Abstract
The utility model discloses a locking mechanism for an equilibrium box for a rear axle of a land leveler. The locking mechanism comprises a rear frame (2) and the equilibrium box (3), wherein the rear frame (2) is located above the equilibrium box (3). The locking mechanism also comprises a connecting rod (1). Both ends of the connecting rod (1) are respectively connected with the rear frame (2) and the equilibrium box (3), wherein one end of the connecting rod (1) is rotatably connected, and the other end of the connecting rod (1) is detachably connected. The locking mechanism has the beneficial effects that when a certain tire of the land leveler is insufficient in air pressure or damaged, the equilibrium box is locked through the connecting rod, so that the equilibrium box does not swing around the center shaft of a rear axle any longer, and the tire is not contacted with the ground, so that the land leveler continues to run to enter a maintenance station for maintenance under the condition that three rear wheels are undamaged, and therefore, the goals that manpower and material resources are saved, and rapid maintenance is performed are achieved.
Description
Technical field
The utility model relates to a kind of land leveller back axle tandem-driving bogie locking mechanism, relates in particular to a kind of a kind of locking mechanism being arranged between land leveller tandem-driving bogie and flat rear vehicle frame.
Background technology
Due to the particularity of land leveller work, in work progress, its back axle tandem-driving bogie need to swing certain angle around back axle central axis, to guarantee that four wheels all keeps in touch with ground all the time below; When a certain under-inflation of land leveller trailing wheel or while blowing out suddenly, will cause land leveller to walk, and land leveller Active workings is generally all away from maintenance place, lack special tool for service, running into the general method adopting of this problem is to look for special messenger that damaged wheel is unloaded, and looks for the maintenance of special train sent for maintenance place, and this mode wastes time and energy, can affect construction speed, thereby cause damage to user.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of land leveller back axle tandem-driving bogie locking mechanism, because air pressure is not enough or the damaged situation that causes land leveller to walk, provide a kind of locking mechanism of walking under land leveller back axle three-wheel state of can making for land leveller rear tyre.
To achieve these goals, the technical solution adopted in the utility model is: a kind of land leveller back axle tandem-driving bogie locking mechanism, comprise rear vehicle frame peace weighing apparatus case, rear car chord position is in tandem-driving bogie top, also comprise connecting rod, the two ends of described connecting rod are connected to rear vehicle frame peace weighing apparatus case, and wherein one end is for being rotatably connected, and the other end is for removably connecting.
The upper end of connecting rod is rotationally connected with rear vehicle frame, and lower end is removably connected to tandem-driving bogie.
On described rear vehicle frame, be welded with bearing pin, small end wore bearing pin, and fixed by pad and bolt.
Described connecting rod lower end and tandem-driving bogie wear fixing by steady pin and cottor pin.
The utility model in use, in the time of certain under-inflation on land leveller or breakage, by link lever locking tandem-driving bogie, tandem-driving bogie is no longer swung around back axle central axis, make this tire not in contact with the ground, guaranteeing that land leveller continues to travel the in the situation that three-wheel being intact in trailing wheel enters maintenance station and keeps in repair, use manpower and material resources sparingly thereby reach, and the object of rapid-maintenance.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is left view of the present utility model;
In figure: 1, connecting rod, 2, rear vehicle frame, 3, tandem-driving bogie, 4, bearing pin, 5, pad, 6, bolt, 7, steady pin, 8, cottor pin, 9, back axle central axis.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2: the utility model comprises rear vehicle frame 2 and tandem-driving bogie 3, rear vehicle frame 2 is positioned at tandem-driving bogie 3 tops, also comprises connecting rod 1, and the two ends of described connecting rod 1 are connected to rear vehicle frame 2 and tandem-driving bogie 3, wherein one end is for being rotatably connected, and the other end is for removably connecting.
The utility model can adopt the upper end of connecting rod 1 to be removably connected to rear vehicle frame 2, lower end is rotatably connected in the mode of tandem-driving bogie 3, but adopt the upper end of connecting rod 1 to be rotationally connected with rear vehicle frame 2, when lower end operates while being removably connected to tandem-driving bogie 3 this mode, installation and removal are all easier.
On described rear vehicle frame 2, be welded with bearing pin 4, connecting rod 1 upper end wore bearing pin 4, and fixing by pad 5 and bolt 6, adopted which to connect easy, and can regulate the fixing degree of tightness of connecting rod 1 by swivel bolt 6, facilitated the rotation of connecting rod 1.
Connecting rod 1 lower end and tandem-driving bogie 3 can adopt the fixing mode of bolt, also can adopt to be worn fixingly by steady pin 7 and cottor pin 8, are coordinated the mode of cottor pin 8 stationary links 1 by steady pin 7, and good fixing effect, dismantles also more convenient.
When rear tyre normally uses, connecting rod 1 is fixed on rear vehicle frame 3, connecting rod 1 upper end begins to be fixed by bolt 6, in the time that rear tyre breaks down, rotation connecting rod 1, is fixed on tandem-driving bogie 3 by its lower end by steady pin 7 and cottor pin 8, make upper end, lower end and the back axle central axis 9 of connecting rod 1 form fixing triangle joint structure, tandem-driving bogie 3 no longer swings around back axle central axis 9, and out of order tire does not contact with ground, and other three-wheel kiss the earths continue to travel and enter maintenance station maintenance.This locking mechanism is each side installed a set of on rear vehicle frame 3, under the situation of a certain rear tyre breakage appears in either side, all can guarantee normally travelling of land leveller.
