Technical Field
[0001] This invention belongs to the field of mining equipment technology, specifically relating to a telescopic structure at the loading end of a conveyor belt soil dumping machine's transfer trolley. Background Technology
[0002] Open-pit mines use a combination of belt conveyors and belt dumpers for soil removal (such as...). Figures 1-3 As shown, the device includes a belt conveyor 1, on which a belt take-up and untake-down device 12 is installed; a transfer trolley 11 is installed on the belt conveyor 1, and the belt extends from the belt conveyor 1, wraps around the frame on the transfer trolley 11, and is cyclically connected to the belt conveyor 1; waste rock is transported from the belt conveyor 1 to the receiving arm 21 of the excavator through the conveying end of the transfer trolley 11, and discharged through the discharge arm 22 of the excavator; the receiving arm 21 and the discharge arm 22 of the excavator are installed on the excavator 2; the belt between the belt conveyor and the loading end of the transfer trolley is suspended to facilitate the movement of the transfer trolley; this device has low energy consumption, low transportation cost, and high degree of automation.
[0003] However, most existing belt conveyor soil dumping machines have a loading end frame (the part that connects to the belt conveyor, such as...) Figure 3 The length of the conveyor belt (as shown) is insufficient, resulting in a long suspended section of the belt between the conveyor and the loading end of the transfer trolley. This increases the tension on the belt, making it prone to breakage, accelerating belt wear, increasing transportation and maintenance costs in the mine, and potentially causing transportation accidents or even safety incidents. Simply extending the lower end of the frame at the loading end of the transfer trolley would cause interference between the lower end of the loading end and the conveyor frame during trolley movement, making movement difficult. Therefore, researching a retractable structure for the loading end of the transfer trolley in a conveyor belt soil dumping machine is a pressing practical need. Summary of the Invention
[0004] To solve the above-mentioned technical problems, the present invention provides a telescopic structure for the loading end of the transfer trolley of a conveyor belt soil discharge machine, which can realize the extension and retraction of the loading end of the transfer trolley of the conveyor belt soil discharge machine, which can provide good support for the conveyor belt, and at the same time avoid interference between the transfer trolley and the conveyor belt conveyor when the transfer trolley moves.
[0005] The specific technical scheme is as follows: a telescopic structure of a loading end of a transfer trolley of a belt reclaimer, a transfer trolley is arranged on a belt conveyor, a belt is extended from the belt conveyor and is arranged in a loop around a rack of the transfer trolley, and the belt is connected with the belt conveyor in a circulation mode; the lower end of the transfer trolley is connected with the belt conveyor at the loading end of the transfer trolley, and the upper end of the transfer trolley is connected with a receiving arm of the reclaimer; the receiving arm of the reclaimer and a discharging arm of the reclaimer are arranged on the reclaimer, and the discharging arm of the reclaimer is arranged to discharge; a telescopic structure is arranged on the rack at the lower end of the loading end of the transfer trolley, the telescopic structure comprises a pair of telescopic beams, and the telescopic beams are in a rectangular shape; the longitudinal beams between two upper supporting rollers adjacent to the rack ports at the lower end of the rack of the loading end of the transfer trolley are the telescopic beams, and the outer sleeve end of the telescopic beam and the inner sleeve of the telescopic beam are respectively provided with locking bolts; a rotating rod is rotatably arranged in the inner sleeve of each telescopic beam, and the lower end of the rotating rod is rotatably provided with a movable supporting roller; and the telescopic structure further comprises a pair of telescopic rods, one end of each telescopic rod is rotatably connected with the longitudinal beam at the end of the telescopic part of the telescopic beam, and the other end of each telescopic rod is rotatably connected with the rotating shaft of the movable supporting roller.
[0006] Further, the telescopic beam is at least two telescopic beams, that is, at least comprises an outer sleeve and an inner sleeve, and the inner sleeve is arranged in the outer sleeve, and a sliding rod is arranged in the inner sleeve.
[0007] Further, the distance between the connection position of the upper end of the rotating rod and the telescopic beam and the connection position of the upper end of the telescopic rod and the sliding rod is not less than the length of the rotating rod, so that the movable supporting roller can be lifted to the position where the two upper supporting rollers are flush when the telescopic beam is elongated. Beneficial effects
[0008] When the belt reclaimer discharges (the transfer trolley and the belt conveyor are stationary), the telescopic structure is stretched, so that the movable supporting roller rolls and supports the belt at the loading end of the transfer trolley; when the transfer trolley moves on the belt conveyor, the telescopic structure is retracted, so that the telescopic structure does not interfere with the belt conveyor.
[0009] The present application can elongate the rack of the loading end of the transfer trolley of the belt reclaimer, and can automatically provide a supporting roller after the rack of the loading end is elongated, so that the belt is not suspended for too long, the belt is uniformly stressed, the service life and the transportation safety and stability of the belt are improved, the transportation and maintenance costs of the mine are reduced, the transportation safety and production stability of the mine are ensured, the superiority of the continuous transportation of the belt reclaimer is fully utilized, and certain economic benefits are provided for the mine. Meanwhile, the telescoping of the loading end of the transfer trolley avoids interference between the transfer trolley and the belt conveyor when the transfer trolley moves.
[0010] (1) The telescopic structure is added to the original rack of the loading end of the transfer trolley, the rack of the loading end of the transfer trolley can be elongated, the length of the rack of the loading end of the transfer trolley can be flexibly adjusted according to needs, the belt conveyor is conveniently connected, the working range of the belt conveyor is increased, the process flexibility is improved, and the practicality is high.

[0021] Further, the telescopic beam 3 is at least two telescopic beams, that is, at least comprises an outer sleeve and an inner sleeve, the inner sleeve is arranged in the outer sleeve, and a slide rod 10 is arranged in the inner sleeve.
[0022] Further, the distance between the connection position of the upper end of the rotating rod 5 with the telescopic beam 3 and the connection position of the upper end of the telescopic rod 8 with the slide rod 10 is not less than the length of the rotating rod 5, so as to ensure that the movable idler 7 can be lifted to the position where the two upper idlers 6 are flush when the telescopic beam 3 is elongated. Embodiment
[0023] The transfer car loading end telescopic structure mainly comprises a telescopic beam 3, a locking bolt 4, a rotating rod 5, an upper idler 6, a movable idler 7 and a telescopic rod 8 (as shown in Figures 4-6 ).
[0024] (1) The upper idler 6 carries the belt and is installed on the telescopic beam 3, and the movable idler 7 is installed on the rotating rod 5 and is hinged with the rotating rod 5. The upper idler 6 is a fixed idler, and when the receiving arm is completely retracted, the distance between the two upper idlers 6 is L (as shown in Figure 4 ).
[0025] (2) The telescopic beam 3 is two sections of telescopic beams and is located between the two upper idlers 6, and is used for adjusting the length of the transfer car loading end frame. Each telescopic beam end of the telescopic beam 3 is provided with a locking bolt 4, which is used for fixing the length after telescoping (as shown in Figures 4-6 ).
[0026] (3) The rotating rod 5 is located at the innermost side of the telescopic beam 3, one end of which is hinged to the telescopic beam 3, and the other end is hinged to the movable carrier roller 7 and the telescopic rod 8. The length of the rotating rod 5 is S (the effective length of the rotating rod 5, that is, the distance between the center of the upper end of the rotating rod 5 connected to the telescopic beam 3 and the center of the lower end of the rotating rod 5 connected to the telescopic rod 8), and when the telescopic beam 3 is fully retracted, the hinged part of the rotating rod 5 and the telescopic beam 3 is also S away from the center of the upper carrier roller 6 (as shown in Figure 3 ). The rotating rod 5 can rotate around the hinged part thereof and the telescopic beam 3, thereby adjusting the height of the movable carrier roller 7 (as shown in Figures 4-6 ).
[0027] (4) The telescopic rod 8 is two sections of telescopic, one end of which is hinged to the telescopic beam 3, and the other end is hinged to the rotating rod 5. The telescopic rod 8 telescopes with the telescopic beam 3, and simultaneously drives the rotating rod 5 to rotate, when the telescopic rod 8 is fully extended, the rotating rod 5 rotates to be parallel to the telescopic beam 3, and at the same time, the movable carrier roller 7 also rises to be parallel to the two upper carrier rollers 6. At this time, the distance between the movable carrier roller 7 and the front and rear upper carrier rollers 6 is L, which is the same as the distance between the two upper carrier rollers 6 when the telescopic beam 3 is fully retracted (as shown in Figures 4-6 ).
[0028] In specific use, the telescopic beam 3 is extended, driving the telescopic rod 8 to extend, and then driving the rotating rod 5 to rotate, and then driving the movable carrier roller 7 to rise. When the telescopic rod 8 is fully extended, the locking bolt 4 is rotated to fix the length of the telescopic beam 3. At this time, the rotating rod 5 rotates to be parallel to the telescopic beam 3, and at the same time, the movable carrier roller 7 also rises to be parallel to the two upper carrier rollers 6, so that the movable carrier roller 7 rolls and supports the rubber belt on the loading end of the transfer trolley; and the distance between the movable carrier roller 7 and the front and rear upper carrier rollers 6 is L, which is the same as the distance between the two upper carrier rollers 6 when the telescopic beam 3 is fully retracted (as shown in Figure 5 ). When the transfer trolley moves on the rubber belt conveyor (the transfer trolley and the reclaimer are moved), the telescopic structure is retracted to avoid interference between the telescopic structure and the rubber belt conveyor.
