In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.
The embodiments in the present specification are described in a progressive manner, and the same and similar parts among the embodiments are referred to each other, and each embodiment focuses on the differences from the other embodiments.
Furthermore, the terms "proximate," "distal," "front," "back," "A," "B," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicit to a location of an indicated technical feature.
In the present invention, unless otherwise expressly stated or limited, the terms "provided", "disposed", "communicated", "connected", and the like are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally formed; may be a mechanical connection; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
As shown in fig. 1 to 3, a vehicle positioning apparatus for an unloader, includes:
the wheel stopper 1 is arranged on the unloader platform 9 and used for limiting the wheels 12;
The distance between the centers of the two locators and the wheel stopper 1 is larger than or equal to the radius of the wheel 12. The larger value is slightly larger than the larger value and is generally within 20mm, so that the wheel 12 can be just completely blocked after the wheel stopper 1 is lifted after the wheel 12 is positioned.
The positioner is in a trapezoidal shape. Simple structure can pass through the bolt during installation with the locator fastening on the car unloader platform. The surface of the locator can be added with anti-slip rubber. And is convenient to install on the unloader platform 9.
The two inclined surfaces 203 are arranged in a V shape, and the inclination angle of the inclined surfaces is 30-60 degrees. The resistance is not easy to be overlarge while the limiting is convenient.
The inclined surface 203 is inclined at an angle of 45 °.
Two the locator is close to what keep off wheel ware 1 is locator A201, keeps away from what keep off wheel ware 1 is locator B202, locator A201 both sides are equipped with and are used for detecting the correlation laser sensor A3 of wheel 12, keep off wheel ware 1 with correlation laser sensor A3 is connected with controller 4. The laser sensor a3 can detect the position of the wheel 12 to remind the driver of the position of the wheel 12 to make a neutral braking operation in time, so that the wheel is finally stopped at a set position under the gravity of the vehicle.
The positioner A201 is provided with a through hole 204 for the catch wheel 1 to pass through.
The wheel stopper 1 comprises a wheel stopping hydraulic cylinder 101 vertically arranged on the unloader platform 9, and a wheel stopping plate 102 is arranged on the wheel stopping hydraulic cylinder 101.
The controller 4 is connected with a correlation laser sensor B5 for detecting the front end position of the vehicle 11, and the controller 4 is also connected with a display 6 and a voice alarm 7 respectively. Visual reminding and voice reminding are realized.
The controller 4 is a PLC controller, and can specifically adopt an S7-200 PLC produced by Siemens.
The correlation laser sensor a3 and the correlation laser sensor B5 may be model E3Z-LT81 manufactured by ohron.
The application vehicle positioner's working process:
at present, two main types of running of a vehicle 11 are performed when the unloader 8 unloads, wherein one type is that the vehicle 11 is directly backed into the unloader 5, and then wheels 12 are blocked by a wheel stopper 1 for unloading; and the other is that the vehicle 11 is firstly driven into the unloader 5, then is backed to the wheel stopper 1, and the wheel stopper 1 is used for stopping the wheels 12 for unloading. Because the two vehicles need to be backed to reach the wheel stopper 1 during running, the vehicle positioning device can realize positioning.
When the vehicle 11 is backed, a display 6 convenient for viewing prompt information is arranged on one side in front of the driver, when the wheel 12 of the vehicle 11 reaches the locator B202, a certain resistance exists, the driver can generally feel the resistance (no feeling or no matter what is needed, two inclined planes 203 are arranged behind the locator B to locate the wheel 12 and remind the detection signal of the laser sensor A3), at the moment, the driver is required to supply oil to enable the vehicle 11 to run on the locator B202, then the wheel 12 runs a small section on the locator B and enters the inclined planes 203, at the moment, the laser sensors A3 on the two sides of the inclined planes detect the signal, the display 6 and the voice alarm 7 respectively remind the driver of the need of decelerating and engaging the neutral gear, the vehicle 11 slowly slides down until the vehicle is not moved after the brake of the vehicle is completely released after engaging the neutral gear, at the moment, the wheel is between the two inclined planes (because the two inclined planes 203 block the wheel 12, the vehicle 11 can only stay between the two inclined surfaces 203 under its own weight), then the wheel chock 1 is lifted to completely block the wheels 12, and then the unloader platform 9 is lifted and unloaded by the unloader hydraulic cylinder 10 at the unloader 8. The vehicle positioning device can provide relatively accurate positioning information for a driver and make the vehicle 11 finally stop at a set position by means of the gravity of the vehicle by utilizing the two inclined surfaces 203, so that the positioning precision is further improved.
The above-mentioned specific embodiments can not be regarded as the restriction to the scope of protection of the utility model, to technical personnel in this technical field, it is right the utility model discloses any replacement improvement or transform that embodiment made all fall within the scope of protection of the utility model.
The parts of the present invention not described in detail are the known techniques of those skilled in the art.
