Technical Field

[0001] The invention relates to the technical field of port mechanical equipment hoisting, in particular to a self-stabilizing mechanical equipment hoisting and installation mechanism. Background Art

[0002] Port equipment lifting refers to the process of installing, moving or unloading various equipment and cargo in the port through lifting machinery. Existing lifting equipment mainly includes cranes, gantry cranes, bridge cranes, etc. The lifting equipment is calculated, selected and installed according to factors such as the size and weight of the container, lifting distance, and environment, and the lifting operation is carried out in accordance with safety operating procedures. The invention with the announcement number CN117088236B discloses a steel structure hoisting device, in which the limit unit is installed in the middle of the clamping unit. The steel structure hoisting device is installed with a transmission unit and a clamping unit in the clamping mechanism, and the electric telescopic pump body in the transmission unit drives the telescopic rods at both ends to extend simultaneously. During the extension process, the four clamping and fixing claws clamp toward the middle at the same time, so as to achieve the purpose of clamping and fixing the pipe.

[0003] The invention with announcement number CN117326445A discloses a stable lifting device for PC components, which connects a gravity block to the lower end of a telescopic member, and then rotates the gravity block through a rotational action, thereby allowing the center of gravity offset during the entire adjustment process to offset the center of gravity offset of the PC component.

[0004] However, the above-mentioned lifting equipment with stabilization function still has the following problems in actual use: although the lifting operation is realized by the lifting equipment in conjunction with the lifting steel cable, this type of lifting method mainly uses longitudinally distributed steel cables to achieve retraction and extension, and it is difficult to avoid lateral swing and tilt in the port environment. At the same time, the force-bearing parts of this type of lifting equipment cause wear during long-term sliding, and it is difficult to ensure the stability of the moving part and the supporting part, and the stability of the lifting operation cannot be met.

[0005] Therefore, we propose a self-stabilizing lifting and mounting mechanism for mechanical equipment to solve the above-mentioned problems. Summary of the invention

[0006] The purpose of the present invention is to provide a self-stabilizing lifting and installation mechanism for mechanical equipment, in order to solve the problem that the existing lifting operation is realized by lifting equipment in conjunction with lifting cables, but this type of lifting method mainly uses longitudinally distributed cables to achieve retraction and release, and it is difficult to avoid lateral swing and tilt in the port environment.

[0008] Preferably, the bottom ends of the movable rollers symmetrically arranged on the top surface of the stabilizing platform are fitted against the lower outer wall of the hoisting cross frame, and the rotation of the symmetrically arranged movable rollers drives the stabilizing platform to slide and adjust below the hoisting cross frame.

[0009] Preferably, the stabilizing mechanism includes a driving shaft, and the driving shaft is rotatably arranged at the inner center position of the stabilizing platform through a bearing, and a driving gear is fixedly arranged at the top end of the driving shaft, and a driving rack is meshingly and slidably arranged on the front and rear sides of the driving gear.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the self-stabilizing mechanical equipment lifting and installation mechanism drives the adjustable lifting platform to lift and install mechanical equipment of different specifications through the lifting wheel group of the stabilizing platform, and at the same time, the stabilizing slide plate of the stabilizing mechanism moves in the opposite direction with the traction wheel group, thereby ensuring the moving stability and reducing the tilting and swinging in different lifting environments.

At the same time, the fixed extension side arm inside the extension bracket drives the lifting hook to move, so as to be hoisted on the side of the mechanical equipment to achieve the limiting effect.

[0017] 2. The moving rollers on the top of the stabilizing platform are in contact with the lifting cross frame so that the stabilizing platform can be moved by the rotation of the moving rollers.

[0020] After the positioning slider and the traction wheel group move outward, the auxiliary stabilizing platform improves the balance during the movement. At the same time, the movable positioning slider and the traction wheel group can reduce the occupied area when working in different environments, and the work can be extended only when the stability effect needs to be improved.
