Description
Technical field
The utility model belongs to a kind of fire-fighting equipment, specifically, more particularly to it is a kind of can automatically unloading fire-fighting truck tank
Body cover.
Background technology
GB7956.2-2014《Fire fighting truck part 2 triple》4.4.3.1.4 it is required that：" volume is more than 1m3Tank
Top should set the manhole and manhole cover for being available for personnel to pass in and out, and people's bore dia is not less than 400mm, and manhole cover exceedes in pressure inside the tank
Can automatically unloading during 0.1MPa." at present, the tank body cover commonly used on fire fighting truck is primarily present following shortcoming：1st, mechanical fixed-type external
Structure, show as tank mouth, cover, to be fixedly connected with mechanism etc. directly fixed, it is impossible to automatically unloading is realized, it is how independent using installing additional
Pressure relief device realizes pressure relief, but the phenomenon for occurring release because pressure relief device flow restriction etc. more and damaging tank body not in time；2、
Cover body and bindiny mechanism use cast type structure, and weight is larger, inconvenient for operation；3rd, cover can not realize accurate release；
4th, sealing of tank cover uses U-shaped sealing ring, easy to fall off after being contacted for a long time with medium in tank.
Utility model content
The utility model purpose be to provide it is a kind of improve simple operation can automatically unloading fire engine tank cover,
With overcome in the prior art fire engine tank occur the defects of obvious residual deformation not in time because being unable to release or release.
The utility model is realized using following technical scheme：It is a kind of can automatically unloading fire engine tank cover,
Including cover body, tank mouth, the cover body upper part is provided with upper bracket, and the both ends of the upper bracket by fixed plate A and are consolidated
Fixed board B is connected with tank mouth, passes through the nut through lead thereon and on lead and cover sheet among upper bracket
Body connects, and the lead is provided with preloading spring.
The fixed plate A is hinged with clamping screw, and the clamping screw top connects rotary handle, described upper bracket one end
It is hinged with fixed plate B, the other end is connected by connecting prong with clamping screw and rotary handle.
The cover body uses stamping parts structure.
The tank mouth edge uses vertical eversion type structure.
The tank mouth edge is provided with L-type sealing ring.
Compared with prior art, the beneficial effects of the utility model are：(1) the utility model is simple in construction, can be accurately real
The pretension of existing cover and release, improve simple operation；(2) cover body uses stamping parts structure, greatly reduces cover certainly
Weight, improves simple operation, pressure relief is sensitiveer；(3) sealing ring fixation, sealing ring and medium in tank are avoided
Long Term Contact bonds obscission.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, it is a kind of can automatically unloading fire engine tank cover, including cover body 8, tank mouth 9,
The top of cover body 8 is provided with upper bracket 4, and the both ends of upper bracket 4 are connected by fixed plate A1 and fixed plate B11 with tank mouth 9, upper branch
By being connected through lead 7 thereon and the nut on lead 76 with cover body 8 among frame 4, with cover sheet
Upper bracket 4 and cover body 8 are connected as a single entity by lead 7 and upper dress round nut 6 based on body 8, are furnished with lead 7
Preloading spring 5, preloading spring 5 carries certain pretightning force during assembling, and cover body 8 and upper bracket 4 is whole when ensureing to open cover
Body.Fixed plate A1 is hinged with the lower end of clamping screw 2, the top of clamping screw 2 connection rotary handle 3, the one end of upper bracket 4 and fixation
Plate B11 is hinged, and the other end is connected by connecting prong 12 with clamping screw 2 and rotary handle 3.Clamping screw 2 is convex platform spiral shell
Line structure, by rotary handle 3, pre- tightening seal is carried out to tank mouth 9.
Cover body 8 uses stamping parts structure, greatly reduces cover body 8 and conducts oneself with dignity, improves simple operation, release
Function is sensitiveer.
The utility model tank mouth 9 uses vertical eversion type structure, is equipped with corresponding L-type sealing ring 10, can effectively realize sealing
10 fixing seals are enclosed, while avoids sealing ring 10 and bonds obscission with medium Long Term Contact in tank.
It pressure request unloaded according to national standard with spring computational methods combination cover sectional area can calculate preloading spring 5 and press
Contracting length, so that it is determined that the upper boss reach of clamping screw 2, being equipped with corresponding lead 7 can realize that cover body 8 is accurate
Pretension and release, into tank when reaching when unloading pressure pressure of standard requirement in injection process, preloading spring 5 compresses, and then realizes
Cover release, be up to state standards requirement.
