Abstract
Description
Technical Field
[0001] This utility model relates to the field of safety auxiliary devices, specifically to an auxiliary safety frame. Background Technology
[0002] Trucks transporting bauxite must be covered with tarpaulins before leaving the factory. Bauxite is usually in powder or granular form, and dust is easily generated during transportation. Tarpaulins can effectively prevent dust from spreading, reduce air pollution, meet environmental protection requirements, and also provide rain and moisture protection. Bauxite may clump or undergo chemical reactions when it comes into contact with water, affecting its quality. Tarpaulins can prevent rainwater from soaking the goods and ensure the dryness and usability of the bauxite.
[0003] In existing technologies, for some ordinary trucks or vehicles without automatic tarpaulin systems, setting up the tarpaulin relies on manual operation. Workers climb onto the truck and unfold the tarpaulin from the front or rear, gradually covering the entire cargo box. However, due to the lack of any protective measures, and the fact that the cargo box is usually quite high, workers are prone to slipping and falling from the truck, resulting in injuries and frequent accidents. Therefore, there is an urgent need for a safety frame to assist workers in setting up tarpaulins, thereby reducing the occurrence of accidents. Utility Model Content
[0004] The present invention aims to provide an auxiliary safety frame, which is a safety auxiliary device to assist workers in setting up tarpaulins.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An auxiliary safety frame includes a gantry and a platform. The platform is at the same height as the cargo box of a freight car is at the same height as the ground. A support frame is fixedly installed on the platform. A taut steel cable is fixedly installed between the top of the gantry and the top of the support frame. A movable safety ring is looped around the steel cable. A safety rope extending to the platform is fixedly connected to the safety ring.
[0007] The working principle and beneficial effects of this utility model:
[0008] In this application, the loaded truck reverses towards the platform, moving the cargo box to the platform for connection. Workers climb onto the platform, securing safety ropes to their bodies (e.g., by tying the safety rope tightly around their waists), and then walk across the platform onto the cargo box to set up the tarpaulin. Throughout the process, the steel rope remains taut, and the safety rope is connected to the steel rope via a safety ring. The safety ring moves along the steel rope to facilitate the workers' movement on the cargo box. This not only makes it convenient for workers to set up the tarpaulin, but also ensures that even if a worker slips and falls from the cargo box, the steel rope, safety ring, and safety rope will pull the worker upwards, preventing them from falling directly to the ground and sustaining injuries, thus eliminating the risk of accidents.
[0009] In some embodiments, there are multiple platforms, which are fixedly connected to each other, and the platforms have different ground clearances. Because different types of freight trucks have different ground clearances for their cargo compartments, multiple platforms of different heights are provided to facilitate easy access for workers from the platforms to the cargo compartments.
[0010] In some embodiments, the platform is equipped with escalators. The escalators facilitate workers climbing onto the platform.
[0011] In some embodiments, the escalator is installed at the rear of the platform, with the front of the platform facing the gantry.
[0012] In some embodiments, a stone block is fixed between the gantry and the platform to limit the movement of the freight car's wheels. The distance between the stone block and the platform is equal to the distance between the rear wheels of the freight car and the side of the cargo box facing the platform. When the freight car reverses towards the platform, after the rear wheels of the freight car contact the stone block, the stone block prevents the freight car from continuing to reverse, at which point the cargo box is just connected to the platform.
[0013] In some embodiments, the safety rope is fixedly connected to a high-altitude work safety belt. A high-altitude work safety belt is a commonly used tool for working at heights. Before starting work, the worker first threads the high-altitude work safety belt through which the worker is pulled upwards by steel ropes, safety rings, safety ropes, and the high-altitude work safety belt.
[0014] Attached Figure Description Figure 1 This is a schematic diagram of the internal structure of an auxiliary safety frame according to this application;
[0015] Figure 2 This is a schematic diagram of the connection between the safety rope and the safety ring in Example 2. Detailed Implementation
[0016] The following detailed description illustrates the specific implementation method:
[0017] The reference numerals in the accompanying drawings include: gantry 1, truck 2, safety ring 3, safety rope 4, support frame 5, escalator 6, platform 7, cargo box 8, steel rope 9, and high-altitude work safety belt 10.
[0018] In the following statements, directional terms such as "left," "right," "up," and "down" are based on the directions shown in the diagram. In practice, if the corresponding structures are changed in the same direction based on the direction while maintaining their relative positions, it will not affect the implementation of the plan.
[0019] Example 1: An auxiliary safety frame, such as Figure 1As shown, the system includes a gantry frame 1 fixed to the ground by pouring concrete and a platform 7. The height of the platform 7 above the ground is equal to the height of the cargo box 8 of the freight truck 2 above the ground. An escalator 6 is installed on the side of the platform 7. A support frame 5 is fixedly installed on the top of the platform 7. A taut and horizontal steel cable 9 is fixed between the top of the gantry frame 1 and the top of the support frame 5. A movable safety ring 3 is sleeved on the steel cable 9. A safety rope 4 extending to the platform 7 is fixedly connected to the safety ring 3.
[0020] In this application, the loaded truck 2 passes through the gantry 1 and reverses towards the platform 7, moving the cargo box 8 to connect with the platform 7. The workers climb onto the platform 7, secure the safety rope 4 to their bodies (e.g., tie the safety rope 4 tightly around their waist), and walk across the platform 7 onto the cargo box 8 to set up the tarpaulin. Throughout the process, the steel rope 9 remains taut and horizontal, while the safety rope 4 is connected to the steel rope 9 via a safety ring 3. The safety ring 3 moves along the steel rope 9 to facilitate the workers' movement on the cargo box 8. This not only makes it convenient for the workers to set up the tarpaulin, but also ensures that even if the workers accidentally fall from the cargo box 8, the steel rope 9, safety ring 3, and safety rope 4 will pull the workers upwards, preventing them from falling directly to the ground and sustaining injuries, thus eliminating the risk of accidents.
[0021] Example 2: The difference from Example 1 is that, as Figure 2 As shown, the safety rope 4 is fixedly connected to the high-altitude work safety belt 10. The high-altitude work safety belt 10 is a commonly used component in this field; its working principle and structure are described in Baidu Encyclopedia. The high-altitude work safety belt 10 is also known as an all-around safety belt or a five-point safety belt. One end of the safety rope 4 is fixed to the high-altitude work safety belt 10. Before starting work, the worker puts on the high-altitude work safety belt 10, and the worker is pulled upwards by the steel rope 9, safety ring 3, safety rope 4, and high-altitude work safety belt 10.
