Abstract
The utility model discloses a rotary anti-collision ladder. The end face of a driving platform is provided with a permanent seat (2) for a rotary shaft, the periphery of the permanent seat (2) of the rotary shaft is provided with a plurality of positioning sleeves (3), and the positioning sleeves (3) are provided with springs (8), steel balls (9) and pressure regulating bolts (5), which are locked by nuts (6) ; and the inner end face on the upper part of a suspended ladder (1) is welded with a rotary shaft (7), the rotary shaft (7) passes through the permanent seat of the rotary shaft (2) and is locked by a fixed nut (4), and the steel balls (9) are pressed against the inner end face of the suspended ladder (1). The rotary anti-collision ladder is locked in position in natural state, and rotates when the impact reaches a certain degree, thereby realizing self protection, and reducing damages to the driving platform caused by the deformation of the suspended ladder.
Description
Technical field
The utility model belongs to the farm machinery technical field, refers more particularly to the crashproof ladder of a kind of rotation.
Background technology
The structure of operator's compartment hanging ladder is on the sidewall that is fixed on operator platform in the at present domestic harvest machinery industry.The hanging ladder of this fixed sturcture when running into obstacle in the harvest machinery practical work process, damages easily.
Summary of the invention
In order to overcome the existing in prior technology deficiency, the utility model has designed the crashproof ladder of a kind of rotation, and this crashproof ladder can satisfy the function of boarding normally, can adapt to different environment, can change state automatically when running into bump, guarantee that the structure of ladder is intact, reduce damage operator platform.
For achieving the above object, the utility model adopts following technical scheme:
The crashproof ladder of described rotation is that the end face at operator platform is provided with a rotating shaft permanent seat, is provided with some locating sleeves around the rotating shaft permanent seat, and equipped spring, steel ball and regulator bolts in the locating sleeve are by nut locking; Hanging ladder upper interior end face is welded a rotating shaft, and rotating shaft is equipped with tightly by captive nut after passing the rotating shaft permanent seat, and steel ball withstands on the hanging ladder inner end surface.
Because adopt aforesaid technical scheme, the utility model produces following good effect:
1, the crashproof ladder of rotation energy latched position under state of nature has only when impulsive force arrives and to a certain degree could rotate, and realizes self-protection.
2, the protection hanging ladder is not damaged, and reduces because of the damage of hanging ladder distortion to operator platform.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the upward view of Fig. 1.
Fig. 3 is the A-A section-drawing of Fig. 2.
Among the above-mentioned figure: the 1-hanging ladder; 2-rotating shaft permanent seat; The 3-locating sleeve; The 4-captive nut; The 5-regulator bolts; The 6-nut; The 7-rotating shaft; The 8-spring; The 9-steel ball.
The specific embodiment
In Fig. 1,2,3, the crashproof ladder of rotation of the present utility model is that the end face at operator platform is provided with a rotating shaft permanent seat (2), be provided with some locating sleeves (3) all around at rotating shaft permanent seat (2), equipped spring (8), steel ball (9) and regulator bolts (5) are locked by nut (6) in the locating sleeve (3); Hanging ladder (1) upper interior end face is welded a rotating shaft (7), and rotating shaft (7) is passed rotating shaft permanent seat (2) back and is equipped with tightly by captive nut (4), and steel ball (9) withstands on hanging ladder (1) inner end surface.
Regulator bolts (5) is screwed on the locating sleeve (3) in advance, spring (8) and steel ball (9) are also put into locating sleeve (3) again rotating shaft permanent seat (2) is passed in the rotating shaft (7) on the hanging ladder (1), be installed on the operator platform by two captive nuts (4), it is locked two captive nuts (4) to install the back, final adjustment look nut (6) makes spring push away steel ball (9) can just block hanging ladder (1) to the pressure of hanging ladder (1), and can bear certain impact.
Welding a S. A. (7) perpendicular to hanging ladder (1) upper interior end face, in the rotating shaft permanent seat (2) on S. A. (7) the insertion operator platform, hanging ladder (1) is installed on the operator platform, and, make hanging ladder (1) energy latched position under state of nature at the coaxial circumference of rotating shaft (7) equal portion locating sleeve (3) and the spring (8) of being joined, steel ball (9) and regulator bolts (5).Have only the impulsive force of working as to arrive to a certain degree, could rotate, realize self-protection.
Claims (1)
1, the crashproof ladder of a kind of rotation, it is characterized in that: the end face at operator platform is provided with a rotating shaft permanent seat (2), be provided with some locating sleeves (3) all around at rotating shaft permanent seat (2), equipped spring (8), steel ball (9) and regulator bolts (5) are locked by nut (6) in the locating sleeve (3); Hanging ladder (1) upper interior end face is welded a rotating shaft (7), and rotating shaft (7) is passed rotating shaft permanent seat (2) back and is equipped with tightly by captive nut (4), and steel ball (9) withstands on hanging ladder (1) inner end surface.
