Description

Technical Field

[0001] This utility model relates to the field of emergency maintenance technology for conveying machinery, and more specifically, to an emergency device for single-sided operation of a double narrow belt conveyor. Background Technology

[0002] With the rapid development of the air transport industry, the operational efficiency and reliability of airport baggage handling systems are becoming increasingly important. As a key piece of equipment in automated baggage sorting systems, dual narrow-belt conveyors typically use two synchronously running narrow belts to drive the cargo cart forward, achieving efficient baggage transfer. However, in actual operation, due to factors such as long-term load, wear, aging, or accidental breakage of the belts, single-sided belt failure often occurs.

[0003] Currently, the common emergency handling method for a broken belt on one side of a twin-narrow-belt conveyor is to directly remove the broken belt and rely solely on the normal belt on the other side to continue driving the trolley. While this method can temporarily restore system operation, it has significant drawbacks: the normal belt must bear the entire driving load, while the bottom of the trolley on the other side experiences sliding friction with the frame, leading to increased running resistance, higher motor load, and increased energy consumption. It also easily causes overload, accelerated wear, and even secondary breakage of the normal belt. Furthermore, sliding friction can cause the trolley's trajectory to deviate, easily leading to baggage blockages, jams, and other malfunctions, severely impacting baggage handling efficiency and system reliability. Utility Model Content

[0004] The purpose of this utility model is to provide an emergency device for single-sided operation of a double narrow belt conveyor, which aims to solve the problems of high running resistance, high energy consumption, easy overload and wear of the normal belt, and trolley trajectory deviation caused by relying on only one side belt to run after the single-sided belt of the double narrow belt conveyor breaks.

[0005] This utility model is achieved through the following technical solution:

[0006] An emergency device for single-sided operation of a double narrow belt conveyor includes: a main body and a rotating component. The main body is provided with a mounting part, which is adapted to the belt frame of the double narrow belt conveyor. The rotating component is disposed on the main body and makes rolling contact with the belt of the double narrow belt conveyor.

[0007] Optionally, the mounting portion is located in the middle of the main body.

[0008] Optionally, there are several rotating components, and the several rotating components are symmetrically arranged on both sides of the main body with respect to the center line of the mounting part.

[0009] Optionally, there are at least two rotating components, and at least two rotating components are disposed on both sides of the main body.

[0010] Optionally, the main body includes a horizontally arranged cross plate and two vertically arranged vertical plates, the upper ends of the two vertical plates being connected to the two ends of the cross plate respectively, and the mounting part being formed between the two vertical plates.

[0011] Optionally, the mounting part is in the shape of a door frame.

[0012] Optionally, the rotating assembly includes a roller and a shaft, the roller being rotatably mounted on the shaft via bearings, and both ends of the shaft being fixed to the main body.

[0013] Optionally, the outer peripheral surface of the roller is provided with an anti-slip layer or friction texture.

[0014] Optionally, it also includes a limiting component, wherein the mounting part is provided with a mounting hole adapted to the belt frame, and the limiting component passes through the mounting hole and is connected to the mounting part.

[0015] Optionally, the limiting assembly includes a fastening bolt and an anti-loosening washer, the fastening bolt passing through the mounting hole and the anti-loosening washer engaging with a threaded hole on the belt frame.

[0016] The technical solution of this utility model has at least the following advantages and beneficial effects:

[0017] By setting a rotating component that rolls into contact with the belt, the original sliding friction between the failed side trolley and the frame is replaced, which greatly reduces the running resistance, thereby reducing the motor load and effectively reducing system energy consumption.

[0018] It distributes the drive load, avoiding the risk of overload, accelerated wear or breakage that would occur if the normal side belt bore the entire load alone, thus improving the reliability and safety of the system in emergency situations.

[0019] The rolling contact method ensures that the trolley can maintain a smooth straight-line operation even under single-sided drive, effectively preventing malfunctions such as trolley deviation, jamming, or bag blockage caused by uneven friction, and maintaining the sorting efficiency and smooth operation of the baggage handling system.

[0020] The main body of the device is equipped with an installation part that is directly compatible with the conveyor frame, which can be quickly installed without complicated debugging or extensive modifications. It can be deployed rapidly after the belt breaks, minimizing system downtime. Attached Figure Description

[0027] The following is a detailed description of the embodiments, in conjunction with the accompanying drawings.

[0028] Reference Figure 1 , Figure 2 An emergency device for single-sided operation of a double narrow belt conveyor includes: a main body 1 and a rotating assembly 2. The main body 1 is provided with a mounting part, which is adapted to the belt frame 4 of the double narrow belt conveyor. The rotating assembly 2 is mounted on the main body 1 and makes rolling contact with the belt 5 of the double narrow belt conveyor. The main body 1 can be machined from metal (such as aluminum alloy or steel) profiles or sheet metal parts. The mounting part can be directly clamped to the beam or a specific mounting edge of the belt frame 4. This method does not require modification of the existing frame and has the fastest installation speed. The rotating assembly 2 includes rollers and a rotating shaft. The rollers are rotatably mounted on the rotating shaft through bearings, and the rotating shaft is connected to the main body 1 through bearing seats. Standard mounting holes or threaded holes are pre-drilled in the belt frame 4, and the mounting part of the main body 1 is fixed to it with bolts. After installation, it is as follows: Figure 3 As shown. The emergency procedure is as follows:

[0029] Reference Figure 5 When the system detects or manually discovers a belt breakage on one side, the machine should be stopped immediately. The operator should remove the broken belt 502 and transport the emergency device to the corresponding position on the side of the broken belt. The main body 1 should be installed on the belt frame 4 via its mounting part. The rollers of the rotating component 2 should maintain appropriate contact pressure with the lower surface of the normally operating belt 5. The system should be started, and the normal belt 501 should begin running. At this time, the part of the cargo trolley 6 that originally slid against the frame is now supported and guided smoothly by the rotating rollers in conjunction with the normal belt 501. The number of emergency devices can be installed as needed according to the site conditions. When the belt 5 is long, multiple emergency devices can be installed at intervals. The interval between adjacent emergency devices should be less than the length of the cargo trolley 6. Figure 4As shown.

[0030] In some embodiments, the mounting part is located in the middle of the main body 1. This ensures that the mounting point is located in the middle of the main body 1, and the centered mounting point makes the pressure of the rollers on the belt on both sides completely symmetrical and equal. This ensures that when the cargo trolley 6 passes, the supporting force and guiding force on its left and right sides are balanced, effectively preventing the trolley from deviating or getting stuck due to uneven resistance on both sides, and greatly improving the smoothness and reliability of operation.

[0031] In some embodiments, there are several rotating components 2, with the mounting portion located in the middle of the main body 1. These rotating components 2 are symmetrically arranged on both sides of the main body 1 about the vertical center line of the mounting portion. This symmetrical arrangement ensures that the pressure distribution of the rollers on the belt is uniform, resulting in a complete balance between the supporting and guiding forces on the left and right sides of the cargo trolley. This effectively avoids problems such as trolley trajectory deviation, jamming, or bag blockage caused by excessive resistance on one side, significantly improving operational stability and reliability.

[0032] In some embodiments, there are at least two rotating components 2, and at least two rotating components 2 are disposed on both sides of the main body 1. (Refer to...) Figure 4 , Figure 5 The emergency device is installed at the location where the broken belt 502 has been removed. Multiple rollers support the weight of the trolley, converting the original sliding friction into rolling friction, which greatly reduces running resistance, reduces motor load and system energy consumption, and avoids overloading of the normal side belt.

[0033] In some embodiments, the main body 1 includes a horizontally arranged cross plate and two vertically arranged vertical plates. The upper ends of the two vertical plates are respectively connected to the two ends of the cross plate, and a mounting portion is formed between the two vertical plates, constituting a metal frame. The horizontal cross plate can effectively bear the vertical load from the cargo trolley and distribute it evenly to the vertical plates on both sides, avoiding stress concentration. This structure can resist the vibration and impact that may be generated during belt operation, ensuring that the emergency device does not deform or loosen under long-term heavy-load operation, providing a solid and reliable mechanical foundation for the entire emergency system. The "mounting portion" space naturally formed between the two vertical plates is adapted to the beams or mounting edges of the belt frame 4. This design allows the device to be directly and accurately fitted or locked onto the predetermined position of the belt frame 4 like a "clamp" or "sleeve".

[0034] In some embodiments, the mounting section is shaped like a portal frame. This portal frame structure allows for an efficient and stable fit with the beams or mounting edges of the conveyor belt frame. Its rigid frame design can evenly distribute vertical and lateral loads from the trolley 6, effectively dispersing stress and preventing localized deformation. Simultaneously, the portal frame-like enclosure provides natural positioning and clamping space, allowing for direct nesting or clamping onto the belt frame 4 during installation without additional complex adjustments. This significantly improves installation speed and accuracy, ensuring the emergency device maintains a secure connection under long-term vibration and impact conditions, thereby guaranteeing the stability and reliability of the system operation.

[0035] In some embodiments, the outer peripheral surface of the roller is provided with an anti-slip layer or friction texture. The anti-slip layer (such as polyurethane, rubber coating) or friction texture (such as diamond pattern, knurling) effectively increases the coefficient of friction between the roller and the belt contact surface, ensuring that the belt can efficiently drive the roller to rotate through friction during normal operation, avoiding slippage and free spin, thereby ensuring the reliability and continuity of power transmission.

[0036] In some embodiments, a limiting component 3 is also included. The mounting part is provided with a mounting hole adapted to the belt frame 4, and the limiting component 3 passes through the mounting hole and is connected to the mounting part. The limiting component 3 forms a mechanical interlock with the belt frame 4 through the mounting hole, which can effectively resist lateral or longitudinal displacement caused by vibration, impact or belt tension changes during equipment operation, ensuring that the emergency device is always in the preset ideal position and avoiding positioning deviation or failure due to loosening.

[0037] In some embodiments, the limiting component 3 includes a fastening bolt and an anti-loosening washer. The fastening bolt passes through a mounting hole and the anti-loosening washer, engaging with a threaded hole on the belt frame 4. The engagement of the fastening bolt with the pre-drilled threaded hole on the belt frame 4 forms a rigid, mechanically interlocked connection, greatly enhancing the connection strength between the emergency device and the main frame. This ensures that the device will not shift or fall off under harsh working conditions, guaranteeing the long-term stability of emergency operation. The anti-loosening washer effectively prevents the bolt from loosening under long-term vibration, solving the problem of potential failure of ordinary bolt connections in such environments. This further enhances the reliability and safety of the entire emergency device connection, avoiding the maintenance problem of frequent shutdowns for tightening due to loose connections.
