Description

Counterweight beam

Technical field

The utility model relates to a kind of carrier bar, particularly a kind of counterweight beam.

Background technology

According to special equipment administrative provisions, all kinds of elevator machineries that enterprise uses in use all need to do periodic verification and detect, and only can continue to use after detection is qualified.In mechanical verification project, rated load weight hoisting test is one of extremely important test item in required verification project.The standard counterweight that rated load weight hoisting test uses is generally registered cube iron block, and each cube iron block weight is generally 5 tons or 10 tons.

But the crane rating scope used due to enterprise is uneven, little then tens tons, greatly then go up kiloton, therefore the balance weight needed during the verification of elevator machinery load is varied.During as done large-tonnage rated load weight hoisting test, needing the foundary weight block by standard to stack layer by layer because the standard counterweight in this hoisting test is limited in scope, is that this hoisting test adds operation easier and is difficult to ensure safety thus.

Utility model content

The technical problems to be solved in the utility model is the high and unsafe defect of the rated load weight hoisting test operation easier in order to overcome prior art, provides a kind of counterweight beam being suitable for multiple balance weight requirement.

The utility model solves above-mentioned technical matters by following technical proposals:

A kind of counterweight beam, its feature is, comprise one for the beam main body of stacking standard counterweight, be fixedly connected on four root posts on described beam main body four angles and hoist cable, described hoist cable comprises two groups of hangers, for the shackle that connects hanger described in two groups and the wire sling be connected with described hanger, described hoist cable is arranged at the end of described beam main body by described shackle correspondence.

Preferably, described column is provided with auxiliary hanger, wire sling and described column is tied up by the metallic cable being arranged in described auxiliary hanger.

Preferably, the weight sum of described counterweight beam and described hoist cable is 67.25 tons.

Preferably, the total counterweight volume in described beam main body is 500 tons.

Preferably, the material of described column is shaped steel.

Preferably, described counterweight beam also includes secondary weight beam, and described secondary weight beam comprises one for the carrier bar of stacking counterweight, and the both ends of described carrier bar are provided with the bindiny mechanism for being connected with described hanger.

Preferably, described bindiny mechanism is otic placode parts, and described otic placode parts are provided with the lifting hole(eyelet) that wears wire sling.

In the utility model, above-mentioned optimum condition can combination in any on the basis meeting this area general knowledge, obtains each preferred embodiment of the utility model.

Positive progressive effect of the present utility model is:

1, the counterweight beam that the utility model provides has the suspension centre of multiple hanger composition, connects secondary weight beam, and then increase the weight of total counterweight volume by these suspension centres, realizes implementing rated load weight hoisting test to the lifting machinery of multiple counterweight requirements;

2, the counterweight beam that provides of the utility model by arranging auxiliary hanger on column, when the standard counterweight that beam main body stacks is too high, causes the overall center of gravity of counterweight beam too high and then cause potential safety hazard.By auxiliary hanger, wire sling and column are tied up and tighten, thus the danger preventing counterweight beam from toppling, ensure hoisting test safety;

3, the beam main body baseplane of counterweight beam that provides of the utility model is large and smooth, beam main body baseplane stacks standard foundary weight (current standard foundary weight schedule weight about 5 ~ 10 tons), when total counterweight volume (comprising deadweight 67.25 tons) reaches 500 ton hours, can guarantee that counterweight beam is not toppled.

4, the material of the column of counterweight beam that the utility model provides adopts shaped steel, and namely easy construction is convenient to machine up and connection, is also easy to remove, and reduces manufacturing cost.
