Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, and in particular to a novel protective device for preventing rock spillage on a mining scraper conveyor. Background Technology

[0002] In the coal mining process, the scraper conveyor is a key piece of equipment for coal transportation. Its operational safety is directly related to the mine's production efficiency and personnel safety. The gangue protection device, as an important safety accessory of the scraper conveyor, is mainly used to block the splashing or rolling gangue during transportation, so as to prevent the gangue from damaging core components such as cable troughs and hydraulic pipelines, and at the same time prevent the gangue from endangering the safety of workers.

[0003] Currently, most mining scraper conveyor rock-blocking protection devices on the market adopt a fixed structure or a simple manual adjustment design. The adjustableness of the protection area of ​​the baffle is poor, especially the height of the lower half of the baffle, which cannot be flexibly adjusted. Specifically, the height of many baffles is fixed after installation and cannot be changed according to the actual working conditions. Some baffles with adjustment functions can only achieve minor adjustments to the angle of the upper half, while the height of the lower half remains unchanged. However, the underground working environment in coal mines is complex and variable. Because the existing baffles cannot be adjusted in height, the devices are difficult to adapt to diverse usage environments, and the protection range is limited. Rock can still bypass the baffle, causing equipment damage or personnel injury, and the protective effect and usage efficiency are greatly reduced.

[0004] Therefore, a new type of rock-blocking protection device for mining scraper conveyors is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the problems raised in the background art by proposing a new type of mine scraper conveyor rock-blocking protection device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A novel protective device for preventing rock spillage on a mining scraper conveyor includes a cable trough fixedly installed on the conveyor. A first baffle is vertically inserted into the inside of the cable trough. An elastic mechanism is provided between the bottom of the first baffle and the bottom of the cable trough, and a second baffle is slidably installed on the top of the first baffle.

[0008] A mounting base is fixedly provided on one side of the cable trough, and a hydraulic cylinder is fixedly provided on the mounting base. A connecting block is fixedly provided on the side of the second baffle, and the connecting block is fixedly connected to the moving end of the hydraulic cylinder.

[0009] Two pulling blocks are symmetrically fixed on the top side of the second baffle, and the two pulling blocks correspond to the top position of the first baffle.

[0010] Preferably, the elastic mechanism includes a fixed plate fixedly disposed at the bottom of the first baffle, and telescopic rods are fixedly disposed on both sides of the upper surface of the fixed plate. The upper ends of the two telescopic rods are fixedly connected to the bottom of the cable trough. Springs are sleeved on the rod walls of the two telescopic rods, and the two ends of the springs are fixedly connected to the upper surface of the fixed plate and the bottom of the cable trough, respectively.

[0011] Preferably, both sides of the second baffle are fixedly provided with snap-fit ​​sliders, and both sides of the first baffle are provided with snap-fit ​​grooves that cooperate with the snap-fit ​​sliders.

[0012] Preferably, the top of the cable trough has two symmetrical mounting holes, and the interior of the mounting holes is used to insert bolts for connection with the conveyor.

[0013] Preferably, the sides of the first baffle and the sides of the second baffle are provided with a wear-resistant coating.

[0014] Preferably, both the first baffle and the second baffle are made of stainless steel, and the height of the second baffle is less than the height of the first baffle.

[0015] Compared with the prior art, this utility model provides a novel protective device for preventing rock spillage on a mining scraper conveyor, which has the following beneficial effects:

[0016] 1. This new type of mine scraper conveyor rock-blocking protection device uses a hydraulic cylinder to drive the second baffle to slide up and down. When the second baffle moves down, the pulling block drives the first baffle to move downward against the elastic force of the telescopic rod and spring, realizing bidirectional adjustment of the overall protection area of ​​the first and second baffles in the vertical direction. When the second baffle is pushed upward, the spring applies elastic force to the fixed plate, so that the first baffle can automatically move upward on the cable trough.

[0017] 2. This new type of mine scraper conveyor rock-blocking protection device enhances the wear resistance of the baffles and extends the service life of the device by setting wear-resistant coatings on the sides of the first and second baffles, and both the first and second baffles are made of stainless steel.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Reference Figure 1-4A novel protective device for preventing rock spillage on a mining scraper conveyor includes a cable trough 1 fixedly mounted on the conveyor. Two mounting holes 13 are symmetrically opened at the top of the cable trough 1, and bolts for connecting to the conveyor are inserted into the mounting holes 13. A first baffle 2 is vertically inserted into the inside of the cable trough 1, and an elastic mechanism is provided between the bottom of the first baffle 2 and the bottom of the cable trough 1. A second baffle 3 is slidably mounted on the top of the first baffle 2. Locking sliders 11 are fixedly mounted on both sides of the second baffle 3. Locking grooves 12 that cooperate with the locking sliders 11 are opened on both sides of the first baffle 2. The cooperation between the locking sliders 11 and the locking grooves 12 increases the sliding stability between the first baffle 2 and the second baffle 3, and prevents the first baffle 2 and the second baffle 3 from separating. A wear-resistant coating 14 is provided on the sides of both the first baffle 2 and the second baffle 3. This design increases the wear resistance of the surfaces of the first baffle 2 and the second baffle 3, improving their service life. Both the first baffle 2 and the second baffle 3 are made of stainless steel, and the height of the second baffle 3 is less than that of the first baffle 2. A mounting base 4 is fixedly installed on one side of the cable trough 1, and a hydraulic cylinder 5 is fixedly installed on the mounting base 4. A connecting block 6 is fixedly installed on the side of the second baffle 3, and the connecting block 6 is fixedly connected to the moving end of the hydraulic cylinder 5. Two pulling blocks 7 are symmetrically fixedly installed on the top side of the second baffle 3, and the two pulling blocks 7 correspond to the top position of the first baffle 2. When the second baffle 3 moves down a certain distance, the two pulling blocks 7 push the first baffle 2 down to move, making the height of the first baffle 2 adjustable. Conversely, when the second baffle 3 moves up, the elastic mechanism applies an upward elastic force to the first baffle 2, causing the first baffle 2 to move up automatically.

[0026] The elastic mechanism includes a fixed plate 8 fixedly installed at the bottom of the first baffle 2. Telescopic rods 9 are fixedly installed on both sides of the upper surface of the fixed plate 8. The upper ends of the two telescopic rods 9 are fixedly connected to the bottom of the cable trough 1. Springs 10 are sleeved on the rod walls of the two telescopic rods 9. The two ends of the springs 10 are fixedly connected to the upper surface of the fixed plate 8 and the bottom of the cable trough 1, respectively. When the second baffle 3 moves upward, the springs 10 apply an upward elastic force to the fixed plate 8, so that the second baffle 3 can move upward automatically.

[0027] In this utility model, the cable trough 1 is fixed to the conveyor with bolts through the symmetrically opened mounting holes 13 on the top of the cable trough 1. During operation, the hydraulic cylinder 5 is fixed on the mounting seat 4 on one side of the cable trough 1. When the hydraulic cylinder 5 drives the second baffle 3 to move upward, the protection height increases. When the second baffle 3 moves downward, the pulling block 7 on the top of its side contacts the top of the first baffle 2, causing the first baffle 2 to move downward against the elastic force of the telescopic rod 9 and the spring 10. This achieves bidirectional adjustment of the overall protection area of ​​the first baffle 2 and the second baffle 3 in the vertical direction. Both the first baffle 2 and the second baffle 3 are adjustable, which solves the problems of poor adjustability of the protection area of ​​the existing baffle and the inability to adjust the height of the lower half. It can adapt to different working conditions in coal mines.

[0028] When the gangue impacts the first baffle 2 and the second baffle 3, both the first baffle 2 and the second baffle 3 are made of stainless steel and have a wear-resistant coating 14 on the side, which can enhance the wear resistance.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
