Embodiment 1

[0036] A method for adjusting the hoisting point deviation of a gate hoist, comprising the following steps:

[0037] a. Install the lifting point deviation adjustment equipment on the rack;

[0038] b. Install the hoist wire rope, and adjust the wire ropes at the two lifting points until the length is the same;

[0039] c. Adjust the balance of the two lifting points by adjusting the swing beam on the lifting point deviation adjustment device. On the side of the lifting point that bears a large load, the swing beam swings downward to loosen the wire rope; on the side of the lifting point that bears a small load, The swinging beam swings upwards to tighten the wire rope to dynamically adjust the balance of the two lifting points.

[0040] This embodiment is the most basic implementation mode, a, install the lifting point deviation adjustment equipment on the frame; b, install the hoist wire rope, adjust the wire ropes of the two lifting points until the length is consistent; c...

Embodiment 2

[0042] A method for adjusting the hoisting point deviation of a gate hoist, comprising the following steps:

[0043] a. Install the lifting point deviation adjustment equipment on the rack;

[0044] b. Install the hoist wire rope, and adjust the wire ropes at the two lifting points until the length is the same;

[0045] c. Adjust the balance of the two lifting points by adjusting the swing beam on the lifting point deviation adjustment device. On the side of the lifting point that bears a large load, the swing beam swings downward to loosen the wire rope; on the side of the lifting point that bears a small load, The swinging beam swings upwards to tighten the wire rope to dynamically adjust the balance of the two lifting points.

[0046] In the step c, the swing beam is the balance beam 3 .

[0047] The suspension point deviation adjustment device is a fixed pulley device.

[0048] Described fixed pulley device comprises pulley block, the first support base 1, the second su...

Embodiment 3

[0053] A method for adjusting the hoisting point deviation of a gate hoist, comprising the following steps:

[0054] a. Install the lifting point deviation adjustment equipment on the rack;

[0055] b. Install the hoist wire rope, and adjust the wire ropes at the two lifting points until the length is the same;

[0056] c. Adjust the balance of the two lifting points by adjusting the swing beam on the lifting point deviation adjustment device. On the side of the lifting point that bears a large load, the swing beam swings downward to loosen the wire rope; on the side of the lifting point that bears a small load, The swinging beam swings upwards to tighten the wire rope to dynamically adjust the balance of the two lifting points.

Abstract

The invention discloses a method for adjusting deviation of a hoisting point of a hoist, and belongs to the technical field of opening and closing of gates of hydropower stations. The method comprisesthe steps of a, mounting a hoisting point deviation adjusting device on a rack; b, mounting hoist steel wire ropes; and adjusting the steel wire ropes of two hoisting points to be consistent in length; and c, adjusting the two hoisting points to realize balancing through a swinging beam on the hoisting point deviation adjusting device; downwards swinging the swinging beam at one side, bearing high load, of each hoisting point, and releasing the corresponding steel wire rope; downwards swinging the swinging beam at one side, bearing small load, of each hoisting point; coiling the correspondingsteel wire rope, and thus finishing the dynamic adjusting of the balance of the two hoisting points. According to the method, the hoisting point deviation adjusting device is adopted and is capable of timely dynamically adjusting the two hoisting points to realize balancing while the hoist runs, and thus stopping for repairing is saved; the hoist running stability can be ensured; and the adjusting is flexible, simple and convenient.

Description

technical field [0001] The invention relates to the technical field of gate opening and closing of a hydropower station, in particular to a method for adjusting the deviation of a hoisting point of a hoist. Background technique [0002] The gate hoist of the double lifting point hydropower station is a special lifting equipment widely used in the hydropower industry, and is mainly used for the opening and closing of gates and trash racks. [0003] The gate hoist of the hydropower station with double lifting points has high requirements on the deviation between the two lifting points. When there is a deviation of the lifting points, there will be uneven force between the two lifting points. One lifting point bears a small load, and the other lifting point The heavy load, even exceeding the rated lifting load, causes overload on one side of the lifting point, which seriously affects the safe operation of the gate hoist of the hydropower station with double lifting points.
