Description

Technical Field

[0001] The utility model relates to the technical field of travel control devices, in particular to a travel control device for a slag discharger. Background Art

[0002] The slag discharger stroke control device (also called the waste slag treatment machine stroke control device) is a device used to control the working process of the slag discharger. It is mainly used in the waste slag treatment industry to control the movement, lifting, steering and other operations of the slag discharger.

[0003] When the existing slag discharger is in use, the coal slag is transported by a conveyor belt. Since the working sites of the slag discharger are of different sizes, the stroke length of the conveyor belt needs to be adjusted according to the use environment. If the stroke of the conveyor belt of the slag discharger cannot be adjusted, then in different working scenarios, the stroke length cannot be adjusted according to actual needs, which will limit the flexibility and applicability of the slag discharger.

[0025] Manually turn the knob 4 to drive the bidirectional screw rod 13 to rotate, and the bidirectional screw rod 13 drives the two slides 10 to move closer to each other or away from each other. The slide 10 drives the driving arm 11 to move, and the driving arm 11 drives the telescopic plate 8 to extend or retract through the fixed seat 12. Since the two moving rollers 6 are rotatably installed between the telescopic plates 8, the moving rollers 6 will move synchronously with the telescopic plates 8, and the moving rollers 6 will adjust the extension length of the conveyor belt 7 when they move. Through this device, the stroke length of the conveyor belt 7 can be flexibly adjusted according to the requirements of the use environment, which greatly improves the flexibility and applicability of the device.

[0026] In this embodiment, a driving motor 3 is fixedly installed on the outer surface of the base 1 near the knob 4. The output end of the driving motor 3 passes through the outer surface of the base 1 and is fixedly installed with the rotation center of one of the fixed rollers 5. The driving motor 3 drives one of the fixed rollers 5 to rotate, so that the fixed roller 5 drives the conveyor belt 7 to move, thereby facilitating the transportation of the coal slag on its upper surface.

[0027] In this embodiment, self-locking universal wheels 2 are fixedly installed at the four corners of the lower surface of the base 1, and the user moves the device to a specified position through the self-locking universal wheels 2.

[0028] In this embodiment, the planes of the conveyor belt 7 are arranged parallel to each other, and the diameters of the movable roller 6 and the fixed roller 5 are the same. By arranging the surfaces of the conveyor belt 7 in parallel and arranging the diameters of the movable roller 6 and the fixed roller 5 to be the same, it is convenient to correctly adjust the transport stroke length of the conveyor belt 7.

[0029] It should be noted that when the utility model is in use, the user moves the device to the specified position through the self-locking universal wheel 2, and then manually turns the knob 4 according to the requirements of the use environment, so that the knob 4 drives the bidirectional screw 13 to rotate, and the two slides 10 are driven to move closer to each other or away from each other through the bidirectional screw 13, and the slide 10 drives the driving arm 11 to move, so that the driving arm 11 drives the telescopic plate 8 to extend or retract through the fixed seat 12. Since the two moving rollers 6 are rotatably installed between the telescopic plates 8, the moving rollers 6 will move synchronously with the telescopic plates 8, and the moving rollers 6 will adjust the extension length of the conveyor belt 7 when they move. Through this device, the stroke length of the conveyor belt 7 can be flexibly adjusted according to the requirements of the use environment, which greatly improves the flexibility and applicability of the device; one of the fixed rollers 5 is driven to rotate by the driving motor 3, so that the fixed roller 5 drives the conveyor belt 7 to move, which is convenient for conveying the coal slag on its upper surface.
