Abstract
The utility model provides an adjustable suspension device for road-surface accelerated loading experimental equipment, which belongs to the field of experimental equipment. The utility model is characterized in that when the road-surface accelerated loading experimental equipment works, an adjustable suspension is fixed at the rear part of a vehicle frame in order to prevent the adjustable suspension from interfering with running cars to satisfy the need of short distance moving; when the road-surface accelerated loading experimental equipment needs long distance transition transportation, the adjustable suspension is fixed at the middle of the vehicle frame. By using the adjustable suspension device, the shaft distance of the whole road-surface accelerated loading experimental equipment can be conveniently adjusted to satisfy the needs of the short distance moving or long distance transition transportation, so the maneuverability, the trafficability characteristic and the safety are improved.
Description
(1) technical field
The utility model relates to a kind of adjustable draft hitch that is used for road surface accelerating and loading experimental equipment, belongs to the experimental facilities field.
(2) background technology
Road surface accelerating and loading experimental equipment is the specialized equipment of test ground surface material and structure.The draft hitch position of existing road surface accelerating and loading experimental equipment is fixed, and causes the wheelbase of road surface accelerating and loading experimental equipment long, and turning diameter is too big, and the transition transportation is limited, and its maneuverability, trafficability characteristic and security are difficult to guarantee.
(3) summary of the invention
Technical assignment of the present utility model is the deficiency at existing road surface accelerating and loading experimental equipment, provide a kind of and both satisfied the road surface accelerating and loading experimental equipment work and needs are moved in short distance, can satisfy its long distance transition traffic requirements again, and regulate adjustable draft hitch easy for installation, improve the reliability of road surface accelerating and loading experimental equipment transition transportation and work.
The technical scheme that its technical matters that solves the utility model adopts is: suspension crossbeam and suspension longeron are formed framed structure, the suspension longeron is welding back-covered steel plate spring assembly down, the suspension longeron is connected with the vehicle frame of experimental facilities by coupling bolt, between the suspension crossbeam air drum is installed.
Above-mentioned adjustable draft hitch, be fixed on by coupling bolt on the vehicle frame of experimental facilities, when the road surface accelerating and loading experimental equipment work, adjustable suspension is fixed on the vehicle frame rear portion, when the long distance transition of road surface accelerating and loading experimental equipment transportation, adjustable suspension is fixed on the vehicle frame middle part.
A kind of adjustable draft hitch that is used for road surface accelerating and loading experimental equipment of the present utility model compared with prior art, the beneficial effect that is produced is: adopt this draft hitch, can adjust the wheelbase of whole road surface accelerating and loading experimental equipment easily, satisfy short distance transportation or long distance transition traffic requirements, improved its maneuverability, trafficability characteristic and security.
(4) description of drawings
Fig. 1 is an adjustable draft hitch front view of the present utility model.
Fig. 2 is an adjustable draft hitch installation diagram of the present utility model.
Among the figure, 1, the suspension crossbeam, 2, the suspension longeron, 3, the back-covered steel plate spring assembly, 4, coupling bolt, 5, air drum, 6, vehicle frame.
(5) embodiment
Explain below in conjunction with Fig. 1, Fig. 2 a kind of adjustable draft hitch that is used for road surface accelerating and loading experimental equipment of the present utility model being done.
As shown in Figure 1 and Figure 2, a kind of its structure of adjustable suspender that is used for road surface accelerating and loading experimental equipment of the present utility model comprises---1, the suspension crossbeam, 2, the suspension longeron, 3, back-covered steel plate spring assembly, 4, coupling bolt, 5, air drum, 6, vehicle frame.
The above-mentioned adjustable suspender that is used for road surface accelerating and loading experimental equipment, suspension crossbeam 1 and suspension longeron 2 are formed framed structure, 2 times welding of suspension longeron back-covered steel plate spring assembly 3, suspension longeron 2 is connected with the vehicle frame 6 of experimental facilities by coupling bolt 4, and air drum 5 is installed between the suspension crossbeam 1.
Above-mentioned adjustable draft hitch, be fixed on by coupling bolt 4 on the vehicle frame 6 of experimental facilities, when the road surface accelerating and loading experimental equipment work, adjustable suspension is fixed on vehicle frame 6 rear portions, when the long distance transition of road surface accelerating and loading experimental equipment transportation, adjustable suspension is fixed on vehicle frame 6 middle parts.
Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.
