Description

Technical Field

[0001] This application relates to the technical field of safety protection for automated express logistics equipment, and in particular to an easily detachable safety net device for express sorting equipment. Background Technology

[0002] With the rapid development of the express delivery and logistics industry, automated sorting equipment has been widely used in major logistics hubs and sorting centers. This type of equipment typically achieves continuous transport of parcels by setting up densely arranged rollers 200 on a frame 100. To prevent small parcels from accidentally falling through the gaps between the rollers, a fixed protective net is usually installed at the bottom of the frame 100 to catch falling items, preventing them from directly hitting the ground and causing damage or becoming stuck inside the equipment.

[0003] However, in actual operation, small packages that fall onto the protective netting accumulate, requiring employees to clean or retrieve them regularly. Currently, the protective netting is typically fixed directly to the bottom of the frame 100 with multiple bolts, making disassembly cumbersome. Tools are needed to unscrew all the bolts one by one before the netting can be removed and the packages retrieved. This design leads to low operational efficiency, and during equipment pauses or when the machine is not completely stopped, employees often risk reaching their hands into the gaps between the still-operating rollers 200 to retrieve packages in order to save time, which greatly increases the risk of serious accidents such as hands being pinched or caught in the rollers 200.

[0004] Furthermore, existing protective netting is a fixed, integral structure, making it impossible to quickly open or flexibly adjust individual sections. This not only increases the difficulty of daily maintenance but also hinders the convenience of partial inspection and cleaning of the equipment. Although the industry's safety requirements for sorting equipment are increasing, there is still a lack of improved designs that balance convenience and safety in protective netting. This makes it difficult to effectively guide employees to operate in a standardized manner and reduce safety risks while ensuring protective functions. Utility Model Content

[0005] In view of the above-mentioned prior art, and to solve the problems of inconvenient disassembly of protective nets and high risk of employee violations, this application provides an easily disassembled safety protective net device for express sorting equipment.

[0006] This application provides an easily detachable safety net device for express sorting equipment, which adopts the following technical solution: A removable safety net device for express sorting equipment includes a mounting frame, in which a safety net is disposed. The mounting frame is located below a roller, and a connecting component for detachable connection with a frame is disposed on the mounting frame. The connecting component includes a pin and a plug-in cylinder. The plug-in cylinder is fixedly mounted on the frame, and the pin is slidably mounted on the mounting frame. The pin is plugged into and fixedly connected to the plug-in cylinder.

[0007] By adopting the above technical solution, the sliding pin shaft enables quick insertion and separation from the fixed plug tube, replacing the traditional bolt connection method. This makes the installation and removal of the protective netting without the use of any tools, and the operation is simple and quick, fundamentally avoiding the risk of employees violating regulations due to the cumbersome disassembly process.

[0008] Preferably, the connecting components are provided at both ends of the mounting frame along its length.

[0009] By adopting the above technical solution, connecting components are symmetrically set at both ends of the mounting frame, which can ensure that the mounting frame and the frame form a stable connection at two or more points, improve the stability and load uniformity of the overall structure, and prevent shaking or tilting that may occur with a single-point connection.

[0010] Preferably, the mounting frame is provided with a mounting base, and the mounting base is provided with two connecting plates. The two connecting plates are provided with sliding holes with the same axis, and the pin is slidably disposed in the sliding holes of the two connecting plates.

[0011] By adopting the above technical solution, the mounting base and two connecting plates with sliding holes provide precise and stable sliding guidance for the pin, ensuring that the pin can smoothly extend or retract along a straight line and accurately align and insert into the connector, thereby improving the reliability of the connection and the accuracy of repeated operations.

[0012] Preferably, the pin is provided with a limiting part, which is located between the two connecting plates.

[0013] By adopting the above technical solution, the setting of the limiting part can limit the axial movement of the pin in the sliding hole, and prevent it from sliding excessively or completely dislodging when not in operation.

[0014] Preferably, both the mounting frame and the machine frame are provided with threaded posts, and the mounting base has through holes for fitting the threaded posts of the mounting frame and is locked in place by means of nuts; the plug-in cylinder is integrally formed with a mounting plate, and the mounting plate has through holes for fitting the threaded posts of the machine frame and is locked in place by means of nuts.

[0015] By adopting the above technical solution, the various components (mounting base, plug-in cylinder) are fixed by using threaded columns, through holes and nuts. The structure is simple, the installation is firm and easy to disassemble and replace, which is conducive to the modular design and maintenance of the equipment.

[0016] Preferably, the connecting assembly further includes a chain, with connecting plates at both ends of the chain. The connecting plates have through holes. One end of the chain is fitted onto a threaded post on the mounting frame through the through hole on the connecting plate and locked in place by a nut. The other end of the chain is fitted onto a threaded post on the frame through the through hole on another connecting plate and locked in place by a nut.

[0017] By adopting the above technical solution, the chain, as an independent safety mechanism, flexibly connects the mounting frame to the machine frame at all times, in addition to the pin connection. During disassembly, even if the pin is completely disengaged, the chain can effectively prevent the mounting frame from accidentally falling, greatly improving the safety of maintenance operations.

[0018] Preferably, a limiting plate is provided between the two connecting plates, with both ends of the limiting plate facing the two connecting plates along the length direction, and a gap is left between the end of the limiting plate and the connecting plate; when the pin is inserted into the plug cylinder, the pin is rotated through the limiting part, so that the limiting part rotates into the gap between the limiting plate and the connecting plate and abuts against the end of the limiting plate.

[0019] By adopting the above technical solution, the limiting part is engaged in the gap formed by the limiting plate and the connecting plate by rotating the pin, forming a reliable mechanical lock. This structure can effectively resist vibration and accidental contact during equipment operation, prevent the pin from accidentally slipping out of the insertion cylinder, and ensure the long-term stability of the connection.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. By using a sliding plug-in connection component to replace traditional bolt fixing, operators can quickly install and dismantle the protective net without tools, significantly shortening maintenance time and improving work efficiency; 2. The rotatable locking pin structure prevents the connection from loosening due to vibration; at the same time, the independent chain tether design provides fall protection during disassembly, and the dual safety guarantee effectively eliminates the motivation of employees to operate in violation of regulations and potential safety risks; 3. The main connecting components adopt standardized design (such as threaded columns and nuts), the guiding and locking mechanisms are simple and effective, the overall structure is stable, easy to process and manufacture, and supports modular replacement, which reduces manufacturing and long-term maintenance costs.

Detailed Implementation

[0023] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0024] This application discloses an easily detachable safety net device for express sorting equipment.

[0025] Reference Figure 1 and Figure 2 A removable safety net device for express sorting equipment includes a mounting frame 1 and connecting components 2 located at both ends of the mounting frame 1 along its length. A protective net 11 is installed inside the mounting frame 1. The mounting frame 1 is located below the roller 200 and is detachably connected to the frame 100 through the connecting components 2.

[0026] Reference Figure 3 The connecting component 2 includes two pins 21 and a plug-in sleeve 22. The plug-in sleeve 22 has an integrally formed mounting plate 221. The side wall of the frame 100 is provided with a threaded post. The mounting plate 221 has a through hole. The mounting plate 221 is sleeved on the threaded post of the frame 100 through the through hole and locked by the thread. The two pins 21 are slidably mounted on the mounting frame 1. The mounting frame 1 has a mounting seat 3 with a number corresponding to the two pins 21 fixedly mounted on the peripheral wall. The mounting seat 3 has two connecting plates 4 fixedly mounted on it. The two connecting plates 4 have sliding holes 41 located on the same axis. The pins 21 pass through and slide in the sliding holes 41 of the two connecting plates 4 and are plugged into and fixedly mounted on the plug-in sleeve 22 on the frame 100.

[0027] The mounting frame 1 also has threaded posts on its peripheral wall for fixing mounting bases 3. The mounting base 3 has through holes for fitting onto the threaded posts of the mounting frame 1 and is locked in place by nuts. The connecting assembly 2 also includes two chains 23, which are positioned opposite to the two mounting bases 3. Each end of the chain 23 has a connecting piece 231 with through holes. One end of the chain 23 is fitted onto the threaded post of the mounting frame 1 via the connecting piece 231 and locked in place with the same nut as the mounting base 3. The other end of the chain 23 is fitted onto the threaded post of the frame 100 via another connecting piece 231 and locked in place with the same nut as the mounting piece 221 of the insert sleeve 22.

[0028] When the protective netting 11 needs to be disassembled for cleaning or maintenance, the operator can manually pull the pin 21 outwards to disengage it from the connector 22, thus separating the mounting frame 1 along with the protective netting 11 from the frame 100. During this process, the chain 23 remains connected between the mounting frame 1 and the frame 100, preventing the mounting frame 1 from accidentally falling and ensuring operational safety. The entire process requires no tools, achieving quick and safe disassembly.

[0029] A limiting part 211 is provided on the pin 21. When the pin 21 passes through the sliding hole 41 of the two connecting plates 4, the limiting part 211 is located between the two connecting plates 4. The mounting base 3 is fixedly installed between the two connecting plates 4 with a limiting plate 5. The two ends of the limiting plate 5 along the length direction are respectively set towards the two connecting plates 4, and a gap is left between them.

[0030] When the pin 21 is inserted into the plug tube 22, the limiting part 211 abuts against the connecting plate 4 on the side near the plug tube 22. Then, by operating the limiting part 211 to rotate the pin 21, the limiting part 211 rotates into the gap between the connecting plate 4 and the limiting plate 5 and abuts against the end of the limiting plate 5, thereby preventing the pin 21 from axially retracting along the sliding hole 41 and firmly locking the pin 21 in the insertion fixed position to prevent it from coming out due to equipment vibration or accidental contact.

[0031] The implementation principle of this application embodiment is as follows: the insertion and engagement between the slidable pin 21 set on the mounting frame 1 and the plug-in cylinder 22 fixed on the frame 100 enables quick tool-free disassembly and assembly of the protective net 11 device; the limiting part 211 on the pin 21 rotates and locks into the gap between the connecting plate 4 and the limiting plate 5 after insertion, forming a mechanical lock, effectively preventing vibration and loosening during equipment operation; at the same time, the independently set chain 23, which is fixed at both ends to the mounting frame 1 and the frame 100 respectively, provides fall protection during disassembly, thereby eliminating operational safety hazards by improving maintenance convenience and achieving a unity of safety protection and convenient maintenance.

[0032] 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.
