Problems solved by technology

[0002] The cover plate of the existing manhole cover is generally a cast iron cover plate, because the cast iron cover plate itself is relatively heavy, and the staff has no protective measures when opening and closing, so once the cover plate slips by mistake, it is very easy to cause personal injury to the operator, so there is a need for improvement

Embodiment Construction

[0019] The following are specific embodiments of the present invention in conjunction with the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0020] Such as figure 1 with figure 2 As shown, a manhole cover support structure of the present invention includes a manhole 1. The manhole 1 includes a front panel 11 and a rear panel 12 parallel to each other. The upper cover of the manhole 1 is hinged with the rear panel 12 through a hinge. The bottom surface of the cover 2 is close to the front wall 11 and is provided with a hinge 21. It also includes a support frame 3 with a triangular frame structure. The support frame 3 includes three triangular-connected frame rods 31 and three triangular-connected rods. Frame rod two 32, two mutually parallel support rods 33, and a rotating shaft 34 parallel to the support rod 33. The support frame 3 is hinged on the hinge part 21 through...

Abstract

The invention provides a manhole cover support structure, which belongs to the field of ship equipment. It solves the problem that the existing manhole cover lacks support and is easy to cause danger. The supporting structure of the manhole cover includes a manhole. The manhole includes a front wall and a rear wall. The manhole is covered with a cover plate hinged with the rear wall through a hinge. Including a triangular frame structure support frame, the support frame includes three triangularly connected frame rods one, three triangularly connected frame rods two, two mutually parallel support rods and a rotating shaft parallel to the supporting rods, the supporting frame is hinged on the On the hinged part, and the rotating shaft is parallel to the cover plate and the dash panel, and the supporting frame can be turned out around the rotating shaft, so that a support rod is pressed against the bottom surface of the cover plate, and a support rod 1 and a support rod 2 are supported On the front wall, the support frame can also be turned inward around the rotating shaft, so that another support rod is pressed against the bottom surface of the cover plate. The cover of the personal hole can be supported by the support frame to prevent the cover from being accidentally closed.

Description

Technical field [0001] The invention belongs to the technical field of ship equipment and relates to a manhole cover supporting structure. Background technique [0002] The cover plate of the existing manhole cover is generally cast iron cover plate, because the cast iron cover plate itself is relatively heavy, and the staff does not have protective measures when opening and closing, so once the cover plate slips off, it is easy to cause personal injury to the operator, so It is necessary to improve. Summary of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems in the prior art and provide a manhole cover supporting structure that can provide support when the cover is opened and avoid accidents. [0004] The purpose of the present invention can be achieved by the following technical solutions: a manhole cover supporting structure, including a manhole, the manhole includes a front panel and a rear panel that are parallel to each othe...
