Description
Technical Field
The invention relates to firework equipment, in particular to a material trolley special for a firework drying room.
Background
In firework production, materials in a firework drying room are inflammable and explosive, cannot be rubbed and cannot collide, and the transportation of the materials is carried by a hand shoulder, so that the labor intensity is high, the production efficiency is low, and safety accidents can be caused by slight carelessness. At present, the trolley is also used for transferring materials, but the trolley is not provided with a device for limiting the steering of universal wheels and a reliable fixed wheel brake device, so that the walking direction and the walking speed can not be well controlled during operation, and great potential safety hazards exist.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides the special material trolley for the firework drying room, which has the advantages of simple structure, high production efficiency, safety and reliability.
The invention adopts the following technical scheme.
The utility model provides a special material dolly of fireworks baking house, has automobile body, tight pulley and universal wheel, still has tight pulley brake equipment and universal wheel stop device:
the fixed wheel braking device is provided with a guide rod which is arranged in the guide sleeve, the front end of the guide rod is fixedly provided with a brake block, the rear end of the guide rod is connected with the reciprocating machine, the guide sleeve is fixed on the vehicle body, and a pressure spring is arranged between the brake block and the guide sleeve;
the universal wheel limiting device is provided with a rotating shaft, the rotating shaft is arranged in the rotating sleeve, the rotating sleeve is fixed on the vehicle body, the rotating shaft is connected with the swinging mechanism, the rotating shaft is positioned above the universal wheel top plates, two limiting rods are respectively fixed at two ends of the rotating shaft, when the rotating shaft rotates in one direction, the two limiting rods at two ends of the rotating shaft respectively clamp the two universal wheel top plates, and when the rotating shaft rotates in the other direction, the two limiting rods at two ends of the rotating shaft respectively leave the two universal wheel top plates.
The fixed wheel and the universal wheel are made of antistatic plastics, and the brake pad is made of antistatic plastics or antistatic rubber.
The material of the car body is stainless steel.
Compared with the prior art, the novel material trolley has the advantages of simple structure and high reliability, and can stop the material trolley in situ at any time, thereby eliminating potential safety hazards.
Drawings
Fig. 1 is a schematic structural diagram of a novel embodiment of the present invention.
Fig. 2 is a schematic view of the elevation sectional view of fig. 1.
FIG. 3 is a schematic view of a portion of a universal wheel restraint.
Detailed Description
The invention is described in further detail below with reference to the drawings and examples.
As shown in fig. 1-3, a special material trolley for a firework drying room comprises a trolley body 16, a fixed wheel 5, a universal wheel 10, a fixed wheel brake device and a universal wheel limiting device:
the fixed wheel braking device is provided with a guide rod 3 which is arranged in the guide sleeve 2, the guide sleeve 2 is fixed on the vehicle body 16, the vehicle body 16 is made of stainless steel, a brake block 6 is fixed at the front end of the guide rod 3, the brake block 6 is made of antistatic rubber, a pressure spring 4 is arranged between the brake block 6 and the guide sleeve 2, the rear end of the guide rod 3 is fixed with one end of the short steel wire rope 1, the other end of the steel wire rope 1 is fixed with one end of the rocking plate 7, the middle part of the rocking plate 7 is hinged with the vehicle body 16, the other end of the rocking plate 7 is fixed with the long steel wire rope 18, the other end of the long steel wire rope 18 bypasses the middle guide wheel 8, the side guide wheel 9 is fixed with the brake rotating arm 19, and one end of the brake rotating arm 19 is hinged with the vehicle body 16. Normally, the brake pad 6 presses the fixed wheel 5 under the action of the pressure spring 4.
The universal wheel limiting device is provided with a rotating shaft 14, the rotating shaft 14 is arranged in a rotating sleeve 15, the rotating sleeve 15 is fixed on a vehicle body 16, the rotating shaft 15 is positioned above a universal wheel top plate 11, the universal wheel top plate 11 and a support of the universal wheel 10 are integrated, two limiting rods 12 are respectively fixed at two ends of the rotating shaft 15, and one end of the rotating shaft 14 is fixed with a sloping plate 13. One end of the connecting rod 17 is hinged with the inclined plate 13, the other end of the connecting rod 17 is hinged with the limiting rotating arm 20, and one end of the limiting rotating arm 20 is hinged with the vehicle body 16. Normally, the limiting rod 12 clamps the top plate 11 of the universal wheel vertically downwards under the action of gravity, and when the limiting rotating arm 20 rotates anticlockwise, the limiting rod 12 leaves the top plate 11 of the universal wheel.
