Abstract
The utility model relates to a hole cover in an asphalt mixture stirring housing, especially a manhole cover with an eccentric handle. According to the technical scheme provided in the utility model, the manhole cover with an eccentric handle comprises a manhole arranged on the housing and a manhole cover body covering on the manhole, characterized in that an eccentric mechanism is arranged on a position corresponding to the manhole on the housing, an eccentric pipe in the eccentric mechanism is arranged above the manhole cover body, the eccentric pipe can be rotated to press on the manhole cover body. The utility model has simple structure, convenience for installation and detachment, and long service life.
Description
Technical field
The utility model relates to the port lid on a kind of bituminous mixture stirring shell, especially a kind of manhole cover that has eccentric handle.
Background technology
In the bituminous mixture stirring shell, all need to reserve manhole on many parts, so that inspection in the use and maintenance.Manhole commonly used has various ways such as hinge type and bolt connection, but because manhole cover generally is to be exposed in the air, be subjected to behind rainwater and the easy oxidation and rusting of effect of dust hinge stuckly, make access door not open, and install and cumbersome during dismounting with bolted manhole cover.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of manhole cover is provided, and it is simple in structure, and long service life is installed and convenient disassembly.
The technical scheme that provides according to the utility model, the described manhole cover that has eccentric handle, comprise and be arranged at the manhole on the housing and cover manhole cover body on manhole, it is characterized in that: the position corresponding to manhole on described housing is provided with eccentric stiffener, eccentric pipe in the described eccentric stiffener is positioned at the top of manhole cover body, after rotating eccentric pipe, described eccentric pipe can be pressed on the described manhole cover body.
In described eccentric stiffener,, between described bearing pin and the eccentric pipe eccentric distance e is arranged at the fixedly connected bearing pin of the inwall of eccentric pipe; The fixedly connected handle that rotates eccentric pipe that is useful on eccentric pipe; The end and the support of described bearing pin are rotationally connected, and described support is installed on the described housing.Described manhole cover body is provided with handle.A side of facing manhole at described manhole cover body is provided with ring washer.
Advantage of the present utility model: simple in structure, easy to make, long service life is installed and convenient disassembly.
Description of drawings
Fig. 1 is the utility model user mode figure.
Fig. 2 is the lateral view of Fig. 1.
Fig. 3 is the A-A sectional view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
Shown in Fig. 1,3: as described in have the manhole cover of eccentric handle, comprise and be arranged at the manhole on the housing and cover manhole cover body 1 on manhole, it is characterized in that: the position corresponding to manhole on described housing is provided with eccentric stiffener, eccentric pipe 4 in the described eccentric stiffener is positioned at the top of manhole cover body 1, after rotating eccentric pipe 4, described eccentric pipe 4 can be pressed on the described manhole cover body 1.
In described eccentric stiffener,, between described bearing pin 3 and the eccentric pipe 4 eccentric distance e is arranged at the fixedly connected bearing pin 3 of the inwall of eccentric pipe 4; The fixedly connected handle 5 that rotates eccentric pipe 4 that is useful on eccentric pipe 4; The end of described bearing pin 3 and support 2 are rotationally connected, and described support 2 is installed on the described housing.
Described manhole cover body 1 is provided with handle 6.A side of facing manhole at described manhole cover body 1 is provided with ring washer 7; Corresponding to being provided with the band steel circle around the manhole, described band steel circle, covers described band steel circle when manhole cover body 1 covers on manhole less than described manhole cover body 1 on described housing.
During making, on the housing of plant equipment, offer manhole as requested, be welded with the band steel circle at tapping, the aperture of described band steel circle is identical with the manhole pore size, the ring washer 7 corresponding assemblings on described band steel circle and the described manhole cover body 1.According to the pore size of manhole, welding support 2 on the housing of described manhole both sides, described bearing pin 3 and support 2 corresponding assemblings.After described bearing pin 3 and the support 2 corresponding assemblings, the ring washer 7 on the manhole cover body 1 can corresponding assembling with the band steel circle on being welded on manhole.Under the positioning action of support 2, press down handle 5, drive eccentric pipe 4 and turn to the eccentric distance e maximum around the axle center of bearing pin 3, manhole cover body 1 and the band steel circle that is welded on the housing are compressed.When needs field-strip port lid body 1, upwards pull handle 5, eccentric distance e diminishes, and manhole cover body 1 breaks away from band steel circle on the housing, by handle 6 field-strip port lid body 1 easily.
