Description

Technical Field

[0001] The invention relates to the field of scraper conveyors, and in particular to a multi-point intelligent driven scraper conveyor. Background Art

[0002] As a transportation equipment for coal mine working face, the scraper conveyor not only undertakes the role of transporting coal, but also serves as the running track of the coal mining machine and the push fulcrum of the hydraulic support. At present, the scraper conveyor is generally equipped with two drive devices, which are arranged at the head and tail of the scraper conveyor respectively; the drive device transmits traction by pulling the scraper chain, overcomes various running resistances, and drives the scraper conveyor to run; the greater the resistance, the greater the tension of the scraper chain, the greater the traction required, and the greater the required motor power, which in turn causes an increase in power consumption; at the same time, the increase in tension also increases the strength requirements of the scraper chain, which leads to the thickening of the scraper chain. Moreover, the head and tail drive parts are large in size, causing problems such as lagging support at the end of the working face and insufficient pedestrian space. With the improvement of production efficiency of the fully mechanized mining working face, the installed power of the scraper conveyor is getting larger and larger. At present, the installed power can reach 3*1600KW. The smooth start and stable operation of the scraper conveyor under heavy load conditions are directly related to the failure rate, service life and production safety of the fully mechanized mining working face of the scraper conveyor, but it is difficult to achieve high reliability in reality.

[0003] Therefore, it is necessary to solve the above technical problems. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a multi-point intelligent drive scraper conveyor. The present invention creatively cancels the drive device at the head and tail of the scraper conveyor, and instead arranges the drive device on the middle groove. Multiple sprockets on the middle groove drive synchronously to provide power to drive the scraper chain to move, and finally play the role of transporting materials. The technical solution adopted by the present invention is as follows:

[0005] A multi-point intelligent driven scraper conveyor comprises a head frame assembly, a middle trough, a scraper chain and a tail frame assembly, wherein a plurality of middle troughs are provided, and the head frame assembly, the middle trough and the tail frame assembly are sequentially connected by dumbbell pins, the scraper chain starts from the head frame assembly, passes above the middle trough, reaches the tail frame assembly, and then rotates back to the head frame assembly through the tail frame assembly to form a closed chain, among the plurality of middle troughs, at least two middle troughs are installed with a driving structure to form a driven middle trough, the driving structure is eliminated inside the head frame assembly and the tail frame assembly, a sprocket assembly is also installed on the driven middle trough, the scraper chain is installed on the sprocket assembly, the driving structure drives the sprocket assembly to rotate, and further drives the scraper chain to run to deliver the material.

[0006] Furthermore, the driving middle groove is based on the middle groove and also includes a pressure block, a hexagon socket head screw and a nut. The top of the sprocket assembly is fixed to the middle groove by the pressure block, the hexagon socket head screw and the nut, and the two sides of the sprocket assembly are fixed to the middle groove by hexagonal head bolts.

[0007] Furthermore, an upper middle plate is arranged above the sprocket assembly, and both sides of the upper middle plate are fixed on the middle groove. Openings for the sprocket assembly to pass through are opened at both ends of the upper middle plate, and the sprocket assembly is adapted to be connected to the scraper chain through the opening.

[0008] Furthermore, the driving structure is a reduction motor, and the driving shaft of the reduction motor is fixedly connected to the central rotating shaft of the sprocket assembly, transmitting the driving force to the sprocket assembly and further to the scraper chain.

[0009] Furthermore, it also includes a pin rail, which is connected to the middle groove through a pin rail connecting pin and a stop pin.

[0010] Preferably, the pin rail is a side-hanging structure.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. In the present invention, through structural improvement, no driving structure is provided at the head and tail of the scraper conveyor, and the driving structure is distributed on the middle trough body instead, so that the tension of the scraper chain is reduced, the diameter of the chain is reduced, the traction force is reduced, and the energy consumption is greatly reduced, which is far superior to the existing technology.

[0013] 2. The present invention increases the pedestrian space at the nose and tail by improving the nose and tail, and the unloading height of the nose and tail can be reduced accordingly, reducing power loss. It is a new type of scraper conveyor with small size, large transport capacity and stable operation.

[0014] 3. The present invention is a multi-point drive. Due to the increase in the number of drives, the system can still operate normally even if less than 30% of the drive units fail, which greatly improves the overall reliability.

[0015] In summary, the present invention has an ingenious design and a reasonable structure and does not require much improvement on the prior art, which effectively improves the economic benefits of coal mines and has great promotion significance. BRIEF DESCRIPTION OF THE DRAWINGS
