The automatic drilling head tracking and controlling system includes one drilling bit rotation speed sensor in the driving head, one longitudinal drilling bit feeding speed sensor, and one microcomputerized automatic control system, which includes CPU, automatic controller and variable-frequency speed regulator, and is used to receive and process the signals from the two sensors and ontrol motor frequency and rotation speed.
Description
The present invention relates to a kind of helical burr ram machine with drilling lead synchronous tracking robot control system(RCS), it belongs to employed equipment in the foundation of civil work engineering.
For stake machine drill tool its helical pitch when the rotary drilling helical burr ram machine of strict demand is arranged, for example long screw cast-in-place pile machine, long screw thread preformed pile machine and other have the engineering driller of identical requirement, as long spiral engineering driller etc.In existing helical burr ram machine, owing to do not install the drilling lead synchronous tracking robot control system(RCS), thereby the stake machine is when rotary drilling, the influence that changed by formation resistance, cause its lead of screw to change, can not make high-quality long helical burr ram, and efficiency of construction is often very low.Adopting traditional mechanical proportional transmission system, though can accomplish the lead of screw stipulated, because the moment of torsion that piling machinery transmitted is very big, design and installation mechanical proportional transmission system will be a very complicated and benzene weight.For overcoming above-mentioned shortcoming, following scheme is proposed.
The objective of the invention is: a kind of helical burr ram machine with drilling lead synchronous tracking robot control system(RCS) is provided.Its control section is made up of micro computer, two tachogenerators and a variable-frequency governor.
Technical scheme of the present invention is: the helical burr ram machine with drilling lead synchronous tracking system comprises a machine body, power set and drilling tool, and hoist driving device.An overhead unit head is housed on this machine body, and it is equipped with drilling tool by more than one Motor Drive on the output shaft of this overhead unit head, is provided with the elevator transmission system at rig body and the opposed opposite side of overhead unit head; Described drilling lead synchronous tracking robot control system(RCS) is to be provided with drilling tool rotation speed sensor and drilling tool length feed velocity sensor on the overhead unit head, be provided with one in the following side of stake machine body and can receive computing and the described two sensors signal of contrast, and the auto-control system with micro-computor of adjustable motor frequency and rotating speed, this auto-control system with micro-computor comprises: micro computer central processing unit and micro computer automatic controller, and variable-frequency governor.Described drilling lead synchronous tracking robot control system(RCS) also can be used for other need keep lead of screw, particularly long spiral engineering driller or pile driver.
Advantage of the present invention is:
1. owing to adopted high accuracy drilling tool rotation speed sensor and drilling tool length feed sensor, in order to detect drilling tool rotary rotary speed and feed speed, small and exquisite being convenient to of its volume installed.
2. automatic control system adopts advanced micro processor, and the dynamic data of energy high speed processing sensor input is exported and controlled variable-frequency governor synchronously the unit head motor speed is constantly drawn close to theoretical rotational speed.
3. adopt the drilling lead synchronous tracking robot control system(RCS), can optimize the structure of this Class pile driver greatly, omitted the heavy mechanical proportional transmission device of complexity and benzene, adopt frequency control can also reduce power consumption simultaneously.
Also in conjunction with the accompanying drawings the present invention is elaborated with regard to an example below:
Fig. 1. be the structural representation of helical burr ram machine of the present invention
Fig. 2. be the side schematic view of Fig. 1
Fig. 3. be auto-control system with micro-computor block diagram of the present invention
As depicted in figs. 1 and 2, have the helical burr ram machine of drilling lead synchronous tracking robot control system(RCS), an overhead unit head 2 is housed on the body 1 of stake machine.Unit head 2 is driven by more than one motor 3, and drilling tool 4 is housed on the output shaft of unit head 2.Creeping into or promoting of overhead unit head 2 and drilling tool 4 is to be handled by elevator transmission system 5.When the helical burr ram machine bored down or promotes, motor 3 drove overhead unit head 2 and drilling tool 4 rotations, and unit head 2 and drilling tool 4 are put down or promoted to elevator transmission system 5 simultaneously, makes the drilling tool swivel feeding; Simultaneously, on the transmission axle of unit head 2, be provided with one in order to detect the drilling tool rotation speed sensor 6 of drilling tool rotary rotary speed, also be provided with one in order to detect the drilling tool length feed velocity sensor 7 of drilling tool vertical feed speed on unit head 2, two kinds of instantaneous velocity signals that these two sensors collect tracking respectively constantly import auto-control system with micro-computor 8 into.Forming screw cast-in-place pile 9 in the place of having constructed, is undisturbed soil 10 in the place of not construction.
As shown in Figure 3, after the instantaneous velocity signal of telecommunication of drilling tool rotation speed sensor 6 and length feed velocity sensor 7 enters micro computer central processing unit 8A in the auto-control system with micro-computor 8, the process computing is also compared its error, draw the theoretical rotational speed of this instantaneous motor 3, again through micro computer automatic controller 8B and variable-frequency governor 8C, the frequency of supply of synchronous change motor 3 is constantly revised motor 3 rotating speeds.The drilling tool of helical burr ram machine can accurately be moved by the standard pitch of setting in whole drilling process.
Described drilling lead synchronous tracking robot control system(RCS) can also be used for engineering driller or pile driver that needs keep lead of screw, for example, and long spiral engineering driller or pile driver.
