Description

Technical Field

[0001] The present invention relates to the technical field of conveyors, and particularly to a vertical lifting corrugated side conveyor. Background Art

[0002] The corrugated side conveyor is a conveying device widely used for conveying bulk materials. In the construction operations of some tunnels and caves with a certain height difference, it is necessary to transport the mined sand and stones to the ground. Before the conveyor was widely used, tools were used for hoisting, and later belt conveyors were used for conveying. However, the belt conveyor requires a certain angle during conveying, resulting in a large amount of construction work. Later, the corrugated side conveyor can achieve large-angle conveying. With the development of the rubber process, the corrugated side conveyor can gradually reach a vertical installation close to 90 degrees.

[0003] The corrugated side conveyor is particularly widely used in construction sites such as subway tunnels and water diversion tunnels. Due to the development of construction sites such as stations and vertical shafts, their vertical depths are constantly changing. Sometimes the depth can reach nearly 100 meters. At this time, the vertical drop of the corrugated side conveyor belt needs to reach 70 meters. If a traditional large-angle conveyor is used, the project volume is too large. If a vertical conveyor is used, the motor needs to overcome the self-weight of the conveyor belt, the weight of the material, and the friction between the conveyor belt and the conveyor rollers. Due to the large self-weight of the conveyor belt, the friction between the conveyor belt and the conveyor rollers is large when the conveyor belt turns at the top. Chinese Patent Publication No.: CN106395261B discloses a vertical lifting corrugated side conveyor, which discloses a conveyor that can be vertically lifted at a certain height, and basically realizes the vertical lifting of materials such as sand and stones. However, when conveying a drop of more than 30 meters in height, due to the influence of the self-gravity of the belt and the gravity of the conveyed material, the load is large, and a motor with a large power is required to drive the belt to work, resulting in a large occupied installation space, and there will also be a phenomenon of burning out the motor, which brings great inconvenience during on-site installation, debugging and use. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art that the corrugated side conveyor is inconvenient for on-site installation in the case of large drops and the friction between the conveyor belt and the conveyor rollers is large, and to provide a vertical lifting corrugated side conveyor.

[0005] In order to achieve the above object, the embodiments of the present invention specifically adopt the following technical solutions: A vertical lifting corrugated side conveyor includes a truss body, on which a corrugated conveyor belt is provided. The truss body includes a bottom truss, and the tail of the bottom truss is provided with a lifting truss through a connecting device. The top of the lifting truss is provided with a discharging truss. An arc-shaped support frame for transitioning the turning of the corrugated conveyor belt is arranged between the lifting truss and the discharging truss. An adjusting device for adjusting the turning angle is arranged on the arc-shaped support frame. The adjusting device includes a plurality of turning rollers, and a belt supporting device for reducing the friction between the turning rollers and the corrugated conveyor belt is arranged on the turning rollers.

[0006] Further, the bottom truss is horizontally arranged, and a frame and a material cylinder for assisting in material dropping are arranged on the upper part of the bottom truss. A plurality of material receiving roller groups are arranged on the upper part of the bottom truss, and the material receiving roller groups are arranged below the material cylinder.

[0007] Further, the connecting device includes a positioning chute arranged at the bottom of the lifting truss. A connecting frame is arranged on the side of the bottom truss. One end of the connecting frame is slidably arranged inside the positioning groove, and an adjusting hole connected to the connecting frame is arranged inside the positioning chute.

[0008] Further, a belt pressing device for adjusting the upward conveying angle of the corrugated conveyor belt is arranged at the bottom of the lifting truss. The belt pressing device includes a belt pressing shaft horizontally arranged on the lifting truss. Two belt pressing wheels are arranged on both sides of the belt pressing shaft, and the belt pressing wheels are pressed against both side edges of the corrugated conveyor belt.

[0009] Further, a baffle for preventing the corrugated conveyor belt from running off is arranged on the side of the belt pressing wheel.

[0010] Further, a plurality of maintenance platforms are arranged at intervals along the height direction on the side of the lifting truss. A blocking device for preventing the corrugated conveyor belt from retreating is arranged on the feeding side of the lifting truss.

[0011] Further, the blocking device includes a supporting wheel arranged below the corrugated conveyor belt. A follower wheel is arranged above the corrugated conveyor belt. The follower wheel is abutted against the side edge of the corrugated conveyor belt through a support rod. A limiting rod is arranged on the rod body of the support rod, and a spring for pressing down the support rod is arranged on the upper part of the limiting rod.

[0012] Further, the adjusting device includes adjusting discs arranged on the arc-shaped support frame. Two adjusting discs are oppositely arranged on the arc-shaped support frame. Connecting seats are arranged at both ends of the turning roller, and a plurality of the connecting seats are hinged. An adjusting rod is arranged at the hinge joint between the connecting seats, and the adjusting rod is connected to the adjusting disc.

[0013] Further, the turning roller includes a support shaft disposed on the connecting seat. Both ends of the support shaft are provided with air distribution discs. The inner side surface of the air distribution disc is provided with a plurality of air distribution holes. The outer side of the air distribution disc is provided with quick connectors for connecting a gas supply device.

[0014] Further, the belt supporting device includes an air distribution cylinder disposed on the outer side surface of the turning roller. The surface of the air distribution cylinder is provided with a plurality of air outlet holes.

The belt pressing device includes a belt pressing shaft horizontally arranged on the lifting truss. Two belt pressing wheels are arranged on both sides of the belt pressing shaft. The belt pressing wheels are pressed against both side edges of the corrugated conveyor belt. By pressing down the belt pressing wheels to restrict the conveyor belt, the conveyor belt is caused to change the conveying direction, so as to ensure that the corrugated conveyor belt remains stable during the conveying process, and the vertical lifting of the corrugated conveyor belt can be realized, reducing the occupied space and reducing the earthwork operation volume.

[0016] Both ends of the support shaft are fixedly provided with air distribution discs. The inner side surface of the air distribution disc is provided with a plurality of air distribution holes. The surface of the air distribution cylinder is provided with a plurality of air outlet holes. The air outlet holes are distributed on the surface of the air distribution cylinder. The air outlet holes on the air distribution cylinder will eject fine air columns outward, so as to form a relatively thin air film between the air distribution cylinder and the corrugated conveyor belt. The air flow ejects from the air outlet holes to form an air cushion, further reducing the contact area and friction force between the corrugated conveyor belt and the turning roller, making the corrugated conveyor belt more labor-saving during operation, reducing the load of the driving motor, and cooperating with the follower wheels to prevent the conveyor belt from retreating, greatly improving the use effect of the conveyor.

[0032] The following describes the preferred embodiments of the present invention with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0033] Embodiment 1

[0034] See Figures 1 to 8 , the embodiment of the present invention discloses a vertical lifting corrugated side conveyor, which is particularly suitable for construction operations with large height differences such as subway tunnels and water diversion tunnels, and is used to efficiently and stably transport materials such as sand and gravel generated during the tunneling process of a shield machine. The materials are lifted to the ground through the conveyor in this technical solution.

[0035] It mainly consists of a fixedly arranged truss body and a corrugated conveyor belt 202 arranged on the truss body. The corrugated conveyor belt 202 has its conveying capacity enhanced by the corrugated edges installed on both sides. The cross plates on the corrugated conveyor belt 202 lift the materials upward for conveying, reducing the spillage of materials and improving the conveying effect.

[0036] The truss body is divided into three parts: the bottom truss 1, the lifting truss 2, and the discharging truss 3. The bottom truss 1 is horizontally arranged and used to receive and initially carry materials. An upper part of the bottom truss 1 is provided with a frame and a material cylinder for assisting in material falling. A plurality of material receiving roller groups are arranged below the material cylinder to ensure that the materials can evenly and stably fall on the corrugated conveyor belt 202. The material receiving roller groups provide a stable supporting force to prevent excessive sagging of the corrugated conveyor belt 202 during the feeding process, ensuring the stable conveying of materials and improving the use effect. A turning roller is arranged at the end of the bottom truss 1, enabling the corrugated conveyor belt 202 to turn from below to above. The turning roller is connected to a motor through a speed reducer, and the motor is arranged at the bottom of the bottom truss 1, reducing the occupied space. Moreover, in order to prevent the corrugated conveyor belt 202 on the lower side from sagging, lower supporting rollers are arranged below the bottom truss 1 and below the discharging truss 3. The lower supporting rollers lift both ends of the corrugated conveyor belt 202, reducing the sagging and preventing the conveyor belt from jamming, improving the conveying effect.

[0037] The lifting truss 2 is connected to the tail of the bottom truss 1 and is used to lift the materials to the required height. The bottom truss 1 and the lifting truss 2 are connected through a connecting device. The connecting device includes a positioning chute arranged at the bottom of the lifting truss 2 and a connecting frame arranged on the side of the bottom truss 1. One end of the connecting frame is slidably arranged inside the positioning chute, and an adjustment hole connected to the connecting frame is arranged inside the positioning chute, so as to adjust the relative position between the bottom truss 1 and the lifting truss 2 as needed, adjust the angle between the horizontal and the vertical of the conveyor belt according to the on-site situation, reduce the stress generated during the conveying process and the installation process, and achieve the stable conveying of the corrugated conveyor belt 202, ensuring the stability during use. A belt pressing device 101 is arranged at the bottom of the lifting truss 2 and is used to adjust the upward conveying angle of the corrugated conveyor belt 202. The belt pressing device 101 includes a belt pressing shaft 102 horizontally arranged on the lifting truss 2. Two belt pressing wheels 103 are arranged on both sides of the belt pressing shaft 102. The belt pressing wheels 103 are pressed against both sides of the corrugated conveyor belt 202. By pressing down the belt pressing wheels 103 to limit the conveyor belt, the conveyor belt changes the conveying direction to ensure that the corrugated conveyor belt 202 remains stable during the conveying process. In order to prevent the corrugated conveyor belt 202 from running off track, a baffle 104 is arranged on the side of the belt pressing wheel 103. The diameter of the belt pressing wheel 103 is set relatively large, increasing the force-bearing area and reducing the extrusion force on the conveyor belt, ensuring the conveying effect.

[0038] The lifting truss 2 can be fixed on the side wall of the culvert through legs, or supported and fixed by a rack at the bottom, and auxiliary rods are installed in the height direction of the lifting truss 2 to provide support for the conveyor belt, ensuring the stability of the upward conveyance of the corrugated conveyor belt 202. A protective shell is provided outside the lifting truss 2 to reduce the splashing of sediment and sewage during conveyance and ensure the conveyance effect. A plurality of maintenance platforms 201 are arranged at intervals on the lifting truss 2, and one is installed at different heights, facilitating the maintenance and repair of different stages of the conveyor.

[0039] A blocking device is provided on the feeding side of the lifting truss 2 to prevent the corrugated conveyor belt 202 from retracting. The blocking device includes a support wheel 204 arranged below the corrugated conveyor belt 202 and a follower wheel 203 arranged above the corrugated conveyor belt 202. The follower wheel 203 abuts against the side of the corrugated conveyor belt 202 through a support rod 205. A one-way bearing is arranged at the axis position of the follower wheel 203, so that the follower wheel 203 can only rotate in one direction. The support rod 205 is hinged to a fixed rod arranged on the lifting truss 2. A limiting rod 206 is arranged on the rod body of the support rod 205, and a spring 207 is arranged on the upper part of the limiting rod 206 for pressing down the support rod 205, thereby maintaining the close contact between the follower wheel 203 and the corrugated conveyor belt 202. During use, the follower wheel 203 is pressed against the side of the conveyor belt, and two follower wheels 203 are respectively arranged on both sides of the conveyor belt to achieve the balance of the action. If the conveyor belt slips and retracts during conveyance, the follower wheel 203 will stop rotating and closely adhere to the conveyor belt under the pressing action of the spring 207. Since a plurality of follower wheels 203 are arranged at different positions and cooperate with each other, the protection effect is greatly improved, ensuring the use safety.

[0040] The discharging truss 3 is arranged at the top of the lifting truss 2 for unloading materials. Generally, the discharging truss 3 is horizontally arranged, and sometimes, according to the site conditions, the discharging end of the discharging truss 3 is inclined downward at a certain angle to facilitate the dropping of the materials on the conveyor belt. Since the materials generated during subway construction contain sediment and sewage, a flapping device 301 is arranged at the discharging end of the discharging truss 3. The flapping device 301 is arranged on the back side of the corrugated conveyor belt 202 at the lower part of the discharging truss 3, and includes six rubber rollers 302 arranged circumferentially. A rotating shaft 303 is arranged among the plurality of rubber rollers 302, and the rotating shaft 303 drives the rubber rollers 302 to rotate along the axis of the rotating shaft 303 through a motor. The flapping function is realized by the indirect contact between the plurality of rubber rollers 302 and the back of the corrugated conveyor belt 202, and the materials adhered to the corrugated conveyor belt 202 are flapped off, enhancing the conveying effect of the conveyor belt and improving the working efficiency.

[0041] Since the installation angle needs to be adjusted according to the on-site installation conditions, if only one turning roller 401 in the prior art is used for turning, turning rollers 401 with different diameters are required to cooperate with the angle adjustment. Moreover, the closer the lifting truss 2 and the discharging truss 3 are to 90 degrees, the larger the contact surface between the turning roller 401 and the corrugated conveyor belt 202, and the greater the friction force, resulting in the need for a high-power motor to drive the conveyor belt. Therefore, an arc-shaped support frame is provided at the turning point of the lifting truss 2 and the discharging truss 3 to transition the turning of the corrugated conveyor belt 202, and an adjusting device 4 is provided on the arc-shaped support frame to adjust the turning angle.

[0042] The adjusting device 4 includes a plurality of turning rollers 401, and a belt supporting device is provided on the turning rollers 401 to reduce the friction force with the corrugated conveyor belt 202. The adjusting device 4 includes adjusting discs 403 provided on the arc-shaped support frame. Two adjusting discs 403 are oppositely arranged on the arc-shaped support frame to support the turning rollers 401 and adjust the angle between the turning rollers 401 according to the usage requirements. Connecting seats 402 are provided at both ends of the turning rollers 401. A plurality of connecting seats 402 are hinged to each other, and after the adjustment is completed, the connecting seats 402 are fixed by bolts to ensure the stability of use. The specific processing method is to provide holes with multiple edges at the hinge joints between the connecting seats 402, use multi-angle bolts to clamp inside, and fix them with bolts. An adjusting rod 404 is provided at the hinge joint between the connecting seats 402. The adjusting rod 404 is connected to the adjusting disc 403. A plurality of holes are provided on the adjusting disc 403. The other end of the adjusting rod 404 is fixed on the adjusting disc 403 after the angle of the connecting seat 402 is adjusted. By adjusting the length of the adjusting rod 404, the turning angle of the turning roller 401 can be changed to meet the installation conditions at different angles and is suitable for the conveyor belt conveying at large angles, reducing the adjustment difficulty and improving the use effect.

[0043] The turning roller 401 includes a support shaft 5 disposed on a connecting seat 402. During use, the support shaft 5 is fixedly installed with the connecting seat 402. The base of the connecting seat 402 is perpendicularly fixed to the support shaft 5, facilitating the adjustment of the angle between multiple connecting seats 402. At both ends of the support shaft 5, air distribution discs 504 are fixedly provided. On the inner side surface of the air distribution disc 504, a plurality of air distribution holes 5041 are provided. On the outer side of the air distribution disc 504, quick connectors 501 are provided for connecting a gas supply device. Each air distribution hole 5041 is individually connected to a quick connector 501, and each air distribution hole 5041 can supply gas independently. The belt supporting device includes an air distribution cylinder 502 disposed on the outer side surface of the turning roller 401. On the surface of the air distribution cylinder 502, a plurality of air outlet holes 5021 are provided. The air outlet holes 5021 are distributed on the surface of the air distribution cylinder 502. During the installation process, a sealing bearing is first sleeved on the outer side of the air distribution disc 504, and then the air distribution cylinder 502 is sleeved on the outer side of the bearing. When the air distribution disc 504 supplies gas into the interior of the air distribution cylinder 502 through the air distribution holes 5041, the air outlet holes 5021 on the air distribution cylinder 502 will eject fine air columns outward, forming a relatively thin air film between the air distribution cylinder 502 and the corrugated conveyor belt 202. The baffle 104 on the side of the belt pressing wheel 103 assists to prevent the conveyor belt from deviating at a large angle. When the corrugated conveyor belt 202 passes through the turning roller 401, air flows out from the air outlet holes 5021 to form an air cushion, further reducing the contact area and friction force between the corrugated conveyor belt 202 and the turning roller 401, greatly reducing the friction force between the two, making the corrugated conveyor belt 202 more labor-saving during operation, reducing the load of the driving motor, and cooperating with the follower wheel 203 to prevent the conveyor belt from retreating, greatly improving the use effect of the conveyor.

[0044] Working principle: During use, the material first falls into the hopper of the bottom truss 1 and is evenly distributed on the corrugated conveyor belt 202 through the receiving roller group. The corrugated conveyor belt 202 starts to move driven by the driving device. After passing through the bottom truss 1, it enters the lifting truss 2. In the lifting truss 2, the corrugated conveyor belt 202 maintains a stable conveying angle under the action of the belt pressing device 101. As the corrugated conveyor belt 202 rises, the material is conveyed to the unloading truss 3 for unloading. It has the advantages of simple structure, high conveying efficiency, and low energy consumption. Especially in construction operations with large height differences such as subway tunnels and water diversion tunnels, it can significantly improve the conveying efficiency and quality of materials. At the same time, by setting auxiliary facilities such as the maintenance platform 201 and the blocking device, the reliability and safety of the conveyor are further improved. The air flow ejected from the air distribution discs 504 and the air distribution cylinders 502 on the belt supporting device and the turning roller 401 further reduces the friction force between the corrugated conveyor belt 202 and the turning roller 401, reducing the driving power and energy consumption of the motor.

[0045] Embodiment 2

[0046] According to Figure 9- Figure 12 As shown: The main difference between this embodiment and Embodiment 1 is that six air distribution plates 503 are provided inside the air distribution cylinder 502. The side surface of each air distribution plate 503 only has kidney-shaped ventilation slots 505. An air guiding cavity 5031 is provided inside the air distribution plate 503. The air outlet holes 5021 on the air distribution cylinder 502 are communicated with the air guiding cavity 5031. When in use, as long as the installation position of the turning roller 401 is fixed, the angle of each turning roller 401 in contact with the conveyor belt is basically fixed. At this time, as long as the corresponding air distribution holes 5041 are connected, it is not necessary to ventilate each air distribution hole 5041. Since the air distribution disc 504 is fixed, only when the ventilation slot 505 rotates to the air distribution hole 5041 for introducing air, the corresponding air outlet hole 5021 can discharge air, making the acting surface of the turning roller 401 more accurate, saving air source and reducing energy consumption. At the same time, the air outlet holes 5021 are inclined from the middle to both sides, so that the air outlet direction forms a V-shaped air film on the air distribution cylinder 502 to assist the conveyor belt in conveying, reducing the occurrence of deviation of the conveyor belt, greatly improving the use effect. At the same time, at the outlet of the air outlet hole 5021, the diameter of the port provided is larger than the diameter of the lower part of the air outlet hole 5021, increasing the acting area of the air flow and ensuring the use effect.

[0047] Embodiment 3

[0048] According to Figure 13 As shown: The main difference between this embodiment and Embodiment 2 is that the diameter of the air distribution cylinder 502 is set to be smaller in the middle and larger at both ends, so that when the turning roller 401 rotates, in cooperation with the air outlet direction of the air outlet holes 5021, it assists the conveyor belt to maintain the stability of the conveying direction, preventing the conveyor belt from running off track excessively, ensuring the use effect and improving the production efficiency.

[0049] Embodiment 4

[0050] According to Figure 14 As shown: The main difference between this embodiment and Embodiment 2 is that the diameter of the air distribution cylinder 502 is set to be larger in the middle and smaller at both ends. When in use, if the conveyor belt shows a deviation to one side, a certain resistance will be formed on the other side, assisting the corrugated conveyor belt 202 to reduce deviation, ensuring the use effect and improving the production efficiency.
