Technical Field

[0001] The invention belongs to the field of ocean engineering slideway beam load testing, and in particular relates to a slideway beam load testing device. Background Art

[0002] Electric or manual hoists are installed on the slide beam for equipment lifting. Due to the heavy weight of the inverted equipment, the slide beam is prone to bending and deformation during operation. Therefore, after the slide beam is installed, it is necessary to perform a load test to detect whether the strength of the slide beam can meet the later use requirements and safety requirements. During the construction of offshore oil platforms, a fall chain is often used to perform a slide beam load test.

[0003] The load test of the slide beam with a fall chain will destroy the deck plate, set a fixed hinge to fix the fall chain, and rely on manpower to pull to reach the test load. Offshore oil platforms usually have several slide beams, and one slide beam needs to be tested for loads at several test points, and the subsequent repair of the deck plate is a lot of work; in the case of a large load test, the manpower consumption is large and the fall chain is difficult to transport, which affects the efficiency and economy of the slide beam load test.

[0004] Therefore, it is urgent to design a slideway beam load test device to solve the above-mentioned problem of performing load tests on several test points of the slideway beam. Summary of the invention

[0006] To achieve the above purpose, the specific technical solution of the slideway beam load test device of the present invention is as follows: A slide beam load testing device comprises a slide beam and a slide beam sling, wherein the slide beam sling is connected to the slide beam, the slide beam sling is connected to a tension gauge via a first shackle, the tension gauge is connected to a second shackle, the second shackle is connected to a first lifting pulley, the first lifting pulley is connected to a second lifting pulley via a steel wire rope, the second lifting pulley is connected to a sling, the sling is connected to a counterweight, the steel wire rope is connected to a winch, and the winch drives the second lifting pulley connected to the steel wire rope to move upward to lift the counterweight.

[0007] Furthermore, one end of the wire rope extends out from the winch, and the wire rope passes through the second lifting pulley of the second lifting pulley and then enters the first lifting pulley of the first lifting pulley, and then passes through the first lifting pulley and then enters the second lifting pulley, so that the wire rope is evenly wound between the first lifting pulley and the second lifting pulley.

[0008] Furthermore, a fixed end of a steel wire rope is provided on the second lifting pulley, and one end of the steel wire rope passes through the first lifting pulley and is connected to the fixed end of the steel wire rope.

[0009] Furthermore, a slideway beam sling is sleeved on the slideway beam, a first shackle is sleeved on the slideway beam sling, and the first shackle is connected to the dynamometer via a first shackle pin.

[0010] Furthermore, one end of the dynamometer away from the first shackle is connected to the first lifting hook of the first lifting tackle through the second shackle.

[0011] Furthermore, the second lifting pulley is provided with a second lifting hook, the second lifting hook is hung with a sling, and one end of the sling away from the second lifting hook is connected with a counterweight block.

[0012] Furthermore, both ends of the counterweight block are provided with lifting points, and one end of the lifting belt away from the second lifting hook is sleeved on the lifting point to lift the counterweight block.

[0015] Furthermore, the slideway beam sling can be mounted on various positions of the slideway beam to perform load tests on various positions of the slideway beam.

[0016] The slideway beam load test device of the present invention has the following advantages: The steel wire rope passes through the first lifting pulley and the second lifting pulley respectively to form a pulley block, thereby reducing the tension required to reach the test load. The load value provided by the dynamometer display device is connected to the second lifting pulley through a sling to fix the second lifting pulley.
