Abstract
The invention relates to a device for testing feeding force and lifting force of a top-drive power head drill. At present, a device for testing the feeding force and the lifting force of the top-drive power head drill is required to reliably fix the drill, as well as ensuring the center of the power head of the drill is concentric with the testing device, but both are hard to realize, which results in that the drill shaft is likely to arch to influence the testing precision during testing the feeding force. The device comprises an oil cylinder, a force transmission core bar, a hinge bearing and a base plate, wherein the oil cylinder is arranged on the hinge bearing, and the base plate is mounted at the bottom of the hinge bearing; a piston rod of the oil cylinder is of a hollow structure and is provided internally with the force transmission core bar, and a pulling pressure sensor is mounted at the tail end of the force transmission core bar; the bottom of the base plate of the testing device is arranged on a guide rail on the drill body through a holder bearing; and a testing drilling rod held by the power head of the drill is connected with the pulling pressure sensor. With the testing device provided by the invention, the drill fixation is unnecessary; centering of the device relative to the power head of the drill is good, and thus the testing error is reduced.

Summary of the invention
The technical matters that the present invention solved provides the existing rig of a kind of solution firm loaded down with trivial details and rig and proving installation eccentricity issues, can play effectively simplify the firm program of rig, assurance drill power head and concentric being used to of proving installation test power head type drill rig feed power, pulling force proving installation.
For solving above-mentioned technical matters, the technical scheme that the present invention adopts:
A kind of be used to test power head type drill rig feed power, pulling force proving installation; Its special character is: comprise oil cylinder, power transmission core bar, rocker bar bearing, backing plate; Oil cylinder is arranged on the rocker bar bearing and the rocker bar bearing bottom is provided with backing plate; The piston rod of oil cylinder is a hollow structure, and the power transmission core bar passes and is arranged in the piston rod, and the end of power transmission core bar is provided with pull pressure sensor; The bottom of the backing plate of described proving installation is arranged on the rig fuselage guide rail through the clamper seat, and drill power head adds the test drilling rod of holding and is connected with pull pressure sensor through the drilling rod catcher.
Above-mentioned proving installation is concentric with drill power head.
Above-mentioned oil cylinder is two bar two-way cylinders.
Pass through auxiliary pipe fitting series connection ratio pressure adjustment relief valve between two hydraulic fluid ports of above-mentioned oil cylinder.
The above-mentioned power transmission core bar and the piston rod two ends of oil cylinder are provided with thrust button respectively.
Compared with prior art, beneficial effect of the present invention:
The present invention is connected with the pull pressure sensor of proving installation the test drilling rod of drill power head clamping through the drilling rod catcher; Rig is carried out and has been fed, stirred when doing; The oil cylinder piston bar plays the load effect, and this moment, pull pressure sensor reading and hydraulic pressure sensor reading can reflect that power head type drill rig feeds, the test value of pulling force.
The present invention does not need firm rig, and device is good to neutrality with drill power head, reduces test error.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the scheme of installation of the present invention when using;
1-drilling rod catcher, 2-pull pressure sensor, 3-power transmission core bar, 4-oil cylinder, 5-ratio pressure adjustment relief valve, 6-rocker bar bearing, 7-auxiliary pipe fitting, 8-backing plate, 9-clamper seat, 10-rig fuselage guide rail, 11-drill power head, 12-test drilling rod.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated.
Referring to Fig. 1,2; The present invention includes oil cylinder 4, power transmission core bar 3, rocker bar bearing 6, backing plate 8; Oil cylinder 4 is arranged on the rocker bar bearing 6 and rocker bar bearing 6 bottoms are provided with backing plate 8; The piston rod of oil cylinder 4 is a hollow structure, and power transmission core bar 3 passes and is arranged in the piston rod, and the end of power transmission core bar 3 is provided with pull pressure sensor 2; The bottom of the backing plate 8 of described proving installation is arranged on the rig fuselage guide rail 10 through clamper seat 9, and drill power head adds the test drilling rod held 12 and is connected with pull pressure sensor 2 through drilling rod catcher 1.
Above-mentioned proving installation is concentric with drill power head, can on the rig of different model, use through the backing plate 8 on the adjustment clamper seat 9, guarantees that drill power head is concentric with proving installation.
Above-mentioned oil cylinder 4 is two bar two-way cylinders.
Through auxiliary pipe fitting 7 series connection ratio pressure adjustment relief valves 5, regulate the opening of ratio pressure adjustment relief valve and can control the resistance in the oil cylinder motion, and do not need to establish fuel tank in addition between two hydraulic fluid ports of above-mentioned oil cylinder 4, simple in structure.
Above-mentioned power transmission core bar 3 is provided with thrust button respectively with the piston rod two ends of oil cylinder 4, guarantee rig carry out feed/piston rod moves with drilling rod during pulling action, and has guide effect.
Principle of work of the present invention is:
The test drilling rod 12 of drill power head 8 is carried out and is fed pulling action; Test drilling rod 12 drives pull pressure sensor 2, power transmission core bar 3 and two bar two-way cylinder 4 piston rods action through drilling rod catcher 1; Because the throttling action of the ratio pressure adjustment relief valve 5 of 4 two hydraulic fluid port series connection of two bar two-way cylinders; Two bar two-way cylinders 4 become the load that rig feeds pulling action, through regulating the opening degree of ratio pressure adjustment relief valve 5, regulate the speed that feeds pulling action; In the process of two bar two-way cylinder 4 piston rod movements, the reading of pull pressure sensor 2 is the test value that institute's survey rig has fed the ability of pulling out.
