The utility model solves the problems that the most of the prior load (weighing) cells have the restriction of point stressed, and can not weigh vehicles accurately, etc., and has the advantages that the structure is simple, the use is convenient, the vehicles can be weighed accurately and rapidly, etc. The structure is as follows: the utility model comprises a hermetic shell, and a stressed slab is locked and arranged on the hermetic shell to form a hermetic cavity, four corners of the lower part of the stressed slab are respectively provided with a force sensing element, an elastic seal ring is arranged at a joint of the hermetic shell and the lower edge of the stressed slab, at least one lateral surface of the stressed slab is provided with a signal connector, and the force sensing elements are electrically connected with the signal connectors respectively.
Description
Technical field
The utility model relates to a kind of load and weighing cell, relates in particular to a kind of flat load and weighing cell that is used for the force measurement of face territory.
Background technology
Constantly perfect along with the highway system becomes more and more important to the overload of vehicle inspection work of setting out on a journey, and damages for avoiding the road overload, guarantee the safety of highway operation, often need Weighing equipment be installed, lorry weight is carried out weighing, prevent that overload from taking place in the gateway of each highway.But the existing carload metering outfit complex structure that is used for, environment for use conditional request height, measurement verification process complexity, the equipment installation project amount is big, and operation and maintenance cost height can't satisfy the requirement of the accurate weighing of load of dynamic high speed operational vehicle.
Summary of the invention
The purpose of this utility model is exactly in order to solve the used vehicle weighing apparatus structure complexity of present highway, can't carry out problems such as accurate weighing to the high-speed cruising vehicle, provide a kind of have simple in structure, easy to use, can be fast and accurately carry out dynamically or the flat load and weighing cell of advantages such as static weighing vehicle.
For achieving the above object, the utility model adopts following technical scheme:
A kind of flat load and weighing cell, it comprises capsul, fasten on the described capsul and stressed flat board is installed and is formed sealed cavity, bottom at stressed flat board respectively is implanted with a force sensing element for four jiaos, the lower edge joint of capsul and stressed flat board is provided with elastic seal ring, at least one side at stressed flat board is provided with signal connector, and each force sensing element is electrically connected with signal connector respectively.
Described force sensing element connects firmly by securing member and stressed flat board.
Described capsul is provided with the power transmission pillar for four jiaos, and stressed flat board and force sensing element are arranged on the power transmission pillar.
Described force sensing element is piezoelectric type or strain-type or piezomagnetic or optical fiber sensor.
Described signal connector is wired or wireless signal connector.
The utility model has changed existing weighing apparatus sensor has been installed in the structure of device bottom, and force sensing element is installed in the bottom of stressed flat board, the top of capsul, thus make its measurement more sensitive and accurate; Each force sensing element is connected with signal connector respectively simultaneously, and signal connector can adopt wired or wireless mode to communicate by letter with host computer, and the signal of force sensing element is sent; Be provided with elastic seal ring between seal casinghousing and stressed flat board simultaneously, guarantee the cavity sealing between capsul and stressed flat board, prevent infiltrations such as rainwater dust,, so just prevented that packoff in use is damaged because elastic seal ring is arranged on place, stressed dull and stereotyped lower edge.The utility model can be used in combination by polylith, and each signal connector is connected with data bus and gets final product, and also can carry out connection in series-parallel combination arbitrarily.
The beneficial effects of the utility model are: simple in structure, easy to use, be convenient to installation; Be convenient to the management maintenance that equipment uses the circulation process, be convenient to the metering performance calibrating of equipment; By hermetic structural design, solved corrosion protection of equipment, anti-silt ice and snow pollution problems, improve the durability of equipment and, reduce the manufacturing cost and use cost of equipment the adaptability of various environments for use; When adopting the wireless connector transmission signals, realize the wireless measurement of load data, the static and the thunder and lightning in rainy season of driving vehicle are isolated fully with indicating equipment, on electric, insulate, guarantee the electrical safety of related system with master system; The sensor of same specification has good interchangeability, does not influence the accuracy of measuring after the exchange; Exchange by sensor substitutes, and the sensor that needs annual test or maintenance is carried out in the strange land, examines and determine and need not keep in repair at the scene and carry out metering performance again; Because equipment is spliced with polylith, unit volume is dwindled, and makes the road surface stressing conditions reasonable, especially highly reduces, and can install and use on viaduct and bridge; Because the volume-diminished of equipment has reduced the consumption of the material and the energy.
