Abstract
Description
Technical Field
[0001] This utility model relates to the field of transfer machine technology, and in particular to a central trough for a transfer machine. Background Technology
[0002] In underground coal mining and transportation systems, the transfer conveyor, as a core hub connecting the face scraper conveyor and the roadway belt conveyor, directly determines the continuity and stability of the coal transportation system. Traditional transfer conveyors use an integrated, fully enclosed steel structure top cover for the central trough. While this structure effectively prevents coal dust spillage, it has significant technical drawbacks: First, the enclosed box structure completely obscures the visibility of the scraper chain's trajectory, preventing inspectors from real-time monitoring of key parameters such as the scraper chain's operating status, scraper deformation, and chain slack. Second, phenomena such as lump coal jamming and coal accumulation on the bottom of the chain track during coal transportation are difficult to identify through external observation. Daily maintenance requires repeated opening and closing of the top cover, resulting in lengthy disassembly and assembly operations, and frequent bolt tightening can easily cause structural fatigue in the connecting components. More seriously, the enclosed space easily forms a coal dust accumulation zone, posing a potential risk of deflagration. This design flaw not only reduces the efficiency of equipment fault diagnosis but also increases the average annual unplanned downtime, severely hindering efficient coal mine production.

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0040] like Figures 1 to 5 As shown, this utility model includes two opposing troughs 1, with a middle plate 2 and a cover plate 3 between the two troughs 1. The middle plate 2 divides the space between the two troughs 1 vertically to form a coal conveying space 11 and a chain conveying space 12. The cover plate 3 is installed on the top of the troughs 1 and covers the two troughs 1. An upper movable baffle assembly 4 and a lower movable baffle assembly 5 are installed on the troughs 1. The upper movable baffle assembly 4 is set corresponding to the coal conveying space 11 and is used to connect or close the coal conveying space 11 to the outside. The lower movable baffle assembly 5 is set corresponding to the chain conveying space 12 and is used to connect or close the chain conveying space 12 to the outside. When it is necessary to check the coal blockage in the coal conveying space 11, the upper movable baffle assembly 4 is opened for inspection. After the inspection is completed, the upper movable baffle assembly 4 is closed, which will not affect the normal coal conveying of the coal conveying space 11. Similarly, when it is necessary to check the operation of the scraper chain, the lower movable baffle assembly 5 is opened to check the conveyor space 12. After the inspection is completed, the lower movable baffle assembly 5 is closed, which will not affect the internal scraper chain and ensures the stability of operation.
[0041] A stiffening rib assembly 6 is fixedly installed on the trough body 1, and an upper movable baffle assembly 4 is positioned above the stiffening rib assembly 6. The stiffening rib assembly 6 enhances the strength of the trough body 1 and ensures that its structural strength is not affected by the installation of the upper movable baffle assembly 4 and the lower movable baffle assembly 5, thus guaranteeing the normal operation of the middle trough of the transfer machine.
[0042] In this application, the upper movable baffle assembly 4 and the lower movable baffle assembly 5 have the same structure; both include a baffle 41, a mounting plate 42, and a connecting assembly 43. The groove 1 has an operating through hole 13 for accommodating the baffle 41. The mounting plate 42 is fixedly disposed on the outside of the baffle 41 and is used for fixed connection with the groove 1. The connecting assembly 43 is used to install the mounting plate 42 onto the groove 1. When the mounting plate 42 is fixedly connected to the groove 1, the baffle 41 is accommodated within the operating through hole 13, thus filling the operating through hole 13.
[0043] Preferably, there are two identical connecting components 43, which are horizontally positioned on opposite sides of the mounting plate 42. Each connecting component 43 includes a mounting pin 431, a hanging ear 432, a hanging hole 433, and a pin 434. The mounting pin 431 is fixed to the groove 1 and perpendicular to its plane. The hanging ear 432 is integrally formed into the mounting plate 42, and the hanging hole 433 is formed in the hanging ear 432. The distance between the centers of the two hanging holes 433 is 360mm. The pin 434 is inserted into the mounting pin 431, and the mounting pin 431 has a corresponding insertion hole. When the mounting pin 431 passes through the hanging hole 433, the pin 434 engages with the insertion hole, fixing the mounting plate 42 to the groove 1 for easy assembly and disassembly.
[0044] In this application, the baffle 41, mounting plate 42, and operating through hole 13 are all rectangular. The length and width of the baffle 41 are smaller than those of the mounting plate 42. The thickness of the baffle 41, the thickness of the mounting plate 42, and the thickness of the groove 1 are all the same. The fact that the thickness of the baffle 41 is the same as that of the groove 1 can prevent the scraper from scratching or jamming.
[0045] A handle 44 is fixedly provided on the mounting plate 42. The handle 44 is vertically arranged and located at the center of the mounting plate 42. When the mounting plate 42 is removed from the tank body 1, it is convenient to grasp the mounting plate 42 with one hand by using the handle 44, while the other hand can operate the water pipe to flush the coal blockage in the coal conveying space 11. Preferably, the length of the mounting plate 42 is 310 mm and the width of the mounting plate 42 is 198 mm.
[0046] In this application, the stiffener assembly 6 includes a horizontal stiffener 61 and a plurality of longitudinal stiffeners 62; wherein the horizontal stiffener 61 is horizontally arranged and its two ends are bent downward, the longitudinal stiffeners 62 are fixed below the horizontal stiffener 61, and the plurality of longitudinal stiffeners 62 are arranged at equal intervals along the horizontal direction.
[0047] Preferably, a groove side 63 is fixedly provided on the groove body 1. The groove side 63 is located below and fixedly connected to the longitudinal stiffener plate 62. Two vertical plates 64, which are fixedly connected to the groove body 1, are provided below the groove side 63. The lower movable baffle assembly 5 is located between the two vertical plates 64. The vertical plates 64 protect the lower movable baffle assembly 5, preventing damage to the pin 434 and preventing the mounting plate 42 from falling off the groove body 1 and affecting the normal operation of the scraper chain in the conveyor space 12. The upper movable baffle assembly 4 is located relatively high, so it does not need to be protected by other protective structures.
[0048] The upper movable baffle assembly 4 and the lower movable baffle assembly 5 have the same structure. The working principle will be described below using the upper movable baffle assembly 4 as an example.
[0049] When it is necessary to check the coal conveying space 11 in the trough 1 for coal blockage, after pulling out the pin 434, the mounting plate 42 is removed from the trough 1 by using the handle 44. The situation in the coal conveying space 11 can then be observed through the corresponding operating through hole 13. If there is coal blockage, it can be dealt with using external tools. After the blockage is completed, the mounting plate 42 is installed on the trough 1 through the hanging hole 433 and the mounting pin 431, and then the pin 434 is inserted into the mounting pin 431.
[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
