The specific embodiment
Be elaborated below in conjunction with the specific embodiment of accompanying drawing to the utility model.Should be understood that the specific embodiment described herein only is used for explanation and explains the utility model, is not limited to the utility model.
In the utility model, under the situation of not doing opposite explanation, the noun of locality of use typically refers to the direction of work bucket under the situation of normal operation of the utility model, the just above and below shown in the accompanying drawing like " upper and lower ".
The utility model provides a kind of work bucket, and this work bucket comprises that the bucket case 1 and the case 1 that will struggle against are installed to the link span 2 on the aerial platform, wherein, link together through the pressure sensor 3 that is electrically connected with controller between said bucket case 1 and the link span 2.
The work bucket of the utility model comprises bucket case 1 and link span 2, and bucket case 1 is installed on the aerial platform through link span 2.Different with the weighting apparatus of existing work bucket, be connected through pressure sensor 3 between bucket case 1 of the utility model and the link span 2, that is to say that the junction between bucket case 1 and link span 2 all is provided with pressure sensor 3.Because the total weight of bucket case 1 and in-to-in load thereof is all supported by link span 2, therefore be installed in the total weight that the pressure sensor 3 that struggles against between case 1 and the link span 2 is accepted bucket case 1 and load thereof.
Need to prove; This link span 2 can be for one or more; These one or more link spans 2 can be as required be provided with together support bucket case 1 with mode arbitrarily; And can be provided with one or more pressure sensors 3 on each link span 2, a plurality of pressure sensors 3 that are arranged on the same link span 2 also can be provided with arbitrarily to be used for carrying the total weight of bucket case 1 and load thereof.And; When link span 2 when being a plurality of; Not only these a plurality of link spans 2 can at random be provided with; For example the bigger position of load is provided with the stability that more link span 2 supports with raising in bucket case 1, and the form that is provided with of the pressure sensor 3 on each link span 2 can be identical with quantity, also can have nothing in common with each other.In a word, the quantity of link span 2 and/or pressure sensor 3 can be according to actual needs with the form that is provided with and be provided with arbitrarily.In embodiment illustrated in figures 1 and 2; Only schematically show the embodiment that a pressure sensor 3 is set on the link span 2; To those skilled in the art, be easy to expect how a plurality of link spans 2 and/or a plurality of pressure sensor 3 are provided with, the respective drawings of therefore no longer giving an example.
That is to say, if this work bucket includes only a link span 2, and only be provided with a pressure sensor 3 on this link span 2, the reading of this pressure sensor 3 is exactly the total weight of bucket case 1 and load thereof so; If this work bucket comprises a link span 2 and this link span 2 and is provided with a plurality of pressure sensors 3; Perhaps this work bucket comprises a plurality of link spans 2; Each link span 2 is provided with one or more pressure sensors 3, and the reading sum of so all pressure sensors 3 is exactly the total weight of bucket case 1 and load thereof.
Pressure sensor 3 detected pressure signals are sent to controller; If pressure sensor 3 is a plurality of; The force value addition that controller will these a plurality of pressure sensors 3 be detected promptly obtain the struggling against weight sum of case and load, the weight that only need therefrom deduct bucket case 1 self can obtain the weight of load.
Controller is electrically connected to accept the measurement signal of pressure sensor 3 with pressure sensor 3.For digital pressure sensor 3, can directly be connected with controller, if the measurement signal of pressure sensor 3 is an analog quantity, then need be connected and carries out being sent to controller again after the A/D conversion with A/D converter.
Preferably, said pressure sensor 3 removably is connected with said bucket case 1 and/or said link span 2.Perhaps, preferably, said pressure sensor is welded on said bucket case 1 and/or the said link span 2.
Because the installation site of pressure sensor 3 is more special, therefore, for the ease of dismounting and maintenance, pressure sensor removably is connected with bucket case 1 and/or link span 2 usually.Certainly, in order to fix bucket case 1 more firmly, the mode that also can handle captive joints such as welding is fixed to pressure sensor 3 on bucket case and/or the link span 2.In addition, also can make pressure sensor 3 removably be connected to bucket case 1 and link span 2 the two one of, and be fixedly attached on another.
Preferably, the mounting structure that has said pressure sensor 3 on said bucket case 1 and/or the said link span 2.According to the different structure and the functional character of pressure sensor 3, the attachment face of this pressure sensor can be in the top and bottom of sensor, also can be in two sides, and its mounting means can be a bolted connection, also can be captive joints such as welding.But the utility model is preferably through mounting structure and removably connects; The installation of pressure sensor 3 is the technology that is in daily use to those skilled in the art; And correspondingly different according to dissimilar pressure sensor 3, so the utility model does not limit this mounting structure.
Preferably, said mounting structure comprises L shaped 4, and this face of L shaped 4 is fixed on said bucket case 1 or the said link span 2, and another face is connected with said pressure sensor 3.
As shown in Figure 1, this mounting structure can be L shaped 4, forms by each other vertically being connected to two L shaped faces for this L shaped 4, and one of them face is fixed on said bucket case 1 or the said link span 2, and another face is connected with said pressure sensor 3.And; Can connect through floor between two faces of L shaped 4; To form structure shown in Figure 1; This L shaped 4 side view shows at Fig. 1 with floor is a right-angled triangle, and this L shaped 4 is connected with pressure sensor 3 through bolt, but also can be provided with the floor that plays additional strengthening intensity.
Preferably, said pressure sensor 3 is a LOAD CELLS.LOAD CELLS is the sensor that the testee quality conversion is become electric signal, and LOAD CELLS is usually to quality, and division also has polytype according to principle of measurement.In practical application, can select accordingly according to range for measuring, precision and installation environment etc.
Preferably, said controller is connected with read out instrument and/or warning device.
This controller receives after the measurement signal from pressure sensor 3, needs this gravimetric value is shown for the operating personal reference, when the weight of load surpasses nominal payload, also need report to the police to remind operating personal to take appropriate measures.
The utility model also provides a kind of aerial platform, and this aerial platform has the work bucket, and wherein, said work bucket is according to the described work bucket of the utility model.Like this, the aerial platform that the utility model provided can obtain the weight of load in the work bucket more exactly, causes danger avoiding.
More than combine accompanying drawing to describe the preferred implementation of the utility model in detail; But; The utility model is not limited to the detail in the above-mentioned embodiment; In the technical conceive scope of the utility model, can carry out multiple simple variant to the technical scheme of the utility model, these simple variant all belong to the protection domain of the utility model.
Need to prove in addition; Each concrete technical characterictic described in the above-mentioned specific embodiment under reconcilable situation, can make up through any suitable manner; For fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible array modes.
In addition, also can carry out combination in any between the various embodiment of the utility model, as long as its thought without prejudice to the utility model, it should be regarded as content disclosed in the utility model equally.
