Abstract
A weighing manual pallet truck comprises a truck frame, a truck rod, a working oil cylinder and a resistance strain slice type sensor and is characterized in that the resistance strain slice type sensor is arranged between the working oil cylinder and the connection portion at the top of the truck frame, and the bottom of the resistance strain slice type sensor directly abuts against the working oil cylinder. The resistance strain slice type sensor is arranged between the oil cylinder and the truck frame, and the oil cylinder directly abuts against the resistance strain slice type sensor, so that the jacking force of the oil cylinder can be directly measured. Compared with a traditional single-sensor weighing pallet truck which adopts a structure indirectly measuring the jacking force of the oil cylinder, the pallet truck is accurate in measurement. The weighing manual pallet truck is simple in structure, low in cost and high in accuracy.
Description
Technical field
The present invention relates to a kind of manual pallet car, the particularly one manual pallet car of weighing.
Background technology
Along with developing rapidly of modern industry and logistic industry, manual hydraulic tray car, because volume is little, simple to operate and easy to use, and is widely used in the places such as warehouse, workshop, car harbour, is used for carrying stacking article.All agravic sensory perceptual systems of existing manual pallet car, the weight of goods is to rely on its mark completely, and in the time of goods zero gravity mark, its actual weight is estimated with operating personnel's experience, make troubles to user, therefore occur in the market the one manual pallet car of weighing.
The existing class manual pallet car of weighing generally has two kinds: a kind of is four-sensor structure, and one is single-sensor structure.Four-sensor structure i.e. two resistance strain-gauge transducers of each installation on two pallet forks of common manual tray carriage, then the pan of a steelyard of weighing is installed on four sensors, goods is positioned on pan of a steelyard, utilize gravity to make four sensors produce signal, the signal of four sensors of stack, then utilizes weighting display instrument that this weight signal is shown and completes whole weighing process, and this structural advantages is that weighing precision is high, shortcoming is complex structure, and cost is high.Single-sensor structure is that oil cylinder withstands on manual pallet vehicle carriage top, then at manual pallet vehicle carriage top, one resistance strain-gauge transducer is installed, goods is directly positioned on tray carriage vehicle frame, utilize the power of pushing up on oil cylinder to make vehicle frame top produce distortion, resistance strain-gauge transducer records this distortion, produce signal, then utilize weighting display instrument that this weight signal is shown and completes whole weighing process, this structure is simple in structure, cost is low, but utilizes the method for measuring car frame distortion to cause measuring accuracy very low.
Summary of the invention
Technical matters to be solved by this invention is that a kind of simple in structure, cost is low, measuring accuracy is higher manual pallet car of weighing is provided for the above-mentioned state of the art.
The present invention solves the problems of the technologies described above adopted technical scheme: the one manual pallet car of weighing, comprise vehicle frame, car bar, operating cylinder and resistance strain-gauge transducer, it is characterized in that: described resistance strain-gauge transducer is arranged between operating cylinder and the junction at vehicle frame top, and bottom and the operating cylinder of resistance strain-gauge transducer directly offset.
As improvement, the below, top of described vehicle frame is provided with the back up pad that can insert for resistance strain-gauge transducer, and one end of described resistance strain-gauge transducer is placed in back up pad, and the top of the other end and operating cylinder offsets.
Finally, one end of described resistance strain-gauge transducer offers at least one through hole, offers corresponding screw in described back up pad, is connected by screw fixing; The other end below of described resistance strain-gauge transducer is provided with the caulking groove that can be placed in for the top of operating cylinder.
Compared with prior art, the invention has the advantages that: resistance strain-gauge transducer is arranged between oil cylinder and vehicle frame, oil cylinder directly withstands on resistance strain-gauge transducer, so just can directly measure the power of pushing up on oil cylinder.Compared with adopting with traditional single-sensor weighing tray car the structure of indirectly measuring the power of pushing up on oil cylinder, it is more accurate to measure.The present invention not only simple in structure, cost is low, and precision is higher again.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the local amplification view of resistance strain-gauge transducer placement location of the present invention.
Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the present invention.
As shown in Figure 1, 2, the one manual pallet car of weighing, comprise the parts such as vehicle frame 1, car bar 2, operating cylinder 3 and resistance strain-gauge transducer 4, resistance strain-gauge transducer 4 is arranged between operating cylinder 3 and the junction at vehicle frame 1 top, and the bottom of resistance strain-gauge transducer 4 and operating cylinder 3 directly offset; The below, top of vehicle frame 1 is provided with the back up pad 11 that can insert for resistance strain-gauge transducer 4, in back up pad 11, offer two screws, on resistance strain-gauge transducer 4, offer corresponding through hole, by screw 6, resistance strain-gauge transducer 4 and back up pad 11 are connected and fixed, the other end below of resistance strain-gauge transducer 4 is provided with the caulking groove 41 that can be placed in for the top of operating cylinder 3, and the top of operating cylinder 3 is embedded in the caulking groove of resistance strain-gauge transducer 4 and directly offsets with resistance strain-gauge transducer 4.
Like this, operating cylinder 3 on resistance strain-gauge transducer 4, can directly utilize resistance strain-gauge transducer 4 to measure the acting force of operating cylinder 3 with regard to immediate roof.While weighing, utilize the power on top on operating cylinder 3 to make vehicle frame 1 top produce distortion, resistance strain-gauge transducer 4 records this distortion, produces signal, then utilizes weighting display instrument that this weight signal is shown and completes whole weighing process.
Claims (3)
1. the manual pallet car of weighing, comprise vehicle frame, car bar, operating cylinder and resistance strain-gauge transducer, it is characterized in that: described resistance strain-gauge transducer is arranged between operating cylinder and the junction at vehicle frame top, and bottom and the operating cylinder of resistance strain-gauge transducer directly offset.
2. the manual pallet car of weighing according to claim 1, the below, top that it is characterized in that described vehicle frame is provided with the back up pad that can insert for resistance strain-gauge transducer, one end of described resistance strain-gauge transducer is placed in back up pad, and the top of the other end and operating cylinder offsets.
