Description

Technical Field

[0001] The utility model belongs to the field of hydraulic metal structures, in particular to a vertical force transmission and horizontal displacement tightening device. Background Art

[0002] In ship lifts, waterstopping at the ends of the cabin is crucial in order to allow the cabin to open and release the vessel after lifting. Once the cabin is lifted to a fixed position, it must be secured against the existing structure with a device to seal the water. Traditional fixing methods often rely on simple mechanical structures, such as screws and clamps. While these methods are simple and easy to implement, their limitations become apparent when faced with complex working conditions or situations requiring precise force control. On the one hand, traditional methods struggle to achieve precise multi-dimensional control; on the other hand, for large, heavy-loaded equipment, traditional fixing methods may not provide sufficient stability and reliability. Summary of the Invention

This utility model arranges the jacking devices symmetrically on both sides of the ship compartment. Its main function is to tighten the compartment longitudinally during docking and withstand the horizontal load acting on the compartment. By converting vertical force into horizontal displacement, it can not only adapt to various working environments, but also ensure the safety and stability of the jacking process.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] A vertical force transmission and horizontal displacement tightening device includes a tightening hydraulic cylinder, which is installed on a cylinder support. The piston rod of the tightening hydraulic cylinder is connected to a wedge block. The wedge block is used to slide in a guide groove. The wedge block cooperates with the tightening block and is used to drive the tightening block to move when the wedge block moves. The tightening block is hinged to a fixed bracket through a connecting rod.

[0006] Preferably, the tightening hydraulic cylinder is installed vertically, the piston rod of the tightening hydraulic cylinder is used to drive the wedge block to move up and down, and the wedge block is used to drive the tightening block to move laterally; the inclined surface of the wedge block fits the tightening block.

[0007] Preferably, the oil cylinder support is used for being installed on the equipment to be tightened.

[0008] Preferably, the fixing bracket is used for being installed on the device to be tightened.

[0009] Preferably, the wedge block is slidably mounted on the wedge block track.

[0010] Preferably, the connecting rod and the fixed bracket are connected by a connecting rod connecting shaft, and the connecting rod and the wedge block are connected by a wedge block connecting shaft. The connecting rod connecting shaft is used to hinge the connecting rod and the fixed bracket and keep it rotating at a certain angle; the wedge block connecting shaft is used to hinge it and the connecting rod and keep it rotating at a certain angle.

[0011] The utility model can achieve the following beneficial effects:

[0012] 1. This utility model places the jacking devices symmetrically on both sides of the cabin. Their primary function is to longitudinally jack the cabin during docking and withstand horizontal loads acting on the cabin. By converting vertical force into horizontal displacement, the system not only adapts to various working environments but also ensures safety and stability during the jacking process.

[0013] 2. The wedge-shaped block and track design efficiently converts vertical hydraulic power into horizontal tightening force, achieving force direction conversion and making tightening operations easy even in space-constrained environments. The entire device adopts a modular design, with components connected by shafts and connecting rods. This not only creates a compact structure but also allows for flexible layout adjustments to suit different application scenarios, making it highly adaptable.

[0014] 3. The inclined self-locking mechanism between the tightening block and the wedge block ensures that the tightening state will not be easily changed even if there is a sudden power outage or hydraulic system failure during the tightening process, thereby improving the safety of the operation. The connections between each component are fixed with reliable hinges, which can maintain stable performance under heavy loads. BRIEF DESCRIPTION OF THE DRAWINGS
