The utility model discloses when using, hang the object on the lifting hook, when the object was hoisted, the object exerted decurrent pulling force to the bearing axle, and the tensile size equals with the gravity of object, and the bearing axle transmits the power that receives for bearing sensor, can measure the weight of handling object through weighing sensor.

Preferably, mounting plates are respectively arranged on two sides of the pulley frame, and the weighing sensor is arranged on the mounting plates.

Preferably, the connecting frame comprises two hook yoke plates parallel to each other, and a connecting plate is arranged between the two hook yoke plates.

Preferably, the weighing sensor is connected with a limiting frame used for limiting the end part of the bearing shaft. The limiting frame is used for limiting the end part of the bearing shaft, and the end part of the weighing shaft is prevented from deviating from the upper part of the weighing sensor.

Preferably, the limiting frame is U-shaped, the limiting frame is fixed on the weighing sensor through a connecting bolt, and the end part of the bearing shaft penetrates through the limiting frame.

Preferably, the pulley frame is provided with a wireless transmitting device, and the wireless transmitting device is electrically connected with the weighing sensor. The weight information of the objects obtained by the weighing sensor is transmitted to the display terminal through the wireless transmission device, the wireless receiving module and the processing module are arranged in the display terminal, the processing module converts the weight information obtained by the weighing sensor into numerical values after processing, and the numerical values are displayed through the display terminal, so that an operator can conveniently know the weight of the lifted objects.

The utility model has the advantages that: the utility model discloses when using, hang the object on the lifting hook, when the object was hoisted, the object exerted decurrent pulling force to the bearing axle, and the tensile size equals with the gravity of object, and the bearing axle transmits the power that receives for bearing sensor, can measure the weight of handling object through weighing sensor.

Detailed Description

The invention will be further described with reference to the following detailed description and accompanying drawings.

Example 1:

as shown in fig. 1 and 2, a crane hook set with weighing function includes a pulley yoke 3 and a bearing shaft 5. A pulley shaft 2 is arranged on the pulley yoke 3, and a pulley 1 is rotatably connected on the pulley shaft 2. Mounting plates 7 are arranged on two sides of the pulley frame, and weighing sensors 6 are arranged on the mounting plates 7. The load cell 6 is prior art. The specific structure of the weighing sensor 6 can be found in the invention patent with the publication number CN 101017108A. The two ends of the bearing shaft 5 are respectively abutted against the upper ends of the weighing sensors 6. The pulley yoke 3 is provided with a through hole through which the bearing shaft 5 can pass. The bearing shaft 5 is positioned below the pulley shaft 2. The bearing shaft 5 is connected with a connecting frame 8.
