Abstract
The utility model discloses an externally-pressed manhole cover of a bulk cement truck. The manhole cover disclosed by the utility model comprises a barrel body and a round connecting plate fixed at the external wall of the barrel body, wherein one side of the connecting plate is provided with a safety buckle, and the other side of the connecting plate is provided with a support capable of moving up and down; the connecting plate is radially and slidably provided with three hinge seats which are respectively hinged with a press plate; a cover plate is buckled in the barrel body; one side of the cover plate is hinged on the support, and the other side of the cover plate is provided with a U-shaped frame; the U-shaped frame is buckled by the safety buckle; a rotating shaft is rotatably arranged at the center of the cover plate in a screwing manner; a sleeve is screwed on the rotating shaft; the external wall of the sleeve is provided with press blocks matched with the three press plate; and the upper end of the rotating shaft is fixedly provided with a handle. The manhole cover disclosed by the utility model has the advantages that the structure is simple; the connecting plate is radially and slidably provided wit the hinge seats, and the press plates are hinged on the hinge seats, so that the favorable air tightness of the cover plate is ensured.
Description
Technical field:
The utility model relates to bulk cement tanker and makes the field, relates in particular to a kind of bulk cement tanker external pressure manhole cover.
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 to the external pressure manhole cover has higher requirement, and the external pressure manhole cover is again to charging hole and access opening, needs switch conveniently, flexibly.But because the external pressure manhole cover structure design of original bulk cement carrier is unreasonable, the leak tightness of external pressure manhole cover is relatively poor after the long-term use.
The utility model content:
In order to remedy the deficiency of prior art, the purpose of the utility model provides a kind of bulk cement tanker external pressure manhole cover, and the tightness of capping improves.
The technical scheme of the utility model is following:
Bulk cement tanker external pressure manhole cover; Comprise cylindrical shell, be fixed in the connecting panel of the circle of cylinder body outer wall; It is characterized in that: connecting panel one side is equipped with safety catch; Opposite side is equipped with the bearing of oscilaltion, and the connecting panel upper edge radially slides three hinged seats are installed, and is hinged with pressing plate respectively on three hinged seats; Fasten in the cylindrical shell cover plate is arranged; Cover plate one side is hinged to be installed on the bearing, and opposite side is provided with the U-shaped frame, and U type frame is fastened by safety catch; Screwing installation is rotated at described cover plate center has turning cylinder; Be combined with sleeve on the turning cylinder, sleeve outer wall is provided with the briquetting that matches with three pressing plates, and the turning cylinder upper end is fixed with handle.
Described bulk cement tanker external pressure manhole cover is characterized in that: be positioned at one of them a side of three pressing plates on the described cover plate and be provided with registration mast.
The utility model has the advantages that:
The utility model is simple in structure, on connecting panel, is provided with radially to be slidingly fitted with hinged seat, is hinged with pressing plate on the hinged seat, and actv. has guaranteed the cover plate good sealing property.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
Bulk cement tanker external pressure manhole cover; Comprise cylindrical shell 1, be fixed in the connecting panel 2 of the circle of cylindrical shell 1 outer wall; Connecting panel 2 one sides are equipped with safety catch 3; Opposite side is equipped with the bearing 4 of oscilaltion, and connecting panel 2 upper edges radially slide to be equipped with on 5, three hinged seats 5 of three hinged seats and are hinged with pressing plate 6 respectively; Fasten in the cylindrical shell 1 cover plate 7 is arranged; Cover plate 7 one sides are hinged to be installed on the bearing 4, and opposite side is provided with U-shaped frame 8, and U type frame 8 is fastened by safety catch 3; Screwing installation is rotated at cover plate 7 centers has turning cylinder 9; Be combined with sleeve 10 on the turning cylinder 9, sleeve 10 outer walls are provided with the briquetting 11 that matches with three pressing plates, and turning cylinder 9 upper ends are fixed with handle 12.
Be positioned at one of them a side of three pressing plates on the cover plate 7 and be provided with registration mast 13.
