Description

Technical Field

[0001] This application relates to the field of overhead conveying equipment technology, and in particular to an overhead conveying equipment for Calacatta marble. Background Technology

[0002] Calacatta marble is a high-end building decoration material, typically characterized by its large size and high density. During stone processing and transportation, overhead conveyor systems are commonly used to transport fully loaded marble frames along guide rails to designated workstations. A lifting assembly then lowers the frames onto a conveyor for unloading. Currently, there are two main methods for connecting and disconnecting the lifting assembly from the frame in overhead conveyor systems: one is manual insertion and removal of hooks at heights or in confined spaces, which is not only inefficient but also poses significant safety hazards and is difficult to meet the demands of continuous automated production; the other method involves adding hydraulic cylinders, electric actuators, or other active drive components to the lifting assembly to control the locking and releasing of the hooks.

[0003] However, this structure suffers from severe self-weight load defects. Since the marble slabs and the material frame themselves have a certain weight, the additional unlocking drive components significantly increase the overall weight of the suspended end. This not only increases the operating load on the guide rail sliding and mechanism lifting, exacerbating energy consumption, but also increases wear and fatigue damage to transmission components, shortening the equipment's service life. Furthermore, the traditional equipment's drive unlocking structure is complex and has uneven weight distribution, making it prone to swaying and deviation during heavy-load conveying. This not only affects the conveying alignment accuracy but also easily leads to the risk of unhooking and material falling, causing damage to the marble slabs. In addition, the additional drive structure requires matching electrical control and hydraulic systems, further increasing the equipment's weight and maintenance costs. It cannot meet the requirements of lightweight, low-loss, and highly safe heavy-load continuous conveying operations. Therefore, a suspended conveying device for Calacatta marble is proposed to solve the above problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this application provides a suspended conveying device for Calacatta marble, which features automatic unlocking and unloading, achieving advantages such as high efficiency and lightweight suspended conveying, thus solving the aforementioned problems.

[0005] This application provides a suspended conveying device for Calacatta marble, which adopts the following technical solution: A suspended conveying device for Calacatta marble includes a suspended conveying device consisting of a guide rail frame, a guide rail seat, a lifting assembly, a material frame, and a conveyor. The lifting assembly is located below the guide rail seat and consists of a top plate, a bottom plate, and a hydraulic telescopic rod. The bottom side of the bottom plate is provided with a hook mechanism that engages with the material frame and slides on the guide rail frame in conjunction with the guide rail seat, enabling the Calacatta marble to be transferred onto the conveyor. The hooking mechanism consists of a hook base, a hook member, an abutment component, and a switch component. The hook base is detachably installed on the bottom side of the base plate. The hook member includes a detachably connected telescopic shaft and an abutment base. The telescopic shaft passes through the interior of the hook base, and the other end of the telescopic shaft is used in conjunction with the abutment component. The abutment assembly includes an arc-shaped rod slidably disposed on the hook seat, a pressure plate fixed to the top of the arc-shaped rod, and a connecting seat fixed to the other end of the telescopic shaft. A connecting rod is hinged between the connecting seat and the telescopic shaft. A limiting shaft that is inserted into the telescopic shaft is threaded on the inner side of the pressure plate. A return spring is fixed on the top side of the arc-shaped rod.

[0006] Optionally: the hydraulic telescopic rod is fixed to the top side of the top plate, and its output end is fixed to the upper surface of the bottom plate; a limiting guide rod penetrating the interior of the top plate is fixed to the top side of the bottom plate by bolts; the conveyor is located below the lifting assembly.

[0007] Optionally: The hook seat has a cavity inside, the telescopic shaft and the bow-shaped rod both pass through the cavity, a pressure sensing module is embedded on the top side of the abutment seat, an abutment slide is opened on the side wall of the material frame, and the abutment seat extends into the abutment slide.

[0008] Optionally, the switch assembly includes a mounting base, a magnetic rod that slides through the interior of the mounting base, and a plug rod threaded onto one end of the magnetic rod. A second return spring is wound around the outer surface of the magnetic rod. The plug rod is inserted into the bow-shaped rod. The mounting base is bolted to the bottom side of the hook seat.

[0009] Optionally, the switch assembly further includes a support plate, a magnetic base, and a magnetic block. The support plate is fixed to the outer wall of the conveyor, the magnetic block is embedded inside the magnetic base, and the magnetic base is fixed to the top side of the support plate.

[0010] Optionally: The magnetic rod and the magnetic base have opposite magnetic poles. When the hook base moves down, the magnetic rod and the magnetic base have opposite magnetic poles, causing the insertion rod to disengage from the bow-shaped rod. As the hook base moves down, the bottom end of the bow-shaped rod contacts the support plate and moves upward. The connecting rod drives the telescopic axis to extend into the hook base, causing the abutment seat to automatically disengage from the material frame.

[0011] Optionally, the hooking mechanism further includes a locking assembly, which includes a hollow compression sleeve, a locking element, and a guide element. The compression sleeve and bolts are fixed to the outer surface of the telescopic shaft, and the compression sleeve and the locking element are interference-fitted.

[0012] Optionally: The locking component includes several elastic blocks, which are distributed equidistantly in a ring, and the inner sides of each elastic block can be detachably fitted with a locking block, wherein the locking block is arc-shaped and adapted to the shape of the telescopic shaft.

[0013] Optionally: The outer side of the plurality of elastic blocks and the inner side of the extrusion sleeve are provided with pressure surfaces. When the extrusion sleeve moves with the telescopic shaft, the pressure surfaces and the plurality of elastic blocks are used to make the locking block fit against the outer surface of the telescopic shaft.

[0014] Optionally, the guide includes a limiting seat fixed to the outer wall of the hook seat and a slide rod fixed to the outer wall of the extrusion sleeve, wherein the slide rod passes through the interior of the limiting seat, and a buffer spring is fixed between the outer surface of the slide rod and the outer wall of the limiting seat.

[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. This invention, through the magnetic attraction triggering structure of the switch component and the structural cooperation of the abutment component, can automatically complete the unlocking, unloading, and material unloading operations during the process of the equipment descending and aligning with the conveyor without manual intervention, replacing the traditional manual disassembly of hooks operation mode, greatly improving the conveying and transfer efficiency of Calacatta marble slabs, and adapting to the continuous operation requirements of the assembly line.

[0016] 2. This invention abandons the traditional active drive unlocking mode and adopts a magnetic passive unlocking and mechanical contact unlocking structure. No additional unlocking drive components are required. The device can automatically unlock and unblock through its own mechanical stroke of descent and alignment and the opposing magnetic pole attraction. This reduces the weight of the device from the source and reduces the load loss of the guide rail sliding and lifting operation.

[0017] 3. This invention achieves a dual protection structure through mechanical locking of the switch assembly and adaptive clamping locking of the locking assembly. In the conveying state, the insertion rod is fixed to the bow-shaped rod and the locking block clamps the telescopic shaft, effectively preventing loosening, unhooking and falling during heavy-load conveying, thus taking into account both lightweight operation and heavy-load operation safety.

[0018] 4. This invention can issue an alarm in case of abnormality through the pressure sensing module, further ensuring the safety of heavy-duty conveying; at the same time, when it is necessary to start the contact component, the pressure monitoring of the pressure sensing module can be used to further determine the downward movement of the lifting component.

[0019] 5. In this invention, the plug rod of the switch assembly and the locking assembly have a fixed timing relationship. The first lock is released by magnetically pulling the pin, which must be completed before the bow-shaped rod touches the support plate and the second lock is released. Because the magnetic seat is fixed at a certain height above the support plate, when the hook seat descends, it first enters the magnetic range to pull the pin, and only after continuing to descend does it touch the support plate and pull back the telescopic shaft. If the magnetic force fails, even if the bow-shaped rod touches the support plate, it will not be able to move upward because the plug rod has not been pulled out, thereby locking the telescopic shaft and preventing accidental disengagement.

[0022] The following is in conjunction with the appendix Figures 1-9 This application will be described in further detail.

[0023] like Figures 1-2 As shown, this embodiment provides a suspended conveying device for Calacatta marble, including a suspended conveying device 1 and a conveyor 15 below it. The suspended conveying device 1 consists of a guide rail frame 11, a guide rail seat 12 slidably connected to the guide rail frame 11, a lifting assembly 13 fixed below the guide rail seat 12, and a material frame 14 detachably connected via hooking mechanisms 2. Multiple hooking mechanisms 2 are used. This solution requires no manual intervention; the unlocking, unhooking, and unloading operations are automatically completed during the lowering and alignment of the equipment with the conveyor 15, replacing the traditional manual disassembly of hooks and thus improving the conveying and transfer efficiency of Calacatta marble slabs.

[0024] like Figure 2 and Figure 3 As shown, the lifting assembly 13 includes a top plate 131, a bottom plate 132, and a hydraulic telescopic rod 133. The top plate 131 is fixed to the bottom surface of the guide rail seat 12. The cylinder end of the hydraulic telescopic rod 133 is fixed to the top surface of the top plate 131, and its telescopic end passes through the top plate 131 and is fixed to the bottom plate 132. To ensure smooth lifting, four limiting guide rods 134 are vertically fixed at the four corners of the top surface of the bottom plate 132. The limiting guide rods 134 slide through the corresponding guide holes on the top plate 131. This lifting assembly 13 only provides vertical movement and does not undertake any unlocking drive function, thereby avoiding additional weight to the equipment.

[0025] like Figures 3-5 As shown, the hooking mechanism 2 includes a hook base 21, a hook member 22, an abutment component 23, a locking component 24, and a switch component 25. The hook base 21 is detachably fixed to the lower surface of the base plate 132 by bolts, and has a cavity 211 inside. It should be noted that the hooking mechanism 2 abandons the traditional active drive unlocking mode and adopts a magnetic passive unlocking and mechanical contact unlocking structure. It does not require additional hydraulic cylinders, motors, or other drive components, reducing the weight of the equipment and reducing the load loss during guide rail sliding and lifting operations.

[0026] like Figure 4 and Figure 5As shown, the hook 22 includes a telescopic shaft 221 and an abutment seat 222. The telescopic shaft 221 horizontally passes through the hook seat 21 and its chamber 211. The abutment seat 222 is fixed to the end of the telescopic shaft 221 facing the material frame 14 by a threaded connection, and a pressure sensing module 223 is embedded on the top surface of the abutment seat 222 for real-time monitoring of the hooking pressure with the material frame 14. The material frame 14 has an abutment sliding opening on the corresponding side wall, and the abutment seat 222 slides and engages in the sliding opening. The pressure sensing module 223 can issue an alarm in case of abnormality, further ensuring the safety of heavy-load conveying; at the same time, when it is necessary to start the abutment component 23, the downward movement of the lifting component 13 can be further determined through the pressure monitoring of the pressure sensing module 223.

[0027] like Figures 4-6 As shown, the abutment assembly 23 includes an arc-shaped rod 231, a pressure plate 232, a connecting seat 233, and a connecting rod 234. The arc-shaped rod 231 slides vertically through the hook seat 21, with its bottom end extending out of the bottom surface of the hook seat 21 and its top end fixed to the pressure plate 232. A return spring 235 is provided between the pressure plate 232 and the top surface of the hook seat 21. When the bottom end of the arc-shaped rod 231 strikes the support plate 26 as the hook seat 21 descends, the arc-shaped rod 231 moves upward relative to the hook seat 21 and compresses the return spring 235, converting the rigid impact into an elastic buffer, absorbing the impact energy, and preventing damage to the transmission components due to impact overload. Specifically, the connecting seat 233 is fixed to one end of the telescopic shaft 221 located in the chamber 211. The two ends of the connecting rod 234 are hinged to the connecting seat 233 and the pressure plate 232, respectively. A limiting shaft 236 is threadedly installed on the inner side of the pressure plate 232. When the bow-shaped rod 231 is in its lowest position, the end of the limiting shaft 236 can be inserted into a preset limiting hole on the telescopic shaft 221 to assist in positioning. The abutment component 23 utilizes the inherent vertical stroke of the lifting component 13 when lowering the material frame 14, and mechanically pulls the telescopic shaft 221 back by contacting it with the bow-shaped rod 231. The disengagement is completed entirely by the movement of the equipment itself, without consuming additional energy.

[0028] like Figures 5-8As shown, the locking assembly 24 is installed on the outside of the hook seat 21 and includes a compression sleeve 241, a locking element 242, and a guide element 243. The compression sleeve 241 is fixedly sleeved on the part of the telescopic shaft 221 that extends out of the hook seat 21. The locking element 242 consists of 3-6 evenly distributed elastic blocks 2421 in a ring, with an arc-shaped locking block 2422 embedded in the inner side of each elastic block 2421. The outer side of the elastic block 2421 and the inner side of the compression sleeve 241 are both machined with pressure surfaces 2423 of the same taper. Under normal suspended conveying conditions, the compression sleeve 241 and the locking element 242 are in an interference fit, and the locking block 2422 grips the telescopic shaft 221; when the telescopic shaft 221 is pulled back, the compression sleeve 241 moves backward, and the pressure surface 2423 is in a clearance fit, thereby releasing the lock. The adaptive clamping and locking structure, combined with the mechanical locking of the switch assembly 25, provides dual protection, effectively preventing loosening, disengagement, and falling during heavy-load transport, while balancing lightweight operation with the safety of heavy-load work. Specifically, the guide component 243 includes a limiting seat 2431, a sliding rod 2432, and a buffer spring 2433; wherein, the limiting seat 2431 of the guide component 243 is fixed to the outer wall of the hook seat 21, one end of the sliding rod 2432 is fixed to the extrusion sleeve 241, and the other end slides through the limiting seat 2431, and a buffer spring 2433 is sleeved on the sliding rod 2432 to ensure the smooth movement of the extrusion sleeve 241. It should be noted that the locking assembly 24 has at least two guide members 243. During use, the guide members 243 provide protection, and the compression sleeve 241 is fixedly sleeved on the telescopic shaft 221. When the telescopic shaft 221 retracts or extends, the compression sleeve 241 moves accordingly. If there is only one guide member 243, the compression sleeve 241 may rotate slightly or wobble around the guide member 243 during movement. This wobble may cause the contact between the inner pressure surface 2423 of the compression sleeve 241 and the outer pressure surface 2423 of the elastic block 2421 to be disrupted. The contact is uneven, with one side having a large interference fit and the other side having a small interference fit; the clamping force of the locking block 2422 on the telescopic shaft 221 is unevenly distributed along the circumference, and local wear is aggravated; after long-term operation, the pressure surface 2423 may experience uneven wear, resulting in a decrease in locking force or unlocking jamming. Through the action of at least two guide members 243, multi-point constraints are formed in the circumference of the extrusion sleeve 241, effectively restricting the rotational freedom of the extrusion sleeve 241, so that it can only move along the axial direction, ensuring that the pressure surface 2423 always maintains a uniform annular contact with the elastic block 2421.

[0029] It should be noted that the number of locking components 24 can be increased to two, with the two locking components 24 located at the left and right ends of the telescopic shaft 221 respectively; in the single-sided locking scheme, the locking component 24 is only located at one end of the telescopic shaft 221. When the weight distribution of the marble slabs in the material frame 14 is uneven or when lateral impact occurs during conveying, the telescopic shaft 221 will be subjected to bending moment, resulting in uneven axial distribution of the contact pressure between the locking block 2422 and the telescopic shaft 221, which may lead to local excessive wear or a decrease in locking force. By having the two locking components 24 respectively hold the left and right ends of the telescopic shaft 221, a double-support point is formed; regardless of the load distribution, the telescopic shaft 221 remains straight and centered, the contact pressure between the locking block 2422 and the shaft surface is uniform, and the locking force is more stable and reliable; in addition, the double-sided locking means that each locking component 24 only needs to bear about half of the locking force requirement. Therefore, the size of a single locking component 24 can be appropriately reduced, such as by reducing the thickness of the elastic block 2421 or the width of the locking block 2422, to make the overall structure more compact, or by using a lower-cost friction material, while maintaining overall safety. Furthermore, the elastic block 2421 needs to undergo elastic deformation and radial contraction under external force, and return to its original shape after the external force disappears. This requires the material to have a high elastic limit and good fatigue resistance. Optionally, in dusty or humid environments, the base material of the telescopic shaft 221 can be made of 304 stainless steel, the locking block 2422 can be made of PEEK, and the surfaces of other parts can be treated with rust prevention.

[0030] like Figure 8 and Figure 9 As shown, the switch assembly 25 includes a mounting base 251, a magnetic rod 252, a plug rod 253, a second return spring 254, a support plate 26, a magnetic seat 27, and a magnetic block 28. The mounting base 251 is fixed to the bottom of the hook base 21. The magnetic rod 252 slides through the mounting base 251, with one end fixed to the plug rod 253 and the other end free. The second return spring 254 is sleeved on the magnetic rod 252 and located inside the mounting base 251. The support plate 26 is L-shaped or flat and is horizontally fixed to the side frame of the conveyor 15. The magnetic seat 27 is fixed to the top surface of the support plate 26, and a highly magnetic magnetic block 28 is embedded inside it. The magnetic poles of the magnetic rod 252 and the magnetic block 28 are opposite at their opposite ends. When the hook seat 21 descends to the unloading position, the magnetic rod 252 and the magnetic seat 27 are aligned, and the opposite magnetic poles push the magnetic rod 252, causing the insertion rod 253 to be pulled out of the insertion hole at the bottom of the bow-shaped rod 231. This magnetic triggering method requires no power or air source and works completely passively, further simplifying the structure and reducing weight. This invention automatically completes unlocking and unblocking through the mechanical stroke of the device's own descent and the opposite magnetic pole attraction, achieving efficient, lightweight, and highly safe heavy-duty suspended conveying.

[0031] Furthermore, the insertion rod 253 of the switch assembly 25 and the locking assembly 24 have a fixed timing relationship. The first lock is released by the magnetic pin, which must be completed before the bow-shaped rod 231 touches the support plate 26 to release the second lock. Because the magnetic base 27 is fixed at a certain height above the support plate 26, when the hook 21 descends, it first enters the magnetic range to pull the pin, and only after continuing to descend does it touch the support plate 26 to pull back the telescopic shaft 221. If the magnetic force fails, even if the bow-shaped rod 231 touches the support plate 26, it will be unable to move upwards because the insertion rod 253 has not been pulled out, thus locking the telescopic shaft 221 and preventing accidental disengagement. It should be noted that, due to the large weight of the Calacatta marble slabs, the overall load is high when combined with the material frame 14 and the hooking mechanism 2. Traditional equipment generally uses hydraulic or electric telescopic rods to drive the unlocking structure separately. This not only requires additional drive components, significantly increasing the overall weight and structural complexity of the equipment, but also increases the load pressure during sliding and lifting operations, exacerbating energy consumption and component wear. This equipment, through a magnetic passive unlocking and mechanical contact linkage unlocking structure, reduces the need for additional unlocking drive components. It can automatically unlock and unblock by relying on the mechanical stroke of the equipment's descent and the opposing magnetic attraction, thereby reducing the equipment's weight and lowering the load loss during guide rail sliding and lifting operations.

[0032] Combined with appendix Figures 1-9 The working principle of the above embodiments is as follows: In the initial state of the equipment, the guide rail seat 12 is slidably mounted on the guide rail frame 11, and can achieve horizontal displacement along the guide rail frame 11, driving the bottom overall lifting assembly 13, the hooking mechanism 2, and the locked material frame 14 to move horizontally, realizing the lateral conveying and alignment of marble slabs. The hydraulic telescopic rod 133 of the lifting assembly 13 is in the retracted state, the bottom plate 132 and the bottom hooking mechanism 2 are raised to the high position, the insertion rod 253 of the switch assembly 25 is inserted into and fixed the bow-shaped rod 231, so that the abutment assembly 23 and the telescopic shaft 221 are in the locked and fixed state, and the abutment seat 222 of the hook 22 is stably locked inside the abutment sliding opening of the material frame 14, realizing a reliable connection between the material frame 14 and the lifting assembly 13; When the equipment needs to transfer marble slabs, the guide rail seat 12 slides along the guide rail frame 11 to be directly above the conveyor 15. Then the hydraulic telescopic rod 133 extends and pushes the bottom plate 132 to move downward as a whole, which drives the bottom hooking mechanism 2 and the material frame 14 carrying the marble to descend synchronously. The limiting guide rod 134 slides through the top plate 131 to limit the vertical movement, ensuring the vertical stability of the bottom plate 132 during the lifting process and preventing the material frame 14 from shaking and causing the marble slabs to be bumped and damaged. As the hook 21 continues to move downward, the switch assembly 25 simultaneously triggers the unlocking action. The magnetic base 27 and the embedded magnetic block 28 form an attraction effect with the magnetic rod 252, causing the magnetic rod 252 to overcome the elastic force of the reset spring 254 and slide, causing the end plug rod 253 to disengage from the insertion limit of the bow rod 231 and release the locking state of the abutment assembly 23. As the hook seat 21 continues to move downward, the bottom end of the bow-shaped rod 231 contacts the upper surface of the support plate 26 and is subjected to force, forcing the bow-shaped rod 231 to slide upward relative to the hook seat 21, compressing the top return spring 235. During the displacement of the bow-shaped rod 231, the connecting seat 233 and the telescopic shaft 221 are pulled into the cavity 211 of the hook seat 21 through the hinged connecting rod 234, causing the abutment seat 222 to be pulled out from the abutment sliding opening of the material frame 14, completely releasing the snap-fit ​​relationship between the hook 22 and the material frame 14, and the material frame 14 is smoothly placed on the conveyor 15 table. After the material is unloaded, the hydraulic telescopic rod 133 retracts, driving the base plate 132 and the hooking mechanism 2 to move upward. The bow-shaped rod 231 is disengaged from the support plate 26 and resets under the action of the first reset spring 235. The magnetic rod 252 resets under the action of the second reset spring 254. The insertion rod 253 re-inserts and fixes the bow-shaped rod 231. The equipment returns to the initial locked state and waits for the next grabbing and conveying operation. At the same time, the locking component 24 locks and limits the displacement of the telescopic shaft 221 to ensure the stability of the equipment operation.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
