Detailed Description

The present invention will be described in further detail with reference to specific examples.

Example (b):

as shown in fig. 1 to 4, the utility model discloses a foldable ladder for monorail crane driver's cabin, including rotating the pendulum rod 2 of connection in room door 11 bottom, the fixed pedal 21 that extends from free end one side of pendulum rod 2, locate 2 rotation ends of pendulum rod support dog 22 and two folding pedals 3 that are located fixed pedal 21 homonymies, when pendulum rod 2 is in the horizontality, fixed pedal 21 is located driver's seat 12 one side, support dog 22 and be used for restricting the pendulum rod 2 of vertical state toward the anterior swing of driver's cabin 1, folding pedal 3 rotates to be connected on pendulum rod 2 and can be fixed under two positions of parallel and level in pendulum rod 2 and perpendicular to pendulum rod 2. When the swing rod 2 is folded, the folding pedals 3 can be turned and flattened, and the fixed pedals 21 are positioned on the side of the driver seat 12, so that the movement of personnel is not influenced; when the swing rod 2 is pulled down, the folding pedals 3 can be turned to the position vertical to the swing rod 2, the supporting stop blocks 22 can abut against the bottom of the cab 2, and therefore a person can stably step on the folding pedals 3 or the fixed pedals 21. The ladder can be put down when personnel get on or off the cab of the monorail crane, and can be stored on the side of the cab at other times without occupying too much space. The length of the swing rod 2 can not touch the roadway ground, the number and the distance of the folding pedals 3 are suitable for adults to climb, and the limitation can not be made.

As shown in fig. 2, the end of the fixed pedal 21 is tilted toward the rotating shaft 4 of the swing link 2. This provides the rider with less risk of slipping when stepping on the fixed foot peg 21.

As shown in fig. 2, the folding foot support 3 includes L-shaped swinging blocks 31 coaxially and rotatably connected to both sides of the swinging rod 2 and a step pipe 32 connected between the two L-shaped swinging blocks 31. The L-shaped swing block 31 can make the step pipe 32 stay at two positions parallel to the swing link 2 and perpendicular to the swing link 2. When the step tube 32 is in the parallel position of the swing link 2, one surface thereof contacts the swing link 2. When the step tube 32 is in the vertical position of the swing link 2, one end thereof contacts the swing link 2. Thus, the step pipe 32 can be maintained in a horizontal state when a person steps on the step pipe 32.

As shown in fig. 2, the free end of the stepped tube 32 is provided with a stopper 33 for preventing slipping out. The stopper 33 can block the inner side of the sole of a person to prevent the person from slipping. The stepped tube 32 may be provided with other anti-slip structures to improve safety.

As shown in fig. 2 and 4, the swing link 2 is connected to a fixing block 13 at the bottom of the chamber door 11 through a rotating shaft 4, a spring retainer 6 is fixed at the outer end of the rotating shaft 4 by a screw 5, and a spring 7 is clamped between the spring retainer 6 and the fixing block 13. The spring 7 can apply an elastic force for blocking the swing rod 2 from rotating to the fixed block 13, so that the ladder is prevented from easily shaking after being stressed.

What has been described above is merely some embodiments of the present invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
