Description
Technical field
The present invention relates to a kind of pair of all-hydraulic continuous injection static sounding machine of oil cylinder group.
Background technology
Static sounding carries out a kind of method of soil in-situ test as the geotechnical engineering technical field, be to utilize apparatus for feeding the bottom to be equipped with the feeler lever injection soil layer of probe, estimate the basic physico mechanical characteristic of the soil body by measuring parameters such as penetration resistance and frictional force, as the modulus of deformation of soil, the allowable bearing of soil etc.According to the static sounding technical specification, require feeler lever in the process of injection soil layer, to keep continuous, stable constant speed to feed, general feed speed is 2cm/s, can obtain continuous and stable soil layer test data like this.Traditional mechanical type and fluid pressure type static sounding machine, because what adopt is single oil cylinder group oil cylinder batch (-type) feeding mode, usually the beginning at a feeler lever partly has one section tangible accelerator, between two feeler levers, there is simultaneously the pause of a period of time, be used for feed mechanism backhaul and adjunction feeler lever, the speed that so just makes feeler lever injection soil layer is not even, continuous and stable, beginning and ending segment at every feeler lever have not caused test data bad owing to injection speed reaches code requirement, have influence on obtaining of complete soil layer data.
Summary of the invention
The objective of the invention is in order to address the above problem, and provide a kind of mode of two oil cylinder group electrichydraulic control that adopts to realize the continuous constant speed ground injection of feeler lever soil layer, can improve the all-hydraulic continuous injection static sounding machine based on two oil cylinder groups of the accuracy of static sounding test data.
The present invention in order to achieve the above object, adopt following technical scheme: the all-hydraulic continuous injection static sounding machine that a kind of pair of oil cylinder group is provided, comprise oil cylinder, oild chuck, lead limit switch, frame, feeler lever and hydraulic control system, described oil cylinder adopts a oil cylinder group and b oil cylinder group to feed oil cylinder for two groups, every group have two dimensional structures identical and about the oil cylinder arranged, two group oil cylinders are cross-shaped branch two-layer being installed on the frame up and down; Two oil cylinder piston bars of a oil cylinder group connect firmly together by a crossbeam, and a oild chuck is installed on a crossbeam, below a oil cylinder group a lead limit switch are installed; Two oil cylinder piston bars of b oil cylinder group connect firmly together by the b crossbeam, and the b oild chuck is installed on the b crossbeam, below b oil cylinder group the b lead limit switch are installed; A oild chuck and b oild chuck are the clamping and the feeding force transferring part of feeler lever, and feeler lever passes through from the central bore of two oild chucks.
Two oild chucks of the present invention are the normally closed type clamp mechanism, and when fuel feeding was not given the hydraulic pressure chuck, disk spring promoted claw and clamps feeler lever in the oild chuck, when to the oild chuck fuel feeding, make the disk spring compression by oil pressure, and claw unclamps feeler lever.
Of the present inventionly below a oil cylinder group, a lead limit switch is installed, when the piston rod of a oil cylinder group feeds downwardly near terminal point, the piston rod of a oil cylinder group touches a lead limit switch, sends the command signal of a oil cylinder group commutation backhaul, and the piston rod of a oil cylinder group upwards returns; In like manner, below b oil cylinder group the b lead limit switch is installed, when the piston rod of b oil cylinder group fed downwardly near terminal point, the piston rod of b oil cylinder group touched the b lead limit switch, send the command signal of b oil cylinder group commutation backhaul, the piston rod of b oil cylinder group upwards returns.Because it is rodless cavity fuel feeding feeding and the oil cylinder cavity of resorption is the backhaul of rod chamber fuel feeding that the oil cylinder of a oil cylinder group and b oil cylinder group all adopts the oil cylinder epicoele, helping feeler lever like this obtains than roughing feed power, make the time of the time of oil cylinder drawback movement simultaneously, thereby realize feeler lever continuous uninterrupted injection campaign less than feed motion.Two group oil cylinders are by the signal detection of lead limit switch, realize the automatic switchover of feed motion and drawback movement, utilize hydraulic control system to realize oild chuck to the clamping of feeler lever with unclamp simultaneously, to cooperate the motion feeding and the drawback movement of oil cylinder.
