Detailed Description

In order that the present invention may be more readily and clearly understood, a more particular description of the invention briefly described above will be rendered by reference to specific embodiments that are illustrated in the appended drawings.

The embodiment provides a portable and movable jig frame ladder, which comprises a standing platform 1 parallel to a horizontal plane, wherein four supporting columns 2 perpendicular to the standing platform 1 are fixedly installed on the lower end surface of the standing platform 1, and the four supporting columns 2 are respectively positioned at four corners of the standing platform 1. The right side of the standing platform 1 is provided with a ladder frame 3, the upper end of the ladder frame 3 is connected with the standing platform 1, and the lower end of the ladder frame 3 and the lower end of the supporting upright post 2 are positioned in the same horizontal plane. Constructors can climb up the standing platform 1 through the ladder frame 3 and then go up the jig frame on the standing platform 1.

Wherein, there are universal wheels 4 at the equal fixed mounting of the lower extreme of support column 2 and the lower extreme of ladder frame 3, make this bed-jig ladder portable through universal wheels 4, make constructor can follow the bed-jig in the suitable position.

Preferably, the universal wheel 4 includes a wheel frame 13 and a roller 14 rotatably installed in the wheel frame 13, a plurality of positioning slots 15 are vertically formed on an end surface of the roller 14, the positioning slots 15 penetrate through the end surface of the roller 14, and the plurality of positioning slots 15 are circumferentially and uniformly distributed with a rotation axis of the roller 14 as a center. The wheel frame 13 is correspondingly provided with a threaded hole 16, and a positioning screw rod is arranged in the threaded hole 16 in a penetrating way. The threaded hole 16 can be aligned with any one of the positioning slots 15, and when the threaded hole 16 can be aligned with any one of the positioning slots 15, the positioning screw can extend into the positioning slot 15, so that the roller 14 cannot rotate, and the jig frame ladder is fixed at a preset position.

In addition, the supporting upright post 2 comprises a supporting column 5 fixedly installed at the lower end of the standing platform 1 and a sleeve 6 coaxially sleeved outside the supporting column 5. The sleeves 6 can slide up and down on the support columns 5 to adjust the length of the support columns 2 and thus the height of the standing platform 1.

In this embodiment, a plurality of positioning holes 7 are formed in the supporting column 5, the positioning holes 7 penetrate through the supporting column 5 along the horizontal direction, and the positioning holes 7 are sequentially and equidistantly distributed along the length direction of the supporting column 5. The side surface of the sleeve 6 is correspondingly provided with a through hole 8, and the through hole 8 penetrates through the sleeve 6 along the horizontal direction. When the sleeve 6 slides up and down outside the supporting column 5, the through hole 8 can be aligned with any positioning hole 7, and at the moment, the positioning rod 9 is arranged in the through hole 8 and the aligned positioning hole 7 in a penetrating mode, so that the sleeve 6 cannot slide up and down, and the length of the supporting upright column 2 is fixed.

In another embodiment, an external thread 10 is arranged on the outer side surface of the support column 5, an internal thread matched with the external thread 10 is arranged on the inner side surface of the sleeve 6, and the sleeve 6 and the support column 5 are in threaded connection through the matching of the internal thread and the external thread 10. When the height of the supporting upright post 2 needs to be adjusted, only the sleeve 6 needs to be rotated.

In order to ensure that the height of the supporting upright posts 2 is adjusted, the lower ends of the ladder frames 3 can still be positioned in the same horizontal plane with the lower ends of the supporting upright posts 2, and the upper ends of the ladder frames 3 are hinged with the standing platform 1. When the length of the supporting upright post 2 is increased, the included angle between the ladder rack 3 and the horizontal plane can be increased; when the length of the supporting upright post 2 is reduced, the included angle between the ladder rack 3 and the horizontal plane can be reduced.

Further, a handrail 11 is fixedly attached to the front side of the ladder frame 3, and a platform fence 12 is fixedly attached to the front side of the standing platform 1. The safety of the constructor when standing on the platform 1 is further improved through the hand rails 11 and the platform guardrails 12, and the constructor can be provided with a jig frame on the rear side of the standing platform 1, so that the jig frame on the constructor cannot be influenced.

It should be noted that the plane where the hand rail 11 is located and the plane where the platform guardrail 12 is located are not in the same vertical plane, so as to avoid that the upper end of the hand rail 11 and the platform guardrail 12 are mutually abutted to influence the adjustment of the inclination angle of the ladder frame 3 when the inclination angle of the ladder frame 3 is adjusted.

In addition to the above embodiments, the present invention may have other embodiments; all the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope claimed by the present invention.
