The specific embodiment
The utility model below will combine embodiment (accompanying drawing) to do description further:
are like Fig. 1,2, shown in 3; The utility model hoisting crane mainly comprises walking chassis 1; Be seated in walking and The One On The Chassisly can do 360 ° of rotating turn tables 7; Be positioned at body of the tower 2 on the turn table, be arranged on arm 3, side supports 5, the luffing brace 4 of body of the tower upper end, and part such as electric control unit; Wherein electric control unit is one group of electricity, liquid, gas integral system.
said body of the tower 2 has at least one to be to be made up of the box slip joint that at least two joints are sleeved on together with arm 3, and when spread length reaches capacity, and maintains lap 15 (referring to Fig. 5) between per two adjacent slip joints; The lower end of said body of the tower 2 is hinged on the turn table 7, and the upper end of body of the tower 2 is connected with side supports 5, luffing brace 4 and arm 3 through hinge; Wherein the quantity of side supports 5 is three, the left and right and rear side at the top of separation body of the tower 2, and luffing brace 4 is positioned at body of the tower 2 tops, and arm 3 is positioned at the front side of body of the tower 2; The jointed shaft parallel axes of said luffing brace 4 jointed shaft axis and arm 3; Said arm 2, with the side supports and the luffing brace 4 longitudinal centerline coplane separately of body of the tower rear side, and intersect (referring to Fig. 4) with body of the tower 2 longitudinal centerlines respectively; First slip joint middle part and root are provided with at least one with the pivotally attached mode respectively and are used to realize that body of the tower keeps flat or upright hydraulic actuating cylinder 13 in said body of the tower 2 lower ends, and said hydraulic actuating cylinder 13 other ends are hinged on the turn table 7.
Combine through hydraulic ram and the flexible cable that is built in its cavity between the box slip joint in
the utility model.。
like Fig. 2, shown in 3, the utility model is furnished with operator's compartment 12, clump weight 9, engine installation 11, side supports connector 6 and winch 10 on turn table 7.
respectively are provided with a side supports connector 6 with symmetrical arrangement on said turn table 7; The longitudinal centerline of said side supports connector 6 be positioned at body of the tower 2 tops about the longitudinal centerline coplane of two side supports; Each side supports connector 6 passes through drag-line 8 and is connected with its cooresponding side supports 5, and the rear sides that is positioned at body of the tower 2 tops supports through drag-line 8 and is connected with turn table 7.
During
operation, walking chassis 1 rests on the ground of work-yard, body of the tower 2 with and go up all parts, under the effect of hydraulic actuating cylinder as shown in Figure 7 13, realize hoisting, be fixed on the turn table 7 when reaching vertical state.Then, body of the tower 2 extends under the driving of the hydraulic efficiency gear that himself possessed, and is locked when reaching the hoisting height requirement.After 2 liters of tower processes of body of the tower are accomplished; The side supports 5 of the body of the tower left and right sides is connected with cooresponding side supports connector 6 on the turn table through drag-line 8 respectively and strains; The side supports 5 of body of the tower rear side is connected with turn table 7 through drag-line 8 and strains, to keep balance, stable.According to the requirement of practice of construction radius, arm 3 is flexible under the driving of himself hydraulic efficiency gear, satisfies behind the lifting radius locked.Arm 3 and luffing brace 4 are connected in one through steel cable; Luffing brace 4 is connected through luffing rope group with the side supports 5 of body of the tower rear side, and the assembly pulley that luffing rope is walked around on the side supports 5 of luffing brace 4, body of the tower rear side successively is connected with winch 10 on the turn table 7.Winch 10 carries out tractive through luffing rope group to luffing brace 4, and then realizes arm 3 luffings.
because body of the tower 2 has adopted box telescopic boom with arm 3, so body of the tower height and length of boom can be realized stepless variation, and then the variation of realization hoisting height and swinging radius.
have certain intensity and stability because body of the tower 2 and arm 3 in telescopic process, remain embedded lap 15 as shown in Figure 5 so guaranteed body of the tower 2 or arm 3 after elongation.
After the stretching, extension of body of the tower 2 and arm 3 was accomplished in
, suspension hook 18 linked to each other with winch 10 through rigging 17 and corresponding assembly pulley.Under the driving of engine installation 11, realize the up-down of suspension hook 18 object to be carrieds.Because body of the tower 2 is fixed on the turn table 7,, enlarge effectively lifting working area so can realize 360 ° of revolutions along with turn table 7.The rotation of turn table 7 is realized by hydraulic efficiency pressure system.
when transition, as shown in Figure 8, at first shrink arm 3, and down auxiliary at rigging 17, rotate certain angle around hinge, its integral central line is tending towards or parallel afterwards locked nearly with the integral central line of body of the tower 2.Shrink body of the tower 2 to end position, drag-line 8 pulling force are removed thereupon; Remove hinged on body of the tower 2 bottoms and the turn table 7 then; Like Fig. 7 and shown in Figure 9; Make body of the tower 2 and go up all devices to push away that an effect of drawing is slowly tilted down and move towards the fore-and-aft direction on walking chassis 1 at one of hydraulic actuating cylinder 13, locked when body of the tower 2 integral central lines are tending towards or are parallel with the chassis 1 of walking nearly.At this moment, remove the last hinge 14 of the side supports 5 of the down hinge 19 as shown in Figure 6 in the side supports 5 of body of the tower 2 rear sides and the body of the tower left and right sides, the side supports 5 that makes body of the tower 2 rear sides rotates up to the limit with locked around the hinge of self retention; Make the side supports 5 of body of the tower 2 left and right sides locked after the root direction of body of the tower 2 rotates to the limit around the hinge of himself retaining, this moment, the state of car load was shown in figure 10.Body of the tower 2 and go up all devices and lie in getting on the bus on 6 of walking chassis 1 and fixing, state is shown in figure 11, waits for the special show operation at last.The above receives tower process, and when body of the tower 2 turned forward, whole body of the tower 2 and last all devices integral body under the thrust of hydraulic actuating cylinder 13 thereof moved backward; Guarantee that its center-of-gravity position is in mobile status straight down all the time in receiving the tower process, improved the stability of receiving the tower process.
are because in entire job and transition moving process; The stretching, extension of box telescopic boom can realize automatic guidance with contraction; Need not the workman and carry out high-altitude dismounting operation; And realized the stepless variation of body of the tower height and length of boom, improved degree of automation, improved lifting efficient.
the above for but be not limited to embodiments of the invention, all increases on the basis of this embodiment, minimizing, conversion implementation step sequential scheduling all will be regarded as distorting or plagiarizing of the present invention.Structurally, only one of them adopts box slip joint with arm 3 for body of the tower 2, or any one also is included in the claim of the present invention for the box slip joint of part etc. in body of the tower 2 and the arm 3, protected by the present invention
