The number of the surrounding frames is at least three; the connecting ribs are at least four, the horizontal sections of at least two connecting ribs are arranged along the X direction, and the horizontal sections of at least two connecting ribs are arranged along the Y direction.

The length of the vertical section L1 to which the hook is attached is longer than the length of the vertical section L2 to which the back hook is attached.

And the contact positions of the connecting ribs and the surrounding frames are welded and fixed, and the contact positions of the horizontal sections of the connecting ribs are welded and fixed. All the contact positions are welded firmly to form the cage into a whole.

The contact positions between the horizontal sections of the connecting ribs are welded and fixed to form the bottom surface of the suspension cage body.

And wood plates are laid on the bottom surface of the lifting cage body.

The distance L3 between the bottom surface of the suspension cage body and the uppermost surrounding frame is at least 1.5 m; the average height of the person is considered, and the person can not turn out of the uppermost surrounding frame when standing at the bottom of the cage. The distance L4 between the surrounding frames adjacent to the uppermost surrounding frame and the bottom surface of the suspension cage body is at least 1.3 m. The safety of high-altitude operation is considered, and people cannot fall out of the high-altitude operation.

The suspension cage can bear the weight of a person, can meet the requirement of high-altitude operation, can ensure the safety of an operator in the operation process, is reliably connected with the truss, has a light and firm structure, is convenient to connect with the truss, and is convenient for manual operation.

Detailed Description

In the figures 1-3, the utility model adopts a suspension cage body formed by welding steel bars. The utility model comprises the following components: the number of the enclosure frames 1 is 4, and the number of the connecting ribs 5 is 4. The two connecting ribs 5 are symmetrically arranged along the symmetrical center plane of the width direction of the suspension cage at a distance of 0.5 m. The two connecting ribs 5 are symmetrically arranged along the symmetrical center plane of the length direction of the suspension cage at a distance of 0.6 m. The enclosure frame 1 is uniformly arranged outside the connecting ribs 5 from top to bottom along the Z direction. The external dimension (length × width × height) of the cage is 1m × 0.8m × 1.5 m.

The connecting ribs 5 are L-shaped, each connecting rib 5 is composed of a horizontal section 52 and vertical sections 51 positioned at two ends of the horizontal section, and the horizontal sections of the connecting ribs are arranged along the X direction or the Y direction. A perpendicular section 51 is the long limit of splice bar 5, and long limit length is L1, and another perpendicular section 51 is the minor face of splice bar 5, and the minor face length is L2, and the long limit of splice bar 5 is equipped with 4 with the couple that the truss articulates, and the minor face of splice bar 5 is equipped with the back hook 6 of returning the head, and couple 4 and back hook 6 are outside, and couple 4 exceeds back hook 6. The enclosure frame 1 is enclosed into a rectangle by steel bars.

The uppermost enclosing frame 1 is positioned in a hook of a return hook 6 of the connecting rib 5 and is contacted with the return hook 6, the lowermost enclosing frame 1 is close to a horizontal section 52 of the connecting rib 5 and is arranged at the lower part of the connecting rib 5, and a second enclosing frame counting downwards from the upper part is preferably about 1.3m away from the bottom of the suspension cage body. The bottom of the suspension cage body is provided with a wood plate, so that an operator can stand conveniently. The height of the third enclosure frame from the top down is preferably designed in such a way that an operator does not slide out of the middle of the rib 5 when standing on the wood board at the bottom of the cage body.

The operator stands on cage body bottom plank, when needs operate the outer equipment of cage (if installation, welding, adjustment, polish, local brush coating), the operator is from last down first second enclose the operation outside the cage of upper part of the body between the frame, because of from last down the second enclose the frame apart from cage body bottom plank face distance L4=1.3m, the frame is enclosed to last down second above operator's the chest this moment, is difficult to drop, but both hands can operate outside the cage. In the suspension cage body, the distance L3=1.5m between the upper first enclosure frame and the surface of the wood board at the bottom of the suspension cage body is normal, and an operator is less prone to coming out of the cage.

As shown in figure 4, the lifting cage body is hung by using beams at 90-degree lifting points of the trusses 9, so that the lifting cage body is stable and reliable, bears force in two directions and is reliable to mount.
