Description

Technical Field

[0001] The present disclosure relates to the field of mining technology, and in particular, to a dredging device for a mine. Background Art

[0002] The content of impurities such as coal slime in mine sewage is relatively high. During the operation of the main drainage system, the impurities in the sewage will cause varying degrees of wear and damage to the drainage pumps, drainage pipes and other facilities, resulting in a shortened service life of the main drainage facilities and an increased failure rate of the main drainage facilities. At the same time, the treatment of coal slime water mixed with coal slime is difficult and costly, and it occupies the effective volume of the water tank, resulting in frequent silt removal work in the main and auxiliary water tanks.

[0003] In the related technologies, the coal slurry water is mostly cleaned by manual bucketing, high-power mud pump extraction, and crawler silt remover shoveling. Among them, because the height of the accumulated coal slurry water blocks is about 2 to 3 meters, it is easy to bury the workers or auxiliary machinery when it collapses or leaks instantly. The temporary blocking facilities used often have no effective support attachment points and cannot withstand the impact of excessive coal slurry water, posing a serious safety threat. At the same time, the silt remover shovel operation range is narrow, and manual operation is difficult. The coal slurry water is easily scattered along the way during transportation, which causes secondary pollution to the mine tunnels, making the cleaning efficiency low. Utility Model Content

DETAILED DESCRIPTION

[0032] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

Figure 2 , the left direction in the figure is the front direction of the vehicle body, the right direction is the rear direction of the vehicle body, and the "lateral direction" refers to the two lateral directions of the vehicle body along the direction of travel, refer to Figure 2 , the up-down direction shown in the figure is the lateral direction of the vehicle body. In addition, the terms "first", "second", etc. used in the present disclosure are to distinguish one element from another element, and do not have order and importance.

[0034] refer to Figures 1 to 3 The present disclosure exemplarily provides a desilting device for a mine, including a vehicle body 10, a suspension rod assembly 20, a baffle assembly 30 and a pumping assembly 40. A sludge storage tank 11 may be provided inside the vehicle body 10 for accommodating and settling the cleaned materials; a suspension rod assembly 20 may be arranged at the front of the vehicle body 10 and cantilevered forward, wherein the suspension rod assembly 20 may include a suspension arm 21, and the suspension arm 21 may have a first end 211 away from the vehicle body 10, and a vibrating rod may be suspended at the first end 211 for vibrating to cause the coal sludge layer to collapse and form coal sludge water, which is the main cleaning object of the device; a baffle assembly 30 may include a first baffle 31 provided at the front end of the vehicle body 10 and a second baffle 32 rotatably connected to both sides of the first baffle 31 along the side of the vehicle body 10, and a coal sludge water inlet 311 may be opened near the bottom of the first baffle 31; and a pumping assembly 40 may be connected between the coal sludge water inlet 311 and the sludge storage tank 11, and is used to pump the coal sludge water from the coal sludge water inlet 311 into the sludge storage tank 11.

[0035] In the above embodiment, the boom 21 can be extended forward from the front end of the vehicle body 10 so that the vibrating rod suspended from the first end 211 of the boom 21 has enough range to contact the accumulated coal slime layer. The coal slime layer here is formed by the accumulation of a large amount of coal slime material with poor fluidity in the coal slime water. After being driven by the vibration of the vibrating rod, it can collapse and re-form coal slime water with good fluidity for subsequent treatment, and there is no need to actively pass water to the coal slime layer for mixing, so as to avoid increasing the range and volume of the material to be cleaned and increase unnecessary workload. Among them, the coal slime water can be blocked at the front end of the vehicle body 10 by the baffle assembly 30, and the baffle assembly 30 is composed of a first baffle 31 and a second baffle 32 rotatably connected to both sides thereof along the side of the vehicle body 10, and the second baffle 32 can be rotated relative to the first baffle 31 when the working conditions require, so as to expand or reduce the blocking range of the coal slime water. During this process, the baffle assembly 30 can also actively cause the coal slurry water to tend to accumulate at the front end of the vehicle body 10 as the vehicle body 10 slowly moves forward. At this time, the coal slurry water can pass through the coal slurry water inlet 311 located near the bottom end of the first baffle 31, and through the pumping action of the pumping assembly 40, it can be sucked into the slurry storage tank 11 from the front end of the vehicle body 10 to absorb and contain the coal slurry water, thereby effectively reducing and cleaning the coal slurry volume at the front end of the vehicle body 10.

[0036] It should be noted here that if the volume of the coal sludge water is small, the sludge storage tank 11 can be set on the vehicle body 10 as a mobile container to accommodate the coal sludge water, so as to obtain better flexibility of use. At this time, the sludge storage tank 11 can be set as a structure that can be flipped or tilted relative to the vehicle body 10, so that when a dredging operation is completed or the coal sludge water capacity reaches the maximum value, the coal sludge water can be unloaded to a centralized treatment point. Furthermore, the sludge storage tank 11 can also be used as a transfer structure. A sewage pipe connected to a centralized treatment point can be set on the wall of the pool near the bottom of the sludge storage tank 11. When performing the coal sludge water absorption operation, the sludge storage tank 11 can first temporarily accommodate the coal sludge water, and then discharge the coal sludge water to a centralized treatment point through the sewage pipe. This setting can process a large amount of coal sludge water to increase the dredging volume and dredging capacity of the device.

[0037] Through the above technical scheme, the vibrating rod in the suspension rod assembly 20 in the dredging device can drive the accumulated coal slime layer to collapse to form coal slime water with good fluidity. The baffle assembly 30 can block the coal slime water to the front of the vehicle body 10, and suck the coal slime water into the slime storage tank 11 of the vehicle body 10 through the coal slime water inlet 311 and the pumping assembly 40 connected thereto, so as to achieve dredging. The process is safe and reliable, and the dredging effect is ideal.

[0038] According to some embodiments, Figure 1 and Figure 3As shown, a mounting groove 23 may be formed on the vehicle body 10, and the suspension rod assembly 20 may include a support arm 22, one end of the support arm 22 may be rotatably connected to the mounting groove 23, and the other end may be rotatably connected to the suspension arm 21, wherein an avoidance space may be provided inside the mounting groove 23 for avoiding the swinging movement of the support arm 22 along the moving direction of the vehicle body 10, and the support arm 22 may be constructed as a retractable structure.

[0039] In the above embodiment, the mounting groove 23 can be a groove-shaped structure formed integrally with the outer shell of the vehicle body 10, or it can be a separate groove-shaped part and fixedly connected to the outer shell of the vehicle body 10. Here, the present disclosure does not specifically limit the connection method between the two, including but not limited to the use of welding, bolting, bonding or snap-fitting, etc., and it is only necessary to ensure that the mounting groove 23 is not easy to fall off relative to the outer shell of the vehicle body 10 when connected to the outer shell of the vehicle body 10.

[0040] Among them, the installation groove 23 is provided with an avoidance space along the travel direction of the vehicle body 10, and one end of the support arm 22 rotatably connected to the installation groove 23 can rotate in the travel direction of the vehicle body 10 within the range of the avoidance space, so as to drive the support arm 22 and the suspension arm 21 connected to the other end of the support arm 22 to realize a swinging motion. Since the first end 211 needs to drive the suspension arm 21 to produce a certain displacement in the up-down direction when lifting, the connection between the suspension arm 21 and the support arm 22 will also produce a displacement change accordingly. The avoidance space in the installation groove 23 can support a small displacement of the connection between the support arm 22 and the suspension arm 21 by avoiding the small-range swinging motion of the support arm 22, thereby meeting the lifting and lowering requirements of the first end 211 of the suspension arm 21 in the up-down direction. Specifically, the avoidance space can make the support arm 22 swing in a small range, and the swing amplitude of the support arm 22 is between -15° and 15°, so as to provide a reasonable swinging requirement of the support arm 22 and avoid excessive displacement of the center of gravity of the suspension arm 21 caused by excessive swing amplitude, resulting in reduced overall stability of the suspension assembly 20.

[0041] At the same time, the arm 22 can be constructed as a telescopic structure, for example, using a telescopic rod or a telescopic cylinder structure as the main body of the arm 22, which can increase or shorten the length of the arm 22 to further expand the lifting range of the first end 211 in the up and down directions, thereby increasing the volume of the coal slime layer that can be processed by the device.

[0042] In some embodiments, the boom 21 may also be constructed as a retractable structure, and the first end 211 may be extended forward of the vehicle body 10, thereby increasing the extension distance of the first end 211, allowing for cleaning of coal slime layers farther away, thereby expanding the scope of use, and being retracted in a normal state when not in operation to reduce the extension distance, thereby reducing the volume occupied by the limited space in the mine. The telescopic structure may use a multi-section telescopic rod or a multi-stage telescopic cylinder.

[0043] For example, Figures 1 to 3As shown, the boom 21 may have a second end 212 opposite to the first end 211, and the second end 212 may be configured to be able to rotate horizontally around the connection between the boom 21 and the support arm 22, wherein the second end 212 may be supported on the vehicle body 10 by a bracket 25, and a guide rail 26 is provided at the top end of the bracket 25, and the guide rail 26 may be constructed as an arc-shaped guide rail with the same arc as the rotation trajectory of the second end 212, and the second end 212 may be configured to slide along the guide rail 26 when rotating.

[0044] In the above embodiment, the support arm 22 can be connected between the first end 211 and the second end 212 of the suspension arm 21, and the second end 212 can rotate horizontally relative to the connection between the suspension arm 21 and the support arm 22, thereby driving the suspension arm 21 to rotate at multiple angles in the horizontal direction with the connection as the axis, so as to expand the swing range of the first end 211. At the same time, the bracket 25 fixed on the vehicle body 10 can provide normal support for the second end 212, and the guide rail 26 set at the top of the bracket 25 is an arc-shaped guide rail, and has the same arc as the rotation track of the second end 212, so that the second end 212 can slide along the guide rail 26 when rotating, thereby limiting the rotation range of the second end 212.

[0045] In some embodiments, Figure 3 and 4 As shown, the suspension rod assembly 20 may also include a handle 27, which may be inserted into the guide rail 26 and connected to the second end 212, and is used to drive the boom 21 to rotate relative to the support arm 22. The portion of the handle 27 that is inserted into the guide rail 26 may be gap-matched with the guide rail 26 in the up-down direction, providing a certain amount of movement margin for the handle 27 to swing in the up-down direction. The operator may drive the boom 21 to swing at multiple angles by holding and turning the handle, so that the first end 211 may drive the vibrating rod to loosen the coal slime layer during the swing. In other embodiments, the horizontal arc guide rail 26 shown in the figure may also be installed on a vertical arc guide rail so as to be movable up and down, and the vertical guide rail is arranged on the bracket 25, so that the up-and-down swing may slide along the vertical arc guide rail.

[0046] According to some embodiments, Figure 3 and Figure 4 As shown, a limit member 28 can also be provided on the guide rail 26. The limit member 28 and the handle 27 are respectively provided on both sides of the guide rail 26, and the two maintain a certain gap with the guide rail 26, so that the boom 21 has a certain swing margin when swinging in the up and down directions. The part between the limit member 28 and the handle 27 can swing slightly in the up and down directions, and abut against the limit member 28 or the handle 27 when reaching the maximum swing amplitude, respectively, and is limited by the swing amplitude of the two, thereby ensuring the stability of the overall swing of the suspension rod assembly 20.

[0047] For example, Figure 3As shown, a lifting ring 213 can be provided at the bottom of the second end 212 for mounting a counterweight to balance the weight of the first end 211 and the second end 212 of the boom 21, so that the second end 212 of the boom 21 can be stably supported on the bracket 25 when the boom 21 is in a normal state and is not prone to overturning.

[0048] In some embodiments, Figure 1 and Figure 2 As shown, the baffle assembly 30 may include a first oil cylinder 33, and the cylinder barrel of the first oil cylinder 33 may be fixed to the front end of the vehicle body 10, and the piston rod of the first oil cylinder 33 may be fixedly connected to the first baffle 31, wherein the first oil cylinder 33 is configured to lift the first baffle 31 relative to the vehicle body 10 when the piston rod is extended. In this embodiment, the two ends of the first oil cylinder 33 are respectively connected to the front end of the vehicle body 10 and the side of the first baffle 31 away from the coal slurry water, and can be used to support the first baffle 31 to rise or fall in the up and down direction to block the coal slurry water.

[0049] According to some embodiments, Figure 1 and Figure 2 As shown, the vehicle body 10 may be provided with an anti-slip groove 12, and a first baffle 31 is provided with an anti-slip plate 312 on one side facing the vehicle body 10, and the anti-slip plate 312 is configured to slide along the inner wall of the anti-slip groove 12 when the first baffle 31 is lifted. Among them, the anti-slip plate 312 has a limiting structure arranged inside the anti-slip groove 12 to prevent the two from being relatively separated. When the first baffle 31 moves in the up and down directions, the anti-slip plate 312 can slide along the inner wall of the anti-slip groove 12 to limit the displacement of the first baffle 31 in the front and rear directions of the vehicle body 10, avoid overturning, and improve the overall stability of the vehicle body 10. At the same time, the anti-slip groove 12 can be used to provide support for the first baffle 31. When the first baffle 31 bears more weight of coal slurry water, the anti-slip groove 12 can provide it with a stable support force, thereby improving the load-bearing capacity of the first baffle 31. In other embodiments, the vehicle body 10 itself may be provided with a brake assembly for firmly supporting the vehicle body 10 on the ground when the vehicle body 10 stops moving. At this time, the anti-slip groove 12 can transfer part of the weight of the coal slurry water borne by the vehicle body 10 after the brake assembly is activated to the ground, thereby further improving the overall load-bearing capacity of the vehicle body while ensuring the overall stability of the vehicle body.

[0050] For example, a plurality of corresponding bolt holes may be respectively provided on the anti-slip groove 12 and the first baffle plate 31, so that when the first baffle plate 31 is lifted to a suitable position, the two can be bolted and fixed by fixing bolts, thereby further improving the stability between the two and the load-bearing capacity of the first baffle plate 31.

[0051] In some embodiments, Figure 1 and Figure 2As shown, the baffle assembly 30 may further include a second cylinder 34, the cylinder barrel of the second cylinder 34 may be hinged to both sides of the lateral direction of the vehicle body 10, and the piston rod of the second cylinder 34 may be hinged to the second baffle 32, wherein the second cylinder 34 may be configured to cause the second baffle 32 to rotate horizontally toward the front side of the vehicle body 10 relative to the first baffle 31 when the piston rod is extended. In this embodiment, the cylinder barrel of the second oil cylinder 34 is hinged on both sides of the vehicle body 10, and the piston rod of the second oil cylinder 34 is hinged to the side of the second baffle 32 facing the vehicle body 10. The rotation of the second baffle 32 relative to the first baffle 31 can be achieved by controlling the dispensing action of the piston rod of the second oil cylinder 34. The second oil cylinders 34 respectively arranged on both sides of the vehicle body 10 can act independently of each other, and the rotation of a second baffle 32 on one side of the first baffle 31 can be controlled separately. In some narrow lanes or special working conditions under the mine, the second oil cylinder 34 and the corresponding second baffle 32 on any side can be freely opened, which is convenient to use and can be applied to a variety of working environments. In this embodiment, the second baffle 32 can be detachably connected to the second oil cylinder 34 to facilitate the independent installation of the second baffle 32 and the second oil cylinder 34.

[0052] In other embodiments, the second baffle 32 may also be detachably connected to the first baffle 31, wherein a pin seat that docks with each other may be provided between the second baffle 32 and the first baffle 31, and when the pin seats of the two are coaxially aligned, the pin seats of the two are simultaneously penetrated by inserting a plug, so that the second baffle 32 can be rotatably connected relative to the first baffle 31. At this time, the plug forms the rotation axis of the second baffle 32, and the second baffle 32 can be relatively independently disassembled by plugging and pulling the plug, so that the second baffle 32 with different extension sizes can be selected according to the different needs of the use site, so as to effectively block and isolate the coal slurry water, and the use is more flexible.

[0053] According to some embodiments, Figure 1 and Figure 2 As shown, the bottom of the first baffle 31 and the second baffle 32 can be provided with a third baffle 35 for blocking the coal slurry water from reaching the front side of the vehicle body 10, and the third baffle 35 can be made of rubber material, has good flexibility, and can make a small adaptive contour shape change when in contact with the ground or the walls on both sides of the mine tunnel, so as to improve the blocking effect of the coal slurry water, and prevent the coal slurry water from crossing the third baffle 35 and overflowing to the surrounding area of ​​the vehicle body 10, which brings difficulty to the cleaning work. The disclosed embodiment does not impose specific restrictions on the connection method between the third baffle 35 and the first baffle 31 or the second baffle 32, including but not limited to the use of bolts, bonding or snap connections, etc., only need to ensure that the connection between the third baffle 35 and the first baffle 31 or the second baffle 32 is fixed and reliable and not easy to fall off, and the third baffle 35 should at least partially protrude from the edge of the first baffle 31 and the second baffle 32 to further ensure the blocking effect of isolating the coal slurry water from the front side of the vehicle body 10.

[0054] In some embodiments, Figure 1 , Figure 2 and Figure 5 As shown, the pumping assembly 40 may include a third oil cylinder 41 and two fourth oil cylinders 42. The piston rod of the third oil cylinder 41 may be a two-way rod 411, and the two ends of the two-way rod 411 may be respectively extended from the two ends of the third oil cylinder 41; the piston rods of the two fourth oil cylinders 42 may be unidirectional rods 421, and the two unidirectional rods 421 may be respectively fixedly connected to the two ends of the two-way rod 411.

[0055] In this embodiment, the third oil cylinder 41 is a driving oil cylinder for outputting driving force, and the two fourth oil cylinders 42 are coal slurry water pumping oil cylinders for sucking or discharging coal slurry water, and are respectively arranged on both sides of the third oil cylinder 41, and are lever-connected with the two-way rod 411 in the third oil cylinder 41, so that when the two-way rod 411 of the third oil cylinder 41 changes its action, it can simultaneously drive the two unidirectional rods 421 on both sides to move in the same direction, thereby causing the respective chambers of the two fourth oil cylinders 42 to simultaneously form volume changes. Figure 5 In the figure, when the bidirectional rod 411 moves to the left side as shown in the figure, the two unidirectional rods 421 on both sides move in the same direction to the left side. At this time, the volume of the A chamber of the fourth oil cylinder 42 on the left side is reduced, and the pumping action is performed, and the volume of the B chamber is increased, and the pumping action is performed. Similarly, the volume of the C chamber of the fourth oil cylinder 42 on the right side is reduced, and the pumping action is performed, and the volume of the D chamber is increased, and the pumping action is performed.

[0056] For example, Figure 1 , Figure 2 and Figure 5 As shown, a first pipe 13 can be connected between the pumping component 40 and the coal slurry water inlet 311, and a second pipe 14 can be connected between the pumping component 40 and the sludge storage tank 11, wherein two chambers of the fourth oil cylinder 42 can be respectively provided with water outlets 422, and the water outlet 422 of one fourth oil cylinder 42 can be selectively connected to the first pipe 13, and the water outlet 422 of another fourth oil cylinder 42 can be selectively connected to the second pipe.

[0057] In this embodiment, each of the two chambers of the fourth oil cylinder 42 is provided with a water inlet 422. When one of the chambers performs a pumping action, the water inlet 422 corresponding to the chamber is connected to the first pipe 13 to absorb the coal slurry water at the front end of the vehicle body 10 from the coal slurry water inlet 311. At this time, the other chamber synchronously performs a pumping action, and the other water inlet 422 corresponding to the chamber is connected to the second pipe 14 to discharge the coal slurry water from the chamber into the slurry storage tank 11. The above process is realized in one stroke of the one-way rod 421. When the stroke direction of the one-way rod 421 changes, the chamber that originally performs the pumping action changes to perform the pumping action, and the corresponding water inlet 422 changes from being connected to the first pipe 13 to being connected to the second pipe 14. Similarly, the other chamber and its corresponding water inlet 422 undergo a relative reverse change, thereby ensuring that the pumping assembly 40 can continuously perform the coal slurry water absorption and discharge actions.

[0058] For example, Figure 5 In the embodiment, when chamber A performs a pumping action, the a water inlet is connected to the second pipe 14, and the coal slurry water in chamber A is discharged into the slurry storage tank 11. At this time, chamber B performs a pumping action synchronously, and the b water inlet is connected to the first pipe 13, and the coal slurry water is sucked from the coal slurry water inlet 311. Similarly, when chamber A performs a pumping action, chamber C performs a pumping action synchronously, and the c water inlet is connected to the second pipe 14, and the coal slurry water in chamber C is discharged into the slurry storage tank 11. At this time, chamber D performs a pumping action synchronously, and the d water inlet is connected to the first pipe 13, and the coal slurry water is sucked from the coal slurry water inlet 311.

[0059] In some embodiments, Figure 2 As shown, there can be multiple pumping assemblies 40, and the multiple pumping assemblies 40 can be respectively fixed on both sides of the vehicle body 10, so as to maximize the use of the space on both sides of the vehicle body 10 to absorb and transfer the coal slurry water, improve the cleaning efficiency of the coal slurry water, and balance the weight on both sides of the vehicle body 10 in the lateral direction to improve the stability of the vehicle body 10.

[0060] The preferred embodiments of the present disclosure are described in detail above with reference to the accompanying drawings. Figure 6 In S101, the baffle assembly 30 can be rotated to the front end of the vehicle body 10. Specifically, the first baffle 31 is lifted to a preset position and fixed relatively to the anti-slip groove 12, and then the second baffle 32 is rotated toward the front of the vehicle body 10 relative to the first baffle 31 to expand the blocking range of the baffle assembly 30 for the coal slurry water. After the baffle assembly 30 is reliably positioned, in S102, the suspension rod assembly 20 can be extended into the coal slurry layer, and the coal slurry layer can be vibrated by a vibrating rod so that the coal slurry layer collapses under the action of vibration and reforms the coal slurry water. In S103, the coal slurry water at the front end of the baffle assembly 30 is pumped to the slurry storage tank 11 by the pumping assembly 40 to achieve the cleaning and absorption effect of the coal slurry water.

[0061] When the suspension rod assembly 20 extends into the coal slime layer and vibrates the coal slime layer through the vibrating rod, Figure 7 The step of S102 may include: in S201, when the suspension arm assembly 20 vibrates the coal slime layer, the arm 22 may be first extended and retracted to allow the vibrating rod to extend to a preset depth in the coal slime layer; in S202, the suspension arm 21 may be horizontally rotated to expand the processing range of the coal slime layer by the suspension arm assembly 20, and this process may be achieved by the operator holding the handle 27 to drive the suspension arm 21 to rotate. Wherein, when the suspension arm 21 is retractable, the suspension arm 21 may be extended and retracted to a suitable position before S201 and then the S201 operation may be performed.

[0062] The present disclosure is not limited to the specific details of the above-mentioned embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.

[0063] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0064] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
