Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, and in particular to a reciprocating vertical conveyor. Background Technology

[0002] Reciprocating vertical conveyors are primarily used for material transfer between floors in automated workshops. They essentially use a motor and chain structure to lift and lower the conveyor car, mainly designed for heavy materials, capable of handling loads of around 2 tons. They can replace elevators and are very suitable for retrofitting automated workshops. The main drawbacks of existing reciprocating vertical conveyors are: insufficient safety; inconvenient maintenance; and the reliance on forklifts for material loading and unloading. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the main objective of this invention is to provide a reciprocating vertical conveyor that is safe, easy to maintain, and convenient for feeding and discharging materials.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a reciprocating vertical conveyor, comprising a frame body, wherein a car and a drive mechanism capable of lifting and lowering the car are disposed within the frame body; the frame body includes a lower frame disposed on the first floor and an upper frame disposed on the second floor; the lower frame is provided with a lower inlet / outlet, and a high-speed rolling door and a safety light curtain are disposed at the lower inlet / outlet; the upper frame is provided with an upper inlet / outlet, and a high-speed rolling door and a safety light curtain are disposed at the upper inlet / outlet; a ladder is disposed on the outside of the frame body, the top of the ladder is connected to the top of the frame body, and a maintenance platform is disposed on the top of the frame body; a roller conveyor is disposed within the car.

[0005] Preferably, guardrails are provided on both sides of the roller conveyor.

[0006] Preferably, the four sides of the main frame are provided with protective netting.

[0007] Preferably, the main frame is fixedly mounted on a concrete foundation.

[0008] Compared with the prior art, the present invention has the following advantages: by integrating a roller conveyor to achieve automated loading and unloading, enhance safety protection (light curtain, protective net, guardrail, high-speed door), add a dedicated maintenance passage (ladder, platform), and optimize the overall structure (layered frame, concrete foundation fixation), it effectively solves the three core defects of traditional reciprocating vertical conveyors: poor safety, difficult maintenance, and reliance on forklifts. It provides a safer, more efficient, easier-to-maintain, and more automated vertical material conveying solution between floors. Attached Figure Description

[0011] The invention will now be further described with reference to the accompanying drawings.

[0012] like Figure 1 As shown, a reciprocating vertical conveyor includes a frame body 1, a car 2 and a drive mechanism 3 capable of lifting and lowering the car 2 are disposed in the frame body 1. The frame body 1 includes a lower frame 4 disposed on the first floor and an upper frame 5 disposed on the second floor. The lower frame 4 is provided with a lower entrance / exit 6, and a high-speed rolling door 7 and a safety light curtain 8 are provided at the lower entrance / exit 6. The upper frame 5 is provided with an upper entrance / exit, and a high-speed rolling door 7 and a safety light curtain 8 are provided at the upper entrance / exit. A ladder 9 is provided on the outside of the frame body 1, and the top of the ladder 9 is connected to the top of the frame body 1. A maintenance platform 10 is provided on the top of the frame body 1. A roller conveyor 11 is disposed in the car 2.

[0013] Preferably, guardrails 12 are provided on both sides of the roller conveyor 11.

[0014] Preferably, the four sides of the frame body 1 are provided with protective netting.

[0015] Preferably, the frame body 1 is fixedly mounted on the concrete foundation 13.

[0016] This solution presents a reciprocating vertical conveyor based on a frame structure, comprising a lower frame 4 and an upper frame 5 forming a vertical channel. A drive mechanism 3, such as a motor chain, drives a car 2 to reciprocate within the frame body 1, enabling vertical material transfer between floors. The core innovation lies in the built-in roller conveyor 11 within the car 2, along with a high-speed door and safety system. Its working principle is as follows: the drive mechanism 3 pulls the car 2 vertically within the frame, connecting the entrances and exits of different floors. Materials are automatically fed and discharged via the roller conveyor 11 within the car 2, replacing traditional forklift manual operation. High-speed roller shutters 7 installed at each floor's entrance and exit close during operation, forming a closed channel. Safety light curtains 8 monitor the entrance and exit areas in real time, stopping operation upon encountering an obstacle. An external ladder 9 leads directly to a maintenance platform 10 at the top of the frame, facilitating maintenance of the top components of the equipment. Systematic improvements have been made to address the pain points of existing technologies, resulting in significant advantages and greatly enhanced safety. Multiple layers of protection are incorporated, including safety light curtains 8 at each level's entrance and exit that effectively detect personnel or obstacles, triggering a shutdown. Protective netting on all four sides prevents external objects from entering the operating area or components from flying out. Guardrails 12 on both sides of the rollers in the car 2 prevent accidental material slippage. A high-speed rolling door 7 enables rapid opening and closing of the passageway, reducing the risk of external interference. Maintenance is convenient, with an external ladder 9 providing direct and safe access to the maintenance platform 10 at the top of the frame, completely solving the problem of difficult top-level maintenance in traditional equipment. Loading and unloading efficiency and automation are high. The built-in roller conveyor 11 in the car 2 allows materials to be automatically transported in and out, completely eliminating reliance on forklifts and significantly improving loading and unloading speed and automation, better meeting the needs of modern workshop logistics. The structure is robust and reliable, with the main frame 1 fixedly mounted on a concrete foundation 13, ensuring stable operation and making it particularly suitable for carrying heavy loads (approximately 2 tons).

[0017] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
