Abstract
A lifting returning and running limiting device for a dump truck comprises a stoke contact switch, an air storage tank and an electromagnetic valve, wherein the stoke contact switch is arranged at the tank body returning standard portion of a truck body of the dump truck, an output pipeline of the air storage tank is connected with an intermediate connector which is arranged in an actuation air cylinder in a speed changing box of the dump truck and corresponds to the position of the neutral gear position of the speed changing box, and the electromagnetic valve is arranged in the output pipeline of the air storage tank and electrically connected with a stroke contact switch. By means of the working principle of the electromagnetic valve, when the contact switch is opened, the electromagnetic valve works to open an air reservoir air channel to enable the speed changing box to drive an air cylinder to work, and the speed changing box is forced at the neutral gear position to prevent automobiles from running. The lifting returning and running limiting device can change a confirm method of an existing lifting returning and running limiting device for the dump truck and guarantees accuracy and reliability of lifting returning operation of the tank body.
Description
Technical field
The utility model relates to inhibiting device, and particularly the lifting of self-unloading tipping car resets and goes the limit locking device.
Background technology
The unlimited locking device control of tumbling of tank bodies such as present similar self-unloading tipping car, tank body lifting are tumbled and are confirmed the operation overall process that resets by operating personal.
Attract the force feed tank car to belong to a kind of tank body type vehicle of tumbling.In tank body lifting and reseting procedure, lean on the elevating ram operation to accomplish, before the force feed material, must the tank body lifting be 5.3 meters apart from floor level and be in heeling condition at every turn.The material force feed finishes, and chaufeur is in case carelessness, and with the tank body original position that resets, vehicle does not sail out of station, and it is badly damaged that serious accident and vehicle that tank body and position in storehouse building collide will take place.
Summary of the invention
The purpose of the utility model is to design that the lifting of a kind of self-unloading tipping car resets and the limit locking device that goes, and changes the affirmation mode that existing self-unloading tipping car tank body lifting resets, and guarantees tank body lifting reset operation accurate reliability.
For achieving the above object, the technical scheme of the utility model is:
The lifting of self-unloading tipping car resets and the limit locking device that goes, and it comprises, the stroke contact switch is arranged at the self-unloading tipping car vehicle body upper tank body benchmark position that resets; Storage tank, its delivery conduit are connected to the meta interface of corresponding change speed gear box neutral gear position in the self-unloading tipping car speed-changing mechanism power takeoff cylinder; Electromagnetic valve is arranged in the storage tank delivery conduit, and electrically connects with the stroke contact switch.
Utilize the electromagnetic valve principle of work, when contact switch was opened, the air receiver gas circuit was opened in electromagnetic valve work, made change speed gear box carry out cylinder work, and the mandatory change speed gear box that makes is in neutral gear position, and vehicle can't go.
The beneficial effect of the utility model
The utility model has changed the affirmation mode that the lifting of existing self-unloading tipping car tank body resets, and confirms that by manual operation control change into by electricity, gas and gearing and force to confirm reseting procedure, like tank body lifting non-restoring position, vehicle can't sail out of the operation position.Tank body must reset, and vehicle just can sail out of the operation position, has guaranteed tank body lifting reset operation accurate reliability like this.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Referring to Fig. 1, the self-unloading tipping car lifting of the utility model resets and the limit locking device that goes, and it comprises, stroke contact switch 1 is arranged at the self-unloading tipping car 100 vehicle body upper tank bodies benchmark position A that resets; Storage tank 2, its delivery conduit are connected to the meta interface that self-unloading tipping car change speed gear box 200 is carried out corresponding change speed gear box neutral gear position in the cylinder 300; Electromagnetic valve 3 is arranged in storage tank 2 delivery conduits, and electrically connects with stroke contact switch 1.400 for the driving engine of self-unloading tipping car 100.
When the stroke contact switch was opened, the storage tank gas circuit was opened in electromagnetic valve energising work, made change speed gear box carry out cylinder operation, and the mandatory change speed gear box gear that makes is in neutral gear position, and the change speed gear box gear can't operational drive.
When the stroke contact switch is closed, the electromagnetic valve outage, the storage tank gas circuit is cut off, and change speed gear box is carried out the cylinder operation reduction, and the change speed gear box gear can be operated, and vehicle can be gone.
