Description

Technical Field

[0001] The utility model belongs to the technical field of material handling equipment, and particularly relates to a belt conveyor head for embedding a bin-matching scraper conveyor. Background Art

[0002] The belt conveyor and the scraper conveyor are connected together to form a conveying system, such as Figure 8 As shown, in the prior art, the drive part of the scraper conveyor is located above the coal bunker. According to feedback from the mine, the on-site scraper conveyor drive vibrates significantly. For safety reasons, it is necessary to extend the bunker scraper conveyor and move its drive backwards. The belt conveyor head and unloading need to be changed accordingly in design.

[0003] According to the characteristics of the horizontal throwing motion of the coal flow, in order to ensure the landing point of the coal flow, the distance L between the center of the unloading drum and the center of the coal bin must remain unchanged at 3000mm. In this way, there are many challenges. The difficulties are analyzed as follows: 1. If the position of the unloading drum remains unchanged and the unloading frame moves backward, the cantilever body supporting the unloading drum on the unloading frame will be more than 10m long, and the force strength is difficult to guarantee; 2. If the positions of the unloading drum and the unloading frame remain unchanged, there are two difficulties. First, there is serious interference between the belt and the scraper drive. It is obviously unrealistic to salvage the scraper head and return it to the factory for repair; second, if the scraper drive is completely embedded in Under the belt conveyor unloading frame, the original unloading frame obviously cannot meet the use requirements, and a large unloading structure needs to be redesigned; 3. According to the analysis of the scraper conveyor drive external dimensions, if the belt conveyor adopts a large unloading structure, its unloading frame support structure, that is, the unloading frame base, has an external dimension of approximately 5800mm×4400mm×2200mm. This is impossible for Chengzhuang Mine, which was built earlier, to go down the mine; 4. The center lines of the two conveying equipments, the silo scraper and the belt conveyor, form an acute angle of 6.42°. While ensuring that there is no interference with the drive of the scraper conveyor, it brings certain troubles to the design of the foundation of the unloading frame base.

[0004] Based on practical and cost considerations, it is crucial to design an efficient and reasonable solution for the connection between the scraper conveyor and the belt conveyor to avoid the need to salvage the equipment and repair it. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a belt conveyor head for embedding a bin scraper conveyor of the utility model in conjunction with the accompanying drawings.

[0023] like Figure 1 and Figure 2 As shown, a belt conveyor head for embedding a warehouse scraper comprises an unloading frame 12, an unloading roller 11 is installed at the front end of the unloading frame 12, the unloading frame 12 is installed on the unloading frame base 13, the unloading frame base 13 comprises a rectangular frame 131 for fixing the unloading frame 12, front columns 132 and rear columns 133 are respectively arranged at intervals below the front and rear ends of the rectangular frame 131, a side frame 134 is arranged below one of the left and right side ends of the rectangular frame 131, the head of the warehouse scraper 2 extends from between the front columns 132 to the bottom of the rectangular frame 131, and the other left and right side ends of the rectangular frame 131 are open for installing the scraper drive unit 21 of the warehouse scraper 2 to the bottom of the rectangular frame 131.

[0024] like Figure 3 As shown, the center lines of the bin-loading scraper 2 and the belt conveyor 1 form a certain angle with each other, and the scraper drive is arranged in a parallel axis. No support can be installed in the central area. Therefore, an asymmetric foundation 14 is preset for the unloading frame base 13 in the gap around the bin-loading scraper 2 drive, that is, five groups of column foundations are arranged in front of the head of the bin-loading scraper 2, three groups of single-column foundations are arranged at the rear, and a group of side frame foundations is arranged on the right wing (looking from the tail of the bin-loading scraper 2 to the head direction). In addition, in order to facilitate the lifting and installation of the drive motor and reducer of the bin-loading scraper 2, no supporting foundation is arranged on the left wing of the head.

[0025] like Figure 4~Figure 6 As shown, since the unloading frame base 13 is too large to be lowered into the well, it is initially split into: a rectangular frame 131, three groups of front columns 132, five groups of rear columns 133, and a side frame 134, which are connected by bolts. Except for the rectangular frame 131, the sizes of the other components can ensure that they can be lowered into the well. The rectangular frame 131 is split twice. The rectangular frame 131 is supported by the side frame 134, three groups of front columns 132, and five groups of rear columns 133 below. It is connected to the unloading frame 12 above and is subject to the tension of the connecting bolts. The maximum width of the component size for the mine to go down the well shall not be greater than 2200mm. Based on this, the rectangular frame 131 with an overall size of 5800mm×4400mm×440mm is split into 5800mm×4400mm×440mm. There are two sets of front and rear rectangular frames 131 with a size of 2200mm×440mm. The central area directly below the rectangular frames 131 is driven by the scraper. It is impossible to set up pillars in this area to provide support. In order to increase the strength, the two sets of rectangular frames are connected in the middle with double rows of high-strength bolts.

[0026] A jackscrew bracket 135 is provided at the rear end of the rectangular frame 131, and a jackscrew screw is threadedly connected to the jackscrew bracket 135, and the front end of the jackscrew screw is against the rear end of the unloading frame 12. The jackscrew device provided at the rear side of the unloading frame 12 can prevent the connecting bolts of the unloading frame 12 and the unloading frame base 13 from being damaged by shear force.

[0027] The left and right sides above the rectangular frame 131 are respectively provided with inclined rods 136, and the upper ends of the inclined rods 136 are respectively connected to the left and right sides of the unloading frame 12. The inclined rods 136 installed on the left and right sides of the unloading frame 12 can strengthen the fixation with the unloading frame base 13.

[0028] The bottom end of the rear column 133 is detachably fixed on the rear lower bottom beam 1331, and the rear lower bottom beam 1331 is fixed on the five groups of column foundations. The side frame 134 is a mountain-shaped structure, and the bottom is the side lower bottom beam 1341, which is fixed on the side frame foundation. The side frame 134 has symmetrically arranged diagonal braces inside.

[0029] like Figure 1 and Figure 7 As shown, the belt is wound around the unloading roller 11 in the running direction and then wound around the driven roller and the redirecting roller of the second driving unit 16 in sequence. Since the driven roller is located above and behind the redirecting roller, interference between the belt and the scraper driving unit 21 can be avoided.

[0030] like Figure 7~Figure 9 As shown, the existing belt conveyor can be modified, the first drive part 15 and the second drive part 16 of the belt conveyor 1 are interchanged, that is, the first drive part 15 is moved back to the second drive part 16, and the second drive part 16 is moved to the first drive part 15, and a set of steering parts 17 is added, and the belt is turned as shown in FIG. Fig. 9 The original winding method shown is changed to Figure 7 The winding method shown solves the problem of interference between the belt and the scraper drive unit 21.

[0031] In this embodiment, the winding method of the belt from the unloading part to the driving part of the belt conveyor is first changed, and then the unloading part is designed to be a combined steel structure of an unloading frame 12 and an unloading frame base 13. The unloading frame 12 is a part of the belt conveyor 1, and the unloading frame base 13 not only supports the unloading frame 12, but also wraps the scraper conveyor driving part 21 of the bin scraper 2, thereby perfectly connecting two different conveying equipment, the bin scraper 2 and the belt conveyor 1.

[0032] By cleverly changing the belt winding method, the interference problem between the belt and the bunker scraper drive is perfectly solved. A large rectangular frame-type unloading frame base 13 is used to embed the scraper drive as a whole into the belt conveyor unloading part. At the same time, the large rectangular frame-type unloading frame base 13 is reasonably and cleverly split to solve the problem that large steel structures cannot be lowered into the mine. Under the premise of ensuring the location of the drop point, it not only solves the mine's concerns about the obvious safety hazards caused by the drive vibration of the bunker scraper 2 above the coal bunker 3, but also opens up new ideas for the perfect connection of two conveying equipment such as the bunker scraper 2 and the belt conveyor 1, provides reliable technical support, and provides valuable experience for reference for the reliable and effective connection of conveying equipment, which has certain promotion value.
