Underground transport trolley based on hydro pneumatic suspension of the present utility model, the specific embodiment that it is preferable such as Fig. 2, shown in Figure 3:
Comprise upper bracket, lower bracket, described upper bracket is fixed on the bottom, compartment, and described lower bracket is fixed on the vehicle frame, and described upper bracket is connected with described lower bracket by hydro pneumatic suspension;
As shown in Figure 4, described hydro pneumatic suspension comprises cylinder barrel, piston rod, piston, cavity is the cylinder barrel chamber between cylinder barrel and the piston base, cavity between cylinder barrel and the piston rod is annular chamber, the hollow structure of piston rod inside is rod end chamber, described cylinder barrel chamber communicates with described rod end chamber, the wall of described cylinder barrel is provided with inflation inlet and communicates with described cylinder barrel chamber, described piston rod outer end has oil-filled mouthful and communicates with described rod end chamber, the inner of described piston rod has damping hole and check valve, and described annular chamber is communicated with described rod end chamber.
Be provided with intermediate rod and postive stop baffle between the bottom in described compartment and the described vehicle frame.
The preceding bottom in described compartment and rear lower all adopt sloping formula structure, and front-row seats and back seat are installed on respectively on the inclined-plane of described sloping formula structure, and middle two row's seat back are to arranging.
Described upper bracket is fixed on the bottom, inclined-plane of described sloping formula structure, and described lower bracket adopts back pendulum droop structure.
Described intermediate rod comprises upper seat, pull bar and lower seat, and described upper seat is welded on the base plate in described compartment, and described lower seat is welded on the crossbeam of described vehicle frame, and the two ends of described pull bar are hinged with described upper seat and lower seat respectively.
Described baffle plate is welded on bottom, described compartment, and is deep into the bottom of the crossbeam of described vehicle frame.
Described baffle plate comprises front apron and back shield, and described front apron and back shield are installed in the inboard of front cross rail and the after cross member of described vehicle frame respectively.
The two ends of described hydro pneumatic suspension are hinged with described upper bracket and lower bracket respectively.
Underground transport trolley based on hydro pneumatic suspension of the present utility model in the harsh environment of down-hole, on the basis that guarantees trafficability, can improve staff's travelling comfort, increase work efficiency, increases personnel's transportation volume.
Back vehicle frame part of the present utility model mainly is made up of hydro pneumatic suspension, car body, last lower bracket and longitudinal baffle and intermediate rod, upper bracket and compartment are welded as a whole, lower bracket is stuck on the cross member of frame and is welded as a whole, hydro pneumatic suspension is installed in the middle of the lower bracket, vibration is cushioned and decay.
Consider that suspension has certain length, if the bottom, compartment is very smooth, to there be the space mounting suspension system, sloping formula structure before and after so car body adopts, to go up lower bracket be welded on domatic on, simultaneously inner seat also be installed in domatic on, so namely can effectively utilize the inner space, also a part of length of suspension can be stretched into the interior direction, increase the inner space of suspension relatively.
Be directly installed on the vehicle frame if will hang the bottom, will certainly raise the height in compartment, thereby have influence on crossing ability and the driving vision of car load.In order to reduce the height in compartment as far as possible, the utility model lower bracket adopts back pendulum droop structure, the activity space that hangs is set to nadir as far as possible, overhanging a part of distance has increased the activity space that hangs so on the one hand simultaneously, effectively reduces the relative height in compartment, and because overhanging a part of distance, make the effective length in compartment increase, and then improved the transport capacity of transport trolley, make its delivery quantity can reach 16 people.
Owing to adopted four suspensions to support the structure in compartment, and all adopted hinged mode, so there is certain swing in the compartment at vertical and horizontal.For preventing the excessive of in the vehicle movement process horizontal and vertical swing, cause the unstability in the car, the utility model vertically adopts two baffle plates, be welded on the bottom, compartment, and the position all is positioned at the cross member of frame inboard, no matter be in braking or the accelerator namely, can both play inhibit function to longitudinal oscillation.
Adopt after the hydro pneumatic suspension, must leave a certain amount of stroke space to suspension, otherwise will in vibration processes, cause the rigid impact of suspension and vehicle frame, cause the damage of car body or suspension, this will raise the whole height in compartment to a certain extent, because the height in the tunnel is certain, namely under the condition that the assurance personnel can bear, reduce its height as far as possible.Therefore, the sloping formula cargo box structure that the utility model adopts is connected support with sagging Retral swing type, has just solved this problem well.The existence on the inclined-plane of slope formula container, extended the stretched length of suspension to a certain extent, the auxiliary downward extension that sagging Retral swing type structure is arranged again, can actv. utilize the installing space between vehicle frame and the compartment, can not limit simultaneously stroke and the size of suspension cylinder, in design can not can painstakingly investigate pyknic version, reduced the rigidity of suspension to a certain extent, under its stable condition of assurance, improve its traveling comfort.
When the excitation of road surface transmission arrived vehicle frame, vehicle frame was connected with suspension by lower bracket, and after the buffering and decay through suspension, the compartment is passed in excitation.At this moment excitation can have been satisfied the requirement of human body comfort fully, but owing to employing between support and the suspension is articulated form, therefore, will inevitably in the vertical with on the side direction certain swing be arranged.
So the utility model is guaranteeing that under the comfort level situation, side direction adopts the form of intermediate rod, in the limit lateral swing, leave certain horizontal micro-amplitude of oscillation, make it possess the flexible function that stretches, avoided instantaneous stopping and the appearance of the bigger stress that causes.
Simultaneously adopt positive stop in the inboard of front and rear beam, the longitudinal oscillation in compartment is limited, guarantee when the velocity variations of front and back, can not cause that big leaning forward close layback, prevent the compartment unstability and the danger that causes.
The utility model is by the organic cooperation between each structure, both guaranteed the comfort type taken, take into account the crossing ability of vehicle simultaneously, considered the influence that inclination and trim might take place in the vehicle operating process, by position limiting structure it is limited simultaneously, realized the application of hydro-pneumatic suspension system in the middle of underground trackless transportation device.
The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
