Abstract

This invention belongs to the field of transportation technology, and particularly relates to an intelligent suspended conveying device for construction cement. It includes a support frame with a support block inside. Rollers, driven by a motor and in contact with the inner wall of the support frame, are located on both sides of the support block.

A horizontal plate is connected to the lower side of the adjusting block. This invention uses a liquid bladder that contacts a hook. When the hook swings, the deformation energy of the liquid bladder buffers and cancels the swing. When the hook swings significantly, a magnetic field generated by energizing a coil solidifies the liquid bladder, fixing the hook and preventing it from swinging.

Description

Technical Field

[0001] This invention relates to the field of transportation technology, and in particular to an intelligent overhead conveying device for building cement. Background Technology

[0002] Suspended conveyor systems mainly refer to suspended equipment used for conveying powdery or granular materials such as cement. They are commonly found in mixing plants, cement plants, and construction sites. They can make full use of space, save ground space, avoid ground transportation congestion, reduce logistics resistance, and improve conveying efficiency. They are suitable for horizontal and inclined conveying of materials such as cement and fly ash. Generally, suspended conveyor systems are equipped with integrated sensors and control systems to achieve automatic speed regulation, material level monitoring, and fault alarms, thereby improving conveying stability.

[0003] A search revealed Chinese patent CN118560924B, which discloses a suspended material conveying device. This device includes a support frame, a guide structure, a hook structure, a locking structure, a drive structure, an adjustment structure, and a guide frame. The hook structure hooks the material to be conveyed, and the guide structure guides the hook structure's movement. The small gap between the guide structure and the guide frame prevents bouncing during guidance, thus improving stability. The drive structure moves the hook structure to convey the material. The adjustment structure adjusts the position of the conveying structure, and the locking structure allows for quick separation of the hook structure and guide structure. Once separated, the hook structure does not obstruct the conveying structure, facilitating disassembly and cleaning. However, a problem exists: when multiple cement hoppers are conveyed simultaneously, the swaying of the hoppers can cause collisions, affecting the stability of the cement conveying process.

[0004] To address the aforementioned issues, we propose an intelligent overhead conveying system for building cement. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the background art by proposing an intelligent suspended conveying device for building cement.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent suspended conveying device for building cement, comprising a support frame, a support block inside the support frame, rollers driven by a motor and in contact with the inner wall of the support frame on both sides of the support block, an adjusting block fixedly connected to the lower end of the support block, a friction adjusting mechanism on the adjusting block, a horizontal plate connected to the lower side of the adjusting block, multiple hooks fixed to the lower end of the horizontal plate, a hanging plate hanging on the multiple hooks, a cement hopper fixedly connected to the lower side of the hanging plate, and a pendulum on the horizontal plate for monitoring the swing amplitude of the cement hopper. The device includes a motion sensor, a hanging opening at the connection between the hanging plate and the hook, a liquid storage tank communicating with the hanging opening on the upper side wall of the hanging plate, a liquid bladder connected to the lower end of the liquid storage tank within the hanging opening, a piston rod slidably disposed within the liquid storage tank, a return spring sleeved on the outer wall of the piston rod, the two ends of the return spring being fixedly connected to the upper side wall of the liquid storage tank and the outer wall of the piston rod respectively, a cylinder fixedly disposed on the lower side wall of the horizontal plate, a compression plate fixedly connected to the driving end of the cylinder on the upper side of the piston rod, the liquid storage tank and the liquid bladder being filled with magnetorheological fluid, and a coil fixedly sleeved on the outer wall of the liquid storage tank and the liquid bladder.

[0007] The coil is connected to the swing sensor, cylinder and external mains power through the controller. When the swing amplitude of the cement hopper is too large, the cylinder is activated to inject magnetorheological fluid into the liquid bladder. The coil is energized to generate a magnetic field, which causes the magnetorheological fluid to turn into a solid and fix the hook.

[0008] In the aforementioned intelligent suspended conveying equipment for building cement, the support block has a groove, a limit baffle is rotatably connected in the groove, a torsion spring is connected between the limit baffle and the inner wall of the groove, a push rod is slidably inserted into the left side wall of the support block, a magnet plate is fixedly connected to the end of the push rod, a telescopic spring sleeved on the outer wall of the push rod is fixedly connected between the magnet plate and the outer wall of the support block, a magnet block is fixedly connected to the right side wall of the support block, and multiple evenly distributed limit baffles are integrally formed on the inner top wall of the support frame.

[0009] When the two support blocks approach each other, the magnetic repulsion between the magnet block and the magnet plate pushes the push rod to move. The push rod pushes the limit baffle to rotate, so that the upper end of the limit baffle is inserted between the two limit bars, preventing the support blocks from moving.

[0010] In the aforementioned intelligent suspended conveying equipment for building cement, the lower side wall of the support frame has an opening with the same width as the support block, and the support block slides along the opening.

[0011] In the aforementioned intelligent suspended conveying equipment for building cement, the friction adjustment mechanism includes a cavity formed within an adjustment block. An adjustment tube is slidably inserted into the end of the adjustment block. A piston tube is connected to the upper side wall of the adjustment tube. A piston rod is slidably disposed within the piston tube. A friction block is fixedly connected to the upper end of the piston rod. A piston plate is slidably disposed within the adjustment tube. A lifting rod is slidably inserted into the lower side wall of the adjustment block. A support spring sleeved on the outer wall of the lifting rod is fixedly connected between the adjustment block and the horizontal plate. The lower end of the lifting rod is fixedly connected to the horizontal plate. A wire rope is connected between the upper end of the lifting rod and the piston plate. A connecting spring is fixedly connected between the piston plate and the inner wall of the adjustment tube. Hydraulic oil is filled between the lower end of the piston rod and the piston plate.

[0012] In the aforementioned intelligent suspended conveying equipment for building cement, the friction block is composed of a base and a semi-metallic plate. The semi-metallic plate is positioned close to the support frame and is made of steel fiber and copper fiber.

[0013] In the aforementioned intelligent suspended conveying equipment for building cement, air outlets are provided on the inner walls of both sides of the opening, facing the support block. An air pump is provided on the support frame, and the output end of the air pump is connected to the air outlets through a multi-port pipe.

[0014] In the aforementioned intelligent suspended conveying equipment for building cement, a fixed pulley is installed inside the cavity, and the steel wire rope is arranged to pass around the fixed pulley.

[0015] Compared with existing technologies, the advantages of this intelligent suspended conveyor system for building cement are:

[0016] 1. A limit baffle is set up. When the two support blocks are close to each other, the magnetic repulsion between the magnetic block and the magnetic plate pushes the push rod to move. The push rod pushes the limit baffle to rotate, so that the upper end of the limit baffle is inserted between the two limit bars, preventing the support blocks from moving. By preventing the right support block from moving, the two support blocks are prevented from contacting each other, thus avoiding collision between the two support blocks or the two cement hoppers and ensuring the stability of the cement hopper during the cement transportation process.

[0017] 2. The friction block is installed so that when a large amount of cement is contained, the weight of the block overcomes the elasticity of the support spring, and the lifting rod moves downward. The two piston plates pulled by the wire rope move closer to each other, and the hydraulic oil in the piston tube flows into the regulating pipe, thus reducing the height of the friction block. This avoids the friction between the friction block and the support frame being too large when the cement hopper is heavy, which would affect the movement of the support block.

[0018] When the cement hopper contains a small amount of cement, the lifting rod moves upward under the elastic force of the support spring. Under the elastic force of the connecting spring, the two piston plates move away from each other, squeezing hydraulic oil into the piston tube to lift the friction block, so that the friction block contacts the outer wall of the support frame, increasing the friction between the support block and the support frame. By increasing the friction, the problem of swaying and shaking that occurs when the cement hopper is light is avoided, ensuring the stability of the conveying.

[0019] 3. When the hook swings, it will compress the liquid bladder and deform it. Under the reverse elastic force of the return spring, it will prevent the magnetorheological fluid from flowing upward, that is, prevent the deformation of the liquid bladder, thus overcoming the swing of the hook. When the swing amplitude of the cement hopper is large, the swing sensor will transmit the signal to the controller. The controller will transmit the signal to the cylinder and connect the coil to the mains power. The cylinder drive end extends to inject the magnetorheological fluid into the liquid bladder. After the current is passed into the coil, a magnetic field is formed. Under the action of the magnetic field, the magnetorheological fluid changes from liquid to solid or near-solid state, preventing the hook from swinging and ensuring the stability of the cement hopper.

[0020] This invention establishes a liquid bladder that contacts the hook. When the hook swings, the deformation energy of the liquid bladder buffers and counteracts the swing. When the swing amplitude of the hook is large, a magnetic field is generated by energizing the coil to solidify the liquid bladder, fixing the hook and preventing it from swinging. This ensures that the cement hopper will not shake excessively and cause collisions. At the same time, by setting a friction block that contacts the support frame, the friction force at the contact position is adjusted according to the different weights of the cement hopper, ensuring the stability of cement delivery.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] Reference Figures 1-8An intelligent suspended conveying device for building cement includes a support frame 1, a support block 2 inside the support frame 1, and rollers 3 on both sides of the support block 2 that are driven by a motor and contact the inner wall of the support frame 1. The rollers 3 move along the inner wall of the support frame 1 to move the support block 2. A groove 25 is opened on the support block 2, and a limit baffle 26 is rotatably connected in the groove 25. A torsion spring 27 is connected between the limit baffle 26 and the inner wall of the groove 25. A push rod 30 is slidably inserted into the left side wall of the support block 2. A magnet plate 28 is fixedly connected to the end of the push rod 30. A telescopic spring 29 sleeved on the outer wall of the push rod 30 is fixedly connected between the magnet plate 28 and the outer wall of the support block 2. A magnet block 31 is fixedly connected to the right side wall of the support block 2. Multiple evenly distributed limit baffles 32 are integrally formed on the inner top wall of the support frame 1.

[0035] When the two support blocks 2 approach each other, the magnetic repulsion between the magnet block 31 and the magnet plate 28 pushes the push rod 30 to move. The push rod 30 pushes the limiting baffle 26 to rotate, so that the upper end of the limiting baffle 26 is inserted between the two limiting bars 32, preventing the support block 2 from moving. By preventing the right support block 2 from moving, the two support blocks 2 are prevented from contacting each other, avoiding collision between the two support blocks 2 or the two cement hoppers 8, and ensuring the stability of the cement hopper 8 during cement transportation. When the left support block 2 moves forward, the two support blocks 2 move away from each other, and the magnetic repulsion between the magnet block 31 and the magnet plate 28 is no longer generated. Under the reverse elastic force of the torsion spring 27, the limiting baffle 26 rotates, and the end of the limiting baffle 26 disengages from the limiting bars 32. At this time, the support block 2 can continue to move forward. The magnetic strength between the magnet block 31 and the magnet plate 28 can be adjusted and controlled by the material and size of the magnet block 31 and the magnet plate 28.

[0036] The lower side wall of the support frame 1 has an opening with the same width as the support block 2. The support block 2 slides along the opening. The inner walls on both sides of the opening have air outlets facing the support block 2. The support frame 1 is equipped with an air pump. The output end of the air pump is connected to the air outlet through a multi-port pipe. During the movement of the support block 2, the air pump outputs high-pressure airflow from the air outlet and blows it into contact with the outer wall of the support block 2. The airflow can support the support block 2, prevent the support block 2 from shaking, and ensure the stability of the support block 2 during movement. At the same time, the airflow can also reduce the friction at the contact point between the support block 2 and the support frame 1. By centering the support block 2 and reducing the contact area between the support block 2 and the support frame 1, friction is reduced, making the sliding of the support block 2 smoother and more stable.

[0037] An adjusting block 4 is fixedly connected to the lower end of the support block 2. The adjusting block 4 is equipped with a friction adjusting mechanism, which includes a cavity within the adjusting block 4. An adjusting tube 9 is slidably inserted into the end of the adjusting block 4. A piston tube 14 is connected to the upper side wall of the adjusting tube 9. A piston rod is slidably installed inside the piston tube 14. A friction block 15 is fixedly connected to the upper end of the piston rod. A piston plate 12 is slidably installed inside the adjusting tube 9. A lifting rod 5 is slidably inserted into the lower side wall of the adjusting block 4. A support spring 6, sleeved on the outer wall of the lifting rod 5, is fixedly connected between the adjusting block 4 and the horizontal plate 7. The lower end of the lifting rod 5 is fixedly connected to the horizontal plate 7. A wire rope 11 is connected between the upper end of the lifting rod 5 and the piston plate 12. A fixed pulley 10 is installed inside the cavity. The wire rope 11 passes around the fixed pulley 10. A connecting spring 13 is fixedly connected between the piston plate 12 and the inner wall of the adjusting tube 9. Hydraulic oil is filled between the lower end of the piston rod and the piston plate 12. Oil is an existing fluid, and the hydraulic medium used in hydraulic systems that utilize liquid pressure energy plays a role in energy transmission, anti-wear, system lubrication, corrosion prevention, rust prevention, and cooling in hydraulic systems. Here, the friction block 15 moves up and down through the flow of hydraulic oil. The friction block 15 is composed of a base and a semi-metallic plate. The semi-metallic plate is set close to the support frame 1. The base can be made of wood, metal, or other materials with support capabilities. The semi-metallic plate is made of steel fiber and copper fiber. Cement is transported in the cement hopper 8. When a lot of cement is contained, under the action of weight, the lifting rod 5 moves down, overcoming the elastic force of the support spring 6. The two piston plates 12 pulled by the wire rope 11 move closer to each other, and the hydraulic oil in the piston tube 14 flows into the regulating pipe 9. The height of the friction block 15 is reduced, which avoids the friction between the friction block 15 and the support frame 1 being too large when the cement hopper 8 is heavy, thus affecting the movement of the support block 2.

[0038] When the cement hopper is less than usual, the lifting rod 5 moves upward under the elastic force of the support spring 6. Under the elastic force of the connecting spring 13, the two piston plates 12 move away from each other, squeezing hydraulic oil into the piston tube 14 to lift the friction block 15, so that the friction block 15 contacts the outer wall of the support frame 1, increasing the friction between the support block 2 and the support frame 1. By increasing the friction, the problem of easy swinging and shaking when the cement hopper 8 is light is avoided, ensuring the stability of the conveying.

[0039] A horizontal plate 7 is connected to the lower side of the adjusting block 4. Multiple hooks 16 are fixed to the lower end of the horizontal plate 7, and a hanging plate 17 is hung on each of the hooks 16. A cement hopper 8 is fixedly connected to the lower side of the hanging plate 17. A swing sensor for monitoring the swing amplitude of the cement hopper 8 is provided on the horizontal plate 7. A hanging opening 18 is provided at the connection between the hanging plate 17 and the hooks 16. A liquid storage tank 19 communicating with the hanging opening 18 is provided on the upper side wall of the hanging plate 17. A liquid bladder 24 located inside the hanging opening 18 is connected to the lower end of the liquid storage tank 19. A piston column 20 is slidably arranged inside the liquid storage tank 19. A return spring 21 is sleeved on the outer wall of the piston column 20. The two ends of the return spring 21 are respectively connected to the liquid storage tank. The upper side wall of 19 and the outer wall of piston column 20 are fixedly connected. The lower side wall of the horizontal plate 7 is fixed with cylinder 22. The driving end of cylinder 22 is fixedly connected with extrusion plate 23 located on the upper side of piston column 20. The liquid storage tank 19 and liquid bladder 24 are filled with magnetorheological fluid. The outer wall of liquid storage tank 19 and liquid bladder 24 is fixedly fitted with coil. Magnetorheological fluid is an existing fluid component. It is a new type of fluid with controllable fluidity. It is a relatively active research area in smart materials. When there is no external magnetic field, it exhibits the characteristics of low viscosity Newtonian fluid. When an external magnetic field is applied, it exhibits the characteristics of high viscosity and low fluidity Bingham fluid. The viscosity of the liquid has a corresponding relationship with the magnetic flux.

[0040] The coil is connected to the swing sensor, cylinder 22, and external mains power through the controller. When the swing amplitude of the cement hopper 8 is too large, the cylinder 22 is activated to inject magnetorheological fluid into the liquid bladder 24. The coil is energized to generate a magnetic field, which causes the magnetorheological fluid to turn into a solid state and fix the hook 16. Under normal conditions, the magnetorheological fluid is in a liquid state. When the hook 16 swings, it will squeeze the liquid bladder 24 to deform. Under the reverse elastic force of the return spring 21, the magnetorheological fluid will be prevented from flowing upward, that is, the deformation of the liquid bladder 24 will be prevented, thus overcoming the swing of the hook 16. When the swing amplitude of the cement hopper 8 is large, the swing sensor transmits the signal to the controller. The controller transmits the signal to the cylinder 22 and connects the coil to the mains power. The drive end of the cylinder 22 extends to inject magnetorheological fluid into the liquid bladder 24. After the current is passed through the coil, a magnetic field is formed. Under the action of the magnetic field, the magnetorheological fluid changes from a liquid state to a solid or near-solid state, preventing the hook 16 from swinging and ensuring the stability of the cement hopper 8.

[0041] During small swings, the deformation of the liquid bladder 24 buffers the swing. During large swings, the solidification of the liquid bladder 24 clamps and fixes the hook 16, preventing the hook 16 from swinging. This method ensures that the hook 16 can be removed while also achieving small swing buffering and large swing fixation to eliminate the swing, thereby ensuring the stability of the overall conveying process.

[0042] In summary, the specific overhead conveying steps include:

[0043] Hang the hook 16 inside the hanging opening 18, and put the cement into the cement hopper 8;

[0044] The motor drives the roller 3 to rotate, causing the roller 3 to move along the inner wall of the support frame 1, so that the whole unit moves along the direction of the support frame 1 to complete the cement conveying.

[0045] When the two support blocks 2 approach each other, the magnetic repulsion between the magnet block 31 and the magnet plate 28 pushes the push rod 30 to move. The push rod 30 pushes the limit baffle 26 to rotate, so that the upper end of the limit baffle 26 is inserted between the two limit baffles 32, preventing the support block 2 from moving. By preventing the support block 2 on the right side from moving, the two support blocks 2 are prevented from contacting each other, thus avoiding collision between the two support blocks 2 or the two cement hoppers 8.

[0046] Cement hopper 8 is used for conveying cement. When the cement hopper is full, the lifting rod 5 moves downward, and the two piston plates 12 pulled by the wire rope 11 move closer to each other. The hydraulic oil in the piston tube 14 flows into the regulating pipe 9, and the height of the friction block 15 decreases. This avoids the friction between the friction block 15 and the support frame 1 being too strong when the cement hopper 8 is heavy, which would affect the movement of the support block 2. Similarly, when the cement hopper 8 is light, the two piston plates 12 move away from each other, and the hydraulic oil is squeezed into the piston tube 14 to lift the friction block 15, so that the friction block 15 contacts the outer wall of the support frame 1, increasing the friction between the support block 2 and the support frame 1. By increasing the friction, the problem of swinging and shaking when the cement hopper 8 is light is avoided.

[0047] During the conveying process, when the contact point between the roller 3 and the support frame 1 vibrates or when the cement hopper 8 swings due to external force, the hook 16 will squeeze the liquid bladder 24 to deform. Under the reverse elastic force of the return spring 21, the magnetorheological fluid will be prevented from flowing upward, thus preventing the deformation of the liquid bladder 24 and overcoming the swing of the hook 16. When the swing amplitude is large, the drive end of the cylinder 22 extends to inject the magnetorheological fluid into the liquid bladder 24. After the current is passed through the coil, a magnetic field is formed. Under the action of the magnetic field, the magnetorheological fluid changes from liquid to solid or near-solid state, preventing the hook 16 from swinging and ensuring the stability of the cement hopper 8.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
