Abstract
Disclosed is a slide rooted beam device. At present, the problem about rooting on a suspension device of a rigid beam of a coal powder type boiler is solved, and welding rigid beams at two ends meet the suspension requirements of suspension devices of relevant parts. However, the rooted beam structure applicable to suspension has effects on the expansion requirements of part of stiffening beams and effects expansion of the water cooling wall, and in expansion impediment of the water cooling wall, thermal stress can cause deformation or even blast of a water cooling pipe screen, unplanned shutdown frequency of the unit is increased and economic benefits of the unit are reduced. The slide rooted beam device structurally comprises a rooted crossbeam (4), the rooted crossbeam is groove steel or H-shaped steel and are connected with two slide clamp blocks 2, the slide clamp blocks are welded with a stiffening beam diagonal beam A (1), and the rooted beam is connected with a stiffening beam diagonal beam B (9). The slide rooted beam device is used for producing the coal powder boiler structure.
Description
technical field:
the present invention relates to a kind of sliding-type to take root boom device.
background technology:
at present; coal dust type boiler is that erecting by overhang solves problem of taking root on buckstay; welding two ends buckstay meets the suspention requirement of associated components erecting by overhang; but this girder construction of taking root being applicable to suspend in midair affects the expansion requirements of partially rigid beam, and then affect the expansion of water-cooling wall when running; under water-cooling wall swelling blockage; thermal stress can cause panelized-tube-wall section to be out of shape even booster, increases unit non-programmed halt frequency, reduces the economic benefit of unit.
summary of the invention:
above-mentioned object is realized by following technical scheme:
a kind of sliding-type is taken root boom device, its composition comprises: crossbeam of taking root, and described crossbeam of taking root is channel-section steel or I-steel, and described crossbeam of taking root is connected with 2 slip fixture blocks, described slip fixture block welds with buckstay cant beam A, and described crossbeam of taking root is connected with buckstay cant beam B.
described sliding-type is taken root boom device, described crossbeam of taking root is channel-section steel, described crossbeam and the described buckstay cant beam A of taking root overlaps, described crossbeam of taking root welds with described buckstay cant beam B, clamping lag bolt, successively through square taper liner block, described slip fixture block, described crossbeam of taking root, has reinforcement in described channel-section steel.
described sliding-type is taken root boom device, described crossbeam of taking root is channel-section steel, described crossbeam and the buckstay cant beam A of taking root overlaps, described crossbeam and the buckstay cant beam B of taking root overlaps, described slip fixture block welds with buckstay cant beam B, and clamping lag bolt is successively through square taper liner block, described slip fixture block, described crossbeam of taking root.
described sliding-type is taken root boom device, described crossbeam of taking root is I-steel, and described crossbeam and the described buckstay cant beam A of taking root overlaps, and described crossbeam of taking root welds with described buckstay cant beam B, studs is through described slip fixture block, described crossbeam of taking root
described crossbeam of taking root is connected with slip fixture block B, and described studs two ends cover has binding nut.
described sliding-type is taken root boom device, and described slip fixture block is angle steel or channel-section steel, and described slip fixture block has slotted hole.
beneficial effect:
1. the present invention is under different loads, forms spacing slideway by slip fixture block and fishbolt, and the crossbeam that makes to take root can when boiler start/ stop, and the expansion along with heating surface is slided the spacing regulated between buckstay in the slideway of constraint.Thus the surface expansion that keeps from heat is obstructed, and reduces and produces extra heat stress because of boiler start/ stop, avoids the possibility significantly changing fatigue rupture heating surface of thermal stress, thus improve the reliability of unit boiler controller system when load variations.Reduce unit because of booster non-programmed halt frequency and Unit Commitment loss, improve unit operation benefit.This kind of structure welding between buckstay cant beam of avoiding over beam of taking root affect heating surface and expands, and this kind of slide construction simply, and mounting cost is low, reasonable in design, the reliability of unit can be improved, economy, again save the cost that complicated slide construction making and installation brings.
sliding-type of the present invention boom device of taking root comprises crossbeam of taking root, slip fixture block, square taper liner block, clamping lag bolt and binding nut; Beam one end of taking root is welded in top, the buckstay cant beam A edge of a wing, and the other end is overlapped on another buckstay cant beam B edge of a wing and crossbeam two ends of taking root keep level on inclined-plane, the buckstay cant beam edge of a wing.Slip fixture block is made up of angle steel, and two slip clamp block weldings are taken root in the upper inclined surface of the buckstay edge of a wing, crossbeam side at overlap joint, clamps crossbeam of taking root up and down, forms required slideway when crossbeam of taking root runs.Crossbeam of taking root in this statement selects channel-section steel to make beam, and groove face obliquely, considers that intensity can improve beam strength at the corresponding groove face floor of two-sided full weld in crossbeam groove face of taking root.
the present invention's crossbeam two slip fixture blocks on bond end and inclined-plane of taking root form two contact surfaces.Bond end contact surface take root side, the crossbeam groove face edge of a wing for clamping lag bolt make corresponding bolt hole.In contact surface slip fixture block angle steel side by the expansion shift perforate between the buckstay cant beam calculated, the shape similar stadium of track and field Long Circle runway in hole.When cold conditions is installed, clamping lag bolt is in the deflection overlap joint buckstay cant beam central web side, side of obround opening, during hot operation, because crossbeam of taking root is distributed between buckstay cant beam A and buckstay cant beam B, one end is welded with buckstay cant beam B, buckstay cant beam spacing can expand along with heating surface and become large, causes it to move along with buckstay cant beam.Taking root crossbeam can along with heating surface expansion to mobile trend outside the central web overlapping side buckstay.
the present invention due to crossbeam A of taking root in overlap joint side contacts face perforate for circular, clamping lag bolt can along with taking root cross beam movement and moving, its running orbit in slip fixture block by near cant beam central web side to away from central web side, but to be in all the time in slip fixture block contact surface Long Circle groove.Because crossbeam selects channel-section steel, Harbin Boiler Plant standard component side taper liner block is installed additional inside the groove face edge of a wing, its effect makes the loud steadily movement of groove face of clamping lag bolt and position limiting structure that binding nut is formed, and does not produce violent shake in horizontal gird moving process.
