Description

Technical Field

[0001] This utility model relates to the technical field of fall protection devices, specifically a high-sided, mobile, retractable, multi-person fall protection device for loading onto vehicles. Background Technology

[0002] In logistics transportation and cargo loading and unloading operations, high-sided trucks are widely used for transporting various types of goods due to their large loading capacity and wide applicability. However, ensuring the safety of workers during the loading process of high-sided trucks has always been a critical issue that urgently needs to be addressed.

[0003] Typically, workers need to stand inside the cargo compartment of a high-sided truck to load and unload goods. As cargo is loaded, once full, the workers' working surface gradually rises above the level of the truck's guardrails. At this point, workers lose the effective protection of the guardrails and are at a higher working height, increasing the risk of falls. Furthermore, the cargo loaded on high-sided trucks is often of various shapes and uneven surfaces, making it extremely easy for workers to slip or trip over the cargo while walking and operating on it, further increasing the likelihood of falls.

[0004] In actual loading processes, the loading location is not fixed and changes frequently depending on the type and quantity of goods and loading requirements. High-sided trucks are relatively long, resulting in a correspondingly long area requiring fall protection. Traditional fall protection devices mostly only protect single individuals and cannot meet the needs of multiple people working simultaneously. Furthermore, these devices are usually fixed in one location and cannot be moved flexibly according to changes in loading location. They also cannot be extended or retracted in the width direction, causing significant inconvenience for movement and handling, and occupying a large amount of space in warehouses, affecting warehouse space utilization. Therefore, a mobile, retractable, multi-person fall protection device for high-sided truck loading is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a high-sided, mobile, retractable, multi-person fall prevention device for loading onto vehicles, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-sided, mobile, retractable, multi-person fall prevention device, comprising multiple front rails and the same number of rear rails. The bottom ends of both the front and rear rails are equipped with casters. A connecting rod is hinged to the lower part of the outer side wall of each front rail, and a connecting rod is hinged to the lower part of the outer side wall of each rear rail. The middle parts of connecting rod one and connecting rod two are hinged by rivets. A sliding rod is hinged to the top of the outer side wall of both connecting rod one and connecting rod two. An elongated hole is provided on the upper part of the outer side wall of both the front and rear rails. The sliding rod passes through the elongated hole and is slidably connected to it. A heightening rod is fixedly connected to the top of the rear rail. Hooks are fixedly connected to the top of the opposite side of the front and rear rails and to the top of the front surface of the heightening rod. A protective net is hung on the outer side of the hook. A locking rod is threadedly connected to the outer side wall of both the front and rear rails. One end of the locking rod extends into the elongated hole and is close to the bottom of the elongated hole.

[0007] As a further preferred embodiment of this technical solution: the protective net includes three hanging rods, the hanging rods are hung on the hooks, and a net body is fixed between the outer walls of the hanging rods.

[0008] As a further preferred embodiment of this technical solution: a knob is fixedly connected to the other end of the lever.

[0009] As a further preferred embodiment of this technical solution: crossbars are uniformly and fixedly connected between the outer walls of the front rail and between the outer walls of the rear rail.

[0011] As a further preferred embodiment of this technical solution: magnetic blocks are fixedly connected to the left side of the inner wall of the card holder and the left end of the baffle.

[0012] As a further preferred embodiment of this technical solution, a pull ring is fixedly connected to the right side wall of the barrier.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model's movable fall arrestor allows the front rail to be close to and fitted against the high-sided truck during operation, with the protective net covering one side of the truck, providing a large protection range and simultaneously protecting multiple people. Utilizing the mobility of the casters, it can be flexibly moved according to changes in loading position, improving the device's usability. By squeezing the front and rear rails, the sliding rod slides upward within the elongated hole, bringing the front and rear rails closer together. This allows for retraction in the width direction, facilitating movement and handling. During protective use, the front and rear rails are extended away from each other, and the locking lever is turned to secure the sliding rod at the bottom of the elongated hole, locking the distance between the front and rear rails and preventing accidental retraction that could compromise safety. When stored in a warehouse, retracting the front and rear rails saves considerable space, preventing any impact on warehouse space utilization and greatly facilitating the use of the fall arrestor.
