Description

Technical Field

[0001] The utility model relates to the technical field of operating machinery, in particular to a folding ladder platform. Background Art

[0002] Before tobacco is cut into shreds, it is necessary to manually monitor and remove impurities from the tobacco to prevent impurities from entering the shredder and causing damage to the equipment or affecting the quality of the tobacco. Manual monitoring and impurity removal means that the monitoring personnel monitor whether there is any impurity in the buffer cabinet of the feeder. When the monitoring personnel finds impurities in the material, the feeder needs to be stopped and the operator needs to be sent into the buffer cabinet to remove the impurities. After cleaning up the impurities, the operator needs to climb out of the buffer cabinet. In the prior art, before the operator enters the buffer cabinet, it is necessary to put the inclined ladder into the buffer cabinet in advance, and then step on the inclined ladder to enter the buffer cabinet. After completing the impurity removal work, step on the inclined ladder to climb out of the buffer cabinet, and finally move the inclined ladder out of the buffer cabinet. In order to prevent the inclined ladder from occupying a large space in the buffer cabinet and affecting material transportation, when removing impurities, the operator needs to frequently move the inclined ladder in and out of the buffer cabinet, but frequently moving the inclined ladder is time-consuming and laborious.

[0029] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] The embodiment of the utility model provides a folding ladder platform for assisting operators to enter and exit the buffer cabinet, such as Figure 1 As shown, the folding ladder comprises: a frame 1, a ladder assembly 4 and a stop block 6. The frame 1 comprises two parallel longitudinal beams 2, at least two transverse beams 3 are arranged between the two longitudinal beams 2, and the two ends of the transverse beam 3 are respectively fixedly connected to the two longitudinal beams 2. The longitudinal beams 2 extend in a first direction ( Figure 1 and Figure 2 X direction), the transverse beam 3 extends along the second direction ( Figure 1 and Figure 2 The first direction of the ladder assembly 4 is perpendicular to the first direction and is horizontal. The ladder assembly 4 is arranged between the two longitudinal beams 2. The ladder assembly 4 includes a pedal 5. The two ends of the pedal 5 are respectively hinged to the two longitudinal beams 2. The pedal 5 can rotate between a first position and a second position. The limit block 6 is arranged on the longitudinal beam 2. The limit block 6 is provided with a first limit surface 7. The first limit surface 7 is parallel to the horizontal plane. When the pedal 5 rotates to the first position, it is in an unfolded state. Figure 3 As shown, the pedal 5 is in contact with the first limiting surface 7; when the pedal 5 rotates to the second position, it is in the storage state, as shown in FIG. Figure 4 As shown, along the second direction, the projection of the pedal 5 is located within the projection range of the longitudinal beam 2 .

[0031] By adopting the above technical solution, a pedal 5 hinged to the longitudinal beam 2 is provided on the frame 1 of the folding platform, and the pedal 5 can be rotated between a first position and a second position, so that the pedal 5 can be unfolded and folded. When the operator needs to step on the pedal 5, the pedal 5 is rotated to the first position, and the folding platform is in the unfolded state. Figure 3As shown, the pedal 5 is unfolded to be parallel to the horizontal plane, which is convenient for the operator to step on. When the operator completes the operation, the pedal 5 is rotated to the second position, and the folding ladder is in the storage state. Figure 4 As shown, the pedal 5 is retracted into the frame, which can reduce the overall volume of the platform and prevent the platform from occupying a large space in the buffer cabinet. Therefore, the platform can be retained in the buffer cabinet when not in use, avoiding the waste of manpower and time caused by frequent movement of the platform.

[0032] Furthermore, if Figure 1 and Figure 2 As shown, the pedal 5 includes a first edge 9 and a second edge 10 which are parallel to each other, and the first edge 9 and the second edge 10 both extend along the second direction. Both ends of the first edge 9 are provided with a first hinge shaft 11 extending along the second direction, and each longitudinal beam 2 is provided with a connecting hole 12, and each first hinge shaft 11 is hinged to each connecting hole 12, so that the pedal 5 can rotate around the first hinge shaft 11 between the first position and the second position.

[0033] Furthermore, if Figure 1 and Figure 2 As shown, the ladder platform assembly 4 includes at least two pedals 5 and two connecting rods 13, each pedal 5 is arranged at intervals along the first direction, and a second hinge shaft 14 is provided at both ends of the second edge 10 on each pedal 5, one connecting rod 13 is respectively hinged to each second hinge shaft 14 located on the same side of the second edge 10, and the other connecting rod 13 is respectively hinged to each second hinge shaft 14 located on the other side of the second edge 10. Both connecting rods 13 are parallel to the longitudinal beam 2, and each pedal 5 is parallel to each other. When each pedal 5 rotates between the first position and the second position, it can rotate the same angle, which is convenient for rotating each pedal 5 to the unfolded state or the stored state at the same time.

[0034] Furthermore, a second limiting surface 8 is provided on the limiting block 6. When the pedal 5 rotates to the second position, the pedal 5 fits the second limiting surface 8 to limit the rotation limit position of the pedal 5 to the second position. At this time, along the second direction, the projection of the pedal 5 is located within the projection range of the longitudinal beam 2, so that the pedal 5 is received inside the frame 1 to prevent the pedal 5 from occupying the space in the buffer cabinet.

[0035] Furthermore, a limit lock 15 is provided on the longitudinal beam 2, and the limit lock 15 includes a lock tongue 16. The lock tongue 16 can be extended or retracted along the second direction. When the pedal 5 is rotated to the second position, the lock tongue 16 can be extended to the side of the pedal 5 away from the limit block 6 to limit the pedal 5 from rotating toward the first position, so as to facilitate limiting the pedal 5 in the storage state and prevent the pedal 5 from accidentally rotating to the expanded state and occupying the space in the buffer cabinet.

[0036] Furthermore, a downwardly bent portion 17 is provided at the top end of the longitudinal beam 2, and a slot 18 is formed between the bent portion 17 and the longitudinal beam 2. In this embodiment, the first direction is a vertical direction, and both side walls of the slot 18 extend in the vertical direction. The side panel of the buffer cabinet can be inserted into the slot 18 to limit the downward movement of the frame 1, so that when the operator steps on the pedal 5, the pedal 5 can be kept stable in the vertical direction.

[0037] Furthermore, the slot 18 is clearance-matched with the side plate of the buffer cabinet, so as to facilitate the folding ladder to be hung on the side plate of the buffer cabinet.

[0038] Furthermore, the distance between the two longitudinal beams 2 is 400-500 mm.

[0039] Furthermore, the length of the longitudinal beam 2 is 800-1000 mm.

[0040] Although the present invention has been illustrated and described with reference to certain preferred embodiments of the present invention, it should be understood by those skilled in the art that the above contents are further detailed descriptions of the present invention in combination with specific embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. Those skilled in the art may make various changes in form and details, including making several simple deductions or substitutions, without departing from the spirit and scope of the present invention.
