Abstract

The utility model discloses a testing machine in falling weight impact test on an oil branch tube protection ring, which consists of a framework, a lifting device 6, an unhooking device 7, a drop hammer and a set of three-dimensional anvil bed, and the lifting device 6 is fixed on the top of the framework through a lifting device chassis 5, and is connected with the drop hammer through the unhooking device 7. The drop hammer consists of a guide bar 8 which crosses a guide runner 9, a hammer head 11 and a weight 10. The three-dimensional anvil bed and an oblique stop 15 are all provided with a V shape groove, which are capable of sliding in the slide way of an anvil bed chassis and being fixed on a proper position. The testing machine is capable of taking an axial, radial and an angle of 45 degrees angularly falling weight test only with a set of three-dimensional anvil bed to multiple standards branch pipe screw protector without the need of changing a holding device frequently.

Description

Petroleum casing pipe protection ring drop hammer impact testing machine

The utility model relates to a kind of test unit.

At present, there is following problem in petroleum casing pipe protection ring drop hammer impact testing machine: the employing that the has two ends guidance mode that drops hammer has increased the resistance that drops hammer when discharging; What have does not have guide piece when dropping hammer decline, tumble other position behind the drop impact sample, causes to promote difficulty once more, has unsafe factor yet; When doing the impact experiment of different size, need the frequent clamping device of changing, strengthened experimental cost, reduced work efficiency.

The purpose of this utility model provides a kind of test unit, it can make things convenient for, accurately, safety inspection ground double thread protector carries out the resistance to impact check, and can reduce experimental cost greatly, increase work efficiency.

In order to realize above purpose, the utility model petroleum casing pipe protection ring drop hammer impact testing machine by frame, lifting gear, detacher, drop hammer, three-dimensional impacts anvil block and forms, frame forms by base, column, central sill and upper beam are affixed; Lifting gear is fixed in frame upper end through the lifting gear base, and is connected with dropping hammer through detacher; Drop hammer and be made up of the guide pole that passes guide plate, tup and the weights that has a pilot hole, tup is fixedlyed connected with guide pole, and weights is by being bolted on the tup, and guide plate is fixed on the centre of central sill, has the safety pin hole on the guide pole; Three-dimensional is impacted anvil block and is made up of left anvil block, right anvil block, anvil block base, have slideway on the anvil block base, and fixedly connected with bracket base, the medial surface of left side anvil block, right anvil block reaches on the inclined-plane of going up plane, diagonal cleat piece and all has the V-type groove, and can in the slideway on the anvil block base, be free to slide, and available clamping screw and sliding nut are fixing goes up in place, to be used to install the sample of different size.

This petroleum casing pipe protection ring drop hammer impact testing machine; only can axially, radially reach oblique impulse test to the enforcement of plurality of specifications casing threads protector from the horizontal by miter angle with impact anvil block once the cover three-dimensional; do not need frequently to change clamping device; easy and simple to handle; at the bottom of the experimental cost, high efficiency.Because tup has adopted axially directed rod guidance to, the frictional resistance when falling of can reducing significantly to drop hammer, the more convergence freely falling body that moves that drops hammer can satisfy the requirement of testing impact energy more accurately.

Below in conjunction with specific embodiment the utility model is described further.

Fig. 1 is a structural drawing of the present utility model.

Petroleum casing pipe protection ring drop hammer impact testing machine shown in Figure 1, by frame, lifting gear 6, detacher 7, drop hammer, three-dimensional impacts anvil block and forms, frame is by base 1, column 2, central sill 3 and 4 affixed the forming of putting the beams in place; Lifting gear 6 is selected the CD1-6A electric block for use, and is fixed in frame upper end through lifting gear base 5, is connected with dropping hammer through detacher 7; Detacher is used for release and drops hammer, and the manual release beginning is designed to double-button, to improve safe and reliable property of operation; Drop hammer and be made up of the guide pole 8 that passes guide plate 9, tup 11 and the weights 10 that has a pilot hole, tup is fixedlyed connected with guide pole, and weights is by being bolted on the tup, and guide plate 9 is fixed on the centre of central sill 3, has the safety pin hole on the guide pole; Three-dimensional is impacted anvil block and is made up of left anvil block 12, right anvil block 13, anvil block base 14, have slideway on the anvil block base, and fixedly connected with bracket base, the medial surface of left side anvil block, right anvil block reaches on the inclined-plane of going up plane, diagonal cleat piece 15 and all has the V-type groove, and can in the slideway on the anvil block base, be free to slide, and available clamping screw and sliding nut are fixing goes up in place, to be used to install the sample of different size.During test, lifting gear is by belonging to the guide pole of the part of dropping hammer, and will drop hammer is promoted to certain altitude; the energy that possesses testing requirements of the right to use; drop hammer after the release, bump is installed in the screw thread protection device sample on the three-dimensional impact anvil block, just can reach test purpose.
