Detailed Description
The embodiments of the present invention will be further described with reference to the accompanying drawings so as to facilitate the further understanding of the present invention by those skilled in the art, and do not constitute a limitation to the right thereof.
The device is a dustproof device for attaching powdery goods to an automobile, and is shown in the attached figures 1-4,
including installing discharge hopper 1 on the support frame, the support frame is four stands, and the upper end of four stands links to each other with four fixed angles of discharge hopper 1, and the lower part of four stands is equipped with the reinforcement stull, and discharge hopper 1's below sets up to connect the goods district, and the carriage of freight train can remove the entering and connect the goods district.
Two parallel rails 2 are arranged on two sides of the discharging hopper 1, two sets of rail wheels 6 are arranged on each rail 2, four wheel bodies are arranged in each rail wheel 6, every two wheel bodies are coaxially arranged, and a motor driving mechanism for driving one set of wheel bodies is arranged on each rail wheel 6. The length of the track 2 is slightly larger than the sum of the length of the carriage and the track width of the two sets of track wheels 6. The track 2 is hung with a cuboid dust cover matched with the upper opening of the carriage through a track wheel 6, and the upper end of the dust cover is connected with the discharge hopper 1, so that the discharge hopper 1, the dust cover and the carriage form a closed space.
The dust cover has the following specific structure: the dust cover is provided with a dust cover body and a traction mechanism for traction the dust cover body to lift. The dust cover body is provided with a frame body which is communicated up and down and filter cloth sleeved on the frame body, and the filter cloth is dust suppression filter cloth. The frame body comprises an upper frame 9 and a lower frame 8 which are arranged up and down, and four corners of the upper frame 9 and the lower frame 8 are connected through long chains 5. The long chain 5 can be used for contracting the dust cover body and enhancing the strength of the filter cloth. The filter cloth is provided with a side filter cloth 10 wrapping the periphery of the frame body and a top filter cloth 3 arranged on the top surface of the frame body. The top surface filter cloth 3 is organ type filter cloth, two sides of the top surface filter cloth 3 are fixed on the upper frame 9 in a sliding mode through pulleys, and a feed inlet which is in butt joint with the discharge hopper 1 is formed in the top surface filter cloth 3. The side filter cloth 10 is connected at an upper portion thereof to the upper frame 9 and at a lower portion thereof to the lower frame 8.
The upper frame 9 is a rectangular frame structure, two metal sections in the length direction of the upper frame are channel steel, and the metal sections at two ends are square tubes. The two channel steels are oppositely arranged to form a sliding chute of the organ type top surface filter cloth 3, the rail wheels 6 can be fixed on the upper surfaces of the channel steels, and pulleys on two sides of the organ type top surface filter cloth 3 are fixed in the sliding chute. The flexible connection between the dust cover and the discharge hopper 1 can be realized by using the organ type top surface filter cloth 3, when the dust cover slides along the track 2 along with the carriage, the organ type top surface filter cloth 3 moves in the chute to stretch, and the organ type top surface filter cloth 3 can automatically fold and stretch according to the displacement of the dust cover, so that the discharge hopper 1 is always in butt joint with the feed inlet of the upper cover body.
The lower frame 8 is a rectangular structure formed by welding square pipes, and the size of the lower frame 8 is slightly smaller than that of the upper opening of the carriage, so that the lower frame is positioned in the carriage. When the dust cover falls down, the lower frame 8 just falls on the upper opening of the carriage, and the carriage can drive the dust cover to move horizontally.
The lower bottom edge of the side filter cloth 10 is connected with a skirt filter cloth 4 which extends downwards and is stretched outside a carriage. And a counterweight rod 12 is arranged on the lower edge of the skirt filter cloth 4, and the counterweight rod 12 is a metal rod. The skirt filter cloth 4 can be tightly attached to the upper opening of the carriage under the action of the gravity of the counterweight rod 12 by using the counterweight, so that the upper opening of the carriage is in sealed butt joint with the lower edge of the dust cover, and dust leakage is prevented.
The traction mechanism comprises winches which are respectively arranged in the middle of the four edges of the upper frame 9, and each winch is connected with the middle of the counterweight rod 12 of the skirt filter cloth 4 through a traction rope. Two ends of each side of the lower frame 8 are respectively connected with a pull rope 11, the other ends of the two pull ropes 11 positioned at the same side are connected with the joint of the side traction rope 7 and the counterweight rod 12, and the pull ropes 11 can be used for preventing the skirt from being damaged due to too large stress. The distance between the traction ends of the two winches arranged on each opposite surface is slightly larger than the size of the upper opening of the carriage, and the joint of the traction rope 7 and the counterweight rod 12 is subjected to oblique and outward pulling force. When the lower frame 8 is pulled by the pulling rope 7 to move up and down, the lower edge of the skirt-shaped filter cloth 4 is unfolded towards the periphery under the action of oblique outside force, so that the skirt-shaped filter cloth 4 is prevented from being pulled by a carriage.
Under normal conditions, the dust cover body is pulled up and is taken up, and when taking up, the hoist engine starts rolling haulage rope 7, draws up shirt rim filter cloth 4 earlier under the effect of traction force, then draws down lower frame 8 and whole dust cover body under the combined action of haulage rope 7 and stay cord 11 again. When the filter cloth is put down, the lower frame 8 and the filter cloth can be put down by loosening the traction rope 7.
The device hoists and folds the dust cover on the track 2 of the discharge hopper 1 through the track wheel 6, and the original position of the dust cover refers to the position of the upper opening of the boxcar when the foremost part of the boxcar receives materials. When the dust cover starts to work, when a truck drives into the material receiving area, the truck is parked behind the original position of the dust cover. The lower frame 8 of the dust cover is put down by the winding engine through the traction rope 7 to be in butt joint with the inner side of the upper opening of the carriage, then the skirt filter cloth 4 and the counterweight rod 12 thereof continue to move downwards, because the size of the lower frame 8 is smaller than that of the upper opening of the carriage, the distance between the traction ends of the two winding engines arranged on each opposite surface is slightly larger than that of the upper opening of the carriage, the skirt filter cloth 4 extends outwards and is stretched outside the carriage under the action of the gravity of the counterweight rod 12, and thus the discharge hopper 1, the dust cover and the carriage form a closed space. When receiving materials, the carriage starts to sequentially receive the materials from the most front part backwards, the dustproof cover synchronously moves on the track 2 in the moving process of the carriage, and meanwhile, the organ type top surface filter cloth 3 moves in a timely telescopic mode along with the movement of the carriage, so that the feed inlet of the organ type top surface filter cloth is always in butt joint with the discharge hopper 1. After completion, the winch is used for enabling four surfaces of the lower portion of the dust cover to rise simultaneously, then the rail wheel motor driving mechanism and the winch switch are operated in a linkage mode, the dust cover is enabled to retreat to the original position along the rail 2, the photoelectric limit switch is arranged on the rail 2 at the original position of the dust cover, and the position of the dust cover retreating along the rail 2 can be controlled.
This device is fit for the carriage of different grade types such as long car, short car and uses, and the dust cover docks with the carriage all the time simultaneously, the slippage can not appear or cover incomplete problem to it is effectual to realize dustproof, convenience simple to use.
