Description

Technical Field

[0001] This utility model relates to the field of transportation equipment technology, and in particular to a spiral chute buffer device for a baggage system. Background Technology

[0002] Currently, with the rapid expansion of my country's civil aviation transportation scale and the increasing number of air travelers, high-quality development of civil aviation has become the most fundamental requirement. The effectiveness of high-quality development in civil aviation is reflected in its comprehensive benefits, including a strong safety baseline, high operational efficiency, excellent service quality, good economic benefits, and strong development potential. Among these, operational efficiency is a comprehensive reflection of high-quality development in civil aviation, service quality embodies its social value, and economic benefits demonstrate its strength.

[0003] For airports, facing the high pressure of passenger throughput, the operational efficiency of equipment, baggage sorting speed, and passenger service satisfaction indicators are particularly important. Currently, most airports handling tens of millions of passengers have introduced automated sorting systems and installed spiral chutes to improve sorting efficiency. While spiral chutes meet the demand for rapid sorting, they also increase the risk of baggage damage and passenger service complaints.

[0004] Existing technologies, in order to overcome the high baggage breakage rate of spiral chutes, have adopted measures such as simply adding anti-slip belts, adjusting the radius of the chute, and adding protrusions to the inner surface of the chute. However, these improvements are monotonous, costly, and ineffective. Due to the inherent mechanical characteristics of spiral chutes, baggage transported via this method falls at high speeds and is highly susceptible to breakage. Currently, airports using spiral chutes generally employ relatively simple deceleration methods, which cannot ensure the smooth transport of baggage of different shapes and postures, and lack effective solutions to address frictional changes caused by climate change. This hinders the achievement of the strategic goal of high-quality airport development.

[0005] Therefore, it is evident that whether an improved spiral chute buffer device for baggage systems can be provided based on the shortcomings of existing technologies to solve the problems of high baggage damage rate, high equipment failure rate, and inability to dynamically adapt to seasonal changes has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to overcome the aforementioned shortcomings in the existing technology and provide a structurally improved spiral chute buffer device for a baggage system. Structural improvements have been made to three key nodes: baggage loading, transport, and smooth unloading. By increasing sliding friction, reducing the downward speed, and smoothing the unloading path, the damage rate of baggage is effectively reduced. Furthermore, by introducing a dynamic adjustment factor, the device can ensure smooth baggage transport in different seasons. Specifically, the technical solution includes the following:

[0007] A baggage system spiral chute buffer device includes multiple anti-slip belts and a buffer lead curtain assembly disposed on the spiral chute. The multiple anti-slip belts are spaced apart on the spiral chute, and the buffer lead curtain assembly is disposed on the spiral chute near the baggage entrance. The buffer lead curtain assembly includes a bracket, a lead curtain suspended on the bracket, and a counterweight bag detachably connected to the lower part of the lead curtain.

[0008] Furthermore, the multiple anti-slip belts include a first anti-slip belt, a second anti-slip belt, and a third anti-slip belt.

[0009] Furthermore, the spiral chute includes an inlet section, a transport section, and an outlet section connected in sequence, wherein the inlet section is provided with a first anti-slip belt and the buffer lead curtain assembly.

[0010] Furthermore, the first anti-slip belt is installed at the baggage entrance, with one end near the baggage entrance positioned between the baggage sorting exit and the spiral chute entrance.

[0011] Furthermore, a second anti-slip belt is provided on the transport section, and a metal pressure strip is fixedly connected to the side of the second anti-slip belt near the baggage entrance.

[0012] Furthermore, the buffer device also includes a buffer belt, which is disposed on the inner wall of the side plate of the transport section in an arc shape with the column as the center, and the buffer belt is filled with a filling material.

[0013] Furthermore, the export section is provided with a third anti-slip belt, and a metal pressure strip is fixedly connected to the side of the third anti-slip belt near the luggage entrance.

[0014] Furthermore, the buffer device also includes an extension section connected to the baggage outlet of the outlet section.

[0015] Furthermore, the extension section is inclined, with one end connected to the outlet of the lead-out section and the other end connected to the ground.

[0016] Furthermore, the buffer device also includes a smooth transition side plate, which is disposed on the inner wall of the side plate of the lead-out section in an arc shape with the column as the center.

[0017] Furthermore, the bracket is U-shaped, with one end fixedly connected to the column supporting the spiral groove and the other end fixedly connected to the spiral groove. The lead curtain includes multiple strips of lead arranged in a row, and the counterweight bag is detachably connected to the lower part of the lead strips.

[0018] One or more technical solutions provided in this utility model have at least the following technical effects or advantages:

[0019] 1. In the spiral chute buffer device of this utility model baggage system, multiple anti-slip belts are set to increase sliding friction and reduce the downward speed of the baggage. At the same time, the use of a buffer lead curtain assembly further reduces the downward speed of the baggage. Through the detachable weight bag, the filling material, weight, and size of the weight bag can be selected according to different seasonal changes and the characteristics of different baggage. It can dynamically adapt to seasonal changes to control the buffering force on the baggage, slow down the downward speed of the baggage, and reduce the risk of damage to the baggage.

[0020] 2. In the spiral chute buffer device of this utility model's baggage system, a three-section anti-slip belt is set in the spiral chute, namely the inlet section, the transport section, and the outlet section. This ensures that the baggage is buffered during the inlet, transport, and outlet stages, reducing the damage rate caused by impact. Furthermore, the first anti-slip belt in the inlet section is located at the baggage entrance, effectively reducing the initial velocity of the baggage as it slides down, thus reducing the risk of damage. The anti-slip belts in the transport and outlet sections are fixed with riveted metal strips, allowing the baggage to slide smoothly into the anti-slip belt section and preventing the baggage from getting stuck or jammed.

[0021] 3. In the spiral chute buffer device of the baggage system of this utility model, in order to reduce the initial velocity impact when the baggage goes down the sorting machine, a buffer belt with filling material is added at the bend impact point at the exit of the sorting machine. The filling material can be sponge foam, which avoids the impact during the rotation and sliding of the baggage and reduces the risk of damage to the baggage.

[0022] 4. In the spiral chute buffer device of the luggage system of this utility model, since the luggage accelerates during its descent, it will impact the side plate at the exit of the spiral chute. By setting a smooth transition side plate and an extension section, the luggage can be buffered and slide out, reducing the impact of the luggage at the exit of the spiral chute.

[0023] 5. In the spiral chute buffer device of the luggage system of this utility model, in order to increase the stability of the buffer lead curtain assembly, one end of the bracket is fixed to the column and the other end is fixed to the joint of two adjacent transport plates of the spiral chute. The lead curtain is suspended on the crossbar of the bracket, which greatly improves the stability of the bracket and makes the buffer lead curtain assembly more stable during use.

[0032] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0033] Example:

[0034] A spiral chute buffer device for a baggage system, such as Figure 1 As shown, the system includes multiple anti-slip belts and a buffer lead curtain assembly mounted on the spiral chute 2. The multiple anti-slip belts are spaced apart on the spiral chute, increasing sliding friction and reducing the speed at which luggage slides down. The number of anti-slip belts can be selected based on the length and material of the spiral chute, specifically from 2 to 15. More anti-slip belts can be used when greater buffering force is needed, and fewer can be used when less buffering force is required. More preferably, the anti-slip belts include a first anti-slip belt 6, a second anti-slip belt 7, and a third anti-slip belt 10. The multiple anti-slip belts work in conjunction with the buffer lead curtain assembly to further reduce the speed at which luggage slides down. The buffer lead curtain assembly is located near the luggage entrance of the spiral chute 2 and includes a bracket 3, a lead curtain 4 suspended on the bracket 3, and a counterweight bag 5 detachably connected to the lower part of the lead curtain 4. The detachable weight bag 5 allows for selection of filling material, filling weight, and weight bag 5 size according to different seasonal changes and the characteristics of different luggage. It can dynamically adapt to seasonal changes to control the cushioning force on luggage, slow down the luggage's sliding speed, and reduce the risk of luggage damage.

[0035] More preferably, the spiral chute 2 includes an inlet section, a transport section, and an outlet section connected in sequence. The inlet section is provided with a first anti-slip belt 6 and the buffer lead curtain assembly from top to bottom. The bracket 3 is U-shaped, with one end fixedly connected to the column 1 supporting the spiral chute and the other end fixedly connected to the spiral chute 2. The lead curtain 4 includes multiple strip-shaped lead strips arranged in a row, which are suspended from the crossbar of the bracket 3. Multiple counterweight bags 5 are detachably connected to the lower part of each lead strip. The number of lead strips can be selected based on the width of the spiral chute and the usage requirements. The number of counterweight bags connected to the lower part of the lead strips can also be selected based on the actual luggage cushioning requirements. If a larger cushioning force is required, a heavier counterweight bag 5 can be connected to the lower part of each lead strip. If a smaller cushioning force is required, a lighter counterweight bag 5 can be connected to the lower part of each lead strip, or a counterweight bag 5 can be connected every 1, 2, or 3 lead strips. That is, it is not necessary to connect a counterweight bag 5 to every lead strip. The counterweight bags 5 are connected to the lead straps at intervals to generate balanced buffer resistance. More preferably, one end of the bracket 3 is fixed to the column 1, and the other end is fixed to the joint between two adjacent transport plates of the spiral chute 2, greatly improving the stability of the bracket 3 and making the buffer lead curtain assembly more stable during use. Even more preferably, the end of the first anti-slip belt 6 near the baggage inlet is positioned between the baggage sorting outlet and the inlet of the spiral chute 2. This allows baggage to slide smoothly into the anti-slip belt section, preventing baggage from getting stuck or jammed.

[0036] Further preferred, such as Figure 1 As shown, a second anti-slip belt 7 is provided on the transport section. A metal pressure strip 8 is fixedly connected to the side of the second anti-slip belt 7 near the baggage entrance. The buffer device also includes a buffer belt 9. The buffer belt is set on the inner wall of the side plate of the transport section in an arc shape with the column 1 as the center. The buffer belt 9 is filled with a filling material, which can be sponge foam, to avoid impact during the rotation and sliding of the baggage and reduce the risk of damage to the baggage.

[0037] Further preferred, such as Figure 2As shown, the exit section is equipped with a third anti-slip belt 10, and a metal pressure strip 8 is fixedly connected to the side of the third anti-slip belt 10 near the baggage entrance. The metal pressure strips 8 on both the second anti-slip belt 7 and the third anti-slip belt 10 are fixed to the inner wall of the spiral chute 2 by riveting. The spiral chute 2 is equipped with three sections of anti-slip belts: an inlet section, a transport section, and an exit section, so that baggage is buffered during the inlet, transport, and exit stages, reducing the damage rate caused by impact. Furthermore, the first anti-slip belt 6 of the inlet section is located at the baggage entrance, effectively reducing the initial velocity of the baggage as it slides down, thus reducing the risk of damage. The anti-slip belts of the transport and exit sections are fixed by riveted metal pressure strips 8, allowing baggage to slide smoothly into the anti-slip belt section and preventing baggage from getting stuck or jammed. More preferably, the buffer device also includes an extension section 11, which is connected to the baggage exit of the exit section. The extension section 11 is inclined, with one end connected to the exit of the exit section and the other end connected to the ground. The buffer device also includes a smooth transition side plate 12, which is disposed on the inner wall of the side plate of the exit section, forming an arc shape with the column as the center. More preferably, the smooth transition side plate 12 is made of a painted plate of the same material as the spiral chute 2, forming a smooth arc transition, and is welded to the inner wall of the smooth side plate centered on the central column 1 of the spiral chute 2. By providing the smooth transition side plate 12 and the extension section 11, the luggage can slide out with cushioning, reducing the impact of the luggage at the exit of the spiral chute 2.

[0038] A luggage spiral transport system includes a column 1 and a spiral chute 2 arranged around the column 1, wherein the spiral chute 2 is provided with the aforementioned buffer device.

[0039] In summary, the spiral chute buffer device for a baggage system protected by this utility model has low cost, low failure rate, and significant effect in reducing damage rate. By adjusting the weight and size of the counterweight bag 5, it can dynamically adapt to seasonal changes to control the buffering force on the baggage, slow down the baggage's descent speed, and reduce the risk of baggage damage.
