Abstract
A constant tension winch load test method comprises the following steps: step 1: the constant tension winch steel wire rope is led out from the winding drum and penetrates through the fixed guide wheel. Step 2: the steel wire rope penetrates out of the guide wheel and then passes through a pulley fixed on the hook head of the gantry crane. And step 3: and connecting the steel wire rope penetrating out of the pulley to a test weight block of the dock bottom. And 4, step 4: prevent that the portal crane gib head follows the pulley and removes, draw forth a steady wire rope from the gib head. And 5: the direction stabilizing steel wire rope is connected with the chain block, and the chain block provides tension for the direction stabilizing steel wire rope. Step 6: the chain block is fixedly connected with the counterweight block at the dock edge. The invention solves the problem that the semi-submersible type ocean platform constant tension winch can carry out load test under the condition that tension equipment cannot be used.
Description
Technical Field
The invention belongs to the technical field of ocean engineering, and particularly relates to a constant tension winch load test method.
Background
The winch equipment of the semi-submersible type ocean platform has a constant tension function, and a load test needs to be carried out on the function according to the requirements of a debugging program.
Disclosure of Invention
In order to solve the technical problem, the invention provides a constant tension winch load test method, which specifically comprises the following steps:
step 1: the constant tension winch steel wire rope is led out from the winding drum and penetrates through the fixed guide wheel.
Step 2: the steel wire rope penetrates out of the guide wheel and then passes through a pulley fixed on the hook head of the gantry crane.
And step 3: and connecting the steel wire rope penetrating out of the pulley to a test weight block of the dock bottom.
And 4, step 4: prevent that the portal crane gib head follows the pulley and removes, draw forth a steady wire rope from the gib head.
And 5: the direction stabilizing steel wire rope is connected with the chain block, and the chain block provides tension for the direction stabilizing steel wire rope.
Step 6: the chain block is fixedly connected with the counterweight block at the dock edge.
Furthermore, under the condition that a pulling device cannot be used, an external force required by the test is provided for the constant tension winch through the matching of the gantry crane and the pulley.
The invention uses the existing resources to complete the test work of the constant tension winch, has simple method and strong feasibility, not only saves the cost, but also solves the problem that the load test of the semi-submersible type ocean platform constant tension winch can not be carried out under the condition of using the pulling force equipment.

In the figure, 1, a constant tension winch, 2, a guide wheel, 3, a gantry crane, 4, a pulley fixed on a hook head, 5, a test balancing weight, 6, a steel wire rope, 7, a chain block and 8, the balancing weight.
Detailed Description
For the purpose of promoting an understanding of the invention, reference will now be made in detail to the present invention as illustrated in the accompanying drawings, which are provided for purposes of illustration only and are not intended to limit the scope of the invention.
Demonstration of technical feasibility:
firstly, determining the weight of the constant tension winch test load.
And secondly, selecting a proper test counterweight, a steel wire rope and a pulley.
And thirdly, calculating the tension of the steady steel wire rope through stress analysis, and keeping the stability of the hook head of the gantry crane.
As shown in fig. 1, a constant tension winch load test method specifically includes the following steps:
step 1: the steel wire rope of the constant tension winch 1 is led out from the winding drum and passes through the fixed guide wheel 2.
Step 2: the steel wire rope penetrates out of the guide wheel 2 and then passes through a pulley 4 fixed on a hook head of the gantry crane.
And step 3: and connecting a steel wire rope penetrating out of the pulley 4 to a test counterweight 5 at the bottom of the dock.
And 4, step 4: prevent that the portal crane gib head follows pulley 4 to remove, draw forth a steady wire rope 6 from the gib head.
And 5: the direction stabilizing steel wire rope 6 is connected with a chain block 7, and the chain block 7 provides tension for the direction stabilizing steel wire rope 6.
Step 6: the chain block 7 is fixedly connected with a counterweight block 8 at the dock edge.
Under the condition that a pulling force device cannot be used, an external force required by the test is provided for the constant tension winch through the matching of the gantry crane and the pulley.
