Abstract
The utility model relates to a testing apparatus for testing a feeding force and a pulling force of a power-head-type drill. At present testing apparatuses for the feeding force and the pulling force of power-head-type drills need to fix drills stably and guarantee that power heads of drills and testing apparatuses keep concentric. But fixing drills and keeping concentricity are often difficult to achieve. When in feeding force test, a drill stem is easy to arch and test precision is affected. The testing apparatus provided by the utility model 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 a hollow structure. The force transmission core bar is passed and disposed in the piston rod. A pulling pressure sensor is mounted at the end of the force transmission core bar. The bottom of the base plate of the testing apparatus is arranged on a guide rail on the drill body through a gripper bearing. A test drill stem gripped by the drill power head is connected with the pulling pressure sensor by a drill stem connecting hand. According to the apparatus, fixing the drill is unnecessary, centering property of the apparatus with the power head of the drill is good and test errors are reduced.

Summary of the invention
The technical matters that the utility model 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 utility model 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 is located 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, the beneficial effect of the utility model:
The utility model 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 utility model does not need firm rig, and device is good to neutrality with drill power head, reduces test error.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Scheme of installation when Fig. 2 is the utility model use;

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
Referring to Fig. 1,2; The utility model comprises 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 is located 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.
The principle of work of the utility model 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.
