Background

The folding cover plate is equipment frequently used on various large-scale hanging holes, and the conventional hanging hole folding cover plate mainly comprises a frame, a bottom plate, a balance arm, a hinge seat, a bearing and a track at present. The hinge seat is connected with two bottom plates, wherein one bottom plate (namely one folding cover plate) moves on the track by being attached to a shaft supported by the shaft and a roller, so that the bottom plates are opened and closed. The height of the position where the shaft support is welded with the bottom plate is usually determined by rotation of a design drawing, the height obtained by rotating the bottom plate has deviation from the actual manufacturing, the position of the shaft support and the position of the bearing are adjusted by repeatedly trying to pull the bottom plate in the manufacturing process, and the shaft support is welded and fixed when the position is adjusted to a proper position. When the folding cover plate is used for a hanging hole with a larger size, the frame of the cover plate and the bottom plate must be disassembled to be transported to the site. But because structural not enough, accumulative error often can appear when on-spot tailor-welding apron frame and equipment bottom plate, leads to on the bottom plate gyro wheel (bearing) can't normally move on the track, not only hard when opening the bottom plate, can't keep the vertical state after the bottom plate is opened moreover, installer must demolish the axle and support, tries to draw the bottom plate repeatedly and comes the adjusting spindle support position, not only wastes time and energy, can increase the engineering volume moreover. Therefore, the shaft support adjusting mechanism on the bottom plate is a technical problem which needs to be solved.

Detailed Description

The following detailed description of the embodiments of the utility model is provided in connection with the accompanying drawings and the detailed description.

The adjusting mechanism applied to the bearing on the folding cover plate comprises shaft supports and rollers, wherein 2 shaft supports 3 are arranged at intervals, one end of each shaft support 3 is arranged on a cross beam 1 of the folding cover plate, symmetrical through holes 7 are formed in the 2 shaft supports, transverse roller shafts 5 are arranged in the through holes 7, locking adjusting devices 9 are arranged on the roller shafts 5 extending out of the through holes 7 on the left side, rollers 4 are arranged on the roller shafts 5 extending out of the through holes 7 on the right side through holes through bearings, connecting plates 6 are welded between opposite surfaces of the 2 shaft supports 3, and adjusting devices are arranged on one ends of the connecting plates 6 and connected with the roller shafts 5 and used for adjusting the positions of the roller shafts 5 in the through holes 7.

In order to ensure better implementation effect, the locking adjusting device 9 is a nut which is in threaded connection with the roller shaft 5, and the outer diameter of the nut is larger than the diameter of the through hole 7 and is used for adjusting the length of the roller shaft 5 extending out of the left side.

The adjusting device comprises a screw rod 2, a first nut 8 and a second nut 8-1, one end of the screw rod 2 penetrates through the connecting plate 6 and is fixed with the outer side of the connecting plate 6 through the second nut 8-1, the other end of the screw rod penetrates through the roller shaft 5 along the diameter direction of the roller shaft 5, and the first nuts 8 used for adjusting and fixing the screw rod are arranged on two sides of the screw rod 2 through which the roller shaft 5 penetrates.

The shaft support 3 is a whistle-shaped integrated structure formed by a square plate at the upper part and a long circular plate at the lower part, the upper part of the square plate is welded with the cross beam 1, the central sections of the square plate and the long circular plate are L-shaped, the long circular plate is provided with a through hole 7, and the two ends of the connecting plate 6 are welded on the long circular plate above the through hole 7.

The outer diameter of the roller shaft 5 is 4-5mm smaller than the inner diameter of the through hole 7.

When the utility model is used in concrete, the beam 1 is arranged on a bottom plate at the outermost side of the folding cover plate, after the position of the folding cover plate is determined, the roller 4 is required to be arranged on the track to ensure that the folding cover plate can be opened and closed normally, according to the actual requirement, firstly, the locking adjusting device 9 is screwed to adjust the length of the roller shaft 5 extending out of the left side, i.e. to ensure that the roller 4 is in the correct position on the rail in the horizontal direction, when the position of the roller 4 on the rail is adjusted to the left and right (left and right with respect to figures 1 and 2), then adjusting the upper and lower positions of the roller 4 on the track, screwing the first nut 8, adjusting the position of the roller shaft 5 in the through hole 7 to ensure that the roller 4 is positioned at the correct position of the track in the vertical direction, the first nut 8 is then tightened to secure the roller shaft 5, and the position of the roller 4 is adjusted to optimize opening and closing of the foldable cover (as in the prior art).
