Abstract
One is weighed manual pallet truck, 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 the junction at operating cylinder and vehicle frame top, bottom and the operating cylinder of resistance strain-gauge transducer directly offset.Resistance strain-gauge transducer is arranged between oil cylinder and vehicle frame, and oil cylinder directly withstands on resistance strain-gauge transducer, so just can directly measure the power that oil cylinder pushes up.With traditional single-sensor weighing tray car adopt indirectly measure the power that oil cylinder pushes up structure compared with, it is more accurate to measure.Not only structure is simple in the present invention, cost is low, and precision is higher again.
Description
Technical field
The present invention relates to a kind of manual pallet truck, particularly one to weigh manual pallet truck.
Background technology
Along with developing rapidly of modern industry and logistic industry, manual hydraulic tray car is little, simple to operate and easy to use because of volume, and is widely used in the places such as warehouse, workshop, car harbour, is used for carrying stacking article.The all agravic sensory perceptual system of existing manual pallet truck, the weight of goods is rely on its mark completely, and when goods zero gravity mark, its actual weight is then estimated with the experience of operating personnel, make troubles to user, therefore occur that one is weighed manual pallet truck in the market.
Existing class manual pallet truck of weighing generally has two kinds: a kind of is four-sensor structure, and one is single-sensor structure.Four-sensor structure is namely each on two pallet forks of common manual tray carriage installs two resistance strain-gauge transducers, then on four sensors, a pan of a steelyard of weighing is installed, goods is positioned on pan of a steelyard, gravity is utilized to make four sensors generate signals, the signal of superposition four sensors, then utilize weighting display instrument that this weight signal is shown and namely complete whole weighing process, this structural advantages is that weighing precision is high, shortcoming is complex structure, and cost is high.Single-sensor structure and oil cylinder withstand 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, the power that oil cylinder pushes up is utilized 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 namely complete whole weighing process, this structure structure is simple, cost is low, but utilizes the method surveying frame distortion to cause measuring accuracy very low.
Summary of the invention
Technical matters to be solved by this invention provides for the above-mentioned state of the art manual pallet truck of weighing that a kind of structure is simple, cost is low, measuring accuracy is higher.
The present invention solves the problems of the technologies described above adopted technical scheme: one is weighed manual pallet truck, 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 the junction at operating cylinder and vehicle frame top, bottom and the operating cylinder of resistance strain-gauge transducer directly offset.
As improvement, be provided with a back up pad can inserted for resistance strain-gauge transducer below the top of described vehicle frame, 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, described back up pad offers corresponding screw, is connected by screw fixing; The caulking groove that can be placed in for the top of operating cylinder is provided with below the other end of described resistance strain-gauge transducer.
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 that oil cylinder pushes up.With traditional single-sensor weighing tray car adopt indirectly measure the power that oil cylinder pushes up structure compared with, it is more accurate to measure.Not only structure is simple in the present invention, cost is low, and precision is higher again.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the enlarged partial sectional view of resistance strain-gauge transducer placement location of the present invention.
Embodiment
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As shown in Figure 1, 2, one is weighed manual pallet truck, 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 the junction at operating cylinder 3 and vehicle frame 1 top, and bottom and the operating cylinder 3 of resistance strain-gauge transducer 4 directly offset; A back up pad 11 can inserted for resistance strain-gauge transducer 4 is provided with below the top of vehicle frame 1, back up pad 11 offers two screws, resistance strain-gauge transducer 4 offers corresponding through hole, by screw 6, resistance strain-gauge transducer 4 and back up pad 11 are connected and fixed, be provided with the caulking groove 41 that can be placed in for the top of operating cylinder 3 below the other end of resistance strain-gauge transducer 4, 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.When 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 namely complete whole weighing process.
