Furthermore, the weighing sensor is packaged by a fully-sealed shell made of rolled manganese plates and is detachably mounted on the lower frame of the lifting appliance through the fully-sealed shell, and the wireless transmitting device is integrated in the fully-sealed shell.

Compared with the prior art, the utility model discloses following beneficial effect has:

(1) the utility model discloses an evenly install weighing sensor on the hoist undercarriage, absorbent material weight on the real-time detection electro-magnet, and give outside control personnel with the testing result transmission, control personnel can be fast, accurately know the weight of each position adsorbing material of hoist undercarriage, thereby whether continue adsorbing material on the electro-magnet of affirmation, ensure that material weight on each position of hoist undercarriage is in balanced state, the hoist slope of having solved because of the atress inequality appears rocks the problem even, reached balanced hoist, reduce the purpose of incident.

(2) The utility model discloses utilize the quadruple reel to realize 12 strand wire rope's connection problem to utilize 12 strand wire rope to go up to put on the shelf from all directions and go up and down simultaneously to the hoist, make the hoist put on the shelf and be connected between the dolly more firm, the equilibrium is higher, has effectively solved the problem of rocking of hoist at the lift in-process, has further improved the security of consumptive material allocation and transportation.

(3) The utility model discloses the mounted position who has changed weighing sensor moves down the hoist undercarriage from the hoist upper rack with weighing sensor for weighing sensor is closer apart from the electro-magnet, and the data of detection is closer to the weight of consumptive material self, thereby has avoided the influence of other equipment weighing sensor, has improved weighing sensor's detection accuracy greatly.

(4) The utility model discloses a totally enclosed housing symmetry sensilla seals, and air humidity, rainwater, debris wait symmetry sensilla's influence has ensured weighing sensor's life when having avoided outdoor operations.

Detailed Description

The present invention will be further described with reference to the following description and examples, which include but are not limited to the following examples.

Example 1

As shown in fig. 1, the utility model discloses a 12 rotatory hoisting mechanism of rope shaking prevention, include the hoist upper carriage and the hoist undercarriage that are connected through slewing bearing, install on this hoist upper carriage, be connected with this slewing bearing and control its pivoted motor and speed reducer to and install and be used for the pulley mechanism who is connected with the dolly at this hoist upper carriage both ends, and install be used for adsorbing the electromagnetic means of metal on the hoist undercarriage. The pulley mechanism comprises a movable pulley and a rope fixing device which are arranged at two ends of an upper frame of the lifting appliance, a four-linkage winding drum and a fixed pulley which is fixed on the four-linkage winding drum are arranged on the trolley, the movable pulley and the fixed pulley are connected through a plurality of strands of steel wire ropes, and the tail ends of the steel wire ropes are fixed on the rope fixing device; four weighing sensors electrically connected with the electromagnetic device are uniformly distributed on the lower hanger frame.

In order to improve the balance performance to the maximum extent and prevent the lifting appliance from shaking in the lifting process, the movable pulley and the fixed pulley are connected through 12 strands of steel wire ropes, and all the steel wire ropes are uniformly distributed between the upper frame of the lifting appliance and the trolley.

In order to realize real-time communication, grasp the weight of transporting the consumptive material fast, weighing sensor still is connected with outside receiving arrangement through wireless transmitting device.

In order to guarantee the service life and the detection accuracy of the weighing sensor, the weighing sensor is packaged by a full-sealed shell made of a rolled manganese plate and is detachably mounted on a lower frame of a lifting appliance through the full-sealed shell, and the wireless transmitting device is integrated in the full-sealed shell.

When the lifting appliance is in work, an operator controls the motor and the speed reducer to start in the operating room to enable the four-linked winding drum to rotate slowly, the steel wire rope moves slowly between the movable pulley and the movable pulley, the lifting appliance upper frame, the lifting appliance lower frame and the electromagnet move downwards until the lifting appliance upper frame, the lifting appliance lower frame and the electromagnet are in contact with consumable materials to be dispatched, and then the electromagnet is controlled to adsorb the consumable materials. Because install a plurality of electro-magnets on the whole hoist undercarriage, every electro-magnet all is connected with weighing sensor, consequently, when the electro-magnet adsorbs the metal consumptive material, weighing sensor will be the weight of automated inspection consumptive material in real time to data real-time transmission to the control chamber that will detect through wireless transmitting device, the weight of consumptive material is looked over directly perceivedly to the display screen in operator's accessible control chamber, and the weight at hoist undercarriage both ends is poor. But the weight is poor too much, arouses the slope easily, when rocking, the relative position of accessible control slewing bearing removal electro-magnet and consumptive material, and after the absorbent consumptive material weight in hoist undercarriage both ends is close, operator control motor antiport, under the regulation of reduction gear, wire rope is packed up gradually to the quadruple edge rolling, makes hoist upper bracket, hoist undercarriage and consumptive material rise gradually. Then, the trolley horizontally moves on the hoisting cross beam to drive the upper hanger frame, the lower hanger frame and the consumable materials to horizontally move, finally, the slewing bearing is rotated to enable the consumable materials to reach a preset position, the electromagnet is turned off, the electromagnet is separated from the consumable materials, and allocation and transportation are completed.

In the whole consumable material allocation and transportation process, the flexible operation of the mechanism can accurately and quickly complete allocation and transportation tasks, keep the balance of equipment in the allocation and transportation process and avoid large-amplitude shaking; meanwhile, the unmanned operation below is realized, the occurrence of safety accidents can be completely avoided, and the method has high practical value.

The above embodiment is only one of the preferred embodiments of the present invention, and should not be used to limit the protection scope of the present invention, but all the insubstantial changes or modifications made in the spirit and the idea of the main design of the present invention, the technical problems solved by the embodiment are still consistent with the present invention, and all should be included in the protection scope of the present invention.
