Engineering driller belongs to medial and small construction machinery, is mainly used in skyscraper, harbour, harbour, dam, electric power, bridge
Etc. the construction of the large-diameter bored pile of engineering, it is desirable to which speed of application is fast, construction hole position is accurate, but in use because of external rings
Border it is complicated various, construction Uneven road be very common phenomenon, it is therefore desirable to the deflection angle of engineering driller is wider, uses model
Enclose bigger.
The content of the invention
The purpose of this utility model was used to solve the change in the engineering driller course of work due to construction environment
The problem of accuracy is bad in journey plays tower carriage assembly there is provided variable bit a kind of simple in construction, compact to design.
The utility model is adopted the following technical scheme that：A kind of variable bit plays tower carriage assembly, including sliding rack body component, a tower
Oil cylinder, swivel head, beat oil cylinder, tower bearing, the first fixed pin shaft, the second fixed pin shaft and the 3rd fixed pin shaft, the cunning
One end of frame portions is with playing the connection that tower bearing is relatively rotated, and the lower end of the sliding rack body component is provided with beat oil cylinder and rotation
Rotary head, one end of the swivel head is connected on sliding rack body component by the 3rd fixed pin shaft, the other end point of the swivel head
Left pin shaft hole and right pin shaft hole are not provided with, and second fixed pin shaft can be arranged in left pin shaft hole or right pin shaft hole and realize
The flexible connection of swivel head and beat oil cylinder, one end of the piston rod of the beat oil cylinder is fixed on cunning by the first fixed pin shaft
On frame portions, the bottom of described tower oil cylinder has been fixed on tower bearing by playing a tower cylinder support, described tower oil cylinder
What top was rotated is connected on swivel head.
Further, it is provided with end cap on the 3rd fixed pin shaft.
Further, described tower bearing is made up of horizontal segment and extension, the folder between the extension and horizontal segment
Angle is obtuse angle.
The utility model is simple in construction, compact to design, easy to use, portable construction, and deflection angle is wide, can bear high-power
Impact, wide adaptation range, it is ensured that the perpendicularity requirement and gradient requirement of construction hole position.

Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As Figure 1-Figure 5, a kind of variable bit plays tower carriage assembly, including sliding rack body component 1, tower oil cylinder 5, swivel head
4th, beat oil cylinder 3, tower bearing 2, the first fixed pin shaft 7, the second fixed pin shaft 8 and the 3rd fixed pin shaft 9.Sliding rack body component 1
One end with playing the connection that tower bearing 2 is relatively rotated, the lower end of sliding rack body component 1 is provided with beat oil cylinder 3 and swivel head 4, revolves
One end of rotary head 4 is connected on sliding rack body component 1 and further fixed by end cap 12 by the 3rd fixed pin shaft 9, rotation
First 4 other end is respectively arranged with left pin shaft hole 10 and right pin shaft hole 11, and the second fixed pin shaft 8 can be arranged on left pin shaft hole 10
Or the flexible connection of swivel head 4 and beat oil cylinder 3 is realized in right pin shaft hole 11, one end of the piston rod of beat oil cylinder 3 passes through
One fixed pin shaft 7 is fixed on sliding rack body component 1, and the bottom for playing tower oil cylinder 5 has been fixed on tower bearing by playing tower cylinder support 6
On 2, being connected on swivel head 4 for the top rotation of a tower oil cylinder 5 plays a tower bearing 2 and is made up of horizontal segment and extension, extension
Angle between horizontal segment is obtuse angle.
Method of work：When soil not usually, rig coordinates the utility model to use, by having controlled the flexible of tower oil cylinder 5
Whole device can be made to be worked in 90 ° of angular range（As shown in Figure 2）.The angle of beat as needed adjusts beat oil manually
One end of cylinder 3 is conjugated between left pin shaft hole 10 and right pin shaft hole 11, it is necessary to toward right avertence then by beat oil cylinder 3 by second
Fixed pin shaft 8 is fixed in right pin shaft hole 11（As shown in Figure 5）, it is necessary to which beat oil cylinder 3 then is passed through into the second steady pin toward left avertence
Axle 8 is fixed in left pin shaft hole 10（As shown in Figure 4）.By the flexible and left and right displacement of beat oil cylinder 3, sliding rack body can be controlled
Component 1 is arbitrarily deflected between the scope of 28 ° of left and right.Accuracy in use is greatly improved.
