Technical Field
[0001] The utility model relates to a large low-speed marine diesel engine frame climbing operation safety protection pedal device, the invention can be used for a variety of large low-speed marine diesel engine frame climbing operation safety protection, the use of more convenient, simple and safe. Background Art
[0002] At present, the height of the racks produced by our department is more than 3 meters, which belongs to high-altitude operations. At present, when the overall assembly of the rack is carried out on the construction site, the operators use ladders or climbing ladders; when the operators construct in this way, someone on the ground is required to be responsible for safety protection to avoid the dangers of sliding and tipping of the ladders and climbing ladders, which increases labor costs and reduces construction efficiency. In order to improve production efficiency and the safety of high-altitude operations, it is necessary to design a convenient and safe protective device based on the overall width, height, appearance and other factors of the racks actually constructed on site to ensure the safety of related operations while taking into account the function of improving construction efficiency.

[0003] In view of the deficiencies in the prior art, the present invention provides a large low-speed marine diesel engine frame climbing operation safety protection pedal device which has a simple structure, is easy to operate and has high safety, and meets the requirements that one tool can be used for high-altitude operations of multiple large low-speed marine diesel engine frames at the same time.
[0004] The technical solution of the present invention is: a large low-speed marine diesel engine frame pedal device (referred to as pedal device), the two ends of the pedal are respectively placed on two load-bearing brackets, and the fixing pins pass through the pin holes at the end of the pedal and the pin holes on the load-bearing brackets respectively; each load-bearing bracket is composed of a crossbeam at the upper end, a bottom beam at the lower end, support ribs arranged longitudinally and connected between the crossbeam and the bottom beam, and hooks for hanging on the handles of the frame and fixed at the two longitudinal ends. When in use, the hooks of the two load-bearing brackets are used to install and fix the load-bearing brackets to the handles of the frame, and the pedals are laid flat on the load-bearing brackets and fixed with fixing pins. Thereby ensuring the safety of construction work on the upper part of the frame. After the device is applied, the production efficiency is improved, the safety of climbing work is ensured, and the danger of construction workers falling from heights is avoided.
[0005] The specific large low-speed marine diesel engine rack pedal device includes 1 pedal, 2 load-bearing brackets, and 4 fixing pins. Each load-bearing bracket is composed of 1 crossbeam, 1 bottom beam, 5 support ribs, and 4 hooks. When in use, the load-bearing brackets are installed and fixed to the handles of the rack using the hooks of the two load-bearing brackets, and the pedals are laid flat on the load-bearing brackets and fixed with fixing pins, thereby ensuring the safety of the upper construction work of the rack. This tooling solves the following problems:
[0006] 1. The insecurity of the rack climbing operation. It avoids the danger of falling from heights and reduces the difficulty of assembly and welding.
[0007] 2. Replace ladders or ladder racks and other equipment to simplify construction steps, improve production efficiency and reduce construction costs. BRIEF DESCRIPTION OF THE DRAWINGS
