[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1-2As shown in the figure, a short-range energy-saving material conveying device for narrow spaces includes two front legs 1, a pneumatic motor 3, four supports 4, four sprockets 5, two rotating shafts 6, two chains 7, two cross beams 8, a support plate 9, several driving rods 10, and two rear telescopic legs 12. The two front legs 1 and the two rear telescopic legs 12 are vertically arranged on the front and rear sides respectively. The two front legs 1 are connected by a first cross beam bracket 2, and the two rear telescopic legs 12 are connected by a second cross beam bracket 13. The four supports 4 are respectively hinged to the upper ends of the two front legs 1 and the two rear telescopic legs 12. The two cross beams 8 are horizontally arranged in parallel, and the two ends are respectively fixedly connected to the supports 4 on the front legs 1 and the rear telescopic legs 12. A number of "U"-shaped reinforcing rods 11 are evenly fixed between the two cross beams 8. The reinforcing rods 11 in the middle are respectively hinged to the middle parts of the first cross beam bracket 2 and the second cross beam bracket 13 through telescopic rods 14. One rotating shaft 6 is arranged between the top surfaces of the two front supports 4 on the front side, and the other rotating shaft 6 is arranged between the top surfaces of the two rear supports 4 on the rear side. The four sprockets 5 are respectively fixed on both sides of the two rotating shafts 6. The sprockets 5 at the same side of the front leg 1 and the rear telescopic leg 12 are connected by a chain 7. The support plate 9 is laid between the two cross beams 8. A number of driving rods 10 are fixedly arranged in parallel between the two chains 7. The pneumatic motor 3 is arranged on one of the front legs 1, and the output shaft of the pneumatic motor 3 is connected to one end of the rotating shaft 6. The lower part of the pneumatic motor 3 is bound to the front leg 1 through a fixture 16.

[0021] The working process of the present utility model:

[0022] When withdrawing hydraulic supports in the fully mechanized coal mining face underground in a coal mine and conveying timbers to the triangular area for timber bracing operations, place the present utility model in the restricted space passage where materials need to be conveyed. The front legs 1 face the material accumulation area, and the rear telescopic legs 12 face the timber bracing operation area. When horizontal material conveyance is required, adjust the height of the rear telescopic legs 12 to be the same as that of the front legs 1. Fix the lower part of the pneumatic motor 3 with the fixture 16, and connect the external underground compressed air supply as the power source. Start the pneumatic motor 3 to drive the rotation of the rotating shaft 6 and the sprocket 5 on one side of the front leg 1, and drive the rotation of the sprocket 5 on the side of the rear telescopic leg through the chain 7. At this time, place the material 15 on the support plate 9, with one end against the rear driving rod 10 and the other end resting on the front driving rod 10. The driving rod 10 moves forward along with the chain 7, pushing the material 15 forward. When reaching the tail of the present utility model, the material 15 drops. Repeat the above process and continuously place the material 15 to achieve rapid material conveyance.

[0023] When it is necessary to transport materials to a higher place, the clamp 16 is unlocked, the height of the rear telescopic legs 12 is adjusted, and they are extended to the specified height and fixed. Then, the pneumatic motor 3 is fixed with the clamp 16. At this time, the utility model forms a shape with the front lower and the back higher. Repeat the above steps and continuously place the materials 15 to realize the rapid transportation of materials to a higher place.

[0024] By adjusting the volume of the underground pressure air supply, the speed of the pneumatic motor 3 can be adjusted, and thus the speed of conveying materials can be adjusted;

[0025] The arrangement of the first crossbeam support 2, the reinforcement rod 11, the second crossbeam support 13 and the telescopic support rod 14 can all enhance the stability of the device during operation.
