Description

Technical Field

[0001] This invention belongs to the field of coal mine electromechanical technology, and particularly relates to a coal mine electromechanical transportation device. Background Technology

[0002] In coal mine production systems, electromechanical transport equipment plays a crucial role in coal transportation and handling. Compared to traditional manual handling methods, these electromechanical transport devices offer significant advantages: 1) High efficiency, significantly shortening the transportation cycle through continuous operation; 2) Economy, reducing manpower input and effectively lowering labor costs; 3) Safety, reducing the risk of accidents caused by human error and ensuring miners' safety; 4) Environmental adaptability, able to cope with the harsh working conditions of high temperature, high humidity, and high dust levels underground, ensuring stable equipment operation. These advantages have led to the widespread application of electromechanical transport equipment in coal mine production, playing a positive role in improving coal mine production efficiency and safety.

[0003] However, during transshipment and transportation, coal typically accumulates inside equipment or on the surface of conveyor belts due to gravity. Because of friction and voids between coal particles, this accumulation is often loose, resulting in low utilization of the effective load per unit volume. This loose state not only wastes transportation resources and increases unnecessary transportation frequency and energy consumption, but also exacerbates the risk of blockages and coal dust at transshipment points, thus hindering further reductions in transportation costs and improvements in production efficiency. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a coal mine electromechanical transportation device, thereby solving the technical problem that the coal has low stacking density and a relatively loose stacking state during transportation, resulting in a low effective load utilization rate per unit volume.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0008] This invention provides a coal mine electromechanical transportation device, including a car body, a coal shoveling assembly, and a coal pressing assembly. The upper end of the car body is open. The coal shoveling assembly is located at the front of the car body and is used to shovel coal and transport it through the upper end of the car body into the car body. The coal pressing assembly includes a lower pressing member, which is movable along the front-rear direction and vertically movable inside the car body. The lower pressing member can be moved to a clearance state and a working state. When the lower pressing member is in the clearance state, it is located on the upper rear side of the car body, and the coal shoveling assembly can transport coal through the upper front side of the car body into the car body. When the lower pressing member is in the working state, it can move along the front-rear direction and vertically movable to compact the coal inside the car body.

[0009] Furthermore, the coal pressing assembly also includes a support component, which spans the side plates on both sides of the vehicle body. The outer sides of both side plates are provided with slide rails extending horizontally in the front-to-back direction. Multiple pulleys are provided on the lower sides of both sides of the support component. The pulleys on both sides slide and engage with the slide rails on their respective sides to support the support component above the vehicle body and drive the support component to slide back and forth along the slide rails. The support component is movably connected to the lower pressing component, allowing the lower pressing component to move up and down relative to the support component in the vertical direction.

[0010] Furthermore, locking blocks are provided on both the left and right sides of the support member. The locking blocks are C-shaped. The support member includes a first plate and a second plate that are spaced apart vertically. An installation space that matches the locking blocks is formed between the first plate and the second plate. The locking blocks have inward openings and their upper ends are inserted into the installation space and fixedly connected to the second plate. The lower end of the locking blocks abuts against the bottom of the slide rail. The locking blocks can slide back and forth along the slide rail with the support member.

[0011] Furthermore, multiple first hydraulic cylinders are installed in the support member. The fixed end of the first hydraulic cylinder is fixedly connected to the support member, and the telescopic end of the first hydraulic cylinder passes downward through the support member and is fixedly connected to the lower pressing member. The first hydraulic cylinder can drive the lower pressing member to move up and down.

[0012] Furthermore, a movable door for opening and closing the rear of the vehicle body is provided at the rear end; scrapers are provided at both the front and rear ends of the lower pressure member. The lower pressure member is a U-shaped component with a flat plate. A groove extending vertically is provided on the outer side of the side plate of the lower pressure member. The scraper is a steel component with an L-shaped cross section. The openings of the two scrapers are arranged opposite each other. A slider that slides with the groove is provided on the inner side of the vertical plate of the scraper. The two scrapers can move up and down independently relative to the lower pressure member, and the scrapers can move along the front and rear direction of the vehicle body with the lower pressure member. When unloading, the movable door is opened, and the scrapers can descend relative to the lower pressure member and move towards the rear of the vehicle body with the lower pressure member to push the coal out from the rear end of the vehicle body.

[0013] Furthermore, the lower edge of the movable door is hinged to the vehicle body floor, and a third telescopic arm is also provided between the movable door and the vehicle body. The third telescopic arm can drive the movable door to rotate around the lower edge of the movable door to open and close the movable door.

[0014] Furthermore, a second hydraulic cylinder is provided on the outer side of each of the two side plates. The fixed end of the second hydraulic cylinder is fixedly connected to the side plate of the corresponding side, and the telescopic end of the second hydraulic cylinder is fixedly connected to the cross plate of the scraper on the corresponding side. The second hydraulic cylinder can drive the scraper on the corresponding side to move up and down relative to the lower pressure member. When the second hydraulic cylinder extends to its maximum stroke, the bottom wall of the cross plate is flush with the bottom wall of the pressure plate. A limit plate is provided at the top of the slider, and the limit plate can be locked on the upper end of the side plate.

[0015] Furthermore, the coal shoveling assembly includes a bucket and a shovel. The bucket is hinged to the vehicle body via a first telescopic arm, which can drive the bucket to tilt up and down. A second telescopic arm is also provided between the bucket and the vehicle body, which can drive the bucket to move back and forth to scoop up coal. The shovel is hinged to the front end of the bucket so that the shovel swings upward relative to the bucket to hook up coal.

[0016] Furthermore, when the first telescopic boom extends to its maximum stroke, the bucket flips to its maximum angle position, and this position does not interfere with the coal pressing component.

[0017] Furthermore, tracks are installed on both sides of the bottom of the vehicle body.

[0018] (III) Beneficial Effects

[0019] The beneficial effects of this invention are:

[0020] This invention discloses a coal mine electromechanical transport device. A coal compaction assembly is installed on the vehicle body. The lower compactor of the coal compaction assembly can move to both a clearance state and a working state. When the lower compactor is in the clearance state, it is located on the upper rear side of the vehicle body, allowing the coal shoveling assembly to transport coal from the upper front side of the vehicle body into the interior. When the lower compactor is in the working state, it can move along the front-rear direction of the vehicle body and move vertically. Compared to existing technologies, this device achieves mechanical compaction of loosely piled coal inside the vehicle body, significantly reducing the coal's volume and increasing the density of coal filling on the transport equipment. This increases the effective load per transport and improves transport efficiency. Furthermore, after compaction, the internal voids of the coal are significantly reduced, reducing energy loss caused by loose coal movement during transport and achieving a decrease in unit transport energy consumption under the same transport conditions. In addition, compaction reduces dust and coal spillage during transport, lowering the generation and dispersion of coal dust, improving air quality inside the mine, and contributing to a cleaner and safer working environment.

[0031] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0032] like Figure 1-5 As shown, the present invention provides a coal mine electromechanical conveying device, such as... Figure 1-2 As shown, the system includes a vehicle body 1, a coal shoveling assembly 2, and a coal pressing assembly 3. The upper part of the vehicle body 1 is open, and the coal shoveling assembly 2 is located at the front of the vehicle body 1. It is used to shovel coal and transport it through the upper part of the vehicle body 1 into its interior. This structure can replace manual filling operations, significantly reducing the workload of workers and effectively improving the overall operating efficiency of the equipment.

[0033] The coal shoveling assembly 2 includes a bucket 21 and a shovel 22. The bucket 21 is hinged to the vehicle body 1 via a first telescopic arm 4, which can drive the bucket 21 to tilt up and down, allowing for flexible adjustment of the shoveling angle. A second telescopic arm 5 is also provided between the bucket 21 and the vehicle body 1, which can drive the bucket 21 to move back and forth, facilitating the smooth shoveling of coal onto the bucket 21. The shovel 22 is hinged to the front end of the bucket 21, allowing the shovel 22 to swing upward relative to the bucket 21, thereby effectively hooking coal and preventing it from slipping.

[0034] Preferably, the bucket 21 and the vehicle body 1 adopt a detachable hinge structure, which facilitates subsequent maintenance or replacement of damaged bucket 21, and improves the ease of maintenance and service life of the lifting device.

[0035] It should be noted that when the first telescopic boom 4 extends to its maximum stroke, the bucket 21 flips to its maximum angle position. This position does not interfere with the coal pressing component 3, ensuring the coordinated operation of the various functional components.

[0036] Among them, such as Figure 1 , Figure 3-5 As shown, the coal compaction assembly 3 includes a support member 31 and a lower compactor 32. The support member 31 spans horizontally across the side plates 11 on both sides of the vehicle body 1. Each side plate 11 has a slide rail 12 extending horizontally in the front-to-back direction on its outer side. Multiple pulleys 33 are provided on the lower sides of both sides of the support member 31, and these pulleys 33 slide and engage with the slide rail 12 on their respective sides, allowing the support member 31 to be supported above the vehicle body 1 and to slide back and forth along the slide rail 12. This adapts to the compaction requirements at different locations. The support member 31 and the lower compactor 32 are movably connected, allowing the lower compactor 32 to move vertically relative to the support member 31. Furthermore, the coal compaction assembly 3 is designed to be manually movable and vertically adjustable within the vehicle body 1, allowing the lower compactor 32 to switch between a clearance state and a working state.

[0037] When the lower pressing component 32 is in the avoidance state, the lower pressing component 32 is located on the upper rear side of the vehicle body 1, and the coal shoveling assembly 2 can smoothly transport coal from the upper front side of the vehicle body 1 to the interior of the vehicle body 1 without interfering with each other.

[0038] When the lower pressing component 32 is in working condition, it can move along the front and rear direction and move up and down along the vehicle body 1 to compact the coal inside the vehicle body 1, effectively compress the coal stacking volume, increase the loading capacity of a single transport, and thus improve transport efficiency.

[0039] Locking blocks 34 are also provided on the left and right sides of the support member 31. The locking blocks 34 are C-shaped. The support member 31 includes a first plate 311 and a second plate 312 that are spaced apart vertically. The first plate 311 and the second plate 312 form an installation space that is adapted to the locking blocks 34. The locking blocks 34 have inward openings and their upper ends are inserted into the installation space and fixedly connected to the second plate 312. The lower ends of the locking blocks 34 abut against the bottom of the slide rail 12. The locking blocks 34 can slide back and forth along the slide rail 12 with the support member 31.

[0040] Manually move the pressing component 32 or the support component 31 to move the pulley 33 inside the slide rail 12, thereby moving the coal pressing assembly 3. This facilitates the pressing of the loosely piled coal inside the car body 1. After the operation is completed, the lower end of the locking block 34 is fixedly connected to the bottom of the slide rail 12 in a detachable manner (such as by bolts) to ensure the stability of the coal pressing assembly 3 and keep the pressing component 32 in a non-collision state. In use, release the connection between the lower end of the locking block 34 and the bottom of the slide rail 12 to restore the free displacement of the coal pressing assembly 3. The position of the pressing component 32 can be flexibly adjusted according to the operation requirements to facilitate subsequent pressing of the coal transported inside the car body 1, compressing the coal's stockpile volume, loading more coal, and improving transportation efficiency.

[0041] Multiple first hydraulic cylinders 35 are installed in the support member 31. The fixed end of the first hydraulic cylinder 35 is fixedly connected to the support member 31, and the telescopic end of the first hydraulic cylinder 35 passes downward through the support member 31 and is fixedly connected to the pressing member 32. The first hydraulic cylinder 35 can drive the pressing member 32 to move up and down, which facilitates the mechanical compression of coal.

[0042] like Figure 2 As shown, a movable door 13 is provided at the rear end of the vehicle body 1 for opening and closing the rear end of the vehicle body 1, which facilitates unloading operations.

[0043] like Figure 1 , Figure 3-5 As shown, scrapers 36 are provided at both the front and rear ends of the pressing member 32. The pressing member 32 is a U-shaped component with a flat plate 321. A vertically extending groove 323 is provided on the outer side of the side plate 322 of the pressing member 32. The scrapers 36 are steel components with an L-shaped cross-section. The openings of the two scrapers 36 are arranged opposite each other. A slider 37 that slides in cooperation with the groove 323 is provided on the inner side of the vertical plate 361 of the scraper 36. The two scrapers 36 can move up and down independently relative to the pressing member 32, and the scrapers 36 can move along the front and rear direction of the vehicle body 1 with the pressing member 32.

[0044] During unloading, the movable door 13 opens, and the scraper 36 located in front can descend relative to the lowering member 32 and move towards the rear of the car body 1 with the lowering member 32 to assist in pushing the coal out from the rear end of the car body 1.

[0045] like Figure 2As shown, the lower edge of the movable door 13 is hinged to the bottom plate 14 of the vehicle body 1. A third telescopic arm 6 is also provided between the movable door 13 and the vehicle body 1. The third telescopic arm 6 can drive the movable door 13 to rotate around the lower edge of the movable door 13 to open and close the movable door 13. By controlling the opening and closing of the movable door 13, it is convenient for workers to efficiently unload coal from the vehicle body 1 after transporting the coal to the designated location.

[0046] like Figure 1 , Figure 3-5 As shown, a second hydraulic cylinder 38 is provided on the outer side of each of the two side plates 322. The fixed end of the second hydraulic cylinder 38 is fixedly connected to the side plate 322 on the corresponding side, and the telescopic end of the second hydraulic cylinder 38 is fixedly connected to the horizontal plate 362 of the scraper 36 on the corresponding side. The second hydraulic cylinder 38 can drive the scraper 36 on the corresponding side to move up and down relative to the lower pressing member 32. When the second hydraulic cylinder 38 extends to its maximum stroke, the bottom wall of the horizontal plate 362 is flush with the bottom wall of the pressure plate 321. When the bottom walls of the horizontal plates 362 of both scrapers 36 are flush with the bottom wall of the pressure plate 321, the two horizontal plates 362 and the pressure plate 321 together form a larger pressing area, thereby further improving the compaction efficiency.

[0047] A limiting plate 39 is provided at the top of the slider 37. The limiting plate 39 can be locked onto the upper end of the side plate 322 to prevent the scraper 36 from coming off during the lifting process and improve operational safety.

[0048] like Figure 1-2 As shown, tracks 7 are installed on both sides of the bottom of the vehicle body 1. The tracks 7 are connected to a power source (not shown in the figure) to facilitate the movement of the transport device, thereby meeting the mobility requirements of coal transportation.

[0049] It should be noted that the communication connection of the transport device is powered to ensure the normal operation of all components in the transport device.

[0050] In addition, the surfaces of the vehicle body 1, the coal shoveling assembly 2, and the coal pressing assembly 3 are all coated with anti-corrosion paint, which can effectively prevent the surfaces of the vehicle body 1, the coal shoveling assembly 2, and the coal pressing assembly 3 from being eroded by oxidation, corrosion, and other environmental factors, thus extending the service life of the vehicle body 1, the coal shoveling assembly 2, and the coal pressing assembly 3.

[0051] The coal shovel assembly 2 is made of wear-resistant metal with high surface hardness and good wear resistance to significantly reduce wear caused by coal friction, extend the service life of the coal shovel assembly 2, and reduce maintenance costs.
