Abstract
The utility model relates to a semitrailer self-saving device, which can effectively solve the problems that after cargoes on a self-discharging transport vehicle is unloaded, the cargoes are piled up beside of the transport vehicle, and wheels are buried to lead the vehicle not to start. A self-saving oil cylinder is installed on the lower part of a vehicle chassis, and the optimal installation position of the self-saving oil cylinder is a longitudinal centerline of the rear part of the vehicle. The self-saving oil cylinder is hinged with the lower part of the vehicle chassis, with the advantages of simple operation, high work efficiency, safety, sanitation, and low cost. The utility model can also be used as a hoisting jack when the wheels are repaired or the wheels sink.
Description
Technical field
The utility model relates to a kind of can effectively the solution and is deposited in car next door after the self-discharging transporter goods unloads, and buries wheel, causes can not the start to walk superimposed trailer self-help apparatus of problem of vehicle.
Background technology
Development along with the over-the-road transportation industry, heavy goods vehicle more and more is subjected to user's favor, particularly heavy semitrailer is especially with its special advantages fast development, but because the superimposed trailer of bulk goods such as carry coal, sand, crushed stone, especially transport the side direction of this class goods and unload self-discharging semitrailer, because its carrying capacity big (generally more than 50 tons), and vehicle body is longer, after unloading, coal, sand and other items all is deposited in the car next door, very near from vehicle distances, bury wheel, cause vehicle not start to walk, want to make vehicle start, also need the manpower cleaning to bury the goods of wheel; It is reported that volume 2 people when unloading the self-unloading semi-mounted with the labor cleaning more than 50 tons approximately need 2 hours, so both wasted manpower, wasted the time again, efficient is low, and is extremely inconvenient, the domestic effective measures of not finding head it off as yet.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of superimposed trailer self-help apparatus that can be fast vehicle be separated from the goods of piling up is provided.
The purpose of this utility model is achieved in that the utility model is equipped with the oil cylinder of saving oneself in the vehicle chassis bottom, and the best position of the oil cylinder of saving oneself is vehicle rear longitudinal centerline place, and the oil cylinder of saving oneself is hinged on the vehicle chassis bottom.
The power takeoff that the oil cylinder oil circuit of saving oneself is connected by hand control valve (HCV), with hand control valve (HCV), the gear type pump that is connected with power takeoff, the Pneumatic reversal valve that is connected by check valve and gear type pump, the multiway valve that is connected with Pneumatic reversal valve, the oil cylinder of saving oneself that is connected with multiway valve, and be connected lifting cylinder oil circuit and fuel tank of multiway valve form.By the work of hand control valve (HCV) control power takeoff, power takeoff driven gear pump and by Pneumatic reversal valve to the oil circuit fuel feeding, during hydraulic oil process multiway valve, handle multiway valve, cut-out enters the oil circuit of lifting cylinder, and hydraulic oil enters the oil cylinder of saving oneself, and the oil cylinder of saving oneself is a double acting oil cylinder, control the flexible of the oil cylinder of saving oneself by multiway valve, finish and save oneself.
The utility model can be fast be separated vehicle from the goods of piling up, the whole operation process approximately need be raised the efficiency more than ten times with 5-8 minute, therefore has simple to operate, high efficiency, safety and sanitation, low, the practical advantage of cost.Also can be when wheel keeps in repair or make jack during wheel sinkage and use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the oil cylinder oil circuit scheme drawing of saving oneself of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model is equipped with the oil cylinder 8 of saving oneself in vehicle chassis 9 bottoms.The best position of oil cylinder 8 of saving oneself is vehicle rear longitudinal centerline places.The oil cylinder 8 of saving oneself is hinged on the vehicle chassis bottom.
As shown in Figure 2, the power takeoff 6 that is connected by hand control valve (HCV) 7, with hand control valve (HCV) 7 of oil cylinder 8 oil circuits of saving oneself of the present utility model, the gear type pump 4 that is connected with power takeoff 6, the Pneumatic reversal valve 2 that is connected by check valve 3 and gear type pump 4, the multiway valve 1 that is connected with Pneumatic reversal valve 2, the oil cylinder 8 of saving oneself that is connected with multiway valve 1, form be connected lifting cylinder oil circuit and fuel tank 5 of multiway valve 1.By 6 work of hand control valve (HCV) 7 control power takeoffs, power takeoff 6 driven gear pumps 4 also pass through Pneumatic reversal valve 2 to the oil circuit fuel feeding, during hydraulic oil process multiway valve 1, handle multiway valve 1, cut-out enters the oil circuit of lifting cylinder, and hydraulic oil enters the oil cylinder 8 of saving oneself, and the oil cylinder 8 of saving oneself is a double acting oil cylinder, control the flexible of the oil cylinder 8 of saving oneself by multiway valve 1, finish and save oneself.
When vehicle was not self lighting type, oil cylinder 8 oil circuits of saving oneself can directly be connect also that the oil cylinder 8 of saving oneself, Pneumatic reversal valve 2 connect hand control valve (HCV) 7, Pneumatic reversal valve 2 connects check valve 3 and gear type pump 4 and fuel tank 5 and forms by Pneumatic reversal valve 2.This oil circuit saves multiway valve 1, and oil circuit directly connects the oil cylinder 8 of saving oneself by Pneumatic reversal valve 2, by the oil cylinder work of saving oneself of hand control valve (HCV) 7 direct controls, finishes and saves oneself.
During from the power taking of tractor truck storage battery, the motor that oil cylinder 8 oil circuits of saving oneself also can be driven by storage battery, storage battery, the motor-driven gear type pump 4 that links to each other with fuel tank 5, the Pneumatic reversal valve 2 that is connected by check valve 3 and gear type pump 4, the multiway valve 1 that is connected with Pneumatic reversal valve 2, the oil cylinder 8 of saving oneself that is connected with multiway valve 1, and the multiway valve 1 lifting cylinder oil circuit that is connected form.By storage battery output 24V dc powered power is the motor of 6-8KW, by the motor-driven gear type pump 4 that links to each other with fuel tank 5.
Save oneself finish after, the oil cylinder of saving oneself can be suspended on the vehicle afterbody.
