Description

Technical Field

[0001] This invention relates to the field of belt conveyor accessories technology, and in particular to an intelligent hydraulic correction device. Background Technology

[0002] Belt conveyors are widely used in bulk material conveying industries such as coal, metallurgy, mining, ports, chemicals, light industry, petroleum, and machinery. They are characterized by a wide range of applicable materials, large conveying capacity, high climbing ability, low operating costs, convenient use and maintenance, and ease of automation control. Therefore, belt conveyors are widely used in the bulk material conveying industry. However, due to long conveying distances, uneven material distribution, and inconsistent installation precision, belt misalignment is prone to occur, causing material spillage along the line, conveyor belt damage, and production stoppages, affecting daily operations. Misalignment caused by uneven material distribution is particularly difficult to correct. Industry methods to prevent belt misalignment mainly involve changing the displacement of the belt conveyor rollers and installing correction devices along the belt line. Currently, existing correction devices primarily use friction to correct belt misalignment. When the belt deviates, the correction device changes the angle between the idler roller axis and the belt conveyor axis, generating a force that forms an angle with the belt's running direction, thus creating friction to center the belt. However, this type of correction device can only change a small angle, has limited friction, and cannot center materials that are not centered.

[0003] For example, CN113548377A discloses a high-efficiency deviation correction device and method for idler rollers on a belt conveyor, including an idler roller assembly, a transmission assembly, an execution assembly, a sensing assembly, and a control system. The sensing assembly is mounted on the idler roller assembly and collects the lateral pressure exerted by the idler roller assembly on the sensing assembly when it deviates from its designated path. The sensing assembly is data-connected to the control system, transmitting the lateral pressure data from the idler roller assembly to the control system. The control system is signal-connected to the execution assembly. The execution assembly is driven by the transmission assembly. The transmission assembly is driven by both sides of the idler roller assembly, transmitting the power from the execution assembly to the idler roller assembly, thereby adjusting the idler roller assembly to correct its deviation. This solution uses the sensing assembly to detect the deviation of the idler roller assembly and connects the execution assembly and transmission assembly through the control system to drive the idler roller assembly to move and correct its deviation, significantly improving the deviation correction efficiency of the belt conveyor during operation.

[0004] The above-mentioned technical solutions have problems in practical applications, such as a small correction range, limited friction, and inability to handle non-centered materials.

[0005] Therefore, it is necessary to invent an intelligent hydraulic correction device to solve the above problems. Summary of the Invention

A connecting block is fixedly provided at the bottom center of the support frame, and a connecting groove is provided through the center of the connecting block. A pin is provided inside the connecting groove, and the pin is located at the center of the upper surface of the bracket through a support seat.

[0010] A fixed frame, located above the support frame;

[0011] Two support rollers are provided, both located inside the fixed frame, and the support rollers are in contact with the inner wall of the belt conveyor belt;

[0012] Two correction rollers are provided, which are located on both sides of the fixed frame, and a shaft is provided in the middle of the correction roller;

[0013] The inspection wheel is located between the two support rollers and is in contact with the inner wall of the conveyor belt.

[0014] Preferably, a hydraulic rod is disposed between the support frame and the bracket. The hydraulic rod is used to push the support frame and drive the support roller and the correction roller to move. The top end of the hydraulic rod is connected to the bottom end of the support frame through a connecting pin.

[0015] The slide is located at the bottom end of the hydraulic rod and is connected to the bottom end of the hydraulic rod via a pin seat.

[0016] Preferably, a sliding groove is provided on the upper surface of the bracket, and the slide block is slidably disposed inside the sliding groove;

[0017] The threaded groove and threaded rod are provided. The threaded groove is located in the middle of the slide block, and the threaded rod is located inside the threaded groove and is rotatably located inside the bracket through a bearing. The threaded groove and threaded rod are used to adjust the position of the slide block.

[0018] Preferably, the support arm is mounted on the top of the shaft via a pin;

[0019] A connecting arm is located on the outside of the fixed frame, and a shock-absorbing telescopic rod is provided between the connecting arm and the support arm.

[0020] Preferably, the movable seat is located outside the fixed frame and connected to the bottom end of the connecting arm via a pin;

[0021] The slide bar is located above the support frame. Both sides of the movable seat are provided with sliding sleeves that can slide on the outside of the slide bar. The bottom end of the fixed frame is provided with a fixed seat, and the fixed seat is fixedly located in the middle of the slide bar.

[0022] The hydraulic column is located above the support frame and connected to the bottom of the movable seat via a connecting plate.

[0023] Preferably, the movable sleeve is located in the middle of the detection wheel and is mounted in the middle of the fixed frame via a support rod;

[0024] An extension plate, located at one end of the movable sleeve;

[0025] A displacement sensor, located between the fixed frame and the extension plate, can detect the horizontal movement of the detection wheel to detect the belt offset.

[0026] Preferably, the anti-slip block is located on the outer side wall of the detection wheel and is designed with an inclined structure.

[0027] Preferably, the correction roller is a conical structure and is inclined.

[0028] Preferably, the connecting groove is configured as a strip structure.

[0029] Preferably, the bracket has mounting bases at both ends, and the mounting bases have multiple mounting holes in the middle.

[0030] The technical effects and advantages of this invention are as follows:

[0031] 1. This invention provides a support frame above a bracket, with a support roller and a correction roller above the support frame. The support roller and correction roller support the belt of the conveyor belt. A connecting block is installed below the support frame, with a pin in the connecting groove in the middle of the connecting block. The pin engages with the connecting block, allowing the support frame to deflect to a certain extent. When correcting the belt, the support frame drives the support roller and correction roller to move, lifting the belt on the side with more material to a certain height. This causes the force balance point of the two belts to shift, creating a force difference that pulls the belt back to its original position and restores normal movement. At the same time, lifting one side of the belt allows the offset material to move to the other side, thus solving the problem of material misalignment.

[0032] 2. This invention provides a support arm at one end of the belt alignment roller. The bottom end of the support arm is connected to a movable seat via a shock-absorbing telescopic rod. The bottom end of the movable seat is connected to a hydraulic column via a connecting plate. The hydraulic column is positioned above the support frame. The hydraulic column can drive the support arm to move via the movable seat, thereby adjusting the angle of the belt alignment roller. When correcting the belt alignment, the hydraulic column can be adjusted independently to achieve unilateral belt alignment, or the position of the belt alignment roller can be adjusted simultaneously while adjusting the position of the support frame, thereby increasing the alignment range of the device.

[0033] 3. This invention sets a detection wheel between two support rollers. The detection wheel can fit against the inner wall of the belt. When the belt deviates, the detection wheel slides horizontally following the belt's deviation. The sliding of the detection wheel can be detected by a displacement sensor to obtain the belt deviation amount. This achieves the effect of real-time monitoring of belt deviation, which facilitates belt correction work. Attached Figure Description

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] like Figures 1 to 9 As shown, the intelligent hydraulic belt alignment device provided by the present invention is essentially a belt alignment device with a support roller 4 and an alignment roller 5 that can be simultaneously deflected. The support roller 4 and the alignment roller 5 are both arranged above the support frame 2, and the support frame 2 can deflect above the bracket 1. When the belt is aligned, the support frame 2 deflects under the push of the hydraulic rod 25. The support frame 2 drives the support roller 4 and the alignment roller 5 to deflect, lifting the belt on the side with more material to a certain height, so that the force balance point of the belt on both sides shifts and a force difference is generated, so as to pull the belt back to its original position and restore normal movement. At the same time, the lifting of one side of the belt allows the offset material to move to the other side, thereby solving the problem of material not being centered. Furthermore, the positions of the two alignment rollers 5 can be adjusted separately by two hydraulic columns 553 to achieve unilateral belt alignment. The positions of the alignment rollers 5 can also be adjusted simultaneously when adjusting the position of the support frame 2 to improve the alignment range of the device.

[0046] In terms of specific structural installation, the structural body can be constructed according to the inventive concept of this embodiment. In this embodiment, no special limitations are imposed.

[0047] In this embodiment, an intelligent hydraulic correction device includes:

[0048] The bracket 1 is designed as a straight structure and installed inside the frame of the belt conveyor. Both ends of the bracket 1 are provided with mounting seats 11, and the middle of the mounting seats 11 is provided with multiple mounting holes.

[0049] Support frame 2 is located above bracket 1 and is designed with a "︺" shape. A connecting block 21 is fixedly provided at the middle of the bottom end of support frame 2, and a connecting groove 22 is provided through the middle of the connecting block 21. A pin 23 is provided inside the connecting groove 22, and the pin 23 is provided at the middle of the upper surface of bracket 1 through support seat 24. The connecting groove 22 is designed with a strip structure. The design of the strip structure makes the connecting groove 22 and the pin 23 have a certain amount of space to avoid damage to support frame 2 caused by the difference in drive between the two hydraulic rods 25.

[0050] Hydraulic rod 25 is located between support frame 2 and bracket 1. Hydraulic rod 25 is used to push support frame 2 and drive support roller 4 and correction roller 5 to move. The top end of hydraulic rod 25 is connected to the bottom end of support frame 2 through connecting pin 251.

[0051] The slide 26 is located at the bottom end of the hydraulic rod 25 and is connected to the bottom end of the hydraulic rod 25 via a pin seat 252;

[0052] The slide groove 261 is provided on the upper surface of the bracket 1, and the slide block 26 is slidably disposed inside the slide groove 261;

[0053] The threaded groove 262 and the threaded rod 263 are located in the middle of the slide block 26. The threaded rod 263 is located inside the threaded groove 262 and is rotatably mounted inside the bracket 1 through a bearing. The threaded groove 262 and the threaded rod 263 are used to adjust the position of the slide block 26. The threaded rod 263 and the threaded groove 262 cooperate to adjust the position of the slide block 26. The slide block 26 can drive the bottom end of the hydraulic rod 25 to move, so as to adjust the initial inclination of the support frame 2, so as to facilitate the installation and debugging of the device.

[0054] The fixing frame 3 is located above the support frame 2;

[0055] Support roller 4, which has two and is located inside the fixed frame 3, and the support roller 4 is in contact with the inner wall of the belt of the conveyor belt;

[0056] There are two correction rollers 5, which are located on both sides of the fixed frame 3. The middle part of the correction roller 5 is provided with a shaft 51. The correction roller 5 is designed as a tapered structure and is inclined. The inclined structure design facilitates the correction roller 5 to guide the belt towards the support roller 4.

[0057] Support arm 52 is mounted on the top of shaft 51 via a pin;

[0058] The connecting arm 53 is located on the outside of the fixed frame 3. A shock-absorbing telescopic rod 54 is provided between the connecting arm 53 and the support arm 52. The shock-absorbing telescopic rod 54 can play a shock-absorbing and buffering role for the straightening roller 5, so as to ensure the stability of the straightening roller 5 when it is impacted by the material above the belt.

[0059] The movable seat 55 is located outside the fixed frame 3 and is connected to the bottom end of the connecting arm 53 by a pin.

[0060] The slide rod 56 is located above the support frame 2. Both sides of the movable seat 55 are provided with sliding sleeves 551 that can slide on the outside of the slide rod 56. The bottom end of the fixed frame 3 is provided with a fixed seat 31, and the fixed seat 31 is fixedly located in the middle of the slide rod 56.

[0061] The hydraulic column 553 is located above the support frame 2 and is connected to the bottom end of the movable seat 55 through the connecting plate 552. The hydraulic column 553 can push the movable seat 55 to move, and the movable seat 55 can drive one end of the correction roller 5 to move through the connecting arm 53, so that the correction roller 5 can be adjusted individually.

[0062] The detection wheel 6 is located between the two support rollers 4 and is in contact with the inner wall of the belt conveyor belt;

[0063] The movable sleeve 61 is located in the middle of the detection wheel 6 and is mounted in the middle of the fixed frame 3 via the support rod 62. The detection wheel 6 can rotate around the movable sleeve 61.

[0064] Extension plate 63, which is located at one end of movable sleeve 61;

[0065] The displacement sensor 64 is located between the fixed frame 3 and the extension plate 63. The displacement sensor 64 can identify the horizontal movement of the detection wheel 6 to detect the belt offset. The anti-slip block 65 is located on the outer wall of the detection wheel 6 and is set as an inclined structure. The anti-slip block 65 can increase the friction between the detection wheel 6 and the belt to ensure that the detection wheel 6 can follow the belt movement.

[0066] When using the intelligent hydraulic correction device of this embodiment, the bracket 1 can be installed in the frame of the belt conveyor by mounting base 11 and bolts. The support roller 4, correction roller 5 and detection wheel 6 can be in contact with the belt of the belt conveyor. During the operation of the belt, the detection wheel 6 rotates with the belt under the action of friction. When the belt deviates, the detection wheel 6 deviates with the belt. The deviation of the detection wheel 6 is detected and identified by the displacement sensor 64 to obtain the belt deviation.

[0067] When the belt is being corrected, the two sets of hydraulic rods 25 move in opposite directions. The hydraulic rods 25 can push the support frame 2, causing the support frame 2 to deflect around the pin 23. The support frame 2 drives the support roller 4 and the correction roller 5 to deflect. The support roller 4 and the correction roller 5 can drive the belt to deflect, causing the force balance point of the belt on both sides to shift and generate a force difference, so as to pull the belt back to its original position and restore normal movement. At the same time, the belt being lifted on one side can allow the offset material to move to the other side, thereby solving the problem of material not being centered.

[0068] At the same time, the hydraulic column 553 can push the movable seat 55 to move, and the movable seat 55 can drive one end of the correction roller 5 to move through the connecting arm 53, so that the correction roller 5 can be adjusted individually to achieve individual correction adjustment on one side of the belt, and can also play an auxiliary correction effect when the support frame 2 deflects.

[0069] Furthermore, during the installation process, by rotating the threaded rod 263, which engages with the threaded groove 262, the position of the slide block 26 can be adjusted. The slide block 26 can then drive the bottom end of the hydraulic rod 25 to move, thereby adjusting the initial inclination of the support frame 2, which facilitates the installation and debugging of the device.

[0070] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
