Description

Technical Field

[0001] The utility model belongs to the technical field of coal storage bunker ash cleaning, and particularly relates to a trailing trolley for a stacker-reclaimer. Background Technique

[0002] In the ground coal conveying system, the 50,000-ton coal storage bunker serves as a belt transportation transfer and storage site, and its structural design is a hemispherical shape composed of a framework and color steel. The inside of the coal storage bunker is equipped with a top-stacking side-taking stacker-reclaimer, which is specially designed for the storage and outward transportation tasks of coal in the coal storage bunker. The stacker-reclaimer adopts a rotary power supply method of a high-voltage slip ring and carbon brushes, that is, it is connected to the carbon brushes through a high-voltage cable inside the central column and then transmitted to the wiring busbar of the high-voltage incoming line cabinet in the power distribution room. The whole equipment consists of a stacking belt conveyor and a reclaiming scraper mechanism, and can realize 360° stacking and reclaiming operations of coal in the bunker.

[0003] Since the power supply control system of the stacker-reclaimer is located on the second-floor platform of the whole machine, and the stacking belt conveyor is located at the top layer of the equipment. In order to supply power and control the stacking belt conveyor, it is necessary to use a low-voltage control cable from the second-floor low-voltage power distribution room to the top-layer stacking belt conveyor, and use the traction of the trailing trolley to rotate around the outer periphery of the central column, so as to avoid the intertwining of cables during the rotation process and thus hinder the power supply of the stacker-reclaimer.

[0004] However, as a closed and airtight space, it is difficult for coal dust to diffuse in the coal storage bunker, which causes the slideway of the trailing trolley to be easily dust-accumulated, thus affecting the normal operation of the trailing trolley. At present, solving the problem of dust accumulation on the slideway mainly relies on the daily cleaning work of cleaning personnel, and tools are used to manually remove the dust on the slideway. However, this method has low efficiency and potential safety hazards. Especially when the equipment is running continuously, it is difficult to carry out the cleaning work in time, which may lead to more serious dust accumulation problems, increase the risk of failure of the rotary motor frequency converter of the stacker-reclaimer, shorten the service life of the equipment, and affect the production efficiency. In addition, the cleaning personnel are at risk of electric shock when cleaning close to the cables. Summary of the Utility Model

[0005] In order to solve the problem that in the background technique, as a closed and airtight space, it is difficult for coal dust to diffuse in the coal storage bunker, which causes the slideway of the trailing trolley to be easily dust-accumulated, thus affecting the normal operation of the trailing trolley, the following technical solutions are proposed in the utility model:

[0006] A trailing trolley for a stacker-reclaimer, which is arranged on a track on the outer periphery of the central column of the stacker-reclaimer, includes: a guiding wheel set, a clamping seat, a stabilizing frame, an ash removal hopper and a driving motor; the guiding wheel set clamps the track to support the clamping seat to be suspended on the track, and the guiding wheel set is rotatably arranged on the stabilizing frame; a back plate for fixing the stabilizing frame is formed by a protrusion on the surface of the clamping seat, and the surface of the clamping seat bears and limits the power supply cable; the stabilizing frame is fixedly arranged on both sides of the back plate; the fixed end of the ash removal hopper is fixedly arranged on the stabilizing frame, and the free end of the ash removal hopper abuts against the surface of the track; the driving motor meshes with the guiding wheel set; during the operation of the stacker-reclaimer, the driving motor drives the ash removal hopper through the guiding wheel set to process the ash accumulated on the surface of the track.

It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0016] It should be understood that the orientation or positional relationships indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings. These are only for the convenience of describing this patent and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of this patent.

[0017] Figure 1 Schematic structural diagram of a trailing trolley for a stacker-reclaimer according to an embodiment of the present utility model. For a clearer display of the structure of this application, the track is omitted.

[0018] Refer to Figure 1 , a trailing trolley for a stacker-reclaimer according to an embodiment of the present utility model includes: a guiding wheel set 1, a clamping seat 2, a stabilizing frame 3, an ash removal hopper 4, and a driving motor 5. Among them, the guiding wheel set 1 clamps the track on the outer periphery of the central column of the stacker-reclaimer, so as to support the clamping seat 2 to be suspended on the track. A back plate 7 is formed by the surface protrusion of the clamping seat 2 for fixing the stabilizing frame 3. A limiting cavity for clamping the cable of the stacker-reclaimer is provided inside the clamping seat 2. The stabilizing frame 3 is fixed on both sides of the back plate 7, providing a stable support structure for the installation of the guiding wheel set 1. The fixed end of the ash removal hopper 4 is fixed on the stabilizing frame 3, and the free end of the ash removal hopper 4 abuts against the track surface. The driving motor 5 meshes with the guiding wheel set 1. During the operation of the stacker-reclaimer, the driving motor 5 drives the guiding wheel set 1 to rotate, so that the ash removal hopper 4 removes the coal ash on the track under the action of inertia.

[0019] Continue to refer to Figure 1, specifically, the clamping seat 2 includes an upper part 21 and a lower part 22. Among them, the upper part 21 is in a bridge shape, and the lower parts 22 are all in an arc shape. The upper part 21 is erected on the surface of the lower part 22 along the axial direction of the lower part 22, and the upper part 21 and the lower part 22 are detachably connected together by a long-axis connecting piece such as a bolt. A vertical protrusion is formed on the surface of the upper part 21 away from the lower part 22, thereby forming a back plate 7.

[0020] Under the action of multiple trailing trolleys, the cable sequentially passes through the limiting cavities in the clamping seats 2 of each trailing trolley, thereby ensuring that the cable and the stacker-reclaimer always remain relatively stationary during the operation of the stacker-reclaimer. Preferably, in this embodiment, in order to further improve the dust removal effect, the trailing trolley of this embodiment further includes a blower 8 fixedly arranged on the surface of the upper part 21 away from the lower part 22. During the operation of the stacker-reclaimer, the blower 8 continuously operates, thereby blowing dust on the track in the advancing direction of the trailing trolley, thereby improving the dust cleaning effect of the entire trailing trolley.

[0021] Furthermore, the stabilizing frame 3 includes a plurality of vertical parts 31 and a plurality of horizontal parts 32. Each vertical part 31 is fixedly arranged on one of the two wide faces of the back plate 7, and each pair of vertical parts 31 is fixedly connected to a horizontal part 32. Both ends of each horizontal part 32 are respectively located above the wide faces of the back plate 7. After the horizontal part 32 is fixedly connected to the back plate 7, the horizontal part 32 fixes the two vertical parts 31 to the back plate 7 at the same time.

[0022] Figure 2 It is a schematic side view of a trailing trolley for a stacker-reclaimer according to an embodiment of the present invention.

[0023] Refer to Figure 2 , the track clamping the outer periphery of the central column of the stacker-reclaimer is an I-beam. Part of the end faces of the guide wheel sets 2 jointly clamp the vertical part of the track, and part of the outer periphery of the guide wheel sets 2 abuts against the horizontal part of the track.

[0024] Refer to Figure 2 , specifically, the guide wheel set 1 includes a first runner 11 and a second runner 12. Among them, the rotation directions of the first runner 11 and the second runner 12 are perpendicular to each other, and the axes of the first runner 11 and the second runner 12 are perpendicular to each other. The rotating shaft of the first runner 11 is arranged on the vertical part 31, and the rotating shaft of the second runner 12 is arranged on the horizontal part 32. The first runner 11 is a driving wheel, and it is meshed and connected with the driving motor 5 through a transmission member (such as a gear, etc.). During the operation of the stacker-reclaimer, the driving motor 5 drives the first runner 11 to move along the track through the transmission member (at this time, the outer peripheral surface of the first runner 11 abuts against the surface of the track). The second runner 12 is a driven wheel, and its outer peripheral surface abuts against the side wall of the track, thereby reducing the friction between the entire trailing trolley and the track during the movement.

[0025] In summary, the utility model stabilizes the cables of the stacker-reclaimer by designing a drag chain trolley clamping seat, and a corresponding ash removal hopper is arranged at the forward end of the drag chain trolley, so that the track can be cleaned while keeping the cables relatively stationary with respect to the stacker-reclaimer during the movement of the drag chain trolley.
