Problems solved by technology
The traditional storage brackets on the deck of small boats are often erected and lowered by human power, or are fixed structures. The human-driven brackets have a low degree of automation and a long operating time; for rescue boats that require high speed Flawed
If a fixed bracket is used, it requires a lot of space and is not suitable for built-in installation. It also requires a lot of height for the boat frame

Embodiment Construction
[0015] The present invention is described in more detail below in conjunction with accompanying drawing example:
[0016] combine Figure 1-5 , The technical solution adopted in the present invention is: a part of the bracket is fixed, that is, the fixed arm 1. A part of two triangular brackets, one of which is composed of cylinder I6, movable arm I4 and deck through shaft III5, shaft IV8 and shaft I2; the other triangular bracket is composed of hydraulic cylinder II13 through shaft VII14, shaft V11 and shaft VI12 , active arm II15 and the deck; through the axis IV8, axis II3, axis VI12 and axis VII14, the pull rod 9, the active arm I4, the active arm II15 and the deck form a four-bar linkage mechanism, which is driven by the oil cylinder I6 and the oil cylinder II13.
[0017] The bracket is installed at a suitable position on the inner deck of the cabin. The upright and down of the bracket are realized by two hydraulic cylinders equipped with hydraulically controlled one-way...

The invention aims to provide a hydraulic driving boat supporting frame which comprises brackets and a draw bar, wherein each bracket comprises a base, a hydraulic cylinder, a movable arm, a fixed arm, a first shaft, a second shaft, a third shaft, a fourth shaft, a first connecting rod and a second connecting rod, wherein the movable arm, the first connecting rod and the second connecting rod form into a triangular support; the fixed arm is fixedly arranged on the deck of a boat; the fixed arm and the movable arm are connected by the first shaft; the first connecting rod and the second connecting rod are connected by the second shaft; the bottom of the hydraulic cylinder is arranged on the base by the third shaft; the upper part of the hydraulic cylinder is connected with the second connecting rod by the fourth shaft; the two brackets are symmetrically arranged; and the draw bar is connected with the two fourth shafts for respectively connecting with the upper part of the hydraulic cylinder on the two brackets. According to the hydraulic driving boat supporting frame, the installation height of a contracting and releasing device can be reduced, the automation degree of the contracting and releasing is increased, the contracting and releasing rapidity of a small boat is improved, and self-locking can be performed by the hydraulic driving boat supporting frame, and the hydraulic driving boat supporting frame has the advantages that the installation space of the boat supporting frame is reduced, and the operation rapidity of the contracting and releasing device of the small boat is improved.
Description
technical field [0001] The invention relates to an escape device at sea, in particular to a storage mechanism for an escape boat at sea. Background technique [0002] In civilian technology, it is important to utilize the dinghy retractable device to retract and deploy the dinghy from the mother ship, and the dinghy bracket of the retractable device is installed on the deck. The traditional storage brackets on the deck of small boats are often erected and lowered by human power, or are fixed structures. The human-driven brackets have a low degree of automation and a long operating time; for rescue boats that require high speed Flawed. If a fixed bracket is used, it requires a lot of space and is not suitable for built-in installation. It also requires a lot of height for the boat frame. Contents of the invention [0003] The purpose of the present invention is to provide a hydraulically driven dolly that improves the operating speed of the retracting device and reduces t...
