(1) The connecting rod mechanism is used as a supporting component of the device, and plays a role in automatically bearing, limiting and stopping the life raft when the device is used.
(2) The length and the size of the connecting rod mechanism are adjustable, and the connecting rod mechanism can be suitable for life rafts with different sizes.
(3) The omnidirectional Mecanum wheels can enable the device to work in a narrow space, and the application scene is wide.
(4) The equipment maintenance cost is low, and the production efficiency is high.
Drawings
The invention is further illustrated by the following examples in conjunction with the drawings.
Fig. 1 is a schematic structural diagram of the present invention.
In the figure:
1. the life raft comprises a first vertical frame, 2 first cross frames, 3 second cross frames, 4 second vertical frames, 5 first lifting devices, 6 second lifting devices, 7 first connecting rod groups, 8 second connecting rod groups, 9 fixing claws, 10 life raft storage barrels, 11 omnidirectional wheels and 12 cross rods.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
A life raft quick change aid comprising: the first vertical frame 1 and the second vertical frame 4 are used as a bearing foundation of the device and play a role in supporting the whole set of device to normally operate.
The lower extreme of first grudging post 1 is provided with two support columns, and the lower extreme of second grudging post 4 is provided with a support column, and first grudging post 1 and second grudging post 4 are three point support with ground. First crossbearer 2 is provided with to the top of first grudging post 1, and the top of second grudging post 4 is provided with second crossbearer 3, is provided with the slide rail between second crossbearer 3 and the first crossbearer 2, and second crossbearer 3 and first crossbearer 2 sliding connection to it is adjustable to make the horizontal relative position between first crossbearer 2 and the second crossbearer 3. The lower ends of the first vertical frame 1 and the second vertical frame 4 are provided with moving wheels 11, and the moving wheels 11 are electric omnidirectional wheels with band-type brake locking function. The total number of the omnidirectional wheels is six, and the omnidirectional wheels are divided into three groups which are respectively arranged on the three feet of the machine frame. The three groups of omnidirectional wheels are driven by closed-loop motors to realize the moving and walking of the rack in any direction through the operation of the controller. The electric omnidirectional wheel can be electrified and locked by a band-type brake so as to solve the problem that the device needs to be held by people when the ship shakes.
The first cross frame 2 is provided with a first lifting device 5, and the second cross frame 3 is provided with a second lifting device 6. The first lifting device 5 and the second lifting device 6 are electric hoists. The lifting end of the first lifting device 5 is provided with a fixed claw 9, and the lifting end of the second lifting device 6 is provided with a fixed claw 9. Two ends of the life raft storage cylinder 10 are hung on the fixed claws 9. The first lifting device 5 and the second lifting device 6 function to lift the liferaft vertically during use of the device. Under the action of two sets of synchronously retractable electric hoists, the two steel wire ropes ensure that the life raft always keeps a state that the posture is parallel to the ground in the hoisting and putting-down processes.
The fixed claws 9 at two sides are connected through a cross bar 12, a first connecting rod group 7 is arranged between the first cross frame 2 and the fixed claws 9, and a second connecting rod group 8 is arranged between the second cross frame 3 and the fixed claws 9. The cross bars 12 may be exchanged to different lengths in order to accommodate life raft storage containers 10 of different length sizes. The first connecting rod group 7 and the second connecting rod group 8 form a connecting rod mechanism, and when the device is used, the connecting rod mechanism plays a role in automatically bearing, limiting and stopping the life raft. Meanwhile, the length and the size of the device are adjustable, and the device can be suitable for life rafts with different sizes.
In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
