Detailed Description
Embodiment 1, referring to the accompanying drawings, a frame comprises a driving shaft 3 and a driven shaft 4 which are pivoted at two ends of the frame 1, wherein the driving shaft 3 and the driven shaft 4 are wound with two chains 6 through chain wheels, the two chains 6 are fixedly connected through a plurality of connecting plates 8, and an endless belt 9 is wound outside the connecting plates 8; naturally, as in the prior art, a guide rail (not shown) is fixed to the frame 1 for each chain, said guide rail supporting the rollers of the chain 6. In this example, the connecting plate is connected to the outer link plate of the first chain by a screw. Of course, the link plates can also be screwed to all the outer link plates of the chain. The connecting plate can be connected to the inner link plate of the chain through screws.
The power generated by the hydraulic motor 2 drives the chain 6 to rotate through the driving shaft 3, and meanwhile, the connecting plate 8 is locked on the chain 6 and rotates along with the chain 6. An endless belt 9 is attached to the surface of the connecting plate 8 and wound between the driving shaft 3 and the driven shaft 4. When the chain 6 drives the connecting plate 8 to rotate, the endless belt 9 can move along with the chain under the action of friction force, so that the purpose that goods are automatically unloaded by the movement of the endless belt 9 is achieved. The connecting plate 8 and the endless belt 9 are not rigidly connected to each other, and power is transmitted therebetween by friction. The full load increases the friction between the web 8 and the endless belt 9 to meet the power requirements for unloading. Relative slip between the web 8 and the endless belt 9 may also occur under heavy or no load conditions to reduce belt damage.
In embodiment 2, on the basis of embodiment 1, an additional guide rail 7 is fixedly arranged on the frame 1 between the two chains 6, and the lower surfaces of the connecting plates 8 are in sliding fit with the additional guide rail 7. This can improve the loading capacity.
In embodiment 4, in addition to embodiment 1, driven shaft fixing plates 41 are respectively fixedly arranged on both sides of the frame 1, a long hole 43 having a length direction identical to that of the frame 1 is formed in each driven shaft fixing plate 41, a fastening screw penetrates through the long hole 43 and is fixedly connected to a driven shaft mounting plate 42, and the driven shaft 4 is pivotally arranged on the driven shaft mounting plate 42. Still do not the rigid coupling belt axle mounting panel 54 on the driven shaft fixed plate 41, belt axle mounting panel 54 sets firmly bearing slide 51, bearing slide 51's slip direction with frame 1's length is unanimous, with bearing slide 51 sliding fit slide bearing 52, belt tensioning axle 5 pivot is established on the slide bearing 52, connect adjusting bolt 53 on the slide bearing 52, the nut sets firmly on the frame 1, the nut with adjusting bolt 53 spiro union, no end belt 9 is around establishing on belt tensioning axle 5 and the driving shaft 3.
The position of the driven shaft mounting plate 42 can be adjusted within a certain range through the long hole on the driven shaft fixing plate 41, so that the distance between the driven shaft 4 and the driving shaft 3 is adjusted, and the purpose of tensioning the chain is achieved. While the belt shaft mounting plate 54 is mounted on the driven shaft mounting plate 42 so that the belt moves together while tensioning the chain. By rotating the adjusting bolt 53, the endless belt 9 can be tensioned without the chain 6 moving, so that there is sufficient friction between the connecting plate 8 and the endless belt 9.
