Description
Technical Field
The utility model relates to a mechanical connecting device especially relates to a two-sided removable tower tray board and backup pad connecting device.
Background
In the industries of chemical industry, oil refining, energy, light industry, pharmacy, environmental protection and the like, tower equipment is often used in heat and mass transfer production processes of rectification, absorption, extraction, gas humidification, cooling, drying and the like. According to different technological requirements, the types of the tower tray plates of the internal parts of the tower equipment are different, when the diameter of the tower is more than or equal to 800mm, the convenience of manufacturing, installing and overhauling of the tower tray is considered, and the whole tower tray plate is generally made into a sectional type tower tray plate and is sent into the tower through a manhole. At present, the tower tray plates in the industry are connected by a threaded clamp plate fastener connecting structure or wedge connection. The screw thread cardboard fastener structure is that screw thread and cardboard weld into a whole, when screwing up the nut, through oval backing plate and cardboard, fastens the tray board on the support ring. Because the bolt of the threaded clamp plate fastener is made of special steel (stainless steel), the processing amount is large, the manufacturing cost is high, and the assembly and disassembly are troublesome, the use is gradually reduced in China at present; the gantry wedge fastener has the characteristics of simple structure, easiness in manufacturing, convenience in assembly and disassembly, capability of saving stainless steel, no need of special steel (only Q235-AF material), welding during installation, hammering during disassembly, wide application in China at present, but inapplicability to inflammable and explosive media with strong corrosivity.
Disclosure of Invention
An object of the utility model is to provide a two-sided removable tray board and backup pad connecting device, the utility model discloses replace the cardboard with the dysmorphism backing plate below the tray board, the structure is simpler, can realize two-sided can dismantle, simple structure, easy dismounting, the installation and the maintenance of being convenient for.
The utility model aims at realizing through the following technical scheme:
a double-sided detachable tray plate and supporting plate connecting device comprises a stud, a nut, a special-shaped base plate, a tray plate, a supporting plate and a filler strip; the stud penetrates into the circular hole of the supporting plate, the special-shaped base plate and the lower nut are screwed on the stud from the lower part, the fixed tower plate is placed at the specified position of the supporting plate and is pressed by the special-shaped base plate, and then the tower plate is tightened by screwing the nut; the outer cylindrical surfaces of the upper section and the lower section of the bolt are respectively milled with a plane, so that the section of the bolt is arched, and the bolt hole of the special-shaped base plate is also arched and can be just sleeved on the bolt; round holes are formed in the supporting plate; the supporting plate is additionally provided with a strip pad, so that the two plates are exactly positioned on the same horizontal plane.
According to the connecting device for the double-sided detachable tray plate and the supporting plate, the tray plate is fastened on the supporting plate by the fastening stud and the special-shaped base plate.
The double-sided detachable tray plate and support plate connecting device is characterized in that the special-shaped plate sleeved on the stud is fixedly arranged with the stud.
The utility model has the advantages and effects that:
the utility model discloses a stud fastener structure compares with traditional double-screw bolt nut-oval backing plate-cardboard connection structure, and this connection structure can realize two-sidedly can dismantle, simple structure, easy dismounting, convenient to install and overhaul.
Drawings
FIG. 1 is a double-sided detachable connection structure diagram of a tray plate and a supporting plate;
FIG. 2 is a top view of a double-sided detachable connection structure of a tray plate and a supporting plate;
FIG. 3 is a detail view of the shaped pad;
FIG. 4 is a drawing of a connecting stud feature.
The components in the figure: the device comprises a stud 1, a nut 2, a special-shaped base plate 3, a tower plate 4, a supporting plate 5 and a filler strip 6.
Detailed Description
The present invention will be described in detail with reference to the embodiments shown in the drawings.
The utility model discloses the fastener comprises double-screw bolt nut, special-shaped backing plate and filler strip, respectively mills out a plane at the outer face of cylinder of bolt upper and lower section, makes its cross-section be bow-shaped, and the bolt hole of special-shaped backing plate also opens into bow-shaped to just in time can overlap on the bolt. Round holes are formed on the supporting plate. In order to keep the horizontal working state of the special-shaped base plate, a strip pad is additionally arranged on the supporting plate, so that the two plates are just positioned on the same horizontal plane. Compare with traditional screw thread cardboard fastener structure, replace the cardboard with special-shaped backing plate below the tower tray board, the structure is simpler. The tower plate is fastened on the supporting plate by the fastening stud and the special-shaped base plate, the special-shaped plate sleeved on the stud cannot rotate relative to the stud, the nut can be loosened from the upper side of the tower plate and the lower side of the tower plate, and after the nut is loosened, the special-shaped base plate can be removed from the tower plate only by rotating the stud by 90 degrees. When the tower is installed and overhauled, people can pass through a plurality of layers (8-10 layers) of tower tray plates in the tower from top to bottom (because a manhole cannot be arranged on the tower body between every two layers of tower tray plates), the tower can be detached from the upper part of the tower tray plate and also can be detached from the lower part of the tower tray plate, namely, the tower can be detached from the upper part and the lower part of the tower tray plate, and thus, the maintenance and the installation are greatly convenient. Considering that the fasteners are soaked in the medium for a long time, each fastener is made of stainless steel for convenient disassembly and assembly. For the carbon steel tower plate, the special-shaped base plate, the backing strips and the nuts are made of Q235-AF, and the studs are made of 2Cr13 material; for the stainless steel tray plate, except for Cr17 for the nut, 0 Cr18Ni9Ti material is used.
When the fixing device is installed, the stud penetrates into the circular hole of the supporting plate, the special-shaped base plate and the lower nut are screwed on the stud from the lower part, the tower plate to be fixed is placed at the specified position of the supporting plate and pressed by the special-shaped base plate, and then the nut is screwed, so that the tower plate is fastened. When the special-shaped base plate is disassembled, the screw bolt can be rotated only by unscrewing the nut from any surface, the special-shaped base plate is removed, and the tower plate is taken down.
