The specific embodiment
Embodiment one
As shown in Figures 1 to 4, the special-purpose lifting gear of a kind of viaduct maintenance construction comprises several big parts of base, crane, electric block and hanging basket, is described in detail with regard to its structure respectively below.
Base 1 is a rectangle frame that is formed by welding by steel such as channel-section steel, square steel, weld first column 11 of a pair of hollow shape respectively in the rear and front end of base, first column wherein is rectangular steel pipe, open a circular hole 5 on the top of first column, when making base, the size of base will adapt with the wagon box that needs carry out the vehicle of carrying.
Crane 2 is formed " door " font by two second columns 21 and second crossbeam 22, use rectangle steel to carry out welding production, wherein second column 21 and first column match, and on second column, be provided with a plurality of circular holes 5 from top to bottom, cooperating an alignment pin by the circular hole between two columns, two columns can be adjusted in short transverse, be formed a height retaining mechanism, this is to understand easily.Second crossbeam 22 also is a rectangular steel pipe, inside has a chamber, in second crossbeam 22, be provided with telescopic first crossbeam 31, the bearing 32 that between is provided with guiding is slidingly matched, and be respectively equipped with circular hole 5 ' at first crossbeam and second crossbeam, wherein first crossbeam is provided with a plurality ofly, and between the two circular hole cooperates alignment pin to form a horizontal retaining mechanism, is used for regulating the horizontal position of electric block.
First crossbeam 31 wherein is i iron, fixes an electric block 41 by the U-shaped fixture respectively in the same outer end of first crossbeam 31, and hanging basket 43 is connected to electric block 41 by wire rope 42, and electric block 41 drives the lifting of hanging basket.Wherein between hanging basket and first crossbeam safety rope servicing unit being set is prior art, repeats no more.
When constructing under bridge, as Fig. 5, base 1 integral body is placed in the wagon box of vehicle 7, and then be equipped with a diesel-driven generator 12, moving cucurbit is used in the electric energy that sends power supply.Vehicle 7 is reached a side of viaduct 8, take a motor-driven parking stall, then crane 2 is risen to proper height, lock and locate with alignment pin, then with the first cross bar also outer correct position that extends, personnel stand in the hanging basket 43 then, utilize electric block hanging basket can be transferred to the position that makes things convenient for personnel to construct, as shown in Figure 5, behind the point of having constructed, vehicle 7 directly moves ahead and gets final product, and is safe and reliable.
When bridge is constructed, as Fig. 6, base 1 integral body is placed in the wagon box of vehicle 7, and then be equipped with a diesel-driven generator 12, the electric energy that sends supply electric block uses.Vehicle 7 is reached on the viaduct 8, take a motor-driven parking stall, crane 2 need not to rise, then first cross bar is extended correct position outward, personnel stand in the hanging basket 43 then, utilize electric block hanging basket can be transferred to the position that makes things convenient for personnel to construct, as shown in Figure 5, constructed behind the point, vehicle 7 directly moves ahead and gets final product, and is safe and reliable.
Simultaneously as required, be provided with balancing weight 13 at base 1, the quantity of balancing weight and can match as required with material prevents from toppling in the course of work.Need to prove that in addition described hanging basket is the working space that is formed by angle steel, steel pipe and steel plate welding, form latticedly in the side of hanging basket, can form effective protection to the constructor who stands in wherein.Establish simultaneously an auxiliary insurance between hanging basket and electric block, the structure of the hanging basket of this and existing work high above the ground is similar substantially with safeguard structure.
This structural formula is the simplest, and manufacturing cost is also minimum, and shortcoming is to regulate height and need manual adjustment when extending laterally, and general two people can finish.
Embodiment two,
Be with embodiment one difference: retaining mechanism does not re-use simple alignment pin and locks and locate.As Fig. 7, comprise gear 61, tooth bar 62, worm-and-wheel gear 63 and drive end 64, tooth bar 62 is installed on second column, gear 61 is installed on first column, and gear is connected with worm-and-wheel gear, and drive end 64 is a handwheel, the driving worm-and-wheel gear action of drive end.This mechanism in like manner can use equally and first crossbeam and second crossbeam of level between, be used for driving stretching out and withdrawal of first crossbeam.Utilize the self-locking property of worm-and-wheel gear can finish the locking purpose, easy to use, this structure goes between two columns or/and between two crossbeams.
As a kind of distortion of present embodiment, described drive end is a motor, forms automatic version.
Embodiment three,
As shown in Figure 8,
Be with embodiment one difference, use first oil cylinder 91 to drive between first column and second column, namely, first oil cylinder, 91 two ends are installed on the crossbeam between second crossbeam and the column by pin respectively, just can drive the stretching motion of two columns like this by the jacking effect of first oil cylinder 91.In like manner, second oil cylinder 92 can be installed also between first crossbeam and second crossbeam, drive the stretching motion of first crossbeam on left and right directions by second oil cylinder 92.Understand easily, this structure need cooperate a Hydraulic Station and hydraulic control system, is used for reasonably its motion of control.
The advantage of this structure is, the function that can satisfy automatic lifting and extend laterally is similar to a hydraulic equipment, and shortcoming is that manufacturing cost is high slightly.
Embodiment four,
Also be the elevating movement that hydraulic system provides, as shown in Figure 9, be that with embodiment three differences first and second columns (11,21) come down to a hydraulic jack, with the auxiliary elevating movement of finishing on short transverse.In like manner, first crossbeam and second crossbeam (31,22) also can adopt the hydraulic jack roof construction.
Understand easily, the manually locking of above-mentioned location, worm-and-wheel gear, Driven by Hydraulic Cylinder and hydraulic jack roof construction all have driving and positioning function, can carry out any combination, adopt the hydraulic jack roof construction as column, crossbeam adopts the alignment pin manual adjustment.
More than each embodiment speciality is respectively arranged, each unit can select suitable version construct according to the actual requirement of engineering of oneself, its efficiency of construction all will be higher than the mode of existing crane lifting operation far away.
Embodiment recited above is described preferred embodiment of the present invention; be not that scope of the present invention is limited; design under the prerequisite of spirit not breaking away from the present invention; the relevant technical staff in the field all should expand as in the determined protection domain of claims of the present invention various distortion of the present invention and improvement.
