One end is fixed in upper capping by bearing pin A, by the driving of hydraulic stem, can be opened into upper capping greatly by horizontal closed mode
In 90 degree of position.
The skeleton of box girder construction is provided with described upper capping, and has gusset in skeleton intermediate arrangement.
Safety pin is fixed with by chain on described lower free bearing.
Described lower free bearing end is provided with pin-and-hole；Described upper twisted seat end is provided with pin-and-hole, when upper capping is opened into 90 degree
When, the pin-and-hole alignment on upper twisted seat and lower free bearing, and it is spacing using safety pin.
Limit spacing at two is set in the control system of described hydraulic stem, upper capping closed mode and upper envelope are corresponded to respectively
Lid maximum open position.
Described hydraulic stem is in the horizontal closed mode of upper capping and the angle of horizontal plane is 41 degree, and hydraulic stem is in upper capping
When being opened into 90 degree and the angle of horizontal plane is 36.4 degree.
Remarkable result of the present utility model is：A kind of envelope for test chamber upper box described in the utility model
Lid, optimizes the structure of capping, is used in combination force structure and non-stress structure, alleviates weight and malformation；Together
When, opened and closed and covered on upper box using the hydraulic system of mechanism on test section in itself, it is easy to operated, not only time saving but also province
Power；Triple protection measure is employed, in hydraulic system there is provided limit spacing at two, and in upper capping maximum open position up and down
There is provided mechanical position limitation and being provided with safety pin at free bearing, the safety coefficient that capping is opened and closed is added.
