Description

Technical Field

[0001] This invention relates to the field of bridge structure technology, specifically to a coal trough and a belt conveyor trestle. Background Technology

[0002] A belt conveyor trestle is a bridge-type structure for mechanically transporting materials, consisting of a conveyor on top and a supporting frame below. Belt conveyor trestles are mostly used in harsh working environments such as coal-fired power plants and coal cargo terminals. Therefore, during coal unloading and transfer, belt conveyor trestles generate a large amount of coal dust, which easily accumulates at the bottom of the conveyor and impacts the surrounding environment. To solve this technical problem, existing belt conveyor trestles generally have a washing device suitable for flushing the coal dust at the bottom of the conveyor. A water receiving trough is installed below the conveyor, allowing the molten coal generated by automatic washing to be discharged into a coal slurry pool, thus enabling the reuse of coal slime.

[0003] With the increasing use of conveyors for long-distance bulk material transportation, belt conveyor systems ranging from tens of kilometers in length are applied across various industries. Installing a water collection trough beneath long-distance conveyors significantly enhances the reuse of coal slime, minimizing resource waste. However, conveyors longer than 120 meters require temperature expansion joints, and these joints necessitate water collection troughs. These joints are prone to displacement due to thermal expansion and contraction, and existing technologies struggle to reliably connect the water collection troughs to the temperature expansion joints of long-distance conveyors. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the coal water tank is difficult to reliably connect with the temperature deformation joint of the long-distance conveyor in the prior art, thereby providing a coal water tank and belt conveyor trestle that can reliably connect with the temperature deformation joint of the long-distance conveyor.

[0005] To address the aforementioned problems, the first aspect of the present invention provides a coal-water trough, comprising: a first trough body and a second trough body, adapted to be disposed below a conveyor, the two ends of the first trough body and the second trough body being adapted to be fixedly connected to the lower part of the conveyor respectively; a flexible connector located below the temperature deformation joint of the conveyor, the two ends of the flexible connector being fixedly connected to the first trough body and the second trough body respectively, and adapted to seal the gap between the first trough body and the second trough body; and a guide channel disposed within the first trough body and the second trough body, covering the flexible connector, the guide channel being slidably connected to the first trough body and / or the second trough body, the sliding direction of the guide channel being parallel to the length direction of the first trough body.

[0006] Furthermore, a first connecting hole and a second connecting hole are respectively formed on the side walls of the first water tank body and the guide channel, allowing fasteners to pass through in sequence. The first connecting hole and / or the second connecting hole are strip-shaped holes extending along the length direction of the first water tank body.

[0007] The second water tank body and the guide channel sidewalls are respectively formed with a third connecting hole and a fourth connecting hole, which allow fasteners to pass through in sequence. The third connecting hole and / or the fourth connecting hole are strip-shaped holes extending along the length direction of the second water tank body.

[0008] Furthermore, the top of the side wall of the first water tank body is formed with an outwardly bent first abutting flange, the top of the side wall of the guide channel is formed with a first mating flange suitable for abutting against the first abutting flange, a first connecting hole is formed on the first abutting flange, and a second connecting hole is formed on the first mating flange.

[0009] The top of the side wall of the second water tank body has a second outwardly bent abutting edge, the top of the side wall of the guide channel has a second mating edge adapted to abut against the second abutting edge, a third connecting hole is formed on the second abutting edge, and a fourth connecting hole is formed on the second mating edge.

[0010] Furthermore, the flexible connector is a corrugated joint, and the expansion and contraction direction of the corrugated joint is parallel to the length direction of the first water tank body.

[0011] Furthermore, the coal water tank also includes a first sealing strip and a second sealing strip. The first sealing strip is suitable for sealing the gap between one side of the corrugated section and the main body of the first water tank, and the second sealing strip is suitable for sealing the gap between the other side of the corrugated section and the main body of the second water tank.

[0012] Furthermore, one side of the corrugated joint is welded to the main body of the first water tank, and the other side of the corrugated joint is welded to the main body of the second water tank.

[0013] Furthermore, the two ends of the first and second water tank bodies are adapted to be welded to the lower crossbeam of the conveyor, respectively.

[0014] The second aspect of the present invention relates to a belt conveyor bridge, comprising:

[0015] Support structure;

[0016] The conveyor is mounted on the supporting structure;

[0017] As described in the first aspect of the present invention, the coal-water trough is disposed below the conveyor.

[0018] The present invention has the following advantages:

[0019] As can be seen from the above technical solution, in the coal-water trough of the first aspect of the present invention, the first trough body and the second trough body are respectively fixedly connected to the lower part of the conveyor. The flexible connector can provide a soft connection between the first trough body and the second trough body, playing a role in shock absorption and releasing the temperature stress generated by the thermal expansion and contraction of the conveyor. The guide channel covers the flexible connector and is slidably connected to the first trough body and / or the second trough body, which can prevent leakage between the flexible structure and the first trough body and the second trough body, thus avoiding pollution to the environment caused by leakage. Therefore, the coal-water trough of the first aspect of the present invention can overcome the defect of the prior art that it is difficult to reliably connect the coal-water trough to the temperature deformation joint of the long-distance conveyor. In addition, the coal-water trough of the present invention has a simple structure and is easy to apply.

[0020] 2. The belt conveyor trestle of the second aspect of the present invention includes or uses the coal water trough of the first aspect of the present invention. Therefore, the belt conveyor trestle of the second aspect of the present invention also has the beneficial effects of the coal water trough of the first aspect of the present invention, that is, it can overcome the defect that the coal water trough in the prior art is difficult to reliably connect with the temperature deformation joint of the long-distance conveyor. In addition, the coal water trough of the present invention has a simple structure and is easy to apply. Attached Figure Description

[0036] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0037] Example 1

[0038] Figure 1 The coal-water tank of Embodiment 1 of the present invention is shown in use. Figure 2 This is a side view of the coal-water trough according to Embodiment 1 of the present invention. Figure 1 and Figure 2 As shown, the coal-water trough in Embodiment 1 mainly includes a first trough body 1, a second trough body 2, a flexible connector 3, and a guide channel 4. The first trough body 1 and the second trough body 2 are adapted to be installed below a conveyor. Both ends of the first trough body 1 and the second trough body 2 are adapted to be fixedly connected to the lower part of the conveyor, respectively. The flexible connector 3 is located below the temperature deformation joint 201 of the conveyor. Both ends of the flexible connector 3 are fixedly connected to the first trough body 1 and the second trough body 2, respectively, and are adapted to seal the gap between the first trough body 1 and the second trough body 2. The conveyor is preferably, but not limited to, a belt conveyor.

[0039] The guide channel 4 is disposed inside the first water tank body 1 and the second water tank body 2 and covers the flexible connector 3. The guide channel 4 is slidably connected to the first water tank body 1 and / or the second water tank body 2. The sliding direction of the guide channel 4 is parallel to the length direction of the first water tank body 1.

[0040] As can be seen from the above technical solution, in the coal-water trough 100 of this embodiment 1, the first trough body 1 and the second trough body 2 are respectively fixedly connected to the lower part of the conveyor. The flexible connector 3 can provide a soft connection between the first trough body 1 and the second trough body 2, thereby playing a role in shock absorption and releasing the temperature stress generated by the thermal expansion and contraction of the conveyor. The guide channel 4 covers the flexible connector 3 and is slidably connected to the first trough body 1 and / or the second trough body 2, which can prevent leakage between the flexible structure and the first trough body 1 and the second trough body 2, and avoid pollution to the environment caused by leakage. Therefore, the coal-water trough 100 of this embodiment 1 can overcome the defect of the coal-water trough 100 in the prior art being difficult to reliably connect with the temperature deformation joint 201 of the long-distance conveyor. In addition, the coal-water trough 100 of this embodiment 1 has a simple structure and is easy to apply.

[0041] The sidewalls of the first water tank body 1 and the guide channel can be slidably connected by a slide rail, or slidably connected by the cooperation of a guide protrusion and a guide groove. Preferably, in this embodiment, the sidewalls of the first water tank body 1 and the guide channel 4 are respectively formed with a first connecting hole 11 and a second connecting hole 41 that allow fasteners to pass through sequentially. The first connecting hole 11 and / or the second connecting hole 41 are strip-shaped holes extending along the length direction of the first water tank body 1. When the conveyor moves due to thermal expansion and contraction, the fasteners can slide along the strip-shaped holes, ensuring that the first water tank body 1 and the guide channel are tightly fitted.

[0042] The sidewalls of the second water tank body 2 and the guide channel can be slidably connected by a slide rail, or slidably connected by a guide protrusion and a guide groove. Preferably, in this embodiment, the sidewalls of the second water tank body 2 and the guide channel 4 are respectively formed with a third connecting hole 21 and a fourth connecting hole 42, allowing fasteners to pass through sequentially. The third connecting hole 21 and / or the fourth connecting hole 42 are strip-shaped holes extending along the length direction of the second water tank body 2. When the conveyor moves due to thermal expansion and contraction, the fasteners can slide along the strip-shaped holes, ensuring that the first water tank body 1 and the guide channel are tightly fitted.

[0043] Fasteners can be bolts, rivets, or connecting posts, etc. Preferably, in this embodiment, high-strength bolts are selected as fasteners, which can improve the reliability of the coal water tank 100.

[0044] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the first connecting hole 11 and the second connecting hole 41 can be optionally formed on the sidewalls of the first water tank body 1 and the guide channel 4, respectively. Preferably, in this embodiment, the top of the sidewall of the first water tank body 1 has an outwardly bent first abutting flange 12. The top of the sidewall of the guide channel 4 has a first mating flange 43 adapted to abut against the first abutting flange 12. The first connecting hole 11 is formed on the first abutting flange 12, and the second connecting hole 41 is formed on the first mating flange 43. By abutting against the first abutting flange 12 and the first mating flange 43, the space inside the coal water tank 100 will not be occupied, thus avoiding the risk of leakage of the coal water tank 100.

[0045] The third connecting hole 21 and the fourth connecting hole 42 can be optionally formed on the sidewalls of the second water tank body 2 and the guide channel 4, respectively. Preferably, in this embodiment, the top of the sidewall of the second water tank body 2 has an outwardly bent second abutting edge 22, and the top of the sidewall of the guide channel 4 has a second mating edge 44 adapted to abut against the second abutting edge 22. The third connecting hole 21 is formed on the second abutting edge 22. The fourth connecting hole 42 is formed on the second mating edge 44. By abutting against the second abutting edge 22 and the second mating edge 44, the space inside the coal water tank 100 is not occupied, thus avoiding the risk of leakage of the coal water tank 100.

[0046] The flexible connector 3 can be made of a flexible material such as rubber or silicone. Preferably, such as... Figure 8As shown, in this embodiment, to extend the service life of the flexible structure, the flexible connector 3 is a corrugated joint, and the expansion and contraction direction of the corrugated joint is parallel to the length direction of the first water tank body 1. Since the corrugated joint has relatively low stiffness, one side of the corrugated joint is preferably welded to the first water tank body 1, and the other side is welded to the second water tank body 2, preferably using C10 welding. This improves the overall stiffness of the coal-water tank 100 and achieves an effective connection between the corrugated joint and the first water tank body 1 and the second water tank body 2.

[0047] In this embodiment, in order to improve the sealing between the corrugated joint and the first water tank body 1 and the second water tank body 2, such as Figure 5 and Figure 7 As shown, the coal water tank 100 preferably also includes a first sealing strip 5 and a second sealing strip 6. The first sealing strip 5 is adapted to seal the gap between one side of the corrugated joint and the first tank body 1. The second sealing strip 6 is adapted to seal the gap between the other side of the corrugated joint and the second tank body 2. The first sealing strip 5 and the second sealing strip 6 are preferably, but not limited to, made of flexible materials such as rubber or silicone.

[0048] In this embodiment, in order to ensure that the first water tank body 1 and the second water tank body 2 can be reliably connected to the conveyor, the two ends of the first water tank body 1 and the second water tank body 2 are respectively welded to the lower crossbeam 202 of the conveyor, which can improve the overall rigidity of the coal water tank 100 and realize the effective connection between the water tank and the conveyor.

[0049] Example 2

[0050] Example 2 relates to a belt conveyor trestle, including a support structure, a conveyor, and a coal-water trough 100. The conveyor is mounted on the support structure. The coal-water trough 100 is the same as that described in Example 1 of this invention, and it is positioned below the conveyor. The two ends of the first trough body 1 and the second trough body 2 of the coal-water trough are adapted to be fixedly connected to the lower part of the conveyor, respectively. The support structure is preferably, but not limited to, a wooden trestle or a steel trestle.

[0051] The belt conveyor trestle of Embodiment 2 of the present invention includes or uses the coal water trough 100 of Embodiment 1. Therefore, it has the beneficial effects of the coal water trough 100 of Embodiment 1 of the present invention, that is, it can overcome the defect that the coal water trough 100 in the prior art is difficult to reliably connect with the temperature deformation joint 201 of the long-distance conveyor. In addition, the belt conveyor trestle of Embodiment 2 has a simple structure and is easy to promote and apply.

[0052] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
