Description

Technical Field

[0001] The utility model relates to the technical field of processing ore sticking in a mine car, in particular to a device for cleaning ore sticking in a mine car. Background Art

[0002] When the mine car is unloading ore, some ore powder will still adhere to the inner wall of the mine car, resulting in incomplete unloading. If the ore powder adhered to the inner wall of the mine car is not cleaned up, it will affect the subsequent loading capacity of the mine car and increase transportation costs. Therefore, it is necessary to deal with the ore powder adhered to the inner wall of the mine car.

[0003] The traditional method of dealing with ore stuck in mine cars is mainly manual operation, which uses crowbars or high-pressure air ducts for close cleaning. However, this method has high work intensity and low work efficiency. At the same time, due to the existence of structures such as chutes and screens near the curved track station, the risk factor is high when the workers are handling it, and safety accidents are prone to occur. In addition, with the current development of intelligent mining technology, it is a general trend to realize unmanned loading and unloading in the entire process.

[0004] In the prior art, the patent with publication number CN203666662U provides a device for cleaning the bottom of a mine car, which includes a frame, a turning frame arranged on the frame, a track for the mine car to move, a mine car fixing device arranged on both sides of the track, and a pneumatic hammer head for beating the mine car arranged in the turning frame, and the pneumatic hammer head is connected to an air compressor. Based on the structure of the device, after the turning frame rotates 180°, the opening of the bucket faces downward, and the pneumatic hammer head is driven by starting the air compressor to continuously beat the mine car, so that the sediment in the car body is vibrated and falls off by itself. After cleaning, the turning frame is reset to complete the cleaning of the bottom of the mine car.

[0005] However, the existing devices are mainly used to clean the bottom of the fully turned over mine car, and have high requirements for on-site civil engineering foundation and installation engineering. The mine cars at the curved track station are mainly unloaded sideways, and the existing devices are not suitable. Moreover, when the mine car is unloaded sideways, the single pneumatic hammer knocking method is difficult to achieve a good cleaning effect. In addition, the control method of the pneumatic hammer is also relatively cumbersome.

[0006] In view of this, it is necessary to design an improved mine car sticking ore cleaning device to solve the above problems. Utility Model Content

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0029] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0030] like Figure 1-3 As shown, the utility model provides a device for cleaning ore sticking in a mine car, comprising a mobile bracket 10, a chassis 20, a mobile mechanism, a hammer mechanism and a blowing mechanism; the mobile bracket 10 comprises at least one guide rod 11, the chassis 20 is arranged on the mobile bracket 10, and the mobile mechanism is used to drive the chassis 20 to move along the length direction of the guide rod 11; the hammer mechanism comprises a mounting plate 41 connected to the chassis 20, and a pneumatic hammer 42 connected to the mounting plate 41; the blowing mechanism comprises a blowing pipe 51 connected to a wind source.

[0031] Through the above method, the mobile mechanism can be used to drive the chassis 20 and the hammer mechanism and blowing mechanism connected to the chassis 20 to move as a whole along the length direction of the guide rod 11 of the mobile bracket 10, and the combined effect of hammering and air flow impact can be used to simply and efficiently remove the mineral powder adhered to the mine car 62 to meet the needs of actual applications.

[0032] In some embodiments of the utility model, the device for cleaning the sticky ore in the mine car can be used in a curved track station. Under this condition, the mobile bracket 10 is arranged above the unloading point of the mine car 62 in the curved track station, and a fixed bracket 61 connected to the mobile bracket 10 is arranged in the curved track station. Such an arrangement facilitates the effective cleaning of the sticky ore remaining in the side-discharging mine car 62 in the curved track station.

[0033] Specifically, in some embodiments of the present invention, the moving mechanism includes a driving wheel 31 and a driving assembly for driving the driving wheel 31 to rotate; the chassis 20 is provided with an opening 21 extending vertically therethrough, and the bottom of the driving wheel 31 passes through the opening 21 and is rollingly connected to the guide rod 11. More specifically, as Figure 3 As shown, in one embodiment of the utility model, the driving assembly is fixed on the upper surface of the chassis 20, and the mobile bracket 10 includes three parallel guide rods 11, the two outer guide rods 11 are slidably connected to the bottom of the chassis 20, and the middle guide rod 11 is rollingly connected to the driving wheel 31. In this way, when the driving assembly drives the driving wheel 31 to rotate, the driving wheel 31 rolls on the middle guide rod 11, thereby driving the chassis 20 to move along the length direction of the guide rod 11 as a whole. When installing the mobile bracket 10, it is preferred to keep the length direction of the guide rod 11 consistent with the length direction of the mine car 62, so that the chassis 20 and the hammer mechanism and the blowing mechanism connected to the chassis 20 can be driven by the mobile mechanism to move along the length direction of the mine car 62 as a whole, thereby comprehensively cleaning the mineral powder adhered to the inside of the mine car 62.

[0034] like Figure 4 As shown, in some embodiments of the present invention, the driving assembly includes a driving motor 32, a first bevel gear 33 connected to the output shaft of the driving motor 32, and a second bevel gear 34 meshing with the first bevel gear 33; the second bevel gear 34 is coaxially connected to the driving wheel 31. With such a configuration, when the output shaft of the driving motor 32 starts to rotate, the first bevel gear 33 and the second bevel gear 34 meshing with each other can be used to change the direction of the rotating shaft, and then the second bevel gear 34 can be used to drive the driving wheel 31 located on one side of the driving motor 32 to rotate. It should be noted that Figure 4 In order to observe the specific structure of the drive components, Figure 3 The protective shell 35, the air blowing pipe 51 and other partially shielded structures are hidden. In practical applications, the protective shell 35 can be set outside the first bevel gear 33 and the second bevel gear 34 as needed.

[0035] Please refer to Figure 5In some embodiments of the utility model, the mounting plate 41 includes a fixing portion and a mounting portion, the fixing portion is fixed on the chassis 20, and the mounting portion extends obliquely downward from the outer side of the fixing portion; the fixed end of the pneumatic hammer 42 is vertically arranged on the bottom surface of the mounting portion. With such an arrangement, the pneumatic hammer 42 can be tilted so as to fit the tilted state of the side wall of the mine car 62 during side unloading. The length of the mounting plate 41 and its tilt angle can be adjusted according to actual conditions, so that the telescopic end of the pneumatic hammer 42 can contact the side wall of the mine car 62. The type and specific structure of the pneumatic hammer 42 can be selected according to actual conditions, and it only needs to be able to achieve a striking effect through telescoping, and all belong to the protection scope of the utility model.

[0036] Preferably, the hammering mechanism further includes a first control component for controlling the pneumatic hammer 42, and the first control component is disposed on the chassis 20. Specifically, in some embodiments of the utility model, a pneumatic hammer 42 based on the control of the first control valve 43 is adopted, and the pneumatic hammer 42 can be driven to perform a striking operation by pressing the first control button 431 on the first control valve 43. In order to automatically press the first control button 431 more conveniently and efficiently, in some embodiments of the utility model, the first control component includes not only the first control valve 43 for controlling the pneumatic hammer 42, but also a reversing component for pressing the first control button 431 of the first control valve 43.

[0037] The first control valve 43 and the reversing assembly are both arranged on the chassis 20. The reversing assembly includes a reversing bracket 44 arranged on one side of the first control valve 43, and a reversing device 45 slidably connected to the reversing bracket 44 in a direction toward the first control button 431; the two ends of the reversing device 45 horizontally penetrate the two sides of the reversing bracket 44, and the end of the reversing device 45 close to the first control valve 43 and the top of the first control button 431 are both arranged as inclined surfaces. Based on this, when the reversing device 45 moves in a horizontal direction to contact the first control button 431, the inclined surface at the end of the reversing device 45 abuts against the inclined surface of the first control button 431, and the reversing device 45 continues to move in a direction close to the first control valve 43, thereby squeezing the first control button 431; when the reversing device 45 moves in a direction away from the first control valve 43, the first control button 431 can be released. With such arrangement, by controlling the commutator 45 to reciprocate in the horizontal direction, the pressing operation on the first control button 431 can be continuously repeated, thereby controlling the pneumatic hammer 42 to repeatedly perform the striking action.

[0038] Specifically, in some embodiments of the present invention, the reversing assembly further includes a reversing link 46 coaxially connected to the output shaft of the drive motor 32; a fixed block 461 is disposed on the outer side of the reversing link 46, and a first slide groove 451 is disposed in the middle of the commutator 45 in the vertical direction and is slidably connected to the fixed block 461. Based on this, when the output shaft of the drive motor 32 rotates, the reversing link 46 and the fixed block 461 on the reversing link 46 can be driven to rotate around the output shaft of the drive motor 32 as a whole, so that the fixed block 461 slides in the first slide groove 451, and drives the commutator 45 as a whole to move in the horizontal direction. Such an arrangement enables the moving mechanism and the hammering mechanism to be linked, so that the moving mechanism drives the chassis 20 to move as a whole while further driving the commutator 45 to reciprocate in the horizontal direction, thereby automatically and repeatedly pressing the first control button 431 during the movement of the chassis 20, so that the single-acting pneumatic hammer 42 can repeatedly perform the striking operation during the movement. The overall process has a high degree of automation, and the overall structure of the device is simple and easy to control.

[0039] In the process of using the pneumatic hammer 42 to hit the side wall of the mine car 62, the utility model also uses the air blowing pipe 51 to impact the mineral powder adhering to the inner wall of the mine car 62, effectively improving the effect of treating the sticky ore. The air blowing pipe 51 is connected to the wind source, which is preferably a high-pressure fan, so as to transmit the high-pressure wind to the mine car 62 to treat the sticky ore and improve the treatment efficiency.

[0040] In practical applications, in order to increase the impact force of the air flow of the air blowing pipe 51, the air outlet end of the air blowing pipe 51 needs to extend from the upper opening 21 of the mine car 62 into the mine car 62 and be as close to the inner wall of the mine car 62 as possible. Under this condition, after the cleaning is completed, even if the mine car 62 lifted up on the side is laid flat, the bottom end of the air blowing pipe 51 may still be located inside the mine car 62, which will affect the normal operation of the mine car 62. Therefore, in some embodiments of the utility model, the air blowing mechanism also includes a position adjustment component disposed on the chassis 20 and connected to the air blowing pipe 51. By setting the position adjustment component to adjust the position of the air blowing pipe 51, the air blowing pipe 51 can be placed at a lower position when it is necessary to clean the sticky ore, and the air blowing pipe 51 can be raised after the cleaning of the sticky ore is completed to avoid affecting the normal operation of the mine car 62.

[0041] Specifically, in some embodiments of the present invention, the position adjustment assembly includes a connector 52 connected to one end of the air blowing pipe 51, a fixing frame 53 and a pneumatic spring 54 arranged on the chassis 20; the fixing end of the connector 52 is rotatably connected to the top of the fixing frame 53, and a second slide groove 521 is provided on the outer side of the fixing end of the connector 52; the pneumatic spring 54 is extended and retracted in the vertical direction, and a slider 541 is provided at the retractable end of the pneumatic spring 54, and the slider 541 is slidably connected to the second slide groove 521. In this way, as the pneumatic spring 54 is extended and shortened, the slider 541 can slide in the second slide groove 521, thereby driving the connector 52 to rotate around the top of the fixing frame 53. The air blowing pipe 51 used in the present invention is a rigid air blowing pipe 51, which can rotate around the top of the fixing frame 53 as a whole with the rotation of the connector 52, thereby changing the position of the air blowing pipe 51.

[0042] More preferably, Figure 1 As shown, in one embodiment of the utility model, the air blowing pipe 51 includes a first straight pipe, a second straight pipe and a third curved pipe which are connected in sequence; the first straight pipe is connected to the connecting member 52 and is on the same horizontal plane as the connecting member 52; the second straight pipe is perpendicular to the first straight pipe and extends downward; the third curved pipe is semicircular, and the convex direction is toward the pneumatic hammer 42; a plurality of air outlet holes 511 are arranged on the outer wall of the third curved pipe, so as to perform air flow impact on different positions of the mine car 62 at one time, thereby improving work efficiency. Based on this, when the second straight pipe is kept vertical, the bottom end of the third curved pipe is at the lowest position, which can effectively clean the mineral powder inside the mine car 62; when the pneumatic spring 54 contracts, it drives the air blowing pipe 51 to rotate counterclockwise around the top of the fixing frame 53 as a whole, so that the connection point between the first straight pipe and the second straight pipe and the connection point between the second straight pipe and the third curved pipe are both raised, and the bottom of the third curved pipe is upturned, and the bottom end position of the air blowing pipe 51 is significantly raised, which is convenient for the mine car 62 to pass smoothly.

[0043] In some embodiments of the utility model, the telescopic state of the pneumatic spring 54 is controlled by the second control valve 55. When the second control button 551 on the second control valve 55 is pressed, the pneumatic spring 54 contracts, the bottom position of the air blowing pipe 51 is raised, and the mine car 62 can pass smoothly; when the second control button 551 is released, the pneumatic spring 54 extends, and the bottom position of the air blowing pipe 51 drops to fit the bottom of the mine car 62 more closely. In order to more efficiently control the telescopic state of the pneumatic spring 54, the second control valve 55 is arranged on the chassis 20, and the end of the second control button 551 of the second control valve 55 extends to the outside of the chassis 20; a protrusion for abutting the second control button 551 is arranged at the end of the mobile bracket 10 opposite to the second control button 551. In this way, when the chassis 20 moves to the end of the mobile bracket 10 close to the second control button 551, it indicates that the cleaning is completed, the second control button 551 abuts against the protrusion at the end of the mobile bracket 10, the second control button 551 is squeezed, the air pipe 51 is lifted, and the mine car 62 can pass normally after being reset.

[0044] The working principle of the mine car sticking ore cleaning device provided by the utility model is specifically described below:

[0045] Please refer to Figure 5 The device for cleaning ore stuck in a mine car provided by the utility model can be used in a curved track station. When the mine car 62 enters the lane 65 of the curved track station, the side of the mine car 62 away from the curved track 63 is fixed, and the side close to the curved track 63 is lifted by the hook 64. The mine car 62 is in a lateral tilt state, and the movable box plate 621 on the side of the mine car 62 away from the curved track 63 is opened, so that the ore in the mine car 62 falls into the chute 66 at the bottom, completing the unloading operation. At this time, there is still some adhered ore powder inside the mine car 62, which can be cleaned by using the device for cleaning ore stuck in a mine car provided by the utility model.

[0046] By setting a fixed bracket 61 in the curved track station and connecting the mobile bracket 10 in the mine car sticking ore cleaning device provided by the utility model to the fixed bracket 61, the device is located above the ore unloading point of the mine car 62, and the installation of the device is completed. In the initial state, the chassis 20 is located at one end of the length direction of the mobile bracket 10, and the second control button 551 is in a squeezed state, and the air blowing pipe 51 is lifted. When cleaning is required, the drive motor 32 and the fan connected to the air blowing pipe 51 are started to move the chassis 20 toward the other end of the movable bracket 10, and the second control button 551 is released, and the air blowing pipe 51 falls into the interior of the mine car 62 to impact the dust in the mine car 62 with air flow; at the same time, during the movement of the chassis 20, the drive motor 32 also drives the commutator 45 to reciprocate in the horizontal direction through the reversing connecting rod 46, and repeatedly presses the first control button 431, so that the pneumatic hammer 42 repeatedly knocks the side wall of the mine car 62 during the movement; when the chassis 20 moves to the end of the movable bracket 10, the drive motor 32 is controlled to rotate in the opposite direction, and then the chassis 20 is moved to the initial position, completing a round-trip cleaning of the entire mine car 62, at which time the second control button 551 is squeezed again, the air blowing pipe 51 is lifted, the drive motor 32 and the fan are turned off, and the sticky ore treatment is completed.

[0047] In the above manner, the mine car sticking ore cleaning device provided by the utility model can use the moving mechanism to drive the chassis 20 and the hammer mechanism and the blowing mechanism connected to the chassis 20 to move as a whole along the length direction of the guide rod 11 of the moving bracket 10, and use the combined effect of hammering and air flow impact to simply and efficiently remove the ore powder adhered in the mine car 62. During the movement of the chassis 20, the first control button 431 of the first control valve 43 can be automatically pressed, and the position of the blowing mechanism can be automatically adjusted after the cleaning is completed to avoid it affecting the normal operation of the mine car 62. The overall process has a high degree of automation, and the overall structure of the device is simple and easy to control. It has a good application prospect for cleaning sticking ore after unloading the side-unloading mine car 62 in the curved track station.

[0048] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
