Abstract
The utility model discloses a sunk type internal compression manhole cover of a bulk cement tank truck, which comprises an outer barrel body welded in a tank body, an inner barrel body and a circular connecting plate fixed between the outer barrel body and the inner barrel body, wherein a cover plate is buckled on the inner barrel body, one side of the cover plate is hinged on the connecting plate, the other side is provided with a U-shaped frame, the U-shaped frame is buckled by a safety catch installed in a corresponding position on the connecting plate, and the center of the cover plate is rotatably provided with a handle. In the utility model, because the connecting plate is connected between the inner and outer barrel bodies and the outer barrel body is welded in the tank body, the welding height is lowered; and because bosses are added at corners of arm angles and adjustable bolts are screwed on the bosses, good sealing property can still be ensured after the cover plate is used for long term.
Description
Technical field:
The utility model relates to bulk cement tanker and makes the field, relates in particular to and presses manhole cover in a kind of bulk cement tanker sunk type.
Background technology:
Bulk cement tanker is claimed bulk powder goods tanker again, partly is made up of special-purpose automobile chassis, Bulk cement Delivery Tankers, air pipe system, automatic unloading device etc.Be applicable to that particle diameters such as fly ash, cement, pulverized limestone, mineral powder, granulated alkali are not more than the transportation in bulk of 0.1mm powder dried material.Use in main cement mill, cement warehouse and the heavy construction building site of supplying, and can practice thrift a large amount of packing and loading and unloading work.
Bulk cement Delivery Tankers is mainly become by tank body, tank body upper end manhole cover (giving inlet point), fluidized-bed, discharge nozzle assembly, air inlet pipe and other enclosure group.
Through power takeoff and transmission shaft the power of car chassis is reached Air compressor.Air compressor fully mixes jar interior air and powder grain material to filling air in the jar, forms flow-like.When pressure arrives certain amount, open the discharging butterfly valve.To expect to discharge
Owing to bulk cement tanker is to lean on jar interior air pressure discharging, therefore the leak tightness for interior pressure manhole cover there is higher requirement, need switch conveniently, flexibly.But because the interior pressure manhole cover structure design of original bulk cement carrier is unreasonable, the interior leak tightness of manhole cover of pressing is relatively poor after the long-term use; The height of bulk cement tanker limits, because original interior pressure manhole cover self setting height(from bottom) is higher, thereby the capacity of tank body just receives certain restriction.
The utility model content:
In order to remedy the deficiency of prior art, the purpose of the utility model provides presses manhole cover in a kind of bulk cement tanker sunk type, reduced the height that is welded of manhole cover effectively, and the tightness of capping has improved.
The technical scheme of the utility model is following:
Press manhole cover in the bulk cement tanker sunk type; It is characterized in that: comprise outer cylinder body, the inner barrel that is welded in the tank body, the connecting panel that is fixed in the circle between outer cylinder body and the inner barrel; Fastening on the inner barrel has cover plate, and cover plate one side is hinged to be installed on the connecting panel, and opposite side is provided with U type frame; The safety catch that U type frame is installed by opposite position on the connecting panel fastens, and described cover plate center is rotatablely equipped with handle.
Press manhole cover in the described bulk cement tanker sunk type; It is characterized in that: middle part, described cover plate lower surface is welded with fixed cover, is slidingly fitted with interior cover in the fixed cover, and interior cover screwing installation is in the turning cylinder lower end of handle; Several adapter plates of outer wall of inside race rectangular distribution; Have guide groove on the adapter plate, be slidingly fitted with the angle arm in the guide groove, arm upper end in angle is articulated in the cover plate lower surface.
Press manhole cover in the described bulk cement tanker sunk type, it is characterized in that: the outside, turning of described angle arm is provided with horizontal ledge, is combined with downward bolt on the horizontal ledge, and the convexity of inner barrel was withstood in the bolt upper end when cover plate fastened.
The utility model has the advantages that:
The utility model adopts between the inside and outside cylindrical shell and is connected with connecting panel, and outer cylinder body is welded in tank body, has reduced the height that is welded, and arm corner sets up boss at the angle, is combined with adjustable bolt on the boss, makes the long-term use cover plate still can guarantee good sealing property.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the cut-away view of the utility model.
Fig. 3 is the mounting structure figure of the utility model.
The specific embodiment:
Press manhole cover in the bulk cement tanker sunk type; Comprise outer cylinder body 1, the inner barrel 2 that is welded in the tank body A, the connecting panel 3 that is fixed in the circle between outer cylinder body 1 and the inner barrel 2; Fastening on the inner barrel 2 has cover plate 4, and cover plate 4 one sides are hinged to be installed on the connecting panel 3, and opposite side is provided with U type frame 5; The safety catch 6 that U type frame 5 is installed by opposite position on the connecting panel 3 fastens, and cover plate 4 centers are rotatablely equipped with handle 7.
Middle part, cover plate 4 lower surfaces is welded with fixed cover 8; Cover 9 in being slidingly fitted with in the fixed cover 8; Interior cover 9 screwing installation are in turning cylinder 10 lower ends of handle, and interior several adapter plates 11 of cover 9 outer wall rectangular distributions have guide groove 12 on the adapter plate 11; Be slidingly fitted with angle arm 13 in the guide groove 12, arm 3 upper ends in angle are articulated in cover plate 4 lower surfaces.
The outside, turning of angle arm 13 is provided with horizontal ledge 14, is combined with downward bolt 15 on the horizontal ledge 14, and the convexity 16 of inner barrel 2 inwalls was withstood in bolt 15 upper ends when cover plate 4 fastened.
