks and used to replace the crossties. The eudipleural sockets and plugs are welded in the outside grooves of the alpha and omega of the two tracks for the lateral positioning, the internode connection and the holding of the lateral force. The design of the product is reasonable, the structure is simple and safe; the time, the people and the cost of the loading and the unloading are saved; because the crossties are replaced by the steel plates, so the center of gravity of the transporting is low, and is favorable to the quality standardizing and the well security. The utility model is an ideal new replacement product of the traditional well transporting tracks.

Description

Plug-in type ladder rail

The utility model belongs to a kind of ore deposit and conveying track.

At present, the mine conveying track is that track is placed on the sleeper, with compositions that tightens together such as railway spike, splice bar, bolts.Its shortcoming is: consumption of wood is big; Mounting or dismounting, maintenance, auxiliary materials expense cost height, labour intensity are big; The transportation difficulty; Reclamation rate is low; Easy flashing is unfavorable for downhole safety during spiking.

The purpose of this utility model is that design is a kind of without timber, mounting or dismounting convenient transportation, safe and reliable mine conveying track.

The utility model proposes of task is finished by following measure: track is cut into 2.5～4 meter one joint, and the track after will cutting with junction plate (steel plate) is welded into ladder-shaped, with the control gauge, replaces sleeper.On ladder shape track two lateral surface groove tops, the bilateral symmetry shape socket that is connected; At groove bottom, the other end two sides bilateral symmetry bar shaped latch that is connected.Latch and socket all have the arc surface of same radius, connect the center of circle, back not on one point.During connection, latch is inserted in the last joint ladder rail socket, finish internode and connect and located lateral, replace splice bar and bolt etc., form plug-in type ladder rail.

Owing to take above measure, the utility model has following advantage compared to existing technology:

1. steel plate replaces sleeper, saves a large amount of these materials.Without spiking, can flashing, be beneficial to downhole safety.

2. latch, socket replace splice bar, bolt etc., and mounting or dismounting are convenient, save aid.

3. cost is low, and particularly product life cycle cost is low.

4. help quality standardization.

5. convenient transportation.

6. the transportation center of gravity is low.

Following accompanying drawing has been described an embodiment of the present utility model.

Fig. 1 is the front view of a joint ladder rail.

Fig. 2 is the johning knot composition between the ladder rail.

In Fig. 1, two tracks 1 (18kg/m) be arranged in parallel, and length is 3 meters.Junction plate 2 usefulness steel plate (A ₃) make, be cut into strip and be welded between two tracks, with control gauge size and track rigidity.5 of every joint ladder rail welding.

In Fig. 2, socket 4 and latch 3 usefulness steel material A ₃Mold pressing is made, the head and the tail outside that is welded on every joint ladder rail is groove up and down, matching on shape and its curved surface, inclined-plane with the track contact portion, aligns with the track end face in the socket front, and soffit is the arc surface along the track direction.About three/the part of latch is stretched out the track end face, and the extension upper and lower surface is the arc surface along the track direction, and last arc surface is identical with arc surface radius under the socket, but connects the center of circle, back not on one point.

During installation, lift ladder rail one end (about 600m/m), use the latch (or socket) of the other end to insert in the socket (or latch) of last joint ladder rail, promptly finish internode and connect.So, can finish the installation of whole conveying track.

The utility model effect is fairly obvious, calculates 3 myriametre ladder rails through use and side, and the product life cycle can be reduced expenses 668.64 ten thousand yuan.

Claims

1. one kind by track, the plug-in type ladder rail that connector is formed, belong to ore deposit and conveying track, it is characterized in that, track is connected to form by the ladder shape track of 2.5～4 meters at some joints, every joint ladder shape track comprises two parallel rails 1, be connected 4～7 middle junction plates 2 of two tracks, junction plate is made the sleeper that replaces in the existing track of steel plate, symmetry is connected in two piece shape sockets 4 on groove top, the two tracks same end outside, and symmetry is connected in two bar shaped latches 3 of groove bottom, the two track other ends outside.

2. plug-in type ladder rail according to claim 1, it is characterized in that: piece shape socket is connected in groove top, the track outside, and identical with the track contact shape, front and the alignment of track end face, soffit is the arc surface along the track direction.

3. plug-in type ladder rail according to claim 1 and 2, it is characterized in that: the bar shaped latch is connected in groove bottom, the other end outside, about 1/3rd length are stretched out the track end face, latch and track contact position shape are coincide, the extension upper and lower surface is the arc surface along the track direction, last arc surface is identical with arc surface arc radius under the socket, but connects the center of circle, back not on one point.
