Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a mechanical rotary lifting and adjusting device. Background Art

[0002] When transporting bulk goods on the shore to a cargo ship, a belt conveyor is mostly used. One end of the conveyor is fixedly connected to the shore, and the other end is fixedly connected to the cargo ship. Since the rise and fall of the tide will cause the height of the cargo ship to change, which will cause the floating, falling and drifting of the conveyor belt of the belt conveyor, affecting the safe operation of the conveyor. Therefore, we make improvements on this and propose a mechanical lifting and adjusting device for the conveyor.

[0003] A mechanical lifting and adjusting device for a conveyor recorded in a patent document with a patent publication number of CN211593932U includes a bottom plate. On both sides above the bottom plate, a first hydraulic cylinder and a second hydraulic cylinder are provided. A connecting rod is connected between the first hydraulic cylinder and the second hydraulic cylinder. The number of connecting rods is three. Two of them are cross-connected to fixedly connect the first hydraulic cylinder and the second hydraulic cylinder to the bottom plate. The remaining one connecting rod is horizontally arranged to fixedly connect the first hydraulic cylinder and the second hydraulic cylinder. The output ends of the first hydraulic cylinder and the second hydraulic cylinder are both connected with piston rods. The top of the piston rod is connected with a placing plate. A through groove is provided on the upper part of the placing plate, and a right clamping plate and a left clamping plate are respectively provided on the left and right sides of the through groove. A lead screw passes through the middle of the right clamping plate and the left clamping plate. This kind of mechanical lifting and adjusting device for a conveyor can meet the height adjustment of the conveyor belt and has high practical value. However, the angle of this device is fixed and cannot be rotated. When rotation adjustment is required, the entire device needs to be rotated, and the use limitation is relatively large. Moreover, when adjusting the height at both ends of this device, the lifting is carried out by the cooperation of the hydraulic cylinders on both sides, and the adjustment effect is poor and the accuracy is low.

[0004] Based on this, a mechanical rotary lifting and adjusting device is now provided, which can eliminate the disadvantages of the existing device. Summary of the Utility Model
