Embodiment 1

[0029] like Figure 1 to Figure 5 As shown, the present embodiment provides a special ladder for a vehicle frame, including a ladder frame, a hanging arm 1, a handrail 2, legs, and a step 4. The upper end of the ladder frame is fixed with a hanging arm 1 and a handrail 2, and the hanging arm 1 and the The handrails 2 are respectively located on both sides of the ladder frame. Outriggers are provided in the middle of the ladder frame. The outriggers are on the same side as the hanging arm 1 in a triangular structure. Steps 4 are fixed on the ladder frame.

[0030] The ladder frame includes two ladder beams 5 arranged in parallel, a plurality of steps 4 are fixed vertically at equal intervals between the two ladder beams 5 , and a hanging arm 1 and a handrail 2 are respectively fixedly connected to the upper end of each ladder beam.

[0031] Described supporting leg is provided with two groups, and each group of supporting leg all comprises two supporting leg rods, is respective...

Embodiment 2

[0035] like Image 6 As shown, it is basically the same as Embodiment 1, the difference is that: the first outrigger bar 31 and the second outrigger bar 32 are respectively hinged with the ladder beam 5, and can rotate vertically relative to the ladder beam 5, and the The first leg rod 31 is provided with a plurality of first pin shaft holes 311 along its length direction. One end of 5 is provided with a second pin hole, and can be fixedly connected with the first leg rod 31 through the second pin hole.

[0036] Before use, the angle of the legs relative to the ladder beam 5 can be adjusted by vertically rotating the first leg rod 31 and the second leg rod 32 according to the angle of the vehicle frame longitudinal beam 6. After the adjustment, the second leg rod The second pin hole on the leg bar 32 corresponds to one of the plurality of first pin holes 311 on the first leg bar 31, and the pin assembly 7 is used to fix the two to form a stable tripod structure. To meet the ...

Embodiment 3

[0038] like Figure 7 As shown, it is basically the same as Embodiment 1, the difference is that: the first outrigger bar 31 and the second outrigger bar 32 are respectively hinged with the ladder beam 5, and can rotate vertically relative to the ladder beam 5, and the The first outrigger rod 31 is provided with a through long hole 312 along its length direction, and the pin shaft assembly 7 is slidably connected in the through long hole 312. The second outrigger rod 32 is provided with a pin hole, and passes through the pin hole. It is fixedly connected with the pin shaft assembly 7.

[0039] A spring 8 is arranged in the through long hole 312, one end of the spring 8 is fixedly connected to the inner wall of the through long hole 312, and the other end is fixedly connected to the pin assembly 7, and a preload is applied to the spring 8 so that the spring 8 is always in a compressed state.

[0040] Before use, rotate the first outrigger rod 31 to unfold the first outrigger r...

Abstract

The invention discloses a ladder special for a vehicle frame. The ladder comprises a ladder rack, hanging arms, handrails, support legs and steppers. The hanging arms and the handrails are fixedly arranged at the upper end of the ladder rack, the hanging arms and the handrails are correspondingly located on the two sides of the ladder rack, the support legs are arranged in the middle of the ladderrack, the support legs and the hanging arms are on the same side to be presented of a tripod structure, and the ladder rack is fixedly provided with steppers. In use, the hanging arms of the ladder special for the vehicle frame are hung to the upper parts of a left longitudinal beam and a right longitudinal beam of the vehicle frame, the foot parts of the support legs tightly abut against the outer side arms of the left and right longitudinal beams, and personnel can hold the handrails to climb on the steppers when climbing up and down. According to the ladder special for the vehicle frame, the size is small, the weight is light, the ladder can be hung on the parts with small assembly space on the left and right longitudinal beams of the vehicle frame, moving is flexible, the ground surface is not occupied, a lot of space can be saved, thus the personnel climb up and down more flexible, more convenient, safer and more reliable, the structure is simple, manufacturing is easy, and materials are saved.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a special ladder for vehicle frames. Background technique [0002] In the prior art, when the vehicle frame is assembled, people mainly rely on step-type climbing ladders for people to go up and down. It is even more unusable in places with small assembly space. In order to solve this problem, a special ladder for vehicle frame is specially designed to solve this problem. Contents of the invention [0003] The invention provides a special ladder for a vehicle frame, which is small in size and light in weight, can be hung on the left and right longitudinal beams of the vehicle frame where the assembly space is small, and can move flexibly without occupying the ground, making it more flexible, convenient, safe and reliable for people to go up and down. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] A specia...
