Abstract
The utility model provides a pair of truck scale weighing platform level alarm device, include: a base with an opening at the upper end; the laser emitter is arranged on the left side of the base and emits laser perpendicular to the bottom edge of the base during working; the right side is provided with a laser sensor which receives laser signals during working; a power supply and a control center are arranged in the base; a plane mirror is arranged on a base which is vertical to the lower end of the upper end opening and plays a role of reflecting laser. The utility model discloses whether the detectable weighing platform is in the horizontality, the installation is at the inside top of truck scale weighing platform.
Description
Technical Field
The utility model relates to a technical field that weighs specifically is a truck scale weighing platform horizontally alarm device.
Background
With the ever-increasing transportation industry in China, the highway toll collection work is also very important. The road weight charging is mainly based on the actual weight of the truck, so the truck scale must accurately weigh the truck. However, when weighing is actually performed, the weighing is often affected by various complex factors, so that a large error exists between the weighing value and the actual value, which results in measurement disputes. Therefore, a device for detecting whether the weighing platform is horizontal and alarming is needed.
Disclosure of Invention
An object of the utility model is to provide a platform level alarm device judges whether the platform is horizontal through the time of whether laser sensor received signal and received signal.
In order to achieve the above object, the present invention provides the following solutions: a weighing platform level alarm device comprises a base with an opening at the upper end, a laser emitter and a laser sensor; the laser emitter emits laser to enter the reflecting surface of the reflector; a mirror reflecting the laser beam; the laser sensor receives the reflected laser signal, and if the reflected signal is not received, the device gives an alarm; the weighing platform level alarm device is characterized in that: the base with the upper end opening is centrosymmetric; the laser emitter and the sensor are centrosymmetric; the reflector is positioned on the central point and is arranged on a horizontal table of the gyroscope structure.
As an improvement of the above technology, the base with the upper end opened is arranged at the upper end of the weighing platform.
As an improvement of the technology, the laser emitter and the laser sensor are arranged in the clamping groove with an opening at the upper end.
As an improvement of the above technique, the control is provided inside the upper end opening.
Compared with the prior art, the beneficial effects of the utility model are as follows:
the utility model discloses a laser emitter and laser sensor cooperation work judge whether the weighing platform is level. The process is convenient, the working efficiency is high, and the practical value is high.
Drawings
Fig. 1 is the structure schematic diagram of the weighing platform level alarm device of the utility model.
In the figure: a base with an opening at the upper end 1, a laser emitter 2, a reflector 3 and a laser sensor 4.
Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are only some embodiments, but not all embodiments, of the present invention. Based on the utility model discloses well ground embodiment, this neighborhood ordinary skilled person does not make all other embodiments of the ground that obtains under the creative ground of working, all belongs to the utility model discloses the scope of protection.
Please refer to fig. 1, the present invention provides a solution: a weighing platform level alarm device comprises a base (1) with an opening at the upper end, a laser emitter (2), a reflector (3) and a laser sensor (4). The weighing platform alarm device is arranged at the top of the weighing platform, and the laser emitter (2) is arranged at the left end of the base (1) with an opening at the upper end; the laser sensor (4) is arranged at the right end of the base (1) with an opening at the upper end.
Further improved, as shown in fig. 1: the laser gyroscope is characterized in that the reflective mirror (3) is positioned on a horizontal table of a gyroscope structure, the reflective mirror (3) is always kept in a horizontal state, when the device is inclined along with a weighing platform, the incident angle of laser emitted by the laser emitter (2) to the reflective mirror is changed, and the reflected laser cannot be received by the laser sensor (4). Thereby judging that the weighing platform is inclined.
The vehicle weighing device is further improved in that when a vehicle passes through the weighing platform, the weighing platform deforms, so that the device gives an alarm, when the vehicle passes through the weighing platform, the weighing platform is recovered, the alarm of the device is relieved, if the weighing platform inclines, the alarm cannot be relieved, and therefore the alarm time of the device is used for determining whether the weighing platform inclines or not.
The product that this scheme protected is more in the car weighing measurement field application, mainly used weighing platform's inclination's detection to improve the measurement accuracy of car weight, accord with social demand, suitable batch production and use widely.
Claims (3)
1. The utility model provides a motor truck scale weighing platform level alarm device which characterized in that includes: the upper end of the base is provided with an opening (1) for installing a laser transmitter (2) and a laser sensor (4); mirror (3): the gyroscope structure is arranged on the base and used for receiving the laser beam and reflecting the laser beam; laser emitter (2): emitting laser to the reflecting surface of the reflector; laser sensor (4): and receiving the reflected laser signal, wherein if the laser sensor receives the signal, the device is horizontal, and otherwise, the device is inclined.
2. The apparatus of claim 1, wherein: the base (1) with the upper end opening is symmetrical about the center, and the laser emitter (2) and the laser sensor (4) are symmetrical about the center.
3. The apparatus of claim 1, wherein: the reflecting mirror is installed on the horizontal plane of the gyroscope and always keeps a horizontal state.
