Description

Salvage ship unloading positioning device

technical field

The invention relates to a salvage ship unloading positioning device, which belongs to the field of water salvage equipment.

Background technique

At present, there is no mature equipment available for salvage work in shallow waters. For example, troops may sink into the water due to amphibious equipment failure or damage during training or confrontation between the two armies, and there is an urgent need for a mobile and flexible small-scale equipment to carry out rescue. A kind of quick disassembly type catamaran salvage ship that occurred recently has adopted the modular structure of quick disassembly assembly, and volume is small, light in weight, simple and safe and reliable hoisting device is housed in its front and rear connecting bridge. When the salvage ship transports the salvaged object in the water to the shore, its weight load should be transferred to the structure of the salvage ship by the hoisting device. How to unload the load has become a key problem that needs to be solved urgently.

Contents of the invention

In order to make the lifting device of the quick-detachable catamaran salvage ship not loaded during the non-rescue lifting time, the present invention provides an unloading positioning device dedicated to the lifting device, which should be compatible with the module of the above-mentioned salvage ship The structures are combined together, do not occupy space alone, are not easily damaged by changes in external conditions, are light in weight, small in size, easy to operate, safe and reliable.

The technical solution adopted by the present invention to solve the technical problem is: a salvage ship unloading positioning device, which mainly includes a manipulation mechanism. It also includes two hangers, the above-mentioned operating mechanism is hingedly connected by the casing and the pull rod through the pin column, the pull rod and the two connecting rods are hingedly connected by the pin column, a control rod passes through the sleeve, and the sleeve is connected to the connecting bridge. The lugs are hinged through the pins. There is a hanging weight under the pull rods and the hinge pins of the two connecting rods. The upper parts of the two hangers are connected in rotation with the lugs fixed on the connecting bridge structure. Each connecting rod The upper ends of the hangers are respectively hinged with the pin posts of the hanger, and a limit strut is provided at one place on the hanger. The above-mentioned hanger is welded together by rotating rod, cross bar, hanging rod and two longitudinal rods to form a frame structure, and two ends of rotating rod can be movably inserted into the holes of the lug plates fixed on the connecting bridge. Limiting struts are provided at the lower ends of the opposite sides of the two longitudinal bars of each hanger.

The guiding ideology of the above-mentioned technical scheme is: the unloading positioning device sets the operating mechanism and the two hangers in the front and rear connecting bridges of the salvage ship, on the one hand, the space in the connecting bridge is fully utilized, and on the other hand, the unloading positioning device The device is not easily damaged when the external conditions change; the unloading positioning device is matched with the ring seat in the lifting device, and the ring seat can be automatically seated on the hanger of the unloading positioning device, so that the salvaged objects on the ring seat The weight is transferred to the front and rear connecting bridge structures through the hanger, and the lifting device is already in the unloaded state at this time.

The beneficial effects of the present invention are: the unloading and positioning device specially used for the double-body salvage ship sets the operating mechanism and the two hangers in the front and rear connecting bridges of the salvage ship, and is connected with the ring seat in the lifting device. Cooperate, when the lifting ring seat sits on the hanger of the unloading positioning device, the lifting device can be in the unloading state. The unloading positioning device realizes the combination with the module structure of the salvage ship, does not occupy space alone, is not easily damaged by changes in external conditions, is light in weight, small in size, simple in operation, safe and reliable. At the same time, the bearing time of the lifting device is shortened, which can prolong its service life.

Detailed ways

In Fig. 1,2,3 embodiment, it mainly comprises an operating mechanism and two hangers 5. The operating mechanism is hingedly connected by the sleeve 1 and the pull rod 2 through the pin 1b, and the pull rod 2 and the two connecting rods 3 are hinged through the pin 4a. A control rod 1a passes through the bushing 1, and the bushing 1 is hingedly connected with the ear plate 7 on the connecting bridge via the pin post 1c. Below the hinge pin post 4a of pull bar 2 and two connecting rods 3, hanging weight 4 is arranged. The tops of the two hangers 5 are rotatably connected with the lugs 6 fixed on the connecting bridge structure, and the upper ends of each connecting rod 3 are hingedly connected with the hangers 5 through the pin posts 3a respectively. In Fig. 1, when the lower ends of the two hangers 5 were all in the loading position 5a, the hanger plate 8a on the ring seat 8 would be seated on the hanger 5e at the lower end of the hanger 5. When the ring seat 8 is to be put into the water, the control rod 1a is pulled out from the casing 1 and pressed down by a person. When the pull rod 2 moves up, the two connecting rods 3 are opened, and the two hangers 5 are pushed to the lug plate. 6 is the center rotation, the lower end of hanger 5 is forwarded to unloading position 5b by bearing position 5a, at this moment suspension ring seat 8 just can put down operation. When salvaging and hoisting, there is no need to press down the joystick 1a. When the ring seat 8 rises, the hanger 5 will be knocked away automatically. 5 can get back to the limit position automatically, and now the hanging head is lowered again, and the ring seat 8 will be automatically seated on the hanging rod 5e. In Figures 4 and 5, the hanger 5 is welded together by a rotating rod 5c, a cross bar 5d, a hanging rod 5e and two longitudinal rods 5f to form a frame structure, and the two ends of the rotating rod 5c are movably inserted and fixed on the connecting bridge In the hole of the upper ear plate 6. A limit brace 5g may also be provided at the lower end of the opposite side of the two longitudinal bars 5f of each hanger 5 . In FIG. 6 , four hanging rod plates 8 a are arranged on the hanging ring seat 8 , and an arc-shaped positioning opening 8 b corresponding to the hanging rod 5 e is provided under the hanging rod plate 8 a. When the lifting device is unloaded, the ring seat 8 is firmly seated on the hanging rod 5e of the hanger 5 by the arc-shaped positioning opening 8b.
