Abstract
The invention relates to an automobile gas pipe fixing assembly comprising a hard pipe. Two buckle covers with ]-shaped cross sections are arranged in the hard pipe in a sliding manner, the concave parts of the two buckle parts are opposite to each other, one of the buckle covers is movably inserted into the other buckle cover to form a clamping space used for clamping a gas pipe group wrapped by a heat insulation layer, guide rails are arranged on the inserting parts of the two buckle covers, and the buckle covers all extend along the lengthwise direction of the hard pipe; and the invention also relates to a passenger car. According to the automobile gas pipe fixing assembly and the passenger car, gas pipes are bound together, fixed clamps for the gas pipes are eliminated, so that the size of a seamless rectangular steel pipe can be designed to be extremely small, further the mounting space is reduced, when the pipes are maintained in the later period, only the buckle covers and the gas pipe group wrapped by the heat insulation layer need to be drawn out of the seamless rectangular steel pipe on a roof, so that the operation is extremely convenient, and the problems that the gas pipe fixing structure occupies a large space, and leakage oil can enter carriage easily in the prior art can be solved.
Description
Technical field
The present invention relates to a kind of vehicle fuel pipe fixation kit, the invention still further relates to have this combustion gas its have prevent gas leakage to the manned compartment, installation and maintenance make things convenient for, little advantage takes up room.
Background technology
Along with the application of LNG passenger vehicle, a kind of structure that the LNG gas cylinder is installed in the top is because gas cylinder is higher apart from ground, and the car load safety performance is better; Progressively used in LNG passenger vehicle field; The combustion gas of this LNG passenger vehicle need be passed down through liquid feeding panel and the engine charge position that passenger zone arrives the chassis from roof, and the temperature of LNG is extremely low in the gas cylinder, passes the pipe section of passenger zone and must wrap up thermal insulation layer and attachment point is arranged; Existing Gas Pipe fixed sturcture is as shown in Figure 1; Comprise relative combustion gas protecting jacket loam cake of recess 1 and Gas Pipe protecting jacket lower cover 2, Gas Pipe protecting jacket lower cover 2 inserts in the Gas Pipe protecting jacket loam cake 1, and fixing through screw 6; The cavity of Gas Pipe is held in formation, also is provided with the clamp 5 that is used for fixing the Gas Pipe 3 of wrapping up heat-insulation layer 4 on the inwall of Gas Pipe protecting jacket lower cover 2.But it is big that existing Gas Pipe fixed sturcture takies vehicle body space, will the covers of combustion gas protecting jacket be taken apart in the time of maintenance; Very inconvenient, simultaneously, there is the slit between the covers of combustion gas protecting jacket; In case Gas Pipe is leaked, combustible gas is known from experience the entering compartment, and potential safety hazard is big.
Summary of the invention
The object of the present invention is to provide a kind of vehicle fuel pipe fixation kit, take up room big and exist gas leakage to be prone to get into the problem in compartment to solve in the prior art Gas Pipe fixed sturcture, the present invention also provides a kind of passenger vehicle.
In order to address the above problem; A kind of vehicle fuel pipe fixation kit of the present invention; This assembly comprises that it is rectangle or foursquare stereoplasm tube that two ends are respectively applied for the cross-sectional plane that is fixed on compartment top board and the cabin floor; Slide in this stereoplasm tube be provided with two cross-sectional planes for the buckle closure of shape, two said buckle closure recesses in opposite directions, the movable insertion of one of them buckle closure is formed for the grasping part of clamping by the Gas Pipe group of heat-insulation layer parcel in another buckle closure; The Plug Division of two said buckle closures has guide rail, and said buckle closure all extends along the stereoplasm tube longitudinally.
Said stereoplasm tube is the seamless rectangular steel pipe.
A kind of passenger vehicle; The fixation kit that comprises compartment and vehicle fuel pipe; This assembly comprises that it is rectangle or foursquare stereoplasm tube that two ends are respectively applied for the cross-sectional plane that is fixed on compartment top board and the cabin floor; Slide in this stereoplasm tube be provided with two cross-sectional planes for the buckle closure of shape, two said buckle closure recesses in opposite directions, the movable insertion of one of them buckle closure is formed for the grasping part of clamping by the Gas Pipe group of heat-insulation layer parcel in another buckle closure; Be provided with the Gas Pipe group of parcel heat-insulation layer in the grasping part; Said buckle closure and heat-insulation layer extruding heavy keying fit and under the elastic force effect of this heat-insulation layer and said stereoplasm tube tube wall roof pressure heavy keying fit, the Plug Division of said buckle closure has guide rail, and said buckle closure all extends along the stereoplasm tube longitudinally.
Said stereoplasm tube is the seamless rectangular steel pipe.
The present invention extracts two buckle closures out stereoplasm tube earlier when installing and fixing Gas Pipe, clamp the Gas Pipe group by multi-layer heat preserving layer parcel; Then buckle closure is inserted stereoplasm tube, in the seamless rectangular steel pipe, be extruded tightly roof pressure buckle closure and buckle closure tightly withstood on the inwall of seamless rectangular steel pipe of heat-insulation layer release portion elastic potential energy; Realize Gas Pipe group fixing in the seamless rectangular steel pipe, this fixed form bundles Gas Pipe, has saved the Gas Pipe fixation clamp; Therefore the size of seamless rectangular steel pipe is can design-calculated very little, thereby has reduced installing space, when the later period maintenance pipe; Only need extract buckle closure out the seamless rectangular steel pipe together with the Gas Pipe group of in-to-in heat-insulation layer parcel at roof can be very convenient; Compare with the pipe fitting fixed sturcture of prior art, this Gas Pipe fixation kit compact conformation, it is little to take up room; Easy to maintenance; And can prevent to reveal gas and get into the compartment, safety is good, has solved in the prior art Gas Pipe fixed sturcture and has taken up room big and exist gas leakage to be prone to get into the problem in compartment.
