Description

Technical Field

[0001] The utility model relates to an iron suction device for cleaning iron debris on a belt conveyor in a mine. Background Art

[0002] In the process of gold ore mining, due to its unique mining method, that is, searching for gold veins through tunnel excavation, it is significantly different from the large-scale comprehensive mining of coal mines and iron mines. This method often causes a large amount of metal waste such as anchor rods and anchor nets in the ore brought up from the well. If these metal debris are not removed in time, they will cause serious damage to equipment such as belt conveyors, affecting the continuity and safety of production.

[0003] In order to remove these metal debris, the existing technology mainly relies on a suction cup type magnetic device. The magnetic device works by reciprocating horizontal magnetic suction. After reaching the top of the belt conveyor, it will be electromagnetically sucked, suck up the debris and then move horizontally to the top of the recycling box. After the power is turned off and the debris is put down, it returns to the top of the belt conveyor to start the next round of magnetic suction, and so on.

[0004] However, the existing magnetic magnet has the following problems:

[0005] 1. The magnetic device cannot achieve the same speed of adsorption as the conveyor belt, and the conveyor belt needs to be stopped intermittently to cooperate with the magnetic device, resulting in low working efficiency.

[0006] Second, to avoid spillage, the edges of the conveyor belt of the belt conveyor are tilted under the support of rollers, and the cross-sectional shape is approximately U-shaped. However, after absorbing the debris, the existing magnetic suction device usually moves to the recovery box in a direction perpendicular to the belt conveyor in order to improve efficiency and shorten the reciprocating movement time, which makes it easy for the absorbed anchor rods to scratch the conveyor belt. Utility Model Content

[0007] The utility model proposes a crawler type iron suction device, the purpose of which is: 1. to solve the problem that the belt conveyor needs to stop intermittently during suction. 2. to reduce the scratches caused by the suctioned debris and the conveyor belt.

[0008] The technical solution of this utility model is as follows:

[0009] A crawler type magnetic magnet device comprises a frame arranged above a belt conveyor, a driving wheel and a driven wheel are respectively installed at the front and rear ends of the frame, and the driving wheel and the driven wheel are connected by a ring-shaped insulating crawler belt surrounding the outer side of the frame;

[0010] The front part of the frame is also equipped with two left and right electrode plates, which are respectively connected to the positive and negative electrodes of the power supply;

[0011] A number of electromagnetic modules are installed at intervals on the inner surface of the insulating track. The electromagnetic modules are in the shape of horizontal plates and move with the insulating track. Each group of electromagnetic modules is provided with brushes corresponding to two electrode plates. When the electromagnetic modules move below the electrode plates, each brush contacts the corresponding electrode plates.

[0012] As a further improvement of the crawler type magnetic absorption device: the angle between the moving direction of the insulating crawler and the conveying direction of the belt conveyor is 35 to 55 degrees.

[0013] As a further improvement of the crawler type magnetic absorption device: the angle between the moving direction of the insulating crawler and the conveying direction of the belt conveyor is 45 degrees.

[0014] As a further improvement of the crawler-type magnetic absorption device: the electromagnetic module includes an iron core and a coil wound around the outside of the iron core, and two ends of the coil are respectively connected to two brushes.

[0015] As a further improvement of the crawler type magnetic absorption device: an annular groove is provided in the middle of the iron core, and the coil is wound in the annular groove.

[0016] As a further improvement of the crawler type magnetic absorption device: an insulating plate spanning across the two ends of the annular groove is installed on the top of the iron core, and the brush is fixedly installed on the insulating plate.

[0017] As a further improvement of the crawler-type iron-absorbing device: the front end and the rear end of the electrode plate are both provided with an upwardly curved transition section.

[0018] As a further improvement of the crawler type magnetic suction device: the frame is also provided with auxiliary wheels for supporting the crawler.

[0019] Compared with the prior art, the utility model has the following positive effects:

[0020] 1. The utility model adopts a crawler belt method for uninterrupted continuous adsorption, and the belt conveyor can operate normally without intermittent stops, which significantly improves the work efficiency. At the same time, the driving device for controlling the overall reciprocating movement of the magnetic absorption device is omitted, reducing the cost.

[0021] 2. When the electromagnetic module moves to the front area close to the belt conveyor, the brush contacts the electrode plate to generate adsorption force. When it leaves the front area, the brush separates from the electrode plate, the adsorption force gradually disappears, and the adsorbed debris falls automatically, realizing the automatic switching of the magnetic state. It has the advantages of simple structure and easy control.

[0022] 3. The frame is arranged tilted relative to the belt conveyor. When the adsorbed anchor rod passes the edge of the conveyor belt, the two are no longer perpendicular, which can reduce scratches on the conveyor belt. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments.

[0028] like Figure 1 and 2 A crawler type magnetic magnet device includes a frame 6 hoisted above a belt conveyor. The frame 6 is welded by channel steel, steel plates and other components. The frame 6 is connected to the top plate of the transport channel through steel plates on both sides.

[0029] A driving wheel 1 and a driven wheel are respectively installed at the front and rear ends of the frame 6. The driving wheel 1 and the driven wheel are connected by a ring-shaped insulating crawler belt 2 around the outside of the frame 6.

[0030] The driving wheels 1 on both sides and the driven wheels on both sides are connected by axles. A driving motor 7 is also installed on the frame 6, and the driving motor 7 drives the axle of the driving wheel 1 to rotate through a transmission belt mechanism. The driving motor 7 is connected to an external power source through a cable.

[0031] A plurality of freely rotatable auxiliary wheels 5 are respectively installed on the left and right sides of the frame 6 for supporting and tensioning the insulating track 2 .

[0032] Two left and right electrode plates 3 are also installed at the front of the frame 6 , and the two electrode plates 3 are respectively connected to the positive pole and the negative pole of the power supply.

[0033] A plurality of electromagnetic modules 4 are installed at intervals on the inner surface of the insulating crawler 2 , and circulate along with the insulating crawler 2 .

[0034] like Figure 1 , 2, 3, the electromagnetic module 4 is in the shape of a horizontal plate, including an iron core 4-2. An annular groove is provided in the middle of the iron core 4-2, and both ends are connected to the insulating track 2 by bolts. The electromagnetic module 4 also includes a coil wound in the annular groove. An insulating plate 4-3 spanning both ends of the annular groove is installed on the top of the iron core 4-2. The insulating plate 4-3 is engineering plastic, and two copper brushes 4-1 are installed on the insulating plate 4-3. The brush 4-1 is curved and has a protrusion at the end. The two ends of the coil are respectively connected to the two brushes 4-1.

[0035] The positions of the two brushes 4 - 1 correspond to the two electrode plates 3 , respectively. When the electromagnetic module 4 moves below the electrode plates 3 , each brush 4 - 1 contacts the corresponding electrode plate 3 .

[0036] Further, such as Figure 1 The front and rear ends of the electrode plate 3 are both provided with an upwardly curved transition section to reduce the wear of the brushes.

[0037] Furthermore, the arrangement spacing of the electromagnetic modules 4 inside the insulating track 2 should be as small as possible so as not to affect the bending of the insulating track 2. At the same time, the winding directions of the coils of adjacent electromagnetic modules 4 can be opposite to reduce the mutual repulsion between them.

[0038] The driving wheel 1 , the driven wheel and the auxiliary wheel 5 are respectively arranged on both sides of the frame 6 , so as to reserve sufficient working space for the electromagnetic module 4 and the electrode plate 3 .

[0039] like Figure 4 The angle between the moving direction of the insulating crawler 2 of the crawler-type magnetic absorption device 200 and the conveying direction of the belt conveyor 100 is 35 to 55 degrees, preferably 45 degrees.

[0040] During operation, all electromagnetic modules 4 move in a circular motion with the insulating track 2. When a certain electromagnetic module 4 moves to the bottom of the electrode plate 3, the brush 4-1 contacts the electrode plate 3, and the electromagnetic module 4 is energized to generate magnetic attraction, so that the portion of the insulating track 2 below the electrode plate 3 can adsorb iron debris on the belt conveyor 100. The adsorbed debris moves outward with the insulating track 2. After leaving the area corresponding to the electrode plate 3, the magnetic attraction of the electromagnetic module 4 that adsorbs the debris begins to gradually weaken, and eventually the magnetic attraction disappears, and the debris automatically falls into the recycling box 300 below. Since the inner side of the entire insulating track 2 is provided with electromagnetic modules 4, the area directly above the belt conveyor 100 is always magnetic, and the area above the recycling box 300 is always non-magnetic, thereby achieving uninterrupted adsorption and automatic discharge.

[0041] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. The scope of the present invention is defined by the claims rather than the above description.
