Description
Technical field
The utility model relates to a kind of drg of transfer crane wheel.
Background technology
The Chinese utility model patent that existing a kind of patent No. is a CN91201335.4 title " for motor vehicle axle braking device " discloses a kind of structure, and its keystone configuration is two axle bumpers about be equipped with respectively at the two ends of axletree.Left side axle bumper is processed with a camming surface, between camming surface and the brake hubs rolling body is housed.Right axle bumper one end is processed with tooth, in the groove of axle bowl tooth ingear ratchet therewith is housed.The Decorative drum two ends are connected with brake hubs with the axle bowl respectively.This device can be used for bicycle or other vehicle.Flywheel drives right axle bumper when rotating, the ratchet engagement by on tooth on the right axle bumper and the axle bowl is advanced wheel.Glancing impact, the pinching handgrip, the retainer of rolling body drives rolling body and rotates together, produces friction force and squeese pressure between rolling body and brake hubs, makes wheel decelerates or stops.This structure often is applicable to M/C, and is not suitable for rail vehicle, especially is not suitable for crane locomotive, and because of its back brake of stopping needs stability, and above-mentioned structural drag is also big inadequately, slides easily when the lift heavy thing, so structure also needs further to improve.
Summary of the invention
Technical problem to be solved in the utility model is the drg that a kind of reasonable in design, transfer crane wheel that braking brake is effective and easy to use is provided at above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the drg of this transfer crane wheel, include the oil cylinder of hydraulically extensible axle, it is characterized in that: described hydraulically extensible axle one side is provided with brake, this brake includes the expansion link of housing and horizontally set, but and described expansion link sway be arranged in the housing, and an end of expansion link contacts mutually with hydraulically extensible axle one end, and the other end of expansion link can contact with the wheel corresponding circle side face of crane trolley when it stretches directly or indirectly mutually, and the bottom of oil cylinder and brake is fixed on the crane trolley parts.
As improvement, its left side of described expansion link contacts together mutually by the right side of steel ball and hydraulically extensible axle, rubs between expansion link and the hydraulically extensible axle contact surface reducing, to reach the purpose of better protection oil cylinder.
As improvement, the structure optimization that the other end of described expansion link can contact mutually with the wheel corresponding circle side face of crane trolley when it stretches is: the other end of expansion link can contact indirectly mutually by brake scotch and wheel corresponding circle side face, and the other end of this expansion link is fixed with each other by pivot pin and brake scotch.With further raising braking effect.
Improve again, but described expansion link sway the structure that is arranged in the housing may be selected to be: its periphery of described expansion link is equipped with returning spring, one end of this returning spring contacts mutually with the step surface of expansion link one end, and the other end of returning spring contacts together mutually with the annular wall of housing one end, thereby it is more flexible, more practical that expansion link is used.
Improve, described oil cylinder one end extends orienting sleeve again, described hydraulically extensible axle can about telescopically place orienting sleeve, reach the hydraulically extensible axle and on design-calculated path of motion, move around exactly.
Improve, described oil cylinder can be together supporting with the oil pump power pack that is fixed on the crane trolley again.
Compared with prior art, the utility model adopts hydraulically extensible axle one side to be provided with brake, this brake includes the expansion link of housing and horizontally set, but and described expansion link sway be arranged in the housing, and an end of expansion link contacts mutually with hydraulically extensible axle one end, and the other end of expansion link can contact mutually with the wheel corresponding circle side face of crane trolley when it stretches, and the bottom of oil cylinder and brake fixedly is fixed on the crane trolley part.The design's advantage is that the braking point is arranged on the wheel circumference limit of crane trolley, thereby strengthened the moment of brake effectively, increased substantially the braking force of brake, thereby reach better braking effect, and, as long as by hydraulic oil cylinder driving, making things convenient for again so use flexibly during use, is a kind of very practical structure.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is along the cutaway view of A-A line among Fig. 1.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2; the drg of the transfer crane wheel of present embodiment; include the oil cylinder 1 of hydraulically extensible axle 11; described hydraulically extensible axle 11 1 sides are provided with brake 2; this brake 2 includes the expansion link 21 of housing 24 and horizontally set; but and above-mentioned expansion link 21 sway be arranged in the housing 24; and an end of expansion link 21 contacts mutually with hydraulically extensible axle 11 1 ends; and these expansion link 21 left sides are to contact mutually together by the right side of steel ball 12 with hydraulically extensible axle 11, to reach the purpose of better protection oil cylinder.And the other end of expansion link 21 can contact with the wheel 3 corresponding circle side faces of crane trolley 5 when it stretches directly or indirectly mutually, the other end of present embodiment expansion link 21 is to contact mutually with wheel 3 corresponding circle side faces by brake scotch 4, that is, the other end of expansion link 21 is fixed with each other by pivot pin 21a and brake scotch 4.Improve braking effect to increase area of contact.Periphery at expansion link 21 is equipped with returning spring 23, and an end of this returning spring 23 contacts mutually with the step surface 211 of expansion link 21 1 ends, and the other end of returning spring 23 contacts together mutually with the annular wall 22 of housing 24 1 ends.Oil cylinder 1 is fixed on the transverse slat 7 with the bottom of brake 2, and an end of transverse slat 7 is fixed on the crane trolley 5, sees shown in Figure 1.In order to move up and down in the track that hydraulically extensible axle 11 is set in oil cylinder 1 exactly, above-mentioned oil cylinder 1 one end extends orienting sleeve 10, hydraulically extensible axle 11 can about telescopically place orienting sleeve 10.The oil cylinder 1 of present embodiment and supporting the linking together of oil pump power pack of being fixed on the crane trolley 5, but do not draw in the oil pump power picture group.
This device,
Cylinder diameter φ 100
Oil pressure Pmax=15MPa
Pmin＝10MPa
Braking force 7500kg/11400kg
Lock torque braking force * radius of wheel * friction coefficient (0.35-0.4)
Oil cylinder piston stroke 5mm
Principle of work of the present utility model is:
When crane trolley during in normal operation, move back and forth in orbit with crane trolley, when brake, can open oil cylinder, make the axially right stretching, extension of hydraulically extensible, the promotion expansion link moves right, until expansion link through the brake scotch overhead on wheel, crane trolley is fixed on the track, thereby plays braking action crane trolley, and when the crane trolley needs are mobile, axially move left as long as unclamp hydraulically extensible, because the effect of returning spring, the boom that contracts automatically replies original state, not only safe effect is good, and uses very convenient.
