Description

Technical Field

[0001] This application relates to the technical field of logistics conveying equipment, and in particular to a pinch-proof folding tipping bucket safety operating platform for telescopic conveyors in express delivery distribution centers. Background Technology

[0002] Currently, in the loading and unloading scenarios of express delivery distribution centers, the telescopic conveyor is the core conveying equipment connecting the trucks and the sorting line. The core transmission structure of the telescopic conveyor includes rollers and belts, with the entire belt wrapped around the outside of multiple rollers in a circular pattern. During operation, the operator places the goods from the truck at the front end of the telescopic conveyor. The motor drives the rollers to rotate, and the friction between the rollers and the belt drives the entire belt to circulate, achieving continuous and efficient transport of goods.

[0003] Due to the limitations of the telescopic structure design, there is always a gap between the belt at the front end of the telescopic conveyor in the express delivery distribution center and the ground. When the distribution center is busy, operators need to frequently walk around the telescopic conveyor, move goods, or adjust their positions. Their attention is easily distracted, and their feet are very likely to accidentally step into the gap. Once this happens, the running belt will generate continuous traction, which may further pull the foot in, causing pinching, squeezing, or even fractures, directly threatening the operator's personal safety.

[0004] In response to the aforementioned technologies, some distribution centers have tried different types of basic protective measures. Some distribution centers remind employees by drawing safety warning lines on the ground or placing warning signs. However, these measures rely entirely on the safety awareness and self-discipline of the operators. During peak distribution periods or when personnel are fatigued, the warning effect is greatly weakened and cannot fundamentally eliminate the risks. Other distribution centers have built fixed guardrails or platforms at the front of the telescopic conveyor belts to prevent operators from contacting ground gaps. However, fixed guardrails or platforms restrict the telescopic range and movement path of the equipment, seriously affecting operational flexibility and loading and unloading efficiency. Utility Model Content

[0005] To effectively ensure the safety of operators without affecting the normal operating efficiency and flexibility of the telescopic conveyor in the express delivery distribution center, this application provides a folding bucket safety operating platform for the telescopic conveyor in the express delivery distribution center that prevents pinching injuries.

[0006] This application provides a pinch-resistant, folding tipping bucket safety operating platform for telescopic conveyors in express delivery distribution centers, employing the following technical solution: A pinch-resistant folding tipping bucket safety operating platform for a telescopic conveyor in an express delivery distribution center includes a fixed bracket, a fixed baffle, a platform plate, a horizontal locking component, and a vertical locking structure. The fixed bracket is located at the end of the telescopic conveyor frame, the fixed baffle is fixedly installed on the fixed bracket, the platform plate is hinged to the bottom of the fixed baffle, and the fixed baffle is located on the side of the platform plate closer to the telescopic conveyor frame. The horizontal locking component and the vertical locking structure are both disposed between the platform plate and the fixed baffle.

[0007] By adopting the above technical solution, the platform plate can rotate relative to the fixed baffle around the hinge axis, realizing the switching between two states: horizontal operation and vertical storage. When horizontally deployed, the horizontal locking component locks the platform plate, and the fixed baffle and the platform plate together isolate the gap at the end of the telescopic frame, preventing the operator's feet from accidentally entering or goods from falling, thus ensuring operational safety. When vertically stored, the vertical locking structure fixes the platform plate, making it close to the fixed baffle, without occupying extra space, and without interfering with the movement of the telescopic machine and the passage of goods, thus balancing safety and equipment flexibility.

[0008] Preferably, mounting plates are fixedly connected to both sides of the fixed bracket, and the mounting plates are fixedly connected to the telescopic frame body by bolts. The fixed baffle is disposed between the two mounting plates, and the fixed bracket, the fixed baffle and the mounting plates are integrally formed.

[0009] By adopting the above technical solution, the integrated fixed bracket, fixed baffle and mounting plate have strong overall structure, no weak points in welding, and can withstand the force when the platform plate is flipped and loaded; the mounting plate is fastened to the telescopic frame with bolts to ensure the overall installation of the platform is stable, avoid loosening after long-term use, and facilitate later disassembly and maintenance.

[0010] Preferably, the platform plate is hinged to the bottom of the fixed baffle via heavy-duty hinges.

[0011] By adopting the above technical solutions, heavy-duty hinges have high load-bearing capacity and can support the platform plate to rotate flexibly around the hinge axis, realizing a smooth switch between horizontal working and vertical storage states. In addition, the connection structure of heavy-duty hinges is highly durable and can adapt to the frequent operation needs of express delivery distribution centers.

[0012] Preferably, the platform plate is made of steel plate with diamond anti-slip pattern, the platform plate is 1cm thick, and the platform plate has a length and width of 1200mm×400mm; the side of the platform plate used to support the operator is covered with an anti-slip mat.

[0013] By adopting the above technical solution, the 1cm thick diamond-patterned anti-slip steel plate has sufficient strength and rigidity to support the weight of the operator and the goods being delivered. The diamond pattern on the surface increases friction, and when combined with the anti-slip mat, it further enhances the anti-slip effect, preventing the operator from slipping while standing or placing goods. At the same time, the anti-slip mat can also improve standing comfort and reduce fatigue during long-term work.

[0014] Preferably, the platform plate is provided with guardrails at both ends, and the height of the guardrails is the same as the height of the telescopic machine frame; the guardrails include protective plates and handrails, the handrails are vertically fixed to the two sides of the platform plate by welding, and the protective plates are fixedly installed on the inside of the handrails.

[0015] By adopting the above technical solutions, the guardrail can prevent the operator from tilting to the sides of the platform, thus preventing accidental falls. The protective plate can further cover the gaps at the edge of the platform, preventing small express parcels from sliding off the side. The handrail is the same height as the telescopic machine frame, making it easy for the operator to support and maintain balance, thus improving operational safety and convenience.

[0016] Preferably, the fixing bracket includes a vertical connecting rod and a horizontal connecting rod. The top and bottom of the vertical connecting rod are respectively connected to the mounting plate through the horizontal connecting rod, and an oblique connecting rod is also provided between the vertical connecting rod and the mounting plate.

[0017] By adopting the above technical solution, the vertical connecting rod, the horizontal connecting rod and the mounting plate form a frame-type fixed support, which has strong structural stability. The setting of the diagonal connecting rod makes the fixed support form a triangular reinforced structure. The triangle has the characteristic of being non-deformable, which can significantly improve the bending and torsional resistance of the fixed support, prevent the fixed support from deforming when the platform plate is loaded, and ensure the stability of the overall structure.

[0018] Preferably, the horizontal locking component includes a hook located on the side of the handrail near the fixed bracket; when the platform plate is in a horizontal working state, the hook is hooked onto the vertical connecting rod of the fixed bracket.

[0019] By adopting the above technical solution, the hook and the vertical connecting rod can be hooked together to firmly limit the platform plate to a horizontal position, preventing the platform plate from shaking, sinking or accidentally overturning due to the weight it bears; the hook is set on the handrail, which makes it easy for the operator to quickly align the hook when unfolding the platform plate, making the operation convenient and efficient.

[0020] Preferably, the vertical locking structure includes a pin and a slot. The pin is located on one side of the fixed bracket, and the slot is located at the bottom of the end of the protective plate away from the hook. The slot is a groove that matches the outer contour of the pin. When the platform plate is in a vertically retracted state, the pin is inserted into the slot.

[0021] By adopting the above technical solution, the matching and locking of the pin and the slot can firmly fix the vertically stored platform plate to the fixed baffle, effectively preventing the platform plate from accidentally unfolding or shaking during the movement and adjustment of the telescopic machine; the grooved slot is adapted to the outer contour of the pin to ensure that there is no loosening after locking, thus improving the safety in the stored state.

[0022] Preferably, the platform plate is provided with hydraulic rods symmetrically at both ends, the piston rod end of the hydraulic rod is hinged to the platform plate, and the cylinder end of the hydraulic rod is hinged to the vertical connecting rod of the fixed bracket.

[0023] By adopting the above technical solutions, the hydraulic rod can provide smooth assistance when the platform plate is flipped, reducing the operator's operating effort and preventing hand injuries caused by the platform plate falling rapidly due to its own weight; at the same time, hydraulic damping can achieve motion buffering, making the platform plate unfolding or retracting process smooth and without impact, extending the service life of components, and the hydraulic rod can also provide auxiliary support in the horizontal state, enhancing the stability of the platform.

[0024] Preferably, the platform plate has mounting seats at both ends of its bottom, and support rods are welded onto the mounting seats; when the platform plate is in a horizontally unfolded state, the lower end of the support rod abuts the ground.

[0025] By adopting the above technical solution, the contact between the support rod and the ground further distributes the weight borne by the platform plate, reduces the stress on the hook, and avoids bending and deformation of the platform plate after long-term use; the mounting base is welded to fix the support rod to ensure a stable connection, and the support rod does not occupy extra space when it is flipped and stored with the platform plate, and does not interfere with the operation of the telescopic machine.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By combining fixed baffles and platform plates for protection, the gap at the front of the telescopic machine is completely isolated. With anti-slip design, guardrails and double locking structure, the operator's safety is guaranteed from multiple dimensions, effectively eliminating the risk of pinching, slipping and other risks. 2. The platform can be folded and stored. When in a vertical position, it fits snugly against the fixed baffle, without affecting the telescopic range and movement path of the telescopic machine. This adapts to the busy operating rhythm of express distribution centers and ensures that loading and unloading efficiency is not affected. 3. The one-piece molded fixed bracket and fixed baffle make the platform have strong overall load-bearing capacity and good anti-deformation effect, which can adapt to the needs of long-term and frequent operation.

[0029] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail.

[0030] This application discloses an anti-pinch folding tipping bucket safety operation platform for telescopic conveyors in express delivery distribution centers.

[0031] Reference Figure 1 A folding tipping bucket safety operating platform for a telescopic conveyor in an express delivery distribution center, comprising a fixed bracket 2, a fixed baffle 3, a platform plate 4, a horizontal locking component, and a vertical locking structure. The fixed bracket 2 is located at the end of the telescopic conveyor frame 1. The fixed baffle 3 is fixedly installed on the fixed bracket 2. The platform plate 4 is hinged to the bottom of the fixed baffle 3. The platform plate 4 can rotate relative to the fixed baffle 3 around the hinge axis to achieve switching between working and storage states. The fixed baffle 3 is located on the side of the platform plate 4 closer to the telescopic conveyor frame 1. The horizontal locking component and the vertical locking structure are both set between the platform plate 4 and the fixed baffle 3. The horizontal locking component is used for stable locking when the platform plate 4 is horizontally unfolded, and the vertical locking structure is used for anti-loosening locking when the platform plate 4 is vertically folded.

[0032] When the platform plate 4 rotates to the horizontal working state, the horizontal locking component keeps the platform plate 4 horizontal. At this time, the fixed baffle 3 and the platform plate 4 form a safe operating platform, effectively isolating the operator from the gap at the end of the telescopic machine frame 1. The operator can stand safely on the platform plate 4 and place the goods steadily at the front end of the telescopic machine for transportation operations. When the platform plate 4 rotates to the vertical state, the side of the platform plate 4 that supports the operator is in close contact with the fixed baffle 3. The vertical locking structure prevents the platform plate 4 from being accidentally unfolded or moved, thereby avoiding the platform plate 4 from affecting the movement of the telescopic machine in the express distribution center and the passage of goods.

[0033] Reference Figure 1 and Figure 2Mounting plates 21 are fixedly connected to both sides of the fixed bracket 2. The mounting plates 21 are fixedly connected to the telescopic frame 1 by bolts. The fixed baffle 3 is set between the two mounting plates 22. The fixed bracket 2, the fixed baffle 3 and the mounting plates 21 are integrally formed.

[0034] Platform plate 4 is hinged to the bottom of fixed baffle 3 by heavy-duty hinge. Platform plate 4 can rotate around the heavy-duty hinge axis. With the help of horizontal locking parts and vertical locking structure, it can switch between horizontal working state and vertical storage state.

[0035] In this embodiment, the platform plate 4 is made of steel plate with a diamond-shaped anti-slip pattern. The steel plate is 1cm thick and has dimensions of 1200cm x 400cm. This type of steel plate not only has sufficient strength and rigidity to support the weight of heavy goods and operators, but its diamond-shaped anti-slip pattern provides additional friction, effectively preventing slippage accidents.

[0036] The side of the platform 4 used to support the operator is covered with an anti-slip mat 41, which increases the operator's comfort when standing on the platform 4 and provides additional anti-slip protection.

[0037] The platform plate 4 is equipped with guardrails 5 at both ends. The height of the guardrails 5 is consistent with the height of the telescopic frame 1, further ensuring the safety of the operator. The guardrails 5 include protective plates 52 and handrails 51. The handrails 51 are vertically fixed to the two sides of the platform plate 4 by welding, and the protective plates 52 are fixedly installed on the inside of the handrails 51.

[0038] Furthermore, the fixed bracket 2 includes a vertical connecting rod 22 and a horizontal connecting rod 23. The top and bottom of the vertical connecting rod 22 are connected to the mounting plate 21 via the horizontal connecting rod 23, and the horizontal connecting rod 23, the vertical connecting rod 22, and the mounting plate 21 are integrally formed. In addition, a diagonal connecting rod 24 is provided between the vertical connecting rod 22 and the mounting plate 21, forming a triangular reinforcing structure, which improves the bending and torsional resistance of the fixed bracket 2.

[0039] The horizontal locking mechanism includes two hooks 6, located on the side of the handrail 51 closest to the fixed bracket 2, with two hooks 6 on each side of the handrail 51. When the platform plate 4 is in a horizontal working state, the hooks 6 are accurately hooked onto the vertical connecting rod 22. Through the coordinated action of the hooks 6 and the vertical connecting rod 22, the platform plate 4 is firmly limited to a horizontal position, effectively preventing the platform plate 4 from swaying, sinking, or accidentally overturning under load.

[0040] Reference Figure 3When the platform plate 4 is not in use, the operator can apply force to the handrail 51 to flip the platform plate 4 upwards into a vertical storage state. During the flipping process, the fixed baffle 3 and the fixed bracket 2 remain fixed, and the platform plate 4 rotates around the axis of the heavy-duty hinge until the side of the platform plate 4 used to support the operator is in close contact with the fixed baffle 3. The vertical locking structure keeps the platform plate 4 in a vertical storage state.

[0041] Reference Figure 4 The vertical locking structure includes a pin 7 and a slot 8. The pin 7 is located on one side of the fixed bracket 2, and the slot 8 is located at the bottom of the protective plate 52 of the guardrail 5, away from the hook 6. The slot 8 is a groove that matches the outer edge of the pin 7. When the platform plate 4 is in the vertical storage state, the position of the slot 8 corresponds to the position of the pin 7. The pin 7 is inserted into the slot 8 axially. The pin 7 and the slot 8 cooperate to achieve mechanical locking, so that the platform plate 4 is firmly locked in the vertical storage position close to the fixed baffle 3, and cannot fall accidentally during transportation or movement.

[0042] Reference Figure 2 Hydraulic rods 9 are symmetrically provided at both ends of the platform plate 4. The piston rod end 91 of the hydraulic rod 9 is hinged to the platform plate 4, and the cylinder end 92 of the hydraulic rod 9 is hinged to the vertical connecting rod 23 of the fixed bracket 2. The hydraulic rod 9 uses the piston to provide tilting assistance, reduce the operating force, and at the same time realizes motion buffering through hydraulic damping to prevent the platform plate 4 from falling uncontrollably due to gravity when it is unfolded or retracted, ensuring smooth and safe operation, and enhancing the overall stability in the horizontal state.

[0043] In addition, mounting bases 42 are provided at both ends of the bottom of the platform plate 4, and the support rods 43 are fixed to the mounting bases 42 by welding. When the platform plate 4 is in the horizontal unfolded state, the lower end of the support rods 43 abuts against the ground, providing additional support for the platform plate 4 and enhancing the load-bearing stability; when the platform plate 4 is flipped up and retracted, the support rods 43 rotate with the platform plate 4, without interfering with the operation of the telescopic machine of the express distribution center or occupying extra space.

[0044] The implementation principle of this application embodiment is as follows: By setting a foldable platform plate 4, the front working area of ​​the telescopic conveyor in the express delivery distribution center is protected and conveniently stored. In use, the operator unfolds the platform plate 4 downwards to a horizontal position. The platform plate 4 and the fixed baffle 3 together seal the gap between the conveyor belt and the ground. Simultaneously, the hook 6 locks the platform plate 4, and the support rod 43 contacts the ground to enhance stability. Combined with the anti-slip surface and guardrail 5, this ensures operational safety. When not in use, the platform plate 4 is flipped upwards to fit tightly against the fixed baffle 3. A reliable lock is achieved through the engagement of the pin 7 and the slot 8. The overall structure is compact and does not affect equipment movement or passage. This design balances safety, stability, and ease of operation, effectively preventing the risk of pinching injuries and improving operational efficiency and space utilization.

[0045] 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.
