Description

Technical Field

[0001] This application generally relates to the field of underground engineering, and specifically to a device for cleaning sludge at the bottom of a vertical conveyor belt in a shaft. Background Technology

[0002] Currently, the number of construction tunnels in my country using vertical conveyor belts for transporting excavated soil is increasing daily. Domestic and international experts and scholars have conducted extensive research in the field of vertical conveyor belt construction technology. By establishing numerical models, they have analyzed the working modes of vertical conveyor belts under different working conditions, effectively solving many problems such as ultra-deep shafts, confined spaces, and simultaneous construction of multiple tasks, and providing solid technical support for construction applications. However, research on how to quickly clean up excavated soil falling from vertical conveyor belts in confined spaces is relatively scarce, especially when vertical conveyor belts are located in environments with well-developed fissure water in rock strata. Excavated soil falling during the lifting process combines with water to form silt. If not cleaned in time, this will not only damage the vertical conveyor belt but also affect its service life and operational stability.

[0003] In recent years, to address the issue of cleaning up debris falling from vertical conveyor belts in shafts, most construction scenarios have employed traditional methods such as manual cleaning and crane lifting. However, using traditional manual cleaning methods while the vertical conveyor belt is in operation poses significant safety hazards, while stopping the machine to use a crane for cleaning would severely impact the construction progress. In some scenarios, a pre-formed slag hopper is placed under the vertical conveyor belt to catch the falling debris, and then replaced when full. This method requires a large enough space and convenient lifting conditions at the construction site, making it difficult to apply in ultra-deep shafts or scenarios where multiple work faces are operating simultaneously.

[0004] Therefore, in order to quickly clean the sludge at the bottom of a vertical conveyor belt in a limited space, this application provides a sludge cleaning device for the bottom of a vertical conveyor belt in a vertical shaft. Utility Model Content

[0027] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] This application provides a device for cleaning sludge at the bottom of a vertical conveyor belt in a shaft, comprising:

[0030] The gripping mechanism 1 is movable along a first direction and includes a gripping device 2 for gripping silt at the bottom of the vertical conveyor belt in the shaft; the first direction is the conveying direction of the vertical lifting section of the vertical conveyor belt in the shaft.

[0031] Lifting mechanism 3 is connected to gripping mechanism 1 and is used to drive gripping mechanism 1 to move up and down and to drive gripping device 2 to switch between gripping and releasing states.

[0032] The walking mechanism 4 is connected to the lifting mechanism 3 and is used to drive the lifting mechanism 3 to move the gripping mechanism 1 along a second direction; the second direction is perpendicular to the first direction.

[0033] The slag transfer mechanism 5 is set at the unloading position corresponding to the grabbing mechanism 1. It is located in the horizontal receiving section of the vertical conveyor belt of the shaft and is used to guide the sludge released by the grabbing device 2 and transport the sludge to the outside of the shaft through the vertical lifting section of the vertical conveyor belt of the shaft.

[0034] It should be noted that the sludge cleaning device at the bottom of the vertical conveyor belt in this application includes a grabbing mechanism 1, a lifting mechanism 3, a traveling mechanism 4, and a slag transfer mechanism 5. When cleaning the sludge at the bottom of the vertical conveyor belt, the grabbing mechanism 1 is moved above the area to be cleaned by the traveling mechanism 4. Then, the lifting mechanism 3 drives the grabbing mechanism 1 to descend to the bottom of the shaft. During this process, the grabbing device 2 opens under the drive of the lifting mechanism 3 and enters the grabbing state. After the grabbing device 2 is fully extended, the lifting mechanism 3 drives it to close, thereby completing the grabbing of the bottom sludge and driving the grabbing mechanism 1 and the grabbed sludge to rise to a designated height. After the grabbing is completed, the traveling mechanism 4 drives the lifting mechanism 3 to move in the second direction, thereby transporting the grabbing mechanism 1 to the top of the slag transfer mechanism 5. At this time, the lifting mechanism 3 controls the grabbing device 2 to switch to the release state and unloads the sludge into the slag transfer mechanism 5. The slag transfer mechanism 5 guides the received sludge to the horizontal receiving section of the vertical conveyor belt, and finally the vertical lifting section of the vertical conveyor belt transports the sludge to the outside of the shaft. The grabbing mechanism 1 can move along a first direction (the vertical lifting section of the vertical belt conveyor in the shaft), enabling it to grab the bottom sludge and transport it to the slag transfer mechanism 5. It can also handle uneven distribution of the bottom sludge. The grabbing device 2 installed on the grabbing mechanism 1 can grab the sludge and serve as a transport carrier. The lifting mechanism 3 drives the grabbing mechanism 1 to move up and down, ensuring that the grabbing device 2 can contact the bottom sludge and be lifted to the unloading height. It also switches the grabbing device 2 between grabbing and releasing states. The traveling mechanism 4 drives the lifting mechanism 3 along a second direction (the second direction...). The device moves in the direction of the horizontal receiving section of the vertical conveyor belt in the shaft, thereby driving the grabbing mechanism 1 to move, expanding the cleaning range at the bottom of the vertical conveyor belt. Simultaneously, after grabbing the sludge, the grabbing device 2 can be driven by the walking mechanism 4 to transport the sludge to the slag transfer mechanism 5. The slag transfer mechanism 5 is set at the unloading position of the grabbing mechanism 1, and can receive the sludge released by the grabbing device 2, guiding the sludge to the horizontal receiving section of the vertical conveyor belt in the shaft, avoiding sludge scattering and causing secondary pollution. Finally, the sludge is transported to the outside of the shaft by the lifting section of the vertical conveyor belt, ensuring the continuity and efficiency of the entire cleaning process. This device achieves rapid and efficient cleaning of the sludge at the bottom of the vertical conveyor belt in a limited space through the coordinated cooperation of various mechanisms, ensuring the normal operation of the vertical conveyor belt. It is understood that when the lifting mechanism 3 drives the grabbing mechanism 1 to descend, the grabbing device 2 can open simultaneously, for example, as... Figure 4As shown, the lifting mechanism 3 can be two electric hoists, which are respectively connected to the gripping mechanism 1 and the gripping device 2. When the first electric hoist 15 drives the gripping mechanism 1 to descend, the gripping device 2 needs to follow. During this process, the second electric hoist 18 will drive the gripping device 2 to open synchronously. Of course, when the lifting mechanism 3 drives the gripping mechanism 1 to descend, the gripping device 2 can open asynchronously. For example, the lifting mechanism 3 is a separate electric hoist that controls the lifting and lowering of the gripping mechanism 1. When the gripping mechanism 1 descends to the top of the bottom silt, the opening and closing of the gripping device 2 can be controlled by a separate cylinder.

[0035] Furthermore, the gripping mechanism 1 includes a first connecting beam 6, a second connecting beam 7, a connecting rod 8, and a gripping device 2. The first connecting beam 6 is connected to the lifting mechanism 3. The second connecting beam 7 is rotatably connected to the gripping device 2 through a rotating shaft 9 that passes through the second connecting beam 7. The two ends of the connecting rod 8 are hinged to the first connecting beam 6 and the gripping device 2, respectively.

[0036] It should be noted that the first connecting beam 6 has symmetrical connecting parts at both ends. For example, the connecting parts can be set as ear plates or lifting rings. The lifting mechanism 3 is connected to the gripping mechanism 1 as a whole through the connecting parts to ensure that the gripping mechanism 1 can stably follow the movement when the lifting mechanism 3 drives the gripping mechanism 1 to rise and fall. The second connecting beam 7 is rotatably connected to the gripping device 2 through a rotating shaft 9 that passes through the second connecting beam 7. The direction of the rotating axis is parallel to the first direction. The rotating shaft 9 is fixedly connected to the second connecting beam 7, so that the gripping device 2 can rotate around the rotating shaft 9 to achieve opening and closing. There are two sets of connecting rods 8 arranged symmetrically, and their two ends are respectively hinged to the first connecting beam 6 and the gripping device 2. When the lifting mechanism 3 moves the gripping mechanism 1 downwards via the first connecting beam 6, it also moves the second connecting beam 7 downwards, increasing the distance between the first and second connecting beams. At this time, the gripping device 2 pushes two sets of symmetrically arranged connecting rods 8 to rotate around their hinge points with the first connecting beam 6, thus opening the gripping device 2. Similarly, when the lifting mechanism 3 moves the gripping mechanism 1 upwards via the first connecting beam 6, it moves the second connecting beam 7 upwards, decreasing the distance between the first and second connecting beams. At this time, the gripping device 2 pulls the two sets of symmetrically arranged connecting rods 8 to rotate around their hinge points with the first connecting beam 6, thus closing the gripping device 2 and completing the gripping of silt. Through the coordinated operation of multiple components, the opening and closing of the gripping device 2 is achieved simultaneously during the upward or downward movement of the gripping mechanism 1, further improving the working efficiency of the gripping mechanism 1.

[0037] Furthermore, the gripping device 2 adopts a symmetrical double-lobed structure, including a first lobe 10 and a second lobe 11. One end of the first lobe 10 and the second lobe 11 are respectively hinged to the connecting rod 8, and the other end of the first lobe 10 and the second lobe 11 are jointly hinged to the rotating shaft 9. By adjusting the distance between the first connecting beam 6 and the second connecting beam 7, the first lobe 10 and the second lobe 11 can be driven to rotate around the rotating shaft 9 to achieve opening and closing.

[0038] It should be noted that the grabbing device 2 adopts a double-lobed structure design, with the first lobe 10 and the second lobe 11 symmetrically arranged and hinged to the connecting rod 8 through independent hinge points. At the same time, the symmetrically arranged connecting rod 8 makes the force on the first lobe 10 and the second lobe 11 more balanced. When the lifting mechanism 3 drives the second connecting beam 7 to move along the first direction and adjusts the distance between the first connecting beam 6 and the second connecting beam 7, the first lobe 10 and the second lobe 11 can rotate around the rotating shaft 9. Through the transmission action of the connecting rod 8, the first lobe 10 and the second lobe 11 will pull or push the two sets of symmetrically arranged connecting rods 8 respectively, realizing the opening and closing of the grab bucket to complete the grabbing and release of silt.

[0039] Furthermore, the first connecting beam 6 is also provided with a mounting base 12, and the mounting base 12 is provided with a first pulley 13 inside.

[0040] It should be noted that the mounting base 12 on the first connecting beam 6 provides a mounting carrier for the first pulley 13, and the first pulley 13 is a fixed pulley that has a guiding function, for example, as... Figure 3 As shown, the lifting mechanism 3 includes a second drive assembly 17, which includes a second electric hoist 18 and a second traction rope 19. A second pulley 20 is provided inside the second connecting beam 7. One end of the second traction rope 19 is fixedly connected to the mounting base 12 and passes around the second pulley 20, is guided by the first pulley 13, and is then connected to the second electric hoist 18. The first pulley 13 can be used to guide the second traction rope 19 that connects the lifting mechanism 3 and the gripping mechanism 1.

[0041] Furthermore, the lifting mechanism 3 includes a first drive assembly 14, which includes a first electric hoist 15 and a first traction rope 16. One end of the first traction rope 16 is connected to the first electric hoist 15, and the other end is fixedly connected to the first connecting beam 6.

[0042] It should be noted that the lifting mechanism 3 includes a first drive assembly 14 and a second drive assembly 17, which respectively control the movement of the gripping mechanism 1 and the opening and closing of the gripping device 2. In the first drive assembly 14, the first electric hoist 15 can drive the first traction rope 16 to be wound up and down, thereby realizing the lifting and lowering control of the gripping mechanism 1 by wounding and lowering the first traction rope 16. The first traction rope 16 can be a set of steel wire ropes, one end of which is connected to the first electric hoist 15, and the other end is fixed to the connecting part of the first connecting beam 6, for example, the connecting part can be a lifting ring. Under the drive of the first electric hoist 15, the first connecting beam 6 can be moved along the first direction, thereby driving the entire gripping mechanism 1 to rise or fall. The lifting and lowering height of the gripping mechanism 1 can be adjusted to meet the working needs of vertical shafts of different depths.

[0043] Furthermore, the lifting mechanism 3 also includes a second drive assembly 17, which includes a second electric hoist 18 and a second traction rope 19. A second pulley 20 is provided inside the second connecting beam 7. One end of the second traction rope 19 is fixedly connected to the mounting base 12 and passes around the second pulley 20, is guided by the first pulley 13, and is then connected to the second electric hoist 18. The second electric hoist 18 changes the distance between the second pulley 20 and the first pulley 13 by the traction of the second traction rope 19.

[0044] It should be noted that the second drive assembly 17 includes a second electric hoist 18 and a second traction rope 19. The second traction rope 19 can be a set of steel wire ropes. One end of the steel wire rope is connected to the second electric hoist 18, and the other end is wound around the second pulley 20 (the second pulley 20 is a movable pulley) and continuously wound around the first pulley 13 multiple times before being fixedly connected to the mounting base 12 of the first connecting beam 6. As the number of winding turns increases, the second electric hoist 18 drives the gripping device 2 to open and close more smoothly through the second traction rope 19, and at the same time, the process of changing the distance between the second pulley 20 and the first pulley 13 is smoother. When the second traction rope 19 is retracted or extended, the distance between the second pulley 20 and the first pulley 13 changes, and the second connecting beam 7 moves relative to the first connecting beam 6 in the first direction, which can realize the adjustment of the opening and closing of the gripping device 2 and improve the controllability of the gripping action. It can be understood that by changing the distance between the second connecting beam 7 and the first connecting beam 6, the opening and closing angle of the gripping device 2 can be controlled to adapt to the gripping needs of different working conditions.

[0045] Furthermore, the walking mechanism 4 includes a support frame 21 and a load-bearing beam 22. The support frame 21 is disposed at the bottom of the load-bearing beam 22 along the first direction and is fixedly connected to the load-bearing beam 22 to provide support for the load-bearing beam 22.

[0046] It should be noted that, as Figure 1As shown, the load-bearing beam 22 adopts an I-shaped structure. The load-bearing beam 22 provides space for the installation of other driving components of the walking mechanism 4. The bottom two sides are provided with inverted V-shaped support frames 21. The support frames 21 are arranged along the first direction and fixedly connected to the load-bearing beam 22, which can form a stable support for the load-bearing beam 22, ensuring that the load-bearing beam 22 remains structurally stable when the load-bearing lifting mechanism 3 drives the gripping mechanism 1 to move along the second direction, and avoiding tilting or shaking due to uneven force.

[0047] Furthermore, the walking mechanism 4 also includes a walking motor 23, which can move along the bearing beam 22. The lifting mechanism 3 is fixedly connected to the walking motor 23. When the walking motor 23 moves along the bearing beam 22, it drives the lifting mechanism 3 to move, which in turn drives the gripping mechanism 1 to move synchronously.

[0048] It should be noted that the supporting beam 22 is equipped with a track, and there can be multiple walking motors 23. Each walking motor 23 is equipped with a walking wheel. The walking motor 23 can move along the track of the supporting beam 22 through the walking wheel. The walking motor 23 provides a power source for the gripping mechanism 1 to move in the second direction, ensuring that the gripping mechanism 1 can move to the area to be cleaned or above the slag transfer mechanism 5.

[0049] Furthermore, each of the first and second petals 10 and 11 is provided with a set of ear plates 24, and the ear plates 24 are also provided with limiting blocks 25; when the first and second petals 10 and 11 unfold to the sides, they drive the ear plates 24 to rotate, thereby causing the limiting blocks 25 to approach each other until they collide.

[0050] It should be noted that when the first petal 10 and the second petal 11 unfold to the sides, the ear plate 24 rotates synchronously, causing the limiting block 25 to gradually approach and eventually collide, thus limiting the maximum unfolding angle of the first petal 10 and the second petal 11.

[0051] Furthermore, the slag transfer mechanism 5 includes a receiving hopper 26 and a guide channel 27. The receiving hopper 26 is connected to the guide channel 27 and is used to guide the sludge released by the grabbing device 2 to the horizontal receiving section of the vertical conveyor belt in the shaft.

[0052] It should be noted that the structural design of the slag transfer mechanism 5, which connects the receiving hopper 26 with the guide channel 27, can form a continuous sludge conveying channel, such as... Figure 2 As shown, the width of the receiving hopper 26 is greater than the maximum opening angle of the grabbing device 2, ensuring that all the sludge released by the grabbing device 2 can fall into the slag transfer mechanism 5, avoiding sludge scattering and causing secondary pollution; while the guide channel 27 guides the sludge received by the receiving hopper 26 to the horizontal receiving section of the vertical conveyor belt in the shaft, avoiding the accumulation of sludge during the transfer process, and further improving the working efficiency and reliability of the entire cleaning device.

[0053] Working Principle: When cleaning the sludge at the bottom of the vertical conveyor belt in the shaft, firstly, the traveling motor 23 moves along the track on the bearing beam 22, driving the lifting mechanism 3 and the grabbing mechanism 1 to move in the second direction. After positioning to the area to be cleaned, the first electric hoist 15 releases the first traction rope 16, driving the grabbing mechanism 1 to descend, bringing the grabbing device 2 closer to the sludge. During the descent of the grabbing device 2, simultaneously, the second electric hoist 18 releases the second traction rope 19, increasing the distance between the first connecting beam 6 and the second connecting beam 7 of the grabbing mechanism 1. The grabbing device 2 pulls the two sets of connecting rods 8, causing the first bucket 10 and the second bucket 11 to rotate around the rotating shaft 9, thereby opening the grabbing device 2. Subsequently, the second electric hoist 18 rewinds the second traction rope 19, reducing the distance between the first pulley 13 and the second pulley 20, and further reducing the distance between the first connecting beam 6 and the second connecting beam 7. The two sets of connecting rods 8 then push the first bucket 10 and the second bucket 11 to rotate around the rotating shaft 9, achieving sludge grabbing and closure. After the grabbing is completed, the first electric hoist 15 winds up the first traction rope 16 to lift the grabbing mechanism 1. The traveling motor 23 drives the lifting mechanism 3 and the grabbing mechanism 1 to move above the slag transfer mechanism 5. The second electric hoist 18 releases the second traction rope 19 to open the grabbing device 2 and release the sludge. After the sludge falls into the receiving hopper 26, it enters the horizontal receiving section of the vertical conveyor belt in the shaft through the guide channel 27, and is finally sent out of the shaft by the vertical lifting section of the vertical conveyor belt. This device achieves positioning through the coordinated action of various mechanisms: the traveling mechanism 4 achieves positioning and drives the lifting mechanism 3 to move. The lifting mechanism 3 controls the lifting and opening / closing of the grabbing device 2. After the grabbing device 2 grabs the sludge, the traveling mechanism 4 drives the grabbing mechanism 1 to move above the slag transfer mechanism 5. The slag transfer mechanism 5 guides the sludge to the horizontal receiving section of the vertical conveyor belt in the shaft, and finally sends it out of the shaft by the vertical lifting section of the vertical conveyor belt. The entire process avoids the safety hazards associated with traditional manual cleaning. It enables continuous transport of sludge within a limited space via a vertical conveyor belt in the shaft, eliminating the need for other devices to transfer the sludge outside the shaft. This reduces the impact of sludge accumulation on the operation of the vertical conveyor belt and ensures the continuity and efficiency of the entire cleaning process.
