Description

Technical Field

[0001] The utility model relates to the technical field of mining machinery and equipment, in particular to a stepping type self-moving tail for a belt conveyor. Background Art

[0002] The walking self-moving tail of the belt conveyor is a commonly used mechanical equipment in mines. The main function of the walking self-moving tail of the belt conveyor is to move forward with the advancement of the excavation equipment while the excavation face is working normally, so as to realize the automatic movement of the tail. Due to geological conditions, the existing walking self-moving tail of the belt conveyor usually adopts the extension of the tail frame to provide a moving track and a buffer for the coal drop point for the transfer equipment; after completing the coal mining operation in an area, it is necessary to stop production for maintenance. During this period, the overall length of the walking self-moving tail of the belt conveyor is adjusted to the shortest, and then extended with the advancement of the excavation equipment.

[0003] When the existing belt conveyor uses a walking self-moving tail to extend or shorten the overall length, the tail is pulled by a wire rope with the help of a traction device, which easily causes the tail to be pulled off-center, thereby causing the belt set on the tail to deviate and need to be adjusted in time. The adjustment is difficult, time-consuming and labor-intensive; therefore, it is necessary to propose a device that facilitates the deviation correction of the tail belt. Utility Model Content

[0034] Specifically, in this embodiment, a driven roller 110 and a driving roller are respectively provided at both ends of the self-moving tail body, wherein a conveyor belt 120 is sleeved on the driven roller 110 and the driving roller, and the driving roller is connected to the rotary drive motor of the self-moving tail body by transmission, and the rotary drive motor can control the rotation of the driving roller, thereby driving the driven roller 110 to rotate through the conveyor belt 120. In this embodiment, a tensioning device is provided on the self-moving tail body, and the conveyor belt 120 can be retracted and released through the tensioning device during the overall extension or shortening of the self-moving tail body. A tail roller seat 100 is provided at one end of the self-moving tail body, and the driven roller 110 is installed on the tail roller seat 100.

The driven roller 110 can be installed on the tail roller seat 100 and the roller seat 111 by installing bearing seats at both ends thereof, and the position of the bearing seats can be controlled by the correction device 200, thereby changing the position of the axis of the driven roller 110 and correcting the conveyor belt 120.

[0036] In this embodiment, the deviation correction device 200 includes an adjustment seat 210, an adjustment screw 220 and a pre-tightening assembly 230, wherein the adjustment seat 210 is installed on the tail roller seat 100 along the length direction of the tail roller seat 100, and the driven roller shaft 110 is connected to the adjustment seat 210. In this embodiment, when the external rotation installation method is adopted, the adjustment seat 210 is fixedly connected to the bearing seat; the pre-tightening assembly 230 is fixedly connected to the tail roller seat 100 and abuts against the adjustment seat 210 through the push rod 231, providing a pre-tightening force to prevent the adjustment seat 210 from sliding after being adjusted to the specified position. When the conveyor belt 120 deviates, the adjustment seat 210 is controlled to slide on the tail roller seat 100 by rotating the adjustment screw 220, thereby changing the axial position of the driven roller shaft 110, and then correcting the conveyor belt 120.

[0037] In some embodiments of the utility model, the preload assembly 230 includes a sleeve 232 and a preload spring 233; an elastic chamber 234 is provided in the sleeve 232, and one end of the sleeve 232 is open; the push rod 231 is slidably installed in the elastic chamber 234, and the preload spring 233 is provided in the elastic chamber 234, and one end of the preload spring 233 abuts against the sleeve 232, and the other end abuts against the push rod 231.

[0038] In some embodiments of the utility model, hydraulic oil is provided in the elastic chamber 234. In this embodiment, since the deviation correction device 200 is in an idle state most of the time, by providing hydraulic oil in the elastic chamber 234, lubrication can be provided to maintain the smoothness of the sliding of the push rod 231. In addition, the hydraulic pressure also has a limiting effect. When the push rod 231 slides to a certain state, the hydraulic oil is compressed to a limit state in the elastic chamber, preventing the preload spring 233 from being further compressed, thereby protecting the preload spring 233 and preventing the preload spring 233 from plastic deformation and failure.

In this embodiment, the deviation correction device 200 includes an adjustment seat 210, an adjustment screw 220, a deviation correction motor 240, a reducer 250, a first gear 260 and a second gear 270. Specifically, the correction motor 240 outputs driving force through the reducer 250. By setting the reducer 250, the rotation speed can be proportionally reduced to improve the control accuracy. The reducer 250 can transmit the power to the adjusting screw 220 through the first gear 260 and the second gear 270. Further, by controlling the rotation of the adjusting screw 220, the adjusting seat 210 is controlled to slide on the tail roller seat 100.

In this embodiment, by setting the first gear 260 and the second gear 270 as bevel gears, the transmission direction of the driving force can be changed, so that the reaction force received by the adjustment seat 210 can be prevented from directly acting on the deviation correction motor 240 or the reducer 250, resulting in overload damage. Through the design of this mechanism, the service life of the deviation correction motor 240 and the reducer 250 can be increased.

[0041] In some embodiments of the utility model, the bottom of the tail roller seat 100 is provided with a first wedge 130, a second wedge 140 and a hydraulic cylinder 150; the first wedge 130 is fixedly connected to the tail roller seat 100, and the first wedge 130 is slidably arranged on the self-moving tail body; the first wedge 130 is provided with a first inclined surface, and the second wedge 140 is provided with a second inclined surface corresponding to the first inclined surface, and the first inclined surface is in contact with the second inclined surface; the hydraulic cylinder 150 is fixedly connected to the self-moving tail body, and the output end of the hydraulic cylinder 150 is hinged to the second wedge 140.
