Abstract
The invention discloses a kind of land leveller back axle tandem-driving bogie locking mechanism, including Rear frame (2) and tandem-driving bogie (3), Rear frame (2) is positioned at tandem-driving bogie (3) top, also include connecting rod (1), the two ends of described connecting rod (1) are connected to Rear frame (2) and tandem-driving bogie (3), wherein one end is for being rotatably connected, and the other end is for removably connecting.Provide the benefit that when certain under-inflation or breakage on land leveller, by link lever locking tandem-driving bogie, tandem-driving bogie is no longer swung around back axle central shaft, make this tire not in contact with the ground, ensure that land leveller continues in the case of three-wheel is intact in trailing wheel to travel to enter maintenance station and keep in repair, thus reach to use manpower and material resources sparingly, the purpose of rapid-maintenance.
Description
Technical field
The present invention relates to a kind of land leveller back axle tandem-driving bogie locking mechanism, particularly relate to a kind of a kind of locking mechanism being arranged between land leveller tandem-driving bogie and flat Rear frame.
Background technology
Due to the particularity of land leveller work, in work progress, its back axle tandem-driving bogie needs to swing certain angle around back axle central shaft, to ensure that four wheels keeps contacting with ground the most all the time below；When a certain under-inflation of land leveller trailing wheel or blowing out suddenly, will result in land leveller cannot walk, and land leveller Active workings is general all away from maintenance place, lack special tool for service, running into the method that this problem typically uses is to look for special messenger to be unloaded by breakage wheel, and looks for special train sent for maintenance place to keep in repair, and this mode wastes time and energy, construction speed can be affected, thus cause the user is lost.
Summary of the invention
The problem existed for above-mentioned prior art, the present invention provides a kind of land leveller back axle tandem-driving bogie locking mechanism, for land leveller rear tyre because air pressure is not enough or breakage causes the situation that land leveller cannot walk, it is provided that a kind of can make the locking mechanism of walking under land leveller back axle three-wheel state.
To achieve these goals, the technical solution used in the present invention is: a kind of land leveller back axle tandem-driving bogie locking mechanism, including Rear frame and tandem-driving bogie, Rear frame is positioned at above tandem-driving bogie, also include connecting rod, the two ends of described connecting rod are connected to Rear frame and tandem-driving bogie, 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 frame, and lower end is removably connected to tandem-driving bogie.
Being welded with bearing pin in described Rear frame, small end is fed through bearing pin, and is fixed by pad and bolt.
Described connecting rod lower end and tandem-driving bogie are worn fixing by steady pin and split pin.
The present invention is in use, when certain under-inflation or breakage on land leveller, by link lever locking tandem-driving bogie, tandem-driving bogie is no longer swung around back axle central shaft, make this tire not in contact with the ground, ensure that land leveller continues in the case of three-wheel is intact in trailing wheel to travel to enter maintenance station and keep in repair, thus reach to use manpower and material resources sparingly, the purpose of rapid-maintenance.

Fig. 2 is the left view of the present invention；
In figure: 1, connecting rod, 2, Rear frame, 3, tandem-driving bogie, 4, bearing pin, 5, pad, 6, bolt, 7, steady pin, 8, split pin, 9, back axle central shaft.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2: the present invention includes Rear frame 2 and tandem-driving bogie 3, Rear frame 2 is positioned at above tandem-driving bogie 3, also includes that connecting rod 1, the two ends of described connecting rod 1 are connected to Rear frame 2 and tandem-driving bogie 3, and wherein one end is for being rotatably connected, and the other end is for removably connecting.
The present invention can use the upper end of connecting rod 1 to be removably connected to Rear frame 2, lower end is rotatably connected in the mode of tandem-driving bogie 3, but the upper end using connecting rod 1 is rotationally connected with Rear frame 2, it is the easiest that lower end is removably connected to installation and removal during operation during tandem-driving bogie 3 this mode.
Being welded with bearing pin 4 in described Rear frame 2, connecting rod 1 upper end is fed through bearing pin 4, and is fixed by pad 5 and bolt 6, uses which to connect simplicity, and can be adjusted the fixing degree of tightness of connecting rod 1 by swivel bolt 6, facilitates the rotation of connecting rod 1.
Connecting rod 1 lower end can be in the way of using bolt fixing with tandem-driving bogie 3, it would however also be possible to employ being worn fixing by steady pin 7 and split pin 8, with steady pin 7, the mode of connecting rod 1, good fixing effect are fixed in split pin 8, dismantle the most more convenient.
When rear tyre normally uses, connecting rod 1 is fixed in Rear frame 3, connecting rod 1 upper end begins to be fixed by bolt 6, when rear tyre breaks down, swivel link 1, is fixed on tandem-driving bogie 3 by its lower end by steady pin 7 and split pin 8, the upper end of connecting rod 1, lower end and back axle central shaft 9 is made to form fixing triangle joint structure, tandem-driving bogie 3 no longer swings around back axle central shaft 9, and out of order tire does not contacts with ground, and other three-wheels contact ground continues to travel the maintenance of entrance maintenance station.This locking mechanism is each side installed a set of in Rear frame 3, all can ensure the normal traveling of land leveller in the case of a certain rear tyre breakage occurs in either side.
Claims (3)
