The specific embodiment
Below in conjunction with accompanying drawing preferred implementation of the present utility model is elaborated.
With reference to shown in Figure 1, be the front view of the utility model fixed column type boom crane.As seen from Figure 1, the utility model fixed column type boom crane comprises column 101, ring rail 401, cantilever, swing type mechanism 106 and at least one group of mechanism 103 that changes one's profession, cantilever is made of pivoted arm 102 and the hold-down arm 104 that is connected in pivoted arm 102 bottoms, pivoted arm 102 is connected with column 101 by swing type mechanism 106, this at least one group mechanism 103 that changes one's profession is arranged at hold-down arm 104 bottoms, and contacts with ring rail 401 on being arranged at described column 101.This at least one group mechanism 103 that changes one's profession comprises reducing motor 405, transmission gear 403 and steps on wheels that reducing motor 405 drives the described wheels of stepping on by transmission gear 403 and rotates along ring rail 401.
With reference to Fig. 2 and shown in Figure 3, be respectively A-A and B-B section-drawing among Fig. 1 and Fig. 2.Find out further that by above-mentioned accompanying drawing in this preferred embodiment, this at least one group mechanism 103 that changes one's profession comprises two groups, step on wheels for two of these two groups of mechanisms that change one's profession and be arranged side by side, be connected with hold-down arm 104 separately by bearing pin 404.Step on wheels and hold-down arm 104 preferred connection modes are hinged for these two, adjust function, make tread and ring rail 401 keep closed contacts, improve load-carrying capacity to realize servo-actuated adjustment and self adaptation centering.
And above-mentioned each stepped on wheels and included two of being symmetricly set in transmission gear 403 both sides and step on wheel 402, and transmission gear 403 is stepped on wheel 402 engagements and driven these two and step on wheel 402 along 401 rotations of ring rails with two.
With reference to shown in Figure 4, be the partial enlarged drawing of the utility model fixed column type boom crane swing type mechanism of marking with circle among Fig. 1.As can be seen from this figure, this swing type mechanism comprises mandrel 201, self-aligning roller bearing 202 and bearing seat 204, mandrel 201 tops are connected with pivoted arm 102, and bearing seat can be connected with column 101 by the mode of welding, and mandrel 201 passes self-aligning roller bearing 202 and is placed in the bearing seat 204.This swing type mechanism also comprises the self-aligning thrust roller bearing of being located between self-aligning roller bearing 202 and the bearing seat 204 203, and mandrel 201 also will pass self-aligning thrust roller bearing 203 before passing self-aligning roller bearing 202 and placing in the bearing seat 204 like this.Self-aligning roller bearing 202 and self-aligning thrust roller bearing 203 all possess the aligning function.
Be further detailed below in conjunction with the principle of work of concrete working process to the utility model fixed column type boom crane: when this fixed column type boom crane need rotate at the object of slinging, reducing motor 405 drove by transmission gear 403 and steps on wheels along 401 rotations of ring rail.Step on the rotation drive cantilever rotation of wheel along ring rail 401, this moment, mandrel 201 cooperated with the inner ring of self-aligning roller bearing 202 and self-aligning thrust roller bearing 203, the outer ring of self-aligning roller bearing 202 and self-aligning thrust roller bearing 203 cooperates with bearing seat 204, and mandrel 201 is connected by bolt with flange with pivoted arm 102 has realized that pivoted arm 102 can 360 ° of rotations.Wherein, self-aligning roller bearing 202 main bearing radial forces, self-aligning thrust roller bearing 203 mainly bears axial force, and possesses the aligning function respectively.Two of this two groups of mechanisms that change one's profession step on wheels owing to be arranged side by side, and separately and hold-down arm 104 be hinged.Thereby can realize self adaptation centering adjustment function, and make tread and encircle rail 401 closed contact constantly, improve load-carrying capacity.Another works on simultaneously also can to guarantee to be out of order constantly by a motor, thereby guarantees that activity in production is unaffected.
Need to prove at last; the above only is preferred embodiment of the present utility model; rather than to the qualification of technical solutions of the utility model, any the utility model technical characterictic being equal to of being done replaced or corresponding improvement, still within protection domain of the present utility model.
