Description
Technical field
The utility model relates to a kind of weighing apparatus, especially relates to a kind of weighing device of weighing when being applicable to liftings such as container.
Background technology
At present; The container at a large amount of harbours is weighed and other bulk supply tariff is weighed normally utilizes electronic vehicle weighing apparatus to accomplish, and this type of weighing apparatus generally comprises a weighing platform, is located at gravity sensor and corresponding operation, control circuit and display device weighing platform under, exists drawback such as have high input, expense height, workload are big; And; When lifting container or goods, can not carry out online weighing, the efficient of therefore weighing is low.In addition, owing to be not directly container or goods to be weighed, therefore, its error of weighing is bigger, and precision is not high enough.
The utility model content
The utility model is in order to solve the existing in prior technology problem that efficient is low, error is big and expense is high of weighing, and a kind of weighing system of weighing when being applicable to container and other items lifting is provided, to realize high precision, online weighing fast cheaply.
To achieve these goals; The utility model adopts following technical scheme: a kind of suspension type weighing device; Comprise gravity sensor, arithmetic control circuit and display device; Also comprise the suspension hook that is used for Under-Slung Loads and be used for connecting shackle and the web member of boom hoisting; The upper end of said suspension hook and the lower end of web member are respectively equipped with axis hole, and said gravity sensor is a resistance strain type sensor, it comprise a sleeve-like shell, elastic body in the enclosure, the signal output part that sticks on the resistance strain gage on the elastic body and be located at shell one end are set; Gravity sensor is arranged in the axis hole of suspension hook and web member with connecting shackle and web member, is provided with the sheath of hard on the periphery of gravity sensor shell with the axis hole joint place.The utility model adopts is the suspension type mode of weighing; Suspension hook is installed on crane, the overhead travelling crane, the online weighing in the time of can realizing the goods lifting, and resistance strain type sensor has the precision height; Measurement range is wide, the life-span is long, simple in structure, the advantage that can under mal-condition, work; Therefore, make whole weighing device be easy to realize high precision, low cost, and rugged surroundings and weather during open work such as suitable harbour.Particularly, shell need have certain elastic deformation, thereby makes its inner resistance strain gage can be along with elastic body deformation together; And then cause the variation of resistance value and export corresponding electric signal that therefore, the material of shell can not be really up to the mark; The utility model is provided with the hard sheath with the axis hole joint place on the periphery of shell, but protecting sheathing avoids wearing and tearing, prolongs its serviceable life; Simultaneously, can keep shell to have certain elastic deformation.
As preferably, said web member is inverted U-shaped, and said resistance strain gage is made up of first resistance strain gage and second resistance strain gage, and first resistance strain gage and second resistance strain gage are arranged on the elastic body both sides symmetrically.Obtain mean value after can the data of weighing of two resistance strain gages output signals being calculated, thereby help eliminating the weighting error that the error because of resistance strain gage causes, with further raising weighing precision.
As preferably; Said gravity sensor is provided with the flat breach of anti-rotation on the periphery away from signal output part one side; Thereby can prevent the rotation of resistance strain type sensor to make resistance strain gage remain identical position and state, thereby weighing precision is consistent.
Therefore, the weighing precision of the utility model is high, low cost of manufacture, and can realize quick online weighing.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further description.
In Fig. 1, embodiment shown in Figure 2; A kind of suspension type weighing device; It comprises the suspension hook 1 that is used for Under-Slung Loads, the web member 3 that is used for connecting shackle and boom hoisting, gravity sensor 2 and corresponding operation control circuit and display device (not shown); Said web member is inverted U-shaped, and suspension hook then is J-shaped, and two lower ends of the upper end of suspension hook and web member opening are respectively equipped with axis hole 4.As shown in Figure 3; What gravity sensor 2 adopted is resistance strain type sensor; Resistance strain type sensor integral body is the bearing pin shape; It comprises a sleeve-like shell 21, in the enclosure elastic body (not shown) be set, stick on the resistance strain gage on the elastic body, resistance strain type sensor shell one end is provided with signal output part 22 being used to connect corresponding operation control circuit and display device, it is interior with connecting shackle and web member that resistance strain type sensor is arranged in the axis hole of suspension hook and web member; Suspension hook then is positioned at the opening of inverted U-shaped web member; And on the periphery of shell and axis hole joint place is provided with the sheath 5 of three hard, and sheath its surface after bakingout process has high hardness, thereby makes resistance strain type sensor have good abrasion resistance.In order to improve measuring accuracy, resistance strain gage is made up of first resistance strain gage 6 and second resistance strain gage 7, and first resistance strain gage and second resistance strain gage are arranged on the position, space of the suspension hook and the web member of elastic body both sides symmetrically.Further, on periphery, the flat breach 8 of anti-rotation is set away from the sheath of signal output part, corresponding ground, it is protruding 9 to be provided with anti-rotation in the axis hole of web member one side, thereby can avoid the rotation of gravity sensor, plays the effect of a location.
The utility model can be used with lifting appliances such as crane, overhead travelling crane; It is replaced the suspension hook of original lifting appliance; When slinging goods, the weight of goods is delivered on the gravity sensor through suspension hook, and first resistance strain gage in the gravity sensor and second resistance strain gage are exported signal because of receiving stress-strain; And pass through to export an average weight value on display device behind the arithmetic control circuit, thereby can weigh by many rapidly and accurately goods.
