Embodiment Construction

[0020] Referring to Fig. 1 and Fig. 2, according to a factory test method of a large-scale hoist of the present invention, two test hoists are used, one of which is the tested hoist 1 and the other is the loading hoist 2, or two test hoists are used in the test. The hoists alternate with each other. Two identical hoist prototypes are used to facilitate mutual loading during type testing.

[0021] The present invention adopts the following steps to carry out type and factory tests:

[0022] Place the two test winches face to face and close together, and connect the two drums of the winches with wire rope 3 (as shown in Figure 2), so that the tension of the steel wire rope becomes the internal force of the winch, and the winch does not need to be fixed to the ground.

[0023] An intermediate hydraulic cylinder support device 4 is added between the two test winches, preferably two sets of support devices for the connection between the winches are used to adjust the tension balan...

Abstract

The invention is concerned with test method for large windlass before leaving factory. It adopts two windlasses to carry the draw loading test and it will carry all tests according to the provision, such as static load, dynamic load, rating speed and braking capability. Put one tested windlass and one load windlass face to face and connect the two roll canisters of windlass with steel wire. The pull of steel wire is the internal force of windlass while the windlass does not need to be fixed with the ground. Add middle hydraulic pressure oil jar support equipment between the two tested windlasses to adjust the pull of two steel wires. The invention only uses the drive system of windlass without adding expert test equipment and solves the loading course test problem to large and heavy windlass to save lot of investment and test field. The type and test method of large windlass fit for test to double uniting roll canister, single roll canister and all kinds of roll canister.

Description

technical field [0001] The invention relates to a hoist, in particular to a type of a large hoist and a factory test method. Background technique [0002] Usually, after completing the factory manufacturing, installation and debugging, the large hoist must do the type and factory test, and can only be transported to the use site after passing the test. The test items of large winches include static load, dynamic load, braking performance and rotational speed, etc. These test items all require large special test equipment for tensile load. [0003] If a hoist manufacturer wants to establish and improve such a complete set of large hoist test equipment and sites, it needs to invest a lot of money and carry out large-scale construction. For the production enterprise, this is a project with huge investment and high construction difficulty. SUMMARY OF THE INVENTION [0004] The task of the present invention is to provide a new ex-factory test method for large hoists, which sol...
