Description

Technical Field

[0001] The utility model belongs to the technical field of water walls, and particularly relates to an interlocking alarm device for hoisting a water wall tube panel. Background Art

[0002] The boiler water wall tube, simply referred to as the water wall, is a kind of metal pipe laid on the inner wall of the boiler furnace to absorb the radiant heat released by the furnace flame and high-temperature flue gas, and is mainly used to cool and protect the boiler furnace wall.

[0003] The water wall tube panel is mostly formed by welding a plurality of steel pipes distributed in a linear array, with a relatively large volume and heavy mass. When workers hoist the water wall tube panel, the water wall tube panel is prone to tilt and side deviation. When the water wall tube panel tilts and side deviates, it is likely to cause relatively serious safety accidents, and the safety performance is poor. Content of the Utility Model

[0004] The purpose of the utility model is to provide an interlocking alarm device for hoisting a water wall tube panel to solve the above problems.

[0005] In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

[0006] An interlocking alarm device for hoisting a water wall tube panel includes a lifting beam. A hook is arranged on the top surface of the lifting beam. A balance sensor, a buzzer and a warning light are also arranged on the lifting beam. The balance sensor is respectively connected with the buzzer and the warning light. Bearing seats are symmetrically arranged at both ends of the lifting beam. A lead screw is arranged between the bearing seats. A motor is arranged on the bottom surface of the lifting beam. The lead screw is connected with the motor. Sliding distance adjustment mechanisms are symmetrically arranged on both sides of the motor. A grab hook is arranged at the bottom of the sliding distance adjustment mechanism. The grab hooks of the two sliding distance adjustment mechanisms are arranged facing each other. A water wall tube panel is arranged between the grab hooks.

[0007] In order to further implement the utility model, the sliding distance adjustment mechanism includes a slider and a connecting seat arranged at the bottom of the slider. A threaded hole is arranged in the slider. The lead screw passes through the threaded hole. The grab hook includes a pulling arm and a claw body fixedly arranged at the bottom end of the pulling arm. The central axis of the claw body is perpendicular to the central axis of the pulling arm. A group of pulling arms are arranged on the connecting seat. A hinge connection is arranged between the pulling arm and the connecting seat.

[0008] In order to further implement the utility model, the motor adopts a double-shaft motor. One end of the lead screw is connected with the motor through a coupling, and the other end is sleeved with a bearing. The bearing is arranged in the bearing seat.

[0009] In order to further implement the utility model, a through groove is arranged on the bottom surface of the lifting beam. The bearing seats are clamped at both ends of the groove. The slider is in a "convex" shape. The top end of the slider passes through the groove. The top surfaces of the flange on both sides of the slider are in contact with the bottom surface of the lifting beam.

[0010] To further implement the present utility model, the hook, the balance sensor and the motor are arranged on the central axis of the hanging beam.

[0011] The beneficial effects of the present utility model compared with the prior art are as follows:

[0012] The hanging beam designed in the present utility model has a cross-sectional appearance in the shape of the English letter "C". A balance sensor is fixedly installed in the middle position at the front end of the hanging beam through bolts. The balance sensor is electrically connected to the buzzer and the warning light. When the water-cooled wall tube panel is laterally deflected during the hoisting operation, the balance sensor will send an electrical signal to the electrically connected buzzer and warning light, and the buzzer and the warning light are used for reminder and warning, improving the safety performance of the water-cooled wall tube panel during hoisting.

[0013] At the middle position of the inner wall of the bottom groove of the hanging beam of the present utility model, a motor is fixedly installed through a motor seat. The motor is a double-shaft motor, and the output ends of the motor are respectively fixedly connected to one end of a lead screw through couplings. The other end of the lead screw is inserted and installed on the inner wall of the bearing seat through a bearing to form a rotating structure. The slider and the connecting seat form a "T" shape structure. A screw hole matching the thread of the lead screw is opened in the top protrusion of the slider. The double-shaft motor drives the lead screws on both sides to rotate inside the bearing seat, so that the lead screws are in threaded cooperation with the slider, driving the slider to slide in the groove, adjusting the distance between the grab hooks to adapt to the hoisting operations of water-cooled wall tube panels with different widths, which is convenient for operation.

[0014] The structure of the present utility model is reasonably designed. The water-cooled wall tube panel has high safety during the hoisting operation. The device can hoist water-cooled wall tube panels with different widths and has the advantages of being convenient for operation, thus effectively solving the problems and deficiencies in the prior art and equipment.
