Abstract
The invention relates to a travelling mechanism device, in particular to an ontrack travelling mechanism device of a track type crane. A support frame positioned on the lower end of a travelling cart is provided with a travelling wheel; the travelling cart is arranged on a track through the travelling wheel; one end of the travelling cart is provided with a travelling motor; the travelling motor is connected with a travelling speed reducing machine; an output shaft of the travelling speed reducing machine is provided with a driving gear; the driving gear is connected with a travelling wheel gear; both sides of the supporting frame are respectively provided with two movable hinged shafts; the two movable hinged shafts are connected through a balancing pole; and a front guide device is fixed on the front end of the supporting frame, and a rear guide device is fixed on the rear end of the supporting frame. The travelling mechanism can be suitable for the deformation of the track and provide stable driving force for the travelling cart, thereby enabling the travelling cart to normally move on the deformed track.
Description
Technical field
The present invention relates to a kind of traveling gear device, especially a kind of locomotive crane at rail traveling gear device.
Background technology
All to be installed in rail traveling gear device at the locomotive crane of outside work such as handling bridge, transfer crane, bucket-wheel stacker reclaimer, span winch etc.Type rail mounted high pedestal jib crane requires complete machine structure firm from great, therefore, needs very that the failure-free cart walking mechanism supports this huge body, with load-carrying capacity and the resistance to capsizing that improves its complete machine.Be the bearing capacity that the makes the cart walking mechanism wheel impartial characteristic of trying one's best.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of traveling gear device is provided, be used for walking of locomotive crane at rail.
According to technical scheme provided by the invention, a kind of traveling gear device, the bracing frame of walking cart lower end is provided with running wheel, the walking cart by the running wheel setting in orbit, one end of walking cart is provided with the walking electrical motor, the walking electrical motor is connected with driving speed reducer, and the output shaft of driving speed reducer is provided with driven wheel, and driven wheel is connected with the running wheel gear; The both sides of bracing frame are provided with two movable hinges respectively, connect by trammel beam between two movable hinges; It is one leading to device that the front end of bracing frame is fixed, and a back guide piece is fixed in the rear end of bracing frame.
Described running wheel comprises drive wheel, carrier gear and driven wheel, connects by carrier gear between described drive wheel and the driven wheel.
Advantage of the present invention is: traveling gear of the present invention can adapt to track deformation, for the walking cart stable propulsive effort is provided, make the walking cart the distortion track on can proper motion.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
As shown in the figure, the present invention includes: the lower end of walking cart is provided with running wheel, walks cart by the running wheel setting in orbit, and track is arranged on the track fine strain of millet, one end of walking cart is provided with walking electrical motor 4, and walking electrical motor 4 is connected with driving speed reducer 6; The output shaft come-up of electrical motor 4 of being expert at the walking drg 5 that is dynamically connected; The output shaft of driving speed reducer 6 is provided with driven wheel 11, the drive walking cart orbital motion thereby driven wheel 11 and running wheel cooperatively interact.Described running wheel comprises drive wheel 1, carrier gear 2 and driven wheel 3, connects by carrier gear 2 between described drive wheel 1 and the driven wheel 3.
The present invention relates to a kind of traveling gear of high pedestal jib crane.The traveling gear of high pedestal jib crane is made of four gate seat supporting leg lower end four walking carts of pivotally attached, is respectively the walking cart in left side, the walking cart on right side, each walking cart before and after each side; Each walking cart comprises drive wheel 1, carrier gear 2, driven wheel 3, walking electrical motor 4, walking drg 5, driving speed reducer 6, the front end of the bracing frame 7 of each walking cart is fixed a front bumperette 9, and a hand-held skate device 10 is fixed in the rear end of the bracing frame 7 of each walking cart.
On the bracing frame 7 of an end of walking cart, be respectively arranged with two movable hinges 8, connect by trammel beam between two movable hinges 8, its advantage is: can adapt to track deformation, for the walking cart stable propulsive effort is provided, make the walking cart the distortion track on can proper motion.
