Description

Portal crane is with hoist of weighing Technical Field The utility model relates to the technical field of gantry cranes, in particular to a weighing lifting appliance for a gantry crane. Background In the field of modern industrial production and logistics transportation, the gantry crane is used as an important hoisting device and is widely applied to links such as cargo loading, cargo transferring and the like. The device greatly improves the efficiency of cargo handling by virtue of strong lifting capacity and flexible operability, plays an indispensable role in places such as ports, wharfs, warehouses and various production workshops, and is important to accurately master the weight of the cargo in the cargo lifting process. On the one hand, accurate weight information is the basis for reasonable transportation planning and transportation safety assurance. Different types of transportation tools have strict limits on the load, if the weight of goods exceeds the bearing range, the transportation tools can be damaged, even serious traffic accidents are caused, casualties and property loss are caused, and on the other hand, in the production and manufacturing links, the accurate weighing of raw materials is beneficial to controlling the production cost and ensuring the product quality. For example, in the chemical industry, food industry, etc., the proportioning of raw materials must be strictly performed according to weight standards, and any minor weight deviation may affect the performance and quality of the product. However, when the conventional gantry crane lifts goods, an effective weighing means is often lacking, and although a part of gantry cranes are provided with simple weighing devices, most of the devices have the problems of low precision, poor stability and the like. In the lifting process, the goods can be affected by various external forces, such as the change of lifting speed, the shaking of a lifting appliance and the like, the traditional weighing device is difficult to accurately eliminate the interference factors, so that the error of the weighing result is larger, and the requirement of accurate measurement of the weight of the goods in actual production can not be met. Therefore, we propose a weighing sling for a gantry crane. Disclosure of utility model The utility model aims to provide a weighing lifting appliance for a gantry crane, which aims to solve the problems in the background technology. The movable rod is characterized by comprising a bottom plate, wherein a plurality of mounting sleeves are uniformly and fixedly arranged at the top of the bottom plate, movable rods are slidably arranged at the tops of the mounting sleeves, limiting rods are fixedly arranged at the bottoms of the movable rods, limiting plates are fixedly arranged at the bottoms of the limiting rods and positioned in the mounting sleeves, first springs are sleeved outside the limiting rods and positioned in the mounting sleeves, one ends of the first springs are fixedly connected with the mounting sleeves, the other ends of the first springs are fixedly connected with the limiting plates, top plates are fixedly arranged at the tail ends of the tops of the movable rods, a plurality of telescopic rods are uniformly and fixedly arranged at the tops of the top plates, fixing plates are fixedly arranged at the tops of telescopic arms of the telescopic rods, mounting plates are rotatably provided with mounting plates through bearings, and hanging rings are fixedly arranged at the tops of the mounting plates.
