[0037] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The embodiments described in this application are only part of the embodiments of the utility model, not all of them. Based on the spirit of the utility model, other embodiments obtained by ordinary technicians in this field without creative work are all within the scope of protection of the utility model.

[0038] The left and right, up and down, front and back, inside and outside and other directions mentioned below are all based on the personnel facing the steel ladder of the prefabricated cabin of the power equipment. For example, the protective cage of the utility model is located on the upper part of the ladder and on the front side of the ladder.

[0039] like Figure 1 , 2 As shown, the utility model is a steel ladder for a prefabricated cabin of electric power equipment, the ladder comprising: a straight ladder 1 and a guard cage 2; the straight ladder 1 is arranged at the opening of the guard cage 2, and the guard cage 2 is located at the upper position of the straight ladder 1, the two are bolted and fixed, and the straight ladder 1 is detachably fixed on the outer surface of the prefabricated cabin of the electric power equipment.

[0040] Among them, the straight ladder 1 includes: a ladder frame 15, a foot pedal 6, a protective plate 5, a grounding nail 11 / 12, a hinge 10 and a padlock 9, the foot pedal 6, the protective plate 5, the grounding nail 11 / 12 and the padlock 9 are all fixedly arranged on the ladder frame 15, and the hinge 10 is movably arranged on the ladder frame 15; the protective cage 2 is an open circular structure, including a horizontal cage hoop 13 and a vertical rod 14, and the horizontal cage hoop 13 and the vertical rod 14 are fixedly connected.

[0041] like Figure 1 , 3 As shown, the ladder frame 15 includes: a ladder longitudinal beam 3, a ladder cross beam 4, a first leg 16, a second leg 17, a mounting beam 7, and a padlock lug 18; the ladder longitudinal beam 3, the ladder cross beam 4, the first leg 16 and the second leg 17 are all made of rectangular steel pipes with uniform labels, and the length of the first leg 16 is greater than that of the second leg 17; the mounting beam is a sheet metal structure; and the padlock lug is a steel welded plate.

[0042] like Figure 1 As shown, the ladder longitudinal beams 3 are arranged on the left and right, and the ladder cross beams 4 are arranged at equal intervals between the ladder longitudinal beams 3, and the two are fixed by full welding; the first leg 16 is a rectangular steel pipe with beveled ends fully welded between the ladder frame 15 and the ladder longitudinal beams 3; each second leg 17 is composed of two rectangular steel pipes of different lengths but equal numbers, which are fully welded on the ladder longitudinal beam 3, the first steel pipe of the second leg 17 is perpendicular to the ladder longitudinal beam, and the second steel pipe of the second leg 17 is at an acute angle to the ladder longitudinal beam, and a 45° angle is preferably selected in this embodiment, and the length of the second steel pipe of the second leg 17 is greater than the first steel pipe of the second leg 17; the mounting beam 7 is a "J"-shaped sheet metal bending part, the "J"-shaped protruding upper surface of which is welded and fixed to the end face of the second leg 17 of the ladder frame, and the "J"-shaped concave lower surface is fixed to the reserved mounting part of the prefabricated cabin of the power equipment by bolts, so as to facilitate the disassembly and assembly of the steel ladder and reduce the workload of on-site welding.

[0043] like Figure 4 As shown, the ladder longitudinal beam 3 is formed by integrated bending, and no additional handrails, railings, etc. are required, which reduces the processing steps and reduces the production cost. The ladder longitudinal beams on the left and right sides of the ladder frame have the same structure. The difference is that the left ladder longitudinal beam has a hinge fixing hole, and the right ladder longitudinal beam is equipped with a padlock lock ear 18. The hinge fixing holes and padlock lock ears on the left and right sides are interchangeable and also fall within the protection scope of the present utility model.

[0044] like Figure 2 , 5As shown, the foot pedal 6 is a steel grating plate welded to the middle and upper part of the ladder frame. In a preferred but non-restrictive embodiment of the utility model, the steel grating plate is 1050 mm away from the upper end of the ladder frame. The distance between the steel grating plate and the upper end of the ladder frame can be adjusted according to the actual equipment size, which is convenient for people to get on, and at the same time, water will not accumulate, ice will not form, etc., thereby ensuring the safety of people going up and down.

[0045] like Figure 1 , 4 As shown, the protective plate 5 is made of 5mm thick steel material. Other thicknesses or other materials that can achieve the protective effect are also within the protection scope of the utility model. One side is connected to the ladder frame through a hinge plate to achieve openability, and the other side is provided with a padlock ear clearance hole to ensure that the protective plate can be padlocked when closed. Prevent outsiders from climbing privately and ensure the safety of personnel and equipment. It should be noted that the padlock ear 18 is a steel welded plate not less than 5mm thick, and the bottom of the welded plate is fully welded to the ladder longitudinal beam 3.

[0046] like Figure 1 , 2 As shown, the cage 2 is an open circular structure, including horizontal cage hoops 13 and vertical poles 14. The number of horizontal cage hoops and vertical poles can be increased or decreased according to actual needs. The horizontal cage hoops are welded and fixed to the vertical poles, and the cage and the vertical ladder are fixed with M10 bolts. The horizontal cage hoops and vertical poles are respectively composed of the same components, wherein the spacing between adjacent horizontal cage hoops is the same, which is 900mm, and the angles between adjacent vertical poles and the center of the cage are the same, which is 45°. Other adjacent horizontal cage hoop spacings and adjacent vertical poles and the angles between the center of the cage also fall within the protection scope of the utility model. The connection between the 13 horizontal cage hoops and the 1 vertical ladder is a straight plane with a waist-shaped hole on the surface, which is fixed to the reserved circular hole of the ladder longitudinal beam of the vertical ladder by M10 bolts.

[0047] like Figure 2 As shown in the figure, there is a 60mm height difference between the cage and the ladder in the connection height. The main reason for the height difference is that the ladder longitudinal beam is an integrated bending structure with a bending fillet. Therefore, the height difference between the cage and the ladder will change with different bending fillet angles. Figure 2 As shown in the partial enlarged view, both the guard cage 2 and the ladder 1 are equipped with grounding screws, the specification of the grounding screws is M6×16, and the material is stainless steel.

[0048] like Figure 6 The figure shows the installation effect of the steel ladder. The steel ladder is bolted to the cabin to facilitate on-site construction operations.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or replaced by equivalents, and any modifications or equivalent replacements that do not depart from the spirit and scope of the utility model should be included in the scope of protection of the claims of the utility model.
