Description

Technical Field

[0001] The utility model provides a climbing frame for maintenance of diesel locomotives, belonging to the technical field of climbing frames. Background Art

[0002] Climbing frames are tools used by workers to climb up and down. There are many kinds of such tools, such as ladders, stepladders, scaffolding, elevators, etc., which are widely used in various equipment maintenance work at a certain height. Diesel locomotives use internal combustion engines as the original power and drive the wheels through transmission devices. According to the type of fuel used by the internal combustion engine on the locomotive, most of the diesel locomotives used on my country's railways are equipped with diesel engines. At present, climbing frames are usually needed when repairing and maintaining the side walls and top walls of diesel locomotives.

[0003] The existing climbing frame can basically meet the normal use needs, but when in use, it can usually only be raised and lowered on one side of the diesel locomotive, so that the staff can stand on the climbing frame to repair and maintain the side wall of the diesel locomotive. However, due to the certain distance between the climbing frame and the side wall of the diesel locomotive, it is often inconvenient to climb safely and smoothly to the roof of the diesel locomotive through the climbing frame to perform maintenance work. Based on this, the utility model provides a climbing frame for diesel locomotive maintenance. Utility Model Content

[0006] Furthermore, universal wheels are symmetrically arranged on both sides of the bottom of the base, and brake pads are arranged on the universal wheels.

[0007] Furthermore, the guardrail includes vertical poles symmetrically arranged on the top of the extension plate, and handrails are arranged between the tops of the vertical poles.

[0008] Furthermore, the side walls around the lower end of the column are provided with a first reinforcing rib fixedly connected to the top of the base, and the side walls at the upper end of the column are provided with a second reinforcing rib fixedly connected to the bottom wall of the extension plate.

[0017] The utility model is further described below in conjunction with the accompanying drawings.

[0018] According to the attached Figure 1 As shown: the utility model provides a climbing frame for maintenance of diesel locomotives: it includes a base 1, a ladder 2 is arranged on the top of the base 1, the ladder 2 includes columns 7 symmetrically fixedly arranged on the top of the base 1, a plurality of support rods 8 are equidistantly arranged between the columns 7, and the side walls around the lower ends of the columns 7 are provided with reinforcing ribs 13 fixedly connected to the top of the base 1, which play a role in strengthening the fixation, universal wheels 9 are symmetrically arranged on both sides of the bottom of the base 1, and brake pads 10 are arranged on the universal wheels 9. The climbing frame can be conveniently moved to a suitable position as a whole through the universal wheels 9 and locked through the brake pads 10. The staff can climb up to a suitable height by stepping on the support rods 8, and then can stand on the support rods 8 to perform maintenance work on the side wall of the diesel locomotive.

[0019] According to the attached Figure 2 , 3As shown: an extension plate 3 is fixedly connected to the top of the ladder 2, and a reinforcing rib 14 is provided on the upper side wall of the column 7 and fixedly connected to the bottom wall of the extension plate 3 to strengthen the fixation. Guardrails 4 are symmetrically provided at both ends of the top of the extension plate 3. The guardrails 4 include uprights 11 symmetrically arranged on the top of the extension plate 3, and a handrail 12 is provided between the tops of the uprights 11 to play a protective role. An electric push rod 5 is symmetrically provided at one end of the bottom of the extension plate 3 away from the ladder 2, and a support plate 6 is provided between the telescopic rod ends of the electric push rod 5. An anti-skid pad 15 is provided at the bottom of the support plate 6. By starting the electric push rod 5, the support plate 6 and the anti-skid pad 15 are driven to move downward until the anti-skid pad 15 moves downward to fit closely with the roof of the diesel locomotive, so that it is convenient for the staff to climb to the roof of the diesel locomotive through the extension plate 3 to perform maintenance work.

[0020] According to the attached Figure 1 As shown: a battery 16 is provided on the top of the base 1, which is placed between the columns 7 and electrically connected to the electric push rod 5.
