Equipment technical field.
Background technique
Understand according to utility model people, in engineering fields such as water conservancy, traffic, buildings, needs to build under different geological conditions
The various continuous walls in underground.In the actual construction process, to contain gravel, boulder, the stratum of the stone that floats and harder
Deep trouth is opened on rock stratum and builds the continuous wall in various undergrounds, then is very intractable and problem to be solved.Existing bull is drilled to
Scouring machine, driving mechanism is more drill bits rotating-milling under ballast, and excavation speed is fast, and mechanization degree is high, but equipment volume is certainly
Great and do not have percussion, the driving of main suitable soil layer is not suitable for cobble, erratic boulder stratum, can not be used for basement rock
Driving.
Chinese utility model and utility model patent (patent No. ZL filed in utility model people on April 10th, 2017
2017 20371264.7), disclose a kind of horizontal uniaxial orientation repercussion combined type engineering groover, the technical side of the patent
Case discloses a kind of horizontal uniaxial orientation revolution-impact combination driving formula engineering groover, including has hoisting equipment and power
The running gear and monitoring device of system;Hoisting equipment traction end is hung with impact milling attachment, and impact milling attachment includes
Vertical guide frame, deviation correcting device, milling axis and percussion mechanism with milling cutter;The axis of milling axis is located at guiding
In plane locating for frame, and horizontally or diagonally arrange;Milling axis is led to by the hydraulic motor driving of accumbency or vertical hydraulic motor
Reversing arrangement driving is crossed, the directional rotating milling state that there is milling axis partition balancing to reversely rotate, percussion mechanism, which is placed in, leads
Into frame;The lower section that connection crossbeam between step-cut milling axis is mounted on guide frame bottom beam by suspending carriage in midair, punching
The drill steel for hitting device is impacted under hydraulic-driven in connection crossbeam and milling axis and positioning drill bit.On the one hand the structure uses milling
Mode axis segmentation and reversely rotated balances milling counter-force, avoids excavator attitude drift;On the other hand, in guide frame
Bottom beam below add connection crossbeam, by include milling axis, positioning drill bit including excavator be fixed on contact crossbeam on, make
Jump bit is transmitted without guide frame, but directly impacts connection crossbeam by drill steel, is improved excavator and is rushed to ground
Acceleration is hit, the effect of fractured rock is improved, the impact for reducing jump bit on guide frame and wherein equipment influences.
It is segmented the scheme for reversely rotating balance above by milling axis, realizes directional-rotation balance milling counter-force, makes to grasp
Make more stable, fixed rotating-milling direction, ensure that milling cutter have ready conditions for cutting direction selection possible angle with
Shape reduces cutter tooth abrasion to greatly improve drivage efficiency;Excavator (including connection crossbeam, milling axis and positioning drill bit)
It slides mounting in vertical direction with bottom beam, the drill steel of percussion mechanism is made directly to impact the connection crossbeam in excavator, without
It is direct impact on the bottom beam of guide frame, substantially reduces the weight for the body that is directly hit in this way, to improves digging dress

Cost;Replace the accessories higher cost such as bearing in construction, trunnion axis has more advantage in the driving of native horsestone and gravel layer, but to removing
Antiseepage is thick to slot except requiring, flute profile is relatively higher without the engineer application field cost strictly limited.
In addition, once engineering groover was rushed in a kind of suspension type convolution shake of utility model to the utility model people originally declared in the past
(patent No. 201410326904.3), " each transmission shaft passes through shake block stamp, and the shake block stamp is along each transmission shaft in technical solution
Vertical movement " and " shake block stamp, which rises, falls within or is placed in frame positioning beam upper end ", because laterally shake block stamp is distributed in entire frame
Bottom beam upper surface.The transmission shaft of multiple drill bits passes through a whole shake block stamp, such shake block stamp performance difficulty, if by its point
Section then is difficult to accomplish synchronous impact for each section again, respectively asynchronous to impact then disperses force, and causes to swing.Block stamp impact is shaken in frame
Frame, wherein equipment bears greater impact, while the weight that is hit is big, and the acceleration and detritus efficiency to rock impact are by shadow
It rings.
