Description

Technical Field

[0001] The utility model relates to the technical field of scraper conveyors, in particular to an electric braking device of a scraper conveyor. Background Art

[0002] A scraper conveyor is a conveyor that uses a scraper chain to transport bulk materials in a trough. A scraper conveyor is one of the important transportation equipment in mines. It can be used to transport coal, gangue or materials from low to high. In actual use, when an emergency occurs, the position of the scraper conveyor needs to be limited by an electric hydraulic brake device so that it cannot be easily rotated to affect its use.

[0003] However, there are many types of electric hydraulic brake devices in the prior art, and the size of the brake clearance of the conventional brake is mainly adjusted by means of a top screw, which is complicated to operate. By adjusting the clearance adjustment bolt on the left or right side, the distance between the brake pad and the brake wheel when the brake is opened is adjusted, which is relatively cumbersome.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] In the description of the present invention, it should be noted that the terms "vertical", "up", "down", "horizontal", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0018] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] See also Figure 1 The utility model provides a technical solution: an electric braking device for a scraper conveyor, comprising a scraper conveyor 1 and a braking mechanism, wherein a driving motor 2 is fixedly connected to one side of one end of the scraper conveyor 1, and an output end of the driving motor 2 is connected to a rotating shaft of the scraper conveyor 1, and a braking mechanism 3 is arranged on the other side of one end of the scraper conveyor 1.

[0020] It should be noted that the scraper conveyor 1 is an existing mature technology, and its specific internal structure and working principle will not be described in detail here. The scraper conveyor 1 is moved by the driving motor 2. When it is necessary to limit the position of the scraper conveyor 1 due to an emergency, it cannot be easily rotated to affect its use.

[0021] See also Figure 2 The braking mechanism 3 includes a fixed disk 301, a first sliding block 303, and a brake pad 309. The other end of the rotating shaft of the scraper conveyor 1 extends out of the scraper conveyor 1. The rotating shaft of the scraper conveyor 1 is fixedly sleeved with a fixed disk 301, and the first sliding block 303 is arranged at the bottom of the other side of the scraper conveyor 1.

[0022] Furthermore, a slide groove 305 is provided on the top of the first sliding block 303, and the centers of the two ends of the slide groove 305 are respectively connected to the two ends of the bidirectional threaded rod 306, and a second sliding block 307 is sleeved on the surface of the bidirectional threaded rod 306, and the second sliding block 307 is slidably connected to the slide groove 305.

[0023] Furthermore, a rotating motor 304 is fixedly connected to one side of the first sliding block 303 , and an output end of the rotating motor 304 is connected to one end of the bidirectional threaded rod 306 .

[0024] When used for the first time, the distance between the two second sliding blocks 307 needs to be adjusted. Specifically, when in use, the rotation motor 304 is started through the controller. The rotation of the rotation motor 304 will cause the bidirectional threaded rod 306 to rotate. The rotation of the bidirectional threaded rod 306 will cause the two second sliding blocks 307 to move towards the middle, or the two second sliding blocks 307 can also move towards both sides, which is mainly determined by the rotation direction of the rotation motor 304. Among them, by knowing how many turns the rotation motor 304 rotates, the moving distance of the second sliding block 307 can be understood, and the operation is relatively simple. When the inner surface of the brake pad 309 is connected to the surface of the rotating shaft of the scraper conveyor 1, the positions of the two brake pads 309 will be positioned.

[0025] Furthermore, an installation frame 312 is provided at the front end of the top of the first sliding block 303. The installation frame 312 is in a "C" - shaped structure with the opening facing backward. The top and bottom of the front of the opening surface of the installation frame 312 are connected to the fixed ends of the electric cylinders 308. The telescopic ends of the electric cylinders 308 are connected to the top and bottom of the front of the connecting plate 311. A brake pad 309 is provided on the back of the connecting plate 311. The inner surface of the brake pad 309 is in contact with the rotating shaft of the scraper conveyor 1. A fixing rod 310 is provided at the bottom of the back of the connecting plate 311. A number of fixing openings 302 are provided on the front and back outer edges of the fixing plate 301, and the fixing openings 302 are snap - connected to the fixing rod 310.

[0026] Specifically, when in use, the rotation motor 304 and the electric cylinders 308 are started through the controller. The start of the electric cylinders 308 will cause the connecting plate 311 to move backward. The movement of the connecting plate 311 will cause the brake pad 309 to move backward, so that the back of the brake pad 309 is in contact with the front of the fixing plate 301. At the same time, the rotation of the rotation motor 304 will cause the second sliding block 307 to move towards the middle, thereby emergently braking the rotating shaft through the brake pad 309.

[0027] At the same time, after the movement of the connecting plate 311, the fixing rod 310 will move forward. During the movement, the fixing rod 310 can be inserted into one of the fixing openings 302 to further emergently brake the rotating shaft.

[0028] It should be noted that the brake pad 309 is an existing mature technology, and its specific internal structure and working principle will not be described in detail here.

[0029] A buffer sheet is provided on the inner surface of the brake pad 309, so it can be applied to brake rotating shafts with different diameters.

[0030] It is worth noting that the entire device is controlled through the controller. Since the controller is a common device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be elaborated here.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
