Description
Technical Field
The utility model relates to a cover plate, in particular to a bottom plate sectional type safe labor-saving cover plate.
Background
The dam gate notch that builds at present adopts concrete apron or fixed steel apron mostly, and the lift beam buttress top surface of gate is in same height with the dam facing, and the gate needs to be put up when the dam facing, need lift the roof beam to support, lifts the roof beam and falls on the dam facing this moment, but when the installation of conventional safe laborsaving apron, the frame of apron can influence each other with lifting the roof beam, has brought huge degree of difficulty for later stage transformation safe laborsaving apron. In order to meet the bearing requirement and the strength of the bottom plate, the bottom plate and the frame are integrally welded and formed by adopting root-passing materials, but if the conventional safety labor-saving cover plate is to be installed at a gate notch, a lifting beam of a gate needs to be arranged below a dam face, and the conventional method is to excavate a supporting plane of a platform beam downwards so that the supporting plane of the lifting beam is lower than the dam face. But the guide rail with the gate on the vertical surface of the beam-lifting buttress cannot be excavated. Therefore, a bottom plate sectional type cover plate needs to be designed, so that the lifting beam can work normally and the cover plate can be opened and closed normally, but the disclosure and the report are not made up to the present.
Disclosure of Invention
Aiming at the situation, the utility model aims to overcome the defects of the prior art, and aims to provide the bottom plate sectional type safe labor-saving cover plate, which can effectively solve the problem that a lifting beam and the cover plate at a gate notch of a dam can be mutually influenced.
In order to achieve the above purpose, the utility model solves the technical scheme that the base plate sectional type safe labor-saving cover plate comprises a base plate and a frame, wherein the frame is arranged around a lifting opening, the base plate comprises a first movable base plate, a second movable base plate, a third movable base plate and a fixed base plate, the first movable base plate and the third movable base plate are arranged in two ends of the frame, a second movable base plate with two ends in a convex shape is arranged in the frame between the first movable base plate and the third movable base plate, and a first fixed base plate and a second fixed base plate which are symmetrical are respectively arranged in the frame between the two ends of the second movable base plate and the first movable base plate and the third movable base plate, so that the sectional type safe labor-saving cover plate which is alternately arranged in a movable mode and a sectional mode is formed.
The lifting beam can be always placed on the cover plate, and meanwhile, the bearing and the strength of the cover plate are not affected when the cover plate is opened and closed, so that the mounting problem of the cover plate is solved, and good social and economic benefits are achieved.

Detailed Description
The following detailed description of specific embodiments of the utility model refers to the accompanying drawings and the detailed description.
The utility model provides a base plate sectional type safe and labor-saving cover plate, which is provided with a frame and comprises a base plate and a frame, wherein the frame is arranged around a lifting opening, the safe and labor-saving cover plate is characterized in that the base plate comprises a first movable base plate 5, a second movable base plate 2, a third movable base plate 4 and a fixed base plate, the first movable base plate 5 and the third movable base plate 4 are arranged in two ends of the frame 1, the second movable base plate 2 with two ends in a convex shape is arranged in the frame 1 between the first movable base plate 5 and the third movable base plate 4, and the first fixed base plate 3 and the second fixed base plate 7 which are symmetrical are respectively arranged in the frame 1 between the two ends of the second movable base plate 2 and the first movable base plate 5 and the third movable base plate 4, so that the sectional type safe and labor-saving cover plate which is alternately arranged in a movable mode is formed.
In order to ensure better implementation effect, the first fixed bottom plate 3 and the second fixed bottom plate 7 have the same structure, the first fixed bottom plate 3 is in a shape of a concave, the concave surface of the concave is matched with the convex surface of the end part of the second movable bottom plate 2, and the lifting beam 6 is arranged on the connecting part 301 of the concave.
The inner surfaces of the two ends of the second movable bottom plate 2 are provided with bolts, the corresponding first movable bottom plate 5 and the third movable bottom plate 4 are provided with bolt sleeves, and when the first movable bottom plate 5, the second movable bottom plate 2 and the third movable bottom plate 4 are opened, the two ends of the second movable bottom plate 2 are connected with the first movable bottom plate 5 and the third movable bottom plate 4 through the bolts 9.
In the concrete production process, the conventional bottom plate is divided into five sections, wherein three sections are movable bottom plates (namely, the bottom plates which can be opened and closed), two sections are fixed bottom plates (namely, the bottom plates which can be always kept in a closed state), the first fixed bottom plate 3 and the second fixed bottom plate 7 are arranged among the first movable bottom plate 5, the second movable bottom plate 2 and the third movable bottom plate 4, and the widths of the first fixed bottom plate 3 and the second fixed bottom plate 7 are determined according to the moving distance of the lifting beam 6 for throwing and withdrawing (namely, left and right movement). After the cover plate is installed, the input and the withdrawal of the lifting beam 6 are carried out on the fixed bottom plate, the contact area of the lifting beam 6 is increased, and the first fixed bottom plate 3 and the second fixed bottom plate 7 are arranged on the original plane of the lifting beam buttress for placing the lifting beam 6, so that the bearing of the gate is not influenced by the closed state. The supports of the first fixed bottom plate 3 and the third movable bottom plate 4 respectively fall on the frame and the fixed bottom plate, and the second movable bottom plate 2 adopts an inclined support as a bearing support.
When the fence is specifically used, after the cover plate is opened to form the fence, a gap can appear at the position of the lifting beam 6, and the fence is connected together through the plug 9 at the moment to seal the gap, so that the cover plate can still form a complete fence after being opened. After the fence is formed, the gate 8 needs to be erected on the dam surface, at this time, the 2 lifting beams 6 are respectively moved to the input positions, namely, the protruding parts 302 at the two ends of the concave shape of the fixed bottom plate, the gate is erected, when the gate is put down, after the cover plate is required to be closed, the lifting beams 6 are respectively moved to the exit positions, namely, the upper surfaces of the connecting parts 301 of the concave shape of the fixed bottom plate, at this time, the movable cover plate can be normally closed and cannot be influenced.
The utility model has simple structure, scientific and reasonable design, easy production and manufacture, convenient use, wide application and good social and economic benefits, and can always be placed on the cover plate, and meanwhile, the bearing and the strength of the cover plate can not be influenced when the cover plate is opened and closed, so that the mounting problem of the cover plate is solved.
