Anti-falling ladder protection operation device and protection operation method for vehicle loading and unloading

Abstract

The invention belongs to an anti-falling ladder protection operation device for vehicle loading and unloading and a protection operation method. Comprising an anti-falling ladder base, the top of the anti-falling ladder base is provided with a lifting unit used for adjusting the height, the top of the lifting unit is provided with a protection unit, and the outer surface of the lifting unit is provided with a trailer tensioning part connected with a vehicle and a fixed supporting part matched with the trailer tensioning part and used for limiting; the protection unit comprises an L-shaped connecting rod, one end of the L-shaped connecting rod is connected with the top of the lifting unit, and the other end of the L-shaped connecting rod is provided with a hanging ring used for fixedly installing a falling protector or a safety belt. The lifting device has the advantages of being simple in structure, reasonable in design and capable of achieving vertical lifting and tight fixation with vehicles according to different heights of the vehicles and goods so as to facilitate installation of a falling protector and a safety belt.

Description

technical field [0001] The invention belongs to the technical field of safety protection for high-altitude operations, in particular to an anti-falling ladder protection device and a protection operation method for vehicle loading and unloading, which provide safety protection during vehicle loading and unloading operations. Background technique [0002] In the process of vehicle loading and unloading, it is usually necessary for loading and unloading personnel to work in the body of the vehicle trailer, especially during the process of loading and unloading goods, it is necessary to work on the edge of the body; The danger of reaching the ground; in order to overcome the above-mentioned defects, some enterprises have developed corresponding safety protection equipment, such as: the patent number is 201710189933.3, the patent name is: mobile safety protection equipment for loading and unloading personnel of trucks; the patent discloses an up and down telescopic anti-fall colu...

AI Technical Summary

Problems solved by technology

The above-mentioned structure has the following defects: 1. Since the model of the vehicle is not fixed, and the bottom of the truck is equipped with water tanks, fuel tanks, and bumpers, the installation range of the above-mentioned devices is limited, and its application range is further restricted; 2. The outside of the cargo is generally covered with rain-proof components such as canvas. The distance between the up and down telescopic anti-fall columns of the above-mentioned device and the vehicle body is uncontrollable. When loading and unloading cargo, it needs to be fixed twice, which increases the labor intensity.

3. The above-mentioned device is fixed by the chassis of the vehicle; after it is tightly fixed, if the operation of loading goods is carried out, the chassis will move downward with the increase of the weight of the goods and generate downward pressure on the above-mentioned device, which is huge. It is enough to affect the service life of related equipment such as hydraulic lifting poles. In severe cases, it will be damaged during use; when the cargo is unloaded, the chassis will move downward as the weight of the cargo decreases. The height of the lifting plate vertical rod is adjusted to ensure the safety of loading and unloading personnel. It has the problems of complicated operation, the need to adjust the equipment during operation, and potential safety hazards; similarly, the patent number 200990100201.1, the patent name is: a A detachably connected fall restraint device; it discloses a technical solution for fixing the fall restraint device using truck wheels, which also has the defects of Article 2 and Article 3 of the aforementioned patents; the further technical solutions of the above two patents are both It is to press the vehicle (chassis or tire) on the limit device to realize the fixation of the limit device. This fixing method is highly dependent on the type of vehicle and the condition of the cargo, especially when the vehicle moves by mistake. , there is a great safety risk; based on the above content, it can be seen that in the actual vehicle loading and unloading process, there are unfixed vehicle models that affect the use, low fixation between the anti-fall device and the vehicle, and potential safety hazards. The defect of cumbersome operation process of secondary fixation and multiple fastening
