Description

Technical Field

[0001] The utility model belongs to the field of lifting equipment, in particular to a high-efficiency double-row bucket weight tensioning type lifting machine. Background Art

[0002] As people pursue production efficiency, elevators are increasingly used in industrial production. Bucket elevators are a fixed mechanical conveying device that is mainly suitable for continuous vertical lifting of powdered, granular and small pieces of materials. They can be widely used in feed mills, flour mills, rice mills, oil mills, starch mills, grain depots, ports and docks of various sizes. As an important component of bucket elevators, if the conveyor belt cannot be kept in a tensioned state all the time, it will affect production efficiency and production safety. Existing patent CN 218617400 U discloses a tensioning device for a hoist tensioning wheel, comprising: a first mounting bracket and a second mounting bracket arranged opposite to each other, the first mounting bracket and the second mounting bracket being connected by an adjusting screw rod, a first connecting block being arranged on the outer side of the second mounting bracket, the first connecting block being a right-angle structure, the first connecting block comprising a first right-angle side and a second right-angle side, wherein the first right-angle side is connected to the second mounting bracket by a fastening bolt, the second right-angle side is connected to the second connecting block by a fastening bolt, a tensioning sprocket is installed on the second connecting block, and the first mounting bracket, the second mounting bracket and the second connecting block are respectively installed on the hoist frame by using T-bolts, the adjusting screw rod passes through the first mounting bracket, the second mounting bracket and the first right-angle side in sequence, and extends to the outside of the first right-angle side, the adjusting screw rod is provided with a first adjusting nut at the outer end of the first mounting bracket, the adjusting screw rod is provided with a second adjusting nut at the inner end of the first mounting bracket, a third adjusting nut is arranged on the inner side of the fastening bolt for connecting the first right-angle side and the second mounting bracket, and the adjusting screw rod is provided with a fourth adjusting nut at the outer end of the first right-angle side. This is a tensioning method used for elevators. Similar tensioning structures are usually more complicated or require additional energy to ensure the tension of the conveyor belt. With the continuous increase in production costs, people hope to find bucket elevators with lower equipment costs, lower operating costs, easier use, and better tensioning effects. Utility Model Content

[0003] The utility model aims to provide a high-efficiency double-row bucket weight tensioning hoist which does not require additional kinetic energy and can achieve real-time tensioning of a conveyor belt.

[0004] The utility model is realized by the following technical solutions:

[0005] An efficient double-row bucket weight tensioning elevator comprises a chassis and an upper driving wheel and a lower driving wheel which are arranged relatively up and down in the chassis, a conveyor belt for fixing the lifting basket is provided between the upper driving wheel and the lower driving wheel, the lower driving wheel is mounted on the chassis through a supporting shaft, both ends of the supporting shaft protrude out of the chassis, a lever frame which surrounds the outside of the chassis is fixedly connected via a pin shaft on an outer side surface of the chassis corresponding to the position where the lower driving wheel is located, the lever frame is pressed onto both ends of the supporting shaft which protrude out of the chassis, and a weight is provided on the other end of the lever frame which is opposite to the end connected and fixed with the chassis pin shaft.

[0006] Preferably, the lever frame is a U-shaped frame.

[0007] The beneficial effects of the utility model are:

[0008] The high-efficiency double-row bucket weight tensioning elevator of the utility model has an ingenious structure. By arranging a lever frame with a weight pressed on both ends of the support shaft where the lower drive wheel is located, the conveyor belt arranged between the upper and lower drive wheels can be tensioned in real time due to the gravity of the weight. The equipment has low cost, good control effect, strong practicality, and is worthy of promotion. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The present invention will be described by way of examples with reference to the accompanying drawings, in which:

[0010] Figure 1 A schematic diagram of the structure of the hoist according to an embodiment of the utility model;

[0011] Figure 2 for Figure 1 A magnified view of the lower structure;

[0013] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0014] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0015] like Figure 1-3As shown, a high-efficiency double-row bucket weight tensioning elevator comprises a chassis 1 and an upper driving wheel 2 and a lower driving wheel 3 which are relatively arranged in the chassis 1 from top to bottom, a conveyor belt 4 for fixing the lifting basket is provided between the upper driving wheel 2 and the lower driving wheel 3, the lower driving wheel 3 is mounted on the chassis 1 through a supporting shaft 5, both ends of the supporting shaft 5 protrude out of the chassis 1, and a lever frame 6 surrounding the outer side of the chassis is fixedly connected through a pin shaft on an outer side surface of the chassis 1 corresponding to the position where the lower driving wheel 3 is located, the lever frame 6 is pressed on both ends of the supporting shaft 5 protruding out of the chassis, and a weight 7 is provided on the other end of the lever frame 6 opposite to the end connected and fixed with the chassis pin shaft, i.e., the movable end.

[0016] The lever frame 6 is a U-shaped frame.

[0017] How it works:

[0018] Because the lever frame 6 is pressed on the two ends of the support shaft 5 protruding outside the chassis, and one end of the lever frame 6 is connected to the chassis 1 with a pin, and the movable end of the other end is connected to a heavy hammer 7, the lower drive wheel 3 can be pressed downward at all times through the gravity of the heavy hammer 7 to prevent the lack of tension between the upper drive wheel 2 and the lower drive wheel 3, thereby obtaining an automatic tensioning effect without the need for additional power.

[0019] The high-efficiency double-row bucket weight tensioning elevator of the utility model has an ingenious structure. By arranging a lever frame with a weight pressed on both ends of the support shaft where the lower drive wheel is located, the conveyor belt arranged between the upper and lower drive wheels can be tensioned in real time due to the gravity of the weight. The equipment has low cost, good control effect, strong practicality, and is worthy of promotion.

[0020] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
