Abstract
The utility model relates to a maintenance device for deformed rods of tower cranes. The maintenance device comprises a T-shaped frame with a cross beam and a vertical beam; a pair of supports positioned on two sides of the vertical beam are arranged on the cross beam and positioned on one side, away from the vertical beam, of the cross beam; a jack is arranged on the vertical beam, a screw ejector rod of the jack is positioned on one side close to the cross beam, a base of the jack is positioned on one side away from the cross beam, and a baffle fixedly connected onto the vertical beam is arranged on the rear side of the base of the jack. The maintenance device for the deformed rods of the tower cranes has the advantages of simplicity in manufacturing, convenience in operation, low maintenance cost and avoidance of influences on usability of the rods.
Description
Technical field
The utility model relates to a kind of maintenance unit of derrick crane distortion rod member.
Background technology
Derrick crane is torn open in peace, in transportation, can cause standard knot diagonal web member, crane arm pull bar, counter-jib pull bar to deform, and the open defect existing in appearance causes reusing, and must keep in repair.For some non-main stressed members, zero bar, comparatively common way is that limit impacts with sledgehammer with oxygen baking limit, or is transported to producer's maintenance, and the former easily has influence on the serviceability of rod member, and latter can be delayed maintenance cycle and strengthen maintenance cost.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of simple in structure, easy to operate, the maintenance unit of the derrick crane distortion rod member that maintenance cost is low.
The utility model adopts following scheme to realize: a kind of maintenance unit of derrick crane distortion rod member, comprise the T shape frame with crossbeam and vertical beam, described crossbeam is provided with a pair of bearing that is positioned at vertical beam both sides, described bearing is positioned on crossbeam away from vertical beam one side, described vertical beam is provided with jack, and the spiral ejection pin of jack is positioned near crossbeam one side, and the base of jack is positioned at away from crossbeam one side, and the base rear side of described jack is provided with the baffle plate being fixed on vertical beam.
Further, the push rod front side of described jack is fixed with pressing plate.
Further, the junction of the junction of the junction of described crossbeam and vertical beam, crossbeam and bearing and vertical beam and baffle plate is equipped with reinforcement gusset.
Compared with prior art, the utlity model has following beneficial effect: this novel tower-type crane deformation rod member maintenance unit, the principle of effectively having utilized the displacement of simply supported beam under Concentrated load to be no more than permissible value is revised distortion rod member, simple in structure, easy to use, the method that baking impacts relatively can not affect the stress performance of rod member, can directly use at the construction field (site), relatively be transported to producer's maintenance, greatly shortened maintenance cycle, and do not produced cost of transportation.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment organigram;
Number in the figure explanation: 1-crossbeam 2-vertical beam 3-bearing 4-jack 5-baffle plate 6-pressing plate 7-gusset 8-is out of shape rod member.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below will, by specific embodiment and relevant drawings, the utility model be described in further detail.
As shown in Figure 1, a kind of maintenance unit of derrick crane distortion rod member, comprise the T shape frame with crossbeam 1 and vertical beam 2, described crossbeam 1 is provided with a pair of bearing 3 that is positioned at vertical beam 2 both sides, described bearing 3 is positioned on crossbeam 1 away from vertical beam 2 one sides, and described vertical beam 2 is provided with jack 4, and the spiral ejection pin of jack 4 is positioned near crossbeam 1 one sides, the base of jack 4 is positioned at away from crossbeam 1 one sides, and the base rear side of described jack 4 is provided with the baffle plate 5 being fixed on vertical beam.
In the present embodiment, can be stressed even in order to make to be out of shape rod member 8, the push rod front side of described jack 4 is fixed with pressing plate 6, and leaves and can hold the space that is out of shape rod member 8 between pressing plate 6 and described bearing.
In the present embodiment, described crossbeam 1 is equipped with reinforcement gusset 7 with junction and the vertical beam 2 of bearing 3 with the junction of baffle plate 5 with junction, the crossbeam 1 of vertical beam 2.
The maintenance unit using method of this derrick crane distortion rod member is: distortion rod member 8 is lain in a horizontal plane on crossbeam 1, deformation place is towards vertical beam 2 one sides, manually adjusting jack 4 makes pressing plate 6 contact completely with the variant part of distortion rod member 8, adjusting jack 4 slowly ejects its push rod, until the variant part of distortion rod member 8 is while bending round about 10mm left and right, keep unclamping jack 4 after 10 minutes, and at deformation place touch-up paint, complete correction work.
Above-listed preferred embodiment; the purpose of this utility model, technical scheme and advantage are further described; institute is understood that; the foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
