Boat is usually equipped with air tank, so that boat has enough buoyancy to ensure the safety of boat and personnel on board after water. Lifeboat is generally hoisted by steel wire rope, and suspended on the davit. Steel wire rope is fixed and wound on the drum of launching device, and monthly operation such as boat release and boat recovery is carried out, and when the steel wire rope reaches the scrap period, the steel wire rope needs to be replaced in time to ensure the safety of personnel escaping from sea device.
[0003] In the past, when the original steel wire rope is removed and released, the manual hand crank is inserted into the steel wire rope release hole of the launching device, connected with the input end of the drum reducer, and the drum reducer is driven to rotate the drum by manual driving of the hand crank to release the steel wire rope. Such release mode has the following problems:
[0004] 1. Manual hand crank requires high physical strength, and the process is particularly labor-intensive. General operators will appear exhausted when releasing about 10 meters, and need a certain time to recover physical strength, which causes the progress of steel wire rope replacement to stop, and seriously affects the operation progress.
[0005] 2. Manual hand crank requires more personnel and higher qualification of operators. Each launching device is equipped with two steel wire ropes, and in the case of five operators, at least two days are required to replace the steel wire rope by manual hand crank. During the replacement of steel wire rope, lifeboat is in an unusable state, which increases the risk of escape in case of platform emergency. SUMMARY
[0006] The utility model aims at providing a kind of auxiliary tool for the steel wire rope of lifeboat launching device replacement, which can improve the working efficiency of steel wire rope replacement and recover the usable state of lifeboat faster.
[0007] To solve the above technical problems, the utility model adopts the following technical scheme: a kind of auxiliary tool for the steel wire rope of lifeboat launching device replacement, characterized by: including liftable support frame, automatic wrench, universal joint and the connecting head matched with the input end of the drum reducer of launching device;The automatic wrench is installed on the top of liftable support frame, and the connecting head is connected with the automatic wrench by universal joint.
[0008] Further, the liftable support frame comprises a support with a threaded column, a support leg connected to the support, a limiting nut and a lifting sleeve threadedly connected to the threaded column, a bracket fixedly connected to the upper end of the lifting sleeve, and a clamp connected to the bracket; the automatic wrench is placed on the bracket and fixed after being connected by the clamp.
[0009] Further, the support leg is connected with a universal wheel with a locking structure.
[0010] Further, the top of the universal wheel with the locking structure is provided with an adjusting threaded column, and a screw hole is formed in the support leg, and the universal wheel is connected to the screw hole through the adjusting threaded column.
[0011] Further, the liftable support frame is made of stainless steel.
[0012] Further, the automatic wrench is an electric wrench or a pneumatic wrench.
[0013] The automatic wrench is an electric wrench or a pneumatic wrench. BRIEF DESCRIPTION OF DRAWINGS
[0014] The utility model makes further explanation to the utility model with the drawings, but the embodiment in the drawings does not constitute any limit to the utility model, and other drawings can be obtained according to the following drawings without creative labor for ordinary skilled in the art.

[0018] The drawings are only used for example description, and cannot be understood as the limit to the patent; in order to better illustrate the embodiment, some components of the drawings can be omitted, enlarged or reduced, and do not represent the size of actual product; for those skilled in the art, some well-known structures and their description in the drawings can be omitted, and it is understandable. The position relation described in the drawings is only used for example description, and cannot be understood as the limit to the patent.
[0019] As Figure 1 , 2The figure shows an auxiliary tool for replacing the wire rope of a lifeboat launch device. It includes a liftable support frame 1, an automatic wrench 2, a universal joint 3, and a connector 4 that mates with the input end of the launch device's drum reducer. The automatic wrench 2 is mounted on top of the liftable support frame 1, and the connector 4 is connected to the automatic wrench 2 via the universal joint 3. The universal joint 3 eliminates slight deviations in height or left and right, ensuring the stability of the wrench during use.
[0020] like Figure 3 As shown, the liftable support frame 1 is made of stainless steel. It includes a support 11 with a threaded column 13, a support leg 12, a limit nut 14 and a lifting sleeve 15. There are three support legs 12, which are respectively threadedly connected to the support 11. The three-leg support is more stable and the three legs are installed by threads, which is convenient for disassembly and storage. The limit nut 14 and the lifting sleeve 15 are respectively threadedly connected to the threaded column 13, and the limit nut 14 is placed below the lifting sleeve 15 for limiting the height adjustment. The upper end of the lifting sleeve 15 is fixedly connected to a bracket 16; a clamp 17 is connected to the bracket 16. Specifically, the bracket 16 is provided with a U-shaped groove, one end of the clamp 17 is connected to one side of the bracket 16 by a hinge, and the other side is connected by a bolt.
[0021] During assembly, the main body of the automatic wrench 2 is placed on the U-shaped groove of the bracket 16, and then the clamp 17 is fastened and fastened with fastening bolts to ensure that the automatic wrench 2 is firmly mounted on the support frame. By designing the support frame to be height-adjustable, the limit nut 14 on the threaded column 13 is used to limit the position. After the lifting sleeve 15 is adjusted into place, the height of the automatic wrench 2 is adapted to the position of the wire rope release socket of the boat lifting device. In other words, the connector 4 of the auxiliary tool of the utility model can be inserted into the wire rope release socket and connected to the input end of the drum reducer.
[0022] Preferably, the support legs 12 are connected to universal wheels 18 with locking mechanisms. A threaded adjustment post is located at the top of the universal wheels 18, which are connected to screw holes in the support legs 12. The locking universal wheels facilitate movement and position adjustment, allowing them to be fixed during operation to prevent movement that could affect the work. Furthermore, each universal wheel is topped with a threaded adjustment post, allowing for fine-tuning to ensure the support frame is level if the ground is uneven.
[0023] During actual application, the automatic wrench 2 can be an electric wrench or a pneumatic wrench. In addition, the universal joint connection end of various specifications can be designed to adapt to the connection with different automatic wrenches.
[0024] The working process of the utility model is as follows: in use, the height of the liftable support frame 1 is adjusted according to the actual situation of the work site, and the automatic wrench 2, universal joint 3 and connecting head 4 are assembled. And the auxiliary tool is moved to the appropriate position to make the connecting head butt joint with the input end of the drum speed reducer. When the steel wire rope is replaced, the operator drives the drum to rotate to quickly release the lifeboat steel wire rope by controlling the automatic wrench; then another person recycles and winds the old steel wire rope. When the recycling and winding speed of the old steel wire rope cannot keep up with the release rhythm, the operator of the automatic wrench controls the automatic wrench to stop and pause the release of the steel wire rope, and waits for the next release. Repeat the operation until the replacement of the steel wire rope is completed.
[0025] The above only is the preferred embodiment of the utility model, and does not limit the utility model, although the utility model has been described in detail with reference to the foregoing embodiment, for the person skilled in the art, still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part technical feature. Any modification, equivalent replacement, improvement etc. that is made within the spirit and principle of the utility model, should be contained in the protection scope of the utility model.
