Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is as the effect of the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part and operating principle, manufacturing process and operation using method etc., be described in further detail, have more complete, accurate and deep understanding to help those skilled in the art to inventive concept of the present invention, technical scheme.
A kind of medium-sized excavator dozer of the present utility model, comprises dozer body 8, dozer arm 4, oil cylinder 3 and lower vehicle frame 6.Lower vehicle frame 6 is provided with the second lug 10 and the 3rd lug 11.
In Fig. 1, the both sides of dozer body 8 are provided with gripper shoe 1, dozer arm 4 is arranged on dozer body 8, in order to improve the efficiency of the conduction of power between dozer arm 4 and dozer body 8, ensure the stable of the corner dimension between dozer body 8 and dozer arm 4, the connected mode of dozer arm 4 and dozer body 8 is for being fixedly connected with mode.Dozer arm 4 is connected with the bottom of lower vehicle frame 6 away from one end of dozer body 8, because dozer arm 4 to need around lower vehicle frame 6 at vertical rotation in surface to ensure that dozer arm 4 can be packed up and put down, therefore the connected mode of dozer arm 4 and lower vehicle frame 6 is for being flexibly connected.Pack up for dozer arm 4 and dozer body 8 and be connected dozer body 8 with the one end of putting down the oil cylinder 3 providing driving force, the other end of oil cylinder 3 connects lower vehicle frame 6, oil cylinder 3 and lower vehicle frame 6 junction are higher than the junction of dozer arm 4 and lower vehicle frame 6, because dozer body 8 and dozer arm 4 have the action packed up and put down, therefore oil cylinder 3 is active link with the connected mode of dozer body 8 and lower vehicle frame 6.
Pack up for dozer arm 4 and dozer body 8 and be connected lower vehicle frame 6 with the one end of putting down the oil cylinder 3 providing driving force, the other end can also connect dozer arm 4.
In Fig. 1, oil cylinder 3 comprises oil cylinder body and cylinder putter, oil cylinder body is the cup-like structure that one end open one end is closed, one end of oil cylinder body openings is connected with one end of cylinder putter, the axis of oil cylinder body and the axis being parallel of cylinder putter, oil cylinder body and cylinder putter can move along respective axis, oil cylinder body and cylinder putter keep in touch, cylinder putter one end is in oil cylinder body interior, the other end of cylinder putter stretches out from one end of the opening of oil cylinder body, the outside of one end that oil cylinder body is closed is provided with the 5th installing hole, the end of one end that cylinder putter stretches out from oil cylinder body is provided with the 6th installing hole.Oil cylinder 3 is to provide the power source that dozer arm 4 can be packed up and put down, ensure that oil cylinder 3 provides the most reliable of power to dozer arm 4, the power that when dozer arm 4 is packed up and put down, oil cylinder 3 provides is minimum, will ensure that the angle between oil cylinder 3 and dozer arm 4 is right angle, when dozer body 8 plays a supportive role, oil cylinder 3 is in the state of locking, oil cylinder 3 prevents dozer body 8 from receiving role, according to lever principle, when the tie point of oil cylinder 3 and dozer body 8 is more away from the contact point of dozer arm 4 with lower vehicle frame 6, the power provided required for oil cylinder 3 is less, the contact point of the tie point of oil cylinder 3 and dozer body 8 and dozer arm 4 and lower vehicle frame 6 from the near to the remote time, oil cylinder 3 is descending with the angle of dozer arm 4, therefore oil cylinder 3 keeps 10 to 30 to spend with the angle of dozer arm 4, be more conducive to the action that dozer body 8 is packed up and put down, serve smooth dozing and support, the effect of fixing excavator and the raising excavator speed of travel.
In order to ensure that dozer body 8 to be packed up and putting down in process continuously mild, the length after oil cylinder 3 shrinks is greater than the length of dozer arm 4.
Dozer body 8 is provided with the first lug 9, first lug 9 and is provided with the first installing hole, and the first installing hole is connected with the 5th installing hole on oil cylinder 3 by bearing pin 2, and after connecting, the first lug 9 and oil cylinder 3 can rotate around bearing pin 2.
Lower vehicle frame 6 is respectively equipped with the second lug 10 and the 3rd lug 11, second lug 10 and the 3rd lug 11 are respectively equipped with the 3rd installing hole and the 4th installing hole, the horizontal plane at the central axis place of the 3rd installing hole is on the top of the horizontal plane at the central axis place of the 4th installing hole, and namely the 3rd installing hole is higher than the 4th installing hole.
The 6th installing hole on oil cylinder 3 is connected with the 3rd installing hole on the second lug 10 on lower vehicle frame 6 by bearing pin 5, and after connecting, lower vehicle frame 6 and oil cylinder 3 can rotate around bearing pin 5.
The second installing hole on dozer arm 4 on dozer body 8 is connected with the 4th installing hole on the 3rd lug 11 on lower vehicle frame 6 by bearing pin 7, and after connecting, lower vehicle frame 6 and dozer arm 4 can rotate around bearing pin 7.
By shortening and the elongation of oil cylinder 3, realize dozer and up pack up and down operation acts; Realize smooth dozing and support, fix excavator effect.
In order to strengthen the intensity of dozer body 8, the junction of dozer body 8 and dozer arm 4 is provided with floor.
The bottom end face of dozer body 8 is parallel with top end face, medium-sized excavator dozer can also do the effect supported, because medium-sized excavator is from great, in order to increase the contact area of medium-sized excavator dozer and ground, reduce the pressure between medium-sized excavator dozer and ground, improve reliability when medium-sized excavator dozer supports, the area of the area ratio top end face of the bottom end face of dozer body 8 is large, is respectively provided with a gripper shoe 1 at the two ends of dozer body 8.
The connected mode of gripper shoe 1 and dozer body 8 for being fixedly connected with, as welding, riveted joint, monoblock cast.In order to ensure that the level and smooth of the junction of gripper shoe 1 and dozer body 8 and the stress reduced between gripper shoe 1 and dozer body 8 are concentrated, increase the intensity of junction, the junction of gripper shoe 1 and dozer body 8 is provided with the reinforcing rib of arc-shaped.
Operating efficiency during in order to improve medium-sized excavator dozer leveling operation further and the contact area on dozer body 8 and ground when supporting operation, the shape of the horizontal section of dozer body 8 is set to triangle, leg-of-mutton longest edge is than leg-of-mutton maximum angular with close lower vehicle frame 6, and namely leg-of-mutton maximum angular and lower vehicle frame 6 are respectively on the both sides of leg-of-mutton longest edge.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
